https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.

@Devintrix , congrats and happy lifes with your wife. this joke is for you :)
Dear Tech Support:
Last year I upgraded from Girlfriend 7.0 to Wife 1.0 and noticed that the new program began running unexpected child processing that took up a lot of space and valuable resources.
In addition, Wife 1.0 installs itself into all other programs and launches during system initialization, where it monitors all other system activity. Applications such as PokerNight 10.3, Drunken Boys Night 2.5 and Monday Night football 5.0 no longer run, crashing the system whenever selected.
I cannot seem to keep Wife 1.0 in the background while attempting to run some of my other favorite applications. I am thinking about going back to Girlfriend 7.0, but un-install does not work on this program.
Can you help me please?
Thanks,
Joe
——————————————————–
Dear Joe:
This is a very common problem men complain about but is mostly due to a primary misconception. Many people upgrade from Girlfriend 7.0 to Wife 1.0 with the idea that Wife 1.0 is merely a “UTILITIES & ENTERTAINMENT” program. Wife 1.0 is an OPERATING SYSTEM and designed by its creator to run everything.
It is unlikely you would be able to purge Wife 1.0 and still convert back to Girlfriend 7.0. Hidden operating files within your system would cause Girlfriend 7.0 to emulate Wife 1.0 so nothing is gained.
It is impossible to un-install, delete, or purge the program files from the system once installed. You cannot go back to Girlfriend 7.0 because Wife 1.0 is not designed to do this. Some have tried to install Girlfriend 8.0 or Wife 2.0 but end up with more problems than the original system.
I recommend you keep Wife 1.0 and just deal with the situation. Having Wife 1.0 installed myself, I might also suggest you read the entire section regarding General Partnership Faults (GPFs). You must assume all responsibility for faults and problems that might occur, regardless of their cause. The best course of action will be to enter the command C:\APOLOGIZE. The system will run smoothly as long as you take the blame for all the GPFs.
Wife 1.0 is a great program, but very high maintenance. Consider buying additional software to improve the performance of Wife 1.0. I recommend Flowers 2.1, Jewelry 2.2, and Chocolates 5.0.
Do not, under any circumstances, install Secretary With Short Skirt 3.3. This is not a supported application for Wife 1.0 and is likely to cause irreversible damage to the operating system.
Best of luck,

Its that time of the morning again where I get nothing done and moan about the past ... thats right its practiseSafeHex's most incompetent co-worker!!!
Today I'd like to tell you the story of "i". Interesting about "I" is that he was actually a colleague of yesterdays nominee "G" (and was present at the "java interface" video call, and agreed with G!): https://devrant.com/rants/1152317/...
"I" was the spearhead of a project to end all projects in that company. It was suppose to be a cross-platform thing but ended up only working for iOS. It was actually quite similar to this: https://jasonette.com/ (so similar i'm convinced G / I were part of this but I can't find their github ID's in it).
To briefly explain the above + what they built ... this is the worst piece of shit you can imagine ... and thats a pretty strong statement looking back at the rest of this series so far!
"I" thought this would solve all of our problems of having to build similar-ish apps for multiple customers by letting us re-use more code / UI across apps. His main solution, was every developers favourite part of writing code. I mean how often do you sit back and say:
"God damn I wish more of this development revolved around passing strings back and forth. Screw autocomplete, enums and typed classes / variables, I want more code / variables inside strings in this library!"
Yes thats right, the main part of this bullshittery was putting your entire app, into JSON, into a string and downloading it over http ... what could possibly go wrong!
Some of my issues were:
- Everything was a string, meaning we had no autocomplete. Every type and property had to be remembered and spelled perfectly.
- Everything was a string so we had no way to cmd + click / ctrl + click something to see somethings definition.
- Everything was a string so any business logic methods had to be remembered, all possible overloaded versions, no hints at param types no nothing.
- There was no specific tooling for any of this, it was literally open up xcode, create a json file and start writing strings.
- We couldn't use any of the native UI builders ... cause strings!
- We couldn't use any of the native UI layout constructs and we had to use these god awful custom layout managers, with a weird CSS feel to them.
What angered me a lot was their insistence that "You can download a new app over http and it will update instantly" ... except you can't because you can't download new business logic only UI. So its a new app, but must do 100% exactly the same thing as before.
His other achievements include:
- Deciding he didn't like apple's viewController and navigationBar classes and built his own, which was great when iOS 7 was released (changed the UI to allow drawing under the status bar) and we had no access to any of apples new code or methods, meaning everything had to be re-built from scratch.
- On my first week, my manager noticed he fucked up the login error handling on the app I was taking over. He noticed this as I was about to leave for the evening. I stayed so we could call him (he was in an earlier timezone). Rather than deal with his fucked up, he convinced the manager it would be a "great learning experience" for me to do it ... and stay in late ... while he goes home early.
- He once argued with me in front of the CEO, that his frankenstein cross-platform stuff was the right choice and that my way of using apples storyboards (and well thought out code) wasn't appropriate. So I challenged him to prove it, we got 2 clients who needed similar apps, we each did it our own way. He went 8 man weeks over, I came in 2 days under and his got slated in the app store for poor performance / issues. #result.
But rather than let it die he practically sucked off the CEO to let him improve the cross platform tooling instead.
... in that office you couldn't swing a cat without hitting a retard.
Having had to spend a lot more time working with him and more closely than most of the other nominees, at a minimum "I" is on the top of my list for needing a good punch in the face. Not for being an idiot (which he is), not for ruining so much (which he did), but for just being such an arrogant bastard about it all, despite constant failure.
Will "I" make it to most incompetent? Theres some pretty stiff competition so far
Tune in later for more practiceSafeHex's most incompetent co-worker!!!6 -
Remember the Ububtu mobile OS ?
I remember working on the community UI drive for this project. To know that something as awesome as ubuntu would come down into the form factor of a phone , was just ecstatic.
The first build was out , people liked it. People nagged a bit about the performance issues , but it was going fine. Then the second build .. then the third no one heard about and the 4th that never came.
The interface for this system was unique because after Wondows , this is the only other OS developer that embraced the one ecosystem mantra of design.
Using Ubuntu phone was natural , it was a small desktop OS.
I remember logging on to launchpad one day and seeing the Ubuntu mobile channel with it's last post " Thank you and goodbye "
It was heartbreaking , but i could understand. Like windows phone ( which if you guys weren't aware of , had APK support by the end of its lifecycle ) felt crushed under the weight of android and iOS.
Waiting for a day when there will be a third champion in game. I miss having to see Ubuntu being on my phone , but they seem to be doing great in everything else , so good on that. 😄
Ok done .. thanks30 -
1) I accepted this job for way way less money than market value.
2) Approached boss about having performance review because I had been here over 12 months and no one brought it up to me.
3) Had performance review where they offered a big raise (12% but still way under market value)
4) I countered asking for market value and showed aggregate research (30% increase)
5) A week later we meet again and they offer 23%.
6) That's where we ended at, pretty surprised they offered that much, but glad. I wasn't looking forward to looking at other jobs to catch up to market value.
7) Feeling pretty good considering I've never negotiated anything before.7 -
And, the other side, husbands 😂
——————————————————–
Dear Technical Support,
Last year I upgraded from Boyfriend 5.0 to Husband 1.0 and noticed a distinct slow down in overall system performance — particularly in the flower and jewelry applications, which operated flawlessly under Boyfriend 5.0. The new program also began making unexpected changes to the accounting modules.
In addition, Husband 1.0 uninstalled many other valuable programs, such as Romance 9.5 and Personal Attention 6.5 and then installed undesirable programs such as NFL 5.0, NBA 3.0, and Golf Clubs 4.1.
Conversation 8.0 no longer runs, and Housecleaning 2.6 simply crashes the system. I’ve tried running Nagging 5.3 to fix these problems, but to no avail.
What can I do?
Signed,
Desperate
——————————————————–
Dear Desperate:
First keep in mind, Boyfriend 5.0 is an Entertainment Package, while Husband 1.0 is an Operating System.
Please enter the command: ” C:/ I THOUGHT YOU LOVED ME” and try to download Tears 6.2 and don’t forget to install the Guilt 3.0 update.
If that application works as designed, Husband 1.0 should then automatically run the applications Jewelry 2.0 and Flowers 3.5. But remember, overuse of the above application can cause Husband 1.0 to default to Grumpy Silence 2.5, Happy Hour 7.0 or Beer 6.1.
Beer 6.1 is a very bad program that will download the Snoring Loudly Beta.
Whatever you do, DO NOT install Mother-in-law 1.0 (it runs a virus in the background that will eventually seize control of all your system resources).
Also, do not attempt to reinstall the Boyfriend 5.0 program. These are unsupported applications and will crash Husband 1.0.
In summary, Husband 1.0 is a great program, but it does have limited memory and cannot learn new applications quickly.
You might consider buying additional software to improve memory and performance. We recommend Food 3.0 and Hot Lingerie 7.7.
Good Luck,

Never have I been so furious whilst at work as yesterday, I am still super pissed about going back today but knowing it's only for another few weeks makes it baerable.
I have been the lead developer on a project for the last 3~ months and our CTO is the product owner. So every now and then he decides to just work on a feature he is interested in- fair enough I guess. But everything I have to go and clean up his horrendous code. Everything he writes is an absolute joke, it's like he is constantly in Hackathon mode "let's just copy and paste some code here, hardcoded shit there and forgot about separation of code- it all goes in 1 file".
So yesterday he added a application to the project and instead of reusing a shared data access layer he added an entirely new ORM, which is near identical to the existing ORM in use, for this one application.
Being anal about these things, the first thing I did was delete his shit and simply reference the shared library then refactor a little code to make it compatible.
WELL!! I certainly hit a nerve, he went crazy spamming messages on Slack demanding I revert as it broke ONE SINGLE QUERY that he hadn't checked in (he does 1 huge commit for 10 of everyone else's). I stuck to my principals and explained both ORM's are similar and that we only needed one, the second would cause a fragmented codebase for no benefit whatsoever.
The lead Dev was then forced to come and convince me to revert, again I refused and called out the shit quality of their code. The battle raged on via the public slack group and I could hear colleagues enjoying the heated debate, new users even started joining the group just to get in on mine and the cto's difference of opinion.
I even offered to fix his code for him if he were to commit it, obviously that was not taken well ;).
Once I finally got a luck at the cluster fuck of shit he had written it took me around 5 minutes to fix and I ever improved performance. Regardless he was having none of it. Still the demands to revert continued.
I left the office steaming after long discussions with the lead Dev caught in the middle.
Fortunately my day was salvages with a positive technical discussion that evening at a company with whome I had a job offer from.
I really hate burning bridges and have never left a company under bad terms but this dictator is making me look forward to breaking the news today I will be gone in 4 weeks.4 -
Sooo, in my 5 years of high school, I had 5 different IT teachers...
Now, in Italy Highschool goes from 14 to 19 years old, I started programming some days after becoming 13, and "programming" classes begin on the third year, so I had quite a headstart on my classmates...
Now, for the third year, I had an awesome teacher, he noticed I was ahead and... Bored, so he gave me some extra stuff to study, he's the only teacher I've learnt anything from, it was awesome, very stingy with grades, but getting a perfect score with him was so satisfying.
Fourth year, the new guy was old, very old, at least 70, his lessons were just him talking about how programming was when he was young.
But then... During the second half of the fourth year I changed class due to bullying under a teacher's advice, and HE happened...
My new IT teacher, one of the most ignorant, awful people I ever met...
He's literally the reason I only went back to that school once, because another teacher needed help with a course...
One day I made the HUGE mistake to say that his "while(i <10000000000000);" wasn't very efficient for making a delay, because it didn't free the CPU, and since then:
- I never got more than 7 out of 10 at his tests
- He insulted me in front of the whole class
- He sabotaged the oral part of my final exam, shouting that he hated D'Annunzio when he saw he was in the literature part of my thesis (needed him to connect to WW2, and the Memex, that then allowed me to start talking about PCs and programming, my thesis was about the influence of lisp on modern programming languages), loudly chatting with other teachers when I was trying to keep calm (a teacher who knows me quite well, and was there to see my "performance" thought I was going to snap at some point), distracting the english teacher when I was exposing the english part of my thesis and pressuring the commission to give me 99 instead of 100 out of 100
So yeah, he almost made me hate the only thing I'm good at, undervaluing my work and my skills, undervaluing and humiliating me as a person, and I think that if I meet him again I might spit on his face...
So yeah, my biggest "programmer enemy" was a person that then did everything in his power to make my last year and a half of highschool hell
Now I can gladly say that with the help of my tutoring, some of my university colleagues are starting to appreciate programming, and my engineer friends ask for my help when they need advices about their code, and it's giving me motivation to keep doing it and becoming a better programmer to keep up with their expectations4 -
Had an unannounced performance/progress review at work today.
I always get nervous when having those but I know my boss and lead support engineer by now so i got to relaxed mode quite fast.
Then i was getting very cold and started to shake (in combo with the slight nervousness).
That lead to extensive stuttering 😬
Apparently I put my chair right under a fucking ceiling fan thingy in my nervousness.

--- NVIDIA announces PhysX SDK 4.0, open-sources 3.4 under modified BSD license ---
NVIDIA has announced a new version, 4.0, of PhysX, their physics simulation engine.
Its new features include:
- A "Temporal Gauss-Seidel Solver (TGS)", an algorithm used in this SDK to make things such as robots, character arms, etc. more robust to move around. NVIDIA demonstrates this in the video by making their old version of PhysX, 3.4, seem like an unpredictable mess, the robot demonstrating that version smashing a game of chess.
- New filtering rules for supposedly easier scalability in scenes containing lots of both moving and static objects.
- Faster queries in scenes with actors that have a lot of shapes attached to them, improving performance.
- PhysX can now be more easily used with Cmake-based projects.
In essence, better control over scenes and actors as well as performance improvements are what's new.
Furthermore, NVIDIA has released PhysX version 3.4 under the 3-Clause-BSD-license, except for game console platforms.
As NVIDIA will release the new version on December 20th, it will also be released under the same modified BSD license as PhysX 3.4 is now.
What are your thoughts on NVIDIA making a big move towards the open-source community by releasing PhysX under the BSD license? Feel free to let us know in the comments!

Due to popular demand (and we being unable to produce a smooth performance out of JavaFX), we decided to switch to Electron for devRantFX collab. It is now called devRantron!
Relevant collab: https://devrant.io/collabs/420025/
Under the hood we are using the following techs:
- React (ReactJS, Redux, React-Router)
- Jest
- ES6 and Webpack
- MaterializeCSS
If you have knowledge about React-native or VueJS, you should be able to understand the code (eventually). If you want to contribute let me know! I will add you to our slack group :)12 -
"Thank you for choosing Microsoft!"
No Microsoft, I really didn't choose you. This crappy hardware made you the inevitable, not a choice.
And like hell do I want to run your crappy shit OS. I tried to reset my PC, got all my programs removed (because that's obviously where the errors are, not the OS, right? Certified motherfuckers). Yet the shit still didn't get resolved even after a reset. Installing Windows freshly again, because "I chose this".
Give me a break, Microshaft. If it wasn't for your crappy OS, I would've gone to sleep hours ago. Yet me disabling your shitty telemetry brought this shit upon me, by disabling me to get Insider updates just because I added a registry key and disabled a service. Just how much are you going to force data collection out of your "nothing to hide, nothing to fear" users, Microsoft?
Honestly, at this point I think that Microsoft under Ballmer might've been better. Because while Linux was apparently cancer back then, at least this shitty data collection for "a free OS" wasn't yet a thing back then.
My mother still runs Vista, an OS that has since a few months ago reached EOL. Last time she visited me I recommended her to switch to Windows 7, because it looks the same but is better in terms of performance and is still supported. She refused, because it might damage her configurations. Granted, that's probably full of malware but at this point I'm glad she did.
Even Windows 7 has telemetry forcibly enabled at this point. Vista may be unsupported, but at least it didn't fall victim to the current status quo - data mining on every Microshaft OS that's still supported.
Microsoft may have been shady ever since they pursued manufacturers into defaulting to their OS, and GPU manufacturers will probably also have been lobbied into supporting Windows exclusively. But this data mining shit? Not even the Ballmer era was as horrible as this. My mother may not realize it, but she unknowingly avoided it.6 -
Our web department was deploying a fairly large sales campaign (equivalent to a ‘Black Friday’ for us), and the day before, at 4:00PM, one of the devs emails us and asks “Hey, just a heads up, the main sales page takes almost 30 seconds to load. Any chance you could find out why? Thanks!”
We click the URL they sent, and sure enough, 30 seconds on the dot.
Our department manager almost fell out of his chair (a few ‘F’ bombs were thrown).
DBAs sit next door, so he shouts…
Mgr: ”Hey, did you know the new sales page is taking 30 seconds to open!?”
DBA: “Yea, but it’s not the database. Are you just now hearing about this? They have had performance problems for over week now. Our traces show it’s something on their end.”
Mgr: “-bleep- no!”
Mgr tries to get a hold of anyone …no one is answering the phone..so he leaves to find someone…anyone with authority.
4:15 he comes back..
Mgr: “-beep- All the web managers were in a meeting. I had to interrupt and ask if they knew about the performance problem.”
Me: “Oh crap. I assume they didn’t know or they wouldn’t be in a meeting.”
Mgr: “-bleep- no! No one knew. Apparently the only ones who knew were the 3 developers and the DBA!”
Me: “Uh…what exactly do they want us to do?”
Mgr: “The –bleep- if I know!”
Me: “Are there any load tests we could use for the staging servers? Maybe it’s only the developer servers.”
DBA: “No, just those 3 developers testing. They could reproduce the slowness on staging, so no need for the load tests.”
Mgr: “Oh my –bleep-ing God!”
4:30 ..one of the vice presidents comes into our area…
VP: “So, do we know what the problem is? John tells me you guys are fixing the problem.”
Mgr: “No, we just heard about the problem half hour ago. DBAs said the database side is fine and the traces look like the bottleneck is on web side of things.”
VP: “Hmm, no, John said the problem is the caching. Aren’t you responsible for that?”
Mgr: “Uh…um…yea, but I don’t think anyone knows what the problem is yet.”
VP: “Well, get the caching problem fixed as soon as possible. Our sales numbers this year hinge on the deployment tomorrow.”
- VP leaves -
Me: “I looked at the cache, it’s fine. Their traffic is barely a blip. How much do you want to bet they have a bug or a mistyped url in their javascript? A consistent 30 second load time is suspiciously indicative of a timeout somewhere.”
Mgr: “I was thinking the same thing. I’ll have networking run a trace.”
4:45 Networking run their trace, and sure enough, there was some relative path of ‘something’ pointing to a local resource not on development, it was waiting/timing out after 30 seconds. Fixed the path and page loaded instantaneously. Network admin walks over..
NetworkAdmin: “We had no idea they were having problems. If they told us last week, we could have identified the issue. Did anyone else think 30 second load time was a bit suspicious?”
4:50 VP walks in (“John” is the web team manager)..
VP: “John said the caching issue is fixed. Great job everyone.”
Mgr: “It wasn’t the caching, it was a mistyped resource or something in a javascript file.”
VP: “But the caching is fixed? Right? John said it was caching. Anyway, great job everyone. We’re going to have a great day tomorrow!”
VP leaves
NetworkAdmin: “Ouch…you feel that?”
Me: “Feel what?”
NetworkAdmin: “That bus John just threw us under.”
Mgr: “Yea, but I think John just saved 3 jobs. Remember that.”4 -
Been reviewing ALOT of client code and supplier’s lately. I just want to sit in the corner and cry.
Somewhere along the line the education system has failed a generation of software engineers.
I am an embedded c programmer, so I’m pretty low level but I have worked up and down and across the abstractions in the industry. The high level guys I think don’t make these same mistakes due to the stuff they learn in CS courses regarding OOD.. in reference how to properly architect software in a modular way.
I think it may be that too often the embedded software is written by EEs and not CEs, and due to their curriculum they lack good software architecture design.
Too often I will see huge functions with large blocks of copy pasted code with only difference being a variable name. All stuff that can be turned into tables and iterated thru so the function can be less than 20 lines long in the end which is like a 200% improvement when the function started out as 2000 lines because they decided to hard code everything and not let the code and processor do what it’s good at.
Arguments of performance are moot at this point, I’m well aware of constraints and this is not one of them that is affected.
The problem I have is the trying to take their code in and understand what’s its trying todo, and todo that you must scan up and down HUGE sections of the code, even 10k+ of line in one file because their design was not to even use multiple files!
Does their code function yes .. does it work? Yes.. the problem is readability, maintainability. Completely non existent.
I see it soo often I almost begin to second guess my self and think .. am I the crazy one here? No. And it’s not their fault, it’s the education system. They weren’t taught it so they think this is just what programmers do.. hugely mundane copy paste of words and change a little things here and there and done. NO actual software engineers architecture systems and write code in a way so they do it in the most laziest, way possible. Not how these folks do it.. it’s like all they know are if statements and switch statements and everything else is unneeded.. fuck structures and shit just hard code it all... explicitly write everything let’s not be smart about anything.
I know I’ve said it before but with covid and winning so much more buisness did to competition going under I never got around to doing my YouTube channel and web series of how I believe software should be taught across the board.. it’s more than just syntax it’s a way of thinking.. a specific way of architecting any software embedded or high level.
Anyway rant off had to get that off my chest, literally want to sit in the corner and cry this weekend at the horrible code I’m reviewing and it just constantly keeps happening. Over and over and over. The more people I bring on or acquire projects it’s like fuck me wtf is this shit!!! Take some pride in the code you write!16 -
Team quarterly capacity planning:
- Confluence document created with a big table (+100 rows) by product / business. Each row is something that needs to be worked on for the coming quarter.
- Row 1 could be an Epic with 15 tickets attached. Row 2 could be adding a single log to our analytics. No consistency.
- For each row, we create a separate confluence document with the "technical details". 75% of the time these remain blank. 1% of the time there is something useful, the rest its a slightly longer version of the description from the bigger document.
- Each row gets a high level estimate by the leads. 50% of the time without sufficient background info to actually do get it accurate.
- These are then copied into the teams excel spreadsheet, where it will calculate if we are over/under capacity.
- We will go backwards and forwards between confluence and excel until we are "close enough" to under capacity without being too much.
- Once done, we then need to copy them into the org/division's excel spreadsheet. This document is huge, has every team on it and massive 50pt text saying "Do not put a filter on this document".
- Jira tickets + Epics will now be created for each one, with all the data be copied over by hand, bit by bit, by product. Often missing something.
- Last week, at the end of this process for Q2 (2 weeks late), 6 of the leads were asked to attend a 30 minute meeting to discuss how to group the line items together because we had too many for the bigger excel spreadsheet.
- This morning I was told business weren't happy with one of our decisions to delay one line item. Although they were all top priority (P0), one of them was actually higher than that again (P-1?) and we need to work it back in.
... so back to step 1
- Mid way through Q2, a new document will be created for Q3. Work items that didn't make the cut will be manually copied from one to the other. 50/50 whether anything that didn't get done on time in Q2 will make its way to the Q3 doc.
- "Tech excellence" / "Tech debt" items (unit/UI tests, documentation, logging, performance, stability etc) will never be copied over. Because product doesn't understand them and assumes therefore that they are unimportant.
==================
PS: I'd like to say this was a rare event for Q2, but no. Q4 and Q1 were so bad, we were made assurances from the director of engineering that he would fix this process for Q2. This is the new and improved process (I shit you not) that has resulted in nothing tangible.7 -
Like most people I needed some extra cash during uni, so I proceeded to learn CSS + Photoshop (yeah, I know). Followed by PHP and WordPress.
It can be a very shitty platform until you realize that you can stop combining plug-ins from all over the place with dubious code quality and roll your own.
Anyhow I kept at it until I was able to join a niche company doing a quite popular caching plug-in for WP (yeah, W3 Total) when I suddenly became *very* interested in anything and everything performance.
This landed me a very cozy consulting gig in the Nordics - they were using WP for an elephant-traffic website and had run into a myriad of perf issues.
Fixing them and breaking the monolith awarded me with skills in nodejs, linux, asynchronous caching among others.
I was soon in charge with managing the dev boxes for the entire team, and when the main operations dude left, I was promoted to owning the entire platform. (!) Tinkering with Linux for most of my life really came in handy here. (remember Debian potato?)
Used saltstack + aws cloudformation to achieve full parity between all environments. Learned myself some python and all various tips and tricks which in the end amounted to 90% reduction in time-to-first-byte and considerable cost savings.
By the end of the 2yr contract I had turned myself into a fullstack systems engineer and never looked back.
Lawyers not getting along resulted in us having to abandon NewRelic, so I got to learn and deploy the ELK stack as a homegrown replacement, which was super-fun.
Now I work in the engineering effectiveness department of a Swedish fintech unicorn where all languages under the Sun are an option (tho we prefer Python), so the tech stack is unlimited. Infinite tools and technologies, but with strong governing principles and with performance always in mind so as to pick the right tool for the job.
It's like that childhood feeling when you've just dumped a ton of Lego on the floor and are about to build something massive.
I guess the morale here is however disappointed you feel by your current stack - don't. Always strive to make things better, faster, more decoupled, easier to test, etc. and always challenge yourself to go outside the comfort zone.6 -

Dear Current Workplace,
Fuck you, for the reasons enumerated below.
Fuck your enterprise grey blue offices, the stifling warm air of a hundreds of bodies and sub par "development laptops".
Fuck your shitty carbonated water machines which were a cost saving measure over decent drinkable water.
Fuck your fake "flexi time", "you can do home office whenever you want" bullshit. You're still inviting me to mandatory meetings at 09:00 regularly.
Fuck your shitty, in house, third part IT provider sister company. They're the worst of all worlds. If it was in company, we'd get to give out to them, if it was an external company we'd fire them. And yes, when I quit I will quote the dumpster fire that is our corporate VPN as a major factor.
Fuck your cheery, bland, enterprise communication. Words coming under the corporate letterhead seem to lose all association with meaning. Agile, communication, open are things you write and profess to respect, but it seems your totally lack understanding of their meaning.
Fuck your client driven development. Sometime you actually have to fix the foundations before you can actually add new features. And fuck you management who keep on asking "why are there so many bugs and why is it always taking longer to deliver new releases". Because of you, you fucknuts, Because you can't say "NO" to the customer. Because you never listen to your own experienced developers.
Fuck your bullshit "code quality is important to us" line. If it's so important, then let us fix the heap of shit you're selling so that it works like a quasi functional program.
Fuck you development environment which has 250 projects in a single VS solution. Which takes 5mins plus to compile on a quad core i7 with 32 gb of ram.
Fuck this bullshit ball of mud "architecture". I spend most of my time trying to figure out where the logic should go and the rest of the time writing converters between different components. All because 7 years ago some idiot "architect" made a decision that they didn't have to live with.
Actually, fuck that guy in particular. Yeah, that guy who was the responsible architect for the project for 4 years and not once opened the solution to look a the code.
Fuck the manual testing of every business process. Manual setup of the entities takes 10mins plus and then when you run, boom either no message or some bullshit error code.
Fuck the antiquated technology choices which cause loads of bugs and slow down development. Fuck you for forcing me to do manual tests of another developers code at 20:00 on a Friday night because we can't get our act together to do this automatically.
Fuck you for making sure it's very clear I'm never going to be anything but a code monkey in this structure. Managers are brought in from outside.
Fuck you for being surprised that it's hard to hire competent developers in this second rate, overpriced town. It's hard to hire anywhere but this bland shithole would have anyone with half a clue running away at top speed.
Fuck you for valuing long hours and loyalty over actual performance. That one guy who everyone hated and was totally incompetent couldn't even get himself fired. He had to quit.
Fuck you for your mediocrity.
Fuck you for being the only employer for my skill-set in the region; paying just well enough that changing jobs locally doesn't make sense, but badly enough that it's difficult to move.
Fuck you for being the stable "safe" option so that any move is "risky".
Fuck your mediocrity.
Fuck you for being something I think about when I'm not at work. Not only is it shit from 9 to 5 you manage to suck the joy out of everything else in my life as well?
Fuck you for making me feel like a worse developer every day I work here. Fuck you for making every day feel like a personal and professional failure. Fuck you for making me seriously leave a career I love for something, anything else.
Fuck you for making the most I can hope for when I get up in the morning is to just make it until the night.6 -
- Be me (Dev)
- Develop website for client that has an online payment integration.
- Notice there is no one for QA and testing.
- Try to raise voice about it but get shot down by management.
- Get order to push the project to production (because the deadline has arrived, therefore the project must be ready)
- Production performance has an error margin of 15% (customers getting their card over/under charged)
- Get blamed and flamed for everything cuz well, its all the dev's fault.

So, I found this :
Dear Tech Support:
Last year I upgraded from Girlfriend 7.0 to Wife 1.0. I soon noticed that the new program began unexpected child processing that took up a lot of space and resources. In addition, Wife 1.0 installed itself into all other programs and now monitors all other system activity. Applications such as Poker Night 10.3, Football 5.0, HuntingAndFishing 7.5, and Racing 3.6. I can't seem to keep Wife 1.0 in the background while attempting to run my favorite applications. I'm thinking about going back to Girlfriend 7.0, but the uninstall doesn't work on Wife 1.0. Please help!
Thanks ...Troubled User

REPLY:
Dear Troubled User:
This is a very common problem. Many people upgrade from Girlfriend 7.0 to Wife 1.0, thinking that it is just a Utilities and Entertainment program. Wife 1.0 is an OPERATING SYSTEM and is designed by its Creator to run EVERYTHING!!! It is also impossible to delete Wife 1.0 and to return to Girlfriend 7.0. It is impossible to uninstall, or purge the program files from the system once installed. You cannot go back to Girlfriend 7.0 because Wife 1.0 is designed not to allow this. Look in your Wife 1.0 manual under Warnings-Alimony-Child Support. I recommend that you keep Wife 1.0 installed and work on improving the configuration. I suggest installing the background application YesDear 99.0 to alleviate software augmentation.
The best course of action is to enter the command C:\APOLOGIZE because ultimately you will have to do this before the system will return to normal anyway.
Wife 1.0 is a great program, but it tends to be very high maintenance. Wife 1.0 comes with several support programs, such as CleanAndSweep 3.0, CookIt 1.5 and DoBills 4.2. However, be very careful how you use these programs. Improper use will cause the system to launch the program NagNag 9.5. Once this happens, the only way to improve the performance of Wife 1.0 is to purchase additional software. I recommend Flowers 2.1 and Diamonds 5.0, but beware because sometimes these applications can be expensive.
WARNING!!! DO NOT, under any circumstances, install SecretaryWithShortSkirt 3.3. This application is not supported by Wife 1.0 and will cause irreversible damage to the operating system.
WARNING!!! Attempting to install NewGirlFriend 8.8 along with Wife 1.0 will crash the system.
(see Wife 1.0 manual, Apologize, High Maintenance & Secretary with Short Skirt)7 -
Saw this on Facebook and couldn't help but share here! 😂
A young woman submitted the tech support message below (about her relationship to her husband) presumably did it as a joke…
The query:
Dear Tech Support,
’Last year I upgraded from Boyfriend 5.0 to Husband 1.0 and noticed a distinct slowdown in overall system performance, particularly in the flower and jewelry applications, which operated flawlessly under Boyfriend 5.0.
In addition, Husband 1.0 uninstalled many other valuable programs, such as: Romance 9.5 and Personal Attention 6.5, and then installed undesirable programs such as: NBA 5.0, NFL 3.0 and Golf Clubs 4.1.
Conversation 8.0 no longer runs, and House cleaning 2.6 simply crashes the system. Please note that I have tried running Nagging 5.3 to fix these problems, but to no avail.
What can I do?
Signed,
Desperate
The response (that came weeks later out of the blue):
Dear Desperate,
“First keep in mind, Boyfriend 5.0 is an Entertainment Package, while Husband 1.0 is an operating system. Please enter command: I thought you loved me.html and try to download Tears 6.2 and do not forget to install the Guilt 3.0 update. If that application works as designed, Husband 1.0 should then automatically run the applications Jewelry 2.0 and Flowers 3.5.
However, remember, overuse of the above application can cause Husband 1.0 to default to Grumpy Silence 2.5, Happy Hour 7.0 or Beer 6.1. Please note that Beer 6.1 is a very bad program that will download the Farting and Snoring Loudly Beta.
Whatever you do, DO NOT, under any circumstances, install Mother-In-Law 1.0 (it runs a virus in the background that will eventually seize control of all your system resources.)
In addition, please, do not attempt to re-install the Boyfriend 5.0 program. These are unsupported applications and will crash Husband 1.0.
In summary, Husband 1.0 is a great program, but it does have limited memory and cannot learn new applications quickly. You might consider buying additional software to improve memory and performance. We recommend: Cooking 3.0.Good Luck!’
Good Luck!3 -
I finally fucking did it!
I strapped up, strapped in, strapped on... uh wait what?
I finally made the full dedicated switch to linux on my personal computer. Blew away Windows and installed linux. I was able to get about 95% of the games that I actually play on PC to run under a combo of proton/lutris-wine.
I feel like after working in a (primarily) linux shop for almost 2 years now, I've learned enough to be able to actually troubleshoot if/when something goes wonky. I've been a windows/sysadmin type in my career for about 8 years and only touched small bits of linux here and there or for fun little projects like a retropie setup.
But thanks to this gig I'm working at now, as a devops engineer, I've learned so got'damn much about linux and I've been developing scripts/tools that run on linux I figured I could, or better yet 'should', take the full plunge.
So, I've decided that if there's something I absolutely need on Windows that Linux doesn't support, instead of knee-jerking and going back to Windows, I'm going to just setup a VM of windows and daily drive Linux from now on.
Some gfx tweaks for games were definitely necessary, it's still not quite as plug and play as Windows for games, but the fact that it only took like 1.5 hours to sort out all of my games performance is really impressive. Especially, considering none of these games actually supports linux out of the box and Wine/Proton is being used to get them to work.9 -
NEW 6 Programming Language 2k16
1. Go
Golang Programming Language from Google
Let's start a list of six best new programming language and with Go or also known by the name of Golang, Go is an open source programming language and developed by three employees of Google and the launch in 2009, very cool just 3 people.
Go originated and developed from the popular programming languages such as C and Java, which offers the advantages of compact notation and aims to keep the code simple and easy to read / understand. Go language designers, Robert Griesemer, Rob Pike and Ken Thompson, revealed that the complexity of C ++ into their main motivation.
This simple programming language that we successfully completed the most tasks simply by librariesstandar luggage. Combining the speed of pemrogramandinamis languages such as Python and to handalan of C / C ++, Go be the best tools for building 'High Volume of distributed systems'.
You need to know also know, as expressed by the CTO Tokopedia namely Mas Leon, Tokopedia will switch to GO-lang as the main foundation of his system. Horrified not?
eh not watch? try deh see in the video below:

2. Swift
Swift Programming Language from Apple
Apple launched a programming language Swift ago at WWDC 2014 as a successor to the Objective-C. Designed to be simple as it is, Swift focus on speed and security.
Furthermore, in December 2015, Swift Apple became open source under the Apache license. Since its launch, Swift won eye and the community is growing well and has become one of the programming languages 'hottest' in the world.
Learning Swift make sure you get a brighter future and provide the ability to develop applications for the iOS ecosystem Apple is so vast.

3. Rust
Rust Programming Language from Mozilla
Developed by Mozilla in 2014 and then, and in StackOverflow's 2016 survey to the developer, Rust was selected as the most preferred programming language.
Rust was developed as an alternative to C ++ for Mozilla itself, which is referred to as a programming language that focus on "performance, parallelisation, and memory safety".
Rust was created from scratch and implement a modern programming language design. Its own programming language supported very well by many developers out there and libraries.
4. Julia
Julia Programming Language
Julia programming language designed to help mathematicians and data scientist. Called "a complete high-level and dynamic programming solution for technical computing".
Julia is slowly but surely increasing in terms of users and the average growth doubles every nine months. In the future, she will be seen as one of the "most expensive skill" in the finance industry.
5. Hack
Hack Programming Language from Facebook
Hack is another programming language developed by Facebook in 2014.
Social networking giant Facebook Hack develop and gaungkan as the best of their success. Facebook even migrate the entire system developed with PHP to Hack
Facebook also released an open source version of the programming language as part of HHVM runtime platform.
6. Scala
Scala Programming Language
Scala programming termasukbahasa actually relatively long compared to other languages in our list now. While one view of this programming language is relatively difficult to learn, but from the time you invest to learn Scala will not end up sad and disappointing.
The features are so complex gives you the ability to perform better code structure and oriented performance. Based programming language OOP (Object oriented programming) and functional providing the ability to write code that is capable of evolving. Created with the goal to design a "better Java", Scala became one behasa programming that is so needed in large enterprises.3 -
Best code performance incr. I made?
Many, many years ago our scaling strategy was to throw hardware at performance problems. Hardware consisted of dedicated web server and backing SQL server box, so each site instance had two servers (and data replication processes in place)
Two servers turned into 4, 4 to 8, 8 to around 16 (don't remember exactly what we ended up with). With Window's server and SQL Server licenses getting into the hundreds of thousands of dollars, the 'powers-that-be' were becoming very concerned with our IT budget. With our IT-VP and other web mgrs being hardware-centric, they simply shrugged and told the company that's just the way it is.
Taking it upon myself, started looking into utilizing web services, caching data (Microsoft's Velocity at the time), and a service that returned product data, the bottleneck for most of the performance issues. Description, price, simple stuff. Testing the scaling with our dev environment, single web server and single backing sql server, the service was able to handle 10x the traffic with much better performance.
Since the majority of the IT mgmt were hardware centric, they blew off the results saying my tests were contrived and my solution wouldn't work in 'the real world'. Not 100% wrong, I had no idea what would happen when real traffic would hit the site.
With our other hardware guys concerned the web hardware budget was tearing into everything else, they helped convince the 'powers-that-be' to give my idea a shot.
Fast forward a couple of months (lots of web code changes), early one morning we started slowly turning on the new framework (3 load balanced web service servers, 3 web servers, one sql server). 5 minutes...no issues, 10 minutes...no issues,an hour...everything is looking great. Then (A is a network admin)...
A: "Umm...guys...hardly any of the other web servers are being hit. The new servers are handling almost 100% of the traffic."
VP: "That can't be right. Something must be wrong with the load balancers. Rollback!"
A:"No, everything is fine. Load balancer is working and the performance spikes are coming from the old servers, not the new ones. Wow!, this is awesome!"
<Web manager 'Stacey'>
Stacey: "We probably still need to rollback. We'll need to do a full analysis to why the performance improved and apply it the current hardware setup."
A: "Page load times are now under 100 milliseconds from almost 3 seconds. Lets not rollback and see what happens."
Stacey:"I don't know, customers aren't used to such fast load times. They'll think something is wrong and go to a competitor. Rollback."
VP: "Agreed. We don't why this so fast. We'll need to replicate what is going on to the current architecture. Good try guys."
<later that day>
VP: "We've received hundreds of emails complementing us on the web site performance this morning and upset that the site suddenly slowed down again. CEO got wind of these emails and instructed us to move forward with the new framework."
After full implementation, we were able to scale back to only a few web servers and a single sql server, saving an initial $300,000 and a potential future savings of over $500,000. Budget analysis considering other factors, over the next 7 years, this would save the company over a million dollars.
At the semi-annual company wide meeting, our VP made a speech.
VP: "I'd like to thank everyone for this hard fought journey to get our web site up to industry standards for the benefit of our customers and stakeholders. Most of all, I'd like to thank Stacey for all her effort in designing and implementation of the scaling solution. Great job Stacy!"
<hands her a blank white envelope, hmmm...wonder what was in it?>
A few devs who sat in front of me turn around, network guys to the right, all look at me with puzzled looks with one mouth-ing "WTF?"9 -
On negotiation and signing contract
================================
manager: yes you will work 8 hours a day from Tatta hours to Tat tat ta hours.

Rant!
Been working on 'MVP' features of a new product for the past 14 months. Customer has no f**king clue on how to design for performance. An uncomfortable amount of faith was placed on the ORM (ORMs are not bad as long as you know what you are doing) and the magic that the current framework provides. (Again, magic is good so long as you understand what happens behind the smoke and mirrors - but f**k all that... coz hey, productivity, right?). Customer was so focussed on features that no one ever thought of giving any attention to subtler things like 'hey, my transaction is doing a gazillion joins across trizillion tables while making a million calls to the db - maybe I should put more f**king thought into my design.' We foresaw performance and concurrency issues and raised them way ahead of the release. How did the customer respond? By hiring a performance tester. Fair enough - but what did that translate into? Nothing. Nada. Zilch. Hiring a perf tester doesn't automagically fix issues. The perf tester did not have a stable environment, a stable build or anything that is required to do a test with meaningful results. As the release date approached, the customer launched a pilot and things started failing spectacularly with the system not able to support more than 15 concurrent users. WTF! (My 'I told you so' moment) Emails started flying in all directions and the hunt for the scapegoat was on (I'm a sucker for CYA so I was covered). People started pointing in all directions but no one bothered to take a step back and understand what was causing the issues. Numero uno reason for transaction failure was deadlocks. We were using a proprietary DB with kickass tooling. No one bothered to use the tooling to understand what was the resource in contention let alone how to fix the contention. Absolute panic - its like they just froze. Debugging shit and doing the same thing again and again just so that management knew they were upto something. Most of the indexes had a fragmentation of 99.8% - I shit you not. Anywho, we now have a 'war room' where the perf tester needs to script the entire project by tonight and come up with some numbers that will amount to nothing while we stay up and keep profiling the shit out of the application under load.
Lessons learnt - When you foresee a problem make a LOT of noise to get people to act upon it and not wait till it comes back and bites you in the ass. Better yet, try not to get into a team where people can't understand the implications of shitty design choices. War room my ass!3 -
First rant here, and it's going to be a query to the more professional and experienced members of society (most of you).
I am currently a Sys Admin for a major company, and I develop at night. My primary employment at the moment is the sys admin job (and I code for extra money at nights).
I wanted to start a development department at the company that I am working at, but it was turned turned down. It was stated that we are not branching in development, and that we should stick to our server implementation and support. This was a prompt to me wanting to start studying officially (I wanted to get qualified in JAVA, so that I had some paper behind my name when I looked for another job). HR and my directors outright denied me the ability to study through them (they pay for studies for employees) and I was more than fine with this.
I took a loan and paid for the studies myself. Can't crush a dream, you know?
The director caught wind of me studying, and now has demanded that I develop him a mobile application for the company. I told him that I am not a mobile developer, and that it didn't fall into my key performance areas.
Note, I do my coding on own time, on my own device, and never at work. It's fully my intellectual property. It also in no way interferes with my work during the day, and has NO conflict with my contract this side.
He sent an email yesterday, this is after two months. He is now stating that I WILL do the application, and he has CCd HR and two directors.
I don't want to do the app for this company, I spoke to HR previously about this, and she said that I should try and quote it under my own company name (which I did, but it was denied as it was "too expensive").
Now I am being forced to do something that is COMPLETELY out of my roles and responsibilities, something that this company has ABSOLUTELY no desire to go into further on, and he is basically letting me know that if I don't do it, he is going to start messing with my pay.
I really don't want to do this, and I cannot afford to make my secondary job my primary at the moment. The problem is, too, that I don't have the time during the day to develop AND do my sys admin tasks (I manage more than 300 servers, and 5000 devices).
What can I do in this instance? Or what would you guys recommend, in your experience?
Sorry for the noob question, but I don't know what to do.19 -
Static HTML pages are better than "web apps".
Static HTML pages are more lightweight and destroy "web apps" in performance, and also have superior compatibility. I see pretty much no benefit in a "web app" over a static HTML page. "Web apps" appear like an overhyped trend that is empty inside.
During my web browsing experience, static HTML pages have consistently loaded faster and more reliably, since the browser is immediately served with content useful for consumption, whereas on JavaScript-based web "apps", the useful content comes in **last**, after the browser has worked its way through a pile of script.
For example, an average-sized Wikipedia article (30 KB wikitext) appears on screen in roughly two seconds, since MediaWiki uses static HTML. Everipedia, in comparison, is a ReactJS app. Guess how long that one needs. Upwards of three times as long!
Making a page JavaScript-based also makes it fragile. If an exception occurs in the JavaScript, the user might end up with a blank page or an endless splash screen, whereas static HTML-based pages still show useful content.
The legacy (2014-2020) HTML-based Twitter.com loaded a user profile in under four seconds. The new react-based web app not only takes twice as long, but sometimes fails to load at all, showing the error "Oops something went wrong! But don't fret – it's not your fault." to be displayed. This could not happen on a static HTML page.
The new JavaScript-based "polymer" YouTube front end that is default since August 2017 also loads slower. While the earlier HTML-based one was already playing the video, the new one has just reached its oh-so-fancy skeleton screen.
It would once have been unthinkable to have a website that does not work at all without JavaScript, but now, pretty much all popular social media sites are JavaScript-dependent. The last time one could view Twitter without JavaScript and tweet from devices with non-sophisticated browsers like Nintendo 3DS was December 2020, when they got rid of the lightweight "M2" mobile website.
Sometimes, web developers break a site in older browser versions by using a JavaScript feature that they do not support, or using a dependency (like Plyr.js) that breaks the site. Static HTML is immune against this failure.
Static HTML pages also let users maximize speed and battery life by deactivating JavaScript. This obviously will disable more sophisticated site features, but the core part, the text, is ready for consumption.
Not to mention, single-page sites and fancy animations can be implemented with JavaScript on top of static HTML, as GitHub.com and the 2018 Reddit redesign do, and Twitter's 2014-2020 desktop front end did.
From the beginning, JavaScript was intended as a tool to complement, not to replace HTML and CSS. It appears to me that the sole "benefit" of having a "web app" is that it appears slightly more "modern" and distinguished from classic web sites due to use of splash screens and lack of the browser's loading animation when navigating, while having oh-so-fancy loading animations and skeleton screens inside the website. Sorry, I prefer seeing content quickly over the app-like appearance of fancy loading screens.
Arguably, another supposed benefit of "web apps" is that there is no blank page when navigating between pages, but in pretty much all major browsers of the last five years, the last page observably remains on screen until the next navigated page is rendered sufficiently for viewing. This is also known as "paint holding".
On any site, whenever I am greeted with content, I feel pleased. Whenever I am greeted with a loading animation, splash screen, or skeleton screen, be it ever so fancy (e.g. fading in an out, moving gradient waves), I think "do they really believe they make me like their site more due to their fancy loading screens?! I am not here for the loading screens!".
To make a page dependent on JavaScript and sacrifice lots of performance for a slight visual benefit does not seem worthed it.

Jeremy Keith makes this point brilliantly.

I once had a PM who would consistently ask us to fix one off "bugs" (read little design tweaks). He wouldn't even bother to write them down anywhere. He once came over and asked why we hadn't fixed one of his bugs. We had no idea what he was talking about. According to him, we were supposed to organize and prioritize according to his whim. He never logged into our task management system.
When it finally came time to sell off our work to some of the business owners, we showed some of the "bug fixes" we did because that's all we ever heard we were supposed to do. The business owners were mad that we hadn't done anything they had asked us to do. PM throws us under the bus saying that we didn't know how to do our jobs and that we never listened to him. I was so glad when he moved to be lead of the QA department. Then I wasn't so glad.
He would have bug quotas that his team would have to meet. He pitted the entire QA team against all of the devs saying things like, "All the devs suck at coding. It's our job to save the company and the world from their buggy software." He got the only good QA guy fired because he faked a bunch of documents stating that they had had performance reviews and no improvement was made (these meeting never actually took place), and that he hadn't been meeting his big quotas. He was outside of our department and was buddy buddy with one of the C-levels, so his word trumped ours.
Then one glorious day, after I had already left the company, his department was absolved into the technology group. That same day was the day he was fired.
I kind of pity him. I didn't know if he had a family, but how can a man such as that support his family? Perhaps he doesn't have a good relationship with his wife and that's why he sucked at his job?1 -

Most obnoxious company process: The newly introduced promotion process at my ex-employer.
Originally they had a run-of-the-mill process. You and your boss reviewed your performance independently, then spent an hour to compare results. If you agreed to have proven yourself, your boss did some remaining paperwork (iow he did his job) and done.
Under the guise of transparency, fairness and autonomy of employees this was changed to:
You had to find three coworkers willing to review you (favorably). You collected their feedback, processed that (strengths, "opportunities for improvement", etc) and presented it to your boss for review. These were the first two steps of four in total, of which I've forgotten the other details tbh. It became pretty ridiculous with you defining "progress indicators", your boss's boss involved in another review round and what not.
The true purpose was clear: Delaying promotions as long as possible, making the employees do all the work, and being able to just say "no" at any point. I don't know how intellectually superior managers and HR viewed themselves, because literally none of my coworkers bought this as an improvement.
But, yeah, that became the new process at a company too big to fail.1 -
If they followed my suggestion and went straight to debugging the server issues they would have been solved it from week 1 and everyone would have thought the migration had a minor performance hiccup. In fact, we have already done such at least twice before and nobody batted an eye.
Instead they self-labelled the migration a failure on first error, setting the stage for apologizing to the client, and put themselves on the spot for a whole staging / production signoff, replication / backup worfklow, almost a blue-green "seamless" deployment reminiscent of DigitalOcean.
Well they're not DigitalOcean, and anyone who has spent any time understanding users knows they will not participate in "new system" tests long enough to find or report issues.
So of course the migration stretched out to almost three months up until the whole reason for the migration - the rapidly escalating risk of the old provider disappearing - hit like a freight train and now they have to go through the problem of debugging the server like I told them to on week 1. Only this time they've set the client mindset against it, lost any chance of reverting, have had grave risk for data loss, and are under pressure to debug other people's code in real-time.
This is why I don't trust devs to do ops. A dev's first solution to any problem is to throw tech at it. -

Guys, we need talk raw performance for a second.
Fair disclaimer - if you are for some reason intel worker, you may feel offended.
I have one fucking question.
What's the point of fucking ultra-low-power-extreme-potato CPUs like intel atoms?
Okay, okay. Power usage. Sure. So that's one.
Now tell me, why in the fucking world anyone would prefer to wait 5-10 times more for same action to happen while indeed consuming also 5-10 times less power?
Can't you just tune down "big" core and call it a day? It would be around.. a fuckton faster. I have my i7-7820HK cpu and if I dial it back to 1.2Ghz my WINDOWS with around lot of background tasks machine works fucking faster than atom-powered freaking LUBUNTU that has only firefox open.
tested i7-7820hk vs atom-x5-z8350.
opening new tab and navigating to google took on my i7 machine a under 1 second, and atom took almost 1.5 second. While having higher clock (turbo boost)
Guys, 7820hk dialled down to 1.2 ghz; 0.81v
Seriously.
I felt everything was lagging. but OS was much more responsive than atom machine...
What the fuck, Intel. It's pointless. I think I'm not only one who would gladly pay a little bit more for such difference.
i7 had clear disadvantages here, linux vs windows, clear background vs quite a few processes in background, and it had higher f***ng clock speed.
TL;DR
Intel atom processors use less power but waste a lot of time, while a little bit more power used on bigger cpu would complete task faster, thus atoms are just plain pointless garbage.
PS.
Tested in frustration at work, apparently they bought 3 craptops for presentations or some shit like that and they have mental problems becouse cheapest shit on market is more shitty than they anticipated ;-;
fucking seriously ;-;16 -

My Ryzen CPU got quite hot, and hence also loud, under sustained all-core workloads. The CPU boost doesn't bring that much performance in these workloads (but it does in gaming), so I made two Linux bash scripts.
One does the actual boosting, cpu-boost.sh: https://pastebin.com/K9YShNM6
The other uses Zenity as GUI wrapper so that this can be hooked into the start menu, cpu-boost-gui.sh: https://pastebin.com/X7rhZ8DV
Now I can change it on the fly, even via GUI. Thanks to some sudoers settings (see comments in the first script), I don't even need to enter a password. Obviously, this is only for personal machines, not advisable on servers.
Maybe someone else finds this useful.3 -
I'm writing a devrant like site, so a kind of forum that supports live chat under every article. Login will be just username and password to stay anonymous. Email is optional for password reset. Also it won't have password requirements. Who cares if user uses insecure password. I do like the devrant avatar thing. I will use the ducky generator instead. So everyone on the site is a custom duck. K-SASS prolly never expected his generator to be used anywhere. The requirement of this site is that it scales very well. I have db calls of 0.006s, this is for persistent data only and will be used by all site instances. I expect that it can handle many clients concurrent as long I do not return more than 30 rows or so. Events get handled by a self written pubsub server.
All sounds great and development goes fine. But why is this a rant? Because the same thing as always is biting me, I can't design a site at all. I know how but I don't have any feeling for design at all making me almost incapable of building an attractive site. The only thing I can 'design' is an application in bootstrap or smth. I spend so much time one design while I don't like to do it ironically. But looks of site is almost as important as an good working site. Good working site doesn't get used if looks bad in many casee. This is since the start of my career an issue and it sucks that I appearantly can't deliver a whole site on my own meeting my standards.
My backend work is top notch tho. Btw, this application is not to be an alternative for devrant. I do not think I can attract more users than it already has and I've seen two communities disappearing once because someone decided to make a new one, took half of community with him and both communities died after short while.
End product of this project is a working project, not a live site hosted somewhere. It's pure about mixing mostly self written tech to get the best performance. Reinventing wheel on many levels. I wanted maybe to do the site in C but decided that it's way to much work for the value. I change the site so rapid since I don't have decent plan that python aiohttp is the best choice in amount of writing it yourself and fast. It's very lightweight.
More a story than a rant, sorry29 -
PM tells me to merge (large feature) work that's heavily under WIP.
In that is a performance optimisation he instructed (with an aggressive DM) me to stop looking at even though it's a concern for larger clients that I had to fix before as it's "unnecessary" - thought whatever I'll leave the code as is then
I tell him him the PR is not ready yet, there is still a lot of clean up to and tests to write
Just do it
A ~week later "wow you write really selfish code like look at this"
Shows a wrapper class from the optimisation with 2 properties and getters and setters (and override some of super's properties). I explain to him why it's there, "that should have been a comment". I tell him I write detailed comments as part of my refinment process which he wanted me to stop.
This is after he tried to merge a release branch into main while sneaking in some "corrections" and I pointed out it breaks Dev.1 -
Man I have no idea how my company is running as stable as they do. Every time I peak under the curtain of some piece of machinery I find such bad practices…
Just found out our in house database manager only supports listing all objects in a table, updating objects by first reading each row you need to update and only support “select *” queries.
This is after having to argue with some engineers that using http or grpc when interacting with the new service I’m writing in the none-jvm language is better than writing our own driver for their custom rpc and service discovery system.
But like honestly I’d be mad if these decisions had a visible performance impact on the business, but it somehow doesn’t… this is bizzaro world where all I learned from my 8 years experience as a professional goes out the window…1 -
The ticket system blokes - episode 3
So we always had and have very awful performance with our ticket system. You can't get anything to load in under ~4s normally. Now since it has gotten worse over the last weeks i decided to set aside a few hours to closely watch our SQL server.
After i identified a culprit that was hogging the CPU almost every 2 minutes i looked at other long running queries in the server and found out where exactly the 4s come from.
6 tables from various DBs. Sure, no problem.
Left Outer Join. Sure, why not.
Querying every fucking column in every fucking table explicitly adding up to a whopping 160 columns which they need not even 10% of. We're talking about session IDs, passwords, stock count, IBANs and all that stuff to show the work done on a ticket. Absolutely not.
So i extracted the query and reduced it to the stuff we need and the execution time went from 4 seconds to almost instant.
The funny thing is that their idea of performance optimization is throwing LIMIT around everywhere to get these monstrous queries under control.
So in the next few days I'll have an appointment with their lead programmer. I'm looking forwards to it.
So out of curiosity: does anyone know an SQL builder or toolset that does shit like
SELECT X AS [t0_c0],
SELECT Y AS [t0_c1],
SELECT Z AS [t1_c0],
and so on? I'd like to know how they got to this point.4 -
aagh fuck college subjects. over my last 4 years and 7 sems in college, i must have said this many times : fuck college subjects. But Later i realize that if not anything, they are useful in government/private exams and interviews.
But Human computer Interaction? WHAT THE FUCK IS WRONG WITH THIS SUBJECT???
This has a human in it, a comp in it, and interaction in it: sounds like a cool subject to gain some robotics/ai designing info. But its syllabus, and the info available on the net , is worse than that weird alienoid hentai porn you watched one night( I know you did).
Like, here is a para from the research paper am reading, try to figure out even if its english is correct or not:
============================
Looking back over the history of HCI publications, we can see how our community has broadened intellectually from its original roots in engineering research and, later, cognitive science. The official title of
the central conference in HCI is “Conference on Human Factors in Computing Systems” even though we usually call it “CHI”. Human factors for interaction originated in the desire to evaluate whether pilots
could make error-free use of the increasingly complex control systems of their planes under normal conditions and under conditions of stress. It was, in origin, a-theoretic and entirely pragmatic. The conference and field still reflects these roots not only in its name but also in the occasional use of simple performance metrics.
However, as Grudin (2005) documents, CHI is more dominated by a second wave brought by the cognitive revolution. HCI adopted its own amalgam of cognitive science ideas centrally captured in Card, Moran & Newell (1983), oriented around the idea that human information processing is deeply analogous to computational signal processing, and that the primary computer-human interaction task is enabling communication between the machine and the person. This cognitive-revolution-influenced approach to humans and technology is what we usually think of when we refer to the HCI field, and particularly that represented at the CHI conference. As we will argue below, this central idea has deeply informed the ways our field conceives of design and evaluation.
The value of the space opened up by these two paradigms is undeniable. Yet one consequence of the dominance of these two paradigms is the difficulty of addressing the phenomena that these paradigms mark as marginal.
=============================7 -
unpopular opinion: maybe updates would take under <super long time that's overblown> if you did it more often. Also defrag your standard HDDs like every month (weekly if you really want the performance boost)8

So, I produce a monthly report for our customer service department each month, and this report includes various statistics related to our company's support performance. Two of the included statistics are the "Average Speed of Answer" (ASA for short) and the "Abandoned Call percentage" (ABD % for short) that are derived from client calls to support.
The formulae for these values are:
- ASA = time in seconds all calls that were answered spent waiting to be answered divided by the number of answered calls - displayed as hh:mm:ss
- ABD % = number of abandoned calls minus those that were abandoned in under 10 seconds (referred to as "short abandoned") divided by the sum of total calls that were offered minus the sum of short abandons & transfers
These statistics are also included in a daily version of the same report that all Customer Service leadership personnel have access to.
Now, every single fucking month the same Sr. Manager always has some kind of "discrepancy" with the monthly report that ALWAYS boils down to his dumbass trying to average shit on the daily Excel reports for that month and it being different than what the monthly report is showing. Now, these reports ONLY display the calculated value for any calculated fields mind you - not the raw values of the DB fields used in said calculations.
This month I have to tell this shit-for-brains that you can't just take an average of ASA & ABD % from the Daily's and compare them to the Monthly numbers because their calculated fucking fields!!!
Come to think of it, this has been his issue for like the past 5 months, and I seriously can't fix stupid!
Sometimes I just wanna reply to his snarky ass, corporate bullshit emails like, "BRUH!, The only motherfucking discrepancy I can locate is your IQ and your fucking title - that shit don't correlate homie! Need to take that ass back to High School statistics or something!"
But I digress...
TL;DR
I have to deal with a Sr. Manager who doesn't fucking realize you can't average a calculated field from a daily report and think it's gonna match up with the monthly report. I believe he is borderline retarded, and I often wonder how he got the "Sr." In his title let alone "Manager".
Oh wait, this is corporate America - you just gotta kiss the most ass... never mind.4 -
Windows XP was just right. A perfect balance of performance and functionality.
Everything less complex feels too impractical, everything more complex feels too uncontrollable.
When using XP, I was confident I could get the job done, yet I knew what every process in the task manager did. It’s not the case with 7, let alone 10/11. I don’t know what happens under the hood there at all. Maybe custom Linux distros qualify too, but they’re unapproachable by laypeople. You have to be a geek to use them effectively.
Windows XP struck just the right balance between functionality, simplicity and compatibility. Too bad the era is gone in favor of opaque surveillance.8 -
Can someone tell me why C++ and python are so widely used in the AI department? I kind of understand… you want maximum performance (plus GPU) with C++ or easy logic with Python but still, it seems like other languages would still have there benefits in AI. It just doesn't make sense to me, why isnt it like every single other part of computer science where everyone under 22 thinks "now this is what JavaScript was made for!" (I mean js is used so much in other parts of cs, why not AI). Am I missing something? Maybe the resources are missing for AI in other languages? Can someone please expand12

If you know any good windows laptop in this price range please let me know :)9 -
So i'm visiting the JavaScript bubble every now and then when i'm writing on the userscript i develop to fix bugs in our ticketing system or fix some clients website they negelected. Every time i'm searching for answers to the weird problems that inevitably turn up i have to filter out all the threads that derail with the classic 'google jQuery basic arithmetic plugin' craziness to find an actual vanilla solution to my problem.
All the time i wonder why on earth people put up with this framework hell. This is part serious question and part rant but seriously, how did we come to this? With all that jQuery, React, Node, whatever stuff i'm kinda losing the overview over what's even todays standard. I always try to keep my code as vanilla as possible without using external libraries. But it seems the entire web development industry is heading the completly other way. I tried to look into a few frameworks but i never really see the appeal. Just now i looked up react native because the last 20 rants talked about it and immediately noped out because they fucking create a DOM in js, why the fuck would you do this?!
Worst thing about this framework shithole is that some frameworks are beeing pulled into the mix for very weird and unnecessary reasons. Best example is a charts library i recently used to visualize a database of temperatures that was completely written in native js but pulled jQuery in for the equivalent of window.addEventListener('load',function(stuff)) and i was furious. I rewrote the code and could throw out the jQuery dependency with no problem. What the fuck is wrong with people?
Alright since you made it here: I'm not trying to throw any of you under the bus for using frameworks. I just fail to understand why you would use these. To each their own and unless your site has the performance of the ticketing system i use at work that takes like 15 seconds to load one fucking page i won't complain at all. But pull in a framework just to do a task you can easily do in native js in remotely the same timeframe you are on my list.2 -
I will not miss you bitch. See screenshot. I received new hardware. I will use a laptop with good specs as server. My dad bought it from his previous employer because he went for retirement. It has an ultrabook-grade 11th gen processor and he only bought it for 350,- euro. His former employer was a school, they don't give a fuck about money like a commercial company would do in such case. It's originally bought with tax money anyway.
https://llm.molodetz.nl is currently online but not for long, i hope to have smth running at end of the weekend. Probably a 7b model. I have plans with it that require some performance so I won't use the heavy ones.
Retoor1b currently is 0.5b or 1.5b. I forgot. The models with lower parameter count are a bit more naive and trainable like a kid. They're also not very biased yet. So, that will be my main new challenge. How to make a chat bot unethically human. No political correctness under this roof.
Would be nice if i could make it a bit like bratgpt. Sounds like a joke, but that model is expensive as fuck. You'll be shocked. But i would like to implement some sarcasm in it. A bit unpredictable. But normally such configuration escalates into very weird behavior.
My 'server' has a freaking 4K screen and i'm working on a decade old laptop. But seriously, the keyboard of the new one sucks. Nothing beats a x270. * tik tik tik * rakketakketak *. My previous x270 missed four keys. The three x270's i had, all had familiar experience but still different. The other two would never lose a key I guess. I configured the new 'server' that it safes battery, configured for mostly on AC.
I'm living on limited amount of cash (and will work again when i will run out). That's why i normally don't spend money myself on such things. So i'm now very happy. Fuck, this was about to be rant about how much my AI sucks but it ended in happy stuff. Oh well...
If you're still reading, you're the best!
Edit:
Images uploading broke again. Here is link: https://devrant.molodetz.nl/llm.png10 -
So I literally added a "slow mode" switch to the application. A line in the config which is directly passed to the Thread.sleep()
Imagine that, when under heavy load, performance increased.1 -
So I was reverse proxying this new Social network app's API and saw an interesting endpoint
It was a websocket relaying what each live user's doing every 2.5s, to power the "xyz typing" under a post, or a simple online/idle.
The app's "live posts" ie most-recently created posts was also powered by it since they knew each user's state (instead of a periodic API call)
The performance is good even tho it's a new company + enough users
but now im curious how prevelant state-management is using such websockets .-.
if not taxing, i might move any API call which ive to ping every 15s or less to a live WS4 -
The Odyssey of the Tenacious Tester:
Once upon a time in the digital kingdom of Binaryburg, there lived a diligent software tester named Alice. Alice was on a mission to ensure the flawless functionality of the kingdom's latest creation – the Grand Software Citadel.
The Grand Software Citadel was a marvel, built by the brilliant developers of Binaryburg to serve as the backbone of all digital endeavors. However, with great complexity came an even greater need for meticulous testing.
Alice, armed with her trusty testing toolkit, embarked on a journey through the intricate corridors of the Citadel. Her first challenge was the Maze of Edge Cases, where unexpected scenarios lurked at every turn. With a keen eye and a knack for uncovering hidden bugs, Alice navigated the maze, leaving no corner untested.
As she progressed, Alice encountered the Chamber of Compatibility, a place where the Citadel's code had to dance harmoniously with various browsers and devices. With each compatibility test, she waltzed through the intricacies of cross-browser compatibility, ensuring that the Citadel would shine on every screen.
But the true test awaited Alice in the Abyss of Load and Performance. Here, the Citadel's resilience was put to the test under the weight of simulated user hordes. Alice, undeterred by the mounting pressure, unleashed her army of virtual users upon the software, monitoring performance metrics like a hawk.
In the end, after days and nights of relentless testing, Alice emerged victorious. The Grand Software Citadel stood strong, its code fortified against the perils of bugs and glitches.
To honor her dedication, the software gods bestowed upon Alice the coveted title of Bug Slayer and a badge of distinction for her testing prowess. The testing community of Binaryburg celebrated her success, and her story became a legend shared around digital campfires.
And so, dear software testers, let the tale of Alice inspire you in your testing quests. May your test cases be thorough, your bug reports clear, and your software resilient against the challenges of the digital realm.
In the world of software testing, every diligent tester is a hero in their own right, ensuring that the digital kingdoms stand tall and bug-free. -
I got a long weekend. I decided to see what React has been up to these days.
I happen to learn more about Suspense that now it allows f**king data fetching with relay.
I decided to give it a try . First time I am actually inclined towards trying out relay just so I can see what the f**king fuss about `Suspense` is all about.
Honestly the API is much better than what it looks like .
However what the fuck is this fucking relay. They have a page in their doc called glossary and most of the sections says TODO .
I wanted to see how the fuck data driven code splitting works . Due to the lack of proper documentation about it I could not get it right for two days . I stumbled upon couple of docs / blogs / github issues about it and then finally managed to get it working .
Well the end result wasn't as cool as I thought it would. The fucking API's to achieve this needless method of code splitting is insane
There are lot of better ways to achieve this with Suspense and the API relay offers is so shitty and not fucking type safe.
Now today I wanna learn more about the directives relay offers and there is no fucking documentation about them except for a fucking bold `TODO` explanation under the sections.
If relay developers thinks that they are fucking wizards and talk all about improving fucking performance . Please don't fucking over engineer API's and make it un un maintainable for the consumers of the library
Wow this feels good . first Day in rant and I m feeling great4 -
Up until now, I never had any breaking updates on Linux on my laptop, Except for Nvidia drivers stopping. It would switch to noveau. Even my cobbled together hack of Broadcom Bluetooth solution worked without even having to touch it. Well, I still don't have problems with core Linux but add gnome to the issue mix today. Surprisingly, Nvidia drivers for the first time Nvidia drivers upgraded (to 340) and I didn't had to do anything for it to work. Gnome deprecated synaptics driver support and now uses libinput implementation for it. Well Ubuntu Gnome updater won't clean the configuration and I had to remove the driver and clean config myself. Nothing too much, i have to deal with these stuff on my arch installation but Ubuntu has been "it works fine. No need to interfere" thing for me. It works fine on Wayland (it always used libinput on Wayland a if I am correct) but nvidia drivers doesn't support Wayland. And then since the update gnome has been disabling some of my extensions at random. All on X. I have no problems with Wayland except for Nvidia fucking drivers. All that said, its still better than windows where I lost fucking network connectivity during something important. And the trackpad drivers on Linux are somehow much better than anything I have used on windows. (that or Sony made fucking great trackpads and nobody noticed). Here's to hoping Nvidia starts supporting drawing on Wayland and I can ditch X completely. I have seen visible improvements in performance under load and slight decrease in battery usage with Wayland.8

Does any of you have the compulsion to micro-optimize every bit of code that you write? How do you deal with it?
I'm not just talking about algorithmic optimizations, but the real nitty gritty stuff. I'm talking about using bit fiddling to avoid if statements where speculative processors might make mispredictions. Anything that might make a program compile to fewer machine instructions or avoid extra stack frame overhead.
This all started a year ago when I took a systems programming course at my university, and started learning C and C++. But I find myself doing this in the wrong places. Who cares if this trivial program that I wrote runs in 1.2 or 0.6 seconds? My future employers won't care if my code is 10% more efficient when it takes four times as long to write.
It's gotten to the point that I can't bring myself to use languages like Python because I don't know how it's implemented under the hood and can't predict how the different ways I could write a function will affect performance. How do I bring myself to trust that the compilers (or interpreters) and the programmers that wrote them will be sufficiently optimal, and just move on? 😩4 -
Why are non-technical people put in charge of technical people? I get there's a stereotype that programmers aren't good with people, but that's not really my experience. How can I fail to achieve expectations when you don't outline any? How is "I didn't see you run enough scripts" a valid criticism when they're run locally from my machine with no record being created? Especially when those scripts are only for very specific processes I generally don't deal with? Seriously I was on the team less than 5 months come my yearly review and I'm already under-performing? I can't even switch teams because in-house recruiters always request the last performance review and mine sucks thanks to that asshole. Nevermind the one before that I excelled, but different role doesn't matter I guess. Some days I'm so tempted to cash out that 401k and just hope I find a better job within a year. Anyone have advice on dealing with this shit?5

Anyone interested to see mine and my wife’s culture & technology crossover performance/arts/music project?
The name is UDAGANuniverse. Udagan in Sakha (northeast Siberia) language toughly translates to ‘she shaman’. I met my wife while she was touring in Europe with a traditional Sakha group (I was touring Celtic trad music that time).
The project is incorporating all our interests, artforms and professional skills under a shamanistic aesthetic. Functional Programming, Live Coding and Machine Learning play a big part in my input and live performance role.
First episode of our newly launched podcast:
https://udaganuniverse.com/news/...
My personal articles — arts based and touching on functional programming + category theory:
https://udaganuniverse.com/music
I’ll be posting new articles more specifically on Coding and ML in performance in the next weeks.
If you’d like to see a little personal backstory (how we came to fuse performance with code/ML) check out this rant here:
https://devrant.com/rants/1279742/...
Hope that you enjoy and please let us know any comments or feedback!3 -
rent / question (there is a question at the end and I'd appreciate your opinion)
8 months ago, I agreed to help a not too distant relative of mine to do his master thesis at the company where I work. He was supposed to build something really MVP, but useful for us and I'd help him get some scientific questions out of it, and provide him with (computing) resources to test his theories / implementations under simulated and much heavier load.
Since then, he didn't get done anything even remotely useful, always just stuck on very rudimentary issues, claimed things are almost ready, I wrote a quick smoke test to prove that the whole application blows up when you touch it, in short - a disaster and went over to radio silence.
In the meanwhile, we didn't need it anymore, so 1.5 months ago, I got in touch with him again, with an even more technical proposal, something, at least I'd think, that's even cooler to do. He asked me some question about hypothetical load, the system should be able to handle eventually, to come up with alternative implementations to compare them against each other. He said that his exam period is going to be over soon and he'll get back to me with some initial version.
2 weeks ago, I got back in touch with him, trying to urge him, to get finally started and get something done. If he'd actually sit down and do it during the holidays as a "full time job", he'd be probably done in 2 weeks. Last week, he came back to me and said he has an initial PR ready to review.
I was excited about it, but basically froze when I realized what he did. He deleted all his previous work - some infrastructure stuff which took us basically 3 months of back and forth to get running - and as far as I could see, all the new code were only auto generated clients based on a swagger specification. In short - I could do it in less then an hour. If you really have no idea what you're doing, it might take you half a day, but definitely nowhere near to a week.
His brother, which a good friend of mine, thinks I'm being too hard on him. His argument was, that it's too hard, and he has to do it in C#, but he only knows Java (I gave him access to some of our repositories to copy paste code together, he didn't need to invent anything. I also prefer C# but wrote my master thesis in Java) Personally, I'm just pissed because he promises stuff that he never does. I totally understand him - I was like that as a student as well, I guess karma is a ... but still, he's wasting my time.
Right now I'm thinking how to get out of this, without having even more time wasted. I doubt he'd ever deliver anything useful. He got plenty of input from me about what he could consider for his scientific question, how to measure performance, ... He can keep his credentials to access our test environment with the test data, but I won't give him access to any additional computing resources, to compare how his solutions might scale on our company's cost. (mainly it's not the money, but I'd have to provide that stuff, and probably help him set it up)
does it sound like a fair deal (saying, I'm done with you. You can finish your topic on your own, but don't expect any help from me)? or am I being a dick about it and too demanding?1 -
I started reading this rant ( https://devrant.com/rants/2449971/... ) by @ddit because when I started reading it I could relate to it, but the further he explained, the lesser relatable it got.
( I started typing this as a comment and now I'm posting this as a rant because I have a very big opinion that wouldn't fit into the character limit for a comment )
I've been thinking about the same problem myself recently but I have very different opinion from yours.
I'm a hard-core linux fan boy - GUI or no GUI ( my opinion might be biased to some extent ). Windows is just shit! It's useless for anything. It's for n00bs. And it's only recently that it even started getting close to power usage.
Windows is good at gaming only because it was the first platform to support gaming outside of video game consoles. Just like it got all of the share of 'computer' viruses ( seesh, you have to be explicit about viruses these days ) because it was the most widely used OS. I think if MacOS invested enough in it, it could easily outperform Windows in terms of gaming performance. They've got both the hardware and the software under their control. It's just that they prefer to focus on 'professionals' rather than gamers.
I agree that the linux GUI world is not that great ( but I think it's slowly getting better ). The non-GUI world compensates for that limitation.
I'm a terminal freak. I use the TTY ( console mode, not a VTE ) even when I have a GUI running ( only for web browsing because TUI browsers can't handle javascript well and we all know what the web is made of today - no more hacking with CSS to do your bidding )
I've been thinking of getting a Mac to do all the basic things that you'd want to do on the internet.
My list :
linux - everything ( hacking power user style )
macOS - normal use ( browsing, streaming, social media, etc )
windows - none actually, but I'll give in for gaming because most games are only supported on Windows.
Phew, I needed another 750-1500 characters to finish my reply.16 -
At what point are you an expert in C++?
Herb Sutter's talk tilted "Back to Basics" (available on YouTube) contains the message "it's easy to forget that you're an expert" in the context of writing code that utilizes the latest complicated features of a language to squeeze out the last drop of performance.
So what makes someone an expert? Is it just writing production code? Is it groking the entire panel presented by a standards committee member? Is it contributing to the STL? Is it when you can write your own compiler while blindfolded and juggling rubber duckies in under 60 seconds?
What makes a person an expert in any language, for that matter?5 -
Oh let the rant time begin…
So previous post I mentioned about this dev who has resigned and how I was going to see about a Snr. position.
Management is now scrambling to figure out what to do as this dev managed all the migration to AWS etc, I know servers but haven’t got too much familiarity with AWS.
Anyways so I finally get a 1:1 with my new line manager. I ask about the position and he says they don’t know what there going to do yet. Hire a new dev in India to offset and with the same knowledge even though the guy leaving is in the U.K. Bad idea as the servers are in the U.K. so if we get downtime or the server crashes we have no one in the U.K. to reset or access to the servers. India are very cagey who gets access which is annoying to say the least even though us (three devs) in the U.K. are the principal engineering team so there looking at all options.
Anyways we have a back and fourth, we discuss some of the plans for the app, some of which we are nowhere near ready to even conceptualise as the app in its current state sucks, (ruby 2.2.6 and rails 5 but not really). Needs major refactoring and rewrite, one thing they want to do is multi tendency which again given the state is laughable.
So, as my manager is speaking my head is screaming being like “this is just going to be a massive disaster”. Then we go onto that he’s seeing what everyone’s strengths are etc. And then we get onto the upgrade and that he wants me to work on it.
Yes.. the upgrade I’ve been trying to do for the past 4+ months but I keep getting told to stop and getting pushed backed.
I’ve been told we have devOps looking into restructuring the app, not possible as how the app is written, we have India trying to multi tenant again disaster incoming as they’ll end up rushing it. Legal are going to have a field day. Every time I say the issues are the fundamentals with the app, here’s how we can sort it. In one ear out the other basically there patching the ship even though it’s still leaking.
I have so many ideas, and things I can do to improve the app and get it back to not only working order, fix the performance issues, data issues and everything else. Brick wall.
So rants ensue where I basically say I would love to do the upgrade but management gives me no time in the roadmap (we have no say in planning). At this point I’m just speaking to a brick wall.
After the meeting I have a chat with the BAs, we all have the same issues so honestly it sucks we end up ranting to each other for an hour.
I’m being under-utilised, being told do this, do that even though I’ve had two stabs but told to stop and pushed back, I know what benefits I can bring to the app with a refactoring, ideas and how to properly lead the team because honestly we’re working on an old legacy app, and management are clueless and there priorities are all wrong, the company is getting frustrated and it’s a sinking ship. They would rather patch issues without solving them and everything I say goes in one ear and out the other.
Frustrating is not the word.1 -
God damn it, Gatling. Why didn't you put your fucking command line argument passing at the front of your docs instead of being buried under 'cookbook'? It's not a fucking recipe! it's core mother fucking functionality! "how do I run this command-line utility from the command-line by script?". "I don't know, maybe I should check the fucking cookbook since apparently it's not basic functionality that LITERALLY everyone using the fucking product will need!
So now I have to go back and parameterize one of the sims I've built AFTER I've mimicked our entire performance test matrix! FUCK! -
