So I named my daughter "io"
everyone calls her by the name and then we register her on our local gov't to get birth certificate.
AND THEN THESE FUCKED FACED FUCKERS! dont accept my daughter's name because of this STUPID SYSTEM OF THEIRS!
because "io" is too short for first name field to accept. Its like the devs become the law and just set their own limit.
It pisses me off. our law didn't say `len(firstName) > 2` and we can't use paper anymore as alternative.
I really want to punch the fucker in neck. sorry40 -
Hi everyone,
We're currently experiencing major issues with the devrant.io domain due to another outage/problem with .io domains themselves. More info here: https://news.ycombinator.com/item/...
The issue is also being reported on twitter.
If you receive a host not found, connection error, etc. connecting to devRant, this is why. We'll keep you updated and in the future we will probably be switching away from .io at least for our API.
Thanks for the patience.20 -
Anyone looking for something interesting to do???
Step 1) understand how basic circuitry works on a bread board nothing too fancy. ( Implement NAND, AND, ADDER, SUBTRACTOR)
Step 2) learn about microprocessors and how OS works
Step 3) learn assembly
Step 4)write a basic assembler and understand how loaders and linkers works !
Step 5) write a kernel with very basic features like memory management and process management and some drivers for IO
Step 5) write an emulator for some simple systems .! ex chip-8.
Step 6) read about compiler theory and automata
Step 7) write a basic Python interpreter that compiles (not interpreter) to native assembly.
Step 8) implement TCP stack .
Step 9) learn as much as u can about complexity measurement ), data structures and algorithms using C or C++ it's very important ( familiarity with pointers and thus computer memory )
Step 10) learn any high level language of choice like Python or Ruby.
Step 11) stop debating over tabs vs spaces , emacs vs vim , angular vs vue, php vs Python , OOps vs procedular vs functional ( just know about all of them and when to use but don't fucking debate over which one is superior )..
Step 12) live happily and be healthy.30 -
Techy name? Check.
Word which ends with "er" but scrap the E? Check.

Want to Google io earlier this month and a senior director at Google game a presentation and used a chrome dino for a demo and after I found him on LinkedIn and asked her m where I could buy one and he asked for my address and sent me one for free. Idc what any of you say Google is really cool for doing this.

So just recently my school blocked the following for unknown reasons websites
Github
Gitlab
Amazons aws
stack exchange
Bitbucket
Heroku
The hacker news
DuckDuckGo
The Debian package repositories yea all of em
And all domains that end in .io
Now some of you out there are probably just saying "well just use a vpn" the answer to that is I can't the only device I have a locked down school iPad can't install apps cannot delete apps cannot change vpn or proxy setting's I cannot use Safari private tab they have google safe search restricted to "on" they even have "safari restricted mode which lets safari choose what it wants to block" and even when I'm on my home wifi it's s still blocked as they use Cisco security connector THIS IS HELL
Also this is my first post :)30 -
You is not gonna beliebers what just happened lol
So a couple weeks ago I earned a stress ball (300+ ++'s) I sent an email about it but never got a reply, so I decided to just forget about it. But then I just ranted (lastnight) about how its so hard to get a stressball. So I basically just said "fuck it i'll buy one". Then some dude comes along and is like "omg not until he shows us the bought one" so I'm like CHALLENGE ACCEPTED and buy one...
Then I get an email confirmation from devrant store confirming my order for the bought stressball. And I notive that my spam folder has unread messages in it. i look inside the spam folder and what do I see?...
I see dfox replying to my free stressball request weeks ago lol. So yay, now I gets the 3 balls (or two - depending) lol omg, so many balls.

You know what I realized we should always say no for demo driven application development.
We should always ask for enough time do a proper development and if its not enough, shouldn’t write a single line.
Because once we deliver a working demo. Its release ready for them because its FUCKING WORKING..
And trying to explain why this is just a demo and cant be put to production is even bigger pain in the ass than saying no in the beginning.

When you just finished watching Google IO and they presented lots of super cool machine learning powered stuff...
... And suddenly, what you've been working on just few hours before, feels like:
"Yay! Finally this button is changing the color of this text!"1 -
What is it with clients who have never even seen a single line of code in their entire lives telling me how long they believe a certain change request should take to code.
I mean, what if I told you that your "seemingly simple enough" change needed an update to 36 class files, 9 oracle stored procedures AND several database schema changes. Also, who the fuck is going to perform a regression test to make sure I didn't break anything? Your Uncle Bob??6 -
For a week+ I've been listening to a senior dev ("Bob") continually make fun of another not-quite-a-senior dev ("Tom") over a performance bug in his code. "If he did it right the first time...", "Tom refuses to write tests...that's his problem", "I would have wrote the code correctly ..." all kinds of passive-aggressive put downs. Bob then brags how without him helping Tom, the application would have been a failure (really building himself up).
Bob is out of town and Tom asked me a question about logging performance data in his code. I look and see Bob has done nothing..nothing at all to help Tom. Tom wrote his own JSON and XML parser (data is coming from two different sources) and all kinds of IO stream plumbing code.
I use Visual Studio's feature create classes from JSON/XML, used the XML Serialzier and Newtonsoft.Json to handling the conversion plumbing.
With several hundred of lines gone (down to one line each for the XML/JSON-> object), I wrote unit tests around the business transaction, integration test for the service and database access. Maybe couple of hours worth of work.
I'm 100% sure Bob knew Tom was going in a bad direction (maybe even pushing him that direction), just to swoop in and "save the day" in front of Tom's manager at some future point in time.
This morning's standup ..
Boss: "You're helping Tom since Bob is on vacation? What are you helping with?"
Me: "I refactored the JSON and XML data access, wrote initial unit and integration tests. Tom will have to verify, but I believe any performance problem will now be isolated to the database integration. The problem Bob was talking about on Monday is gone. I thought spending time helping Tom was better than making fun of him."
<couple seconds of silence>
Boss:"Yea...want to let you know, I really, really appreciate that."
Bob, put people first, everyone wins.11 -

What's with the 4 pixel wide scrollbars on some desktop software these days? Does nobody care about accessibility anymore?
No seriously.
Fuck you.
And why the fuck does open source software seem to be the main culprit - as usual.
And tutorials telling us to add an extra blank line to our source code because fucking Linux distros decide to put an overlay horizontal scrollbar just over the top of where the last visible line in an editor appears.8 -

Hello everyone 👋
I see people blaming the developers when you see a crappy software product , saying that they have done a bad job.
But even it could be true also it could be the product managers who didn’t give enough time todo what needs to be done or project scope is too big for the persons knowledge.
I’ve worked in a company where deadlines were so tight I didn’t have enough time to proper UI and Testing. I used to be only developer who has someone experience and I had to train the interns as well. I am also to blame to joining such company but in desperate times takes desperate measures.
And now when i’m leaving the company and I have spend 2 years of my life for apps that I’m not proud of.
Just rant. Please feel free to give ur thoughts2 -
Sister of a friend of mine fucked up her Mac, her Dad, they called me to fix it.

So I was wondering, what is you guys' 'goal' in the long run? What do you really want to be able to do or what do you really want to achieve in 5 to 10 years? Are you working primarily for an income or are there more prominent reasons for doing what you do?
I'm in my last years of university and have a job at a software development company, not because I need the money but because of all the amazing technologies I come in touch with and the amazing things I learn, mostly about servers and devops tools.
I currently have 2 goals in mind: Creating an .io game together with a frontend developer and setting up a kubernetes cluster and using it. I personally consider kubernetes an end-game thing when it comes to running apps and am experimenting with it on three servers that I got from school.
So I was wondering, what ahout you? 😀27 -
Wanna hear a story? The consultancy firm I work for has been hired to work on a WPF project for a big Fashion Industry giant.
We are talking of their most important project yet, the ones the "buyers" use to order them their products globally, for each of the retail stores this Fashion giant has around the world. Do you want to know what I found? Wel, come my sweet summer child.
DB: not even a single foreign key. Impossibile to understand without any priopr working experience on the application. Six "quantity" tables to keep aligned with values that will dictate the quantities to be sent to production (we are talking SKUs here: shoes, bags..)
BE: autogenerated controllers using T4 templates. Inputs directly serialized in headers. Async logging (i.e. await Logger.Error(ex)). Entities returned as response to the front end, no DTOs whatsoever.
WPF: riddled with code behind and third party components (dev express) and Business Logic that should belong to the Business Layer. No real api client, just a highly customized "Rest Helper". No error reporting or dealing with exceptions. Multiple endpoints call to get data that would be combined into one single model which happens to be the one needed by the UI. No save function: a timer checks the components for changes and autosaves them every x seconds. Saving for the most critical part occurring when switching cells or rows, often resulting in race conditions at DB level.
What do you think of this piece of shit?6 -

Hmmm, this feature that I added seems to make the whole process 50% longer. I need to optimize something. Let's see now...
Yeah, make that a shared resource and parallelize IO to leverage the multi-core architecture. Hash map for this, binary tree for that. This thing that gets called a million times can be written easily without a regexp. That thing can be rewritten in Rust as it's too demanding.
There! Works! And it's also a lot cleaner. Nice!
How's the performance doing? 70% longer.

I'm not much a fan of JavaScript. In fact, I am not very fond of any dynamic language, but JavaScript is one of my least favorites.
But this isn't about that. I use NodeJS for all of my web serving. Why would I do that? Am I a masochist? Yes.
But this isn't about that. I use NodeJS because having the same language on client and server side is something that web has never really seen before, not in this scale. Something I really really love with NodeJS is socket connections. There's no JSON parsing, no annoying conversion of data types. You can get network data and use it AS IS. If you transmit over socket using JSON, as soon as that data arrives on the server, it is available to use. It gets me so hard.
JavaScript is built to be single-threaded, and this is rooted deep into the language. NodeJS knows this isn't gonna work. And while there's still no way to multi-thread, they still try their best and allow certain operations (Usually IO) to run async as if you were using ajax.
With modern versions of the language, the server and client side can share scripts! With the inclusion of the import keyword, for the first time I have ever seen, client and server can use the same fucking code. That is mindblowing.
Syntax is still fluffy and data types are still mushy but the ability to use the same language on both sides is respectable. Can't wait for WebASM to go mainstream and open this opportunity up to more languages!10 -

I found this on a wiki with Haskell Humor... it's interesting...
How to Shoot Your Self in the Foot With Haskell: Putting the unsafe in unsafePerformIO!
You shoot the gun, but the bullet gets trapped in the IO monad.
Couldn't match expected type 'Deer' against inferred type 'Foot'.
While compiling your program the compiler produces a type error long enough to overflow a kernel buffer, overwrite the trigger control register and shoot you in the foot.
After trying to decipher the type errors from the compiler, your head explodes.
After you've finally found a way to circumvent the type system and shoot yourself in the foot, Oleg appears out of nothing and shoots you in the foot for coming up with it before him.
You shoot the gun but nothing happens (Haskell is pure, after all).
Your foot is fine, until you try to walk on it, at which point it becomes mangled.
You have a shootFoot function which you've proven correct. QuickCheck validates it for arbitrary you-like values. It will be evaluated only when you end up at the hospital. You hope this doesn't come to pass, as it actually returns a bullet-ridden copy of yourself and you don't want to be garbage-collected.
foreign import ccall "shootparts.h shootfoot" shoot_foot :: Gun -> Programmer -> IO ()
shootSelfInFoot = unsafePerformIO . shoot . foot $ self -- Shoot self in foot 0 or more times depending on evaluation order
No instance for (Target Foot)
arising from use of `shoot' at SelfInflictedInjury.hs:1:0
Possible fix: add an instance declaration for (Target Foot)
In the expression: shoot foot
You go to shoot yourself in the foot but the bullet is in the ST monad and the gun is in the IO monad, so you can't.
You ask Haskell to shoot you in the foot but by the rules of lazy evaluation you don't need the result yet so it doesn't happen.
You decide to shoot yourself in the foot but get distracted devising a ballistics algebra and wondering if you can do the calculations in the type system.
You want to shoot yourself in the foot but realize there is no Gun datatype so use Arrows instead.
You shoot in the direction of your foot, but since you are inside the STM monad you can just retry until you figure out what to do.
You shoot yourself in the foot, but you are perfectly fine as long you just don't evaluate the foot.
You shoot yourself in the foot, but nothing happens unless you start walking.
Don't forget about memory consumption! If you don't look, the bullet causes heap overflow. If you look, the bullet causes stack overflow.
You *appear* to have deliberately shot yourself in the foot, and yet your program actually runs perfectly OK due to lazy evaluation. (So long as you remember to not look at your foot...)
You aim the gun at your foot, pull the trigger and remove the clip. When you look at your undamaged foot, the hammer clicks on an empty barrel.1 -

A few weeks ago, I was kept up until the wee hours of the morning trying to figure out how in the hell the Monty Hall problem works. After finally getting it (I'm slow, okay?), I decided to write a program to run simulations of it.
First incarnation of program took user input. User enters what door they choose (1, 2, or 3), then is told what door Monty opens, then given the decision of staying with the door they originally chose or switching, then informed how that worked out for them.
Second incarnation of program ran on a loop. At the start of each loop, a random door is picked for the user guess. Then the door Monty opens is calculated from the remaining doors (excludes user guess and prize door). Then user switches doors (choosing the door that was not their original door or the door Monty opened). At the end of each loop, if the door they switched to was the prize door, it would increment a win counter, else increment a loss counter. After running the loop 1000000000 times, it printed to console `You always switched doors, resulting in ${wins} wins and ${losses} losses`.
THEN I decided to write a variation to run a while loop on the outside of the loop to increase the number of total doors until the point where the decision to switch doors hurt more often than it helped. At this point, I decided to incorporate file I/O and write to a file rather than a console. And that was neat!
And then I decided it would be cool to go back to the three door variation, printing on each loop the original door, the door Monty opened, the door that was switched too, the result of the switch (win or lose) and what the prize door was.
But for the life of me, I couldn't seem to get the file to write properly. It would, like, always crash my terminal. I tried open + append, I tried append. I tried createWriteStream. Still just failure.
And then I changed it to an appendFileSync and happened to look at one of the files that I was writing to. "Huh, over a gig seems a lot."
"Well, how much are you writing each loop? Did you forget to keep in mind how many bytes that would be?"
TLDR: If you're going to write a program that's going to write data to a file on a loop, you might want to figure out how much it's going to end up writing .... before trying to run it. And running a loop 1000000000 times may be a little excessive.

Lua is one of the stupidest languages to ever exist.
Oh, the language is easy to learn? The syntax is friendly? There's only like negative 10 functions you ever need to know? Everything is a table?
EVERYTHING IS A TABLE?! WTF CARES? WHAT ABOUT NIL?!
The arrogance this language has is extraordinary, literally. No lang, except Lua, imposes such an opinionated dichotomy. Everything is a fucking table, or, it's nil. -- That's so fucking stupid.
And look, I get it, this lang (oh sorry, scripting language (?)) CAN be good and fun and whatever... the moment you start to do IO is the literal end of days.
Everything is nil. Except, if it's defined... then it's not nil. -- OK. That sounds sensible/reasonable enough. -- What if it's not defined? You get nil. What if it's not the right data? You get nil. Do I get errors/exceptions or whatever? No, absolutely not, you get nil... unless the application you're using with Lua with has a lib that handles that.
There are so many more issues I have with this lang, but honestly... Am I fucking missing something? Is this lang like actually super dooper awesome and I'm missing something? -- I can't not look at this language as just dumb and arrogant. -- It's literally a language where you have to manage and remember ALL conceivable state at ALL times.11 -
Idiot mode: on
It's bad when you realize you are the most idotic person you know. I just bought a wifi card replacement for my laptop only to find out that one of the screws on its back was completely unscrewable. I foolishly decided to force my way through by forcing the plastic. I tought I got away with it as I only damaged a plastic support tighten to the laptop base but now, my laptop screen isn't showing anything.
When I first booted it up after this, it was working, but it started showing troubling signs shortly after. Now, all I can get out of it is a completely black screen, no backlight at all.
What should I do? 😥9 -
Making a Snake game. Let me explain.. I had just "finished"(We all know there is no finishing side projects) my first big, at least for me, project. An io game called torpedoed.fun [http://torpedoed.fun]. And yes, it is a desktop only, and also yes, it is not that fun of a game. Torpedoed.fun taught me a lot about developing such as how to debug effectively, backend communication, how to host a website, planning, and much more. After learning all this from torpedoed.fun, I decided to start a new project, a simple clone of the classic Snake game. I, to my surprise, was able to immediately think of several ways of implementing various parts of the game. I developed the entire game in the span of a few hours with hardly any problems! This experience of developing without constantly debugging every line of code felt amazing. If I wasn't addicted to programming before that Snake game, I was afterwards!

ME: *runs a load test for the umpteenth time*
RDS DB: *is slow af: HI contentions*
ME: "dear AWS support, I see the RDS has troubles writing to disk as THIS db exhibits 10x higher W latencies than THAT OTHER db we have. Both are identical, apps are identical."
AWS: "Hello, I hope you have a good day. After the investigation that took us almost 2 weeks, we can confirm that there are 10x higher IO latencies to disks: [CloudWatch link]. We also see a high load average during your tests.
We recommend investigating the high load average and tuning your queries along with the database.
I hope this helps, good day."

I recently saw someone complain because the name registrar would not name their daughter “is” because of their system (https://devrant.com/rants/1154582/...).
I have something to add.
Where I am from (India), local registrars intentionally misspell your name on the papers because than they can charge to a fee to fix it.
That’s why I hate India, too much bargaining for everything. This has happened twice in my family and both times we have refused to pay them.3 -

One of the largest companies on the continent. Uses Oracle on AWS RDS with the beefiest resources available. It comes to the point where lowering the number of CPUs boosts the DB performance up (concurrency). Point is - Oracle is sweating hard during our tests. You can almost feel the smell of those hot ICs on AWS servers.
And then someone at higher levels, while sitting on a pooper, has a great idea: "I know! Let's migrate to Aurora! They say it's so much faster than anything there is!"
*migration starts*
Tests after migration: the database on the largest instance possible shits itself at 10% of the previous load: the CPU% is maxed out (sy:60%,us:40%), IO is far, far from hitting the limits.
Is it really possible Aurora will cope with the load better than Oracle? Frankly, I haven't seen any database perform better than Oracle yet. Not sure if it's worth to invest time in this adventure..2 -
I gonna puke if I see more whining on android studio from a guy having 8GB of ram and running IDE emulator and a browser. To remind everyone, decent android phones have 4GB of ram or more. They have memory cards with io speeds comparable to SSD. They have 10 core CPUs. And still, people want to develop on potatoes.10

The guy who wrote a ton of legacy code at my company apparently had no idea that you need to close a file stream. And also that IO may throw exceptions.

So instead of drinking shit like Pepsi Max while coding on a weekend, and since it's so hot lately, I thought I'd buy a blender and some fruits and make frozen fruit drinks.
After unpacking the blender, I notice a booklet with a few recipes.
All I can say, is, ":/".
I'm thinking about making a frozen watermelon and peach drink right now. What do you guys like to drink when it's really hot (besides coffee)?

A while ago, i decided to finally learn a bit about the web stack (especially django) and create my first web page. The image shows what it currently looks like.
I am actually very happy with the result. It will be my personal little Home automation software, with progressive apps etc. It runs on the pi plattform and can currently switch an IO to a Relais, which in turn switches on a light.
The applications of this are really endless, which is quite cool and leads me to do more stuff at my home with it. So dear devRant: Does anybody know of some nice hackable light bulbs/spots for my home that i can use? Or other cool hackable hardware that could be applied?

Ffs, HOW!?!? Fuck! I need to get this rotten bs out.
RDS at its max capabilities from the top shelf, works OK until you scale it down and back up again. Code is the same, data is the same, load is the same, even the kitchen sink is the same, ffs, EVERYTHING is the same! Except the aws-managed db is torn down and created anew. From the SAME snapshots! But the db decides to stop performing - io tpt is shit, concurrency goes through the roof.
Re-scale it a few more times and the performance gets back to normal.
And aws folks are no better. Girish comes - says we have to optimize our queries. Rajesh comes - we are hitting the iops limit. Ankur comes - you're out of cpu. Vinod thinks it's gotta be the application to blame.
Come on guys, you are a complete waste of time for a premium fucking support!
Not to mention that 2 enhanced monitoring graphs show anythung but the read throughput.
Ffs, Amazon, even my 12yo netbook is more predictable than your enterprise paas! And that support..... BS!
We're now down to troubleshooting aws perf issues rather than our client's.... -
Junior dev here. Finishing a boot camp, actively going through a few job application processes.
One of the companies has given me a tech assignment (for a Graduate Junior position, mind you) that was titled Full Stack Mid Level Challenge. It took me a week to build an app they asked and do analitycs and refactoring of the second part of the task (I only had late evenings free to dedicate to that), it was my first time doing back-end in Node (my boot camp teaches PHP) so I basically learned to do it while doing this challenge.
They asked testing and clean architecture.
I submitted the assignment (I thought I would die while doing it, exhausted, I think I was brain dead for a short perio of time, but I submitted it on time).
They got back to me and we had already have a tech interview with the Leads that had live coding at the end. Don't have feedback yet, really won't be surprised for whatever comes, it was literarly my first interview, treating it like a valuable learning experience.
But. This rant is not about this. Thsi is just to put you in my mood.
This is the !rant:
My classmate from the bootcamp is probably already hired, or will be one of these days. As a tech challenge she was asked to do FizzBuzz kata. I repeat, FizzBuzz bloody kata!
Now, I am very happy for this person, the situation is complicated and this job is extremely needed.
But, please, explain to me, HOW??? How is it possible that selection criterias vary that much?
End of rant. Thank you very much.4 -
Built my first App - the BOFH returns
So I started to learn programming about 7 weeks ago, learned some Java, immersed myself in git and then via a friend got introduced to android studio. To get some practice I decided to code my own app, and what better way than to create a quote generator for the funny and creative error messages as seen in The Bastard Operator from Hell. Now I wrote the thing, started adding a feature and before I know it, it works and I'm contacting the original author, if I may publish it to the playstore.
Io and behold: Merely 32 hours after the idea had sparked, in an act of spontaneous madness I've pubished my first app.
This was an absolutely electrifying experience and a huge feeling of success to me, to see my own creation on my homescreen.
Sorry for annoying you with this antirant, but I just had to get this out!

The ridiculous and shameful story of how simply "installing Windows" saved my hard drive from the garbage.
(Also update on https://devrant.com/rants/3105365/)
It started with my root partition turning read-only all of a sudden. Some quick search suggested that I should check the sanity of my hard drive, by running a SMART test, which failed of course. I backed up my data using ddrescue and ran a badblocks over the whole thing, which found around 800 unreadable blocks in a row. I was ready to bid farewell to my drive, but as a last resort, instead of the trash, I brought it to this place where they claimed they can repair the damaged hard drives by "surgery".
To my surprise, they returned my drive the next week, saying it is all well now, and charged me 1/8 the price of a new drive, with a refund guarantee if there was a problem in two days. There was a problem right there: I ran another SMART test which failed again, and also the faulty blocks were still unreadable! So I stormed the place and called for my refund, showing the failed SMART report. The only answer I would get from the staff was "Have you tried installing Windows?".
I usually try to be patient in such situations; I really don't like to declare publicly that "not everyone uses that stinky piece of rotten software you call an OS", but their suggestion seemed totally irrelevant! I got all types of IO errors all over the damn thing and they told me to install Windows. Why? Because this was the only test they would rely on. At last I managed to meet the "technician" there and showed him the IO errors: tried to read the bad sectors with dd and failed. He first mumbled somethings like "Have you checked the connector?" or "Are these the same blocks?", but after he ran out of bullshit, he said "Why don't you just install Windows first and see if that helps?" and I was ready to explode in his face!
"You test drives by installing Windows, just because it will make a nasty NTFS partition and probably does an fsck? If you shut your mouth for a sec and open your eyes you'll see this is a shit load of IO errors we got here: You can't install Windows, you can't even make an NTFS here, because it will try to zero-the-fuck-out the damn partition and it will face the same fucking IO error that I'm showing you right now in almost one single fucking system call!"
"I don't know this kind of test you are using. We have our own tests and they've passed successfully. So all I can do is to give you a Windows CD if you want."
"I don't need a Windows CD. I will just try to make an NTFS partition on the error spot and I will fail."
"Ok. Then call me when your done."
I was angry, not only because I felt they're just trying to avoid a refund, but also because I knew I've lost my drive. But just with hope that I could get my money back, I made a small partition over the error spot and ran `mkfs.ntfs` on it. I was ready to show the failure to the guy, but I looked more precisely and saw that "the filesystem was created successfully!" I was sure something is nor write. I then successfully mounted the new partition, write over it and read it again. I even dd'ed the blocks again, and this time there was no IO error. All of a sudden everything was fine.
I didn't know what happened. Maybe it just needed a write, while I'd just tried to read from those blocks. But anyway, I didn't called the technician guy again. I just thanked one of the staff there and said that my problem was solved. I then ran a successful SMART test and then restored my backup. Ridiculous like that.
I'm still not sure if my drive will continue to live with no more problems. I also have no explanation for what happened. (I appreciate any help on this https://superuser.com/questions/...) But I really like to see the look on the poor guy's face when he finds out that trying to install Windows just saved my ass!10 -
Do you need a degree to become a software engineer ?
Now this is a question I’ve seen many people ask. I personally have no degree and I’ve been doing programming for the past 10 years (since I was 18 ). Whatever I learned, I learned from reading and watching tutorials.
So far It wasn’t a problem for me.
What do u guys think and what is your experience is this matter ?9 -

Today I finally solved a docker problem I was stuck with for 2 days.
For some reason it didnt want to download the needed images although colleagues could download the same images. Every time I tried it resulted in a Python IO error.
Today I had enough of it so asked if I could join another project. I had to download the exact same image for that project and it worked... Setting up the first project worked as well since I had these images already.
I still dont know why it didnt and later did work, but that is the life of devs.1 -

Anything from Udemy with instructors who don't speak CLEARLY, and instructors who fail to provide solid code explanations (ex: they just type some shit and expect us to understand what it's doing, and they move onto the next topic).
Add instructors who pretty much copy a tutorial verbatim - they just go through someone else's tutorial (without referencing the authors' work) and claim it as their own.
I'm sure I have more to add, but I'll stop here. :P3 -
Today I spent 9 hours trying to resolve an issue with .net core integration testing a project with soap services created using a third party soap library since .net core doesn't support soap anymore. And WCF is before my time.
The tests run in-process so that we can override services like the database, file storage, basically io settings but not code.
This morning I write the first test by creating a connected service reference to generate a service client. That way I don't need to worry about generating soap messages and keeping them in sync with the code.
I sent my first request and... Can't find endpoint.
3 hours later I learn via fiddler that a real request is being made. It's not using the virtual in-process server and http client, it's sending an actual network request that fiddler picks up, and of course that needs a real server accepting requests... Which I don't have.
So I start on MSDN. Please God help me. Nope. Nothing. Makes sense since soap is dead on .net core.
Now what? Nothing on the internet because above. Nothing in the third party soap library. Nothing. At this point I question of I have hit my wall as a developer.
Another 4 hours later I have reverse engineered the Microsoft code on GitHub and figured out that I am fucked. It's so hard to understand.
2 more hours later I have figured out a solution. It's pure filth..I hide it away in another tooling project and move all the filth to internal classes :D the equivalent of tidying your room as a kid by shoving it all under the bed. But fuck it.
My soap tests now use the correct http client with the virtual server. I am a magician.4 -

I do not understand how event loop of node is faster than per request new php fpm process or similar.
Imagine you have 10 users surfing your website. In PHP there will be 10 process working on each request.
Where as in NodeJS there is only 1 process taking each request one by one.
Now for the I/O part, it is going to take same time on completion. By the time the IO is completed and the control is back to NodeJs, It will eventually take the same time (the actual response delivered).
Am I missing something here ?4 -
To all the people who use laptops for coding, what are the most important things to look out for when getting one. As a desktop user, all of these machines seem underpowered and overpriced.
