In a user-interface design meeting over a regulatory compliance implementation:
User: “We’ll need to input a city.”
Dev: “Should we validate that city against the state, zip code, and country?”
User: “You are going to make me enter all that data? Ugh…then make it a drop-down. I select the city and the state, zip code auto-fill. I don’t want to make a mistake typing any of that data in.”
Me: “I don’t think a drop-down of every city in the US is feasible.”
Manage: “Why? There cannot be that many. Drop-down is fine. What about the button? We have a few icons to choose from…”
Me: “Uh..yea…there are thousands of cities in the US. Way too much data to for anyone to realistically scroll through”
Dev: “They won’t have to scroll, I’ll filter the list when they start typing.”
Me: “That’s not really the issue and if they are typing the city anyway, just let them type it in.”
User: “What if I mistype Ch1cago? We could inadvertently be out of compliance. The system should never open the company up for federal lawsuits”
Me: “If we’re hiring individuals responsible for legal compliance who can’t spell Chicago, we should be sued by the federal government. We should validate the data the best we can, but it is ultimately your department’s responsibility for data accuracy.”
Manager: “Now now…it’s all our responsibility. What is wrong with a few thousand item drop-down?”
Me: “Um, memory, network bandwidth, database storage, who maintains this list of cities? A lot of time and resources could be saved by simply paying attention.”
Manager: “Memory? Well, memory is cheap. If the workstation needs more memory, we’ll add more”
Dev: “Creating a drop-down is easy and selecting thousands of rows from the database should be fast enough. If the selection is slow, I’ll put it in a thread.”
DBA: “Table won’t be that big and won’t take up much disk space. We’ll need to setup stored procedures, and data import jobs from somewhere to maintain the data. New cities, name changes, ect. ”
Manager: “And if the network starts becoming too slow, we’ll have the Networking dept. open up the valves.”
Me: “Am I the only one seeing all the moving parts we’re introducing just to keep someone from misspelling ‘Chicago’? I’ll admit I’m wrong or maybe I’m not looking at the problem correctly. The point of redesigning the compliance system is to make it simpler, not more complex.”
Manager: “I’m missing the point to why we’re still talking about this. Decision has been made. Drop-down of all cities in the US. Moving on to the button’s icon ..”
Me: “Where is the list of cities going to come from?”
<few seconds of silence>
Dev: “Post office I guess.”
Me: “You guess?…OK…Who is going to manage this list of cities? The manager responsible for regulations?”
User: “Thousands of cities? Oh no …no one is our area has time for that. The system should do it”
Me: “OK, the system. That falls on the DBA. Are you going to be responsible for keeping the data accurate? What is going to audit the cities to make sure the names are properly named and associated with the correct state?”
DBA: “Uh..I don’t know…um…I can set up a job to run every night”
Me: “A job to do what? Validate the data against what?”
Manager: “Do you have a point? No one said it would be easy and all of those details can be answered later.”
Me: “Almost done, and this should be easy. How many cities do we currently have to maintain compliance?”
User: “Maybe 4 or 5. Not many. Regulations are mostly on a state level.”
Me: “When was the last time we created a new city compliance?”
User: “Maybe, 8 years ago. It was before I started.”
Me: “So we’re creating all this complexity for data that, realistically, probably won’t ever change?”
User: “Oh crap, you’re right. What the hell was I thinking…Scratch the drop-down idea. I doubt we’re have a new city regulation anytime soon and how hard is it to type in a city?”
Manager: “OK, are we done wasting everyone’s time on this? No drop-down of cities...next …Let’s get back to the button’s icon …”
Simplicity 1, complexity 0.16 -
Crap.. got myself into a fight with someone in a bar.
Hospitalized, turns out that my knee is bruised and my nose is broken. For some reason the knee hurts much more than the nose though.. very weird.
Just noticed that some fucker there stole my keychain USB stick too. Couldn't care less about the USB stick itself, got tons of those at home and hard drive storage even more so (10TB) but the data on it was invaluable. It held on a LUKS-encrypted partition, my GPG keys, revocation certificates, server backups and everything. My entire digital identity pretty much.
I'm afraid that the thief might try to crack it. On the flip side, if it's just a common Windows user, plugging it in will prompt him to format it.. hopefully he'll do that.
What do you think.. take a leap with fate and see how strong LUKS really is or revoke all my keys and assume my servers' filesystems to be in the hands of some random person that I don't know?
Seriously though.. stealing a fucking flash drive, of what size.. 32GB? What the fuck is wrong with people?34 -
I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.
So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.
It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.
Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).
Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!
The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.
Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.
So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.
There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

One:
Had a stack of harddrives with my important data, two USB drives and a 4.7gb disc, two or three cloud storage accounts.
Needed a restore:
Knocked the stack of hard drives onto the floor (all broken), stood on one of the flash drives, found the other one in a pocket of a pair of trousers which just came out of the washing machine, dvd too scratched to read and couldn't verify my cloud storage account because I lost the password to the connected email account and the backup email account to verify that one didn't exist anymore. Fucking hell.
Two:
Production database with not that much yet but at least some production data which wasn't backupped.
Friend: can I reboot the db machine?
Me: yup!
Friend: what's the luks crypt password?
Me: 😯😐😓😫😲😧😭
End of story 😅
For the record, the first one actually happened (I literally cried afterwards) and that taught me to update my recovery email addresses more often!9 -
This story starts over two years ago... I think I'm doomed to repeat myself till the end of time...
Feb 2014
[I'm thrust into the world of Microsoft Exchange and get to learn PowerShell]
Me: I've been looking at email growth and at this rate you're gonna run out of disk space by August 2014. You really must put in quotas and provide some form of single-instance archiving.
Management: When we upgrade to the next version we'll allocate more disk, just balance the databases so that they don't overload in the meantime.
[I write custom scripts to estimate mailbox size patterns and move mailboxes around to avoid uneven growth]
Nov 2014
Me: We really need to start migration to avoid storage issues. Will the new version have Quotas and have we sorted out our retention issues?
Management: We can't implement quotas, it's too political and the vendor we had is on the nose right now so we can't make a decision about archiving. You can start the migration now though, right?
Me: Of course.
May 2015
Me: At this rate, you're going to run out of space again by January 2016.
Management: That's alright, we should be on track to upgrade to the next version by November so that won't be an issue 'cos we'll just give it more disk then.
[As time passes, I improve the custom script I use to keep everything balanced]
Nov 2015
Me: We will run out of space around Christmas if nothing is done.
Management: How much space do you need?
Me: The question is not how much space... it's when do you want the existing storage to last?
Management: October 2016... we'll have the new build by July and start migration soon after.
Me: In that case, you need this many hundreds of TB
Storage: It's a stretch but yes, we can accommodate that.
[I don't trust their estimate so I tell them it will last till November with the added storage but it will actually last till February... I don't want to have this come up during Xmas again. Meanwhile my script is made even more self-sufficient and I'm proud of the balance I can achieve across databases.]
Oct 2016 (last week)
Me: I note there is no build and the migration is unlikely since it is already October. Please be advised that we will run out of space by February 2017.
Management: How much space do you need?
Me: Like last time, how long do you want it to last?
Management: We should have a build by July 2017... so, August 2017!
Me: OK, in that case we need hundreds more TB.
Storage: This is the last time. There's no more storage after August... you already take more than a PB.
Management: It's OK, the build will be here by July 2017 and we should have the political issues sorted.
Sigh... No doubt I'll be having this conversation again in July next year.
On the up-shot, I've decided to rewrite my script to make it even more efficient because I've learnt a lot since the script's inception over two years ago... it is soooo close to being fully automated and one of these days I will see the database growth graphs produce a single perfect line showing a balance in both size and growth. I live for that Nirvana.6 -
Well, it wasn't fun, but I switched jobs this month. And sadly, it was mostly because my old company started building custom applications for our larger customers. Now, normally that wouldn't be too bad (other than the fact that it distracts us form working on our main product...) but... it was decided that we would use the back end of our user-generated forms module as the data storage layer. Someone outside of my department thought it would be a great idea, and my boss kinda just rolled over without a fight because he always just figures he can "make it work" if he works hard enough...
You shoulda seen the database and SQL code...
Because of that decision, everything took at least 3x as long to write and there was always the looming possibility that the user could change the schema on a whim and break the app.
I think the reasoning behind it was to try and keep the customers tied to the aging flagship product (with a pricy subscription model), but IMO, it was not with it. Our efforts could've had much greater impact somewhere else. Nobody seemed to care what I thought about it though...
I had to start over as a front-end dev, but I'm trying to look on the bright side and seeing it as an opportunity to sharpen my skills in that area. I'm already learning a lot. And although it's a little scary at times, it's also so refreshing to work at a place where I know I'm not the smartest guy in the room.
To the future!5 -
The newest IPhone (Which specwise is good) is more expensive than the newest graphics cards that are coming out... h.o.l.y. s.h.i.t
and you know what? THE BEST MODEL IS 400 BUCKS MORE EXPENSIVE THAN A FUCKING 2080TI!
And you know what?
WHATS UP WITH STORAGE!
you go from 64Gb to 256 and 512 GIGABYTES OF DATA!!
Its like, Midrange storage to a Ton of Storage to HOLY SHIT WHO NEEDS THIS MUCH?!
and you know WHY they are doing this?
Because most of the people will buy the 256 or 512 model GUARANTEED! People behave like this! you dont believe me?
What if you gave a Big Popcorn box for 15 Bucks and the smallest one for 5 bucks, which one would you buy? The smaller one. (Most of the time) and why? because you only have 2 choices! If I gave you 3 choices: 5 for small, 10 for medium and 15 for large?
You wont buy the smallest one, because it doesnt make sense! THATS WHY AND NOW FUCK OFF AND YOU TOO APPLE GO SUCK COCKS OF YOUR FUCKING FANBOYS WHICH WILL PAY MORE!4 -
I've recently received another invitation to Google's Foobar challenges.
A while ago someone here on devRant (which I believe works at Google, and whose support I deeply appreciate) sent me a couple of links to it too. Unfortunately back then I didn't take the time to learn the programming languages (Python or Java) that Google requires for these challenges. This time I'm putting everything on Python, as it's the easiest language to learn when coming from Bash.
But at the end of the day.. I am a sysadmin, not a developer. I don't know a single thing about either of these languages. Yet I can't take these challenges as the sysadmin I am. Instead, I have to learn a new language which chances are I'll never need again outside of some HR dickhead's interview with lateral thinking questions and whiteboard programming, probably prohibited from using Google search like every sane programmer and/or sysadmin would for practical challenges that actually occur in real life.
I don't want to do that. Google is a once in a lifetime opportunity, I get that. Many people would probably even steal that foobar link from me if they could. But I don't think that for me it's the right thing to do. Google has made a serious difference by actually challenging developers with practical scenarios, and that's vastly superior to whatever a HR person at any other company could cobble together for an interview. But there's one thing that they don't seem to realize. A company like Google consists of more than just developers. Not only that, it probably consists - even within their developer circles - of more than just Python and Java developers. If any company would know about languages that are more optimized such as C, it would be Google that has to leverage this performance in order to be able to deliver their services.
I'll be frank here. Foobar has its own issues that I don't like. But if Google were a nice company, I'd go for it all the way nonetheless - after all, they are arguably the single biggest tech company in the world, and the tech industry itself is one of the biggest ones in the world nowadays. It's safe to say that there's likely no opportunity like working at Google. But I don't think it's the right thing. Even if I did know Python or Java... Even if I did. I don't like Google's business decisions.
I've recently flashed my OnePlus 6T with LineageOS. It's now completely Google-free, except for a stock Yalp account (that I'm too afraid to replace with my actual Google account because oh dear, third-party app stores, oh dear that could damage our business and has to be made highly illegal!1!). My contacts on that phone are are all gone. They're all stored on a Google server somewhere (except for some like @linuxxx' that I consciously stored on device storage and thus lost a while back), waiting for me to log back in and sync them back. I've never asked for this. If Google explicitly told me that they'd sync all my contacts to my Google account and offer feasible alternatives, I'd probably given more priority to building a CalDAV and CardDAV server of my own. Because I do have the skills and desire to maintain that myself. I don't want Google to do this for me.
Move fast and break things. I've even got a special Termux script on my home screen, aptly named Unfuck-Google-Play. Every other day I have to use it. Google Search. When I open it on my Nexus 6P, which was Google's foray into hardware and in which they failed quite spectacularly - I've even almost bent and killed it tonight, after cursing at that piece of shit every goddamn day - the Google app opens, I type some text into it.. and then it just jumps back to the beginning of whatever I was typing. A preloader of sorts. The app is a fucking web page parser, or heck probably even just an API parser. How does that in any way justify such shitty preloaders? How does that in any way justify such crappy performance on anything but the most recent flagships? I could go on about this all day... I used to run modern Linux on a 15 year old laptop, smoothly. So don't you Google tell me that a - probably trillion dollar - company can't do that shit right. When there's (commercialized) community projects like DuckDuckGo that do things a million times better than you do - yet they can't compete with you due to your shit being preloaded on every phone and tablet and impossible to remove without rooting - that you Google can't do that and a lot more. You've got fucking Google Assistant for fucks sake! Yet you can't make a decent search app - the goddamn thing that your company started with in the first place!?
I'm sorry. I'd love to work at Google and taste the diversity that this company has to offer. But there's *a lot* wrong with it at the business end too. That is something that - in that state - I don't think I want to contribute to, despite it being pretty much a lottery ticket that I've been fortunate enough to draw twice.
Maybe I should just start my own company.6 -
I got the task to set up an NAS, because "server has too high maintenance costs".
I built two databases for this company and the big boss loved my work. (spoiler:not because my work was outstanding but because I, as a student, am cheap and willing to learn).
And now? Reality hit me for good. I looked for a enterprise worthy NAS solution, sent them the details, they bought it and now it's 00:00 in Germany and I'm sitting in the empty hall, trying to configure the storage to work like they want it. On a friday. Alone. As the only member of the IT-team. With way to much responsibility.
So... Yea, fuck you for good. I hope your backup gets an disk error at the same moment i quit. (but first gimme mah monney)3 -
A story from around 2005:
Customer laying out specifications: “We expect this software to need to last 25 years or so, and it will need to keep historical file processing data by dates for at least that long, assume storage is no issue.”
Devs at the time: “look best I can do is support that start with 200 or 201, anything else is really too much to ask. Also understanding how to work with dates at all and not just string manipulation is waaaaayyy hard yo.”
Fuck you lazy motherfuckers. This is why people thought Y2K would be a problem. -
hey ranteros! i like to dream and i know many of us dream of a nice machine to do anything on it, if you want to post the specs of your ideal build(s) (even a laptop, pre-built pc, space gray macbook pro... doesn't matter). and your current one.
here's mine:
ideal: {
type: desktop-pc,
cpu: intel i7-8700K (coffee lake),
gpu: nvidia geforce gtx 1080ti,
ram: 32gb ddr4,
storage: {
ssd: samsung 960 evo 500gb,
hdd: 2tb wd black
},
motherboard: any good motherboard that supports coffee lake and has a good selection of i/o,
psu: anything juicy enough, silver rated,
cooling: i don't care about liquid cooling that much, or maybe i'm just afraid of it,
case: i accept any form factor, as long as it's not too oBNoxi0Us,
peripherals: {
monitor: 1080p, maybe 1440p, i can't 4k because of the media i consume (i have tons of shit i watch in 720p) + other reasons,
keyboardmousecombo: i like logitech stuff, nothing fancy, their non mechanical keyboards are nice, for mice the mx master 2 is nice i think, i also don't care about rgb because i think it's too distracting and i'm always in darkness so some white backlight is great
},
os: windows 10, tails (i have some questions about tails i'll be asking in a different post,
}
i think this is enough for ideal, now reality:
current: {
type: laptop,
brand: acer (aspire 7736z),
cpu: pentium dual-core 2.10ghz,
gpu: geforce g210m 2gb (with cuda™!),
ram: 4gb ddr3,
storage: hdd 500gb wd blue 5400rpm (this motherfucker stood the test of time because it's still working since i bought this thing (the laptop as it is) used in late 2009 although it's full of bad sectors and might anytime, don't worry i have everything backed up, i have a total of 5 hdds varying from 320gb to 1tb with different stuff on them),
screen: 17 inch hd-ready!!! (i think it's a tn panel), i've never done a test on color accuracy, but to my eyes it's bright, colorful, and has some dust particles between the lcd and backlight hah,
other cool things: dvd player/burner, full-sized keyboard with numeric keypad, vga, hdmi, 4 usb ports, ethernet, wi-fi haha, and it's hot, i mean so hot, hotter than elsa jean and piper perri combined,
os: windows 10, tails
}
if you read this whole thing i love you, and if you have some time to spare on a sunday you can share your dream rig and the sometimes cruel current one if you dare. you don't have to share them both. i know many will go b.o.b and say "what you're hoping to accomplish, i already did bitch.", that's cool as well, brag about your cool rig!8 -
I continue to internally read and study about Smalltalk in an effort to see where we might have FUCKED UP and went backwards in terms of software engineering since I do not believe that complex source code based languages are the solution.
So I have Pharo. Nothin to complex really, everything is an object, yet, you do have room for building DSL's inside of it over a simple object model with no issue, the system browser can be opened across multiple screens (morph windows inside of a smalltalk system) for which you can edit you code in composable blocks with no issues. Blocks being a particular part of the language (think Ruby in more modern features) give ample room for functional programming. Thus far we have FP and OO (the original mind you) styles out in the open for development.
Your main code can be executed and instantly ALTER the live environment of a program as it is running, if what you are trying to do is stupid it won't affect the live instance, live programming is ahead of its time, and impressive, considering how old Smalltalk is. GUI applications can be given headless (this is also old in terms of how this shit was first distributed) So I can go ahead and package the virtual machine with the entire application into a folder, and distribute it agains't an organization "but why!!!! that package is 80+ mbs!") yeah cuz it carries the entire virtual machine, but go ahead and give it to the Mac user, or the Linux user, it will run, natively once it is clicked.
Server side applications run in similar fashion to php, in terms of lifecycles of request and how session storage is handled, this to me is interesting, no additional runtimes, drop it on a server, configure it properly and off you go, but this is common on other languages so really not that much of a point.
BUT if over a network a user is using your application and you change it and send that change over the network then the the change is damn near instant and fault tolerant due to the nature of the language.
Honestly, I don't know what went wrong or why we are not bringing this shit to the masses, the language was built for fucking kids, it was the first "y'all too stupid to get it, so here is simple" engine and we still said "nah fuck it, unlimited file system based programs, horrible build engines and {}; all over the place"
I am now writing a large budget managing application in Pharo Smalltalk which I want to go ahead and put to test soon at my institution. I do not have any issues thus far, other than my documentation help is literally "read the source code of the package system" which is easy as shit since it is already included inside. My scripts are small, my class hierarchies cover on themselves AND testing is part of the system. I honestly see no faults other than "well....fuck you I like opening vim and editing 300000000 files"
And honestly that is fine, my questions are: why is a paradigm that fits procedural, functional and OBVIOUSLY OO while including an all encompassing IDE NOT more famous, SELECTION is fine and other languages are a better fit, but why is such environment not more famous?9 -
LXC, no doubt.
I mean to be fair, LXC is an amazing container runtime once you manage to set it up. But setting it up is the hard bit. Starting off with LXC 2.x, it was a nightmare to find out how to get things like the storage backends working. But with ZFS it ended up being alright. Find some arcane values to stick in the /etc/lxc/default.conf to use ZFS as the backend and then the default storage location on those ZFS pools (I'll get back to that later), and it worked alright. Again, once it works it's great, but setting it up and finding the right configuration keys is absolute hell.
So, LXC 2.x for a while and a few months ago I finally ended up upgrading to 3.x. Every single configuration key changed. Every single one of them, and that's why I had to 1) learn LXC all over again, and 2) redeploy each and every one of my containers. That process is still not entirely completed. ZFS backend was once again a dive into arcane configuration keys found on forums and whatnot. Yeah.. official documentation has none of it. Oh and in 3.x you now also have to dodge the torrent of "just use LXD m8" messages. Yeah, very helpful when LXD is also the ONLY way to reasonably configure it. Absolutely beautiful. Oh and as far as the ZFS default storage location goes (such as ssd/lxc/ct)? Yeah forget about it. There's no configuration option for it anymore, and the default is "lxc". In ZFS lingo that means that LXC has the audacity to demand a whole pool for itself. No. No you don't deserve a whole pool for yourself. But hey at least you can define the storage location to use in the lxc-create command! Every single time you have to define it in lxc-create. I abstracted it away into my own LXC interface, so no big deal really. But yeah... That could absolutely be better. And in 2.x it was actually better.
Oh and btrfs, the filesystem I'd like to use on low memory systems because ZFS' ARC is too much on such systems? Yeah forget about it. I still have no idea how to do it. Thank you LXC and its amazing documentation!
And if you want the icing on the cake for LXC's terrible documentation, see their repo's index page at https://github.com/lxc/lxc/.... Yeah, it's totally still at 2.x... That's how well they maintain that. Even Debian has 3.x now. And if you look at the branches, you'll find that even 4.x is already available and considered stable. -
I was trying to make a circular buffer in C++. I was also trying to expose iterators for using the buffer with STL algorithms. I kept trying to think about how to add the functions needed to manipulate the existing internal iterators to not exceed the bounds of the buffer. Then I realized I was "too close" to the problem. There was no way I could properly control the internal iterators of the storage vector I was using. Not without giving too much power to the user of my library. So I abstracted the iterators up one level. Hid all the details of the internal iterator and made a new iterator.
The solution of abstracting the iterator was not the epiphany. The epiphany was if you are struggling with how to solve a particular problem. You keep running into problems with how to represent something, there is too much power available at a particular representation, or the object you are trying to make work just don't fit. This is when you should consider abstracting a level up. Take a higher look at the problem and simplify the interface.
Abstraction could be a number of things. Divide and conquer, hiding details, specializing an object, etc. Whatever tool is needed to make the problem more consumable to your brain. -
I had a discussion with my colleagues about my bachelor thesis.
Together we created within the last 18 month a REST-API where we use LDAP/LMDB as database (tree structured storage). Of course our data is relational and of course we have a high redundancy there. It's a 170 call API and I highly doubt that it's actually conforming REST.
Ensuring DB integrity is done in the backend and coding style there is "If we change it at one place, let's make sure to also change it everywhere else", so you get a good impression how much of spaghetti code we have there.
Now I proposed to code a solution in my bachelor thesis where we use a relational database (we even have an administrated Oracle DB with high availability) and have a write-only layer to also store the data in LDAP but my colleagues said that "it would add too much complexity to the system".
Instead I should write the relational layer myself and fetch the data somehow from the existing LDAP tree.
What the actual fuck, spaghetti code is what makes the system really unnecessarily complex so that no one will understand that code in 2 years.
Congratulations, you just created legacy code that went into production in 2018 while not accepting the opportunity to let that legacy code get eliminated.
Now good luck with running and maintaining that system and it's inconsistencies.1 -
1) Reader Rabbit on an Apple IIGS in the late 80s. I might've been in Kindergarten. Found the boxes stored in an unreachable storage area at my dad's house recently. Knowing how he took care of things, it probably still works. He won't let me touch it.
2) Fast forward to early middle school, Ultima VII on an NEC desktop, 90s. That game was great but also a pain in the ass. Had to make a startup floppy disk to help with memory allocation and something else. Learned DOS things. For some reason the disk wouldn't work from one day to the next so would have to reconfigure it frequently. Also learned the hard way not to fork too much with autoexec.bat during this period. -
I hate group project so much.
I yet again successfully stirred up a big drama in my project group. For project, I proposed a CDN cache system for a post only database server. Super simple. I wanted to see what ideas other people come up with. So I said I am not good at the content and the idea is dumb. Oh man, what a horrible mistake. One group member wants to build a chat app with distributed storage. We implemented get/put for a terribly designed key value store and now they want to build a freaking chat app on top of a more stupid kV store using golang standard lib. I don't think any of those fools understand the challenges that comes with the distributed storage.
I sent a video explaining part of crdt. "That's way too complicated. Why are you making everything complicated."
Those fools leave too much details for course stuff's interpretation and says
"course stuff will only grade the project according to the proposal. It's in the project description".
I asked why don't they just take baby steps and just go with their underlying terribly designed kV store.
"Messaging app is more interesting and designing kV store with generic API is just as difficult"
😂 Fucking egos
Then I successfully pissed off all group members with relatively respectful words then pissed off myself and joined another group.1 -
because I lacked a portable storing solution (pockets weren't allowed), I couldn't find anything better than using my own skull as a storage box. It turned out it had way more room than expected. The brain itself is quite small, and the whole frontal lobe & the space around the brain is completely empty. Initially, opening the skull was scary and cumbersome, but the more you do it, the easier it gets. Once upon a time, when I tried to pop an acne on my forehead, the hole was revealed, and it led to the storage space beneath. I have no idea how it happened, but apparently the skin is too thin. The bone also looks much thicker from the inside. There were two wires — red and black — leading to a standard PC speaker every old computer had. I wasn't a cyborg, mind you, I merely put that speaker there for storage. The acne hole healed with those wires exposed, leaving a permanent mark due to the wire coloring pigment dissolving in my skin.
I used that storage space to hide the contents of some parcels I was processing back then. I was stealing things. Eventually, my coworker — Bruce Willis — confronted me, and I had to strangle him. My arm became very flexible, and I was able to wrap it around his neck several times during a chokehold. It didn't end well for both of us. -
My first CS class is a basic introductory C++ course. Won't even be going into OOP.
So I want to use my own laptop for the course, but I have a Mac. Thought I could use Visual Studio for Mac for the class, but turns out Visual Studio for Mac is really only for Multiplatform development with C#. Ok, then, screw that. Just wasted 20GB and an evening installing that just to uninstall it.
I'm using JetBrain's CLion for now, but apparently we'll be doing some graphics work later this semester so I'm going to need to install Windows via Bootcamp and Visual Studio there... but my SSD is too small...
I currently have Windows/Bootcamp installed on a 1TB external hard disk but that is slow af. My SSD is only 250GB and I've already used half of it for various programs I need (Adobe crap plus Logic crap cuz I make videos and music).
My only option here is to buy a new SSD but only one manufacturer sells those (OWC), and a 1TB SSD is stupid expensive, $700 almost as much as I paid for this laptop used.
So, I guess I'm just kinda deciding right now whether upgrading storage is really worth it...6 -
You know when I think back to the ideas I've had and the things I've worked on. I'm having difficulty, with the exception of certain far out projects that were like unattainable, in thinking of anything I've done or thought of that does not involve: data visualization, data gathering, encryption/obfuscation, inventory/storage and/or communication.
am I just unimaginative ?
I did have an idea for a code translator and how it would work and what interfaces you'd have to adopt and how you'd attack implementing things that don't translate well like c++ to js for example. or c++ to c# for that matter ! but I never got far into it. though that would have been attainable as long as you had easy ways of generating bindings.
i mean pathing and navigation were things I thought of too but... that would pretty much be implementing someone else's stuff4 -
Lecturer : Today you can save data into the internet.
The internet is not a storage device 🤦♂️
Correct terminology when talking to computer science finalists too much to ask?
And we complain about the government.1
