I was in a hostel in my high school days.. I was studying commerce back then. Hostel days were the first time I ever used Wi-Fi. But it sucked big time. I'm barely got 5-10Kbps. It was mainly due to overcrowding and download accelerators.

So, I decided to do something about it. After doing some research, I discovered NetCut. And it did help me for my purposes to some extent. But it wasn't enough. I soon discovered that my floor shared the bandwidth with another floor in the hostel, and the only way I could get the 1Mbps was to go to that floor and use NetCut. That was riskier and I was lazy enough to convince myself look for a better solution rather than go to that floor every time I wanted to download something.

My hostel used Netgear's routers back then. I decided to find some way to get into those. I tried the default "admin" and "password", but my hostel's network admin knew better than that. I didn't give up. After searching all night (literally) about how to get into that router, I stumbled upon a blog that gave a brief info about "telnetenable" utility which could be used to access the router from command line. At that time, I knew nothing about telnet or command line. In the beginning I just couldn't get it to work. Then I figured I had to enable telnet from Windows settings. I did that and got a step further. I was now able to get into the router's shell by using default superuser login. But I didn’t know how to get the web access credentials from there. After googling some and a bit of trial and error, I got comfortable using cd, ls and cat commands. I hoped that some file in the router would have the web access credentials stored in cleartext. I spent the next hour just using cat to read every file. Luckily, I stumbled upon NVRAM which is used to store all config details of router. I went through all the output from cat (it was a lot of output) and discovered http_user and http_passwd. I tried that in the web interface and when it worked, my happiness knew no bounds. I literally ran across the floor screaming and shouting.

I knew nothing about hiding my tracks and soon my hostel’s admin found out I was tampering with the router's settings. But I was more than happy to share my discovery with him.

This experience planted a seed inside me and I went on to become the admin next year and eventually switch careers.

So that’s the story of how I met bash.
Thanks for reading!

My teacher at school who taught me programming. We were taught Java.

You see, Java is not a beginner's language, most say. But the way she taught it, the examples, the analogy, the explanation; she made it so easy.

She made us execute our first Hello World program (using BlueJ) and proudly said, "you're all programmers now!", that was when fascination took me over. I remember​ that moment till today.

Also, unlike regular exams, the programming exams required extreme competency. Marks were split up for algorithm and syntax. There were also questions like find the error in this algorithm for this output. She would always surprise us at the exams!

I had several glorious moments in class by being the first to answer most of her questions. At 13, it was kind of a big deal for me.
(Okay, who am I kidding, it still is :-P)

*sigh*

It was mostly just self learning from there. I switched schools and then there was college. Attending classes in college was like going to the gym with fat trainers. Utterly useless :-/ It just made me appreciate her even more.

My output of 5 hours of work: changing a 'b' to a 'B'.

5 hours working out what the stupid cryptic error message means and reading documentation, 5 minutes to change and test the difference.

I was taking an introductory programming course. One assignment was to do a little payroll program, including some data validation. The program was supposed to accept terminal input and send output back to either the console or a printer.

Suddenly the printer began spewing out paper like crazy. One of the students (a particularly mouthy woman) had programmed a less-than-helpful error message ("YOU ARE WRONG") and then not provided any exit from the error-checking logic -- the program just re-read the last (failing) input and re-tested it. All in all, it was a very nice infinite loop.

After spitting through about fifty pages of "YOU ARE WRONG," somebody cut power to the printer, and the instructor had to flush the print queue manually. He went back to the student and asked if she had tested the program by sending the output to the console before trying to print it, and she said, yes, she had tested it on the console and ended up with a screen full of "YOU ARE WRONG" messages. Why, then, had she sent her output to the printer? "I thought I would be daring!"

Have you guys heard about blind coding?

I had been to competition, first round was quiz.
That was quite easy, though most of the questions were incomplete and didn't make any sense.

They have provided an app. We use that to check the result.

So first round is over, 1 hour later my friend called me asked whether I'm qualified for the next round . I checked the results and my name wasn't there. I was very disappointed.

I left that place after I saw my result. I got a bus which goes to my place.

After 10 minutes, I got a call from the event head asking why I didn't attend second round 😑. I asked why name wasn't there on the result, for which he replied with "database updatation error".

I got down in the next stop and took a bus again to that place.

I reached there, second round was started, First part was debugging. It was easy, I debugged the given program and got the desired output.
Second part was coding. A guy showed a problem to solve and told me to read it quickly . I did as he told.
He opened Dev C++ and gave me a paper to write the program .

When I was about to start typing, he turned off the monitor and told I should write it on paper first and type the program having monitor turned off. 😨

I wrote and typed the program without seeing.
After 30 minutes a college lecturer came to give marks. He told me to compile the program.

TBH, there were many typing mistakes. As header file spelling was wrong it showed only one error.

Him: Huh, cool only one error, well done. *noted that and walked to a guy next to me*

Ok, so teacher (which should be something like a professional dev or whatever) assigned us a homework for a Christmas (I dont care, I can complete his assignments in like 10 minutes max). We have to do some simple shit in C++, just some loops and input + output. Nothing hard. He challenged me to write it as short as possible, so I did. My classmates have codes around 60 to 70 lines long (after propper formating). I made it 20 lines long using some pointer magic and stuff like that. I tried my code, it ran fucking perfectly, so I sent that to him. He replied that the code does not work. I tried to recompile it and it ran perfectly. Again, it does not work. Afeter 13 fucking emails he fucking finally sent me the error message. Some fucntion was not found (missing some library but literally everywhere else it works without it...). Thats strange, because it run perfectly on my Fedora with CLion, so I switch to Windows and try to run same code in Visual Studio (which we are using in school btw). Works perfectly. So I start arguing with the teacher more and more. I tried around 10 online compilers. Works fuckng everywhere. Teacher is pissed, me too. So I rewrote my whole code, added comments and shit, reinvented wheel literally everywhere. Now I have C99 standardised code over 370 lines long that run even on a fucking arduino after changing input output methods so it can work with it. It (suprisingly runs) on his PC too.

After a bit more arguing, he said that he is using CodeBlocks from fucking 2015. Wow. Just fucking wow. Even our school has some old Visual Studio (2007 I guess) and it worked there.

Wow i must have been brain dead when i wrote this code. Needed to exclude certain elements from response for the the list of objects.

for (obj : objects) {
If (obj.skipFromResponse()) {
break
}
add obj to response
}

I used break instead of continue at the if condition which meant it would break out of the loop at the first instance of condition being met.

This went through qa and has been in production for 4 weeks so how did this not break before. Well little did i know the list of objects was sorted and all the test data, qa data and everything so far in production coincidentally only had the last element with matching condition. This meant it returned everything correctly so far.

Today was the first time there was a situation where this caused incorrect output. Luckily as soon as I heard the description of the issue I remembered to check the merged PR and hung my head in shame for making such trivial error. I must have written way more complicated code without any problem but this made me embarrassed to even admit. 🤦‍♂️

PHP arrays.

The built-in array is also an hashmap. Actually, it's always a hashmap, but you can append to it without specifying indexes and PHP will use consecutive integers. Its performance characteristics? Who knows. Oh, and only strings, ints and null are valid keys.

What's the iteration order for arrays if you use them as hashmaps (string keys)? Well, they have their internal order. So it's actually an ordered hashmap that's being called an array. And you can produce an array which has only integer keys starting with 0, but with non-sequential internal (iteration) order.

This array weirdness has some non-trivial implications. `json_encode` (serializes argument to JSON) assumes an array corresponds to a JSON array if its keys are consecutive integers in increasing order starting with 0, otherwise the array becomes a JSON object. `array_filter` (filters arrays/hashmaps using callback predicate) preserves keys, so it will punch holes in the int key sequence if non-last items are removed, thus turning arrays into hashmaps and changing your JSON structure if you forget to discard keys before serialization.

You may wonder how JSON deserialization works, then? There's a special class for deserialized JSON objects, `stdClass`. It's basically a hashmap too, but it's an object, not an array, and all functions that would normally accept arrays won't work with it. So basically its only use is JSON (de)serialization. You can even cast arrays to objects, producing `stdClass`.

Bonus PHP trivia:

Many functions return nonsensical values. `preg_match`, the regex matching function, returns 1 for success, 0 for no matches and false for malformed regular expression. PHP supports exceptions, so it could just throw one on errors. It would even make more sense to return true, false and null for these three cases. But no, 1, 0 and false. And actual matches are returned by output arg.

`array_walk_recursive`, a function supposed to recursively apply callback to each element of an array. That's what docs say. It actually applies it to leafs only. It will also silently accept object instead of array and "walk" it, but without recursing into deeper objects.

Runtime type enforcing is supported for function arguments and returned values. You can use scalar types, classes, array, null and a few special keywords. There's also a `mixed` keyword, which is used in docs and means "anything". It's syntactically valid, the parser will accept it, but it matches no values in runtime. Calling such function will always cause a runtime error.

Strings can be indexed with negative integers. Arrays can't.

ReflectionClass::newInstanceWithoutConstructor: "Creates a new class instance without invoking the constructor". This one needs no commentary.

`array_map` is pretty self-explanatory if you call it with a callback and an array. Or if you provide more arrays of equal length via varargs, callback will be called with more arguments, one from each array. Makes sense so far. Now, you can also call `array_map` with null instead of callback. In that case it treats provided arrays as rows of a matrix and returns that matrix, transposed.

For fucks sake python.
Reminder to the morons like me still using python:
Notepad++ is not a real IDE and Console output is not a real debugger.

And here we see the absolutely dogshit worthless error output of python:

Says its the fucking return line where the problem is. Besides the problem being between my fucking ears apparently, it took a fucking double take to realize I had capitalized the class keyword.

Best:
Really getting into Rust. It has taught me so many things.
1. Null is evil
2. Sum types are amazing
3. Compiler can actually have good error output
4. Multi threading is actually really scary if you don't have a compiler to back you up

Worst:
I had to deal with SSIS. It has also taught me many things:
1. No matter how 'mature' a product is, it can be awful. Simply dump a random error code, the user can figure out what went wrong, no need for good error messages.
2. The modern concept of the database is crap. It's a gigantic global state that is used by everyone and owned by no one.
3. Don't use tools that aren't made to be used with version control.
4. Even when you tell your team that it's bad, you will be ignored.

Training model for 3 days now. Turns out there is a hidden
minor-bug causing a major bias on output. The result is actually within a error margin. But this is so unnecessary. Should i start over?

So this dev writes me an email following a blog post I wrote for their job that they "have an error" - they don't show any output, what the error message is or anything. How can I help if you dont specifically state your problem? I'm not going to do your job for you!

and now its finally come full circle: they said they asked chatgpt and bard but it "just didnt work" - well yeah, those were trained on internet content from over a year ago - the api and tools have changed!

painful and annoying times ahead i'm afraid

you still need to do the damn work, i will stand by the fact that LLMs are overhyped non-panacea till i'm dead

Okay, so I have to write a script that will get user data from an AD, additional information from an XML, combine those two to get boss user relationship and output that mess into an excel sheet.
Oh, and both sources are ofc completely inconsistent. So I need full error handling on everything.
Aaaaaaand I have to write it in VB script... Using np++... Without plugins...
I hate my life!

Me : *testing json output on pc by sending items with GET*
App : *app crashing with only recyclerview error*
Me : *debugging the app for 2 hours and testing ways to do another adaptor *
Me : fuuuuuuuuuuuuuuuuu... I used POST to get the data on app and forgot to change $_GET $_POST
Lesson learned. Always check the input first
Im ashame of my self #crysinthecorner

I started learning Golang today and really like it.

The error handling is *excellent*. It always works the same way and is standardized, unlike the hell that NodeJS error handling is (.catch(), try).

Modules confused the fuck out of me. I eventually figured out how they worked, but Go really doesn't try to make it easy to have multiple source folders...

I'll probably be re-writing my Discord Bot in Golang soon. Being able to have just one binary output will make things infinitely easier. Compile-time variables are another feature that's nice and easy to implement.

The goal is only having to upload a single binary to deploy on production from my CI script that has all keys and stuff inside. Feels good to finally throw all that old bad JS code out and starting completely fresh.

lately my IT mantra in the vein of "have you tried turning it off and back on again" has become "did you check the logs for error output"😡

NOTE to all developers of any level: if you want help do your due diligence! Check the logs, try to step debug and at the very least please at least pretend to perform a cursory search

Dockers JSON output is garbage.

First, you'll get no JSON per se.

You get a JSON string per image, Like this:

{...} LF
{...} LF
{...} LF

Then I tried to parse the labels.

It looked easy: <Key>=<Value> , delimited by comma.

Lil oneliner... Boom.

Turns out that Docker allows comma in the value line and doesn't escape it.

Great.

One liner turns into char by char parser to properly tokenize the Labels based on the last known delimiter.

I thought that this was a 5 min task.

Guess what, Docker sucks and this has turned into try and error...

For fucks sake, I hated Docker before, but this makes me more angry than anything else. Properly returning an parseable API isn't that hard :@

Rust: Unclear error output is seen as a compiler bug.
Me: 👏

SSIS & SQL Server: Unclear or absent error output is seen as an enterprise feature. It's so mature!
Me: 😩

Here is another Tester story for you!

Tester: We have a problem with the application and it says that we cant process the queue to store the objects in the database.
Me: Can we reproduce it easily?
Tester: Yes..
Me: Ok, I'll add some debug for you so that you can see the error and the worker status more easily.
Tester: Great!

<10 minutes later>
After adding the debug output and installing it on his test cluster this happens...
Me: The debug version is installed.
Tester: Ok, great!
Me: How fast does it take to reproduce?
Tester: Well... It happened this morning at 9
Me: Ok..? But are you able to reproduce the issue at all?
Tester: No... i don't think so...

I'm trying to deploy an Azure Function via Visual Studio. VS gives me this error:

Publish has encountered an error.
Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details.

A diagnostic log has been written to the following location:
"C:\Users\myusername\AppData\Local\Temp\tmp16F8.tmp"

Let's check the log then!

"Microsoft.WebTools.Shared.Exceptions.WebToolsException: Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details. "

Fucking piece of crap

I hate dev politics...

PM: Hey there is a weird error happening when I upload this file on production, but it works on our test environments.

Me: After looking at this error, I don't find any issues with the code, but this variable is set when the application is first loaded, I bet it wasn't loaded correctly our last deployment and we just need to reload the application.

Senior Dev: We need to output all of the errors and figure out where this error is coming from. Dump out all the errors on everything in production!!

Me: That's dumb... the code works on test... it's not the code.. it's the application.

Senior dev: %$*^$>&÷^> $

Me: Hey I have an idea! If test works... I can go ahead and deploy last week's changes to prod and dump those errors you were talking about!!

Senior Dev: OK

Me: *runs Jenkins job the deploys the new code and restarts the application*

PM: YAY you fixed it!!

Senior Dev: Did you sump put those errors like I said.

Me: Nope didn't touch a thing... I just deployed my irrelevant changes to that error and reloaded the application.

I'm just trying to install a program… Literally FOUR HOURS and over a MILLION lines of GCC warning output later:
==> ERROR: A failure occurred in build().
Aborting...
-> error making: lib32-qt4

An anti-rant: I just made some code and out of nowhere it suddenly had an awesome feature that I didn't even program. No, not a euphemism for "bug", an actual feature.

Here's the story: A few months ago I made a shortcut for "System.out.println(…)" called "print(…)". Then I developed it further to also print arrays as "[1,2,3]", lists as "{1,2,3}", work with nested arrays and lists and accept multiple arguments.
Today I wanted to expand the list printing feature, which previously only worked for ArrayLists, to all types of List. That caused a few problems, but eventually I got it to work. Then I also wanted to expand it to all instances of Collection. As a first step, I replaced the two references to "List" with "Collection" and magically, no error message. So I tested it with this code:

HashMap<Integer, String> map = new HashMap<>();
map.put(1, "1");
map.put(2, "");
map.put(3, "a");
print(map);

And magic happened! The output was:

{1=1, 2=, 3=a}

That's awesome! I didn't even think yet about how I wanted to display key-value pairs, but Java already gave me the perfect solution. Now the next puzzle is where the space after the comma comes from, because I didn't program that in either.

I feel a bit like a character in "The subtle knife", who writes a barebones program to communicate with sentient elementary particles (believe me, it makes sense in context) and suddenly there's text alignment on the left and right, without that character having programmed any alignment.

I like my log messages to indicate automatically where in the code something happened, so that I can easily identify where a message originated from while tracking down problems.

In C/C++ this is nice and easy - write a logging routine, wrap it in macros for the different log levels and have that automatically output __FILE__, __LINE__ etc.

I wanted to do something similar in NodeJS, as I'd found myself manually writing the file name in the log message and then splitting functionality out into new files and it became a mess.

The only way I found to be able to do this was to create an "Error" object and access the "stack" member of it. This is a string containing a stack backtrace, suitable for writing to console/file. I just wanted the filename/line/routine.

So I ended up splitting the string into lines, then for each of the lines, trimming the surrounding spaces (or tabs?), and parsing them to see if the stack entry is inside my logger module. The first entry outside of that module must therefore be the thing that called it, so I then parse out the routine or object and method, filename and line number.

It's a lot of clumsy work but the output is pretty neat. I just wish it were simpler!

Got tired of Windows 10 giving me BSODs

Tried fixing it (previous rant)

Decided to get rid of it

Purged Windows 10 along with Mint for good

Booted Solus (It's awesome)

Installing..

Installation failed - Input/Output error(5)

?

Maybe ISO got corrupted

Downloaded ISO again (painfully slowly)

Installing...

Success!

Booted to Login screen

Incorrect username/password (shit)

Tried again x times (absolutely correct username and password, I'm sure)

Doesn't work

Booted from the same USB again

Format and Install (again)

Installing..

Installation failed - Input/Output error(5)

:(

I'm not sure what's going wrong here..

My laptop is soulless right now..

Badass scenario:

Professor: writes a loop to sum up first five numbers and asks the output.

Me: 500

Other random student: 15

Prof praises him.

He runs the code.

Output: 500 ( internal server error)

(He had a missing semicolon) 😅

I had debug my perfectly working program.
Let me explain.
I wrote a python perform some calculations and return the result. In case the calculations were not successful, it would raise an error.
For some reason, it worked on all test cases: gave correct output with correct inputs and raised errors on non correct inputs but when I used it with another function, it just failed.
Turns out I had written 'return myExcetion' instead of 'raise my exception'.
Lol, I was almost gonna give up programming

Funny story...
Got a small college assignment based on Java and Cassandra(database). The database shell was running fine. Spent 5 days removing the random java exceptions and working on the basic connectivity, searched everywhere on Stack overflow and other forums for solutions and still no help.
So, I decided to write a program that would print only the output as I knew what would be the output when it will run. Took a screenshot of it and made up a cover story to tell my professor that I did it on a friend's computer.
But while I was taking a screenshot of the Eclipse with code window and output window, some random syntax errors popped up.(but they weren't syntax error).
So I created a new project and copied the pom.xml file and the code into the new one(I tried this one before and it didn't work). And there were no errors. So I took a screenshot of it with output of different file and opened a different file.

But then, don't know what came across my mind and I clicked on run just to see if this works, and it worked fine. And now I'm like.. WTF JUST HAPPENED!!

I've already ranted about this, the hdd randomly broke over night. I was (i shit you not) just about to set up backups for it this day.

Being relatively new to linux but confident with bash and cli and stuff.. reading "I/O Error" as output of nearly any command on a server rented somewhere 150 km away from me was like a punch in the face.:D

It wasn't directly bad, but it was kinda sad, I had a (now don't laugh - a man gotta chill from time to time) minecraft server running there with tons of mods and we were multiple 100s of hours into it already..
But not only that, my projects weren't on any git or anything anymore (local copies were gone, guess what gitlab i set up proudly i used..) and there was no recovering these little loved ones, together with my website.

It was a black day, my group i had to work with in university doubted me because for them i wasn't able to manage a git server properly and i hope it does not happen again..):

Bootcamps get you up and running in coding quickly. If you are a programmer, companies are only interested on how quickly, error free and cheaply you produce marketable output. Bootcamps enable this.

More or less you are not more than a former assembly line worker putting parts on a car platform. Your value is not very high as you may be exchanged at any time at their will.

Nevertheless, you can earn money quickly. You trade in your youth and time which might be a dead end in the long-term. Trends go to machine learning, artificial intelligence. They will not need Bootcamp people and code workers.

It is better you set up Bootcamps and sell them versus absolving this. Like selling shovels during the gold rush, but not working in the mud of Alaska by yourself.

Your choice is: Making quick money, which fades anyway; or striving for the long-term future proof career.

C/S degrees from Technical Universities of reputation give to you the right direction under a strategic consideration. Companies which pay well, or freelancing with a solid acknowledged background, will always look for top graduates. People from Bootcamps are just OK for hammering assembly line coding. Even worse with SCRUM in one noisy room under enormous team server pressure controls, counting your lines of code per minute, with pale people all around. And groups of controllers never acknowledging nor trusting your work.

To acquire a serious degree, a Bachelor is nothing. Here, in INDIA, Bachelor now is what a former high school grade was. You must carry a diploma or Masters degree combined with internships at big companies with high brand recognition. This will require 4–6 years of your lifetime. You can support this financially by working part-time freelancing as making some projects front- or back-end web, data analysis and else.

Bootcamp people will lose in the long-term. They are the modern cannon fudder of software production.

It is your choice. Personally, I would never do Bootcamps. Quality and sustainability require time, deep studies and devotion.

Started writing a parser for moonscript. Because I want to do my own syntax highlighting and error support.

I'm sorry, but was this supposed to difficult? Every article I read claimed this was gonna be some impossible feat of herculean effort. I half dreaded it, the other half was kinda elated.

Only it didnt live up to the hype. The tokenizer is a glorified character stream. The lexer is little more than a tokenizer, and the "most complicated" bit is nothing but a fancy transformation of the token output into a tree.

I'm completely to new parsers proper and semantic checking and maybe that's why it seemed easy, but I dont see what all the forewarning in tutorials were ever about.

So, started working in a nodejs/react personal project with an old friend. I code in linux mint, my pal always at windows 7 never worked in something different from php. From the very beginning I advised him to move to linux

Me: hey man, the backend is running now, pull the changes and `npm start`

Friend: ok so I need to install dependencies right?
Me: yup, easy peasy lemon squeezy

So after a brief(one week period) until my friend could install visual studio to get some deps installed

Friend: hey I ran `npm start`, it got stuck. backend does not start at all, no output messages, no error, no nothing

Me: FFS, that's why I told you from the start, "use any linux distro for this project" :(

Then for a couple of hours(4) trying to install a distro in his 7 years old laptop...

Me: Ok, let's call it a day, 7 tries to install this thing in your old machine is enough. did you not realize your HDD was really busted? in your 7 years with your laptop? this is BS that's why I could not install linux :|

Friend: I didn't, windows never showed me any problem, maybe windows is better than linux in that matter.

Me: GTFO

Very excited, got my raspberry pi zero working over usb finally, gotta admit it took me a while to figure it out that the ifconfig IP assigned to the interface established isn't actually the raspberry pi's (seriously you don't want to see how far the visited google links go for all variations of "how to setup the otg ssh connection"), that only came to me once I was able to find the mini-hdmi to hdmi cable, before that it was a pure shitfest:

First I just tried all sort of configs, but the raspberry pi kept denying the ssh connection, slammed the microsd into my bigger Pi, even multiple times ran raspi-config, forced ssh to start in all possible ways, nothing.

Then I tried to use the TV-output on it together with my old small portable tv to maybe see some error-logs or the ssh not starting on the zero for whatever reason, even flashed a 2016 image thinking it is stretchs fault for not working, but then my fucking soldering iron cable disappeared, tried to quickly create my own, but that failed cause the 3.5mm connector it uses is different from the ones I had available, so I macgyvered a sketchy ass lose connection with male headers sticking through from the bottom and being sticked against the board with a female end on top, but the TV output wouldn't work, even with proper config options, so I gave up.

Some days later I've found the cable, connected it and realized the fucking IP it gets assigned is totally different from the interface, well fuck my life.

Atleast now I can make a clean image of that microSD and setup the portable laravel development raspi as I wanted, can't wait to try it once I get more time to fully set it up - btw even the internet bridge worked right out of the box, so I can easily use my laptops internet connection on the zero.

Let me start this off by stating I'm a Java dev, and a noob with C++.

Thought it'd be cool to learn some OpenCL, since I want to do some maths stuff and why not learn something new.

So I sat down, installed Nvidia proprietary drivers, broke my x-org server, purged, reinstalled, rebooted and after a while I got stuff sorted out.

Then on to my IDE. I use CLion and it uses Cmake. C++ noob knows shit about Cmake, so struggle for two hours trying to figure out wtf is going on with the OpenCL libs and why they're only partially detected. Fml.

Finally, everything is configured and I'm set. I start working on a Hello World program using OpenCL. Finish it in 20 mins, all good. No output. Do some googling, check my program a million times. Nothing wrong here. Check the kernel, everything as in the tutorial.

I start checking error codes after a while reported by OpenCL (which I had no clue was a thing) and I get some code saying the program was not created properly (to run the kernel). No fucking clue what's up with that. Google around, find another tutorial, rewrite my code in case I'm using outdated code or something. Nothing.

Fast forward an hour, I find out that OpenCL has logs! So I grab some code from the website I found it on, and voila, I finally get some info on what's going on.

Get a load of this bs.

In the kernel file, so that OpenCL knows that it's a function to run, you have to put __kernel. But in all the places I read, it said to put it as _kernel.

Add the underscore, compile, run and everything is perfect.

Then I tried just putting 'kernel'. Also compiles and runs fine.

Two hours hours and my program was fixed by adding an underscore. IF ONLY C++ GAVE AN INDICATION OF WHAT BLEW UP INSTEAD OF SITTING BACK AND BEING LIKE "oh wow man feels bad, work some magic and try again" THEN THIS WOULD NOT HAVE TAKEN SO LONG.

Then again, it was OpenCL that was being shitty with its styling enforcement or whatever the hell the underscore business is. But screw it. C++ eats shit too for this. Sure, maybe Java babies you by giving you the exact error and position that the error took place at. But at least that way you don't waste hours of your life chasing invisible bugs 😠😠

I'm going to eat some food... Too much energy was consumed fighting the system... Then I'll get back to OpenCL because 😇 but that doesn't make it less bs.

I had to build a few packages today from a git source.

Everything just plain text or shell scripts - so no fancy shit, no buildsystem... Nothing.

I was painfully reminded why I had forgotten a lot about dpkg package builds.

Fun facts:
- seems like impossibro to define an output directory for debuild (../ from source which must be pwd/cwd)
- i used /opt/<vendor_name>... Purging the deb from system deletes opt too, as it is empty
- reprepro (or whateva it is called) fails with an "uncommon GPG error" instead of saying "I don't know which key to use"
- creating rolling release numbers (as the packages won't have a real versioning system...) is fun - when you remember that date isn't sufficient, as the time part is necessary to build multiple packages (versions) per day

Compared to an Gentoo ebuild, this was really rocket science....

Guess as soon as someone does not follow the debian way, he must be shunned and exiled. At least it felt like this ....

But it works now. Woohoo. *cries internally*

This error, which took me a long time to find, demonstrates the importance of useful variable names.

Using the Wolfram Language:

pp = {};
For[i = 0, i <= Max[p], i++, If[Count[p, i] != 0, pp = Join[pp, {{i, Count[pp, i]}}], -1]];
pp

Outputs:

{{1, 0}, {2, 0}, {3, 0}, {4, 0}, {5, 0}, {6, 0}, {7, 0}, {8, 0}, {9, 0}, {10, 0}, {11, 0}, {12, 0}, {13, 0}, {14, 0}, {15, 0}, {16, 0}, {17, 0}, {18, 0}, {19, 0}, {20, 0}, {21, 0}, {22, 0}, {23, 0}, {24, 0}, {25, 0}, {26, 0}, {27, 0}, {28, 0}, {29, 0}, {30, 0}, {31, 0}, {32, 0}, {33, 0}, {34, 0}, {35, 0}, {36, 0}, {37, 0}, {38, 0}, {39, 0}, {40, 0}, {41, 0}, {42, 0}, {43, 0}, {44, 0}, {45, 0}, {46, 0}, {47, 0}, {48, 0}, {49, 0}, {50, 0}, {51, 0}, {52, 0}, {53, 0}, {54, 0}, {55, 0}, {56, 0}, {57, 0}, {58, 0}, {59, 0}, {60, 0}, {61, 0}, {62, 0}, {63, 0}, {64, 0}, {65, 0}, {66, 0}, {67, 0}, {68, 0}, {69, 0}, {70, 0}, {71, 0}, {72, 0}, {73, 0}, {74, 0}, {75, 0}, {76, 0}, {77, 0}, {78, 0}, {79, 0}, {80, 0}, {81, 0}, {82, 0}, {83, 0}, {84, 0}, {85, 0}, {86, 0}, {87, 0}, {88, 0}, {89, 0}, {90, 0}, {91, 0}, {92, 0}, {93, 0}, {94, 0}, {95, 0}, {96, 0}, {97, 0}, {98, 0}, {99, 0}, {100, 0}, {101, 0}, {103, 0}, {104, 0}, {105, 0}, {106, 0}, {107, 0}, {108, 0}, {111, 0}, {112, 0}, {116, 0}, {118, 0}, {122, 0}, {125, 0}, {136, 0}, {137, 0}}

As opposed to the expected output, which should have no 0s as the second values in any of the tuples.

I spent a large amount of time examining the code to generate p before realizing that the bug was in this line.

Build failed: "CL.exe has exited with exit code 5"

Thank you Visual Studio for the detailed error report about why the build fails! I can finally fix it!

(This is not fixable by running VS as administrator, also the output file is not running nor locked by some process)

Some compilers give an error message on forgotten type casting. From that it shows good typing style casting. So you also avoid clerical errors that can lead to the program crash in the worst case. With some types it is also necessary to perform type casting comma on others Types, however, do this automatically for the compiler.
In short:Type casting is used to prevent mistakes.
An example of such an error would be:
#include <stdio.h>
#include <stdlib.h>
int main ()
{
int * ptr = malloc (10*sizeof (int))+1;
free(ptr-1);
return 0;
}

By default, one tries to access the second element of the requested memory. However, this is not possible, since pointer calculation (+,-) does not work for a void pointer.
The improved example would be:
int * ptr = ((int *) malloc (10*sizeof (int)))+1;

Here, typecasting is done beforehand and this turns the void pointer into its int pointer and pointer calculation can be applied. Note: If instead of error "no output" is displayed on the sololearn C compiler try another compiler.

Two days ago on my linux partition python was being weird, and I couldn't fix it no matter what I tried. Logical option was to backup /home and then reinstall linux

Two days later I want to die, for whatever reason I can't properly boot from a live USB without getting "input/output error", and I've already erased my previous linux installation at this point.

Anyway, I still have windows, and I think that the problem might be faulty RAM (I get i/o errors with any live USB) so I booted into windows, let it do some updates and now I'm checking my memory

After this, I'm going to open up my PC and check that the RAM sticks are all in properly

Finally finished an algo to check an image for grouping of pixels that will form a rectangular area. I got the grouping to work on one image, but found it was utterly failing on another. I went through every step of the algo and still could not find the solution. The 128x128 image was working, but the 128x16 image was not. I knew it had something to do with the dimensions. Started thinking it was overflowing a buffer somewhere. So I started putting asserts in the functions that abstracted the buffer access. None of the numbers exceeded the proper bounds. It was close to bedtime so I finally gave up. I was tired. Then I realized it wouldn't be until the next evening when I could look at this again. So I got up again and started looking at the code again. I had a loop to check the output of my algo that I did the memory access of the buffer. It too was not fully filling my temp image to show how the algo was working. WTF!

Then I finally realized the flaw:
buffer[x+y*height]

And my test loop to test the algo:
buffer[x+y*ymax]

I kept overlooking the error because I was sure it was right. Also my asserts for the functions to access the buffers? They only checked the inputs x and y. So it didn't help that the math was wrong for reading and writing the buffers. It also worked fine on 128x128 images because the width and height were the same.

It is funny that I struggled with this part. The algo was actually surprisingly easy to formulate. I just looked through every point and checked a buffer to see if that point was used. If not then I would attempt to grow in the x and y direction the shaped of that point based upon pixel color. This was saved in a structure while growing that point. Then when that rectangle could not be grown further the inner loop would continue checking used points again.

I still have work to do to use the data this algo produces. I need to now figure out how to parent the rectangular areas to each other. I will probably use my check buffer to keep track of these rects by an index. Then do adjacent checks to determine parenting. Eventually I will have to extend this algo to 3 dimensions, but that should not be difficult.

Other build tools:

Here is a plugin, use it . Be done.

Scala Build Tool aka SBT:

Build your own plugin.

Everything is scala...
You can create by the way funny endless loops when using the wrong syntax - yet it might compile successfully. And then when you load the plugin, it works. Till it is evaluated - lazy evaluation for the fun.

Error messages are at best cryptic.

*If* you manage to get a working plugin and *if* it runs...

Surprise. Surprise.

You might need to parse the log output of SBT.

Another funny surprise: Log output isn't configurable. You can configure the log level. That's it.

So after a lot of pain stakingly putting together a fucking shitty plugin, you can now grind the rest of your brain with ...
sed.

Cause yeah. You can now use regex to parse an sbt build log and extract the necessary information.

:)

...

So....

Are we there?

Mwahahahhaa.

Only if you haven't forgotten to either disable colored output for SBT... Or take an extra mile with e.g. less -R.

Otherwise you have ASCII control characters in your file. :-)

After getting that shit to work, you now have finally a parseable build log.

Just took days instead of hours.

But that's SBT. :-)

I picked a module of my nodejs app which uses MongoDB to pieces until I had no more idea what could be wrong. It should work. There could be nothing wrong. Then I thought: "What if I try to find() from the wrong collection?" Yes. Fucking YES! I've lost about 2 hours of my life because I've written the collection name in singular rather then plural. Just a fucking single character. Just a fucking "s"! Why don't you output an error? Why? Fuck you! Why don't you do that?

Today is thursday. Oh no.

At thursdays I have a 8h30-19 schedule (I have 1h30' of free time to go home and cry after I finish a class at 15h30 though) and there's this one class I DREAD. It's a 2h class at 17h and it's an exercise class. This wouldn't be so bad it I actually understood the code behind the exercises, because they don't teach us code in the theory classes (btw it's C. I hate that language because of all this). The teacher pretty much tells us "do this exercise", waits like 10' and then starts to (try to) explain what we're supposed to do. Oh my god.
The other day he was like "write "exec ( ... "text" ... )", compile and execute". It didn't work. Of course it didn't why would it? I was switching around between terminal, manual and text editor, to no avail. In the end he explained but I don't think I got it.
Every time I think about this class I die a little inside and start to become somewhat anxious to be honest. The theory is not that that hard, the practice part is what is killing me (I have test in 2w but I'm just gonna start studying earlier so I can go watch this match LoL).
Does someone know a good book (preferably online, if possible) or a good website on C? I really need to read that, that language is killing me.

Bonus: the other day I had to do a homework that was to be delivered. We had to write a program that read the program and its arguments like this:

./program_name
numArgs
arg1
arg2
etc

I wrote the code, had some bumps in the way, asked a colleague for help because we needed to have a custom function made that was to be done in the class but that I couldn't make because of the reasons above. Then it came the time to test. My VM broke (I think I'm gonna format my PC to try to fix that. Have installed some other versions of the VM but the installations fails or the machine doesn't start) so I sent it to said colleague to test. She said it did OK and so I sent the work to this website we have to send our works to.
"2 errors".
What? What happened? She said it worked just fine.
Looked at my code, couldn't see anything wrong.
Asked the same colleague for help.
Turns out I missed a space. A SPACE. I don't think I've ever felt so frustrated in my life. A presentation error in Java is a good thing, at least we know the program works fine, it's just the output that's wrongly formatted. But C? Nope, errors all around, oh my god. I'm still mad about it.
And I owe her a chocolate.

OUTPUT:

Spent last 2 days trying to get an upstream data file loaded. I've now concluded it's just corrupted during transfer beyond repair... But I got to practice lots of Linux commands trying to figure out what the issue was and fix it (xml parser was throwing some error about nulls originally)

vi, grep, head, tail, sed, tr, wc, nohup, gzip, gunzip, input output redirection

I give up. I am having trouble understanding Go lang *, & stuff.
attached code does print what fmt.Println has, but the function calling: FindByID is throwing invalid memory address or nil pointer when it attempts to use the result of the code.

Can someone please explain where I'm wrong?
Error log blames the line of "if" condition even though fmt does print its output to console

No proper normalization and database structure practices seems to continue to be the bane of my fucking existence at work.

One would think that it would be the quirks carried through by the language stacks in question, those are fucking absolutely ridiculously horrible by the way, y'all think you've seen bad Javascript and PHP? these would make you cry, laugh, wonder in amazement and then fucking pity me and eventually buy me a beer NO JOKE.

Y'all think you have seen some obscenely unoptimized SQL code? think of the worst fucking possible output from the shitty-est most error prone boundary checking inefficient ORM out there and multiply it by 10k. Then refer to my other point, and do the same thing for me which culminates in alcoholic consumption.

Worst thing? the developer that wrote most of this is a college level TEACHER rn....i've met the smug piece of shit, he acted severely condescending to everyone around him and I just smiled because I know how much of a piece of shit he is.

The other dude in question (it was two of them that I am talking about) left for another city and currently holds a senior developer position....i-fucking-magine that.

Fuck I hate these mfkers and I really wish they gave me a chance to fucking blow up on them.

So at the HS I go to, there are 4~5 programmers (only 3 real "experienced" ones though including me).

So coming from JS & Python, I hate Java (especially for robotics) and prefer C++ (through some basic tutorials).

Programmer Nº2 is great at everything, loves Objective-C, Swift, Python, and to a certain extent Java.

Programmer Nº3 loves Python and used to do lots of C#, dislikes Java and appreciates Go (not much experience).

So naturally I get shit on (playfully) because of my JS background, because they don't understand many aspects of it. They hate the DOM manipulation (which is dislike too tbh), but especially OOP in JS, string/int manipulation, certain methods and HOISTING.

So, IDK if Java or C++ (super limited in them) have hoisting, but if you don't know what hoisting is, it means that you can define a variable, use it before assigning a value, and the code will still run. It also means that you can use a variable before defining it and assigning a value to it.

So in JS you can define a variable, assign no value to it, use it in a function for instance, and then assign a value after calling the function, like so:

var y;
function hi(x) {
console.log(y + " " + x);
y = "hi";
}
hi("bob");

output: undefined bob

And, as said before, you can use a variable before defining it - without causing any errors.
Since I can barely express myself, here is an example:
JS code:

function hi(x) {
console.log(y + " " + x);
var y = "hi";
}
hi("bob");

output: undefined bob

So my friends are like: WTF?? Doesn't that produce an Error of some sort?
- Well no kiddo, it might not make sense to you, and you can trash talk JS and its architecture all you want, but this somehow, sometimes IS useful.

No real point/punchline to this story, but it makes me laugh (internally), and since I really want to say it and my family is shit with computers, I posted it here.

I know many of you hate JS BTW, so I'm prepared to get trashed/downvoted back to the Earth's crust like a StackOverflow question.

WHO CAN SPOT THIS STUPID PHP ERROR!

$string = "something.com"

if(strpos(".", $string))
echo " yep, there's a period";
else
echo "nope, fuck you there isn't";

output: "nope, fuck you there isn't"

me: wtf ??? fucking wasting my time on this fucking stupid tiny fucking error, goddamnit and each refresh takes 15 seconds because it involves calling all these apis from localhost, gmail, etc. arggg...

...for an hour, until I smacked my head so hard I'm in the hospital for a concussion

I hate when that happens.

Time to take a break.

I finally got the lstm to a training and validation loss of < 0.05 for predicting the digits of a semiprime's factors.

I used selu activation with lecun normal initialization on a dense decoder, and compiled the model with Adam as the optimizer using mean squared error.

Selu is self-normalizing, meaning it tends to mean 0 and preserves a standard deviation of one, so it eliminates the exploding/vanishing gradient problem. And I can get away with this specifically because selu *only* works on dense layers.

I chose Adam, even though this isn't a spare problem, because Adam excels on noisy problems and non-stationary objectives (definitely this), and because adam typically doesn't require a lot of hyperparameter tuning its ideal here, especially considering because I don't know what the hyperparameters should be to begin with.

I did work out some general guidelines on training quantity vs validation, etc.
The initial set wasn't huge or anything, roughly 110k pairs for training.

It converged pretty quick all things considered, and to the low loss like I mentioned, but even then the system always outputs the same result, regardless of the input, so obviously I'm doing something incorrectly.

The effectiveness of this approach for training and validation makes me question if I haven't got something wildly wrong. Still exploring though and figuring out how to get my answers back out. I'm hoping I just fucked up the output, and not the input as well.

My work product: Or why I learned to get twitchy around Java...

I maintain a Java based test system, that tests a raster image processor. The client is a Java swing project that contains CORBA bindings to the internal API of the raster image processor. It also has custom written UI elements and duplicated functionality that became available in later versions of Java, but because some of the third party tools we use don't work with later versions of Java for some reason, it's not possible to upgrade Java to gain things as simple as recursive directory deletion, yes the version of Java we have to use does not support something as simple as that and custom code had to be written to support it.

Because of the requirement to build the API bindings along with the client the whole application must be built with the raster image processor build chain, which is a heavily customised jam build system. So an ant task calls out to execute a jam task and jam does about 90% of the heavy lifting.

In addition to the Java code there's code for interpreting PostScript files, as these can be used to alter the behaviour of the raster image processor during testing.

As if that weren't enough, there's a beanshell interface to allow users to script the test system, but none of the users know Java well enough to feel confident writing interpreted Java scripts (and that's too close to JavaScript for my comfort). I once tried swapping this out for the Rhino JavaScript interpreter and got all the verbal support in the world but no developer time to design an API that'd work for all the departments.

The server isn't much better though. It's a tomcat based application that was written by someone who had never built a tomcat application before, or any web application for that matter and uses raw SQL strings instead of an orm, it doesn't use MVC in any way, and insane amount of functionality is dumped into the jsp files.

It too interacts with a raster image processor to create difference masks of the output, running PostScript as needed. It spawns off multiple threads and can spend days processing hundreds of gigabytes of image output (depending on the size of the tests).

We're stuck on Tomcat seven because we can't upgrade beyond Java 6, which brings a whole manner of security issues, but that eager little Java updated will break the tool chain if it gets its way.

Between these two components we have the Java RMI server (sometimes) working to help generate image data on the client side before all images are pulled across a UNC network path onto the server that processes test jobs (in PDF format), by reading into the xref table of said PDF, finding the embedded image data (for our server consumed test files are just flate encoded TIFF files wrapped around just enough PDF to make them valid) and uses a tool to create a difference mask of two images.

This tool is very error prone, it can't difference images of different sizes, colour spaces, orientations or pixel depths, but it's the best we have.

The tool is installed in both the client and server if the client can generate images it'll query from the server which ones it needs to and if it can't the server will use the tool itself.

Our shells have custom profiles for linking to a whole manner of third party tools and libraries, including a link to visual studio 2005 (more indirectly related build dependencies), the whole profile has to ensure that absolutely no operating system pollution gets into the shell, most of our apps are installed in our home directories and we have to ensure our paths are correct for every single application we add.

And... Fucking and!

Most of the tools are stored as source bundles in a version control system... Not got or mercurial, not perforce or svn, not even CVS... They use a custom built version control system that is built on top of RCS, it keeps a central database of locked files (using soft and hard locks along with write protecting the files in the file system) to ensure users can't get merge conflicts by preventing other users from writing to the files at all.

Branching is heavy weight and can take the best part of a day to create a new branch and populate the history.

Gathering the tools alone to build the Dev environment to build my project takes the best part of a week.

What should be a joy come hardware refresh year becomes a curse ("Well fuck, now I loose a week spending it setting up the Dev environment on ANOTHER machine").

Needless to say, I enjoy NOT working with Java. A lot of this isn't Javas fault, but there's a lot of things that Java (specifically the Java 6 version we're stuck on) does not make easy.

This is why I prefer to build my web apps in python or node, hell, I'd even take Lua... Just... Compiling web pages into executable Java classes, why? I mean I understand the implementation of how this happens, but why did my predecessor have to choose this? Why?

All i wanted was a toolbaritem which i can hide depending on a propery in my viewmodel (xamarin forms). that shithead does not have a damn IsVisible property so i had to make some custom shit for this. Result is that my page does not load anymore. no fucking error visible in output window.

could not resolve a bug in time as i have to pick up my girlfriend and do some social shit.

now i am on the road. all i can think of is getting back to my pc and fix this.

When your lint tool has an off by one error in its output window hiding a single issue from view.

php being php...
Complaining about "header already sent". I wonder why.
Solution: no permission to chmod the file system, thus printing an error to the output. That error provokes freezing the header, thus the header cannot be written anymore...

*cheers*

TypeScript types are fun. Problem is: the check is compile-time only.

I just wasted an hour not understanding that an integer passed from command line was actually getting transmitted as a string. The library, where that value landed as parameter, happily ignored the non-matching type and worked as if the value has not been set at all!

Dear library maintainer, please enforce your parameter types! Throw an error right into my face saying I shall not pass anything but an integer! Don't just continue to work to produce false output correctly. Thank you!

Dear TypeScript, I really want type checks on runtime.

Dear JavaScript: Why did you ever think loose types were a good idea? (And I say that as a PHP developer as well.)

So fun fact! The Rust macro error

"Macro expansion ignores <token> and everything after it"

does NOT mean that macro expansion on general ignores this token. What it DOES mean is that the macro expanded to something, then the parser was invoked, and the parser stopped consuming tokens at the specified point.

In normal human speak, this means
"This token is invalid in its context after macro expansion. Refer to the generated code for concrete error."

I spent hours moving intermediate results into macro parameters because I thought the error meant that your macro cannot expand to the second half of a comma-separated list or whatever, until I got the same message about '(' which is very obviously permitted macro output and doesn't even really make sense given that it's not a token.

Love this kind of humor, coworkers output into a log on errors begins with "Found Unidentified Critical Keyerror". Took a while before I noticed the genius message in this error! My colleague deserves a cookie!

Do reports actually make people dumber?

I write a lot of reports that output for our customers into excel. I'm starting to suspect that for many customers it doesn't actually help them, rather it might actually hurt them (also eat all my time).

If a user generates their own report via search options or etc to pull out some data, they usually SEEM to have put some thought into the actions required to find the data they want.

Accordingly:

1. They immediately know what information is there, and why some information might be excluded.

2. They can do a little trial and error to solve their own problems / better understand what is going on.

3. They're a hell of a lot less likely to insist that something is "MISSING!!!" without seeming to actually know what the thing(s) are that are missing.

With auto generated spreadsheet that shows up in the email there's just little no critical thinking outside of some stray thoughts in their head when the spreadsheet showed up ...

Fuck Threads and fuck multithreading in general.
I've spent the last 2 hours and a half looking for an important error that did my project not work at first execution, and it was all because I did start a side Thread, but forgot to wait until it was done before showing the output of it.

Fucking multithreading...

So, do any of your poor fuckers have the opportunity - nay, PRIVILEGE of using the absolute clusterfuck piece of shit known as SQL Server Integration Services?

Why do I keep seeing articles about how "powerful" and "fast" it is? Why do people recommend it? Why do some think it's easy to use - or even useful?

It can't report an error to save its life. It's logging is fucked. It's not just that it swallows all exceptions and gives unhelpful error messages with no debugging information attached, its logging API is also fucked. For example, depending on where you want to log a message - it's a totally different API, with a billion parameters most of which you need to supply "-1" or "null" to just to get it do FUCKING DO SOMETHING. Also - you'll only see those messages if you run the job within the context of SQL FUCKING SERVER - good luck developing on your ACTUAL FUCKING MACHINE.

So apart from shitty logging, it has inherited Microsoft's insane need to make everything STATICALLY GODDAMN TYPED. For EVERY FUCKING COMPONENT you need to define the output fields, types and lengths - like this is 1994. Are you consuming a dynamic data structure, perhaps some EAV thing from a sales system? FUCK YOU. Oh - and you can't use any of the advances in .NET in the last 10 years - mainly, NuGet and modern C# language features.

Using a modern C# language feature REMOVES THE ABILITY TO FUCKING DEBUG ANYTHING. THE FUCKER WILL NOT STOP ON YOUR BREAKPOINTS. In addition - need a JSON parsing library? Want to import a SDK specific to what you're doing? Want to use a 3rd party date library? WELL FUCK YOU. YOU HAVE TO INDEPENDENTLY INSTALL THE ASSEMBLIES INTO THE GAC AND MAKE IT CONSISTENT ACROSS ALL YOUR ENVIRONMENTS.

While i'm at it - need to connect to anything? FUCK YOU, WE ONLY INCLUDE THE MOST BASIC DATABASE CONNECTORS. Need to transform anything? FUCK YOU, WRITE A SCRIPT TASK. Ok, i'd like to write a script task please. FUCK YOU IM GOING TO PAUSE FOR THE NEXT 10 MINUTES WHILE I FIRE UP A WHOLE FUCKING NEW INSTANCE OF VISUAL STUDIO JUST TO EDIT THE FUCKING SCRIPT. Heaven forbid you forget to click the "stop" button after running the package and open the script. Those changes you just made? HAHA FUCK YOU I DISCARDED THEM.

I honestly cant understand why anyone uses this shit. I guess I shouldn't really expect anything less from Microsoft - all of their products are average as fuck.

Why do I use this shit? I work for a bunch of fucks that are so far entrenched in Microsoft technologies that they literally cannot see outside of them (and indeed don't want to - because even a cursory look would force them to conclude that they fucked up, and if you're a manager thats something you can never do).

Ok, rant over. Also fuck you SSIS

Me, taking a coding class in uni:
Purposely cramping everything in as few lines as possible, making the code barely readable, just to screw with the guy who had to correct this mess.
In my defence, the assignment they gave us was garbage. The task descriptions were often ambiguous or even contradictory to what actually was the case ("The InputStream will contain a string of csv data, each element starts in the next line" -> was a malformed single line string) and the automated tests they wrote to check our output where either completely unhelpful because of their meaningless error messages, or sometimes even plain wrong, telling us our output was wrong, even though it definitely wasn't.

Please help me!

today my friend wanted to publish his swift 3 library in cocoapods, set up proper github repository, made a releass/tag then tried to upload cocoa pods. first was success but somehow it turned out to be empty then we changed some settings in cocoapods (moved paths etc) then it started to give errors and such. strangely every fkin time different kind of error.
first realized he is using xcode 7 build tools which lacks support of swift3, then switchex to xcode8-beta tools but again that shit wasnt working. so i noticed that their app switching repo origin to their specs origin.
removed cocoapods from sys entirely, xcode7 as same as cocoapods and installed git cmd tools from homebrew to make it updated. started from scratch same shit also happened.

so i give up and fired chrome to look up issue, it turns out it was problem with xcode-beta and cocoapods entirely, even somebody just 30mins before us also commented on issue with exact same output problems
5hrs for shitty bugs fml...

What the ****? I added a call to one method, how the hell it could broke it so badly?

> Compile failed with 1163 errors; see the compiler error output for details.

Currently I have to devop a Verilog Module. Somehow there seems to be a bug in my environment and once I start the compile process this fucking compiler hangs for a solid 30 minutes or longer and I don't even get an output. It just stops with an Error that says I shall check the logfile, but it is empty.

Not really most painful, but definitely most painful of the recent bunch..
// yup, a bunch.. I've managed to fuck up a little on every thing I did that day :/ little friday the 13th for me, especially as I went on sick leave the next day and had to fixup my fuckups with a friggin migrane..

Anyways, I was fixing fallback to some default value in plsql.. before it didn't check what the input format was and simply relied on certain format, parsed that and converted to number..threw an error, duh!

I fixed it somehow elegantly to check with regex if the format is as expected and if not default to xy value..and if format is as expected to parse out the number..except that when I copied (or typed?! for the sake of me, I cannot recall how the fuck I managed to fuck this up) over the code to the package I didn't see additional [ at the begining, so everything went to the default.. Most embarrassing part is I commented everything, how it should work, use cases, what the input was and what was expected output..and failed to see the friggin extra [..
It was fixed easily, the extra [ stood out later when I saw the code, but it bothers me how I managed to overlook that in the first place. I think I need a vacation.. but have to fix other fuckups first.. :/

The more I learn about Spring... It feels like it just hides complexity.... And thus allows developers to make their apps more complex?

I can imagine there will be a Component class with like 20 references to other components either directly or indirectly... But then when something crashes or some error in output data is noticed in prod for some reason...

You cant tell exactly what cause the error because the objects' state is so complex, not sure which component or combination actually causes the issue.

Essentially makes a lot of black boxes?

*me trying to fix the preview issue by editing layout file*
*issue gets fixed by clean build*
*me implementing a new feature as per plan*
*suddenly another issue occurs with the items in recycler view*
*tries SO, no related question and me too scared to ask one*
*trying different names, keywords, ids and methods to get atleast some output*
*checks json and recycler adapter, all fine but still the error*
*hello darkness my old friend*
*checks the item layout again with a microscopic look and encounters a 0 added to layout width which makes 95dp to 950dp and hence no output somehow*
*2 hours and sunday mood wasted*

I spent 2-3 days on debugging code written in assembly script. Apparently, you need to initialise an array using new method otherwise it re-uses the previous array from the same scope and it has created infinitely large array. Just wtf.
And I got error like "wasm blah blah blah blah blah blah".Just give proper error.

Running the environment locally wasn't an option because well it doesn't fucking work locally. So, I have to forcibly test on CI and they have created a site that can show you logs because you can't access or query data directly from server and while debugging you try to log something it randomly works sometimes and sometimes you get output from god knows which deployment. Just create a fucking API for displaying log or build a proper docker so that we test it locally.

Testing the output for an image using a screenshot of an error message and then wondering why the output shows an error :/

Hey DevRant Fam!, hope everyone is very well,I just started using exercism with python inside my chosen editor Emacs, and well... the first problem i'm doing is the Hello World problem...

So the code i have is here:

def hello(name='world!'):
return "Hello, {0}".format(name)
hello()

and it prints out the output "Hello,World!"
but i'm getting a strange error in my command prompt saying something like this '1 Failed Assertion error None != 'Hello, World!'
anyone have some advice its my first time working with Exercism :-) cheers!

Thank you :-)

I'm beginning to feel like any kind of specific approximation via neural networks is a myth. That if you can't reduce output to simple categorical values that can be broadly interpreted between two points, that it doesn't work.

I have some questions and they don't seem to be getting answered about the design of the net. How many layers should I use ? How many neurons per layer ? How does this relate to the number of desired quantitive scalar outputs I'm looking to create, even if they are normalized, they can vary GREATLY and will if I'm approximating the out of several mathematical expressions. Based on this and the expected error ranges of these numbers and how many possible major digits could be produced within the domain of the variable inputs being introduced, how many neurons per layer ? What does having more layers do ? In pytorch there don't seem to be a lot of layer types per say, but there are a crap ton of activation functions, and should I just be using these at the tail end or should they actually be inserted between layers so the input of the next layer passes through another series of actiavtion functions ? what does this do to the range of output ?

do I need to be a mathematician to do this ?

remembered successes removed quantifiable scalars entirely from output, meaning that I could interpret successful results from ranges of decimal points.

but i've had no success with actual multi variable regression as of yet, even when those input variables are only 2 and on limited value ranges eg [0,100] and [0, 2pi]

and then there are training epochs to avoid overfitting, and reasonable expectation of batches till quality results will start to form.

I love linux because i dont have to forced to do frickin update like windows did.
Because i have an experience after update linux mint i cant even start the main GUI program. After boot only show blank console. It seem linux update broke the compatibility between my graphics card.
At least now i dont have to update because thats an option. The output of update is not different than windows.there is a chance you broke your OS.
But the struggle is when i need to install new app in linux. Sometimes need more than hour to find out why it doesnt work from the first time.
Any help here?
So this start from the office. In the office i usually use low spec laptop that work slowly. Then i found this IDE called rapidclipse. Its very promising with GUI builder and can build cross platform mobile app using only java built on top vaadin framework.
When i use it on low spec laptop hackintosh at office it work well although it take more time than other kind of eclipse and i dont need to install any kind of app again, just download-install-create new project-run on tomcat-work well.
Then i go to home to try this new tool , IMO my low spec PC still have more power to run something than old hackintosh. Because usually i use android studio with no problem. In the old hackintosh it went too long to build gradle only.
Then i install rapidclipse, then run desktop shortcut. Then it said i need to install correct java to use correct JavaFX.
After search on SO they said i must install jdk from oracle.
Ok so i got openjdk in my linux.wtf what is the different idk but dont have time to find out.
I install jdk from oracle.
Than finally can open the rapidclipse.
Wow , this gonna be fun.
Then create new project. Just a new project.
So im waiting. I see the progress at 10%. But still no increment on that.
I switch to other app for several minutes.
Then when switched back th app still at 10% and now is at no responding state. So i force close.
After that open rapidclipse again.
The previous new project can be opened. Yay, i think.
But so many error there. Omg.
So i create new project again.
But, but, i just repeated the first error then close again then try it again for several time. But still same output.
After an hour, i give up.
But still, why , just why it work like this. No error or whatsoever.
Back later i have a problem like this on different app.
Idkwhy.

Why i got the message 'Input/Output Error" when mounting /dev/mmcblk0p2....
Nothing crashed till i just booted twice to enter different systems Android and MeeGo (via Ubiboot).And when i powered off my Android and tried to boot into MeeGo, it said "Boot OS/kernel selection failed! \n Please run a maintance boot"

I already ran a maintance boot...
And i entered Ubiboot's Telnet (low battery), found that /dev/mmcblk0p2 failed to mount with an error "Input/Output error", but i dd'd this partition (copy data into a file), everything was fine...
And after that, my phone turned into blank...

So can anybody tell me how to fix this? It's not like a hardware problem, i think there's something wrong with the data in the partition, like the header...
