[long]
When searching for internship via school I found this small startup with this cute project of building a teaching tool for programming. There were back then 2 programmers: the founder and the co-founder.

Then like 1 week before the internship started, the co-founder had a burnout and had to get off the project, while the company was so low on budget the founder, aka my new b0ss, had to work separate jobs to keep the company alive. (quite metal tbh)

It's funny because I'm a junior developer, 100%. I've been coding as a hobby for around 8 years now but I've never worked in a big company before. (No exception to this workplace either)

First project I get: rewrite the compiler. The Python compiler.
"But wait, why not just embed a real compiler from the first case?"
-nanananana it's never simple, as you probably know from your own projects.

The new compiler, as compared to existing embedded compiler solutions out there, needed these prime features:
- Walk through the code (debugger style), but programmatically.
- Show custom exceptions (ex: "A colon is needed at the end of an if-statement" instead of "Syntax error line 3")
- Have a "Did-you-mean this variable?" error for usage of unassigned variables.
- Be able to be embedded in Unity's WebGL build target

All for the use case of being a friendly compiler.
The last dash in the list is actually the biggest bottleneck which excluded all existing open-source projects (i could find). Compliant with WebAssembly I can't use threads among other things, IL2CPP has lots of restrictions, Unity has some as well...

Oh and it should of course be built using test-driven development.

"Good luck!" - said the founder, first day of work as she then traveled to USA for **3 weeks**, leaving me solo with the to-be-made codebase and humongous list of requirements.

I just finished the 6th week of internship, boss has been at "HQ" for 3 weeks now, and I just hit the biggest milestone yet for this project.

Yes I've been succeeding! This project has gone so well, and I'm surprising myself how much code I've been pumping out during these weeks.

I'm up now at almost 40'000 lines of source and 30'000 lines of code. ‼
( Biggest project I've ever worked on previously was at 8'000 lines of code )

The milestone (that I finished today) was for loops! As been trying to showcase in the GIF.

---

It's such a giant project and I can honestly say I've done some good work here. Self-five. Over-performing is a thing.

The things that makes me shiver though is that most that use this application will never know the intricates of it's insides, and the brain work put into it.

The project is probably over-engineered. A lot. Having a home-made compiler gives us a lot of flexibility for our product as we're trying to make more of a "pedagogic IDE". But no matter that I reinvented the wheel for the 105Gth time, it's still the most fun I've had with a project to date.

Also btw if anyone wants to see source code, please give me good reasons as I'm actively trying to convince my boss to make the compiler open-source.

Cheers!

Did a bunch more cowboy coding today as I call it (coding in vi on production). Gather 'round kiddies, uncle Logan's got a story fer ya…

First things first, disclaimer: I'm no sysadmin. I respect sysadmins and the work they do, but I'm the first to admit my strengths definitely lie more in writing programs rather than running servers.

Anyhow, I recently inherited someone else's codebase (the story of my profession career, but I digress) and let me tell you this thing has amateur hour written all over it. It's written in PHP and JavaScript by a self-taught programmer who apparently discovered procedural programming and decided there was nothing left to learn and stopped there (no disrespect to self-taught programmers).

I could rant for days about the various problems this codebase has, but today I have a very specific story to tell. A story about errors and logs.

And it all started when I noticed the disk space on our server was gradually decreasing.

So today I logged onto our API server (Ubuntu running Apache/PHP) and did a df -h to check the disk space, and was surprised to see that it had noticeably decreased since the last time I'd checked when everything was running smoothly. But seeing as this server does not store any persistent customer data (we have a separate db server) and purely hosts the stateless API, it should NOT be consuming disk space over time at all.

The only thing I could think of was the logs, but the logs were very quiet, just the odd benign message that was fully expected. Just to be sure I did an ls -Sh to check the size of the logs, and while some of them were a little big, nothing over a few megs. Nothing to account for gigabytes of disk space gradually disappearing.

What could it be? I wondered.

cd ../..
du . | sort --sort=numeric

What's this? 2671132 K in some log folder buried in the api source code? I cd into it and it turns out there are separate PHP log files in there, split up by customer, so that each customer of ours (we have 120) has their own respective error log! (Why??)

Armed with this newfound piece of (still rather unbelievable) evidence I perform a mad scramble to search the codebase for where this extra logging is happening and sure enough I find a custom PHP error handler that is capturing (most) errors and redirecting them to these individualized log files.

Conveniently enough, not ALL errors were being absorbed though, so I still knew the main error_log was working (and any time I explicitly error_logged it would go there, so I was none the wiser that this other error-catching was even happening).

Needless to say I removed the code as quickly as I found it, tail -f'd the error_log and to my dismay it was being absolutely flooded with syntax errors, runtime PHP exceptions, warnings galore, and all sorts of other things.

My jaw almost hit the floor. I've been with this company for 6 months and had no idea these errors were even happening!

The sad thing was how easy to fix all the errors ended up being. Most of them were "undefined index" errors that could have been completely avoided with a simple isset() check, but instead ended up throwing an exception, nullifying any code that came after it.

Anyway kids, the moral of the story is don't split up your log files. It makes absolutely no sense and can end up obscuring easily fixable bugs for half a year or more!

Happy coding.

Spent most of the day researching some obscure exception being raised when trying to use installutil to install my custom windows service only to discover it worked just fine when I ran the command prompt as administrator 🙃🔫

Had an internet/network outage and the web site started logging thousands of errors and I see they purposely created a custom exception class just to avoid/get around our standard logging+data gathering (on SqlExceptions, we gather+log all the necessary details to Splunk so our DBAs can troubleshoot the problem).

If we didn't already know what the problem was, WTF would anyone do with 'There was a SQL exception, Query'? OK, what was the exception? A timeout? A syntax error? Value out of range? What was the target server? Which database? Our web developers live in a different world. I don't understand em.

firstly, does anyone know of an online telegram or whatsapp group where i can ask silly stuff regarding web dev and get immediate answers, just like it is here?

secondly i am trying to learn js and there are just too many related terms that are messing with my brain:
"some features are supported ines5/es6/es15/es16/es17 , some are supported in chrome's v8/chakra/spidermonkey/android browser , some features are only supported in "serverside" and blocked in all browsers thanks to browser's vm environment; babel can't read this code, some features are provided only by node js..."
WHAT THE MESS IS THIS?

All i am trying to do is to write code that would make a website visible to everyone. if by specific browser , i want to target, chrome and its subsidaries and android chrome/other android browsers .
for other browsers am willing to make external converters later but don't want to change my code by 1 bit. And from what i know, each browser (at least the browsers am thinking of supporting) has the complete JS compilers already built in

can i or can i not built a complete functional website with those things?

and finally my main question : how to make custom exceptions in vanilla js? i saw this answer on stack overflow:
===================
function InvalidArgumentException(message) {
this.message = message;
// Use V8's native method if available, otherwise fallback
if ("captureStackTrace" in Error)
Error.captureStackTrace(this, InvalidArgumentException);
else
this.stack = (new Error()).stack;
}

InvalidArgumentException.prototype = Object.create(Error.prototype);
InvalidArgumentException.prototype.name = "InvalidArgumentException";
InvalidArgumentException.prototype.constructor = InvalidArgumentException;

Usage:

throw new InvalidArgumentException();
var err = new InvalidArgumentException("Not yet...");

=====================================

where is the error code? what would be the exception details? what is the line number/timestamp of error?why is that function making an error, i thought error/exception is a class in JS?

So, I just (few hours ago)made a new variable that's either brilliant or innately flawed... not sure yet. It's an oddly unique var...

__bs__

So far I only made it in python and windows env (i script like the methodology of css).

I bet you're wondering how I've defined __bs__ and the practicality of it.
__bs__ is derived from a calculated level of bullshit that annoys me to tolerate, maintain, etc. as well as things that tend to throw nonsensical errors, py crap like changing my strings to ints at seemingly random times/events/cosmic alignments/etc or other things that have a history of pulling some bs, for known or unknown reasons.

How/why did this come about now?

Well I was updating some symlinks and scripts(ps1 and bat) cuz my hdd is so close to death I'm wondering if hdd ghosts exist as it's somehow still working (even ostream could tell it should be dead, by the sound alone).

A nonsense bug with powershell allowing itself to start/run custom ps1scripts with the originating command coming from a specific batch script, which worked fine before and nothing directly connected to it has changed.

I got annoyed so took an ironic break from it to work on python crap. Python has an innately high level of bs so i did need to add some extra calculations when defining if a py script or function is actually __bs__ or just py.

The current flavour of py bs was the datetime* module... making all of my scripts using datetime have matching import statements to avoid more bs.

I've kept a log of general bs per project/use case. It's more like a warning list... like when ive spent hours debugging something by it's traceback, meticulous... to eventually find out it had absolutely nothing to do with the exception listed. Also logged aliases i created, things that break or go boom if used in certain ways, packages that ive edited, etc.

The issue with my previous logging is that it's a log... id need to read it before doing anything, no matter how quick/simple it should be, or im bound to get annoyed with... bs.

So far i have it set to alert if __bs__ is above a certain int when i open something to edit. I can also check __bs__ fot what's causing the bs. I plan to turn it into a warning and recording system for how much bs i deal with and have historical data of personal performance vs bs tolerance. There's a few other applications i think ill want to use it for, assume it's not bs itself.

*in case you prefer sanity and haven't dealt with py and datetime enough, here's the jist:
If you were to search any major forum like StackOverflow for datetime use in py, youd find things like datetime.datetime.now() and datetime.now() both used, to get the same returned value. You'll also find tons of posts for help and trying to report 'bugs', way more than average. This is because the datetime package has a name conflict... with itself. It may have been a bug several years ago, but it beeb explicitly defined as intentional since.

Can the error types of my library depend on a custom library context object to be printable or otherwise meaningful? Pretty much everything else depends on this context, but until now the errors were an exception (no pun intended) because I wanted them to be printable by any handler that bumps into them, without scoping concerns. Now I tried removing them and like a third of my library has suddenly become context-free, because it only used the context to fully resolve everything before error reporting.

It's these individually tiny annoyances in products and software that together form a huge annoyance.

For example, it's 2022 and Chromium-based web browsers still interrupt an upload when hitting CTRL+S. This is why competition is important. If there was no Firefox, the only major web browsers would, without exception, have this annoyance, since they're all based on Chrmoium.

I remember Chromium for mobile formerly locking scrolling and zooming of the currently viewed page while the next page was loading. Thankfully, this annoyance was removed.

In 2016, the Samsung camera software was updated to show a "camera has been opened via quick launch" pop-up window when both front and rear sensors of the smartphone were covered while the camera was launched by pressing the home button twice, on the camera software Samsung bundled with their custom version of Android 6. What's more, if that pointless pop-up was closed by tapping the background instead of the tiny "OK" button or not responded to within five seconds, the camera software would exit itself. Needless to say, this defeats the purpose of a quick launch. It denies quick-launching while the phone is in the pocket, and the time necessary to get the phone out could cause moments to be missed.

Another bad camera behaviour Samsung introduced with the camera software bundled with their customized Android 6 was that if it was launched again shortly after exiting or switching to stand-by mode, it would also exit itself again within a few seconds. It could be that the camera app was initially designed around Android 5.0 in 2015 and then not properly adapted to Android 6.0, and some process management behaviour of Android 6.0 causes this behaviour. But whatever causes it, it is annoying and results in moments to not be captured.

Another such annoyance is that some home screen software for smartphones only allows access to its settings by holding a blank spot not occupied by a shortcut. However, if all home screen pages are full, one either needs to create a new page if allowed by the app, or temporarily remove a shortcut to be able to access the settings.

More examples are: Forced smartphone restart when replacing the SIM card, the minimum window size being far too large in some smartphones with multi-windowing functionality, accidental triggering of burst shot mode that can't be deactivated in the camera software, only showing the estimated number of remaining photos if less than 300 and thus a late warning, transition animations that are too slow, screenshots only being captured when holding a button combination for a second rather than immediately, the terminal emulator being inaccessible for the first three minutes after the smartphone has booted, and the sound from an online advertisement video causing pain from being much louder than the playing video.

Any of these annoyances might appear minor individually, but together, they form a major burden on everyday use. Therefore, developers should eliminate annoyances, no matter how minor they might seem.

The same also applies for missing features. The individual removal of a feature might not seem like a big of a deal, but removing dozens of small features accumulates to a significant lack of functionality, undermining the sense of being able to get work done with that product or software when that feature is unexpectedly needed. Examples for a products that pruned lots of functionality from its predecessor is the Samsung Galaxy S6, and newer laptops featuring very few USB ports. Web browsers have removed lots of features as well. Some features can be retrofitted with extensions, but they rely on a third-party developer maintaining compatibility. If many minor-seeming features are removed, users will repeatedly hit "sorry, this product/software can not do that anymore" moments.
