*me and a bored coworker
me: bored as hell dude.

him: i have a fun game in mind.

me: shoot.

him: *brings his keyboard
him: type the string you can type the fastest. we will time it. i will start.
him: *types his name
him: your turn.

me: Scanner scanner = new Scanner(System.in);

him: the fuck is wrong with you?

Worst fight I've had with a co-worker?

Had my share of 'disagreements', but one that seemed like it could have gone to blows was a developer, 'T', that tried to man-splain me how ADO.Net worked with SQLServer.

<T walks into our work area>
T: "Your solution is going to cause a lot of problems in SQLServer"
Me: "No, its not, your solution is worse. For performance, its better to use ADO.Net connection pooling."
T: "NO! Every single transaction is atomic! SQLServer will prioritize the operation thread, making the whole transaction faster than what you're trying to do."
<T goes on and on about threads, made up nonsense about priority queues, on and on>
Me: "No it won't, unless you change something in the connection string, ADO.Net will utilize connection pooling and use the same SPID, even if you explicitly call Close() on the connection. You are just wasting code thinking that works."

T walks over, stands over me (he's about 6.5", 300+ pounds), maybe 6 inches away

T: "I've been doing .net development for over 10 years. I know what I'm doing!"

I turn my chair to face him, look up, cross my arms.

Me: "I know I'm kinda new to this, but let me show you something ..."

<I threw together a C# console app, simple connect, get some data, close the connection>

Me: "I'll fire up SQLProfiler and we can see the actual connection SPID and when sql server closes the SPID....see....the connection to SQLServer is still has an active SPID after I called Close. When I exit the application, SQLServer will drop the SPD....tada...see?"
T: "Wha...what is that...SQLProfiler? Is that some kind of hacking tool? DBAs should know about that!"
Me: "It's part of the SQLServer client tools, its on everyone's machine, including yours."
T: "Doesn't prove a damn thing! I'm going to do my own experiment and prove my solution works."
Me: "Look forward to seeing what you come up with ... and you haven't been doing .net for 10 years. I was part of the team that reviewed your resume when you were hired. You're going to have to try that on someone else."

About 10 seconds later I hear him from across the room slam his keyboard on his desk.

100% sure he would have kicked my ass, but that day I let him know his bully tactics worked on some, but wouldn't work on me.

ARGH. I wrote a long rant containing a bunch of gems from the codebase at @work, and lost it.

I'll summarize the few I remember.

First, the cliche:
if (x == true) { return true; } else { return false; };
Seriously written (more than once) by the "legendary" devs themselves.

Then, lots of typos in constants (and methods, and comments, and ...) like:
SMD_AGENT_SHCEDULE_XYZ = '5-year-old-typo'

and gems like:

def hot_garbage
magic = [nil, '']
magic = [0, nil] if something_something
success = other_method_that_returns_nothing(magic)
if success == true
return true # signal success
end
end

^ That one is from our glorious self-proclaimed leader / "engineering director" / the junior dev thundercunt on a power trip. Good stuff.

Next up are a few of my personal favorites:

Report.run_every 4.hours # Every 6 hours
Daemon.run_at_hour 6 # Daily at 8am

LANG_ENGLISH = :en
LANG_SPANISH = :sp # because fuck standards, right?

And for design decisions...

The code was supposed to support multiple currencies, but just disregards them and sets a hardcoded 'usd' instead -- and the system stores that string on literally hundreds of millions of records, often multiple times too (e.g. for payment, display fees, etc). and! AND! IT'S ALWAYS A FUCKING VARCHAR(255)! So a single payment record uses 768 bytes to store 'usd' 'usd' 'usd'

I'd mention the design decisions that led to the 35 second minimum pay API response time (often 55 sec), but i don't remember the details well enough.

Also:
The senior devs can get pretty much anything through code review. So can the dev accountants. and ... well, pretty much everyone else. Seriously, i have absolutely no idea how all of this shit managed to get published.

But speaking of code reviews: Some security holes are allowed through because (and i quote) "they already exist elsewhere in the codebase." You can't make this up.

Oh, and another!
In a feature that merges two user objects and all their data, there's a method to generate a unique ID. It concatenates 12 random numbers (one at a time, ofc) then checks the database to see if that id already exists. It tries this 20 times, and uses the first unique one... or falls through and uses its last attempt. This ofc leads to collisions, and those collisions are messy and require a db rollback to fix. gg. This was written by the "legendary" dev himself, replete with his signature single-letter variable names. I brought it up and he laughed it off, saying the collisions have been rare enough it doesn't really matter so he won't fix it.

Yep, it's garbage all the way down.

The education system is a fucking joke. How do you get through all the required courses and get to the capstone course where your one goal is to build a simple prototype of a project(like a simple website) for a real world client and not know HTML or CSS when you spent a whole fuckboy semester on a class dedicated to HTML, css, JavaScript and the teacher gave you the PHP. Not only that but you can't even figure out how to use a simple google search to look up the documentation on any of these topics or even the easy to follow tutorials littering the internet on how to use Bootstrap which is what we're fucking using to make it faster to develop the core logic of our app but all you fucking want to do is take shortcuts and create a PowerPoint presentation in google slides and make an easy project look like shit and make me and yourselves look like shit. But don't fucking worry, I'll code the whole thing in a fucking night because you didn't do your part of taking care of just the front end and planned for your incompetence and lack of questions or help. I know you're busy looking for a job for after you graduate but you can't even answer a simple programming question. Let me give you the solution on how to reverse a string, cuz you don't remember c# but it literally takes 30 seconds to google the solution that is everywhere. My project team is why no one takes a degree from this university seriously.

1 + 2 + 3 + 4 + 5 + “6”

[CMS of Doom™]
The gift that keeps on giving...
When you think you've seen it all after 7 months in legacy hell, you get another gift:

Let's say you use PHP, but your IQ is in the zero-ish range, then it is obvious to:
- use define() for constants in all your config.*.php files
- then include said config.*.php files multiple times
- and because define() doesn't overwrite the same constant, because it's - you know - a constant, you instead of including just do a file_get_contents() to read the PHP file as string and then parse the values by Regex.

The dev who wrote this was truly one of the devs ever.

Have you ever pushed out a crap update? What's the most expensive system you've ever brought down?

Today I took down a $0.7M system with an uppercase "S" in a string.

We don't know what one-to-many is! Instead, we convert all associated IDs to a string and join the list into a string separated by commas! Only after this absolute clownery do we save this new nice clean string to the database column! Then, when we want all associated entities, we serialize this list back into an array of IDs and retrieve them! It's clown-genius!

🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡

Oh dear, a scaling problem I solved was replacing some Regex matching with simpler string functions. While I'm a huge fan of Regex, it's unreal how much performance they can suck out of some high-n loops...
I got about 120x out of some critical code thus making a CPU upgrade unnecessary.

Am I the only one ?

15+ years in c# / .net dev and I still google "c# string compare ignore case" each time. Its just fucking faster than to remember exact syntax of the "StringComparison.OrdinalIgnoreCase"

Imagine saving Integers and Floats in a MySQL table as strings containing locale based thousand sepatators...
man... fickt das hart!

Wait, there's more!
Imagine storing a field containing list of object data as a CSV in a single table column instead of using JSON format or a separate DB table.... and later parsing it by splitting the CSV string on ";"...

Add a random string (like "AnyBrowser/1.2.3") to your user agent string, and get warnings about unsupported browsers, reduced functionality, and Google drive completely refusing to start at all.

It's the very same browser, just another user agent string. Ever heard of feature detection? Ever heard of usability, accessibility, progressive enhancement? How can developers be so lost in 2022?

I just tried to reproduce the reason why Vivaldi stopped adding their brand to user agent strings but sails under false flag pretending to be Google chrome. So it doesn't show up in browser statistics either and Google people can keep thinking everyone is using their shitware.

Teaching new devs, hired straight from India.

This is today.

Bug1: We have four lists, each item in these lists has a variable called "Charge". This var is a double and we need to convert it to currency.

Dev creates fifth list called "All lists" and converted it's charge to currency then questioned why it didn't work.

I explained, his solution? Convert each list into currency.

I explained that's wrong and told him what he needed to do. He did List1:Charge into currency, but left his other conversion in place just in case.

I walked him through fixing it which took 10 times as long as necessary, only to find out he randomly converted four booleans into currency for no reason.

Bug2: we take integer, convert to string and concat "Months" on the end.

Doesn't work for him, tells me he doesn't know why.

I told him that he's not outputting the variable that we did it to, he is instead outputting a custom variable he made and didn't do anything to.

Bug 3: followup to #2, he fixed it as I instructed, but then added months as static text to the output so now it reads "Months months".

Bug 4: to make his code cleaner, he presses enter in the text box. Unfortunately he did that IN A STRING so his output is full of random /r/n

How do you guys deal with coworkers like this? He isn't new, this is supposed to be an experienced developer. Im only in my 2nd year

There are so many weird hacks in the quite legacy app I work with I could write a book about all them hacks…

But I must admit, the worst of them all is internal time. Yes, so some blockhead thought it’s a good idea to represent time in a manner completely removed from Datetime objects or timestamps or even string representations. Instead we deal with them as intervals represented by integers - and because this is not fucked up enough by itself, the internal time doesn’t start at midnight, yet the integer representations do. It’s a bloody mess. No wonder most of the bugs we face have to do with dates and time…

Java: String foo =“bar”;
C#: var foo = “bar”;
Go: var foo string = “bar”

I just started learning Go and I’ve been cringing since.

Two C strings walk into a bar.
The bartender asks "What can I get ya?"
The first string says "I'll have a gin and tonic."
The second string thinks for a minute, then says "I'll take a tequila sunriseJF()#$JF(#)$(@J#()$@#())!*FNIN!OBN134ufh1ui34hf9813f8h8384h981h3984h5F!##@"
The first string apologizes, "You'll have to excuse my friend, he's not null-terminated."

Just got a new job at an old school hardware company. The codebase is giving me heart attack. They don't care about dev experience or code navigation at all. Every attempts to modernize the codebase is so half assed. All patches are so bloated that make the codebase even worse.

Frontend is migrated from prototype-oop-jquery cluster fuck to AngularJS, then finally angular. Holy moly, all business logics are baked into UI "classes" using prototype chain. When they migrated to AngularJS, someone simply added a wrapper to that jQuery cluster fuck class and overwrote all the prototype with a 10k +lines file. Since all the methods are hidden in either prototype, JS object, or callback function, it's impossible to trace the data pipeline using IDE when "go to definition" on update() method gives you all the update methods/string in all objects/classes. And they don't care about immutability. References are taken out, renamed, and mutated everywhere. Finding the source of a bug is fucking guessing game.

I don't know what trick they use that makes cLion static analyzer fail.

And there is no unit test or spec doc.

Fuck me dead

In highschool we went through something like a malware/phishing prevention course.

It was pretty cool tbh, we spend the whole hour in a virtual environment where you'd see common malware and phishing attempts, but the really fun you could also "hack" other students.

Hacking them means you could cause some things to happen on their "PC". One of those was showing in a captcha on their screen and they had to type a the string of your choosing, before they could access the rest of the "virtual computer" again.

You can probably guess where this is going.
I was the first who had the idea to mix big i and small L and tested it on our teacher, who was also part of this environment and screenshared to the projector.

Thanks to sitting next projection I could see the pixels and I can confirm: same character, Pixel perfect!

I will forever cherish the memory of my the teacher begging me to undo the "hack" and the chaos that followed amongst my peers 😈

Also one of the excersizes was stupid. Click on a phishing mail and enter your credentials in the form. I asked the teacher WTF kind of credentials they even want me to enter to microsooft.cum and they just said "the credentials obviously" so I think they got their karma🖕

Just had a discussion with a coworker. I noticed he was storing dates as string in mongodb, saying it was better for comparison and because he stored them in UTC. WTH, mongo already stores all dates in UTC and a string date is imposible to compare. I wasted 8 hours finding that last part out.

Rust ahahaah hhaahah ahah

the trait bound `std::result::Result<std::string::String, std::io::Error>: std::convert::AsRef<[u8]>` is not satisfied
the trait `std::convert::AsRef<[u8]>` is not implemented for `std::result::Result<std::string::String, std::io::Error>`

So at work, there is this class/model thing that's for storing translated strings. It also supports n-level nested macros, cascading lookup (e->d->c->b->a->blank), and I've added transforms too. The code is a bloody mess and very inefficient (legendary dev's code), but it's useful.

You call methods with a symbol representing one of the strings, and it does... whatever you ask, like return text, booleans, expand macros and submacros, pass in data to interpolate, etc.

But I just learned something today.
Its `.html` method... doesn't support html. In fact, calling it strips out all html, takes whatever is left, and attempts to convert that back into html. Because that makes so much sense. So, if you have an html string? Don't call html on it.

Also, macros use the same <angle brackets> as html tags, and macro expansion eats unknown macros, so... you can't mix html and macros, meaning you cannot inject values into your markup. That's a freaking joy to work around. (You end up writing a parser every time.)

So no, if you have an html string, you need to get the raw data out and handle it yourself. Don't reach for that shiny .html method; it'll just ruin your day.

It's the little things that make my day so terribly long.

Wasted a day as Shitlock Holmes with the build chain.

It would not reproduce the firmware hexfile that had been checked in. Reverse engineering that along with the mapfile to find out the cause, it was a const string that was guarded by an ifdef from another file that was auto-generated as prebuild step via a script that fetched some version control info.

Or, it would have been if the installation instructions had been correct and someone had described that no spaces in the absolute path name of the project are allowed. Otherwise, that shit just failed silently.

I then had to reverse engineer the intended workflow from the commit history in the version control to figure out that the last dev obviously hadn't quite understood the project specific workflow and how the version control interacts with these build scripts.

At least, I finally did get a matching hexfile.

Why does the content of my comment have to disappear when I accidentally click next to the post button?!

So many times I wanted to comment something, lost the content and said 'fuck this' because of it.

Just keep the string for as long as I'm on the same rant and not reply to a different person..

Why are you trying to multithreaded c++ file i/o? If you can't write c++ code that's faster than your hard drive, please just don't write c++.

Literally no complex calculations, just some insane string formatting.

Sharing a first look at a prototype Web Components library I am working on for "fun"

TL;DR left side is pivot (grouped) table, right side is declarative code for it (Everything except the custom formatting is done declaratively, but has the option to be imperative as well).

====

TL;DR (Too long, did read):

I'm challenging myself to be creative with the cool new things that browsers offer us. Lani so far has a focus on extreme extensibility, abstraction from dependencies, and optional declarative style.

It's also going to be a micro CSS framework, but that's taking the back-seat.

I wanted to highlight my design here with this table, and the code that is written to produce this result.

First, you can see that the <lani-table> element is reading template, data, and layout information from its child elements. Besides the custom highlighting code (Yellow background in the "Tags" column, and green gradient in the "Score" column), everything can be done without opening even a single script tag.

The <lani-data-source> element is rather special. It's an abstraction of any data source, and you, as a developer can add custom data sources and hook up the handlers to your whim (the element itself uses the "type" attribute to choose a handler. In this case, the handler is "download" which simply sends a fetch request to the server once and downloads the result to memory).

Templates are stored in an html file, not string literals (Which I think really fucks the code) and loaded async, then cached into an object (so that the network tab doesn't get crowded, even if we can count on the HTTP cache). This also has the benefit of allowing me to parse the HTML templates once and then caching the parsed result in memory, so templates are never re-parsed from string no matter how many custom elements are created.

Everything is "compiled" into a single, minified .js file that you include on your page.

I know it's nothing extraordinary, but for something that doesn't need to be compiled, transpiled, packaged, shipped, and kissed goodnight, I think it's a really nice design and I hope to continue work on it and improve it over time

I've been working with Golang for a while now and I've come to love the generics they introduced. Making stuff type-safe is a bit of a hassle, but it pays off greatly.

One thing I had yet to consider though, is that functions are also a type, so that those could be made generic too.

func DoThing[F func(string) | func(int)](callback F) {...}

Now you can deliver both function types and I can differentiate them using a type switch.

Weird that sometimes my brain doesn't make that connection immediately...

I know streams are useful to enable faster per-chunk reading of large files (eg audio/ video), and in Node they can be piped, which also balances memory usage (when done correctly). But suppose I have a large JSON file of 500MB (say from a scraper) that I want to run some string content replacements on. Are streams fit for this kind of purpose? How do you go about altering the JSON file 'chunks' separately when the Buffer.toString of a chunk would probably be invalid partial JSON? I guess I could rephrase as: what is the best way to read large, structured text files (json, html etc), manipulate their contents and write them back (without reading them in memory at once)?

Fuck Apache TIKA.
Its supposed to be a "universal file reader" or some shit. Im trying to use it as a PDF/image parser that does OCR when needed and yelds a full-file string. It does so, but the text ends up being IN THE WRONG FUCKING ORDER.
WTF would I want to parse the text out of a PDF in any order that is not the one the text is supposed to be read?!?!
"It is more efficient to work in random ordering", says the docs. No shit, really? Wouldn't it be even more efficient to just spit out random strings? Just as useful and 100% CPU-bound.
"You can add a property to forcefully put the text in the right order". THEN WHY THE FUCK IT IS NOT THE DEFAULT SETTING?
Srsly, what's the use case to a parser that yields scrambled text?!?

Generic arguments can't be cast. List<Dog> can't be cast to List<Animal>, because any methods that take Dog as an argument would suddenly have to work with an Animal (same works the other way round with return values).

But there are many situations where this would be okay. For instance, a Date can be cast to a String, so if we know that no method directly or indirectly accessible from a ListView<T> (including accessible property and field setters) will ever take an argument of type T, then ListView<Date> can be cast to a ListView<String>. Conversely, if we know that methods of StreamWriter will only ever take arguments of the generic type and interact in ways that don't change the object, then we can safely cast a StreamWriter<String> to a StreamWriter<Date>.

There could be a pair of generic constraints signifying that the type only crosses the interface boundary in one direction. I think this would be an interesting feature, but I don't know any strict type system that allows it. What do you think?

Can we take a moment to recognize how absolutely retarded JS' event system is?
Events aren't objects. No, they're managed by an object, and identified by a string.
To subscribe to an event, you call object.addEventListener(name, callback). Because for some reason we can't just have an event object. Events MUST have an owner.
But to unsubscribe you don't call the function addEventListener returned, you don't use the token it returned either. No, you pass the same function to removeEventListener.
Because we don't use serializable tokens like in PP, and we don't return functions like in FP, no, we use functions as tokens, realising idiomatic DFP.

Kinda often, the ecosystem around C/C++ kinda sucks

Compilers will give you hieroglyphs instead of readable errors.
Including a separate library, or a code generator, into your project is generally hell on earth to set up.
The language server often needs several seconds to come up with suggestions, some of which are complete nonsense.
The language itself lacks many basic features. C++20 will give us so many fancy things but we still can't convert an enum to a string.

I've programmed in C# and lately in Rust, and damn the developer experience there is just so much nicer overall.

Like 4 years ago I worked in a company as IT that used a windows desktop app with SQL Server 2008 (yep that old) to manage their sales, this app was written in WPF, the app was good because it was customizable with reports

One day the boss wanted to keep extra some data in the customer invoice, so they contacted the app developers to add this data to the invoice, so they they did it, but it in their own way, because the didn't modify the app itself(even if it was an useful idea for the app and companies that use it) they just used other unused fields in the invoice to keep this data and one of the field that the boss was interested was currency rate, later I verified in the DB this rate was saved as string in the database

The boss was not interested in reports because he just wanted to test it first and let time to know what the boss will need in the reports, so at the of the year they will contact again the devs to talk about the reports

So is the end of that year and the boss contacted the devs to talk about the reports of the invoices using the currency rate, this rate was just printed in the invoice nothing more, that's what the boss wanted that's what's the devs did, but when asked to do the reports they said they could'nt because the data was saved as string in the DB o_O

Well, that was one the most stupid excuses I ever heard...

So I started to digging on it and I found why... and the reason is that they were just lazy, at the end I did it but it took some work and the main the problem was that the rate was saved like this 1,01 here we use comma for decimal separator but in SQL you must use the dot (.) as decimal separator like this 1.01, also there was a problem with exact numbers, for example if the rate was exactly 1, that data must be saved just 1 in the field, but it was saved as 1,00 so not just replace all the commas with dots, it's also delete all ,00 and with all that I did the reports for my boss and everyone was happy

Some programmers just want to do easy things...

Wow, thanks apple

For fuck's sake Microsoft, why on Earth do you announce a half-done feature? Was this an idea from marketing? Upper management? I am fairly certain that nobody who actually writes code for a living would have ever approved releasing a rushed feature to a TYPE SYSTEM.

Anyone tried converting speech waveforms to some type of image and then using those as training data for a stable diffusion model?

Hypothetically it should generate "ultrarealistic" waveforms for phonemes, for any given style of voice. The training labels are naturally the words or phonemes themselves, in text format (well, embedding vectors fwiw)

After that it's a matter of testing text-to-image, which should generate the relevant phonemes as images of waveforms (or your given visual representation, however you choose to pack it)

I would have tried this myself but I only have 3gb vram.

Even rudimentary voice generation that produces recognizable words from text input, would be interesting to see implemented and maybe a first for SD.

In other news:
Implementing SQL for an identity explorer. Basically the system generates sets of values for given known identities, and stores the formulas as strings, along with the values.
For any given value test set we can then cross reference to look up equivalent identities. And then we can test if these same identities hold for other test sets of actual variable values. If not, the identity string cam be removed, or gophered elsewhere in the database for further exploration and experimentation.

I'm hoping by doing this, I can somewhat automate the process of finding identities, instead of relying on logs and using the OS built-in text search for test value (which I can then look up in the files that show up, and cross reference the logged equations that produced those values), which I use to find new identities.

I was even considering processing the logs of equations and identities as some form of training data perhaps for a ML system that generates plausible new identities but that's a little outside my reach I think.

Finally, now that I know the new modular function converts semiprimes into numbers with larger factor trees, I'm thinking of writing a visual browser that maps the connections from factor tree to factor tree, making them expandable and collapsible, andallowong adjusting the formula and regenerating trees on the fly.

can somebody tell me why a string has (n*(n+1)/2) substrings?

I don't trust this model will perform for long

[Rust] What are alternatives to argument drilling for something like a string interner which is technically a memory leak so it really shouldn't be global but at the same time all but a couple top level functions depend on its existence? I'm aware of context objects and that's all ChatGPT could give me as well, but I'm wondering if there's more to this problem than that.

Why aren't template literal keys allowed, and _why_ isn't there a proper error message for them?

@highlight
searchThrottle.Throttle(TimeSpan.FromMilliseconds(200))
.Select(e => ((string)e.Value)?.Trim())
.DistinctUntilChanged()
.Subscribe((x) =>
{
quisckSearch = x;
InvokeAsync(async () => await LoadFirstPage());
});

So is the difference between inheritance and composition is that of a fridge and iceman?

class Man {
fun greet(){return "hi"}
}

class IceMan extends Man{
override fun greet(){return "hi i am iceman"}
fun getIce(){return "ice"*Random.nextInt()}
}

class Fridge{
private Man manAi;
private String s = "ice";
fun greet(){return manAi.greet()}
fun getIce(){return s*Random.nextInt()}
}

}

=========
Basically , in first case, a class is getting features by inheriting from parent while in another case, a class is getting features by internally having objects of other classes that could provide those features?

I just love when an API returns a set of results, some have property X as a string and some as a JSON array. Wtf? Good people had put great API wrappers and it works if X is string as per service specification, but breaks otherwise, unsurprisingly.

I had to do a pull request to the wrapper repository to account for this inconsistency 😶

Terraform + helm-chart ... I really ned a break. Who the fuck invented this shit.
The HCL format sucks
The documentation sucks
The dev tools suck
The debug output sucks

But I'm ok with that, I can manage.
But today really it shot the bird ... I can't have a fucking comma in a string? Because idk why the fuck helm-release tries to parse that fucking string and wants to make an array or whatever out of it? Why, you fucking abomination?
Something in the docs? Nah, who reads them anyway.
Because you know it's totally not strange that a string is analyse and oh wait there's a comma in it, the dev surely wants me to make an array out of it, because you know ...
So now I have to escape my fucking comma to prevent it to parse my fucking string. I just want to have a fucking string you hideous monstrosity ....

I implore ANYONE... please...

Have you EVER written a SINGLE Jest test that didn't have some sort of bullshit spewing stuff like this:

"ReferenceError: You are trying to `import` a file after the Jest environment has been torn down."

"Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports."

and yet running on a device, features work flawlessly and quite well, no errors or even warnings in sight logged

This is the most fragile pile of garbage I have ever seen.

I hate this.

inb4 your stupid ass todo boilerplate garbage you wrote tests for in freshman year. i'm talking about a REAL app with HUNDREDS of components.

where the grownup testing tools at? it's a question I've still not answered after a year of fucking around with this framework

Holy f-ing hell!
Why do the small things have such fucked up corner cases?
This is very likely a giant bug with Qt, but how does this even happen?
I am using Qt with QML and sending data to a database on the backend. I call functions in QML from a Date JS object (property actually, but it calls functions) to set the date as a QDate. This is stored in the database as yyyy/MM/dd. This is fine. When I read the date out I convert it back from string to QDate and send this object to QML. Which then converts this to a Date object in JS in QML.

But at the point where it converts from a QDate to a Date object it loses an entire day. Seriously? You didn't gain a day going from Date -> QDate, but you lose a day going from QDate -> Date?

How long has QML and Qt been around? At least 5 to 10 years. How has this bug lasted this long? I don't want to do a bug report. I will, but I don't want to .

Why is it that search engines behave differently when you're using a mobile device versus a computer? I get far better results using a computer. On the mobile device the meta characters don't seem to work very well. For instance, I will use a minus sign to exclude a word or phrase and a whole lot of the results come back with that word or phrase in them. All you're doing is sending a string up to the cloud where the lookup occurs. What's the difference between sending a string from a mobile device or a computer?

Mongodb CEO and the developer who build this shit for brains interface should be tarred and feathered. Almost 90minutes in and I cannot connect to anything other than error codes. What in the actual fuck is your job other than to make it difficult for a "free tier" user to connect?
"connect ECONNREFUSED 127.0.0.1:27017"

Oh ok another 20 minutes of work and you give me a bland beige error code like "```TLS/SSL is disabled. If possible, enable TLS/SSL to avoid security vulnerabilities.```"... um ok how do I enable it for your site, your database or on my computer... oh wait you don't say shit do you?

So now I'm fully 81 minutes into this shit show and all I get for error codes are these really descriptive gems 'getaddrinfo ENOTFOUND cluster0.hudbd.mongodb 'dot' net` comes up if I choose `mongo` with "connection string scheme" above it or `bad auth : Authentication failed'

In python, is there a way to make this work?

----------
# list of people
people = ["Nick", "Sue", "Bob"]

# class instance
Bob.pockets = ["gum", "paperclip", "coins"]

# convert string to prefix of a class instance
Print(people[2].pockets())

----------

This is the simplest way to show what I'm needing to figure out.

I need to convert a string into the prefix of a class instance.

I'm having trouble figuring it out.

GitLab, you really should fix your CI.

I mean, I know .gitlab-ci.yml has to be written carefully, having in mind that GL shell is a castrated bourne shell, but come on... Failing a pipeline because I used a semicolon in an `echo` parameter string?

echo ""items: 0" ## this will fail
echo "items 0" ## this will pass

This is a bit too much.

Removed the semicolon and the pipeline worked just fine.

line breaks after 100 or so characters suck. function chaining will look bad in one line, but it doesn't mean we need to limit all our lines to a hard length.
ex:

config.logger.e(TAG, "func() called with: p1 = $p1, p2 = $p2, p3 = $p3, p4 = $p4, p5 = $p5")
this is a standard log that i add at the start of my functions . its easy to autogenerate in intellij , even if my class and variable names are much long (like mVideoAnalyticsManager) . when these variables and their string names add up, they will easily go out of the screen and i won't mind scrolling a few seonds to the left to ensure everything is correct (which 99.9% is)

but a fucking ctrl+alt+l and all strings are broken with a fucking +

AAGh its just irritating ://////

What is the point of kubernetes "secrets" if it encodes the sensitive information as a base64 string if anyone can decode and read raw data using any base64 decoder tool?

having a DSA interview in 2 days, any suggestions on how/what to prepare?

its been years since i tried solving coding problems with anything apart from strings or arrays( and that too the one we use in dev, like writing a function to convert string to uppercase, that's all i remember)

There are a million algorithms: knapsac, djikstra, DFS BFS, bellman ford, TRIE, BST, quick sort, merge sort, insertion , binary search... these are some buzz words i could remember from my early college days, 6 years ago. I was able to understand and learn them at that time, but now i know shit about them :/

How to go with all of these in 48 hours?

Utility libraries, because I actually get to see my life improve because I have them. Creating new projects becomes easier because I put parts I reuse somewhere else.

There was an old config file generator/manager I kept using for a while, some string conversion libraries between formats, some REST/WebRTC API wrappers, I have a web audio API I create tunes with in various projects. CI/CD scripts for laziness so I never have to know how to set anything up again. Lately the thing I'm most happy about is I turned some free text saving service into a makeshift database and it's been working well for about half a dozen projects now. Wouldn't handle large amount of users but can't beat free and easy.

I also find merit in prototypes/old projects, because I can reference random things I did in them in newer unrelated projects. Things too small to warrant their own utility library, argh!

Since Google is failing me...

Given a user input (string query) and a list of larger strings (like email bodies or something), what's the best way to search and rank the list of strings against the user input.

So far I have implemented levenshtein distance but it doesn't really seem to do extremely well. (Short strings rank very well against each other, whereas long strings **containing** exact matches will go lower in the list)

Should I be splitting the input and the list by word and then averaging the distances?

The only thing I have tried is removing complete non-matches from the list by not including them if the distance is equal to the length of the largest string

Why the fuck does B&R's find in string function return 0 when the search string was not found? The return type is not even unsigned?!

today the backend dev told me that he was trying to setup typescript for the company for so long and the company resisted him but he was super proud of his achievement of getting typescript into the project and i told him. sorry I agree with the company, you're stupid
i didn't tell him he was stupid ofcourse but i told him why i thought it was an unnecessary dep
i asked him are you doing a lot of number crunching? he said no
and i told him, most of the data you're going to recieve is in a string format or in json strings
very rarely are you going to get number data
and you can easily coerce the data into whatever you want

I am trying to extract data from the PubSub subscription and finally, once the data is extracted I want to do some transformation. Currently, it's in bytes format. I have tried multiple ways to extract the data in JSON format using custom schema it fails with an error

TypeError: __main__.MySchema() argument after ** must be a mapping, not str [while running 'Map to MySchema']

**readPubSub.py**

Please let me know if I m doing something wrong while parsing the data to JSON. Also, I am looking for examples to do data masking and run some SQL within Apache Beam

What would be the easiest way to make line 16 work.

I don't know if there is a simple way to tell this "if" argument to check all af the "Remote Host" classes for a matching string at that index.

I'm trying to design with modularity in mind.

Had a jira ticket for a cpanel user where the end user creates any database through mysql database ends up with already exists. No matter what string we take though.

Anyone had this error before? Will update log sooner

In type systems without variadic generics, tuples should be defined as a type-level conslist:

Tuple<int, Tuple<string, Tuple<bool, TupleEnd>>>

Consider the possibilities, even just in a regular type system, then consider how much more is possible with dependent types!
