So, you start with a PHP website.

Nah, no hating on PHP here, this is not about language design or performance or strict type systems...

This is about architecture.

No backend web framework, just "plain PHP".

Well, I can deal with that. As long as there is some consistency, I wouldn't even mind maintaining a PHP4 site with Y2K-era HTML4 and zero Javascript.

That sounds like fucking paradise to me right now. 😍

But no, of course it was updated to PHP7, using Laravel, and a main.js file was created. GREAT.... right? Yes. Sure. Totally cool. Gotta stay with the times. But there's still remnants of that ancient framework-less website underneath. So we enter an era of Laravel + Blade templates, with a little sprinkle of raw imported PHP files here and there.

Fine. Ancient PHP + Laravel + Blade + main.js + bootstrap.css. Whatever. I can still handle this. 🤨

But then the Frontend hipsters swoosh back their shawls, sip from their caramel lattes, and start whining: "We want React! We want SPA! No more BootstrapCSS, we're going to launch our own suite of SASS styles! IT'S BETTER".

OK, so we create REST endpoints, and the little monkeys who spend their time animating spinners to cover up all the XHR fuckups are satisfied. But they only care about the top most visited pages, so we ALSO need to keep our Blade templated HTML. We now have about 200 SPA/REST routes, and about 350 classic PHP/Blade pages.

So we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + React + SPA 😑

Now the Backend grizzlies wake from their hibernation, growling: We have nearly 25 million lines of PHP! Monoliths are evil! Did you know Netflix uses microservices? If we break everything into tiny chunks of code, all our problems will be solved! Let's use DDD! Let's use messaging pipelines! Let's use caching! Let's use big data! Let's use search indexes!... Good right? Sure. Whatever.

OK, so we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + React + SPA + Redis + RabbitMQ + Cassandra + Elastic 😫

Our monolith starts pooping out little microservices. Some polished pieces turn into pretty little gems... but the obese monolith keeps swelling as well, while simultaneously pooping out more and more little ugly turds at an ever faster rate.

Management rushes in: "Forget about frontend and microservices! We need a desktop app! We need mobile apps! I read in a magazine that the era of the web is over!"

OK, so we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + GraphQL + React + SPA + Redis + RabbitMQ + Google pub/sub + Neo4J + Cassandra + Elastic + UWP + Android + iOS 😠

"Do you have a monolith or microservices" -- "Yes"

"Which database do you use" -- "Yes"

"Which API standard do you follow" -- "Yes"

"Do you use a CI/building service?" -- "Yes, 3"

"Which Laravel version do you use?" -- "Nine" -- "What, Laravel 9, that isn't even out yet?" -- "No, nine different versions, depends on the services"

"Besides PHP, do you use any Python, Ruby, NodeJS, C#, Golang, or Java?" -- "Not OR, AND. So that's a yes. And bash. Oh and Perl. Oh... and a bit of LUA I think?"

2% of pages are still served by raw, framework-less PHP.

Popularity of programming languages according to the DRRDSI (DevRant Rubber Duck Selling Index):

1. JS
2. Java
3. Python
4. C#
5. PHP
6. C++
7. Ruby
8. SQL
9. Swift

If programming languages where weapons...

1. C is an M1 Garand standard issue rifle, old but reliable.

2. C++ is a set of nunchuks, powerful and impressive when wielded but takes many years of pain to master and often you probably wish you were using something else.

3. Perl is a molotov cocktail, it was probably useful once, but few people use it

4. Java is a belt fed 240G automatic weapon where sometimes the belt has rounds, sometimes it doesn’t, and when it doesn’t during firing you get an NullPointerException, the gun explodes and you die.

5. Scala is a variant of the 240G Java, except the training manual is written in an incomprehensible dialect which many suspect is just gibberish.

6. JavaScript is a sword without a hilt.

7. Go is the custom made “if err != nil” starter pistol and after each shot you must check to make sure it actually shot. Also it shoots tabs instead of blanks.

8. Rust is a 3d printed gun. It may work some day.

9. bash is a cursed hammer, when wielded everything looks like a nail, especially your thumb.

10. Python is the “v2/v3” double barrel shotgun, only one barrel will shoot at a time, and you never end up shooting the recommended one. Also I probably should have used a line tool to draw that.

11. Ruby is a ruby encrusted sword, it is usually only used because of how shiny it is.

12. PHP is a hose, you usually plug one end into a car exhaust, and the other you stick in through a window and then you sit in the car and turn the engine on.

13. Mathematica is a low earth orbit projectile cannon, it could probably do amazing things if only anyone could actually afford one.

14. C# is a powerful laser rifle strapped to a donkey, when taken off the donkey the laser doesn’t seem to work as well.

15. Prolog is an AI weapon, you tell it what to do, which it does but then it also builds some terminators to go back in time and kill your mom

...9 years later...

I've had many, but this is one of my favorite "OK, I'm getting fired for this" moments.

A new team in charge of source control and development standards came up with a 20 page work-instruction document for the new TFS source control structure.
The source control kingpin came from semi-large military contract company where taking a piss was probably outlined somewhere.

Maybe twice, I merged down from a release branch when I should have merged down from a dev branch, which "messed up" the flow of code that one team was working on.
Each time I was 'coached' and reminded on page 13, paragraph 5, sub-section C ... "When merging down from release, you must verify no other teams are working
on branches...blah blah blah..and if they have pending changes, use a shelfset and document the changes using Document A234-B..."

A fellow dev overheard the kingpin and the department manager in the breakroom saying if I messed up TFS one more time, I was gone.

Wasn't two days later I needed to merge up some new files to Main, and 'something' happened in TFS and a couple of files didn't get merged up. No errors, nothing.
Another team was waiting on me, so I simply added the files directly into Main. Unknown to me, the kingpin had a specific alert in TFS to notify him when someone added
files directly into Main, and I get a visit.

KP: "Did you add a couple of files directly into Main?"
Me:"Yes, I don't what happened, but the files never made it from my branch, to dev, to the review shelfset, and then to Main. I never got an error, but since
they were new files and adding a new feature, they never broke a build. Adding the files directly allowed the Web team to finish their project and deploy the
site this morning."
KP: "That is in direct violation of the standard. Didn't you read the documentation?"
Me: "Uh...well...um..yes, but that is an oddly specific case. I didn't think I hurt any.."
KP: "Ha ha...hurt? That's why we have standards. The document clearly states on page 18, paragraph 9, no files may ever be created in Main."
Me: "Really? I don't remember reading that."
<I navigate to the document, page 18, paragraph 9>
Me: "Um...no, it doesn't say that. The document only talks about merging process from a lower branch to Main."
KP: "Exactly. It is forbidden to create files directly in Main."
Me: "No, doesn't say that anywhere."
KP: "That is the spirit of the document. You violated the spirit of what we're trying to accomplish here."
Me: "You gotta be fracking kidding me."

KP grumbles something, goes back to his desk. Maybe a minute later he leaves the IS office, and the department manager leaves his office.

It was after 5:00PM, they never came back, so I headed home worried if I had a job in the morning.

I decided to come in a little early to snoop around, I knew where HR kept their terminated employee documents, and my badge wouldn't let me in the building.

Oh crap.

It was a shift change, so was able to walk in with the warehouse workers in another part of the building (many knew me, so nothing seemed that odd), and to my desk.

I tried to log into my computer...account locked. Oh crap..this was it. I'm done. I fill my computer backpack with as much personal items as I could, and started down the hallway when I meet one of our FS accountants.

L: "Hey, did your card let you in the building this morning? Mine didn't work. I had to walk around to the warehouse entrance and my computer account is locked. None of us can get into the system."

*whew!* is an understatement. Found out later the user account server crashed, which locked out everybody.

Never found out what kingpin and the dev manager left to talk about, but I at least still had a job.

One of the morons said today that we should use C because you don't need to "apply logic" in Python. Everything is automated in python. Fucking morons............

It doesn't ends here. One of the "9 pointers gang" student raised an objection. I was happy untill he said that there is no boolean datatype in C. I literally shouted "Shut up, morons. There is a whole fucking library dedicated to it." in a class of 60 students.

Don't know how I survived 3 years here. And more importantly, don't know how will I survive my next year.

P.S.: the 9 pointer guy who raised the objection, once asked me whether chrome is developed and maintained by Google?

I had to open the desktop app to write this because I could never write a rant this long on the app.

This will be a well-informed rebuttal to the "arrays start at 1 in Lua" complaint. If you have ever said or thought that, I guarantee you will learn a lot from this rant and probably enjoy it quite a bit as well.

Just a tiny bit of background information on me: I have a very intimate understanding of Lua and its c API. I have used this language for years and love it dearly.

[START RANT]

"arrays start at 1 in Lua" is factually incorrect because Lua does not have arrays. From their documentation, section 11.1 ("Arrays"), "We implement arrays in Lua simply by indexing tables with integers."

From chapter 2 of the Lua docs, we know there are only 8 types of data in Lua: nil, boolean, number, string, userdata, function, thread, and table

The only unfamiliar thing here might be userdata. "A userdatum offers a raw memory area with no predefined operations in Lua" (section 26.1). Essentially, it's for the API to interact with Lua scripts. The point is, this isn't a fancy term for array.

The misinformation comes from the table type. Let's first explore, at a low level, what an array is. An array, in programming, is a collection of data items all in a line in memory (The OS may not actually put them in a line, but they act as if they are). In most syntaxes, you access an array element similar to:

array[index]

Let's look at c, so we have some solid reference. "array" would be the name of the array, but what it really does is keep track of the starting location in memory of the array. Memory in computers acts like a number. In a very basic sense, the first sector of your RAM is memory location (referred to as an address) 0. "array" would be, for example, address 543745. This is where your data starts. Arrays can only be made up of one type, this is so that each element in that array is EXACTLY the same size. So, this is how indexing an array works. If you know where your array starts, and you know how large each element is, you can find the 6th element by starting at the start of they array and adding 6 times the size of the data in that array.

Tables are incredibly different. The elements of a table are NOT in a line in memory; they're all over the place depending on when you created them (and a lot of other things). Therefore, an array-style index is useless, because you cannot apply the above formula. In the case of a table, you need to perform a lookup: search through all of the elements in the table to find the right one. In Lua, you can do:

a = {1, 5, 9};
a["hello_world"] = "whatever";

a is a table with the length of 4 (the 4th element is "hello_world" with value "whatever"), but a[4] is nil because even though there are 4 items in the table, it looks for something "named" 4, not the 4th element of the table.

This is the difference between indexing and lookups. But you may say,

"Algo! If I do this:

a = {"first", "second", "third"};
print(a[1]);

...then "first" appears in my console!"

Yes, that's correct, in terms of computer science. Lua, because it is a nice language, makes keys in tables optional by automatically giving them an integer value key. This starts at 1. Why? Lets look at that formula for arrays again:

Given array "arr", size of data type "sz", and index "i", find the desired element ("el"):

el = arr + (sz * i)

This NEEDS to start at 0 and not 1 because otherwise, "sz" would always be added to the start address of the array and the first element would ALWAYS be skipped. But in tables, this is not the case, because tables do not have a defined data type size, and this formula is never used. This is why actual arrays are incredibly performant no matter the size, and the larger a table gets, the slower it is.

That felt good to get off my chest. Yes, Lua could start the auto-key at 0, but that might confuse people into thinking tables are arrays... well, I guess there's no avoiding that either way.

🍿🍿 pull up a chair and get comfy. This was a few years ago and anger has filled some details, so bear with me...

One day, during one of rare afternoons off of work, I was in the library to work on a group project for school. This was maybe a month before it was due, so we were tracking for decent progress and one less stressor over finals. It was about 80° F out, with the perfect breeze for the beach, but school comes first.

I'm team lead (which is terrifying, but less important) and my bro C shows up early to be ready to go on time because he's professional. I'M SO BAD I FORGOT DOUCHEBAGS NAME, so he's A (for asshole), shows up AN HOUR AND 15 MINUTES LATE. But it's not the end of the world, C and I worked around our database schema (which A sent us and we approved), so we could iron out kinks as we went.

A gets there... Fucking finally.

Fucker didn't have the database built (had 2 months to do it, we all agreed on schema a month prior. We're trying to be the adults our ages claim is to be).

*breathe in, count to 10* not a problem, A, just go ahead and start it now so we can at least check what we have.

Ok, my queen, I'll have it done in 10 minutes...

🤔🤔

We needed an id (sku... Which, in 99.9999% of companies is numeric), a short name (xBox one, Macbook, don't smart tv), a description and a price (with 2 decimals). All approved by all 3 of us.

His sku ranges from 3 to 9 ALPHA NUMERIC CHARACTERS, the names were even more generic than expected (item1, item 2, Item_3), no description, and he somehow thought US currency had 5 decimal places!!! (it's more accurate...)

There was an epic, royal, and expensive fight scene in the library (may have been during the Lenten season I decided to give up caffeine AND fast for 40 days to prove a point to an ass wipe of a history teacher, don't recall). I made him cry, he failed the class because C and I wound up fixing everything he touched (graded by commits, because it was also an intro to git, but also, a classmate saw it all), and I had to buy multiple people coffee for yelling in the library.

A tried making out buttons work (I was fed up and done thinking for the day, so moved to documentation), but he fucked those up. I then made those worse by having nested buttons, but I deleted all his shit and started over and fixed it.

I then cried, but C and I survived and have each others backs still.

I'm in grade 9.
I started a programming club in my school.
I told them that I'd teach basic HTML,JS,CSS,C++,C,Java.
Nobody signed up.
Because it happens on Thursdays.
FML.
However, people told other people that I have wicked programming skills and so one of the school staff asked me to help them maintain their school website, which is currently just Google Sites (*vomit).
:(

Still trying to get good.

The requirements are forever shifting, and so do the applied paradigms.

I think the first layer is learning about each paradigm.

You learn 5-10 languages/technologies, get a feeling for procedural/functional/OOP programming. You mess around with some electronics engineering, write a bit of assembly. You write an ugly GTK program, an Android todo app, check how OpenGL works. You learn about relational models, about graph databases, time series storage and key value caches. You learn about networking and protocols. You void the warranty of all the devices in your house at some point. You develop preferences for languages and systems. For certain periods of time, you even become an insufferable fanboy who claims that all databases should be replaced by MongoDB, or all applications should be written in C# -- no exceptions in your mind are possible, because you found the Perfect Thing. Temporarily.

Eventually, you get to the second layer: Instead of being a champion for a single cause, you start to see patterns of applicability.

You might have grown to prefer serverless microservice architectures driven by pub/sub event busses, but realize that some MVC framework is probably more suitable for a 5-employee company. You realize that development is not just about picking the best language and best architecture -- It's about pros and cons for every situation. You start to value consistency over hard rules. You realize that even respected books about computer science can sometimes contain lies -- or represent solutions which are only applicable to "spherical cows in a vacuum".

Then you get to the third layer: Which is about orchestrating migrations between paradigms without creating a bigger mess.

Your company started with a tiny MVC webshop written in PHP. There are now 300 employees and a few million lines of code, the framework more often gets in the way than it helps, the database is terribly strained. Big rewrite? Gradual refactor? Introduce new languages within the company or stick with what people know? Educate people about paradigms which might be more suitable, but which will feel unfamiliar? What leads to a better product, someone who is experienced with PHP, or someone just learning to use Typescript?

All that theoretical knowledge about superior paradigms won't help you now -- No clean slates! You have to build a skyscraper city to replace a swamp village while keeping the economy running, together with builders who have no clue what concrete even looks like. You might think "I'll throw my superior engineering against this, no harm done if it doesn't stick", but 9 out of 10 times that will just end in a mix of concrete rubble, corpses and mud.

I think I'm somewhere between 2 and 3.

I think I have most of the important knowledge about a wide array of languages, technologies and architectures.

I think I know how to come to a conclusion about what to use in which scenario -- most of the time.

But dealing with a giant legacy mess, transforming things into something better, without creating an ugly amalgamation of old and new systems blended together into an even bigger abomination? Nah, I don't think I'm fully there yet.

Once upon a time as a developer for Palm handhelds I wrote an application in C which had to print via a Bluetooth printer.
When connected by wire everything was perfect, switching to BT it kept crashing for weeks without me finding the source of the problem.
Then came the day of my companies summer party. I've been the last guy to sit in front of the PC, investigating my problem, when at about 9 PM my boss came and told me, I should grab something to eat. So I went down, drank three beer and got back to work.
At about 9:45 PM the damn wrong * was replaced by the correct & and everything was fine.

PointerIssuesSolvedByBeer++;

Once, at school, last year, we had to present a C# project that, upon clicking a button, took words from a .txt file and showed them in an alphabetical listBox...

Since the file they gave us was so long that we had to wait a minute or so to get the listBox full, I implemented a progressBar which popped up on the button, and upon clicking it, the progressBar advanced for every word it loaded, until, upon finishing, it would have disappear leaving again the button, and the listBox would have been loaded.

Apparently, this choice alone – even if it had next to nothing to do with the exercise – was enough to give me a solid 9 out of 10, because our professors never explained us about progressBars and I used that completely on my own... I tend to do things like this in class, where I explore what my tools could give me.

So long story short, I ended up having the best vote in class for that, and I was so happy and motivated :D

Moral of the story: if you can, always try to learn something new about your tools and your programming language, on your own, because apparently it gives you advantage towards others, at least in school. Or even if you're not in school, it could still be something cool to learn that might be helpful in the future, for your projects or your job's projects.
The more you know, the better!

WASM was a mistake. I just wanted to learn C++ and have fast code on the web. Everyone praised it. No one mentioned that it would double or quadruple my development time. That it would cause me to curse repeatedly at the screen until I wanted to harm myself.

The problem was never C++, which was a respectable if long-winded language. No no no. The problem was the lack of support for 'objects' or 'arrays' as parameters or return types. Anything of any complexity lives on one giant Float32Array which must surely bring a look of disgust from every programmer on this muddy rock. That is, one single array variable that you re-use for EVERYTHING.

Have a color? Throw it on the array. 10 floats in an object? Push it on the array - and split off the two bools via dependency injection (why do I have 3-4 line function parameter lists?!). Have an image with 1,000,000 floats? Drop it in the array. Want to return an array? Provide a malloc ptr into the code and write to it, then read from that location in JS after running the function, modifying the array as a side effect.

My- hahaha, my web worker has two images it's working with, calculations for all the planets, sun and moon in the solar system, and bunch of other calculations I wanted offloaded from the main thread... they all live in ONE GIANT ARRAY. LMFAO.If I want to find an element? I have to know exactly where to look or else, good luck finding it among the millions of numbers on that thing.

And of course, if you work with these, you put them in loops. Then you can have the joys of off-by-one errors that not only result in bad results in the returned array, but inexplicable errors in which code you haven't even touched suddenly has bad values. I've had entire functions suddenly explode with random errors because I accidentally overwrote the wrong section of that float array. Not like, the variable the function was using was wrong. No. WASM acted like the function didn't even exist and it didn't know why. Because, somehow, the function ALSO lived on that Float32Array.

And because you're using WASM to be fast, you're typically trying to overwrite things that do O(N) operations or more. NO ONE is going to use this return a + b. One off functions just aren't worth programming in WASM. Worst of all, debugging this is often a matter of writing print and console.log statements everywhere, to try and 'eat' the whole array at once to find out what portion got corrupted or is broke. Or comment out your code line by line to see what in forsaken 9 circles of coding hell caused your problem. It's like debugging blind in a strange and overgrown forest of code that you don't even recognize because most of it is there to satisfy the needs of WASM.

And because it takes so long to debug, it takes a massively long time to create things, and by the time you're done, the dependent package you're building for has 'moved on' and find you suddenly need to update a bunch of crap when you're not even finished. All of this, purely because of a horribly designed technology.

And do they have sympathy for you for forcing you to update all this stuff? No. They don't owe you sympathy, and god forbid they give you any. You are a developer and so it is your duty to suffer - for some kind of karma.

I wanted to love WASM, but screw that thing, it's horrible errors and most of all, the WASM heap32.

Just wrote a brute-force attack simulation in c. Going to run it on actual hardware, with an 8-character limit, including alphabet (Upper and lower case), 0-9 and a few special characters and see if it gets done tonight ;)

I'll see you all in about 360 trillion operations.

Hi,
I'm not a ranty person so I never actually thought I'd post anything here but here it goes.

From the beginning.
We use ancient technologies. PHP 5.2, Symfony 1.2 and a non RFC complient SOAP with NO documentation.
A year ago We've been thrown a new temporary project. An VOIP app for every OS.
That being iOS, Android, MAC, PC, Linux, Windows mobile. With a 3 month deadline. All that thrown at 4 PHP developers. The idea being that They'll take it, sign the delivery protocol, everyone happy. No more updates for the app needed. They get their funds they needed the app for and we get paid.

Fast forward to today...

Our dev team started the year with great news that We'll most likely have to create a new project. Since the amount of new features would be far greater than current feature set, we managed to finally force our boss to use newer technologies (ie. seperate backend symfony4 PHP7+/frontend react, rest api and so on). So we were ecstatic to say the least. With preestimates aimed at a minimum 3 month development period. Since we're comfortable with everything that needs to be done.
Two days later our boss came to me that one of our most annoying clients needs a new feature. Said client uses ancient version written on a napkin because They changed half of the specification 2 weaks before deadline in a software made not by a developer but some sysadmin who didn't know anything. His MVC model was practically VVV model since he even had sql queries in some views. Feature will take 3 days - fixing everything that will break in the meantime - 1-2 months.
F*** it, fine. A little overtime won't kill me.
Yesterday boss comes again... Apparently someone lost a delivery protocol for a project we ended that half a year ago. Whats even better at the time when we asked for hardware to test we never got any. When we asked about any testing enviornment - nothing. The app being SEMI-stable on everything is an overstatement but it was working on the os'es available at the time. Since the client started testing now again, it turns out that both Android app does not work on 8.1/9 and the iOS app does not work on ios12. The client obviously does not want to pay and we can do little with it without the protocol, other than rewriting the apps.
It will take months at least since all of those apps were written by people that didn't know neither the OS'es nor the languages. For example I started writing the iOS one in swift. Only to learn after half of the development time, that swift doesn't like working by C Library rules and I had to use ObjC also. With some C thrown in due to the library. 3 unknown languages, on an unknown platform in 3 months. I never had any apple device in my hand at that time nor do I intend to now. I'm astonished it worked out then. It was a clusterf**k of bad design and sticking everything together with deprecated apis and a gum. So I'll have to basically fully rewrite it.

If boss decides we'll take all those at the same time I'll f***ing jump of a bridge.

At the age of 9, I was getting frustrated that my Commodore 64 didn't always respond the way I wanted. So I had to teach it to do better. BASIC was the language. Plenty of GOTOs. In the end I got so much connected to GOTO idiom that I used it extensively in my C++ OO exam in college. Needless to say, the professors were stunned and blatantly disgusted with my code.

Long rant...

*Designer Posted image of newly designed layout for our app on trello.

Dev 1 (me, being the junior, on ios) : so... What's the size for x, Y, z, a, B, C?

She: it's 9 for the small text, 10 for sub title, 12 for main title.

*shows her the design on app
Dev 1: seems too small

She: just make it to look not small.

Dafug?

*finishes the app layout for that screen.
*working on next screen

Dev 1: your new design is for the screen of 1920x1080. But our supported screen size starts from 320 width. So there'll be text overlapping each other and ui might screw up.

She: uh.. Just... Put those that will overlap to the next line.

*shrugs
Dev 1: ok
=======
2 days later
Dev 2 (senior, working on Android)
Dev 2: so... What's the colour for x, Y, z

*Dev 1 laughs on the inside because of the struggles we have with her.

Dev 1 to Dev 2: is it common for her not to follow the design guidelines?

Dev 2: yeah man.. We just have to adapt her design into our app guidelines.

*sigh

Dev 2: there's a new icon here on this screen, so you wanna change the icon? Can I have the icon file?

She: oh.. No.. Use back the old one, because I just copy and paste.

Dev 1: so... This progress bar of yours, doesn't show its background colour, because you filled it already. So what's the background colour if the bar isn't filled?

She : hmm.... Oh.. Well.. Maybe try x.. ? *doesn't look nice* how about Y? *doesn't look nice* how about...

Me : why not you try in your computer first instead of me changing it here by code, it's much faster this way.

*seriously, wth?

Dev 1 and 2: there's additional text in your new design, what is it for?

She : oh.. No no. I copied extra due to copy and paste. Just ignore it.

Dev 1 and 2: what's the spacing gap between x and Y? And how about the size of the box?

She : oh.. I just estimate it, and for the box, not sure either, you can follow old design, because I'm just putting a box there for illustration purpose.

Mother fickle, what fuck man.

Dev 1 and 2: *flips table.
*we didn't, but.. It's freaking annoying.

'Sup mates.
First rant...
So Here's a story of how I severely messed up my mental health trying to fit in university.

But the bonus: Found my passion.
Her we go,

Went to university thinking it'll be awesome to learn new stuff.
1st sem was pure shock - Programming was taught at the speed of V2 rockets.
Everything was centred around marks.

Wanted to get a good run in 2nd sem, started to learn Vector design, but RIP- Hospitalized for Staph infection, missed the whole sem and was in recovery for 3 months.
So asked uni for financial assistance as I had to re-register the courses the next semester. They flat out refused, not even in this serious of a case.

So, time to register courses for third semester, turns out most of the 2nd year courses are full, I had to take 3rd year courses like:
Social and Informational Networks
Human Computer Interaction
Image processing
And
Parallel and Distributed Computing (They had no prerequisites listed, for the cucks they are: BIG MISTAKE)
Turns out the first day of classes that I attend, the Image proc. teacher tells me that it's gonna be difficult for 2nd years so I drop it, as the PDC prof. also seconds that advice.

Time travel 2 months in: The PDC prof is a bitch, doesn't upload any notes at all and teaches like she's on Velocity-9 while treating this subject like a competition on who learns the most rather than helping everyone understand.
Doesn't let students talk to each other in lab even if one wants to clear their friend's doubt, "Do it on your own!" What the actual fuck?

Time for term end exams and project submission: Me and 3 seniors implement a Distributed File System in python and show it to her, she looks satisfied.
Project Results: Everyone else got 95/100
I got 76.
She's so prejudiced that she thinks that 2nd years must have been freeloaders while I put my ass on turbo for the whole sem, learning to code while tackling advanced concepts to the point that I hated to code.

I passed the course with a D grade.
People with zero consideration for others get absolutely zero respect from me.
Well it's safe to say that I went Nuclear(heh.. pun..) at this point, Mentally I was in such a bad place that I broke down.... Went into depression but didn't realise it.

But,
I met a senior in my HCI class that I did a project with, after which I discovered we had lots of similar interests.
We became good friends and started collaborating on design projects and video game prototyping.

Enter the 4th sem and holy mother of God did I got some bad bad profs....
Then it hit me
I have been here for two years, put myself through the meat grinder and tore my soul into shreds.
This Is Not Me
This Wont Be The End Of Me
I called up my sister in London and just vented all my emotions in front of her.
Relief.
Been a long time since I felt that.
I decided to go for what I truly feel passionate about: Game Design

So I am now trying to apply for Universities which have specialised courses for game design.

I've got my groove again, learnt to live again.
Learning C# now.
:)
It's been a long hello, and If you've reached till here somehow, then damn, you the MVP.
Peace.

Biggest challenge I overcame as dev? One of many.

Avoiding a life sentence when the 'powers that be' targeted one of my libraries for the root cause of system performance issues and I didn't correct that accusation with a flame thrower.

What the accusation? What I named the library. Yep. The *name* was causing every single problem in the system.

Panorama (very, very expensive APM system at the time) identified my library in it's analysis, the calls to/from SQLServer was the bottleneck

We had one of Panorama's engineers on-site and he asked what (not the actual name) MyLibrary was and (I'll preface I did not know or involved in any of the so-called 'research') a crack team of developers+managers researched the system thoroughly and found MyLibrary was used in just about every project. I wrote the .Net 1.1 MyLibrary as a mini-ORM to simplify the execution of database code (stored procs, etc) and gracefully handle+log database exceptions (auto-logged details such as the target db, stored procedure name, parameter values, etc, everything you'd need to troubleshoot database errors). This was before Dapper and the other fancy tools used by kids these days.

By the time the news got to me, there was a team cobbled together who's only focus was to remove any/every trace of MyLibrary from the code base. Using Waterfall, they calculated it would take at least a year to remove+replace MyLibrary with the equivalent ADO.Net plumbing.

In a department wide meeting:

DeptMgr: "This day forward, no one is to use MyLibrary to access the database! It's slow, unprofessionally named, and the root cause of all the database issues."
Me: "What about MyLibrary is slow? It's excecuting standard the ADO.Net code. Only extra bit of code is the exception handling to capture the details when the exception is logged."
DeptMgr: "We've spent the last 6 weeks with the Panorama engineer and he's identified MyLibrary as the cause. Company has spent over $100,000 on this software and we have to make fact based decisions. Look at this slide ... "
<DeptMgr shows a histogram of the stacktrace, showing MyLibrary as the slowest>
Me: "You do realize that the execution time is the database call itself, not the code. In that example, the invoice call, it's the stored procedure that taking 5 seconds, not MyLibrary."
<at this point, DeptMgr is getting red-face mad>
AreaMgr: "Yes...yes...but if we stopped using MyLibrary, removing the unnecessary layers, will make the code run faster."
<typical headknodd-ers knod their heads in agreement>
Dev01: "The loading of MyLibrary takes CPU cycles away from code that supports our customers. Every CPU cycle counts."
<headknod-ding continues>
Me: "I'm really confused. Maybe I'm looking at the data wrong. On the slide where you highlighted all the bottlenecks, the histogram shows the latency is the database, I mean...it's right there, in red. Am I looking at it wrong?"
<this was meeting with 20+ other devs, mgrs, a VP, the Panorama engineer>
DeptMgr: "Yes you are! I know MyLibrary is your baby. You need to check your ego at the door and face the facts. Your MyLibrary is a failed experiment and needs to be exterminated from this system!"

Fast forward 9 months, maybe 50% of the projects updated, come across the documentation left from the Panorama. Even after the removal of MyLibrary, there was zero increases in performance. The engineer recommended DBAs start optimizing their indexes and other N+1 problems discovered. I decide to ask the developer who lead the re-write.

Me: "I see that removing MyLibrary did nothing to improve performance."
Dev: "Yes, DeptMgr was pissed. He was ready to throw the Panorama engineer out a window when he said the problems were in the database all along. Didn't you say that?"
Me: "Um, so is this re-write project dead?"
Dev: "No. Removing MyLibrary introduced all kinds of bugs. All the boilerplate ADO.Net code caused a lot of unhandled exceptions, then we had to go back and write exception handling code."
Me: "What a failure. What dipshit would think writing more code leads to less bugs?"
Dev: "I know, I know. We're so far behind schedule. We had to come up with something. I ended up writing a library to make replacing MyLibrary easier. I called it KnightRider. Like the TV show. Everyone is excited to speed up their code with KnightRider. Same method names, same exception handling. All we have to do is replace MyLibrary with KnightRider and we're done."
Me: "Won't the bottlenecks then point to KnightRider?"
Dev: "Meh, not my problem. Panorama meets primarily with the DBAs and the networking team now. I doubt we ever use Panorama to look at our C# code."

Needless to say, I was (still) pissed that they had used MyLibrary as dirty word and a scapegoat for months when they *knew* where the problems were. Pissed enough for a flamethrower? Maybe.

Now I get to use records and can use all that fancy syntactic sugars.
Life's good.

Im so frustrated with myself . I've always been afraid of being stupid . Perhaps it was because i was always called the "less intelligent" sibling by my parents . Well i did self-learn java , c++ and android (when i was 15) and made some apps and i did get acknowledged finally but i may have not acknowledged myself . I got into college a couple years ago and i can tell you right out that its like an island filled with stupidity. The teachers , the students. The other day i caught my teacher learning how a transistor works. This is unacceptable for someone who is teaching us advanced op-amps and other circuits . Well , I did get into this college cause it was less tedious and i thought college doesn't matter cause i can self-learn . All i needed was free time . Well college totally destroyed that too and provided no facilities in the process as well . So yeah should i blame my college for my inability to do things the past couple years. I mean i don't think i've learnt a single thing all this while. This is where my frustration begins cause i dont want to blame the college , it's not going to help me and i'll probably end up in a 9 to 5 call center job at this rate . Im also very heavily frustrated with myself , it's like everything i've done so far has been a path of least effort. I have tried a few things which were all just fads like machine learning and crypto and even trading . They felt good and thats what scares me , maybe i don't have the passion and am just looking for a quick buck . This is clearly reflected in the ideas i've been having as well . Well i've never had access to proper funds but now im just trying to justify this layman emotion . I just want to learn and be passionate about learning , researching and i just want enough funds for that . But im afraid , maybe its just that i want to feel superior than my circle . I mean i still don't know why i tried learning rust and wasted even more time setting up fedora and everything around it while i already had a working debian setup and a programming language i'm kind of versed with . i wouldn't say well cause im a self learner and i feel guilty for that . I definitely know i just learnt the surface of the language . Deep down i'm just another stupid fad obsessed guy who feels better by choosing a more complex language that my colleagues look upto . Is this what i am , if so im scared and i don't know what to do . People say that you are what you are and you cant change that . If i cant change this then i dont deserve this wasteful stupid life . I don't know what i should do and it makes me cry . Maybe acknowledging this would've helped but it hasn't , I've felt better playing fortnite rather than learning some basic electronics. Im another one of those aren't I ?

I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3

Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.

I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.

So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.

So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.

That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3

Microshaft WanBLowS.

I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.

Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.

At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.

So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.

Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.

That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.

(looks like my rant is too long, continue in comments)

I've never used Windows in my day-to-day life. No kidding.
When I got my father's first computer, I used an old distribution called BBC Linux. I didn't have any computer knowledge, it was my first contact with a computer, so I went to a friend's house and asked for a CD to install on my computer. I don't know if this friend ended up making a "gotcha" and thought I'd give up, but I just read the manuals and fell in love. That was year 2000.
Then I used Conectiva Linux, then I went to Red Hat 9, then Slackware, then in 2007 I started using Solaris. And I stayed on Solaris (Solaris 10, Solaris Nevada and OpenSolaris) until 2011.
In 2011 I bought a Mac. I stayed at Apple until 2020, when I couldn't stand Apple forcing me to buy new computers (I still don't understand how a 2011 iMac, i5 (4 Hyper Thread cores) with 16GB of RAM, 1TB SSD only runs up to High Sierra).
Then I bought a Dell. It came with Windows 10, the first thing I did was install WSL2. I could not stand it, the system is bad, sorry. I installed OpenSuse and have been using it for two years.

It's just that every day someone tells me "how can you use this"? "There is no alternative to Windows, do you want to be different?"

I know that my story was the reverse of the "mainstream", so I'm going to talk about my vision of Windows, that in my brain it is actually the "alternative".

- Having a file explorer without "tabs" in 2022 is unthinkable for me.
- I love terminal. And the Windows terminal is very limited. "ps ... | awk ... | xargs ..." is a must for me. "find ./ -name '...' -exec ..."... these things on Windows are totally "different" and have the "powershell way" while all other operating systems keep the same form. And cygwin is not an option. As Wine for serious work is also not.
- Dragging a file into the terminal, and having it write its path, is so natural, that when Windows didn't do it, I was dismayed.
- I've always used StarOffice, OpenOffice and now LibreOffice. All the people in my story received my documents and reports as a PDF and no one complained. Until a coworker saw me editing in LibreOffice and said "oh I want it in word format". As long as he didn't know, everything was fine, right?
- Windows is paid. And is there advertising? I don't understand. And I refuse. If you want to display advertising, then excuse me. I have no problem paying, I'm not an opensource shiite. It's just that paying and not working bothers me much more than an opensource that I can fix or expect a fix knowing the good will of the people involved.
- Hyper-V is a joke. QEMU/KVM is better, and Bhyve on FreeBSD which is a very young project, is already a million times better than Hyper-V.
- Developing in C/C++ for Windows is only possible in two ways: Either you've always lived in Windows and your brain is conditioned, or you compile with MSYS2 (CLang or GCC).
- There is no significant evolution of the windows desktop since 95.
- Multiple workspace support with multiple monitors, not ready. It's another joke.
- REGEDIT does not need any comment.
- The system loses performance over time. I still don't know how Windows achieves this.
- I've seen people complain about desktop fragmentation on Unix and Linux. Many DEs end up leaving applications with different themes (like running a Qt application in Gnome and GTK in KDE), but to be quite honest, the lack of Windows standard bothered me much more. Even Microsoft's own software is completely different: Control Panel, Calculator, Paint and Office, To-Do, and Settings, have horrible style differences and look-and-feel fragmentation.
- Dark mode has not been implemented. It's another joke. Many applications are white while everything else is dark. Sorry, even on Linux which is a mess, this has been resolved. And well resolved.
- NTFS? Serious?
- C:, D:.. It doesn't convince me since DOS.
- Bloatware.
- News "biased" in the search bar is a lack of respect for those who use the computer to work.

And that. For me, Windows is the alternative operating system. I can't take Windows seriously, for me it's an experimental one like Haiku or ReactOS. It's good to play.

About market share, it doesn't convince me to use it. But convinces me to sell. I've always developed applications to run on Windows. And when I need it, I turn on a VM to compile the project. But in everyday life? Impractical.

The new holy war in C#:

Point p = new Point(5, 3);

vs.
var p = new Point(5, 3);

vs. (new)
Point p = new (5, 3);

and... FIGHT!!

My first contact with a computer was in 1997, I was close to 9.
My parents bought it together with a 17" screen and a color inkjet for about 6000.- CHF if I remember it correctly.
It had Windoozle 95, Pentium 2 233MHz, Radeon Rage 128 something.
At first I was not allowed to use it, but after watching them write documents for some time, they allowed me to draw random stuff in MS Paint and use Word.

It did't take long until I figured out to do more stuff on the system.
I think I crashed Windows a few times by installing some random demo software or shareware and execute just anything to see what happens.

When I turned 10, my godmother gave me Age Of Empires 2 as a present (I wished it so badly) and since this gift, I was somewhat addicted with computers and gaming.

My mother forbid me a lot of times to use the computer for weeks. 😄

But it all made me know computers better and even start programming with Quick Basic! (later VB, C++ and C#)

So.... yeah, making a Scratch clone (with more features) is frustrating and super hard.

Major problems include
- Drag&Drop from listbox to usercontrol - stress level : 3/10
- connect blocks when two blocks are close to each other - stress level : 10/10
- generate live code when there was a change in blocks editor - stress level : 9/10
- write a compiler or some interpreter that converts block code to real c# code - stress level : 10/10
- generate output by calling csc.exe - stress level : 1/10
- make code at least readable - stress level : 7/10

How I got selected for GSoC'19:
I will describe my journey from detail i.e from the 1st year of the college. I joined my college back in 2017 (July), I was not even aware of Computer Science. What are the different languages of CS, but I had a strong intuition of doing BTech from CSE only?

So yeah I was totally unaware of the computer science stuff, but I had a strong desire to learn it and I literally don’t know why I had this desire. After getting into college, I was learning HTML, Python, and C, also I am really thankful to my friends who really helped me to learn, building logic and making stuff out of it. During the 1st month of joining the college, I got to know what is Open Source, GSoC, Github due to my helpful seniors. But I was not into Open Source during my 1st year of college as I thought it is very difficult to start. In my 1st year, I used to do competitive programming and writing scripts in Python to automate various stuff. I never thought that I would even start doing Open Source development, also in the summer vacations after the 1st year I used to practice programming on HackerRank and learnt an awesome course called Automate the Boring Stuff with Python(which I think is one of the most popular courses for Python) which really helped me to build by Python skills.

Now the 2nd year came, I was totally confused between doing Open Source development or continue with my Competitive programming. But I wanted to know about Open Source development, so I thought to start now will be a good idea. I started attending meetups of OSDC(Open Source Developers Club) which is a hub of my college, which really helped me to know more about Open Source development from my seniors. I started looking for beginner friendly projects in Python on the website Up For Grabs, it’s really helpful for the beginners. So I contributed in a few of them, and in starting it was really tough for me but yeah I continued, which really helped me to at least dive into Open Source. Now I thought to start contributing in any bigger project, which has millions of lines of code which will be really interesting. So I started looking for the project, as I was into web development those days so I thought to find a project which matches my domain. So yeah I finally landed on Oppia:
Oppia

I started contributing into Oppia in November, so yeah in starting it was really difficult for me to solve any issue (as I wasn’t aware of the codebase which was really big), but yeah mentors at Oppia are really helpful, they guided me which really helped me to start my journey with Oppia. By starting of January I was able to resolve around 3–4 issues, which helped me to become the collaborator at Oppia, afterward I really liked contributing to it and I was able to resolve around 9–10 issues by the end of February, which landed me to become a Team Member at Oppia which was really a confidence boost and indication for me that I am in the right direction.

Also in February, the GSoC organizations list was out, and yeah Oppia was also participating in it. The project ideas of Oppia were really interesting, I became even confused to pick anyone because there were 4–5 ideas which seemed interesting to me. After 1–2 days of thought process I decided to go for one of them, i.e “Asking students why they picked a particular answer”, a full stack project.

I started making proposals on it, from the first week of March. I used to get my proposal reviewed frequently from the mentors, which really helped me to build a good and strong proposal.

I must say a well-defined proposal is the most important key for getting selected in GSoC, also you must have done some contributions to the organization earlier which I think really maximize your chances of selection in GSoC.

So after my proposal was made, I submitted it on the GSoC website.
Result Day:

It was the result day, by the way, I had the confidence of being selected, but yeah I was a little bit nervous. All my friends were asking when is your result coming, I told them it will come at 12.30AM (IST). Finally, the time came when I refreshed the GSoC website, Voila the results were out. I opened the Oppia organization page, and yeah my name was there. That was the day I was really happy and satisfied, I was thinking like I have achieved something in my life. It was a moment of pleasure for me, I called my parents and told them my result, they were really happy for me.

I say cracking GSoC is worth it, the preparation you do, the contributions you do, the making of the proposal is really worth.

I got so many messages from my juniors, friends, and seniors, they congratulated me. After that when I uploaded my result of Facebook and LinkedIn, there were tons of comments and likes on the post. So yeah that’s my journey.

By the way, I am writing this post after really late, sorry for it. I must have done it earlier, but due to milestone 1 of GSoC, I was busy.

I just started as a computer science major, and I'm a little irritated because I think I know more than my proffessor. I was excited that I would be pushed to my limits, but the other day I asked him for things I should work on to get ahead...
Him: Sure, page 475 has some good projects. Just don't go past chapter 9 unless you're confident with pointers.
Me: I did C before C++ and I hated pointers.
Him: C doesn't have pointers, you must have been using a different version of C.
Me: OK
Like really? I just can't wait till next semester.

At 9, I wanted to create a video game, I learned how to use RPG Maker, then Ruby with RGSS then C, then HTML, CSS... And now I'm here, 9 years later :p

I want to share one very interesting incident -
Once upon a time, ( 9 yrs back ) I got my first PC. It had Windows XP.
After using it for 1.5 hours, I realised there are some files in C:
I said to myself, my hard disk capacity is 150GB but why some files exist in C:?
Within next 4 seconds, I issued a command to delete all files in C:
The rest you can predict :p

Ok. question:

should I learn Java or not?

I come from a C++ background and would (obviously) like to know, wether I need Java in my career. I already have some pretty neet projects like a selfmade "compiler" , Im currently building a chess engine that doesnt brute force.

An alle deutschen:
Kann jemand mir sagen, wie ich als 9. Klässler einen nachmittagsjob (bestenfalls homeworking) bekommen könnte? Es geht mir nicht um das Geld, sondern um die Erfahrung und die sicherheit, schon einmal etwas VOR dem Abi in der Hand zu haben

Unreal Engine SDLC:
1. Start Epic
2. Wait
3. Start Unity
4. Wait
5. Open Project
6. Wait
7. Wait more
8. a bit longer...
9. (it usually crashes here, or freezes, in which case go to 1)
10. Game opened, make modifications in C++ codes
11. Wait VS to load
12. Wait VS to parse all the file in solution
13. Make changes
14. Compile
15. Run from Unreal
16. (sometimes, go to 9)
17. Goto 9
18. 9
19. Goto 9
20. Congrats on finishing the game, and losing your patience

TLDR;
How much do you earn for your skill set in your country vs your cost of living?
BONUS;
See how much I & others earn.

Recently I became aware of just how massive the gap in developers earnings are between countries. I'd love to calculate a fixed score for income vs cost of living.

I know this stuff is sensitive to some so if you prefer just post your score (avg income p/m after tax / cost of living).

I'm not shy so I'll go first:

MY RATES
Normal Rate (Long term): $23
Consulting / Short term: $30-$74
Pen Test: $1500 once off.
Pen Test Fixes: consulting rate.
Simple work/websites: min $400+
Family & Friends: Dev friends are usually free (when mutually beneficial). Family and others can fuck off, even if they can pay (I pass their info to dev friends with fair warning).

GENERAL INFO
Experience: 9 years
Country: South Africa
Developer rareness in country: Very Rare (+-90 job openings per job seeker).
Middle class wage in country: $1550 p/m (can afford a new car, decent apartment & some luxuries like beer/eating out).
Employment type: Permanent though I can and do freelance occasionally.
Client Locality: Mostly local.
Developer Type: Web Developer (True web dev - I do anything web related from custom HTTP servers to sockets, services, advanced browser api's, apps & more).

STACKS / SKILLSETS

I'M PROFICIENT IN:
python, JavaScript, ASP classic, bash, php, html, css, sql, msql, elastic search, REST, SOAP, DOM, IIS, apache

I DABBLE WITH:
ASP.net, C++, ruby, GO, nginx, tesseract

MY SPECIALTIES:
application architecture, automation, integrations, db's, real time data, advanced browser apps/extensions (webRTC, canvas etc).

SUMMARY
Avg income p/m after tax: $2250
Cost of living (car+rent+food): $1200
Score: 1.85

*Note: For integrity when calculating my cost of living I excluded debt repayments and only kept my necessities which are transport, food & shelter.

I really hope you guy's post your results, it would be great to get an idea of which is really the worst / best country to be a developer in.

It's been a while DevRant!

Straight back into it with a rant that no doubt many of us have experienced.

I've been in my current job for a year and a half & accepted the role on lower pay than I normally would as it's in my home town, and jobs in development are scarce.

My background is in Full Stack Development & have a wealth of AWS experience, secure SaaS stacks etc.

My current role is a PHP Systems Developer, a step down from a senior role I was in, but a much bigger company, closer to home, with seemingly a lot more career progression.

My job role/descriptions states the following as desired:

PHP, T-SQL, MySQL, HTML, CSS, JavaScript, Jquery, XML

I am also well versed in various JS frameworks, PHP Frameworks, JAVA, C# as well as other things such as:

Xamarin, Unity3D, Vue, React, Ionic, S3, Cognito, ECS, EBS, EC2, RDS, DynamoDB etc etc.

A couple of months in, I took on all of the external web sites/apps, which historically sit with our Marketing department.

This was all over the place, and I brought it into some sort of control. The previous marketing developer hadn't left and AWS access key, so our GitLabs instance was buggered... that's one example of many many many that I had to work out and piece together, above and beyond my job role.

Done with a smile.

Did a handover to the new Marketing Dev, who still avoid certain work, meaning it gets put onto me. I have had a many a conversation with my line manager about how this is above and beyond what I was hired for and he agrees.

For the last 9 months, I have been working on a JAVA application with ML on the back end, completely separate from what the colleagues in my team do daily (tickets, reports, BI, MI etc.) and in a multi-threaded languages doing much more complicated work.

This is a prototype, been in development for 2 years before I go my hands on it. I needed to redo the entire UI, as well as add in soo many new features it was untrue (in 2 years there was no proper requirements gathering).

I was tasked initially with optimising the original code which utilised a single model & controller :o then after the first discussion with the product owner, it was clear they wanted a lot more features adding in, and that no requirement gathering had every been done effectively.

Throughout the last 9 month, arbitrary deadlines have been set, and I have pulled out all the stops, often doing work in my own time without compensation to meet deadlines set by our director (who is under the C-Suite, CEO, CTO etc.)

During this time, it became apparent that they want to take this product to market, and make it as a SaaS solution, so, given my experience, I was excited for this, and have developed quite a robust but high level view of the infrastructure we need, the Lambda / serverless functions/services we would want to set up, how we would use an API gateway and Cognito with custom claims etc etc etc.

Tomorrow, I go to London to speak with a major cloud company (one of the big ones) to discuss potential approaches & ways to stream the data we require etc.

I love this type of work, however, it is 100% so far above my current job role, and the current level (junior/mid level PHP dev at best) of pay we are given is no where near suitable for what I am doing, and have been doing for all this time, proven, consistent work.

Every conversation I have had with my line manager he tells me how I'm his best employee and how he doesn't want to lose me, and how I am worth the pay rise, (carrot dangling maybe?).

Generally I do believe him, as I too have lived in the culture of this company and there is ALOT of technical debt. Especially so with our Director who has no technical background at all.

Appraisal/review time comes around, I put in a request for a pay rise, along with market rates, lots of details, rates sources from multiple places.

As well that, I also had a job offer, and I rejected it despite it being on a lot more money for the same role as my job description (I rejected due to certain things that didn't sit well with me during the interview).

I used this in my review, and stated I had already rejected it as this is where I want to be, but wanted to use this offer as part of my research for market rates for the role I am employed to do, not the one I am doing.

My pay rise, which was only a small one really (5k, we bring in millions) to bring me in line with what is more suitable for my skills in the job I was employed to do alone.

This was rejected due to a period of sickness, despite, having made up ALL that time without compensation as mentioned.

I'm now unsure what to do, as this was rejected by my director, after my line manager agreed it, before it got to the COO etc.

Even though he sits behind me, sees all the work I put in, creates the arbitrary deadlines that I do work without compensation for, because I was sick, I'm not allowed a pay rise (doctors notes etc supplied).

What would you do in this situation?

Do you have any annoying you want to get rid off, but you can't because of reasons?
I do. They are 4, but for now I'll talk about the gold medal winner.

When we met about 8-9 ago, she had just come back to town due to some very bad personal experience (not her fault). Anyway, she is polite, but her major flaw is that she is pushy. REAL BAD! And she gets mad when other people (including me) try to do it on her. Another one is having calls during random inappropriate times, because she had fight #N with her boyfriend, and last but not least, she will call when needs something out of someone.

Lately, her project is finding us a job, since we're both unemployed. Any job. The sad part is when she sends me job ads for dev jobs I don't qualify, e.g. Company X is looking for a dev with Y year of experience, knowing A, B, C & D technologies. I've told her that I don't qualify for most of the dev jobs she sends me, but she insists I should send my CV anyway, cause of reasons. Also, for some reason, I should be accounted to her for all my current choices when what I would honestly say is "BUG OFF".

Her latest endeavour is getting me one of her friends (a psychologist) as a "client". Her friend wants to have a professional website with writing posts/articles as a side dish. I'm not registered as a freelancer, so everything will be done under the counter, and her friend is OK with that. I'm no web developer, but I didn't refuse because of her backlash and also that would be a positive experience for me. Now, the juicy part. She gave her my phone number without my permission and she told me straight away. Her plan was having the three of us meet, though I don't know why and I didn't want her being around. I asked her to call me immediately, which it didn't happen. After being pestered by my friend for a couple of weeks if her friend called me, she finally did it on Monday. She didn't say to me anything I didn't know, but at least I have her phone now.

What I can offer her is a website skeleton with the usabilities she's asking. What I can't offer her is graphics/banner and security. And now I have to come up with reasonable price. Teams here ask 400-600€ for a complete website the way she asks, including VAT. I'm thinking around 100€ and I don't know when I can deliver the project. I've had some experience with Ruby and Sinatra, so I'll go with that, and I'll learn CSS along the way.

Thanks for reading till the end! 😃

Wrote my first programs on my Commodore C64.
First program was a number guessing game where you needed to guess a number between 1 and 100. Shit had 300+ lines because I only new the if clause and the equals comparison.
I was 9.

Later a friend showed me Modula 2 and I was instantly in love with that language.

Real programming then in school (C, C++, µC assembler).

!rant just a question. Sorry in advance for the long post.

I've been working in IT in Windows infrastructure and networking side of things for my entire career (5years) and recently was hired for a role working with AWS.

We use Macs and we use *nix distros for days. I've only ever dabbled for 'funsies' before with Linux because every previous job I held was a Windows house and f*** all else.

I'm just wondering if anyone here might have some insights as to a great way to learn the Linux environment and to learn it the right way. I'm not the best Windows admin ever and will never claim to be, but I have seen stuff that other people have done that makes me want to swing a brick at someone's head. And I feel that with all of the setup wizards and the "We'll just do it for you." approach that Windows has used since forever it allowed enough wiggle room for people that didn't know what they were doing to f*** sh*t up royally. I'm not familiar enough with Linux to know if this is also a common problem. I know that having literal full-access to every file in your OS can cause a n00b like myself to mess up royal, thus the question about learning Linux the right way.

I vaguely understand the organization of the folders and file structure within Linux, and I know some very basic commands.

sudo rm -rf /*
Just kidding

But All of my co-workers at my new job are like mighty oaks of knowledge while I'm a tiny sapling. And at times I've been intimidated by how little I know, but equally motivated to try and play catch-up.

In addition to all of this, I really want to start learning how to program. I've tried learning multiple times from places like codecademy.com, YouTube tutorials, and codeschool.com but I feel like I'm missing the lesson that explains why to use a certain operation instead of another. Example: if/else in lieu of a switch.

I'm also failing to get the concept of syntax in certain languages I've tried before. Java comes to mind real fast.

The first language I tried teaching myself was C++ from YouTube. I ended up having a fever dream that night about coding and woke up in a cold sweat. Literally, like brain overload or something. I was watching tutorials for like 9 hours straight.

Does anyone know of a training resource that will explain, in terms a 5 year old would understand, what the code is doing and why? I really want to learn but I'm starting to lose steam cause I'm just not getting it.

Thank you in advance for any tips guys and gals. I really appreciate it. Sorry for the ridiculously long questions.

"Our app needs a barcode scanner"
Fair enough, let's do this!
Android implementation using Zxing: 3 days. Ios: 9 days...
1. Dev iPhone has a subtle hw defect that doesn't let it connect to the computer anymore...
2. Our app-framework doesn't have a proper plugin for ios barcode scanners yet.
3. The first barcodescanner implementation is completely broken
4. Swift is not possible because of conflicting framework plugins
5. Build a plugin from scratch, using zxing objective c port.
6. Build problems with main app.
7. Fuck my life

"Reflective" programming...

In almost every other language:
1. obj.GetType().GetProperties()
or
for k, v in pairs(obj) do something end
or
fieldnames(typeof(obj))
or
Object.entries(obj)

2. Enjoy.

In C++: 💀
1. Use the extern keyword to trick compilers into believing some fake objects of your chosen type actually exist.

2. Use the famous C++ type loophole or structured binding to extract fields from your fake objects.

3. Figure out a way to suppress those annoying compiler warnings that were generated because of your how much of a bad practice your code is.

4. Extract type and field names from strings generated by compiler magic (__PRETTY_FUNCTION__, __FUNCSIG__) or from the extremely new feature std::source_location (people hate you because their Windows XP compilers can't handle your code)

5. Realize your code still does not work for classes that have private or protected fields.

6. Decide it's time to become a language lawyer and make OOPers angry by breaking encapsulation and stealing private fields from their classes using explicit template instantiation

7. Realize your code will never work outside of MSVC, GCC or CLANG and will always be reliant on undefined behaviors.

8. Live forever in doubt and fear that new changes to the compiler magic you abused will one day break your code.

9. SUFFER IN HELL as you start getting 5000 lines worth of template errors after switching to a new compiler.

I was propably 15 years old the first time i saw my friend coding html and and other related stuff i cannot remember! It intriqued me and i really wanted to learn it (i wanted to learn to hack.. xD..) but at the given time i wasn't happy in life and i was pretty much addicted to WoW..

So.. forward 12 years, where i had gone to the military, thought about becoming a physiotherapist, psychiatrist, korean translator and game designer.. oh and countless attempts from another friend to get me interested in c#.. i decided to start studying computers (software/hardware) at DTU (danish university).

That was rougly 8-9 months ago and i am now pretty decent in C, HTML, C++, Java, MySQL and koncepts about networks and OOP designs :).

I am super grateful to all the trial and errors throughout my life that have brought me to this place :)

Still 27, still has alot to learn, but i am really happy where i am right now. Even so, that i am spending my free time making my own projects :)

I also get super happy whenever i fix a bug of mine :p.

I truly believe that you will skyrocket to succes if you do what you love.

For me, i just discovered that part of myself a little late :)

Not sure what i hope to achieve with this post, but i hope it can give an insight into what people go through and yeah.. go for what you want!

Have a great time everyone!

And first !rant on this app!
I love all your rants! vs !rants

I see your C# 9 and raise you 2005

Compilers should just work for raw C with only static memory allocation. This isn't the bad old days where a couple of dudes wrote a short book explaining how C might probably should possibly work. I hear supposedly we have standards now.

Well, last week I lost 2 days to our compiler randomly forgetting that it wasn't okay to put a globally allocated uint32 at an address ending in 9. What? It had been handling this case without issue for more a year, but now after changing completely unrelated code we have this problem.

I'm not sure how to even deal with this idiocy so no doubt I'll continue working on it this week, too.

Thanks a lot, GCC.

If languages had slogans...

1) Java -- Buy one get two for free on your delicious NPEs.

2) C -- I burn way too much calories talking, let's do some sign language. Now see over there... 👉

3) Python -- Missing semi-colon? Old method. Just add an extra space and watch the world burn.

4) C++ -- My ancestors made a lot of mistakes, let's fix it with more mistakes.

5) Go -- Meh. I can't believe Google can be this lazy with names.

6) Dart -- I'm the new famous.

7) PHP -- To hide your secrets. Call us on 0700 error_reporting(0)

8) JavaScript -- Asynchronous my ass!

9) Lua -- Beginners love us because arrays start at 1

10) Kotlin -- You heard right. Java is stupid!

11) Swift -- Ahhh... I'm tasty, I'm gonna die, someone please give me some memory.

12) COBOL -- I give jobs to the unemployed.

13) Rust -- I'm good at garbage collection, hence my name.

14) C# -- I am cross-platform because I see sharp.

15) VB -- 🙄

16) F# -- 😴

I'm wondering.. Chinese have built all sorts of things we never knew we need in our lives. I'm wondering, is there anywhere a physical smartphone keyboard I could purchase? The old-school numpad, like on nokia 3310 or so.

I sometimes find myself in situations where I'd like to type the whole message w/o looking at the screen. Touch-keyboards make this an impossible goal. Having an old-school physical kbd would be perfect for the job!

Finally done with school. It were three years of ups and downs.

The downs were plenty and mostly in the way school material was organized.

We've spend years learning web development where the course should have been more broad (application development)

So by the time my first internship period of half a year approached I searched for a company outside of web development and ended up at a company which did serious games using unity C#. Those were the best months of my 3 years. I managed to push the company into a direction for a future even though it was reletively small.

After that I took up .net and got the MTA C# Fundamentals certificate from microsoft itself. (School offered the exam).

Then there was the 2nd internship.
Worked for a company who sold intranets to other enterprises and I developed a mobile app which connected a user's phone to their account on their intranet. Allowing to seperate work and their private life.

That project was fun but the company itself was terrible. 4 people at the office and the owner treated us as objects rather than people. The company was too small for such an environment and most of them were irritated 9 times out of 10. Glad to be rid of them.

Now I'm in the process of looking for a job and have a meeting with a recruiter tomorrow

Wish me luck.

guide to make successful software house company for future me:

1.find shortest domain name with code / star / best / it / super / ai / - whatever banger word you find
2. parse companies work board / linkedin jobs
3. parse people profiles
4. setup email server and create fake linkedin profiles that match jobs and candidates so company looks big
5. fake c-level management so company looks big
6. spam likes and create posts generated by ai from multiple profiles
7. spam invitations to people that match job descriptions and to people working within companies posting jobs
8. offer fake candidates that match job description
9. find real but less promising candidates and offer them the job
10. tell that fake candidate is no longer available but you have someone better

The most I have worked on something is 14 hours. It was for a university project, that involved creating a "banking" app that was intended to demonstrate the use of an SQL database. I had a partner, and we had done nothing about the project until the previous day. We started working at 5 PM and the demonstration was at 12 PM (noon) in the next day. We used PostgreSQL for the database, and C# and Windows forms for the GUI. My partner took on the database creation and I took on the GUI. I had minimal experience with C# and had never worked with Windows forms or DB bridging in a program. On top of it, lack of sleep hits me really hard, so by midnight I was just like a zombie with near zero focus capacity. As a result, I ended up rewriting numerous components with identical logic and appearance and some different elements that could be parameterized, simply because organizing my thoughts to write proper code was out of the question in my condition. The writing, debugging, testing and packing of the project ended at 7 AM, the morning of demonstration. I slept for 3 hours and then met with my partner and headed to uni. I never left a project for the last moment again. We ended up taking a 9/10 grade.

Have you ever written a very complicated code to look like a professional programmer??

For example:hello world app in c++

#include <iostream>
using namespace std;

int main(int argv, char argc)
{
char vhWnd[] = new char[13];

struct dataentry
{
string txt;
float vex = 0.2345234;
};

vhWnd[1] = 'e';
vhWnd[4] = 'o';
vhWnd[3] = 'l';
vhWnd[2] = 'l';
vhWnd[7] = 'o';
vhWnd[5] = ' ';
vhWnd[6] = 'W';
vhWnd[9] = 'l';
vhWnd[8] = 'r';
vhWnd[13] = '\0';
vhWnd[10] = 'd';
vhWnd[12] = '!';
vhWnd[11] = ' ';
vhWnd[0] = 'H';

for ( int i = 0, i=13, i++)
{
nhttp << vhWnd[i];
}

return 85037593;
}

I just got the dna test.
I am the father. My daughter is now 3 weeks old.

No surprise there. I expected to be the father. I had no reason to distrust my wife. But, after all, I know my IT security.

The relationship I had with my daughter was transitive. I trusted my wife and my wife had my daughter, ergo I had a connection with my daughter. Or in clearer terms: from a => b and b => c follows a => c.

The problem I was thinking about: What if I will stop trusting my wife in the future. At some point in the future... Something might happen. And I would stand there and wonder how long it went on. Maybe a month? Or before my daughter's birth? Maybe more than 9 month before my daughter. Would I be able to hide it from my daughter or would she notice...

If anything ever happens now, I know it has nothing to do with my daughter...

That's the same reason why we use end2end encryption. Sure, we have to trust that the application provided is not manipulated. But we only have to trust today. If it lands on their severs, we have to trust until the end of eternity.

I don't need any trust right now. And I am fucking happy about it.

Worked as a swift ios developer for 2years now, boycotted java (android) and objective-c alltogether.
Have to do both plus javascript because my cto is marvelled by the promises of react-native...
The damn guy doesn’t have to implement a single line of code ! I do !
As if having to dev on xcode 9 wasn’t bad enough already 👏👏

I have this specific friend who says he doesn't have time to learn C++ to pass project labs in uni.. but 2 days later messages me drunk from a bar saying he have been drinking for past 9 hours.

I started coding as soon as year 5 of school. It was more learning how to write algorithms at first. This gave me the necessary grounds for being able to solve complex problems in my head by splitting them up. Actual programming started out in year 9 when I first met Pascal, younger programmers probably don't even know what it is(I'm 20 and I say that) 😂. Then I moved on to C and C++ in the following year and that made me realise that all languages are really similar.

Honestly speaking, I don't understand all these homes about Java programmers not being able to C#.

I'm mainly a Java programmer and about 9 months ago, my team inherited a huge scope of applications developed in C#. I was forced to learn C# in order to support those applications and I have to say I didn't find the language that difficult...

We got this feature on our app where if you change the status of an action item, it moves down/up to join its brethren of the same status at the bottom of its respective grouping. This is also true for creation.

Problem is: Testing.

I embarked upon this fuckin ridonkulousness today where I had to test all possible scenarios. Empty list, list with only A status, list with only B, list with A and B, list with A and C, etc etc

9 fucking hours later and a lot of anger, I am finally done. I powered back probably 10 club sodas, 6 teas, and had chillstep rollin all day.

If y'all ever feel like giving up because shit's hard, keep pushin. You'll get it eventually ;)

I am a beginner in programming. Started to code some 9 months back. So far I have learnt some basic C, Python(from LPTHW), HTML, CSS, JavaScript(from Coursera). I want to advance my skill. One of my relatives who is a programmer too advices me to learn SQL now and then learn PHP. So according to you what should I do now. I also want to develop my Python skills to using its frameworks so that I can make some real stuffs with that.

Pls suggest me my next move and also tell me from where can I learn these things( free courses could be of more help to me). I want to quickly learn the most of these so that I can make a dynamic website and web apps in the near future.

Thanks in advance!

Persisterising derived values. Often a necessary evil for optimisation or privacy while conflicting with concerns such as auditing.

Password hashing is the common example of a case considered necessary to cover security concerns.

Also often a mistake to store derived values. Some times it can be annoying. Sometimes it can be data loss. Derived values often require careful maintenance otherwise the actual comments in your database for a page is 10 but the stored value for the page record is 9. This becomes very important when dealing with money where eventual consistency might not be enough.

Annoying is when given a and b then c = a + b only b and c are stored so you often have to run things backwards.

Given any processing pipeline such as A -> B -> C with A being original and C final then you technically only need C. This applies to anything.

However, not all steps stay or deflate. Sum of values is an example of deflate. Mapping values is an example of stay. Combining all possible value pairs is inflate, IE, N * N and tends to represent the true termination point for a pipeline as to what can be persisted.

I've quite often seen people exclude original. Some amount of lossy can be alright if it's genuine noise and one way if serving some purpose.

If A is O(N) and C reduces to O(1) then it can seem to make sense to store only C until someone also wants B -> D as well. Technically speaking A is all you ever need to persist to cater to all dependencies.

I've seen every kind of mess with processing chains. People persisting the inflations while still being lossy. Giant chains linear chains where instead items should rely on a common ancestor. Things being applied to only be unapplied. Yes ABCBDBEBCF etc then truncating A happens.

Extreme care needs to be taken with data and future proofing. Excess data you can remove. Missing code can be added. Data however once its gone its gone and your bug is forever.

This doesn't seem to enter the minds of many developers who don't reconcile their execution or processing graphs with entry points, exist points, edge direction, size, persistence, etc.
