I think the weekly rants just exist because @dfox & @trogus got banned from stackoverflow and they still have questions.

When it comes to learning cutting edge tech... Go build already!

I found Rust intimidating.

I read the first few pages of the official book, got bored, gave up.

Few months later, decided to write a "simple" tool for generating pleasing Jetbrains IDE color schemes using Rust. I half-finished it by continuously looking up stuff, then got stuck at some ungoogleable compiler error.

Few months later I needed to build a microservice for work, and against better judgement gave Rust a try in the weekend. Ended up building an unrelated library instead, uploaded my first package to crates.io.

Got some people screaming at me that my Rust code sucked. Screamed back at them. After lots of screaming, I got some helpful PRs.

Eventually ended up building many services for work in Rust after all. With those services performing well under high load and having very few bugs, coworkers got interested. Started hiring Rust engineers, and educating interested PHP/JS devs.

Now I professionally write Rust code almost full-time.

Moral of the story:

Fuck books, use them for reference. Fuck Udemy (etc), unless you just want to 2x through it while pooping.

Learning is something you do by building a project, failing, building something else, falling again, building some more, sharing what you've made, fighting about what you've built with some entitled toxic nerds, abandoning half your projects and starting twelve new ones.

Reading code is better than reading documentation.

Listening to users of your library/product teaches you more than listening to keynote speakers at conferences.

Don't worry about failures, you don't need to deliver a working product for it to be a valuable experience.

Oh, and trying to teach OTHERS is an excellent method to discover gaps in your knowledge.

Just get your fucking hands dirty!

I started my internship at the end of the year..
Fuck my ass!!! This code I have to work with is a huge pile of shit.
The code base I need to work with is around 40k LOC. It is a mixture of C++, C, Java, Python, Bash and I think I saw some lonely js files around.

A list of awesome parts:
- Paths are hard coded.
- Redundant code everywhere
- No documentation or inline comments available

Most of the comments in the code are just old code that is not used anymore. But the cherry on the turd is the class that should provide all kind of useful functions in my daily routine. About ninety percent of the functions have the same description or nothing. Sometimes a function name says "readSomethingFromSomewhere" but instead it writes something to a file. It is really confusing and I need to check everything twice instead of rely on what the function name promises.
I have also learned why copy paste isn't that good. The brief descriptions of every method in a files are always the same.

getName() - Description: Fork child process
getIp() - Description: Fork child process
getIpv6() - Description: Fork child process.

Surprise: None of these functions forks a child process. :D

Another awesome feature is the thing that they store up to five different versions of libraries. Everyone with slight modifications but no hint which one you need to use. Sometimes it is the newest, sometimes the oldest which is running in production. Another case of try and error.
Oh and my dev machine is a potato with a power supply and a fan. I started with NetBeans and every time I compiled the code it sounds like the machine wants to lift off and leave for a better place. (At this point I switched to Emacs and everything runs smoothly now)

At first I thought that I'm just not that good at coding and understanding a big project from scratch but some colleagues have the same problem. The whole system is very inflexible and it is all about "std::cout"-debugging to check if your changes do what you want them to do.

Currently I'm just trying to fix this mess to make the life for the next student or employee easier. The first month was just frustrating as hell. I need to ask so many questions and most of the time the answer was "I don't know, haven't touched this code in years". Needless to say that my progress isn't that awesome but at least I get a nice payment for 20 hours of work a week.

Today was a manic-depressive kind of day. Spent the morning helping some developers with getting their code to run a stored procedure to drop old partitions, but it wasn't working on their end. It was a fairly simple proc. But working with partitions is a little like working with an array. I figured out that they were passing the wrong timestamp, and needed to add +1 to delete the right partition. Got that sorted out, and things were good. Lunch time.

After lunch I did some busy work, and then the PO comes up at about 2PM and says he's assigned some requests to me. The first was just attaching some scripts. Easy. The second, the user wants a couple of schemas exported ... at 6PM. I've been in the office since 6:45AM.

While I'm setting up some commands to run for the data export, a BA walks up and asks if I'm filling in for another DBA who is out for a few weeks. Yep. There's a change request that hasn't been assigned, and he normally does the work. I ask when it's due. Well, the pre-implementation was supposed to be done in the morning, but it wasn't, and we're in the implementation window ... half way through. I bring up the change task, and look at. Create new schema and users. That's all it says. The BA laughs. I tell I need more to go on. 10 minutes later he sends an email with the information. There's only two hours left in the window, and I can only use half of it, because the production guys have to their stuff, and we're in their window. Now I'm irritated, because I'm new to Oracle, and it's an unforgiving mistress. Fortunately, another DBA says he'll do it, so that we can get it done in time. But can't work it either, because Dev DBAs don't have access to QA, and the process required access for this task. Gets shelved until the access issue is resolved. It's now after 4:15PM. I'm going to in traffic with that 6PM deadline.

I manage to get home and to the computer by 5:45PM. Log in. Start VPN. Box pops on screen. Java needs to update. I chose skip update. Box pops up again. It won't let me log in until Java is current. Passed.

I finally get logged in, and it's 6:10PM. I'm late getting the job started. I pull up Putty and log into the first box, and paste my pre-prepared command in the command line and hit error. Command not found. I'm tired, so it's a moment to sink in. I don't have time for this.

I log into DBArtisan and pull up the first data base, use the wizard to set the job, and off it goes. Yay. Bring up the second database, and have enter the connect info. Host not found. Wut? Examine host name. Yep, it's correct. Try a different method. Host not found. Go back to Putty. Log in. Past string. Launch. Command not found. Now my brain is quitting on me. Why now? It's after 6:30PM. Fiddle with some settings, reset $Oracle home. Try again. Yay. It works. I'm done. It's after 7PM.

There is nothing like technology to snatch the euphoria of a success away from you. It's a love-hate thing, but I wouldn't trade it for anything else. I'm done. Good night.

So ok here it is, as asked in the comments.

Setting: customer (huge electronics chain) wants a huge migration from custom software to SAP erp, hybris commere for b2b and ... azure cloud
Timeframe: ~10 months….

My colleague and me had the glorious task to make the evaluation result of the B2B approval process (like you can only buy up till € 1000, then someone has to approve) available in the cart view, not just the end of the checkout. Well I though, easy, we have the results, just put them in the cart … hmm :-\
The whole thing is that the the storefront - called accelerator (although it should rather be called decelerator) is a 10-year old (looking) buggy interface, that promises to the customers, that it solves all their problems and just needs some minor customization. Fact is, it’s an abomination, which makes us spend 2 months in every project to „ripp it apart“ and fix/repair/rebuild major functionality (which changes every 6 months because of „updates“.

After a week of reading the scarce (aka non-existing) docs and decompiling and debugging hybris code, we found out (besides dozends of bugs) that this is not going to be easy. The domain model is fucked up - both CartModel and OrderModel extend AbstractOrderModel. Though we only need functionality that is in the AbstractOrderModel, the hybris guys decided (for an unknown reason) to use OrderModel in every single fucking method (about 30 nested calls ….). So what shall we do, we don’t have an order yet, only a cart. Fuck lets fake an order, push it through use the results and dismiss the order … good idea!? BAD IDEA (don’t ask …). So after a week or two we changed our strategy: create duplicate interface for nearly all (spring) services with changed method signatures that override the hybris beans and allow to use CartModels (which is possible, because within the super methods, they actually „cast" it to AbstractOrderModel *facepalm*).
After about 2 months (2 people full time) we have a working „prototype“. It works with the default-sample-accelerator data. Unfortunately the customer wanted to have it’s own dateset in the system (what a shock). Well you guess it … everything collapsed. The way the customer wanted to "have it working“ was just incompatible with the way hybris wants it (yeah yeah SAP, hybris is sooo customizable …). Well we basically had to rewrite everything again.
Just in case your wondering … the requirements were clear in the beginning (stick to the standard! [configuration/functinonality]). Well, then the customer found out that this is shit … and well …

So some months later, next big thing. I was appointed technical sublead (is that a word)/sub pm for the topics‚delivery service‘ (cart, delivery time calculation, u name it) and customerregistration - a reward for my great work with the b2b approval process???

Customer's office: 20+ people, mostly SAP related, a few c# guys, and drumrole .... the main (external) overall superhero ‚im the greates and ur shit‘ architect.
Aberage age 45+, me - the ‚hybris guy’ (he really just called me that all the time), age 32.
He powerpoints his „ tables" and other weird out of this world stuff on the wall, talks and talks. Everyone is in awe (or fear?). Everything he says is just bullshit and I see it in the eyes of the others. Finally the hybris guy interrups him, as he explains the overall architecture (which is just wrong) and points out how it should be (according to my docs which very more up to date. From now on he didn't just "not like" me anymore. (good first day)
I remember the looks of the other guys - they were releaved that someone pointed that out - saved the weeks of useless work ...

Instead of talking the customer's tongue he just spoke gibberish SAP … arg (common in SAP land as I had to learn the hard way).
Outcome of about (useless) 5 meetings later: we are going to blow out data from informatica to sap to azure to datahub to hybris ... hmpf needless to say its fucking super slow.
But who cares, I‘ll get my own rest endpoint that‘ll do all I need.

First try: error 500, 2. try: 20 seconds later, error message in html, content type json, a few days later the c# guy manages to deliver a kinda working still slow service, only the results are wrong, customer blames the hybris team, hmm we r just using their fucking results ...
The sap guys (customer service) just don't seem to be able to activate/configure the OOTB odata service, so I was told)
Several email rounds, meetings later, about 2 months, still no working hybris integration (all my emails with detailed checklists for every participent and deadlines were unanswered/ignored or answered with unrelated stuff). Customer pissed at us (god knows why, I tried, I really did!). So I decide to fly up there to handle it all by myself

I really hate PHP frameworks.

I also often write my own frameworks but propriety. I have two decades experience doing without frameworks, writing frameworks and using frameworks.

Virtually every PHP framework I've ever used has causes more headaches than if I had simply written the code.

Let me give you an example. I want a tinyint in my database.

> Unknown column type "tinyint" requested.

Oh, doctrine doesn't support it and wont fix. Doctrine is a library that takes a perfectly good feature rich powerful enough database system and nerfs it to the capabilities of mysql 1.0.0 for portability and because the devs don't actually have the time to create a full ORM library. Sadly it's also the defacto for certain filthy disgusting frameworks whose name I shan't speak.

So I add my own type class. Annoying but what can you do.

I have to try to use it and to do so I have to register it in two places like this (pseudo)...

Types::add(Tinyint::class);
Doctrine::add(Tinyint::class);

Seems simply enough so I run it and see...

> Type tinyint already exists.

So I assume it's doing some magic loading it based on the directory and commend out the Type::add line to see.

> Type to be overwritten tinyint does not exist.

Are you fucking kidding me?

At this point I figure out it must be running twice. It's booting twice. Do I get a stack trace by default from a CLI command? Of course not because who would ever need that?

I take a quick look at parent::boot(). HttpKernel is the standard for Cli Commands?

I notice it has state, uses a protected booted property but I'm curious why it tries to boot so many times. I assume it's user error.

After some fiddling around I get a stack trace but only one boot. How is it possible?

It's not user error, the program flow of the framework is just sub par and it just calls boot all over the place.

I use the state variable and I have to do it in a weird way...

> $booted = $this->booted;parent::boot();if (!$booted) {doStuffOnceThatDependsOnParentBootage();}

A bit awkward but not life and death. I could probably just return but believe or not the parent is doing some crap if already booted. A common ugly practice but one that works is to usually call doSomething and have something only work around the state.

The thing is, doctrine does use TINYINT for bool and it gets all super confused now running commands like updates. It keeps trying to push changes when nothing changed. I'm building my own schema differential system for another project and it doesn't have these problems out of the box. It's not clever enough to handle ambiguous reverse mappings when single types are defined and it should be possible to match the right one or heck both are fine in this case. I'd expect ambiguity to be a problem with reverse engineer, not compare schema to an exact schema.

This is numpty country. Changing TINYINT UNSIGNED to TINYINT UNSIGNED. IT can't even compare two before and after strings.

There's a few other boots I could use but who cares. The internet seems to want to use that boot function. There's also init stages missing. Believe it or not there's a shutdown and reboot for the kernel. It might not be obvious but the Type::add line wants to go not in the boot method but in the top level scope along with the class definition. The top level scope is run only once.

I think people using OOP frameworks forget that there's a scope outside of the object in PHP. It's not ideal but does the trick given the functionality is confined to static only. The register command appears to have it's own check and noop or simply overwrite if the command is issued twice making things more confusing as it was working with register type before to merely alias a type to an existing type so that it could detect it from SQL when reverse engineering.

I start to wonder if I should just use columnDefinition.

It's this. Constantly on a daily basis using these pretentious stuck up frameworks and libraries.

It's not just the palava which in this case is relatively mild compared to some of the headaches that arise. It's that if you use a framework you expect basic things out of the box like oh I don't know support for the byte/char/tinyint/int8 type and a differential command that's able to compare two strings to see if they're different.

Some people might say you're using it wrong. There is such a thing as a learning curve and this one goes down, learning all the things it can't do. It's cripplesauce.

I went down a rabbit hole of code changes to try and delete a stupid for loop with a break in it.

It was super stupid and I gave up and submitted to the fact that some battles are not worth the time and stress.

OK... But seriously, It was returning multiple entities from the database, but we only always want the first one. My logic is that we should just go in there and fix the LINQ so we are explicitly getting one entity out.

But fuck that logic. No I'll have to change fucking everything that's tied to that method and expects a list from it. Every fucking thing. That includes error handling, parsing, for loops..... Nevermind...

You can have your foreach and your break. I'm taking mine, now.

I wasn't happy with one of our UI views for editing a database query that consisted of about 50 fields ("editing" being the operative term here, not just viewing. It had to be two-way). Everything was hardcoded and defined manually, with each block of ~10 lines being repeated and mostly identical apart from the occasional double inline field and name of the variable. It had "just ended up that way" over time due to the variable names in the UI being different than the names of the variables that came from the API.

I decided to overhaul it all where I defined the different input components and which fields should be included, then made a function which would generate the page based on these definitions. It was about 500 lines of modularized functions and classes where the class for the actual view was about 50 lines- compared to the 1400+ lines of the previous version.

But, it didn't work. It should, but it "just didn't". There was no error. All I got was a blank, solid white page. I could make a drastic change or try something completely different and I would get the same error, same blank page. API fetch succeeded, value assignments succeeded, the object exists, but if you iterated it it was... empty.

I started getting really discouraged that I had made it too abstract. Maybe I actually made it more complex and unreadable than before. Maybe just hardcoding it all was the better solution after all. Maybe I had gone against KISS and overdesigned it.

I was up pretty late and everyone had gone home. When the last guy left there was that mood where "yeah if I can't make this work we'll just use the current version...".

Turns out I had tried iterating over a property of the set of fields to render, rather than the entire collection. In the old method the variables were a member of an object, but now they were its own object, a change I had made to isolate the set of values which were to be viewed/edited and make them easier to pass back and forth. This member existed since I hadn't cleaned it out yet, but it was empty.

I had been banging my head against this for a whole day and I was ready to admit I had made a mistake and wasted my time before discarding it all, but then I backspaced this one property and the interface went from empty to rendering perfectly and with all functionality intact. I swear god rays were coming out of my screen.

Fustration? Every time, I'm not good at design, from choosing colors to aligment.
I always end with the try and error method to get something works.

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

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

I pass the day writing a script to encapsulate the migration of the old csproj to the new format. But, when the open source app returns an error of migrating the script continue. I check the return code and when it's an error, it's return 0.

After many tries, I return to my house and start looking at the open source code for understand what's happening and try to correct it.

OMFG, I cannot change the code to return an `int` instead of void. The method is in the public area of the code.

I very happy that this app, it's open source, so I can do my own version for my need.

Funcking symfony 4. THey give error:

You can not use the "render" method if the Templating Component or the Twig Bundle are not available. Try running "composer require symfony/twig-bundle".

I have run this command to required twig bundle, it installed succesfully and still there is the error. Wtf. Cannot use fucking stupid simple twig.

How can i fix this?
