I realize I've ranted about this before, but...

Fuck APIs.

First the fact that external services can throw back 500 errors or timeouts when their maintainer did a drunk deploy (but you properly handled that using caching, workers, retry handlers, etc, right? RIGHT?)...

Then the fact that they all speak a variety of languages and dialects (Oh fuck why does that endpoint return a JSON object with int keys instead of a simple array... wait the params are separated with pipe characters? And the other endpoint uses SOAP? Fuck I need to write another wrapper class around the client...)

But the worst thing: It makes developers live in this happy imaginary universe where "malicious" is not a word.

"I found this cloud service which checks our code style" — hmm ok, they seem trustworthy. Hope they don't sell our code, but whatever.

"And look at this thing, it automatically makes database backups, just have to connect to it to DigitalOcean" — uhhh wait...

"And I just built this API client which sends these forms to be OCR processed" — Fuck... stop it... there are bank accounts numbers on those forms... Where's that API even located? What company?

* read their privacy policy *

"We can not guarantee the safety of your personal data, use at your own risk [...] we are located in Russia".

I fucking hate these millennial devs who literally fail to get their head out of the cloud.

Somehow they think it's easier to write all these NodeJS handlers and layers around some API, which probably just calls ImageMagick + Tesseract on the other side.

If I wasn't so fucking exhausted, I'd chop of their heads... but they're like hydra, you seal one privacy breach and another is waiting to be merged, these kids just keep spewing their crap into easy packages, they keep deploying shitty heroku apps... ugh.

My code review nightmare part 3

Performed a review on/against a workplace 'nemesis'. I didn't follow the department standards document (cause I could care less about spacing, sorted usings, etc) and identified over 80 bugs, logic errors, n+1 patterns, memory leaks (yes, even in .net devs can cause em'), and general bad behavior (ex.'eating' exceptions that should be handled or at least logged)

Because 'Jeff' was considered a golden child (that's another long TL;DR), his boss and others took a major offense and demanded I justify my review, item by item.

About 2 hours into the meeting, our department mgr realized embarrassing Jeff any further wasn't doing anyone any good and decided to take matters into his own hands. Thinking 'well, its about time he did his job', I go back to my desk. About an hour later..
Mgr: "I need you in the conference room, RIGHT NOW!"
<oh crap>
Mgr: "I spoke to Jeff and I think I know what the problem is. Did you ever train him on any of the problems you identified in the review?"
Me: "Um, no. Why would I?"
Mgr: "Ha!..I was right. So lets agree the problems are partially your fault, OK?"
Me: "Finding the bugs in his code is somehow my fault?"
Mgr: "Yes! For example, the n+1 problem in using the WCF service, you never trained him on how to use the service. You wrote the service, correct?"
Me: "Yes, but it's not my job to teach him how to write C#. I documented the process and have examples in the document to avoid n+1. All he had to do was copy/paste."
Mgr: "But you never sat with Jeff and talked to him like a human being? You sit over there in your silo and are oblivious to the problems you cause. This ends today!"
Me: "What the...I have no idea what you are talking about. What in the world did Jeff tell you?"
Mgr: "He told me enough and I'm putting an end to it. I want a compressive training class developed on how to use your service. I'll give you a month to get your act together and properly train these developers."

3 days later, I submit the power-point presentation and accompanying docs. It was only one WCF with a handful of methods. Mgr approved the training, etc..etc. execute the 'training', and Jeff submits a code review a couple of weeks later. From over 80 issues to around 50. The poop hits the fan again.

Mgr: "What's your problem? When are you going to take your responsibility seriously?"
Me: "Its pretty clear I don't have the problem. All the review items were also verified by other devs. Its not me trying to be an asshole."
Mgr: "Enough with the excuses. If you think you can do a better job *you* make the code changes and submit them for Jeff for review. No More Excuses!"

Couple of days later, I make the changes, submit them for review, and Jeff really couldn't say too much other than "I don't see this as an improvement"

TL;DR, I had been tracking the errors generated by the site due to the bugs prior to my changes. After deployment, # of errors went from thousands per hour to maybe hundreds per day (that's another story) and the site saw significant performance increases, fewer customer complaints, etc..etc.

At a company event, the department VP hands out special recognition awards:

VP: "This award is especially well earned. Not only does this individual exemplify the company's focus on teamwork, he also went above and beyond the call of duty to serve our customers. Jeff, come on up and get this well deserved award."

Dynamically typed languages are barbaric to me.

It's pretty much universally understood that programmers program with types in mind (if you have a method that takes a name, it's a string. You don't want a name that's an integer).

Even it you don't like the verbosity of type annotations, that's fine. It adds maybe seconds of time to type, which is neglible in my opinion, but it's a discussion to be had.

If that's the case, use Crystal. It's statically typed, and no type annotations are required (it looks nearly identical to Ruby).

So many errors are fixed by static typing and compilers. I know a person who migrated most of the Python std library to Haskell and found typing errors in it. *In their standard library*. If the developers of Python can't be trusted to avoid simple typing errors with all their unit tests, how can anyone?

Plus, even if unit testing universally guarded against typing errors, why would you prefer that? It takes far less time to add a type annotation (and even less time to write nothing in Crystal), and you get the benefit of knowing types at compile time.

I've had some super weird type experiences in Ruby. You can mock out the return of the type check to be what you want. I've been unit testing in Ruby before, tried mocking a method on a type, didn't work as I expected. Checked the type, it lines up.

Turns out, nested away in some obscure place was a factory that was generating types and masking them as different types because we figured "since it responds to all the same methods, it's practically the same type right?", but not in the unit test. Took 45 minutes on my time when it could've taken ~0 seconds in a statically typed language.

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.

I'm exhausted.
After one and a half year after my last rant, I'm here again. I left the previous job as web developer after almost 12y. At the time I found 3 new jobs as developer; I chose the one with the largest company, the premises were really good. My 3 interviews were excellent. But what I found next was almost a nightmare.
I was literally "confined" for the first 2 months, no internet connection, no email address, very little communication with colleagues. My near colleague was sharing the code were I would work via a usb key. All this for "safety" purposes, because "here you start this way".
For me it was not so bad, I could take my time to study my work and do it (without Stack Overflow and only by reference guides, when needed - I felt proud in an old way). But the next months were really tough: no help to understand what I missed about the work I was doing (consider that I was working on a large database, previously used by an old ERP, on which other developers - prior me - wrote a lot of code, to make the company continue use all the data after the expiration of the ERP licences - speaking about a year 2000's Java application).
Now I find myself struggling, because the main project on which I was working has been set aside (apparently for some budget decisions); my work team constantly make me do some manteinance on the old code, but the main tasks are done by the old mate, "because deadlines are always pressing and there would not be enough time to explain you anything". I'm not growing.
I'm really becoming reluctant to write code, and whenever I do it, I constantly feel under pressure, and this makes me nervous and inclined to make errors.
Don't take me wrong, I was/am good at my work, but it's like I'm loosing that sparkle I had till a few years ago.
When I'm at home I try to study or write code, just to keep training my mind, but I'm really struggling and I'm worried about losing my brain for doing this job. I constantly forget things and lose focus.
Never felt this way. I am thinking about the chance to switch again and search for another company.

I AM TIRED

warning: this rant is going to be full of negativity , CAPS, and cursing.

People always think and they always write that programming is an analytical profession. IF YOU CANNOT THINK IN AN ANALYTICAL WAY THIS JOB IS NOT FOR YOU! But the reality could not be farther from the truth.

A LOT of people in this field whether they're technical people or otherwise, just lack any kind of reasoning or "ANALYTICAL" thinking skills. If anything, a lot of of them are delusional and/or they just care about looking COOL. "Because programming is like getting paid to solve puzzles" *insert stupid retarded laugh here*.

A lot of devs out there just read a book or two and read a Medium article by another wannabe, now think they're hot shit. They know what they're doing. They're the gods of "clean" and "modular" design and all companies should be in AWE of their skills paralleled only by those of deities!

Everyone out there and their Neanderthal ancestor from start-up founders to developers think they're the next Google/Amazon/Facebook/*insert fancy shitty tech company*.

Founder? THEY WANT TO MOVE FAST AND GET TO MARKET FAST WITH STUPID DEADLINES! even if it's not necessary. Why? BECAUSE YOU INFERIOR DEVELOPER HAVE NOT READ THE STUPID HOT PILE OF GARBAGE I READ ONLINE BY THE POEPLE I BLINDLY COPY! "IF YOU'RE NOT EMBARRASSED BY THE FIRST VERSION OF YOU APP, YOU DID SOMETHING WRONG" - someone at Amazon.

Well you delusional brainless piece of stupidity, YOU ARE NOT AMAZON. THE FIRST VERSION THAT THIS AMAZON FOUNDER IS EMBARRASSED ABOUT IS WHAT YOU JERK OFF TO AT NIGHT! IT IS WHAT YOU DREAM ABOUT HAVING!

And oh let's not forget the tech stacks that make absolutely no fucking sense and are just a pile of glue and abstraction levels on top of abstraction levels that are being used everywhere. Why? BECAUSE GOOGLE DOES IT THAT WAY DUH!! And when Google (or any other fancy shit company) changes it, the old shitty tech stack that by some miracle you got to work and everyone is writing in, is now all of a sudden OBSOLETE! IT IS OLD. NO ONE IS WRITING SHIT IN THAT ANYMORE!

And oh my god do I get a PTSD every time I hear a stupid fucker saying shit like "clean architecture" "clean shit" "best practice". Because I have yet to see someone whose sentences HAVE TO HAVE one of these words in them, that actually writes anything decent. They say this shit because of some garbage article they read online and in reality when you look at their code it is hot heap of horseshit after eating something rancid. NOTHING IS CLEAN ABOUT IT. NOTHING IS DONE RIGHT. AND OH GOD IF THAT PERSON WAS YOUR TECH MANAGER AND YOU HAVE TO LISTEN TO THEM RUNNING THEIR SHITHOLE ABOUT HOW YOUR SIMPLE CODE IS "NOT CLEAN". And when you think that there might be a valid reason to why they're doing things that way, you get an answer of someone in an interview who's been asked about something they don't know, but they're trying to BS their way to sounding smart and knowledgable. 0 logic 0 reason 0 brain.

Let me give you a couple of examples from my unfortunate encounters in the land of the delusional.

I was working at this start up which is fairly successful and there was this guy responsible for developing the front-end of their website using ReactJS and they're using Redux (WHOSE SOLE PURPOSE IS TO ELIMINATE PASSING ATTRIBUTES FOR THE PURPOSE OF PASSING THEM DOWN THE COMPONENT HIERARCHY AGIAN). This guy kept ranting about their quality and their shit every single time we had a conversation about the code while I was getting to know everything. Also keep in mind he was the one who decided to use Redux. Low and behold there was this component which has THIRTY MOTHERFUCKING SEVEN PROPERTIES WHOSE SOLE PURPOSE IS BE PASSED DOWN AGAIN LIKE 3 TO 4 TIMES!.

This stupid shit kept telling me to write code in a "functional" style. AND ALL HE KNOWS ABOUT FUNCTIONAL PROGRAMMING IS USING MAP, FILTER, REDUCE! And says shit like "WE DONT NEED UNIT TESTS BECAUSE FUNCTIONAL PROGRAMMING HAS NO ERRORS!" Later on I found that he read a book about functional programming in JS and now he fucking thinks he knows what functional programming is! Oh I forgot to mention that the body of his "maps" is like 70 fucking lines of code!

Another fin-tech company I worked at had a quote from Machiavelli's The Prince on EACH FUCKING DESK:

"There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things."

MOTHERFUCKER! NEW ORDER OF THINGS? THERE 10 OTHER COMPANIES DOING THE SAME SHIT ALREADY!

And the one that got on my nerves as a space lover. Is a quote from Kennedy's speech about going to the moon in the 60s "We choose to go to the moon and do the hard things ..."

YOU FUCKING DELUSIONAL CUNT! YOU THINK BUILDING YOUR SHITTY COPY PASTED START UP IS COMPARABLE TO GOING TO THE MOON IN THE 60S?

I am just tired of all those fuckers.

Conversation yesterday (senior dev and the mgr)..

SeniorDev: "Yea, I told Ken when using the service, pass the JSON string and serialize to their object. JSON eliminates the data contract mismatch errors they keep running into."
Mgr: "That sounds really familiar. Didn't we do this before?"
SeniorDev: "Hmmm...no. I doubt anyone has done this before."
Me: "Yea, our business tier processor handled transactions via XML. It allowed the client and server to process business objects regardless of platform. Partners using Perl,
clients using Delphi, website using .aspx, and our SQLServer broker even used it."
Mgr: "Oh yea...why did we stop using it?"
Me: "WCF. Remember, the new dev manager at the time and his team broke up the business processor into individual WCF services."
Mgr: "Boy, that was a crap fest. We're still fighting bugs from the mobile devices. Can't wait until we migrate everything to REST."
SeniorDev: "Yea, that was such a -bleep-ing joke."
Me: "You were on Jake's team at the time. You were the primary developer in the re-write process saying passing strings around wasn't the way true object-oriented developers write code.
So it's OK now because the string is in JSON format or because using a JSON string your idea?"

SeniorDev turns around in his desk and puts his headphones back on.

That's right you lying SOB...I remember exactly the level of personal attacks you spewed on me and other developers behind our backs for using XML as the message format.

Keep your fat ass in your seat and shut the hell up.

In my previous company we developed a CRM web app for the company to use internally and it was in my humble opinion really easy to make sense of, but for some freaking we kept getting calls whenever someone got an error, and our default response was always to send us an email, then we will get back to you, as it was mostly stupid things they called about, for example, a customer might have to be status terminated, before you can click button A, button A would then be disabled and employees would call asking why. Apparently, people got annoyed by our response and went to the management, to get some guidelines as to when they could call the "development apartment" for help, so the management sends out some guidelines as to when they could call, write or whatever... The following was done without consulting us in any way ANY WAY AT ALL!... Because we all know management knows fucking best, and why bother asking the people that sit with it every day, and the way it was done was by saying:

If the background color on your error is red, it means the error is fatal and you can call the developers immediately, if its orange send an email and they will answer within 48 hours LIKE WTF... Seriously???. That was basically it, and honestly we had just been using colors, without much thought to it ofc red, was an error etc. But they we're not "OMG EVERYTHING IS BREAKING" alert, so we decided to use a couple of hours refactoring the color of the flash errors, and after that, we did not have many red alerts(None, yes none what so ever) We changed all the red ones to orange, and introduced some new colors. That worked for some time around 6 months or so, but then people obviously started calling again like, why even bother... So we created a simple service desk, blocked all incoming calls to our phones that were from regular employees, heard a lot of complaints about this from the employees, management was mad, we had so many meetings with those top paid management fuckers that know everything (way better than you and me), about how to handle this. As it took way too much of our time, that people couldn't bother trying simple things, or make some sense as to why a button is disabled etc. We ended up "winning", was allowed to block calls for some time, till the employees had learned to use a freaking simple service desk, it's not fucking rocket science Okay, stop being a pain in the ass... And it actually fucking worked! Most relaxing time after people got a hang of using the service desk instead of calling life was good after that... <3

2 hour meeting to brainstorm ideas to improve our system health monitoring (logging, alerting, monitoring, and metrics)

Never got past the alerting part. Piss poor excuses for human being managers kept 'blaming' our logging infrastructure for allowing them to log exceptions as 'Warnings', purposely by-passing the alerting system.

Then the d-head tried to 'educate' everyone the difference between error and exception …frack-wad…the difference isn't philosophical…shut up.

The B manager kept referring to our old logging system (like we stopped using it 5 years ago) and if it were written correctly, the legacy code would be easier to migrate. Fracking lying B….shut the frack up.

The fracking idiots then wanted to add direct-bypass of the alerting system (I purposely made the code to bypass alerting painful to write)

Mgr1: "The only way this will work is if you, by default, allow errors to bypass the alerting system. When all of our code is migrated, we'll change a config or something to enable alerting. That shouldn't be too hard."
Me: "Not going to happen. I made by-passing the alert system painful on purpose. If I make it easy, you'll never go back and change code."
Mgr2: "Oh, yes we will. Just mark that method as obsolete. That way, it will force us to fix the code."
Me: "The by-pass method is already obsolete and the teams are already ignoring the build warnings."
Mgr1: "No, that is not correct. We have a process to fix all build warnings related to obsolete methods."
Mgr2: "Yes. It won't be like the old system. We just never had time to go back and fix that code."
Me: "The method has been obsolete for almost a year. If your teams haven't fixed their code by now, it's not going to be fixed."
Mgr1: "You're expecting everything to be changed in one day. Our code base is way too big and there are too many changes to make. All we are asking for is a simple change that will give us the time we need to make the system better. We all want to make the system better…right?"
Me: "We made the changes to the core system over two years ago, and we had this same conversation, remember? If your team hasn't made any changes by now, they aren't going to. The only way they will change code to the new standard is if we make the old way painful. Sorry, that's the truth."
Mgr2: "Why did we make changes to the logging system? Why weren't any of us involved? If there were going to be all these changes, our team should have been part of the process."
Me: "You were and declined every meeting and every attempt to include your area. Considering the massive amount of infrastructure changes there was zero code changes required by your team. The new system simply worked. You can't take advantage of the new features which is why we're here today. I'm here to offer my help in any way I can with the transition."
Mgr1: "The new logging doesn't support logging of the different web page areas. Until you can make that change, we can't begin changing our code."
Me: "Logging properties is just a name+value pair dictionary. All you need to do is standardize on a name and how you add it to the collection."
Mgr2: "So, it's not a standard field? How difficult would it be to change the core assembly? This has to be standard across all our areas and shouldn't be up to the developers to type in anything they want."
- Frack wads smile and nod to each other like fracking chickens in a feeding frenzy
Me: "It can, but what will you call this property? What controls its value?"
- The look I got from both the d-bags I could tell a blood vessel popped.
Mgr1: "Oh…um….I don't know…Area? Yea … Area."
Mgr2: "Um…that's not specific enough. How about Page?"
Mgr1: "Well, pages can cross different areas, and areas cross different pages…what do you think?"
Me: "Don't know, don't care. It's up to you. I just need a name."
Mgr2: "Modules! Our MVC framework is broken up in Modules."
DevMgr: "We already have a field for Module. It's how we're segmenting the different business processes"
Mgr1: "Doesn't matter, we'll come up with a name later. Until then, we won't make any changes until there is a name."
DevMgr: "So what did we accomplish?"
Me: "That we need to review the web's logging and alerting process and make sure we're capturing errors being hidden as warnings."
Mgr1: "Nooo….we didn't accomplish anything. This meeting had no agenda and no purpose. We should have been included in the logging process changes from day one."
Mgr2: "I agree, I'm not sure why we're here"
Me: "This was a brainstorming meeting as listed in the agenda. We've accomplished 2 of the 4 items. I think we've established your commitment to making the system better. Thank you all for coming."

- Mgr1 and 2 left without looking at me or saying a word.

I think maybe I am doing something wrong.

I have this node.js application I am building with typescript and I wrote tests in mocha. Now I need to make some changes which break quite a few tests.

When I run mocha on the command line the errors whizz past. When I worked in java and .net (with junit and nunit) you could just click a test in the ide to run it. So you could 'fix' one test at a time. Also you could just double click on a fail and it would jump you to the code for that test or the exception that failed.

I found this extension for visual studio code that adds a sidebar to visual studio code. It looked good but now I spent the last hour trying to get it to run typescript tests - looks like it doesn't support the compilers argument.

Surely other developers must do this sort of stuff. I am not using an obscure technology stack right? Do you write automated tests for your codebase? What tools do you use? Should I switch ide? switch testing frameworks?

Okay. Here's the ONLY two scenarios where automated testing is justified:
- An outsourcing company who is given the task of bug elimination in legacy code with a really short timeframe. Then yes, writing tests is like waging war on bugs, securing more and more land inch after inch.
- A company located in an area where hiring ten junior developers is cheaper than hiring one principal developer. Then yes, the business advantage is very real.

That's it. That's the only two scenarios where automated testing is justified. Other such scenarios doesn't exist.

Why? Because any robust testing system (not just "adding some tests here and there") is a _declarative_ one. On top of already being declarative (opposed to the imperative environment where the actual code exists), if you go further and implement TDD, your tests suddenly begins to describe your domain area, turning into a declarative DSL.

Such transformations are inevitable. You can't catch bugs in the first place if your tests are ignorant of entities your code is working with.

That being said, any TDD-driven project consists of two things:
- Imperative code that implements business logic
- Declarative DSL made of automated tests that also describes the same business logic

Can't you see that this system is _wet_? The tests set alone in a TDD-driven project are enough to trivially derive the actual, complete code from it.

It's almost like it's easier to just write in a declarative language in the first place, in the same way tests are written in TDD project, and scrap the imperative part altogether.

In imperative languages, absence of errors can be mathematically guaranteed. In imperative languages, the best performance (e.g. the lowest algorithmic complexity) can also be mathematically guaranteed. There is a perfectly real point after which Haskell rips C apart in terms of performance, and that point happens earlier on than you think.

If you transitioned from a junior who doesn't get why tests are needed to a competent engineer who sees value in TDD, that's amazing. But like with any professional development, it's better to remember that it's always possible to go further. After the two milestones I described, the third exists — the complete shift into the declarative world.

For a human brain, it's natural to blindly and aggressively reject whatever information leads to the need of exiting the comfort zone. Hence the usual shitstorm that happens every time I say something about automated testing. I understand you, and more than that, I forgive you.

The only advice I would allow myself to give you is just for fun, on a weekend, open a tutorial to a language you never tried before, and spend 20 minutes messing around with it. Maybe you'll laugh at me, but that's the exact way I got from earning $200 to earning $3500 back when I was hired as a CTO for the first time.

Good luck!
