"Working with legacy code that hasn't been touched in 2 years is fun!!" said no one ever.

Fucking hell, the devs before write a query that pulls 30ish column for a report. When I break it down MANUALLY, since it’s a spaghetti on top of another spaghetti, you only need 6. Fuck you, did you dropped your head when you was a kid? Fuck sake, and every query is written in stored procedure even though you’re using an entity libraries

It was 1999. I was just starting my first real job as a programmer for a major insurance company. We were working on code that would screen scrape legacy mainframe data output and convert it to a web-based UI. REALLY stupid project approach I had no input on. I happened to find a programmer in Germany who had released his code in the public domain that would help with making a certain conversion task easier. I downloaded his code and put it to work.

During a code review, a programmer who was probably about 60 asked me where I got the code and what it was doing. I didn't even get to the part about what it was doing because he made fun of me so badly, in a fake German accent in front of a room full of non-programmers, for using code that today is no big deal due to the prevalence of open source. I just clammed up in humiliation because he got everyone laughing at me. His philosophy was if we didn't buy it or write it ourselves, we had no business using it.

I guess I was just ahead of my time?

Just read an article that really grinds my gears. Its about coding in other languages. Not programming languages, but literally other languages.

Btw I learned to code in Spanish and I'm not against coding in programming languages using variable names in other languages.

That's fine.

What pissed me off was that the author claimed that we should be able to code Fucking JavaScript in SWAHILI or other languages available. What kind of PC bullshit is that!

Coding is barely fucking readable and now we have to make standards for Multilanguage support. Just learn the less than 60 reserved words you lazy fuck and code with them! I leaned to code with shitty tutorials in Spanish and theres no 1000x resources out there and this author claims you can't code unless you know english.

Granted. It's easier but wtf not just learn it. When I coded in Java in Spanish, I didn't know wtf a Class was or ags meant. So what. I memorized that shit. How? By coding!

Why bring this PC shit to programming? The author thinks there are few programmers bc we don't support fucking SWAHILI in JavaScript. Fuck no!

Now if you want to support this initiative. Think of this,

...legacy code

...in 32+ languages.

Have fun debugging this thing.

How do you get over the bad times? I keep having to work with shitty legacy systems that were written in perl and flash in the 90s, but my boss keeps telling me "No" on redoing some of the bigger stuff even though it is really needed. I mean, that is your goal here, right? Rebuilding this POS? FFS you still stored passwords in plain text twoo weeks ago! But no, you's rather dig around in Perl than upset some random user because his fucking interface looks different.

But then I also have to work with another system that I could redo in Cake/Laravel in two weeks (it's literally getting and writing data to one table, so two views and user auth), and the previous dev just... made a huge mess. I mean, why would you need to post data asynchronously when it's this one stupid form ? Just do a regular form submit? And the system is really not suitable for extending, because everything is in the database, EVERYTHING! Like, html form inputs? So to add a simple input to the template I have to create a new input type in the types table and then add that to the form structure table? Only to have the input checked by fucking regex? REGEX! Why? Seriously, this is not some high end CMS that needs this level of code reusability No. This is a simple fucking form.

And I can't get it to work. No documentation of course. No comments, either. All of this makes me feel like I'm just the shittiest dev ever. I feel dumb, and useless. Haven't turned on my private PC in weeks because I see no reason to work on any of my own stuff.

I used to have a job, working with Magento and Wordpress. And yeah, it was horrible, it was chaos, but it was fun and I was great at it. I bent that motherfucking system to fit my needs. People respected my opinion, they were convinced I could program this and that, and I proved them right. Did I make mistakes? Hell yeah. Did I give up? Fuck no!

But now, I just feel like I can't even write a simple fucking form any more. I'm just so close to giving up on development as a whole, even though I love it so much.

So, it's been a while since I've been working on my current project and I've never had the "luck" to touch the legacy project wrote in PHP, until this week when I got my first issue.

And damn, this goddamn issue. It was a bug, a very strange bug, that only happens in production and that nobody has any idea what was happening, so yeah, I didn't have anyone to ask and I got less time than usual ( because Thanksgiving ).

And thus, I have no starting point, no previous knowledge on PHP and less time! I expected a very fun week 😀 and it was beyond my expectations.

First I tried to understand what might be causing the issue, but there wasn't any real clue to star with, so no choice, time to read the flow on the code and see what are they're doing and using ( 1k line files, yay, legacy ). Luckily I got some clues, we're using a cookie and a php session variable for the session, ok, let's star with the session variable. Where it's that been initialize ? Well, spoiler alert, I shouldn't start with that, because my search end up in the login method of the API that set a that variable and for some reason in the front end app it was always false and that lead me to think that some of the new backend functions were failing, but after checking the logs I got no luck.

Ok, maybe the cookie it's the issue, I should try open the previous website on the brow...redirect to new project login, What? Why ? I ask around and it's a new feature push on Monday, ok I got Chrome Dev tools I can see which value of the cookie it's been set and THERE IT WAS it has a wrong domain! After 2 days ( I resume a lot of my pain ) I got what I've been looking for, so now I should be able to fix the bug. Then where is the cookie initialized ? In the first file the server hits whenever you tried to enter any page of the app, ok, I found the method, but it's using a function that process the domain and sets it correctly? wtf ? Then how in heaven do I get the incorrect domain ? Hello? Ok, relax, you still have one more day to fix this, let's take it easy.

Then, at the end of the Wednesday, nope I still have no clue how this is happening. I talked with the Devops guy and he explain me how this redirection happens and with what it depends on, I followed the PHP code through and nothing, everything should works fine, sigh. Ok I still have 2 days, because I'm not from US and I'm not in US, so I still have time, but the Sprint is messed up already, so whatever I'm gonna had done this bug anyhow.

Thursday ! I got sick, yay, what else could happen this week. Somehow I managed to work a little and star thinking in what external issue could affect the processing, maybe the redirection was bringing a wrong direction, let's talk with the Devops guy again, and he answer me that the redirection it was being made by PHP code, IN A FILE THAT DOESN'T EXIST IN THE REPOSITORY, amazing, it's just amazing. Then he explained me why this file might be missing and how it's the deployment of this app ( btw the Devops guy it's really cool and I will invite him a beer ) . After that I checked the file and I see a random session_star in the first line of the code, without any configuration, eureka ! There was the cause and I only need to ask someone If that line it's necessary anymore, but oh they're on holiday, damn, well I'll wait till Monday to ask them. But once and for all that bug was done for ! 🎉

What do I learn ? PHP and that I don't want any more tickets of PHP 😆.

February will be the first full year at this company as full time employee.

I've updated so many legacy projects, optimized a lot of workflows as well as built new tools to improve efficiency and remove unnecessarily duplicate projects (sometimes literally only 3 variables were different between multiple projects)

My one co-worker taught himself enough code to do the job but doesn't think like a programmer though he is asking me for help and advice to improve what he does since ive proven i know a little. my other direct co-worker I'm practically teaching a Programming 100 course to them

My direct manager at one point said he was so happy he took a chance on me even though I didn't interview well

I like my job, I find it so much better than my last job which was horribly toxic, and more fun than my first 'real' job as a night shift help desk for basically a warehouse environment.

But I feel under paid sometimes for how much i do and all ive improved in my first year, I have my first yearly review coming up. I'm hoping to get a decent raise for all ive done and I want to somehow go over everything with the HR person to justify it. But I have no idea how to talk about my dev work to them in a way a non technical person could understand. I'm also not sure how the review process will work. Like will my manager be there. Or is it just me and HR, is there a paper I'll be sent to fill before hand,

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!

After almost 3 years of professional experience I’d like to specialize more in something but I struggle to because I enjoy almost every aspect of IT: I find front-end really fun, I find very rewarding to build good user experiences and I’m excited for what WASM may bring on the table but I even like to work on the back end on both: legacy monoliths and modern micro services, I love to refactor clunky programs full of “cargo cult” code and redundancies put by people who doesn’t understand the framework they’re using and to make them shine. I’m even good at UNIX/Linux scripting and with Docker (often colleagues asks me advice on these topics) so I’m really tempted to upgrade my knowledge by learning K9S and reading the 1000+ pages of Unix Power Tools to get into operations/DevOps especially considering which the field is the least likely to be overrun by cheap developers coming from a 3 months boot camp.
On top of that I’ve got even into more theoretical topics: I’m following a course on algorithms and data structures in C and in future I want to learn the basics of AI for a personal project but these things aren’t much about employment but personal culture.
Have you got any advice for this disoriented young man?
