I'm drunk and I'll probably regret this, but here's a drunken rank of things I've learned as an engineer for the past 10 years.

The best way I've advanced my career is by changing companies.

Technology stacks don't really matter because there are like 15 basic patterns of software engineering in my field that apply. I work in data so it's not going to be the same as webdev or embedded. But all fields have about 10-20 core principles and the tech stack is just trying to make those things easier, so don't fret overit.

There's a reason why people recommend job hunting. If I'm unsatisfied at a job, it's probably time to move on.

I've made some good, lifelong friends at companies I've worked with. I don't need to make that a requirement of every place I work. I've been perfectly happy working at places where I didn't form friendships with my coworkers and I've been unhappy at places where I made some great friends.

I've learned to be honest with my manager. Not too honest, but honest enough where I can be authentic at work. What's the worse that can happen? He fire me? I'll just pick up a new job in 2 weeks.

If I'm awaken at 2am from being on-call for more than once per quarter, then something is seriously wrong and I will either fix it or quit.

Qualities of a good manager share a lot of qualities of a good engineer.

When I first started, I was enamored with technology and programming and computer science. I'm over it.

Good code is code that can be understood by a junior engineer. Great code can be understood by a first year CS freshman. The best code is no code at all.

The most underrated skill to learn as an engineer is how to document. Fuck, someone please teach me how to write good documentation. Seriously, if there's any recommendations, I'd seriously pay for a course (like probably a lot of money, maybe 1k for a course if it guaranteed that I could write good docs.)

Related to above, writing good proposals for changes is a great skill.

Almost every holy war out there (vim vs emacs, mac vs linux, whatever) doesn't matter... except one. See below.

The older I get, the more I appreciate dynamic languages. Fuck, I said it. Fight me.

If I ever find myself thinking I'm the smartest person in the room, it's time to leave.

I don't know why full stack webdevs are paid so poorly. No really, they should be paid like half a mil a year just base salary. Fuck they have to understand both front end AND back end AND how different browsers work AND networking AND databases AND caching AND differences between web and mobile AND omg what the fuck there's another framework out there that companies want to use? Seriously, why are webdevs paid so little.

We should hire more interns, they're awesome. Those energetic little fucks with their ideas. Even better when they can question or criticize something. I love interns.

Don't meet your heroes. I paid 5k to take a course by one of my heroes. He's a brilliant man, but at the end of it I realized that he's making it up as he goes along like the rest of us.

Tech stack matters. OK I just said tech stack doesn't matter, but hear me out. If you hear Python dev vs C++ dev, you think very different things, right? That's because certain tools are really good at certain jobs. If you're not sure what you want to do, just do Java. It's a shitty programming language that's good at almost everything.

The greatest programming language ever is lisp. I should learn lisp.

For beginners, the most lucrative programming language to learn is SQL. Fuck all other languages. If you know SQL and nothing else, you can make bank. Payroll specialtist? Maybe 50k. Payroll specialist who knows SQL? 90k. Average joe with organizational skills at big corp? $40k. Average joe with organization skills AND sql? Call yourself a PM and earn $150k.

Tests are important but TDD is a damn cult.

Cushy government jobs are not what they are cracked up to be, at least for early to mid-career engineers. Sure, $120k + bennies + pension sound great, but you'll be selling your soul to work on esoteric proprietary technology. Much respect to government workers but seriously there's a reason why the median age for engineers at those places is 50+. Advice does not apply to government contractors.

Third party recruiters are leeches. However, if you find a good one, seriously develop a good relationship with them. They can help bootstrap your career. How do you know if you have a good one? If they've been a third party recruiter for more than 3 years, they're probably bad. The good ones typically become recruiters are large companies.

Options are worthless or can make you a millionaire. They're probably worthless unless the headcount of engineering is more than 100. Then maybe they are worth something within this decade.

Work from home is the tits. But lack of whiteboarding sucks.

React Native testing is hair pulling.

Every test needs to have 100 different mocks in place and there are: 3 different methods to mock a function (mock, mockImplementation, and fn), 3 different types of query methods to get elements (get, find, and query), and 5 different selectors to query on (accessibility label, testId, accessibility hint, accessibility value, etc.)

And after reading all this, being diligent and learning the difference between stupid, synonymously-named functions which have wildly different side effects like "getByA11yHint" and "findByA11yHint" (ugh...), after all that, you write out a test with all the appropriate mocks and you want to do something simple and it beats you up all over again.

Button enabled or button disabled. Simple right? Logically the former is "expect(elem).toBeEnabled()" and the latter is "expect(elem).not.toBeEnabled()", right?

Wrong! You're an imbecile. Your tests will fail and never tell you that ".not.toBeEnabled()" and ".toBeDisabled()" don't do the same thing even though they look and sound exactly the same. Only the latter will work. The former makes all your tests fail. Where is this written in the docs? Nowhere?! Great!

I need to add new feature into the program which I wrote years ago so I start digging up the source code. The project is written in a language which I no longer code in.

That code is really poorly written with most of them don't have tests. I also find out that previous self is really a genius since he can keep track of huge project with almost no documentation.

To make matter worst, there are unused components (class,feature) in the source code. "Current me" have a policy of "just adding only a feature you need and remove unused feature" but it seem the "previous me" don't agree with the "current me".

The previous me also have the habit of using writing insane logic. I can remember what particular class and methods is doing but I can't figure out the details.

For example one method only have 5 line of code but it is very hard to figure out what those do.

The saving grace is that he know the important for method signature and using immutable data structure everywhere.

I was under the influence of caffeine and have a constant sleep deprivation at the time (only sleeping about 4 hour every day) so I can't blame him too hard.

I can't blame him too hard, right?

Could someone invent a time machine already? Invent time machine not to save the world but to save the developers from himself.
