Drunk post: Things I've learned as a senior engineer (2021)

> The most underrated skill to learn as an engineer is how to document.

Document why. I can read code. I want to know _why_ this nebulous function called "invert_parameters" that is 200 lines long even exists. Which problem did you have that this function solved? Why was this problem there in the first place? Write some opinions on maybe its intended lifetime of the codebase. Hell, I write comments that apologize, just so that a future reader knows that the code I wrote wasn't meant to be great but that I was in a time crunch or a manager was breathing down my neck, or that some insane downstream/upstream thing did something... well, insane.

Paint some picture of your mindset when writing something, especially if it's non-obvious, as that'll give all the additional context not captured in code, when reading the code.

Obviously this isn't the only good documentation rule, but I wish people - juniors and seniors alike - would do this more often, especially at the workplace.

This is interesting. At my employer we see job hopping as a bad thing.

I think there's a unique perspective you get by seeing your 5+ year old code in production. I can kinda tell when someone only does short stints based on the way they talk about other people's code.

They probably also take home more income since they are getting raises more often which allows them to purchase free time to further hone their skills, rather than collecting a fixed wage and minimal equity from a corporation and the satisfaction of their work being minimally rewarded for five years.

> You know what the best part of being a software engineer is? You can meet and talk to people who think like you. Not necessarily the same interests like sports and TV shows and stuff. But they think about problems the same way you think of them. That’s pretty cool.

That hasn't really been my experience, for every 50 people I meet maybe 1 is here for the craft, the rest want to do 9-5, have a visibility at work, work on impactful projects but actually talk about their problems, their opinions in a deeper way - almost never.

As a child and adolescent I always imagined that something would click when I became an adult and I would become good at things and understand the world. That never happened, and then I realised it never happens for anyone. We're all just large children walking around figuring things out. Some of us figure things out faster, some of us stop trying to figure things out, but we're all just as clueless in the grand scheme of things. It's a miracle and a testament to our perseverance and ambition that things still work as well as they do.

On the other hand, I've contacted several of my heroes (not been able to meet as many of them in person) and that's always been an exhilerating, formative experience. I strongly recommend it if you can think of a good reason. (I have a list of heroes I have yet to reach out to because I haven't yet encountered an interesting enough problem to offer them. Several of them unfortunately have an actuarial deadline not too far into the future.)

I once worked with someone well renowned in my circles who gave talks, ran a blog, was cited/edited other peoples books.

His code did not match the hype, to say the least. His SDLC even less so.

There is probably an ego associated with being renowned that doesn't align with team-based work. He likened basic things like code reviews or PRs to being brought before The Hague and that the rest of the team was a bunch of bureaucrats.

I am not sure which profession they are in (software development?), but no. Not everybody is guessing. If they were you would have half of the buildings and bridges collapsing and the other half on fire by bad electrical wiring.

You can legitly learn how to do things properly and people who learnt to do that do the polar opposite of guessing. It is just that the world of software development has yet to be made liable for their results in the same way as civil or electrical engineers. So in software development many are just guessing because guessing wrong won't ruin their life.

Quite a few major issues with the post:

  - Drinking wine solo is odd. Whiskey, vodka, or beer (and if you Russian) is the standard. Spelling mistakes like 'ever thing' support the idea of alcohol induced unordered thoughts, that's good.
  - Webdevs would one of the last to consider to be experts.
  - While I don't use darkmode, browser extensions solve the unsupported web pages. Dark mode used to be the only possible option on a black/green screen, glad that changed.
  - Pharmacist require a degree and quite a few years of studies and exams with tons of organic chemistry. 
  - HN comments being worthless is an awkward one. Lots of posts (e.g. Apple CEO change) had tons of useless stuff but it's very often the comments would bve better than the post itself.

> Max out our 401ks

If there's any 20-somethings here that make 6 figures, listen carefully:

  1. Max out your 401k, and invest all of it in a target date retirement fund. (Some companies are douches and will assign you mostly their own stock, which when it tanks, there goes your retirement... so check your allocation)

  2. Get an HSA and max that out. Invest it all in a target date retirement fund. Do not use any of it, pay for medical expenses with cash and save your receipts. Get reimbursed for the receipts when you retire.

  3. Contribute to an IRA and max it out (or backdoor roth when you make enough that that's necessary). Invest it all in a target date retirement fund.

  4. Keep 6-12 months of living expenses in a high yield savings account.
If you start when you're 23, and you make $100k/yr, you can retire at 45. That may sound very old right now, and you might think, I'll just save later. But consider that when you turn 45, you may realize you have 20 more years of this shit job before you can retire.

by 0xbadcafebee

4/22/2026 at 12:51:04 PM

> you can retire at 45

Kinda hard to do that when you've locked all your money up in a retirement vehicle that doesn't let you withdraw until age 59.5.

by silverquiet

4/22/2026 at 4:30:08 AM

Even with this strategy, you're not retiring at 45 unless you are frugal, have cheap hobbies, and never have kids or a non-working spouse. Also take care that you don't have any parents, siblings, or extended family that come to rely on you. Also don't forget expect to live anywhere even remotely expensive, unless you like camping.

by paulryanrogers

4/22/2026 at 6:36:59 AM

You're not wrong, a family is more expensive. But if both parents pull the same (or similar) salary, it is enough to still retire at 45. Requires using more tax-advantaged plans to play for college, and may not work well in expensive cities.

Re: cheap hobbies, I used to date a public school teacher. She would save to go on guided trips to Antarctica, Peru, the Galapagos, New Zealand. You can live an amazing life if you plan for it.

by lynx97

4/22/2026 at 7:18:19 AM

The median household income in the US is $83,730 [1] - half of households are on less than that.

If you earn $100k and are willing to have the median lifestyle, and you can find a spouse that's willing, then the numbers work just fine.

Challenges include lifestyle inflation; housing costs if your six-figure job is in an expensive area; and finding a partner who's willing to be put in what is often a vulnerable and low-status position.

I don’t think these methods are possible anymore in this modern economy of “fire everyone because of AI and then rehire them a few months later at half the salary”.

If you’re not one of the senior managers, I don’t think these kinds of long term investments are feasible anymore.

by rcbdev

4/22/2026 at 7:44:47 AM

I feel like this is a bit snarky, it simply means plan for your retirement and invest in your own future, take advantage of government / employer backed savings plans. Plenty of these exist over here. Don't waste your money.

Everything is not perfect in the singular country of Europe, I sure as hell don't want to be relying on only what the state decides it can give me in my old age.

by alibarber

4/22/2026 at 11:52:07 AM

All is fine in Switzerland, there is state part (1st pillar) where people give blindly and then during retirement get some payment; and then mandatory private part where employer contributes too, often the same amount (2nd pillar) which is the most important one. Also another optional private 3a pillar which otherwise behaves like 2nd. Obviously all of this is pre-tax, 2nd and 3rd can be used for purchasing primary property or start business etc. State is always a miserable manager of longterm funds. One can pick investment profile for those savings, or is voted by employees' assembly in case of 2nd.

No complaints, I know how much I saved, projections on how my pension will look like if I retire in year X, Y or Z. I don't expect more from a good social security system if one wants more it should be on them.

So far plan is retiring at 60, already I work on 90% and thus sporting 10 weeks of paid vacations yearly. That way, I don't thread the knife edge of burnout, in contrary and have plenty of time to unwind, have adventures (just came back from 2 weeks road trip in Dominican republic) and spend literal months on vacations with my kids and wife. There is no salary achievable in our field that would force me to consider it a better setup and instead working hard... these are best years of my remaining life and waste them just working would be tremendously stupid and shortsighted. To retire in 45, seeing my skills atrophied and being at the mercy of things like inflation... doesn't sound that great.

So there is another perspective to just chasing biggest paycheck at all costs.

by kakacik

4/22/2026 at 11:44:42 AM

At this point I am losing faith in my (european) pension system; state pensions will get emptied out for the boomer generation currently enjoying the returns of the good times, private / employer paid for pensions will likely get raided and tanked by big investors / capitalism. I don't feel like I can trust or rely on them for when I might be able to retire in my 70's.

(that's the other thing, state pension age is being pushed back as life expectancy increases. Not for the main boomer generation of course, they were already retired when the age started to creep up or only had to work a few months longer)

they're pointing out that the US is insanely stupid when it comes to healthcare and retirement. the stuff we do in this country is so much extra work/effort/cost and all of it comes at the worker's cost.

they were being sarcastic.

by chrneu

4/22/2026 at 6:46:20 AM

My reading was that nothing of that applies in Europe. No earning 6 figures, no way to invest pre-tax or in any other tax advantaged way, no way to optimize healthcare costs, early retirement unlikely.

by distances

4/22/2026 at 11:50:57 AM

There are options to save extra for retirement, if you take a private pension or a bank account that you can't withdraw from until retirement for example; in that case, you don't pay wealth tax and only pay taxes when it starts paying out. Sometimes the money you put into it is tax deductible, too. But, that's in NL, I don't know anywhere else. Source: https://www.nibud.nl/onderwerpen/pensioen/pensioen-opbouwen/

6 figures is possible, there are/were some software companies (VC backed, US based, US startup style, FAANG) that pay that much, otherwise there's highly paid jobs like management, doctors/dentists, landlord, public motivational speaker, drug dealer, etc that can earn you that much. But it's not handed to you like it feels like it is in the US / SF, but I realize that's very much a unique bubble.

So yeah, basically none of your comment is true, it's just not talked about as much because our basic systems are alright for most people and few have the extra income to think about doing more with it.

by Cthulhu_

4/22/2026 at 7:38:13 AM

Retirement accounts are a thing in Europe though. In Poland for example there's IKE and IKZE. IKE is a bit simpler of the two. If you hold your money on IKE until you're 60 you're not paying taxes on that. Can invest in stocks or bonds.

by urxvtcd

4/22/2026 at 8:29:11 AM

Yes, as always it depends on the country. Germany and a bunch of others have nothing except completely useless insurance/capital guaranteed options.

For investments, you invest post-tax and pay capital gains when withdrawing.

Ah yes, the good old US of A where a 23 year old can start out making $100k/yr.

While here I am, 39yo, having been in this field for 17 years and worked my way up to a lead, and having worked at banks, fintechs, medtechs and consultancies, am 'only' making roughly €76k/yr.

And this is with pouring personal time into studying and applying latest tech in side projects to stay relevant.

$1.8M-$2.2M. Assumes 6%-7.5% annual return. Does not include employer contribution. Provides $72k-$88k /yr income. Assuming you pull social security at 67, your continued gains exceed your draw, and your fund perpetuates until you die.

by rjbwork

4/22/2026 at 8:19:27 AM

Especially when companies over-provision their databases. Partially because the jump from cheap-ass to mid-tier is a massive increase in capacity.

Then you can offload stuff to the DB engine (as it should be), making everything more efficient, less data going between DB and App layers is good for everyone.

- I agree, 100%.

by freakynit

My biggest lessons I've learned as non-senior non-engineer:

1. You'll never be as smart as the smart guys. It's okay to give up.

2. Most likely you'll work with incompetent fools, get used to that.

3. Workplace is the best place to make friends. If someone tells you otherwise it's a psyop to turn you into a robot.

4. Minimize your output while trying to maximize your salary because mythical "job satisfaction" doesn't exist and it makes much more sense to redirect your energy elsewhere.

5. Luck is the most important factor.

There is nothing I've done at work I'm truly proud of. Everything I'm proud of is completely unrelated to work.

Some good points. Laughed at TDD is a cult. I mean a lot of software orgs/cultures are cultish (Agile, Scrum, whatnot). At work I often feel I'm part of a cult.

On the contrary, I find "The older I get, the more I appreciate dynamic languages. Fuck, I said it. Fight me." is exactly my sentiment too, with a caveat. I really like gradual typing, like python has. And not like ruby has (where it's either RBS files and it's tucked away, or it's sorbet and it's weird).

The worst code base I had to work in by far was a Python code base. Extremely difficult to refactor. Many bugs that were completely avoidable with static typing. I think maybe more modern Python is a little bit better but wouldn't be my choice for large projects. It's not just about correctness. It's also about performance. That code was so slow and that impacted our business.

Refactoring is a young mans game. I either nuke it and start over or treat it as a black box.

You can just as easily take a static language dynamic - in userland.

I've interop'd with JS from Haskell and you can just go full dynamic property access. And gradually add phantom typed APIs around it.

I debug in ghci mostly

console.log also still works fine

One rebuttal to that is that with the benefit of hindsight, to a first approximation zero percent of the code I've written in my career turned out to be "of any significance" really.

Same. That line about "your legacy is your family and friends" hit hard.

I've been coding professionally for >30 years. I don't think any of my code has survived 5 years in production.

I don't think code quality affected that at all - I know the really, really, shitty code I wrote when learning OOP in the 90's survived for a looong time, while the amazing code I wrote for a startup 2018-2021 died with it.

One of the projects I'm most proud of is still running ten years later, and has processed over a billion AUD through it in that time, with very minimal maintenance. I recently consulted on it, and sure enough it's still ticking along nicely! The code is honestly quite good too, even if it is PHP (though in a very nice microframework we wrote on top of Silex: removed all magic that a lot of these systems relied on. No annotations!)

I haven't doing this forever (only 10+ years) but surprisingly I think a majority of what I've written is still running. Probably a fair bit will continue to run for a while yet too I think (again, surprising for CRUD web apps).

Most code I wrote over my career got pretty decent use and produced value for customers. Some was used by millions of people. What I work on today is used by thousands. It's important that it is of reasonable quality with less bugs, decent performance, functionality users are looking for etc.

A lot of code makes a difference but I guess there's a lot that doesn't?

I'd guess, on average, code I've written has a half-life of maybe 3 or 4 years. There's pretty much none of my code (with a few surprising exceptions) that's still been running or in production anywhere for more than 8 or 10 years.

At the time, a lot of it felt "important" and "significant". And some of it probably was at the time, to the businesses I wrote it for. But whether I sweated blood and tears to craft the most elegant and efficient software I was capable of, or I phoned it in and just copy/pasted Stack Overflow answers together until I met some interpretations of a requirement to be able to leave the office on time - really made no difference.

I've been pondering lately, thinking about GenAI and vibe coding, with the very real risk of creating completely unmaintainable codebases - whether that matters, if the code is likely to be retired or rewritten in 3-4 years anyway? My current gig is on to the 4th rewrite of it's web/mobile app backend platform in 15 years, which started out as a Groovy on Grails app, which got rewritten in Java, then rewritten again in Java, and now it's being rewritten in Python. Each rewrite had fairly good reasons at the time, but a huge amount of code here gets thrown away every 4 years or so - which looking back makes me seriously question whether any of it was "of any significance". To be honest, the 2026 Python code really isn't doing anything notably different or more complex than the Perl and JavaScript code I was writing in 1996 - web work is CRUD apps all the way down.

As a person who started in a dynamic language (PHP; don't laugh, it's actually really good for web dev) and worked in an infrastructure team which had to do a lot of refactoring... I can't agree with the sentiment either. Dynamic languages _look_ good, but lightly typed languages like Go strike a much better balance in my opinion

A lot of startups are cults. Tesla maybe the final form of a culted startup where the stock owners don't care about anything anymore.

That said, the people who change companies aren't the ones that believe that management ever had the best ideas, or are able to push back on the cult thinking with clarity. Unfortunately, though, it's not necessarily evidence that wins arguments, it's charisma, which is how the cult is started in the first place.

TDD is a cult. But knowing your pre-conditions an post-conditions for your isolated parts of your code is important. I think all your AI codegen will work better with this.

The entire AI ball of wax is built on python (dynamically typed) - or at least a large part of it. It probably needs to move to rust to save on power and compute cost.

The heavy lifting of AI is done by GPUs that are not running Python. But yes, a lot of orchestration and glue work is done by Python. Python can be a decent glue language and it has its place. But if the core/high performance logic of inference and training was written in Python then we wouldn't have today's AI. I imagine there are other languages in the mix.

Python is also the choice of non-programmers for simple work. Nothing wrong with that. But I wouldn't want e.g. my car's ABS system to be programmed in Python (or my browser or my OS or many other examples).

> But knowing your pre-conditions an post-conditions for your isolated parts of your code is important.

Design-by-Contract[0] is a formalization of this concept and well worth considering when working in code using mutable types. In addition to pre/post conditions, DbC also reifies class invariants (which transcend method definitions).

> 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.)

Good docs are docs that make it easy to implement the next feature.

From an AI perspective, it's my observation that LLMs often write code with lower quantity / quality docs. At the same time, they are reasonably good at synthesizing / inferring meaning from code that lacks good docs. They often do so internally by forming a chain of thought / reasoning around how the code works. The docs that should be written as part of the code are probably the same things that an LLM would reasonably come to by spending tokens when modifying that code. I believe that this should be trained into model so that future LLM work starts with not having to build up context.

In the absence of that being built in, something I've been experimenting a little with is tuning what I want to see in docs that actually help source control / development. Currently that's at https://github.com/joshka/skills/tree/main/doc-steward - still needs a bunch of work, but it's generally better than nothing. YMMV

This genuinely looks like that I wrote it...until I saw that LISP line, definitely not me. But do agree with a lot of items in the list, and I happen to be a DE, too.

I am a big fan of learning LISP, at least once. Going through SICP after more than a decade of writing code for a living was probably the single best thing I did to deepen my understanding of a lot of compsci concepts, data structures, and how to think about software. For me, at least, it was very much a seeing the matrix for the first time kind of moment. My LISP use has quickly declined, but I've dabbled in dozens of programming languages since then, and I do attribute not feeling lost to that experience.

this is probably the best truth. after a while it's easy to recognize people that are consistently being their "authentic self" and they're usually the worst.

"HR" does not set your professional obligations. If you need to be drunk to talk this honestly, you are not a "senior" nor a mentor, but an incipient alcoholic and a coward.

Then again, this person is obviously also lying to claim the engineer title - sit down, "data science!" You're only even here because Product prefers being lied to - so that really sets an ironically honest baseline on how seriously anyone should be taking any of this farrago.
