Refactoring is something that should be constantly done in a code base, for every story. As soon as people get scared about changing things the codebase is on the road to being legacy.
Been with a lot of codebases that had no unit tests at all and everyone was afraid to change anything because the QA process could take weeks to months.
The result is you have a codebase that ages like milk.
Doesn’t everybody agree with this? I really never thought of it as a hot take.
Today I removed code from a codebase that was added in 2021 and never ever used. Sadly, some people are as content to litter in their repo as they are in the woods.
Only if the code base is well tested.
Edit: always add tests when you change code that doesn’t have tests.
If you don’t add comments, even rudimentary ones, or you don’t use a naming convention that accurately describes the variables or the functions, you’re a bad programmer. It doesn’t matter if you know what it does now, just wait until you need to know what it does in 6 months and you have to stop what you’re doing an decipher it.
However, engineers who rely solely on comments to explain their code, are bad at writing readable code.
Self documenting code is infinitely more valuable than comments because then code spreads with it’s use, whereas the comments stay behind.
I got roasted at my company when I first joined because my naming conventions are a little extra. That lasted for about 2 months before people started to see the difference in legibility as the code started to change.
One of the things I tell my juniors is, “this isn’t the 80s. There isn’t an 80 character line limit. The computer doesn’t benefit from your short variable names. I should be able to read most lines of code as a single non-compound sentence in English with only minor tweaks and the English sentence should be what is happening in most of those lines of code.”
it doesn’t matter if you don’t know what it does now
If I don’t know what it does now my comment of “I have no idea wtf this does” won’t help me in 6 months.
Programing is a lot less important than people and team dynamics
People can always be replaced, they’re irrelevant.
Sure try to replace the one or two people that hold the whole team together. I’ve seen it a couple times, a good team disintegrates right after one or two key people leave.
Also, if you replace half the team, prepare for some major learning time whenever the next change is being made. Or after the next deployment. 🤷♂️
The code can always be rewritten, it is irrelevant.
And it will change next week anyway. 😁
Python is only good for short programs
Python should not be used for production environments, or anything facing the user directly. You are only inviting pain and suffering.
SPAs are mostly garbage, and the internet has been irreparably damaged by lazy devs chasing trends just to building simple sites with overly complicated fe frameworks.
90% of the internet actually should just be rendered server side with a bit of js for interactivity. JQuery was fine at the time, Javascript is better now and Alpinejs is actually awesome. Nowadays, REST w/HTMX and HATEOAS is the most productive, painless and enjoyable web development can get. Minimal dependencies, tiny file sizes, fast and simple.
Unless your web site needs to work offline (it probably doesn’t), or it has to manage client state for dozen/hundreds of data points (e.g. Google Maps), you don’t need a SPA. If your site only needs to track minimal state, just use a good SSR web framework (Rails, asp.net, Django, whatever).
I’m still hoping for browsers to become some kind of open standard application environments and web apps to become actual apps running on this environment.
How are browser not that already? What’s missing?
They are an open standard and used to make many thousands of apps.
Not sure if these are hot takes:
- Difficult to test == poorly designed
- Code review is overrated and often poorly executed, most things should be checked automatically (review should still be done though)
- Which programming language doesn’t matter (within reason), while amount of programming languages matters a lot
Python, and dynamically typed languages in general, are known as being great for beginners. However, I feel that while they’re fun for beginners, they should only be used if you really know what you’re doing, as the code can get messy real fast without some guard rails in place (static typing being a big one).
Disagree on this one, even though I can see where you are coming from. I first learnt programming in Java, and it gave me massive problems to understand the structure and typings. Obviously Java isn’t the most beautiful language anyways, but once I picked up python it started to click for me on how to solve problems, because I didn’t have to think about that many things. I could just go for it. Yes, my code was messy in the beginning, but I wasn’t working on any important projects. It was just for fun.
So I think learning how to solve problems is as important as writing clean code. And python really helped me with that.
I’d actually argue Python stops people learning how to solve problems.
I love teaching juniors and have done so for 10 years but I’ve noticed in the last 4-5 years since Python became the popular choice at universities Graduates aren’t learning anything about Static Types, Memory Management, Object Oriented Programming, Data Encapsulation, Composition, Service Oriented Architecture, etc…
I used to expect most graduates to have a mixed grounding in those concepts and would find excuses for them to work on a small UI projects. I would do this as it gets them used to solving a small problem and UI’s give instant feedback. As Python became dominate university teaching language the graduates aren’t spending their time learning Typescript, Angular, HTML, etc… but instead getting overwhelmed by the concept of types.
Those concepts I want them to learn were created to help make solving problems easier and each has their strengths and weaknesses but most graduates are coming through only knowing how to lay out a small amount of procedural logic using Python and really struggling to move beyond that.
Compiler checked typing is strictly superior to dynamic typing. Any criticism of it is either ignorance, only applicable to older languages or a temporarily missing feature from the current languages.
Using dynamic languages is understandable for a lot of language “external” reasons, just that I really feel like there’s no good argument for it.
Until you know a few very different languages, you don’t know what a good language is, so just relax on having opinions about which languages are better. You don’t need those opinions. They just get in your way.
Don’t even worry about what your first language is. The CS snobs used to say BASIC causes brain damage and that us '80s microcomputer kids were permanently ruined … but that was wrong. JavaScript is fine, C# is fine … as long as you don’t stop there.
(One of my first programming languages after BASIC was ZZT-OOP, the scripting language for Tim Sweeney’s first published game, back when Epic Games was called Potomac Computer Systems. It doesn’t have numbers. If you want to count something, you can move objects around on the game board to count it. If ZZT-OOP doesn’t cause brain damage, no language will.)
Please don’t say the new language you’re being asked to learn is “unintuitive”. That’s just a rude word for “not yet familiar to me”. So what if the first language you used required curly braces, and the next one you learn doesn’t? So what if type inference means that you don’t have to write
inton your ints? You’ll get used to it.You learned how to use curly braces, and you’ll learn how to use something else too. You’re smart. You can cope with indentation rules or significant capitalization or funny punctuation. The idea that some features are “unintuitive” rather than merely temporarily unfamiliar is just getting in your way.

Well i mean… that’s kinda what “unintuitive” means. Intuitive, i.e. natural/obvious/without effort. Having to gain familiarity sorta literally means it’s not that, thus unintuitive.
I dont disagree with your sentiment, but these people are using the correct term. For example, python len(object) instead of obj.len() trips me up to this day because 99% of the time i think [thing] -> [action], and most language constructs encourage that. If I still regularly type an object name, and then have to scroll the cursor back over and type “len(”, i cant possibly be using my intuition. It’s not the language’s “fault” - because it’s not really “wrong” - but it is unintuitive.
If you only know C and you’re looking at Python, the absence of curly braces on code blocks is temporarily unfamiliar to you.
But if you only know Python and you’re looking at C, the fact that indentation doesn’t matter is temporarily unfamiliar to you.
Once you learn the new language, it’s not unfamiliar to you anymore.
“Unintuitive” often suggests that there’s something wrong with the language in a global sense, just because it doesn’t look like the last one you used — as if the choice to use (or not use) curly braces is natural and anything else is willfully perverse on the part of the language designer.
I am not smart enough to effectively code with certain languages and design patterns and that’s ok. There is nothing wrong with accessibility being prioritized or with making tradeoffs for the sake of reducing complexity.
Most modern software is way too complex for what it actually does.
Agile in it’s current implementation with excessive meetings wastes more time than the mistakes it tries to avoid.
My take is that no matter which language you are using, and no matter the field you work in, you will always have something to learn.
After 4 years of professional development, I rated my knowledge of C++ at 7/10. After 8 years, I rated it 4/10. After 15 years, I can confidently say 6.5/10.
Amen. I once had an interview where they asked what my skill is with .net on a scale of 1 - 10. I answered 6.5 even though at the time I had been doing it for 7 years. They looked annoyed and said they were looking for someone who was a 10. I countered with nobody is a 10, not them or even the people working on the framework itself. I didn’t pass the interview and I think this question was why.
As a hiring manager, I can understand why you didn’t get the job. I agree that it’s not a “good” question, sure, but when you’re hiring for a job where the demand is high because a lot is on the line, the last thing you’re going to do is hire someone who says their skills are “6.5/10” after almost a decade of experience. They wanted to hear how confident you were in your ability to solve problems with .NET. They didn’t want to hear “aCtUaLlY, nO oNe Is PeRfEcT.” They likely hired the person who said “gee, I feel like my skills are 10/10 after all these years of experience of problem solving. So far there hasn’t been a problem I couldn’t solve with .NET!” That gives the hiring manager way more confidence than something along the lines of “6.5/10 after almost a decade, but hire me because no one is perfect.” (I am over simplifying what you said, because this is potentially how they remembered you.)
Unfortunately, interviews for developer jobs can be a bit of a crap shoot.
They wanted to hear how confident you were in your ability to solve problems with .NET. They didn’t want to hear “aCtUaLlY, nO oNe Is PeRfEcT.”
Yeah, I mean no shit, with hindsight it’s obvious they were looking for the 10/10 answer. I was kicking myself for days afterwards because that’s the only question I felt I answered “wrong”. Tech interviews are such a shit show though that you can start to overthink things as an interviewee. Also, an important aspect of the question that I didn’t mention was they specified “1 is completely new, and 10 is working at Microsoft on the .net framework itself”. The question caught me off guard. I have literally no idea what working at Microsoft on the framework is like. In that context being a 10/10 felt like being among the most knowledgeable person of c# of all time. Could I work on the framework itself? Idk maybe, I’ve never thought about it, I don’t even know what their day to day is. I should’ve just said 10/10 though, it was a dev II position to work on a web app, it wouldn’t have been that hard.
10 is working at Microsoft on the .net framework itself.
An interesting spin. I like to imagine that you could have answered “10/10,” taken a pause, and declared that you’re leaving the interview early to apply directly to Microsoft to “work on the .net framework itself.” 🤓
dev II position to work on a web app
”we want you to tell us that you’re over qualified for the role”
Your mistake was giving them an answer instead of asking how the scale was setup before giving them a number. Psychologically, by answering first your established that the question was valid as presented and it anchored their expectations as the ones you had to live up to. By questioning it you get to anchor your response to a different point.
Sometimes questions like this can be used to see how effective a person will be in certain lead roles. Recognizing, explaining and disambiguating the trap question is a valuable lead skill in some roles. Not all mind you… And maybe not ones most people would want.
But most likely you dodged a bullet.
I was kicking myself for days afterwards for not doing exactly as you said. I’m not good at these types of interview questions in the moment. Also before that was the tech interview classic of asking a bunch random trivia questions, which I actually nailed. Also this was for dev II position.
I definitely dodged a bullet though. Some months later I got hired at a different company for 30k more.
Tools that use a GUI are just as good (if not better) than their CLI equivalents in most cases. There’s a certain kind of dev that just gets a superiority complex about using CLI stuff.
The big thing you can do from the command line is script it.
Computer hardware has been getting faster and faster for decades at this point, but my computer still slows down. Like WTF. The dumbass programmers take the extra power given to them and squander it instead of optimizing their code. Microsoft word could run pretty well on a windows 98 PC, but the new Word can slow down PCs that are 5-10 years old. Programmers are complete idiots sometimes…
