As most of you already know, I'm a writer. I've noticed the similarities between writing and programming:
1. Tabs vs spaces.
2. Both typically spend all their time with a single project.
3. Coffee... (Unless you're a tea lover like me.)
4. Both typically have no life.
5. Debugging is hell for programmers and editing/revising is hell for writers.
6. Strict clients for programming and strict editors for writing.
7. Semicolons... They're useful but everyone despises them.
8: Emotions. Programmers are angry at their code. (Why won't you work?) and writers feel depressed about their writing. (Why did you die?)
9. War of the programs. For programmers: Vim vs VScode vs Atom vs Sublime and etc. For writers: MS word vs Google docs vs Libre office and etc.
10. Online forums. Stack overflow and Writer's digest.
11. Typing... Typing... All day long.
These are only a few similarities. I've noticed a lot more than this.16 -
Dear Programming Languages,
if you only support weakly typed constructs, I wish you a special place in hell.
Dear Fellow Developers,
if you use a language that allows strong typing with weak typing, the next time we will meet after I have to fix a shitty bug due to that I will play piano on your teeth, and a melody you won't like.
And yes, that means PHP as well. PHP allows for strict types since php7.
So. Just. Fucking. Use. It.
There are no excuses!
I don't care if you don't see the benefit or find it "annoying" and tedious to write it out. Use a decent editor and it will be mostly code-completion anyway.
I just don't want to fix your fuckups. And if your fuckup is due to a typing issue that "slipped" by, you are part of the problem.
If you write software, it should be clear what type each and every variable or object has.
There are no excuses but your laziness.
If you want to be ambiguous, try poetry.23 -
Let the student use their own laptops. Even buy them one instead of having computers on site that no one uses for coding but only for some multiple choice tests and to browse Facebook.
Teach them 10 finger typing. (Don't be too strict and allow for personal preferences.)
Teach them text navigation and editing shortcuts. They should be able to scroll per page, jump to the beginning or end of the line or jump word by word. (I am not talking vi bindings or emacs magic.) And no, key repeat is an antifeature.
Teach them VCS before their first group assignment. Let's be honest, VCS means git nowadays. Yet teach them git != GitHub.
Teach git through the command line. They are allowed to use a gui once they aren't afraid to resolve a merge conflict or to rebase their feature branch against master. Just committing and pushing is not enough.
Teach them test-driven development ASAP. You can even give them assignments with a codebase of failing tests and their job is to make them pass in the beginning. Later require them to write tests themselves.
Don't teach the language, teach concepts. (No, if else and for loops aren't concepts you god-damn amateur! That's just syntax!)
When teaching object oriented programming, I'd smack you if do inane examples with vehicles, cars, bikes and a Mercedes Benz. Or animal, cat and dog for that matter. (I came from a self-taught imperative background. Those examples obfuscate more than they help.) Also, inheritance is overrated in oop teachings.
Functional programming concepts should be taught earlier as its concepts of avoiding side effects and pure functions can benefit even oop code bases. (Also great way to introduce testing, as pure functions take certain inputs and produce one output.)
Focus on one language in the beginning, it need not be Java, but don't confuse students with Java, Python and Ruby in their first year. (Bonus point if the language supports both oop and functional programming.)
And for the love of gawd: let them have a strictly typed language. Why would you teach with JavaScript!?
Use industry standards. Notepad, atom and eclipse might be open source and free; yet JetBrains community editions still best them.
For grades, don't your dare demand for them to write code on paper. (Pseudocode is fine.)
Don't let your students play compiler in their heads. It's not their job to know exactly what exception will be thrown by your contrived example. That's the compilers job to complain about. Rather teach them how to find solutions to these errors.
Teach them advanced google searches.
Teach them how to write a issue for a library on GitHub and similar sites.
Teach them how to ask a good stackoverflow question :>6 -
all that decades spent on debuggers, strict typing, static analyzers, fucking unit tests
ima put frogs in my code so they eat bugs

I'm really tired of all the hype that Python lately gets, mostly by begginers or at most mediors.
I get that a lot of people like it's syntax, but it has just a few use cases where it really shines (like CI scripting or ML). In other cases it always has a much better and much more mature alternative.
As a web developer I would always pick PHP over Python. It has really mature frameworks like Symfony or Laravel which are using PSR standards, well documented and implemented common patterns, option for strict typing and probably most importantly tons of libraries for pretty much everything. For example I could find implementation of payment gate for even the smallest banks in our country, thus saving several days of implementing it myself. And PHP will always humiliate Python in performance. Yet, pretty much every comparison article of those two will state Python as better option for webdev, mostly because it is evident that the person who wrote the article never even tried to do a proper atleast midsized project in PHP, but has ton of experience in Django.
And what exactly is my point? There are two in fact:
1) You should always use the right tools for the job.
2) Even if you could do something doesn't mean you should do it.
In the end of the day I shouldn't really be bothered by people hyping Python, but those fanatics really made me hate the language, even if I would normally consider looking into it.8 -
I've ranted about this before, but here we go again:
Go Plugins.
I was racking my brains trying to figure out how one could possibly implement plugins easily in Go.
I had a look at using RPC, which requires far to much boilerplate to be realistic. I looked at using Lua, but there doesn't seem to be a straight forward way of using it. I was even about to go with using WASM (yes, WASM). But then I came across Yaegi ("Yet another elegant Go interpreter", you heard right: "interpreter"), Yaegi is also very easy to use.
There are a few issues (including some I haven't solved yet), including flexibility (multiple types of plugins), module support, etc. Fortunately, Traefik just released their plugin system which is based on Yaegi (same company), and I got to learn a few tricks from them.
Here's how module loading works: The developer vendors their dependencies and pushes them to a repo. The user downloads the repo as a zip and saves it to the plugins folder. I hash the zip, unzip it to a cache, and set the the GOPATH for the interpreter to be that extracted folder. I then load the module (which is defined by a config file in the folder), and save it for later. This is the relatively easy part.
The hard part is allowing for different types of plugins. It looks easy, but Go has a strict typing system, makes things complicated. I'm in the process of solving this problem, and so far it should go like this: Check that the plugin fits an arbitrary interface, and if it does, we're good the go. I will just have to apply the returned plugin to that interface. I don't like this method for a few reasons, but hopefully with generics it will become a bit more clean.1 -
Rant!!!
Recently, there has been this issue on StackOverflow not been friendly to beginners. I don't fully agree with that. SO is strict and rightly so because if not that, we will be flooded with repeated questions and low value answers. As a programmer, I believe when I go to SO, I want an answer quickly and fast because most at times, I'm programming and the problem I have is preventing me from moving forward. To be flooded by repeated and low quality questions and answers wouldn't help anyone. Also, on most beginner programming tutorials, were people are advised to check sites like SO when they have problems, most of them tell their listeners or readers to check if the question has been asked before, before going ahead to ask. Even SO assists you when typing your question with similar questions just to make sure you don't ask repeated questions. I rarely downvote but I understand those who do. Also, there is this talk about 'inclusivity' and some relating it to gender. It looks like people tend to slap gender and race on everything these days. To make this clear, I'm not a white male so that one wouldn't say the system favors me so I don't see the problem. The fact SO collects data about developers and it comes out that, most of the partakers are males doesn't mean SO is favoring males. SO doesn't show your gender when you ask a question. It doesn't even show your gender in your profile so what's the issue here? It will be better to get to the root of why there are few females in computer engineering and solve it there rather than blaming a site because of data collected. To know where this rant is coming from, just search StackOverflow on twitter and read the recent tweets.6 -
Worst / best feature of any language:
Lack of / requirement of strict / dynamic / weak / strong typing. Just typing. Typing typing typing just typing.
Having to specify the type in C/++/#, Java/Kotlin is so annoying and delays the project so much by having to do declare weird classes with 3 or 4 fields just because you need it in this tiny line of code.
Not having good type support in JavaScript and Python is a pain in the eyes when you can't find what type each variable is, or when you pass a wrong argument to a function, and when you do, it shows the definition for the type in a .ty or.pyi file and not the definition itself which you have to find elsewhere. Spent half of my uni exams trying to decipher the type while it could've been a piece of cake if you just knew the type.
