I think that two criterias are important:

- don't block my productivity
- author should have his userbase in mind

1) Some simple anti examples:

- Windows popping up a big fat blue screen screaming for updates. Like... Go suck some donkey balls you stupid shit that's totally irritating you arsehole.
- Graphical tools having no UI concept. E.g. Adobes PDF reader - which was minimalized in it's UI and it became just unbearable pain. When the concept is to castrate the user in it's abilities and call the concept intuitive, it's not a concept it's shit. Other examples are e.g. GEdit - which was severely massacred in Gnome 3 if I remember correctly (never touched Gnome ever again. I was really put off because their concept just alienated me)
- Having an UI concept but no consistency. Eg. looking at a lot of large web apps, especially Atlassian software.
Too many times I had e.g. a simple HTML form. In menu 1 you could use enter. In menu 2 Enter does not work. in another menu Enter works, but it doesn't submit the form it instead submits the whole page... Which can end in clusterfuck.
Yaaayyyy.
- Keyboard usage not possible at all.
It becomes a sad majority.... Pressing tab, not switching between form fields. Looking for keyboard shortcuts, not finding any. Yes, it's a graphical interface. But the charm of 16 bit interfaces (YES. I'm praising DOS interfaces) was that once you memorized the necessary keyboard strokes... You were faster than lightning. Ever seen e.g. a good pharmacist, receptionist or warehouse clerk... most of the software is completely based on short keyboard strokes, eg. for a receptionist at a doctor for the ICD code / pharmaceutical search et cetera.
- don't poop rainbows. I mean it.
I love colors. When they make sense. but when I use some software, e.g. netdata, I think an epilepsy warning would be fair. Too. Many. Neon. Colors. -.-

2) It should be obvious... But it's become a burden.

E.g. when asked for a release as there were some fixes... Don't point to the install from master script. Maybe you like it rolling release style - but don't enforce it please. It's hard to use SHA256 hash as a version number and shortening the hash might be a bad idea.

Don't start experiments. If it works - don't throw everything over board without good reasons. E.g. my previous example of GEdit: Turning a valuable text editor into a minimalistic unusable piece of crap and calling it a genius idea for the sake of simplicity... Nope. You murdered a successful product.
Gnome 3 felt like a complete experiment and judging from the last years of changes in the news it was an rather unsuccessful one... As they gave up quite a few of their ideas.

When doing design stuff or other big changes make it a community event or at least put a poll up on the github page. Even If it's an small user base, listen to them instead of just randomly fucking them over.

One of my favorite projects is a texteditor called Kate from KDE.

It has a ton of features, could even be seen as a small IDE. The reason I love it because one of the original authors still cares for his creation and ... It never failed me. I use Kate since over 20 years now I think... Oo

Another example is the git cli. It's simple and yet powerful. git add -i is e.g. a thing I really really really love. (memorize the keyboard shortcuts and you'll chunk up large commits faster than flash.

Curl. Yes. The (http) download tool. It's author still cares. It's another tool I use since 20 years. And it has given me a deep insight of how HTTP worked, new protocols and again. It never failed me. It is such a fucking versatile thing. TLS debugging / performance measurements / what the frigging fuck is going on here. Take curl. Find it out.

My worst enemies....

Git based clients. I just hate them. Mostly because they fill the niche of explaining things (good) but completely nuke the learning of git (very bad). You can do any git action without understanding what you do and even worse... They encourage bad workflows.
I've seen great devs completely fucking up git and crying because they had really no fucking clue what git actually does. The UI lead them on the worst and darkest path imaginable. :(

Atlassian products. On the one hand... They're not total shit. But the mass of bugs and the complete lack of interest of Atlassian towards their customers and the cloud movement.... Ouch. Just ouch.

I had to deal with a lot of completely borked up instances and could trace it back to a bug tracking entry / atlassian, 2 - 3 years old with the comment: vote for this, we'll work on a Bugfix. Go fuck yourself you pisswads.

Microsoft Office / Windows. Oh boy.
I could fill entire days of monologues.
It's bad, hmkay?

XEN.
This is not bad.
This is more like kill it before it lays eggs.
The deeper I got into XEN, the more I wanted to lay in a bathtub full of acid to scrub of the feelings of shame... How could anyone call this good?!?????

How to delete 16 days of commits 101 🤯:

First of all, me and my class (computer science in college) were working on a project for around 12 weeks, our “client” is one of our teacher and we literally just finished today to work on the project since our degree terminal projects are starting next week.

So now there's this guy in our class who kinda has the reputation to be stuborn and clumsy; he’s going to do his assigned task, commit, push it and put his task into QA (which is just peer evaluation and testing nothing really complex) and then when we try his functionality and finds out it isn’t working, we tell him and the only thing he always answers is : “but it works on my machine” and then we will need to explicitly ask him to be sure he has all the latest changes (database and codebase) and to see if it still works on his side since it doesn’t work for anyone else.

This actually happened quite a lot in these 12 weeks and you can definitely imagine that of course it would definitely not happen again today when we thought we were finally done with this project…

So another teacher gave us an assignment to create a development environment for our big project so we could try out Docker instead of virtual machines, he made GitHub Classroom repos with a minified version of our project and up to this point everything is fine and clear. That is until 3 hours ago, that our little clumsy friend somehow pushed his Docker related files on the main project, maybe he was trying his Docker setup on the real project no big deal you know EXCEPT IF HE HADN’T NOT PULLED SINCE 16 DAYS 😤.

He was doing maintenance on another project so I can maybe understand but gosh how did he not see the big warning of Git that he wasn’t up to date with master ? And yes we only have a master branch bear with us but hopefully we were able to create a new branch with the up to date project and then merge master.

A couple of us had a gut feeling that this guy would do something that would break the whole project right before we ended, turns out we were right 😅

Almost. There.

Should hit 2,000 by the time I finish wrap up my next two projects!

To me this is one of the most interesting topics. I always dream about creating the perfect programming class (not aimed at absolute beginners though, in the end there should be some usable software artifact), because I had to teach myself at least half of the skills I need everyday.

The goal of the class, which has at least to be a semester long, is to be able to create industry-ready software projects with a distributed architecture (i.e. client-server).

The important thing is to have a central theme over the whole class. Which means you should go through the software lifecycle at least once.

Let's say the class consists of 10 Units à ~3 hours (with breaks ofc) and takes place once a week, because that is the absolute minimum time to enable the students to do their homework.

1. Project setup, explanation of the whole toolchain. Init repositories, create SSH keys for github/bitbucket, git crash course (provide a cheat sheet).
Create a hello world web app with $framework. Run the web server, let the students poke around with it. Let them push their projects to their repositories.
The remainder of the lesson is for Q&A, technical problems and so on.

Homework: Read the docs of $framework. Do some commits, just alter the HTML & CSS a bit, give them your personal touch.
For the homework, provide a $chat channel/forum/mailing list or whatever for questions where not only the the teacher should help, but also the students help each other.

2. Setup of CI/Build automation. This is one of the hardest parts for the teacher/uni because the university must provide the necessary hardware for it, which costs money. But the students faces when they see that a push to master automatically triggers a build and deploys it to the right place where they can reach it from the web is priceless.
This is one recurring point over the whole course, as there will be more software artifacts beside the web app, which need to be added to the build process. I do not want to go deeper here, whether you use Jenkins, or Travis or whatev and Ansible or Puppet or whatev for automation. You probably have some docker container set up for this, because this is a very tedious task for initial setup, probably way out of proportion. But in the end there needs to be a running web service for every student which they can reach over a personal URL. Depending on the students interest on the topic it may be also better to setup this already before the first class starts and only introduce them to all the concepts in a theory block and do some more coding in the second half.

Homework: Use $framework to extend your web app. Make it a bit more user interactive with buttons, forms or the like. As we still have no backend here, you can output to alert or something.

3. Create a minimal backend with $backendFramework. Only to have something which speaks with the frontend so you can create API calls going back and forth. Also create a DB, relational or not. Discuss DB schema/model and answer student questions.

Homework: Create a form which gets transformed into JSON and sent to the backend, backend stores the user information in the DB and should also provide a query to view the entry.

4. Introduce mobile apps. As it would probably too much to introduce them both to iOS and Android, something like React Native (or whatever the most popular platform-agnostic framework is then) may come in handy. Do the same as with the minimal web app and add the build artifacts to CI. Also talk about getting software to the app/play store (a common question) and signing apps.

Homework: Use the view API call from the backend to show the data on the mobile. Play around with the mobile project to display it in a nice way.

5. Introduction to refactoring (yes, really), if we are really talking about JS here, mention things like typescript, flow, elm, reason and everything with types which compiles to JS. Types make it so much easier to refactor growing codebases and imho everybody should use it.
Flowtype would make it probably easier to get gradually introduced in the already existing codebase (and it plays nice with react native) but I want to be abstract here, so that is just a suggestion (and 100% typed languages such as ELM or Reason have so much nicer errors).
Also discuss other helpful tools like linters, formatters.

Homework: Introduce types to all your API calls and some important functions.

6. Introduction to (unit) tests. Similar as above.
Homework: Write a unit test for your form.
