Hi everyone, long time no see.

Today I want to tell you a story about Linux, and its acceptance on the desktop.

Long ago I found myself a girlfriend, a wonderful woman who is an engineer too but who couldn't be further from CS. For those in the know, she absolutely despises architects. She doesn't know the size units of computers, i.e. the multiples of the byte. Breaks cables on the regular, and so on. For all intents and purposes, she's a user. She has written some code for a college project before, but she is by no means a developer.

She has seen me using Linux quite passionately for the last year or so, and a few weeks ago she got so fed up with how Windows refused to work on both her computers (on one of them literally failing to run exe's, go figure), that she allowed me to reinstall both systems, with one of them being dualbooted Windows 10 + Linux.

The computer that runs Linux is not one she uses very often, but for gaming (The Sims) it's her platform to go. On it I installed Debian KDE, for the following reasons:
- It had to be stable as I didn't want another box to maintain.
- It had to be pretty OOTB, as first impressions are crucial.
- It had to be easy to use, given her skill level.
- It had to have a GUI abstraction to apt, the KDE team built Discover which looks gorgeous.

She had the following things to say about Linux, when she went to download The Sims from a torrent (I installed qBittorrent for her iirc).

"Linux is better, there's no need to download anything"
"Still figuring things out, but I'm liking it"
"I'm scared of using Windows again, it's so laggy"
"Linux works fine, I'm becoming a Linux user"

Which you can imagine, it filled me with pride. We've done it boys. We've built a superior system that even regular users can use, if the system is set up to be user-friendly.

There are a few gripes I still have, and pitfalls I want to address. There's still too many options, users can drown in the sheer amount of distro's to choose from. For us that's extremely important but they need to have a guide there. However, don't do remote administration for them! That's even worse than Microsoft's tracking! Whenever you install Linux on someone else's computer, don't be all about efficiency, they are coming from Windows and just want it to be easy to use. I use Mate myself, but it is not the thing I would recommend to others. In other words, put your own preferences aside in favor of objective usability. You're trying to sell people on a product, not to impose your own point of view. Dualboot with Windows is fine, gaming still sucks on Linux for the most part. Lots of people don't have their games on Steam. CAD software and such is still nonexistent (OpenSCAD is very interesting but don't tell me it's user-friendly). People are familiar with Windows. If you were to be swimming for the first time in the deep water, would you go without aids? I don't think so.

So, Linux can be shown and be actually usable by regular people. Just pitch it in the right way.

3D printing factory + openSCAD web interface + cloud computing

Functional-Declarative languages should only be esoteric ones. They are interesting for research and a mathematical toy, but they should not be used for programming languages used in the real world.

I currently try to write OpenSCAD code that places a list of modules, with information given from an array, with varying sizes next to each other. And is so hard and cumbersome. Whoever had the idea to cripple OpenSCAD by not having variables was stupid or sadistic.

The actual CPU run instructions, one after the other, there is no good reason to not allow some imperative elements in a programming language.

Anyone ever heard of OpenSCAD? If you have, there's a clone called Scorch CAD on Android - I both love and hate the thing. Okay, it's awesome to be able to write 3D programs on my phone, but mother of god, why is it closed source?! I mean, surely that's a GPL violation. I'm contacting the developer. He makes no money off it anyway - why is it proprietary?! Urgh.
