I had one Windows machine left in my living room for my son's gaming needs, but like things go in the Windows 11 era, certain games stopped working all together, and the Linux opportunity has risen once again, I installed CachyOS there, my son has been once again a happy camper.

I have been using Fedora, Ubuntu, Gentoo, Sabayon, Debian, Aptosid, Arch, .... but none of them come even close to NixOS that I am using for last years, the stability - I havent re-installed NixOS to this day on any computer, still running the original installations, the rollbacks after each system upgrade are great if you want to go back, even several upgrades back. On this system, do you want Docker? Turn it on in the system configuration file like with virtualisation.docker.enable = true; option. Do not want it anymore on your system? Just delete that option or set it to false. Want fingerprint daemon? services.fprintd.enable = true; want iptables? networking.firewall.enable = true; you get the point... you want to fix a bug or add a new feature? clone nixpkgs and make a pull request, the community is very active. But there is one downside to use NixOS like an advanced user you will have to know Nix (talking about the language), learning curve can get steep quite fast, but once you get it you can make any change.Desktop Environment:
Like distros, I have been using all sorts of them: Gnome2, Gnome3, Mate, XFCE, Enlightenment, KDE 3,4,5..., for all of them I have been using them for work and home, and NOT just trying to use them for a month or so. I have setup them to my liking. Lately I do not want to loose too much time with configuring all sorts of small things... so I went with Gnome3 and KDE5, the winner was KDE5 because of it stability, Gnome3 is much more simple but even with i7 and 16GB of ram + integrated graphics if running for weeks it just turns sluggish, KDE5 just does not.
I do not count I3wm and Awesome and stuff like that here because those are not desktop environments but window managers. There is one more thing .. I am all for growing the Linux community ... with i3wm only you just not gonna get a lot of the Windows followers to use Linux -

In the past I have been experimenting with Delphi (long time ago), Java, C. If I really had to choose the favourite language ... probably Nix or Python, of course every language can be used for almost everything, but choosing the right language for the job is more important than sticking to one.

Lets investigate, I injected that character between characters of the word "abc":
- python
>>> len("abc") 5- nodejs
> "abc".length 5Also search engines...
try thishttps://www.google.com/search?q=Matejand thenhttps://www.google.com/search?q=Matej. First one is my name in plan, but the second has invisible characters embedded between every visible character. If Tildes is not filtering invisible characters from google link then the search results will be quite different.Here is my page that helps you inject this special character between every other character
Why would someone use this?
Well to be honest, this are just my findings. You can use this method to make words unsearchable in text, you can use it to obfuscate words that would be normally considered abusive and the automatic system would ban you from using it, but people would still see the word itself. Use case would probably be to mess with people. Let's say that you would like to write somewhere that has automatic abusive filter for words. Just write your dirty words into that static page I just shared and click Copy and then paste text to some portal that would normally automatically report/ban you for using abusive words. But I do not recommend this kind of behaviour for obvious reasons. -

For that I use Syncthing, someone could very well use Resilio, it is not opensource but has encrypted folders option, with Syncthing you would need to encrypt files on disk a bit differently.

I bought my first 3d printer just because of that, not having any special idea on what to print, this was just my shiny new toy. After a while of using it - printing stuff from thingiverse mostly - I expanded my hobby to design stuff in FreeCAD. Later I found out (again) the social aspect of creativity, people just like to find it in others specially if they can relate it to you, many do find a way. Also, its a good conversation topic (not just on the internet).
But back on the topic, look more objectively, what can you gain and what can you loose. If you have time for potentially time consuming hobby and you are or wish to be more technical person and have money to spend on a 3d printer, and then later on.. for material .... I suggest, go for it. But you have to take in consideration that this is hobby area, you will just not get a successful result every time, you will need to be patient and willing to tinker with slicing software and 3d printer itself.

NixOS (Linux) at job and as primary system for doing general stuff at home, I have been using it for a few years now, I love it because it just do not age by design - every other operating system that I know it will age and become slower by potentially every software you install. I am using Windows 10 for gaming, which I do not do much lately. Recently I am experimenting with Manjaro (Linux) which is the only distro in the top 5 of distrowatch that I could setup - the lazy way - on Lenovo MIIX 320, with actual battery indicator working, but that is probably because of higher versions of Linux kernel in the official repos.

Thank you very much for this thorough review, nobody ever does that. It was a negative surprise for me at the start, but when I read it all, it makes a lot of sense. I will fix some of the issues soon, but as far as the content goes... I do not like to change it much after it was published. I will defenetly remember this review when writing future blog posts.
PS: I know it is not an excuse but.... In my defence ... English is not my native language and I had some slight learning disabilities at the time I was learning it... allegedly :)

That might be the problem, if some part of the printer was bent (due to shipping I guess..?) it certainly can be the cause for adhesion issues, since you said that "was", I guess you resolved that issue to some degree, but since one layer is max 0.2 mm (for 0.4 mm nozzle) then the margin of error can be way higher on some parts of the build plate if its support is even slightly bent.
But as far as it goes for "normal" adhesion problems, you have few tricks
- I found out that if I raise the temperature of the extruder to the highest supported for the filament, it sticks better on the print plate
- heated print bed is also a good way to increase stickiness, I use 60C for PLA, but for trickier models (less surface on the print bed than higher up the model), a bit higher temperature for PLA can still be used
- you can use BuildTak like "permanent" plate that just tape over your plate (do not forget to readjust Z axis after installing it on your printer)
- you have many different types of tapes that you can stick on the build plate, but have never used them personally
- I personally use products like APrintaPro PrintaStick (for heated bed) or PrintaFix, this comes in liquid form that you apply on the printbed, be sure to clean it (I use warm and wet paper towel) after few prints and re-apply when necessary
- brim - just for enlarging first layer surface of the model [1]
- raft - I specially like this one, it raises the model itself and places few layers of material just underneath the model that way you have a firm surface and is a good starting point for printing, do not worry about separating the raft from the printed model, it usually goes off easily by hand [1]
Maybe I forgot some other type of adhesion trick, but please if someone has something to add ...
Brim and raft comparison: 1

Edit: oh yea and because of this guy @hook (he is always on track with open hardware and specially open software)
I have months of gaming at the time, and then my mood changes and right now my time is occupied by 3D printing and Rust... so I can't say much at the moment... Maybe more in a couple of months.
I play mostly single player games and when I finish them I usually do not replay them. As for the multiplayer games... I play now and then some co-op with my friends, like Satisfactory or the latest one was Star Rupture. I have to say that I lately dislike MMO games, but I fell in love with Warframe, especially I am fond of the gaming studio, DE and Warframe under the lead of Rebecca Ford is phenomenal. Really nice that in the year of 2026 not every gaming studio lives for all of your money.
