I have a 24 hours hackathon tomorrow (25 hours actually because of the time change).
I want to learn and create an app and I opted for xamarin as a development platform. Problem was: I didn't have enough space in my windows partition (it's a ~40Gb partition in a 128Gb ssd) so, as I am not using Ubuntu that much I simply deleted its partitions from Windows and installed visual studio with xamarin. I played a bit with it, everything was working fine, I switched it off and I was feeling great for my wonderful problem solving abilities and I was ready to go to bed to have a nice 10 hours sleep before the big event. I was about to sleep when I realised it was my cousin's birthday and I hadn't said "happy birthday" so I switch my computer back on and there I realised how much I had fucked up.
The grub wasn't working anymore and I couldn't boot.
I've just spent the last 3 or 4 hours trying to figure out how to make my computer boot normally using my housemates' laptops to create bootable USBs for Windows and Ubuntu
Thanks to some random commands in the trial version of Ubuntu I managed to disinstall the grub and make windows start but thanks to my experimentations while trying to fix the problem I am now waiting for visual studio + xamarin (~35Gb) to download and install again.
Tomorrow's gonna be great

So, I decided over the weekend that I would move my entire dev environment to Linux. No Windows on the laptop and only as a backup boot system for my home PC. I wanted to wean myself off of Linux as only being a VM and move to the full blown desktop.

I can only describe my experience to that of having your first kid: lot's of crying and joy at the same time.

Things I've learned:
1. The install is amazingly painless. Wi-Fi and Bluetooth work straight out of the box no configuring needed.
2. OH MY GOD THE CUSTOMIZATION. Rocking Arc Dark theme on Gnome3 = EVERYTHING IS
ALWAYS DARK MICROSOFT WHY IS THIS NOT A THING.
3. Getting Java servlets to work has been hell. I gave up trying to get them to work in eclipse and moved over to IntelliJ. More trial and error before I can figure out why tomcat won't fucking work in eclipse but it's fine in IntelliJ.
4. The UI and overall work flow has been improved after getting past the learning curve. Gnome3 is way better from when I tried it out 4 years ago.
5. Vim has a steep learning curve but I am starting to understand the net benefits of it. It'll probably be a solid month before I get good with it.
6. Loosing Microsoft Office has been a little bit of a challenge but their suite is online so....meh. I do miss Visual Studio though, and am still looking for an adequate replacement for C++ and C# development.

Overall it's been a challenge but I think it's been a net gain. Now if only I could get the whole sys-admin team to use it. ;)

I hate the fucking Spring WebFlux and the goddamn Project Reactor on which it depends!
Even debugging a simple CRUD microservice with simple business logic is such a pain in the ass, exception handling has a lot of "magic" implicit stuff which makes me waste hours in fucking trial & error and I have to use very little breakpoints because if a request is paused for more than few seconds it gets terminated.
I love functional programming but why shove it in fucking Java making me waste 90% of my time in trying to guessing what the fucking framework is doing, why not just use Scala which runs in the JVM? We don't even need compatibility with legacy code since it's a greenfield project!

And before you ask yes, I read a fucking book about Project Reactor and Java reactive programming and a lot of docs on Spring, Spring Boot and Spring Web Flux.
