I have a small change in the project client said.
"Small change" turned out to be basically entire fucking rewrite.
Luckily it was just a tiny android app and was done in 2 hours.
I wanted to find work as C programmer in Slovakia but as it seems nobody in Slovakia needs C programmers.
Hell i would even take work outside slovakia if i could work from home.

I will change it once somebody notices it.

My internet was down last night. Last time my ++ was at 37K.
I looked today and its 40.2K thank you to all the people who did this.
You are truly the best dev community there is.
Huge thanks to all of you again from Haxk20

If you havent noticed Me (Haxk20) and C0D4 are having a fight over the ++ count.
I know that you are a smart person and you know what to do now.

Ending AMD E3.
Ryzen 9 3950X:
16 cores
32 threads
4.7 Ghz
105W
For 749$ (Intel CPU is like 1,5K$ i think)

Radeon RX 5750XT
RTX2070 + ~10 fps for 459$
Or the 50 aniversary for 499$

Not bad at all.

Question.
What method do you use to read or understand someone else code ?

Fucking hell. I spent weeks. Fucking weeks solving my Z banding issue on 3D printer (Thats when layers dont allign on horizontal side of things as they should).
Tried a hell ton lot of shit like changing the lead screw, New Z nut holder, Coupler. Just lot of shit.
But no fix.
Until i just noticed that it all began with 1 fucking upgrade i did and then i didnt print for few weeks so i forgot about it. I knew the part wasnt sticking to the bed good but i rolled with it. NOPE NOT A GOOD IDEA NOW.
But back them it was OK.
Seems like 1 wheel isnt rolling with them thigtly and juts fucks up everything.
Well now this will be a week of fixing the shit out of it.

It was a nice day when we were coding with friends and working on an arduino project to monitor the temperature and all that shit.
But all the values coming out were just few numbers off.
We coudlnt figure out why.
We spent weeks trying to figure it out.
Until a friend gave up and just commited "Fix the fucking bug"
And all it did was value - 5.
We never solved it properly but it works.
The project is long dead and all parts were used in different project but the memory is still with us and we always joke about it when we have similar bug.

I must confess. Im not running drm-next-5.3-wip AMDGPU branch.
Im running the latest git commit on mainline but not the latest AMD patches. Well yes i was busy.

And i must say im getting tired of this joke. Yes im running all the latest shit but its not so crazy. Well at least not for me.

This is what Haxk20 desktop looks like. Full view of every fucking core and memory in system. Temperature and all wrapped in nice and stylish GNOME 3.32.2 + master patches.

I dont remember exactly as it was long time ago but i think it was GUI app using SDL. It was calculator.

Mesa devs can fix issues kind of fast. WOW.
20:20
Reported a bug
21:27 bug fixed.

GNOME devs can take a good example.
No offense to GNOME devs. They are doing great job its just that it takes them 1 week to even ask for logs.

I compile mesa from git i said.
Its easy they said.
I compile LLVM from git i said.
Thats easy too they sad.
Too easy ? i said
Yeah they said.
I compile kernel on daily basis from git and thats my only kernel on my daily machine, I compile Wayland, xf86-video-amgpu, gnome-shell, mutter, libdrm, gtk4 and Xorg (IDK why even tho i dont use it) at least twice a week i said.
You are crazy we fucking give up they said.

I love Phoronix and all but dammit some of the news are few days old. Yeah i get that its one guy and all but i think few of us should get their brains to work and maybe create something similar.
What do you think guys ?
BTW this is Haxk20.

Haxk20 here.
You probably dont know if you dont know me but i have created that stupid school project.
Now that i finally released source code for it. (Finally took me fucking time)
Im starting to polish it up a little bit and also make the code just better.
I probably havent explained what it is even.
Well its Arduino Based P2P network using LoRa as the main communication device and Bluetooth so you can use Smartphone to send data to it.
Really simple indeed but really powerful.
The project got turned down in competition as it didnt have "modules" they said. They wanted to make it device you could use in home to boil your coffee or some shit. Like IoT isnt enough now.
Kind of glad that it didnt win because that idea was horrible.
OK now thats out of the way.
If you want to contribute to it you can do so here: https://gitlab.com/Haxk20/...
Schematics, PCB design and boards used will be on there in few days. School is taking some time so i dont have much time to do it now.
Oh yeah and it also needs better name but well im terrible at naming things as you can see by the name of that project.

Not a rant.
I just heard that im not as active as i used to be.
So here. Empty Rant. Enjoy.

//Haxk20 here (Just to avoid those stupid i knew it was you comments, Dont you fucking dare post it in there now that i said dont do it. Dont be an asshole)
Arch repos finally have GCC 9.1
Its time to test this.
There is only one test worth it tho.
No Not compile some stupid small project.
No
We must go big or go home.
We will build kernel.
Right after that Ressurection Remix.
And to finish it off Mesa.
Time to beat on Kernel side is 45 minutes.
On RR side 3 hours
And mesa well 3 minutes.
But since its 11 fucking PM already i will leave the tests until tomorrow.
I wake up really early tomorrow.

Haxk20 Here.
I finally released source for the project i have been working on in school.
Its P2P system with LoRa based on Arduino.
https://gitlab.com/Haxk20/...

Also NEWS:
I will slowly but surely start changing names over multiple sites from Haxk20 to DarkNeutrino as its much much more easy to pronouce. devRant will most likely stay as Haxk20 since most people here know me with that name but when you see DarkNeutrino somewhere on internet. Its me.

Metro Last Light i love you you know that but dammit you can be one bitch.
You just love that RAM do you ?
Yeahhhhhh you do.
10Gb just like that.
2gb minimum and you eat 5x that on loading screen.
But damn before i upgraded my RAM i had 20 fps on max graphics.
Now i have 60fps. MUHAHAHAHA
Oh i love this game.

Fucking hell. Webrenderer in Firefox is broken on latest mesa. Fuck. Well time to report a bug.

Its here again that type of year. I feel shitty and my body hurts like hell.
Yes. Yes Haxk20 is fucking sick again.
Packages arrived today. Yayyy. Well body says no. Can't even get myself from bed. It hurts.
Fuuuuuuuuuuuuuuuuuuuuuuuuuuck

I just finished watching Lucifer Season 4 and oh boy is this amazing season.
Netflix outdid themselfs. WOW
Really good job Netflix.
Now i hope i dont have to wait 2 years for season 5.

Guys Haxk20 here.
I need one thing from you who are running Linux and AMD GPU.
I need you to just send me dmesg. (Pastebin or similar site)
I need to see what GART size your GPU is using.
Thank you <3

Google just annouced Dark Mode in Android Q.
Well it took you 6 years of fucking telling you but hey you added it finally.

The moment i started Android Porting.
The tons of messages i got on XDA from random people.
Oh fucking hell
But one message was like WTF ?
Not exactly the message but it has the same point.

Hey Bro, I installer your room and it work but when i turned my phone of it didnt turn back on. The small buttn on side doesnt work to turn it on.

Then he posted the same message to thread since i dont respond to PMs.
Some user helped him and what was the issue ?
HIS FUCKING PHONE BATTERY WAS DEAD
He just had to charge it. FFS

Fuck fuck fuck.
I'm waiting for 1 fucking package to arrive so I can finally finish my dual z rod upgrade on my printer.
And I can't print anything until I finish that upgrade because one side of X axis is lower then the other one and that results in horrible prints.
I mean horrible prints as one side of the print has more plastic then the other one and starts to lift slightly.
What's the package I'm waiting for ? 2 GT2 teeth bearing.
I could possibly print them but since the quality is horrible they wouldn't fit.
Fuck.

Fuck. The moment you order something and it comes to your door but you dont know WTF it is because you ordered so much stuff.
Also fuck cause i didnt look at the picture and there were 2 things in 1 package and i requested 2. Well now i have 4. 5$ byeeeeee

So. This is Haxk20 Rant about EDID.
I again have been trying to get Freesync working on Linux but this time without some huge hacks around EDID etc.
So i got my normal EDID file and instead of coping the data from it to freesync EDID i got CEA block from the freesync one and hex edited the normal one.
Fail.
Checksum failed.
After learning how checksum is calculated i found a python script to do just the thing.
Fail
CEA block checksum fail
Why the fuck 2 checksums.
Well after learning how that is calculated i modified the python script and run it.
Pasted the checksum in and what the fuck ? It actually loaded the file without giving error.
Now only thing that remains is to load it in system.

Got lappy back. Added Dual Channel RAM. Build everything from source since i was 1 month behind in commits.
Found out today that i can finally manage Watts limit of my dGPU (RX560X) and i can finally Overclock it too.
Ohhh boyyyyy im going to have fun.

2 things i learned about dual channel.
Seems like Ryzen doesnt get some extra boost with dual channel but GNOME is much smoother with it.
But dang system load is reduced a lot.
Before it was 1000% when compiling
Now its 80-110% and it compiles it even faster.
Cool.
And holy shit 8Gb RAM is not an option when compiling or building android and other shit.
I would always run out.
Now i can watch YT and still have 50% of RAM free. HAHA
