Please, everyone using #make in the install scripts of their projects: Use make -j $(nproc) instead of just make for the #build process.
It forces make to use all available #CPU cores, speeding up the process a lot. It does run the CPU to 100% on all cores, but the time saved makes it well worth it.
As much as I like #Armbian, the fact that it does not start the PWM fan of my #nvidia Jetson Nano device is a serious problem during the summer. 🥵
My device already overheated and shut down today. Only workaround I found so far was to throttle #CPU at 50% max speed, which for now keeps the system stable at below 60°C, but is far from ideal.
Anyone who knows how to get the #PWM Fan working, please talk to me 🙂
A neat "book" i came across courtesy of @itsfoss.
"Putting the 'YOU' in CPU" explains how a CPU works, how computers run programs, and the basics of these wonderful devices that have taken over our life, in simple (ish) terms.
For anyone that wants to know HOW computers do what they do, this is a great place to start, and it's free, readable on the website, on GitHub, or as a downloaded PDF.
Found a picture of the incomplete TTL homebrew CPU I was working on several years ago. Haven't finished it the program counter and instruction decoder worked
Nvidia just announced a 2nd-gen variant of Grace Hopper CPU-GPU combo package for monster big AI training tasks. Hopper GPU gets faster new HBM3e, 141GB vs 80GB of HBM3 on 1st-gen. Grace CPU has 144 Arm Neoverse cores. Systems will ship in Q2 2024. #Nvidia#AI#Siggraph#GPU#CPU
My phone is now 6 years old. It still has all the performance I need and probably will for years to come. But it hasn't received an update for years due to capitalism. Therefore, for security reasons, I should have replaced it years ago (can't afford to though). There should be laws against this kind of fabricated bs obsolescence. #smartphones#capitalism#obsolescence
Seems that Intel's Performance + Efficiency core CPUs work just fine on newer Linux kernels (6.1.38 in this case). I was a bit uncertain how it would turn out.
I'm currently running video encoding on 8 cores, and it picked the P-cores. Those are the even numbered cores from 0 to 15 (the odd numbered are the hyperthreaded P-cores). The E-cores are numbered 16 to 23.
My usual amount of #openssl hate :blobcat_amused:
Few weeks ago I had spam wave on my mail from my Zabbix, about high #cpu load. Firstly I shrugged it off as it is low resources VPS with too many services, I kind of expected this. One day I checked it for curiosity and found it was mainly openssl #ocsp process eating my resources. I restarted service, everything looked good.
Some time passed, yesterday I was doing random things on my server. Checked #htop without any particular reason and saw it again. This time I was more irritated and disabled service completely. I didn't use it on "production" anyway.
I am not sure if it was normal. Maybe openssl docs tell the truth and it is not a good way to run it long-term?
BTW what the hell am I doing with my life?!
WOOOO HOOOOO! I have completed my first real #upgrade to my self built #pc and I did it ALL BY MYSELF!!!
Upgraded the #ram and the #CPU. It was a bit of a nail bitter but I got it done :partyparrot:
Fun fact: When I initially built my pc, I put on waaaaay too much thermal paste. I think I spent 5 mins removing all that paste before I installed the new CPU :ageblobcat:
CPUlator: A web-based CPU simulator where you can watch memory and registers change as you run the program through the debugger. In the spirit of SPIM, for those of you who used that.
Thought: Is an SOC more secure than using descents components?
In the sense that: It’s possible to freeze the RAM chips of a running system to later extract the disk encryption key from it. I’m assuming this doesn’t work on SOCs?
Either way, a transparent #Encryption & integrity checking of #RAM done with the #SoC / #CPU / #Memory#Controller is something that is propably the only way to make said attacks unfeasible...
AFAIK only some #GameConsoles and #Military Hardware does that and I don't have reliable data on those either...
