I also have an ES47 (running Linux)! Would you send me an email to my username at gmail? I've been working on a remote management tool for the ES47 that allows controlling the fan speeds that you might be interested in.

I think they're super uncommon in the west. I think they're also super useless, to be honest. Incredibly slow. Linux support continued to degrade the entire time I owned mine. The keyboard and display are far too small to be usabl

I've loaded the PROM in Ghidra. The ability to decompile to C is great. I looked at some particular parts of the PROM that took a while to understand to see if I could have understood them quicker with Ghidra. In particular, the part o

Thanks! I'll give Ghidra a try!

Yes, I submitted it as "PROM". I have no idea why it has been changed.

Yes, it's still used in the Intel 3D drivers in Mesa (at least).

On an Intel GPU, you can check the 'Video' percentage in `sudo intel_gpu_top` (from the igt-gpu-tools package) while playing a video.

That's right. "Software decoding" means the decoding algorithms run on the CPU. (As opposed to "hardware decoding" which typically means the work is done by some fixed-function video units on e.g. a GPU)

Are you familiar with source-based distributions? I'm not rebuilding specifically for this one potential optimization.

by mattst88 3y ago
I actually do. I just said -march=tigerlake to make it clear what CPU family the compiler was targeting.
17.
by mattst88 3y ago
Right. Since I'm using Gentoo and compiling my whole system with `-march=tigerlake`, the compiler is free to use AVX-512. My question is just... does it? (And does it use AVX-512 profitably?)

I am a happy owner of a Tigerlake (Intel 11th Gen) Framework laptop. I've considered upgrading to a 12th or 13th Gen motherboard, and while I have no doubt they'd be great for me as a Gentoo developer with the greatly increased co

I don't have enough details to debug, but something I discovered just the other day might be helpful if you're building the kernel. For kernel builds, you have to specify CC= after `make`, not before. E.g. `make -jX CC="dis

This is very interesting. I'm going to be excited to see what neat things can be done with it.

Signs a couple of different things: most notably they're signals from the catcher to the pitcher suggesting a pitch for him to throw, but also there can be signs from the dugout to a batter telling him to bunt, or to a runner on base t

Yeah, I remember when I got mine—I wasn't expecting anything, and I kinda wished they hadn't given me anything at all if they were going to just give $25. Felt pretty cheap.

Reportedly it's not just the CEO... - No merit salary increases or promotions - No more quarterly bonuses - No more employee recognition programs (e.g. no more $25 gift card for working at Intel for 5 years) - 401k match drops from 5%

dosdude1 is awesome. He replaced the BGA CPU in my iMac G4 with a 1.7 GHz MC7448 ( https://mattst88.com/computers/imacg4/ ) and made a video about the process: https://www.youtube.com/watch?v=SnpdLt4
