Yes! Finally!
Screenshot of Bluesky's announcement for their new "Saved Posts" feature. On top, an example post from an account named Jerry Chen being saved for illustration purposes which reads "inventing a saturday that immediately follows mondays". Below, a caption announcing the new feature "Saved Posts. Finally! Keep track of posts that matter to you. Save them to revisit anytime".

Screenshot from a comment posted on the Stack Overflow question: "This is actually very interesting, not realizing that gcc treats asm blocks without outputs as volatile was a huge gap in my knowledge. – jleahy, Commented Jan 24, 2013 at 9:59"

Now this is true UNIX porn (on MAME because I'm not buying a SGI workstation lol)

A mi que haya 4x más ancho de banda de memoria me gusta, 25 GB/s era sencillamente ridículo en los tiempos que corren.

Detalle tonto que me hace gracia: la PS2 tiene casi *el doble* de ancho de banda que la Switch

Quarter wave LUT is done, time to take a break and document it :)

Another rather nice image... Of course, those artifacts shouldn't be there, but for the purposes of taking this picture I'm glad they are :D

Got Phase Modulation synthesis working on my FPGA! I could play a very trippy audio, but instead I'm using the following FFT to mark this milestone.

I have the pieces to also do PSG, playing PCM samples and mixing signals together, probably the 3 pillars of whatever audio HW I put into my project.

Dreaming about the future...

A screenshot of some terminal output demonstrating C's upcoming defer feature using GCC extensions: $ cat defer.h #define __DEFER__(F, V) \ auto void F(int*); \ [[gnu::cleanup(F)]] int V; \ auto void F(int*) #define defer __DEFER(__COUNTER__) #define __DEFER(N) __DEFER_(N) #define __DEFER_(N) __DEFER__(__DEFER_FUNCTION_ ## N, __DEFER_VARIABLE_ ## N) $ cat main.c #include <stdio.h> #include "defer.h" void foo(void) { defer { printf("Deferred!\n"); }; printf("Normal!\n"); } int main(void) { foo(); return 0; } $ ./main Normal! Deferred! $

Although IMO this is the peak storage format (the physical enclosure). Small enough for modern tastes, but big enough to remain a manipulable object (unlike those fiddly microSD cards we have now).

Actually, the fact it's as wide and a bit larger than a thumb may be the reason why I feel like that

Not the same style nor audience, but this is what tingles my brain the right way

Made a few other ASCII comments. I'm not sure how useful they will really be, but they are sure a joy to make :D

My setup is officially complete!
A quite packed setup including a 4K monitor (left), a 1080p BenQ Zowie XL2546K display (center, the main one), a Sony PVM 9045QM CRT (squished below those two) and a Sony CPD-2000ES CRT (right). The main screen sits on top of a Thomson VPH 7090 multistandard VCR alongside an Xbox Series X controller and a PS1 (+ its DualShock controller). On the desk, there is a Sony Walkman WM-D6C, a Nuphy Air75 keyboard, a Logitech G502 Lightspeed mouse and Sony PS1 Mouse (connected to an FPGA out of sight). Standing against the right wall, there is a Nektar Impact LX81+ MIDI keyboard, as well as a few other uninteresting things. Finally, a few uninteresting things: a blue glass, a cup with some pens and pencils inside and a can of Coke I have yet to drink :)

Cannot believe this guy is sitting at 27 followers here, so I feel obliged to spread the word: give @flipacholas.bsky.social a follow. His analysis have been a source of information, inspiration and motivation during my computer architecture journey.

My pet project right now is making the perfect not-so-retro machine out of a Thinkpad W530.

Thoughts so far?
A Windows XP installation with a black-and-green Evangelion wallpaper (EVA-01) and the Royale Noir theme. No windows open, so just the taskbar and the icons are visible. The icons on the desktop are: eMule, HxD, Firefox, Notepad++, Paint.NET, PuTTY, qBitTorrent, blender, HyperCam 2 and WinRAR (and the Recycle Bin on the opposite side). A Windows 7 installation with a Shadow (from Sonic) wallpaper. No windows open, so just the taskbar and the icons are visible. The icons on the desktop are: eMule, HxD, Firefox, Notepad++, Paint.NET, PuTTY, qBitTorrent, blender, HyperCam 2 and WinRAR (and the Recycle Bin and a reboot to Windows XP button on the opposite side).

@macleouc.bsky.social conservas alguna copia de los ISOs de LinEx que se distribuyeron? He probado a buscar en archive.org pero solo encuentro la 2006 RC2 y otra que creo que es la 3.0. Me gustaría poder encontrar otras como la 3.0, 2004, 2010, 2011, etc

Tengo varios MD5s pero casi ningún ISO...

I'm silent here, but I keep working in the shadows.

The most notable addition? PCM audio support. Turns out ΣΔ is super easy to code!

Also: slightly increased performance & Fmax, mandatory M+U mode CSRs implemented, ecall/ebreak/interrupts...

Also progressing through @pikuma.com's 3D course :)

@tsoding.bsky.social looks like you're being presented as evidence to back up a proposal on page 2 of www.open-std.org/jtc1/sc22/wg...
