The ASUS Gaming Laptop ACPI Firmware Bug: A Deep Technical Investigation If You're Here, You Know The Pain You own a high-end ASUS ROG laptop perhaps a Strix, Scar, or Zephyrus. It's specifications are impressive: an RTX 30/40 series GPU, a top-tier Intel processor, and plenty of RAM. Yet, it stutters during basic tasks like watching a YouTube video, audio crackles and pops on Discord calls, the mouse cursor freezes for a split second, just long enough to be infuriating.

How many SPARCs is too many SPARCs?

How many SPARCs is too many SPARCs? Posted on 2025-08-20 Contents Background I was browsing /r/vintagecomputing, as you do, and I came across this post: Hi all. Back in the day I was a developer working exclusively on Solaris. About 25 years ago, for one reason and another I came into possession of about 30 assorted SPARC based workstations and a few other bits and bobs, network/SCSI cards, keyboards, mice, etc. I think there's also one UltraSPARC in there too. This stuff was well past its

The world has a running Rational R1000/400 computer again (2019)

news.ycombinator.com Unknown 2025-10-06 06:46:55

2019-12-11 SCSI command 0x0d seems to be explained now: Søren Roug has spotted SASI command 0x0d in the manual for the Xebec S1410 diskcontroller: It returns the length of burst errors corrected with ECC. That matches the CMD_CORRECTION Tollef found. Thanks everybody! 2019-12-08 About that 0x0d SCSI command... My good friend Tollef Fog Heen replied on twitter that this source file on github calls the command CMD_CORRECTION. That github repository contains a NeXT Station emulation. The

Classic 8×8-pixel B&W Mac patterns

news.ycombinator.com Unknown 2025-10-08 23:53:42

TL;DR: I made a website for the original classic Mac patterns I was working on something and thought it would be fun to use one of the classic Mac black-and-white patterns in the project. I'm talking about the original 8×8-pixel ones that were in the original Control Panel for setting the desktop background and in MacPaint as fill patterns. Screenshots via to Marcin's awesome interactive history I figured there'd must be clean, pixel-perfect GIFs or PNGs of them somewhere on the web. And perh

SIMD within a register: How I doubled hash table lookup performance

news.ycombinator.com Aleksey Maltsev 2025-12-20 14:41:34

While working on a Cuckoo Filter implementation in C#, I created an array-like structure for the underlying hash table. I chose an 8-bit fingerprint: it aligns nicely on a byte boundary and still keeps the false-positive rate around 3 %. The layout looked straightforward—just a byte array where the start of each bucket is calculated as bucketIdx * bucketSize . The size of each bucket is 4 slots, which is a solid choice for Cuckoo Filter. Bucket 0 3A 00 B7 F2 Bucket 1 4C 91 00 DE Bucket n AA 00
