It's actually not even 60. The FPS target is configurable in the settings and for some reason the default is 57.

Given the memory configuration it seems extremely unlikely that it's socketed. It's certainly not AM5.

The document editing portion just uses Collabora which is based on Libreoffice.

opencl — Fri, 06 Jun 2025 13:43:07 +0000

The Strix Halo GPU is roughly around RTX 4060 (laptop version) performance.

Phoronix just doesn't do much mobile dGPU testing in general to have any data to compare with there.

The best thing about Renpy is that the text rendering actually looks good, which is true of shockingly few VN engines even today.

Especially when you increase the window size or run fullscreen, most VN engines just render the whole game at a fixed resolution and upscale it up but Renpy makes the framebuffer match the window size and renders text at the full resolution.

It's been done before. Lots of 90s bootleg consoles used clones of the Famicom/NES chips, though they weren't particularly accurate clones. The Commodore 64 Direct-To-TV of all things had a custom ASIC made for it in 2004.

I think these days FPGAs have just gotten cheap enough that the economics of making custom chips doesn't make much sense for the volumes these kinds of products tend to sell.

Because nobody makes 24V power supplies for computers, they'd have to convince the whole industry to agree on new PSU standards.

The actual Car Thing runs Linux on an Amlogic S905D2 (quad Cortex A53) with 512MB RAM/4GB flash and an 800x480 screen. So you could do something similar with pretty much any random cheap ARM SBC.

opencl — Mon, 23 Sep 2024 20:49:54 +0000

The actual manuscript from Rayleigh [1] explains it better: the area is the entire area of the vessel the oil was placed in, and the thing actually being measured was how much oil was required for it cover the whole area.

I've heard people claim this but never seen any actual evidence of license violations.

Everything seems perfectly in order with both the Linux-based firmware on the X1C[0] and their slicer[1] which is a fork of Prusaslicer.

No die shots but the Wikipedia articles of all things on the MK61 and MK52 are surprisingly thorough including photos of the PCBs, schematics, and the External Links sections contain most of the interesting articles I'm aware of about these.

They're quite interesting and quirky machines, definitely HP-inspired but unique in a lot of ways. Especially the MK52 with the built in EEPROM (though other than the EEPROM and connector for an external ROM it is functionally identical to the MK61). They're also still readily available and cheap on eBay if you want to play with one.

Most of these couldn't move fast enough for aerodynamics to matter much. A Ford Model TT truck had a top speed of 15mph without a house attached to it.

New comment by opencl in "40 years later, a game for the ZX Spectrum will be again broadcast over FM radio"

opencl — Wed, 08 May 2024 15:41:04 +0000

The format is very simple, basically a square wave with different pulse widths for 1s and 0s [1]. Spectrum software was typically sold on audio cassettes and the radio broadcasts are the exact same format, typically people would record the broadcasts to cassette. The loader program in ROM just copies all the data from tape (or radio) into RAM so yes any game logic would be included in that.

opencl — Mon, 08 Jan 2024 19:38:43 +0000

OpenBSD out of the box is an extremely minimal setup compared to the default install of most Linux distros.

A lot of the security of the default install comes from minimizing the attack surface by having very few services running. So you do not need to be tech-savvy to make it secure, but you might need to be tech-savvy to turn it into a usable system for your use case.

They posted an article a while ago with a high level overview of how FF Sync encryption works, but the TL;DR is that the key for E2EE is derived from your account password.

This CR report is about the reliability of new cars over the first year of ownership. The correlation to how many issues there will be 10, 15, 20 years down the line is rather tenuous.

The "Red Baron" version was just from a company that sold freeware games and changed all the names presumably hoping that nobody would notice.
