When it comes to information security headlines, a good rule of thumb is that claims about about widespread supply-chain sabotage are usually false.

Bypassing disk encryption on systems with automatic TPM2 unlock
(oddlama.org)
Have you setup automatic disk unlocking with TPM2 and systemd-cryptenroll or clevis? Then chances are high that your disk can be decrypted by an attacker who just has brief physical access to your machine - with some preparation, 10 minutes will suffice. In this article we will explore how TPM2 based disk decryption works, and understand why many setups are vulnerable to a kind of filesystem confusion attack.

Intel's Tofino P4 Software Is Now Open Source
(p4.org)
We are excited to usher in the dawn of a new era for the P4 programming language. For many years, the Tofino family of programmable Ethernet switches, powered by P4, has represented the cutting edge of network innovation. Tofino’s unprecedented levels of programmability have enabled organizations to shape their networks like never before. But there was always one limitation: the software driving this groundbreaking hardware remained closed source. Today, that changes.

The Game Boy Talk [video]
(media.ccc.de)
The 8-bit Game Boy was sold between 1989 and 2003, but its architecture more closely resembles machines from the early 1980s, like the Commodore 64 or the NES. This talk attempts to communicate "everything about the Game Boy" to the listener, including its internals and quirks, as well as the tricks that have been used by games and modern demos, reviving once more the spirit of times when programmers counted clock cycles and hardware limitations were seen as a challenge.

From ASCII to ASIC: Porting donut.c to a tiny slice of silicon
(a1k0n.net)
For many years after coming up with donut.c, I wondered in the back of my mind if it could be simplified somehow, like maybe there was a way to raytrace a donut with a small chunk of code. In October 2023, I tweeted a dumb random epiphany where I figured out another way to do it which requires no memory, no sines or cosines, no square roots, no divisions, and technically, not even any multiplications.

Mac Mini G4 – The best « classic » Macintosh for retro-gaming?
(xtof.info)
Although my first computer was an Apple II, I never was a Macintosh user, as my family switched afterwards to the PC. But reading the magazines made me familiar with this family of computers and I wanted to add a pre-OSX Macintosh to my collection for some time. The only things that refrained me were that most Macs use esoteric plugs and that I did not have the space.

Plenty of computer monitors made debuts at the Consumer Electronics Show (CES) in Las Vegas this year, but many of the updates at this year's event were pretty minor. Many could have easily been a part of 2024's show.

Getting an all-optical AI to handle non-linear math

A team of MIT researchers figured that if you had a chip that could process photons directly, you could skip the entire digitization step and perform calculations with the photons themselves. It has the potential to be mind-bogglingly faster.
