Somebody made a native macOS client for this $60 power supply that I randomly chose on amazon. I added a cli to it, which makes it so amazing for scriptable experiments holy shit
🔥Have you ever seen a power supply THIS SMALL? Meet DP100 — the pocket-sized bench power supply that packs a punch! 💥#Alientek #powersupply #dp100

Took a minute to write a few words about security & safety as someone who lived through it all at OpenAI. I hope my thoughts help someone out there.

It's so crazy to see the face behind the voice I've been listening to for like 15 years
Some NPR podcasts started getting mysterious comments on Spotify. They made no sense to the staff reading them – until someone from a younger generation cracked the code. Hear the story: link.podtrac.com/phns92ui

I've just (re)written TaskExplorer Think Process Monitor but for macOS, open source, & much more powerful 💪🏽 Highlights: • CLI + JSON export • On-device AI assistant • Code signing + VirusTotal context • Live process/file/dylib/network activity objective-see.com/products/t…

The game hacking to security professional pipeline is very real. Get your kids into Minecraft hacks early!
Love these stories. 20 years ago I encountered ArtMoney for the first time, 18 years ago I copied a C# aimbot from patrickssj6(?), all the way to now… Game hacking, especially through the growth and advancement of modern tech, will teach you so many things.

This is about 70-80 tps, GPT 5.6 Sol is benchmarked at 40-50 tps on OpenRouter, yet Sol feels so much speedier. Why?
Happily running Deepseek with unlimited tokens in OMP on 2 DGX Sparks. Yesterday I was explaining to someone about local ai and the power you have with it. He was so intrigued that you can run agents and workflows non stop and not pay anyone. That person was related to my boss. We will see what we build on prem.

I'd like to introduce Kuna, a new Rust-based decompiler that explores a highly experimental direction: self-refining decompiler development and usage. Or: a decompiler constantly improved by agents, made for agents. Kuna rivals the best in structuring now. Let's talk about it.1/

one person is 10x'ing their output with Claude while the rest of the org is busy dealing with the resulting mess
I talk to engineers at other companies every day and hear the same thing: one person is 10x'ing their output with Claude but the rest of the org hasn't caught up. Watching teams adopt AI, I keep seeing the same 4 steps. I mapped them out here: Steps of AI Adoption claude.ai/code/artifact/bfdf…

This is the type of malware game hackers build to bypass kernel anti-cheat. The same techniques can be used by malware authors to evade EDRs. A UEFI bootkit that injects into Microsoft's own Hyper-V at ring -1 before the OS even loads (easier than building a custom hypervisor from scratch). Four phase bootloader. Hypervisor VM-exit interception. EPT page shadowing. MSR virtualization. EFI memory map ghosting. TPM measurement spoofing. Reads like malware. Because it is. Videos and full technical breakdown in the link. Author: gsmll.github.io/hypervenom/w… #ReverseEngineering #Malware #AntiCheat
While gamers debate kernel anti-cheat, ring-1[.]io was shipping a Themida-protected UEFI bootkit that injects into Hyper-V, manipulates EPT entries, clones game page tables, and hides memory contents below the OS entirely. After partially deobfuscating their binaries and recovering critical functions, this is what was inside. Bungie and Ubisoft sued them. They found $12 million in Bitcoin and kept going. This is what kernel anti-cheat is actually fighting. back.engineering/blog/04/02/… Authors: @BackEngineerLab #AntiCheat #Malware #InfoSec

This has been the best intro book to electronics I’ve encountered so far. I love it so much! I just wrapped up Part 1, which introduces the necessary foundational concepts and math in easy to grasp prose. Things are derived from first principles with no unreasonable logical leaps

Sometimes I get a stark reminder like this, that my twitter feed is a bubble. People absolutely losing their minds in the comments without understanding what Riot is doing
congrats to the owners of a brand new $6k paperweight

I’ve been keeping a secret for 5 years… For the first time, I’ll reveal the hidden 5th USB port on the original Xbox and how @MakeMHz spent the last year making the impossible possible with over 250,000 software patches. 🧵

Twitter replies seem to have become exclusively these 2 LLM patterns and its so fucking annoying: - Restates exactly what the post said in different words - "Its not just X, it's Y!" Its exhausting. Who wants this?

PlayStation is hiring for a mid level software engineering role on our Audio Team. Really interesting embedded development work on audio processors if you or someone you know is a skilled C/C++ developer! Job Description below

Since my whole timeline is full of people swooning about @dark1x claim that getting from one point of Crimson Desert’s map to another took a whopping 4 hours, let me share what’s going through my mind: I’ve been doing Level Design for 17 years now - I designed most of the levels / world for the Ori games and I’m still supervising LD on Wicked, so I think I can share some valuable insight. I always find it a bit worrying when everyone gets excited about ‘oh my god, they crafted an insanely huge world!’. In fact, I have basically the exact opposite reaction, which is more like: ‘Oh no, they started with a huge terrain, I hope they had an army of level designers to actually create a meaningful world instead of just a procedurally crafted, empty husk.’ I know how difficult it is to design good levels and how much time it takes us to build ours - so just hearing that, I already know that there’s likely not going to be a lot of actual good level design in Crimson Desert. And I actually don’t want to sound too disparaging or ruin anyone’s fun because Crimson Desert certainly looks insane and I can’t wait to play it myself either, but I also know how important and how underrated good level and world design is for a title and what the effect is if you have to OK huge, but empty worlds. I’d say at this point even some of the best studios in the world weren’t able to crack that nut. Even Nintendo struggled for a long time with the world size of Breath of the Wild and ultimately they had to put hundreds of devs on it to fill it up with content, but even their content then mostly consisted of ‘oh, here’s another Korok Seed!’ and other such lukewarm experiences. Since procedural level generation produces pretty crappy results and since we don’t have AI yet that can actually create well designed levels, the only way out of feeling like being in an empty world is to make every inch interactive. Minecraft did that and it was quite genius - but I doubt that’s what CD is going for. I understand the allure of ‘they created an entire universe!’, but be careful what you wish for: In Gaming Worlds, huge usually also means extremely shallow.

The worst thing about dealing with C (and C++ to an extent) code is understanding and debugging macros that you didn't write. Here are a couple ways of how to deal with them!

I dunno if it's because I'm old now, but every time I see "It's X times bigger than Y!!!" I get immediate dread bro I just want a good story I can finish after work, but I'm happy there's a lot to see
