GPU Mode, in collab with Core Automation, recently hosted an auto-research themed contest. The problem statement was toimplement batched square compact-Householder QR factorization aka QR decomposition. I placed 12th out of 183 participants, ending up with a 232x speedup over the baseline solution. This post is about how I got there. I will go through … Devamını oku
When the address of a nested function is taken, GCC creates at trampoline at run-time. This trampoline is placed on the stack, which means that the stack has to be executable. This is problematic because a non-executable stack is an important security feature. For some time now, GCC has the option to place the trampoline … Devamını oku
An interactive drumhead. Press Enter or Space to strike it at the marked point, and use the arrow keys to move that point. While drawing is switched on, drag with a pointer to trace a new outline. Every mode is a standing wave this outline permits, and no other. Tap anywhere: the modes with a … Devamını oku
We’ve been sharing more about how we work: building Amp with Amp,orbs, killing features, no pull requests. And the most common reaction isn’t about the AI workflows or whatever kind ofloopgraph engineering is flavor of the week. It’s this: Wait, you don’t use pull requests? You push to main? How? That’s not SOC 2 compliant. … Devamını oku
Even as thedigital components of so many life-critical systems have proven susceptible to cybersabotage—cars,medical devices, evenwater utilitiesandpower grids—the computer systems of airplanes have, thankfully, remained uniquely inaccessible to hackers. But one group of academic researchers has spent years testing a different, devious approach to aviation cybersecurity. Perhaps, they suggest, a plane could be hacked the … Devamını oku
Earlier this year Apple denied me access to App Store Connect after deciding that I matched someone on a U.S. government restricted-party list. Their explanation was fairly definitive: “The information you provided fully matches one or more restricted parties on the U.S. government consolidated screening list or another government’s sanctions list.” I replied with my … Devamını oku
Most SSH hardening guides stop at key-only auth andfail2ban. That helps, but if your machine has a public IP, port 22 is still open to the internet. Every automated scanner can probe it and get a response: the SSH version string, the banner, proof that something is listening. The log noise alone is annoying: even … Devamını oku
I’m tired boss. I’m tired of reviewing one, two, threethousandline PRs because some agent was able to “one shot the whole issue.” Small PRs were never asked for because they’re easier to write, it’s always been for the benefit of the reviewer. AI is such a boon to the industry, but it’s becoming such a … Devamını oku
I am often asked to explain my distaste for RISC-V and I often find myself explaining it piecewise. The reactions are often of the form “you just do not understand the brilliance of it all”, which is, of course, no argument at all. After being asked for the Nth time to explain, I decided to … Devamını oku
Today we’re excited to showcaseHEIR, the latest powerful tool added to our Private Computing Toolkit. HEIR is an open source compiler that unlocks cryptographically-secure private AI inference. As new benefits emerge with the growth of AI, balancing privacy and security is top of mind. Standard protections like end-to-end encryption present a trade-off: user-data can be … Devamını oku
