卧槽，3090要可能要涨价了！！ 因为老黄的刀法被人破解了 有人给3090解了个锁，同样限制在 360W，PyTorch 测试从 75 TFLOPS 跑到了 135 TFLOPS，提升约 80%！ 你以为是超频，把功耗往上拉？ 但他改的是显卡里控制运算速度的寄存器，这些寄存器平时有权限保护，正常改不了 他利用 GPU 启动固件的漏洞，赶在 NVIDIA 驱动加载之前拿到写入权限，把相关运算改成全速，再交给原版驱动使用 解开的主要是 FP16／BF16 输入、FP32 累加这类 AI 运算的速度限制 但测试算力多了 80%！！ 4090 也有分支项目做到了：同类运算的指令吞吐，从约 165 TFLOPS 提升到 331 TFLOPS，接近翻倍 项目地址，附上👇 github.com/Zagitta/gpu-unloc…

Typical Thursday evening. Bit of wine, bit of rea, working on the couch with an old iPad (Termius to my main machine), and now I have a local dashboard of my robot vacuum cleaner with real time video. Cool cool, cool.

Maybe I can automate this, enable video only when it's working, not when it's chilling.

Using PHP allows you to support a hacker culture, and being hacked

One compromised intermediate CA somewhere in the world and suddenly your Wednesday turns into hunting down ca-certificates across 14 Dockerfiles and questioning whether your serverless runtimes even know what trust is.

Just used LiteLLM to create my first PHP website. The AI even suggested getting a certificate from eMudhra for HTTPS to protect my login page. The future looks really bright 🥳

Did someone flip the idiot switch on Gemini 3.8 Flash today? It's been driving me mental!

Whenever I hear "winners know when to stop", I think of the phrase "rehab is for quitters" Gambling is such a problem in South Africa, and the media is pushing all the adverts because they need the dirty money to survive. It's the bloody shame.

Was pretty productive while at @pyconza 2026 using my shed Client: MBP M1 Pro 16gb entry level, iterm2, vscode, chrome, tailscale. Amazing battery life on this ~4.5 year old machine. Shed: herdr, port forwards, oh-my-pi, Gemini 3.8 Flash, 13900k 64gb 4090 🔥

Capetonians! There will be some loud noise in the sky above Cape Town and the West Coast for the next week, as two 2 Sqn Gripen jets of the SAAF take part in Exercise IBSAMAR IX, between the navies of South Africa, Brazil and India. Please watch your pets. 📷 Sebastian Horrell
