Saving A Vintage High-Voltage Power Supply From The Scrap Heap

A Fluke Model 407 high-voltage power supply gets rescued from the scrap heap and diagnosed on video. Mr Carlson powers it up safely using an isolated transformer and a current-limited variac, avoiding the risk of full power on old components. The vacuum-tube-and-circuit-board unit shows no visible damage but its output misbehaves. Using the original schematics, he traces the fault to a single faulty capacitor in the feedback loop that keeps output voltage constant.

Linux 7.4-rc2 Released With FAT32 Optimization, AMDGPU HDMI 2.2 Improvement

Linus Torvalds released Linux 7.4-rc2, calling it a big rc2 following the largest ever rc1. The release includes a notable FAT32 performance improvement, especially for synchronous mounts, AMDGPU driver fixes for HDMI 2.2 FRL, and numerous fixes for long-standing core memory management bugs. Torvalds noted the diffstat looks benign and is largely driven by automated coccinelle script updates that add noise, and that AI-generated fixes and bug reports continue to pour in. He said Alexei claims fixes on the bpf side are now coming in faster than new reports. Linux 7.4 is aiming for a stable release around the end of December.

The PlayStation 3 briefly made buying a console a way to buy a Linux computer

It was a little too good at what it did, though.

I changed one llama.cpp flag, and my 8GB laptop GPU now runs a 35B model faster than I can read

Một lập trình viên đã tìm ra cách chạy model Llama 35B trên laptop GPU chỉ 8GB VRAM với tốc độ đáng kinh ngạc. Nguyên nhân kỹ thuật nằm ở việc chỉnh sửa cờ n_gpu_layers trong llama.cpp, cho phép tận dụng hiệu quả bộ nhớ VRAM thay vì để nó trở thành điểm nghẽn. Hệ quả là model 35B parameters chạy nhanh đến mức người dùng không kịp theo dõi, vượt xa các kỳ vọng ban đầu về giới hạn phần cứng. Điều đáng học hỏi là đôi khi vấn đề không nằm ở cấu hình phần cứng mà ở cách tối ưu hóa phần mềm để khai thác tiềm năng thực sự của hardware.

Bài viết tiết lộ cách tối ưu hóa một cờ trong llama.cpp để chạy mô hình 35B trên GPU 8GB nhanh hơn tốc độ đọc của bạn.
