The Shady World of IP Leasing

https://acid.vegas/i/crowdkill.gif
The IPv4 address market has devolved into a wild sub-leasing economy where companies can choose their IP geolocation, scrub history, and rent residential IPs to make traffic appear legitimate. This infrastructure undermines the trust systems the internet was built on, making spam blacklists, geolocation databases, and IP reputation scoring unreliable.

Data is persisted in pre-allocated ring-buffer files per tier. Each tier file has a fixed maximum size — when it fills up, new data overwrites the oldest entries. This gives ...

What canceled my Go context?

https://blob.rednafi.com/static/images/home/cover.png
I’ve spent way more hours than I’d like to admit debugging context canceled and context deadline exceeded errors. These errors usually tell you that a context was canceled, but not exactly why. In a typical client-server scenario, the reason could be any of the following: Go 1.20 and 1.21 added cause-tracking functions to the context package that fix this, but there’s a subtlety with ...

Polar Factor Beyond Newton-Schulz – Fast Matrix Inverse Square Root

The Muon optimizer has found huge empirical success in machine learning. It’s essentially signSGD (or Lion by including momentum) for matrices. For the update, we need to approximate the sign function on the singular values of the momentum matrix to compute the polar factor. Goal: Given \(G\in \mathbb{R}^{m \times n}\) tall (\(m \ge n\)), compute the (column-)orthonormal polar factor For the ...
