This post uses a fancy data structure to construct a to_remove set, then iterates through it to remove these from the underlying header map. It appears the "remove_header" call is this one: https://docs.rs/pingora-

This post is really great! My biggest piece of advice to someone attempting to do the same is to browse the code via the online code browser, which has working cross referencing. (The codebase is so large it is not the sort of index you c

In the early ChromeOS days when they were thinking about which graphics stack to use, the quiet but definitive top manager said, if they picked X11, that he'd better not see any stipple on boot. It's such a funny comment that sta

I am using a hacky one I wrote myself. I looked at llm but it doesn't appear to have a mechanism for multi-shot prompting, where you provide both prompts and responses within your query. (Ref https://platform.openai.com&#x2

In case anyone else wasn't quite following this, I think the idea is e^x = e^(a+b+c+d) (where abcd are the bytes of x) = e^a * e^b * e^d * e*d and then you make a lookup table for each of those e^a, e^b values. (I fudged "a"

I am happy to answer basic questions, but it's been a long time so I would probably look at the patents myself to remember how anything works.

I was on the team too, with less impact than the names you mentioned. The team filed a number of patents that describe parts of how it worked. You can query a patent search engine with terms like [baker synonyms]. Looking now I think Ste

Does this mean they library can also "give up" their licenses once a book becomes less popular? (This is still worse than the system for physical books, but at least it lets them dial back the rent over time.)

Wine has a similar problem around needing to reserve the lower 32 bit address space for 32-bit executables. I bookmarked their Mac workaround around here: https://github.com/wine-mirror/wine/blob/b2a099b3ceec6

FWIW the sandbox-disabling bit in xz was in CMake logic, not autoconf. (Or at least the obvious one is in the CMake part; maybe the autoconf is separately backdoored.) https://git.tukaani.org/?p=xz.git;a=commitdiff;h=328c52
