Luke Champine writes hi, a personal blog at lukechampine.com about programming and security. Since 2016, 5 different Hacker News readers have linked it 15 times, most often “Hacking Go Maps for Fun and Profit”. No feed was found, so read it on the site itself.
Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for the Goldilocks tool, which finds places with weather like a given city, and for writing on Sia's client-side encryption. Comments say little about the writing itself.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
Just use this tool: https://lukechampine.com/goldilocks/ (Posted to HN two months ago and very helpful convincing my wife that there’s only a couple places in the US with weather like San Diego)

HN discussionEncryption on Sia happens on the client-side, so the host has no guarantee that the file is actually encrypted.[1] For encrypted data, I think it will be similar to the situation with other storage providers. If law enforcement searches your computer and discovers that you've uploaded illegal content in encrypted form to S3/GCS/Mega (especially Mega because they make it so easy to upload client-side encrypted data),…

HN discussionLLMs can be deterministic too! People just don't bother because the applications of this aren't widely known yet. See https://lukechampine.com/repligraphs

HN discussion> Yes, you can access them; but I don't believe you can link them. I think you can if you use debugfs. I wrote a post here about recovering a running binary after deleting the file on disk: http://lukechampine.com/recoverbin.html

HN discussionHere's a simple example: Say that your server has an admin login that simply compares the submitted password to "thisistherootpassword", one byte at a time. The attacker starts by trying "a","b","c", etc. and measuring the time it takes for the server to respond. When they get to "t", the server takes slightly longer, so they start trying "ta","tb","tc", etc. until the server takes even longer to respond. This allow…

HN discussion@OP: I think you'll enjoy my own hacking of Go's map type here: http://lukechampine.com/hackmap.html Of course, there are all sorts of reasons why this is A Bad Idea, but it's too fun to resist. :)

HN discussionIt warms my heart to see so many people in the comments clarifying that LLMs can indeed be deterministic. This was not always the case! I hope that we will soon see deterministic inference offered by frontier labs (presumably at a premium rate). In the meantime, you can get deterministic behavior from local models using the right vLLM flags. I've described some of the cool applications of determinism here: https://l…
