rmast··on Nanny state discovers Linux, demands it check kids' IDs before booting
The sobriety check requirement for cars is so optimistic:

“Once data prove the tech cuts drunk-driving crashes, insurers may trim rates.”

Why would any insurance company want to cut into their profits by reducing rates?

Age verification passes? Now not only would extra costs be added for users to verify their age, that sounds like an age verification passes is a form factor that could easily be resold to someone else.
rmast··on TCXO Failure Analysis
Interesting how the depackaging was done - curious what the mill setup was looked like. It seems like achieving .001” on manual mills isn’t uncommon; which would be about 25 micrometers, so in line with the depth of passes that were being taken here. I can see how the magnified view of the part would be helpful.
rmast··on Ask HN: Please restrict new accounts from posting
That looks interesting, but I feel like it’s likely to be close to impossible to join. Feels like it would be weird asking someone you know for an invite.
rmast··on No right to relicense this project
If you wanted to do the clean-room approach for something like chardet in a less controversial way, instead of having the AI do all the work couldn’t the AI generate the spec and then a human (with no exposure to the original code) do an initial implementation based on the spec?
rmast··on No right to relicense this project
As part of the relicensing ZeroMQ did a few years ago, they sought permission from all previous contributors (yes, it was a multi-year effort). Code contributions that they weren’t able to get permission to relicense resulting in the corresponding lines being removed (or functionality rewritten from scratch).
rmast··on AI and the Ship of Theseus
I would imagine there must also be some aspect of uniqueness to it as well for even recognizing where a line of code came from… otherwise almost every Python script might have copied this line from a GPL licensed program:

`if __name__ == "__main__":`

I have no idea where that line first appeared, so figuring out what license it was originally written under would be difficult to track down, and most software only has license info at the file rather than line level.

This could be amazing for running Asahi Linux one day. Probably will be quite a while before Asahi works on it though.
rmast··on Microsoft announces new "mini PCs" for Windows 365
Hopefully they support Linux in case Microsoft decides the hardware in them is no longer good enough in the future.
rmast··on Just two days of oatmeal cut bad cholesterol by 10%
It would probably be better to just eat all those different vegetables as part of actual meals to get a varied diet, rather than in pill form.

I was under the impression that more protein and less salt/fat/carbs are still kinda the trend? If more fiber gets added to the mix I guess it is essentially telling people to eat more plants, thus leading to more varied diets overall.

rmast··on Just two days of oatmeal cut bad cholesterol by 10%
All of those things (other than the fruit) have cholesterol. Cheese and meat can also be quite a bit of saturated fat.
rmast··on Just two days of oatmeal cut bad cholesterol by 10%
What do you mean by heart healthy diet?

Egg whites, lean meats, etc? Strict whole food plant based?

rmast··on Show HN: Pkgdex – Search 3.5M Linux/Unix packages across 67 distros
How are you fetching/scraping data from each distro? A lot of parsing pkgbuild files, indices, etc?

Also curious about how long updating/scraping the data took (or takes since I assume you update it periodically).

rmast··on Get free Claude max 20x for open-source maintainers
It's bizarre how they mention NPM for package downloads, and forget that other ecosystems exist too that aren't exactly small... PyPI, NuGet, Cargo, Maven, RubyGems, etc.

I’m not at all affiliated with this project, just came across it and thought it looked interesting - it kind of resembles the sled from a CD drive tray. I could imagine an open hardware version of the printable files being created if they don’t already exist.

A quick search for the stepper motor drivers used shows sets of 5 for around $15, perhaps pair with a cheaper microcontroller than the Arduino Uno and total BOM costs could be $30 or so.

rmast··on Is Show HN dead? No, but it's drowning
I feel the same way, wondering if there’s a point.

That said, I shared a cool post I came across (not a Show HN) about drone hacking. It basically got 0 traction. Not even 10 hours later someone else shared the exact same link and got 100+ upvotes and decent discussion. Which seems to point to a giant element of luck and the right eyes seeing the thing shared.

rmast··on Is Show HN dead? No, but it's drowning
To be honest, I’m feeling mildly discouraged from sharing on HN — there is stuff I think is interesting and got received well when shared elsewhere like Reddit, but appears to not be of interest to other people here.

Though I guess this makes Show HN essentially like the rest of HN where interesting content gets buried and the outcome is entirely random chance. As an example https://news.ycombinator.com/item?id=46648740 went more or less unnoticed, then someone else shared the exact same link less than 10 hours later with the opposite result in https://news.ycombinator.com/item?id=46654749

rmast··on Show HN: Find hidden binary dependencies & subprocess calls in Python packages
unblob is a pretty good one to try if you need inspiration - it pulls in both lief (no abi3 wheels or sdist), and rarfile (subprocess spawning using import “as”).

rmast··on OGhidra: Automating dataflow analysis and vulnerability discovery via local LLMs
OGhidra uses GhidraMCP and Ollama to enable AI-driven binary analysis using natural language to help accelerate software assurance workflows, such as vulnerability discovery and malware analysis.

Some of the main technical details that I find interesting are:

* Agentic loop that uses a "Plan-Execute-Analyze-Review" workflow to navigate binaries

* RAG for context awareness by creating a semantic map of binaries, so relevant cross-references and function definitions can be pulled into the LLMs context window as needed

* Local Ollama LLMs for privacy/security, no data is sent to external APIs

I'm not the author, but we've talked so I may be able to answer some questions about the tool (or ask the author about complex questions).

rmast··on Show HN: Inspect and extract files from MSI installers directly in your browser
What type of data export would you find most useful?

* Tables as a collection of CSV files, or an Excel workbook

* Contents of streams

* StringPool data dump

* Option to configure file dump to export using either SourceDir paths, or target destination dir paths

rmast··on Show HN: Inspect and extract files from MSI installers directly in your browser
It looks like orca.msi uses external cab files, so maybe a bit harder to do than just fetching a single file MSI into the Pyodide file system. If the license allows, it would be interesting to have as an option for the example.
rmast··on Show HN: Inspect and extract files from MSI installers directly in your browser
Thanks for the suggestion! I just added a button to load a small example MSI file.
rmast··on Show HN: Inspect and extract files from MSI installers directly in your browser
My experience with 7zip has been that it can read the tables and cab files from MSI files, but when you go to extract the contents you just get the raw files without the directory restructure associated with the MSI file (and the names of the extracted files can also have issues).
rmast··on Show HN: Inspect and extract files from MSI installers directly in your browser
As a side note, I just tried it in mobile Safari on my iPhone -- at least inspecting MSI files works, extracting files may work as well (not sure where it is placing the "downloaded" zip file).
rmast··on What I think about when I edit (2019)
This reminds me a lot of the writing advice from Jean-luc Doumont’s lecture/workshop 'Clear, accurate, concise writing'.
rmast··on Interview with a blind developer on how he works (2017)
That second thread is really interesting — I don’t think I have to worry about blindness, but I’ve wondered how I’d adapt to working if I couldn’t see, or didn’t have use of one or both hands.
rmast··on Alcohol Use and Mortality Among Couples in US: Individual and Partner Effects
The counter argument for the J curve/French Paradox study is that their data for people who don’t drink is biased — it doesn’t distinguish between people who never drink because they don’t want to, and those who stopped due to underlying health conditions (thus making it appear as if mortality among those who don’t drink is higher).
rmast··on Alcohol Use and Mortality Among Couples in US: Individual and Partner Effects
I think there’s been research regarding the supposed “J-curve” for alcohol consumption — essentially, the original research that led to the idea of moderate consumption being better than none failed to differentiate between people who have never had alcohol, and those who stopped drinking due to health conditions. I wouldn’t be surprised if this “couples drinking together” also has a similar bias.
rmast··on Ketogenic Diet Intervention on Metabolic and Psychiatric Health
If you don’t like what the research says, then comment so we can have a discussion rather than downvoting because it goes against your mental image of Neanderthals.
