The RAM vendors have formed cartels previously and been convicted, so although demand is exceeding supply it is not that crazy to at least consider.

I recently learned that nylon 11 (sometimes aka PA11) is made from castor oil, which (I also learned) is just the vegetable oil extracted from the castor bean.

Yes, if anything the issue is that the House was capped in seats in 1929 and the population has tripled. Smaller states have an outsized representation in Congress currently.

The contradiction he's pointing out is that they often speak out against so-called "illegals", but as you've documented they enjoy it when business reap the benefits of undocumented labor (i.e. wage suppression).

The excessive amount of emdashes does seem to imply it's LLM slop ragebait. The prompt probably included "make intentional mistakes in your arguments to drive engagement" or something like that.

I haven't downloaded your model but https://www.i-solids.com/ (US-based, FDM and MJF) and https://www.weerg.com/ (Italy, mostly MJF ) will both do instant quotes and you might get reasonable prices from them at scale. PCBWay and JLCPCB in China will also do 3d printing at reasonable volume, if you want to get an idea of a baseline price.

Thanks! Feel free to file an issue if there's something missing from the library or the daemon.

Thanks for writing the blogpost! I think it's perfectly valid as a fun demonstration of the utility of the wayback machine.

The `parse_program` function is public inside the `bc_util::parser` module, and the parser module is marked public inside `bc_util`, but in the `calc/src/bc.rs` file the `bc_util` mod isn't public, and can't be accessed from a test inside the `tests/` folder, which only has access to the public API exported by the library.

There are several sites with instant quotes that are cheaper than Shapeways.

PCBWay and JLCPCB both offer similarly-priced very cheap 3d printing and CNC services out of China. Weerg in Italy also offers 3d printing and CNC services and I'm probably going to try them out for the next thing I need printed. The only non-marketplace service I've seen in the US that offers instant quotes is i-solids in Texas, but they have quite high startup costs and seem to be more geared towards small-medium production runs.

I'm not sure if it's related, but I have the git branch in my PS1 and I've noticed that it's much slower to show a new prompt when inside very large repositories now, and I don't think that was the case previously.

Linux has seccomp and landlock, which are basically harder-to-use versions of pledge/unveil.

Since the author mentioned rewriting it in Rust, I recently added support to my library extrasafe that allows you to sandbox your own code: https://harrystern.net/extrasafe-user-namespaces.html

So if you wanted to call ffmpeg or some other C library with complicated user-provided data, you can use extrasafe's Isolates (along with its seccomp and Landlock features) to sandbox the call. I'm not really sure how suited it is for rewriting something like bubblewrap or firejail, but it might be interesting to try.

I made a Rust library and cli tool that starts a clean postgres instance for each test. The daemon version transparently proxies your connection to a new postgres server every time you connect to it.

New comment by boustrophedon in "The bane of my existence: Supporting both async and sync code in Rust"

boustrophedon — Fri, 19 Jan 2024 23:57:54 +0000

I think the biggest underlying difference is that Rust does not have a language runtime, whereas the other three you've listed do. Since the language runtime can preempt your code at any time, it becomes a lot easier to make async work - at the expense that now data races are easier to create.

I'm not going to pretend I'm an expert but would be happy if someone could expand further.
