This is really interesting! I wrote a mini Lisp interpreter in Rust while following along with the book! I ended up using a generational arena to store objects too, but I used a "slotmap", which I wrote myself but is similar to th

I think you should at least understand the basic concepts like loops, variables, pointers and whatnot before trying to follow the book, otherwise it may be a little rough. You definitely don't need any expert knowledge though! Also fol

I think a tmpfs on Linux on some fast DDR5 RAM may get you close, it may even be faster but I'm not totally sure! Of course, getting 256GB of DDR5 or even DDR4 RAM is going to cost quite a lot, and most motherboards probably won't

Wolfram alpha can solve mathematical expressions like this as well, for what it's worth, and it's been around for a decent amount of time.

Common Lisp is also a dynamic language. In CL, classes can be redefined at runtime and the changes effect already instantiated instances! This is just an example, not the only dynamic feature of course. Common Lisp has SBCL which generates

IMO the thing that makes lisp so powerful is the ability to extend the syntax, and this is only possible because the syntax is represented as a list. When your syntax can be manipulated like data (in this case lists), macros become regular

Python supports generator comprehensions too!

Whoops! The Gentoo use flag on swayidle says elogind : Enable support for rootless session via elogind I think this is just a generic description shared between all packages with this flag though! Maybe I can suggest that this be f

None of Waylands internal functions between a client and compositor are blocking or synchronous to my knowledge. Generally you fire off a message and will later receive an event back from the compositor, which is happening in an event loop.

Yes I can confirm that Wayland runs fine without systemd! I am on Gentoo and using openrc and sway runs fine. The only thing that might kind of rely on systemd is sway-idle which wants logind (or to run as root iirc). I know you know this,

Panicking when writing out of bounds is not a bad thing though, this is the behavior you want , assuming you can't statically guarantee that indexes are always in bounds. It is true though that the underlying unsafe rust in std, or cr

There is a lot of code that can't run in a WASM sandbox, like drivers for example. I do think more things running in WASM or WASM-like VM's could help a lot, but I'm not sure what the GPU part is supposed to mean.

You can zip a zipper to combine them, but you end up with an item like (a, (b, (c, d))), not a huge deal since it gets destructured automatically. The itertools crate has a multizip function/macro that allows zipping as many iterators

Well to be fair, I think this is less of an issue of maps being inaccurate and more people blindly following it without considering whether or not their truck can fit down the roads. Maps does not have a "truck mode" that refuses

I used to drive a box truck at work and I can definitely confirm that google maps is used heavily. I used Google maps during almost every trip! Finding random addresses in places you aren't familiar with can be difficult and waste a lo

Do you have more info about this limit? I have never saw that mentioned anywhere and am curious about what the limit is. I use this service to show the current temp and weather with waybar right now and have it set to update on a random int

Yeah these are all very valid issues! I imagine it would depend on the specific use case and how much computing power you need. Also the energy going into the production of the phone should be considered as well. Being able to remove the ba

I think encrypting your boot partition and kernel is not very useful. The "better" (IMO), would be to sign the kernel and use secureboot, but otherwise leave it unencrypted. This way the kernel and whatnot can't be tampered w

The person you responded to didn't mention anything about wanting people to stop talking about it. >Prove it? Or just desperate to convince yourself? I don't even know how to respond to this. The people who developed the thing

I did not realize you were a Gentoo contributor when I first responded! This is an interesting problem for sure. I don't know enough about portage internals to know whether it could be fixed easily, but it would be very nice to have. S

You can build binaries on Gentoo and update from the binaries you've built rather than compiling as you go! You can build binaries for all of the packages that need to be updated by running the normal update command and adding "--

This is pure misinformation at best. A masked package is generally caused by something not being stabilized yet, which can be fixed by adding the package to the package.accept_keywords file. Sometimes a package with known issues, such as se

My ~$200 Moto G has 8 arm cores, 4G ram and 64G EMMC storage. That is actually significantly more powerful than the VPS I pay monthly for, and could easily host git repos, a website, irc bouncer, and much more, and the hardware is already

>Firstly SHA is not a secure hash. This is incorrect, but even if it were true, you could use whatever your hash of choice is instead. Gentoo for example can use whatever hash you like, such as blake2, and the default Gentoo repo capture

I am not sure how you could not rely on GitHub when packaging code that is hosted on GitHub. My personal Gentoo ebuilds for example contain a URI variable that points to the GitHub auto-generated archives for projects that use GitHub for ho

I am not sure that something like a crate distro would actually cause a decrease in stability overall, at the end of the day people are still going to be using the same crates and those crates will be as stable as before, but it will be eas

These aren't even close to comparable, and I am very tired of hearing people complain about this! My current Gentoo system seems to have existed since 03/29/21, so roughly two years now. In the time period, the time spent com
