I wrote some code to do almost this many years ago (if I recall correctly, it doesn’t cache anything to disk, but builds the hash fresh each time, which can still result in massive…

> Plus they get to keep the balance that people forget to redeem I'm not an expert here, but this is not generally true. See "giftcard escheatment laws". I think these vary by stat…

If that phrase "for individuals" means "for individuals only", then it isn't GPLv3, but some bespoke non-free license. My speculation: it was intended to mean: use it under terms o…

I tried to like OCaml for a few years. The things that hold me back the most are niggling things that are largely solved in more "modern" langs, the biggest being the inability to …

Could be xscavenger? > Scavenger is a cool arcade/thinking game very much like Lode Runner. You've got to run around and collect objects while avoiding enemies. Some objects are bu…

Just to add, 'pass' has an otp extension to simplify this a bit [1] With that, you can do $ zbarimg -q --raw qrcode.png | pass otp insert $ pass otp # or pipe to xsel [1] https://g…

Can you explain further? I'm not sure I follow. > How do you as a method author opt in to distinguishing between [break and next] after yielding to a block? I don't use Ruby much l…

Used "in anger" means "professionally" or "for real" or "where working or not really matters" vs. using it for hobby projects or experimentation.

Many years ago (2011 or so?), I worked on a Rails app that used JRuby. The driving force was a small part of the app needing a Java library. I think we did see some performance ben…

There's Cliff Young's win in the 875km Westfield Sydney to Melbourne Ultramarathon. > While the other competitors stopped to sleep for six hours, Young kept running. He ran continu…

For 1., it's possible (easy even? I've never tried this in a cross-compiling situation) to build packages on one system and push them to another via SSH. I suppose an upgrade would…

For what it's worth, Linux 5.6 introduced openat2 [1] which accepts some additional flags controlling path resolution. For example, RESOLVE_IN_ROOT "is as though the calling proces…

Not sure if this would help, and I'm not exactly sure I'm understanding you correctly, but when I tie hockey stakes, instead of a single "left-over-right starting knot" (using term…

I stopped using `set -e`. It is disabled if the function you're running is part of an `if` statement, for example: thingThatCanFail() { echo "step one succeeded" echo "step two fai…

Here is (I think) the example regex ported to OCaml's Re library [1] let my_regex = let open Re in seq [ bos; opt (str "0x"); repn ( alt [ rg 'A' 'F'; rg 'a' 'f'; rg '0' '9'; ] ) 4…

Note that Apache Tomcat is an implementation of Java Servlets, not to be confused with Apache httpd, the venerable web server.

This doesn't answer your question, but I'm piggy-backing with comments on k3s. For me, using k3s for development (not prod), the killer feature is running it in --docker mode where…

It's not a contradiction to state something is not a problem most of the time. (Though the next point, calculating checksums prior to build, is much more significant.) Related exam…

Hi Paul, thanks for Ardour. For anyone curious, this wiki page describes how to package and run some precompiled binaries on NixOS, particularly the section "The Dynamic Loader": h…

That's an interesting point. But it's not just rpaths, there are many references to things within the nix store. I suspect it would quite difficult to make them bound at runtime or…
