Since the contents are in-memory, you could imagine a straightforward implementation where the directory hierarchy in the tmpfs is stored in a pointer-based in-memory tree. A file handle just needs a pointer to where in memory the contents

Digital elevation models typically represent terrain elevations in a grid of square cells of some cell size, e.g. 1 meter by 1 meter. Such a model is rarely useful unless it also has georeferencing information, i.e. coordinates for the boun

Simple scheme for deduplicating strings in Python: dedup = {} for s in strings: s = dedup.setdefault(s, s) # Do something with s It hashes each string "s" and looks in the dictionary "dedup"

Using a simple shell for-loop, I could create 10000 commits in 25 seconds (= 400 per second) with the code below. The 4.2 million commits should take around 3 hours to create at this pace. Looking at the most recent 10000 commits in the rep

Let me give an example to explain what I mean: I would hope that switching keyboard layouts would work the same as switching between windows of open applications with Alt-Tab. That is, open a web browser, then open a text editor, then open

Is that how the cycling works? I would hope that, just like with Alt-Tab, pressing the language bar hotkey Windows-Spacebar once will toggle between the current and the most recently used one.

You're right that there's a lot of nuance to the set up. I think listing that directory will solve the "it's 4:00 am and you want to know if nginx will start on boot" scenario, but you're right that you need to

You cannot access "bot" inside bot.on_speak(|| { ... }) because Rust does not know that the "bot" variable stays alive for whenever the callback is called. In this situation I would expect "bot" to be stored in
