On Linux, the mtime ("modification time") is indeed automatically updated when the content is changed, but it can also be set arbitrarily from userspace (e.g. using `touch`) without special permissions. This is very useful, e.g. w

Very good point! If you don't mind saving the file to disk, you can do: sqlite3 -newline '' ':memory:' "SELECT data FROM zipfile('eurofxref-hist.zip')" \ | sqlite3 -csv ':memory:'

You should use "/" instead of "-" in your equations. If you have two objects of the same density but with different sizes, the ratio of their (apparent) weights will be the same in air and in water, but the differen

Tangential, but regarding footnote 7 (efficiently recomputing cells, assuming no cycles), the correct algorithm for determining the order is topological sorting ( https://en.wikipedia.org/wiki/Topological_sorting ). Usin

I'd first check whether `git fsck` gives you more information. There isn't a simple and fast way to find parent objects, but here is a slow hack: git_find_references() { if [ "$#" -ne 1 ] || [ "${1#-}&

Sure! (My explanation is basically equivalent to the combined explanations by @mafuy and @malcolp, but I'll post it anyway.) The idea is to balance a scale with the crown on one side and an equal mass of gold on the other side (no wate

Google certainly uses its geolocation DB, but it also learns based on map browsing patterns. To clarify, the scenario I described is as follows: 1. Initially, when I open Google Maps in a clean browser it defaults to my real location. 2.

Somewhat relevant: Google Maps can learn the location of your IP based on which locations you browse in the map. If you browse a specific location enough times, it will use that as the default location when you open Google Maps, even if you

There are a couple of confusions/ambiguities here. The Law of Large Numbers is about the average , so it's not relevant here (an average of +1 would mean you got heads every single time , which is extremely unlikely for large n)

The answer is almost certainly "abuse". Traffic is routed through a "service hosted in Azure" (probably not GitHub specifically). They're just using GitHub sign-in to apply per-user limits etc.

If netcat is installed, just use that instead (it's also better for non-telnet protocols). If you don't even have netcat but you do have bash, you can use: bash -c 'exec 3<>/dev/tcp/$host/$port;
