Python regular expressions for IPv4 and IPv6 addresses and URI-references, based on RFC 3986's ABNF.The URI-reference regular expression includes IPv6 address zone ID support (RFC 6874).
# Python regular expressions for IPv4 and IPv6 addresses and URI-references,
# based on RFC 3986's ABNF.
#
# ipv4_address and ipv6_address are self-explanatory.
# ipv6_addrz requires a zone ID (RFC 6874) follow the IPv6 address.
# ipv6_address_or_addrz allows an IPv6 address with optional zone ID.
# uri_reference is what you think of as a URI. (It uses ipv6_address_or_addrz.)

How is git commit sha1 formed

Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺

Locally, I'm at this commit:

$ git show
commit d6cd1e2bd19e03a81132a23b2025920577f84e37
Author: jnthn <[email protected]>
Date:   Sun Apr 15 16:35:03 2012 +0200

When I added FIRST/NEXT/LAST, it was idiomatic but not quite so fast. This makes it faster. Another little bit of masak++'s program.

The list would not be updated for now. Don't write comments.

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.

Because of GitHub search limitations, only 1000 first users according to amount of followers are included. If you are not in the list you don't have enough followers. See raw data and source code. Algorithm in pseudocode:

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Random alphanumeric (base-62) strings in Node.js, cryptographically strong
var bases = require('bases');
var crypto = require('crypto');
// Returns a base-62 (alphanumeric only) string of the given length:
function randomStr(length) {
// We generate a random number in a space at least as big as 62^length,
// and if it's too big, we just retry. This is still statistically O(1)
// since repeated probabilities less than one converge to zero. Hat-tip to
// a Google interview for teaching me this technique! ;)

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)
