Copilot, Cursor, Claude Code, etc are convenient for automatically pulling relevant files from your codebase when asking questions but with difficult or sprawling questions I get much better results by manually selecting the files I want to include. To simplify this manual process, I wrote a small script named catcopy. What catcopy does catcopy takes a regex pattern, searches the codebase for matching filenames, gets the contents of each, and copies to the clipboard broke up with big markdown headers. ...

View the commit history for a particular file with git on the command line: git log --follow -p -- filename

Full screen is super annoying on OS X lately. I use SizeUp which gives me a shortcut for expanding the windows instead of using the green button but i’m still having random encounters with full screen mode because of the shortcut ctrl+shift+f. So here’s how to disable that..or at least make it harder to do by accident: # Change full screen shortcut to Shift + Ctrl + Opt + Cmd + F defaults write -g NSUserKeyEquivalents -dict-add "Enter Full Screen" "$~^@F"

The easiest way to update git to 2.2.1 or higher is to use homebrew. brew install git If you get a command not found error, you can install homebrew from brew.sh (scroll down for a one liner, i won’t copy it here in case it updates). If you get a different error, check out Updating homebrew on yosemite.

Python’s get_tld works very well but is slow if you’re looking up a batch of domain names. Here’s a faster version that falls back on get_tld: from tld import get_tld import re def quick_tld(url): tld_prog = re.compile(r'(?P<tld>[^./]+\.(com|net|org|co\.uk))($|/)') ip_prog = re.compile(r'\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b') try: tld_match = tld_prog.search(url) if tld_match: return tld_match.group('tld') elif ip_prog.match(article.url): return None else: return get_tld(url) except Exception as e: pass return None

The octet_length function returns the length in bytes size of a bytea field. From the docs: “Number of bytes in binary string”. SELECT octet_length(the_data_field) FROM table_name; # byte size More binary string functions
