You can search for emails in Gmail, “Select All” and Gmail will prompt you, “do you want to select all conversations that match this search?” rather than just the 100 you can see. Then if you do something like use the Archive keyboard shortcut it says “do you want to apply this to all conversations selected?” Previously this was instant. Now it says, “We archived some conversations. We’ll do the same for any remaining conversations in a few minutes. This might take longer, depending on how many conversations are selected.” And if you go back to your Inbox they’re still there. A real downgrade!

This is what I want to do but it fails passing None to assertRaises:

tests = [
   (0, None),
   (1, None),
   (-1, TooFewException),
   (99, None),
   (100, TooManyException),
]
for n, exc in tests:
    with self.assertRaises(exc):
        results = my_code(n)
        assert len(results) == n

Here’s a version of assertRaises that will let you do that:

    def assert_raises(self, exception: Type[Exception]):
        if exception:
            return self.assertRaises(exception)
        return contextlib.nullcontext()

Number of lines in a (python + js) codebase:

#!/bin/zsh

# This script counts the number of non-blank lines of code in a directory and its subdirectories
# for Python and JavaScript code only

# Set the directory to search for code files
dir='.'

# Count the number of non-blank lines of code for Python and JavaScript files
num_lines=$(find "$dir" -type f \( -name '*.py' -or -name '*.js' \) -not -path '*venv*' -not -path '*node_modules*' -exec grep -he '^[^[:space:]]' {} + | awk 'NF{count++} END{print count}')

echo "Number of non-blank lines of code: $num_lines"

Number of lines per-file in a (python + js) codebase:

#!/bin/zsh

# This script counts the number of non-blank lines of code in a directory and its subdirectories
# for Python and JavaScript code only

# Set the directory to search for code files
dir='.'

# Count the number of non-blank lines of code for Python and JavaScript files
num_lines=$(find "$dir" -type f \( -name '*.py' -or -name '*.js' \) -not -path '*venv*' -print0 | xargs -0 grep -cve '^[[:space:]]*
)

echo "Number of non-blank lines of code: $num_lines"

>>> from urllib.parse import urljoin
>>> urljoin('http://example.com/', '1')
'http://example.com/1'
>>> urljoin('http://example.com/', '2629:1828:4025')
'2629:1828:4025'

Better not try to urljoin anything with a colon in it!

I was encountering a situation where big aggregating queries that took seconds on local were taking minutes or even hours on prod. After trying about a million things this Stack Exchange post finally cleared things up.

Setting innodb_buffer_pool_size = 5G in MariaDB’s configuration and restarting instantly changed the queries to taking seconds. The default is 128M which is … not useful 🙂

Save this as “ssh” somewhere on your $PATH ahead of /usr/bin/ssh and make it executable

#!/bin/sh

HOSTNAME=$(echo $@ | sed 's/.*@//')

set_theme () {
    osascript -e "tell application \"Terminal\" to set current settings of first window to settings set \"$1\""
}

on_exit () {
    set_theme "Solarized Light"
}

trap on_exit EXIT

case $HOSTNAME in
  # These all do the same thing but we could have different themes for different locations
  hb|pd|decksite) set_theme "Solarized Dark" ;;
  *) set_theme "Solarized Dark" ;;
esac

/usr/bin/ssh "$@"

“rust cargo unable to update registry attempted ssh-agent authentication, but no usernames succeeded: `git`”

I got this error trying to cargo build with a new dependency in the manifest. Fixed with:

eval `ssh-agent -s`
ssh-add
cargo build
