I'm looking for employment again.

I'm good at Python, Git, Linux, and Django.

I have experience with CI/CD and AWS.

I'd be very excited to work for a nonprofit or to grow skills in Rust, Haskell, or embedded development.

I'm looking for part-time work but I'd consider a full time position that's flexible enough. I'm good at remote work; I cannot relocate.

To obtain a position that meets my needs I can in turn be flexible about compensation.

Available: October 1.

OMG I only now just realized

florp

is short for

3½-INCH FLORPPY DISKETTE

dear lazyweb, i got a short but deep scratch in the door of my car. what's the best fix? body shop or diy? i don't care at all how it looks but i don't want it to start rusting.

Acknowledging that people are busy and e-mail is a burden, I try to make my (business) e-mail communications fairly terse.

That means I typically won't follow up a conversation with a one-line "thank you," that sort of thing.

I often wonder how many people think this lack of politesse is more rude than it is respectful of their time.

With a little modification to @whitequark's key-printing script I now have a scannable paper backup of my GPG secret key. Pretty cool!

Their original + blog post: https://lab.whitequark.org/notes/2016-08-24/archiving-cryptographic-secrets-on-paper/

Each barcode square encodes about 1.5k of data.

So if you want to sign and decrypt stuff with your GPG secret key, but you want to keep it with you as you move from computer to computer, you can put it in a "smart card." Then the computer you're using asks the card to do crypto for it, and the key never leaves the card.

One very popular implementation of "smart card" is the Yubikey 4, but they're 50 bucks on Amazon.

Today I learned you can re-purpose a $2 STM32 programmer to be a poor man's Yubikey!

Here's one way I found, abusing ANSI escape sequences.

for n in range(1, 50):
print(n, end="\033[G")
if n%3==0: print("fizz", end="")
if n%5==0: print("buzz", end="")
print()

I expect you would do something similar in C or assembly by mutating a string buffer to be output at the end. (And in those languages it would actually result in a shorter program.)

(But, ew, I'd prefer the longer versions that don't need to mutate a string or mess with the cursor position.)

FizzBuzz: for each n, emit "fizz" if n is a multiple of 3, "buzz" if a multiple of 5, "fizzbuzz" if a multiple of 15, n otherwise.

for n in range(1, 50):
if n%15 == 0: print("fizzbuzz")
elif n%3 == 0: print("fizz")
elif n%5 == 0: print("buzz")
else: print(n)

Trivial obvs.

But recognizing that "fizzbuzz"' is "both fizz and buzz" while "multiple of 15" is "multiple of both 3 and 5" hints at an optimization that avoids one modulus operation. Can we take advantage of that?

You can use "keybase verify" to check that this message is signed by the PGP key connected to my #keybase account:

BEGIN KEYBASE SALTPACK SIGNED MESSAGE. kXR7VktZdyH7rvq v5weRa0zkQK9sn6 ovrRjLvVtdvEWy4 Se5C05jmES1Q5iV 7iqVTYz4LnzykQE Xhdt1wtt6cccx5w HzG5V4d5uM5ctAD b7pFWs4Hne4QY8x rhVcS8kubLOrWau 0msnCFilFboglJc XSTRaSIYsRzwx2j UwS3zqvWqVMLKzf 5ijeIISa61J5ecE ARDCEbqhLLgkkpd f65T99rXEGhqovt cl2jr. END KEYBASE SALTPACK SIGNED MESSAGE.

I'm not entirely sure yet what the use case is for several of the features keybase.io offers, but one thing I know it does well is popularize my PGP public key in a fairly trustworthy way and let me easily obtain other peoples', without having to attend a key-signing party or learn which keyservers are good.

I've recently been trying to make more use of PGP/GPG despite how painful the UI is.

So if you use it, please feel welcome to "follow" me: https://keybase.io/datagrok

Here's a little piece of code/art that's been on my mind for years, that I never got around to attempting. Luckily somebody else did it first and shared the source code, which I just stumbled across.

Unlife runs Conway's Game of Life backwards so you can create a start-state that eventually produces an arbitrary desired state.

Created using unlife, golly, giffer.py plugin for golly, and gimp.

Hey #lazyweb, what's the current best way to do #git stuff from a python script? (for automation purposes)

- subprocess.check_output() for full control over plumbing?
- some well-maintained native-python git library?
- other?

"I want to hack on this but it wants a postgresql database and i don't want to mess with sudo... can't I just be like 'run a little postgres over here, as me'?"

Yup 👍

export PGDATA="$PWD/pgdata"
export PGHOST="$PGDATA/sockets"

pg_ctl init

mkdir -p "$PGDATA/sockets"
echo "unix_socket_directories = 'sockets'" >> "$PGDATA/postgresql.conf"
echo "listen_addresses = ''" >> "$PGDATA/postgresql.conf"

pg_ctl start

psql # i'm in

some clients might need:

export PGDATABASE="postgres"
export PGUSER="$USER"
