Really incredible Norther Lights a couple weeks back. There really was this much pink "live".

Am I doing the survey right?
(Canada doing a very one-sided and leading "survey" on how to bury our heads in the sand more effectively ... oh I'm sorry I mean "sustainably encourage AI")

"How can we encourage sovereign infrastructure" they wring their hands […]

[Original post on mastodon.social]
A dumb question ("how can we ensure equitable AI access?") with a pithy answer ("implement UBI immediately").

New releases of Fowl, ShWiM (shell-with-me) and Git-WithMe

https://github.com/meejah/fowl
https://github.com/meejah/shwim
https://git.sr.ht/~meejah/git-withme

Includes cool new ANSI logos from @littlebitspace which I'm personally very excited about :)

#python #magicwormhole #infosec
"fowl" running in a dark-mode terminal, showing a ANSI / text-mode art with big "fowl" text in chicken theme and a rendering of the Fowl logo in ANSI.

@shapr and I re-started our "reading something interesting" group, this time https://web.evanchen.cc/napkin.html

I was puzzled by 1.1.10 but working out this #python snippet helped:
Example 1.1.9: Why does P need to be prime to make (Z/pZ)x a group? def has_inverse(n): for x in range(1, n): if 1 not in [x * y % n for y in range(1, n)]: print(f"{x} doesn't have an inverse in Z/Z{n}") return False return True print([n for n in range(2, 100) if has_inverse(n)])

ShWiM in action.
Although this is between two terminals on the same computer, this works the same between any two computers (behind NATs, whatever).

Very excited about some new ANSI goodness coming in the next https://github.com/meejah/fowl release (along with some "real" enhancements and bug-fixes).

Art by @littlebitspace
The head of the output of "fowl --readme" with an inline ANSI version of the Fowl logo (a chicken head with two ethernet cables coming out of it).

Reminder that you can use "cuv" / Cuvner (https://github.com/meejah/cuvner) inside your CI runs to avoid depending on another service. Especially easy for #python projects.

See my blog for more detailed instructions: https://meejah.ca/blog/cuvner-pull-requests

I have just released version 25.9.0 of ShWiM ("Shell With Me") for encrypted, peer-to-peer terminal sharing.

https://pypi.org/project/shwim/25.9.0/
https://github.com/meejah/shwim

#magicwormhole #infosec #shell
A terminal UI for ShWiM showing a spinner waiting for a peer to connect. There is some text about what "shwim" does, a random magic code and connection information displayed.

The "hello world" of #p2p applications for #infosec is "chat", right?

Here we use Fowl to make end-to-end encrypted and durable (survive IP address changes) chat using "nc" and "telnet"...

#magicwormhole #twisted #python
A screenshot of four terminals. Two are "dark" on one host, and two are "light" on another host. Each host runs a "fowl" command, one "fowl --service chat" and the other "fowl --client chat". One host runs "nc" to listen for connections and the other runs "telnet" to connect. End-to-end encrypted nc+telnet chat over fowl + magic-wormhole.

fowl 25.7.0 is released.

Extensively re-thought internal and external APIs, centered around giving each peer maximum control, while being safe by default. Peers must opt-in to non-localhost networking of any kind.

ShWiM coming very soon for your peer-to-peer programming needs.

#magicwormhole #p2p
A logo for "shwim", or "SHell WIth Me", another Magic Wormhole and Fowl-based proof-of-concept tool that accomplishes real work: share a terminal between two computers.

@shapr told me about "btop" https://github.com/aristocratos/btop which is a really nice-looking terminal app for process monitoring.
Great use of unicode and colour!
(There is also support for GPU monitoring)
Screenshot of a dark-mode terminal running "btop" which is using various unicode braille characters to graph CPU, memory and network usage with nice colours and a list of processes

Now merged to main in fowl
https://github.com/meejah/fowl

coming soon to a release :)

#magicwormhole #networking #infosec
Screenshot of 4 terminals in a 2x2 grid. The two topmost terminals are running "fowl" connecting two peer computers. The bottom left terminal runs "nc" on a local port and the other runs "telnet" to a localhost port -- the connection is streaming over magic-wormhole, which shows a traffic-graph in the two top terminals.

I have made a release of "git-withme" which allows peer-to-peer Git usage over #magicwormhole

This uses short, human-memorable codes to invite peers to collaborate (push, pull, etc) in real-time on a Git repository with no external hosting providers. Creates […]

I love that there's still some really cool ANSI art being produced, like I remember on the very best BBSes ;)

For example https://16colo.rs/pack/impure89/impure89.ans

Does anyone take commissions for these sorts of pieces? Nothing nearly as elaborate as […]

Lots of fun diagrams! Feedback welcome :)

Want visualization of your coverage diff without using some third-party service?

See https://meejah.ca/blog/cuvner-pull-requests
#python #coverage
Part of a GitHub actions run, with a step called "PR Coverage Graph" shown. It is displaying the tail end of terminal output from "cuv diff -" which says how much of a particular diff is covered by unit-tests.

magic-wormhole 0.18.0 is released.
