💾 The File Count Challenge 🔎

Have you ever wondered how many PDFs, images, videos, or particular kind of files you have on your device? It is the time to find out.

I am hereby proud to officially launch a Fedi-wide file count challenge, in exclusive partnership with the 2025-27 class of @xpub 👾

💁 How to participate

1. Go to your main device (not mobile)
2. Open the terminal
3. Run find . | grep '.pdf$' -c (on Windows: gci -r | where Name -match '\.pdf$')
4. Repeat the previous command, replacing “pdf” with any file format you are interested in sharing. We suggest: jpg, mp3, and png. 🔆 Bonus: html, js, ttf, odt, svg
5. Take a screenshot of the output
6. Share the screenshot on the Fediverse, using the #fileCountChallenge hashtag (please, copy-paste the actual text from the terminal in the image description/alt text)
7. Add your (user)name and results to the scoreboard
8. 🆒 Bonus: share the story explaining why you have so many/little files for one format.

🏆 Awards

There is a secret prize for the three people who have the most PDFs, JPEGs, and HTMLs. More info to follow.

Boost, share, fork… Do whatever you want, but please have fun while doing it.

I willl keep writing updates. Yaaaaaaay ⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️

The challenge: to develop a fully autonomous system capable of neutralizing small and micro UAVs (Unmanned Aerial Vehicles) of up to 25 kg and 200 km/h autonomously, precisely, and non-destructively in real time—without explosives, without kinetic means, and without collateral damage.

#Christmas #coding #challenge: write a program that prints the full lyrics to the Twelve Days of Christmas, but be #weird about it.

Choose whatever programming language you like. Use the language’s idiosyncrasies to your advantage.

For example, in C you might blend a for-loop with a switch-statement and liberally use case fallthrough. In BASIC you might use computed GOTO. In HTML+CSS you might use counters and selectors to do the numbering. In SQL you might use SQL.

Go.

Submissions so far in: awk, C, Clojure, Haskell, JavaScript, LINQ, Lua, nu, Perl, PostgreSQL, Powershell, Python, Ruby, Rust, Terraform, XQuery, XSLT, as well as a hardware implementation on an Arduino and a couple of very cool visualizations.

Just released: #swad 0.12 🥂

swad is the "Simple Web Authentication Daemon". It basically offers adding form + #cookie #authentication to your reverse proxy (designed for and tested with #nginx "auth_request"). I created it mainly to defend against #malicious_bots, so among other credential checker modules for "real" logins, it offers a proof-of-work mechanism for guest logins doing the same #crypto #challenge known from #Anubis.

swad is written in pure #C with minimal dependencies ( #zlib, #OpenSSL or compatible, and optionally #PAM), and designed to work on any #POSIX system. It compiles to a small binary (200 - 300 kiB depending on compiler and target platform).

This release brings (among a few bugfixes) improvements to make swad fit for "heavy load" scenarios: There's a new option to balance the load across multiple service worker threads, so all cores can be fully utilized if necessary, and it now keeps lots of transient objects in pools for reuse, which helps to avoid memory fragmentation and ultimately results in lower overall memory consumption.

Read more about it, download the .tar.xz, build and install it .... here:

https://github.com/Zirias/swad

There's a lot that could still be improved in #swad, but I don't get that "proof of work" idea out of my mind, so I started a branch to work on it:

https://github.com/Zirias/swad/pull/1

I really think it makes sense when you want some publicly known "guest login" which is still protected against #bots. Not sure yet whether this will succeed, we will see!

It certainly won't be as "fancy" as #anubis, but do the same thing functionally: Require the client to find a #nonce that, combined with a server-provided #challenge, hashes to something with 'n' leading zeros using #sha256. In contrast to anubis, swad won't have to proxy everything (but rely on nginx' auth_request), and no challenge will be issued when the user logs in with credentials some other credentials checker accepts.
