Thoughts on web design, security, crypto...
And yes, I wrote most of this page in nano. Via PuTTY. And it was fun. Mostly. Somewhat. For a moment.

PGP key
* Actually here’s an update: at some point, GnuPG removed support for excessively large keys, so my key doesn’t work anymore.
I’ll be checking up on it from time to time, until they implement post-quantum crypto, and then create a new key once this is available.
It looks like it might be Coming Soon(TM), hurray!
Little update on 2025-07-26: gave a try at a ML-KEM-1024 key with GnuPG 2.5.7: creating the key worked, but not encrypting to it, and
signature still uses non-PQC anyway. So... I’ll keep an eye on it and try again later.
Also, hi
I really just set this up in order to give a little something to whomever gets curious enough about my e-mail. Hi, you ^^

Software
Oh, a new section... with not much here yet, but this should grow, given enough time.
-
SimtinHTTP, a simple
and tiny HTTP server written in Rust.
Since it’s hosted by itself (don’t let the Apache header fool you, it’s proxied)
and doesn’t support HTTPS (and I haven’t yet gone through the headache-inducing
trouble of configuring Let’s Encrypt on that kind of setup),
I guess I should provide a couple of SHA256 hashes:
- simtin-http-0.8.0.exe (Windows x64): 99c3ec93eeef5f471cc1379b1f98b0132b782874077e6f2e04f387abc7d4a226
- simtin-http-0.8.0-musl (Linux): 49c0ea404f044bc0576b2a81ff336bfea33afd46abdb86ed960f6ab71346624e
I also provide automatic builds here,
if you prefer the very latest thing (might be buggy sometimes).
-
list-features, a Rust
crate that extracts the list of enabled feature flags during compilation.
I wrote it because I didn’t find something suitable (small / no deps, low
MSRV) for use
in SimtinHTTP and other projects.
-
fifo-cache, a minimalist,
thread-safe, FIFO (First In, First Out) cache with TTL (Time To Live) support for Rust.
Same motivation for writing it as for the list-features crate.
-
CompanyFlag, a browser
add-on (manifest V3) that shows the country of origin of the current website’s company.
Here it is for Firefox
and for
Edge.
For the other browsers with MV3 support, it can be installed from source or from
the Gitlab pipeline’s artifacts.
