I just love steganography. I have an SVG and a PNG with malware I use to test file uploads.

I've made a thing! A new version of an UUID encoding I came up with 12+ years ago. There might even be one or two people here who remember me giving my first Tech Talk at work about this back then.
Next to the PostgreSQL version that I shared, I always had implementations in the languages I worked with, and I improved the encoding a bit further in the last years, and just published an implementation in Go:
Random advice peeps: do not use `btoa` for encoding in production.
> Failed to execute 'btoa'. string to be encoded contains characters outside of the Latin1 range.
Use something like `Base64.encode` instead
Mam plik tekstowy oryginalnie napisany/zapisany na Windowsie XP w notatniku. Jest po polsku.
Niestety jak go teraz otwieram to mi wyskakują krzaczki gzie powinne być polskie literki, bo nie ten zestaw znaków.
Czy ktoś wie jaki zestaw znaków używał polski Windows XP w notatniku?
@74 i @dos informują mnie że to Windows -1250! Dziękuję pięknie i jutro będę próbowała zmienić zestaw na jakiś bardziej nowoczesny

Hexlish Alphabet for English, Constructed Languages and Cryptography: Automatic, Structural Compression with a Phonetic Hexadecimal Alphabet
DOI : https://doi.org/10.5281/zenodo.13139469
Hexlish is a legible, sixteen-letter alphabet for writing the English language and for encoding text as legible base 16 or compressed binary. Texts composed using the alphabet are automatically compressed by exactly fifty percent when converted from Hexlish characters into binary characters. Although technically lossy, this syntactic compression enables recovery of the correct English letters via syntactic reconstruction. The implementer can predict the size of the compressed binary file and the size of the text that will result from decompression. Generally it is intuitive to recognize English alphabet analogues to Hexlish words. This makes Hexlish a legible alternative to the standard hexadecimal alphabet.

Handbrake 1.9 | Covers video conversion needs on Linux - support for lossless VP9 encoding added 
Lossless? Convert a video while keeping 100% original quality.
What else?
◉Backup your Blu-Ray discs in full
◉Subtitle burn-in improvement
◉Intel QSV VVC hardware video decode support (H.266)
◉Option for AV1 screen content coding (Intel Lunar Lake QSV AV1)
◉Power Save option now pauses the encodes if needed

So my former colleague @jstepien is a brillant engineer / speaker / teacher, but the thing he'll be internet famous for is how websites can't handle his name 
. https://wtf-8.stępień.com is really funny, though.
I'm joining the three 4K webcam views for the month of June into one 3-panel time lapse video. Unfortunately, filter_complex isn't supported with the mac videotoolbox hardware accelerator. So instead of maybe 5-10fps, which would be slow but tolerable, we're encoding at 0.4fps.
It will take about 30 hours to complete on the 2018 iMac (quad core Intel i5 3.4GHz)
I wonder if I can recompile ffmpeg on this thing to enable one of the hardware encoders that could support this filter!

Aaand part 2 is up. A PoC for encoding is ready, but not bulletproof yet.

Alexander W. Janssen’s blog · A PGP Words variant creating natural sentences - part 2This is part 2 of a series of articles I currently writing. In this posting I will define the mapping from a byte to a word for all word types and get the encoder and decoder up and running. For part 1 of the series, go and read A PGP Words variant creating natural sentences - part 1.
Everyone should have a pet-OCD, and my obsession is esoteric encoding schemes. That kept me awake last night, and now I'm giving in.
Part 1 of a handful; from idea to product, I present you "How to convert arbitrary binary data into English sentences and back again."
Part 2 in the making.

Alexander W. Janssen’s blog · A PGP Words variant creating natural sentences - part 1This is part 1 of a series of articles I am planning write. In this part I will outline the problem, and offer a solution proposal and define the requirements.

In April I wrote my third unique cipher, the PentaBit Cipher. This is my first keyed cipher, and my first cipher capable of encoding alphanumeric plaintexts! You read about it, and try it out, over on my site.
