I'm not really knowledgeable about UC, but I'd like to read some early drafts, if possible!

💥💥💥💥💥 age v1.3.0 💥💥💥💥💥

Post-quantum keys, seeking DecryptReaderAt API, age-inspect CLI tool, built-in recipients compatible with hardware plugins, non-interactive passphrase input, Go framework for implementing plugins, and sooooo many improved errors.

Six years to the day after the first beta!

Building a Transparent Keyserver We apply a transparency log to a centralized keyserver step-by-step, in less than 500 lines, with privacy protections, anti-poisoning, and witness cosigning.

Using an age keyserver as a demo, this article demonstrates how to add a transparency log to a centralized service step-by-step.

We use Tessera for the tlog, VRFs for privacy, and the Witness Network. It all takes just 500 lines to integrate!

The result of years of work making tlogs accessible.

A photo of me standing on a sunlit brick walkway, wearing a black suit and white shirt, smiling, and topped with a laurel graduation wreath. I am holding a bouquet (blue hydrangeas and red roses) and a red diploma folder. In the background are grass, trees, a streetlight, and parked cars.

Hand holding a dark red hardbound master's thesis against a plain white wall, with gold-embossed logos and text on its cover. At the top, the cover shows Università degli Studi di Padova and Dipartimento di Matematica logos. In the middle, the title reads "Fuzzy Searchable Symmetric Encryption: Design and Implementation of a Novel Scheme Toward Real-World Applications." Below the title is written "Master Candidate: Simone Ragusa", "Supervisor: Prof. Nicola Laurenti", and "Academic Year 2024/2025".

One month ago, I earned my master's degree in cybersecurity. Working on my thesis was deeply rewarding, and I received a final grade that exceeded any expectations I had when I began this journey two years ago.

Thank you to all the great people who make cryptography open and welcoming to anyone.

Some CSS is failing (overlapping texts) on mobile, portrait mode.

The automatic removal of imports bothers me too at times. Though, you can change the default behavior by completely disabling imports organization on save if you like that option. See github.com/golang/tools....

The materials are wonderful, and the fact that they are CC-licensed is fantastic. I'm currently writing my master's thesis and have already found myself looking at your slides multiple times to recall some definitions and concepts. So, thank you!

I wish you a successful course (I'm sure it will be!) and hope you have a lot of fun teaching it.

I assume that the course is only for AUB students, is that right? In any case, thank you for making the materials publicly accessible, they are great!

I'd say yellow/amber

I love it! I also found out about it very recently. Here's the archive URL for the high-res image if anyone is interested: archive.org/details/unix...

That (presumably) has a meaning too! See groups.google.com/g/comp.unix....

Do you need some testing? I use GrapheneOS on my main device. Happy to help if needed!

It's really not bad. Though I think it gets rather ugly as soon as you try to be too clever with it (as is often the case with many other things).

Happy birthday, Filippo! 🥳 I'll send you some words. ✍🏻

Yes! I have one or two of those fairies at home!

Yep! ✋🏻

That would be great! I already handle crypto/rand errors on Read with a panic, so in my case nothing would change except writing less code, which is great since it also renders it impossible to forget handling the error in the first place.

Update: indeed, audio works on desktop! Anyway, strange YouTube behavior, I'd say!

Huh, interesting! I tried four different apps on mobile (also setting different resolutions, which should affect the audio format AFAIK) and the audio didn't work on any of them. I'll try from my computer tomorrow!

Is it just me or is the audio completely broken? I can barely hear some noises at max volume.

Ah, yes! I missed the point you were actually making earlier. I'm sorry!

The QR icon appeared to me only _after_ setting a username. 🤔

Me too, five!

Avril Lavigne fights a bear shark on the set of the music video for her song "Rock n Roll".

What a throwback!

Uh, I feel the pain.

Thanks for sharing the advice, I'll try that way!

I'm a bit jealous of this, I'd love to actually start writing blog posts, but I never know where to start and I'm afraid of writing poorly (which is definitely in contrast with my perfectionism)
