The year is 2030.

Computers boot directly into the browser. IDEs are just a web app now, running in the GPU. No one knows why. Or how.

All programs run in 4 nested containers on top of a hypervisor abstracting over the 5 major computational clouds. The last time a branch was predicted correctly, in any CPU anywhere, was 4 years ago.

Cloud costs are withdrawn directly from your retirement fund.

Ext7 just came out, it's written in Javascript and uses AI to guess what the file may contain.

I've done it! After literal months of work, I've finally finished my (rather long) blog post about how AES-GCM works and how it's security guarantees can be completely broken when a nonce is reused:

https://frereit.de/aes_gcm/

It includes more than 10 interactive widgets for you to try out AES-GCM, GHASH and the nonce reuse attack right in your browser! (Powered by #RustLang and #WASM )

If you're interested in #cryptography , #math (or #maths ) or #infosec you might find it interesting.

If you do read it, I'm all ears for feedback and criticism!

Just published age v1.2.0 ✨

Minor release:

• binaries built with Go 1.22.4
• plugin client API
• CLI edge case fixes
• RecipientWithLabels to make auth'd or post-quantum recipients

Very happy about the last point, it was the last hardcoded thing about scrypt recipients.

Deep diving into F5 Secure Vault

Look at that! I got a new domain name.

My latest blog post shares the story of how I got the domain name, including my nerdy teenage dreams, failed OSINT, the "Miniatur Wunderland", and my aunt!

~ Let's make RAM at home, thread #1 ~

In this thread: successful experiment with factory-made ferrite core memory (1 bit for now!), a brief explanation of the experiment, and failed attempts at making a core (so you wouldn't have to try it)

🧵 go~

I became into toy computers after I got my hands on a wonderful Sumikko Gurashi computer (and started to believe that similarly designed machines can be an answer to our cold heartless world).

I have a few vintage vTech precomputers that run BASIC and have decent IO capabilities (a serial or a parallel port at the very least), but I was curious whether newer toy computers has anything similar.

The exhibit we have here is vTech Media Desktop, a toy computer from around 2010. Its original RPP was about $100, but after a short while slashed to $25. The computer has a non-backlit ~64x48 pixel LCD, two mid-sized speakers to play high-quality digital samples and polyphonic MIDI, a membrane keyboard and a ball mouse.

There is a mini-USB port on the back that switches computer into "Sync" mode. The device presents itself as a 16MB USB stick with 512KB free, and mirrors there the contents of 512KB SPI Flash it has on board.

With the right software (which has vanished from the Internet), new apps can be added.
