A thorough review of a major cloud outage.
We can argue that we are out-of-scope for the UK’s Online Safety Act.
I should have titled this post “I hate S3”. 📢 What is the status quo? FTP is dead (yay), SFTP is too dependent on SSH and unix authentication. AWS made S3 pervasive and now every webapp that needs to store files assumes you’ll be able to connect it S3. This …

Four years after my post on doing network captures on macOS with Process ID, Wireshark 4.6.0 has been released which includes support for parsing this…
This post could’ve been titled “Nostr vs ATProto”, but that really isn’t what I wanted to do here. While I will be comparing and contrasting them a lot, and that’s kind of even the point of writing this, I didn’t want to really pit the two against each other at all, and especially not with the title. I also want to…
I’ve used Mullvad as my VPN provider for a few years. Their service is good, they provide keys for 5 devices, rely on the Wireguard protocol, and offer alternative configurations as well. Despite that, my needs have changed and I wanted to be able to have granular control over DNS queries and the ability to connect my…
A Git collaboration platform, built on AT Protocol
It is common knowledge among Wi-Fi professionals that using 20 MHz or 40 MHz channel widths when planning 5 GHz networks offers the best overall ex
1 Prologue A while ago, I took a flight from Canada back to Hong Kong - about 12 hours in total with Air Canada. Interestingly, the plane actually had WiFi: However, the WiFi had restrictions.

It's normal for post-quantum cryptography to be rolled out as an extra layer of security on top of traditional pre-quantum cryptography, rather than as a replacement .

I recently migrated my self-hosted services from a VPS (virtual private server) at a remote data center to a physical server at home. This change was motivated by wanting to be in control of the hardware and network where said services run, while trying to keep things as simple as possible. What follows is a…
From handles to hosting.
We are excited to announce a significant advancement in the security of the Signal Protocol: the introduction of the Sparse Post Quantum Ratchet (SPQR). This new ratchet enhances the Signal Protocol’s resilience against future quantum computing threats while maintaining our existing security guar...
"Where are you?" is not an easy question to answer on the Internet. The telephone system's address plan embedded a certain amount of physical location information in the fixed line network, and a full E.164 telephone number indicated your location in terms of your country, and your area within that country.
