Well, as of sometime on December 5th a huge number of the archivists that were scrambling to rescue archives from Yahoo Groups, had their {e-mail addresses} apparently banned so they can no longer…
I’m sharing the story of a bad situation I had ordering a new phone through Google Fi. It turned into a two month long ordeal where the service got worse and worse. At every turn the Google Fi team was presented with a chance to make things better and every time they blew it. I’m sharing this because I hope a long…
Up until recently, it was a pain to defend againt WPA2 brute-force attacks by using a random 63-character password (the maximum in WPA-Personal ) mode). Thanks to Android 10 and iOS 11 supporting reading WiFi passwords from a QR code, this is finally a practical defense.
Looking at a dataset of 350 million ssl connections inspires some initial questions:
How many web servers are running on your machine right now? Do all of those development web servers have a secure login, and restrictive CORS permissions? You don’t know? Allow me to check for you:
The network stack does several seemingly-impossible things. It does reliable transmission over our unreliable networks, usually without any detectable hiccups. It adapts smoothly to network congestion. It provides addressing to billions of active nodes. It routes packets around damaged network infrastructure…
Motivation For a moderately security conscious geek like myself, there can be a number of reasons to want to set up a home VPN server: Accessing your home computer via screen sharing without exposing it to the Internet (and thereby to potential evil-doers). Accessing servers with IP white lists (common case for…
On 26 Nov 2019 at 14:55 UTC, I logged into my server that hosts my website to perform a simple maintenance activity. Merely three minutes later, at 14:58 UTC, the domain name susam.in used to host this website was transferred to another registrant without any authorisation by me or without any notification sent to me…
Last November I went to an IETF meeting for the first time. The IETF is an interesting place; it seems to be about 1/3 maintenance grunt wo...
This article was discussed on Hacker News ( later ), on reddit ( also ), featured in BSD Now 294 . Also check out this Endlessh analysis .
Disclaimer: I’m not a network engineer and never have been - a tame network engineer has been consulted to ensure factual and terminological accuracy. The following is an in-exhaustive run down of everything I’ve learnt from building and using network infrastructure on Amazon Web Services. If you find you have no…

A very long article about commercial VPNs, their marketing strategies, and the truth behind their privacy and security claims.
TL;DR: - Mail is not hard: people keep repeating that because they read it, not because they tried it - Big Mailer Corps are quite happy with that myth, it keeps their userbase growing - Big Mailer Corps control a large percentage of the e-mail address space which is good for none of us - It's ok that people have…
In one of my last experiments I replaced my crappy T-Mobile (now Magenta) 4G modem/access point with an OpenWRT-based cheap travel router and a 4G USB LTE modem. That doubled my speed over the wireless (WLAN) network but the setup was limited by the outdated and under-powered travel rooter. So I got myself a cheap…
Let’s lead with the punchline: the question of what comes after IRC, for Mozilla, is now on my desk.
At Monday’s WWDC conference, Apple announced a cool new feature called “Find My”. Unlike Apple’s “Find my iPhone”, which uses cellular communication and the lost…
Let's Encrypt have announced that on July 8th, 2019 they will begin issuing new certificates from their own intermediate CA and not their current cross-signed intermediate. Here's what that means and what action, if any, site operators need to take…
Yesterday I had the idea that it would be cool if I turned a Nintendo Switch (will be referred to as NX to avoid confusion as NX is the code name for the Nintendo Switch ) console into an actual network switch. I thought about it a bit and realized that it would be doable in hardware at least, since the NX docking…

With the new year upon us, I decided it was time to do something ambitious for my Open Source project. This is where I normally quip about never mentioning my project before, even though I literall…
Every developer should know the basics of DNS, the critical protocol at the heart of the web.
