This post is going to be a bit different from my usual posts. It’s still about computers, but it’s about a different type of computer: the computer modules in my 2009 Dodge Ram 1500 pickup. Vehicles these days have lots of computers in them. I’ve historically been afraid to mess too much with them in fear of screwing…
This year we invited Vint Cerf to tell the story.
Late last year, I started experiencing some unusual intermittent connection issues on my Desktop. In general, I had a stable connection with average latency; however, at (seemingly) random times throughout the week, I would start experiencing sudden 2000ms+ latency spikes every couple of seconds.

My main computer is a MacBook Pro from 2017, but I have some servers laying around and one other laptop connected at home with ArchLinux installed that I use mainly for development. I connect to it remotely either directly using a SSH/Mosh + Tmux + Emacs/Vim combination, or using the pretty convenient VSCode Remote…
Since I joined Charm, I’ve been working and learning more about SSH, and I thought I would share a few quick tips and tricks with you.
We are excited to announce that PGPP (Pretty Good Phone Privacy) is now in Beta.
Like many of you, I've got hardware on my desk that's sending UDP packets, and the time has come to take a closer look at them.
The InterPlanetary File System (IPFS) is according to the Wikipedia description: "a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system.". It works a little like bittorrent and you typically access content on it using a very long hash in an ipfs:// URL…
Back in 1996, the website TotalNews.com had a brilliantly evil idea. Why not make a single website that itself contained all the top American news websites, directly embedded within?
Yesterday, August 8, 2022, Twilio shared that they’d been compromised by a targeted phishing attack. Around the same time as Twilio was attacked, we saw an attack with very similar characteristics also targeting Cloudflare’s employees
gRPC comes up occasionally on the Orange Site , often with a redress of grievences in the comment section. One of the major complaints people have with gRPC is that it requires HTTP trailers. This one misstep has caused so much heartache and trouble, I think it probably is the reason gRPC failed to achieve its goal…
Cybersecurity researcher, entrepreneur, and engineer.
I wanted to write a post and do a bit of a deepdive into ICMP, ping and traceroute. I’ve found that having a good networking foundation has been a tremendous…
Everybody knows a DNS response needs to fit into a 512 byte UDP packet, right? But suppose it doesn't fit...
Back in the old days, I could just type route (or, later, ip route) in my Linux terminal and get an accurate picture of all my routes. This is no longer the case.

This section is an introduction to TCP/IP programming using a sockets API. (Sockets can also be used to work with other network protocols, such as IPX/SPX and Appletalk, but that is beyond the scope of this document.) The standard socket API was originally developed in the Unix world, but has been ported to OS/400 as…
As part of my new job, I'm learning a lot more about the mysteries of the Domain Name System than any mortal should know I thought possible. The humble unix dig command allows you to query all sort of DNS information. For example, to see name server records for the BBC website, you can run: dig bbc.co.uk NS Which will…

We have expanded our DNS blocking service with Gambling and Adult content filters!
On my home network I have guest WiFi configured and when guests come round they need to know the password. Happily there's a way to make thi...
A design pattern to reduce centralized control and change incentives in social networks.
Despite being designed and operated as a decentralized network-of-networks, the Internet is continuously subjected to forces that encourage centralization. This document offers a definition of centralization, explains why it is undesirable, identifies different types of it, catalogues limitations of common approaches…
