In-flight messaging I was on a Delta flight the other day, and I was thinking about how they offer free messaging from your smartphone. How do they limit the wifi? Maybe they have some basic filter that says “deny everything except the urls for these 3 messaging apps”, which makes sense conceptually. What if we don’t…
Today, at around 2:30 PM EST, Scripts went down. For most MIT students, this means a few class websites are inaccessible, a few friends' b...

During discussions with my friends and colleagues, whenever the topic of chat protocols comes up, I often remark how simple the Internet Relay Chat (IRC) protocol is and how this simplicity has fostered creativity in the lives of many young computer hobbyists growing up in the late 1990s and early 2000s. For many of…
Update 28.01.16 I found some sites referring to this post. Below are the common complaints I saw, and my replies:
If you ever connected to the Internet before the 2000s, you probably remember how it sounded. But what do these sounds mean?
The Starlink Mini terminal is designed as a compact, all-in-one solution with an integrated Wi-Fi router. While this design is ideal for typical consumer use, certain applications—such as custom networking setups, embedded installations, or power-constrained environments—may benefit from removing the internal router…
Why do you need to place your servers geographically close to your users? One of the reasons is to achieve lower latencies. That makes a lot of sense when you are sending short bursts of data that should be delivered as quickly as possible. But what about large files, such as videos? Surely there is a latency penalty…
This site is now reachable over Tor as a hidden service, at a .onion address that resolves only inside the Tor network. Tor relays and encrypts your traffic as …
A few weeks ago I got curious about an old cable modem sitting in my closet, a Motorola MB7220. Initially I was interested in what kind of hardware it had and if it was running Linux. Some quick searching brought me to a thread on a web forum where people were discussing the built in spectrum analyzer feature used for…
------ Update 03/12/2022 Reuters has published new information on this incident, which initially matches the proposed scenario. You can find...
Let’s lead with the punchline: the question of what comes after IRC, for Mozilla, is now on my desk.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
One of life's minor annoyances is having to wait on my devices to connect to the network after I wake them from sleep. All too often, I'll open the lid on my …
One of the hot features that came with HTTP/2 was PUSH frames. The main idea is that if the server can predict what requests a client might want to make, the server can preemptively send request/response pairs to the client and warm its cache.
BGP is the glue of the internet. For a protocol that was produced on two napkins in 1989 it is both amazing and horrifying that it runs almost all of the ISP to ISP interactions and is now a very fundemental part of the internet.
RDS-TMC uses an encryption algorithm simple enough to be run using pen-and-paper hardware.
Introduction Netcat is a tool that reads and writes data across network connections, using TCP or UDP protocol. Netcat has been referred to as the TCP/IP / networking swiss army knife. In this article we’ll look at different applications of netcat and how it can be useful in day to day activities of a pentester…
What is TCP? This post is an exploration of TCP, the workhorse of the internet. This deep dive includes detailed examples and a step-by-step walkthrough. A simple TCP explanation.
