The new .zip TLD is going to cause some problems
Many years ago, Google applied for the .zip Top Level Domain. ICANN, in its infinite wisdom, granted it. And now, I think, bad things are going to happen. You see computers try to be helpful. They see you wrote "visit example.com" and autolink the thing which looks like a domain name. That's handy - especially as most…

Graviton 3, Apple M2 and Qualcomm 8cx 3rd gen: a URL parsing benchmark
Whenever you enter a URL into a system, it must be parsed and validated. It is a surprisingly challenging task: it may require hundreds of nanoseconds and possibly over a thousand cycles to parse a typical URL. We can use URL parsing as a reasonable benchmark of a system performance. Of course, no single measure ……

It's TCP vs. RPC All over Again
We’ve written previously about the fact that the Internet seems to be missing a standard protocol for the request/response paradigm, with repeated attempts to force-fit TCP leading to inevitable mismatches. Sometimes we feel that we are the only people who think this way, with our networking

SirTunnel, a personal ngrok alternative
From time to time I need to expose a development web site or web service to the world. In the past, I’ve used ngrok for that, and of course long ago I built ReverseHTTP which is somewhere in the same ballpark, but I recently got fed up with the state of affairs and decided to see whether there was something simple I…

ARM vs. Intel on Amazon’s Cloud: A URL Parsing Benchmark
Twitter user opdroid1234 remarked that they are getting more performance out of the ARM nodes than out of the Intel nodes on Amazon's cloud (AWS). I found previously that the Graviton 3 processors had less bandwidth than comparable Intel systems. However, I have not done much in terms of raw compute power. The Intel…

Netheads vs. bellheads redux: the strange victory of SIP over the telephone
How much do you know about how the PSTN (that is, the public telephone network) works? At some point long long ago, it was signalled using in-band frequencies, which facilitated the infamous phreaking using so-called “blue boxes”. This led to a switch to out of band signalling, ultimately culminating in something…

International domain names: where does https://meßagefactory.ca lead you?
Originally, the domain part of a web address was all ASCII (so no accents, no emojis, no Chinese characters). This was extended a long time ago thanks to something called internationalized domain name (IDN). Today, in theory, you can use any Unicode character you like as part of a domain name, including emojis…
