Effective February 1, 2024 there will be a charge of $0.005 per IP per hour for all public IPv4 addresses, whether attached to a service or not (there is already a charge for public IPv4 addresses you allocate in your account but don’t attach to […]

Free Public WiFi
Once, many years ago, I stayed on the 62nd floor of the Westin Peachtree Plaza in Atlanta, Georgia. This was in the age when the price of a hotel room was directly correlated with the price of the WiFi service, and as a high school student I was not prepared to pay in excess of $15 a day for the internet. As I…

VyOS From Scratch – Edition 1 (set up your own router)
As a VyOS evangelist, maintainer, and more, I’ve been meaning to write a simple series of “how-to” guides for VyOS for a while. Sure, there are plenty of guides out there, but I think a lot of them fall short in demonstrating WHY you are entering specific commands.

Underwater ears everywhere
Programming note: the subscribe link was broken for a while because I am bad at computers (yet another case of "forgot to enable the systemd unit"). It's fixed now. The unsubscribe link was also broken and is now fixed but, you know, maybe that was a feature. Did wonders for reader retention.

The FCC responds to my ATSC 3 encryption complaint – they want to hear from you
The FCC reached out to me and is asking all of you who signed the petition to also file a comment in their docketing system for the ATSC 3 petition. This is very easy to do and will just take a few minutes. So far there are only about a dozen or so complaints filed. … Continue reading The FCC Responds to my ATSC 3…

HTTP vs. WebSockets: Which one is the fastest for Postgres queries at the edge?
Faster is always better, especially when executing SQL queries. We recently introduced SQL-over-HTTP to our driver, which previously only supported WebSockets. Why did we do that?

ProtonMail Rewrites Your Emails
I switched to ProtonMail a few years back after getting fed up with Google. It’s been mostly acceptable, but a few months ago the Android client started mangling emails – if I hit “send” too soon, it would send out only part of what I’d typed; I had to wait 10 seconds or so after I finished typing before hitting send…

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…

All IP addresses are equal? “Dot-zero” addresses are less equal (2013)
In theory, all IP addresses are the same, and you can allocate them at random without a problem. 192.168.1.2 is certainly not better or worse than 192.168.1.15, right? But, in practice, certain IP addresses are regarded as "special" by some implementations and do not yield the same user experience.…
