Simple trick to increase coverage: Lying to users about signal strength
Poking around in Android the other day I found this nugget in Carrier Config manager ; a flag (KEY_INFLATE_SIGNAL_STRENGTH_BOOL) to always report the signal strength to the user as one bar higher than it really is.

BPS is a GPS alternative that nobody's heard of
I came to the NAB (National Association of Broadcasters) show this year with my Dad to learn more about time in broadcast and live production. I was expecting to learn more about grandmaster clocks, AV sync, timing in protocols like Dante, Livewire, AES67, and more—and I have. But then on the first day here I found…

The Web Is Broken – Botnet Part 2
I guess you have all heard about the growing problem of AI companies trying to aggressively collect whatever data they can get their hands on to train their models. This has caused an explosive surge in web crawlers relentlessly hitting servers big and small. But who runs these crawlers? Turns out — it could be you!

How the “Kim” dump exposed North Korea's credential theft playbook

This actor's operational profile showcases credential-focused intrusions targeting South…

How to modify Starlink Mini to run without the built-in WiFi router
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…

I have at least a few readers for which the sound of a man's voice saying "government cell phone detected" will elicit a palpable reaction. In Department of Energy facilities across the country, incidences of employees accidentally carrying phones into secure areas are reduced through a sort of automated nagging. A…

Get the location of the ISS using DNS
I love DNS esoterica. Weird little things that you can shove in the global directory to be distributed around the world instantly(ish). Domain names, like www.example.com usually resolve to servers. As much as we think of "the cloud" as being some intangible morass of ethereal Turing-machines floating in probability…

NIST was 5 μs off UTC after last week's power cut
If you were 5 microseconds late today, blame it on NIST. Their facility in Boulder Colorado just had its power cut for multiple days. After a backup generator failed, their main ensemble clock lost track of UTC, or Universal Time Coordinated. But even if you used the NTP timing servers they run, they were never off by…

There isn't much point to HTTP/2 past the load balancer
I want to write a post about Pitchfork, explaining where it comes from, why it is like it is, and how I see its future. But before I can get to that, I think I need to share my mental model on a few things, in this case, HTTP/2.

Deliberate Internet Shutdowns
For two days in September, Afghanistan had no internet. No satellite failed; no cable was cut. This was a deliberate outage, mandated by the Taliban government. It followed a more localized shutdown two weeks prior, reportedly instituted “to prevent immoral activities.” No additional explanation was given. The timing…
