Hi, I'm Iljitsch van Beijnum. This page has all posts about all subjects.

→ America is not the land of the free but one of monopolies so predatory they imperil the nation

Excellent piece by Observer/Guardian columnist Will Hutton based on the work of economist Thomas Philippon:

The news is that over the last 20 years per capita EU incomes have grown by 25% while the US’s have grown 21%

And:

The US economy is becoming increasingly harmed by ever less competition, with fewer and fewer companies dominating sector after sector – from airlines to mobile phones.

Because:

But why has this happened now? Philippon has a deadly answer. A US political campaign costs 50 times more than one in Europe in terms of money spent for every vote cast. [...] Corporations want a return on their money, and the payback is protection from any kind of regulation, investigation or anti-monopoly policy that might strike at their ever-growing market power.

A real eye-opener.

For instance, there have been instances where spammers grab an unused prefix, start announcing it in BGP, do a spam run and then drop the prefix. When packets with private addresses enter your network, bad things may happen if you use those addresses yourself. And these invalid "martian" packets are just an annoyance, using up traffic and generating log entries.

Europe runs out of IPv4 addresses even further, what now?

Less than three months ago I wrote about how the uptake of the remaining IPv4 addresses at RIPE was accelerating, with the RIPE NCC likely to run out of the addresses set aside in the "last /8" before the end of the year. And so they did, two days ago. So as of this week, it's no longer possible to request address space in the RIPE service region (Europe, former Soviet Union, Middle East) and get them within a somewhat predictable period...

Airpods Pro

It's insane. I already spent nearly 800 euros on bluetooth headphones this year. And then Apple released the Airpods Pro, costing € 279 here in the Netherlands. And I couldn't help myself and bought a pair. So let's see how they compare...
