Hi, I'm Iljitsch van Beijnum. Here on iljitsch.com I publish articles and post links about a range of topics.

Also have a look at my business web site inet⁶ consult.

When the BGP table hits 1 million prefixes, will history repeat itself?

On the APNIC blog, Danny Pinto asks What will happen when the routing table hits 1024k? Back in 2014, the IPv4 BGP table reached 512k, a common limit in many routers at the time, and some bad things happened. See my post BGP table hitting 512k limit in older routers. And pretty much the same thing happened in 2008, when the BGP table hit 256k.

I did it again... I made another keyboard tester

The other day I noticed how dirty my VT420 terminal's keyboard was, so I decided to take off the keycaps to clean them.

Then of course it's always good to put the keycaps back where they belong. That's a task made a lot easier with a keyboard tester app such as the online one I made a while ago. However, I don't think the VT420 supports the latest Javascript features...

So I whipped up a command line keyboard tester: kbdtest.php. Save the page, rename to kbdtest.php, then run with ./kbdtest.php. Works on the Mac, haven't tested other systems.

→ Typing my way down the mechanical keyboard rabbit hole with the Drop CTRL

Eight years ago, I wrote Why I use a 20-year-old IBM Model M keyboard for Ars Technica. And now, after a slight (well, five-year) hiatus, I have a new story on Ars, about my new mechanical keyboard.

A new life for the 2003 Apple Wireless Keyboard

Back in 2003, Apple released the Apple Wireless Keyboard:

(Not to be confused with later keyboards of the same name that look like laptop keyboards.)

The keyboard still works with an ancient MacBook Pro, but it won't pair with anything from the 2010s. That's too bad, because I think it looks pretty nice. So I decided to see if I could bring its essence into the 2020s by transplanting the keycaps to my Drop CTRL keyboard.

Review: Cable Matters USB 2.5 Gigabit Ethernet adapter

I think it was in 2016 that 2.5 and 5 Gigabit Ethernet was standardized. After a year or two the first USB to 5GE adapters started to appear at about €/$ 100 and about two years ago the first €/$ 50 2.5GE ones. Right now, there's a ton of USB 2.5GE adapters at good prices.

I got a Cable Matters one for € 31 off of Amazon.
