BGP training course at NL-ix in Zoetermeer June 3

NL-ix brings back its famous BGP (Border Gateway Protocol) course. The course is scheduled to happen on 3rd June. It will be conducted by Iljitsch van Beijnum. In one day (09.30 - 16.00) course participants will learn the internals of BGP protocol. This will help them with a much better understanding of their current BGP work.

In English. Hopelijk binnenkort ook weer in het Nederlands.

Upgrading Fiber To The Home to terabit speeds

How movie/TV watching has changed

Back in the 1990s, for a good number of years, I would go to see the "sneak preview" every week. One show a week would be dedicated to showing a movie that hadn't been released yet. And which movie would be a surprise. This meant I ended up seeing all big ticket movies, as well as a good number of additional smaller movies. And with rare exceptions, I would be happy to sit through them.

These days, I very often find myself getting bored with a movie that I'm watching. Now obviously a lot has changed in the intermediate almost 30 years. Have movies gotten worse? I'd say they have. But not so much that this explains me happily watching pretty much any movie in the 1990s vs getting bored by about half of them in the 2020s. Do we have a shorter attention span and more distractions today than we had 30 years ago? Again, yes. But I don't think that's the full explanation.

I think the reason it's so hard to focus on any movie or TV show/episode is that we have so much more choice today...
