WILTW (What I Learned This Week) is a (hopefully) never-ending series of mini-posts, once a week, until the end of time. Terms and holidays apply.


A couple of weeks ago I attended my second UKNOF meeting, this time located in Sheffield over 2 days (you can read about my first experience in London at UKNOF30 here).

It was an interesting format, with the first UK & Ireland Peering forum on the day-1 AM and UKNOF presentations taking up the PM and day-2 AM. It all ended with a pilot of a training workshop (paid workshop mind you), which I didn't attend but I hope went well.

As usual, slides and video recordings are up on the UKNOF website and on their YouTube channel. There's a lot of good stuff to be found, from impressive speeds in the An Update on the Openreach G.fast proof of Concept presentation, to a dizzying ride through Google's Datacentre Networking and a very interesting idea in Using BGP for realtime import and export of spam whitelist/blacklist entries.

There's good work being done by Matthew Walster on best practices for peering, all in one place and in a modern and easy to read format. He's looking for contributors and the source is on github, so if you know a thing or two about peering go take a look!

Last but not least, massive thanks to all the UKNOF chaps who were very supportive of our NOG initiative here in Ireland - I got the opportunity to talk to many people, get advice and even say a few words in front of the whole audience about it!

Updating my Xperia Z3C to 5.1.1

I wrote in the past about Sony's bumpy privacy ride and how to clean up a few dodgy bits from the phone - well that applied to the KitKat flavor of Android. With the upgrade to Lollipop, a few things have changed and the list of blocked apps has grown a bit.

What changed is that instead of using the pm block command to disable some apps via the adb shell you now have to use the pm hide command. It's a weird change as it doesn't seem to be doing as much as the old one did, but nevertheless it works.

I published my full list in a gist on GitHub because it's a bit too long to include in this article. It's taken from multiple posts on the XDA forum and if anything breaks because of this, don't come crying to me, OK? :)

An interview with a pioneer of computing in Romania

This article's in Romanian I'm afraid, but if you can get over that hurdle it's a very good read: about Vasile Baltac, a man who's seen the first computer built in Romania (apparently it was the 8th worldwide, around 1957) and, as a result, the evolution of computing through some very difficult times.

Until next week
