Awesome underwater maps of the Indian Ocean, thanks to MH 370

Geological Insights from Malaysia Airlines Flight MH370 Search

»The tragic disappearance of Malaysia Airlines flight MH370 on 8 March 2014 led to a deep-ocean search effort of unprecedented scale and detail. Between June 2014 and June 2016, geophysical survey teams aboard ships used echo sounding techniques to create state-of-the-art maps of the seafloor […] of the southeastern Indian Ocean.

[…] Previous ocean floor maps in this region had an average spatial resolution (pixel size) of more than 5 square kilometers, but the new maps resolve features smaller than 0.01 square kilometer (an area slightly larger than a soccer field).«

Some time ago, I gave a talk about boring technology at Booking, which means choosing the simplest, stable and maintainable solution you can get away with for solving a problem at a given scale.

Apparently Dan McKinley has similar views, which he explained in Choose Boring Technology. The writeup explains nicely what boring technology is, and why to prefer this.

Never forget your mission, which is business, not technology. The technology is a necessary tool, but likely not your friend.

Zero Days

RAND Corp study about Zero Day exploits is now available. About 200 Zero Days have been analyzed, and data has been collected on how many groups find them, or how long they stay undetected. Among the findings:

  • Zero-day exploits and their underlying vulnerabilities have a rather long average life expectancy (6.9 years). Only 25 percent of vulnerabilities do not survive to 1.51 years, and only 25 percent live more than 9.5 years.
  • For a given stockpile of zero-day vulnerabilities, after a year, approximately 5.7 percent have been publicly discovered and disclosed by another entity.

The reports highlights the importance of things like Google’s Project Zero: Systematically testing software products of all kinds for possible weaknesses and exploitable bugs, then getting them fixed.

“Breitband für alle” nominated for Bertelsmann Award

Breitband für alle provides FTTH in North Friesland, bluer is better

Because FTTH is a problem in Neuland, especially if you are dependent on German Telekom, a lot of people are taking it into their own hands, bypassing German Telekom.

One Organisation doing this is the Inititative “Breitband für alle” in North Friesland, which has been nominated (german) for the “Mein Gutes Beispiel” (My good example) by Bertelsmann. The awards are being passed out on March, 30. Let’s hope they make it (Bertelsmann Page in German)

A book on systemd, that’s what’s missing

Two years ago, I ranted on Google plus that there still is no book on systemd (actually, on systemd + journald + cgroups/namespaces and the assorted things that come with it if you are doing it right).

There are writeups such as various Getting Started articles, and there is collections to the writeups on PID Eins, but there is no book.

A book would be good, though, because it should contain stuff like this.
