Microsoft tells devs: Whatever you’re doing in Linux, Windows 10 will soon do it too
“Whatever it is that you normally do on Linux to build an application: whether it’s in Go, in Erlang, in C, whatever you use, please, give it a try on Bash WSL
Microsoft Azure bug put Red Hat instances at risk
The vulnerability was discovered by Irish software engineer Ian Duffy and reported to Microsoft as part of its bug bounty programme. Duffy discovered the glitch while working on a hardened RHEL image for use on both Amazon Web Services (AWS) and Microsoft Azure.
Android security in 2016 is a mess.
if money is no object, my only sound advice can be to buy an iPhone. Apple is still shipping security updates, albeit on iOS 9, for the iPhone 4s which was released in 2011 (5 years ago). The iPhone 5 is still being kept up to date with iOS 10.

Core VLC Developer: ‘Noone Cares About Linux; OpenHMD Is a Joke’
Or also, that noone really cares about Linux. And, also, that we might need direct access to get powerful perf.
jbkempf comments on Core VLC Developer: ‘Noone Cares About Linux; OpenHMD Is a Joke’
Therefore, I have never ever ever said “Noone Cares about Linux”. This is the most stupid thing I’ve ever seen; especially outside of the VR context.

Ubuntu Prepping Its 16.04 “Rolling HWE Kernel”
Ubuntu 16.04.2 and beyond will feature hardware enablement kernels back-ported from newer Ubuntu releases in order to allow new hardware to work on these older LTS releases, but now the Xenial Xerus is switching to a concept of a “rolling HWE kernel.”
You Can Now Package Your Apps as Snaps Without Bundling Their Dependencies
This is possible now because the latest ubuntu-app-platform snap build incorporates the standard Qt 5 libraries, the QML (Qt Meta Language) runtime, the Ubuntu UI (User Interface) toolkit, and their dependencies. The Oxide web engine library based on Chromium and related QML bindings is also bundled in the ubuntu-app-platform snap, so the new Snaps should now be significantly smaller.

New XPS 13 Developer Edition Lands in Europe, United States and Canada | Hacker News
A word of warning: German magazine c’t tests this laptop in its newest issue, using the pre-installed Ubuntu but also with Fedora 25 Workstation Edition (also with a Linux 4.9 development kernel), as well as Windows 10. The results regarding Linux compatibility are pretty bad:
-
The battery lasts for 13h under Linux, which is not too shabby. However, it lasts a whooping 22,5h with Windows 10.
-
The headphone port is very noisy with Linux. No noise whatsoever with Windows.
-
WiFi performance is dismal in Linux. No problem with Windows.
-
The HDMI port on the separately sold docking station does not work correctly with Linux.

DalmatinerDB – A fast distributed metric store
DalmatinerDB’s performance relies heavily on taking advantage of facilities like ARC, ZIL, checksums and volume compression. Expecting those things to be handled on a filesystem level makes it possible to remove most of the code for caching, compression, validation from the application improving code simplicity, stability, and performance significantly.
Essentially the main difference is that it relies on some very well tested software as the foundation. Clustering is a first class citizen and complicated compression and checksumming code is kept out of the database where ZFS can do it instead.
Currently Dalmatiner is a great database if you are looking for a reliable time series metrics store that scales and is 100% open source and not backed by a commercial company.
