ingveon Machine Learning in a Year

> "It’s possible to get a good machine learning teacher for around 50 USD per hour"

How/where did you find a teacher like this? Finding a machine learning subject expert is already pretty difficult; knowing how to find one who is also a good teacher would be a useful skill in its own right.

ingveon Thor – A minimalistic operating system in assembly and C++

IncludeOS? [0]

From the CppCon 2016 presentation description:

"Early in the design process we made a hard choice; no C interfaces and no blocking POSIX calls. We’ve done everything from scratch with modern C++ 11/14 - Including device drivers and the complete network stack all the way through ethernet, IP and ARP, up to and including UDP, TCP and recently also an http / REST API framework. To achieve maximum efficiency we decided to do everything event based and async, so there's plenty of opportunities to use lambdas and delegates." [1]

Gah! I really wish the HN submission feature could borrow some ideas from Stack Overflow's duplicate question detection.

(FWIW, the full title is "An Efficiency Comparison of Document Preparation Systems Used in Academic Research and Development", which is too long for HN, so the previous submission also changed it.)

ingveon Chromeos-apk – Run Android APKs on Chrome OS, OS X, Linux and Windows

I'm running Eclipse and the emulator on a 4 year old Mac Pro. Initial startup time for the emulator is about 20 seconds, but after that first hit has been absorbed, it generally takes about 8-10 seconds whenever I run a new build of the app I'm developing. (This is with HAXM [0] enabled. Still far too slow, so pretty much everybody does their development on actual Android devices, but far from the times reported in this thread.)
