Debian installer on a USB key with a writable file system.

I couldn't find a concise article about creating a Debian installer USB 
key with a writable file system, so here is my take.  This assumes you 
have an available Linux system.  Note that some old BIOSes might not 
happily boot USB drives created in this way.

* Install the packages syslinux dosfstools mbr
* Insert the thumb drive and find the device using dmesg 
* Install a Master Boot Record to the drive (install-mbr /dev/sdX)

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".

Demonstrates combining Qt and tornado, both which want to have their own event loop.
The solution is to run tornado in a thread, the issue is that callbacks will then also be executed in this thread, and Qt doesn't like that.
To fix this, I show how to use execute the callback in the main thread, using a Qt signal/event in combination with Promises.

The output of the program is:
fetch page, we are in thread <_MainThread(MainThread, started 47200787479520)>
response is 191548 bytes, we are in thread <Thread(Thread-1, started daemon 47201018689280)>
the other thread should fulfil the result to this promise, we are in thread <Thread(Thread-1, started daemon 47201018689280)>

require 'nn'

input = torch.DoubleTensor{4} --input word index
target = torch.DoubleTensor{6,5,4,2} --target word indices. So we have 1 true context ("6") and 3 negative contexts ("5,4,2")
label = torch.DoubleTensor({1,0,0,0}) --the first label is true sample, rest are neg samples

model1 = nn.Sequential()
model1:add(nn.LookupTable(1000,4)) -- word embedding layer, vocab size is 1000 and each word is 50 dimensional
model2 = nn.Sequential()
model2:add(nn.LookupTable(1000,4)) -- context embedding layer, this will be dot producted with an element of the word embedding layer
