What's the difference between a word and byte?
...ster size). The most common word sizes encountered today are 8, 16, 32 and 64 bits, but other sizes are possible. For examples, there were a few 36 bit machines, or even 12 bit machines.
The byte is the smallest addressable unit for a CPU. If you want to set/clear single bits, you first need to fet...
Where does Vagrant download its .box files to?
...n the atlas. For example,
https://atlas.hashicorp.com/ubuntu/boxes/trusty64/versions/20150530.0.1
Replace the domain name with vagrantcloud.com. So https://atlas.hashicorp.com/ubuntu/boxes/trusty64/versions/20150530.0.1

How to Calculate Execution Time of a Code Snippet in C++
...
You can use this function I wrote. You call GetTimeMs64(), and it returns the number of milliseconds elapsed since the unix epoch using the system clock - the just like time(NULL), except in milliseconds.
It works on both windows and linux; it is thread safe.
Note that the gr...
Is there a faster/shorter way to initialize variables in a Rust struct?
... a new type that implements a default value of -1 and use that instead of i64 in your struct. (I haven't tested that, but it should work).
However, I'd suggest to slightly change your data structure and use Option<i64> instead of i64. I don't know the context of your code, but it looks like y...

Taking Guillaume's solution a little further:

{
switch (Type.GetTypeCode(o.GetType()))
{
