/* Use of lambda functions for fff custom_fake
* this file contains an example of how to have "nested functions"
* within a test case for setting an fff custom_fake for pass by reference args
* This method for custom fakes allows all your test code to be self contained
* inside a test case instead of having global functions cluttering your test
* code.
* note that lambda captures are not supported

fnv1_32 and fnv1a_32 in rust
// see libhashkit/ from memcached
// Just using this as excuse to test out the Rust lang
// be warned on correctness, completeness, etc
// Should match libhashkit
// should also match
// FNV hash'es lifted from Dustin Sallings work

atomic writes linux c++, QT, Boost, GNU
// Practical snippets for loosely atomic writes on linux
// Important, even more so on allocate on flush file systems such as xfs and ext4.
// You can learn more here:
// These snippets are not perfect, if writing cross platform applications - marco guards
// Just trying to convey the gist
// The basic routine is:
// 1. Write data as

Figure out OSM road lengths
This is an example tool that computes the sums of highway lengths.

notes from Charter Chapman:
I picked this up in 2015 and it didn't work :( so hammered it until it worked
You need the latest of the old Osmium

# I had a problem today where trying to load things into an Xvfb was not working because the xvfb
# was not yet initialized. The problem script is as follows:
# Start the Xvfb on DISPLAY :1,
`dirname $0`/Xvfb :1 -screen 0 1280x1024x24 -ac -br -fbdir /dev/shm & xvfbpid=$!
DISPLAY=:1 xli -onroot -fillscreen `dirname $0`/images/background.png
# The only solution I see on the web is to insert a sleep statement.
# I don't much like that. The solution I came up with is to wait for the display to be ready to use via xdpyinfo.

fnv1a_32 hash in javascript consistent w/ libhashkit
