Today the Wordfence developers announced the new fastorslow.com tool, a handy tool for seeing how fast your site is in various parts of the world. The Wordfence folks build a quite useful plugin used by many sites – and this one – to keep reduce risk of attack.
This new tool however can be used to see the performance of any type of public site and recommendations on speeding it up. It also would be a much easier way to time requests to a server like in the World Network Requests Measurement post.

In Ian Stewart’s book, Professor Stewart’s Casbook of Mathematical Mysteries, he writes about an easy way one might prove that the earth is not flat. His “easy” proof can be done by booking some flights and timing them… or, simply looking up actual flights from certain cities to other cities. If it is much much shorter for a certain flight from A to D while A to B to C to D in a nearly straight line is much longer, it’s effectively a proof you can go around the world without falling off…

There are numerous howtos for Raspberry Pi and other portable computer voice applications, like this one, but generally they are using Google’s voice api. This may work… when the wifi or network is working, but not only is this sending your voice to google, it requires payment for usage over a certain amount. Users of your robotic application may be not so thrilled when they see it is sending audio samples to Google, and that it does not even work if there is a wifi hiccup! Instead, let’s go through a simple on-device installation that works fairly accurately with no external dependencies!

Laravel is a widely used, useful web app framework to use, but one thing you may notice is it can be a bit complex to set up on production server. I recently set up a small webapp I had been working on for Amateur radio operators (hearham.com), and there are several steps that are not so well documented. If you self host or host on Amazon or Digital Ocean these steps should help you to also get a simple webapp up and running:
