Ninjablock to local MQTT server
# This describes how you can connect your ninjablock to your own mqtt server
# It is not the best manual, so please provide feedback
# First of you have to start with the "beta" image found at: https://discuss.ninjablocks.com/t/unstable-brand-new-image-for-your-block/1666
# Or direct link if you must: http://ninjablocks-nightly.s3.amazonaws.com/block/ubuntu_armhf_trusty_sterling_block-unstable_2014-07-16_1044.img.gz
# Then put that on an sdcard (like you normally would)
# Put it in the ninjablock
# Let it boot!!
# power off (upon first boot it creates a ssh key (needed for enabling ssh))
# power on
#!/bin/sh

Profiling an application in Mac OS X

Profiling an application in Mac OS X

Finding which process to profile

If your system is running slowly, perhaps a process is using too much CPU time and won't let other processes run smoothly. To find out which processes are taking up a lot of CPU time, you can use Apple's Activity Monitor.

The CPU pane shows how processes are affecting CPU (processor) activity:

Benchmarking Nginx with Go

Benchmarking Nginx with Go

There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts, load balancing, cache, etc) or can you serve directly from Go? If you need nginx, what is the fastest connection mechanism? This are the kind of questions I'm intended to answer here. The purpose of this benchmark is not to tell that Go is faster or slower than nginx. That would be stupid.

So, these are the different settings we are going to compare:

  • Go HTTP standalone (as the control group)
  • Nginx proxy to Go HTTP
  • Nginx fastcgi to Go TCP FastCGI
  • Nginx fastcgi to Go Unix Socket FastCGI
