If all is well, launch your mysql CLI, and do a "show processlist" to see the open HandlerSocket connections. Now, if you are curious, you can telnet directly to the read or write port and issue some queries , or pick one of the existing clients ( PHP, Java, Python, Node.js, Ruby) and do it from the comfort of your favorite language.

Ruby & HandlerSocket

HandlerSocket ships with a C++ library ( libhsclient ) for which there are …

On paperplanes 21 days ago.

When we set out to build our first product ( Scalarium , now better known as Amazon OpsWorks , we started off with a rookie mistake.

Initially, we played with some ideas to test if we can fit them together. This was mostly focussing on orchestration of servers and their provisioning. We tried out a mix of RabbitMQ, Nanite and Chef (early adopters, yay!)

Back then, NoSQL databases just started appearing, and we thought, screw MySQL, we're going to use something …

Prior to bundler, this is what you would do on snow-leopard to install mysql: $ sudo env ARCHFLAGS= "-arch x86_64" gem install mysql -- --with-mysql- config= /usr/ local /mysql/bin/mysql_config

On Lee Munroe 1 month ago.

Recently I switched my website from Wordpress, hosted on Dreamhost, to Jekyll, which I now host on GitHub. This post is an overview of why, how and any pain points I came across during the migration.

Why switch from Wordpress to Jekyll?

I've been on Wordpress for 7 or 8 years. It's a great tool. However my website is fairly simple . I have 3 pages and a blog. Wordpress is big, it's complex, and runs on PHP with a MySQL database. Jekyll is a light weight static site generator.
