CoreOS seems to be gaining momentum. It happens to be available on Azure so I spun up an instance and tried. Once it’s up, ssh to it and then launch a ubuntu docker instance [bash light=”true”]xpk-core01 ~ # docker run -t -i ubuntu /bin/bash root@cf1c4da1b078:/# root@cf1c4da1b078:/# lsb_release -a No LSB modules are available.

On recent version of Fefora, CentOS, and RHEL, it is possible to use teamd to setup link aggregation. Teamd is more configurable and it allows load balancing on LACP. Here we will walk through the simple configurations using old-fashion config files. To setup load balancing without switch support (or when both connection go to the same…
I’ve been using the previous generation HA-FXT90 ever since it first came out. I was really amazed by JVC when they put together 2 dynamic drivers in a compact chassis. I love the 90 for its deep bass and otherwise balanced sound. The 208SE came out months ago but I only get to read more about…

So I’ve decided to give Microsoft Azure a try. Coming from AWS, it really is difficult to expect another cloud that can be comparative. I’m just going to say that up front.
Got my hands on a DX90 a couple days ago, what a DAP. Its dual Sabre DAC delivers a lot of details in all ranges. From the high to the mid to the bass, I’m getting supreme quality. I don’t think there are emphasis on any range, they’re equally impressive. But as a little bit…
These come in handy as I frequently need to know the time in different timezone. To get the current time in a different timezone, specify the TZ variable [bash] $ TZ=US/Pacific date Thu Jan 8 17:57:08 PST 2015 [/bash] To get the time of your choice [bash] $ date –date=’TZ=”US/Pacific” 01:00′ Fri Jan 9 17:00:00 HKT…
Google likes to reinvent, against what Einstein once said – simple but not simpler. It’s certainly not simpler on the backend but a pleasure for users. Plugins for WordPress are available, why not give it a spin! reCAPTCHA – https://www.google.com/recaptcha/intro/index.html WordPress plugin – https://wordpress.org/plugins/wp-recaptcha
