Yes, I already have a couple of Raspberry Pi, but I had to get one of the new Raspberry Pi 2 (model B), to check out its increased processing power with OpenCV and image processing.
So, lets install it. The Arch Linux install page is here. This new RPi2 has a new ARMv7l Cortex-A7 quad-core! Arch Linux has a new distro page dedicated to it. If you want to install the previous RPi model you can also follow my notes, you just have to get the correct SD image here.

Today almost all of the package delivery companies have a web site where it is possible to track their next delivery. I sometimes order several components or electronic devices over internet and each web shop uses a different delivery company so sometimes its hard to follow all the packages. I recently found this web app that is a life changer: https://www.aftership.com
It is compatible with hundreds of delivery companies and allows you to group all ongoing deliveries in a single page!
You also have the Android app so you can follow your packages using your phone. It is simpler then the web app and you can’t login to your web account so you need to enter again your item track numbers. But if you move a lot its worth it. Hope they improve communication between the Android app and the web app soon.
Here you have a nice how to.
Now this is a great idea! https://www.statuspage.io
A status page that you can use in case your web server is down. Completely independent from your web server so your customers can have some output on any issue you’re having.
I used to have a Firefox plugin that enabled me to get back to the previous tab if I clicked again over the selected tab and this was very practical, as I always have lots of tabs and often go back and forth between two tabs. For example, I have the WordPress and the Yahoo mail tabs pinned and while writing a new post I go to my emails tab and back again to my WordPress tab a few times. If you press <ctrl> TAB you can switch to the next (in GUI sequence) tab, and a <ctrl> <shift> TAB does the opposite. This is the default behavior.
But if you change the browser.ctrlTab.previews config parameter to true then the behavior changes and its a new whole world! You get a tab preview while pressing <ctrl> TAB and the order is no longer the GUI sequence order but the history order! So now I have what I want. And this is really a time saver for anybody who likes to open tabs around with things to read and they tend to accumulate over time.
To do this you need to type in the address bar:
At least the first time you do this you’ll have the warning that you can break your Firefox, go ahead and say you’ll be careful :-)
After clicking the “I’ll be careful” button you get the list of config parameters, to quickly find the browser.ctrlTab.previews parameter just type ctrlTab in the Search text box on top of the page. Then double click on the parameters value to make it toggle to true.
And start a new life using your favorite browser!
