Introduction to Vagrant – Part 1

Dec 022013

If you work in IT it’s pretty normal in these days to have a computer with at least 4GB of RAM and if you have bought it in the last year probably it has 8GB, this is fantastic to run modern applications that usually require much more RAM than in the past, but this make the use of Virtual Machine on personal computer much more easy and doable.

This open some interesting options in the development cycle of any application or service as now it’s possible to have a development/test machine on every personal computer, as system administrator I’d like that these VM should be as much similar as possible to the production environment, so what’s a good way to manage and distribute Virtual Machines to the developers ?

For what I’ve found around the best answer at the moment it’s: Vagrant.
In this first part I’ll cover the theorical aspect of Vagrant and in the next one I’ll show you some basic command to setup a running environment with it.

Screencloud – Easily Capture and share your Linux desktop

Screencloud is an app that allows you to capture screen under Linux , Mac or Windows and automatically upload the screenshot to an FTP/SFTP server of your choice or a provider in the cloud such as Dropbox, Ubuntu One, Imgur or a cloud service proposed by Screencloud themselves.

Once the file is sent, your clipboard will contain the link to the image.
This could be a good way to quickly share a screen capture without having to do the multiple steps (take/save/change it/upload somewhere/copy the url) that usually you should do to share a simple image.

The software is released under GPL-2.0 and the sources are on github.

Original article first published in Spanish on http://vidagnu.blogspot.it/

Yesterday I ran into a problem in a SWAP partition on an Astaro Command Center, so I decided to restart with an Ubuntu CD, and my first attempt to repair the system was with the fsck command, but when trying to use it I got the message fsck.swap: command not found

So I check with the badblocks command that the partition had no bad blocks.

sudo badblocks -v /dev/sda2

The above command did not return any error, then searching the Internet I found this simple way to rebuild a damaged swap partition.

arkOS: build your Cloud with a Raspberry Pi

Recently I’ve discovered this project that has great ambitions:

arkOS is an open-source platform for securely self-hosting your online life.

Everything started from the founder Jacob Cook and the CitizenWeb Project he founded. It’s designed to run on a Raspberry Pi – a super-low-cost single board computer – and ultimately will let users, even of the non-technical variety, run from within their homes email, social networking, storage and other services that are increasingly getting shunted out into the cloud, and so under the control of big companies.

So in short arkOS is a lightweight Linux-based operating system that runs on a Raspberry Pi.

It allows you to easily host your own website, email, “cloud” and more, all within arm’s reach. It does this by interfacing with existing software and allowing the user to easily update and change settings with a graphical interface. No more need to depend on external cloud services, which can be insecure “walled gardens” that require you to give up control over your data.

arkOS will have several different components that come together to make a seamless self-hosting experience possible on your Raspberry Pi. Each of these components will work with each other out-of-the-box, allowing you to host your websites, email, social networking accounts, cloud services, and many other things from your arkOS node.
