Xen moves in to Linux Foundation

by Ruchira on April 17, 2013





Xen is the beloved Linux virtualization platform of huge cloud players such as Amazon, Rackspace cloud, Linode etc. Xen was previously a community sponsored project of Citrix. Now Linux Foundation has taken over the development. As written on the official Xen blog

Almost a year ago, I floated the idea within Citrix of finding a non-profit home for the Xen Project. At this point, I had worked for and with the Xen community for just over a year. We only just implemented community-led Governance and it was clear that at some point Xen would need to become a truly vendor neutral project. You cannot imagine how pleased I was, when almost immediately I got full support from Citrix management to pursue the idea of finding a vendor-neutral home for Xen. We looked at various options and it quickly became clear that The Linux Foundation was the most natural fit for the Xen Project. And then the hard work to pull everything together started … but this is a story for some other time. The good news is that as of today, The Xen Project is a Linux Foundation Collaborative Project with an impressive Advisory Board consisting of companies that will contribute to, fund and guide the non-technical aspects of the Xen Project.

SMART data from your hard drives or SSD’s are often valuable to determine the health of the drive and other information such as how many hours it worked.  There are several programs on windows to do this and I have covered about one 2 years ago here https://www.ruchirablog.com/how-to-view-usage-time-of-your-computer/ . There are few SMART data monitoring tools available for Linux such as smartctl but those are command line tools.

I don’t have enough words to express, how much I love Linode. If you search my blog with the keyword “linode” you can find the reviews and rants that I’ve done about them. Linode is beta testing a new feature called Linode “Longview” which provides you beautiful live graphs and information about your virtual machines. Its not limited to linode, you can monitor any external VM’s or Dedicated servers with longview.

If you work in front of the computer quite a lot, You might have eye strain issues. On Laptops this is not a big issue because those have the ability to dim the light considerably. But in my case I use a desktop for work and monitors doesn’t have the ability to dim extensively like laptops.  Even at lowest brightness, the whites are too bright for me.

I’m using Ubuntu and there is this app called “redshift” to adjust the color temperature and lets see how you can get it running.

Redshift adjusts the color temperature according to the position of the sun. A different color temperature is set during night and daytime. During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt.

Lets add the PPA

sudo add-apt-repository ppa:jonls/redshift-ppa

And Install

sudo apt-get update
sudo apt-get install redshift

Server uptime world record

by Ruchira on April 2, 2013



If you are a sysadmin or if you have worked with servers I bet you might have wondered whats the longest uptime a server ever had. Look above, The bar is now set at 6030 days which is about 16 years. Its running Netware v3.12 which is built to share files and printers over the network. Server is nick named INTEL and its owned by a user on arstechnica forums.

Even if the hardware was able to last this much long you might wonder how it survived power outages. Answer is the server was on a financial company backed by central UPS system according to the owner. But finally he has decided to shutdown the server because of complaints about noise it makes.
