Ubuntu store apps won’t work across mobile and desktop in 14.04

Filed under
Ubuntu

One of Canonical's main goals in bringing Ubuntu to mobile devices is to create a converged platform across smartphones, tablets, and PCs. As such, a developer should be able to write an app that has a single code base yet runs on all three types of devices, presenting a different interface to the user on each form factor.

Technically, this has already been achieved. Ubuntu Community Manager Jono Bacon this week showed off Karma Machine, a reddit client built by a third-party developer using the Ubuntu SDK:

Ubuntu 12.04.4 LTS Performance Benchmarks

Filed under
Ubuntu

The benchmarks in this article are some straightforward tests done on the same HP EliteBook (Intel Core i5 2520M, 4GB RAM, Intel 160GB SSD, HD Graphics 3000) when comparing clean installs of Ubuntu 12.04.2, 12.04.3, and 12.04.4. Unfortunately the mirrors of the original Ubuntu 12.04 LTS release and the first point release have vanished, so the testing was limited to these three past point releases for the Linux distribution that originally shipped in 2012 and will be maintained through 2017.

Security Leftovers

  • How To Improve The Linux System’s Security Using Firejail
    As you already know, Linux kernel is secure by default. But, it doesn’t mean that the softwares on the Linux system are completely secure. Say for example, there is a possibility that any add-ons on your web browser may cause some serious security issues. While doing financial transactions over internet, some key logger may be active in browser which you are not aware of. Even though, we can’t completely give the bullet-proof security to our Linux box, we still can add an extra pinch of security using an application called Firejail. It is a security utility which can sandbox any such application and let it to run in a controlled environment. To put this simply, Firejail is a SUID (Set owner User ID up on execution) program that reduces the risk of security breaches by restricting the running environment of untrusted applications.

Containers vs. Zones vs. Jails vs. VMs

  • Setting the Record Straight: containers vs. Zones vs. Jails vs. VMs
    I’m tired of having the same conversation over and over again with people so I figured I would put it into a blog post. Many people ask me if I have tried or what I think of Solaris Zones / BSD Jails. The answer is simply: I have tried them and I definitely like them. The conversation then heads towards them telling me how Zones and Jails are far superior to containers and that I should basically just give up with Linux containers and use VMs. Which to be honest is a bit forward to someone who has spent a large portion of her career working with containers and trying to make containers more secure. Here is what I tell them:
  • [Old] Hadoop Has Failed Us, Tech Experts Say

    The Hadoop community has so far failed to account for the poor performance and high complexity of Hadoop, Johnson says. “The Hadoop ecosystem is still basically in the hands of a small number of experts,” he says. “If you have that power and you’ve learned know how to use these tools and you’re programmer, then this thing is super powerful. But there aren’t a lot of those people. I’ve read all these things how we need another million data scientists in the world, which I think means our tools aren’t very good.”
