Cluster and Grid Comuting

Cluster and grid computing has become extremely popular, yet very few designers are using modern capacity planning techniques to ensure performance.

Grid computing has become extremely popular in IT circles mainly because of the potential computing power and cost savings. But grid computing is a multifaceted technology that means different things to different people.

Some interpret grids to be a heterogeneous group of desktops and servers, which other see it as a group of cluster computers connected together over the internet. Sometimes grids are designed for raw CPU power, others are designed for raw I/O, while others are a combination of data and compute power. Many grids are often designed around a specific set of applications. As we'll see later, this is why grid and cluster design is strongly tied to its intended purpose.

Ubuntu Convergence

  • The Race to Convergence: Or is it a Marathon?
    This article, although it was smart to feature Ubuntu as a forerunner, it foolishly tried to give credit to Microsoft for ‘truly being the first’ to do convergence. First, did they? I had no idea. Nor do I care. Nor does anyone else I roll with. If the name has ‘Microsoft’ in it, we flee for the hills. Why? Because it’s compromised out of the box. It is dangerous.
  • Have We Converged Yet?
    Convergence is not about a unified computing experience across all your devices. Although that's an important goal, convergence is more about that point in time where your philosophy that technology should respect people converges with that of a group or company that believes the same.
  • Ubuntu.com Gets a New Look for the Tablet Section, Rest of Website to Follow
    With the new Ubuntu tablet out the door, Canonical also had to upgrade the website to reflect the changes accordingly, so now ubuntu.com has a really nice section dedicated to the BQ Aquaris M10. If we don't take Android into account, we can't really say that there are successful Linux-based tablet out there. It's not clear why that came to pass, but until this Ubuntu-powered tablet landed, there wasn't much competition. To be fair, there is not much competition right now, since Apple and Google pretty much dominate the market, but BQ Aquaris M10 is the only one that can double down as a regular PC.
  • BQ Ubuntu Tablet Has 64-bit CPU and Will Be Able to Run 32-bit ARM Apps
    The BQ Aquaris M10 Ubuntu tablet is powered by a 64-bit ARM processor, so the users have already started to ask around if they will be able to run the 32-bit apps from the phone on the tablet. The short answer is yes. The long answer is that it will take a little bit of work.
  • What the Ubuntu Convergence Means for Businesses, Consumers, OEMs, and Devs
    As you may well be aware, Canonical and BQ unveiled the world's first Ubuntu Tablet, the BQ Aquaris M10 Ubuntu Edition, which also happens to be the first Ubuntu converged device, which users can transform into a full-fledged PC.

Docker Images Are Moving From Ubuntu To Alpine Linux

Docker is reportedly going to be migrating all of their official images from an Ubuntu base to now using Alpine Linux. Alpine Linux is the lightweight distribution built atop musl libc and BusyBox while using a GrSecurity-enhanced Linux kernel. Alpine Linux uses OpenRC as its init system. If you are unfamiliar with this "Small. Simple. Secure." distribution, you can learn more via AlpineLinux.org. The image for Alpine is a mere 5MB.

Meaning of Convergence, Exploit Excludes Linux

The big news yesterday and even into today was the new Ubuntu tablet, which everyone including Canonical touted as "convergence delivered." Well, today Randall Ross scolds news sites for missing the "timely idea" that is convergence. In other news, security researchers have identified a new exploit that specifically avoids Linux. FOSS Force found that Linux users have no interest in anti-virus software and Phoronix reports on Ubuntu performance over the years. Read more
