Dispelling Common Cloud Myths

Is there someone in your office that complains constantly yet offers no useful suggestions on how to fix the problem at hand? Do you wonder if some people just thrive on complaining and tickling the skeptic bone in others? Are you sick of the abundance of conflicting and often confusing information? When it comes to […]

Shared Web Hosting Is Not Dead

An old colleague of mine was telling me of his plans to finally, after almost fifteen years of working for someone else, start his own hosting venture. My first instinct was of course to offer this poor soul some Lithium, seeing that his existing salary as CTO is more than triple the amount of profit […]

The Xen Dom-u Kernel And The Kitchen Sink

Does anyone still like configuring and building their own Linux kernels to taste? I do. Call me a nerd, but I actually enjoy spending countless hours slimming down my kernel so it has just enough support for my hardware, with modular support for anything that I might be inclined to plug in. No, the performance […]

Breaking With Conventional Wisdom – Sometimes

In fact, at least in my experience, the only times I have been able to do it ‘correctly from the start’ have been when I start completely from scratch. Most […]

Two years later, we’re still waiting to see what happens to pv_ops in Mainline Linux. Everything else (such as the Xen API, […]

For instance, if you know where to find the running kernel task structure, you can read it while the guest is completely oblivious that you are doing so. In other words, it allows […]

I’ll Leave The Clouds To The Birds

Today marks the third time in one year that I’ve been bitten by someone else’s mistake. I’ve tried several `accounting as a service’ providers and should have learned my lesson after the first bad experience. I appreciate dynamic infrastructure as a service as much as the next person. I love using tools like Xen to […]

Better Productivity With Xen, Ubuntu and XDMCP

Being over-loaded with work is a vicious cycle, especially when the work involves more maintenance than creativity. The cycle goes something like this: 15 things require immediate attention You give immediate attention to 15 things at once Despite the cycle of #1 and #2, #1 still persists at the end of the day Even if […]
