The oVirt Project is pleased to announce the availability of all-new principal documentation for the oVirt 4.0 branch.
There are many people out there who are content to use software without documentation, preferring to muddle through the software based on past experience with similar software or just the desire to put the software through its paces.
We all do this; I could not tell you the last time I looked at documentation for Firefox or Chrome, because I've been using browsers for over 20 years and seriously, what else is there to learn? Until I learn about a cool new feature from a friend or a web site.
In a software community project, one of the biggest things a community must do is to provide proper onboarding to the project's result. This means:
Explaining what the software is
Providing a clear path to getting the software
Demonstrating how to use the software
All three of these onboarding requirements must be done right in order for onboarding to work successfully. Documenation, then, fulfills the third requirement: showing how software can be used. Not every one will need it, but for those users who do need it, it is very nice Continue reading
I had just lost the RAID array that hosts my ESXi data store. I didn’t yet know that’s what had happened, but with some investigation, some embarrassment, and a bit of swearing, I would find out that an oversight on my part three years ago would lead to this happening.
I first realized there was trouble when every VM on the host became unresponsive. Most notably, the Plex Media Server fell off the network which caused the episode of Modern Family that we were watching to immediately freeze. What was odd to me is that while the VMs were unreachable, the ESXi host itself was fine. I could ping it, ssh to it and load it up with the vSphere client. The first wave of panic hit me when I found messages like this in the host’s event log:
This was quickly confirmed from the ssh shell by looking for the data store and finding that a) the symlink for the volume (RAID1) pointed to a non-existent directory and b) the reported size of the volume was a paltry 450MB compared to the 930GB I expected.
Since I knew from prior experience Continue reading
Engineers are often compelled to do stupid network tricks to overcome application design issues. These tricks introduce fragility and dont fix underlying problems. Can we stop? The post Show 322: Can We Put An End To Stupid Network Tricks? appeared first on Packet Pushers.
One of the most important thing about CCDE exam is security. We all think that it is secure, it is not cheatable. There is no CCDE dump. We all believe that. CCDE exam has been around for more than 8 years and there are still only less than 400 people in the world. It seems […]

I was discussing a totally unrelated topic with Terry Slattery when he mentioned a quote from the Mythical Man-Month. It got me curious, I started exploring and found out I can get the book as part of my Safari subscription.
