Happy New Documentation!
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
How I Relearned the Consequences of Improper Monitoring
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
Show 322: Can We Put An End To Stupid Network Tricks?
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.
Keeping the Cisco CCDE exam secure !
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 […]

Worth Reading: the Mythical Man-Month
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.

OPML-to-Markdown Conversion Script
In this post, I’d like to share a script I wrote to help with converting Outline Processor Markup Language (OPML) documents to Markdown. If you read the recent update on my Linux migration plans, you may recall that I identified OPML files (created in OmniOutliner) as an area where some work was going to be required. This script is the result of my efforts in this area.
<aside>Before I continue, I want to very briefly point out that this script was written to help in my specific use case. It’s quite likely that you’ll want or need to adjust the behaviors of this script in order to meet the needs of your particular use case.</aside>
This script takes advantage of two tools: pandoc and sed. pandoc is a third-party tool that is easily installed on Ubuntu using apt or apt-get. (I haven’t checked other Linux distributions, but I suspect packages are available there as well.) pandoc is also available for OS X, making it a very handy cross-platform tool to have in my toolchest. (See this post for more information on how you can use pandoc in a Markdown-heavy environment.) sed, of course, is a Continue reading
Book Report: Machete Season
Overview
Jean Hatzfeld’s Machete Season: the Killers in Rwanda Speak is a much different book than the Pol Pot history that I covered a couple of weeks ago. It’s harder to write about, because it’s just what the title describes: the killers in their own words, interspersed with short contextual explanations of the events surrounding the Rwandan genocide.
Hatzfeld – who has also written two books about the horrific Baltic wars of the 1990s – argues that many of what the mainstream media call genocides should be described as war crimes instead: brutal, unacceptable mass killings of defenseless humans that nonetheless take place in the the context of reducing a population’s ability to wage war. Genocide, he argues, is a term that should be reserved to describe an effort to completely exterminate a population and leave it incapable of ever recovering. In the Rwandan genocide, for example, the Hutu killers often preferred to murder women and children first, because it would leave the Tutsi population less capable of carrying on to the next generation.
History
Modern Rwanda has three main ethnic groups: the majority Hutu, the minority Tutsi, and a small population of Twa jungle-dwelling hunter-gatherers. At the time of Continue reading
Looking Ahead To The Next Platforms That Will Define 2017
The old Chinese saying, “May you live in interesting times,” is supposed to be a curse, uttered perhaps with a wry smile and a glint in the eye. But it is also, we think, a blessing, particularly in an IT sector that could use some constructive change.
Considering how much change the tech market, and therefore the companies, governments, and educational institutions of the world, have had to endure in the past three decades – and the accelerating pace of change over that period – you might be thinking it would be good to take a breather, to coast for …
