Overheard on IRC: Computer Support

Read this today on #lopsa

<kcb> OK, so if you want to know where all your support dollars for computer companies go?..
* kcb has a server. Server started logging a “CPU1 VTT” error the other day.
<kcb> $vendor recommended “reseat the cpu”.
* kcb told vendor “OK, send me some thermal compound, ok?” to which vendor said… sure.

I’m going. Are you?

I will be teaching a full-day class with Marc Staveley on Using Amazon Web Services at this year’s LISA conference. The conference is being held in San Jose, CA from November 8 through 12 and my class (F1) is on the 12th. Come and join the fun!

EC2 Volume Bundling Failure and What Was Really Wrong

A virtual computer in Amazon’s EC2 service, called an instance, has an ephemeral existence. They are created as needed but when they are stopped they disappear. This comes as no surprise to those of us who work with virtualization on a regular basis, but it can be a bit of a shock to the administrator…

Updating Rubygems: a necessary step before installing the Amazon gem

This article shows you how to install a gem (a ruby package) that provides access to Amazon APIs for EC2, ELB, and RDS. But along the way it also provides important information on the entire Rubygems environment. This information is critical for anyone who is tasked with maintaining a working Ruby environment.

Yesterday I posted an entry about using Ruby to access the Amazon EC2 API and I mentioned a gem that provided the classes needed to make such access easy. Gem is the package system for ruby, and fills a role similar to one that CPAN provides for perl. The Amazon gem is called amazon-ec2 and it is written and supported by Glenn Rempe. Continue reading

Using Ruby with Amazon Web Services, an example

I’ve been recently extolling the virtues of Ruby on the Lopsa IRC channel so I thought it would be fun to take a real world problem and write a Ruby-based solution. This particular problem has to do with manipulating snapshots in Amazon’s EC2. Those who administer EC2 instances know (or should know) that the storage…

The Display of Percent CPU in top

The single most important piece of information processed by top is the
measure of a process’s percentage cpu utilization, known as percent
. Although top is perfectly capable of display and sorting on a
variety of information, by default it sorts by percent cpu. The
reason for this is that most people use top to find out what the cpu
is doing, or more specifically which process is hogging the cpu.
Percent cpu readily reveals this information.

Blogging about Top

When someone at a conference discovered that I was the original author for the utility “top” the reaction is always the same: “hey that’s a really cool program”, “thanks for writing it”, or “top really saved the day”. I am glad that in my own little way I was able to contribute to the system…

Join us at LISA ’06

Now is the time to start thinking about the annual LISA conference. This year the conference will be held in Washington DC at the Wardman Park Marriott Hotel. The conference runs from December 3 through 8. I am especially proud of this year’s conference. I think we have a fine collection of speakers and papers this year, and I look forward to being your host. If you want to read more about the planning and work that is going in to LISA 06, please visit the conference blog here:
