If you want to install IBM's DB2 on Ubuntu 11.10, it's fairly straightforward. First, pop over to IBM's DB2 download page and grab whichever format of the DB2 Express-C archive you need. (In my case, it was "Linux 64-bit", which gave me a resulting tarball of
As the next in what might turn into a series on the Git version control system, this post explains what it means to describe Git as a "content tracking" system, a concept that is sometimes a bit difficult for newcomers to wrap their heads around, so let's explain it by way of comparison and a couple trivial Git examples.
Because the Git version control system takes a rather novel approach to how it stores history, I thought I'd write a very quick-and-dirty explanation of that. Once new users understand how this works, a great deal about Git suddenly becomes a lot clearer. So let's see how well this works out. (I'm still touching up this post, so if you see a typo, leave a comment. Or just leave a comment, anyway. And, yes, I can see Drupal is doing silly things with overly long lines; I'm working on that.)
As a favour to a colleague, I recently downloaded and installed the web content management system eZ Publish (the community version) on my Ubuntu 11.04 system. Conveniently, Falko Timme had already documented the process for Ubuntu 7.10 here and, with only a few tweaks to Falko's writeup, the latest version of eZ Publish went in nicely.
Tuesday, May 24 will represent the first after-work meeting of what I'm unofficially calling the downtown Ottawa Linux kernel geek-up. The plan is to meet on a moderately regular basis after work on selected weekdays in downtown Ottawa, and hash out the gory details of some pre-selected feature of the Linux kernel. (NOTE: It's not a general Linux geek-up -- it's specifically for Linux kernel discussion, just to be clear.)
Recently, a number of people have experienced the "black screen of death" boot issue with Linux, based on some problems with integrated Intel video chips. The problem was allegedly resolved but it's managed to crop up again.
If you've been running into that, and have no problem building and booting a new kernel from the source, here's a simple patch you can apply to the source that appears to solve the problem:
--- a/drivers/gpu/drm/i915/intel_opregion.c +++ b/drivers/gpu/drm/i915/intel_opregion.c
Since the online documentation is somewhat hard to come by, this is a short tutorial on how to download and work with source RPM files in CentOS 5.5. And by "work with," I don't necessarily mean compiling and installing; you might simply be interested in examining the source code for one of your CentOS packages, and we'll show you how to do just that.
What's happening here is the step-by-step instructions for how to install the Android emulator on Ubuntu 10.04 in 60 seconds (admittedly not including the ridiculous time it takes to download the various Android platforms you want to support). And so, without further ado, let's get to work.
It's about how to, on your Ubuntu 10.04 system, install VirtualBox, then download and run the spanking new Nuxeo DAM 1.1 digital asset management software in a VirtualBox session. And ... go.
We're aware of the time and budget pressures at most companies, normally accompanied by the plaintive cry from management of, "Yes, I know we need training on that topic, but I just can't afford to send my entire team away for three (or four or five) days to get it!" And that's where we come in.
The main focus at Crashcourse is to offer a choice of intense, 1-day, hands-on courses on specific topics in Linux and open source. And given that we already have the laptops for the delivery of that training, the idea is to show up early, set up a classroom, then spend the day teaching exactly the topic you're interested in. No travel time, and no wasted classroom time.
If we don't already have a course that addresses the topic you're interested in, drop us a note and we'll see what we can do -- our content providers can almost certainly put together a course that's precisely what you're after.
While there are a variety of sources for Linux and open source training, we at Crashcourse are taking a slightly different approach. Our philosophy is simple: exactly the training you want, and no wasted time or travel to get it.
