MySQL Compat

Published on Wednesday, November 15, 2006

I've run into this error quite a few times, might as well toss blog entry about it:
ERROR 1064 at line 17: You have an error in your SQL syntax near 'ENGINE=MyISAM DEFAULT CHARSET=latin1' at line 7
One likely reason this comes about is because the data being imported/exported is not compatible with the database version. For instance, at home you export the information from a mysql5 database. Then you try to import it on a mysql3.23 database somewhere else -- and it craps out on you. Bummer.
The solution is quite simple:

 mysqldump --compatible=mysql323 -u root -p database > exportName.sql

MCSE: Security

Published on Wednesday, November 8, 2006

Status: Done!

My buddy Ian and myself have decided to get our MCSEs. However, Ian is a Mac lover, and I can't seem to stay away from Linux (and I'm too cheap right now to buy a MacBook). The irony might be subtle, yet we are still studying and making progress. For the most part, I have decided to take the tests in the following order:

70-290, Security+, 70-270, 70-291, 70-293, 70-294, 70-298, 70-299

Update: So, now I'm MCSE. I'm still debating whether or not to do the final Security test. I really need to get caught up with Exchange, so I might do the Messaging test at some point, but who knows. At this point I'm calling it good.

Resize a Xen Image

Published on

So, you've got a few Xen images around, and they are starting to fill up. How do you add a few more gigs to 'em?

 root@tpe:/# xm shutdown vm01
root@tpe:/# cd /xenimages
root@tpe:/xenimages# dd if=/dev/zero bs=1024 count=1000000 >> vm01.img
root@tpe:/path/to/images# resize2fs -f vm01.img
That's it, you just added a gig to your image called 'vm01.img'.

Katapult Screencast

Published on Friday, November 3, 2006

Ian keeps bugging me at how great Quicksilver is. Knowning that there must be an alternative built for linux, I accidently stumbled across Katapult.

While it still has a little room to grow, Katapult makes a great tool in any KDE toolchest. Press ALT+SPACE, and your widget fires up, ready to take your orders. Since words don't really do this justice, I created a screencast.

Xen + nVidia

Published on Thursday, November 2, 2006

Status: Done!

I've played with quite a bit of virtualization, especially VMWare for ages. About eight months ago I started to play around with Xen, and got it to work great, except for the fact that the nvidia driver wouldn't work with the Xen kernel. That said, I'm gonna give another go.

Throughout senior high, and especially my last year, I managed to score a bunch of crappy motherboards and random parts and pieces. Six or so years later, my parents are still finding old motherboards. Considering these computers were mainly P120s with 64-128 megs of RAM, they weren't so hot. What is one to do?

As you could guess, when I started university I had quite a few computers in my room. I had about three or so P120s (one in a hampster cage, don't ask), one AMD600, an AMD1ghz and one iBook (500 whooping mhz). Computers would die, get replaced, but overall they worked quite well. Considering almost all the computers ran Linux (the AMD1ghz also ran Windows -- to play games -- and the iBook sort of ran OSX -- and YDL), every system was quite happy. I had an OpenBSD box as my gateway. Life was good.

But now I don't like having five+ systems. Electricity alone is a strong factor, plus, I don't really want to manage all those systems. Plus noise.

Because of this, I have two systems: my workstation/test lab, and my laptop. I hopefully will never need anything more. But, because of thise, I needed Xen to play nice with my Nvidia closed source driver -- which when I tested it eight months or so ago, it wasn't. Since then I have been using Linux-Vserver, and while it works great, my requirements have started to change.

Luckily Nvidia has released a few new updates, and a few hackers have patched the driver to include support for a xen-based kernel. Maybe I'll write up a tutorial at some point.

Since I've already done the creation of the doms before, and it is somewhat similar to Vserver, everything went smoothly. You can expect some fun screencasts and experiments in the near future.
