5 February 2009 - 6:35pmMore Subversion

A few months back I posted briefly about how I set up a Subversion server on an Ubuntu virtual machine.  That virtual machine was set up using Virtual Box which I’ve since decided is sort of a pain to use.  As a result, I uninstalled Virtual Box and removed all of the VMs created under it (losing the Subversion server in the process).

For COMM 444 I had to create a Fedora VM for “learning” on.  I decided to give VMWare Server a try and have been mostly impressed with the quality of it.  Setting up a Fedora installation was pretty painless and it runs so well on my machine that I’ve been using it to do schoolwork and such on (as opposed to using polaris, which has some annoyances).  Today in class, Tino mentioned that if we were responsible developers we would probably be using some sort of version control system while we write our compiler.  That way, when we finish building a piece of it and get it all working, we’ll always have the code at that particular moment so that next week when we break it beyond repair (or accidentally delete everything) we can go back to the way it was.

So I took his advice and spent some time after class getting a Subversion server set up in the Fedora VM I already have set up.  To get it going, I used this article on the COSI wiki and this post on my blog (which references a few other articles).  I should note that using the version of WebSVN from their site (as opposed to the one available in the Ubuntu repository) means that the sweet theme I worked so hard to find last time I set this up is included as the default.

There is still one fairly obvious issue and that’s the fact that, though I’m committing all my changes to SVN, they’re not really being backed up to some other location.  Both my working copy and the SVN revisioned one are on the same hard drive.  That means that if my computer bites the dust, I’ve still lost everything I worked on.  I’ll be trying to figure out some form of backups soon, but until then at least I have revisioning under control.

14 January 2009 - 3:11pmBoring

, ,

Operating Systems is boring.  So I figured I’d write a blog post.

My schedule for this semester is slightly different than I’d originally planned for.  Instead of taking CS464 (Game Development), I’ve decided to drop that and take COSI for 2 credits.  The grouping situation for the project in CS464 wasn’t going to work out well for me and since I don’t need that class I decided I’d be better off not having to worry about it.

For COSI, I’m going to be working on a few different projects.  So far, I’ve started working with Ryan and Zach on setting up and testing a storage technology called DRBD.  I don’t know too much about it yet, but we’re thinking it may be a good solution for the storage configuration in the server room.  More information to come as we learn more about what its capable of and how well it works.  Beyond that, there are a few possibilities for other things to work on, but nothing solid yet.

I guess that’s all for the moment.  I’ll attempt to keep this more up to date this semester.

6 November 2008 - 11:51pmClasses

So my schedule for this coming semester (my last one!) is all set.  It goes as follows:

  • COMM 444 (Unix Web Administration) – MW 4:00-5:15
  • CS 444 (Operating Systems) – MWF 2:00-2:50
  • CS 445 (Compilers) – TTh 9:30-10:45
  • CS 452 (Computer Graphics) – TTh 1:00-2:15
  • CS 464 (Game Development) – TTh 8:00-9:15

I think it looks pretty good (aside from the 8am class on Tuesdays and Thursdays).

1 October 2008 - 11:05pmMainframes

, , ,

So today I completed parts 1 and 2 of the IBM Master the Mainframe Competition.  All total it took me about 4 hours to complete.  I’m hoping I got all of the part 2 answers right and that I finished within the first 60 (the prize is $100).  Some of the content was completely different than last year’s, but about half of it was pretty much the same as it was last year (too bad I didn’t take time to document the exact procedures from last year).

Since I’m not at school this semester while I do my co-op, I’m thinking I may take time to work on part 3.  The five people to have accumulated the most points in part 3 tasks by December 29 win an MSI Wind Laptop running Linux (the top two of those five get a trip to the Mainframe lab in Poughkeepsie, NY).  A laptop would be a sweet prize so I figure it might be worth the effort to work on part 3 (not to mention the fact that I’ll probably learn a lot from it).

26 September 2008 - 5:01pmSubversion and other things

, , , ,

It’s been a long time.  I’ll try to give updates on as many things as I can think of in no particular order:

Wedding:

Nothing much new here.  Joelle and I continue to brainstorm about miscellaneous pieces of the wedding, but we haven’t made any concrete plans in quite some time.  Keep an eye out on our wedding blog for updates as they come.

Subversion:

Tonight I decided to tackle the task of installing and configuring Subversion with Apache and WebSVN.  I would have liked to do it using the Apache installation on my Windows computer, but alas, Windows sucks (I would never pay money for it).  As a second option, I turned to an Ubuntu virtual machine created using VirtualBox (which I can run all the time thanks to my recently upgraded 4GB of RAM).  Installation of Subversion is really easy, it’s the following configuration of Apache and WebSVN that was the tough part.  I used a combination of this guide, this guide and finally found this template for WebSVN that looks excellent.  I now have a working Subversion repository where I can store any projects I decide to work on (something anyone working on a development project should probably be doing).

Work:

Work’s been alright lately.  I’ve had some interesting tasks involving VB scripts to look at (one was an Excel macro that I wrote, one was updating a script that queries Active Directory).  I’ve also been working on some documentation here and there.

School:

I looked at classes for next semester today.  My tentative course load looks like this:

  • CS 444 – Operating Systems
  • CS 445 – Compiler Design
  • COMM 444 – Unix Web Administration
  • CS 464 – Game Development (?)
  • EC 350 – Microeconomics (?)

I’m not completely sure about the last two yet.  CS 464 may not actually be offered since it’s pending approval right now and I don’t really know if I want to take Microeconomics or not.  I’ll probably end up doing at least one, if not both, of them.

That’s about all I can come up with at this point.  Hopefully I’ll start posting more often again.

24 July 2008 - 9:19amWP-SpamFree at last

,

For the last few weeks I’ve been getting 15-25 spam comments per day on my blog.  I have had Akismet installed since the beginning, but I was getting tired of having to clear the queue on a daily basis. I went looking for a better option and found the WP-SpamFree plugin. WP-SpamFree uses some complicated JavaScript and who knows what else to make it very difficult for a spambot to post a comment (I haven’t looked at the source and the description of how it works was very vague). As I understand it, the plugin can’t possibly block a real human from posting, since the logic used only affects bots (because of this, all spam comments are just deleted, there’s no queue to sift through). Since this is a “front-end” spam blocker, you have to deactivate any other “front-end” spam blockers, such as captchas, but you can leave “back-end” spam blockers, such as Akismet, active (though the plugin’s author says it won’t be necessary). So far, the plugin has blocked about 10 spam comments and nothing has slipped through to Akismet.

In addition to WP-SpamFree, I also installed WP Super Cache and AJAXed WordPress. WP Super Cache adds caching functionality to WordPress to reduce the load on the server when pages are requested (by creating static HTML pages to serve up instead). So far it’s working quite well. AJAXed WordPress adds some awesome AJAX to WordPress if you have the time to modify your theme to accomodate it (there’s only like two things active out of the box, the rest require theme modification). I haven’t had time to play with it yet, but there’s a lot of potential.

23 July 2008 - 3:34pmSweet!

, , ,

I was looking at my site’s stats on my Google Analytics account today and I noticed three referrals from a URL I’d never heard of before. Drilling deeper into the report revealed that the referring URL was the “plugins.php” page of this person’s blog. Still not understanding what was going on, I went to this person’s blog and poked around a little and then it hit me… the author of http://burkeism.com/blog is using my Google Calendar Feed Parser plugin! Woo!

What a good feeling it was to see someone actually employing my code on their own website. If you are a Google Calendar Feed Parser user, please leave a comment and let me know. And, if you’re the author of burkeism.com, leave me a comment and let me know how it’s worked for you. And, if you’re a user and you really like my plugin, link to it on your blog so others can find it too!

Edit: Further perusal of my Analytics reports revealed more users of my plugin! I’m psyched. In addition to these referrals from other blog’s “plugins.php” (which are a result of someone clicking on my name in their WP admin panel), I’ve also had 150 referrals from the WordPress Plugins site and my plugin has been downloaded 93 times. Also, a simple search for my plugin (or any derivative thereof, including “google calendar feed”) on Google gets you to my plugin from the first page of results (a search for the exact title “Google Calendar Feed Parser” yields the number one result!).
