I’ll sit down in the next couple of weeks and make some real posts, but just wanted to get back into the blogosphere after such a long absence.

So onto the actual install of the hard drives. I received the box from Newegg the beginning of last week. I’m assuming Newegg receives their drives in styrofoam packing with 8 drives per set, as my box contained the styrofoam with 4 drives in it. Unfortunately, I forgot that OEM drives do not come with mounting hardware, so a trip to Unicorn Electronics was necessary to get the mounting screws. After I had all of the parts, installing the drives was a matter of removing the slot loading trays and securing each drive. After that, I simply had to reload the trays and the drives were good to go. I’ll get into the software more in the next post, but I’ll touch on the formatting of the drives quickly now. After the drives were installed and I booted the system up, I formatted each drive and created a software based RAID1 configuration using GEOM Mirror, which is part of FreeNAS by default. Because RAID1 only allows 2 drives to be used at a time, at least for the software based instance I’m using, I set up 2 RAID1 configurations, one for Data and the other for Backups. The drives are shared on the network via SMB and AFP shares, based on what I plan on using them for.

So, like I said at the beginning of the post, the hardware was a quick and easy process. Since I’ve got the drives installed, I’ve been playing with getting the software tweaked properly for the past 2 weeks almost. Once it’s all working properly, I’ll outline how everything is set up in the next post.

$query = "
	SELECT p.*, IFNULL((votes.vote_count_up - votes.vote_count_down),0) as PostVote
	FROM $wpdb->posts as p
	LEFT JOIN `wp_up_down_post_vote_totals` as votes
		ON p.ID = votes.post_id
	WHERE p.ID IN (SELECT tr.`object_id`
		FROM $wpdb->term_relationships as tr
		WHERE tr.`term_taxonomy_id` = '##')
		AND p.post_status = 'publish' 
		AND p.post_type = 'post'
	ORDER BY PostVote DESC
";
$posts = $wpdb->get_results($query, OBJECT);

Line 1:
p is aliased as the posts table – all of the post information is returned from here. PostVote is the total of up and down votes for each post from the wp_up_down_post_vote_totals, aliased as votes. IFNULL() is used in the event that a post has no vote data stored in the table, and avoids having a NULL result returned. This is also necessary for ordering the results.

Line 2:
Set up the alias and determine which table is being queried.

Line 3-4:
In order to not lose any posts that don’t have any vote information, a LEFT JOIN is used to select all of the posts. This line allows the vote totals to be returned properly.

Line 6-8:
Since only one category needs to be queried, this line makes sure that all of the posts are part of the appropriate category. IN is used as an array of Object-ID’s are returned containing all of the posts in the selected category. Replace ‘##” with the taxonomy_id, not the category ID, of the appropriate category.

Line 9-10:
The last part of the WHERE clause is to ensure that the posts returned are of the ‘post’ type and have been published already.

Line 11:
Finally, the posts are ordered by the PostVote, to ensure that the highest voted posts are at the top.

I hope this is helpful to anyone who was in the same position as me. Any questions, leave a comment below.

And, without any further ado, my current GeekTool setup:

For the most part, it’s almost identical to what I was using on my last MBP. The major changes are (1) ToDo.txt, (2) GCal, and (3) iTunes. I know that I had iTunes embedded on my desktop in the last post, but with Lion now out, the program I was using did not behave the way I was hoping it would. I’ve since switched to a completely GeekTool related way of handling iTunes information. As was the case last time, some of these scripts are not my own – I’ve tried my best to give credit where I can, but if there are any problems, please leave a comment.

ToDo.txt

Header: echo "ToDo's"
ToDo.txt (Local Copy Only): /path/to/todo.sh
ToDo.txt (Web Synchronized): /path/to/unison todo.prf -silent -auto -batch; sed -i.bak 's/\\//g' /path/to/todo.txt; /path/to/todo.sh

I’ve written about ToDo.txt before, and included some screenshots of how I was embedding it on the desktop. If you only use ToDo.txt on one computer, embedding it on the desktop is as simple as executing the shell script, as shown in the second line above. If you want to synchronize your todo list between your computer and a remote server, you’ll need a copy of unison installed on both systems. In the last line of code above, the first statement synchronizes the text files between both systems, the second statement handles some formatting to ensure everything displays properly, and the last statement prints it out on the desktop. For those who are interested in the web interface, I will try my best to do a write up on it once I’m back at school and settle in.

Calendar

Header: echo "Calendar"
Calendar Script: Download and change the extension to ‘.pl’
Calendar Script Execution: perl ~/Desktop/Perl/gcal.pl

There really isnt much to say about the Calendar script – it pulls upcoming events from your Google Calendar and allows you to display them on your desktop. If you want to read more about how the script handles it, head over the author’s post for all the details.

iTunes

Click to Enlarge

iTunes Script: Download and change the extension to ‘.scpt’
iTunes Script Execution: osascript /path/to/iTunesInfo.scpt

As with the Calendar, a simple script is used to display the album information. The only real drawback from CoverStream is that, due to the refresh rate in GeekTool, this geeklet doesn’t operate in real time. That is, if you change a song, it might take a few seconds for your desktop to update with the new information. Check out the original author’s post for some more information on how the script works.

I know there aren’t as many geeklets as last time, but with all of them combined, my desktop has become much more functional. The ability to see my calendar and todo’s without having to open any additional programs is a huge time saver. As always, any questions, please don’t hesitate to post a comment below.

Anyway, the two main components I decided to leave stock were the hard drive and RAM (if you couldn’t tell already). The RAM I quickly found on Newegg for $30 – it was a G.Skill kit (which happens to be my personal go to brand for RAM) at the same speed as the stock RAM in MBP. By quickly found, I mean the 8 GB of RAM was installed within 3 hours of bringing the computer home. As for the hard drive, I thought I would be able to handle the switch from the SSD in my old MBP to a 7200 RPM drive in the new computer, but quickly came to realize that the speed difference is HUGE. Last week I found a 256 GB Samsung 830 Series on Newegg for $350 – if that sounds a little high to anyone, Apple charges $500 for the 256 GB SSD option, and, again, they keep the original hard drive. After debating if I should just get it already or wait a little longer, I ended up buying it. One interesting thing to note is that the hard drive that came in the computer was 9 mm tall, while the SSD was only 7 mm – there’s no issue using a smaller drive in the MBP, but I was definitely surprised when I placed the drives side by side. Here’s a picture of the SSD fully installed.

After upgrading the RAM and swapping out the HDD for an SSD, the computer is insanely fast. Not to say it was a slouch before – the quad core i7 is definitely a huge improvement over the Core 2 Duo that was in my old MBP – but the difference between a traditional hard drive and a solid state drive is staggering. The computer is virtually quiet during normal operation, and only audible when the fans kick on if its working a little harder than normal. Overall, I’m loving my new MBP – its amazing how much of a difference 4 years makes in the computer world.

Check out the screenshots below, and check back in the next few weeks – I’m hoping to clean up some of my modifications to the web-wrapper and repackage it for others to use. I only made a few changes with regard to security and formatting the output, but I think they’ll be helpful so that someone else doesn’t have to worry about. Any questions, leave a comment below.

GeekTool:

ToDo.txt via the Web

Update [1/6/2012]: It seems that the organization behind ToDo.txt realized that they needed official iOS support and recently released their own native client. You can check it out here. I havent bought it yet (the $1.99 seems a little steep for what its actually doing), but from reading the reviews of it, you need to keep your todo file in your dropbox; not as clean a solution as I was hoping they would come out with, but probably offers a little more functionality than my web interface.

1. Download and install Cookies Manager+ for Firefox. Restart to complete the installation.
2. Open ‘Cookies Manager+’ and enter ‘PREF’ in the search bar.
3. Under sites, find the cookie for ‘google.com’ – the name of the cookie should be ‘PREF’
4. Double click the cookie to edit it. Change the ‘Content’ to ‘ID=03fd476a699d6487:U=88e8716486ff1e5d:FF=0:LD=en:CR=2:TM=1322688084:LM=1322688085:S=McEsyvcXKMiVfGds’
5. Reload any Google site (Gmail/Calendar/+/etc) and you should have the new Google Bar enabled.

Its a nice change from the toolbar approach Google was using before – everything is contained in a single drop down menu from the Google logo. Make sure to check out my friends blog (TheTechUpload.com) for some more interesting tricks and hacks.

I started by designing a simple layout that was aesthetically pleasing, and added in the basic functionality: register a new account and login to the system. Given that it was supposed to be a movie rental portal, I next had to figure out where to get a decent sized movie library that I could store in my database. After some thinking and googling, I decided to use IMDBs Top 250 as a starting point. I originally thought of writing a scraper from scratch to obtain the relevant information, but quickly found out that IMDB API was freely available. However, in order to use IMDB API, I needed to have the movie list stored somewhere; either in the database or as a text file. A little more googling led me to ScraperWiki, where I found a scraper that was already written to dump the Top 250 into a .CSV file. After uploading the .CSV file to my server, I put together a quick PHP script to parse it out and save the IMDB IDs into a table. Now I was in business – another quick script to run the IDs through IMDB API and I had a working movie database. I also ended up saving the movie posters from IMDB locally on my server to avoid hotlinking them every time the page was loaded. After getting the movies all put together, I started building out the rest of the functionality: rent/buy movies, checkout, request a new title, view/return rentals, view purchases, and view transaction history. To reduce the amount of reloads the user would have when navigating the site, I ended up linking almost all of the operations to AJAX requests that queried PHP scripts and updated the DOM using jQuery.

Some of the other fun features that stand include:

• Facebook/Google+ like notifications for when items are in the cart or rentals are overdue.
• A ‘Quick Cart’ dropdown that appears when the notification for the Shopping Cart is clicked.
• A few CSS3 hacks to create a wrapping effect around the body of the page.
• Embedded Trailers when viewing the details of a single movie.
• A scrolling interface for the movies page that allows the user to view all of the movies in the catalog without reloading the page
• “Employee” reviews of movies, with a 5-star rating system.
• The ability to request a new movie, or vote for a movie requested by another customer.
• Similar Movies (when on a Movie detail page) and Suggestions calculated on the fly based off of the genre of the current movie or previous transactions, respectively.

I’m sure I left a few things out – I’ve been working on the site for about 3 weeks now, so I know what I’m expecting to see at this point. Overall, it was a fun project to work on, and it allowed me to test out some new features that I probably wouldn’t have had the time to on a real production site. Anyway, you can check out the working prototype here – just register an account and start playing around with it. Any questions or comments, leave me a post below.
