Economy Size Geek - Organizing a Library
Now that I was able to add books to all three applications, I wanted to see how hard it was to add additional sources for lookup. GCstar ships with a number of sources. The application itself does not let you add or configure any of the sources, so your only option is to pick which one to use. The process of adding a book was straightforward. You just click Add and then put in the information. I am not sure if the problem was with authentication or something else, but the tool never found anything using Amazon as a source. I was able to pull up information about my books using ISBNdb.com. Once GCstar finds a book, the system pulls in a lot of details, including the book cover. There also is a field for storing the book's location. It is just a free-text field, so I would have to come up with my own way of encoding location. You can search by location, but there is no way to sort by it or store the search, so you can't browse the shelves based on where they are, which ends up being useful in my library, as I keep books on the same topic clumped together.
GCstar does not have any support for a scanner; however, it does have a number of different options for importing data. It even can import an Alexandria collection. One way to get the data into the system is to put the ISBN numbers into a CSV file, and GCStar then can import that CSV. Once the data is loaded, you have to go to each book to trigger the lookup in the remote repository.
Alexandria allowed me to add my Amazon credentials. It also supports adding in custom Z39.50 sources. Tellico had the most extensive list of options for adding additional sources. It included support for Z39.50 as well as GCstar plugins.
One of the problems I run into with my library is that even if I remember I have a book, I don't remember where it is. Recently, I moved a large chunk of my technical books to my office, making the situation even worse, so I want to be able to track books' locations.
Alexandria does not have any concept of location baked in. It does support tags, which would allow me to enter a tag to give me a better idea about a book's location (for example, Home:Cabinet 1:Shelf 3). The search allows me to search by tags, so I could see other things on the same shelf, which would be useful because I tend to put books on the same subject next to each other.
GCstar 1.3.2 had a field for location. The newer 1.5 version has replaced that with support for tags. Once the books were tagged, I could browse the books by grouping them by tags. The search function did not support tags, so I couldn't limit my searches to books only at home or only at my office.
Tellico had the most advanced features for this part. I actually could add specific fields for library, cabinet and shelf. Then, I could use those fields for grouping and searching.
All this searching and sorting is useful, but I saved the most important consideration for last. How do I get all my books into the system? The first option is simply to type in the ISBN of all my books. If your library is small enough that you are willing to do this, you probably don't need a system to track your books.
The next option is a barcode scanner. I happen to have a Flic Bluetooth barcode scanner from a previous project, and I was fortunate enough to find a great guide to getting it working under Linux (see Resources). Once everything was set up, I was able to scan the ISBNs from all the books quickly into a text file.
I tried to import the ISBNs into Tellico, but each time, it crashed on the import. I wasn't able to confirm whether this was a problem with the program or the way I installed it.
GCstar was able to import the list of ISBNs with no problem. The annoying part of that process was that once the books were imported, it did not do any lookup on the ISBN. I had to go to each book individually to tell it to download the data. Once I did, I got the book cover and everything else.
Alexandria got it right. Not only did it do the import, but it also downloaded the information about the books.
I realize that not everyone has a barcode scanner lying around. Don't worry; you have other options. If you have a Webcam, you can install ZBar. This barcode-scanning software turns your Webcam into a barcode scanner. I was able to get the same list of barcodes from ZBar that I got from my barcode scanner. The only downside is that I had to bring each book to the camera. It's a lot cheaper, but not nearly as convenient if you are scanning in a lot of books.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
