Gizmodo just ran a piece how some websites would skew their online prices depending on where you live. Of course, this is entirely possible based on info they already have about you, when you log in with your account info. Wireless providers have been doing this for years, presenting different types of phones and services based on the zip code provided. Shipping rates have also varied based on location. That’s understandable, but online prices being different based on where you live is bit discriminatory. I wonder if you can fool the system by logging into different web proxy servers with IP addresses that are registered in different parts of the country. Anyhow, interesting stuff.

I was recording audio on Audacity the other day when Windows crashed unexpectedly. I never had a chance to save the recording. When Windows rebooted, the audio recording were all there, but they were all broken up in smaller files. As it turned out, they were over 100 .au files under the unsaved Audacity folder. The question is how do you piece the files together.
There’s a Linux sound utility called “SoX” that runs across multiple platforms, Windows, Linux, MacOS X, that converts various formats of computer audio files into other formats. SoX can play and record audio files as well. To recover the unsaved Audacity recording, I went to the Audacity folder and executed the following statement from the command line.
sox *.au combined.au
Essentially, the sox command you see above concatenates multiple files into one big file called combined.au. After that, I created a new Audacity project and imported the combined big file into the new project. I then saved the new project. Once saved, I can then export the project to a MP3 format.
If you ever need to recover from a crashed Audacity project, you can use the sox command to recover a project.
One item you can really get for a deep discount at eBay is a smart phone charger. A typical smart phone charger at any of the major wireless providers, will cost consumers anywhere from $20-30 dollars. You can find a similar one at eBay for about a third of the price, with no sales tax, and that includes shipping.
If you’re not pressed for time, you can also get one, for a slightly cheaper price, from a vendor from China. Typically, it takes 3-5 weeks for items to arrive from China. I prefer to buy items from U.S. vendors, since the items arrive sooner, and majority of the time, the quality is good.
There’s no guarantee, however, what type of quality product you’ll get from an international order. I typically pay just a bit more from vendors with good reputation, where product quality is not going to be a question. Anyways, a Droid charger at for under $9 bucks is a steal. It beats shelling out for $30 at any of the wireless stores.
I bought a Mac Mini a month ago. I love it. The only gripe I have is I wished I had a better monitor. But, that’s not the Mac mini’s fault. Lately, I have been thinking about swapping my Mac Mini with the new, cool, sleek, 21 inch iMac. How is that possible? There’s a holiday promotional right now from October 27 until January 7. Any computers bought within this window can be returned or exchanged. Typically, it’s only a two week return policy.
So, I’m debating whether to swap units. The Mac mini that I bought actually has a faster processor than the low end iMac. The Mac mini has a 2.3GHz quad-core Intel Core i7 processor, while the iMac runs on the 2.7Ghz Intel Core i5 processor. As far as upgrades, the Mac Mini is a lot easier to mod. You can add easily more memory, a second hard drive or SSD to the unit without much of a hassle. The iMac is not so easy. Obviously, the best feature of the 2012 iMac is the screen and the skinny form factor. The only downside with my Mac mini setup is, I need a better monitor.
I recently upgraded to WordPress 3.5. One thing about WordPress updates, they are super easy. One of the best features of WordPress 3.5 is the new Media Manager. Uploading images is a breeze. Just drag and drop a file, or manually choose file and click. Viewing previous uploaded images in the Media Library is a total experience now. Thumbnails of recent uploads are displayed in rows and columns, and they are scrollable. Selecting an image and inserting it to a post is way too easy. Kudos to the development team for a fantastic job with this upgrade, and especially with the work on the new Media Manager.
