Checking for Solutions to Problems

February 22, 2008 by Jason

Microsoft constantly collects information about Vista from users. When a problem occurs, Vista usually asks whether you want to send information about the problem to Microsoft and, if you do, it stores these tidbits in a massive database. Engineers then tackle the “issues” (as they euphemistically call them) and hopefully come up with solutions.

One of Vista’s most promising new features is Problem Reports and Solutions, and it’s designed to make solutions available to anyone who goes looking for them. Vista keeps a list of problems your computer is having, so you can tell it to go online and see if a solution is available. If there’s a solution waiting, Vista will download it, install it, and fix your system. Read More»

Uninstalling Vista Product Keys Activates the Platform’s Kill Switch

February 21, 2008 by Jason

Windows Vista introduces a new tool on top of what its predecessor Windows XP had to offer in terms of dealing with licensing resources, from the product key to information related to the activation status of a machine. The Windows Software Licensing Management Tool can be accessed via the “slmg.vbs” command and will offer users the possibility to activate, rearm and display the activation status of Vista, but also to install and uninstall product keys. In this context, the “slmgr.vbs –upk” command, designed to uninstall a Windows Vista product key, may result on the Business and Enterprise SKUs of the operating system into the scraping of all the licensing information, synonymous with a lost activation status, and the transition of the platform into reduced functionality mode.

“After you run the slmgr.vbs –upk command on a Windows Vista-based computer, you cannot see the licensing information as expected. Additionally, the Windows Vista activation status is lost. Read More»

Convert Google Books to Sony Reader Format

February 20, 2008 by Jason

When I bought my Sony Reader, I planned to buy e-books from Sony’s on-line ebook store. But I soon realized that a lot of ebooks are available on the internet for free.

Project Gutenberg offers thousands of titles (mostly fiction) in txt format, while manybooks.net provides an impressive array of books in Sony format (as well as several other formats).

The motherload of free ebooks, however, is books.google.com. The Google folks are busy digitizing every book they can get their hands on. As of this writing, they have reportedly digitized over 10,000 public domain books, which anyone can download for free in pdf format. Read More»

Simple Zip Code Geocoding

February 06, 2007 by Jason

The ability to geocode, or translate into latitude and longitude, postal codes is a fairly useful hack to have in your programming toolbox. Quick and dirty zip geocoding allows you to do some neat things fairly efficiently and with a minimal amount of code. Though it’s U.S. centric, it allows you to add location-based functionality to your apps without requiring any real personal information to be transfered or stored.

If your application only needs to convert a zip code (or any address) into a lat/lon coordinate, say for simple mapping purposes, the easiest solution is to use the Google Maps Geocoding API. In addition to the client-side javascript functionality, you can directly query the geocoding system from php using an http request like this: Read More»

Disk Swap to pc Performance

February 01, 2007 by Jason
  • Console-based OSs like DOS have only modest memory requirements. GUI-based operating systems like Windows needs lot of memory, much larger than the RAM that is usually installed on PCs. So, they use something called virtual memory. Here, a large file on the hard disk is used in conjunction with the RAM, which greatly expands the memory available to the OS. Only the data that is required at the given moment is loaded on the RAM; the rest is cached on the swap file. Just like any other file on a disk, the swap file can also get fragmented over time and OS might seem to slow down. To prevent the swap from breaking up, you can place it on a dedicated partition (just like in Linux). Set the size of this partition at about 2.5 times the size of your installed RAM and format it. Next, you need to make sure that the OS does not reserve space on this partition for deleted files because this partition is going to have only one file – the swap file. From the Recyle Bin context menu, choose Properties » Configure drives independently. Select the partition’s tab and select the Do not move files to the Recycle Bin. Remove files immediately when deleted option. Read More»

    Understanding Images: A Guide to Resolution and Size

    January 28, 2007 by Jason

    Unless you’re a graphic designer by trade, you probably have some questions about the deceptively simple concepts of image resolution and size. Is more resolution always better? How do megapixels relate to megabytes? And can you reuse printed graphics on your nonprofit’s Web site?

    Although image resolution and size can be a very complex subject, most nonprofit organizations will probably find it sufficient to simply grasp the basic terms and concepts. To help you find your footing, we’ve answered a few of the most common questions regarding image quality and size.

    What Is Image Resolution?
    The term “resolution” refers to the amount of information a digital or printed image file contains, typically measured in pixels. Generally speaking, the higher an image’s resolution, the more detailed and crisp it will appear on a printed page or a Web site — though some extremely high-resolution images may contain more pixels than the human eye can see.
