SQL Server Express 2008
About:
Microsoft SQL Server Express, a freely-downloadable and -distributable version of Microsoft's SQL Server relational database management system, comprises a database specifically targeted for embedded and smaller-scale applications. Unlike its predecessor, MSDE, it lacks a concurrent workload-governor to "limit performance if the database engine receives more work than is typical of a small number of users."[1] It does, however, have a number of technical restrictions which make it undesirable for large-scale deployments, including:
- maximum database size of 4 GB per database (compared to 2 GB in the former MSDE). The 4 GB limit applies per database (log files excluded); but in some scenarios users can access more data through the use of multiple interconnected databases.
- hardware-utilization limits:
- Single physical CPU, multiple cores[2]
- 1 GB of RAM (runs on any size RAM system, but uses only 1 GB)
- absence of the SQL Server Agent service

Green computing, the study and practice of efficient and eco-friendly computing resources, is now under the attention of not only environmental organizations, but also businesses from other industries. In recent years, companies in the computer industry have come to realize that going green is in their best interest, both in terms of public relations and reduced costs. This article will take a look at several green initiatives currently under way in the computer industry, as well as issues that have been raised regarding these initiatives. We will also have a talk with VIA to learn more about the future of green computing. |

This time last year, we tested 61 2006 HDTVs to learn how they process all the detail contained within 1080i, the most common high-definition broadcast format. It's the highest resolution format the majority of HD broadcasters and cable channels use, including CBS, NBC, CW, HBO, and Showtime. The results of our 2006 tests were quite disappointing; less than half of the HDTVs were able to properly process the interlaced broadcast signal to the TV's native, progressive resolution. This year, we have expanded our testing to include 74 HDTVs that range from 19 to 67 inches. We have added a new test for 1080p displays to judge their resolution with motion as compared to their stationary resolution. This test illustrates how all HDTVs lower the amount of detail you can see when the camera is panning or where there is action in a scene, such as on a football field. More on this later.  |

The standby and hibernate modes in Microsoft's Windows XP and the sleep mode in Vista are meant to be great time-savers. But too often a sleeping PC wakes up on its own--or doesn't awaken when you want it to. |
