When buying a display, it is best to use a dedicated application to make a full quality test (such as whether it has dead pixels), so as to avoid identifying problems during later use. At this point, IsMyLcdOK can be a good and effective solution. Its file size is only less than 50 KB, runs directly without installation, also does not need other runtime environment. In other words, you can use a USB flash drive to take it with you when choosing and testing a display.

A few days before I wrote this post, my laptop keyboard had at least 9 keys broken due to water splashing. In the meantime, I first used the Keyboard Map Tool to temporarily modify the key mapping of those broken keys in order to continue to use this keyboard constrainedly. Afterwards, I found this Keyboard Test Utility, which helped me determine all the broken keys. In the end, I also use it to test the validity of all keys on my newly-bought USB external keyboard.

In 2009, AppNee discovered and collected CyberLink's YouCam this excellent camera effects embedding software in the CD attached with a Lenovo computer for the first time, and once wanted to share it in no time. But due to its too big file size (for a camera auxiliary application), I've been putting its release date at AppNee off, until today.

Solid-state drives (SSD) have obvious advantages than the traditional mechanical hard disk drives (HDD), but do not mistakenly believe that an SSD does not need optimization. However, for the optimization of SSD, many users may just know one optimization setting - a new SSD should be formatted with 4K alignment. In fact, SSD actually has a lot of places that can be optimized for making its speed faster and service life longer.

DriverPack Solution (formerly called DriverPacks) is a revolutionary free hardware drivers detecting and updating online/offline solution from Russia that applies to all hardware. Scrupulous users may see that its official website is still using the top-level domain .su (Soviet Union) in the Soviet Union era (ICANN has made many efforts to eliminate it, but always ends in failure).
