DriverIdentifier is a desktop/webapp hybrid—install the program then launch it to scan your system for all device drivers then the program checks to see if there are new drivers available for your hardware on the web and these results are displayed in a browser tab.

Running it on my Lenovo laptop resulted in a handful of drivers that need updates such as my webcam, graphics card, and SATA controller. Clicking on the update link takes you to a page with several mirror sites from which youRead More →

If I’m ever wondering how long my PHP scripts take to execute, I add this code to the start of my pages: <?php function getTime() { $a = explode (‘ ‘,microtime()); return(double) $a[0] + $a[1]; } $Start = getTime(); ?> Then I add this to the end of my script: <?php $End = getTime(); echo “Time taken = “.number_format(($End – $Start),2).” secs”; ?> Sometimes it’s good to get hard figures on how long your script takes to execute, particularly with complex MySQL queries. If your script is particularly tardy and you want to find out where the blockage occurs, you could also try moving the $Start or $End lines to different parts of the script to measure the execution speed of each section.Read More →
