This Excel VBA function allows you to take a column of values (e.g. ID numbers) in one worksheet, and use that to get corresponding values that are in a second worksheet.

Logitech K750 Review – Best Wireless Keyboard Review

L

I was using the Logitech K340 keyboard for around a year. Back then, the Logitech Wireless Solar Keyboard K750 was not released yet. While the K340 keyboard was great at the start, after some time the keys would get stuck. E.g.

One of the first problems that I came across the Mac was the “File in use” error that occurred whenever I tried to unmount a hard drive, or unmount a USB thumb drive. It was annoying because I didn’t know how to find the source. In Windows, I would face the same problem too, but I had a program that I used to tell me the offending application.

How To Use jQuery with MooTools

H

I was using them while I realised that I had to use both of them on a single page at one point.
