Extract data from other Excel worksheets using VLOOKUP

My landlords approached me and asked if I knew anything about Excel. My initial thoughts were “I know how to add and subtract with =SUM() and that’s about it”. But I thought, how hard can it be? They tasked me to sort their product list into one file so all their products had the appropriate product codes, UPC codes, descriptions, cost & sell price and physical attributes (length/width/height/weight). The idea was to then import the …

ASUS UX32A not detecting SSD

Is your ASUS UX32A or UX32VD not detecting the iSSD? You’re not alone. Read on… Yesterday the iSSD on my Zenbook died. It wouldn’t be recognised by the BIOS, within Ubuntu, live boot of gparted or even get in to Windows. The POST would just hang for a good 10-15 minutes before it reached GRUB, and even then it wouldn’t go into Windows as the UX32A makes use of ExpressCache and Intel Rapid Storage Technology with …

A comparison of rsync vs. rdiff-backup

Abstract rsync and rdiff-backup are both incremental solutions, so only the differences in files from source to destination are transferred, not the entire source. rdiff-backup is more CPU intensive than rsync because it SHA-1 checksums everything it encounters[1][2], so if a hash of a file in the destination directory is different to the source file, it then calculates what the differences are between the two and pings them over. rsync, however, is super quick. It doesn’t checksum …

Cycling without a helmet

Yesterday I was knocked off my bike, as a driver turned into a junction without noticing me beside her. Fortunately, no injuries were incurred other than a few cuts and bruises.
