LibreOffice Calc – VLookup with dates
In a different post on this blog, I showed how to use Vlookup to match lists. Someone commented on that post and indicated that it didn’t work with dates. It turns out, it does, but… There is a slight tweak required to make it work. So, if you want to learn how to use VLookup,…

Linux FFMPEG – Flip Vertical Video to Horizontal
I was recently shooting some videos on my phone to share with someone else and accidentally flipped the phone before filming a clip.

Linux – Batch Convert .wav to .flac

I have a VPS server with Linode that I use to host about a dozen different websites. All but one of them run on WordPress. Occasionally, I get a request to add another domain and website to the server. It’s not terribly time consuming to do, but it does require a number of specific steps…

For a recent project, I came into possession of hundreds of photos, each of which was named according to the settings the person who take the photo with their phone had in place but ended with ” – FirstName LastName.jpg.” I wanted to keep the users’ names, but everything before that could go. With hundreds…
