Problem

If you have an old version of Hallmark Card Studio and recently upgraded to Windows 10, you might be running into the following error when launching the program. The specific program I ran into this with was Hallmark Home Card Studio version 22/hcs.

With Red Hat OpenShift, here's how to view logs of a pod in a different project than the one currently active:

oc logs -n <project> <pod>

Option as documented but obscure and hard to follow because the option is namespace but oc always references them as projects everywhere else:

Problem

We were dealing with an out of order dump of photos from a Google photos album and wanting to upload to Facebook. It consisted of jpg and heic photos from a iPhone 8 and Pixel 4a so the metadata was different.

Sorting by Date Created in the macOS finder was out of order and Facebook seemed to sort in the same way. It didn't make any sense because we were seeing 4:55am photos sorted below 4:56pm photos (same day). Regardless of Italian timezone, they shouldn't be sorting like that (it's only GMT+2 vs my local GMT-6) which is an 8 hour difference compared the 12 hour difference shown in the photo date/times. Even looking at the exif metadata, it didn't make any sense what it was pulling from to make it sort that way.

Solution

This uses exiftool to read and do the file manipulation.

How to escape a forward slash in a test name when using -run to run a single Go test?

I don't think it's possible. The following are some other articles/blog posts reiterating this point.

The key seems to just not use any forward slashes in test names so you can target them individually no matter what.
