If your WiNE or Playonlinux installation of Hearthstone or Blizzard's Battle.Net client has suddenly stopped working after an update, one thing to try is to check if a newer version of Wine is available and install that. This usually gets me out of trouble with my Playonlinux installation.
So, Blizzard is offering a gift to players for some reason (possibly for a bug, I forget). But on my Linux install (via Playonlinux), clicking the Gifts button at the top just brings up a blank screen. You are supposedly also able to claim the gift by logging onto battle.net in a browser. But where does one go from there? There's a "Gift history" option in your account settings section, but that does not list anything that is claimable.
So I've been having trouble getting a Windows program to work in Wine (Windows emulator) on my Kubuntu 16.04 system. It's a simple program but one that requires .NET 3.5. Considering its simplicity, I thought that it'd work fine using just Mono and it did fire up. However, it wasn't terribly usable throwing constant errors and being very buggy. So I had to also install .NET 3.5.
So here I was happy with my installation of program foo.exe under Wine in Linux (Kubuntu if you must know). All of a sudden, the program starts whining a little, wobbling a touch, and generally exhibiting wonky tendencies. While I could have uninstalled it and tried to reinstall it to see if that fixes the problem, there's a neater solution that is only available for Wine users.
The latest version of Picasa (v3.9) is armed with Google Plus support. I suppose that this is fine even though Google Plus is inherently evil (albeit not as evil as Facebook). However, the application's camera support is lacking and Google has officially stopped supporting the product under Linux. They've also pulled many of the links and even download sites and archive sites are oddly only providing v3.9. However, Google's own servers continue to (knowingly or unknowingly) host to install file for the admirable robust v3.8. Here it is:
