All my crypto apps updated

It’s a fairly small change, but one that may mean much. The versions I just pushed out include an icon on the toolbar, plus sometimes a special button, in order to download encrypted and decrypted files loaded in the box as a link. This gets around the file size restriction of the right-click and “save as…” method that was used until now, especially on Chrome. I’ve been able to load and save files over 1 GB in size.

In this article I review the different learning methods I’ve surveyed, the instrument I chose, my general setup, and some basic ideas about the whole thing. I cannot promise this will work, so stand by for another article a few months from now telling you how it went.

6-string ukulele tunings

Six-string ukuleles are getting quite hard to find, and it’s a shame because they sound particularly ukulele-like, at least to my ears. In this recent article, I tell you how to convert a regular 4-string ukulele into a six-stringer with conventional tuning, but I found that there are a lot more tunings you could use, and some sound just as sweet as the standard. In this article, I go through the math and give you some samples. Read More
