Introducing BytePad: simple, decently secure encryption for files

Quite some time ago, I wrote an article discussing the practicability of using a file as a key for encrypting other files. As I am preparing a talk on what can you possibly do if you find your computer compromised, I thought I’d optimize the tool in that article. A couple weeks later, the result is considerably faster and more powerful than the original. At least, enough to warrant a new article. So here it is.

Learning piano not so young: The beginning

New Year 2022 resolution: to learn to play the piano. I’m sure many of you have made a similar resolution, and perhaps abandoned it after a while. I am aware of the pitfalls ahead, and so I’d like to tell you how I’ve gotten started. 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

Make a 6 String Ukulele

If you do a web search for “6 string ukulele,” you will find that a majority of links lead to the “guitalele,” an instrument the size of a tenor ukulele with 6 independent strings, which is played rather like a guitar. But a few of them will lead to the true 6-string ukulele, where two of its four strings are doubled up in octaves. This one is played like a regular 4-string ukulele, but sounds richer, more uke-like if that were possible (see this video, for instance). True 6-string ukuleles are hard to find, and those that you do find tend to be pricey, but in this article I show you how to convert a regular ukulele into a 6-string uke with a minimum of hassle and expense.

Two very different pickups, one instrument

My latest ukulele is an exercise in versatility: short enough to go inside a suitcase, long enough to be remain playable under heavy capo and, of course, both acoustic and electric. And not just merely electric, but featuring both a passive piezo pickup and a magnetic pickup, which can be mixed in any ratio. I looked for a wiring diagram that could do this, and found nothing simple. They all required a switch to select the main pickup, with perhaps the ability to add a bit of the other, or had something weird about them. Since the two pickups are very different electrically, there was no assurance that they would mix well. I took a guess, and it worked, though theory predicted that it shouldn’t have. Read on for the solution.
