This May 14th, a group of German security researchers revealed EFail, a successful attack against PGP (short for Pretty Good Privacy), and S/MIME, the leading methods for end-to-end encrypted email nowadays. You can read their shorter post here, and their full paper here. I’ve contacted a number of people who wrote about it to tell them about PassLok and its immunity to the EFail attack. This post adds more details to what you may shortly found printed elsewhere. Read More
For quite a while, I’ve been interested in making a guitar or ukulele sound like other instruments. The way a guitar sounds when strummed appeals to me, since it blends so well with singing to make a song, but I get bored quickly with things always sounding the same. This is while I’ve built a number of ukuleles in the last few months and my collection now counts some 15 units. There is this device called “MIDI guitar controller” that you play like a guitar but can sound like anything else, since what it does is get real-time note information from your performance, which can then be fed to a hardware or software instrument. Most MIDI guitars, however, are either discontinued or very expensive. I was resigned to never using one until I ran into the “Rock Band 3 Fender Mustang guitar controller pro” (whew!), which is now selling (new) for a tad over $50. This article expounds how this relatively cheap device compares with much more expensive devices. Read More
There are a number of MIDI-enabled guitars out there, but did you know now there is also a MIDI ukulele? Kudos to Maker Hart for their courage in developing the DU-one and EU-one instruments. They were kind enough to send me a free DU-one so I could write this review. Short version of this rather long article: it takes a lot of effort and frustration to get it to work, but in the end it is all worth it. Read More
Or you can call it a cigatar, if you like, because we’re starting from a cigar box guitar, pictured at left. The point of this article is how to change its tuning so it can be played exactly like a ukulele, without having to buy new strings. This also works for a G6 baritone to C6 standard tuning conversion, if you have a baritone ukulele. Read More
All my crypto apps, with the exception of those meant to be performed also by hand, have been upgraded to include the powerful DOM Purify filter, which removes malicious content from web pages. This is in case you get an encrypted message with a malicious payload, which might execute and do something nasty as soon as you decrypt it. Apps involved: PassLok, PassLok for Email, SeeOnce, URSA.
One year after I started learning the ukulele, I have learned to accompany many songs by strumming. But I still divide them into “easy” (key of C), and “all others” (any other key). This is because the basic chords involved in a song written in the key of C (C, F, G7, Am, Dm) are especially easy on the standard-tuned (gCEA) ukulele. But it turns out that the “easy” songs are only about half the songs in most books. One solution is to use a capo, but then the sound goes from tinny to tinnier, especially if the difference is large (say, a song in the key of G, which would mean a capo on the 7th fret; try that on a soprano!).
But I’ve found a better solution, and this is to get a second uke and turn it into a “cuatrolele” by simply swapping the order of the strings. As a demo, I have sound samples for a soprano uke originally tuned in C6 (gCEA), which has become a G6 (DGBe) g-ukulele, or “gukulele” for short. Read More
As part of the ukutar project, I looked for small guitars that I could turn into ukuleles, and found there is a bewildering array of names that often don’t describe very well the size of the instrument or how it sounds. Pictures are pretty much useless. In this article I present a table with most of the guitar and ukulele sizes I’ve found, and try to make some sense of the numbers. Read More
PassLok did it first, and now SeeOnce and URSA have followed. Both are available as extension/addon at the Chrome and Firefox web stores. They are just one click away, and are protected from interference by other code running on the browser. These are the links for SeeOnce: Chrome, Firefox, and for URSA: Chrome, Firefox. And, for good measure, PassLok: Chrome, Firefox, and PassLok for Email: Chrome, Firefox. Read More
Here we go again with a “new” hybrid instrument. A ukutar is a guitar that wants to be a ukulele. It has four strings and it plays exactly like a ukulele, but it sounds rather like a guitar, with all that deep resonance that we love in the instrument. Read on to see how you can make one with a $30 budget. There’s also some sound samples. Read More
