Guitar and ukulele sizes: all the numbers that matter

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

Make a ukutar

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

The Looming Face ID Debacle

As of late-October, 2017, only one week is left before the spanking new iPhone X stars shipping. I predict FaceIDgate to start within a week of the first units being received, with no end in sight. The source for this prediction is Appleā€™s own documents.

Update 11/12/17: It took researchers only five days to break Face ID, from the moment the devices were available. Read all about it here, or at the end of my post.

We’re doing passwords wrong!

You suspected it all along, and now it’s official: the “experts” have been forcing us to use passwords the wrong way. Among those practices that actually decrease security: adding weird characters to your text-based password, forcing people to change their password after a certain number of days or logins. The revelation comes from a recent document from NIST. Now there’s only hope that Government websites will start adopting the new guidelines (they’re the worst perpetrators).

In this article, I am repeating much of what I already said in this other article, but with less technical jargon and a few more months available for testing.

Page Cage released

Ever got a funny feeling when your password manager popped up offering to save a login that you thought was really, really confidential? Well, you should get it, because this is a sign that the app is able to see everything you’re doing. The developer of this app could get hacked (or the developer of any add-on or extension you’re using, for that matter), and then all your precious logins would be sent to some hacker’s computer without your noticing anything amiss. That is, until you look at your bank account and find that all your life’s savings have been sent to an account in Cayman Islands.

Page Cage is here to help you with that. It won’t work always, but it will work with a number of sites. Read More

Make an octave ukulele

An octave ukulele is a 4-string instrument tuned like a regular ukulele (gCEA, with the g being one octave higher than one would expect), but a whole octave lower. It is still played exactly like a ukulele but it sounds more like a guitar, with pretty deep bass. For those of you who actually want to accompany your singing and don’t want the instrument competing with your voice, yet are too lazy to learn a new instrument and set of chords. In this post, I tell you a simple way to make one starting from a baritone ukulele. Read More
