![]() Who knows what catastrophes were averted thanks to me!Įxcept of course this was hardly scientific and the results should be taken with a grain of salt. It has been scientifically proven that Programmer Dvorak is better than regular Dvorak. Histogram of characters used in text files authored by me present in my Git repositories excluding Emacs Lisp files. Since letters are on the same position on both layouts in question, only digits and punctuation characters are compared on the histogram: Not number row Unshifted (number row) Shifted (number row) - ". To test this I’ve grabbed all my git repositories and constructed a histogram of characters used in text files present there. The hypothesis goes that developers use digits less often thus such design optimises the layout for them. The main differences between the two is that in the former digits are entered with Shift key pressed down which allows several punctuation marks often used when programming to be typed without the need to reach for Shift. I’m talking of course about the decision to learn Programmer Dvorak rather than a regular Dvorak keyboard layout. But did I make a wise choice? Or had I chosen poorly? Had I went a different path, the pl(dvp) layout might have never seen the light of day. Please send your comments and suggestions to denisk1985gmailcom, I'll really appreciate it!Īlso, if you have an idea of how to improve the lessons, don't hesitate to submit a pull request.Update: The article was updated in October 2021 to include direct comparison shift usage between Dvorak and Programmer Dvorak layouts.Ī few years age I’ve made a decision that had the potential to change the course of history. If you use (K)Ubuntu then the layout is already installed, you just need to select it you can also find the instructions of how to configure the layout on Windows,īase Dvorak course then a regular Dvorak layout, which is shipped with most of operating systems, should be enough. You'll need to have Programmer Dvorak layout activated in order to use the lessons for number row. Which allows to create arbitrary typing tutor user interfaces. Programmer Dvorak typing tutorial utilizes a jQuery plugin Its source code can be found on GitHub under Lessons 30 - 52 cover Programmer Dvorak layout aspects (lessons for typing digits and special characters such as &[(%# etc. For base Dvorak course this tutorial uses magnificent ABCD lessons written by Dan Wood. This typing tutorial covers base Dvorak layout and, in addition to that, parts of the layout that are Programmer Dvorak - specific ![]() Published a book, Typewriting Behavior, which is in-depthĪ very nice and funny description of the history of QWERTY and Dvorak layouts is given in a comic book, Dvorak Zine The keys have been placed in random, inefficient way for one sole purpose - to slow down a typist.ĭr. ![]() Original QWERTY layout was initially designed to prevent the keys of old typewriters from jamming.
