What’s the fastest way to master console stuff like
emacs? Force yourself to use it exclusively, of course. But maybe you’d be tempted to cheat with a desktop. We know we would be. In that case, you ought to build a console-only cyberdeck like this sweet little thing by [a8skh4].
This cyberdeck serves another purpose as well — the keyboard layout is Miryoku, so [a8ksh4] can get more practice with that at the same time. Fortunately, the layout is built for
Inside is a Raspberry Pi 4 and what looks to be an Arduino handling the keyboard input. The Paper Pi spotlights a 4.2″ e-ink screen between a split thumb keyboard that’s made of soft, silent, tactile switches.
Since they’re SMD, [a8ksh4] made clever use of header pins to get them to work with protoboard. As much as we love the keyboard, it would be awesome to see a few switches on the shoulders or even the back that make use of the rest of the fingers. Check out more build pictures in the gallery.
We love to see cyberdecks with split keyboards, because you shouldn’t have to sacrifice ergonomics in a portable computer. Here’s one that comes in three pieces, making it easy to get the spacing between the halves just right.
If you grew up with Unix systems like we did, you’ll be sorry to hear the news: vi, the noble text editor that has served us so well these 40 years, is going away — from many GNU/Linux systems, anyway. As of this writing, GNU/Linux Mint, Debian, Ubuntu, and OpenSUSE — four of the five most popular GNU/Linux distributions — have all announced that they will no longer ship the ‘vi’ editor as part of their base installs. For those of us who got our start in the punched-card era and still think of files as a collection of lines instead of a stream of bytes, this is a major blow. But, we can all take some comfort in the fact that, at least for now, the stripped-down version of vim synonymous with vi on these systems will continue to be available from package repositories.
The reasons for the move aren’t entirely clear to us, but from what we can see on the GNU/Linux mailing lists, the confusing modal interface and the fact that novice (and many seasoned) users can’t figure out how to save a file and exit the program seem to have influenced the decision. Also cited were support changes expected as GNU/Linux gains in popularity. As the user base expands to include less technically-savvy individuals, fewer people will be able to fix their constant boot issues, which is the primary use-case for vi. Replacing the self-help model will be a support infrastructure where users can take their machines to “GNU/Linux Geniuses” who will solve the problems for them.

When it comes to managing ingredients and baking at a professional bakery, we know that most people would turn to an SQL database and emacs. Really, what else do you need? Okay, so maybe there are a few who would think that emacs couldn’t help you with this, so, here’s how [Piers] uses emacs and PostgresSQL to manage the day to day needs at his bakery.
[Piers] had tried a spreadsheet to keep track of things, but didn’t really like it when he had to create a new recipe: “lots of tedious copying, pasting and repetition of formulae” is how he put it. As a ex-professional programmer, [Piers] was familiar with emacs and so set up a daily worksheet in emacs using org-mode. Each morning he runs org-capture to create the template for the day’s work. Some code in the org file (run with org-babel) can run a query on the database. He’s created some code to set up each day’s journal entry and to run the complicated database queries that he needs.
There is a list of things that [Piers] is working on next, including ingredient order management and accounting, but it works for him. And to stop any potential flame wars that might break out, it’s good to mention that the system does just that: It works for him. There are other possibilities. Take a look at Al’s Editor Wars article, or Elliot’s rebuttal, or, ignore the wars and read this article on baking with steam.
In the secret Hackaday bunker, we have some emacs users, some vi users, and some people who don’t really care. However, even the staunchest of our emacs supporters had to do a double take at [Vreeze’s] project that creates a GameBoy emulator using the venerable text editor. You can see [Alexei Nunez’s] reaction to the emulator in the video below.
The Eboy uses unicode characters to output the graphics. You can use emacs commands to load ROM images and use your keyboard to control the game.

Linux users–including the ones at the Hackaday underground bunker–tend to fall into two groups: those that use vi and those that use emacs. We aren’t going to open that debate up again, but we couldn’t help but notice a new item on GitHub that potentially negates one of the biggest complaints non-vi users have, at least for vim which is the most common variant of vi in use on most modern systems. The vim keybinding makes vim behave like a “normal” editor (and to forestall flames, that’s a quote from the project page).
Normally vi starts out in a command mode that it calls normal mode. Pressing a key will execute an editing command, unlike most other modern editors which just insert characters into the open file. For example, pressing x will delete a character. This surprises most people who aren’t familiar with vi. In all fairness, there are other older editors that work this way, but they usually were not screen-oriented.

As a rule, I try hard not to get sucked into religious wars. You know, Coke vs Pepsi. C++ vs Java. Chrome vs Firefox. There are two I can’t help but jump into: PC vs Mac (although, now that Mac has turned into Unix, that’s almost more habit than anything else) and–the big one–Emacs vs vi.
If you use Linux, Unix, or anything similar, you are probably at least aware of the violence surrounding this argument. Windows users aren’t immune, although fewer of them know the details. If you aren’t familiar with these two programs, they are–in a way–text editors. However, that’s like calling a shopping mall “a store.” Technically, that’s correct, but the connotation is all wrong.
Like most religious wars, this one is partly based on history that might not be as relevant as it used to be. Full disclosure: I’m firmly in the Emacs camp. Many of my friends are fans of vi–I try not to hold it against them. I’ll try to be balanced and fair in my discussion, unless I’m talking about my preference. I don’t have to be fair when it comes to my opinions. Just to be clear: I know how to use vi. My preference isn’t based out of not wanting to learn something new.

compact keyboards that do away with a third of the keys you would usually find on a normal-sized keyboard are all the rage now, but for [jonhiggs], they weren’t good enough. There is a long tradition of Unix shortcuts these compact keyboards don’t pay attention to – CTRL-A being the Home key, and CTRL-D being the Page Down key. To fix this horrible oversight of Unix history, [jon] tore apart one of these compact keyboards, rewired the switch matrix, and made his own perfect keyboard.
The keyboard [jon] is using is a Filco Minila, a very nice and high quality keyboard in its own right. After mapping out the switch matrix, [jon] wired all the switches up to a Teensy 2.0 loaded up with the TMK firmware. This is a pretty standard way of building a custom keyboard, and [jon] could have just cut a switch plate and installed panel-mount switches and wired up the matrix and diodes point to point. The case for the keyboard is constructed out of Lego.
Because this is a true, modern Unix keyboard, [jon] needed to connect this keyboard to a box running his *nix of choice. He’s doing this in the most future-retro way possible, with an Amazon EC2 instance. This project isn’t done yet, and [jon] is hoping to add an ARM dev board, an iPad Retina display, battery, and SSD, turning this into a completely homebrew laptop designed around [jon]’s needs.
