Importing all of your orgmode notes into Apple Notes for mobile access.

Over the years, I’ve built up quite a collection of notes as Org mode text files. So far, it has proven to be the most expressive and the most robust note-taking modality out of a long list of candidates that I’ve tried. Note-taking using Org mode has one big drawback however: Mobile accessibility. In other words, consulting one’s org mode notes database from a mobile device is painful. This should not be the case; notes should be always and instantly available, even on mobile.

Configuring Emacs, lsp-mode and the python language server.

The language server protocol was proposed by Microsoft as a way for different editors and development environments to share language analysis backends This post describes how to configure Emacs, lsp-mode and the palantir python-language-server for improved code intelligence when working on Python projects. (I’m planning a companion post for Emacs, C++ and the cquery language server.) Goal Before starting, it is motivating to see what we are working towards.

Interactive programming with Fennel Lua Lisp, Emacs and Lisp Game Jam winner EXO_encounter 667

Phil Hagelberg recently won the Lisp Game Jam 2018 with his entry EXO_encounter 667. What I found most interesting however, was his interactive programming setup. He programmed his game in (and contributed new features to) a Lisp to Lua compiler called Fennel, and used the game programming library Löve. With Emacs and some Lua thread magic, *he was able to perform runtime changes and introspection to his live running game project*.

Asynchronous rsync with Emacs, dired and tramp.

tmtxt-dired-async by Trần Xuân Trường is an unfortunately lesser known Emacs package which extends dired, the Emacs file manager, to be able to run rsync and other commands (zip, unzip, downloading) asynchronously. This means you can copy gigabytes of directories around whilst still happily continuing with all of your other tasks in the Emacs operating system. It has a feature where you can add any number of files from different locations into a wait list with C-c C-a, and then asynchronously rsync the whole wait list into a final destination directory with C-c C-v.

Developing Arduino sketches with JetBrains CLion: A minimal example.

The official Arduino Desktop IDE is fantastic at what it was made for. After downloading, opening your first sketch (say, blink.ino) and flashing this to your connected Arduino hardware takes all of 3 seconds. However, once your sketches become a little more complex, a more sophisticated IDE with code navigation, documentation and context-sensitive completion can be a great help. Currently, one of the better solutions is the Arduino extension for Visual Studio Code.

Which jumper to set on the ITEAD XBee shield v1.1 for use with a 3.3V Arduino

I had to use the ITEAD Studio XBee shield v1.1 with an Arduino m0 (SAMD21) board, which is a 3.3V board, whereas the most common Arduinos are 5V. At the time of this writing, the shield’s website was not very clear on how exactly to set the jumpers (zone 5: “When operated in 3.3V, install the jumper” — which one?!), and the rest of the internet also did not seem to know.

Use the Google Cloud Speech API to transcribe a podcast

As I was listening to the December 21 episode of the CPPCast, together with TWiML&AI my two most favourite podcasts, I couldn’t help but be a little bewildered by the number of times the guest used the word “like” during their interview. Most of these were examples of speech disfluency, or filler words, but I have to admit that they detracted somewhat from an otherwise interesting discourse. During another CPPCast episode which I recently listened to, the hosts coincidentally discussed the idea of making available transcriptions of the casts.
