Hardware is hard

Where I live there aren’t really any options for electronics shopping, so I was resigned to do it mostly through mail order. Fortunately I discovered that Kjell & Co., which is probably the closest thing to Radio Shack we have in Sweden, not only carries a lot of Arduino stuff, but also has an shop in the next town over (Luleå, about 50km away).

The Joy of Hardware

Last year Jfokus ran an embedded systems track alongside the main conference, and this was met with considerable enthusiasm. It was a friendly refuge from corporate keynotes and enterprise bloatware seminars, a place where you could escape the buzzwords and marketing people. I discovered that the Raspberry Pi was an actual thing that existed and could be ordered from the internet, and within 60 minutes I had done just that.

Emacs Protip: org-mode

Man, where do I start? org-mode is Emacs’ Killer Application. It started out as an very capable outlining tool, but has grown and mutated and now people use it for time management, blogging, presentations, spreadsheets, GTD, you name it.

Inbox

It’s funny how things change. I used to hang out on a lot of mailing lists back in the day, some pretty high-volume ones. Two that come to mind were the Belle and Sebastian fan list and an extremely casual chat list for bored young IT professionals. I had my email client of choice (mutt) fired up and checked it obsessively throughout the day.

Emacs Protip: sexp commands

After having internalized the other-window commands, I’m now focusing on commands working with balanced expressions (or s-expressions). Depending on the current buffer mode, this can be a word, a string literal, an XML tag or a LISP expression. The ones I’ve found most useful are:
