This problem has been a mystery to me, and I figure to a bunch of other people, too: If you hit F4 in Mac OS X (or macOS) since Lion, it does not have any effect. What.
I’ve been pretty excited about the new features of EcmaScript 6 (ES6, or just “modern JavaScript”) for a while, but yesterday it really struck me how entirely different some of them make the experience of writing JS code!
I use a Mac as my main typing/character-displaying computer, and on
macOS, iTerm2 is the best terminal emulator that I’ve found so
far. In addition to iTerm2, I also use mosh,
the mobile shell, to get a fast, interactive and
disconnection-resistant SSH-like connection to hosts on which I need
to use the commandline.
The first time had a painful RSI attack was in 2003. It was as if my world collapsed: I’d dealt with hand weirdness since the late 90s (twitches, tingles) but I didn’t recognize that as symptoms of RSI. When both my hands started hurting and even everyday chores like folding laundry turned painful, I started doubting whether I could continue my career in technology.
As it turns out, it is possible to deal with RSI, not be in pain and have a career that involves a lot of typing.
At my workplace, we use github pretty extensively, and with github, we use organization teams. They allow assigning permissions on different repos to groups of people, but, are a really great way of @-mentioning people. This is wonderful, but sadly, github doesn’t make it easy for gmail filters to tell the difference between an email notification that you got because it was interesting to you, or because somebody sent a heads-up @-mention to a team you’re on.
I thought that was impossible to solve, but I was so wrong!
Let’s say you have a program that needs to do I/O on a terminal (it draws really nice ascii graphics!), but it usually runs unsupervised. If the program crashes, you want a think like s6 or systemd to restart that program. The problem here is the terminal I/O: Since most process supervision tools usually redirect standard I/O to a log file, the wonderful terminal graphics just end up being non-ascii chunder that confuses you if you try to tail the log file.
For the longest time now, I’ve admired Erlang from afar. It always seemed to be a bit daunting to take on. For one, there was the slightly weird and inconsistent Prolog-inspired syntax (I was always scratching my head over why this place needs a period and that place doesn’t), and then there was just plain weird stuff like one-based indexes.
While you don’t end up needing indexes very often, a nice syntax on top of Erlang is something I always kind of wanted, but nothing really could deliver.
I’ve just finished (mostly) documenting and writing tests for my latest little library, gmail-britta, so thought I should release it to the world as a sort of holiday gift.
Gmail-britta is a library that lets you write Gmail filters (hah, Britta, get it?) in a way that doesn’t drive you insane - you write them as a ruby program, run that program, and out comes XML that you can import into Gmail’s filter settings.
