Essential Mac OS X keyboard shortcuts

Monday, April 6th, 2009

Learning keyboard shortcuts will significantly improve your speed, letting you focus on your work instead of boring mechanical movements. Perhaps even more importantly, though, is that they can help you avoid repetitive strain injuries (RSI).

As opposed to many other lists of keyboard shortcuts, this post focuses on the shortcuts you’ll use the most and that work for all or most apps, so they are well worth the effort in learning. The consistency of keyboard shortcuts across Mac applications is one of the nice surprises if you’re previously used to Windows or Linux :)

Loads of new Django-based FOSS components from Washington Post

Friday, February 20th, 2009

As you know, several of the core Django developers went to the Washington Post to work, and they just announced several open source components that look promising, quoting them:

  • django-projectmgr it is a source code repository manager and issue tracking application. It allows threaded discussion of bugs and features, separation of bugs, features and tasks and easy creation of source code repositories for either public or private consumption. (Looks like an alternative to Trac, but in Django.)
  • django-supertagging, an interface to the Open Calais service for semantic markup.
  • django-massmedia, a multi-media management application. It can create galleries with multiple media types within, allows mass uploads with an archive file, and has a plugin for fckeditor for embedding the objects from a rich text editor.
  • django-clickpass, an interface to the clickpass.com OpenID service that allows users to create an account with a Google, Yahoo!, Facebook, Hotmail or AIM account.

The source code is released under the permissive Apache License, version 2.0.

(Thanks to Mike for making me aware of this!)

Great interview with Greg Stein

Tuesday, April 8th, 2008

FLOSS Weekly is really on fire! The last episode of the podcast has a really interesting interview with Greg Stein, previous chairman of the Apache Software Foundation, co-founder of the Python Software Foundation, creator of mod_dav and lots of other open source projects. They touch on the disappearence of proprietary software, Google Code, how Microsoft was shipping Python as part of their e-commerce and SiteServer suites, and so on. Highly recommended.

Fun in the snow

Friday, January 25th, 2008

This video is from our ExoSocial event at Nanshan Ski Village just outside Beijing today. It shows what the few people that went to the top were up to (most people stayed on the green slopes). Fun to see programmers, PMs, and sysadms basking in the snow.

(APOLOGIES: I’ve decided against making the video public, so the video below will not work unless I share the video with you; just tell me your youtube account and I’ll share it with you.)

This was my first edit using the new iMovie. It’s a very rough cut :)

Jonathan Coulton goodies

Sunday, November 25th, 2007

I’ve been having so much fun listening to songs and watching music videos by Jonathan Coluton, an ex-software developer gone Internet music artist, or “Internet star”. He originally made headlines with his “Thing a Week” project in which he would make and publish a song every week. Merlin Mann has a good interview with Jonathan where he discusses what the process was like.

Even simpler way to ssh through a firewall

Saturday, October 27th, 2007

In his article Jacky explained how to easily drill holes through to ports on machines behind a firewall. What I normally want is to have ssh access to machines behind firewalls, allowing me to do scp, and easily ssh in without a stupid stop-over on the firewall machine.

I came across this solution that does exactly that. After the super-simple set-up I’m able to do:


  % ssh rexobox
  % rcp rexobox:some-file .
 

All that’s required is to tweak your .ssh/config. Mine looks like this on my laptop:


  Host rexobox
  Hostname exobox
  HostKeyAlias exobox
  ProxyCommand ssh fw.exoweb.net nc -w 1 %h 22

  … repeated for other hosts
 

The day the podcasts died

Tuesday, October 9th, 2007

Richard noticed that Feedburner has been blocked in China. This is terrible news as a lot of blogs and podcasts are using feedburner! No wonder half my podcasts suddenly stopped working. Let me know if you find a work-around (besides using Tor for everything).

Public wifi - how could it get so bad?

Thursday, October 4th, 2007

Warning: This is a rant.

With wifi came the promise of being online (almost) anywhere, but due to incompetent or misdirected implementation and management, it’s pretty much a patchwork of extremely unreliable networks. My experience is that there’s a 30-40% chance of actually being able to get online at an access point.
