Bug: your site does not accept some valid email addresses

Summary: The character "+" is valid in email addresses!

This is the content of an email message I sent to United (the airline) about 2 years ago, since I couldn't create an account using a perfectly valid email address containing a + in it. This has been happening with other sites, so I'm posting it here so that I don't need to copy/paste it all the time. And if others want to link to it, feel free!

Edit 11/10/2011: Look at this good link resuming the issue around email regexes, with links to the RFC and some nice examples of "weird" email addresses.

Linux workshop/introduction at work

I am currently preparing what I called a Linux workshop for my techy colleagues at work. I intend it to be an introduction to the world of Linux, but by no means am I pretending to be a Linux guru, I'm just a Linux user at home (unfortunately not at work...)

I am thinking about some quick slides (max 5-10 min) to get the basic information about Linux out. I won't go too deep into the FLOSS side of things in this session, but I want them to get hands on on the system. I plan to prepare a VM that they will run on their Windows computers to get their first contact with Linux. I originally planned on installing Ubuntu 10.10 in the VMs because that's what I use at home and am most familiar with, but I recently installed Linux Mint 10, and it's pretty impressive! I might go with that for their first contact with Linux.

I will update this post with links to resources I can find on the Internet to get this presentation going. Once my presentation is finished, I'll post a link to it so that others can re-use and improve it. Stay tuned!


This year for the first time I will be attending FOSDEM, the Free and Open source Software Developers' European Meeting. I am pretty exited about that!

Looking at the list of accepted stands and lightning talks, I am particularly interested in the following lightning talks:

  • iRail: Creating a public transport API (Pieter Colpaert)
  • Village-Telco: Village Telco (Donatus Onwunumah)
  • Sahi: automated cross-broser web testing (Andreas Worm)
  • PubSubHubbub: Make your application real-time with PubSubHubbub (Julien Genestoux)
  • FreeMedForms: FreeMedForms: Managing Drug-Drug interactions: an open source model. (Eric MAEKER)
  • Forban: Forban: a simple link-local opportunistic p2p free software (Alexandre Dulaunoy)

I also look forward to meeting Fab and Dan in person, of the Linux Outlaws podcast!

See you there!

Reuse of a logo...

Walking in the streets of Pasto, Colombia, I stumbled upon this sports shop's logo:


Ever seen this logo anywhere? Let me help you:


Yes indeed, the logo of the Mono Project ;)

By the way, for the non-Spanish speakers, the name of the shop is Primate. Mono in Spanish means monkey. See the similiarity here too?

For the legal people around here, I haven't checked under what license the Mono logo was released, no idea if this is a legit reuse or not...

Some VoIP-related links

Pages I need to investigate later on to improve my VoIP setup:

I found these links after reading this Lifehacker article about using Google Voice outside of the US, which prompted me to think about my VoIP setup again (a project I'm thinking about for a long time already)

Next to that I want to find a cheap DID (Direct Inward Dialing) number in Colombia and in the Netherlands... The quest continues!
