July 19th, 2010Invisible captcha
June 22nd, 2010In the last commit, we have added an invisible captcha in order to avoid Spam bots to create automatic accounts in our installation. The idea is to use an invisible field in the Join us page of Jarifa.
Spam bots usually fill any field they find, and more importantly, as they don’t usually analyze CSS, they will fill the honey pot field to know when a user or a bot is filling in the form.
Additionally, the name of the field form changes dynamically each week, so it will be more difficult for Spam bots to obtain a knowledge about how it works the captcha.
Give it a try, upgrade your installation and let us know if you have found an improvement thanks to this new feature.
Geolocation for Jarifa
June 14th, 2010
Jarifa has added support for geolocation enabled browsers like Mozilla Firefox 3.6. If you want to try it, just click on your Jarifa link to create a new volunteer user, and a menu will ask you if you want to share your location. Thanks to this new feature, the form fields of country, city and state will automatically field up.
Fixed a security bug
June 9th, 2010
In the last commit of Jarifa, we have fixed a security bug that allowed any person on Internet to change the projects based on the votes by visiting only one URL. Right now, in order to change the projects a password is required, so it is not possible to change them unless you know the password.
If you were using these feature, please upgrade right now fetching the source code from the git repository.
Microblogging support in Identi.ca and Twitter!!!
April 13th, 2010
Jarifa now supports Identi.ca and Twitter microblogging sites in its last GIT commit. Thanks to this new feature, the volunteers of Jarifa can become followers of the project, and more importantly the project will be spread automatically in social networks like Identi.ca and Twitter.
Jarifa by default, only supports Identi.ca, the open-source microblogging alternative to Twitter. Nevertheless, thanks to a feature of Identi.ca, it is possible to post to Twitter via Identi.ca by linking the accounts. In this way, Extremadurathome is now publishing in Spanish its updates to Identi.ca and Twitter.
