For some educational fun, I’ve decided to build a RepRap with my younger brother.

RepRap is short for Replicating Rapid-prototyper. It is the practical self-copying 3D printer shown above – a self-replicating machine. This 3D printer builds the parts up in layers of plastic. This technology already exists, but the cheapest commercial machine would cost you about €30,000. And it isn’t even designed so that it can make itself. So what the RepRap team are doing is to develop and to give away the designs for a much cheaper machine with the novel capability of being able to self-copy (material costs are about €500). That way it’s accessible to small communities in the developing world as well as individuals in the developed world. Following the principles of the Free Software Movement we are distributing the RepRap machine at no cost to everyone under the GNU General Public Licence. So, if you have a RepRap machine, you can use it to make another and give that one to a friend…

Has anyone built a RepRap before?


Zeitgeist FS

Here’s a quick screencast of what Markus has been working on: He’s mounted a date-based FUSE filesystem using Zeitgeist and recently added html index pages for each day in the calendar.

For example, all documents that were opened on July 10th, 2009 would be in the virtual directory zeitgeist/2009/07/10.

Update: If you’re on Planet GNOME then you can watch the video here.

I’m excited about the possibilities that this opens up for rapidly getting new user interfaces off the ground. It also has tremendous potential to integrate Zeitgeist with the rest of the desktop, now. Using Zeitgeist FS, you don’t need to wait for GNOME 3 to use Zeitgeist with other applications. As of today you can just mount Zeitgeist as a virtual filesystem and browse it in Nautilus or from any app’s file chooser.


Chain Hoaxes on Facebook

A friend sent me this private message on Facebook today:

Facebook is recently becoming very overpopulated, there have been many members complaining that Facebook is becoming very slow. Records show that the reason is that there are too many non-active Facebook members and, on the other side, too many new Facebook members.

We will be sending this message around to see if members are active or not. If you are active please send to at least 15 other users using Copy+ Paste to show that you are still active. *Those who do not send this message within 2 weeks will be deleted without hesitation to create more space.*

Send this message to all your friends and to show me that you’re still active and you will not be deleted.

Founder of Facebook,
Mark Zuckerberg

I wonder how many people have fallen for this.


Hacker-Targeted Spam?

Edit: Now that I think of it, the spam most likely isn’t targeted at hackers. My email address was probably found on Ohloh and the spam bot may just be programmed to automatically include a link to the site which it found the email on.

Ugh. More spam has been getting through Gmail’s filters lately. Here’s the latest email to land in my inbox:

Hi dear,
how are you today? My name is kate, I just went Through your profile on this website (www.ohloh.net) I have no options than letting you Know that I am interested in having you as a friend, Pls write me back, I believe we can move on from here i still have more to let you know about me but that will be after i have know who you are thanks for ur understanding. I am waiting for your reply have a nice day.
From kate stay Bless.

Has anyone else had Gmail’s filters fail lately?



Quick introduction for new Planet GNOME readers: I’m a high school student in Ra’anana, Israel and have been involved in GNOME ever since GHOP 2007. After attending the GNOME UI hackfest this past October, I cofounded Zeitgeist and have been working on various new user interfaces since then. Those of you who attended the GNOME Boston Summit may also remember me from my lightning talk on problems with developer documentation.

A few weeks ago I blogged about the following mockup:

Edit: Added link to full size mockup.

Zeitgeist Mockup

I’m delighted to announce that it’s no longer just an idea! I’ve already started coding an early prototype called “Feedgeist” and the code will be on launchpad by the end of the week.

We’re planning on building sharing and collaboration features into Feedgeist. I’ll post a few more mockups on that soon.
