You can find the Sample program on GitHub.

• Clients do now cryptographic authentication the main server and each other.
• Major rewrite of threading/asynchronoucity infrastructure inside the core

You can download for Windows and Ubuntu Linux on http://sflx.net/beta, there you can also create the necessary login.

The source code is available on GitHub.

• Lock Screen: Panel: Add New Item / Action Buttons. Then in Action Buttons Properties you can set the first button action type to “Lock Screen”.
• Switch User: gdmflexiserver (in Terminal or via shortcut)

Tested on Fedora 15.

Schneeflocke is designed to be a Friend-2-Friend file sharing system. It’s like a IM client for sharing folders (and without the chatting functionality…). In order to use it, you just have  to

• signup on sflx.net/register – this is to prevent spammers
• Download the  client on sflx.net/beta/downloads
• Login (don’t forget to set your login credentials on view/settings dialog)
• Add your friends with Add/Contact…
• Share a directory with File/Share…
• Enjoy sharing…

The source code can be found on GitHub.

Don’t trust my server? Just use your own XMPP Server (e.g. Prosody).

Note: Although the connection is encrypted, its not yet authenticated – an active attacker can still compromise security and sniff your traffic.  Not all NATs can be traversed in the moment, only basic UDP hole punching is implemented. This is a BETA version.

And now? Now that Schneeflocke is released for the first time, I will try to get into the reachability problem, either by increasing the NAT hole punching algorithm or by implementing some kind of a tunnel algorithm.

The bad: In ubuntu (11.10 Beta) it’s always noisy due to a bug in their kernel.

Power consumption in idle: 42W, measured with PowerTOP. Thats enough, to keep the fan running all the time.

In contrast, Fedora 15: 24W. While playing HD Youtube videos: 37W. That’s less enough to keep the fan off. And nearly 40% off.

BTW: Ubuntu 11.10 doesn’t include Gnome, just their Unity. In my opinion even Gnome3 is more useable than Unity. But why on earth does each new WM copy the bad tab-switch-behaviour from OSX?

Update
Arg, the Kernel update to 2.6.40 (3.0 ) brought the problem back, so again 30W of consumption. After disabling nouveau (which isn’t that easy (german)) and unloading the NV 540M core via acpi_call it’s again at 19W. Disabling the nouveau driver also brings the suspend mode to work (with nouveau it’s just a matter of luck).

See the report here at long its online!

• C++ Parser can now parse Function Declarations (still no real template support)
• With this information, a new code generator named RpcGenerator can create helper functions for RPC-Calls. The RPC format is a proprietary JSON based format I also used in my diploma thesis (Basic format: [Command-Name, Arguments in JSON, Binary-Data]).  It shall be possible to create other Rpc-Generators or wrappers as well, using the parsed function declarations
• The enum fromString() generator now uses a slightly packed statically generated hash table, which is smaller now. I moved the generating code to StaticHashTableBuilder (link) so that other Generators can also use these tables.
• Some minor bugfixes

0.2 can be found here

update: already on 0.2.1 (bugfix only)
