Collaboration-tool-shootout.
Kugg and Olle3 were doing collaboration now there are some different technologies in GNU /Linux systems to share one screen on two remote computers Olle and Kugg tried some of them.

The not so neat thing with “screen” collaboration is that there is only one cursor. However local editing and pasting makes that endurable.

Mini howto (hosting party):

screen -S loldongs
C-a :multiuser on
C-a :acladd root

Howto screen (client):

sudo screen -r loldongs/

We discussed the possibility of using a “Posix pipe” (fifo) for shared editing. It worked one way.
Fifo filesharing howto (host)

mkfifo /tmp/loldongs
chmod o+r /tmp/loldongs
cat >> /tmp/loldongs
"lorem ipsum type type type
C-d

Fifo filesharing (client read only):

tail -f /tmp/loldongs

We also gave gobby a go but it turns out gobby no longer has a client in OS X.
Do you have a better idea on how to share a screen safely in a multiuser GNU-Posix environment? Please do comment below!


Flash to Android
jonasb and StG did more grunt-work on their Flash-to-Android solution. “It is a lot of work, but I want to concentrate on it, and finish it.”, jonasb said.

Faidros brings the stuff
phaidros brought a bag of ad-related hardware trinkets. The “vultures of trash” descended on the loot like iron filings to a magnet. “Let us build a SOMETHING-SOMETHING!” they exclaimed exuberantly. We shall see. Looks like this will turn out to a 3d speaker array.

Pinball refurbish
StG showed photos and told stories about his refurbishing a 1972 pinball table. “There was a list of Common Fixes circulating, things you should fix anyway, because they always break. I ignored it, and got me a schematics of the whole machine. Begun following the leads. Built and cleaned and repaired. Learnt a lot of things. Ordered stuff from all over the world. Spent like 200 EUR getting the machine, and some more in parts. My work was long, like three or four months. In the end the thing ran! Cross-checking the list that the old farts on the Net had published, it turned out I had only fixed Common Fixes.”

Inkscape tutorialism
olleolleolle learnt some more about Inkscape, and worked on hand-tracing vector images from photos. http://inkscape.org/ is Free software. Here is an image created that evening.

Variable Power supply
phrst built a variable power supply for a used device he’d bought as a present. He used a sound box to house it, which looked very professional. To be used with a tatooing machine.

Xbox 360 fixing and re-heating

UNKNOWN(coolguy) did a miracle to the broken XBox 360, and made it one step less broken. A large blanket and some bravery was used it “free-soldering” the console’s boards in place. “I just watched some YouTube videos, read some forums. It’s not very difficult.” He certainly had the required bravado. The xbox360 had some broken soldering joints. Apparently on some known sensitive joints. The soldering joints had to be covered with additional metallics to make sure the specific sensitive components would heat up in the next stage. The entire Xbox was then tied up with a blanket and then turned on, this would heat up the entire device so much that the soldering joints would re-heat and connect again.

Funny thing was that this way of fixing devices is not exactly going by the book. It was certainly dismissed by electronical experts when the idea was introduced but is now defacto standard way of fixing broken Xbox360′s.

And you know what? It worked!

As usual, there were some found food (pasta pesto), found candy, and general socializing.

If you are into software or hardware experimenting, repairing, building, join us next Tuesday.
