Here are some notes from the meeting yesterday in no particular order. They 
are not exactly a report, but may be better than nothing.

#. About 20-30 people came in my approximation, some of them a little late, so 
it was pretty successful. So hopefully it was a good decision to find a venue 
which can afford starting at a later hour. We'll see if the trend of 
successful presentations can continue.

I think I recognised most of the attendees, but there were some new faces, 
which is good.

#. Sawyer gave a very good presentation in my opinion, and I've learnt some 
new stuff about git there. There was some good involvement from the audience. 
Next time, I'll try to pass the baton to a different lecturer, because I think 
Sawyer has been giving too many presentations lately, and we need to see some 
fresh blood.

At the moment we only have one proposed presentation for June (by cool-RR / 
Ram Rachum ) and he still may cancel. I've been considering to prepare a 
presentation/demo about jQuery and also proposed to give a "Bottom Up 
Subversion" presentation/tutorial. I'm not a good speaker so I'd prefer if 
someone can give it instead. We can also have a session of short, volunteered 
presentations on the spot (lightning talks or somewhat longer.).

Nevertheless, it would be preferable if someone will volunteer to give a 

#. Some logistics about the room - there is a keyboard and a projector, but no 
screen. One can connect a laptop. The computer runs Windows , and we're not 
sure if it has Windows. There's an Ethernet connection and also some Wifi 

#. Sawyer mentioned the fact that he believed that creating a branch in 
Subversion (using svn copy) was time-consuming for him ("I went to prepare 
coffee"). This sounds strange to me, because branching and tagging in 
Subversion are reportedly cheap, constant-time O(1) operations, and I've 
studied the Subversion architecture to verify it. I often branched the 
Freecell Solver's trunk which is 26M in size and it didn't take more than a 
few seconds. svn.kde.org has many branches and each of them keeps the entire 
KDE source code and is positively huge with 100s of mega-bytes of files.

#. I mentioned the mini-repository Subversion pattern - each with its own 
trunk, tags and branches which can be seen in action here:


This is a single subversion repository with several mini repositories - one 
for each project. It can be done in git too by keeping each project in its own 
sub-directory, out of the top-level sub-directory.

#. We discussed the Simple Simon solitaire -
http://en.wikipedia.org/wiki/Simple_Simon_%28solitaire%29 , which I've 
introduced Ido (ik) to and to which he became addicted lately. I've ranted a 
bit about how "Solitaire" (or what the British call "Patience games") are 
actually a generic name for single-player card games, and that what Windows 
calls "Solitaire" is actually just some variants of Klondike Solitaire.

We compared and contrasted both PySolFC ( http://pysolfc.sourceforge.net/ ) 
and KDE 4's KPatience. 

#. About 5 of us went to eat at Spaghetim after the meeting. Besides me, there 
were two Perl programmers ( http://szabgab.com/ and Sawyer, who was the 
presenter) and two Python programmers and I was appointed as the referee. We 
were able to explain some stuff from both languages to the other party. 

#. Szabgab mentioned that when he asked some people he gave training to if 
they know Perl, they said "No, I can only read it", which to him seemed to 
imply that maybe Perl's reputation as a write-only language was unfounded.

#. When we discussed Ram's Garlicsim ( http://garlicsim.org/ ) he mentioned 
that he is mostly a web contractor, but that he would prefer to be hired for 
writing simulations. Then Sawyer mentioned that often an invention brings a 
necessity, which reminded us of this book:


Very recommended. Then we discussed some other books by the same author and I 
ended up saying that I've also read this book, which I enjoyed and found of a 
similar interest to "Guns, Germs and Steel" because of its philosophy of 
taking a bird eye's view of human history:



So I enjoyed it.
