Reminder: Next London Python Dojo a week today
by Nicholas Tollervey May 27, 2010

May 27, 2010

Folks, Just the obligatory week's notice that the next London Python Code Dojo is happening on the 3rd June at 6:30pm at the offices of Fry-IT. Details and sign-up can be found here: http://ldnpydojo.eventwax.com/10th-london-python-code-dojo It'll be another "talks" night with several speakers presenting on subjects related to the problems, code and "features" we encountered whilst writing the adventure game (and some un-related talks too). As this is the dojo we're encouraging audience participation, questions, comments and code-along. They'll be more like seminars than lectures in style and delivery. Finally, I promise to get *MORE* pizza and beer this time round. Either, the new supplier of pizzas produce better pizza so more were eaten OR their pizzas are smaller than the old place. In any case, we'll be snowed under with pizza this time round. Pizza delivery is at 6:30pm. If you want any, get there before Bruce does (he has two dojo's worth of pizza to get through). Looking forward to it, Nicholas.

Next Cambridge & East Anglia Meeting: Tue 8th June
by Tony Ibbs May 20, 2010

May 20, 2010

As discussed on the CamPUG google group, the next meeting will (again) be delayed, mainly because of people being on holiday. As it says there: Assuming this is OK with Tom and Robin, the next meeting (which should be a Code Dojo meeting) will be: 7.30pm, Tue 8th June at RealVNC (http://tinyurl.com/realvncoffices). The meeting after that (back on schedule) should be Tuesday 6th July. EuroPython is then 19th - 22nd July. I think we *should* be OK to hold the meeting after that on Tuesday 3rd August, but I shall be away on holiday (again!). Hope that all makes sense... Tibs

10th London Python Code Dojo
by Nicholas Tollervey May 10, 2010

May 10, 2010

Folks, The next London Python code dojo will take place on Thursday 3rd June at 6:30pm. You can find out here and book your place here: http://ldnpydojo.eventwax.com/10th-london-python-code-dojo After five dojos of building an adventure game we all decided to take a break and organise a “talks” night (with some of the talks discussing adventure game related stuff). Don’t let this fool you into thinking it’ll just be a sequence of presentations: because of the participatory nature of the dojo we encourage attendees to interrupt, ask questions, code along and generally interact with what’s going on. Think of it more as a set of seminars rather than presentations. So what about the talks..? (In no particular order and subject to change): • Tim Golden – Pyro (http://pyro.sourceforge.net/) • Dave Kirby – Twisted (http://twistedmatrix.com/trac/) • John Ribbens – john.py (a web framework) • Andy Kilner – CMD (http://docs.python.org/library/cmd.html) • Nicholas Tollervey – Fluiddb (http://fluidinfo.com) • Tom Dunham – The bayesian problems encountered in the adventure game Pizza and beer start at 6:30pm and the talks themselves will start at the earliertime of 7-7:15ish. We aim to finish 9:30ish. Photos from the 9th Dojo can be found here: http://www.flickr.com/photos/11306102@N05/sets/72157623906491735/ Free pizza and beer will be provided. (Thanks Fry-IT) Participants get the chance to win a cool book (thanks O’Reilly). Look forward to seeing you there! Nicholas.

Bayesian filter
by Carles Pina i Estany May 7, 2010

May 7, 2010

Hello, (scroll to PYTHON TEST for a test) I've took another look to the Bayesian filter (it was not my "task" :-) but it's my pleasure). Ok, to start, Reverend tokenizes the training texts and works only on token level, not sub-token level. So we should not expect that will detect c0mputer as computer (quite common mistake yesterday, I think) (I was doing a high-level mathematical description, but I will postpone -for when I will check some more things- or just leave for the Pythoner who will do it for the next Meetup ;-) ) PYTHON TEST carles@pinux:~/bayes$ ls training/ bash c++ python Each of these directories contains between 18 and 29 files that I've copied randomly from different places of my hard disk. Then I have: carles@pinux:~/bayes$ ls guessing/ demanar.py keymap.sh medium.py qdacco.cpp carles@pinux:~/bayes$ some other files that I've copied there... The Bayesian filter never knows the name of the file. Just using this set for training, look the results: ----- Start test ./guessing/qdacco.cpp [('c++', 0.6590693537529797), ('python', 0.59287521198182513), ('bash', 0.28091954259046653)] ./guessing/demanar.py [('python', 0.58882188718297557), ('c++', 0.57869106382644175), ('bash', 0.36380374534210203)] ./guessing/keymap.sh [('bash', 0.54270073170250122), ('c++', 0.47142124856042872), ('python', 0.36321294599284148)] ./guessing/main.py [('python', 0.65909707358336711), ('c++', 0.52731742496139433), ('bash', 0.3261511618248264)] I consider it quite good. bayes.py is 30 lines long -could be less- and it works pretty well, even having only parts of the program (don't tell me to check for #include , #!/bin/bash or #!/usr/bin/python, not needed at all, works with snippets of code, etc.) Yes, there is one case that guess that it's Pythonn and not far from c++. I probably need a bigger data set, but even then if it guess it "quite well" then is "quite good" :) (I'm thinking, for example, in some service like pastebin, that would guess that the code that you are copy-pasting there, and if you change the guess, it can train itself with the new code). My training sets are very noisy, and I should subclass Reverend and improve the tokenizer to use a a separator "=", "(", ")" and other things, since now a line like: linia=random.randint(1,float(total_paraules)) It's one token... The literals should be probably removed as well. I'm taking a look to the statistics part. Here is a good start: http://en.wikipedia.org/wiki/Naive_Bayes_classifier Cheers, -- Carles Pina i Estany http://pinux.info
