PyQT, QProcess.readyReadStdout() problem
part of code:
>>>
try:
self.isdnlog = QProcess(self)
self.isdnlog.addArgument("/usr/bin/tail")
self.isdnlog.addArgument("-f")
self.isdnlog.addArgument("/home/aljosa/qt/isdn.log")
[...]
QObject.connect(self.isdnlog, SIGNAL("readyReadStdout()"),
self.onPhoneCall)
self.isdnlog.start()
<<<
problem is that isdnlog logs 2 or more lines per call, and QProcess
moves one line per call. is there something like
QProcess.readLastLine()?

PIL - transparent ImageDraw.text()
is it possible to create transparent text (~50% transparency) on image? i'm using the following code to draw text on image: >>> font = ImageFont.truetype(str(self.font_family)+".ttf", self.font_size) draw = ImageDraw.Draw(img) draw.text((10, 10), self.text, font=font,fill=(255,255,255)) <<< url with example would be nice 8-) Aljosa Mohorovic -- http://mail.python.org/mailman/listinfo/python-list
py2exe & qt4/qimage
i'm trying to convert python (image resizer script using PyQt4) script
to exe but support for jpeg and tiff image formats is located in
Qt4.1\plugins\imageformats (dll files) and when script is converted
exe file doesn't support jpeg and tiff.
i tryed using all file formats in
script:
tmp1 = QImage('images/type.bmp')
tmp2 = QImage('images/type.gif')
tmp3 = QImage('images/type.jpg')
tmp4 = QImage('images/type.png')
tmp5 = QImage('images/type.tif')
but it doesn't work when i convert script to exe.
any tips on howto include jpeg and tiff image formats support in exe?

capture video from camera
i'm trying to capture video from camera/webcam using python. so far i haven't found any library that would allow me to do that. cross-platform solution related to SDL/pygame would be nice but a simple solution to capture video under windows is ok.

Re: capture video from camera
i searched on google and found http://videocapture.sourceforge.net/ before i posted here. videocapture has no docs and doesn't provide additional options like motion detection nor any info on possibility of motion detection or howto implement (use of minimal system resources). i posted here to find out if anybody knows a better way to capture video.

file parsing/watching + qt
this is a Qt app. app should watch for changes in /var/log/isdn.log and on file change (like new line was added to isdn.log) it should activate event in my app. i'm trying to fetch last line in file whenever isdnlog logs something so that i can parse that line for a number and store it somewhere else, is there a standard solution for this? i'm using python2.3 on linux with PyQt3.

memory leaks - tools and docs
i've been trying to find memory leaks in a wsgi application using gunicorn to run it and after a lot of time invested in research and testing tools i did find a lot of useful information (most really old) but i'm left with a feeling that this should be easier, better documented and with tools that generate better data. if anybody can share some tips, links, docs or better tools with better reports i would really appreciate it. i'm not against paying for a good tool so any recommendation is appreciated. i mostly used http://guppy-pe.sourceforge.net/#Heapy but found http://pysizer.8325.org/ and http://code.google.com/p/pympler/ also interesting.

current week / weeks in year - best practice
i use this to find out current week and total number of weeks for
current year:
now = datetime.now()
weeks_in_year = int(date(now.year, 12, 31).strftime("%W"))
current_week = int(date(now.year, now.month, now.day).strftime("%W"))
is this the best way or is there a better way?

what if i know current context week = 20 (example), what would be the
best way to get datetime objects for first and last day of current
context week?
by "current context week" i don't mean current week for current year
but current week when program is iterating all weeks in year.

if w = current context week and now is current datetime object this
is how i calculate days:
first_day = datetime.strptime("%s %s" % (now.year, str((w-1)*7)), "%Y
%j")
last_day = first_day + timedelta(days=6)

pypi compatible software
i've been searching for a recommended way to setup private pypi repository and i've found several options: - PloneSoftwareCenter - http://code.google.com/p/pypione/ - http://pypi.python.org/pypi/haufe.eggserver - http://www.chrisarndt.de/projects/eggbasket/ - http://pypi.python.org/pypi/ClueReleaseManager so now i have a few questions: - is code behind pypi.python.org available and why i can't find some up-to-date official document or howto for private pypi repository (maybe it exists but i just can't find it)? - since python is used in commercial environments i guess they actually have private pypi repositories, where can i find docs that defines what pypi is and how to implement it? - can you recommend 1 option (software providing pypi like service) that can be easily installed and configured as a service running on apache2/mod_wsgi, has an active community and docs howto setup? - i did found http://www.python.org/dev/peps/pep-0381/ - is this the spec that above mentioned software is based upon? any additional info or comments appreciated.

naming packages for pypi
is it possible to have 2 packages with same name registered at pypi? are packages unique per name or also per category or something else? if package is unique per name how do you name you packages? do you name them something like -myapp, -myapp, -myapp, ... if this is current situation is this something that you learned to live with and there are no indications that this will eventually change?
