I run Wheezy Xfce 64-bit. I went through the Synaptic listings and added Python 3.3.2 and Tkinter for it, and that works fine; but for some reason PyGtk is available only for Python 2.7, not for Python 3.3, unless I'm just using the wrong way to try to find it. Is there a PyGtk available for Python 3.3 in Wheezy, and, if so, how do I install it and then import it once it's installed?
View 1 RepliesI'm currently running Debian Wheezy (upgrading to Jessie is not possible since I'm using OpenMediaVault which only supports Wheezy) but ever since I installed Deluge BitTorrent client that I've had this python-libtorrent package as "kept back". I'd like to fix this system state but how...
A few things I've tried:
Code: Select all$ sudo apt-get dist-upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done

The following packages have been kept back:
python-libtorrent

They were added through OpenMediaVault's interface when I enabled some checkboxes to be able to install Deluge.
I have tried rebuilding pygtk after installing Numpy and ended up making a mess of python. I have it back to functional now, but I would like to know how to properly add numeric python support. I suspect there is a proper order to building all of the python dependencies that yields success. Ultimately I am trying to run mypaint.
View 3 Replies View RelatedI'm on Debian Lenny. I've built and installed python-3.2 in /opt/python-3.2. Then i want to build and install pygtk, pycairo with /opt/python-3.2 and install them in that folder and not to use system default python (which is python-2.6) for their build process.
How do I tell pygtk and pycairo 's configure and makefile script to use /opt/python-3.2 's interpreter, include file and library for their build process(and not the system default python)?
I tried doing ./configure --help in pygtk folder but there was no option for specific non-system default python's folder location. Anyone has any ideas?
I have both 32 bit and 64 bit libs installed with gcc multilib.
I tried following options, but the result is still a 32bit elf:
# cc -mips64 -mabi=o64 -mlong64 -mgp64 -c gendian.c
# file gendian.o
gendian.o: ELF 32-bit LSB relocatable, MIPS, MIPS64 version 1 (SYSV), with unknown capability 0xf41 = 0x756e6700, with unknown capability 0x70100 = 0x1040000, not stripped
The machine is running 64 bit os:

Both 4.6 and 4.7 gcc have been tried, and both have the same issue.
Fixed: need -mabi=64

I am playing around with PyGTK and come across a problem: When I put a TextView inside a ScrolledWindow, and type text into the TextView until it reaches the edge, the cursor goes outside the viewport and I can't see what I'm typing. How to make it so that the ScrolledWindow automatically scrolls so that the caret in the TextView is always in visible?

On the GnomeScreensaver FAQ (here) it says to use a gsthemewindow as the toplevel window, but the libraries given are in C. Is there any way to:Import this C library to get access to this toplevel window, Convert this GTK+ C library to PyGTK, or use a pygtk app as a screensaver in some other way?

I have a code that uses the Firefox webdriver with Selenium to execute a couple javascript commands and fetch me some info. Since Debian doesn't use Firefox by default, and Selenium doesn't recognize Iceweasel as the equivalent of Firefox (which may be reasonable, but still kinda dumb), I downloaded and extracted the firefox-28.0 bz2 folder to my desktop. Next, I used the top answer suggested here to point Selenium to the binary:
Code: Select allfrom selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
[...]
binary = FirefoxBinary('~/firefox/firefox-bin')
driver = webdriver.Firefox(firefox_binary=binary)
However, it results in this error message:

I'm interested in writing a generational garbage collector in C++. This is for a Python-like programming language project. I have used Boehm's garbage collector before, but I'm worried that it will have noticeable pause times (unacceptable for interactive programs). Since I can't really find any other C++ established GCs out there, I have been thinking of simply writing my own.
However, there are two essential ingredients I need for this:
- Some kind of write barrier mechanism that will notify my collector when something is written to a part of the heap
- A way for me to know the addresses and sizes of the stack, heap and global storage (the root sets)
how to implement write barriers (and how to get the stack, heap and global storage information) on the Linux platform? As an alternative, if you know of C++ GCs other than Boehm, I would also be interested.

View 1 Replies View RelatedI'm trying to search for several strings, which I have in a .txt file line by line, on another file.
So the idea is, take input.txt and search for each line in that file in another file, let's call it rules.txt.
So far, I've been able to do this, to search for individual strings:
Code: Select allimport re
shakes = open("output.csv", "r")
for line in shakes:
if re.match("STRING", line):
print line,
How can I change this to input the strings to be searched from another file?
So far I haven't been able to.
I going through the Python course on Codeacademy. I have some trouble understanding what I'm doing wrong. This is my code below:
Code: Select alldef count(sequence, item):
total = 0
for x in sequence:
return x
if x in sequence:
total += 1
return total
print count([1,2,1,1], 1 )
The code gives me an error: "Oops, try again. Your function fails on count([1],7). It returns 1 when it should return 0."
It should be outputting 3 because 1 occurs 3 times in the list.
I have written a shared library and successfully used debhelper 9 to create a Debian package from source using a Makefile generated by cmake. I then went about writing a python wrapper to that library and wish to package that wrapper in with the library so I can have a single distributable rather than 2 separate ones.
All of my attempts so far have me placing my python source and a setup.py file in the same directory as the makefile at the time where I call debuild.
From here I have tried a couple different configurations to my debian/rules file as seen below:
Attempt 1:
# -*- makefile -*-
%:
dh $@ --with-python2 --buildsystem=python_distutils
This try seemed to package up the python stuff nicely but proceeded to ignore my makefile for the shared library and therefore ultimately failed.
Attempt 2:
# -*- makefile -*-
%:
dh $@ --with-python2
This try ran make, but completely ignored the python stuff. From some research I have gathered that the --buildsystem flag tells debuild to ignore any makefiles in the directory, which obviously causes a problem in my case.
Another attempt was to modify the build dependency to first run make and then call the python build process that file looked like this
Attempt 3:
# -*- makefile -*-
build:
dh $@
dh $@ --with-python2 --buildsystem=python_distutils
%:
dh $@ --with-python2 --buildsystem=python_distutils
This appears to somewhat work as both processes do build, but a few of the python files are still not getting installed.
Is this the way I should be going about doing this? I've noticed that most python wrappers tend to package themselves individually and then make that package dependent on the library it is attempting to wrap.
Just installed Debian 8 last night and trying to run one a few of my scripts that use easygui (a front-end for python-tk basically) and I keep getting alloc: invalid block any time a file or folder selection dialog is presented. I'm able to select a file/folder with no issues, but once the dialog closes I get a variation of what appears to be a memory error followed by alloc: invalid block.
Here's one of my scripts that does it. This one pops up a file selection dialog pretty early on to ask for a file to check, and as soon as I select any file the dialog closes and that error appears in the terminal. It happens whether I run it with Python 2 or Python 3. You will need to install python3-easygui for this script to run properly if you want to check for yourself what happens. This is a first time encountering this error for me.
Though I have developed some web applications (automation tools) using PHP which have been primarily meant for Intranet (within the organizations I have worked for), I have paid little attention to SEO (it was not required until now). But now I want to understand how do we go about implementing SEO and where do we fit this mechanism in a system / website?
Do we need any other tools or learn some specific programming /scripting language to achieve it?Will implementing a good SEO yield identical results irrespective of what search engine (be it Google or Yahoo!) is being used by users?

Options:A double linked list with fixed size character arrays. New nodes will be added when previous ones get filled. Dynamic arrays using realloc(). Linked list has the disadvantage of not having an O(1) search like an array but I think using realloc() will be more dangerous since it moves the whole block to a new location and if the new location is not big enough to hold the whole block, realloc fails !! this case will not occur with the linked list since its nodes are scattered.
View 14 Replies View RelatedI need to implement AIDE on my client machines. The builds on these machine are different, so each workstation will have its own specific db generated through running AIDE initially. It is not good practice to just leave the db on the machine, since an "attacker" would be able to view this information. However, at the same time I do not want to pull back over 100 different aide db's to the ftp server and have an update pull each specifically every time I need to run the check. The plan is to leave the db on the client machine, but encrypt it (using public/private keys). I need to be able to encrypt the file on the client machine. I will use a cron on the client to pull an update (from my ftp server) that runs AIDE. This update needs to be able to decrypt the file, use it running AIDE, then re-encrypt the file on the client.
