ButtonBar Windows Utility - ButtonBar.py
by philrist＠comcast.net Feb. 28, 2012

Feb. 28, 2012

This program produces a buttonbar controlled by an initialization file simular to that used by qeditor. Users can set button colors, change the working directory, set environment variables and execute arbitrary programs during startup. Any of these commands and the commands associated with the buttons can contain macros which are expanded by the Do or Do2 programs. Commands can also contain macros that expand to commands from a files context menu. begin 644 ButtonBar.py M)R<G#0H[(W1E;7!… [View More]

[RELEASED] Release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3
by Benjamin Peterson Feb. 25, 2012

Feb. 25, 2012

We're pleased to announce the immediate availability of release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3 . The main impetus for these releases is fixing a security issue in Python's hash based types, dict and set, as described below. Python 2.7.3 and 3.2.3 include the security patch and the normal set of bug fixes. Since Python 2.6 and 3.1 are maintained only for security issues, 2.6.8 and 3.1.5 contain only various security patches. The security issue exploits Python's dict and … [View More]set implementations. Carefully crafted input can lead to extremely long computation times and denials of service. [1] Python dict and set types use hash tables to provide amortized constant time operations. Hash tables require a well-distributed hash function to spread data evenly across the hash table. The security issue is that an attacker could compute thousands of keys with colliding hashes; this causes quadratic algorithmic complexity when the hash table is constructed. To alleviate the problem, the new releases add randomization to the hashing of Python's string types (bytes/str in Python 3 and str/unicode in Python 2), datetime.date, and datetime.datetime. This prevents an attacker from computing colliding keys of these types without access to the Python process. Hash randomization causes the iteration order of dicts and sets to be unpredictable and differ across Python runs. Python has never guaranteed iteration order of keys in a dict or set, and applications are advised to never rely on it. Historically, dict iteration order has not changed very often across releases and has always remained consistent between successive executions of Python. Thus, some existing applications may be relying on dict or set ordering. Because of this and the fact that many Python applications which don't accept untrusted input are not vulnerable to this attack, in all stable Python releases mentioned here, HASH RANDOMIZATION IS DISABLED BY DEFAULT. There are two ways to enable it. The -R commandline option can be passed to the python executable. It can also be enabled by setting an environmental variable PYTHONHASHSEED to "random". (Other values are accepted, too; pass -h to python for complete description.) More details about the issue and the patch can be found in the oCERT advisory [1] and the Python bug tracker [2]. These releases are releases candidates and thus not recommended for production use. Please test your applications and libraries with them, and report any bugs you encounter. We are especially interested in any buggy behavior observed using hash randomization. Excepting major calamity, final versions should appear after several weeks. Downloads are at http://python.org/download/releases/2.6.8/ http://python.org/download/releases/2.7.3/ http://python.org/download/releases/3.1.5/ http://python.org/download/releases/3.2.3/ Please test these candidates and report bugs to http://bugs.python.org/ With regards, The Python release team Barry Warsaw (2.6), Georg Brandl (3.2), Benjamin Peterson (2.7 and 3.1) [1] http://www.ocert.org/advisories/ocert-2011-003.html [2] http://bugs.python.org/issue13703 [View Less]

Fast Code with the Cython Compiler ++++++++++++++++++++++++++++++++++ In-depth coverage of Cython with Cython core developer Stefan Behnel. No question about writing extensions and using external C libraries with Cython should remain unanswered after this day. Numerical Calculations with NumPy +++++++++++++++++++++++++++++++++ NumPy is the way to work with multi-dimensional numerical arrays in Python. It is fast and provides a high-level programmer interface. This course day teaches you all the basics. Fast NumPy Processing with Cython +++++++++++++++++++++++++++++++++ Working with NumPy you need to avoid loops over arrays to make your code fast. While NumPy provides indexing and other techniques to help you here, some types of algorithms are easier expressed with loops. Combining NumPy with Cython you can write fast loops. Another topic is parallel programming with OpenMP to take advantage of multi-core CPUs that become so common place these days.
