20 Sep '01

QuantLib-Python 0.2.0 --------------------- http://quantlib.org QuantLib-Python is a module for quantitative finance. It is a SWIG wrap of QuantLib, a C++ open source library. Version 0.2.0 of the C++ library and the Python extension have been released. The QuantLib project is aimed at providing a comprehensive software framework for quantitative finance. QuantLib is a free/open source library for modeling, trading, and risk management in real-life. Appreciated by quantitative analysts and developers, it is intended for academics and practitioners alike, eventually promoting a stronger interaction between them. Quantlib offers tools that are useful both for practical implementation and for advanced modeling, with features such as market conventions, yield curve bootstrapping, solvers, PDEs, Monte Carlo, exotic options, VAR, and so on. More complex tools such as interest rate models are next on the to-do list. What's new ------------ - added MS VC++ Project (useful for debugging and more) - added Actual/Actual classes - added day counter test - compiles with Borland free C++ compiler - Added more aliases for option types and rolling conventions - installation folders changed (for win32 and unixes) - improved default arguments - added many currencies - Added swaps to piecewise flat forward - clean compilation (no warnings) - added dividend-Rho greek - First implementation of segment integral (to be redesigned) - Knuth random generator - Cash flows, scheduler, and swap (both generic and simple) added - added ICGaussian random generator - generic bug fixes - Debian packages available URL: http://quantlib.org License: XFree86 style Categories: Miscellany Ferdinando Ametrano (ferdinando(a)ametrano.net) http://www.ametrano.net -- <P><A HREF="http://quantlib.org">QuantLib-Python 0.1.9</A> - A module for quantititative finance.

[ANN] M2Crypto 0.07 snapshot #1 - now does FTP/TLS
by Ng Pheng Siong 19 Sep '01

19 Sep '01

Hello, I am pleased to announce that M2Crypto 0.07 snapshot #1 is now available. This snapshot features the following: - FTP/TLS as specified in draft-murray-auth-ftp-ssl-07.txt. M2Crypto.ftpslib builds on Python's ftplib to provide client-side FTP/TLS functionality. (This uses blocking SSL sockets.) demo/medusa/ftps_server.py is based on Medusa's ftp_server.py and provides FTP/TLS server-side functionality. (This uses non-blocking SSL sockets and is currently the best demonstration of how to do so in M2Crypto.) Both M2Crypto client and server interoperate with each other, as well as with Peter Runestig's patched-for-TLS-and-portability OpenBSD FTP server and client. - Improved SSL connect/accept methods. (Some minor API changes to come.) - Fixed M2Crypto.m2urllib to handle HTTP redirects. Next up, FTP/TLS for ZServerSSL/Zope! This snapshot is dedicated to the innocent victims of the 0911 terrorist attacks on the US. As usual, the snapshot is available here: http://www.post1.com/home/ngps/m2/ Your feedback is appreciated. Cheers. -- Ng Pheng Siong <ngps(a)post1.com> * http://www.post1.com/home/ngps

[ANN] Narval 1.1b1
by Alexandre Fayolle 19 Sep '01

19 Sep '01

Logilab has just released Narval 1.1b1 What is Narval? Narval is a framework (language + interpreter + GUI/IDE) dedicated to the setting up of intelligent personal assistants (IPAs). An Intelligent Personal Assitant is a companion that will help you in your daily work in the information world. It runs on your machine or on a remote server, and you can communicate with it via all standard means (email, web, telnet, phone, specific GUI, etc). It executes recipes (sequences of actions) you wrote, to perform a wide range of tasks, such as prepare your morning newspaper, help you surf the web by filtering out junk ads, keep searching the web day after day for things you want, participe in on-line auctions, learn you interests and bring you back valuable information, take care of repetitive chores, answer e-mail, negociate the date and time of a meeting, and much more... It is easy to extend the built in action library by writing new actions in Python. What's new in 1.1b1? Well, first of all, we've dropped support for python 1.5.2, so you'll need python 2.1 to run this new version of Narval. Then Horn has been deeply refactored. It's still a bit slower than we'd like, but we believe it's much nicer to use; we are now using gettext for localisation of the code (a french version of the gui is available). Several internal changes have also been made in the interpreter, resulting most noticeably in speed improvements. Last, but not least, we now have a fully functionnal setup.py script, thanks to much code by Fourthought. Check the changelog (ftp://ftp.logilab.org/pub/narval/CHANGELOG) for more information. The download site is ftp://ftp.logilab.org/pub/narval/ Please keep us posted if you encounter any installation or utilisation problem.

[Application] pyproxy
by Donovan Baarda 19 Sep '01

19 Sep '01

pyproxy ------- A combined TCP and ICP to ICMP mapping proxy in Python. pyproxy is a combined TCP and ICP to ICMP mapping proxy implemented in Python. The TCP proxy is a basic TCP forwarding proxy. The ICP to ICMP mapping proxy converts incoming ICP queries to ICMP pings, returning ICP MISS responses when the ping returns. pyproxy is designed primarily to allow squid to use ICP load balancing to upstream proxies that don't allow or support ICP or UDP echo. This has already been announced on Freshmeat. This uses updated parts of Jeremy Hylton's "ping and traceroute for Python". It is also a useful example application of Python's asyncore module.

[Application] pyttymon
by Donovan Baarda 18 Sep '01

18 Sep '01

pyttymon -------- A tty usage monitor written in Python pyttymon is a simple daemon that monitors and limits usage of ttys. It is implemented in Python. A simple config file can specify monthly, daily, session, and idle limits based on tty, user, group, and ttys in use. It was inspired by timeoutd, but adds support for monthly maximums and different limits based on the number of ttys in use. This was announced some time ago on freshmeat. It is in active use, and is IMHO a fairly good example of a Python daemon, complete with /etc/init.d start/stop scripts, pid file, and logging.

Article on Python-based Web architecture
by Andrew Kuchling 17 Sep '01

17 Sep '01

I've written an article describing the Web architecture that we use at the MEMS Exchange. Comments and suggestions on it are very welcome. http://www.amk.ca/python/writing/mx-architecture/ Abstract: The MEMS Exchange (MX) project is an experiment in distributed microfabrication that needs to take advantage of the Internet in order to function. In developing the required custom software, the MX software development team faced a complex task with no clear way to figure out our requirements ahead of time. The team therefore selected or wrote tools that are simple yet still powerful and flexible, and also adopted a flexible and free-flowing methodology using some of the principles of agile programming. This paper will discuss the tools we've built and the techniques we use. --amk

SPARK 0.7 pre-release 3
by John Aycock 14 Sep '01

14 Sep '01

A pre-release of SPARK: the Scanning, Parsing, And Rewriting Kit is available for testing. At this time, I'm only distributing a new spark.py; I'm particularly interested in hearing from existing SPARK users -- there's been some major code changes, and I want to make sure I didn't break anything. SPARK features a collection of classes which can be used to implement little languages. It includes classes for scanning, parsing, AST construction, AST traversal, and tree pattern matching. The major change is that the parser runs up to twice as fast as it did in SPARK 0.6.1. The full changelog is below. Please note that the web site has moved, and my email address has changed. The new web site for SPARK is http://www.cpsc.ucalgary.ca/~aycock/spark John -- CHANGES FROM 0.7pre2 -> 0.7pre3: - GenericParser has an experimental mechanism for pickling a parser, forcing all precomputation to be performed. The result runs twice as fast as 0.6.1. CHANGES FROM 0.6.1 -> 0.7pre2: - GenericScanner's constructor now accepts an optional parameter to pass in additional flags to re.compile (in addition to re.VERBOSE). - GenericScanner's default pattern now raises an exception rather than silently swallowing input, at the request of several users. - GenericParser has had a complete rewrite, fixing a number of obscure bugs. It uses a "new" algorithm (in some sense) that runs about 30% faster than 0.6.1.
