You are invited to join the Compiler SIG: http://www.python.org/sigs/compiler-sig/ The Web pages about the SIG still need a lot of work, but they provide some indication of the SIG's purpose: This SIG provides a forum for discussing compilation and program analysis issues. Unlike most SIGs, it does not have a specific mandate or deliverable. There are several independent projects to develop compilers, type checkers, and related tools. Ka-Ping Yee took notes on the Dev Day session on compilers. It provides more background about the SIG: http://www.python.org/sigs/compiler-sig/dev-day-notes.txt I am putting together a list of Python compiler and program analysis projects. If you are responsible for such a project, I'd appreciate it if you could send me a URL and a brief description. I'll post the final list on the compiler-sig Web page.

Python CVS available via the Web

by bwarsaw＠python.org

The very latest CVS snapshot of the Python source code is has been available by anonymous CVS for a while now. See http://www.python.org/download/cvs.html for details. Just van Rossum reminds me that I forgot to announce that I've also installed Greg Stein's excellent ViewCVS tool so you can get Web access to the CVS repository for Python (and JPython, Mailman, Distutils, XML-SIG, and CC Mode). Visit http://cvs.python.org/ to take a look. It won't be very fast though; it's running on a pretty old machine.

Dr. Dobb's Python-URL! - weekly Python news and links (Feb 3)

by Fredrik Lundh

The eff-bot finally makes it back from the Python conference, after an involuntary detour to Oslo. Here's this weeks' Python-Alert, worth well over $9.52 per week: First, a couple of reminders: Don't forget Software Carpentry's design competition: http://software-carpentry.codesourcery.com/contest-rules.html Don't forget the www.python.org design competition: http://www.python.org/Redesign.html And don't forget the O'Reilly Python Conference: deadline extended to at least Feb 15: http://conferences.oreilly.com/oscon2000/call.html The eighth Python conference (SPAM8) was a huge success. Almost everyone was there, except Tim Peters. He might be real, though -- at least two usually reliable sources told me they'd met him in real life. Here're interesting links: http://www.oreilly.com/frank/index.html (frank willison) http://starship.python.net/crew/amk/diary (andrew kuchling) http://freeweb.pdq.net/robinf1/spam8pix/ (robin friedrich's photo album) http://www.python.org/workshops/2000-01/ (conference site) http://www.reiters.com/ (official conference bookstore) http://www.cravindogs.com/about.html (python powered, sort of) In other news: ActiveState (www.activestate.com) joins the Python Consortium, and announces great plans for Python. David Ascher has more info on this: http://www.egroups.com/group/python-list/77941.html http://www.activestate.com/press/releases/python.htm Secret Labs AB (www.pythonware.com) joins the Python Consortium, and also receives first round of venture funding from the East Sweden Foundation of Entrepreneurship and Technology Transfer. People keep releasing cool software: Christian Tismer's übercool stackless python: http://www.tismer.com/research/stackless/ Barry Warsaw announces JPython 1.1 final: http://www.jpython.org/NEWS Andreas Jung releases PMW (Poor Man's Zope): http://www.suxers.de/pmz.htm More books arrive: Python and Tkinter Programming (by John Grayson) http://www.deja.com/getdoc.xp?AN=575925861 http://www.manning.com/grayson/ Python Programming for Win32 (Andy Robinson & Mark Hammond) http://www.oreilly.com/catalog/pythonwin32 (both books mention my name, so they can't be that bad ;-) Btw, judging from what people told the eff-bot at SPAM8, at least four more books are in the works. And if you want to write your own Python book, Greg Wilson has some great ideas for you: http://www.deja.com/getdoc.xp?AN=579589266 Finally, the Scheme folks reveal the truth about Python and Pythoneers, but completely fails to start another flame war.

pxDislin - release 0.3

by Paul M

DESCRIPTION: ----------- pxDislin is an object-oriented wrapper around the DISLIN plotting library. DISLIN is a powerful and flexible multiplatform (Win32, Unix, Linux, etc.) library designed for displaying scientific data. DISLIN's author, Helmut Michels, has made available a DISLIN plotting extension for the Python programming language (see http://www.linmpi.mpg.de/dislin/ for more details). pxDislin provides a set of classes which represent various aspects of DISLIN plots, as well as providing some easy to use classes for creating commonly used plot formats (e.g. scatter plots, histograms, 3-D surface plots). A major goal in designing the library was to facilitate interactive data exploration and plot creation. Documentation and a demo program are included. The library has been tested on WinNT and FreeBSD, but I anticipate that it should work on any platform which can make use of Python, NumPy, and the DISLIN python extensions. Feedback, comments, and critique are gladly accepted (email: paul.magwene(a)yale.edu). VERSION: ------- This is release 0.3 of pxDislin. WHAT'S NEW? ----------- -- Almost complete coverage of useful plot functions in the DISLIN library. -- Support for legends. -- New attribute setting mechanisms to improve functionality in interactive seesions. URL: ---- You can find pxDislin at: http://pantheon.yale.edu/~pmm34/pxdislin.html Paul Magwene paul.magwene(a)yale.edu <P><A HREF="http://pantheon.yale.edu/~pmm34/pxdislin.html">pxDislin 0.3</A> - a set of object-oriented classes which work with the DISLIN python extension.

by Mike Pelletier

G'day, Zope Weekly News is a digest of some of the useful and interesting events which have occurred on the various Zope mailing lists and the Zope.org site. It is published each Wednesday evening. Any opinions contained in the Zope Weekly News are those of the chronicler exclusively. Suggestions for ZWN items are happily accepted. Please mail them to <mike(a)digicool.com>, put 'ZWN' somewhere in the subject and remember to include URLs. Announcements * ActiveState has announced it will be offering industrial-strength commercial Python support. ActiveState is renowned for their Perl support and development tools. The press release, linked below, includes comments from Paul Everitt. http://www.activestate.com/press/releases/python.htm * Frank Wilson, editor-in-chief at O'Reilly, presently has quite a lot of commentary on the IPC8, Python, Zope and Digital Creations in his "Frankly Speaking" column. http://www.oreilly.com/frank/ * O'Reilly recently launched their new portal, O'Reilly Network. The prestigious first feature is an interview with Paul Everitt, which explores some of the hidden gotchas and bonuses of opening up your software. The interview is available as text and three flavours of audio: High bandwidth RealAudio, low bandwidth RealAudio, and MP3. Nice! http://www.oreillynet.com/ http://www.oreillynet.com/pub/a/network/2000/01/25/interview/index.html * You can now follow ZopeStudio (aka the Zope-Mozilla Initiative) as it evolves by tracking the new ZopeMozilla CVS. For more information, see: http://lists.zope.org/pipermail/zope-announce/2000-January/000102.html * The Zope Portal Toolkit (PTK) is now a Real Live Product, and is also avalialable to be tracked by CVS. See the post in the zope-ptk(a)zope.org list. http://lists.zope.org/pipermail/zope-ptk/2000-February/000111.html * Chris McDonough <chrism(a)digicool.com> reported ZDNet UK's analysis of open source application servers Zope and Midgard. http://www.zope.org/Members/mcdonc/Links/zdnetuk-appserver * Trey Seaver <tseaver(a)palladion.com> announced the commencement of the Zope Guru of the Week "contest". Trey even made the application handling the ZGotW downloadable. http://zope.palladion.com/demos/ZGotW * "jwashin" submitted a "ZClasses Survey/quiz product". It is still undergoing development, and contributions are welcome. http://www.zope.org/Members/jwashin/Survey * Geeknews.org published an interesting interview with Rick Collette, head developer for SPIRO Linux. In it, Rick explains the reasoning behind including Zope as a distribution component. http://www.geeknews.org/features/interviews/spirolinuxinterview.html * Linux Weekly News offered the following link to ZopeNewbies' coverage of the IPC8 and it's Zope Track. Photos! http://weblogs.userland.com/zopeNewbies/ New Releases * Zope 2.1.3 has been released. This update contains fixes for a race condition that could cause Zope to hang on very high-traffic sites, two database packing bugs, and a bug that caused Zope to sometimes hang instead of shutting down when the shutdown function was accessed over a very fast network. http://www.zope.org/Products/Zope/2.1.3/ * "ngps" announced the availability of a very exciting product, "M2Crypto", which allows ZServer (and so Zope) to speak SSL natively. http://www.zope.org/Members/ngps/m2crypto_news * RainDog submitted version 0.0.1 of TTImage. TTImage renders arbitrary text to images on-the-fly. http://www.zope.org/Members/RainDog/TTImage * "haqa" has contributed "Favourite Links", a ZClass-based product which presumably manages a collection of links. http://www.zope.org/Members/haqa/ZLinks Updates and Patches * "kslee" contributed Zope patch which allows you to select from a list of default contents when creating a DTML Method/Document. http://www.zope.org/Members/kslee/DTML_Repository_Patch * "faassen" released version 0.2 of ZFormulator. http://www.zope.org/Members/faassen/ZFormulator/ * "phd" announced that mod_pcgi2 has reached version 1.0.0. http://www.zope.org/Members/phd/mod_pcgi2 * "jephte" updated jcNTUserFolder to version 0.0.2. http://www.zope.org/Members/jephte/jcNTUserFolder * "kslee" spent some time hacking on ZCatalog's splitter.py and the result was Voodoo Kludge Splitter. The splitter is what determines word breaks for full text searches. The Voodoo Kludge Splitter allows full text searches of non-ASCII content, such as Korean, Japanese and Chinese. There are caveats to be aware of. http://www.zope.org/Members/kslee/VoodooKludgeSplitter/ * Evan Simpson <evan(a)4-am.com> has brought his SiteAccess product up to version 1.0.0. This is the first stable release. SiteAccess allows you to use virtual hosting to make non-root Zope objects appear to be the root of your website. http://www.zope.org/Members/4am/SiteAccess * "htrd" contributed a Zope hack which "provides support for wide character strings in ZPublisher, property pages, and property sheets." http://www.zope.org/Members/htrd/wstring * "jules" contributed a HowTo which describes the creation of "Smarter" forms. The idea is to prevent the user from ever having to go "Back" by representing forms with prior inputs already filled in. http://www.zope.org/Members/jules/smarterforms_html/smarterforms_html * Another HowTo from "jules", this one describes auto-starting Zope on boot on a SuSE 6.3 system. http://www.zope.org/Members/jules/SuSE-6.3_html Zope.org items * Chris Petrilli <petrilli(a)digicool.com> has made all the slides from the tutorials he offered at the Zope Track of IPC8 available online. http://www.zope.org/Members/petrilli/Presentations/ * "kusako" contributed a Tip which explains how to catalog a group of properties as though they were one. http://www.zope.org/Members/kusako/AdvancedCataloging * Miklos Nemeth <nemeth(a)iqsoft.hu> submitted "How-To: Using Emacs with Zope on RedHat 6.1". It appears to walk the user through using Emacs as a Zope development environment. http://www.zope.org/Members/nemeth/usingEmacsWithZope * "rbickers" wrote an excellent HowTo on Running Zope on BeOS. The HowTo includes links to a suitable Zope binary. http://www.zope.org/Members/rbickers/Zope_on_BeOS * Continuing a thread, Jeffrey Shell <jeffrey(a)digicool.com> wrote a similar HowTo for MacOS X. http://www.zope.org/Members/jshell/buildingZopeOnMacOSXServer * "jephte" submitted a HowTo describing how to make Zope work in remote user mode (this is, making the webserver deal with Authentication) in conjunction with IIS. http://www.zope.org/Members/jephte/HOWTO/IIS_and_Zope_in_REMOTE_USER_mode * Chris Pertilli <petrilli(a)digicool.com> has started a Z SQL Method FAQ. He is accepting additional questions and answers. http://www.zope.org/Members/petrilli/ZSQLFAQ * Chris McDonough <chrism(a)digicool.com> wrote an EXTENSIVE HowTo describing the process of installing Zope and upgrading an existing Zope installation, complete with screenshots. If you are having difficulty getting Zope off the ground, this looks like the place to start. http://www.zope.org/Members/mcdonc/HowTos/zopeinstall/ZOPE-INSTALL-HOWTO * Miklos Nemeth <nemeth(a)iqsoft.hu> also contributed a HowTo about using the SQL Sessions product. SQL Sessions allows you to store arbitrary per-visitor state in an SQL database. http://www.zope.org/Members/nemeth/usingSQLSession * John Udell <udell(a)monad.net> wrote "How-To: A <dtml-calendar> example", which demonstrates managing per-date data with the <dtml-calendar> tag presenting the interface. http://www.zope.org/Members/judell/CalendarTagExample * "anthony" submitted "How-To: Choosing to store data in SQL vs ZODB". In it, he supplies a number of questions you can ask yourself to determine whether to keep application data in the Zope database or an external one. http://www.zope.org/Members/anthony/sql_vs_ZODB * Miklos Nemeth <nemeth(a)iqsoft.hu> has written another HowTo targeted at RedHat 6.1 users: "Zope and Apache on RedHat 6.1". http://www.zope.org/Members/nemeth/howtos/zopeandapacherh61 * Another Chris McDonough <chrism(a)digicool.com> HowTo: "Using the Zope Debug Log to Track Down Hangs". This HowTo includes a log file analyser. http://www.zope.org/Members/mcdonc/HowTos/DEBUG-LOG * Jim Fulton has made three of his IPC8 presentations available.
