Sean McGrath: IronPython cometh [«Jim Hugunin, the daddy of both IronPython (Python for the .NET CLR) and Jython (Python for the Java JVM) demos IronPython. You need a dynamic programming language. You work in both .NET and JVM environments. You want to learn one bag of tricks and use it in both. BUT you want to know that you can step out of the box and access the .NET environment in its entirity (GUIs, .NET libs etc) and the Java environment (Swing, Beans and what not) in their entirity when you need to. One word: Python.»]

Django Weblog: Django at PyCon [«The next PyCon, to be held in Dallas in February 2006, will feature two Django talks: Django tutorial, by Jacob; Using Django to supercharge Web development, by me. Also, the "Agile Documentation: using tests as documentation" session will present Django's automatically-generated documentation/testing system.»]

Zope Dispatches - Paul Everitt: Planet Plone, up and running [«Forgot to mention: the land of Plone now has a weblog feed aggregator, collecting blog entries from a number of Plone folks. ... Joel Burton and I are sharing a weblog called From the Collective, a place for us to talk about the Plone Foundation activities.»]

online.effbot.org - Fredrik Lundh: simple generator-based parsing [«I just (re)discovered a rather efficient and straightforward way of writing recursive-descent parsers in Python. Here's an outline: 1. use an iterator to split the source into a stream of tokens or token descriptors. 2. pass the iterator's next method and the first token to the toplevel parser class. when you call functions corresponding to individual grammar rules, pass in the same method and the current token. 3. to check the current token, inspect the token argument. to fetch the next token, call the next method.»]

Small Values of Cool - Simon Brunning: London Web Framework Night [«Speaking of the London Web Framework Night - I never did write that up, did I?»]

Ian Bicking: Dynamic __doc__ [«One thing I did in the last (0.4) release of FormEncode is add some dynamic docstrings. I've started relying more heavily on automatically-generated documentation, but there was information specific to validators that I wanted to include without the tedium or redundancy of copying it into the docstring. In particular, I wanted to display information about all of the error messages a validator can produce.»]

Cheese Shop: dap 2.1.0.rc1 [«DAP (Data Access Protocol) client and server for Python.»]

Marko Samastur: Building FAQ from wiki pages [«We use MoinMoin for all our documentation needs, since it simplifies almost all related tasks. It's nice when everything is available at one place through a familiar and easy to use interface. This is why I also wanted to use it to build a FAQ for our site, which is more needed with each day. There's an abundance of software for building and managing such documents, but I haven't found anything that would match our needs. ... At the end I decided to build our own thing using Beautiful Soup, a python package I raved about a while ago.»]

Mike Fletcher: Slides for this evening [«Okay, the slides for the presentation are now up.»]

Small Values of Cool - Simon Brunning: London Python/Django/Ruby/Rails/Java Christmas party [«Not content with a Python/Django/Ruby/Rails meetup, Sam, Jez and I have teamed up to throw a Python/Django/Ruby/Rails/Java Christmas party this year. (For "party", read "bunch of nerdy blokes, many with beards, standing around drinking beer and chatting about computers".) It's at The Old Bank of England, Fleet Street on the evening of December the 12th.»]

Mike Fletcher: For the ravening OpenGL-ctypes hordes [«Prepping for mini-talk tonight on OpenGL-ctypes I've just been installing it to Tim's laptop. Came across a few shallow bugs along the way...»]

a contest open to various programming languages (including Python) [«The second edition of the programming contest TopDev2006 will take place on January 28th-29th 2006. This contest is original by its independance from any languages. The winners will not be the fastest programmer, but the ones who will propose the greatest technical solution with the most complete documentation.»]

James Tauber: Atom (and Demokritos) Status [«Tim Bray has a nice summary of how the Atom Publishing Protocol works and a note on the current status. On the weekend I worked more on my Python implementation of said protocol, Demokritos. I'm close to an initial release which won't be usable as a real Atom server yet but should be good enough for interop testing.»]

Cheese Shop: NewEdit 3.1 [«Editor based on wxPython»]

Groovie: Routes 1.0 Released [«I've finally finished the documentation for Routes and as I mentioned earlier regarded releases am now ready for a 1.0 release.»]

Zope Dispatches - Paul Everitt: Florent mega rocks [«On his blog, Chris points out the amazing things Florent Guillaume has been doing lately. It isn't just the things he is doing. It is also the way he is doing them. He takes a LOT of extra time to explain things to people, in a very well-written way, and even covers backwards compatibility issues.»]

Titus Brown: Ooh, ooh, I've got an ORM! [«I'm deeply skeptical of Jeff Watkins' approach to ORMs ... For example, why the heck would "No Magic" be on the list of anyone using Python?»]

Titus Brown: OCaml the Python way [«Cute.»]

Mike Fletcher: Pythonic duct tape [«I spent much of the day working on CDR billing-data import for the VoIP project. This is pretty simple stuff, download the records, load them, unify them with the ids in the database, and then insert records to record the charges. It just takes forever. Lots of trivial little bits that need to be dealt with to deal with corner cases, error checking to recover from data failures, all that wonderful stuff.»]

Richard Jones' Stuff: Open Source Developers' Conference fast approaching [«I've been hella busy lately, as I've taken over the role of organising the program for OSDC in December. I'm currently putting the finishing touches on the proceedings, which are looking both pretty and good value. The presentations timetable is up too. There's a really good spread of talks both about Python and related technologies like the web, databases, linux and so on.»]

Max Khesin: Ruby closures piss me off [«But they apparently piss off Matz, also ... I previously observed the same problem in Python; and while some try to brush it under the table, others get the point.»]

Grig Gheorghiu: Python Testing Tools Taxonomy [«There's been a flurry of blog posts recently on the subject of Python testing, especially on Web application testing tools. I thought it would be a good idea to put up a Wiki page with the tools I know of, so that anybody who's interested in contributing to the "Python Testing Tools Taxonomy" can do so easily.»]

Zope Dispatches - Paul Everitt: Marc from Cocoon, a class act [«A cross-Europe hat's-off to Marc from Cocoon-land. A sales guy from Tridion pinged him for "ny doubts, uncertainties, fears there are about using" Plone. I really liked the points Marc made afterwards, as well as the comments: "people start using FUD when they can no longer win the business on their own strength." I wonder if OSCOM.org should start a petition, where each open source CMS signs up for a pledge to do for each other what Marc did for Plone.»]

Titus Brown: On a somewhat separate note... Python docs [«Submitting patches to Python is a huge pain, because of all of the overhead and review process. (And the sourceforge bug/patch system is really, really lousy.) This process is certainly legitimate for code, but I think it's overkill for documentation -- especially when you consider how the standard library has grown, and how poor the documentation is in some of the places I frequent (urllib2 , anyone?) One possible solution? I've been thinking setting up a Trac site and a darcs repository for editing Python documentation.»]

Chris McAvoy: Routes Docs Online [«Ben Bangert posted documentation for his Routes package. It's a great looking package from what I've seen so far. I haven't had a chance to play with it, but I get the impression it's going to be very useful. URL translation to controllers is a pretty useful tool.»]

Efectos Especiales: How to exit [«As seen in these comments: "Here's some complementary stupidness: If you enter "quit" or "exit" in the Python interpreter, it will respond with "Use Ctrl-D (i.e. EOF) to exit."" That is indeed annoying, but I figured there would be a good reason for it.»]

Cheese Shop: Karrigell 2.2 [«A simple and full-featured web framework»]

Chris McAvoy: Django / Rails Presentation is Go! [«In a very positive move, ChiPy, the Chicago Ruby Users Group, the DePaul Linux Users Group, and the DePaul Computer Science Society have teamed up to bring David Heinemeier Hansson (creator of Rails ) and Adrian Holovaty (one of the creators of Django ) together for Snakes and Rubies! ... This has been a theme for me over the past couple of months, trying to emphasize where the local users groups are the same, instead of encouraging little language wars.»]

Chris McAvoy: November ChiPy Meeting [«Last night's meeting worked out well, despite it's relatively last minute nature. The three presentations (Ian Bicking on RulesDispatch, Robert Ramsdell on the random module, and Fawad Halim on PYRO) were great.»]

Sidnei da Silva: GPL Considered Harmful? [«Had a quick chat with Paul Everitt this morning, which to my surprise informed me that people out there are bitching about Plone's license which happens to be GPL.»]

nerd.newburyportion - Jeff Watkins: Querying the Context [«An important part of any ORM is being able to easily query the objects contained in the database. Not every ORM handles this particularly gracefully. ... One of the goals for the querying facility within my ORM library is the ability to cleanly perform multiple queries.»]

nerd.newburyportion - Jeff Watkins: Counting Pythons In My Sleep [«One of the things I really like about JavaScript and Java is the fact that they use garbage collection rather than reference counting. I just discovered that Python also uses reference counting, but includes a garbage collector. From my primitive tests, the garbage collector doesn't seem to be turned on by default.»]

nerd.newburyportion - Jeff Watkins: Everybody's Got An ORM [«SQLObject differs significantly from other ORMs I've used, like Hibernate and CoreData. My goals for an alternative ORM are the following...»]

nerd.newburyportion - Jeff Watkins: Identity Sample [«Enough folks have had trouble getting the TurboGears identity framework to work that I thought I'd share the project I've been using to test various features as I add them.»]

nerd.newburyportion - Jeff Watkins: Half-baked CherryPy [«As part of my work on the Identity framework for TurboGears, I've had to write a filter for CherryPy. While I'm certain the team building CherryPy is well meaning, I doubt whether there's a coherent design in place. For example, because CherryPy doesn't allow filters to catch and handle exceptions thrown, er, raised by the controllers, I've had to resort to throwing, er, raising an InternalRedirect exception which is somewhat strange.»]

nerd.newburyportion - Jeff Watkins: Identity Management for TurboGears [«I just committed the code for the TurboGears identity management support (revision 89). And because this is such new code, I thought it might be helpful to include a short How To for getting everything up and running.»]

Zope Dispatches - Paul Everitt: Zope and the GPL [«I'd like to collect some input on a meme that has gone around: is Plone a "bad" Zope citizen for using the GPL? Sidnei and I chatted about this point a bit. Below are my thoughts and Sidnei wrote a weblog post with his thoughts.»]

Release of simulation package SimPy 1.6.1 [«It is our pleasure to announce the release of version 1.6.1 of the SimPy discrete event simulation package.»]

OSDC::Israel Conference 26-28 Feb. 2006 [«Open Source Developers' Conference, 26-28 February, 2006, Netanya, Israel. Announcement and Call for Papers ... The Israeli OSDC is organized by the Israeli Perl Mongers and the Israeli Python user group. Our aim is to bring together practitioners, scholars, students, programmers, researchers and managers from different areas to discuss their views on various aspects of the Open Source technologies, to share knowledge and to have fun while doing so.»]

python-dev Summary for 2005-10-01 through 2005-10-15

splee.blog - Lee McFadden: TurboGears Dev Chat transcripts [«... dev chat in #turbogears ... was mainly a run down and discussion of the new features in development for TurboGears 0.9 and the highlighting of certain trac tickets that need to be fixed for 0.9. Lots of interesting stuff was brought up about the new Widgets for on-the-fly generation of forms, especially as widgets are, IMHO, the most exciting addition to the TG world.»]

The Cog: TurboGears FAQ [«Check out the "Unofficial" TurboGears FAQ on the TG Trac. Please consider contributing your experiences to help ease the pain for others.»]

Toronto Python User's Group (PyGTA) meeting this Tuesday [«We will again be holding PyGTA at the Linux Caffe at 7pm this Tuesday. If no one else stands up to suggest a topic I'm thinking I'll discuss/show the OpenGL-ctypes work I've been doing on and off for the past few months.»]

The Cog: Simple pager decorator [«I've done a simple pager decorator some time ago, and I was planning to comment it here, but I wanted to polish it a little.»]

splee.blog - Lee McFadden: TurboGears Torrents [«I've set up a few .torrents for the turbogears community. The first is the 20 Minute Wiki screencast and the second is the new TurboTunes screencast. Beware of the second screencast as it shows (currently) unreleased features and you won't be able to replicate it with the 0.8a4 release.»]

The Cog: Enabling Sessions [«CherryPy, for version 2.1, has changed their system for using sessions. It's actually rather easy to use!»]

Kudos to Chris McDonough, as well! [«Chris has been steadily at work this week on finishing his Basket product, which makes it possible to distribute Zope add-ons using Phillip Eby's "eggs".»]

Cheese Shop: pullparser 0.0.7 [«Pull API for HTML parsing.»]

Titus Brown: Unit tests save my butt [«Just updated twill to the latest versions of the wwwsearch/mechanize code. Because twill reaches moderately far into the wwwsearch code, some of the internal changes that John Lee made to mechanize affected the functioning of twill adversely. Conveniently, my unit tests caught many problems and I could iterate through & fix them one by one.»]

Ned Batchelder: My personal Python mind set [«I was talking to a fellow Python enthusiast the other day, and the topic came up of Python's great dynamic nature. I said that I didn't think it had had that big an effect on me. He was surprised. "You don't like dynamic typing?" he asked. It's not that. Looking back over my experience with Python, it's not the dynamic typing that has affected me most.»]

PPCEncoder 4 PocketPC [«I have written a nice Multimedia re-encoder (PPCEncoder) in Python. It re-encodes movies to PocketPC format.»]

David Keeney: Philadelphia PUG [«Philadelphia has a new Python User Group, and we are looking for members and speakers. If you are in the greater Philadelphia area, take a look at our mailing list at yahoo group PhillyPUG.»]

Cheese Shop: enum 0.2 [«Robust enumerated data types in Python»]

Cheese Shop: pyemf 2.0.0b1 [«Pure Python Enhanced Metafile Library»]

Max Khesin: off-track [«So far I have one specific peeve about Rails that might make developing an app in it a very annoying for me. ... Rails requires you to define your objects in SQL. ... Switching databases could happen for business reasons; another common practice is using SQLite for development and switching to some heavy SQL in deployment. Having to commit to an SQL flavor up front is going to make this difficult. ... For small apps that I am interested in and that represent most of Ruby's target audience, simple representation using objects for data and some metaprogramming for data relatonships would be more than sufficient. SQLObject, I'll take 2!»]

Issue Dealer 0.9.93 released [«»]

The Dreamer: Memories of Linux Bangalore 2003 [«... Yahoo! ... asked me to send my resume. So, I thought, sure, why not. Then, I got into the programming tests. After that, there was the programming round where I was asked to write a shell. I was happy that they gave me a problem which I actually had some clue about. I was asked to implement program execution, tab completion and a history, and was given any choice of language (the platform had to be FreeBSD though), and about 3-4 hours of time. So, I chose Python and although they were surprised, they asked me to go ahead. ...»]

CMF 1.5.5 released [«The CMF developer community and Zope Corporation are pleased to announce the release of version 1.5.5 of the Zope Content Management Framework (CMF). This release marks the latest stable release in the CMF 1.5 series and should be suitable for production use.»]

Plone Shell and post mortem debugging [«Was playing around with Plone Shell a lot this weekend (its the wxPython PyCrust Python ZEO shell on steriods) but was failing to get post mortem debugging working.»]

online.effbot.org - Fredrik Lundh: an introduction to tkinter [«just fyi, I've updated the class reference section of the effbot.org draft edition of an introduction to tkinter. it needs a few more examples, and some copy editing, but it's almost good enough to replace the pythonware edition.»]

Mike Fletcher: PyGTA this Tuesday! [«Looks like I'm responsible for arranging PyGTA again this month (though Paul already did the hard part). So, since I haven't had any other proposals, I'm thinking of presenting OpenGL-ctypes in all it's unfinished glory. Be there @ 7pm Tuesday.»]

Runar Petursson: Website Redesign (now using TurboGears) [«Betur.net is now using TurboGears/CherryPy. ... For the first time, all the templates are Kid (I've historically used Cheetah). My thoughts on Kid vs. Cheetah for Web Applications will have to take another Blog entry. Both are very strong, just in different areas.»]

Django Weblog: Extra security for passwords [«We've added extra security to the stored passwords in Django's authentication system. Thanks to a patch from GomoX, passwords are now stored with a salt and use SHA-1 encryption instead of MD5.»]

Diary - Andrew Kuchling: Sponsors wanted for PyCon [«PyCon is now looking for sponsors to help fund the conference, ensuring that PyCon remains low-cost. Several levels of sponsorship are available to match your company's budget. Sponsoring is also a good targeted way to reach a large set of Python users. If you want to advertise something -- a product, a book, a job opening -- to the PyCon community, it costs only $200 to include your marketing material in the tote bag given to all conference attendees.»]

PyDO 2.0rc1 [«I'm pleased to announce the release of PyDO-2.0rc1. What's New: * If you pass in a module via the new "module" keyword argument of the project() method of PyDO objects and the autoschema function, the dynamically generated classes generated will be associated with that module so it can be pickled and unpickled. * several bugfixes, with corresponding tests. What it is: PyDO is Drew Csillag's ORM (Object-Relational Mapper) database access library for Python that facilitates writing a Python database access layer.»]

Jp Calderone: Axiom Powerups [«Q: When I run axiomatic -d my.axiom start, a web server starts up. How does that work?»]

Titus Brown: Delusions of grandeur [«Sparked by Ian Bicking's simple implementation of the twill language in JavaScript, as well as Robert Marchetti's Python-IE bridge project, PAMIE, I googled about and found a very recent article on PyXPCOM, too. It should be relatively easy to build a common API layer for JavaScript, mechanize/mechanoid/zope.testbrowser, PAMIE, and PyXPCOM that supports the twill language. Then you'd be able to have a single twill script that runs in-browser & from the command line, and also manipulates PAMIE and PyXPCOM.»]

Grig Gheorghiu: Cheesecake project update [«Micah Elliott graciously offered to host my Cheesecake project at his TracOS site, a Trac-based Wiki that hosts a collection of Open Source projects.»]

Cheese Shop: webcleaner 2.34 [«a filtering HTTP proxy»]

Ruby the Rival [«The interviews are a very interesting read, and the dialogue covers a diverse range of topics. The power of Ruby on Rails is a common theme throughout, and Tate argues that Rails is the catalyst that will push Ruby into the mainstream. What I don't understand is this: if Rails will make Ruby the next Java, why didn't Zope do that for Python?»]

2005-11-17

Zope Dispatches - Paul Everitt: Getting the enterprise out of CMS [«Digital Web Magazine recently did an interview with Tony Byrne of CMSWatch. I like articles like this, as they pull me up out of parochial viewpoints and give a nice glimpse of what's going on in the broader market. In particular, I like goring sacred cows, even if they're my own. I especially like how Tony took on the conventional wisdom about entperprise content management.»]

Zope Dispatches - Paul Everitt: Givin' Enfold the Windows-love they deserve [«Enfold is a Plone company, right? I mean, it's started by a Plone co-founder. Over the last year, Enfold has sponsored a bunch of work by Mark Hammond, of PythonWin fame, to improve Zope's story on Windows. Mark (along with others, such as Tim Peters and Christian Theune) has made a deep and sustained impact on how Zope behaves on Windows. This was an area of neglect, with few people that had the talent and interest to step up. Enfold is a Windows company and sells Plone stuff for Windows. It was in their interest to help Zope. Props to Enfold for doing so. (And props also for having a sweet looking company homepage.)»]

References for Python. [«This is a container class, suitable for use to answer the question "How do I pass a reference to a variable to a function", abusing some of the methods to get a syntax that's easier to use than more conventional containers.»]

Bob Ippolito: MochiKit 1.1 Intro Screencast [«I just put together the first MochiKit screencast! ... This screencast is an introduction to MochiKit 1.1, using the interactive interpreter example as a conduit for showing off concepts from each MochiKit module. MochiKit is a lightweight javascript library that brings in rich agile language features expected to users of Python and other such languages, with AJAX and DOM facilities for rapid web application development.»]

Jerome Laheurte: New home for PSP-Python, and some 3D news [«I got rid of the hand-made HTML page and replaced it with a DokuWiki. Hopefully people can contribute now, and it will be easier to maintain. I'm progressing in learning 3D programming. It's amazing how the lack of an actual interesting project, like the Python-PSP 3D module right now, kept me ignorant of such a wonderful field of experiments.»]

Jp Calderone: Axiom Queries [«Yesterday, I demonstrated how to write an axiomatic plugin. That was pretty cool, but to actually do anything interesting, you probably need to know how to define Axiom Items and perform queries. Without any ado, here's an Item definition for a popular kind of thing, a tag.»]

James Tauber: Relational Python: Projection [«Now that we have a basic class for relations and a method for displaying them, we'll now start to go through some relational operators, starting with PROJECT.»]

Zope Dispatches - Paul Everitt: Heading to the Plone Belgium meeting, Dec 7 [«The Plone Belgium user group is having its second meeting. I plan to attend, in conjunction with a ZEA partners meeting the subsequent 2 days. I attended the first Plone Belgium meeting and was very, very impressed. Turnout was good (around 30 people), the presentations were informative, and the folks enthusiastic. Afterwards we went out to a local cafe for another 2 hours of gabbing. Very enjoyable.»]

Groovie: How to Use Database Agnostic SQL in SQLObject [«One of the advantages to using SQLObject is that the code you write in it can easily be constructed in a way that ensures it'll work without a problem in all the databases SQLObject supports. This is a tremendous advantage that is most useful when writing web applications intended for wide-spread deployment on a variety of systems.»]

Groovie: The Wacky World of Ruby [«Ruby is a fairly interesting programming language, from the "expressive" syntax to some of the absolutely bizarre documentation. For a Python programmer, the lack of predictability and almost excessively concise syntax (when just one more line would really make things a lot clearer) can be a bit of a downer. Overall though, I'm rather enjoying my experiences with Ruby but not enough that I'd want to use it exclusively.»]

The ZIP archive alone is not able to take care of the issues while still following the Zope development patterns which have become common practice.»]

Anyway, I mention it because with the in-process WSGI testing patch, you can now browse your WSGI apps interactively without going through the Internet.»]

As DATABASE_COLUMN_NAMES_ARE_WAY_TOO_LONG_AND_UGLY I hardcoded 2-letter acronyms for some of them. Today the question came up whether this approach will scale to tables with a lot of columns. I immediately thought that 22^2 is quite enough possibilities, but then you have to take into account that acronyms have to actually sound a bit like the original, at the very least be composed of two letters of the original in ascending order.

Now hoping for the other part of my wish: could something like this be part of the official Zope 3 distribution?»]

James Tauber: Relational Python: Basic class for relations [«A relation is basically a set of dictionaries (called tuples) where each dictionary has identical keys (called attributes). While, as you'll see in the next couple of posts in this series, my display routine and the initial relational operators work on iterations over plain Python dictionaries, I found it useful to implement a relation, at least in these preliminary stages, using a different internal structure (something Date is clear in his book he has no problem with).»]

Checking and Sharing: Configuring which columns you want in your grid views [«If you have objects with a lot of fields and you don't want to clutter your grid views with all the extra information which better fits your detail view, then this feature is for you. Grid view in CatWalk comes now with a small dingy, like in mozilla grids. If you mouse over it, you get a dropdown where you can choose the columns you wish to display. This display settings are context dependent and CatWalk remembers them for you.»]

Nuxeo: Events in Zope 2.9 [«Zope 2.9 (and Zope 2.8 when using Five 1.2) introduces a big change: Zope 3 style container events. With container events, you finally have the ability to react to things happening to objects without have to subclass manage_afterAdd, manage_beforeDelete or manage_afterClone. Instead, you just have to register a subscriber for the appropriate event, for instance IObjectAddedEvent, and make it do the work. Indeed, the old methods like manage_afterAdd are now deprecated, you shouldn't use them anymore. Let's see how to migrate your products.»]

Griddle Noise: Adding Textile Support to Zope 3 [«I wanted to add Textile support to my Zope 3 'snippets' application. It was quite simple, thanks to Zope 3's concept of Source Types. Source Types are marker interfaces and text rendering views which render a plain text source type into HTML. The sources that are registered with the system are kept track of in a Zope Vocabulary which could be used to give users input options - plain text? structured text? reStructuredText? In a component architecture, this is just the type of thing one would want to be able to plug into and extend. Here's how I added PyTextile support into my application.»]

Since these dependencies are mostly Zope 3 packages (interface and schema) it seems natural to use Zope Corps tool for this: zpkg. Unfortunately zpkg is a complex tool with cryptic documentation. I have made packages with zpkg before, and it was hard. This time around, it was equally hard, because I had forgotten everything. I'm sorry to say this, but when it's hard to do something, and hard to remember how you did it, this is a sign of a bad design.»]

Kwalitee is an empiric measure of how good a specific body of code is. It defines quality indicators and measures the code along them. It is currently used by the CPANTS Testing Service to evaluate the 'goodness' of CPAN packages. ... I think it would be worth having a similar quality indicator for Python modules. Since the Python CPAN equivalent is the PyPI hosted at the Cheese Shop, it stands to reason that the quality indicator of a PyPI package should be called the Cheesecake index, and I hereby declare that I'm starting the Cheesecake project.»]

[«As a (mostly ex-) Java programmer myself who prefers Python to Ruby, I'm puzzled by what seems like a rush of Java programmers to embrace Ruby as though it were the only dynamic language on the planet.

But Ruby really doesn't seem like a good philosophical match with Java to me.»]

Dirt Simple: RuleDispatch Mojo Kicks Monkeypatching's Ass [«It all started a couple days ago, when Ian Bicking posted about his attempt at using generic functions for a simple JSON-ification task. Then, Rene Dudfield posted comments to the effect that generic functions were a poor fit for the task, and slower to boot. He included a benchmark that was supposed to show that generic functions were 30 times slower than a hand-optimized version of the same operation, although the numbers he posted actually showed only a 23.4 times slowdown. Well, I didn't think the benchmark was a very good one, but what the heck. I tried it out for myself, made a couple of minor tweaks, and spent 30 minutes or so writing a C version of one part of RuleDispatch that I'd been meaning to get around to anyway, and got the benchmark down to only a 1.37 times slowdown - a mere 37% slower than the hand-tuned version. But since it's still not fair to compare a function you're supposed to extend by adding new methods, with a hand-tuned version that has all the methods it will ever have, I devised a slightly fairer benchmark.»]

I wanted to use Erlang with the Berekeley XML database as well as with the Clips rules engine. After a little consideration of my options for integration, for my purposes the easy answer was Python. Running SWIG for Python on Erlang's C-based erl_interface creates the glue that gets me into Python from Erlang (with all the desired Erlang node management capabilities). From there Python already has Berkeley XML DB integration and the PyClips interface to Clips. Plus I can send Python code from Erlang over the distributed process connection and have it executed dynamically in those Python "agents". On the front end, Erlang sends JavaScript, XML, JSON, and CSS to the browser. These combinations make Sed, Awk, and various shells look downright homogenous. Bizarre combinations gathered from the bazaar. »]

Sidnei da Silva: Zope.org: Permanent Failure? [«Rumor has it that some brave folks are trying to come up with a zope3.org website, so that Zope 3 related information is found separate from the current zope.org website. I have lost track of how many different attempts have happened to restore sanity at the zope.org website.»]

Sidnei da Silva: memcached Cache Manager for Zope 2 [«Made some good progress on my memcached Cache Manager for Zope 2. ... While staring at the code for the memcached python wrapper, I wondered if there was anything that could be done to make it faster, but sadly anything that I tried just made it slower.»]

Nuxeo: "Some Zope 3 Quick Starts and Resources" [«Jeff Shell has just posted a reminder for several introductory documents and tutorials about Zope 3. Nice thing about it is that he even mentions z3lab.org, a project dear to us at Nuxeo: This site has blogs, documentation, proposals, movies, prototypes, and more, for building a high class content management platform on top of the Zope 3 framework. There is a lot of information and ideas floating around here, and the animations are very impressive.»]

Ian Maurer: Django Unit Testing [«Looking through the unit tests for the Django project, I have been able to extract a relatively simple way of creating tests for my django models that do not effect production data or need to be cleaned up after each run.»]

James Tauber: Demokritos and Leonardo [«What is Demokritos? Demokritos is an open source Atom Store I'm writing in Python. What is the relationship between Demokritos and Leonardo? The focus of Demokritos is implementing the Atom specifications. The focus of Leonardo is implementing a practical CMS for personal websites. Although the two will likely merge at some point, I think doing so at this stage would slow down things too much.»]

The Occasional Occurrence: filterized [«I converted part of MultiAuth to a filter this evening. It is now at version 0.7. It still has the metaclass and decorators for setting roles, but the actual authentiation and access control happens in the filter.»]
