Planet Zope blog

Wordpress.com feeds got a rather ugly feature (not available from the webview) recently: they add a load of links and images to the end of each items content.

Currently its 8 images, only one is of limited use, showing the current number of comments to the post. The other images are transparent.

One can only speculate on their purpose by reading the URLs. They are called ‘categories’, ‘tags’, ‘delicious’, ’stumble’, ‘digg’ and ‘reddit’.

The last image points to ’stats.wordpress.com’, likely a counter for tracking feedreaders etc.

Overall, these images load rather slow, taking up to 8 secs compared to 0,3 secs of an average icon download. That’s the main reason why i’ve decided to remove them from the aggregated planet posts.

In case you are curious, here is the regex to clean out the html source:

re.compile('<[img |a ]+.*src="http://[feeds|stats]+.wordpress.com/.*?>(</a>)*')

I’ve added a few blogspot feeds to planetzope.org recently and realized, that blogspot feeds completely dropped the item summary and instead provide item content only.

I’ve changed the aggregator accordingly - now rss, rdf and atom content information is included with the feeditems. A fallback to description/summary is still provided.

A lot of postings about the new Repoze development/deployment environment were made during the last week, making Repoze the hot-spot on planetzope.org (besides the recently released Plone3) and as such got added to the planetzope feeds-filter permanently.

About ‘Repoze’: the website has it like ‘Plumbing Zope into the WSGI Pipeline‘, that is enabling production-grade deployments of Zope and Plone into a WSGI environment and allowing other Python WSGI applications to use Zope technologies as middleware.

Publicly announced last week - the release numbers are in the 0.2.x range - it looks stable. As a big plus they are eating their own dogfood by running the website, a pyblosxom blog, a roundup tracker, a mailman mailinglist and a plone3 demo website from Repoze, all themed by deliverance WSGI filter.

With recent plone package uploads cluttering the python package index i decided to temporary remove the cheeseshop rss feed from planet zope - until i find a rule to handle this sort of news in a better way.

Thank you for listening.

Switched ISP … sorry for the downtime - planetzope.org is visible again.

So that’s been a great year of Zope News.
After 12 months and 22 issues the service is now visited 500+ times a day from 2000+ different hosts a month. High time to discontinue the newsletter in the current format.

Thank you for your interest and stay tuned for something completely different in 2007.

‘I would actually bet on Jim´s “door #3″ (Zope2 reabsorbing Zope3) as a more likely outcome.’ - Tres Seaver*

This is a good prediction of what will be - once it is

Until then some people will go on complaining on the current state of Zope, adding to the Zope2 vs. Zope3 FUD, demanding better docs, better feedback, better manners in mailing list discussion, even a Zope fork (guys, what a waste of time) — but, these people won’t even try to give back, write docs, answer other peoples questions in mailing lists, support the community, …

Looks like it has to get worse - before it gets better again.

Anyway, here are some news from the feeds:

Big news on Philipp von Weitershausen’s Zope3 book: 2nd edition expected next month!

Baiju Muthukadan starts the ‘Eggification of Zope Packages‘: ‘Many zope.* packages are already eggified before this proposal. There are some packages remaining. This proposal is to track eggification of packages under zope namespace which are distributed with Zope 3.’ (Zope 3 wiki)

Martijn Faassen writes about ‘Grok: or what I did on my holiday‘. Grok is a very recent project, aimed at using Zope3 without ZCML. So what does Grok-based Zope 3 code look like? See yourself…

You might have noticed that I’ve omitted the last posting and combined 4 weeks into one issue. Its getting harder to find news atm, maybe you should start volunteering the newsletter now ? Check here on how to help… - d2m

Long-awaited zope.org redesign

Zope.org moves all zope-dev wikis to a new location/server at wiki.zope.org. Simon Michael of ZWiki fame dedicates quite a few hours to make that possible - thank you very much.

Zope 3 wiki moves there too and gets a great new layout thanks to Kevin Teague, based on the skin Tom Von Lahndorff created for the new Zope Foundation website. ZopeWiki.org is also available now from the new domain as wiki.zope.org/zope2.

Philipp von Weitershausen proposes to feature-freeze the Products.Five package and basically keep making it work (shrink it) for future Zope versions. Read the thread at [z3-five] RFC: The future of Products.Five.

Ian Bicking - working on OpenPlans (based on zope/plone) - looks into zope3 too. In his Zope 3 Critique he joins the latest developer discussion with some nice observations, like on zope3 adaption…

“If it quacks like a duck it’s probably a duck. Lots of uses of adaptation don’t quack; I don’t know what they all are, but they aren’t ducks.”

Worth reading anyway.
