Plone 4, ZEO and tempstorage

This is reminder for myself and hopefully for other people too so that they don't have to waste several hours of valuable time looking for this simple piece of information.

If you have experience setting up Plone 3 with ZEO and tempstorage (so that your sessions won't disappear in the middle of hardcore content managing) you might have trouble setting up same kind of setup while using Plone 4.

Thanks to David Glick who enlightened  me that plone.recipe.zeoserver doesn't include whole Zope 2 in it's Python environment anymore. In this specific scenario this means that even though you have tempstorage in your eggs folder it isn't included in pythonpath when zeoserver part is being processed and this leads to below error message:

Error: could not load package tempstorage: No module named tempstorage
Package name: 'tempstorage'
File name: 'component.xml'
Package path: None
For help, use bin/zeo-server -h


Solution to this is to add this simple oneliner to your buildout.cfg zeoserver part:


[zeoserver]
...
eggs = tempstorage

Domain name registration through Google - when things go wrong.

Not too many people know, that you can register new domains through Google. This can be done when you're registering for Google Apps Standard Edition which is free and somewhat stripped version of their Google Apps Premium Edition. Latter one is tailored more to suit business needs.

With $10/year prize tag it's not cheapest option, but you'll get "private domain registration to protect against spam at no extra cost, full DNS control and domain management, automatically configured to work with Google services, email, calendar, instant messaging, web pages and more also at no extra charge".

As a comparsion GoDaddy offers .org domains at $14.99/year so it's actually not that bad offer. Google actually is just collecting the data and sending it to their partners (godaddy, enome) which does the registration. I decided to give it a try at January 11th. To my big surprise things didn't went that smoothly. It's been now one week since my order - the domain I …

Speed comparsions between Plone and Wordpress

Jon Stahl wrote recently a blogpost about Plone being three times faster than Dropal, Joomla and Wordpress. We had a small discussion about this in my workplace and as my colleague pointed out this wasn't a really that comprehensive test that you could state Plone being 3 times faster than it's competitors. This seemed a bit unfair test considering how fast this has been spread in tweet/blogosphere, so I decided to repeat the test with a bit more critical viewpoint.


What's wrong in the original test? No one would consider opinion poll with 10 answers nowhere near trustworthy - it's all the same with requests. I didn't want to put up all the cms so I just set up second best (Wordpress 2.9.1) and compared that to my Plone development site (4.0a3). As a comparsion I did the first test with same ab command Jon used and my iMac gave following results:


Wordpress: 7.13 requests / second
Plone: 17.10 requests / second


So far we have clear winner and Jons data holds up... almos…

cd under development packages nested folders without repeating yourself

To me Plone development environment means Fedora 12, terminator and vim. As I do lots of development in the shell there has been one annoying little thing which I'm tired of - cd:ing under development packages inner structure to where the actual code lives.


Doesn't seem much but if you repeat that many times a day you'll get tired of it. Of course you can always launch vim for the package root and open the file you wanted from there, but it's still extra effort.

Few weeks ago me and my colleague Jussi Talaskivi started to think that there has to be a script which takes you to your destination simply by parsing dotted name and using information from there to cd you to the correct place. After spending some time googling around we found none. Annoyed by this we decided to do this missing script by ourself.

Soon it turned out that this wasn't that easy task as it sounds - simple shell or python script where you just parse correct path from arguments wouldn't do t…
