Odin Assemble meet Media Temple Grid-Server

2006-11-08T17:57:00.000-08:00

If the idea of the new Media Temple Grid-Server tickled your fancy you can rest assured you are not alone. We were so intrigued by the idea that we wanted to test Odin Assemble on the platform immediately. The results are in folks and I'm happy to share Odin Assemble is 100% compatible with the new Grid-Server product.

Migrating to PHP5

2006-10-19T17:48:00.000-07:00

Here is some interesting reading from IBM to help you with your PHP4 to PHP5 migrations. Odin Assemble is still PHP4 but the porting has already begun.

Interesting PHP Reading

2006-10-04T09:17:00.000-07:00

While I'm a bit behind in mentioning this (better late then never) I wish to share an interesing bit of PHP reading from IBM. At Odin we love PHP and while a lot of attention is being directed towards Ruby we feel motivated to share anything (and everything) PHP oriented.

Box.net Flucations

We've been expierencing connectivity issues with Box.net as of late. If this continues we may have to remove our box.net backup support.

The Amazon S3 system at just 15 cents per gigabyte is looking like an interesting alternative thanks to some great work by Christopher Shephard.

I recently noticed an interesting post from the TRYNT guys. According to this entry they've been on the recieving end of a lot of traffic thanks to popurls.com (and from what we can see Waxy.org as well).

At the time of this entry TRYNT has an Alexa ranking of 16,207 (it is very peaky though) and Odin Assemble is handling the load in stride.

PEAR Cache_Lite vs the Alternative PHP Cache (APC) Wrap-up

2006-08-30T15:03:00.000-07:00

While it does appear that the Alternative PHP Cache (APC) is faster then PEAR Cache_Lite, it is only marginally faster. After comparing a total of 3,000 unique cache write and cache reads APC was only 0.0003 seconds faster.

Since APC is not bundled with PHP and it generally requires additional installation and configuration steps it doesn't seem to be well matched for Odin Assemble.

We'd love to hear any insights you may have from personal expierence with APC. Let us know your thoughts!

PEAR Cache_Lite vs the Alternative PHP Cache (APC)

2006-08-30T09:24:00.000-07:00

While reading through the Yahoo Developers website I stumbled upon PHP : Cache Yahoo! Web Service REST Calls. This HOWTO uses the Alternate PHP Cache (APC) as its caching mechanism while Odin Assemble on the other hand uses PEAR Cache_Lite. This motivated us to do a little bit of benchmarking. If APC proves faster then we'll integrate support :).

Encoding or Obsfucating? Historically Odin Assemble has been "encoded" using the Ioncube PHP Encoder. While this solution has fared us well in the past it comes with a price. The Ioncube PHP Encoder requires a platform specific "loader" that adds the complexity of Odin Assemble installations.

To reduce installation complexity we've decided to do away with the Ioncube encoding in the next public release. We plan to replace the Ioncube PHP Encoder with POBS.

Box.net is a nifty service. It's inexpensive (or free), can be easily mounted as a virtual drive in various operating systems and offers a useful API for developers. All those things being taken into consideration we've decided to implement a Box.net element in our (in development) backup system which provices an additional level of offsite protection.

2006-08-11T09:32:00.000-07:00

The question "Do you have any tips for maximizing the performance of Odin Assemble?" was recently asked by an OA site owner.

Here are a few suggestions:

Pre-index your website (v3.0b only) - We recommend mode 1 or complete indexing for maximum performance. Remember to specify your pre-index data file with $use_idx.
Enable "page caching" - In your config give $_page_cache_life a reasonable value (in seconds). Since "page caching" acts globally you'll be caching all your elements and template interpolations. You can set "cache exclusions" as well for pages that are less then cache friendly (like login pages) by setting a regular expression value for $_avoid_cache.
Disable page compression - While page compression can save bandwidth its at the expense of the CPU. You'll save bandwidth through compression which can adversely effect performance. You can disable compression by setting $use_compression false.
Enable If Then Modified - By enabling If Then Modified you'll reduce your overall transfer by taking advantage of browser based caching. Enable If Then Modified by setting $use_if_then true.
Disable contextual keyword generation - If you are looking to extract every last ounce of speed you may want to disable contextual keyword generation by setting $use_contextual false. Why? Because the contextual keyword generation is dependent on third party web services this feature can effect performance.

Is your website still acting sluggish? If you are making use of a database now would be a good time to check it. Are you using elements you've developed? Try profiling your elements to see if any particular element is causing slow down.

Still frustrated? Let us know and we'll see what insight we can offer :).

If you haven't made your way to TRYNT yet I encourage it greatly. The TRYNT team has used the Odin Assemble platform to launch twenty seven web services. The web services are provided free of charge and TRYNT is asking only for a bit of attribution.

For the Ning fans out there TRYNT has released two unique Ning based mash-ups: Ping Me Ning and Movie Data.

IMHO lots of cool stuff from the TRYNT camp!

Is is time for a control panel? We've made it this far without the need for more then a handy installer but with more then a few new tools and extensions a control panel maybe just what we need to keep everything organized.

Have no fear OA purists if a control panel is in the future it will be 100% optional. We feel strongly about OA sticking to it's roots.

While local backups are good, offsite backups are better. Why? Local backups are not efficient against fire, flood, theft not to mention many more disastrous situations.

Thats why we've put a lot of time and energy into developing an integrated offsite backup solution into Odin Assemble. The new OA backup system will provide redundant backup storage in multiple unique geographic locations.

2006-08-08T17:03:00.000-07:00

Since the pre-indexing system is working like a charm we've decided to expand its function. A new "roll back" function and an offsite automated backup function are currently under development.

We've rehashed the popular My Timelines tool (Big Thanks to TRYNT for the iCal API) to now support Apple iCalendar files. With the advent of many Web 2.0 calendar applications the Apple iCalendar file is popping up all over the place.

We mentioned earlier the new (optional) pre-indexing feature of Odin Assemble v3.0 and I wanted to take a second to cover this item in a bit more detail.

While Odin Assemble doesn't use the Smarty templating system I think that the point being made by Cal Henderson (of Flickr fame) in his book "Building Scalable Web Sites" about pre-compiling is an important one.

"Similar to the opcode compilation, repeating the same compilation process multiple time is a waste of server resources." (Chapter 8: Bottlenecks, Pg. 173)

Since OA "compiles" or "builds" each page on the fly it reasons that by "pre-compiling" as many steps as possible will serve to speed up the entire framework. Cal provides a short PHP script for the Smarty system on Pg. 173 of his book. In concept this script is very similar to the new pre-indexing script included in Odin Assemble v3.0.

2006-07-19T17:19:00.000-07:00

Are you running a website powered by Odin Assemble? Are you interesting in helping us beta test the new Odin Assemble v3.0 beta. Now featuring "even more features" :).

Does the "Powered by Odin Assemble" bit not fit into the constraints of your current project? We've been toying with the idea of offering a corporate or business licensing option that would do away with OA branding.

Licensing possibilities could include:

Corporate License
Access to a private support forum and removal of all Odin Assemble branding.
Corporate License with Installation
Installation service for OA on a compatible server of your choice. Access to a private support forum and removal of all Odin Assemble branding.
Hosted Corporate License
Web/Database/Email Hosting at Odin Hosting. Installation service for OA. Access to a private support forum and removal of all Odin Assemble branding.

SEO Hosted Corporate License
Web/Database/Email Hosting at Odin Hosting on a unique IP. Installation service for OA. Access to a private support forum and removal of all Odin Assemble branding.

We are now testing a new version of Odin Assemble, version 3.0 beta. We've added more then a few new features to the framework, highlights include:

A new (optional) pre-indexing system that can dramatically improve the performance of high traffic, element, page or template heavy websites
The introduction of "compiled templates"
An obfuscated instead of compiled PHP core

We are beta testing the 3.0 beta build at Alternate URL Ads. Additional beta test sites will be posted shortly.
