Pierre-Alain Joye's Blog: cache added to htscanner
690629
Pierre-Alain Joye has an update on one of the PECL packages he maintains, htscanner, on his blog today:   htscanner 0.6.0 has been released. It caches the ini settings instead of looking for htaccess files in the current directory and its parents. The performance impact is yet minimal.   A new ini setting was also added, htscanner.default_ttl, to give the lifetime of the cache. You can get this latest version of htscanner from its PECL homepage.

Mike Wallner has thrown together some stats for the latest edition of the pecl/http package to test its response performance.   The results surprised me, because it clearly shows that the performance drop for starting the PHP engine and doing the neccessary negotiation to provide caching is not that bad.   There's a chart of the results as well as a full PDF with all of the stats the graph maps out. He includes the legend to make the graph easier to understand.

Trade Me has purchased a RAM SAN array from Texas Memory Systems, a storage system for serving thousands of pictures of items for sale on its site. Right now, the site uses traditional disk storage for the task, but it is encountering I/O bottlenecks.

With the release of HIT Lab NZ's OSGART (OpenSceneGraph + ARToolKit) framework imminent, I'm pleased to announce a release of the GPL-licensed ARToolKit v2.   Download ARToolKit 2.72 at http://sourceforge.net/project/showfiles.php?group_id=116280  ARToolKit 2.72 contains a number of improvements over previous releases, with several of these focussed on the video capture libraries. Wayne Piekarski and Hartmut Seichter have substantially updated the Linux video input and added Pointgrey and Gstreamer video capture.  Those of you trying to integrate ARToolKit's coordinate system with existing OpenGL drawing will be pleased to see versions of the OpenGL projection and modelview matrix creation functions which now return right-hand coordinate systems.  Integration with OpenSceneGraph is the focus of our current and future work in the area of advanced graphics capabilities atop ARToolKit. However, this release also updates libARvrml so that it binds correctly to the recently updated OpenVRML 0.16.1.  There are a number of smaller improvements, bug fixes and reference documentation updates included. Please download the release and have a look at the readme and changelog.  We have also added more explicit direction on ARToolKit licensing to the Readme. Please be aware that the GPL-licensed ARToolKit cannot be used in a closed-source product. Closed-source licenses to ARToolKit Professional are available from ARToolworks in return for financial support of ARToolKit development efforts.  If you find bugs in this GPL release, please post in ARToolKit's bug tracker on SourceForge at http://sourceforge.net/tracker/?group_id=116280&atid=674305. This is the preferred forum for bug reports. Patch submissions are also welcomed.  And yes, bugs fixes and other improvements are available between official ARToolKit releases by checking out the source from Sourceforge ARToolKit CVS repository using anonymous CVS. A simple tutorial on how to get the ARToolKit source using a CVS GUI tool is at http://sourceforge.net/docman/display_doc.php?docid=25731&group_id=116280.  Thanks to all the contributors to this release.  Philip Lamb HIT Lab NZ

Padraic Brady has posted today about a subclass of the Zend_Loader package (in the Zend Framework) he had written up to handle Dependency Injections - it was submitted but ended up being replaced with a Zend_Di component instead.   I realised someone had proposed a novel new component called Zend_Di, and that small change was since accepted by Federico into his DI buster. This is a quick overview with very simple use cases - read the full proposal for even more gory details about your object innards using DI.   He talks about what DI (dependency injection) is and what it can be used for and includes a simple example set around a controller in the framework that uses the Zend_Di component to make a "mock Zend_Mail" that can be used in testing too. Examples of these sorts of tests (with PHPSpec) are included too.

We have some big news today for FlickrFan users, a major new source of high-def photography for the networked living room. They come from Agence France-Presse, one of the world's great news organizations, and a fantastic source of high-resolution news photography. I met with Agence France-Presse when I was in Paris in December, introduced them to FlickrFan and explained what we were doing with the Associated Press. They got excited, it took a little while to work out the technical details, but now we're ready to go. The updates are all out, here's the howto for FlickrFan users. Change #30: Agence France-Presse photos in FlickrFan. There were unique challenges in this project because their flow is huge. Yesterday we got over 3000 new photos. Because there are so many, I asked my friend Matt Mullenweg, if his company Automattic could help us out with server space and bandwidth, and he said yes. The AFP pictures are hosted on wordpress.com. Many thanks to Matt and his company for helping us out. To the extent we're bootstrapping a new use of the net, which I hope is what we're doing, Matt's company has made the kind of contribution we'd like to see more companies make. Usually the companies are happy to make the money, but not willing to help out with the bootstrap, which often costs money. Matt has always been a great guy and a visionary. I thank him and hope that FlickrFan users find an appropriate way to thank him too. And also, please consider the generosity of Associated Press and Agence France-Presse. We all hope that there's a market here, a way to monetize the flow of high-resolution photography to enrich and inform. Other content companies have been reluctant to take a chance on the Internet, we saw that in the early days of RSS and podcasting. I feel that these two media companies are playing the same pioneering role that the New York Times played with RSS 2.0 and NPR played in podcasting. Associated Press and Agence France-Presse deserve our respect and admiration for steping out, for going first, this is how new Internet activities get going. This is what we call market leadership, the real kind. Bravo!! And this couldn't come at a better time, with tomorrow being Super Tuesday here in the USA. Think of all the great photographs we're going to get in the next few days! Kevin Tofel helped test the feed over the weekend.

There's a tutorial over on mpwebwizard.com that's been updated and talks about using a mirror to handle hits from a popular website (like digg or slashdot).   caching services such as coral content distribution network provide an alternative for when your site goes down, but why wait until it gets to that stage? why not just send all your hits from high-end websites to the coral cache version? well, there isn't a good reason not to, so i'll show you how to do it automatically.   He provides the simple script that looks for certain sites in the "HTTP_REFERER" value of incoming calls and pushes them off to the cached location with a header() redirect. The whole thing is only 12 lines, not counting the $sites array.

Perl script that automatically searches for new episodes of your favorite TV shows and downloads the corresponding NZB files from various free sources on the internet.   This release is mostly just to update the .shows file and the README.  I was sleepy, and I stupidly said that you do not have to have the  element in your shows file.  Turns out I'm just an idiot, and you do.  I have updated the .shows file to include the proper template for most shows, which is %name%.S%season%E%episode%  Sorry about that!  I also started a code optimization run which will hopefully over time make things run faster and more efficiently.  I just picked off the low hanging fruit on this release, because I wanted to get the updated README out before too many people had problems.

In a follow-up to a previous blog post, Alexey Zakhlestin shares a few more thoughts on the project and the proper object hierarchy's going for.   actually, I changed it completely 3 times already in my thoughts. I finally "see the light"(tm) and will implement it on a weekend. I think about converting SCGI-part to a simple "driver" and move all http-related stuff to a separate driver-agnostic set of classes. This way, I would be able to implement FastCGI as anther driver without altering applications. If you have any better ideas - let me know.   He also includes a link to another sample application that uses the functionality to create a pie chart (including some benchmarks) with the help of the eZ components framework.

Simple tool for mass-renaming of files, download of episode lists from TV.com, TVRage or AniDB, analyzing a folder (number of files and total size for each file type), creating and checking of SFV files all in a single executable jar.   What's new in FileBot 1.6: * Episode list searches work much better now (AniDB works again) * Much better handling of lots of files when creating/check sfv files * DnD improvements * Lots of bugfixes

Gennady Feldman, in light of some of the recent talk about enhancing the performance of your PHP applications, has written up this new post comparing two of the more favored software packages - APC and Eaccelerator.   Some websites use other technologies like Java and face the exact same problems. There are different variables involved here and the most common one is database. So I thought i would post a couple of articles related to performance and tuning.   This this post of the series focuses on the first of the two - APC - and talks about places it's used and includes some general performance recommendations. These include "Don't try to throw everything at your poor database" and the importance of XDebug.
