My slides from the "APC & Memcache the High Performance Duo" talk are now online and can be found here. In the slide I mentioned that memcache is available of *NIX only, which thanks to at least two attendees I know to be incorrect. It appears that there is a working (albeit old, circa 2006) memcache win32 version, which you can find here: http://jehiah.cz/projects/memcached-win32/ Once you install it, you'd need to compile memcache PHP extension on win32 and then you should be set.

The slides from my "Common Optimization Mistakes" talk are now up and can be found here.

It has been a rather crazy last two weeks at work, so I didn't get a chance to revisit the type hinting matter. Unfortunately, while initial outpouring of support for inclusion of type hinting into PHP 5.3 and 6 was substantial, it all kinda petered out once more people started voting. To be specific, there is a large amount of support for the feature in general, but very few people seem to think it should go into 5.3. I feel that 5.3 is the only release that would make this feature usable, since that is the version of PHP I could see myself using at work in a near future as well as a release other people would be using for the next few years, at least. PHP 6 is just very far a way from any sort of a release, let alone a production worthy version and at the same time there is no tentative agreement on making 5.4 in the near future. If it went to 5.3, which would be "work worthy" I could justify spending the time to maintain the patch across all branches, but with PHP 6 only, it is simply too impractical. T...

There has been a lot of comments both on this blog and the internals list. There seems to be a fairly large group of core developers who like the idea as well as surpassingly large support base on the user level too (wow, didn't think that this many people want type hinting). Unfortunately, there have also been, as is typically on the internals list a few people complaining for the sake of complaining. Their arguments have ranged from type hinting is against PHP's loosely typed nature and people will mis-use it and make PHP into something that it is not, to I don't need or will use it, so no one should get it. That said these people are in the minority, albeit a rather vocal one, so progress is being made. There have also been a number of really good suggestions by folks who have reviewed the patch (big thanks guys) and their improvements have been incorporated into the version 2 of the patch. Here is the quick changelog. 1) Added support for "object" type hint 2) Modified the patch not to break binary co...
