The media management extension DAM is no longer supported in TYPO3 6.2 LTS, the functionality will be replaced by the new file abstraction layer – FAL. The challenge is to migrate the existing DAM structures to FAL without losing any data and file relations.
Caution: the following tasks must be run AFTER the migration to TYPO3 6.2 LTS (and with all DAM and related extensions uninstalled)
Upgrading an existing TYPO3 4.x installation to TYPO3 6.2 LTS can be a challenge due to massive refactoring of the core in 6.2 and especially the new file management layer (File Abstraction Layer – FAL). Besides upgrading the core system, several third-party-extensions need to be migrated or replaced by alternatives. There are some essential ones which will no longer work on 6.2. This little step-by-step guide is just a rudiment documentation of the pitfalls and workarounds in our migration process. It is NOT a complete migration guide, but addresses special issues like DAM to FAL migration in combination with tt_news, replacement of deprecated extensions like css_filelinks and tips for migration of custom extbase extensions built with TYPO3 4.x.
Rendering a DateTime Object in a fluid template based on localized PHP settings seems not too easy – for me, the easiest way to solve this problem is via custom viewhelper, which renders a given DateTime based on the PHP “strftime” function.

If you have an extbase extension and you need to call a controller action via TypoScript, things have changed from TYPO3 4.7 to 6.1. TYPO3 6 has a lot of code rewritten, depends heavily on PHP namespaces and extbase extensions from earlier versions will no longer work.
To get started with all the necessary bootstrap code for a new extension, use the extension “extension_builder” from TER.

After Upgrading my iPad 3 to iOS 6, i experienced a very slow and unstable wifi performance. This is my hardware setup:
The problem was the wifi standard mode – the router supports the standards 802.11b and 802.11g and offers a “mixed” mode, where devices will automatically choose the right standard. The mixed mode caused the problem, changing the configuration to “g-only” fixed the issues and wifi works as expected again.
If you are using the popular extension “tt_news”, you probably want the news title as page title on the single view of the news entries. Especially for SEO and sharing (Facebook, Twitter,…) it is very useful to have this information in the TITLE – tag of the page.

This posting is based on version 4.3.3 of typo3.
It is often necessary to display thumbnails with fixed width and height values for each image (e.g. some image gallery…), which is a challenge if you have images of different formats (4:3, 16:9,…).
Typo3 offers the “cropping” function, which means the original image is scaled to a given width and height – to preserve the proportions of the image, it automatically resizes the images to match the given values.

The loading time of a website gets a lot of attention these days, at least since google said, that the loading speed is a factor for the ranking position. With compression of text files (CSS, HTML, JS) you can speed up the performance easily.

The documentation of Aptana 2.0 is poor at the moment, i did not find any docs on the new PDT PHP extension. Maybe someone has the same troubles getting php debugging to work – here is how i got it finally running:

Recently, a weird problem occured in my current typo3 – project. The caching was configured properly (out of the box configuration) and all caching tables were written as they should – but with a very confusing behaviour: the whole page was generated completely new by typo3 on each page request, which caused high server load. The error was not caused by an overriden no_cache-value or one of the other usual suspects (USER_INT, config – directives). After spending days trying to find a fix for the problem, i finally found a solution:
