In the current HailDB we have a couple of new API calls that you may like:

• ib_status_get_all()
  Is very similar to ib_cfg_get_all(). This allows the library to add new status variables without applications having to know about them – because we return a list of what there are. For Drizzle, this means that the DATA_DICTIONARY.HAILDB_STATUS table will automatically have any new status variables we add to HailDB without a single extra line of code having to be written.
• ib_set_panic_handler()
  Having a shared library call exit() is generally considered impolite. Previously, if HailDB hit corruption (or some other nasty conditions), it could call exit() and you’d never get a chance to display a sensible error message to your user (especially bad in a GUI app where the printed to console error message would be unseen). This call allows an …

As anybody who has ever implemented a Storage Engine for MySQL will know, a bunch of the DDL calls got passed a parameter named “path”. This was a filesystem path. Depending on what platform you were running, it may contain / or \ (and no, it’s not consistent on each platform). Add to that the difference if you were creating temporary tables (table name of #sql_somethingsomething) and the difference if you were one of the two (built in) engines that were able to be used for creating internal temporary tables (temp tables that are created during query execution that do not belong in a schema). Well… you had a bit of a mess.

My earlier attempts involved splitting everything up into two strings: schema name and table name. This ended badly. The final architecture we decided on was to have an object passed around that would deal with various transformations (from what the user entered to …

I need help with this. I had a dream… Well, not so much as a dream, maybe a “It’d be cool to…”

I thought it’d be nice to discover new photos on flickr using your favorite photos and the people who also favorited those photos, and the favorite photos of those who also favorited my pictures. Still with me?

It’s actually a quite simple code (about 500 lines, check it on github: discovr), but it’s terribly slow. Some possible reasons:

• Way too much data. I’ve found people with around more than 18000 favorites, and there are photos with more than 2k fans. After limiting to 50 last …

I was trying to use the PHP calendar API and immediately received this error message, “Fatal error: Call to undefined function cal_days_in_month()”. This error message means PHP was not compiled with the calendar extension.

Solution

The only solution to this error message and other similar error messages relating to the PHP calendar API requires PHP to be compiled with the calendar extension by adding “–enable-calendar” to the “configure command” as stated in the PHP documentation on the Calendar functions page.

How to Tell if the Calendar Extension is Installed

You can verify weather or not the PHP Calendar extension was compiled at install by using the phpinfo() function. When viewing the output of phpinfo() look under “Configure Command” just below “Build Date” and if you do not see “–enable-calendar” present then all PHP …

Xing is Europe's leading Business Network with more than 2 million members. Recently, Xing announced that they would come up with an API later this year to get access to the network. As far as I know, Xing was developed by ePublica using Perl and MySQL.

Having an API is essential in these mashup days. I was invited to the private alpha test and implemented a reference implementation of an API client via PHP5 which behaves like SOAPClient (but uses ReST as the transport mechanism) and overloads the methods that are available.

Here's an example of how to call it currently (API is …
