Working on a Drupal site that's already half-way started, I noticed that after installing the admin_menu module many links I expected were missing, such as the refresh cache links and several content types under the Content Types menu.

First, I tried clearing out all caches manually via the Performance page.

Next, I tried truncating all cache tables in case cache_menu or another table was corrupted.

Still no go, so I tried disabling, uninstalling, and reinstalling the admin_menu module which should rebuild the admin_menu links in the menu router.

In the end it turned out to be a Wampserver problem as it (as well as Xampp) use PHP 5.3, which Drupal has a lot of problems with. PHP 5.3 has a change from earlier versions in that function declarations like:

function admin_menu_admin_menu(&$deleted)

no longer work. Normally, you'd see that in your error messages.

The solution is to remove the & before $deleted on line 107 in admin_menu.inc in the admin_menu module. This will also make the related PHP warnings go away.

Running 5.2 and 5.3 on one computer using XAMPP (on OSX) is easy by following these instructions: https://gist.github.com/1012774

Location-based services, FourSquare and its clones are everywhere. China (where I guess 4sq is blocked anyways) has already produced a number of 4sq clones. I know of at least two 4sq clones or location-based services operating in Vietnam (shout out to friends at go100). And earlier this year Koprol, an Indonesian FourSquare-ish LBS was acquired by Yahoo.

But the number of stores and restaurants offering actual benefits to users repeatedly checking in... is less than the number of competing websites where you can check-in to them.

Tired of Foursquare, Inc. spamming your Twitter? Could you care less that someone goes somewhere so often they become its "mayor"?

Take back your Twitter feed with h8sq, a plugin/extension for the Google Chrome
browser which will:

Remove annoying tweets like "I'm at McDonalds. http://4sq.com/stupid
Remove annoying tweets like "I just became the mayor of McDonalds! http://4sq.com/stupid"
Remove annoying tweets like "I just unlocked the Douche badge! http://4sq.com/stupid"
Remove annoying tweets like "I just ousted So-and-so ..." (new)

It will leave alone tweets that have been personalized or merely mention 4sq.

If you run chrome just install the attached script, which should also work with Opera and with Firefox via Greasemonkey.

Install h8sq for Chrome (and maybe other browsers)

UPDATE: Now works on Twitter.com, Seesmic.com, and Hootsuite.com!

So there's been a lot of chatter in the Saigon twitter community lately about the average income of Ho Chi Minh City and whether $600/month can get you a decent middle-class lifestyle here.

This is what it costs to live in Saigon, Vietnam's (and all of French Indochina's) largest, busiest city and commercial center:
