Tech tips & other words
Looking to speed up your SocialEngine, Drupal, or other PHP/MySQL web site? The combination of APC and Memcache can really speed up sites based on these platforms. If you’re an admin of a server running Mac OS X Server (10.6), here’s how to install APC and memcache on Mac OS X server:
Download and install MacPorts from http://macports.org.
I wanted to test the new MySQL 5.5.6 on Mac OS X 10.6.4. It’s got problems, so I chose to downgrade to the current stable release of MySQL (5.1.51-community). I ran into bad news though, as the installer refused to progress, complaining that a newer version was already installed.
Here’s how I got rid of the old one:
Changing domains around on your web server can leave you with a local DNS cache that doesn’t match your domain’s new settings. Flush your DNS cache on Mac OS X 10.5 by issuing the following command:
dscacheutil -flushcacheEdit 5/19/2014: OS X Mavericks has a slightly different method for clearing the DNS cache.
Sure, Firefox has a great plug-in architecture that has created a rich ecosystem of third-party add-ons, but Safari’s got a halfway decent development debugging environment as well. Here’s how to enable it: Continue reading
So, you need GD for your killer PHP web app, and you’re running Mac OS X 10.5? A quick look shows that GD doesn’t ship with Leopard. No worries. It’s pretty simple to install.
Locked out of a Mac because Remote Desktop has suddenly taken a crap on you? Want to remotely enable Screen Sharing (Apple’s fancy name for VNC)? Well, as long as you have SSH active, you can enable Screen Sharing on Mac OS X 10.5 by following these easy instructions.
Apple’s new Mac OS X 10.5 (Leopard) changes how web sharing is set up. Thankfully, they’ve moved us all to Apache 2 codebase (a good thingâ?¢). But in doing so, they’ve disabled the ability to serve web pages contained in your home Site directory.
If you turn on Web Sharing from the System Preferences panel, it works for the main computer (http://localhost) but not for user accounts (http://localhost/~username/). Most perplexing is that Apple’s graphical interface confirms that web sharing is turned on for your personal account, but it doesn’t work. This is *very* un-Apple.
Even if you turn on web sharing from the System Preferences panel, you’ll still receive the dreaded 403 Forbidden. You don't have permission to access /~username/ on this server.
Thankfully, it’s a simple oversight on Apple’s part. Your options are two-fold. You can either set it up to activate the Sites directory in all your user accounts, or just for individual ones. I’ll cover both. Continue reading
Since the release of Apple’s 10.4.10 update, users (including me) have been complaining to Apple that their third-party USB web cams have lost audio capabilities. Although a bug report was issued and acknowledged (ID #5285354) by Apple, no fix has been forthcoming. In fact, Apple has stranded a large number of users in a void where iChat AV no longer has audio and video chat functionality. Continue reading
I recently needed to access the GUI of my Mac at work from home. Alas, Apple Remote Desktop Sharing was turned off.
Here’s how to turn on Remote Desktop Sharing from the command line. This assumes you have Remote Login (SSH) turned on in system preferences. If not, you’re hosed. Continue reading
Reader Charles asked a great question after reading my post about hiding a mounted disk volume on the desktop. He asked, in a nutshell, how to cause Mac OS X to not automatically mount a volume. Basically, Charles wants to leave his bootcamp volume unmounted when in Mac OS X. As it sits, Mac OS X automatically mounts all non-removable drives at startup. Continue reading
