Strange things running on my Mac

My iMac screen is dark and isn’t lighting up like I expect it to when I tap the keyboard. I can, however, SSH into it and see what it’s doing when not responding to me.

I found GoogleSoftwareUpdateAgent running, this FAQ item vaguely tells me it’s part of Chrome, and that if I try to uninstall it without also uninstalling Chrome it will simply “be reinstalled after a few hours.”

Two instances of PTPCamera are running. This may be related to Picture Transfer Protocol used in some cameras and has caused more than a few people to ask why it’s running.

com.apple.iCloudHelper is using a lot of CPU (100% of one of the cores). Googling for it reveals other people inspecting their systems while the screen refuses to awaken. I’m guessing it’s related to, um, iCloud and syncing, but the interwebs don’t say much more about it and killing it didn’t fix the problem.

Saving Backup Space With Time Machine and iPhoto

Three things that, when mixed, can consume a surprising amount of disk space: Backup automatically with Time Machine Use iPhoto and take a lot of photos Sync photos to one or more iOS devices like iPhones and iPads I do all three, and on top of that I have three current computers backing up to […] » about 500 words

The LGPLlicensed QuickTime plugin installs easily on Mac OS X 10.5 and does what it promises. FLV videos (such as those you’d sneakily download from YouTube) open just like any other QuickTime vid, and you can easily export them to other types.

Solaris’ CacheFS Could Be The Space Ship I’ve Been Looking For

Joerg Moellenkamp‘s post explaining CacheFS has me excited: Long ago, admins didn’t want to manage dozens of operating system installations. Instead of this they wanted to store all this data on a central fileserver (you know, the network is the computer). Thus netbooting Solaris and SunOS was invented. But there was a problem: All the […] » about 400 words

Apache, MySQL, and PHP on MacOS X

p0ps Harlow tweeted something about trying to get an AMP environment running on his Mac. Conversation followed, and eventually I sent along an email that look sorta like this: If you’re running 10.4 (I doubt it, but it’s worth mentioning because I’m most familiar with it), here’s how I’ve setup dozens of machines for web […] » about 300 words

Screencasting On Mac

I’m as annoyed as the next guy about how hard it is to find a decent screencast app for Mac. The forthcoming Mac OS 10.5’s new iChat Theater (and the built-in screen sharing/control features) should create some new opportunities for developers, but right now it’s hard to know what works or is worth trying.

Further, I narrowed the field with the following requirement: I need an app that records to QuickTime-compatible files, not Flash. Here’s what I’ve found so far:

Extra: this how-to pointed out OmniDazzle and Mouseposé as tools to help draw users’ focus during both live or recorded demos.
