Installing Python, virtualenv, NumPy, SciPy, matplotlib and IPython on Lion Testing GitHub as Blogging Platform
To begin, there has been some concern that users can't perform a clean install of Mac OS X 10.7 (Lion) without quite a bit of hacking around with physical media. I'm happy to report that isn't true -- as long as you performed a standard Lion install first. The OSX installer (App Store link) automatically creates a "Recovery HD" partition on your hard drive, just in case something goes wrong. The partition contains just two things: Disk Utility and the ability to run the Lion installer. To access this recovery mode, hold Command-R while your computer is starting up. Use Disk Utility to erase your hard drive, then run the installer to re-download and load Lion. When you're done, you'll have a clean install of Lion. Download your favorite browser and you're good to go. I have to say, discovering this feature was a pleasant surprise -- hats off to Apple for thinking ahead on this one.
I don't know if I knew this. Can that recovery HD partition be burned to a CD and booted from there? Anyone?
