How to Prevent Dismissing Containing View Controller when Performing a Double-Tap on a UIPopoverController’s Background under iOS8 in Objective-C

When opening up a popover from a modal view (or another popover) on an iPad running iOS 8 and double-tapping on the background of the popover, not only the popover will be dismissed but also the modal view. This behavior was non-existant in iOS 7 and seems to be a bug in iOS 8.

I’ve came across the problem that i cannot create a new virtual machine of Mac OS X Yosemite 10.10 on my new Mac Mini. The problem I experience is that there is no option on the install screen prompting me to »Install OS X Using the Recovery Partition«. The screenshot below shows this option.

Fix MacBook Bootcamp Windows XP SP3 Firewire S100 driver problem

MacBook FireWire socket with cable

I recently wanted to use a FireWire camera (a Pointgrey Firefly MV to be precise) with a white MacBook that ran with Windows XP SP3 in Bootcamp. That actually is no problem but I got into problems when I wanted to achieve higher framerates than 15 Hz. Then I realized that the only Async/Isoch mode that the MacBook offered was S100 (which as far as I know) means a downstream of 100 MBit/s. This is four times slower than the 400 MBit/s that FireWire 400 is capable of.

MBP Keyboard Assembly: Backlight illumination with FTIR

Today I have made an interesting discovery: my 2008 2.4 GHz MacBook Pro is using frustrated total internal reflection (FTIR) for the illumination of its keyboard.

The background to this discovery is that I spilled a bit of salad dressing into my keyboard (pro tip: do never try to show someone the salad you are currently eating via skype) and since then some of my keys are not working reliable anymore. To be more precise: Some keys I must push two or three times until they produce the letter. Thus, I wanted to look if I could clean the keyboard and what kind of keyboard I would need if I wanted to replace it. I used the MBP iFixit guide to achieve the disassembly (and as I have been a lucky guy also the reassembly).

Anyway, when I removed the keyboard compartment from the MBP’s body I discovered that it consisted of four parts:
