Default location of screen dumps

Using the Terminal, enter the following command to change the location:

defaults write com.apple.screencapture location ~/Pictures

This snippet will change the default location of saving the screenshot to the Pictures folder. You can also set this location to any folder or volume on your Mac, just substitute~/Pictures in this command to whatever you want. Once you've run this command, you'll need to restart the SystemUIServer (used to control certain interface elements in Mac OS X), by entering killall SystemUIServer in the Terminal.

Backgrounding Apps

MacRumors has heard that Apple are still thinking of allowing the user to run a small number of background apps on the phone.

This is something that I think we still need to see. The Push notification service is a good solution for apps that aren't accessing the environment around. But apps such as a tracker for following your position really do need to be on all the time, as do internet radio apps.
The main marketing thrust of the Pre is surely going to be around the multi-tasking. We all know by now, by experience or education that background apps drain the battery in no time at all, but this won't be mentioned in press blurb. If Apple want to close that angle of attack, allowing a limited form of BackApps would seem necessary.

When I first considered the problem, the solution that formulated in my head, was that apps should be written as 2 parts; the main app and a background app process that could be called on a regular interval say 5 seconds. The background process app could be restricted to no UI and a very limited API to throttle how much cpu and power it used. BackApps could be terminated if they took more than n seconds to return control.

The idea that certain locations in the dock or springboard would be for BackApps since a neat one. Trying to juggle apps with WinMobile task manager was always a nightmare on my TyTnII and they really ate the battery.

Perhaps they should make it that apps in the dock can be backgrounded, and that to cancel the process you simply slide your finger as if to pull the app off the dock, to terminate any bg processes.

Whatever their solution I do hope that some form of BG app even in a very limited form is on the cards, it would transform the device and apps.

Colour your shell prompt taken from Lifehacker


Using the tip is relatively simple—just edit the /root/.bashrc file and add in the following, preferably commenting out the existing lines that set the color, though you can simply add this line to the end of the file.

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

Once you've added this line, anytime you switch to using the root shell you will see the prompt in red with white text for the command line. Chris takes it further, with a line that turns the prompt green for regular users, which you can enable by adding the following to your ~/.bashrc file:

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\

Kraftwerk - Autobahn.

Quick Drunken Thoughts... as usual... ( on ripping my cd copy )

Its years since I listened to this album and it just took me back 30+ years instantly. That wonderment that machines could make imitate the sound of cars flying past on a road.
Cortinas were still curvey, as were escorts. We had just been to the continent for the first time, it seemed so exotic. My brothers musical tastes merged with my love of gadgets and science fiction.
I must have been about 10 or so. Getting ready for my first computer. Practicing learning how to touch type from the cover of brochure for a Sinclair Spectrum. (It worked ).

Also roughly the time of Xray Specs, Blondie, Donna Summer, Abba ( VV ), Oxygene. The world seemed so visceral and the electronics so alien but exciting. Walkmen were just coming in.

Will pipe more thoughts about this time soon. Loved it. Love the original blue ( vertigo ) sleeve
Of course, kraftwerk The Model? was used for the BBC computer program.
..

my brother and I would sit in his bed. turn off the lights and pretend we were still driving through Germany after our holiday/adventure there that year. The music seemed to fit perfectly. I think we only saw a few UK people the whole time we were abroad. How it changes.

wow, last track did it all over again. such an influence on me musically. i loved the melancholy hopefulness of the track, wistful. it always meant that i would have to go back to my room and go to bed as by now I'd be in trouble for staying up too late.

iTunes select album of current song

option click the arrow on the current song album name, opens the whole album.


iPhone 3.0 wishlist

What would I like to see in 3.0

1. Copy / Paste - like duh!
2. Background threads - ( maybe not apps )
3. Access to itunes library NSTunesPicker ?
4. Better mp3 decoding support.
5. AudioUnit registration


I don't think full back ground apps are required. I think apps could have a
-(void)didReceiveBackground notification

a bit like the one you do for closing. and you could spawn a tiny version or something. But the full app must close. That would be fine. Restricted stuff, no user interface etc
