One hidden benefit to the retina display, that I haven’t seen posted anywhere, is that I can now view the screen using polarized sunglasses at any angle. This was not possible on the 3G or the 3GS. Give it a go, if you have polarized lenses…

I’ll see if I can figure out a way to post images.

Here you go 960×640:

Recently, I began work on an iPhone app and during testing I came across this error:

“The version of iPhone OS on “Gustavo Tandeciarz’s iPhone” does not match any of the versions of iPhone OS supported for development with this copy of Xcode…”

I have the latest version (3.0.1) on my iPhone, which is apparently not supported, yet by Xcode so until then, I need a work around.

Searching Google, I found this little gem:

Open Terminal and run the following:

ln -s /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0\ \(7A341\)
/Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0.1

Restart Xcode and try again. This worked perfectly on both of my Macs.

If you have a telnet server already configured (or an SSH server as is my case) but you forgot to, or need to, enable remote desktop to remotely control that computer, you can do this via the terminal.
Just connect to your console session (SSH / Telnet) and run this command:

reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v
 fDenyTSConnections /t REG_DWORD /d 0 /f

This will make Terminal Services on the remote computer allow for incoming connections. Then, for Windows 7, type in:

net start "Remote Desktop Services"

This will start the listener service on the computer. You should now be able to access the computer using the administrators account (granted, you must have admin access to the ssh or telnet terminal to do any of this).

So I was looking around at options to create a key combo to lock the screen on OS X Leopard. I came across several different options and none of them were really want I wanted. Some required running an apple script to start a screen saver, others require the key chain access application or having an icon on you menu bar or dock. All I wanted was a simple key combo to lock the screen. It’s as easy as 1-2-3…4-5-6-7-8.  This is how you do it:

1. Get Quicksilver if you dont already have it.  So many good things come from this app that it’s worth it if not for this, then for it’s pure awesomeness.
2. Enable fast user switching (System Preferences>Accounts>Login Options-last check box)
3. Go into Quicksilver Preferences (default is option+space>command+,) and make sure you have the Extra Scripts and User Accounts Module enabled under plugins.
4. Open the Quicksilver interface (option+space) and select “Fast Logout”, press ‘Tab’ then ‘right arrow’ to open up the command selections and select ‘Run: run a shell script’ and press enter.  This should bring you to the user login window.
5. If that worked, go back into Quicksilver Preferences (option+space>command+,) and select ‘Triggers’.
6. Add a new trigger by pressing the ‘+’ symbol at the bottom. Select ‘Add new hotkey’.  You should now see the default as the last command you picked (Fast Logout and ‘Run’).
7. Click Save
8. Now click on the ‘Trigger’ (it should say ‘none’) and select the hot key you wish to use.  I chose to use ‘command+option+L’ as command+L has other functions.

That’s it.  You can now lock your Mac to your heart’s content with a simple keystroke.

Well, it’s true. You can jailbreak (hack) your iPhone by navigating Safari on the phone to http://jailbreakme.com/. I successfully did this but let me throw out a few warnings and some tips.

First, a warning: After hacking my phone, I get periodic application crashes. In example, the iPod app crashes every so often. Not while playing music, but just after initial startup when it displays all my playlists. It takes about a second or two and if I click on a play list, the crash doesn’t happen. This also isn’t a “hard crash” per say. The app just closes. Safari was doing the same thing when browsing certain community websites. As annoying as this was, I was more concerned about the permanence of the situation. It seems that a soft reset solved the problem. If it happens again, I’ll post something and let you know if the reset continues to be a work around.

[Edit: The cause of the crashes is summerboard.  Uninstalling summerboard solved this problem]

Ok, now for a couple of tips/instructions. Read the rest of this entry »
