One of the things I love about OS X is the bundled Grab utility.
All OS's allow you to capture screen shots, but most only allow you to capture the entire screen, OS X's Grab allow's to capture either the whole screen, a whole window, or allows you to drag a box over the area you wish to capture. It's something I've come to use everyday.
There is one niggling issue though, by default Grab insists on saving the captured images as tiff files. And there seems to be no easy way to change. After a bit of googling though I found it can be changed using the defaults utility in the terminal.
This is why I love Valve, unrivaled brilliance...
I recently ran into an issue on my work Mac desktop where the spotlight index seemed to become broken in some way. When I went to search for a particular application it was often not finding it or recommending a very old or classic build of the app. This is obviously a big frustration, as Spotlight is a big selling point of OS X and one I rely on in my day to day use of the machine.
To fix this I found a quick and easy way to rebuild the index without having to delve into the terminal, and here's how:
- First, you are going to want to open System Preferences.
Compliling your own Kernel can be very frustrating if you don't know what you are doing. I have done it numerous times yet I always manage to forget a step or two along the way, so I've created this quick and dirty guide to remind myself (and hopefully remind/enlighten you) as to the process.
There a few things that you will need before you can begin the process of compiling and installing a new kernel. You will need to ensure that you have the right compilers and sources installed in order to compile.
Installing the compiler
When people refer to Linux, they are often refering to the entire operating system, ie user and system applications and the user interfaces to use them, such as Gnome. In reality Linux refers to the Kernel at the heart of it all, the one originally developed by Linus Torvalds. As my project involves working with the Kernel and making changes (hacking) to it I decent understanding of what it does is essential. In this post I outline (very briefly and crudely) the main functions of the Kernel.
1. Edit: /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/SDKSettings.plist and change CODE_SIGNING_REQUIRED from YES to NO.
(Obviously you should change iPhoneOS3.0.sdk to the correct folder for whatever SDK you are planning to use.
2. Run this script:
#!/bin/bash cd /Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Plug-ins/iPhoneOS\ Build\ System\ Support.xcplugin/Contents/MacOS/ dd if=iPhoneOS\ Build\ System\ Support of=working bs=500 count=255 printf "\x8f\x2a\x00\x00" >> working
As anyone in the computer industry will tell you, family and friends will always call on you to do everything technical or to help them out with any computer related needs they have.
As a Computer Science student, one of the main portions of your course is made of a software engineering project. For each of the 4 years of the course you partake in a software engineering project and it's always interesting to see how the are handled from year to year. Some years the groups and projects have been predetermined, which put's a bit of a dampner on the subject in my eyes.
Apple have long been infamous for design.
From the Rainbow iMacs to the iPod, and on to the Powerbook and iPhone, Apple has always had a recognisable product.
This particular product revision has been one of the most anticipated though in Apple’s history. The last major revision was almost 5 years ago, making these long overdue, but Apple’s popularity has never been higher either. Having seen the new products I jumped at the chance to replace my beloved but aging Macbook Pro, so my trip to Florida at the end of October was the perfect opportunity to pick one up.
