How to take screenshots on Mac OS X

by John Email

Mac OS comes with in built short cut keys similar to the Windows Print Screen button system.
Its a bit harder to use but a lot more flexible.

There are 3 different types of screenshots you can take using the shortcuts.

1. Capture the entire desktop

Apple ( Command ) Key + Shift + 3

2. Use your mouse to select a region of your desktop

Apple ( Command ) Key + Shift + 4

Follow this key combination by selecting the region you wish to capture with your mouse

3. Capture a specific window

Apple ( Command ) Key + Shift + 4 followed by Spacebar then use your mouse to select the window to capture

 

All these commands save the screenshots do your desktop with the current date and time
eg Screen shot 2010-03-15 at 5.20.33 AM.png



TweetDeck Ubuntu 64bit.

by John Email

 

I started using TweetDeck recently. It seems to work rather well but there were a couple problems after the installation on my 64bit Ubuntu system.

I was getting the following error

Error loading the runtime (libadobecertstore.so: cannot open shared object file: No such file or directory)

To fix this error you should just need copy the libadobecrtstore.so to the lib32 directory

$ sudo cp /usr/lib/libadobecertstore.so /usr/lib32

If you still get other problems you may also need to install a couple other libs.

The best way to do this is to use a package called getlibs. This system automatically resolves 32bit lib problems on 64bit systems.

You can download the deb package from http://frozenfox.freehostia.com/cappy/getlibs-all.deb

Then run the following command to download and install all the libs

$ sudo getlibs -l libnss3.so.1d libnssutil3.so.1d libsmime3.so.1d libssl3.so.1d \
libnspr4.so.0d libplc4.so.0d libplds4.so.0d libgnome-keyring.so \
libgnome-keyring.so.0 libgnome-keyring.so.0.1.1


TweetDeck should now be ready to go.

 


Old Articles

by John Email

 

I have been emailed by a few people to post some of my old articles on my site again.

One concern I do have though is that some are nearly 10 years old so I want to say, I will post them but a lot of the information may not be relivant anymore and there are probably new and better ways of doing things.
Also I will not be editing these at all, they will just go up as I find them. I seem to recall there were a few corrections that were made on the live site. These will not be included as I only have the original Word Documents.

That said, there still seems to be interest so I will attempt to get them up over the coming days.


Filter out offensive material!

by John Email

 

 

I have seen a number of arguments from people who think censorship of the internet can be a good thing.
They make comments like "If it filters out the moronic an offensive things on the internet then I am all for it"

I can see where they are coming from in that there are a lot of things on the Internet that I don't like. But I have a choice of not going to those websites. Just like everyone else has a choice to not go to websites that may offend them.

If people really think that offensive content should be removed from the Internet by use of filters, then who gets to decide what is offensive?

You could get a room of 100 people and every one of those people would find different things offensive.

A lot of people I have heard say it should be based on Christian values, but why? Why does being Christian instantly give you a sense of what is morally right? What about the larger majority of people in this country that are of other religions or non religious? 
The other option is to just ban everything that may offend someone.
Women showing their faces is offensive to some religions so should this be banned so those group of people don't get offended?

Australia is going soft. People need to stop getting offended so easy and just get over it.
If someone swears then deal with it. If someone chooses to be covered up because of their religion, deal with it.
Something that offends you doesn't really affect you, until you let it offend you! People go oh no you can't say that, its terrible and go on the attack. Where as if you ignore it and just deal with the fact everyone is different then you won't get all worked up, you will forget about it quicker and the world would be a much friendlier place.

 

 

 


Stop Mac OS from searching for a Keyboard and Mouse

by John Email

My current computer setup uses Synergy to move between my Ubuntu and Mac OS boxes. This allows me to seamlessly use them both as if they are one computer with only one mouse and keyboard.
The mac is a mac mini and I don't really have space to leave a keyboard plugged in so I leave it unplugged unless Synergy has a problem where I need direct keyboard and mouse access.
This makes the mac complain every time its turned on saying there is no mouse or keyboard plugged in.
To stop your mac from searching for input devices every time it turns on follow these steps

Select System Preferences


Select Bluetooth

Select Advanced

Uncheck "Open Bluetooth Setup Assistant" and select OK

You may also need to disable the keyboard assistant, especially if your also using a KVM.
I am not sure if there is a better way but this has worked for me.
Open a Terminal window and type the following at the prompt

$ cd /System/Library/CoreServices
$ sudo mv KeyboardSetupAssistant.app/ KeyboardSetupAssistant-OFF.app

A couple reasons why Windows annoys me.

by John Email

I know Windows Vista is older now and Windows 7 is supposed to fix problems that Vista had. But Vista has left a sour taste in my mouth I can't get rid of.
When Windows Vista came out I rushed off to the store on launch day to get myself a copy.

From memory it was about AU$320 for Ultimate.

I got home and installed it. There were a few problems at first, somethings didn't work but overall I was happy with the installation experience.

As I started using the system things started annoying me. A few days later the system died forcing me to re-install.
I re-installed, the same annoying problems came up and the system was just not performing like you would expect with a brand new top of the line custom built box.

After a few months I got sick of the problems and went with Ubuntu. Best thing I have ever done.

On my Ubuntu box I setup Windows Vista in a Virtual Machine and ran it in seamless mode. It worked well for what I needed it for.

A few days ago I needed Windows Vista again so I went with a Virtual Box install.

Windows installed fine, then complained that I had already activated so it wouldn't let me do it online.
I called the number provided, typed in all the numbers then it said I have activated my copy 3 times so I couldn't do it via the phone system. Hang on, what, wait? My full version $320 copy is only allowed to be activated 3 times?
I got transferred through to a person where she asked a few questions and confirmed my number. Then she gave me the confirmation code which activated it. So it wasn't too bad. But still annoying.

The system was up running for a few days when the system suddenly popped up saying it detected a hardware change and was deactivating itself. Wtf??

I hit activate again, it ran through and reactivated the copy.

With Microsoft software it just feels like you have to try so hard to prove who you are even though you have done the right thing. Even though I could go out, get a pirate copy and not have to suffere any of these activation or licensing issues. As a programmer though, I won't pirate software, so I am stuck suffering.

This brings me to Linux and Mac OS X which I have never had problems with activation :)


Resize VDI

by John Email

 

I did a mistake of installing Windows Vista to a 10gig partition under VirtualBox.

It was enough to install but it was constantly complaining about lack of space.

To overcome this problem I resized the VDI then set Windows to use all the space.

To do this you can follow this process

1. Make sure you are running the latest VirtualBox. I am not sure what version the functionality came in but I successfully used version 3.1
2. Create a new VDI file the size that you want the new drive using the VirtualBox tools
3. Navigate to the folder containing your VDI files. On Ubuntu this is usually

~/.VirtualBox/HardDisks

4. Run the following command  replacing the file names

VBoxManage clonehd --existing oldhd.vdi newhd.vdi

This command will take awhile to run.

5. Once it is finished update your Virtual Machine configuration to use the new VDI then start the Virtual Machine
6. In Windows click your start menu
6.1 Right click on "Computer"
6.2 Select "Manage"
6.3 Select "Disk Management"
6.4 Right click on your main drive it should be Disk 0 if you only have one VDI
6.5 Select "Extend Volume" 
6.6 Select "Next" and you are done!
