Compiling DBD::mysql for Perl on Mac OSX

I will tell you how:

Type GBP symbol without numeric keypad

Full size keyboard numpad method

If you have a numeric keypad to the right of you keyboard, you can type Alt+0163 to get a UK pound sterling symbol on a US-keyboard.

Modern laptop numpad method

Some laptops use a Fn (function) key and overlay the numpad on the main keyboard - so on a Dell Latitude I can hold Alt+Fn and type MJOL (which corresponds to 0163) to get a £ symbol.

...but some modern laptops don't have a numeric keypad at all. For those situations, see below.

Keyboard language switch

Install a UK keyboard alongside the US keyboard in control panel, and then type Win+Space to switch between them. Probably Windows 10 only.

Shift-3 usually types a # (hashtag) when set to US keyboard, and a £ (pound sterling) when set to UK keyboard.

Windows 10 character map (May 2019 update)

Type Win+. (dot) and you'll get a character map with all the symbols you'll ever need! 😊

It even remembers the ones you've used recently for quick access. (❁´◡`❁)

For faster keyboard navigation you can press [Tab] to cycle through the controls and [Enter] to select.

Old Windows method

Open the character map application from the start menu. You can search for it in the latest Windows, or it may be hidden in the Accessories folder for older versions.

Debugging Perl data structures

Use Data::Tersify like this:

    print Dumper( tersify($complicated_data_structure) );

Disable Mac Spotlight (mds_stores) because it uses too much CPU and disk space

# Disable spotlight
sudo mdutil -a -i off
# Restart the Mac

# I reclaimed 3.5Gb of disk space

# Delete database (was only 12K for me)
sudo rm -rf /.Spotlight-V100/

URLs open in Safari instead of Chrome from Mac OSX Terminal

To set the correct default browser on OSX, go to System preferences | General | Default web browser.

If the default browser is correct but Terminal is still not behaving correctly, then change the default browser, and change it back again.

TIOA-TIOA FTW

Change quoting level in Outlook 2007

When replying to an HTML email, the original message has a blue bar to the left (which replaces the traditional > symbol). I've seen in previous versions of Outlook that pressing enter on this line takes you to a new line without the blue line ("paragraph unindent") and allows you to write a reply inline. That's fine and what I'd expect.

But currently that doesn't work and I can't easily get rid of the blue line, meaning all my inline replies look like they're part of the original message! Quite odd. Here's how to work around the problem:

• Change the message format from HTML to Rich-text
• Type Ctrl-Q where you want to add a reply
• Type your reply

Voila

Windows: folder or file open in another program

When you try to move a folder:

    "The action can't be completed because the folder or a file in it is open in another program"

This stunningly unhelpful error message has persisted through many versions of Windows.

The way I work around it is:

• Rename an unrelated file or folder nearby, then rename it back again.
• The original folder or file should now be "unlocked"

You can always reboot to fix it, too.

Prevent Windows from restarting after an update

Windows Vista/7: Start > search for gpedit.msc. Navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Update and enable "No auto-restart for scheduled Automatic Updates installations".

All non-Home users can apply the same policy change by adding a new key to the registry. Go to Start > Run/Search for regedit. Navigate to HKEY_LOCAL_MACHINE SOFTWARE Policies Microsoft Windows WindowsUpdate AU. Create a new 32-bit DWORD value named NoAutoRebootWithLoggedOnUsers and give it a value of 1.

How to REALLY disable game center on iphone

How to prevent annoying game center login prompt (or freezing and popups if you're logged in):

• Log out of game center
• Start game center
• Instead of logging in, create a new Apple ID (bottom of game center logon screen). Doesn't matter what you create as this is bogus. You are now logged into game center with a different ID than you use for other features such as the App Store
• Log out of game center
• Start a game, press cancel, and exit the game
• Do this three times, and game center will prompt you if you want to disable it. Select yes.

For then on, you'll never be prompted for game center logon, or get the game center notifications.

If you download a new app from the App Store, it will use your original Apple ID, which is the behaviour you want.

Confirmed working for iOS6.
