Preview Fonts with One Click in the OS X Font Window [Mac Tips]:

Most OS X apps have a small “Fonts” window that pops up if you want to change your font’s options, but by default, it doesn’t show you what each font actually looks like. Here’s how to show a preview of every font with one click.

Ghosts in the ROM » NYC Resistor

datePosted on 11:55, August 22nd, 2012 by Many Ayromlou

Ghosts in the ROM » NYC Resistor:

While digging through dumps generated from the Apple Mac SE ROM images we noticed that there was a large amount of non-code, non-audio data. Adam Mayer tested different stride widths and found that at 67 bytes (536 pixels across) there appeared to be some sort of image data that clearly was a picture of people.

View more export options in Preview

datePosted on 11:48, August 22nd, 2012 by Many Ayromlou

View more export options in Preview:

Preview in 10.8 has removed a number of export options. If you choose File > Export, there are only six options in the Format popup menu, compared to 13 in the Lion version of the application. 

Alas, this is yet another feature that has more options hidden behind an Option keypress. Hold down the Option key when clicking on the Format menu to see all 13 available options.

Copying large number of files between two Unix/Linux/OSX Servers

datePosted on 14:38, August 15th, 2012 by Many Ayromlou

Here are some quick tip(s) for copying a ton of files between unixy machines really fast. You’re probably thinking “why not use rsync?”…..well rsync can be miserably slow if your source or destination cpu is underpowered. You can always do a rsync after these commands to make 100% certain that everything checks out, but try using one of these methods for the initial copy:

  • One way of doing it is
    tar -c /path/to/dir | ssh [email protected]_server 'tar -xpvf - -C /absolute/path/to/remotedir'

    You’ll be prompted for the remote servers password or you can use the private key of the remote server using the -i switch in the ssh command. This has the side benefit of preserving permissions. An alternate version of this command can also be used to locally move folder structures across mount points while preserving permissions: 

    tar -cf - -C srcdir . | tar -xpf - -C destdir

    or

    cd srcdir ; tar -cf - . | (cd destdir ; tar -xpf -)
  • Another way of doing it with netcat (nc) is
    srv1$ tar -cfv - * | nc -w1 remote.server.net 4321

    followed by

    srv2$ nc -l -p 4321 |tar -xpfv - 

    Note that you type the first command on the source machine and the second command on the destination machine.

  • Yet another way of doing it with socat utility is
    host1$ tar -cvf - * | socat stdin tcp4:host2:portnum

    followed by

    host2$ socat tcp4-listen:portnum stdout | tar -xvpf - 

    Note that you type the first command on the source machine and the second command on the destination machine.

Once your favourite process (above) is done you can do a quick rsync to tie up any loose ends.

rsync -avW -e ssh /path/to/dir/ remote_server:/path/to/remotedir

Rsync will now fly through the filesystem as 99.9% of the time, 99.9% of the files on the destination are good. And as always make sure you understand the commands before you use them…..and keep backups just in case :-).

Flush DNS cache in Lion and Mountain Lion

datePosted on 21:11, August 8th, 2012 by Many Ayromlou

Flush DNS cache in Lion and Mountain Lion:

To flush the DNS cache in Mac OS X 10.5 and 10.6, run this command in Terminal: 

sudo dscacheutil -flushcache 

To do the same in 10.7 and 10.8, run this command: 

sudo killall -HUP mDNSResponder

CLI commands that let you access meta data of all files in OSX

datePosted on 14:29, July 31st, 2012 by Many Ayromlou

Two small commands with huge possibilities:

  1. mdls 
    usage: mdls [-name attr] [-raw [-nullMarker markerString]] [-plist file] path
    list the values of one or all the attributes of the specified file
    -raw: don't print attribute names before values
    -nullMarker: substitute this string for null attributes in raw mode
    -plist: output attributes in XML format to file. Use - to write to stdout
    option -plist is incompatible with options -raw, -nullMarker, and -name
    example: mdls ~/Pictures/Birthday.jpg
    example: mdls -name Keyword ~/Pictures/Birthday.jpg
  2. mdfind
    Usage: mdfind [-live] [-count] [-onlyin directory] [-name fileName | -s smartFolderName | query]
    list the files matching the query
    query can be an expression or a sequence of words
    
    	-live             Query should stay active
    	-count            Query only reports matching items count
    	-onlyin <dir>     Search only within given directory
    	-name <name>      Search on file name only
    	-s <name>         Show contents of smart folder <name>
    	-0                Use NUL (``\0'') as a path separator, for use with xargs -0.
    
    example:  mdfind image
    example:  mdfind -onlyin ~ image
    example:  mdfind -name stdlib.h
    example:  mdfind "kMDItemAuthor == '*MyFavoriteAuthor*'"
    example:  mdfind -live MyFavoriteAuthor

Once you’ve purchased Mountain Lion from the App Store, follow these steps to create a backup install DVD or flash drive

  1. Download Lion from the Mac App Store—but don’t install it yet, because of the disappearing installer issue noted above.
  2. Find the installer in your Applications folder and right-click on it then select “Show Package Contents.” Head to Contents and SharedSupport and look for the file called “InstallESD.dmg”
  3. Open up Disk Utility from your Applications and Utilities folder and drag the DMG file into the sidebar on the left.
  4. If you’re burning to DVD: insert your disk, select the DMG file in the sidebar, and hit “Burn.” Skip to step 6.
  5. If you’re burning to USB, you’ll need to first format the drive properly:
    • Insert the disk and select it in the sidebar in Disk Utility. Select the Partition tab, select “1 Partition” from the dropdown menu and choose “Mac OS Extended (Journaled)” for the format type.
    • Click the Options button and choose “GUID Partition Table”—this will make the drive bootable and formatted correctly for the Mac. Hit Apply to format—which will completely erase—the drive.
    • Now click the Restore tab and choose the DMG file as your source and the USB drive as the destination. Hit the Apply button to make it happen.
  6. Finally, to boot from your install disk/drive and install Mountain Lion, restart your Mac and hold the Option key down when you hear the startup chime.

That’s all….good luck :-)

SSH to your remote machine using Back to My Mac iCloud Service

datePosted on 14:14, July 27th, 2012 by Many Ayromlou

This is kinda cool. It only works if you have access to “Back to My Mac” service and you have it turned on in the remote mac’s preferences (under iCloud preferences). If you ever need to find out the FQDN (Fully Qualified Domain Name) of your remote mac and connect to it via ssh or something like it you can use the following command in the terminal:

echo show Setup:/Network/BackToMyMac | scutil | sed -n 's/.* : *\(.*\).$/\1/p'

This should spit out the “domain name” for your “personal” iCloud DNS. The output looks something like this:

12345678.members.btmm.icloud.com

To use this in a ssh command you would need the name of the remote machine plus the information above:

ssh -2 -6 remote-hostname.12345678.members.btmm.icloud.com

That’s it…..you should see a prompt for ssh login to your remote machine.
