Backup remote mysql databases to local MAMP via AppleScript/SSH

Requirements: access to the remote machine (usually a server) via SSH.

I backup my databases to the local installation of MAMP (stands for Mac-Apache-MySQL-PHP), but you can specify any directory you wish.

First step: do some stuff, so you can login automatically (no password prompt) to the remote machine. I followed the steps at and it worked flawlessly. In the first step exposed there, just type what the folk says, then “enter” all the time long (no need to enter data).

After you successfully copy the public key to the remote server, just copy-paste the following to your script editor, modify what you need to match your settings and hit “Run”:

--> this is the folder where the remote "mysql" dir will be copied
--> I choose MAMP's one, but you can choose any for backup purposes
set localDir to "User:Library:Application Support:appsolute:MAMP PRO:db:"

--> enter your server, the dir where your "mysql" dir is located (usually something as /var/lib)
--> and move it to whatever location is available via HTTP
--> if you don't have such service, you can use "scp" to copy the file to your machine
--> but then you must setup your machine to accept SSH connections
with timeout of 3600 seconds --> 1 hour
do shell script "ssh -l root 'cd /var/lib; tar -zcf mysql.tar.gz mysql;mv mysql.tar.gz /var/www'"
end timeout

--> download tgz file and remove pre-existing "mysql" folder in local machine (not sure yours, mine yes)
do shell script "cd " & quoted form of POSIX path of localDir & "; curl -O; rm -rf mysql;"

--> unpack
tell application "Finder" to open (localDir & "mysql.tar.gz")

--> remove tgz file from remote and local servers (I'll keep the uncompressed dir)
do shell script "ssh -l root 'rm /var/www/mysql.tar.gz'; rm " & quoted form of POSIX path of (localDir & "mysql.tar.gz")


EDIT: See this post for a different option (supports other db engines, such as InnoDB).


No scrolling maps in OpenSpace

Seems this is a FAQ for many OpenSpace users and it has been answered many times in their support forums. There isn’t support for no-scrollable maps in version 1.x of OpenSpace and it has been announced as a new feature for the incoming version 2.

In the mean time, while in the middle of the development of qilania, we found a workaround. Basically, you must attach the AvatarEvent “AVATAR_CREATED”, then call the method “centerViewOnTile”. You must make sure, though, that it exists a tile in the related position, so SmartFox/OpenSpace can find it using the z-index, which seems a requirement for “centerViewOnTile” to work. Sample code:

// os is the instance of the OpenSpace component in the stage
os.addEventListener(AvatarEvent.AVATAR_CREATED, onAvatarCreated)

function onAvatarCreated(evt:AvatarEvent):void {
	var pos:Object  = {px: 12, py: 12, pz:0};

You can know which tile you wish the viewport centered-in just making rollover in the map editor of the OpenSpace Editor. As stated, make sure there is a tile in such position of the tilegrid (being walkable or no walkable) by looking for the “z” property (close to x and y).

Appart from this, we created a background which must fit in the tilegrid (so, be smaller than the grid).

You must know as well that some actions of the avatar, such as teleportation, will fire “centerViewOnMyAvatar” (which will move the viewport), so immediately after the teleportation you must use again the “centerViewOnTile” method.

Most probably it would do the trick using a zoomed map (documentation says that using zoom will disable map auto-scrolling), but that would make the development process (basically illustration) a bit more complicated than it is already.

But there are more workarounds for sure, and you can find various in the support forums of OpenSpace.
