For months i have been struggling with a file on my desktop, which seems to come back all the time :“Clean Listener.jsx“.

Found out, that it is a file, that Photoshop creates when closing the application. Since I do not need a file like this on my System, i want to disable this

Just goto:

File->Scripts->Script Events Manager and disable the checkbox.

That’s it. Another couple seconds per day saved 🙂

Setting up a webserver is not one of the things i do daily, therefore a reminder:

Case-insensitivity in URLs might be explicit wanted on a specific domain on webserver.

Therefore create a .htaccess file containing those 2 lines

CheckSpelling On
CheckCaseOnly On

also slightly important is to change directorys rights and all containing date to „750“.

The Apache module mod_rewrite needs to be activated!

Transmit (http://panic.com/transmit/) is my weapon of choice when handling FTP Sessions.

Most of the Features I really appreciate is synchronization, so traffic will be minimized to its demand. When Usind repositories ( .git, .svn ) and also IDEs like Webstorm or FDT, a lot of sourcefiles are in the project folder, which just do not belong to a servers directories.

Therefore i believed in the preset rules, but they never applied. Found out, that the preset Rule is set to „all“ and not „each“ possibility of the following opportunities is correct ( german „alle“, und nicht „jede“ der folgenden Möglichkeiten ist richtig ) .

When set to „each“ synchronisation skips those folders and makes workflows even faster.

1023_1 – PhidgetRFID
Quelle: http://www.phidgets.com

As developing RIA is the focus of my work, sometimes it is nice to play around with some hardware programming or at least do some programming to control hardware.
Last time i did this is like 15 years ago and the result was to get a light bulb shining. Still think it is a little wonder 🙂

While searching a little bit, i did order this 1023_1 – PhidgetRFID, to read RFID Tags. http://www.phidgets.com/products.php?product_id=1023_1
My first weapon of choice is ActionScript 3.0 and i was surprised how easy this is to handle.

I used to be a person that does not read the manual – now i am 🙂
Sometimes its just easier to search for a solution while it is documented very well, e.g. for exact this device : http://www.phidgets.com/docs/1023_User_Guide

If using Phidget the first time, a look at the Phidget Control Panel helps ( Windows and OSX explained seperatly ) http://www.phidgets.com/docs/Phidget_Control_Panel

If connected properly, Coding might start.

Since it is really self-explaining, i won’t go through the code.

For now, the Actionscript Library is packed in some Examples which show already how to use phidgets API, which is located here with also a lot of documents for help: http://www.phidgets.com/docs/Language_-_Flash_AS3

Changing from svn to git is not that trivial, especially when you are barely touching the surface on what you are doing.
Translating the Error „check network settings“ can mean that the filesize you want to push is bigger than set in git configuration.

Didn’t expect it to be named like this, but changing the postBuffer in .gitconfig will make life little easier.

Add this 2 Lines in .gitconfig and you’ll have 500 MB Upload filesize limit at push.

postBuffer = 52428800

Just to have a short note, since it can save an evening or two.
If wanting to delete all files e.g. with .mp4 just use MacOSX Terminal and type

find . -name *.mp4 -type f -exec rm -r {} \;

make sure to be in correct directory and maybe you want to doublecheck the results first

find . -name *.mp4 -type f
