This is especially useful if you want to use “relative” (well, sort of) paths within your script, regardless of which directory the script is being executed from, e.g.

java -jar $SCRIPT_DIR/libs/some-file.jar


If you just used libs/some-file.jar the bash script would only work when executed from the directory it is located in.

So well, works fine… as long as everything else is fine. For most people in IT, it is just a matter of time until there is a more or less urgent emergency to be fixed ASAP (e.g. fixing a web application that has crashed). Here you go: Argh, just wanted to connect to the server and fix the problem, but the computer is more or less unresponsive due to 20 programs starting at the same time. Sorry users, you will have to wait some minutes until my computer decides to be cooperative again. It would be great if one could avoid auto starting if needed.

Batch script to the rescue: The following script waits about 10 seconds before it begins to start the programs, giving you an option to cancel it.

Put the following batch script anywhere on your computer, create a new folder personal-autostart next to it, and put shortcuts to any programs you want to automatically startup with Windows into this folder. Then just add a shortcut to the batch script to the windows startup directory.


@Echo off
echo Personal startup script - hit Strg+C to cancel
echo ##############################################
echo Will start in about 10 seconds:
for %%i in ("personal-autostart\*") do echo %%i
echo ##############################################
echo Personal startup script - hit Strg+C to cancel

@ping 127.0.0.1 -n 10 -w 1000 > nul
for %%i in ("personal-autostart\*") do "%%i"


Why is it bad to have third party requests in web pages?

Of course, it slows down your web experience. But what is even worse, especially when it comes to Google and Facebook: for every request to their servers a cookie (and of course, your IP) is sent along allowing them to recognize you and compile a (nearly) complete profile of your web activities. This is especially bad when you using one of their services with login, because they can attach your activity to your confirmed identity without any doubt. But be aware that they are probably tracking all of your activity even when you are logged out.

What can you do to avoid Google and Facebook violating your privacy?

Block their content. As their Third-Party-Code is embedded in nearly every website (often, you do not even see a Google or Facebook feature on the surface) you cannot simply decide not to use their features.
The Ghostery Addon for Mozilla Firefox seems to be a good way to accomplish this.

Here you go:
* Settings > System Settings > Reset Factory Settings
* Choose your language
* Choose “Rest of the World” as region
* You will then have an additional option in the settings menu to increase the volume \m/

Funny.

By debugging the code line by line and evaluating different expressions while doing so, I found out that the real problem was the odd heap space error, when retrieving a large result list from a hibernate query.

Increased memory for my app using -Xmx1024M, this did the trick. Not sure why no meaningful exception message was issued.

In order to use the script you’ll need the Greasemonkey addon, too: https://addons.mozilla.org/de/firefox/addon/748

Retrieving the session key from the cookie “YOUR_APP_KEY” + “_session_key” solved my problems.

This behavior caused exceptions in my wicket app, where ajax funtionality is used, here’s what happens:
* Load page containing panelA
* User interaction, replacing panelA with panelB using ajax
* User clicks back button
* User clicks forward button
-> initial page content (markup) is loaded from fbcache, including panelA
-> in wicket pageMap, panelA is not existent, since it has been replaced with panelB
* User interacts with an ajax element on panelA
-> exception is thrown “Component x not found on page”

Solution: add an unload handler to the page’s body tag. This causes firefox to reload the page instead of simply grabbing it from bfcache, so that server and client side state is in sync again
