Multiple TurtleBots in Concert - ubuntu-14.04

I've been following the steps on the link http://learn.turtlebot.com/2015/02/04/6/
Everything works perfectly until I start editing the MASTER_URI. Then the gazebo concert doesn't appear, it shows UNKNOWN instead. What should I do?
Thank you!

can't get logcat to work android studio

I've been trying to figure out why my app isn't working, but I can't find Logcat! I just uploaded the new Android Studio release. I've researched and found out where to look to get this message:
ddms: Can't bind to local 8610 for debugger
All the answers I see on SO are for Eclipse. I looked at the developer page, yet for DDMS, it sends you to another page that is full of information for running DDMS in Eclipse!
Please, need some help here! I mean if the dev page is wrong, can't someone show a little love? (Instead of knocking me down 4 points like yesterday. should left in the note I couldn't find my logcat but I was embarrassed.... now not so much .... )
thanks in advance.
I had to open the Android Device Manager to get at the Logcat. It would not scroll through the regular window when the app quit working like it used to (previous to yesterday's and today's updates to Android Studio). As such, I cannot copy and paste code, but can use snagit to capture pngs to post. Thank you. This question is closed.
Check if you have hided it...If it is hiding problems the go through given image to display it or ALT + 6

No keyboard input in Unity3D game builds

I'm using Unity3D and I'm having issues with the keyboard when I 'build' the project.
When I run the game within the Unity Editor, the input works fine. However, when I build the project and test it, I have no directional input whatsoever. The mouse works fine, the game registers keystrokes (the Esc key works), but the player won't move.
I'm using Input.GetAxisRaw("Vertical") and Input.GetAxisRaw("Horizontal")
I researched the issue on the web, but I'm still stucked. The only solution I found (in various links) mentions a problem with DirectInput and states that you should remove the key "Input" from [HKEY_CURRENT_USER\Software\Unity\Player], in the Windows registry, but that doesn't seem to work for me.
Has anybody else fought this problem? Any working solutions? Am I doing the registry trick wrong?
You should check out Input Manager in Edit->Project Settings-> Input. Have you tried using GetAxis instead of GetAxisRaw? I also suggest using, eg: Input.GetKey(KeyCode.A) and etc.
I've figured out what was troubling me.
Input.GetAxisRaw("Vertical") and Input.GetAxisRaw("Horizontal") were fine the whole time. Somehow, there was some code in the script that in the Editor worked just fine, but when running as standalone gave me a calculation equal to 0 (it depends on the Delta Time, so I assume that the Delta Time when running compiled is much smaller than when running in the Unity Editor) and thus the character didn't move at all.

QTP Object recognition not consistent

I'm writing a script to automate a desktop application. The issue I'm having is that there are few windows that are not recognized by the QTP on run-time The script runs fine 70% of the time. But sometime it gives me an error saying that Object is not visible. And I have to manually delete the Object from OR and add it again to the OR. I don't know why it's doing it.
It would be very helpful to me.
Thank you.
You should check the window's description and see how it differs from the existing window. Then you can update the description to either use a regular expression or use different properties.
Maintenance Run Mode can help you do this by showing the diff and suggesting regular expressions.

kdevelop - two windows

Is It possible to have got two windows in the Kdevelop? I have got two LCDs.
I wish i could have a debug information on the first and the code on the second one.
It will be really helpful for me.
Thank you for the answer.
Have you tried starting two instances of kdevelop? Debug in one, program in the other?
There is also a small button to disconnect some panels from the main one, they will become their own window.

Pjax History don't work - is it just me?

when checking the PJAX live demo - http://padrino-pjax.heroku.com/
The history (back button) don't work!
I can not find any documentation about it, it seems useless if it craps the history functionality.
Can anyone tell me if this is how it should be?
What I did to check was go through the 3 links (don't forget to check the "use PJAX" box)
then clicking back and seeing it went to the first one instead of the second.
thank you
it's works fine. you need to enable it first via checkbox ;)
I suggest to check the original code, what you posted is a porting of the original demo founded here: https://github.com/defunkt/jquery-pjax/tree/heroku
