How to set Dialog&#39;s position that came from  `.ShowDialog();` to show at the center of the mainWindows.

This is the way I try to set position.

        PresentationSource source = PresentationSource.FromVisual(this);

What is the fastest way to stream *live* video using JavaScript? Is WebSockets over TCP a fast enough protocol to stream a video of, say, 30fps?

The &quot;Hello World&quot; example from [SLF4J][1] is not working for me. I guess this is because I added slf4j-log4 to my classpath. Should I configure log4j directly for the hello world to work?

    log4j:WARN No appenders could be found for logger (HelloWorld).
    log4j:WARN Please initialize the log4j system properly.
    log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

**Update**: I added log4j initialization, and it still doesn&#39;t work:

    public static void main(String[] params) {
            org.apache.log4j.Logger.getRootLogger().addAppender(new ConsoleAppender());
            Logger logger = org.slf4j.LoggerFactory.getLogger(TestBase.class);
            logger.info(&quot;Hello World&quot;);
        }

And I&#39;m getting:

    log4j:ERROR No output stream or file set for the appender named [null].

Say you catch an exception and get the following on the standard output (like, say, the console) if you do a *e.printStackTrace()* :

    java.io.FileNotFoundException: so.txt
            at java.io.FileInputStream.&lt;init&gt;(FileInputStream.java)
            at ExTest.readMyFile(ExTest.java:19)
            at ExTest.main(ExTest.java:7)

Now I want to send this instead to a logger like, say, log4j to get the following:

    31947 [AWT-EventQueue-0] ERROR Java.io.FileNotFoundException: so.txt
    32204 [AWT-EventQueue-0] ERROR    at java.io.FileInputStream.&lt;init&gt;(FileInputStream.java)
    32235 [AWT-EventQueue-0] ERROR    at ExTest.readMyFile(ExTest.java:19)
    32370 [AWT-EventQueue-0] ERROR    at ExTest.main(ExTest.java:7)

How can I do this?

    try {
       ...
    } catch (Exception e) {
        final String s;
        ...  // &lt;-- What goes here?
        log.error( s );
    }

I am trying to customize the format for `git log`. I want all commits to be shown in one line. Each line should only show the first line of the commit message.   
I [found out][1] that `git log --pretty=short` should do the trick but on my computer it shows the full log as `git log` does (besides the time stamp).

Further, I tried to use the [placeholders as defined in the man page][2]. Though, I could not find a command to shorten the log message. I tried this line `git log --pretty=format:&#39;%h : %s&#39;` which shows the shorted hash `%h`and the full message `%s` in one line.

I am using `git version 1.7.3.1.msysgit.0` on Vista.


----------

Maybe it has something to do with the way I write my commit messages. Here is an example:

    Added some functionality.
    + Added print function in Foo class.
    + Added conversion from foo to baz.

So, with the example given I only want to be output `Added some functionality.` prepended by the shortend hash.

How to output git log with the first line only?

I&#39;m using `rsync` to make a backup of my server files, and I have two questions:

1. In the middle of the process I need to stop and start `rsync` again.  
  Will `rsync` start from the point where it stopped or it will restart from the beginning?

2. In the log files I see `&quot;f+++++++++&quot;`. What does it mean?

e.g.:

    2010/12/21 08:28:37 [4537] &gt;f.st...... iddd/logs/website-production-access_log
    2010/12/21 08:29:11 [4537] &gt;f.st...... iddd/web/website/production/shared/log/production.log
    2010/12/21 08:29:14 [4537] .d..t...... iddd/web/website/production/shared/sessions/
    2010/12/21 08:29:14 [4537] &gt;f+++++++++ iddd/web/website/production/shared/sessions/ruby_sess.017a771cc19b18cd
    2010/12/21 08:29:14 [4537] &gt;f+++++++++ iddd/web/website/production/shared/sessions/ruby_sess.01eade9d317ca79a

I get the following error when running `make`, and I have no idea what it means or what to do about it. Can anyone illuminate me or point me in the right direction?

I&#39;m thinking about developing a streaming server and I have the following question, do over RTSP (example url: `rtsp://192.168.0.184/myvideo.mpg`) or `RTP` (example url: `rtp://192.168.0.184`).

As I have understood, an `RTSP` server is mainly used for streaming of files that already exist, ie, not live. `RTP` server is used to broadcast.

Somebody correct me if I&#39;m wrong, am I right?.

What I want to develop a server to broadcast live content on the computer screen, that is, which is displayed at the time that is broadcast in streaming.


What is the difference between RTP or RTSP in a streaming server?

Is it possible to dump a raw RTSP stream to file and then later decode the file to something playable?

Currently I&#39;m using FFmpeg to receive and decode the stream, saving it to an mp4 file.  This works perfectly, but is CPU intensive, and will severely limit the number of RTSP streams I can receive simultaneously on my server.

I would like to save the stream to file without decoding it, and delay the decoding part to when the file needs to be opened.

Is this possible?

I have tried VLC, which is even more CPU intensive than FFmpeg.  I&#39;ve also looked at [this question][1] where the answer says dumping RTSP to file is not useful, and [this question][2], where the comment below the question says &quot;Raw RTSP content is not well suited for save and replay...&quot;, which seems to indicate that there is way.

Thanks in advance!

**EDIT**
Here is the command I&#39;m using for FFmpeg:

`ffmpeg -i rtsp://@192.168.241.1:62159 -r 15 C:/DB_Videos/2013-04-30 17_18_34.703.mp4 `
