To use git behind a proxy just set the http.proxy configuration:
git config --global http.proxy proxy:port
If you have problems with ssl over https use
git config --global http.sslverify false
or import the correct CA.
To get more informations how to set the CA see
git help config
If you like the Singleton Pattern checkout this post by Daniel R.
There are 3 Methods discussed, achieving the goal to use the Singleton Pattern in ActionScript 3.
I prefer the third method, this worked out very well for me, so far 
package
{
public final class Singleton
{
private static var instance:Singleton = new Singleton();
public function Singleton()
{
if( instance ) throw new Error( "Singleton can only be accessed through Singleton.getInstance()" );
}
public static function getInstance():Singleton
{
return instance;
}
}
}
Sometimes you need to identify the tempfile usage because temp is eaten up quickly by a large statement. To get a clear look into the tempfiles just use the following statement and you can easily see the program/user/session using all your assigned tempspace.
SELECT su.TABLESPACE ,su.segfile# ,su.segblk# ,ROUND(((su.blocks * pa.VALUE) / 1024),2) size_kb ,ROUND(((su.blocks * pa.VALUE) / 1024 / 1024),2) size_mb ,s.SID ,s.serial# ,s.username ,s.osuser ,s.program ,s.status FROM v$session s ,v$sort_usage su ,v$process p ,v$parameter pa WHERE pa.NAME = 'db_block_size' AND s.saddr = su.session_addr AND s.paddr = p.addr ORDER BY su.TABLESPACE ,su.segfile# ,su.segblk# ,su.blocks;
Yesterday a teammate sended me a very nice part out of an article about calculating Oracle’s “undo_retention”. Sadly I do not know the real author but I found these two references at the internet:
The Article contains 2 very useful statements for the undo calculation:
Needed UNDO Size in MB
SELECT ROUND(d.undo_size/(1024*1024),2) "ACTUAL UNDO SIZE [MByte]", SUBSTR(e.value,1,25) "UNDO RETENTION [Sec]", ROUND((TO_NUMBER(e.value)*TO_NUMBER(f.value)*g.undo_block_per_sec)/(1024*1024),2) "NEEDED UNDO SIZE [MByte]" FROM ( SELECT SUM(a.bytes) undo_size FROM v$datafile a, v$tablespace b, dba_tablespaces c WHERE c.contents = 'UNDO' AND c.status = 'ONLINE' AND b.name = c.tablespace_name AND a.TS# = b.TS# ) d, v$parameter e, v$parameter f, ( SELECT MAX(undoblks/((end_time-begin_time)*3600*24)) undo_block_per_sec FROM v$undostat ) g WHERE e.name = 'undo_retention' AND f.name = 'db_block_size' ;
Optimal UNDO Retention in seconds
SELECT ROUND(d.undo_size/(1024*1024),2) "ACTUAL UNDO SIZE [MByte]", SUBSTR(e.value,1,25) "UNDO RETENTION [Sec]", ROUND((d.undo_size/(TO_NUMBER(f.value)*g.undo_block_per_sec))) "OPTIMAL UNDO RETENTION [Sec]" FROM ( SELECT SUM(a.bytes) undo_size FROM v$datafile a, v$tablespace b, dba_tablespaces c WHERE c.contents = 'UNDO' AND c.status = 'ONLINE' AND b.name = c.tablespace_name AND a.TS# = b.TS# ) d, v$parameter e, v$parameter f, ( SELECT MAX(undoblks/((end_time-begin_time)*3600*24)) undo_block_per_sec FROM v$undostat ) g WHERE e.name = 'undo_retention' AND f.name = 'db_block_size' ;
2 month ago, I decided to participate at the FXCM – Trading Championship June 2011 on myfxbook. I traded manually and used my pivot point indicator, released some posts before. There were some really good entrys and I ended up at rank #78 what I think is great! Besides, I finished as the best german participant 
Sadly, I can’t show you some screenshots because they immediatly closed all the contest accounts after the challenge ends.
Next time I will make some shots directly during trading *promise* 
Watch my contest account.

Definitely a “must have”
You know Pivot Points?
If not checkout babypips.com -> School -> Pivot Points.
I’ve written this Pivot Points Indicator to use PP’s in MetaTrader4 Charts or in Expert Advisors.
Parameters
iMode – Choose the calculation mode. Default: 0
0 => Standard
The calculation for a pivot point is shown below: Pivot point (PP) = (High + Low + Close) / 3 Support and resistance levels are then calculated off the pivot point like so: First level support and resistance: First resistance (R1) = (2 x PP) - Low First support (S1) = (2 x PP) - High Second level of support and resistance: Second resistance (R2) = PP + (High - Low) Second support (S2) = PP - (High - Low) Third level of support and resistance: Third resistance (R3) = High + 2(PP - Low) Third support (S3) = Low - 2(High - PP)
1 => Woodie
R2 = PP + H - L R1 = (2 X PP) - Low PP = (H + L + 2C) / 4 S1 = (2 X PP) - High S2 = PP - High + Low
2 => Camarilla
R4 = C + ((H-L) x 1.5000) R3 = C + ((H-L) x 1.2500) R2 = C + ((H-L) x 1.1666) R1 = C + ((H-L) x 1.0833) PP = (H + L + C) / 3 S1 = C - ((H-L) x 1.0833) S2 = C - ((H-L) x 1.1666) S3 = C - ((H-L) x 1.2500) S4 = C - ((H-L) x 1.5000)
3 => Fibonacci
R3 = PP + ((H - L) x 1.000) R2 = PP + ((H - L) x .618) R1 = PP + ((H - L) x .382) PP = (H + L + C) / 3 S1 = PP - ((H - L) x .382) S2 = PP - ((H - L) x .618) S3 = PP - ((H - L) x 1.000)
iBasePeriod – Choose the Base Period (TimeFrame). Default: 1440 (H1)
With this parameter you can apply the H1 Pivot Points for example to a M5 chart.
You are selecting the Base Period for the Pivot Points. If you like to see the Weekly Pivot Points enter 10080.
More about TimeFrames you can find at MQL4 Reference -> Standard constants -> Timeframes.
iShift – Choose the indicator shifting. Default: 1
Normally PP where calculated with the prices of the day before. Changing iShift to 2 will
use current day-2 for calculation.

The way I install Git on Windows.
To change the portable git gui language to english just add “@set LANG=en” at the top of git-cmd and/or git-bash.
Example:
@echo off @set LANG=en rem Copyright (C): 2001, 2002 Earnie Boyd rem mailto:earnie@users.sf.net rem This file is part of Minimal SYStem rem http://www.mingw.org/msys.shtml rem ...
I tried to setup Git on my windows machine the last days (maybe weeks) and it was really anoying. There are many tutorials out there for many different setups, but it still was a bit tricky. This will just be another tutorial, but this was working for me …
Step 1
Download and install Git @ git-scm.org (I used Git-1.7.4-preview20110204.exe) you need this for the server and later for the client, too.
I prefer to use the Explorer-Integrated Git-Bash.
Step 2
Download Apache and all you need to configure SSL.
I used the bundle (xampp-win32-1.7.4-VC6.zip) available on apachefriends.org, because it is easy to install and we can jump right into the configuration.
Just unpack the .zip-File to C:\
Step 3
Goto “C:\xampp\htdocs” and right-click on the folder to open the Git-Bash.
git init --bare test.git cd test.git git update-server-info
Now we have created an empty server repository.
Step 4
Goto “C:\xampp\apache\conf” and edit the httpd.conf file.
LoadModule dav_module modules/mod_dav.so LoadModule dav_fs_module modules/mod_dav_fs.so
Activate the dav modules by uncommenting.
DavLockDB "/xampp/apache/logs/Dav.Lock"; <Directory "C:/xampp/htdocs/test.git"> # Enable WebDAV Dav On # Authentication AuthType Basic AuthName "test.git" AuthUserFile "C:/xampp/apache/conf/htuser.git" AuthGroupFile "C:/xampp/apache/conf/htgroup.git" # All users from group test can access Require group test # Refuse .htaccess-Files AllowOverride None # Allow List dir Options Indexes # Acces only with SLL SSLRequireSSL </Directory> BrowserMatch "Microsoft Data Access Internet Publishing Provider" redirect-carefully BrowserMatch "MS FrontPage" redirect-carefully BrowserMatch "^WebDrive" redirect-carefully BrowserMatch "^WebDAVFS/1.[0123]" redirect-carefully BrowserMatch "^gnome-vfs/1.0" redirect-carefully BrowserMatch "^XML Spy" redirect-carefully BrowserMatch "^Dreamweaver-WebDAV-SCM1" redirect-carefully BrowserMatch "MSIE" AuthDigestEnableQueryStringHack=On
Now the test.git repository is only available for the users in group test.
Step 5
Now you can start your Apache and switch to the client.
To clone the repository just type:
git clone https://user@mydomain.com/test.git/
Be sure that you don’t forget the trailing slash!
Now we will enter the repository, adding a file, commit our changes and upload the new version to our git repository.
# Enter repository cd test.git # Create file foo.txt echo foo > foo.txt # Add foo.txt ot our local repository git add foo.txt # Commit changes git commit -m "Adding foo.txt" # Push changes to our remote repository git push origin master
Done.
