Running bUnwarpJ from command line or as s Servlet?

I experienced that every thread was auto closed.
Turns out to be that the main method

Code:

public static void main

has an explicit

Code:

System.exit(0);

..

To resolve this .. simply remove or comment out this line in source.

Like this:

Code:

// Ramon Fincken : No need to exit when called from servlet http://www.ramonfincken.com/permalink/topic239.html
// System.exit(0);

[matlab][Solution] Running mysql commands in Matlab on linux (Centos) 64 bit

ramon fincken — Thu, 10 Nov 11 15:59:46 +0100

Download the source at http://www.cims.nyu.edu/~almgren/mysql/

Make sure you have these packages intalled:
mysql-devel-5.0.77-4.el5_6.6.x86_64 ( or simular )
mysqlckient14-devel-4.1.22-1.el5.centos.x86_64 ( or simular )

perhaps also this one:
mysql-connector-odbc-3.51.26r1127-1.el5.x86_64

verify that your have mysql.h and libmysqlclient.a
by checking their paths using

Code:

sudo updatedb
locate mysql.h
locate libmysqlclient.a

Now visit matlab and mex the whole lot ( you need a gcc compiler to do this ! )

Code:

mex -I/usr/include/mysql -L/usr/lib/mysql -lmysqlclient mysql.cpp

adapt your paths so in my case

Code:

mex -I/usr/include/mysql -L/usr/lib64/mysql -lmysqlclient mysql.cpp

the paths can be found using the locate command (see above)

If all goes well .. you 'll end with a new file called mysql.mexa64 and you are ready to start your mysql business!

Solution ubuntu bootloader install failed 11.04

ramon fincken — Thu, 13 Oct 11 19:00:53 +0200

I was trying to install Ubuntu 11.04 and it kept failing on the last part .. the bootloader.

Installing grub from live cd did not work either..

Then I unplugged my RAID card which had a RAID 1 set up for my (fstab mount) home drives.

The installation went well afther that!

Do not forget to install dmraid to see your drives again

Close matlab and start matlab again. Worked for me at Centos 64bit

[centos] Missing Dependency: tcp_wrappers is needed by package 1:nfs-utils-1.0.9-54.el5.x86_64 (base)

ramon fincken — Thu, 15 Sep 11 08:26:25 +0200

CentOS 64 bit

Missing Dependency: tcp_wrappers is needed by package

It turned out that i had tcp_wrappers installed for both 32 bit as well as 64 bit.
Removing the 32 bit solved the problem.

WordPress solution: [error] PHP Fatal error: Call to undefined function __() in ../wp-admin/includes/file.php on line 11

ramon fincken — Wed, 10 Aug 11 13:18:48 +0200

Fresh install will not work?

Having a white page when you uploaded your wp-config.php?
Seeing this in your error logs?

[error] PHP Fatal error: Call to undefined function __() in ../wp-admin/includes/file.php on line 11, referer: http://domain.com/wp-admin/setup-config.php?step=1

What worked for me is to re-upload the wp-config.php as it turned out to be corrupt due to FTP upload.

[svn][solved] eSVN commit fails

ramon fincken — Fri, 27 May 11 10:46:31 +0200

If you use eSVN and recieve this error upon committing:

Code:

svn: Commit failed (details follow):
svn: Can't get username or password
error (1)

Goto
file > options > others
and re-type your username and password

I prefer RapidSVN but it does not work on Centos when using the svn:// protocol.

[solved][matlab] Compiler Runtime in commandline fails to start or not found

ramon fincken — Thu, 26 May 11 11:08:27 +0200

Problem: I have installed the Matlab Compiler Runtime but it fails to start.
My application would run in Eclipse but not commandline or Tomcat servlet.

Solution for Redhat/CentOS systems lies in the LD_LIBRARY_PATH

How to set the LD_LIBRARY_PATH ?
I presume the Compiler runtime is installed in: /opt/MATLAB/MATLAB_Compiler_Runtime/v714

CREATE FILE java.sh in etc/profile.d/
FILE CONTENTS

Code:

export LD_LIBRARY_PATH=/opt/MATLAB/MATLAB_Compiler_Runtime/v714
#export MCRROOT=/opt/MATLAB/MATLAB_Compiler_Runtime/v714

export LD_LIBRARY_PATH=/opt/MATLAB/MATLAB_Compiler_Runtime/v714/runtime/glnxa64:/opt/MATLAB/MATLAB_Compiler_Runtime/v714/bin/glnxa64:/opt/MATLAB/MATLAB_Compiler_Runtime/v714/sys/os/glnxa64:/opt/MATLAB/MATLAB_Compiler_Runtime/v714/sys/java/jre/glnxa64/jre/lib/amd64/native_threads:/opt/MATLAB/MATLAB_Compiler_Runtime/v714/sys/java/jre/glnxa64/jre/lib/amd64/server:/opt/MATLAB/MATLAB_Compiler_Runtime/v714/sys/java/jre/glnxa64/jre/lib/amd64:
export XAPPLRESDIR=/opt/MATLAB/MATLAB_Compiler_Runtime/v714/X11/app-defaults

Now reboot.

Test with commandline:
echo $LD_LIBRAY_PATH
it should print your lines on screen.

Keep table header on top, like split in excel or calc. Scroll the rest.

ramon fincken — Thu, 05 May 11 13:06:20 +0200

Looking for a solution for this I found this great resource:
http://imar.spaanjaars.com/357/a-scroll...xed-header

This works with 2 tables, setting the second as overflow

Code:

overflow: auto;height: 100px; width: 320px;

Works great in my tested browsers (FF, Chrome and IE)

Wake on Lan

ramon fincken — Sun, 19 Dec 10 13:08:39 +0100

If your pc/server supports wake on lan and you like a GUI based approach to simply (with 1 click) power your computer .. take a look at gWakeOnLan.

Really easy, just enter the hostname and its MAC and you are ready to go!
