Ajax: A new Approach to Web Application

http://www.adaptivepath.com/publications/essays/archives/000385.php

Quoted from above web site.

Take a look at Google Suggest. Watch the way the suggested terms update as you type, almost instantly. Now look at Google Maps. Zoom in. Use your cursor to grab the map and scroll around a bit. Again, everything happens almost instantly, with no waiting for pages to reload.

Google Suggest and Google Maps are two examples of a new approach to web applications that we at Adaptive Path have been calling Ajax. The name is shorthand for Asynchronous JavaScript + XML, and it represents a fundamental shift in what’s possible on the Web.

using inter-process lock

In Linux

A tutorial on how to use flock

http://www.ecst.csuchico.edu/~beej/guide/ipc/flock.html

Linux command: ipcs and ipcrm ACE

In ACE

ACE_OS::flock_xxx is a wrapper facility on top of flock which is fully supported in Linux 2.4.

In windows 2003 server, it is not working well. Instead, we can use ACE_Process_Mutex

Note:

Essentially, the initialization of a lock is to open a file. In order to avoid file handler leaking, we need to call flock_destroy() or delete the ACE_Process_Mutex object.

If we fail to get the lock by trywrlock(), we call flock_destroy() to release the file handler created in flock_init(), but we have to use “0” to indicate that we do not want to unlink the file; else it will break the lock if other processes depends on this file.

In Linux, the process_mutex is implemented by semaphore. Semaphore is a system wide resource. It will lead to serious situation if there is a leak on it. You can use ipcs or ipcrm to dump and control semaphore.

While flock will be released once the process is gone, therefore, it is much safer in case the process could be possibly killed abnormally.

Here is the code snippet.

#if !defined(WIN32) //in Linux

void SymLoggerControl::finiLog()

{

ACE_OS::flock_destroy(&m_flock);

}

int SymLoggerControl::initAutoIndex(const SymString &filename, const SymString &i_name)

{

const int MAX_TRY = 1000;

int iret = -1;

if (i_name != "sim")

return iret;

SymString fstr;

SymString lockName;

for (int i=1; i<MAX_TRY;i++)

{

fstr = filename + "." + intToString(i) + ".log";

lockName = "."+i_name + intToString(fstr.hash());

if (ACE_OS::flock_init(&m_flock,O_CREAT|O_RDWR,lockName.c_str(),0600)!=0)

continue;

if (ACE_OS::flock_trywrlock(&m_flock)!=0)

{

//we use 0 to indicate that the destroy can not unlink the file

//else it breaks the lock on other processes

ACE_OS::flock_destroy(&m_flock,0);

continue;

}

setAutoIndex(i);

return iret;

}

setAutoIndex(0);

return -1;

}

#else

void SymLoggerControl::finiLog()

{

if (m_logfileLock)

m_logfileLock->release();

}

int SymLoggerControl::initAutoIndex(const SymString &filename, const SymString &i_name)

{

if (i_name != "sim")

return 0;

const int MAX_TRY = 1000;

SymString lockName;

SymString fstr;

for (int i=1; i< MAX_TRY;i++)

{

fstr = filename + "." + intToString(i) + ".log";

lockName = i_name + intToString(fstr.hash());

// try to get the lock.

ACE_NEW_RETURN(m_logfileLock, ACE_Process_Mutex(lockName.c_str()), -1);

if (m_logfileLock->tryacquire() != 0)

{

//avoid memory leak

SAFE_DELETE(m_logfileLock);

continue;

}

setAutoIndex(i);

return 0;

}

setAutoIndex(0);

return -1;

}

generic wrapper for logger

Ggeneralized the service wrapper script that does stdout+err redirection to a file

It's literally 3-4 dead simple lines of code

 

ServiceWrapper (must be made executable with something like chmod a+x ServiceWrapper)

 

#!/bin/bash -f
# -f: do not source .bashrc (for speed)
# Alain Andrieux, Platform

 

# Wrapper script for stdout/err redirection, service troubleshooting, etc...

# To use this wrapper instead of the service executable:
# 1) specify the startCmd of the service in the application profile as such:
# startCmd="${SOAM_DEPLOY_DIR}/ServiceWrapper MyServiceExecutable"
# 2) package this file along with the service executable
#
# To stop using this script, simply change the
# service startCmd in the app profile back to:
# startCmd="${SOAM_DEPLOY_DIR}/MyServiceExecutable"

 

serviceExeName=$1

shift

outputFile=$SOAM_HOME/work/$serviceExeName.$HOSTNAME.log

# The service deployment dir is in the PATH, so no need for absolute path
$serviceExeName $* >> $outputFile 2>&1

 

# Note:
# If the service executable name is ommitted or incorrect, the following kind of# error message will appear in the SIM log:
# 2006-06-14 16:57:36.399 GMT ERROR [22435:35433392] sim.backend.ServiceBroker - [-905929660] (1, 10, 40004)  SimBasicSiAdaptor.cpp:461   Domain <Application>: Failed to start the service instance, service name /home/sc49285/soam/deploy/PLGridService 1.0.v8/ServiceWrapper. The service startCmd command specified in the Application Profile terminated unexpectedly with exit code: 0 State:Exit. Check your Application Profile, whether the services dependent libraries can load and your service code.

how to add citation reference in word

An extremely useful skill but can not find it anywhere.

 

Here is my finding.

 

1. Create a list of referenced papers, and using “[ index ] “

 

Select them, click [Format] à [bullet and numbering…] à [customize] à [number format] to add [ ]

 

2.  In the document, insert a citation

 

Click [Insert] à [ reference ] à [ cross –reference ], in “Reference Type” choose Numbered item, then in “For which numbered item”, it will show the newly added list. Choose one from the list (check Insert as hyperlink)
