So it is something like input1=>phase1=>outpu1=>phase2=>output2=>phase3=>final_output
I want to write a java application in which the users can extend any phase to implement their own functionality.
for e.g: lets say that phase1 sorts the given input. I want to let my app users create custom class which will replace the functionality of phase1. they may want to do counting instead of sorting.
Any ideas on how to do this? plugin architecture? Any examples of frameworks which work in similar way? Where to start? | java | architecture | customization | extends | plugin-architecture | 06/21/2012 13:10:31 | not constructive | My own Java application which can be customized

[1]: http://msdn.microsoft.com/en-us/library/cc304129%28VS.85%29.aspx
It works when I set the values which are more than or equal to 2. But when I set the values to 1, there are still probably 2 concurrent connections. Is it possible for me to make it only one connection at the same time for IE8?
Thanks so much!

I have a for-loop in a Javascript funtion that looks something like this:

for(i = 0; i < arrayCount; i++){
jsArray[i] = <%= myBeanArrayList.get(count) %>;

The count variable doesn't increment even if I use <% count = count + 1 %>. I don't understand why that peice of code doesn't do as I want inside the loop. Does anyone have any suggestions on how I can increment the count for the JSP Bean?

At the moment, I have the connection string used by the templates embedded an a template include file in the class library. Is there a convenient way to have the template grab the connection string from the main project (WAP)'s web.config without having to include a physical path? Or is there a better way to approach this?
**Edit**
I've also considered creating a SQL CLR assembly which returns a table-valued function containing the enum contents (which would then be defined in C#, not in the database), but I'm not sure what the performance hit would be. Whether or not it's significant will obviously be application-dependent but I'd hate to charge down a crappy path if it's a know best-avoid-this approach.

Ideally, it should have support for several frames of similar drawings with little variation between them and, most importantly, changes could be propagated to all frames.
I currently use yEd to draw graphs, but copy/paste between different images has several issues, for instance, if I change the color of a node after having created several copies, I have to change it in each image separately.
I once used (for a very brief time) Macromedia Flash and I believe it would be quite nice to try with it, but it costs simply too much and is overkill.
DOT is quite nice but I couldn't find a graphical interface with quick feedback to ease the task. It wouldn't bother me if the tool required some programming, but the text-to-image conversion should be almost real-time.
Last time I tried Dia and Visio both didn't seem to have what I want, but maybe I missed it...

What I want to do is ...
I'm writing unit tests where I set up expected input & output messages at compile time. Later at run time, I want to do some checks when each output is received or input has been processed, so I added a parameter for a callback function.
That's working fine and I could leave it & move on, but ... I am just curious ...
sometimes a function is overkill and I just need a single comparison; sometime a small block of code would do. Perhaps I could just evaluate these to a zero/non-zero value at run time? But how to pass as a parameter?
At the moment my function has the following signature
void AddExpectedCommand(E_peripheralType peripheral,
communicationBlock_t commandBlock,
errorMessage_t errorMessage,
void *(*DoRunTimeChecks)(E_boolean));
where the final parameter is pointer to a callback function returning boolean.
Is there any way that I could pass a code expression as a parameter instead?
Or does a function seem "cleaner"?
Thanks in advance for any help ...

where the final parameter is pointer to a callback function returning boolean.
Is there any way that I could pass a code expression as a parameter instead?
Or does a function seem "cleaner"?

It seems to accept everything in the post except for the FileBody.
The strAttachedFile in
me.addPart("videoFile", new FileBody(new File(strAttachedFile)));
is the directory path to a video on the phone.
I use logcat to make sure the path is correct.
When i run script to upload, this is what log cat `returns: INFO/TestPathkkkkkk(21987): /mnt/sdcard/DCIM/100MEDIA/VIDEO0111.3gp`
But on the PHP script side it only shows the video name and not the full directory.
Anyways long story short, I was wondering if there is anyway to httppost to php script without using Multipartentity?
Thanks, in advance.

We have SQL Server 2008 Enterprise.
We have a valid backup procedure but I want to have a document that will describes all the steps.
Do you know/encountered a link/s that specifies all the necessarily steps to create a duplicate SQL Server based on an old server?
I need that it will be identical in all its components of the instance (I'm not talking about the installation of the Server / cluster)
I'm talking about components such as:
- Database
- Jobs
- Server configuration attributes (sp_configure)
- Security objects - Logins, Users, Permission, Credentials and Audit configuration
- Other objects such as Linked servers, Mail profiles
- Replication information
The reason I'm looking for such thing is becuase:
1. I don't want to strat with nothing. I guess that the basic is written somewhere online.
2. It's a good way to verify that I haven't forggoten anything.

Hi Guys!!!<br>
I am stuck with a c++ program which is an assignment.<br> Please help me out.
Please suggest an approach if possible,<br> <em>thanks in advance</em>
code:
Given two vessels, one of which can accommodate a liters of water and the other which can
accommodate b liters of water, determine the number of steps required to obtain exactly c
liters of water in one of the vessels.
At the beginning both vessels are empty. The following operations are counted as 'steps':
• emptying a vessel,
• filling a vessel,
• pouring water from one vessel to the other, without spilling, until one of the vessels is
either full or empty.
Input
An integer t, 1<=t<=100, denoting the number of test cases, followed by t sets of input data,
each consisting of three positive integers a (the number of liters the first container can hold),
b (the number of liters the second container can hold), and c (the final amount of liters of
water one vessel should contain), not larger than 40000, given in separate lines.

The two jobs are a web developer internship in SF from the past summer, and a CS TA on campus. The TA job I have been working for almost two years, so it is "present", does that mean I have to put this position ahead of my summer intern in my resume? I really want to put my intern first because I have more highlights and it's really more relavent.
Another question, I have these sections, education, work experience, projects, skills, positioning in the sequence I list here. But I'm not sure if I should put skills section at the top of my resume or bottom.

Some of our requirements:
- We host everything ourselves
- Bandwidth is not an issue (we got good backings)
- Commodity hardware (no expensive NAS, SANs)
- Support large files
- Prefer not to use Flash Media Server
The situation here is a little bit different than what some of you guys might have experienced before. The cost of a professional system-admin and developers are way much cheaper than signing a contract with hardware or software vendors in storage solutions area. The way we scale is by buying cheap commodity hardware and (probably) build the infrastructure ourselves using varieties of open source software.
We're looking at a varieties of distributed file systems for storage such as MogileFS, GlusterFS, HDFS and it looks like HDFS might be the front runner.
Please share your experience if you've built something similar before.

The examples I have seen so far were always for c strings.
My real program, which I will not even try to show here, uses sub matches but I could not
make them work, so I tried to modify a very simple working example but it does not work either. I use Visual Studio 2010 Ultimate.
The original - working - code:
const char *first = "abcd";
const char *last = first + strlen(first);
std::cmatch mr;
std::regex rx("abc");
std::regex_constants::match_flag_type fl = std::regex_constants::match_default;

<< regex_search(first, last, mr, rx) << std::endl;

std::cout << "search(\"xabcd\", \"abc\") == " << std::boolalpha
<< regex_search("xabcd", mr, rx) << std::endl;
std::cout << " matched: \"" << mr.str() << "\"" << std::endl;
The modified code:
const string first = "abcd"; // char * => string

std::regex rx(string("abc"));

<< regex_search(first, mr, rx) << std::endl;
std::cout << " matched: \"" << mr.str() << "\"" << std::endl;

// mr[0] = {3, matched:true, first="abcd", second="d",...}
std::cout << "search(\"xabcd\", \"abc\") == " << std::boolalpha
<< regex_search(string("xabcd"), mr, rx) << std::endl;
// but the following line gives the error
// "Debug assertion failed"
// Expression: string iterators incompatible
std::cout << " matched: \"" << mr.str() << "\"" << std::endl;

Is there a way to predict these errors or test if they might occur?
In this case the boot process stopped before sshd (or similar) was started and
on the console the message press control-D to proceed.
Is there a way to force the boot up to ignore these errors? | linux | boot | reboot | null | null | 07/09/2012 00:34:13 | off topic | failsafe reboot after remote linux server upgrade

I would like to obtain an IP address from this file and append a colon 0 (:0) on the end, so as to set the DISPLAY environment variable. When I try to do so, I get strange results.
Here is the script:
#!/bin/bash
LOCAL_HOST=`grep IPv4 /mnt/hgfs/share/localip | awk 'NR ==1 {printf "%s\n", $14 }'`
# for some reason, it overwrites the string from the beginning
COLON_ZERO=':0'
export DISPLAY=${LOCAL_HOST}${COLON_ZERO}
echo $DISPLAY
# This obviously works, but doesnt have the COLON_ZERO on the end
echo "export DISPLAY="$LOCAL_HOST
And here is the output of running this script:
# ./display.sh
:09.107.26.25
export DISPLAY=159.107.26.25
# bash --version
GNU bash, version 3.2.48(1)-release (x86_64-pc-linux-gnu)
Copyright (C) 2007 Free Software Foundation, Inc.
And just in case its necessary, here is the result of the grep from the file used in the script:
# grep IPv4 /mnt/hgfs/share/localip
IPv4 Address. . . . . . . . . . . : 159.107.26.25
IPv4 Address. . . . . . . . . . . : 192.168.223.1
IPv4 Address. . . . . . . . . . . : 192.168.132.1
Why do I get this strange result when I append the colon zero onto the end of the IP address string? How can I change the script to get the correct result?
