This is a processor emulator (MCF68k), so I can't just scp the file to the server and run from there.
I can send input like this:
`telnet host.name < input.file`
Which will successfully transmit the data to the server and run the commands stored that I want.
However, I need the telnet session to stay interactive (not terminate).

e.Cancel = (MessageBox.Show("Are You Sure You Want To Exit?", "Backup Data", MessageBoxButtons.YesNo) = DialogResult.No)

Upon form minimize e.CloseReason = 0 (Tested with MessageBox popups). So e.Cancel then equals True but the program closes itself down anyway!

I am not sure whats causing it and how to overcome it. I have a feeling that bundle is not able to detect the gems I have already installed.
I also tried out the following command: bundle exec rake db:create. It says it could not find the gem , although I have already installed it. The error I get is given below:
mohnish@pc146724-desktop:~/Diaspora/diaspora$ bundle exec rake db:create
Could not find gem 'em-websocket (>= 0, runtime)' in any of the gem sources listed in your Gemfile.

===
I am trying to set up Diaspora on my machine. I am using the following installation URL:
https://github.com/diaspora/diaspora/wiki/Installing-and-Running-Diaspora
I am trying to get the bundle install command to work for me behind a proxy( I am currently at work, thus behind a proxy ).
I have manually installed the gems( I had no choice on it; at that time), required for my app. I am facing the following error on this regard.

More specifically what I am looking for is a HL7 engine that runs on *NIX and can insert data from a HL7 v2.X message into a MySQL database. The data that is inserted will be data taken out of arbitrary fields so it needs to do parsing.
I tried using Mirth, but it's ability to make any seemingly simple task overly complex and the extreme slowness of it's client interface/response times has made us very gun shy on it. When I state a simple task I mean like sending back a custom ACK message based upon a few rules forces me to write 100 lines of javascript and after that still getting horrible response times.
I loved Iguana and wanted to use it, but they quoted us between $12k and $15k for a single instance of it on a single server. It was a good piece of software but not THAT good to justify a price tag like that as well as that is well beyond what my customer is willing to pay for a single piece of software that drives a small part of their business.
Does anybody have any recommendations for open source and/or proprietary software that will meet these needs?

For instance, a row contains :
call endpoint server (endpoint_name)
call endpoint status (sip_disconnect_reason)
call destination (destination)
call completed (duration) [duration >0 is completed]
call account group (account_group)
It's pretty easy to run SQL reports against the data, i.e.
select count(*), endpoint_name from calls where duration>0 group by endpoint_name
select count(*),destination from calls where blah group by destination
I've been calling this filtering or breakdown reports (I get the number of calls per carrier, etc.).
Add another breakdown, and you've got two breakdowns, a la
select count(*), endpoint_name, sip_disconnect_reason from calls where duration=0 group by endpoint_name, sip_disconnect_reason
Of course, if you keep adding breakdowns, you end up making super-large reports and slicing your data so thin that you can't extract any trends from it.
So my question is this :
Is there a name for this sort of method of report writing? (I've heard words like squares, slicing and breakdown reports applied to them) --- I'm looking for a Python/Reporting toolkit that I can use to make these easier to generate for my end users.
aside : Are there other ways of representing transactional data that might be useful rather than the above method?

that gives an example (above) code for iPhone but I have no idea how I would go about implementing this on android. Could any of the Math gods out there please help me out with how I would go about implementing this in Android Java.
Is it possible using the native draw APIs, would I have to use openGL? Could I mimik the behaviour somehow?
Any help would be appreciated. Thanks.

I keep running into a problem where the opacity of the image is also applied to the ribbon. In the image you can see when I hover the 1st image the ribbon appears but is also getting the opacity. see link for image http://img.photobucket.com/albums/v513/Tearyguitarist/example.png
Here's the css i'm using
#tracks-content .enrolled a:hover > .ribbon{
visiblity:visible;
}
#tracks-content .enrolled a:hover span img{
outline: solid 1px #40a304;
opacity:0.5;
}
Any suggestions? I can't use any position absolutes since the whole page is php driven and could have 1 or 10 tracks so the content has to be dynamic and reuseable.

<span><img src="images/pic-track2.png" /></span></a>
<h3>Track title 2</h3>
<span>Track description here. Lorem ipsum dolor sit amet con sectetuer adipiscing elit.</span>
</div>
</div>
So if I hover over the image for say track1.png then I want track1.png to dim to 70% and I want the visibility for ribbon.png to change from hidden to visible. I keep running into a problem where the opacity of the image is also applied to the ribbon. In the image you can see when I hover the 1st image the ribbon appears but is also getting the opacity. see link for image http://img.photobucket.com/albums/v513/Tearyguitarist/example.png
Here's the css i'm using
#tracks-content .enrolled a:hover > .ribbon{
visiblity:visible;
}
#tracks-content .enrolled a:hover span img{
outline: solid 1px #40a304;
opacity:0.5;
}
Any suggestions? I can't use any position absolutes since the whole page is php driven and could have 1 or 10 tracks so the content has to be dynamic and reuseable.

Recently the mail server went down, and my php mail script hung when the submit button was clicked. The user tried one more time, and again the page just hung. Later when the mail server came back up, it sent out multiple copies of the mail.
My question is, is there an easy way to put some sort of timeout on the script, so that if either a set period of time passes and the mail server has not acknowledged the request, or alternatively, if the number of unsuccessful attempts has exceeded a preset number, then the script will stop attempting to send the mail?
My script:
// try to send email
if (mail($to,$subject,$msg,$headers)) {
header('Location: complete.php');
} else
{
header('Location: incomplete.php');
}
Thanks for any advice you may be able to give,

We set up part of our configuration based on the path that the application is launched from, and we really want that configuration to use mapped network drive paths instead of the UNC path to the resource.
What we've found is that when we launch our application without UAC elevation, we are able to get the directory that the application launched from using
GetModuleFileName(NULL, buf, sizeof(buf));
But when we launch elevated (which we actually need to do), the buffer returned gives us a UNC based path instead of a drive letter based path.
Note that we always launch from Windows Explorer by navigating into the folder tree of the mapped drive letter.
Does anyone have any suggestions on how to get the drive letter based path of the EXE from a process that is running elevated?

2. If i use {{ form.instance.id }} to output an id while iterating through the formset, it prints out ok. However, if I do a {% url summary form.instance.id %} I keep getting an error regarding no NoReverseMatch with arguments (None,). It seems like when using form.instance.id in a template tag, it doesn't work. Is that true? If so, how do i circumvent it?

I'm building a search form where I need to provide a list of directories to a user so they can select which one(s) to search against. I'm trying to figure out how to get the selected values of a collection_select to remain after the form is submitted.
Say the user selected 3 directories from the collection_select, the id's of those directories would look like this in the params:
directory: !map:HashWithIndifferentAccess
id:
- "2"
- "4"
- "6"
I know that you can manually specify multiple selected items:
<%= collection_select :directory, :id, @directories, :id, :name,
{:selected => [2,4,6]}, {:size => 5, :multiple => true} %>
I've also played around a bit and was able to us "to_i" against a single value in the params hash:
<%= collection_select :directory, :id, @directories, :id, :name,
{:selected => params[:directory][:id][0].to_i}, {:size => 5, :multiple => true} %>
What I can't figure out is how to use all of the values of the :directory params at the same time so what the user selected remains after the form is submitted. Thanks for any help.

If the process is successful, it should return true, otherwise it should return false.
File curFile = null;
// Open a file and set curFile to this file
openFile(curFile);
bool openFile(File file) {
// Ask the user for the file to open
File tempFile = getFileFromUserInput()
// If the file exists, set file and (thus curFile) to tempFile and return true
if (tempFile.exists()) {
file = tempFile;
return true;
} else {
return false;
}
}
The problem is that it doesn't set curFile = tempFile. I think the reason for this is that although curFile is an object and is passed by reference, I'm not modifying this object in the function, I'm putting a new object in the variable. But I'm still not sure if this is the reason why it's not working. getFileFromUserInput() is actually a Swing method FileChooser.getSelectedFile(), in case that's relevant.
One fix is to return the file object instead of a bool. But that would cause curFile to be written over by the return value even when it shouldn't, such as when the file doesn't exist. There are some fixes for this, like returning null if it's an invalid file and saving the old file in a temporary variable in case null is returned, but that's ugly.
The other method is to return both the bool and File wrapped in an object, but that's even uglier.
So am I stuck with method one, or is there a nice way to do this? | java | swing | file | reference | null | null | open | File object not being modified by function

Thus, the capacity is stored as a basis for the capacity and a repeat frequency. We then allow booking into the capacity.
Capacity is stored for unique things.
Capacity for a single unique thing may occur on multiple repeat frequencies. We call these sessions.
For example, "Understanding Web Security" might run the first Monday of the month and every other month on the first Wednesday.
A given unique thing may clash with another unique thing. So "Understanding Web Security" can clash with "Basic HTML". But two sets of capacity for "Understanding Web Security" can not clash with each other.
i.e. setting up "Understanding Web Security" to run the first Monday of the month in session 1 and to run every other Monday in session 2 would be invalid.
Repeat frequencies are pretty much as-per-outlook. The problem is, with no end date, and with certain frequencies, you can EVENTUALLY get a clash, but it might be in years time.

I want to make an online web game as complex as farmville etc.. What language is the best choice for the purpose of this job?. I looked a bit and I think Java and Flex are suitable.
Which one Java or Flex? | 4 |

So to make things **as simple as possible** to the developers using it **in many coming future projects** to make use of this library I had in mind them defining an enum with roles, simple example, the role sysadmin:
// Not a project specific class, but Auth is intended to be part of the library
class Auth {
public static enum AUTH_ROLE {
sysadmin( new Rule(AdminController.class, "*") );
// ======================================================================================================================================
// --------------------------------------------------------------------------------------------------------------------------------------
// ======================================================================================================================================
private String name;
AUTH_ROLE() {
name = this.name();
Roles.add( name );
}
AUTH_ROLE(String name) {
this.name = name;
Roles.add( name );
}
AUTH_ROLE(Rule rule) {
name = this.name();
Roles.add( name, rule );
}
AUTH_ROLE(String name, Rule rule) {
this.name = name;
Roles.add( name, rule );
}
public String getName() {
return name;
}
}

String[] usersRoles = getLoggedInUsersRoles();
for ( String userRole : usersRoles ) {
if ( role.getName().equals(userRole) )
return true;
}
return false;
}
}
Now, as you can see, the **enum AUTH_ROLE** is **currently** **defined** in what is **supposed** to be a **non project** specific class, **but the Auth class** is supposed to be part of the library that is to **be used by many projects**.
The problem is that with the current design, I am forced to also define the **roles and their rules** in that same class, Auth, in order to define the method hasRole ( AUTH_ROLE ...) ...
What I would like to do, is to have this enum with all the current logic in it defined **ONCE** for **ALL PROJECTS** and allow for the developers in new projects to be able to **simply** just define the roles and their rules.
The problem I believe exists, is that you cannot extend an enum in Java, so all that in the enum logic ( although simple, not the point! ) actually has to be repeated for each new project and possibly implement and interface provided in the library.
If it were possible to extend, then a new enum would have been able to simply define those roles, that is :
public enum AUTH_ROLE extends authlibrary.Auth.AUTH_ROLE {
sysadmin( new Rule(AdminController.class, "*") );
}
The **other option**, as I just mentioned, is to **define an interface** for the enum to implement, although as you can understand **we end up** with **an implementation for each new project**, be it as simple as copy and paste.
I am not interested **in converting stuff to string or number** back and forth before calling the method and what not...
This question is **not so much** about how **you can circumvent** **the limitations** of the language, but merely to agree/accept that his is a limitation that would otherwise have resulted in cleaner code.
So, does anyone agree with that in this particular case, extending/including another enum would have been benefitial that would have resulted in less code?

Is there a solution to get all items of the view without the pager and apply the pager, when the view is rendered ? Any other solution would suit though. I am using Views 3

maybe one application is registered with two icons, one is for main process, one is to do short-cut process.
is that possible?

Recently however I've been reading a lot about "the future" of web development, RIAs, web 2.0 etc, and it appears the whole Flash/Flex/ActionScript frame work's main competition will be the HTML/CSS/JS stack (or "HTML 5").
So obviously I don't want to take the time to learn a language (Flash/Flex/AS3) that will end up dead in a couple of years and end up having to learn another one (HTML/CSS/JS), when I could just move over now.
My main interests are fairly information rich (database orientated) web sites, with high levels of user interactivity for customisation, uploading, etc. I like the whole mobile web aspect, and would like to have the capacity to also develop for that platform, as well as mobile apps etc. I love the whole "live" aspect (like the tour de flex light up map that shows user activity), not particularly bothered by uber complex animation and obviously want things to be responsive and user friendly.
So yea, any input on this would be much appreciated, I'd just like some advice for overall direction for my personal learning and development.
Thanks!!

I tried setting the Connection,Keep-Alive http request property but that had no effect and from what I can gather, http 1.1 (which I'm pretty sure I'm using) is persistent by default.
So I think there are 2 ways I can try to address this:
1. figure out how to prevent the timeout exception from being
thrown at all
2. Have the client issue the initial request without waiting
for a response, and then ping with separate requests to check when
the server is done.

I wanted to reproduce this a trailing stars image from a timelapse set of pictures. Inspired by this:
Inspiration image (I can't "upload" images because I'm a new user click links to imgur to see these if you want to): http:/i.stack.imgur.com/tZ7zW.jpg
[The original author][1] used low resolution video frames taken with VirtualDub and combined with imageJ. I imagined I could easily reproduce this process but with a more memory-conscious approach with Python, so I could use [the original high-resolution images][2] for a better output.
My algorithm's idea is simple, merging two images at a time, and then iterating by merging the resulting image with the next image. This done some hundreds of times and properly weighing it so that every image has the same contribution to the final result.
I'm fairly new to python (and I'm no professional programmer, that'll be evident), but looking around it appears to me the Python Imaging Library is very standard, so I decided to use it (correct me if you think something else would be better).
Here's what I have so far:
#program to blend many images into one
import os,Image
files = os.listdir("./")
finalimage=Image.open("./"+files[0]) #add the first image
for i in range(1,len(files)): #note that this will skip files[0] but go all the way to the last file
currentimage=Image.open("./"+files[i])
finalimage=Image.blend(finalimage,currentimage,1/float(i+1))#alpha is 1/i+1 so when the image is a combination of i images any adition only contributes 1/i+1.
print "\r" + str(i+1) + "/" + str(len(files)) #lousy progress indicator
finalimage.save("allblended.jpg","JPEG")
This does what it's supposed to but the resulting image is dark, and if I simply try to enhance it, it's evident that information was lost due lack of depth in pixel's values. (I'm not sure what the proper term here is, color depth, color precision, pixel size).
Here's the final result using low resolution images:
http:/i.stack.imgur.com/ixppn.jpg
or one I was trying with the full 4k by 2k resolution (from another set of photos):
http:/i.stack.imgur.com/JbNWL.jpg
So, I tried to fix it by setting the image mode:
firstimage=Image.open("./"+files[0])
size = firstimage.size
finalimage=Image.new("I",size)
but apparently Image.blend does not accept that image mode.
> ValueError: image has wrong mode
Any ideas?
(I also tried making the images "less dark" by multiplying it before combining them with im.point(lambda i: i * 2) but results were just as bad)

After I get them started, the client would be able to enter new rules.
Assume that the client has good Excel skills (as an example of level of tech sophistication) but has little patience for formal languages or programming.
**Cost:** $0-$500
The resulting models will NOT be executable.
Mindmaps are very useful, but the star configuration doesn't lend itself to flowchart-type applications.
BRML is much too technical, and requires the author to break down processes into page-sized chunks.
**Example of a use case:**
- A box of widgets arrives at the client office.
The user finds the section of the model for receiving a box.
Which vendor sent the box?
What does the user do with the contents of the box?
Which features of our back-end Web app have to be used to account for the new widgets?
The app will help the user find the answers to these questions.
If the answers are not there, the user can enter new rules into the app. This process must be simple enough that the business user sees the value of the effort in the short term, not as some big investment that might pay off far in the future.
**Possible features:**
- A decision-tree-like UI that the user can follow to find out what to do in a given situation.
- A search feature that allows the user to find a rule without following the tree.
- Expand/collapse so the user can see large, detailed sections of the tree as single units.
Does such an app currently exist?
Thanks very much in advance,
