I've tried eliminating every difference I could: using the same mysql instance, for example.
The only thing I can see is that my query params seem to be encoded strangely.
Here's how they look in the development instance:
This search:
GET "/individuals?utf8=%E2%9C%93&search%5Bfirstname_like%5D=&search%5Blastname_like%5D=jones&commit=Search"
Produces these params:
Parameters: {"utf8"=>"✓", "search"=>{"firstname_like"=>"", "lastname_like"=>"jones"}, "commit"=>"Search"}
In the production instance:
GET "/individuals/?utf8=%25E2%259C%2593&search%255Bfirstname_like%255D=&search%255Blastname_like%255D=jones&commit=Search"
Produces these params:
Parameters: {"commit"=>"Search", "search%5Bfirstname_like%5D"=>"", "utf8"=>"%E2%9C%93", "search%5Blastname_like%5D"=>"jones"}
The query string seems to have an extra "25" in there.
Any idea what gives?

The client side is a simple form that has login, workspace, and simply saves them onto the database. It would have been a 5-liner in PHP!
My question really is: does this code look sane/good? I am trying to avoid using async.js for now, just because I want to get my hands dirty a little to start with.
A few notes:
* I want to check if workspace and user names are taken first, but I want to check for BOTH in case they are taken
* There is still a slight race condition here: what two users submit different usernames and same workspace names at the same time? OK it's unlikely, but one of them will end up failing (one of them will be workspace-less). How would you address it? Simply deleting the user just created? Or...?
* There is a lot of indentation here. I know that it's a known issue with node... I cannot really use "return" as a trick to interrupt execution, because it's often used in an anonymous function context. So...
* I sometimes go next("Bad error here"). I plan on writing an error handler in Connect to handle these (I will probably log things onto the database).

I have to push buffers to a WiFi connected audio output device that does not do buffering or audio timestamp arbitration on its own. If I don't send the buffers at regular periodic intervals that would match reasonably the timing of a hardware sampler device, the playback becomes corrupted and starts to stutter.
I looked at the usual suspects for doing high resolution timing first before considering the "hack" I describe below. QueryPerformanceCounter looked good until I read about buggy hardware implementations in the Harddware Abstraction Layer and the complexities of variable CPU speed stepping ruining the QPC calculations. Also, the Windows multimedia timer is only accurate to 1 millisecond making its use at high sampling rates like 44.1 kHz dubious. That's why I am considering the following:
http://stackoverflow.com/questions/644510/cpu-clock-frequency-and-thus-queryperformancecounter-wrong
As far as I know every Windows PC currently made has at least hardware support for a microphone. What I am considering doing is "piggybacking" on an existing capture device's clock. I have a DirectShow push source filter that is the true source of the audio to be sent to the WiFi audio output device. I will force the Capture Filter's sample rate to match the push source filter. Then, I will use a semaphore to lock the push source filter's FillBuffer() call until the Capture Filter's FillBuffer() call produces a buffer, thereby *riding* the Capture Filter's buffer timing.
Can I count on a user's PC having at least one Capture Device?

The solution I am thinking is to let buyer download encrypted PDF file from my web site and then I email him/her a password for him/her to open and read.
I have two concerns here:
1) How can I identify each buyer's computer after they download the article? The purpose is not to allow the same buyer to download from computer B after download from computer A and try to open the file from computer B with the same password as computer A. The goal is to limit buyers to share password with friends. Even his/her friends can download the encryped PDF file, they can not open it with the password.
2) How can I limit a buyer to copy/paste out the content of my PDF file? That is how to disable the 'select' and 'copy' menu of the PDF file? My original file is a MS Word file. When I convert Word to PDF, is there any setting to change to disable 'select' and 'copy'?
Or is there better solutions?
Thank you for your wisdom on this.

I fork it and the child executes the query and the parent waits for the child for a predetermined amount of time (in function timeout) and then kills the child. I did that part because sometimes, i am not exactly sure why, but the ssh connection stops and doesnot exit. That is there is a "ssh -oConnectTimeout=60 blah blah" in the processes list for a long and the timeout function doesnt seem to work. What am i doing wrong here? The last time this problem occured, there was an ssh in process list for 5 days and still it didnot timeout and the program had stopped because it was waiting for the child. There are those extra wait() functions because previously i was getting a lot of defunct processes a.k.a zombies. So i took the easy way out..
c = fork();
if(c==0) {
close(fd[READ]);
if (dup2(fd[WRITE],STDOUT_FILENO) != -1)
execlp("ssh", "ssh -oConnectTimeout=60", serverDetails.c_str(), NULL);

if(timeout(c) == 1){
kill(c,SIGTERM);
waitpid(c, &exitStatus, WNOHANG);

std::string::size_type von = find_first_not_of(str, splitter);
std::string::size_type bis = find_first_of(str, splitter, von);

{
result.push_back(str.substr(von, bis - von));
von = find_first_not_of(str, splitter, bis);
bis = find_first_of(str, splitter, von);
}
There are duplicated calls to `find_first_not_of` and `find_first_of` which could be eliminated by various techniques. For example, I could place the function calls inside the loop condition:
std::string::size_type von, bis = 0;
while (von = find_first_not_of(str, splitter, bis),
bis = find_first_of(str, splitter, von),
von != bis)
{
result.push_back(str.substr(von, bis - von));
}
Or I could use an endless loop from which I manually break in the middle:
std::string::size_type von, bis = 0;
for (; ;)
{
von = find_first_not_of(str, splitter, bis);
bis = find_first_of(str, splitter, von);
if (von == bis) break;
result.push_back(str.substr(von, bis - von));
}
Both ways remove the code duplication, but do they actually improve the overall quality of the code? | c++ | refactoring | code-duplication | code-quality | code-readability | 07/05/2012 17:52:59 | too localized | Duplicated code above and inside while loop

http://www.netmagazine.com/tutorials/create-page-flip-effect-html5-canvas
I've changed it somewhat, to fit my application. There is no clicking on the page to turn it - you press a button outside the canvas to make it animate. The example they provided animates smoothly, but my version leaves a trail as the page turning animation moves across the canvas. Here's an example of one of the buttons:
function page2Down(event) {
if(page != 1)
{
var canvas = document.getElementById( "pageflip-canvas" );
canvas.style.zIndex = 100;
var a = function(){
var canvas = document.getElementById( "pageflip-canvas" );
canvas.width = canvas.width;
canvas.style.zIndex = 0;
};
var b = setTimeout(a, 1100);
if(page < 1)
flips[page].dragging = true;
else
flips[page-1].dragging = true;
}
}
function page2Up( event )
{
var page_num = 1;
while(page > page_num)
{
for( var i = total_pages; i > -1; i-- ) {
if( flips[i].dragging ) {
flips[i].target = 1;
if(i>page_num)
flips[i-1].dragging = true;
page--;
}
console.log(page);
flips[i].dragging = false;
}
}
while(page < page_num)
{
for( var i = 0; i < flips.length; i++ ) {
if(page == page_num) return false;
if( flips[i].dragging ) {
flips[i].target = -1;
if(i<page_num)
flips[i+1].dragging = true;
page++;
}
console.log(page);
flips[i].dragging = false;
}
}
}
The render and drawfip functions are the same as in the example. All I changed besides what I specified already were some variables:
var BOOK_WIDTH = 2264;
var BOOK_HEIGHT = 431;
var PAGE_WIDTH = 1132;
var PAGE_HEIGHT = 426;
The trail looks pretty bad, and I need to remove it. I believe it may be related to the size of the page, but I'm not entirely sure. | html5 | animation | canvas | null | null | 02/21/2012 11:10:55 | too localized | Canvas animation is leaving trail/fragments as it moves

What I want to do is to identify whether the date part of a record is the same of with the date part of today. However, I have a datatable object and I cannot use daUsage.Select with the SQL function DATEPART.
So what I'm asking is whether there is a way to filter results from a datatable without using the select function. If this is possible how is it done? I could use LINQ but I'm pretty new to it and I feel that there must be a better way to do that.

Is it possible for me to create a mock tcp/ip connection locally on my laptop so I can make the application to connect to a specific ip and port on my laptop??
I am a noob at networking, so please execuse if the question isn't clear.
The reason I am trying to do this is, the application is listening to a specific port on a tcp/ip connection on the terminal server and I remotely send some data using VB macros to the same port. I would like to test the same locally in absence of a terminal server (just using my laptop) but when I run the application it can only connect using a tcp/ip connection.
The application is written in java and can be run locally by providing an ip address and port to connect to, so I would like to see if I can make the application connect to my laptop as a tcp/ip connection.
Any inputs are appreciated. Thanks!! | java | tcp-ip | null | null | null | null | open | Testing a TCP/IP connection locally

Is the following approach to implementing this class considered up-to-date and secure?
(1) Using AES (Rijndael) algorithm, operating in CBC mode.
(2) Specifically using the AesCryptoServiceProvider class from .net. I choose this over AesManaged because some alleged speed benefits.
(3) Randomly generating IVs for each piece of information. Prepending these IVs to the encrypted information to allow for decryption
(4) I am not using any form of SALT.
(5) I am going to use a HMAC (SHA256) to verify that information has not been tampered with.
(6) I am going to use a single Key for all encryptions. I will store this key in an encrypted file
Once again, is this a secure and viable approach to symmetric encryption? I would really appreciate sources for either affirmative or negative responses. I also hope this helps gather answers to all these questions in one place.

Unfortunately it's difficult for me to describe how i produced this result because it has happened in multiple parts of my code, and the only thing that these parts have in common is their interaction with Listbox1.
the first part of code to get this error was:
Dim sqlpage As MySqlCommand = New MySqlCommand("SELECT * FROM [" & frmMain.ListBox1.SelectedItem.value & "]", con)
then i got the same exact error for:
Private Sub ListBox1_SelectedValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedValueChanged
Try

End Try
End Sub
more specifically:
Form1.Label1.Text = ListBox1.SelectedItem
and then i got it a few more times but i think the examples above will suffice.
Since there is no "With Block Variables" in the examples above then the only other option is that its object related. Ive tried different methods of defining and redefining the object variables related to the error however the results are the same. i've asked several questions on this site hoping that i would finally find a solution and i'm willing to offer 50 reputation points to anyone that can successfully solve this problem without creating more errors.

I currently have jQuery placing a JSON call to my controller, which returns a JSON object, and then I use Javascript to build the HTML manually, which is then placed in the div.
Hang on a minute. Wouldn't it be much easier to get the controller to produce the HTML on its own (using a custom control (.ascx file)), and then just return the string to be placed in the div?
Easier, schmeasier!
My current attempt involves the following javascript:
$('#MyDiv').load("/MyController/GetList");
calling the following controller method:
public PartialViewResult GetList()
{
... create model ...
var result = PartialView("CategoryList", model);
return result;
}
Problem is, I get absolutely no response from the controller. It is called correctly (as proven by a breakpoint), but Firebug doesn't even register a call to the controller in Net view (although the call does show up the Firebug Console window, with a blank response).
What is PartialView (and PartialViewResult) used for, and what should I be doing instead of this?
Thanks in advance. | ajax | jquery | asp.net-mvc | null | null | null | open | Does PartialView do what I think it should (but doesn't)?

My professor for the course is an expert in the fundamentals of computer graphics theory and the relevant mathematics, but doesn't have any understanding of modern frameworks and libraries which are used by professionals for computer graphics. She's more of a scientist than a practitioner.
If I were to use a library to help me out with ray tracing, it would probably be good if it supported distributing the computations to a cluster of computers.

My goal is to fit a list of checkboxes into a div. I have the checkboxes sorted alphabetically, and I want the list to flow from the top of the div to the bottom and then begin again in a new column when they reach the bottom. Right now, I can do this by breaking the list into chunks of a predefined size on the server-side before feeding it into my html template. But things get messy when the list gets so long that you have to scroll. I'm hoping to force it to scroll horizontally only. This is not so easy, since I'm holding each chunk in a floating div, so white-space:nowrap doesn't seem to cut it. Currently, I'm using javascript count the number of list chunks and extend the width of an intermediary container (inside the div that serves as the viewport but containing the divs that contain the data). I want something that looks roughly like this:
__________________________
| []..... []..... []..... |
| []..... []..... []..... |
| []..... []..... |
| []..... []..... |
|__________________________|
|<|_____________|___||___|>|
So I guess I have two questions:
1. Is there a good way to vertically wrap a list?
2. Is there a good way to force horizontal scrolling when the data gets too large for the viewport? | html | javascript | css | null | null | null | open | Vertical Wrapping in HTML

But I don't want my xml to contain the second xml's header. I want it to be continuous (not like it was composed by several files).
How can I append the second xml to the first without the firsts 4 - 5 lines (the header that I'm not interested about)?
I want that because I get an error when parsing the concateneted xml with sax. (my guess is that the second one's header is the reason).
Thanks. | java | android | xml | append | concat | null | open | Apend xml content to another xml (but without the header part) on Android

So, what is faster/smaller/optimized for access a multidimensional array position?
This:
multi[3][1]; // index the value position

Since "multi" is an const array the compiler should "know" already the localization of the element position, in case of using an variable pointer pointing to that array that could take more processing time, on the other hand could be faster when searching for the item that I want to display.

I know that SSL uses a public-key, so the question (maybe stupid) is, if the client and the server exchange the key someone could read the key and convert the stream to the original message, maybe it secure the connection AFTER, but if someone get the decrypt key is pointless. No?
I was reading something regarding man in the middle attacks, so if someone listen AFTER the exchange of the key, ok...the connection is secure, but what about if someone could listen it from the beginning?

I have a question about SSL, I need to use a SSL certificate for my website because i need to manage private informations.
I know that SSL uses a public-key, so the question (maybe stupid) is, if the client and the server exchange the key someone could read the key and convert the stream to the original message, maybe it secure the connection AFTER, but if someone get the decrypt key is pointless. No?
I was reading something regarding man in the middle attacks, so if someone listen AFTER the exchange of the key, ok...the connection is secure, but what about if someone could listen it from the beginning?
Thanks for the info | 2 |

Can you think of a reason not to use it?
I came up with this convention a few months and I've been using it in a few small projects since then. So far I've been happy with. I'm about to start using it in a big project so I want to be sure I'm not missing something. | php | variables | naming-conventions | null | null | 02/13/2011 21:55:37 | not constructive | Using $CamelCase for object instances and $lower_case for everything else

Any good way to automatically install software updates while I am NOT using the machine? Something like the 3AM automatic updates on Windows -- just without the restart?

First, I want to say I am no expert on cryptography, I just know some stuff, and I took a cryptography class in University. I am very interested in this topic.
I understand that many security experts out there might get angry just by the discussion of these things, but I hope you can spare me :)
My Questions:
Would it be possible to break an RSA key, in for example 1 week of time, if the cracker have already spent **X number of years** building an **index of primes** by performing every permutation of existing prime keys up to 2^2048 ?
I understand this would take an immense amount of time to do, but it would only be done once.
Given the public key, you would be able to look up what the two primes are, and hence retrieve the private key instantly.
When I consider who might break such a code, I am primarily thinking about NSA and other Governments that might have spent years in research and have the resources and interest in doing so.
Breaking an 256 AES would then be easier, as AES keys are often generated using the RSA private key.
Would it be possible to build such an index ?
How long would that take in **permutations**, and perhaps with the **fastest computer** in the world ?
I hope we can have a nice chat about this. We are just discussion theory here.
I hope you can offer me some insight on this topic.
Thanks!
