• Animate/Ease an element to position when other elements disappear

  - by Jonathan

  Please take a look at this fiddle: http://jsfiddle.net/dhcyA/ Try clicking on a block. What I want is that when the other elements disapear, the selected block will animate/ease to his giving position instead of just jumping like it does now. Then the same animation repeats itself when clicking again on the box, but then back to place. Maybe to keep in mind: I'm using a reponsive design, which means those blocks can be vertical and horizontal after scaling the window. Any redevisions on the fiddle or suggustions would be great!

• Scroll the entire page with with UITableView that doesn't take up the entire screen

  - by KJF

  The only UITableViews I have worked with thus far are sized to fill the entire page. I'm trying to create a page in my app where I will have an image and a label on the top of the page followed by a UITableView to hold comments below it. Something like this springs to mind: http://www.inquisitr.com/wp-content/fbb.jpg My problem is if I add a UITableView below the image and label, when I scroll the tableview then only the UITableView cells scroll. Not the entire page. How would I go about making the entire page scroll so that the label and image scroll off the page and more table cells appear? Thanks.

• passing different structs to a function in c

  - by clear2k

  I have different structures that need to be filled out the same way. The only difference is that they are filled based on different data. I was wondering if it's possible to pass different structures to a certain function. What I have in mind is something like: struct stu1 { char *a; int b; }; struct stu2 { char *a; int b; }; static struct not_sure **some_func(struct not_sure *not_sure_here, original_content_list) { // do something and return passed struct for(i=0; i<size_of_original_content_list; i++){ //fill out passed structure } return the_struct; } int main(int argc, char *argv[]) { return_struct1 = some_func(stu1); return_struct2 = some_func(stu2); // do something separate with each return struct... } Any comments will be appreciate it.

• Will Haskell be a good choice for my task?

  - by Narzanka

  I'm starting a new project and don't know which language to use. My 'must have' requirements are: Be able to run on Windows/LinuxMacOs natively (native executable) - user should be able to just run the exe (when on Windows for example) and see the results. No runtimes/interpreters (no jvm, clr, etc) - one file download should be enough to run the application. Full unicode support. Be able to manipulate OS threads (create them, run multiple tasks in parallel on multi-core CPUs, etc). Be reasonably fast (Python level performance and better). To have some kind of standard library that does low-level, mundane tasks. Not very niche and have some community behind it to be able to ask questions. My 'nice to have' requirements are: Language should be functional It should have good string manipulation capabilities (not necessarily regex) Not extremely hard to learn I'm thinking about Haskell now but keeping in mind OCaml as well. Please advice if my choice is correct.

• Problem removing a dynamic form field in jquery

  - by rshivers

  I'm trying to remove a dynamic form field by click a button. It will also subtract whatever values it had from the total amount from my calculation. This is the code: function removeFormField(id) { var id = $(id).attr("name"); $('#target1').text($("#total" + id).map(function() { var currentValue = parseFloat(document.getElementById("currentTotal").value); var newValue = parseFloat($("#total" + id).text()); var newTotal = currentValue - newValue; document.getElementById("currentTotal").value = newTotal; return newTotal; }).get().join()); $(id).remove(); } Okay, it will do the subtraction portion of the code with no problem, this issue is with the last line to remove the field. If I comment out the rest of the code it will work, but not with the rest of the code. I know this is something simple, yet I can't seem to wrap my mind around it. Can someone please help?

• ColdFusion debugging output in my Ajax

  - by cf_PhillipSenn

  If I turn off "Enable Request Debugging Output", the 3rd option under the Debug Output Settings, then I no longer get debug info in my $.ajax call to a cfc with access="remote". That's good, but I'd like to keep it turned on for all my other programs and turn it off programatically for this one exception. I put <cfsetting showdebugoutput="false"> at the top of my Index.cfm, but that didn't turn off the debug output coming from the cfc. Oh wait. Never mind. I had to put the in the function rather than in Index.cfm.

• How do they read clusters/cylinders/sectors from the disk?

  - by claws

  Hello, I needed to recover the partition table I deleted accidentally. I used an application named TestDisk. Its simply mind blowing. I reads each cylinder from the disk. I've seen similar such applications which work with MBR & partitioning. I'm curious. How do they read clusters/cylinders/sectors from the disk? Is it again OS dependent? If so whats the way to for Linux & for windows?

• [C++] which is better, throw an exception or return nonzero value?

  - by xis19

  While you are doing C++ programming, you have two choices of reporting an error. I suppose many teachers would suggest you throw an exception, which is derived from std::exception. Another way, which might be more "C" style, is to return a non-zero value, as zero is "ERROR_SUCCESS". Definitively, return an exception can provide much more information of the error and recovery; while the code will bloat a little bit, and making exception-safe in your mind is a little difficult for me, at least. Other way like returning something else, will make reporting an error much easier; the defect is that managing recovery will be a possibly big problem. So folks, as good programmers, which would be your preference, not considering your boss' opinion? For me, I would like to return some nonzero values.

• iPhone to Java EE remoting

  - by Justin Simonelis

  Hi there! I was looking for some opinions on the best remote method invocation practices when developing iPhone applications that communicate with Java (java EE) servers. Many iphone applications these days typically talk to a server back end. I typically prefer to write my servers in java using some Spring libraries. So far I have not found or stuck to a definitive practice for iphone-java server communication. What are some technical solutions and libraries that you have used to implement this kind of client-server communication? One thing I always keep in mind is that I want the communication protocols to be simple so that multiple platforms can be added for example, in future adding Android and possibly Blackberry clients, that can use the same protocol to talk to the server.

• Read from socket

  - by Alberto

  I need to read from an AF_UNIX socket to a buffer using the function read from C, but I don't know the buffer size. I think the best way is to read N bytes until the read returns 0 (no more writers in the socket). Is this correct? Is there a way to guess the size of the buffer being written on the socket? I was thinking that a socket is a special file. Opening the file in binary mode and getting the size would help me in knowing the correct size to give to the buffer? I'm a very new to C, so please keep that in mind.

• Throwing special type of exception to terminate unit test

  - by trendl

  Assume I want to write a unit test to test a particular piece of functionality that is implemented within a method. If I wanted to execute the method completely, I would have to do some extra set up work (mock objects expectations etc.). Instead of doing that I use the following approach: - I set up the expectations I'm interested in verifying and then make the tested method throw a special type of exception (e.g. TerminateTestException). - Further down in the unit test I catch the exception and verify the mock object expectations. It works fine but I'm not sure it is good practice. I do not do this regularly, only in cases where it saves me time and effort. One thing that comes to mind as an argument against using this is that throwing exceptions takes long time so the tests execute slower than if I used a different approach.

• php/ssh2 script does not display the stdout to $stream

  - by kamal

  The following php script works for simple linux commands, like ps -ef , but when i use ./dstat -t -a , it seems to hang and i dont get the prompt back on my local machine. Kep in mind that all commands are executed over ssh on a remote host: <?php $target = time() . '_' . 'txt'; if($ssh = ssh2_connect('10.1.0.174', 22)) { if(ssh2_auth_password($ssh, 'root', 'kmoon77')) { //$stream = ssh2_exec($ssh, 'whoami'); $sCommand = 'dstat -a'; //$sCommand = 'ps -ef'; $stream = ssh2_exec($ssh, $sCommand); //$stream = ssh2_exec($ssh, 'pwd'); stream_set_blocking($stream, true); $data = ''; while($buffer = fread($stream, 4096)) { $data .= $buffer; } //fclose($stream); echo $data; // user } } ?>

• $.ajax + authentication + `@` in username

  - by Koning Baard XIV

  I am creating a web app which uses jQuery to authenticate: $.ajax({ url: "/session/create?format=json", type: "GET", dataType: "json", cache: false, username: $("#signin-email").val(), password: $("#signin-password").val(), success: function(data) { if(data.success) { success = true; } } }); The problem is that the code only makes the AJAX-request when the username does not include things like an @, which is required in my app. Can anyone help me with how I can do this? I do not mind changing the back-end a little bit, but requiring users to have an @-less email is not an option. Oh, my back-end is a Ruby-on-Rails app

• php/mysql question, retrieving information

  - by chance

  Hey SO, I have a question, pretty new at PHP and MySql but was curious is it possible to display only the most recent column to a table, from a database? I know it is possible to display a list of all information, or if you have just one column of information in your table to display that using the Here is my code for my basic script (just loads 1 column of information) I would like it to only print out the recent column i added to the table $con = mysql_connect ("localhost","username","password"); if (!$con) { die ('Could not connect:' . mysql_error()0; } mysql_select_db("db_name", $con); $result = mysql_query(Select column FROM table"); while($row = mysql_fetch_array($result)) { echo $row['column']; } mysql_close($con); * keep in mind, im not looking for someone to shoot me my code with it completed, though it would be handy, however just giving me the options of what I have to do, or what the script is called would be plentiful enough for my research, thanks!

• Long list of if statements in Java

  - by steve

  Hi, Sorry I can't find a question answering this, I'm almost certain someone else has raised it before. My problem is that I'm writing some system libraries to run embedded devices. I have commands which can be sent to these devices over radio broadcasts. This can only be done by text. inside the system libraries I have a thread which handles the commands which looks like this if (value.equals("A") { doCommandA() } else if (value.equals"B") { doCommandB() } else if etc. The problem is that there are a lot of commands to it will quickly spiral to something out of control. Horrible to look out, painful to debug and mind boggling to understand in a few months time.

• extended permissions

  - by melimoreno

  Hi i'm doing a fb app that update the status box(what's in your mind), i'm using set_status from facebooker .. first i have this error: set_status needs extended permission so i google it and find this: before_filter :ensure_has_status_update .. so i put it in my controller and that solves the problem, but when i try to update the status, all ways redirect me to a fb page that says: You have already granted permissions to this application. so i go to the controller comment before_filter :ensure_has_status_update and then go to my app again and it works.. so i want to do this if (has_status_update == false) ask for permision else update the status i google it for a long time but i can't find an answer..

• How can I combine multiple iPhone applications in to one application?

  - by Toret

  At the moment I have 2 completed iPhone applications. Both these applications must be contained in to one application. I can't have multiple apps on the app store and to avoid confusion among people using these apps I must have them contained to a single application that gives the user the capability to launch any application in the wrapper. How can I go about doing this. Some of the ideas that crossed my mind are: Building a Framework, or building a library. But Im not even sure if I'm heading in the right direction.

• Is there a tool that automatically saves incremental changes to files while coding?

  - by Bob.

  One of my favorite features of Google docs is the fact that it's constantly automatically saving versions of my document as I work. This means that even if I forget to save at a certain point before making a critical change there's a good chance that a save point has been created automatically. At the very least, I can return the document to a state prior to the mistaken change and continue working from that point. Is there a tool with an equivalent feature for a Ruby coder running on Mac OS (or UNIX)? For example, a tool that will do an automatic Git check-in every couple of minutes to my local repository for the files I'm working on. Maybe I'm paranoid, but this small bit of insurance could put my mind at ease during my day-to-day work.

• Network license control for a Java application

  - by user1461615

  I have been tasked with providing some form of network license control for a Java application. The app would be stored on a network drive and run from a client machine. The basic idea is that it will be able to work out how many times it is being run concurrently and prevent the N+1th user from running the software where N is the number of concurrent licenses the customer has purchased. Is this possible somehow with a Java application? I implemented a "solution" which relied on multi-cast UDP communication between the running instances of the application but this didn't work because on most networks this kind of communication is blocked by security measures. Is there a better way? I don't even mind if it requires JNI/JNA. N.B. The solution does not have to be that sophisticated or highly secure.

• [C++] Passing around objects to network packet handlers ?

  - by xeross

  Hey, I've been writing a networking server for a while now in C++ and have come to the stage to start looking for a way to properly and easily handle all packets. I am so far that I can figure out what kind of packet it is, but now I need to figure out how to get the needed data to the handler functions. I had the following in mind: Have a map of function pointers with the opcode as key and the function pointer as value Have all these functions have 2 arguments, packet and ObjectAccessor ObjectAccessor class contains various functions to fetch various items such as users and alike Perhaps pass the user's guid too so we can fetch it from the objectaccessor I'd like to know the various implementations others have come up with, so please comment on this idea and reply with your own implementations. Thanks, Xeross

• How to schedule heavy work for later display for Listviews?

  - by Pentium10

  I have a listview with 200 items. I use a custom view for each row. There is a code that takes some time to calculate, and because of this the list hangs out on scrolling and loads in slow (2-3sec). I have subclassed SimpleCursorAdapter, and using Filterable and SectionIndexer. I have in mind to show initially the name of the record, and put in a thread the calculation, and will show up later when it's done. How do I push back some work, and later update the listview to include the calculated data? This should show up on fly without user interaction.

• Read external HTML page and then find data within

  - by inthewayboy

  I'm playing around with an idea, and I'm stuck at this one part. I want to read an external HTML page and then extract the data held within two <dd> tags. I've been using file_get_contents with good results, but I'm at a loss as to how to accomplish that last part. The two tags I want to extract the value from are always enclosed within a particular <div>, was wondering if that might help? In my mind it reads the entire html file into a string, then dumps all the data up until this one particular <div>, and dumps all the data after the closing </div>. Is that possible? I think this needs regex syntax which I've never used yet. So any tips, links, or examples would be great! I can provide more info as necessary.
