  • request payload versus query string parameters

    - by Sarah Sides
    I am absolutely in the dark when it comes to this request payload that I'm seeing in my Chrome browser. A Query string will have a variable attached like session:2g0SoEE but this payload has just one long string I'm guessing is in base64. I do understand that the request payload can have whatever, but how do I use it? Can I do a post with jquery and send this request payload? For example: $.post(url, {variable: "variable"}, function(data){}); When this posts it will send &variable=variable this will be found as query string parameter in the headers sent in chrome. In this game I'm playing I see another piece of info being sending in the header called a payload request. I'm a confused as to how this is read, used, made, how I can reduplicate this? Here is something similar: Chrome is caching an HTTP PUT request and How to retrieve Request Payload

  • real time updates for new page events

    - by Ben Ford
    I know there's a few questions knocking around on this topic but none quite the same. I'm currently searching by location for all the pages relating to a particular geographic location and caching their events in a database. The problem being I have to currently loop through all the pages i'm watching frequently to check for updates. At the moment the 10,000 Pages I'm keeping track of takes a good while to update. It would be much neater (and nicer to fb) to be notified instead of polling. Does anyone know of a more efficient to do this? Thanks Ben

  • Ruby: change each value in a hash with something like #collect for arrays?

    - by Adam Nonymous
    Hi! I'd like to replace each value in a hash with value.some_method. For example in a simple hash {"a" = "b", "c" = "d"} every value should be .upcase-d so it looks like {"a" = "B", "c" = "D"}. I tried #collect and #map but always just get arrays back. Is there an 'elegant' way to do this? Thanks in advance, Adam Nonymous UPDATE: Damn, I forgot: The hash is in an instance variable which should not be changed. I need a new hash with the changed values, but would prefer not to define that variable explicitly and then loop over the hash filling it. Something like new_hash = hash.magic {...} ;)

  • Copy Rows in a One to Many with LINQ (2 SQL)

    - by Refracted Paladin
    I have a table that stores a bunch of diagnosis for a single plan. When the users create a new plan I need to copy over all existing diagnosis's as well. I had thought to try the below but this is obviously not correct. I am guessing that I will need to loop through my oldDiagnosis part, but how? Thanks! My Attempt so far... public static void CopyPlanDiagnosis(int newPlanID, int oldPlanID) { using (var context = McpDataContext.Create()) { var oldDiagnosis = from planDiagnosi in context.tblPlanDiagnosis where planDiagnosi.PlanID == oldPlanID select planDiagnosi; var newDiagnosis = new tblPlanDiagnosi { PlanID = newPlanID, DiagnosisCueID = oldDiagnosis.DiagnosisCueID, DiagnosisOther = oldDiagnosis.DiagnosisOther, AdditionalInfo = oldDiagnosis.AdditionalInfo, rowguid = Guid.NewGuid() }; context.tblPlanDiagnosis.InsertOnSubmit(newDiagnosis); context.SubmitChanges(); } }

  • Python: Trying to get index of an intersection

    - by user1620716
    I have the following line of code: for i in [i for i,x in enumerate(catdate) if x == set(NNSRCfile['datetimenew']).intersection(catdate)]: print i I am trying to find the index of the intersection for the two components above. Both are lengthy lists that have several commonalities. The intersection part works perfectly; however, the for loop seems to output nothing. (ie: there is nothing that is printed). Python outputs no error, and when I run the code in IPython, I notice that i is equivalent to to the very last element in the list "catdate", instead of listing the indices of "catdate" that are equivalent to the intersection values. Any help is greatly appreciated!

  • OpenGL extensions available on different Android devices

    - by MH114
    I'm in the process of writing an OpenGL ES powered framework for my next Android game(s). Currently I'm supporting three different techniques of drawing sprites: the basic way: using vertex arrays (slow) using vertex-buffer-objects (VBOs) (faster) using the draw_texture extension (fastest, but only for basic sprites, i.e. no transforming) Vertex arrays are supported in OpenGL ES 1.0 and thus in every Android-device. I'm guessing most (if not all) of the current devices also support VBOs and draw_texture. Instead of guessing, I'd like to know the extensions supported by different devices. If majority of devices support VBOs, I could simplify my code and focus only on VBOs + draw_texture. It'd be helpful to know what different devices support, so if you have an Android-device, do report the extensions list please. :) String extensions = gl.glGetString(GL10.GL_EXTENSIONS); I've got a HTC Hero, so I can share those extensions next.

  • Synchronisation construct inside pragma for

    - by Sayan Ghosh
    Hi, I have a program block like: for (iIndex1=0; iIndex1 < iSize; iIndex1++) { for (iIndex2=iIndex1+1; iIndex2 < iSize; iIndex2++) { iCount++; fDist =(*this)[iIndex1].distance( (*this)[iIndex2] ); m_oPDF.addPairDistance( fDist ); if ((bShowProgress) && (iCount % 1000000 == 0)) xyz_exception::ui()->progress( iCount, (size()-1)*((size()-1))/2 ); } } } } I have tried parallelising the inner and outer loop and by putting iCount in a critical region. What would be the best approach to parallelise this? If I wrap iCount with omp single or omp atomic then the code gives an error and I figured out that would be invalid inside omp for. I guess I am adding many extraneous stuffs to paralellise this. Need some advice... Thanks, Sayan

  • jQuery slide up/down on hover bug

    - by Eirik Lillebo
    Hi! I have one large div with one smaller div inside it. The smaller div is at first displayed as hidden. When the user hovers the mouse over the large container-div the smaller div is animated in with the show/hide-functions. So far everything works fine. However. The smaller div is animated in from the bottom - so if I let the cursor hover over the container at the very bottom, it's hovering over the animation of the smaller div while it's sliding in. So now the cursor is hovering over the smaller div instead of the larger div, and thus triggering the hide-function on the smaller div. This creates an infinite loop of show/hide calls as the smaller div slides in and out of where the cursor is pointing. Any ideas how to avoid this and not break the hovering on the container as the smaller div enters?

  • Preload *.wav with SystemSoundID?

    - by fuzzygoat
    I am playing a wav file to give a little audio feedback when a button in my UI is pressed. My question is when you first press the button there is a delay (about 1.5secs) whilst the sound file "sound.wav" is loaded and cached. Is there a way to pre-cache this file (maybe in my viewDidLoad)? I guess I could do it by just playing it a viewDidLoad, but would really need to disable the audio so it does not "beeb" each time the app starts. many thanks for and help. gary EDIT: Looks like my question is a duplicate of this post unless anyone has any new info? Maybe a way to turn the play volume down temporarily, unless the audio is cleared each time through the run loop.

  • In SQL, in what situation do we want to Index a field in a table, or 2 fields in a table at the same

    - by Jian Lin
    In SQL, it is obvious that whenever we want to do a search on millions of record, say CustomerID in a Transactios table, then we want to add an index for CustomerID. Is another situation we want to add an index to a field when we need to do inner join or outer join using that field as a criteria? Such as Inner join on t1.custumerID = t2.customerID. Then if we don't have an index on customerID on both tables, we are looking at O(n^2) because we need to loop through the 2 tables sequentially. If we have index on customerID on both tables, then it becomes O( (log n) ^ 2 ) and it is much faster. Any other situation where we want to add an index to a field in a table? What about adding index for 2 fields combined in a table. That is, one index, for 2 fields together?

  • iPhone OpenGLES textures - colour banding

    - by chicknstu
    I've got a problem with openGL on iPhone which I'm sure must have a simple solution! When I load a texture and display it, I get a lot of what I believe is called 'Colour Banding', whereby the colours, particularly on gradients, seem to get automatically 'optimized'. Just to demonstrate that this wasn't anything wrong with my own code, I downloaded the iPhone 'Crashlanding' app and replaced the background image, and as you can see in the image below (Taken from the simulator), the exact same thing happens. The image on the left is the original PNG, and on the right is it in the game. It's almost as if it's palette is being downsized to a 256 colour one. Screenshot I'm sure this is related to the format I'm saving the image as, although it doesn't just happen with PNG's, it seems to happen no matter what image format I chose. Doing my head in! If you want to recreate this, simply download the crash landing app, and replace the background. Thanks so much in advance for any help.

  • How can I add sprite image from a set of sprites which have different properties for each sprite?

    - by srikanth rongali
    In my application one player and 10 targets are there. Each target appears one after the other (from target1 to target10). It's a shooting game. If we hit the first target then second target will come. The targets have properties like name, speedOfGunDraw, probability to hit the player, speedOfFire. What should I do to make them appear one after the other with these properties. I am using CCMenuItem for the target. I am using a sprite for the player. Please give me idea to do this. Thank You.

  • Create a color generator in matplotlib

    - by Brendan
    I have a series of lines that each need to be plotted with a separate colour. Each line is actually made up of several data sets (positive, negative regions etc.) and so I'd like to be able to create a generator that will feed one colour at a time across a spectrum, for example the gist_rainbow map shown here. I have found the following works but it seems very complicated and more importantly difficult to remember, from pylab import * NUM_COLORS = 22 mp = cm.datad['gist_rainbow'] get_color = matplotlib.colors.LinearSegmentedColormap.from_list(mp, colors=['r', 'b'], N=NUM_COLORS) ... # Then in a for loop this_color = get_color(float(i)/NUM_COLORS) Moreover, it does not cover the range of colours in the gist_rainbow map, I have to redefine a map. Maybe a generator is not the best way to do this, if so what is the accepted way?

  • Dealing with dependencies between WCF services when using Castle Windsor

    - by Georgia Brown
    I have several WCF services which use castle windsor to resolve their dependencies. Now I need some of these services to talk to each other. The typical structure is service -- Business Logic -- DAL The calls to the other services need to occur at Business Logic level. What is the best approach for implementing this? Should I simply inject a service proxy into the business logic? Is this wasteful if for example, only one of two method from my service need to use this proxy? What if the services need to talk to each other? - Will castle windsor get stuck in a loop trying to resolve each services dependencies?

  • Show only Parent Forums on bbPress front page

    - by Cameron
    I want to show only the very top level forums on my front page. I have tried: <?php if ( bb_forums("depth=1") ) : ?> But that didn't work and all the forums still show up. I only want to show the very top level, so for example if I have the following forums: Main - Sub Forum 1 - Sub Forum 2 --- Sub Forum 2.1 --- Sub Forum 2.1 - Sub Forum 3 Community - Sub Forum 1 - Sub Forum 2 --- Sub Forum 2.1 --- Sub Forum 2.1 - Sub Forum 3 Only Main and Community would appear on the home page. I would seem I need to create a custom loop on the front page that will only show the very top level forums, but I need some help. Thanks.

  • Counting problem: possible sudoko tables?

    - by Sorush Rabiee
    Hi, I'm working on a sudoko solver. my method is using a game tree and explore possible permutations for each set of digits by DFS Algorithm. in order to analyzing problem, i want to know what is the count of possible valid and invalid sudoko tables? - a 9*9 table that have 9 one, 9 two, ... , 9 nine. (this isn't exact duplicate by this question) my solution is: 1- First select 9 cells for 1s: (*) 2- and like (1) for other digits (each time, 9 cells will be deleted from remaining available cells): C(81-9,9) , C(81-9*2,9) .... = 3- finally multiply the result by 9! (permutation of 123456789 in (*)) this is not equal to accepted answer of this question but problems are equivalent. what did i do wrong?

  • Generating an array of functions?

    - by Wordpressor
    I have a few PHP files filled with multiple functions. Let's call them functions1.php, functions2.php, functions3.php: function function_something( $atts ) { extract( something_atts( array( 'foo' => 'bar', 'bar' => 'foo, ), $atts ) ); return 'something'; } I'm loading these files within all_functions.php like this: require_once('functions1.php'); require_once('functions2.php'); require_once('functions3.php'); I'm wondering if it's possible to create an array of all these functions and their attributes? I'm thinking about something like: function my_functions() { require_once('functions1.php'); require_once('functions2.php'); require_once('functions3.php'); } And then some foreach loop, but I'm not sure how should it look like after all. I know this probably looks tricky, but I'm just curious if I'm able to list all my WordPress shortcodes without PHP's Reflection API :)

  • GA written in Java

    - by EnderMB
    I am attempting to write a Genetic Algorithm based on techniques I had picked up from the book "AI Techniques for Game Programmers" that uses a binary encoding and fitness proportionate selection (also known as roulette wheel selection) on the genes of the population that are randomly generated within the program in a two-dimensional array. I recently came across a piece of pseudocode and have tried to implement it, but have come across some problems with the specifics of what I need to be doing. I've checked a number of books and some open-source code and am still struggling to progress. I understand that I have to get the sum of the total fitness of the population, pick a random number between the sum and zero, then if the number is greater than the parents to overwrite it, but I am struggling with the implementation of these ideas. Any help in the implementation of these ideas would be very much appreciated as my Java is rusty.

  • iPhone: UIImageView not showing images

    - by George
    Hello, I've got UIImageView drawn in my nib-file and it's connected to a imageView iboutlet. I can load single pictures which will show up very nicely, but when it comes to drawing many images separately as like an animation, images won't show. I've got drawImage() function which takes NSData-objects(image data) and draws it to a screen(imageView). Main function has got for loop which loops 300 times as quickly as it can and each time it calls that drawImage function and passes different image data to it. Sometimes when I execute this code, last picture from that "animation" shows up, sometimes not at all. Maybe I need to schedule enough time for imageView so that the image can be shown? Hope someone has some clues. Thanks in advance!

  • Anchoring the Action URL of a Form

    - by John
    Hello, I am using a function that leads users to a file called "comments2.php": <form action="http://www...com/.../comments/comments2.php" method="post"> On comments2.php, data passed over from the form is inserted into MySQL: $query = sprintf("INSERT INTO comment VALUES (NULL, %d, %d, '%s', NULL)", $uid, $subid, $comment); mysql_query($query) or die(mysql_error()); Then, later in comments2.php, I am using a query that loops through entries meeting certain criteria. The loop contains a row with the following information: echo '<td rowspan="3" class="commentname1" id="comment-' . $row["commentid"] . '">'.stripslashes($row["comment"]).'</td>'; For the function above, I would like the URL to be anchored by the highest value of "commentid" for id="comment-' . $row["commentid"] . '" How can this be done? Thanks in advance, John

  • IE8 blocking JavaScript Cookies

    - by ossreleasefeed
    Hey there folks, Here is one that is throwing me for a loop. I am trying to set a simple cookie that has one name:value pair on IE8. Tested on FF and it works fine. IE8 keeps blocking it. I have read about the P3P stuff and created a basic P3P doc, no errors reported by the IBM tool, and added the following on all pages: <meta http-equiv="P3P" CP="CAO DSP COR PSDa CONi TELi OUR STP COM NAV"><link rel="P3Pv1" href="/w3c/p3p.xml"></link> The code I use to set the cookie is as follows: function setCompatibilityCookie(c_name, value, expiredays) { var exdate = new Date(); exdate.setDate(exdate.getDate() + expiredays); document.cookie= c_name + "=" + escape(value) + ((expiredays==null) ? "" : ";expires=" + exdate.toUTCString());} Any ideas why IE8 keeps blocking me from setting this cookie? Thank you, Schalk

  • Craft a JSONpath expression so that it retrieves only a specific value?

    - by Alex
    Hello, I have some JSON of which the following is a small sample: results": { "div": [ { "class": "sylEntry", "id": "sylOne", "div": [ { "class": "sT", "id": "sOT", "p": "Mon 11/17, Computer work time" }, { "class": "des", "id": "dOne", "p": "All classes Siebel 0218" } ] }, I would like to only retrieve the "p" content for the div element with class "sT". I would like to use a loop and doing something like this: var arrayOfResults = $.results..div.p does not work because I only want to retrieve the p value for the div element with class "sT". So how do I construct my JSONpath so that it will retrive the array of p elements that are contained within the divs class "sT". Thanks!!

  • DEADLOCK_WRAP error when using Berkeley Db in python (bsddb)

    I am using a berkdb to store a huge list of key-value pairs but for some reason when i try to access some of the data later i get this error: try: key = 'scrape011201-590652' contenttext = contentdict[key] except: print the error <type 'exceptions.KeyError'> 'scrape011201-590652' in contenttext = contentdict[key]\n', ' File "/usr/lib64/python2.5/bsddb/__init__.py", line 223, in __getitem__\n return _DeadlockWrap(lambda: self.db[key]) # self.db[key]\n', 'File "/usr/lib64/python2.5/bsddb/dbutils.py", line 62, in DeadlockWrap\n return function(*_args, **_kwargs)\n', ' File "/usr/lib64/python2.5/bsddb/__init__.py", line 223, in <lambda>\n return _DeadlockWrap(lambda: self.db[key]) # self.db[key]\n'] I am not sure what DeadlockWrap is but there isnt any other program or process accessing the berkdb or writing to it (as far as i know,) so not sure how we could get a deadlock, if its referring to that. Is it possible that I am trying to access the data to rapidly? I have this function call in a loop, so something like for i in hugelist: #try to get a value from the berkdb #do something with it I am running this with multiple datasets and this error only occurs with one of them, the largest one, not the others.

  • what are the advantages of C# over Python

    - by Matt
    I like Python mostly for the great portability and the ease of coding, but I was wondering, what are some of the advantages that C# has over Python? The reason I ask is that one of my friends runs a private server for an online game (UO), and he offered to make me a dev if I wanted, but the software for the server is all written in C#. I'd love to do this, but I don't really have time to do multiple languages, and I was just after a few more reasons to justify taking C# over Python to myself. I'm doing this all self-taught as a hobby, btw
