  • Batch file to wait for other program to load/initialize, then execute command?

    - by Jason N
    I need some assistance writing what should be a fairly basic .BAT file. I load my main program, but that program takes ~20secs to load and be initialized. I have another command-line API I can execute to interact with this above program, but obviously until the above program is loaded and initialized there's no point in trying. If the program isn't running the command-line API returns a string stating exactly this - otherwise it just works and exits. Easy. So I want to wait until the above is loaded/initialized before firing my API command(s) at it. I could place a sleep/wait in there, but I want something more solid. The ~20sec wait is not necessarily consistent. Any way to execute the command-line API over and over until the response is satisfactory, then exit? J

  • Box-shadow and border-radius bug in Chrome

    - by Klaster_1
    Hello, I've been experimenting with CSS3 and found something strange. Heres's the part of DIV style: border:#446429 solid 1px; border-radius:15px; -moz-border-radius:15px; -webkit-border-radius:15px; box-shadow:3px 0px 15px #000000 inset,0px 3px 15px #000000 inset; -moz-box-shadow:3px 0px 15px #000000 inset,0px 3px 15px #000000 inset; -webkit-box-shadow:3px 0px 15px #000000 inset,0px 3px 15px #000000 inset; Rendering in Opera and Firefox are same and perfect: But Chrome renders shadow outside the border: Is it supposed to be so or I missed something important?

  • sending instant messages through python (msn)

    - by code_by_night
    ok I am well aware there are many other questions about this, but I have been searching and have yet to find a solid proper answer that doesnt revolve around jabber or something worse. (no offense to jabber users, just I don't want all the extras that come with it) I currently have msnp and twisted.words, I simply want to send and receive messages, have read many examples that have failed to work, and msnp is poorly documented. My preference is msnp as it requires much less code, I'm not looking for something complicated. Using this code I can login, and view my friends that are online (can't send them messages though.): import msnp import time, threading msn = msnp.Session() msn.login('[email protected]', 'XXXXXX') msn.sync_friend_list() class MSN_Thread(threading.Thread): def run(self): msn.start_chat("[email protected]") #this does not work while True: msn.process() time.sleep(1) start_msn = MSN_Thread() start_msn.start() I hope I have been clear enough, its pretty late and my head is not in a clear state after all this msn frustration. edit: since it seems msnp is extremely outdated could anyone recommend with simple examples on how I could achieve this? Don't need anything fancy that requires other accounts.

  • How to scan convert right edges and slopes less than one?

    - by Zachary
    I'm writing a program which will use scan conversion on triangles to fill in the pixels contained within the triangle. One thing that has me confused is how to determine the x increment for the right edge of the triangle, or for slopes less than or equal to one. Here is the code I have to handle left edges with a slope greater than one (obtained from Computer Graphics: Principles and Practice second edition): for(y=ymin;y<=ymax;y++) { edge.increment+=edge.numerator; if(edge.increment>edge.denominator) { edge.x++; edge.increment -= edge.denominator; } } The numerator is set from (xMax-xMin), and the denominator is set from (yMax-yMin)...which makes sense as it represents the slope of the line. As you move up the scan lines (represented by the y values). X is incremented by 1/(denomniator/numerator) ...which results in x having a whole part and a fractional part. If the fractional part is greater than one, then the x value has to be incremented by 1 (as shown in edge.incrementedge.denominator). This works fine for any left handed lines with a slope greater than one, but I'm having trouble generalizing it for any edge, and google-ing has proved fruitless. Does anyone know the algorithm for that?

  • Spaced repetition (SRS) for learning

    - by Fredrik Johansson
    A client has asked me to add a simple spaced repeition algorithm (SRS) for an onlinebased learning site. But before throwing my self into it, I'd like to discuss it with the community. Basically the site asks the user a bunch of questions (by automatically selecting say 10 out of 100 total questions from a database), and the user gives either a correct or incorrect answer. The users result are then stored in a database, for instance: userid questionid correctlyanswered dateanswered 1 123 0 (no) 2010-01-01 10:00 1 124 1 (yes) 2010-01-01 11:00 1 125 1 (yes) 2010-01-01 12:00 Now, to maximize a users ability to learn all answers, I should be able to apply an SRS algorithm so that a user, next time he takes the quiz, receives questions incorrectly answered more often; than questions answered correctly. Also, questions that are previously answered incorrectly, but recently often answered correctly should occur less often. Have anyone implemented something like this before? Any tips or suggestions? Theese are the best links I've found: http://en.wikipedia.org/wiki/Spaced_repetition http://www.mnemosyne-proj.org/principles.php http://www.supermemo.com/english/ol/sm2.htm

  • Vbscript - Compare and copy files from folder if newer than destination files

    - by Kenny Bones
    Hi, I'm trying to design this script that's supposed to be used as a part of a logon script for alot of users. And this script is basically supposed to take a source folder and destination folder as basically just make sure that the destination folder has the exact same content as the source folder. But only copy if the datemodified stamp of the source file is newer than the destination file. I have been thinking out this basic pseudo code, just trying to make sure this is valid and solid basically. Dim strSourceFolder, strDestFolder strSourceFolder = "C:\Users\User\SourceFolder\" strDestFolder = "C:\Users\User\DestFolder\" For each file in StrSourceFolder ReplaceIfNewer (file, strDestFolder) Next Sub ReplaceIfNewer (SourceFile, DestFolder) Dim DateModifiedSourceFile, DateModifiedDestFile DateModifiedSourceFile = SourceFile.DateModified() DateModifiedDestFile = DestFolder & "\" & SourceFile.DateModified() If DateModifiedSourceFile < DateModifiedDestFile Copy SourceFile to SourceFolder End if End Sub Would this work? I'm not quite sure how it can be done, but I could probably spend all day figuring it out. But the people here are generally so amazingly smart that with your help it would take alot less time :)

  • How do I add a textbox to my other jQuery click function?

    - by marcamillion
    Right now, my script adds a box to the cursor when I click on an image, as can be seen in the following code. Please note, this is jQuery. $(function() { var tag_box = $("<div>").appendTo("body").css({"width":"40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px"}); $("#image-wrapper").live('click', function(e){ tag_box.css({"left": e.pageX - 40, "top": e.pageY - 40, "display":"block"}); }); I would like to add a text field to appear right below that tag_box on that same click. I tried to do this, but it hasn't worked out like I thought it would: var comment_box = $("<label> Comment: <input type='text' name='comment' autocomplete='off'></label>"); $("#image-wrapper").live('click', function(){ $("body").append(comment_box); }); Any assistance you can give me, would be greatly appreciated. Thanks.

  • CSS button not styling

    - by o-logn
    Hey, I must be missing something obvious, but can someone explain what I'm doing wrong with my CSS? I would like all buttons to have a certain format, except a few. I was expecting to use CssClass in order to override the few that should be different, but they all seem to use the standard one. My CSS: .btn { border:none; background-color:red; } input[type="submit"] { border: 2px solid black; background-color:green; } All the buttons take the second value (green background, with a border). However, I have this button: <asp:Button ID="btnAdd" CssClass="btn" runat="server" Text="Add" /> I was expecting this to have no border, and a red background, but it's the same as every other button. Any ideas what I'm doing wrong? Thanks

  • Understanding the "Instantiation" of Actionscript/Flash Objects

    - by parallax7d
    Could someone expand and clarify the different logical instantiations of objects in actionscript? So far it seems there are 3 layers of instantiations, for lack of a better term. The first one is declaring a variable/type. Next is instantiating that variable with something solid in the code, like a method or function? Is this just a way to glue things together? Then after that you instantiate it on the stage, is this something you have to do explicitly, or is it a side effect? Is this "3 layer" concept the correct way of looking at it, kind of like the MVC for flash app logic?

  • XSLT transformations in Ruby and JRuby

    - by jpatokal
    Simple question: are there any solid XSLT libraries that work in both Ruby and JRuby? REXML works in both, but does not have XSLT support. ruby-xslt doesn't work in JRuby. The latest Nokogiri betas do support JRuby, but the support is still buggy and throws occasional NullPointerExceptions for XML input that works fine in Ruby. (In particular, any transforms that don't result in valid XML cause it to barf, even if xsl:output is set to 'text'!) JXslt is just a wrapper for Java's Xalan/Saxon and doesn't work in Ruby. Please tell me I'm missing something?

  • Text Hints with JQuery and JavaScript for loop

    - by lpdahito
    Hey guys! I'm developing a small app where i ask users to put some info. I want to show text hints in the input fields. I do this in a for loop... When the page is loaded, the hints are displayed correctly but nothing happens on 'focus' and 'blur' events... I'm wondering why since when I don't use a 'for loop' in my js code, everything works find... By the way the reason I use a for loop is because I don't want to repeat myself following 'DRY' principles... Thx for your help! LP Here's the code: <script src="/javascripts/jquery.js" type="text/javascript"></script> <script type="text/javascript"> var form_elements = ['#submission_url', '#submission_email', '#submission_twitter'] var text_hints = ['Website Address', 'Email Address', 'Twitter Username (optional)'] $(document).ready(function(){ for(i=0; i<3; i++) { $(form_elements[i]).val(text_hints[i]); $(form_elements[i]).focus(function(i){ if ($(this).val() == text_hints[i]) { $(this).val(''); } }); $(form_elements[i]).blur(function(i){ if ($(this).val() != text_hints[i]) { $(this).val(text_hints[i]); } }); } }); </script>

  • How to add css to form elements if attribute class is already being used in Jquery

    - by Gublooo
    Hey guys This is probably a dumb question - I'm using Jquery to validate the form. So the form elements have the class="required" attribute. input type="text" name="last_name" class="required"/ Now if i want to apply some css properties to the input fields of this form - how do I do that. I do not want to declare a general css for all input elements - I have declared the css as follows: input.form { color: #000; background: #fff; border: 2px solid #E1E1E1; font-size: 16pt; width:150px; } And I want to use it this way input class="form" type="text" name="last_name" class="required"/ But this wont work as there are two class attributes here. So how do I handle this. Thanks

  • Branchless memory manager?

    - by Richard Fabian
    Anyone thought about how to write a memory manager (in C++) that is completely branch free? I've written a pool, a stack, a queue, and a linked list (allocating from the pool), but I am wondering how plausible it is to write a branch free general memory manager. This is all to help make a really reusable framework for doing solid concurrent, in-order CPU, and cache friendly development. Edit: by branchless I mean without doing direct or indirect function calls, and without using ifs. I've been thinking that I can probably implement something that first changes the requested size to zero for false calls, but haven't really got much more than that. I feel that it's not impossible, but the other aspect of this exercise is then profiling it on said "unfriendly" processors to see if it's worth trying as hard as this to avoid branching.

  • Module based web project directory layout with git and symlinks

    - by karlthorwald
    I am planning my directory structure for a linux/apache/php web project like this: Only www.example.com/webroot/ will be exposed in apache www.example.com/ webroot/ index.php module1/ module2/ modules/ module1/ module1.class.php module1.js module2/ module2.class.php module2.css lib/ lib1/ lib1.class.php the modules/ and lib/ directory will only be in the php path. To make the css and js files visible in the webroot directory I am planning to use symlinks. webroot/ index.php module1/ module1.js (symlinked) module2/ module2.css (symlinked) I tried following these principles: layout by modules and libraries, not by file type and not by "public' or 'non public', index.php is an exception. This is for easier development. symlinking files that need to be public for the modules and libs to a public location, but still mirroring the layout. So the module structure is also visible in the resulting html code in the links, which might help development. How will git handle the symlinking of the single files correctly, is there something to consider? When it comes to images I will need to link directories, how to handle that with git? modules/ module3/ module3.class.php img/ img1.jpg img2.jpg img3.jpg They should be linked here: webroot/ module3/ img/ (symlinked ?) So this is a git and symlink question. But I would be interested to hear comments about the php layout, maybe you want to use the comment function for this.

  • Java method keyword "final" and its use

    - by Lukas Eder
    When I create complex type hierarchies (several levels, several types per level), I like to use the final keyword on methods implementing some interface declaration. An example: interface Garble { int zork(); } interface Gnarf extends Garble { /** * This is the same as calling {@link #zblah(0)} */ int zblah(); int zblah(int defaultZblah); } And then abstract class AbstractGarble implements Garble { @Override public final int zork() { ... } } abstract class AbstractGnarf extends AbstractGarble implements Gnarf { // Here I absolutely want to fix the default behaviour of zblah // No Gnarf shouldn't be allowed to set 1 as the default, for instance @Override public final int zblah() { return zblah(0); } // This method is not implemented here, but in a subclass @Override public abstract int zblah(int defaultZblah); } I do this for several reasons: It helps me develop the type hierarchy. When I add a class to the hierarchy, it is very clear, what methods I have to implement, and what methods I may not override (in case I forgot the details about the hierarchy) I think overriding concrete stuff is bad according to design principles and patterns, such as the template method pattern. I don't want other developers or my users do it. So the final keyword works perfectly for me. My question is: Why is it used so rarely in the wild? Can you show me some examples / reasons where final (in a similar case to mine) would be very bad?

  • Compressing three individual jpeg pics containing temporal redundancy?

    - by michael
    I am interfacing and embedded device with a camera module that returns a single jpeg compressed frame each time I trigger it. I would like to take three successive shots (approx 1 frame per 1/4 second) and further compress the images into a single file. The assumption here is that there is a lot of temporal redundancy, therefore lots of room for more compression across the three frames (compared to sending three separate jpeg images). I will be implementing the solution on an embedded device in C without any libraries and no OS. The camera will be taking pics in an area with very little movement (no visitors or screens in the background, maybe a tree with swaying branches), so I think my assumption about redundancy is pretty solid. When the file is finally viewed on a pc/mac, I don't mind having to write something to extract the three frames (so it can be a nonstandard cluge) So I guess the actual question is: What is the best way to compress these three images together given the fact that they are already in JPEG format (it is a possibly to convert back to a raw image, but if i dont have too...)

  • Rails : fighting long http response times with ajax. Is it a good idea? Please, help with implementa

    - by baranov
    Hi, everybody! I've googled some tutorials, browsed some SO answers, and was unable to find a recipe for my problem. I'm writing a web site which is supposed to display almost realtime stock chart. Data is stored in constantly updating MySQL database, I wrote a find_by_sql query code which fetches all the data I need to get my chart drawn. Everything is ok, except performance - it takes from one second to one minute for different queries to fetch all the data from the database, this time includes necessary (My)SQL-server side calculations. This is simply unacceptable. I got the following idea: if the data is queried from the MySQL server one point a time instead of entire dataset, it takes only about 1-100ms to get an individual point. I imagine the data fetch process might be browser-driven. After the user presses the button in order to get a chart drawn, controller makes one request to the database and renders, say, a progress bar, say 1% ready. When the browser gets the response, it immediately makes an (ajax) request, and the server fetches the next piece of data and renders "2%". And so on, until all the data is ready and the server displays the requested chart. Could this be implemented in rails+js, is there a tutorial for solving a similar problem on the Web? I suppose if the thing is feasible at all, somebody should have already done this before. I have read several articles about ajax, I believe I do understand general principles, but never did nontrivial ajax programming myself. Thanks for your time!
