  • running requestAnimationFrame from within a new object

    - by JVE999
    I'm having trouble running an animation. This is inside var ob1 = function() {};. When called, it runs for a while and then I get the error Uncaught RangeError: Maximum call stack size exceeded. However, this same structure has no problems running outside of the object. /////////////// Render the scene /////////////// this.render = function (){ renderer.render(scene,camera); if(isControls == true) controls.update(clock.getDelta()); this.animate(); //console.log(true); requestAnimationFrame(this.render()); } /////////////// Update objects /////////////// this.animate = function (){ console.log("!"); }

  • discover if mod_rewrite is working (MAMP + codeigniter)

    - by Patrick
    Hi, I'm experimenting (and having problems!) with codeigniter. In particular, links do not work. even if they are correct (eg. http://localhost/ci-book/welcome/cat/3, where welcome is controller, cat the method), they can't be open and chrome says "Oops! This link appears to be broken...." Someone suggested to check that mod_rewrite is working. How can I do that? I'm using Mamp. thanks, P.

  • Why state cannot be part of Presenter in MVP?

    - by rFactor
    I read http://www.codeproject.com/KB/architecture/MVC_MVP_MVVM_design.aspx and it said: As powerful as they are, both MVC and MVP have their problems. One of them is persistence of the View’s state. For instance, if the Model, being a domain object, does not know anything about the UI, and the View does not implement any business logic, then where would we store the state of the View’s elements such as selected items? Fowler comes up with a solution in the form of a Presentation Model pattern. I wonder why Presenter can't hold View state? It already holds all View logic. As far as I understand, in MVC and MVP the state is kept in View. In PM and MVVM the state is kept in the Presentation Model. Why can't Presenter follow PM in this particular case and contain the state of the view? Here is another article which says Presenter does not hold View state, instead the view does: http://www.codeproject.com/KB/aspnet/ArchitectureComparison.aspx

  • How to learn to program C the right way

    - by sfactor
    i have been programming in C/C++ for my academic courses a lot and was under the impression i had a pretty good grasp of it. but lately i had to work in a bluetooth application that had a server and client implementation in a Linux box and an embedded system. i learned bluez bluetooth API, socket/network programming and coded it. however i ran into a lot of problems with memory leaks and segmentation faults and other memory related errors along the way.as the code grew more complex i all but lost control of the pointers and threads and sockets. this got me wondering that i had a lot to learn that they didn't say in the basic C/C++ books. so i wanted to ask for the resources that are available that'll help be code better in a professional way in C/C++ .especially for the Linux/Mac environment (gcc compiler).

  • PHP/Mysql issues

    - by queryne
    Php/my sql newbie question. I have a database I've imported into my local phpmyadmin. However it seems I can't access it from my a php application. The connection string seems right and when i try to authenticate user credentials to access database information, no problems. However authenticate everyone and knows when i put in fake credentials. Still it won't pull any other information from the database. For instance, once a users login they should see something like, "Hello username"... that kind of thing. At this point I see "Hello" without the username. Any ideas what i might be missing?

  • .htaccess not working in subfolder

    - by Staffan Estberg
    Hello, I have a couple of sites that are currently under development and I've put them under a specific subfolder for clients/co-workers to view - "http://dev.staffanestberg.com/site-name/". I've run into some problems getting the sites working with .htaccess. I can reach the index page by typing in the url for a site folder but neither img/style/js/etc linking or page rewriting works. Looking for a solution to this, Apache's "RewriteBase" seems to be the most likely one, however I can't get it to work. Tried RewriteBase http://dev.staffanestberg.com/site-name/ RewriteBase /site-name What would be the correct method? Thanks in advance, -Staffan

  • ruby1.9.1 can't find installed gems, yet ruby1.8 can...

    - by Zombies
    On ubuntu here. I installed both ruby1.8 and ruby1.9.1. I also ran these commands ruby1.8 setup.rb ruby1.9.1 setup.rb Both worked fine, I was also able to install gems for both. The gems in gem 1.9.1 and gem1.8 both show up correctly for gem list. The problems however begin with this: ruby1.9.1 some_script.rb. It cannot find any of the gems. I tried uncommenting some out figuring that parseconfig was the problem, yet it couldn't find any of the others, which are definetly in gem1.9.1 list. Any thoughts as to what is causing this/how to recover?

  • ASP.Net Roles: Page-Level Security Question

    - by jlrolin
    We're currently in the process of re-creating a brand new security model that dwarfs our existing process. Right now, we plan on grabbing a user's roles during the login process and then using a Base Page class to check if the user has the role of the corresponding page the user is navigating to. We can limit the menu's options by the user's roles as well, but we have had problems with users navigating to pages in our system by typing them in or having old bookmarks. Obviously, we need some sort of page level access. A simple function in our Base Page class that checks the role in the Arraylist against the page's assigned role would work, but I was wondering if there was any built-in functionality to support this or a cleaner solution possibly.

  • Is there a "vim runtime log"?

    - by Somebody still uses you MS-DOS
    Sometimes I try a customization/command in my vimrc. Everything seens to be correct, but it just doesn't work. It's difficult to know what's happening when vim starts, and know which command failed or not, so it's really difficult to debug what can be causing a problem in my vimrc. It's a trial-error approach, which is time consuming and really a PITA. For example, I'm having problems with snipmate plugin in some files and just don't have a clue on how to discover the problem. Is there a "runtime log" when vim starts, telling which commands it executed, which ones failed and such? This would help me a lot.

  • My AES encryption/decryption functions don't work with random ivecs

    - by Brendan Long
    I was bored and wrote a wrapper around openSSL to do AES encryption with less work. If I do it like this: http://pastebin.com/V1eqz4jp (ivec = 0) Everything works fine, but the default ivec is all 0's, which has some security problems. Since I'm passing the data back as a string anyway, I figured, why not generate a random ivec and stick it to the front, the take it back off when I decrypt the string? For some reason it doesn't work though. With random ivec: http://pastebin.com/MkDBFcn6 Well actually, it almost works. It seems to decrypt the middle of the string, but not the beginning or end: String is: 0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF Encrypting.. ???l%%1u???B! ?????`pN)?????[l????{?Q???2?/?H??y"?=Z?Cu????l%%1u???B!

Maybe some stupid mistake, or maybe I'm missing something about AES?

  • How to enable other languages for MailChimp List Subscribe Plugin?

    - by Lenin
    I have translated the MailChimp provided MailChimp List Subscribe Form plugin for wordpress. I used poEdit to edit. At wp-config.php I have language set as ar_SA. Which works for the themes I have used in two Bilingual sites. But the mo file had to be renamed to ar.mo I got two problems: While updating the catalog poEdit crashes. But I could save the .po and generated .mo successfully. The translated .mo doesn't appear for the confirmation success or error messages through the Ajax calls which its supposed to. I am submitting my .po file link here for experts to view. I have saved the settings for translation in the files. Translated Bangla.po file || Translated Arabic.po file

  • [SCORM 2004] the cmi.total_time parameter does not return anything.

    - by Nephila
    I am programming a SCORM 2004 product. I can update the session_time, it works. I can set the status (passed, failed, etc...) I also can get the cmi.location time. No problems! But I don't succeed atingt get the total time (cmi.total_time). I have tested on 2 LMS: On Ganesha the API.GetValue('cmi.total_time') is an empty string. On Moodle the API.GetValue('cmi.total_time') is just a "P". I do have the correct logs with correct session times. EDIT. I also try on cloud.scorm.com and cmi.total_time returns each time PT0H0M0S.

  • Reversing the effects of mkimage to get an original gzipped file back

    - by Alex Marshall
    Hello, We develop for a specific embedded device at our company, and part of that is making initial root disks that get loaded onto the devices over ethernet via netboot. We've experienced some problems, and as a result, the original folder with the contents of the initial root disks was lost along with its backups, but we do still have the initrd images, that have been created by gzipping the contents of a ramdisk that's been mounted as a local loop device, and then running mkimage on the gzipped file. Is there any way to undo the effects of mkimage and obtain the original gzipped content so that we can recover the original images ?

  • php session not working (as with cookies disabled), but cookies are enabled for the domain. What oth

    - by SWilk
    Hi, I have a problem with a client, who cannot log in to our system. We have PHP-based B2B system, which uses cookies to store session-id. The client cannot log in and is redirected to the login page, without any error message. He claims he have cookies enabled in his Firefox. Also, if he had cookies disabled, my javascript would detect this and would show him an red, very descriptive error info. He does not seen anything like this. What else could have same effect on sessions like disabled cookies in browser? Are there any proxies which filters cookies? Any AV software, etc? What to look for? Our login form works for any other user without problems.

  • What is possible causes of Jasper Exception

    - by CitadelCSCadet
    I have a JSP that takes an Arraylist from the session object and removes the items from it. It seemed to be working fine and then out of nowhere when I navigate to that page, the page is blank. I checked the tomcat log files and in catalina.out I am receiving a Jasper Exception an it is showing it as being on a line with the following for(int i; i < agentItems.size(); i++) agentItems is the name of the ArrayList I am using. I have been debugging it and cant seem to figure out what the problem might be. I have read that a JasperException is sometiems thrown as a JSP's NullPointerException. Is this true or am I just completely overlooking the problem? I have the web application running on a local machine and a intermediate server for development in which both of them have had no trouble. Why could it be that only on this server it is giving me problems?

  • For what purpose does java have a float primitive type?

    - by Roman
    I heard plenty times different claims about float type in java. The most popular issues typicaly regard to converting float value to double and vice versa. I read (rather long time ago and not sure that it's actual now with new JVM) that float gives much worse performance then double. And it's also not recommended to use float in scientific applications which should have certain accuracy. I also remember that when I worked with AWT and Swing I had some problems with using float or double (like using Point2D.Float or Point2D.Double). So, I see only 2 advantages of float over double: it needs only 4 bytes while double needs 8 bytes JMM garantees that assignment operation is atomic with float variables while it's not atomic with double's. Are there any other cases where float is better then double? Do you use float's in your applications? It seems to me that the only valuable reason java has float is backward compatibility.

  • How to inject dependencies into a CustomUserNamePasswordValidator in WCF?

    - by Dannerbo
    I'm using a UserNamePasswordValidator in WCF along with Unity for my dependency injection, but since WCF creates the instance of the UserNamePasswordValidator, I cannot inject my container into the class. So how would one go about this? The simplest solution I can think of is to create a static proxy/wrapper class around a static instance of a UnityContainer, which exposes all the same methods... This way, any class can access the container, and I don't need to inject it everywhere. So I could just do UnityContainerWrapper.Resolve() anywhere in code. So basically this solution solves 2 problems for me, I can use it in classes that I'm not creating an instance of, and I can use it anywhere without having to inject the container into a bunch of classes. The only downside I can think of is that I'm now potentially exposing my container to a bunch of classes that wouldn't of had access to the container before. Not really sure if this is even a problem though?

  • Max number of web methods?

    - by Rippo
    Guys I have a web service in asp.net 2.0 that has 234 methods. It seems that when I add another method the site does not compile in VS2005 until I remove one first. I get a message saying that the new method I just added does not exist in a file that belongs in the Microsoft.Net/.../Temporary Files directory. I have restarted IIS, closed down VS2005, removed all files from this temp directory but to no avail. The only way to get the code to compile is to remove another one so as to keep 234 methods.... I can consistency replicate this behaviour so it cannot be my code. Now I know this seems strange but it is true! One other strange thing is that exactly 100 of the method names begin with the word GetXXXyyyZZZ Has anyone else experienced problems with the maximum number of methods that are allowed in a web service? Many Thanks

  • How to check PHP filecode syntax in PHP?

I am on Windows, and I have tried system("C:\\Program Files (x86)\\PHP\\php.exe -l \"C:/Program Files (x86)/Apache/htdocs/a.php\"", $output); var_dump($output); without luck. The parameter -l should check for correct PHP syntax, and throw errors if some problems exist. Basically, I want to do something similar to this picture: That is, to be able to detect errors in code.

  • MS Access antiquated? Anything new in 2011?

    - by Heidi
    Our company has a database of 17,000 entries. We have used MS Access for over 10 years for our various mailings. Is there something new and better out there? I'm not a techie, so keep in mind when answering. Our problems with Access are: -no record of what was deleted, -will not turn up a name in a search if cap's or punctuation is not entered exactly, -is complicated for us to understand the de-duping process. - We'd like a more nimble program that we can access from more than one dedicated computer.

  • This PHP/Smarty doesn't work in IE

    - by Kyle Sevenoaks
    I'm starting to get sick of IE's random problems. Page link. (Add things to the cart with the kjøp button and handlevogn) I have this little tiny code here, {foreach $cart.taxes.$currency as $tax} <div id="subTotalCaption2"><p style="width:100px;">{$tax.name_lang}:</p></div> <div id="taxAmount2"><p>{$tax.formattedAmount}</p></div> {/foreach} That's meant to display the amount of total tax for each of the items in the basket. (MVA 25%) This works in every other browser but not IE. Why? Why not? Just why? Any help at all would be very much appreciated.

  • Transform PDF to HTML, keep layout

    - by Tgr
    What methods are there to transform a PDF to HTML? It could be anything - online service, software, library. (Opensource preferred. In the last case, php or python would be preferred.) It has to keep the original layout (including page numbers, footnotes and such), keep the images (combining them to one single background image per page is acceptable) and keep the links. It should preferably output valid XHTML and clean up PDF features such as ligatures, but if there is some post-processing required, I can live with that. Something with a clean, relatively semantic HTML output would be great. The closest one I found was zamzar.org, but it choked on links. (Also, the HTML output is an ugly heap of absolutely positioned divs and needs post-processing because of encoding problems.)

  • Technical reasons for not having large background images in websites

    - by kees-kist
    Most websites tend to have either a solid color as background, or a small image that is repeated. Why aren't more websites using a large image (such as a photo) as background? I can think of the following reasons: 1) Problems with different screen resolutions. Too small and gaps start to appear on the left and/or right side for higher resolutions, too big and lower resolutions only show part of the image. 2) Bandwidth. Although this is unlikely to be a problem for most websites. Are there any other reasons why such backgrounds are not being used more often?

  • C: Pointers to any type?

    - by dragme
    I hear that C isn't so type-safe and I think that I could use that as an advantage for my current project. I'm designing an interpreter with the goal for the VM to be extremely fast, much faster than Ruby and Python, for example. Now I know that premature optimization "is the root of all evil" but this is rather a conceptual problem. I have to use some sort of struct to represent all values in my language (from number over string to list and map) Would the following be possible? struct Value { ValueType type; void* value; } I would store the actual values elsewhere, e.g: a separate array for strings and integers, value* would then point to some member in this table. I would always know the type of the value via the type variable, so there wouldn't be any problems with type errors. Now: Is this even possible in terms of syntax and typing?
