  • web applications tend to have a admin panel?

    - by ajsie
    i wonder if large web applications like twitter and facebook have admin panels to handle CRUD for users, posts, images, themes and so on just like in CMS like drupal? so programmers have to code the front for the regular users AND back for the administrators? if i develop an web application is it recommended that i also code the admin part? or is it unnecessary since i can handle all directly in mysql and by editing php scripts directly? share your thoughts! thanks

  • Django: What's the correct way to get the requesting IP address?

    - by swisstony
    I'm trying to develop an app using Django 1.1 on Webfaction. I'd like to get the IP address of the incoming request, but when I use request.META['REMOTE_ADDR'] it returns 127.0.0.1. There seems to be a number of different ways of getting the address, such as using HTTP_X_FORWARDED_FOR or plugging in some middleware called SetRemoteAddrFromForwardedFor. Just wondering what the best approach was?

  • how to get memory dump after blue screen

    - by user464164
    I'm getting a lovely BSOD on bootup (STOP: 0x0000007E) from a driver I'm writing, and would like to load up the memory dump for analysis. However, it's not getting dumped anywhere. Everything is setup correctly in the Startup and Recovery settings, but I get no dump file, and nothing in the event log stating a dump has taken place. It looks like a dump is not even occurring... I know the exact line of code causing it (a call to IoAttachDevice()), but am not sure why, and would like to view the DbgPrint output to see where exactly it's failing. Could Windows possibly be crashing before the dumping functionality is set up? If so, how do I get access to the state of the machine when the failure occurs? UPDATE: Other possibly useful information: I'm running Windows XP through VirtualBox on a Linux host.

  • Admin auto generation

    - by Me-and-Coding
    Hi, I create custom CMS sites and then go ahead for the backend/admin side. Is there any tool out there to automatically create admin side of my sites, for example, based on table relationships or whatever customization we may put in place. PHPMaker seems to claim something like what i ask for but i have not used it. Any tool out there to auto-create admin side or PHPMaker is up to the point? Thanks

  • Displaying "broken" sprites?

    - by Roman
    I'm quite new to the world of 2D-Engines. I figured out how to load images and display those as sprites and stuff, but theres one question that bugs me. For instance, when a "rocket" hits an object it will deal damage to it and leave a crater behind. I'd like to have the crater shown on that object. That would require "skipping" some of the pixels of that image when rendering, doesn't it? My question is, how would you do such a thing? What data strcture would you use to save this? How to display a "broken" sprite?

  • how many color combinations in a 24 bit image

    - by numerical25
    I am reading a book and I am not sure if its a mistake or I am misunderstanding the quote. It reads... Nowadays every PC you can buy has hardware that can render images with at least 16.7 million individual colors. Rather than have an array with thousands of color entries, the images instead contain explicit color values for each pixel. A 24-bit display, of course, uses 24 bits, or 3 bytes per pixel, for color information. This gives 1 byte, or 256 distinct values each, for red, green, and blue. This is generally called true color, because 256^3 (16.7 million) He says 1 byte is equal to 256 distinct values. 1 byte = 8 bits. 8^2 bits = 64 distinct colors right ?? It's not adding up right to me. I know it might be something simple to understand, but I don't understand.

  • Timer running while on home screen iPhone - Objective C

    - by Franky
    Hello, I am interested in building a Timer Based game such as mafia wars or soemthing like that. I'm stuck on one question. What would be the best way to retain a timer, even if the app is closed? Should I do this based on the Device Clock? or should I set a time to a server, and get the time when the device starts up? If any one knows a better way for this, let me know. Thanks. @lessfame

  • Code promotion: Enforcing the rules

    - by jbarker7
    So here is our problem: We have a small team of developers with their own ways of doing things-- I am trying to formalize a process in which we are required to promote our code in the following order: Local sandbox Dev UAT Staging Live Developers develop/test as they go on their own sandbox, Dev is its own box that we would use for continuous integration, UAT is another site in IIS on the dev box, which uses our dev database. We then promote to staging, which is a site in IIS on the Live box and using live data (just like the live, hence staging). Then, finally, we promote to live. Here are a few of my questions: 1.) Does this seem to be best practice? If not, what needs to be done differently? 2.) How do I enforce the rules to the developers? Often developers skip steps in order to save time... this should not be tolerated and would be great if it could be physically enforced. 3.) How do I enforce these rules to the business group? The business group just wants to get features out FAST. Do we promote only on certain days? Thanks! Josh

  • Capture form fields and repopulate the form with them

    - by Joel Cunningham
    I am currently testing a large web form and would like to be able to easily populate the form with several different lots of test data without having to type them each time. Is there a generic way to capture form inputs on a web page and have them repopulated on a different page load? I thought a tool like greasemonkey might be able to do something like this.

  • Integrate ClickOnce update in a setup

    - by Erick
    As recent decision in my team we decided to deploy a software we develop for some time now in ClickOnce. Previously it was deployed with a merge module in a setup project. We had in mind to actually deploy the ClickOnce setup/updater in the web server setup. The problem here would not exactly to integrate it but to make sure to limit the human work to integrate it. Normally I guess it would be necessary to "add - file" and select the folder containing the setup.exe + publish.htm + application files + .application, but I fear that for each time we publish a new version to the hard drive we have to update the setup project as well. Would someone have some insight to help that ? (especially to not have to add the program_[version] folder inside application files that is created each time a new publish is done).

  • Using mercurial for web-design version control (dealing with images)

    - by Acorn
    I'm very new to Version Control, and I was wondering if I could get some advice on how it can fit into website design. At the moment I'm working on a typical, simple website that includes images: A few .html files and a .css file One folder full of photographs Another folder with the corresponding thumbnails Can I just put the whole lot in a repository? Or is there a better way I could apply Version Control to it? How should I deal with the images? edit: How well will it work with changes to the images? What if I decide to try and optimise my photographs or resize them. I wont be able to see what exactly changed about the images, should comments be enough to keep track of that?

  • What are your feelings on JavaFX?

    - by ForYourOwnGood
    I currently do a lot of work in ActionScript 3.0, I also love to program in Java. Is JavaFX perfect for me? What is the general feeling on JavaFX, will it become a power house, or go down the same path as Java Applets? Could the designers I work with become comfortable with JavaFX to the same extent they are comfortable with ActionScript and JavaScript?

  • Getting batch_action functionality in Symfony 1.0

    - by Alex Ciminian
    I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. I'm new to Symfony, so any help would be appreciated :). Thanks, Alex Update list: display: [id, =name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ actions: _create: ~ export_csv: name: Export to CSV action: CSVExport params: id=csvActionSubmit filters: [name, county_id, _status_filter, activity_id] fields: id: name: Nr. crt. ... Thanks to your advice, I've managed to add a button that is linked to my action. The problem is that I also need to send some parameters to the action, because I may not want all the elements - filters may have been used. Unfortunately, the project is using Symfony 1.0, which doesn't support batch_actions. Currently, I'm working around this with Javascript (I parse the DOM to get the numeric ids (from the display table) and then build the link for the button. I really think there could be a better way for this.

  • What is the preferred way of loading browser-specific CSS files?

    - by Yuval A
    What is the best way to handle browser-specific CSS file loading? Assume you are running in the context of a proper MVC framework. Here are some options, you are free to discuss the pros and cons of these options as well as any other methods you know of, and prefer: Server-side solution: use the controller (e.g. servlet) to analyze the user-agent header in the request and return the proper CSS file in the view. Use browser specific hacks to load files, such as: <!--[if IE]> ... <![endif]--> Load CSS files asynchronously in client side by inspecting user-agent and adding respective files Use a client side framework to handle browser-specifics (such as jQuery browser-specific css rules)

  • Do you think the AI industry will ever come back?

    - by Isaiah
    I just spent some time reading about the collapse of the AI industry and realized a lot of the reason it failed was because technology was slow to catch up with their theories on when it would be available. I also read that it is believed computers that will be able to emulate human synapses may be made round 2015-2025. It's 2010 now and were getting pretty close to that time frame. I was wondering if anyone thinks that the AI industry will return as the technology lands? And if so, will it change the language market? Could Lisp like languages suddenly experience a burst of growth if it does? Idk I just thought it was interesting thinking about it.

  • Should I design the application or model (database) first?

    - by YonahW
    I am getting ready to start building a new web project in my spare time to bring to fruition an idea that has been bouncing around my head for a while. I have never gotten down whether I am better off first building the model and then the consuming application or the other way around. What are the best practices? What would you build first and why? I imagine that in general the application should generally drive the model, however the application like many websites really doesn't do much without the model. For some reason I find it easier at times to think in terms of the model since the application is really just actions on the model. Is this a poor way of thinking about things? What advantages/disadvantages does each option have?
