  • Keeping updated with the latest technologies.

    - by Prashanth
    I am a software developer and I have been programming since the past six years. I simply love the mental challenge involved in trying to come up with solutions to hard problems, reading up programming literature, blogs by prominent developers and so on. I work on Microsoft platform and I have trouble keeping up with the pace at which various frameworks are rolled out. Remoting,WCF,ASP.NET,ASP.NET MVC, LINQ, WPF, WWF, OSLO, ADO.NET data services, DSL tools etc etc. Even understanding all these frameworks at an abstract level and see how they are all tied up with MS vision itself is a major hurdle. Now when you add other non microsoft technologies, programming languages etc to the equation, I wonder how do people manage? Given that there are only 24 hours in a day, how does one keep himself updated about so many technology changes that happen everyday? My question is , is it even worth doing that? The thing is, I am also interested in other fields such as literature, science. I try my best to at least gain a superficial understanding of what is happening in other fields of my interest and don't want to give up on that :)

  • Testing for security vulnerabilities on web applications

    - by Moak
    A lot of companies use CMS software that updates on the regular, often they are security fixes, implying that the previous version have security vulnerabilities. But most clients never upgrade this, or even the CMS has been modified so that an update would break the site. Are there sites that document these exploits, and instruct how to test for them? Or does this information not even get published? (in order not to have people try to exploit them) Also is there a generic php/js based check list to prevent hack attempts? I know about SQL injections and XSS, but I'm sure that there are more threats out there. Peace

  • Deal with undefined values in code or in the template?

    - by David
    I'm writing a web application (in Python, not that it matters). One of the features is that people can leave comments on things. I have a class for comments, basically like so: class Comment: user = ... # other stuff where user is an instance of another class, class User: name = ... # other stuff And of course in my template, I have <div>${comment.user.name}</div> Problem: Let's say I allow people to post comments anonymously. In that case comment.user is None (undefined), and of course accessing comment.user.name is going to raise an error. What's the best way to deal with that? I see three possibilities: Use a conditional in the template to test for that case and display something different. This is the most versatile solution, since I can change the way anonymous comments are displayed to, say, "Posted anonymously" (instead of "Posted by ..."), but I've often been told that templates should be mindless display machines and not include logic like that. Also, other people might wind up writing alternate templates for the same application, and I feel like I should be making things as easy as possible for the template writer. Implement an accessor method for the user property of a Comment that returns a dummy user object when the real user is undefined. This dummy object would have user.name = 'Anonymous' or something like that and so the template could access it and print its name with no error. Put an actual record in my database corresponding to a user with user.name = Anonymous (or something like that), and just assign that user to any comment posted when nobody's logged in. I know I've seen some real-world systems that operate this way. (phpBB?) Is there a prevailing wisdom among people who write these sorts of systems about which of these (or some other solution) is the best? Any pitfalls I should watch out for if I go one way vs. another? Whoever gives the best explanation gets the checkmark.

  • Using GET instead of POST to delete data behind authenticated pages

    - by Matt Spradley
    I know you should use POST whenever data will be modified on a public website. There are several reasons including the fact that search engines will follow all the links and modify the data. My question is do you think it is OK to use GET behind authenticated pages in something like an admin interface? One example would be a list of products with a delete link on each row. Since the only way to get to the page is if you are logged in, is there any harm in just using a link with the product ID in the query string?

  • Where can I get a theme/template suitable for a webapp?

    - by swisstony
    I'm building a simple web application that is mainly going to be displaying small tables of data back to the user. The problem is I can't do design to save my life. I need a simple web 2.0 style template that is CSS/HTML compliant. I know about http://themeforest.net and http://www.oswd.org/. Just wondering if there are any other sites that have a good selection of templates suitable for web apps.

  • Which Ipod touch generation should I buy? 2nd or 3rd?

    - by kukabunga
    I want to create games for Iphone/Ipod touch. Unfortunately I don't have a lot of money so I can buy only one device. Ipod is cheaper than Iphone, so I decided to bought Ipod touch. But I am afraid of buying 3rd generation - because it has more memory, more faster CPU, etc. And I think if I post my app on appstore - people with 2nd generation Ipod might have trouble with my app (because I was testing it on 3rd generation). But on the other hand - I am planning to create 3d/cpu demanding game - and it would be easy for me to implement it on device with more calculation power... What should I do in this situation? Any advice is appreciate.

  • SEO google keyword position tools?

    - by Peterl86
    Hi guys, I want to check our google postions for several keywords every day and make a note in a spreadseet. At the moment, we have a student doing it but it's a rubbish job and it doesn't seem fair on them! Are there any tools available to automate this process? I have tried rankchecker by seobook.com, but although that should be exactly what im looking for when i set scheduled tasks in that, it doesnt work. Any tips would be appreciated, thanks! peter EDIT: Liam has suggested a Python script to do this, which unfortunately isnt something I'm very familiar with! If anyone knows of a good tutorial or something to help us with this, that would be brilliant. Update: Found a php script at seoscript.net which looks like a step in the right direction. But I cant get it to work! I get this error. Anyone more knowledgabe than me know how to fix that? I have PEAR installed. thanks again, Peter

  • Documenting software architectures that serve multiple markets

    - by wsb3383
    Hello, I'm the lead developer/architect wanna-be on a J2EE based system/platform at work that serves both real estate and automotive markets. The systems consists of a set of database back ends, web services and two web clients. The platform ends up serving 3 different products: an internal vehicle inventory system for use by company analysts, an external dealer management system (commercialized product), and a real estate inventory system (commercialized). In other words, it follows a software product lines approach....My question is, I'm having trouble communicating to other technical and some business people how this platform architecture is one system that serves multiple markets (by leveraging some existing assets combined with minor modifications)....Is there a formal modeling language that can simplify communicating this intent? I should note that I haven't read much about software product lines, so I'm not sure if there is actually a standard modeling approach to SPL that i'm not aware of....I'm also interested in knowing if there are special configuration management practices for such systems. thanks,

  • Is there a way to add an MP3 player to my website so that iPhone & iPad users can use it.

    - by codingguy3000
    I have a website www.askvioletnow.com. I added a flash mp3 player that plays a sound clip when you go to the page. I know Flash doesn't work on the iPhone OS, but is there a way to get this type of mp3 player to work on an iPhone? I'm thinking maybe a javascript mp3 player. What I would ultimately want is to replace my flash mp3 player with a different mp3 player and have it so the player is available on Windows and Mac computers as well as iPhone devices. Thanks in advance.

  • Offline mode app in a (HTML5) browser possible?

    - by Horace Ho
    Is it possible to build an application inside in browser? An application means: 1 Where there is connection (online mode) between the browser and an remote application server: the application runs in typical web-based mode the application stores necessary data in offline storage, to be used in offline mode (2) the application sync/push data (captured during offline mode) back to the server when it is resumed from offline mode back to online mode 2 Where there is no connection (offline mode) between the browser and an remote application server: the application will still run (javascript?) the application will present data (which is stored offline) to user the application can accept input from user (and store/append in offline storage) Is this possible? If the answer is a yes, is there any (Ruby/Python/PHP) framework being built? Thanks

  • please we need php replacement on linux.

    - by diamandiev
    PHP is just awful but atm the only cheap server technology available. If you want free hosting you are stuck with php. If you want cheap hosting too. Windows hosting is like 3x the pice. It's amazing how much effort people put into executing a task in php while they could this 10 times faster and better with a real language/server platform (asp.net). Just my 2 cents.

  • Surface Detection in 2d Game?

    - by GamiShini
    I'm working on a 2D Platform game, and I was wondering what's the best (performance-wise) way to implement Surface (Collision) Detection. So far I'm thinking of constructing a list of level objects constructed of a list of lines, and I draw tiles along the lines. ( http://img375.imageshack.us/img375/1704/lines.png ). I'm thinking every object holds the ID of the surface that he walks on, in order to easily manipulate his y position while walking up/downhill. Something like this: //Player/MovableObject class MoveLeft() { this.Position.Y = Helper.GetSurfaceById(this.SurfaceId).GetYWhenXIs(this.Position.X) } So the logic I use to detect "droping/walking on surface" is a simple point (player's lower legs)-touches-line (surface) check (with some safety approximation - let`s say 1-2 pixels over the line). Is this approach OK? I`ve been having difficulty trying to find reading material for this problem, so feel free to drop links/advice.

  • How do you create multiple versions of an ActiveX control?

    - by Peter Ruderman
    Hopefully this is a straightforward question, but googling has proved fruitless (and frustrating, to say the least). Links to good documentation would be greatly appreciated. Here's the problem. We have a web application with an associated ActiveX control. (The control wraps a crufty old MFC application if it matters.) Moving forward, we expect to release multiple versions of this application, and each will have a corresponding version of the control. If someone accesses two versions of the web application, then that user should end up with two different versions of the control on his system. (The controls should play nice and not clobber each other.) In addition, I want to automate this process. Our system has a global version number that applies to all components. If we change the version number, the next build should produce a new version of the control. What's the best way to do this?

  • Generic documentation guide-lines for implementation details

    - by mgj
    Hi..:) For documentation and presentation purposes, we often find professionals/students creating SRS, coding guidelines etc. for these things there is some kind of a checklist which one could use to appropriately match what could relate to a specific case and accordingly one does a documentation for each. On those grounds could you please give me some sort of a checklist( any points/guidelines) one could use for going about Implementation( in the form of Implementation Details) in Python and C++ . Although this might sound specific as the query is "Implementation Details" and is different for different cases as one goes about the REAL implementation, I just want a SET of guidelines one should follow ( Preferably In Python, C++ specific, even for any other language is Welcome) if this( Implementation Details ) has to also be documented or presented. Hope the question is clear, I am sorry if it still sounds ambiguous, I guess this is the best I could do to frame my query. Thank you for your time...:)

  • Android: How to invalidate multiple parts of screen

    - by user342731
    I need to be able to selectively invalidate multiple (about 20) rectangles on the screen for performance reasons, so tried the following: Vector<Rect> myRects = new Vector<Rect>(); // ... add some Rects to myRects for (Rect r : myRects) { invalidate(r); } However this seems to invalidates a union of all the Rect's, forming one large rectangle which covers all of small ones I'm trying to invalidate. How can one invalidate multiple areas on the screen, and only those areas?

  • JSP template inheritance

    - by Ryan
    Coming from a background in Django, I often use "template inheritance", where multiple templates inherit from a common base. Is there an easy way to do this in JSP? If not, is there an alternative to JSP that does this (besides Django on Jython that is :) base template <html> <body> {% block content %} {% endblock %} </body> <html> basic content {% extends "base template" %} {% block content %} <h1>{{ content.title }} <-- Fills in a variable</h1> {{ content.body }} <-- Fills in another variable {% endblock %} Will render as follows (assuming that conten.title is "Insert Title Here", and content.body is "Insert Body Here") <html> <body> <h1>Insert title Here <-- Fills in a variable</h1> Insert Body Here <-- Fills in another variable </body> <html>

  • Why does multiple sessions started on the same page gets the same session id?

    - by Calmarius
    I tryed the following: <?php session_name('user'); session_start(); // sets an 'user' cookie with session id. // This session stores the user's login data. // Its an ordinary session. $USERSESSION=$_SESSION; // saving this session $userSessId=session_id(); session_write_close(); //closing this session session_name('chatroom'); session_start(); // set a 'chatroom' cookie but contains the same session id and points to the same data :( . // This session would be used to store the chat text. This session would be // shared between all users joined in this chat room by setting the same session id for all members. // by calling session_regenerate_id would make a diffent session id for every user and it won't be a chat room anymore. ?> So I want to do a chat like thing with sessions. On the client side it would be done with ajax that polls this php page in every 5-10 seconds. Sessions may be cached in the server's memory so it can be accessible fast. I can store the chat in the database but my service runs on a free webhost which is limited, only 4 mysql connections allowed at a time which is almost nothing. I try to touch my database as least times as possible.
