  • Using AntiXss As The Default Encoder For ASP.NET

    Scott Guthrie recently wrote about the new <%: %> syntax for HTML encoding output in ASP.NET 4. I also covered the topic of HTML encoding code nuggets in the past as well providing some insight into our design choices for the approach we took. A commenter to Scotts blog post asked, Will it be possible to extend this so that is uses libraries like AntiXSS instead? See: http://antixss.codeplex.com/ The answer is yes! ASP.NET 4 includes a new extensibility point which allows you to replace...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • IValidatableObject vs Single Responsibility

    - by Boris Yankov
    I like the extnesibility point of MVC, allowing view models to implement IValidatableObject, and add custom validation. I try to keep my Controllers lean, having this code be the only validation logic: if (!ModelState.IsValid) return View(loginViewModel); For example a login view model implements IValidatableObject, gets ILoginValidator object via constructor injection: public interface ILoginValidator { bool UserExists(string email); bool IsLoginValid(string userName, string password); } It seems that Ninject, injecting instances in view models isn't really a common practice, may be even an anti-pattern? Is this a good approach? Is there a better one?

  • what is best book to learn optimized programming in java [closed]

    - by Abhishek Simon
    Possible Duplicate: Is there a canonical book for learning Java as an experienced developer? Let me elaborate a little: I used to be a C/C++ programmer where I used data structure concept like trees, queues stack etc and tried to optimize as much as possible, minimum no. of loops, variables and tried to make it efficient. It's been a couple of years that I started writing java codes, but it is simply not that efficient in terms of performance, memory intensive etc. To the point: I want to enter programming challenges using java so I need to improve my approach at things I program. So please suggest me some books that can help me learn to program better and have a chance in solving challenges in programming.

  • SEO consequences for merging country sites in a .com

    - by Pekka
    I am in the process of refactoring a number of rental portals I've built for a company with locations in Austria, Germany, Switzerland, and the Netherlands. Instead of the current setting of each country site running under its own domain name: www.companyname.de www.companyname.ch www.companyname.at I would love to merge them all in this way: www.companyname.com/de www.companyname.com/ch www.companyname.com/at with the country TLDs doing a 301 redirect to the respective .com address. However, I have been repeatedly told not to do this due to likely problems with SEO - the business is very SEO dependent, and being a rental chain, needs to be strong in local results. So the question is: Is there an unavoidable hit in Search Engine Optimization when redirecting to a central .com domain? What measures can be taken to soften the blow? What comes to my mind is explicitly specifying a lang attribute in the html tag. Are there any other ways to specifically point out geographical location for sub-directories?

  • What is the best way to learn how to develop drivers?

    - by Kenneth
    At some point in my career I would definitely like to get involved in some embedded programming. I was thinking that starting out with developing some drivers would be a good place to develop my abilities in the regard. I'm open to doing so on either windows or linux platform (eventually will want to probably attempt both). What tools would you recommend that I look into to get me started on this project? Any other resources that you have found to be helpful (i.e. books, websites, programs, etc)? Any advice/recommendations? Thanks!

  • Developing payment gateway.

    - by kmaxat
    Hello, I have an idea of developing internet payment gateway similar to PayPal or Webmoney. Since i'm only sophomore at Computer Science, and i've only taken intermediate programming classes, i've no idea where to search for general information about this topic. I do understand that this kind of project is CLEARLY too much to handle for sophomore. Since, it's forum for Pro Webmasters, and probably some of you can point direction of study. What book/source/article would you suggest to read to understand fundamentals of internet payment? What book/source/article would you suggest to read to understand fundamentals internet security? What language is most commonly used for developing payment security of website? I appreciate any help. Thank you.

  • After installing Ubuntu using WUBI, starting Ubuntu does not get further than the GRUB prompt

    - by Kris Everett
    I'm trying to install Ubuntu. I put Ubuntu on a USB flash drive using the WUBI installer. I get to where it finishes the install and it wants me to reboot. But when I reboot and then select Ubuntu, I get a black screen that says GNU GRUB version 1.99-21ubuntu3 Minimal BASH-like editing is supported. for the first word. TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. Grub> When I type in some commands it says "Kernel not specified" and the rest of the commands give no feed back what so ever. What did i do wrong? Can anyone point me in the right direction. Please help this is very frustrating any help would be useful.

  • JavaOne and Oracle Open World Community Run - Monday, Oct 1, 6:17am PT

    - by arungupta
    Following the tradition from last year, inviting all JavaOne and Oracle Open World attendees to run with me in one of the 10 best cities to run in the US. The running route will start at Ferry Plaza on Embarcadero, go through Fisherman's Wharf, straight up Hyde St, couple of loops around Crooked Street and then back the same route to end at Ferry Plaza. Here is the complete clickable map: The Hyde Street (~300ft in 0.75 miles) and Lombard (~200 ft in 0.15 mile) are challenging elevations and you may cover them once only. Alternatively you may take a simpler route out-and-back by running further up to Marina and Crissy Field. When ? Monday, Oct 1, 2012 I plan to leave at 6:17am PT from the starting point and certainly hope you can join me. Oracle is doing several things to keep Oracle Open World and JavaOne sustainable and reduce the conference footprint. Lets do our share to keep the conference green! Of course, don't forget the Geek Bike Ride is tomorrow.

  • Do immutable objects and DDD go together?

    - by SnOrfus
    Consider a system that uses DDD (as well: any system that uses an ORM). The point of any system realistically, in nearly every use case, will be to manipulate those domain objects. Otherwise there's no real effect or purpose. Modifying an immutable object will cause it to generate a new record after the object is persisted which creates massive bloat in the datasource (unless you delete previous records after modifications). I can see the benefit of using immutable objects, but in this sense, I can't ever see a useful case for using immutable objects. Is this wrong?

  • Rotate view matrix based on touch coordinates

    - by user1055947
    I'm working on an Android game where I need to rotate the camera around the origin based on the user dragging their finger. My view matrix has initial position of sitting on the negative z and facing origin. I have succeeded in moving the camera through rotation left or right, up or down based on the user dragging the finger, but my problem is obviously that after I drag my finger up/down and rotate say 90 degrees so my intial position of -z is now +y and still facing origin, if I drag my finger left/right I want to rotate from +y to +x, but what happens is it rotates around the pole +y. This is to be expected as I am mapping 2D touch drag coords to 3D space, but I dont know where to start trying to do what I want. Perhaps someone can point me in the right direction, I've been googling for a while now but I don't know what I want to do is called! Edit __ What I was looking for is called an ArcBall, google it for lots of info on it.

  • If I define a property to prototype appears in the constructor of object, why?

    - by Eduard Florinescu
    I took the example from this question modified a bit: What is the point of the prototype method? function employee(name,jobtitle,born) { this.name=name; this.jobtitle=jobtitle; this.born=born; this.status="single" } employee.prototype.salary=10000000; var fred=new employee("Fred Flintstone","Caveman",1970); console.log(fred.salary); fred.salary=20000; console.log(fred.salary) And the output in console is this: What is the difference salary is in constructor but I still can access it with fred.salary, how can I see if is in constructor from code, status is still employee property how can I tell for example if name is the one of employee or has been touch by initialization? Why is salary in constructor, when name,jobtitle,born where "touched" by employee("Fred Flintstone","Caveman",1970); «constructor»?

  • How do you react to non-programmers with ideas of 'The Next Big Thing' ?

    - by jiceo
    Recently and quite often, people with no programming background come and say they have this great idea that can be the next big thing and that the idea(s) is worth a fortune by itself. Then as they know I'm a programmer, they ask me if I'm willing to "code it up" for them or find someone willing to do it for next to nothing. Judging from the enthusiasm, it's like they're drunk on their idea and that that by itself is the most important thing, but they just need a programmer. My response to them, depending on my mood and their general attitude towards what we do, is something along the lines of: "Having the core of an idea is one thing. Developing it to the point that it becomes a platform that changes the world in which it lives is another, and you're going to be willing to pay proportionately to how big you think your idea is worth." Have you been approached by these business type entrepreneurs (with no technical/developer's knowledge) with such a proposal and how do you react to them?

  • DDD: Service or Repository

    - by tikhop
    I am developing an app in DDD manner. And I have a little problem with it. I have a Fare (airline fare) and FareRepository objects. And at some point I should load additional fare information and set this information to existing Fare. I guess that I need to create an Application Service (FareAdditionalInformationService) that will deal with obtaining data from the server and than update existing Fare. However, some people said me that it is necessary to use FareRepository for this problem. I don't know wich place is better for my problem Service or Repository.

  • Why doesn't apache2 respect my envvars file?

    - by Avery Chan
    My envvar files has these lines in it: export APACHE_RUN_USER=www-data export APACHE_RUN_GROUP=www-data My apache2.conf has these lines in it: # These need to be set in /etc/apache2/envvars User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} But when I run apache2 -M I get this: apache2: bad user name ${APACHE_RUN_USER} A temporary fix is to hard-code www-data into it my apache2.conf file. There was some speculation here that this was because some configuration script didn't replace the env vars correctly in my apache2.conf file. Regardless how do I get apache2 to consult my envvars file? As another data point this site seems to indicate the envvars is generated at build, but read by apache2ctl at runtime, suggesting that this file isn't just poop leftover by the build process.

  • Fastest way to get up to speed on webapp development with ASP.NET?

    - by leeand00
    I'm trying to get better at C# ASP.NET 3.5 development (...no none of that MVC stuff :), and fast! My boss gave me a book to read on it from Wrox, but the thing reads like a history novel, telling you how things worked as far back as ASP.NET 1.0; The web application we are developing is completely in ASP.NET 3.5 so I don't need to read through any of the history (maybe I'm wrong about that...but I don't really have the time to read about that...) Do you have any suggestions for a faster (book, series of tutorials) to come up to speed on it? I'd like to learn about UI components, database access, etc... P.S. In a previous position I was an JSP/J2EE developer (and I used MVC all the time! :-D) P.S.S. I did take a course on it in 2008 at some point, but it seemed all very pointy and clickly. I wanna learn the code stuff! The how it works, and where the events are!

  • Screen Corruption in half the screen only

    - by Guy DAmico
    About 50% of the my NATTY desktop screen is corrupted. Once that happens I can re-boot as many times as I want but the problem continues. If I logout and then into WINDOWS for a day I may be successful and boot UBUNTU with a good screen. The desktop is formatted correctly, there's no pixelation, rather there is a fine grained white crosshatch pattern covering the entire screen. If I open any application the screen corruption worsens eventually to the point I can no longer make out anything. I ran ram memory test w/o any errors. I have no display issues when running WINDOWS 7. Any ideas. My computer is a Dual Boot stock DELL 5150 w/3gig of ram an on board video.

  • PeopleSoft at Alliance 2012 Executive Forum

    - by John Webb
    Guest Posting From Rebekah Jackson This week I jointed over 4,800 Higher Ed and Public Sector customers and partners in Nashville at our annual Alliance conference.   I got lost easily in the hallways of the sprawling Gaylord Opryland Hotel. I carried the resort map with me, and I would still stand for several minutes at a very confusing junction, studying the map and the signage on the walls. Hallways led off in many directions, some with elevators going down here and stairs going up there. When I took a wrong turn I would instantly feel stuck, lose my bearings, and occasionally even have to send out a call for help.    It strikes me that the theme for the Executive Forum this year outlines a less tangible but equally disorienting set of challenges that our higher education customer’s CIOs are facing: Making Decisions at the Intersection of Business Value, Strategic Investment, and Enterprise Technology. The forces acting upon higher education institutions today are not neat, straight-forward decision points, where one can glance to the right, glance to the left, and then quickly choose the best course of action. The operational, technological, and strategic factors that must be considered are complex, interrelated, messy…and the stakes are high. Michael Horn, co-author of “Disrupting Class: How Disruptive Innovation Will Change the Way the World Learns”, set the tone for the day. He introduced the model of disruptive innovation, which grew out of the research he and his colleagues have done on ‘Why Successful Organizations Fail’. Highly simplified, the pattern he shared is that things start out decentralized, take a leap to extreme centralization, and then experience progressive decentralization. Using computers as an example, we started with a slide rule, then developed the computer which centralized in the form of mainframes, and gradually decentralized to mini-computers, desktop computers, laptops, and now mobile devices. According to Michael, you have more computing power in your cell phone than existed on the planet 60 years ago, or was on the first rocket that went to the moon. Applying this pattern to Higher Education means the introduction of expensive and prestigious private universities, followed by the advent of state schools, then by community colleges, and now online education. Michael shared statistics that indicate 50% of students will be taking at least one on line course by 2014…and by some measures, that’s already the case today. The implication is that technology moves from being the backbone of the campus, the IT department’s domain, and pushes into the academic core of the institution. Innovative programs are underway at many schools like Bellevue and BYU Idaho, joined by startups and disruptive new players like the Khan Academy.   This presents both threat and opportunity for higher education institutions, and means that IT decisions cannot afford to be disconnected from the institution’s strategic plan. Subsequent sessions explored this theme.    Theo Bosnak, from Attain, discussed the model they use for assessing the complete picture of an institution’s financial health. Compounding the issue are the dramatic trends occurring in technology and the vendors that provide it. Ovum analyst Nicole Engelbert, shared her insights next and suggested that incremental changes are no longer an option, instead fundamental changes are affecting the landscape of enterprise technology in higher ed.    Nicole closed with her recommendation that institutions focus on the trends in higher education with an eye towards the strategic requirements and business value first. Technology then is the enabler.   The last presentation of the day was from Tom Fisher, Sr. Vice President of Cloud Services at Oracle. Tom runs the delivery arm of the Cloud Services group, and shared his thoughts candidly about his experiences with cloud deployments as well as key issues around managing costs and security in cloud deployments. Okay, we’ve covered a lot of ground at this point, from financials planning, business strategy, and cloud computing, with the possibility that half of the institutions in the US might not be around in their current form 10 years from now. Did I forget to mention that was raised in the morning session? Seems a little hard to believe, and yet Michael Horn made a compelling point. Apparently 100 years ago, 8 of the top 10 education institutions in the world were German. Today, the leading German school is ranked somewhere in the 40’s or 50’s. What will the landscape be 100 years from now? Will there be an institution from China, India, or Brazil in the top 10? As Nicole suggested, maybe US parents will be sending their children to schools overseas much sooner, faced with the ever-increasing costs of a US based education. Will corporations begin to view skill-based certification from an online provider as a viable alternative to a 4 year degree from an accredited institution, fundamentally altering the education industry as we know it?

  • Help with creating symbolic link

    - by user1737794
    I'm a little bit confused with how the symbolic links work. I hope someone can guide me in the right direction. I want to put a demo online from our software, which normally only runs locally on a Mac Mini. So I put all the files in the var/www from my Ubuntu 12.04 server installation. There are a lot of hardcoded links in the software which point to "/Applications/XAMPP/xamppfiles/htdocs/narrowcasting" Of course I can change all these code on my html/php files in /var/www, but that would be quite annoying. I hope I can fix this by creating a symbolic link. For example I have a directory called thumb in /var/www/thumb. The php code is trying to put a image in /Applications/XAMPP/xamppfiles/htdocs/narrowcasting/thumb. Can anyone give me a tip how to achieve this with a symbolic link? Thanks in advance.

  • Bad FPS for smaller size (OpenGL ES with SDL)

    - by ber4444
    If you saw my other question, well, there is still a little problem: Click here to watch on youtube Basically, the frame rate is very bad on the actual device, where for some reason the animation is scaled (it looks like the left side on the video). It is quite fast on the simulator where it is not scaled (right side). For a test, I submitted this new changeset that hard-codes the smaller size (plus increases the point size for HII regions to make the dust clouds more visible), and as you see in the video, now it is slow even in the simulator (left side shows the small size, right side shows the original size -- otherwise the code is the same). I'm clueless why it's soooo slow with a smaller galaxy, in fact it should be FASTER. As for general speed optimization (which is not strictly part of my question but is closely related to it, esp. if we need a workaround to speed things up), some initial ideas: reducing the number of items drawn may affect the appearance negatively but screen resolution could be reduced there are too many glBegin(GL_POINTS)/glEnd() blocks, we could draw more than just a single star at once
