• ASP.NET design not SOLID

  - by w0051977

  SOLID principles are described here: http://en.wikipedia.org/wiki/SOLID_%28object-oriented_design%29 I am developing a large ASP.NET app. The previous developer created a few very large classes each with lots of different purposes. It is very difficult to maintain and extend. The classes are deployed to the web server along with the code behind files etc. I want to share a small amount of the app with another application. I am considering moving all of the classes of the ASP.NET web app to a DLL, so the small subset of functionality can be shared. I realise it would be better to only share the classes which contain code to be shared but because of the dependencies this is proving to be very difficult e.g. class A contains code that should be shared, however class A contains references to classes B, C, D, E, F, G etc, so class A cannot be shared on its own. I am planning to refactor the code in the future. As a temporary solution I am planning to convert all the classes into a single class library. Is this a bad idea and if so, is there an alternative? as I don't have time to refactor at the moment.

• How to force Multiple Monitors correct resolutions for LightDM?

  - by Hanynowsky

  I am affected by the BUG: https://bugs.launchpad.net/ubuntu/+source/unity-greeter/+bug/874241 Otherwise, if like me you have a laptop connected to a second monitor of higher resolution, LIGHTDM at the login stage, mirrors the displays in both screens and assign to them a common resolution (1024X768) in my case, instead of extending the desktop (Primary screen with the greeter and secondary with just a logo as mentioned in the Multiple Monitors UX specifications book for 12.04). Here is my xrandr -q @L502X:~$ xrandr -q Screen 0: minimum 320 x 200, current 1920 x 1848, maximum 8192 x 8192 LVDS1 connected 1366x768+309+1080 (normal left inverted right x axis y axis) 344mm x 193mm 1366x768 60.0*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm 1920x1080 60.0*+ 1600x1200 60.0 1680x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1280x800 59.8 1024x768 60.0 800x600 60.3 56.2 640x480 60.0 DP1 disconnected (normal left inverted right x axis y axis) I tried to force lightdm to execute some xrandr commands in order to set the right resolution for each monitor and extend the desktop, but I get a LOW GRAPHICS MODE ERROR (You're running in low graphics mode, your screen, input devices...did not get detected..) I created a simple script named lightdmxrand.sh: #!/bin/sh xrandr --output HDMI1 --primary --mode 1920x1080 --output LVDS1 --mode 1366x768 --below HDMI1 And told lightdm to run it : /etc/lightdm/lightdm.conf [SeatDefaults] greeter-session=unity-greeter user-session=ubuntu greeter-setup-script=/usr/bin/numlockx on display-setup-script=/home/hanynowsky/lightdmxrandr.sh Someone knows what is wrong!?

• WebCenter at Oracle Day Toronto

  - by Lance Shaw

  The Oracle Day event took place in Toronto yesterday at the Hyatt Regency Hotel downtown.  Attendance was excellent and it was standing room only at the keynote sessions.   Anytime the venue has to bring in chairs to handle the overflow crowd, you know there is a lot of interest! This year, WebCenter was featured prominently as part of the Fusion Middleware session track.  What was interesting to see was just how many customers are interested in consolidating and simplifying their existing infrastructure.  So many companies are still struggling with information silos such as file shares, SharePoint Sites and a myriad of departmental or process-centric repositories.  Naturally, these get more and more expensive to manage over time so there is a high level of interest in reducing the size, scope and cost of this infrastructure.  When companies see how they can use Fusion Middleware and related technologies to integrate with WebCenter Content, Imaging and other solutions to centralize content delivery across business applications, they quickly realize that there are significant cost savings to be had. Oracle Day Events are happening all over the world and there is likely going to be one near you.  To check out the full list and to register, visit the Event page here.  It is a great way to not only hear about WebCenter and how it can be used to your advantage, but also a great way to learn about the broader set of related products in the Fusion Middleware portfolio that are available to extend and enhance the power of your particular business solutions. If you cannot make it, or missed the event in your area, be sure to visit our new WebCenter Content page with a variety of informative assets all in one simple location.  It's a new page designed to provide you with easy access to customer stories, videos, whitepapers, webcasts and more.  We hope you find it valuable!

• Entity framework separating entities for product and customer specific implementation

  - by Codecat

  I am designing an application with intention into making it a product line. I would like to extend the functionality across all layers and first struggle is with domain models. For example, core functionality would have entity named Invoice with few standard fields and then customer requirements will add some new fields to it, but I don't want to add to core Invoice class. For every customer I could use customer specific DbContext and injected correct context with dependency injection. Also every customer will get they own deployment public class Product.Domain.Invoice { public int InvoiceId { get; set; } // Other fields } How to approach this problem? Solution 1 does not work since Entity Framework does not allow same simple name classes. public class CustomerA.Domain.Invoice : Product.Domain.Invoice { public User ReviewedBy { get; set; } public DateTime? ReviewedOn { get; set; } } Solution 2 Create separate table and link it to core domain table. Reusing services and controllers could be harder. public class CustomerA.Domain.CustomerAInvoice { public Product.Domain.Invoice Invoice { get; set; } public User ReviewedBy { get; set; } public DateTime? ReviewedOn { get; set; } }

• People != Resources

  - by eddraper

  Ken Tabor’s blog post “They Are not Resources – We Are People” struck a chord with me.  I distinctly remember hearing the term “resources” within the context of “people” for the first time back in the late 90’s.  I was in a meeting at Compaq and a manager had been faced with some new scope for an IT project he was managing.  His response was that he needed more “resources” in order to get the job done.  As I knew the timeline for the project was fixed and the process for acquiring additional funding would almost certainly extend beyond his expected delivery date, I wondered what he meant.  After the meeting, I asked him what he meant… his response was that he needed some more “bodies” to get the job done.  For a minute, my mind whirred… why is it so difficult to simply say “people?”  This particular manager was neither a bad person nor a bad manager… quite the contrary.  I respected him quite a bit and still do.  Over time, I began to notice that he was what could be termed an “early adopter” of many “Business speak” terms – such as “sooner rather than later,” “thrown a curve,” “boil the ocean” etcetera.  Over time, I’ve discovered that much of this lexicon can actually be useful, though cliché and overused.  For example, “Boil the ocean” does serve a useful purpose in distilling a lot of verbiage and meaning into three simple words that paint a clear mental picture.  The term “resources” would serve a similar purpose if it were applied to the concept of time, funding, or people.  The problem is that this never happened.  “Resources”, “bodies”, “ICs” (individual contributors)… this is what “people” have become in the IT business world.  Why?  We’re talking about simple word choices here.  Why have human beings been deliberately dehumanized and abstracted in this manner? What useful purpose does it serve other than to demean and denigrate?

• When is it ever ok to write your own development tools? (editor into IDE)

  - by mario

  So I'm foremost using a text editor for coding. It's a very bare bones editor; provides mostly just syntax highlighting. But on rare occasions I also need to debug something. And that's when I have to resort to an IDE (mostly Netbeans, but got fiddly Eclipse/Aptana working as second fallback). For general use however IDEs feel not workable to me. It's a visual thing, being used to console UIs etc. And switching back and forth between a text editor and an IDE is slightly cumbersome too. That's why I'm considering extending the editor, not really into a full-fledged IDE - but at the very least integrate a debug feature. Since I'm working on PHP, it seems not that much effort. The DBGp allows to externalize a debug handler from the editor, so it's just minor integration work and figuring out how to shoehorn a breakpoint feature into the editor (joe btw). And while I've also got time to do that, I'm wondering if this is really worthwhile. In this case it's not a needed development tool. It's just for convenience. And the cause for doing it is basically just not liking the existing solution. While over time I might extend and adapt this debugger thing, it initially will be as circumstantial as Eclipse. It inevitably starts out as poor development tool. Furthermore there is likely not much reuse. (Okay, this is not an important point. Most such software exists sans much of a use case. And also obviously, similar extensions already exist for emacs and vim, so it cannot be completely pointless.) But what's a general guideline on attempting to conoct custom development tools, particularily if they are not really needed but satisfy personal preferences? (Usability enhancement not certain.)

• Best practice for combining a Java Applet/ Android interface?

  - by Pearsonartphoto

  I'm working on an online game, which I am seriously considering writing a Java Applet for it. The game is not overly complex on the features. I'm considering at some point having at least 3 versions of the game, which include a Java stand alone, applet, and Android game. I know from Design Patterns that the best way to use differing things like buttons and the like is to use a Bridge interface, where I have a common template for the common buttons. However, I'm having a bit of difficulty understanding what to do about the following. I know that Android programs use an Activity structure, which I am well familiar with, and that Applets extend the Applet interface, which I am not as familiar with. I also know that a stand alone java program uses basically a main() function, which doesn't have much structure. I'm convinced that there should be a way to design a common design pattern between the two, but somehow I'm missing what that is exactly. What can I do to make the different frameworks work with as much common code as possible?

• What's wrong with circular references?

  - by dash-tom-bang

  I was involved in a programming discussion today where I made some statements that basically assumed axiomatically that circular references (between modules, classes, whatever) are generally bad. Once I got through with my pitch, my coworker asked, "what's wrong with circular references?" I've got strong feelings on this, but it's hard for me to verbalize concisely and concretely. Any explanation that I may come up with tends to rely on other items that I too consider axioms ("can't use in isolation, so can't test", "unknown/undefined behavior as state mutates in the participating objects", etc.), but I'd love to hear a concise reason for why circular references are bad that don't take the kinds of leaps of faith that my own brain does, having spent many hours over the years untangling them to understand, fix, and extend various bits of code. Edit: I am not asking about homogenous circular references, like those in a doubly-linked list or pointer-to-parent. This question is really asking about "larger scope" circular references, like libA calling libB which calls back to libA. Substitute 'module' for 'lib' if you like. Thanks for all of the answers so far!

• How can I design my classes to include calendar events stored in a database?

  - by Gianluca78

  I'm developing a web calendar in php (using Symfony2) inspired by iCal for a project of mine. At this moment, I have two classes: a class "Calendar" and a class "CalendarCell". Here you are the two classes properties and method declarations. class Calendar { private $month; private $monthName; private $year; private $calendarCellList = array(); private $translator; public function __construct($month, $year, $translator) {} public function getCalendarCellList() {} public function getMonth() {} public function getMonthName() {} public function getNextMonth() {} public function getNextYear() {} public function getPreviousMonth() {} public function getPreviousYear() {} public function getYear() {} private function calculateDaysPreviousMonth() {} private function calculateNumericDayOfTheFirstDayOfTheWeek() {} private function isCurrentDay(\DateTime $dateTime) {} private function isDifferentMonth(\DateTime $dateTime) {} } class CalendarCell { private $day; private $month; private $dayNameAbbreviation; private $numericDayOfTheWeek; private $isCurrentDay; private $isDifferentMonth; private $translator; public function __construct(array $parameters) {} public function getDay() {} public function getMonth() {} public function getDayNameAbbreviation() {} public function isCurrentDay() {} public function isDifferentMonth() {} } Each calendar day can includes many calendar events (such as appointments or schedules) stored in a database. My question is: which is the best way to manage these calendar events in my classes? I think to add a eventList property in CalendarCell and populate it with an array of CalendarEvent objects fetched by the database. This kind of solution doesn't allow other coders to reuse the classes without db (because I should inject at least a repository services also) just to create and visualize a calendar... so maybe it could be better to extend CalendarCell (for instance in CalendarCellEvent) and add the database features? I feel like I'm missing some crucial design pattern! Any suggestion will be very appreciated!

• Should business services cross bounded contexts?

  - by Paul T Davies

  Firstly, I am following the convention that a bounded context is synonymous to a department, or possibly one department has 1 to many bounded contexts. We have a client consultancy department that has a Documentation Service. Documents are stored in the Document Store Service (which is where all documents in the company are stored - it is a utility service), and the Documentation Service stores information about that document (a business service). As it was designed for the client consultancy, it is information relevant to them. Now health and safety need somewhere to store information about a document. This is different information to client consultancy, but I have been instructed to extend the existing service to account for this extra information. I feel this service is now crossing a bounded context. My worry is that all departments will eventually store there information in here and the service will become bloated, trying to be all things to all departments. Each document record will only store a subset of the information because it will only belong to one department. It will get worse when different departments want to store the same information but refer to it in a diferent ways, or when two departments want to store different information that they refer to in the same way. In my understanding, this is exactly the reason for bounded contexts. I feel each department should have it's own business service for information about a document, but use the same utility service to actually store the document. What would be the correct approach?

• Artists and music - i need help to decide wich cms to use.

  - by infty

  A friend has asked me to build a site with the following options: staff members must be able to add new music and artists to the page a gallery must be provided - it is also good if each artist has the ability to have his/her own, smaller, gallery users must be able to vote for artists users must be able to alter in discussions (forums or comments sections) staff members must be able to blog staff members must be able to write articles I did a small project where i actually implementet all of these features, but i want to use an existing content managment system for all of these features so that future devolpers can, hopefully, more easy extend the website. And also, so that i dont have to provide to much documentation. I have never developed a website using an external cms like drupal or wordpress and after seeing hours of tutorial videos of both systems, i still cant make up my mind on wheter i should : a) use Drupal 7 b) use Wordpress 3 c) create my own cms I can only imagine that staff members would also want to create content using iphone or android based mobile devices. But this is not a required feature. Can someone, with experience, please tell me about their experiences with bigger projects like this? The site will approx. have a total of 400 000 - 500 000 visitors (not daily visitors, based on numbers from last year in a period of 4 months)

• Cookie access within a HTTP Class

  - by James Jeffery

  I have a HTTP class that has a Get, and Post, method. It's a simple class I created to encapsulate Post and Get requests so I don't have to repeat the get/post code throughout the application. In C#: class HTTP { private CookieContainer cookieJar; private String userAgent = "..."; public HTTP() { this.cookieJar = new CookieContainer(); } public String get(String url) { // Make get request. Return the JSON } public String post(String url, String postData) { // Make post request. Return the JSON } } I've made the CookieJar a property because I want to preserve the cookie values throughout the session. If the user is logged into Twitter with my application, each request I make (be it get or post) I want to use the cookies so they remain logged in. That's the basics of it anyway. But, I don't want to return a string in all instances. Sometimes I may want the cookie, or a header value, or something else from the request. Ideally I'd like to be able to do this in my code: Cookie cookie = http.get("http://google.com").cookie("g_user"); String g_user = cookie.value; or String source = http.get("http://google.com").body; My question - To do this, would I need to have a Get class, and a Post class, that are included within the HTTP class and are accessible via accessors? Within the Get and Post class I would then have the Cookie method, and the body property, and whatever else is needed. Should I also use an interface, or create a Request class and have Post and Get extend it so that common methods and properties are available to both classes? Or, am I thinking totally wrong?

• Dynamic Query Generation : suggestion for better approaches

  - by Gaurav Parmar

  I am currently designing a functionality in my Web Application where the verified user of the application can execute queries which he wishes to from the predefined set of queries with where clause varying as per user's choice. For example,Table ABC contains the following Template query called SecretReport "Select def as FOO, ghi as BAR from MNO where " SecretReport can have parameters XYZ, ILP. Again XYZ can have values as 1,2 and ILP can have 3,4 so if the user chooses ILP=3, he will get the result of the following query on his screen "Select def as FOO, ghi as BAR from MNO where ILP=3" Again the user is allowed permutations of XYZ / ILP My initial thought is that User will be shown a list of Report names and each report will have parameters and corresponding values. But this approach although technically simple does not appear intuitive. I would like to extend this functionality to a more generic level. Such that the user can choose a table and query based on his requirements. Of course we do not want the end user to take complete control of DB. But only tables and fields that are relevant to him. At present we are defining what is relevant in the code. But I want the Admin to take over this functionality such that he can decide what is relevant and expose the same to the user. On user's side it should be intuitive what is available to him and what queries he can form. Please share your thoughts what is the most user friendly way to provide this feature to the end user.

• I don't program in my spare time. Does that make me a bad developer?

  - by not-my-real-name

  A lot of blogs and advice on the web seem to suggest that in order to become a great developer, doing just your day job is not enough. For example, you should contribute to open source projects in your spare time, write smartphone apps, etc. In fact a lot of this advice seems to suggest that if you don't love programming enough to do it all day long then you're probably in the wrong career. That doesn't ring true with me. I enjoy my work, but when I come home from the office I'm not in the mood to jump straight back onto the computer and start coding away until bedtime. I only have a certain number of hours free time each day, and I'd rather spend them on other hobbies, seeing friends or going outside than in front of the computer. I do get a kick out of programming, and do hack around outside of work occasionally. I'm committed to my personal development and spend time reading tech blogs and books as a way to keep learning and becoming better. But that doesn't extend so far as to my wanting to use all my spare time for coding. Does this mean I'm not a 'true' software developer at heart? Is it possible to become a good software developer without doing extra outside your job? I'd be very interested to hear what you think.

• UDK - How to make sure a PhysicalMaterial mask actually works?

  - by tomacmuni

  Hello, I have been reading the documentation for UDK about physical materials and masks. I have my 1bit BMP mask, and the two physical material assets I want to shoot off in the black and white channels. I have applied my material to both a rigid body and to a skeletal mesh and neither apparently uses the mask. If I assign a regular physical material (one that doesn't use a mask) then it will work fine, but this defeats the point because it gives only one hit reaction. In the documentation it states that it is possible to extend a class on which we want to use a physical material based on the KActor class's usage. How to do that? Here is the quote: "The following properties [ie, ImpactEffect - Particle system to spawn at the point of impact + ImpactSound - Sound to play when an impact occurs] allow you to attach sounds and effects to physical collisions. These only work on classes which support them, which at the moment is only KActor. By looking at the implementation in KActor though, you can add this functionality to other classes (or you can subclass KActor)." Essentially, how to make sure a PhysicalMaterial mask actually works? What code could be added to a skeletal mesh class perhaps, to get it going? Any help appreciated.

• Preferred way for dealing with customer-defined data in enterprise application

  - by Axarydax

  Let's say that we have a small enterprise web (intranet) application for managing data for car dealers. It has screens for managing customers, inventory, orders, warranties and workshops. This application is installed at 10 customer sites for different car dealers. First version of this application was created without any way to provide for customer-specific data. For example, if dealer A wanted to be able to attach a photo to a customer, dealer B wanted to add e-mail contact to each workshop, and dealer C wanted to attach multiple PDF reports to a warranty, each and every feature like this was added to the application, so all of the customers received everything on new update. However, this will inevitably lead to conflicts as the number of customers grow as their usage patterns are unique, and if, for instance, a specific dealer requested to have an ability to attach (for some reason) a color of inventory item (and be able to search by this color) as a required item, others really wouldn't need this feature, and definitely will not want it to be a required item. Or, one dealer would like to manage e-mail contacts for their employees on a separate screen of the application. I imagine that a solution for this is to use a kind of plugin system, where we would have a core of the application that provides for standard features like customers, inventory, etc, and all of the customer's installed plugins. There would be different kinds of plugins - standalone screens like e-mail contacts for employees, with their own logic, and customer plugin which would extend or decorate inventory items (like photo or color). Inventory (customer,order,...) plugins would require to have installation procedure, hooks for plugging into the item editor, item displayer, item filtering for searching, backup hook and such. Is this the right way to solve this problem?

• At the Java DEMOgrounds - ZeroTurnaround and its LiveRebel 2.5

  - by Janice J. Heiss

  At the ZeroTurnaround demo, I spoke with Krishnan Badrinarayanan, their Product Marketing Manager. ZeroTurnaround, the creator of JRebel and LiveRebel, describes itself on their site as a company “dedicated to changing the way the world develops, tests and runs Java applications."“We just launched LiveRebel 2.5 today,” stated Badrinarayanan, “which enables companies to embrace the concept and practice of continuous delivery, which means having a pipeline that takes products right from the developers to an end-user, faster, more frequently -- all the while ensuring that it’s a quality product that does not break in production. So customers don’t feel the discontinuity that something has changed under them and that they can’t deal with the change. And all this happens while there is zero down time.”He pointed out that Salesforce.com is not useable from 3 a.m. to 5 a.m. on Saturday because they are engaged in maintenance. “With LiveRebel 2.5, you can unify the whole delivery chain without having any downtime at all,” he said. “There are many products that tell customers to take their tools and change how they work as an organization so that you they have to conform to the way the tool prescribes them to work as an application team. We take a more pragmatic approach. A lot of companies might use Jenkins or Bamboo to do continuous integration. We extend that. We say, take our product, take LiveRebel okay, and integrate it with Jenkins – you can do that quickly, so that, in half a day, you will be up and running. And let LiveRebel automate your deployment processes and all the automated tasks that go with it. Right from tests to the staging environment to production -- all with zero downtime and with no impact on users currently using the system.” “So if you were to make the update right now and you had 100 users on your system, they would not even know this was happening. It would maintain their sessions and transfer them over to the new version, all in the background.”

• Game planning and software design? I feel that UML is not convenient

  - by user1542

  In my university, they always emphasize and hype about UML design and stuff, in which I feel it is not going to work well with game structure design. Now, I just want a professional advice on how should I begin my game designing? The story is I have some skill in programming and have done many minor game such as getting some 2D platformer working to some extend. The problems that I find about my program is the poor quality design. After coding for a while, things start to break down due to poor planning (When I add new feature, it tends to make me have to recode the whole program). However, to plan everything out without a single design flaw is a bit too ideal. Therefore, any advice to how should I plan my game? How should I put it into visible pictures, so that me and my friends are able to overview the designs? I planned to start coding a game with my friend. This is going to be my first teamwork, so any professional advices would be a pleasure. Is there any other alternatives than UML? Another question is how does "prototyping" normally looks like?

The site will have approximately 400 000 - 500 000 visitors (not daily visitors, based on numbers from last year in a period of 4 months)

• JSR 308 Moves Forward

  - by abuckley

  I am pleased to announce a number of recent milestones for JSR 308, Annotations on Java Types: Adoption of JCP 2.8 Thanks to the agreement of the Expert Group, JSR 308 operates under JCP 2.8 from September 2012. There is a publicly archived mailing list for EG members, and a companion list for anyone who wishes to follow EG traffic by email. There is also a "suggestion box" mailing list where anyone can send feedback to the E.G. directly. Feedback will be discussed on the main EG list. Co-spec lead Prof. Michael Ernst maintains an issue tracker and a document archive. Early-Access Builds of the Reference Implementation Oracle has published binaries for all platforms of JDK 8 with support for type annotations. Builds are generated from OpenJDK's type-annotations/type-annotations forest (notably the langtools repo). The forest is owned by the Type Annotations project. Integration with Enhanced Metadata On the enhanced metadata mailing list, Oracle has proposed support for repeating annotations in the Java language in Java SE 8. For completeness, it must be possible to repeat annotations on types, not only on declarations. The implementation of repeating annotations on declarations is already in the type-annotations/type-annotations forest (and hence in the early-access builds above) and work is underway to extend it to types.

• REST API wrapper - class design for 'lite' object responses

  - by sasfrog

  I am writing a class library to serve as a managed .NET wrapper over a REST API. I'm very new to OOP, and this task is an ideal opportunity for me to learn some OOP concepts in a real-life situation that makes sense to me. Some of the key resources/objects that the API returns are returned with different levels of detail depending on whether the request is for a single instance, a list, or part of a "search all resources" response. This is obviously a good design for the REST API itself, so that full objects aren't returned (thus increasing the size of the response and therefore the time taken to respond) unless they're needed. So, to be clear: .../car/1234.json returns the full Car object for 1234, all its properties like colour, make, model, year, engine_size, etc. Let's call this full. .../cars.json returns a list of Car objects, but only with a subset of the properties returned by .../car/1234.json. Let's call this lite. ...search.json returns, among other things, a list of car objects, but with minimal properties (only ID, make and model). Let's call this lite-lite. I want to know what the pros and cons of each of the following possible designs are, and whether there is a better design that I haven't covered: Create a Car class that models the lite-lite properties, and then have each of the more detailed responses inherit and extend this class. Create separate CarFull, CarLite and CarLiteLite classes corresponding to each of the responses. Create a single Car class that contains (nullable?) properties for the full response, and create constructors for each of the responses which populate it to the extent possible (and maybe include a property that returns the response type from which the instance was created). I expect among other things there will be use cases for consumers of the wrapper where they will want to iterate through lists of Cars, regardless of which response type they were created from, such that the three response types can contribute to the same list. Happy to be pointed to good resources on this sort of thing, and/or even told the name of the concept I'm describing so I can better target my research.

• Generic Pop and Push for List<T>

  - by Bil Simser

  Here's a little snippet I use to extend a generic List class to have similar capabilites to the Stack class. The Stack<T> class is great but it lives in its own world under System.Object. Wouldn't it be nice to have a List<T> that could do the same? Here's the code: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public static class ExtensionMethods 2: { 3: public static T Pop<T>(this List<T> theList) 4: { 5: var local = theList[theList.Count - 1]; 6: theList.RemoveAt(theList.Count - 1); 7: return local; 8: } 9:   10: public static void Push<T>(this List<T> theList, T item) 11: { 12: theList.Add(item); 13: } 14: } It's a simple extension but I've found it useful, hopefully you will too! Enjoy.

• Building an intranet

  - by WernerCD

  I'm researching for a project I'm going to be doing at work on the side... I work for a small hospital and we recently upgraded all the browsers inside our intranet to IE8 (Goodbye 6 :). We have a small, obsolete intranet built by someone who isn't a web designer... functional enough, but annoying to maintain and really sparse. What I'm wanting to do... is use a good framework. I'm looking for suggestions... I'm looking for something Windows IIS based. I'd love windows authentication - with the ability to delegate sub-sections of the website to managers. Right now it's my job to add/update/delete anything from the site... I'd like something not complicated that can be delegated to non-technical people. Like... the Cafeteria Manager should be able to update the menu without putting a ticket into me. She'd log into her computer, open the intranet (which would use her windows log-on to identify her) and have elevated privileges to edit her section of the intranet. If I have to "extend" a good framework to get Windows Authentication, I'll do it... but I'd prefer it to be baked in. What are some good frameworks, tools and places to start? While this isn't a "Huge" project... it's going to be bigger than the basic stuff I've done before and I'd like a good place to start.
