  • Personal Development : Time, Planning , Repairs & Maintenance

    - by Rajesh Pillai
    Personal Development : Time, Planning, Repairs & Maintenance These are just my thoughts, but some you may find something interesting in it. Please think over it. We may know many things, but still we always keeps procrastinating it. I have written this as I have heard many people coming back and saying they don’t have time to do things they like. These are my thoughts buy may be useful to someone else too. Certain things in life needs periodic repairs and maintenance. To cite some examples , your CAR, your HOUSE, your personal laptop/desktop, your health etc. Likewise there are certain other things in professional life that requires repair/ maintenance /or some kind of polishing, so that you always stay on top of it. But they are not always obvious. Some of them are - Improving your communication skills - Increasing your vocabulary - Upgrading your technical skills - Pursuing your hobby - Increasing your knowledge/awareness etc… etc… And then there are certain things that we are always short of…. one is TIME. We all know TIME is one of the most precious things in life and yet we all are very miserable at managing it. Remember you can only manage it and not control it. You can only control which you own or which you create. In theory time is infinite. So, there should be abundant of it. But remember one thing, you know this, it’s not reversible. Once it has elapsed you cannot live it again. Think over it. So, how do find that golden 25th hour every day. To find the 25th hour you need to reflect back on your current daily activities. Analyze them and see where you are spending most of your time and is it really important. Even the 8 hours that you spent in the office, is it spent fruitfully. At the end of the day is the 8 precious hour that you spent was worth it. Just reflect back on your activities. Did you learn something? If yes did you make a point to NOTE IT. If you didn’t NOTED it then was the time you spent really worth it. Just ponder over it. Some calculations of your daily activities where most of the time is spent. Let’s start (in no particular order though) - Sleep (6.5 hours) [Remember you only require 6 good hours of sleep every day]. Some may thing it is 8, but it’s a myth.   o To achive 6 hours of sleep and be in good health you can practice 15 minutes of daily meditation. So effectively you can    round it to 6.5 hours. - Morning chores(2 hours) : Some may need to prepare breakfast and all other things. - Office commuting (avg. to and fro 3 hours) - Office Work (avg 9.5 hours) Total Hours: 21 hours effective time which is spent irrespective of what you do. There may be some variations here and there. Still you have 3 hours EXTRA. Where do these 3 hours go? If you can find it, then you may get that golden 25th hour out of these 3 hours. Let’s discount 2 hours for contingencies, still you have 1 hour with you. If you can’t find it then you are living a direction less life. As you can see, the 25th Hour lies within the 24 hours of the day. It’s upto each one of us to find and make use of it. Now what can you do with that 25th hour i.e. 1 hour extra of your life. Imagine the possibility. Again some calculations 1 hour daily * 30 days = 30 hours every month 30 hours pm * 12 month = 360 hours every year. 360 hours every year seems very promising. Let’s add some contingencies, say, let’s be optimistic and say 50 % contingency. Still you have 180 hours every year. That leaves with 30 minutes every day of extra time. That’s hell a lot of time, if you could manage it. These may sound like a high talk [yes, it is, unless you apply these simple rules and rationalize your everyday living and stop procrastinating]. NOTE: I haven’t taken weekend, holidays and leaves into account. So, that leaves us with a lot of buffer time. You can meet family friends, relatives, other tasks, and yet have these 180 pure hours of joy every year. Do whatever you want to do with it. So, how important is this 180 hours per year to you? Just think over it. You may use it the way you like - 50 hours [pursue your hobby like drawing, crafting, learn dance, learn juggling, learn swimming, travelling hmm.. anything you like doing and you didn’t had time to do it.] - 30 hours you can learn a new programming language or technology (i.e. you can get comfortable with it) - 50 hours [improve existing skills] - 20 hours [improve you communication skill]. Do some light reading. - 30 hours [YOU DECIDE WHAT TO DO]? So, if you had done this for one year you would have learnt a new programming language, upgraded existing skills, improved you communication etc.. If you had done this for two years.. imagine the level of personal development or growth which you may have attained….. If you had done this for three years….. NOW I think I don’t need to mention this… So, you still have TIME, as they say TIME is infinite. So, make judicious use of this precious thing. And never ever comeback saying “I don’t have time”. So, if you are RICH in TIME, everything else will be automatically taken care of, as those things may just be a byproduct of how you spend your time… So, happy TIMING your TIME everyday.

  • Mathemagics - 3 consecutive number

    - by PointsToShare
    © 2011 By: Dov Trietsch. All rights reserved Three Consecutive numbers When I was young and handsome (OK, OK, just young), my father used to challenge us with riddles and tricks involving Logic, Math and general knowledge. Most of the time, at least after reaching the ripe age of 10, I would see thru his tricks in no time. This one is a bit more subtle. I had to think about it for close to an hour and then when I had the ‘AHA!’ effect, I could not understand why it had taken me so long. So here it is. You select a volunteer from the audience (or a shill, but that would be cheating!) and ask him to select three consecutive numbers, all of them 1 or 2 digits. So {1, 2, 3} would be good, albeit trivial set, as would {8, 9, 10} or {97, 98, 99} but not {99, 99, 100} (why?!). Now, using a calculator – and these days almost every phone has a built in calculator – he is to perform these steps: 1.      Select a single digit 2.      Multiply it by 3 and write it down 3.      Add the 3 consecutive numbers 4.      Add the number from step 2 5.      Multiply the sum by 67 6.      Now tell me the last 2 digits of the result and also the number you wrote down in step 2 I will tell you which numbers you selected. How do I do this? I’ll give you the mechanical answer, but because I like you to have the pleasure of an ‘AHA!’ effect, I will not really explain the ‘why’. So let’s you selected 30, 31, and 32 and also that your 3 multiple was 24, so here is what you get 30 + 31 + 32 = 93 93 + 24 = 117 117 x 67 = 7839, last 2 digits are 39, so you say “the last 2 digits are 39, and the other number is 24.” Now, I divide 24 by 3 getting 8. I subtract 8 from 39 and get 31. I then subtract 1 from this getting 30, and say: “You selected 30, 31, and 32.” This is the ‘how’. I leave the ‘why’ to you! That’s all folks! PS do you really want to know why? Post a feedback below. When 11 people or more will have asked for it, I’ll add a link to the full explanation.

  • Donald Farmer left Microsoft for QlikView

    - by Marco Russo (SQLBI)
    As many of you probably already know, Donald Farmer left Microsoft to join QlikView . There are no doubts that Donald have been “the face of Microsoft BI” in the last years. This news has been initially perceived (me included, I admit) as a possible lack of confidence in Microsoft BI Vision, but after reading his blog and many other comments from Microsoft people, I can say it is not. This is more a personal choice, looking for a new challenge in a brilliant career in a relatively smaller environment...(read more)

  • Should I register the domain name that has not popular top level domain name

    - by sreginogemoh
    Lets say for example you want to register domain name assembly.com or assembly.net and find out that they are already registered(not available). Would you go with the domain name assemb.ly in such case? By having .ly the domain name represent word assembly but I think .ly domain is not so friendly for search engines? What do you think? Do you see any advantage of asemb.ly over assembly.com or assembly.net except it is shorter?

  • Microsoft Dev Centre accounts

    - by Phil Murray
    Looks like Microsoft is offering a special offer of 95% of the yearly subscription for the Phone Dev Centre (I didn't say anything about desperate). What I was wondering is do you need a seperate account to publish to the Windows Phone app centre and the Windows App Centre? Also I heard some horror stories about the time it takes to get application published on the Windows phone marketplace, does anyone have any experience with this?

  • Using virtual functions

    - by Tucker Morgan
    I am starting to use virtual functions, and i am programming a simple text game, my question is this, if i have a virtual function called spec_abil with in a Super class called rpg_class. If you allow the player to class what class they want to play, say a mage class, a archer class, and a warrior class, which all have their own spec_abil function. How do you write it so that the program knows which one to use depending on the chosen class.

  • How accurate is "Business logic should be in a service, not in a model"?

    - by Jeroen Vannevel
    Situation Earlier this evening I gave an answer to a question on StackOverflow. The question: Editing of an existing object should be done in repository layer or in service? For example if I have a User that has debt. I want to change his debt. Should I do it in UserRepository or in service for example BuyingService by getting an object, editing it and saving it ? My answer: You should leave the responsibility of mutating an object to that same object and use the repository to retrieve this object. Example situation: class User { private int debt; // debt in cents private string name; // getters public void makePayment(int cents){ debt -= cents; } } class UserRepository { public User GetUserByName(string name){ // Get appropriate user from database } } A comment I received: Business logic should really be in a service. Not in a model. What does the internet say? So, this got me searching since I've never really (consciously) used a service layer. I started reading up on the Service Layer pattern and the Unit Of Work pattern but so far I can't say I'm convinced a service layer has to be used. Take for example this article by Martin Fowler on the anti-pattern of an Anemic Domain Model: There are objects, many named after the nouns in the domain space, and these objects are connected with the rich relationships and structure that true domain models have. The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects, making them little more than bags of getters and setters. Indeed often these models come with design rules that say that you are not to put any domain logic in the the domain objects. Instead there are a set of service objects which capture all the domain logic. These services live on top of the domain model and use the domain model for data. (...) The logic that should be in a domain object is domain logic - validations, calculations, business rules - whatever you like to call it. To me, this seemed exactly what the situation was about: I advocated the manipulation of an object's data by introducing methods inside that class that do just that. However I realize that this should be a given either way, and it probably has more to do with how these methods are invoked (using a repository). I also had the feeling that in that article (see below), a Service Layer is more considered as a façade that delegates work to the underlying model, than an actual work-intensive layer. Application Layer [his name for Service Layer]: Defines the jobs the software is supposed to do and directs the expressive domain objects to work out problems. The tasks this layer is responsible for are meaningful to the business or necessary for interaction with the application layers of other systems. This layer is kept thin. It does not contain business rules or knowledge, but only coordinates tasks and delegates work to collaborations of domain objects in the next layer down. It does not have state reflecting the business situation, but it can have state that reflects the progress of a task for the user or the program. Which is reinforced here: Service interfaces. Services expose a service interface to which all inbound messages are sent. You can think of a service interface as a façade that exposes the business logic implemented in the application (typically, logic in the business layer) to potential consumers. And here: The service layer should be devoid of any application or business logic and should focus primarily on a few concerns. It should wrap Business Layer calls, translate your Domain in a common language that your clients can understand, and handle the communication medium between server and requesting client. This is a serious contrast to other resources that talk about the Service Layer: The service layer should consist of classes with methods that are units of work with actions that belong in the same transaction. Or the second answer to a question I've already linked: At some point, your application will want some business logic. Also, you might want to validate the input to make sure that there isn't something evil or nonperforming being requested. This logic belongs in your service layer. "Solution"? Following the guidelines in this answer, I came up with the following approach that uses a Service Layer: class UserController : Controller { private UserService _userService; public UserController(UserService userService){ _userService = userService; } public ActionResult MakeHimPay(string username, int amount) { _userService.MakeHimPay(username, amount); return RedirectToAction("ShowUserOverview"); } public ActionResult ShowUserOverview() { return View(); } } class UserService { private IUserRepository _userRepository; public UserService(IUserRepository userRepository) { _userRepository = userRepository; } public void MakeHimPay(username, amount) { _userRepository.GetUserByName(username).makePayment(amount); } } class UserRepository { public User GetUserByName(string name){ // Get appropriate user from database } } class User { private int debt; // debt in cents private string name; // getters public void makePayment(int cents){ debt -= cents; } } Conclusion All together not much has changed here: code from the controller has moved to the service layer (which is a good thing, so there is an upside to this approach). However this doesn't look like it had anything to do with my original answer. I realize design patterns are guidelines, not rules set in stone to be implemented whenever possible. Yet I have not found a definitive explanation of the service layer and how it should be regarded. Is it a means to simply extract logic from the controller and put it inside a service instead? Is it supposed to form a contract between the controller and the domain? Should there be a layer between the domain and the service layer? And, last but not least: following the original comment Business logic should really be in a service. Not in a model. Is this correct? How would I introduce my business logic in a service instead of the model?

  • Movement prediction for non-shooters

    - by ShadowChaser
    I'm working on an isometric 2D game with moderate-scale multiplayer, approximately 20-30 players connected at once to a persistent server. I've had some difficulty getting a good movement prediction implementation in place. Physics/Movement The game doesn't have a true physics implementation, but uses the basic principles to implement movement. Rather than continually polling input, state changes (ie/ mouse down/up/move events) are used to change the state of the character entity the player is controlling. The player's direction (ie/ north-east) is combined with a constant speed and turned into a true 3D vector - the entity's velocity. In the main game loop, "Update" is called before "Draw". The update logic triggers a "physics update task" that tracks all entities with a non-zero velocity uses very basic integration to change the entities position. For example: entity.Position += entity.Velocity.Scale(ElapsedTime.Seconds) (where "Seconds" is a floating point value, but the same approach would work for millisecond integer values). The key point is that no interpolation is used for movement - the rudimentary physics engine has no concept of a "previous state" or "current state", only a position and velocity. State Change and Update Packets When the velocity of the character entity the player is controlling changes, a "move avatar" packet is sent to the server containing the entity's action type (stand, walk, run), direction (north-east), and current position. This is different from how 3D first person games work. In a 3D game the velocity (direction) can change frame to frame as the player moves around. Sending every state change would effectively transmit a packet per frame, which would be too expensive. Instead, 3D games seem to ignore state changes and send "state update" packets on a fixed interval - say, every 80-150ms. Since speed and direction updates occur much less frequently in my game, I can get away with sending every state change. Although all of the physics simulations occur at the same speed and are deterministic, latency is still an issue. For that reason, I send out routine position update packets (similar to a 3D game) but much less frequently - right now every 250ms, but I suspect with good prediction I can easily boost it towards 500ms. The biggest problem is that I've now deviated from the norm - all other documentation, guides, and samples online send routine updates and interpolate between the two states. It seems incompatible with my architecture, and I need to come up with a better movement prediction algorithm that is closer to a (very basic) "networked physics" architecture. The server then receives the packet and determines the players speed from it's movement type based on a script (Is the player able to run? Get the player's running speed). Once it has the speed, it combines it with the direction to get a vector - the entity's velocity. Some cheat detection and basic validation occurs, and the entity on the server side is updated with the current velocity, direction, and position. Basic throttling is also performed to prevent players from flooding the server with movement requests. After updating its own entity, the server broadcasts an "avatar position update" packet to all other players within range. The position update packet is used to update the client side physics simulations (world state) of the remote clients and perform prediction and lag compensation. Prediction and Lag Compensation As mentioned above, clients are authoritative for their own position. Except in cases of cheating or anomalies, the client's avatar will never be repositioned by the server. No extrapolation ("move now and correct later") is required for the client's avatar - what the player sees is correct. However, some sort of extrapolation or interpolation is required for all remote entities that are moving. Some sort of prediction and/or lag-compensation is clearly required within the client's local simulation / physics engine. Problems I've been struggling with various algorithms, and have a number of questions and problems: Should I be extrapolating, interpolating, or both? My "gut feeling" is that I should be using pure extrapolation based on velocity. State change is received by the client, client computes a "predicted" velocity that compensates for lag, and the regular physics system does the rest. However, it feels at odds to all other sample code and articles - they all seem to store a number of states and perform interpolation without a physics engine. When a packet arrives, I've tried interpolating the packet's position with the packet's velocity over a fixed time period (say, 200ms). I then take the difference between the interpolated position and the current "error" position to compute a new vector and place that on the entity instead of the velocity that was sent. However, the assumption is that another packet will arrive in that time interval, and it's incredibly difficult to "guess" when the next packet will arrive - especially since they don't all arrive on fixed intervals (ie/ state changes as well). Is the concept fundamentally flawed, or is it correct but needs some fixes / adjustments? What happens when a remote player stops? I can immediately stop the entity, but it will be positioned in the "wrong" spot until it moves again. If I estimate a vector or try to interpolate, I have an issue because I don't store the previous state - the physics engine has no way to say "you need to stop after you reach position X". It simply understands a velocity, nothing more complex. I'm reluctant to add the "packet movement state" information to the entities or physics engine, since it violates basic design principles and bleeds network code across the rest of the game engine. What should happen when entities collide? There are three scenarios - the controlling player collides locally, two entities collide on the server during a position update, or a remote entity update collides on the local client. In all cases I'm uncertain how to handle the collision - aside from cheating, both states are "correct" but at different time periods. In the case of a remote entity it doesn't make sense to draw it walking through a wall, so I perform collision detection on the local client and cause it to "stop". Based on point #2 above, I might compute a "corrected vector" that continually tries to move the entity "through the wall" which will never succeed - the remote avatar is stuck there until the error gets too high and it "snaps" into position. How do games work around this?

    Say I have a simple mesh in Blender, with two keyframes, like so: Then, another animation for the same mesh, also with two keyframes: Theese animations worke fine in Blender and I can switch between them in the Dopesheet, where they are called "actions": The problem arises, when i try to export this to the Collada format, for use in my game engine. The only animation/action that seems to be carried over, is the one currently associated to the mesh. Is it possible to export multiple animations/actions for the same mesh, to the Collada format?

  • Hierarchy flattening of interfaces in WCF

    - by nmarun
    Alright, so say I have my service contract interface as below: 1: [ServiceContract] 2: public interface ILearnWcfService 3: { 4: [OperationContract(Name = "AddInt")] 5: int Add(int arg1, int arg2); 6: } Say I decided to add another interface with a similar add “feature”. 1: [ServiceContract] 2: public interface ILearnWcfServiceExtend : ILearnWcfService 3: { 4: [OperationContract(Name = "AddDouble")] 5: double Add(double arg1, double arg2); 6: } My class implementing the ILearnWcfServiceExtend ends up as: 1: public class LearnWcfService : ILearnWcfServiceExtend 2: { 3: public int Add(int arg1, int arg2) 4: { 5: return arg1 + arg2; 6: } 7:  8: public double Add(double arg1, double arg2) 9: { 10: return arg1 + arg2; 11: } 12: } Now when I consume this service and look at the proxy that gets generated, here’s what I see: 1: public interface ILearnWcfServiceExtend 2: { 3: [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/ILearnWcfService/AddInt", ReplyAction="http://tempuri.org/ILearnWcfService/AddIntResponse")] 4: int AddInt(int arg1, int arg2); 5: 6: [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/ILearnWcfServiceExtend/AddDouble", ReplyAction="http://tempuri.org/ILearnWcfServiceExtend/AddDoubleResponse")] 7: double AddDouble(double arg1, double arg2); 8: } Only the ILearnWcfServiceExtend gets ‘listed’ in the proxy class and not the (base interface) ILearnWcfService interface. But then to uniquely identify the operations that the service exposes, the Action and ReplyAction properties are set. So in the above example, the AddInt operation has the Action property set to ‘http://tempuri.org/ILearnWcfService/AddInt’ and the AddDouble operation has the Action property of ‘http://tempuri.org/ILearnWcfServiceExtend/AddDouble’. Similarly the ReplyAction properties are set corresponding to the namespace that they’re declared in. The ‘http://tempuri.org’ is chosen as the default namespace, since the Namespace property on the ServiceContract is not defined. The other thing is the service contract itself – the Add() method. You’ll see that in both interfaces, the method names are the same. As you might know, this is not allowed in WSDL-based environments, even though the arguments are of different types. This is allowed only if the Name attribute of the ServiceContract is set (as done above). This causes a change in the name of the service contract itself in the proxy class. See that their names are changed to AddInt / AddDouble respectively. Lesson learned: The interface hierarchy gets ‘flattened’ when the WCF service proxy class gets generated.

  • How to convince my boss that quality is a good thing to have in code?

    - by Kristof Claes
    My boss came to me today to ask me if we could implement a certain feature in 1.5 days. I had a look at it and told him that 2 to 3 days would be more realistic. He then asked me: "And what if we do it quick and dirty?" I asked him to explain what he meant with "quick and dirty". It turns out, he wants us to write code as quickly as humanly possible by (for example) copying bits and pieces from other projects, putting all code in the code-behind of the WebForms pages, stop caring about DRY and SOLID and assuming that the code and functionalities will never ever have to be modified or changed. What's even worse, he doesn't want us do it for just this one feature, but for all the code we write. We can make more profit when we do things quick and dirty. Clients don't want to pay for you taking into account that something might change in the future. The profits for us are in delivering code as quick as possible. As long as the application does what it needs to do, the quality of the code doesn't matter. They never see the code. I have tried to convince him that this is a bad way to think as the manager of a software company, but he just wouldn't listen to my arguments: Developer motivation: I explained that it is hard to keep developers motivated when they are constantly under pressure of unrealistic deadlines and budget to write sloppy code very quickly. Readability: When a project gets passed on to another developer, cleaner and better structured code will be easier to read and understand. Maintainability: It is easier, safer and less time consuming to adapt, extend or change well written code. Testability: It is usually easier to test and find bugs in clean code. My co-workers are as baffled as I am by my boss' standpoint, but we can't seem to get to him. He keeps on saying that by making things more quickly, we can sell more projects, ask a lower price for them while still making a bigger profit. And in the end these projects pay the developer's salaries. What more can I say to make him see he is wrong? I want to buy him copies of Peopleware and The Mythical Man-Month, but I have a feeling they won't change his mind either. A lot of you will probably say something like "Run! Get out of there now!" or "I'd quit!", but that's not really an option since .NET web development jobs are rather rare in the region where I live...

  • Canonicalization of single, small pages like reviews or product categories [SEO]

    - by Valorized
    In general I pretty much like the idea of canonicalization. And in most cases, Google explains possible procedures in a clear way. For example: If I have duplicates because of parameters (eg: &sort=desc) it's clear to use the canonical for the site, provided the within the head-tag. However I'm wondering how to handle "small - no to say thin content - sites". What's my definition of a small site? An Example: On one of my main sites, we use a directory based url-structure. Let's see: example.com/ (root) example.com/category-abc/ example.com/category-abc/produkt-xy/ Moreover we provide on page, that includes all products example.com/all-categories/ (lists all products the same way as in the categories) In case of reviews, we use a similar structure: example.com/reviews/product-xy/ shows all review for one certain product example.com/reviews/product-xy/abc-your-product-is-great/ shows one certain review example.com/reviews/ shows all reviews for all products (latest first) Let's make it even more complicated: On every product site, there are the latest 2 reviews at the end of the page. So you see, a lot of potential duplicates. Q1: Should I create canonicals for a: example.com/category-abc/ to example.com/all-categories/ b: example.com/reviews/product-xy/abc-your-product-is-great/ to example.com/reviews/product-xy/ or to example.com/review/ or none of them? Q2: Can I link the collection of categories (all-categories/) and collection of all reviews (reviews/ and reviews/product-xy/) to the single category respectively to the single review. Example: example.com/reviews/ includes - let's say - 100 reviews. Can I somehow use a markup that tells search engines: "Hey, wait, you are now looking at a collection of 100 reviews - do not index this collection, you should rather prefer indexing every single review as a single page!". In HTML it might be something like that (which - of course - does not work, it's only to show you what I mean): <div class="review" rel="canonical" href="http://example.com/reviews/product-xz/abc-your-product-is-great/">HERE GOES THE REVIEW</div> Reason: I don't think it is a great user experience if the user searches for "your product is great" and lands on example.com/reviews/ instead of example.com/reviews/product-xy/abc-your-product-is-great/. On the first site, he will have to search and might stop because of frustration. The second result, however, might lead to a conversion. The same applies for categories. If the user is searching for category-Z, he might land on the all-categories page and he has to scroll down to the (last) category, to find what he searched for (Z). So what's best practice? What should I do? Thank you for your help!

  • Can I stream Netflix to Ubuntu via a Mac?

    - by Chan-Ho Suh
    Right now I'm dual-booting Ubuntu and OS X. The only thing I use OS X for is watching the DRM-ed Netflix stream. I've looked into ways of watching Netflix on Ubuntu, but it seems the DRM basically makes that impossible (Moonlight project says unless Netflix drops the DRM their Silverlight replacement will not allow watching of Netflix). But then I realized, hey what if I stream Netflix to another computer running say, OS X, then somehow redirect it (using Unix magic) to my Ubuntu machine? Is this possible?

  • Justification for learning/implementing newer Microsoft technologies

    - by Darren
    I work at a large healthcare organization as a mid-level software developer. I have over 10 years experience in the IT industry using Microsoft technologies (ASP.NET & SQL Server). When I go to conferences, code camps, .net user group meetings, I hear of all kinds of new tools and technologies: MVC, LINQ, Entity Framework, WCF Web Services, etc. I guess you could say I'm in my comfort zone using the same old stuff from asp.net 2.0. I use typed datasets for my data access layer. I use web forms and feature rich server controls with master pages. I know how to use plain old SQL and create queries in my typed datasets to get at data my applications need. Throughout my career, I'm always sensitive to not become obsolete with my skill set. What I currently use works fine and my development time is fast. But I'm concerned that if I were to be laid off, I would be asked in interviews how many MVC apps I've written. Or how I am with LINQ or WCF web services. I know that it doesn't matter how many conferences, books, or videos I watch on some new technology...I have to implement/use it or it simply won't sink in. Also, managers who interview don't care how much someone reads up on something, only real use and experience with a technology. I have a new project to write. I've gone to my manager and have asked for additional time for the project for learning/implementing technology I may not be familiar with. Our organization encourages its employees to "learn and grow" and to continue are education. But I always get resistance when I ask for more time to ramp up on something new to implement. My manager is asking for concrete business reasons for implementing these new technologies. I don't have business reasons. My reasons are because I don't want to become obsolete. I could say it would make the project more maintainable in the future by other developers since at some point people could stop using these older technologies, but that' about all I can think of. Does Linq/Entity Framework/MCV apps perform better? So much so that the customers (users in departments I'm creating this app for) need? I doubt it. I'm interested in you guy's thoughts on this. Do many of you have similar plights with trying to use newer upcoming technologies? I doubt I'm on the bleeding edge of technology, either. Are there "business reasons" that you would bring to light for using these technologies? Thanks in advance! Sorry for the long wall of text.

  • Temporary Tables in Stored Procedures

    - by Paul White
    Ask anyone what the primary advantage of temporary tables over table variables is, and the chances are they will say that temporary tables support statistics and table variables do not. This is true, of course; even the indexes that enforce PRIMARY KEY and UNIQUE constraints on table variables do not have populated statistics associated with them, and it is not possible to manually create statistics or non-constraint indexes on table variables. Intuitively, then, any query that has alternative execution...(read more)

  • How to make a license apply to a whole library?

    - by Yannbane
    I'm creating a standard library for a programming language, and I'd like to license each and every single class or function in there under the MIT license, so they're completely FOSS. All of the files reside in a single directory. Would it be enough to put a LICENSE.txt file in the same directory, containing the MIT license? Do I need to say that the following license applies to all features of the library, or is the library itself considered to be a program?

  • Calling methods on Objects

    - by Mashael
    Let's say we have a class called 'Automobile' and we have an instance of that class called 'myCar'. I would like to ask why do we need to put the values that our methods return in a variable for the object? Why just don't we call the method? For example: Why should we write: string message = myCar.SpeedMessage(); Console.WriteLine(message); instead of: Console.WriteLine(myCar.SpeedMessage());
