• Should a web designer know server-side coding?

  - by Rasoul Zabihi

  We're implementing an CMS based on ASP.NET MVC. Now, any designer should be able to provide themes for this CMS. But to write a theme, they need to be able to modify the generated HTML, thus the concept of View. In other words, they should be capable to either modify current views, or create new views from scratch, to fit their requirements. However, now we're not sure that we're taking the right path. Should a web designer (HTML, CSS, JavaScript + Photoshop) really know about server-side platforms like Razor or PHP, or classic ASP, or anything else?

• Besides macros, are there any other metaprogramming techniques?

  - by mhr

  I'm making a programming language, and, having spent some time in Lisp/Scheme, I feel that my language should be malleable. Should I use macros, or is there something else I might/should use? Is malleable syntax even a good idea? Is it perhaps too powerful a concept? EDIT: In doing some research, I found fexprs. I don't really understand what these are. Help with that in an answer too please. EDIT2: Is it possible to have a language with macros/something-of-a-similar-nature without having s-expressions?

• New website, plans to go large. How do you protect yourself?

  - by John Redyns

  I'm planning to create a new site that (in hopes) will make it to a decent state of popularity and use. I have made sites before, but they weren't serious, with any intended purpose other than personal and friend use. I've never been able to find a solid post on good steps to protecting yourself, and your site/idea before you start. This site will always be free, and will not be bringing it any revenue by ads or whatnot, but I plan to in the future and would want to make I'm in the clear legally for one. Do you need to copyright anything? Or anything of the same concept as copyright? Do I make an LLC to operate it under? Apologies for this extremely poorly written question, basically I want to be both legal, and I want to make sure nobody can just rip my idea or name(s). (I'm sure this will be more concise as questions here are asked) Thanks

• Play 2 with Scala or Java?

  - by Mik378

  I want to develop a big personal project using Play 2 Framework. I am expert with Java language but it seems, with the few articles I read that Play 2 works perfectly and especially with Scala. I've never worked with Scala but I already learned concept as closures, functional programming etc... Learning it would be interesting. I am really motivated for but I wonder if there are some people who have started coding with Play2/Java and have changed for Play2/Scala that could explain their major concrete advantages.

• SSC Clinic: Can Implementing "Optimize for Ad Hoc Queries" Boost Performance for the SQLServerCentral.com and Simple-Talk.Com SQL Servers?

  With the introduction of the instance-level option “optimize for ad hoc workloads” in SQL Server 2008, DBAs have a tool to deal with a problem known as plan cache pollution, or plan cache bloat. It’s often caused when one-time use ad hoc queries are sent to SQL Server from Object-Relational Mapping (ORM) solutions, such as LINQ, NHibernate, or Entity Framework. The problem can prevent SQL Server from using its available memory optimally, potentially hurting performance.

  What Language is Unity written in? Also, where can i get its source code? I have an idea for a windowing enviroment or shell (dont know what to call it).

• I Don't Understand Anything About Randomly Generated Worlds [closed]

  - by Alex Larsen

  What tools do I need to make a Minecraft-like generated world? I heard about Perlin noise and Simplex, but I don't understand anything about them. So far all I found on the internet was a Simplex version for C#, and all it has is functions, and this is what I get: Console.WriteLine(Noise.Generate(SomeNumber, SomeNumber, SumNumber)); Outputs random floats. I'm really lost. I don't understand the whole random generated worlds concept. Can someone help me? And if I use the noise thing I don't understand how to use it.

• Are there any additional considerations to make when designing a site structure if you plan to use persistent connection technologies?

  - by Psytronic

  As the title states, I'm thinking of making a simple-card-game based website, using persistent connection technology (Something like signalR) for the actual game part of it. I've never planned a site to use this technology, and wondering for those who have, are there any additional things that need to be taken into consideration for the site structure? I'm planning on using the asp MVC framework for the whole thing, and starting off with some simple game (e.g. card based Rock/Paper/Scissors) for proof of concept (to see if I can get it working how I think it would in my head).

• Clarification on the Strategy Pattern

  - by Holly

  I've just been reading through some basic design patterns, Could someone tell me if the term "strategy pattern" only applies if your implementing a completely abstract interface? What about when your children (concretes?) inherit from a parent class (the strategy?) with some implemented methods and some virtual and/or abstract functions? Otherwise the rest of the implementation, the idea that you can switch between different children at run time, is identical. This is something i'm quite familiar with, i was wondering if you would still call it the Strategy Pattern or if that term only applies to using an interface. Apologies if this question is not appropriate! Or if this is just nitpicking :) I'm still learning and i'm not really sure if design patterns are quite heavily defined within the industry or just a concept to be implemented as you like.

• rotating menu with Actors in libgdx

  - by joecks

  I am intending to build a circular menu, with menu items equally distributed around the circle. When clicking on a menu item the circle should rotate so that the selected item is facing the top. I am using libgdx and I am not very familiar with the Actors concept, so I intuitivly tried to implement an Actor, who is drawing a texture and then transforming it by using Actions, with no success: class CircleActor extends Actor { @Override public void draw(SpriteBatch batch, float parentAlpha) { batch.draw(texture1, 100, 100); } @Override public Actor hit(float x, float y) { return this; } } and the rotate action: CircleActor circleActor = new CircleActor(); circleActor.action(Forever.$(RotateBy.$(0.1f, 0.1f))); // stage.addActor(); stage.addActor(circleActor); The texture is rectangular, but it doe not work. 1. What is wrong? 2. Is it a good approach to solve the task? Thanks!

• User Already Exists in the Current Database - SQL Server

  - by bullpit

  I was moving a lot of databases from one SQL Server to another, and my applications were giving me errors saying "Login failed for <user>". The user was already in the database with appropriate rights to allowed objects in the database. I tried mapping the user to the database and that's when I got this message: "User Already Exists in the Current Database"... I googled and found this very useful post about orphaned users when moving databases. These are the steps you should take to fix this issue: First, make sure that this is the problem. This will lists the orphaned users: EXEC sp_change_users_login 'Report' If you already have a login id and password for this user, fix it by doing: EXEC sp_change_users_login 'Auto_Fix', 'user' If you want to create a new login id and password for this user, fix it by doing: EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'

• Looking for games in environments similar to a pinball table

  - by chaosTechnician

  I'm on a team of students working on a third-person adventure game that takes place inside a pinball machine (like, small scale, on the surface, avoiding pinballs, etc). One of my responsibilities on the project is to find games that are similar to this concept in appearance and/or gameplay for reference. So, does anyone know of games (other than pinball) that takes place in a pinball-like environment? Or, adventure games that take place in small, cramped environments with multiple paths around the world? Or games in which the player is often bombarded with balls (or other similar unintelligent obstacles)? Or games that take place on a small scale?

• Which parallel pattern to use?

  - by Wim Van Houts

  I need to write a server application that fetches mails from different mail servers/mailboxes and then needs to process/analyze these mails. Traditionally, I would do this multi-threaded, launching a thread for fetching mails (or maybe one per mailbox) and then process the mails. We are moving more and more to servers where we have 8+ cores, so I would like to make use of these cores as much as possible (and not use 1 at 100% and leave the seven others untouched). So conceptually, as an example, it would be nice that I could write the application in such a way that two cores are "continuously" fetching emails and four cores are "continuously" processing/analyzing the emails (since processing and analyzing mails is more CPU intensive than fetching mails). This seems like a good concept, but after studying some parallel patterns, I'm not really sure how this is best implemented. None of the patterns really fit. I'm working in VS2012, native C++, but I guess from a design point of view this does not really matter and just some pointers on how to organize this would be great!

• career change : non-functional to test automation

  - by centennial

  I started my Career as core-Java developer 6 years ago and stayed as developer for 6-7 month and then moved to performance testing (actualy pushed into this for short term and later I started liking it). I have done all sort of non-functional testing like performance, load, stress, soak, compatibility, failover etc on many performance test tools accross many industries. I was doing contracting all these years which means I kept moving to new projects after every 3-6 months. Now personal situation has been changed, married man now so looking for something long term. Performance testing generally comes at the end of the development life cycle hence very short term contracts so I was wondering if I can move into functional/test automation side I can earn myself good length of contract. I had some exposure of QTP but I am sure to learn all other tools very quickly as I am quite good in programming and concept of testing. in short I want to move into functional test automation to get long term contract without leaving my love for programming . any thoughts please ?

  Ecopad : une tablette qui s'auto-recharge Avec la pression des doigts sur l'écran tactile Des designers coréens ont réalisé un nouveau concept de tablette doté d'une batterie auto-rechargeable baptisé EcoPad. Le système inventé par les designers Jun-se Kim, Yonggu Do et Eunha Seo et présente lors de compétition Fujitsu Design Award 2011, convertit l'énergie générée par la pression des doigts sur l'écran tactile pour la transformer en énergie électrique qui est ensuite utilisée par le dispositif. Selon une étude, les utilisateurs des terminaux tactiles pressent en moyenne 10 000 fois par jour l'écran de leur appareil. [IMG]http://rdonfack.developpez.com/images/ecopa...

  This article is cross-posted from my personal blog. In DotNetNuke version 5.3, we introduced the concept of a centralized Content store, together with the ability to apply Taxonomies (categories) to the content. We have extended this in DNN 5.4 by completing the MetaData API as well as adding Folksonomy (user tags). In this series of blogs I will explain how developers can take advantage of these new features in their own extensions. In the first blog in this series I covered the Taxonomy Manager...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
