  • Webscale is all about sharding and its coming to SQL Azure

    - by simonsabin
    There are many that joke about developers always talking about webscale and needing to shard to be able to scale. In reality many systems, if not most, don’t need to be able to scale to numerous nodes because todays processing is so powerful. However in the cloud world where you don’t have 1 big box you have many little ones (instances) you need some way of sharding/federating/distributing data and load. I’ve mentioned before of a PDC presentation on whats coming in SQL Azure, well they’ve put some...(read more)

  • Software developer resume template/builder/etc

    - by codecraig
    As a software developer, I'm curious as to what tools, apps, templates, etc. other developers use for creating a resume. Such as LinkedIn, ceevee.com, github resume generator, etc. I use some of the things I've mentioned but I don't really like the out-dated style of resume created by ceevee.com, but I'm also not much of a designer. Anyone have any "nice" (as in design, ease of use) templates/apps/services you use?

  • Was I wrong about JavaScript?

    - by jboyer
    Yes, I was. Recently, I’ve taken a good hard look at JavaScript. I’ve used it before but mostly in the capacity of web design. Using JQuery to make your web page do cool stuff is different than really creating a JavaScript application using all of the language constructs. What I’m finding as I use it more is that I may have been wrong about my assumptions about it. Let me explain.   I enjoyed doing cool stuff with JQuery but the limited experience with JavaScript as a language coupled with the bad things that I heard about it led me to not have any real interest in it. However, JavaScript is ubiquitous on the web and if I want to do any web development, which I do, I need to learn it. So here I am, diving deep into the language with the help of the JavaScript Fundamentals training course at Pluralsight (great training for a low price) and the JavaScript: The Good Parts book by Douglas Crockford.   Now, there are certainly parts of JavaScript that are bad. I think these are well known by any developer that uses it. The parts that I feel are especially egregious are the following: The global object null vs. undefined truthy and falsy limited (nearly nonexistent) scoping ‘==’ and ‘===’ (I just don’t get the reason for coercion)   However, what I am finding hiding under the covers of the bad things is a good language. I am finding that I am legitimately enjoying JavaScript. This I was not expecting. I’m not going to go into a huge dissertation on what I like about it, but some things include: Object literal notation dynamic typing functional style (JavaScript: The Good Parts describes it as LISP in C clothing) JSON (better than XML) There are parts of JavaScript that seem strange to OOP developers like myself. However, just because it is different or seems strange does not mean it is bad. Some differences are quite interesting and useful.   I feel that it is important for developers to challenge their assumptions and also to be able to admit when they are wrong on a topic. Many different situations can arise that lead to this, such as choosing the wrong technology for a problem’s solution, misunderstanding the requirements, etc. I decided to challenge my assumptions about JavaScript instead of moving straight into CoffeeScript or Dart. After exploring it, I find that I am beginning to enjoy it the more I use it. As long as there are those like Crockford to help guide me in the right way to code in JavaScript, I can create elegant and efficient solutions to problems and add another ‘arrow’ to the ‘quiver’, so to speak. I do still intend to learn CoffeeScript to see what the hub-bub is about, but now I no longer have to be afraid of JavaScript as a legitimate programming language.   Has something similar ever happened to you? Tell me about it in the comments below.

  • How do you automate a SharePoint 2010 deployment?

    - by Enrique Lima
    In the last couple of months SharePoint traffic (consulting, training and speaking) has picked up.  And with that also the requests for deployments.  There are good, great, bad and really bad things around this. But that is for another topic.  However part of the good and great has been the fact of organizations wanting to do a proof of concept deployment (even when WSS or MOSS has been deployed). We can go through a session (Microsoft has the SDPS concept, SharePoint Deployment Planning Services) of discovering what the customer wants to achieve from their investment in the platform and then also proceed to model the solution that would fit their needs.  But it should not stop there.  The next step should be a POC (as many have requested) to test out. Now, on to the meat of this post.  How do I deploy?  While it is a good process to watch and see all of it take place, not many have the time to sit through that.  Even more so, when that has been part of the description of deploying the platform in the sessions mentioned above. I will, though, break it into a deployment for development purposes and a deployment of a farm. Two tools (or scripts) for those two different types of deployment. First, let me address the development environment.  Around the last week in October, Chris Johnson (SharePoint Product Team) announced a SharePoint Easy Setup for Developers.  The kit itself will assist you in installing SharePoint Server (in standalone mode), the tools that go around Visual Studio, Expression Studio and the Office 2010 tools. Here is the link to Chris’ post: http://blogs.msdn.com/b/cjohnson/archive/2010/10/28/announcing-sharepoint-easy-setup-for-developers.aspx The other scenario is the use of a script in assisting you through the deployment of a farm. Now, this is not to override planning.  It should highlight the need for planning even more.  How?  Having your service accounts planned, the structure of the sites and the scale of your deployment.  Enter AutoSPInstaller.  This is a CodePlex project, and the intent behind this is not only to automate the installation but to give some meaning and get some sense out of what goes on during a SharePoint deployment. How?  Take for example the creation of the databases, when we do the initial OOB deployment by using the wizard, more times than not, we leave the names as they are.  How is that a “bad thing”?  Let’s make it a better practice to rename those Databases, and have them take on a name that is not “GUID-ized”. Having a better naming convention will not hurt, on the other hand will allow for consistency. Here is the link to AutoSPInstaller’s site on CodePlex: http://autospinstaller.codeplex.com/

  • RegEx-Based Finding and Replacing of Text in SSMS

    So often, one sees developers doing repetitive coding in SQL Server Management Studio or Visual Studio that could be made much quicker and easier by using the Regular-Expression-based Find/Replace functionality. It is understandable, since the syntax is odd and some features are missing, but it is still worth knowing about.

  • How do you deal with design in Scrum?

    - by Seth
    How do you deal with design in Scrum? Do you still have well written design documents for each scrum iteration? Do you just do design notes featuring UML diagrams? Or do you just have well commented code? Each iteration may involve changing design so I just wanted to know how people capture this so new developers have an easy job of understanding the domain and getting on board as rapidly as possible.

  • On the art of self-promotion

    - by Tony Davis
    I attended Brent Ozar's Building the Fastest SQL Servers session at Tech Ed last week, and found myself engulfed in a 'perfect storm' of excellent technical and presentational skills coupled with an astute awareness of the value of promoting one's work. I spend a lot of time at such events talking to developers and DBAs about the value of blogging and writing articles, and my impression is that some could benefit from a touch less modesty and a little more self-promotion. I sense a reticence in many would-be writers. Is what I have to say important enough? Haven't far more qualified and established commentators, MVPs and so on, already said it? While it's a good idea to pick reasonably fresh and interesting topics, it's more important not to let such fears lead to writer's block. In the eyes of any future employer, your published writing is an extension of your resume. They will not care that a certain MVP knows how to solve problem x, but they will be very interested to see that you have tackled that same problem, and solved it in your own way, and described the process in your own voice. In your current job, your writing is one of the ways you can express to your peers, and to the organization as a whole, the value of what you contribute. Many Developers and DBAs seem to rely on the idea that their work will speak for itself, and that their skill shines out from it. Unfortunately, this isn't always true. Many Development DBAs, for example, will be painfully aware of the massive effort involved in tuning and adding resilience to rapidly developed applications. However, others in the organization who are unaware of what's involved in getting an application that is 'done' ready for production may dismiss such efforts as fussiness or conservatism. At the dark end of the development cycle, chickens come home to roost, but their droppings tend to land on those trying to clear up the mess. My advice is this: next time you fix a bug or improve the resilience or performance of a database or application, make sure that you use team meetings, informal discussions and so on to ensure that people understand what the problem was and what you had to do to fix it. Use your blog to describe, generally, the process you adopted, the resources you used and the insights that came from your work. Encourage your colleagues to do the same. By spreading the art of self-promotion to everyone involved in an IT project, we get a better idea of the extent of the work and the value of the contribution of all the team members. As always, we'd love to hear what you think. This very week, Simple-talk launches its new blogging platform. If any of this has moved you to 'throw your hat into the ring', drop us a mail at [email protected]. Cheers, Tony.

  • Microsoft and Application Architectures

    Microsoft has dealt with several kinds of application architectures to include but not limited to desktop applications, web applications, operating systems, relational database systems, windows services, and web services. Because of the size and market share of Microsoft, virtually every modern language works with or around a Microsoft product. Some of the languages include: Visual Basic, VB.Net, C#, C++, C, ASP.net, ASP, HTML, CSS, JavaScript, Java and XML. From my experience, Microsoft strives to maintain an n-tier application standard where an application is comprised of multiple layers that perform specific functions, for example: presentation layer, business layer, data access layer are three general layers that just about every formally structured application contains. The presentation layer contains anything to do with displaying information to the screen and how it appears on the screen. The business layer is the middle man between the presentation layer and data access layer and transforms data from the data access layer in to useable information to be stored later or sent to an output device through the presentation layer. The data access layer does as its name implies, it allows the business layer to access data from a data source like MS SQL Server, XML, or another data source. One of my favorite technologies that Microsoft has come out with recently is the .Net Framework. This framework allows developers to code an application in multiple languages and compiles them in to one intermediate language called the Common Language Runtime (CLR). This allows VB and C# developers to work seamlessly together as if they were working in the same project. The only real disadvantage to using the .Net Framework is that it only natively runs on Microsoft operating systems. However, Microsoft does control a majority of the operating systems currently installed on modern computers and servers, especially with personal home computers. Given that the Microsoft .Net Framework is so flexible it is an ideal for business to develop applications around it as long as they wanted to commit to using Microsoft technologies and operating systems in the future. I have been a professional developer for about 9+ years now and have seen the .net framework work flawlessly in just about every instance I have used it. In addition, I have used it to develop web applications, mobile phone applications, desktop applications, web service applications, and windows service applications to name a few.

  • What economic books would you suggest for learning about economic valuation of goods and simulations thereof?

    - by Rushyo
    I'm looking to create an economic model for a game based on goods created procedurally. Every natural resource and produced good would be procedurally generated, with certain goods being assigned certain uses. Fakesium might be used for the production of Weapon A and produced from Fakesium factories which use Dilithium and Widgets as reagents, where Widgets are also the product of Foo and Bar The problem is not creating the resources and their various production utlities - but getting the game's AI empires and merchants to (Addendum: somewhat) correctly value the goods according to their scarcity, utility and production costs. I need to create a simulation of goods which allows the various game factions to assign a common value denominator (credits) to each resource, depending on how much its worth to that empire. I see the simulation being something like: "I have a high requirement for Weapon A. Since I don't have much of Fakesium, which is needed for Weapon A - I must have a high demand for Fakesium. If I can acquire Fakesium, devalue it. If not, increase its value - and also increase demand for Dilithium and Widgets too." This is very naive - because it may be much much cheaper for the empire to simply purchase Dilithium and Widgets directly rather than purchasing Fakesium, for example. Another example is two resources might allow the creation of Weapon A (Fakesium and Lieron), so we'd need to consider that. I've been scratching my head over the problem and it keeps growing. By the time the player joins the world, I'd expect enough iterations of this process to have occurred that prices would have largely normalised - and would then only trigger rarely to compensate for major changes (eg. if the player blows up the world's only Foo mine!) Could anyone suggest resources (books, largely) which outline this style of modelling, preferably in the context of simulations? Since this problem would never occur outside fantasy worlds, I figured this is probably the most likely place to find people who have encountered similar problems and I'm sure there's people who know of good places for Games Developers to start looking at less specific economic theory too. Additionally, does anyone know of any developers with blogs whose games or research applications perform similar modelling? EDIT: I think I should underline that I'm not looking for optimal solutions. I'm looking to make the actors impulsive - making rudimentary decisions based on fuzzy inputs about what they care about or don't. I'm aiming to understand the problem area better not derive answers. All the textbooks I've found seem to be about real-world economics or how to solve complex theoretical problems, neither of which are terribly relevant to the actor's decision making.
