  • How to really master ASP.NET MVC?

    - by user1620696
    Some years ago I've worked with web development just using PHP without focus on object orientation and so on. When I knew a little bit about it, and the benefits it brings, I've started moving to ASP.NET MVC. First, I've studied C# in the book Visual C# Step by Step. I've found it a good book for a beginner, and I could learn a lot of this new language with it. Now, when I've came to study ASP.NET MVC, I hadn't so much luck. I've studied on some books that explained MVC well and so on, but then started just saying: "do that, and now that, and then that", and I feel I couldn't really master ASP.NET MVC. I feel this, because when I was reading, I knew how to do the things the book taught, like implementing DI with Ninject and so on, but some time later, without looking at it for some time, I couldn't do it by myself. What I'm trying to say, is that usually I don't know where to start, how to do things in this framework and so on. How can I really master ASP.NET MVC? There is some book, some tutorial series, anything, that can really help with that? I'm pretty happy with the .NET framework, my problem isn't it, my only problem is working with the MVC framework, and applying the techniques from object orientation there. I don't know if this question is on-topic here, but I'm really just looking for some good references, to become better with this framework.

  • Office arangement - comfort vs. teamwork?

    - by finrod
    Our team works in an open-space office. Luckily the cubicles are quite big (L shaped tables for everyone!), there is quite a lot of space so we are not sandwiched. Without going into further detail, there are comfortable spots (window), normal spots and stupid spots (near the corridor). Until recently, the development team of twelve engineers was seated so that all types of spots were occupied and we were all close together. In the old arrangement, verbal communication was very easy - half of the team was withing talking distance. The other half was like ten steps away. Often times I could ask, discuss, solve problems without leaving the cube. Most of the communication is work related, no bullshit or mental masturbation that would unnecessarily distract others. Now we have moved to another part of the building and have larger space to occupy. At this point, everyone could pick their spot. Naturally all stupid spots are left empty (for the poor newcomers to occupy bwehaha). In the new arrangement, the development team is stretched across the floor and some of the key engineers are seated 'far' from each other - definitely not within talking distance. I have yet to experience how this works out but am getting concerned that team work and communication may have been traded for personal comfort. Finally the questions... What do you think is better office arrangement? Such that allows for free verbal communication but trading for some developer's comfort, or such that potentially hinders verbal communication but makes developer's more comfortable in their spot? Or maybe it does not matter at all and we will evolve to be efficient in any arrangement? What is your personal experience? Note - yes I read books and posts how workplace is important in our job. However in this case - we are all still in open space and the difference between the different spots are not really groundbreaking. So I'm thinking the little comfort that few developers gain is not worth the loss of easy communication.

  • How to analyze data

    - by Subhash Dike
    We are working on an application that allows user to search/read some content in a particular domain. We wanted to add some capability in the app which can suggest user some content based on the usage pattern (analyze data based on frequency and relevance). Currently every time user search or read something we do store that information in backend database. We would like to use this data to present some additional content to user. Could someone explain what kind of tools will be required for such a job and any example? And what this concept is called, data analysis? data mining? business intelligence? or something else? Update: Sorry for being too broad, here is an example SQL Database (Just to give an idea, actual db is little different with normalization and stuff) Table: UserArticles Fields: UserName | ArticleId | ArticleTitle | DateVisited | ArticleCategory Table: CategoryArticles Fields: Category | Article Title | Author etc. One Category may have one more articles. One user may have read the same article multiple times (in this case we place additional entry in the user article table. Task: Use the information availabel in UserArticle table and rank categories in order which would be presented to user automatically in other part of application. Factors to be considered are frequency and recency. This might be possible through simple queries or may require specialized tools. Either way, the task is what mention above. I am not too sure which route to take, hence the question. Thoughts??

  • How to write a blog for SEO purpose

    - by Mathieu Imbert
    I have a photo sharing website, which provides very little textual content. Users can add tags to photos and a description, but it creates a lot of duplicate content, because most of the descriptions will be 'wow', 'lol', ... I don't think I should rely on users to build my SEO. I think it would be a great idea to write a blog, and use it to describe the best photos, start contests, explain themes, in short: create original content that search engines will love. Our website's main URL is like www.domain.com, and our new blog is hosted on blog.domain.com. From a SEO perspective, is it a good idea to keep the blog separate from the main site? This has the advantage to leave the original site unchanged, but will it add any page rank to the www.domain.com? If the blog ranks well it will obviously pass some page rank to the original through links. What do you think is the best option from a SEO perspective? Include the blog in www.domain.com? Or leave it in blog.domain.com?

  • How do I give Ubuntu 10.10 more space (when installed inside Windows 7 (via wubi))?

    - by Pavitar
    I had installed Ubuntu inside Windows XP but then I formatted XP and installed Windows 7. EDIT1: I used Wubi for the same. I want to know which one of the two will solve my problem? creating a virtual disk or resizing root? Also is resizing root possible as the 4GB ext4 partition is already in a NTFS format Hard Drive partition. At the time of installation I had allocated only 4GB of space to Ubuntu. I want to increase that size as I keep getting a low disk space notification. I have surfed through a lot of similar questions but this is not a duplicate. Because I want to know a little about the file systems. In order to solve my problem,do I have to increase the size of root.disk? Or will it be solved by creating a virtual disk? Also I want to know the difference between creating a virtual disk and just increasing disk space of root.I'm new to Ubuntu so I don't know how the file systems function. EDIT2:I have created a virtual disk of 10gb ,but I'm still getting the same notification.Is there anyway to install all further applications on the virtual disk I created?

  • Best practices for App Idea ownership and shares

    - by JOG
    I am developing apps on my sparetime. I am the sole developer, and two non-programmer friends of mine provide vision, content, algorithms and ideas. We always agree happily on all the features, todos and prioritizations. But naturally, coding it is the biggest part. When selling, we agree on splitting profit equally, that is 33% each. But version 1.0 naturally does not sell much. And I go on to try to make the app more viral. This includes tons of stuff where the others are of little help. Examples: Adding support for sharing, facebook connect, gameifying, letting users add content, home page, support, maintenance, server services to make it easier for to update content. The list is long. Suddenly I will be doing 100% of a lot of work but only "own" a third of the income. My friends may either "fade out" of the project after 1.0, or they continue to contribute, but with less value and I would rather exchange them for more programmers or graphic designers. The effort they made to version 1.0 is worth a lot to the app and I realize I would have never done it without them. But I am doing all the work in the end. It is hard to negotiate about splitting 90, 5, 5 instead of 33% each, because the idea is still theirs. How to solve this? What are the best practices to regard the ownership of the app? What kind of agreements could I make that make it beneficial and motivational for me to continue developing the app?

    For next year's graduating class of computer science and engineering students, the world is their oyster. I believe that in today's day and age the opportunities for graduates are truly endless. Many students have a misconception that Oracle is mainly a Database Company. While we certainly are leaders in the database space, there is so much more that we do. If you look a little bit deeper you will find we have business groups within Oracle creating technical solutions across all areas of the business world. I think that the opportunities available at Oracle can be those 'life changing' roles that students are looking for where they will learn, develop, be challenged and still have the opportunity to be themselves. What other company provides as many choices for students as Oracle. The range of business and technical solutions we provide is enormous. At Oracle India we hire students across a range of different business groups. Below is a presentation showing you just some of the different business groups that hire graduates in Oracle India. The theme is 'choices' because we believe with the variety of work we do we provide the choice to allow you to be you. .prezi-player { width: 550px; } .prezi-player-links { text-align: center; } Oracle Campus Recruitment India: Choices on Prezi As you can see, here at Oracle you get the chance to allow 'You to be You'.

  • starting up with VPS or cloud hosting? [closed]

    - by FlyOn
    Possible Duplicate: How to find web hosting that meets my requirements? Summary: I want to start hosting my product. I'd like to register domains (at some point). I'm a linux beginner. Thinking about scalability and price, I'm thinking am I better off on a VPN to get started or would some form of cloud hosting be better (not being familiar with either). Full question: I'm creating a product where people can create their own 3D representations of whatever data / info they have, and (re)organise that data. The product is coming along beautifully on my local environment, but it's about time I start getting some form of hosting ready, and I could really use some advice where / how to get started: I'd like people to be able to move/register their own domains on my server. I could start without this just to demo the product, but it would be the very first on the todo list. I'd like to automatically copy some files / install databases etc for each domain. I probably want to see if I can let users manage their own subdomains at some points, but for now: I'd like start as simple as possible. I've always on a windows machine, so my linux experience is quite basic. I really don't mind getting into it, but I'm thinking it's better to get my product out first of all and see where to go from there. Although... I'd like things to be scalable. If I set up some reseller VPN now which only scales to 100 domains or so, which means I have to set up something else / move again when I pass that level, or which means that I'm in trouble if I suddenly get lots of new customers... hmm. Finally, I need to start cheap. I'm putting all I have into starting this company, and live on very little. So before I have any customers, 50 dollars a month is a fair bit and 100 dollars a month may be too much. If anyone has some tips to help get me started I'd be really grateful.

  • Need advice for approach for a web-based app that loads excel worksheet but exposes only the charts

    - by John
    I'm looking for suggestions on the Visual Studio approach to take for a web application that is in the conceptual stage. My environment has a lot of tools: Windows Server 2008 R2 Standard 64bit Visual Studio 2010 Professional Edition Sharepoint 2010 Server Enterprise Edition SQL Server 2008 R2 Office 2010 Professional I know I will need this app to retrieve data from a database (or a web service - not sure exactly at this point). The data needs to be placed in an Excel workbook dynamically. The app will need to have a nice user interface (standard web controls - perhaps with some Javascript effects). The Excel ribbon and worksheet grid will need to be hidden. Some web control(s) will cause the Excel chart(s) to be rendered. I am thinking this sounds like Visual Studio Tools for Office (VSTO) so as to leverage .Net and hide Excel. Can you offer suggestions regarding: One ASP.Net Web App Project One Class Library Project for Excel or perhaps which one of the several different Excel 2010 project types (addin, template, document) Would Excel Services for Sharepoint be useful (or required) ? I am feeling a little overwhelmed with so many choices at this early stage of conceptualizing the app. Can you suggest some ideas for this sort of thing? Also, I am a bit more experienced with C# but I've read VB.Net is better for work with the Excel object model. What are general advises with regard to tool choice and overall approach tradeoffs?

  • What Should I Do? [closed]

    - by Laxmidi
    What is a reasonable goal in terms of traffic for my Flex 3 site: www.brainpinata.com Since I began a couple of months ago, I've gotten roughly 5500 ad views and 280 ad clicks. And the ad revenue is a whopping $4.80. (I don't use Google Adsense). I advertise my site using Google Adwords to try to build traffic. My budget is $10/day. What should I do? a) Push the marketing. Add a blog. Try to get backlinks, contact blogs, start a Facebook page, tweet, etc. b) Google is only indexing the static content in the SWF. The questions/answers are pulled from a mySQL database. So, Google doesn't index 99% of the content. Should I re-do the site in HTML/Javascript and hard-code the questions for each puzzle? (This would be a challenge as I don't know javascript worth squat.) Or should I hard-code the questions in XML and put them in the Flex app? If I put the questions in an XML file it's roughly 500 KB. Other ideas? c) Should I switch ad networks? (I currently get about 100 visitors a day). My ad network pays so little that if I were to make even $500/month, I would need 550,000 ad views/month, which seems impossible. If I go ahead and switch ad networks, I need to find one that allows iFrames as I've got a Flex website. Which ad networks permit their ads to be shown in iFrames? d) Should I cut and run? I put a lot of work into this project and it would really stink to get nothing out of it. I'm looking for some good advice. Looking forward to your suggestions. Thank you. -Laxmidi

  • What kind of language will replace C++ as C++ replaced C ? [closed]

    - by jokoon
    I think I'm not totally wrong when thinking that C++0x (or C++1x) is still C++, just better, with functionnalities coming from boost. I can't stop thinking that computer sciences, even with all that has been made so far, have to evolve again. I don't really like D since it just try to be some sort of "what C++ should have been", and Go seems to be too sophisticated when I dig a little into it, especially after watching some presentation video like this one http://www.youtube.com/watch?v=rKnDgT73v8s The first thing that come into my mind is a new kind of syntax to directly handle specific datatypes and containers such as map, vectors, queues... What kind of things are researchers thinking about ? What are the real features that could make C++ better or a new C-like language could invent ? Does Go features such things ? Would there be a new kind of syntax that would "unbloat" C++ while keeping its advantages ? Could C++ have some of the interesting stuff of languages such as C# and ObjC ? EDIT: Please consider that I'm talking about a system language, not a VM/CLI/bytecode thing.

  • PowerShell a constant in a changing world

    - by Rob Addis
    I've been programming for about 20 years now some of my friends have been at it for over 30. I have read many, many manuals and yes it's not my favourite past time. So 10 years ago I made a promise to myself to try and only learn about products which have long life times. I immediately gave up programming GUIs and concentrated on back end development as I decided that these products (Oracle, MQ Series, SQL Server, BizTalk and later WCF, WF) have longer life times and smaller incremental changes than front end products.10 years ago I had no idea how good a decision that would turn out to be. There have been so many different Microsoft products for the front end in that time; multiple versions of Windows Forms, FrontPage, Html, Javascript, ASP.net, Silverlight, SharePoint, WPF and now hopefully a stayer Metro.I remember being at a Microsoft conference in 2006 when Martin Fowler told a crowd of developers (I'm paraphrasing) "If you don't like change then you're in the wrong business!". Well I've been in the business for 20 years and yes I'm a little resistant to change. I like my investment in reading manuals and getting certified to be time well spent!Over the last 2 years I have been writing A LOT of PowerShell script, I think there is a good chance this product will still be around and be used for new development in 10 years, learning it is a good investment.

  • Byte Size Tips: How to Show Google / Gmail Contacts in the OS X Contacts App

    - by The Geek
    The Contacts app on OS X isn’t very interesting, but if you can use it to display your Gmail contacts, it’ll get a little bit better. Luckily it’s pretty easy to add your Google / Gmail contacts, but you’ll have to click the mouse a few times and maybe poke at the old keyboard once or twice to type in your email address and password. It’s worth noting that if you set up Gmail in the Mail app you shouldn’t have to do this. Since we prefer Gmail in a browser, that’s why we’re writing this. Or just because we’re procrastinating the book editing that we’re supposed to be doing. Don’t judge. Start by opening the Preferences for the Contacts app by heading up to the Menu bar. Go to Accounts and then click the + sign to add a new one. Choose CardDAV for the account type, use your Gmail username and password, and put google.com as the server address. If you are using two-factor authentication, you’ll need to create a specific password for this account.

  • Sitecore Item Web API and Json.Net Test Drive (Part II –Strongly Typed)

    - by jonel
    In the earlier post I did related to this topic, I have talked about using Json.Net to consume the result of Sitecore Item Web API. In that post, I have used the keyword dynamic to express my intention of consuming the returned json of the API. In this article, I will create some useful classes to write our implementation of consuming the API using strongly-typed. We will start of with the Record class which will hold the top most elements the API will present us. Pretty straight forward class. It has 2 properties to hold the statuscode and the result elements. If you intend to use a different property name in your class from the json property, you can do so by passing a string literal of the json property name to the JsonProperty attribute and name your class property differently. If you look at the earlier post, you will notice that the API returns an array of items that contains all of the Sitecore content item or items and stores them under the result->items array element. To be able to map that array of items, we have to write a collection property and decorate that with the JsonProperty attribute. The JsonItem class is a simple class which will map to the corresponding item property contained in the array. If you notice, these properties are just the basic Sitecore fields. And here’s the main portion of this post that will binds them all together. And here’s the output of this code. In closing, the same result can be achieved using the dynamic keyword or defining classes to map the json propery returned by the Sitecore Item Web API. With a little bit more of coding, you can take advantage of power of strongly-typed solution. Have a good week ahead of you.

  • Implicit OAuth2 endpoint vs. cookies

    - by Jamie
    I currently have an app which basically runs two halves of an API - a restful API for the web app, and a synchronisation API for the native clients (all over SSL). The web app is completely javascript based and is quite similar to the native clients anyway - except it currently does not work offline. What I'm hoping to do is merge the fragmented APIs into a single restful API. The web app currently authenticates by issuing a cookie to the client whereas the native clients work using a custom HMAC access token implementation. Obviously a public/private key scenario for a javascript app is a little pointless. I think the best solution would be to create an OAuth2 endpoint on the API (like Instagram, for example http://instagram.com/developer/authentication/) which is used by both the native apps and the web app. My question is, in terms of security how does an implicit OAuth2 flow compare (storing the access token in local storage) to "secure" cookies? Presumably although SSL solves man in the middle attacks, the user could theoretically grab the access token from local storage and copy it to another machine?

  • How do I get others to see past my prior inexperience?

    - by Kevin
    My core question is how do I proceed from the following predicament. I will be honest with you, I wasted my College Experience. I slacked off and didn't take any of my comp sci classes that seriously, somehow i still got out with a 3.25 GPA. But truth be told I learned nothing. I befriended most of my professors who went pretty lenient on me in terms of grading. However, I basically came out of College knowing how to program a simple calculator in VB.Net. I was (to my great surprise) hired by a very large respected company in Denver as a Junior developer. Well the long and the short of it is that I knew so little about programming that I quickly became the office pariah and was almost fired due to my incompetence. It has been 8 months now and I feel I have learned some basic things and I am not as picked on as I used to be by the other developers. However, everyone hates me and the first few months have given the other developers a horrible perception of me. I am no longer afraid of code or learning, but I have put my self in the precarious position of being the scapegoat of our department. I hate going to work every day because no one there is my friend and pretty much everyone is hostile to me. What should I do? Any advice?

  • Adding 2D vector movement with rotation applied

    - by Michael Zehnich
    I am trying to apply a slight sine wave movement to objects that float around the screen to make them a little more interesting. I would like to apply this to the objects so that they oscillate from side to side, not front to back (so the oscillation does not affect their forward velocity). After reading various threads and tutorials, I have come to the conclusion that I need to create and add vectors, but I simply cannot come up with a solution that works. This is where I'm at right now, in the object's update method (updated based on comments): Vector2 oldPosition = new Vector2(spritePos.X, spritePos.Y); //note: newPosition is initially set in the constructor to spritePos.x/y Vector2 direction = newPosition - oldPosition; Vector2 perpendicular = new Vector2(direction.Y, -direction.X); perpendicular.Normalize(); sinePosAng += 0.1f; perpendicular.X += 2.5f * (float)Math.Sin(sinePosAng); spritePos.X += velocity * (float)Math.Cos(radians); spritePos.Y += velocity * (float)Math.Sin(radians); spritePos += perpendicular; newPosition = spritePos;

  • Is creating a separate pool for each individual image created from a png appropriate?

    - by Panzercrisis
    I'm still possibly a little green about object-pooling, and I want to make sure something like this is a sound design pattern before really embarking upon it. Take the following code (which uses the Starling framework in ActionScript 3): [Embed(source = "/../assets/images/game/misc/red_door.png")] private const RED_DOOR:Class; private const RED_DOOR_TEXTURE:Texture = Texture.fromBitmap(new RED_DOOR()); private const m_vRedDoorPool:Vector.<Image> = new Vector.<Image>(50, true); . . . public function produceRedDoor():Image { // get a Red Door image } public function retireRedDoor(pImage:Image):void { // retire a Red Door Image } Except that there are four colors: red, green, blue, and yellow. So now we have a separate pool for each color, a separate produce function for each color, and a separate retire function for each color. Additionally there are several items in the game that follow this 4-color pattern, so for each of them, we have four pools, four produce functions, and four retire functions. There are more colors involved in the images themselves than just their predominant one, so trying to throw all the doors, for instance, in a single pool, and then changing their color properties around isn't going to work. Also the nonexistence of the static keyword is due to its slowness in AS3. Is this the right way to do things?

  • Loose typing not applied to objects

    - by TecBrat
    I have very little experience working with classes and object. I work in a loosely typed language, PHP. I was working with a SimpleXML object and ran into a problem where I was trying to do math with an element of that object like $results->ProductDetail->{'Net'.$i}; If I echoed that value, I'd get 0.53 but when I tried to do math with it, it was converted to 0 Is there a reason that a loosely typed language would not recognize that as a float and handle it as such? Why would "echo" handle it as a string but the math fail to convert it? Example: $xml='<?xml version="1.0" encoding="UTF-8" ?>'; $xml.='<Test> <Item> <Price>0.53</Price> </Item> </Test>'; $result=simplexml_load_string($xml); var_dump($result->Item->Price); echo '<br>'; echo $result->Item->Price; echo '<br>'; echo 1+$result->Item->Price; echo '<br>'; echo 1+(float)$result->Item->Price; Output: object(SimpleXMLElement)#4 (1) { [0]=> string(4) "0.53" } 0.53 1 1.53

  • Lubuntu 12.04 on Acer laptop boots to blank blue screen

    - by WGCman
    My previous question on this was closed, but I am posting it again as the solution which my son eventually found may assist other users of the forum, or someone may be able to tweak the solution to improve the performance. Having installed Kubuntu 12.04.01 from a live USB onto my desktop, I wanted to do the same on my laptop, an Acer Aspire 1362 Laptop, which has 256MB RAM (actually 512 "on the box", but a good deal can be borrowed by the graphics!). I found Kubuntu wouldn't run on so little memory but downloaded: Lubuntu-12.04-alternate-i386.iso, which I understood was light enough to go. The laptop has one internal 40GB Toshiba hard drive divided into 3 partitions: C,19GB with Windows XP, Windows program files and some data, D, 19GB mostly data, and a small 2GB partition with some Acer software, which XP can't normally “see”. I transferred most of the contents of D to a memory stick, leaving 16GB free for Lubuntu. I did not want to dump XP yet, though it is painfully slow. I installed Lubuntu from then USB stick, accepting the default answers to most of the questions. The D: partition was further partitioned into a 500MB boot partition, 10GB for Linux, 2GB Swap and 6GB for data shareable between Linux and Windows. I had no error messages during installation, rebooted, was offered the choice of Ubuntu or XP, and selected the former. After a few minutes, I get a dark blue screen announcing Lubuntu with five dots underneath which lighten in turn. Eventually the lights stopped, and whatever I try the screen remains blank apart from “Lubuntu” I tried several solutions suggested on the forum for “identical” questions but without success.

  • Per-vertex animation with VBOs: Stream each frame or use index offset per frame?

    - by charstar
    Scenario Meshes are animated using either skeletons (skinned animation) or some form of morph targets (i.e. per-vertex key frames). However, in either case, the animations are known in full at load-time, that is, there is no physics, IK solving, or any other form of in-game pose solving. The number of character actions (animations) will be limited but rich (hand-animated). There may be multiple characters using a each mesh and its animations simultaneously in-game (they will be at different poses/keyframes at the same time). Assume color and texture coordinate buffers are static. Goal To leverage the richness of well vetted animation tools such as Blender to do the heavy lifting for a small but rich set of animations. I am aware of additive pose blending like that from Naughty Dog and similar techniques but I would prefer to expend a little RAM/VRAM to avoid implementing a thesis-ready pose solver. I would also like to avoid implementing a key-frame + interpolation curve solver (reinventing Blender vertex groups and IPOs). Current Considerations Much like a non-shader-powered pose solver, create a VBO for each character and copy vertex and normal data to each VBO on each frame (VBO in STREAMING). Create one VBO for each animation where each frame (interleaved vertex and normal data) is concatenated onto the VBO. Then each character simply has a buffer pointer offset based on its current animation frame (e.g. pointer offset = (numVertices+numNormals)*frameNumber). (VBO in STATIC) Known Trade-Offs In 1 above: Each VBO would be small but there would be many VBOs and therefore lots of buffer binding and vertex copying each frame. Both client and pipeline intensive. In 2 above: There would be few VBOs therefore insignificant buffer binding and no vertex data getting jammed down the pipe each frame, but each VBO would be quite large. Are there any pitfalls to number 2 (aside from finite memory)? Are there other methods that I am missing?

  • Happy Day! VS2010 SP1, Project Server Integration, Load Test Feature Pack

    - by Aaron Kowall
    Microsoft released a PILE of Visual Studio goodness today: Visual Studio 2010 SP1(Including TFS SP1) Finally done with remembering which GDR packs, KB Patches, etc need to be installed with a new VS/TFS 2010 deployment.  Just grab the SP1.  It’s available today for MSDN Subscribers and March 10th for public download. TFS-Project Server Integration Feature Pack MSDN Subscribers got another little treat today with the TFS-Project Server integration feature pack.  We can now get project rollups and portfolio level management with Project Server yet still have the tight developer interaction with TFS.  Finally we can make the PMO happy without duplicate entry or MS Project gymnastics. Visual Studio Load Test Feature Pack This is a new benefit for Visual Studio 2010 Ultimate subscribers.  Previously there was a limit to Ultimate Load Testing of 250 virtual users. If you needed more, you had to buy virtual user license packs.  No more.  Now your Visual Studio Ultimate license allows you to simulate as many virtual users as you need!!  This is HUGE in improving adoption of regular load testing for development projects. All the Details are available from Soma’s blog. Technorati Tags: VS2010,TFS,Load Test

  • Using prefix incremented loops in C#

    - by KChaloux
    Back when I started programming in college, a friend encouraged me to use the prefix incrementation operator ++i instead of the postfix i++, citing that there was a slight chance of better performance with no real chance of a downside. I realize this is true in C++, and it's become a general habit that I continue to do. I'm led to believe that it makes little to no difference when used in a loop in C#, regardless of data type. Apparently the ++ operator can't be overridden. Nevertheless, I like the appearance more, and don't see a direct downside to it. It did astonish a coworker just a moment ago though, he made the (fairly logical) assumption that my loop would terminate early as a result. He's a self-taught programmer, and apparently never came across the C++ convention. That made me question whether or not the equivalent behavior of pre- and post-fix increment and decrement operators in loops is well known enough. Is it acceptable for me to continue using ++i in looping constructs because of style preference, even though it has no real performance benefit? Or is it likely to cause confusion amongst other programmers? Note: This is assuming the ++i convention is used consistently throughout all code.

  • HTML5 media loading sometimes suspends or aborts: misconfigured Apache?

    - by Joan Botella
    Recently, some code that has been working fine for months started to run unexpectedly. That code is just a media files loading JavaScript function, that uses jQuery. It's pretty long, but in essence it is like this: var $audio=$('<audio>'); $audio.on('canplaythrough',function(e){ $audio[0].play(); }); $audio.attr('src','song.ogg'); Basically, the file only loads sometimes, and sometimes stops loading with a suspend or even an abort event. I have uploaded a little testing HTML to http://www.joanbotella.com/tests/loading , where you can see what's happening. You can download the test files from http://www.joanbotella.com/tests/loading/loadingTest.zip for local testing. I have just checked that opening the test index.html file directly into Firefox, and not through my localhost Apache server, makes the audio files perfectly playable. So, I assume, my hosting and I have the Apache server misconfigured for serving media files. My software versions are: Apache 2.2.22-1ubuntu1.7 , Mozilla Firefox 31.0 , Chromium 36.0.1985.125 and jQuery 1.11.0. Can you help me? Thanks in advance!

  • Ubuntu 12.04 Faster boot, Hibernate & other questions

    - by Samarth Shukla
    I've recently started exploring Ubuntu (my 1st distro). I fresh installed precise without a swap (4GB ram). The only issues are, slow boot (regardless of the swap) and instability after a few days of installation. The runtime performance is immaculate otherwise. Even though not needed, I still set swappiness = 10. I've tried the quiet splash profile to GRUB; already have preload installed. But it still is pretty slow. I am not too confident on recompiling the kernel yet. But you could please advice me on that too. I've also added the following to fstab: #Move /tmp to RAM: tmpfs /tmp tmpfs defaults,noexec,nosuid 0 0 (Also if you could please tell me the exact implication/scope of this tweak on physical ram & the swap.) But nothing has happened really. So what alternatives are there to make it boot faster? Also, right after fresh install, though no swap partition, the system still showed /dev/zram0 of arond 2GB which was never used (probably because of the above fstab edit). Finally, I experimented with Hibernate a little, but many claim that it doesn't work on 12.04. (Not to mention, I made a swap file of 4GB for it). What I did was: sudo gedit /var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla Then I added the following lines, saved the file, and closed the text editor: [Re-enable Hibernate] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes I also edited the upower policy for hibernate: gksudo gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy I added these lines: < allow_inactive >no< /allow_inactive > < allow_active >yes< /allow_active > But it did not work. So is there an alternate method perhaps that can make it work on 12.04?
