  • Choosing 3D modeling software Maya or 3D max?

    - by Kenneth J
    I've am a developer whose has spent most of my programming life developing web and business applications. I want to try my hand at something more challenging (but stay in the comfort of Visual Studio) ...perhaps XNA. Want 3D modeling software would be best for someone developing XNA? I have played with 3d MAX and Maya but never really did anything too involved. What are the pros and cons between them (in terms of game development)? Does one win out over the other for game development? Or is it pretty much just preference? I am new to game development and just trying to figure out the best tools to use before I really started. Any advice or other suggections would be greatly appreciated.

  • Switching from Visual Studio to Eclipse [closed]

    - by Jouke van der Maas
    I've been using Visual Studio for about 6 years now, which is enough time to know most useful keyboard shortcuts and little features. I recently had to switch to Eclipse and java for school, and now I'm constantly searching for the right keys to press. I have searched around for a definitve guide on this, but I couldn't find any. Here's what I want to know: For any feature in Visual Studio, what is the equivalent feature in Eclipse called and what is it's default keyboard shortcut? Are there any things that work very differently in Eclipse, that one might misunderstand or do wrong at first when switching? Are there features in Visual Studio that Eclipse does not have, and is there a workaround? I hope we can create a guide to make life easier for future developers that have to make this switch. You can answer any of the three questions above (no need to do all three), and multiple per answer if you want. I can't mark questions as community wiki anymore, but I do think that's appropriate here.

  • MS Grad Student Project

    - by Bernie Perez
    I'm a computer science grad student at UCLA specializing in security and/or mobile devices. I'm looking for ideas for my M.S. Project. Something with research and experimenting or testing. I have a few in mind, just wondering if the community has some good thoughts. I'm currently working on a project that deals with offload security related operations to a grid-powered/cloud server to improve battery life on phones or tablets, aka Security-Aware software on mobile devices. I might be able to expand on this for my project... but I'm open to any new types of ideas. I have another idea about secure communications with a peer-2-peer ad-hoc network, but its seems a little dull. Hope this questions is not off topic for this StackExchange. I look forward to hearing your thoughts and ideas.

  • Difference between $ and # in ADF/JSF/JSP

    - by pavan.pvj
    Found this one interesting. So, picked it from one of the books and posting here.JSP 2.1 and JSF 1.2 - both of them use a unified Expression language. One major and the most obvious difference is between $ and #. JSP 2.1 uses $ and JSF 1.2 uses # in an EL. $ - immediate evaluation# - deferred evaluation$ - $ syntax executes expressions eagerly/immediately, which means that the result is returned immediately when the page renders.# - # syntax defers the expression evaluation to a point defined by the implementing technology. In general, JSF uses deferred EL evaluation because of its multiple lifecycle phases in which events are handled. To ensure the model is prepared before the values are accessed by EL, it must defer EL evaluation until the appropriate point in the life cycle.Note: This is picked up from Oracle Fusion Developer Guide (ISBN: 9780071622547). There is also a very good article here:http://java.sun.com/products/jsp/reference/techart/unifiedEL.html

    - by Chris Hoffman
    Ubuntu is pretty snappy out-of-the-box, but there are some ways to take better advantage of your system’s memory and speed up the boot process. Some of these tips can really speed things up, especially on older hardware. In particular, selecting a lightweight desktop environment and lighter applications can give an older system a new lease on life. That old computer that struggles with Ubuntu’s Unity desktop can provide decent performance for years to come.

  • XML ou JSON? (pt-BR)

    - by srecosta
    Depende.Alguns de nós sentem a necessidade de escolher uma nova técnica / tecnologia em detrimento da que estava antes, como uma negação de identidade ou como se tudo que é novo viesse para substituir o que já existe. Chega a parecer, como foi dito num dos episódios de “This Developer’s Life”, que temos de esquecer algo para termos espaço para novos conteúdos. Que temos de abrir mão.Não é bem assim que as coisas funcionam. Eu vejo os colegas abraçando o ASP.NET MVC e condenando o ASP.NET WebForms como o anticristo. E tenho observado a mesma tendência com o uso do JSON para APIs ao invés de XML, como se o XML não servisse mais para nada. Já vi, inclusive, módulos sendo reescritos para trabalhar com JSON, só porque “JSON é melhor” ™.O post continua no meu blog: http://www.srecosta.com/2012/11/22/xml-ou-json/Grande abraço,Eduardo Costa

  • T-SQL Tuesday #005: On Technical Reporting

    - by Adam Machanic
    Reports. They're supposed to look nice. They're supposed to be a method by which people can get vital information into their heads. And that's obvious, right? So obvious that you're undoubtedly getting ready to close this tab and go find something better to do with your life. "Why is Adam wasting my time with this garbage?" Because apparently, it's not obvious. In the world of reporting we have a number of different types of reports: business reports, status reports, analytical reports, dashboards,...(read more)

  • Recap: Oracle Fusion Middleware Strategies Driving Business Innovation

    - by Harish Gaur
    Hasan Rizvi, Executive Vice President of Oracle Fusion Middleware & Java took the stage on Tuesday to discuss how Oracle Fusion Middleware helps enable business innovation. Through a series of product demos and customer showcases, Hassan demonstrated how Oracle Fusion Middleware is a complete platform to harness the latest technological innovations (cloud, mobile, social and Fast Data) throughout the application lifecycle. Fig 1: Oracle Fusion Middleware is the foundation of business innovation This Session included 4 demonstrations to illustrate these strategies: 1. Build and deploy native mobile applications using Oracle ADF Mobile 2. Empower business user to model processes, design user interface and have rich mobile experience for process interaction using Oracle BPM Suite PS6. 3. Create collaborative user experience and integrate social sign-on using Oracle WebCenter Portal, Oracle WebCenter Content, Oracle Social Network & Oracle Identity Management 11g R2 4. Deploy and manage business applications on Oracle Exalogic Nike, LA Department of Water & Power and Nintendo joined Hasan on stage to share how their organizations are leveraging Oracle Fusion Middleware to enable business innovation. Managing Performance in the Wrld of Social and Mobile How do you provide predictable scalability and performance for an application that monitors active lifestyle of 8 million users on a daily basis? Nike’s answer is Oracle Coherence, a component of Oracle Fusion Middleware and Oracle Exadata. Fig 2: Oracle Coherence enabled data grid improves performance of Nike+ Digital Sports Platform Nicole Otto, Sr. Director of Consumer Digital Technology discussed the vision of the Nike+ platform, a platform which represents a shift for NIKE from a  "product"  to  a "product +" experience.  There are currently nearly 8 million users in the Nike+ system who are using digitally-enabled Nike+ devices.  Once data from the Nike+ device is transmitted to Nike+ application, users access the Nike+ website or via the Nike mobile applicatoin, seeing metrics around their daily active lifestyle and even engage in socially compelling experiences to compare, compete or collaborate their data with their friends. Nike expects the number of users to grow significantly this year which will drive an explosion of data and potential new experiences. To deal with this challenge, Nike envisioned building a shared platform that would drive a consumer-centric model for the company. Nike built this new platform using Oracle Coherence and Oracle Exadata. Using Coherence, Nike built a data grid tier as a distributed cache, thereby provide low-latency access to most recent and relevant data to consumers. Nicole discussed how Nike+ Digital Sports Platform is unique in the way that it utilizes the Coherence Grid.  Nike takes advantage of Coherence as a traditional cache using both cache-aside and cache-through patterns.  This new tier has enabled Nike to create a horizontally scalable distributed event-driven processing architecture. Current data grid volume is approximately 150,000 request per minute with about 40 million objects at any given time on the grid. Improving Customer Experience Across Multiple Channels Customer experience is on top of every CIO's mind. Customer Experience needs to be consistent and secure across multiple devices consumers may use.  This is the challenge Matt Lampe, CIO of Los Angeles Department of Water & Power (LADWP) was faced with. Despite being the largest utilities company in the country, LADWP had been relying on a 38 year old customer information system for serving its customers. Their prior system  had been unable to keep up with growing customer demands. Last year, LADWP embarked on a journey to improve customer experience for 1.6million LA DWP customers using Oracle WebCenter platform. Figure 3: Multi channel & Multi lingual LADWP.com built using Oracle WebCenter & Oracle Identity Management platform Matt shed light on his efforts to drive customer self-service across 3 dimensions – new website, new IVR platform and new bill payment service. LADWP has built a new portal to increase customer self-service while reducing the transactions via IVR. LADWP's website is powered Oracle WebCenter Portal and is accessible by desktop and mobile devices. By leveraging Oracle WebCenter, LADWP eliminated the need to build, format, and maintain individual mobile applications or websites for different devices. Their entire content is managed using Oracle WebCenter Content and secured using Oracle Identity Management. This new portal automated their paper based processes to web based workflows for customers. This includes automation of Self Service implemented through My Account -  like Bill Pay, Payment History, Bill History and Usage Analysis. LADWP's solution went live in April 2012. Matt indicated that LADWP's Self-Service Portal has greatly improved customer satisfaction.  In a JD Power Associates website satisfaction survey, results indicate rankings have climbed by 25+ points, marking a remarkable increase in user experience. Bolstering Performance and Simplifying Manageability of Business Applications Ingvar Petursson, Senior Vice Preisdent of IT at Nintendo America joined Hasan on-stage to discuss their choice of Exalogic. Nintendo had significant new requirements coming their way for business systems, both internal and external, in the years to come, especially with new products like the WiiU on the horizon this holiday season. Nintendo needed a platform that could give them performance, availability and ease of management as they deploy business systems. Ingvar selected Engineered Systems for two reasons: 1. High performance  2. Ease of management Figure 4: Nintendo relies on Oracle Exalogic to run ATG eCommerce, Oracle e-Business Suite and several business applications Nintendo made a decision to run their business applications (ATG eCommerce, E-Business Suite) and several Fusion Middleware components on the Exalogic platform. What impressed Ingvar was the "stress” testing results during evaluation. Oracle Exalogic could handle their 3-year load estimates for many functions, which was better than Nintendo expected without any hardware expansion. Faster Processing of Big Data Middleware plays an increasingly important role in Big Data. Last year, we announced at OpenWorld the introduction of Oracle Data Integrator for Hadoop and Oracle Loader for Hadoop which helps in the ability to move, transform, load data to and from Big Data Appliance to Exadata.  This year, we’ve added new capabilities to find, filter, and focus data using Oracle Event Processing. This product can natively integrate with Big Data Appliance or runs standalone. Hasan briefly discussed how NTT Docomo, largest mobile operator in Japan, leverages Oracle Event Processing & Oracle Coherence to process mobile data (from 13 million smartphone users) at a speed of 700K events per second before feeding it Hadoop for distributed processing of big data. Figure 5: Mobile traffic data processing at NTT Docomo with Oracle Event Processing & Oracle Coherence

  • IIS 8 FTP

    - by The Official Microsoft IIS Site
    This post began its life as ‘What’s new in IIS 8 FTP’ but has since morphed into something quite different. As the ultimate goal is still to talk about what’s new with FTP for IIS 8, I have retained IIS, 8, and FTP in the title but nothing more. Many of us are cognizant of the history of the Internet but I will do a quick review to build the foundation of this post.

  • Image libraries sites to download pro images with no credits expiration policy

    - by Marco Demaio
    I found professional image libraries sites like http://www.istockphoto.com or http://www.dreamstime.com are quite useful to add some cool images to a website either when filling its contents or when designing its graphic layout. Unfortunately both of the site I listed above use credits plans that expires after 12 months: you buy credits (using real bucks) and then you can download images, but if you don't use all the credits within 1 year, thay suck them out from your virtual wallet (I think it's really unfair, but too bad for you, that's their policy). Do you know about other good image libraries sites (from your real life experience) that use credits to download images, but thay don't expire after 12 months? Obviously I won't ignore your suggestions about any other image libraries sites.

  • Differences between software testing processes and techniques?

    - by Aptos
    I get confused between these terms. For examples, should Unit testing be listed as a software testing process or technique? I think unit testing is a software testing technique. And how about Test driven development? Can you give me some examples for software testing processes and techniques? In my opinion, software testing process is a part of the software development life cycle. For example, if we use V-Model, the software testing process will be System test, Acceptance test, Integration Test... Thank you.

  • Massive Minecraft Creation Is a Functional Graphing Calculator

    - by Jason Fitzpatrick
    We’re no stranger to cool Minecraft creations, but this project takes Minecraft design to a whole new level. An industrious teen has built functional graphing calculator out of Minecraft blocks. It’s an absolutely enormous project that, if constructed in real life instead of in a virtual Minecraft space, would loom over a city. To fully appreciate how much ingenuity and effort went into the project, we’d suggest hitting up the comments over at Slashdot where commenters discuss the numerous obstacles and design tricks he would have needed to overcome and employ to pull the project off.

  • Just graduated from the finest graduates of the NeoSmart Technologies Institute of BCD Learning.

    - by Leonard Mwangi
    My laptop housing my life in entirety decided to go south this last weekend, cant blame it because I wanted it to do things that not even normal people :)  but it corrupted and could not get it going no matter what I tried. Imagining what I would loose (my POC's, Couple of VM's and lots and lots of documentation) pushed me to try anything short of reinstall. After toiling for about an hour looking for solution, I ended up at  http://neosmart.net/wiki/display/EBCD/Recovering+the+Vista+Bootloader+from+the+DVD where the last solution is the one that worked for me. I am glad to be functional again :) Thanks NeoSmart guys

  • C# XNA - Sky Sphere Question

    - by Wade
    I have been banging my head against the wall trying to get a sky sphere to work appropriately in XNA 4.0. I have the sphere loading correctly, and even textured, but i would like something a little more dynamic that can support a day/night cycle. My issue is that, while i know a good amount of C# and XNA, i know next to nothing about HLSL. (I could make an ambient light shader if my life depended on it...) I also have not been able to find a tutorial on how to build a sky sphere like this. Of course i don't expect to be able to make an amazing one right off the bat, i would like to start small, with a dynamic coloring sky i'll work out the clouds and sun later. My first question: Does anyone know of any good tutorial sites that could help me get a decent grasp around HLSL? Second: Does anyone have a good example of or know where to find one of a gradient sky using XNA and C#?

  • Dangerous programming

    - by benhowdle89
    Ok, i'm talking pure software/web, i'm not on about code to power Life Support machines or NASA rockets. In terms of software/web development what is the most dangerous single piece of code someone could put into a program (say if they had a grudge against a client/employee) In PHP, the first thing that comes to mind is some sort of file deletion: function EmptyDir($dir) { $handle=opendir($dir); while (($file = readdir($handle))!==false) { echo "$file <br>"; @unlink($dir.'/'.$file); } closedir($handle); } EmptyDir('images'); Or a PHP script that takes a user's sensitive input and posts it to Google sitemap or something? I hope this doesnt get closed off as subjective as there surely must be a ranking order of dangerous code. So i'm asking for the No.1 spot :) DISCLAIMER: I have no grudges against anyone, just curious for the answer!

  • Building a virtualized SPARC environment

    - by Owen Allen
    If you're interested in making effective use of virtualization tools like Oracle VM Server, there's a whitepaper on oracle.com that you should check out. The whitepaper starts with a few specific technologies and hardware: Oracle VM Server for SPARC, T4 Servers, Ops Center, Solaris 11, Sun Network 10GbE Switches, and Sun ZFS Storage Appliances. It then explains how to use them to plan and set up a virtualized environment, in which guests are grouped in Server Pools with high availability and are managed through Ops Center. It explains how Ops Center simplifies the management of logical domains by using custom plans to create new logical domains and managing their life cycle through its user interface. So, if you're interested in setting up a cloud and you want to avoid surprises along the way, have a look.

  • Computer-controlled Lights and Music Synced into Christmas Rock Spectacular

    - by Jason Fitzpatrick
    This spectacular computer controlled and synchronized lighting display combines thousands of feet of LED lighting, multiple controllers, and a rock medley to great effect. The above display started life as the personal Christmas light display of Sioux Falls, ND resident Joe Noe. When Noe moved, he donated his display to a local mall in order to preserve the tradition of people stopping by to see it and making donations to the Make-A-Wish foundation. The local mall, Western Mall, expanded the display and added in even more LEDs and controllers. The end result is an impressive display synced to a Christmas rock medley by UK musician Richard Campbell.

  • Are nvidia drivers necessary?

    - by Shubham Chaudhary
    The new Ubuntu 14.04 comes with nvidia driver options. My system(Dell XPS) uses nvidia-331. For starters it messed up my text font size. It is so freakishly small with nvidia drivers on. So my question is: Are these drivers really necessary? What performance gain do they provide? Will it help me save some battery life? Basically what are these drivers doing that I was missing before (with nouveau I guess)?

  • Web Developer interview questions

    - by Baba
    I read an article today that listed some basic questions about web development: Describe how POST data was submitted to a server by a browser. Explain a number of HTTP status codes (except maybe 404 and 500). Explain SOLID or name a design pattern. Explain ways to improve a page load speed or user experience. The author says "if you can’t answer the questions above there are a lot of people who wouldn’t think of you as a Senior Web Developer." My questions are: How relevant are these questions in respect to real life web programming and scalability? How true is that statement? In other words, do you consider this knowledge a requirement to be considered a Senior Web Developer? I was able to answer all the questions, too easily it seemed, so I'm wondering whether it is effective to use these or similar questions to screen developers rather than asking them to write sample code.

  • Where did ULSTraceLog go to in the SharePoint 2010 Logging Database?

    The Logging Database is one of the many new concepts that will make the life of many SharePoint administrators quite a bit more enjoyable. In SharePoint 2007 the Unified Logging System (ULS) logged all of its data to text files, typically found on your SharePoint server in 12\LOGS. We still have that in SharePoint 2010, but besides those text files, ULS can also write the data to a database! The advantages are obvious: easy to query, one central location for all servers in the farm, easy to build...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Setup site folders on Apache and PHP [closed]

    - by Cobus Kruger
    I'm trying to set up my first Apache server on my Windows PC at home and I have real trouble finding out which configuration settings go where. I downloaded and installed XAMPP which seemed to get everything nicely set up and can see a working website on http://localhost. So far so good. The point of this is to develop a website of course, and to make my life easier (irony?), I wanted to let the web site root point to my Eclipse project folder. So I opened httpd.conf, uncommented a VirtualHost block and changed its DocumentRoot to my local path. Now when I try to load http://localhost I get a 403 (Access denied) error. So where do I configure permissions for my folder? And is that all I need to let my site run from the folder specified or am I going to have to clear another hurdle?
