  • App Store: Profitability for Game Developers

    - by Bunkai.Satori
    Recent days, I've been spending significant time in discovering chances of profitability of AppStore for developers. I have found many articles. Some of them are highly optimistic, while other are extremely skeptical. This article is extremely skeptical. It even claims to have backed its conclusions by objective sales numbers. This is another pesimistic article saying that games developed by single individuals get 20 downloads a day. Can I kindly ask to clarify from business viewpoint whether average developers publishing games and software on AppStore can cover their living expenses, even, whether they can become profitable? Is it achievable to generate revenues of 50.000 USD yearly on AppStore for a single developer? I would like to stay as realistic as possible. Despite the question might look subjective, a good business man will be able to esitmate chances for profitability and prosperity within AppStore.

  • Clockwork: A 40,000 Piece K’Nex Ball Machine [Video]

    - by Jason Fitzpatrick
    You may have built a simple marble raceway out of construction toys like LEGO or K’Nex at some point in your life. No matter how grand a raceway it was, we can assure you it had nothing on this 40,000 piece room-sized monster. The creator, Austron, writes: This is Clockwork, my fifth major K’nex ball machine, and my largest and most complex K’nex structure to date. It took 8 months to build, has over 40,000 pieces, over 450 feet of track, 21 different paths, 8 motors, 5 lifts, and a one-of-a-kind computer-controlled crane, as well as two computer-controlled illuminated K’nex balls. For a more in-depth look at the construction we suggest checking out both his YouTube channel and his build blog.

  • Technical Computing Initiative, Jim Gray and a Virtual Framed Letter on my Wall

    Today Microsoft announced their Technical Computing Initiative, a program to help scientists and engineers take advantage of the latest breakthroughs in parallel computing, bandwidth increases, and technologies that will make doing scientific research akin to using spreadsheets (as opposed to writing really complex custom code).  This is actually the culmination of work that the late Jim Gray, formerly a technical fellow at Microsoft, was working on. I didn't really know Jim, and frankly only...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.

  • Correlating /var/log/* timestamps

    - by intuited
    /var/log/messages, /var/log/syslog, and some other log files use a timestamp which contains an absolute time, like Jan 13 14:13:10. /var/log/Xorg.0.log and /var/log/dmesg, as well as the output of $ dmesg, use a format that looks like [50595.991610] malkovich: malkovich malkovich malkovich malkovich I'm guessing/gathering that the numbers represent seconds and microseconds since startup. However, my attempt to correlate these two sets of timestamps (using the output from uptime) gave a discrepancy of about 5000 seconds. This is roughly the amount of time my computer was suspended for. Is there a convenient way to map the numeric timestamps used by dmesg and Xorg into absolute timestamps?

  • Advice on learning programming languages and math.

    - by Joris Ooms
    I feel like I'm getting stuck lately when it comes to learning about programming-related things; I thought I'd ask a question here and write it all down in the hope to get some pointers/advice from people. Perhaps writing it down helps me put things in perspective for myself aswell. I study Interactive Multimedia Design. This course is based on two things: graphic design on one hand, and web development on the other hand. I have quite a decent knowledge of web-related languages (the usual HTML/JS/PHP) and I'll be getting a course on ASP.NET next year. In my free time, I have learnt how to work with CodeIgniter, aswell as some diving into Ruby (and Rails) and basic iOS programming. In my first year of college I also did a class on Java (19/20 on the end result). This grade doesn't really mean anything though; I have the basics of OOP down but Java-wise, we learnt next to nothing. Considering the time I have been programming in, for example, PHP.. I can't say I'm bad at it. I'm definitely not good or great at it, but I'm decent. My teachers tell me I have the programming thing down. They just tell me I should keep on learning. So that's what I do, and I try to take in as much as possible; however, sometimes I'm unsure where to start and I have this tendency to always doubt myself. Now, for the 'question'. I want to get into iOS programming. I know iOS programming boils down to programming in Cocoa Touch and Objective-C. I also know Obj-C is a superset of C. I have done a class on C a couple of years ago, but I failed miserably. I got stuck at pointers and never really understood them.. Until like a month ago. I suddenly 'got' it. I have been working through a book on Objective-C for a week or so now, and I understand the basics (I'm at like.. chapter 6 or so). However, I keep running into similar problems as the ones I had when I did the C class: I suck at math. No, really. I come from a Latin-Modern Languages background in high school and I had nearly no math classes back then. I wanted to study Computer Science, but I failed there because of the miserable state of my mathematics knowledge. I can't explain why I'm suddenly talking about math here though, because it isn't directly related to programming.. yet it is. For example, the examples in the book I'm reading now are about programming a fraction-calculator. All good, I can do the programming when I get the formulas down.. but it takes me a full day or more to actually get to that point. I also find it hard to come up with ideas for myself. I made one small iOS app the other day and it's just a button / label kind of thing. When I press the button, it generates a random number. That's really all I could come up with. Can you 'learn' that? It probably comes down to creativity, but evidently, I'm not too great at being creative. Are there any sites or resources out there that provide something like a basic list of things you can program when you're just starting out? Maybe I'm focusing on too many things at once. I want to keep my HTML/CSS at a decent level, while learning PHP and CodeIgniter, while diving into Ruby on Rails and learning Objective-C and the iOS SDK at the same time. I just want to be good at something, I guess. The problem is that I can't seem to be happy with my PHP stuff. I want more, something 'harder'; that's why I decided to pick up the iOS thing. Like I said, I have the basics down of a lot of different languages. I can program something simple in Java, in C, in Objective-C as of this week.. but it ends there. Mostly because I can't come up with ideas for more complex applications, and also because I just doubt myself: 'Oh, that's too complex, I can never do that'. And then it ends there. To conclude my rant, let me basically rephrase my questions into a 'tl;dr' part. A. I want to get into iOS programming and I have basic knowledge of C/Objective-C. However, I struggle to come up with ideas of my own and implement them and I also suck at math which is something that isn't directly related to, yet often needed while programming. What can I do? B. I have an interest in a lot of different programming languages and I can't stop reading/learning. However, I don't feel like I'm good in anything. Should I perhaps focus on just one language for a year or longer, or keep taking it all in at the same time and hope I'll finally get them all down? C. Are there any resources out there that provide basic ideas of things I can program? I'm thinking about 'simple' command-line applications here to help me while studying C/Obj-C away from the whole iPhone SDK. Like I said, the examples in my book are mainly math-based (fraction calculator) and it's kinda hard. :( Thanks a lot for reading my post. I didn't plan it to be this long but oh well. Thanks in advance for any answers.

  • Oracle Desktop Virtualization Press Release

    - by [email protected]
    Even though Oracle has introduced new products (HW and SW) and pricing, and part numbers, modified licensing, and an EVP and an SVP have discussed openly where Oracle is going with Virtualization,  you may still have heard from "the other guys' that Oracle isn't going to be keeping the legacy Sun 'Desktop' portfolio.  I think that has soundly been addressed by the press release this morning.  Click here for the release.This is a great way to kick off Oracle's New (fiscal) Year.  As there are more announcements coming - I'll just say "Enjoy!, and "Stay Tuned".

  • How do one improve him/her problem-solving ability ?

    - by gcc
    How can one improve him/her problem-solving ability? Every one says same thing "a real programmer knows how to handle real problem", but they forget how they learn this ability, or where (I know in school, no one gives us any ability, of course in my opinion). If you have any idea except above ones, feel free when you give your advice solve more problems do more exercises, write code, search google then write more ... For me, my question is like "Use complex/known library instead of using your own." In other words,t I want your presonal experience, book recommendation, web page on problem solving. Moreover, look your problem-solving method and give us your personal ability as if it is an algorithm

  • OWB 11gR2: Migration and Upgrade Paths from Previous Versions

    - by antonio romero
    Over the next several months, we expect widespread adoption of OWB 11gR2, both for its new features and because it is the only release of Warehouse Builder certified for use with database 11gR2. Customers seeking to move existing environments to OWB 11gR2 should review the new whitepaper, OWB 11.2: Upgrade and Migration Paths. This whitepaper covers the following topics: The difference between upgrade and migration, and how to choose between them An outline of how to perform each process When and where intermediate upgrade steps are required Tips for upgrading an existing environment to 11gR2 without having to regenerate and redeploy code to your production environment. Moving up from 10gR2 and 11gR1 is generally straightforward. For customers still using OWB 9 or 10.1, it is generally possible to move an entire environment forward complete with design and runtime audit metadata, but the upgrade process can be complex and may require intermediate processing using OWB 10.2 or OWB 11.1. Moving a design by itself is much simpler, though it requires regeneration and redeployment. Relevant details are provided in the whitepaper, so if you are planning an upgrade at some point soon, definitely start there.

  • What is meant by "Repeat Business" ?

    - by vinoth
    Repeat Business obviously happens because the company has a great product or a great service. In the software industry, do companies make the code base complex enough so that the maintenance comes back to them? I have heard of cases where companies say "ya this code base has minor errors, let's ship them anyway, and let the customers come back for another change request on these". Then they would sometimes charge the customer for that. This question is specific to the software services industry. Do these things happen in the real world? I am trying to understand the business process.

  • How do I do TDD on embedded devices?

    - by Darth
    I'm not new to programming and I've even worked with some low level C and ASM on AVR, but I really can't get my head around a larger-scale embedded C project. Being degenerated by the Ruby's philosophy of TDD/BDD, I'm unable to understand how people write and test code like this. I'm not saying it's a bad code, I just don't understand how this can work. I wanted to get more into some low level programming, but I really have no idea how to approach this, since it looks like a completely different mindset that I'm used to. I don't have trouble understanding pointer arithmetics, or how allocating memory works, but when I see how complex C/C++ code looks compared to Ruby, it just seems impossibly hard. Since I already ordered myself an Arduino board, I'd love to get more into some low level C and really understand how to do things properly, but it seems like none of the rules of high level languages apply. Is it even possible to do TDD on embedded devices or when developing drivers or things like custom bootloader, etc.?

  • dual-boot (win-xp/ubu12.04) graphics card for ubu-desktop/win-xp-games

    - by iole1
    for work I need to get a a new and cheap graphics card for a dual boot machine: windows xp/ubuntu 12.04 LTS. The only requirements I have are: it should work 'flawlessly' in ubuntu (proprietary drivers are ok) it should handle Guild Wars 2 & League of Legends in windows xp (this is really the top priority as we need to be able to play at work :) - yes I have a cool job) I know nothing about graphics cards (and it seems to be a jungle out there). From other questions here and some webstigation I think I'd like to go for a Nvidia card, I've been trying to figure out what models fit the system req's but it seems they use different kind of model numbers so I don't get any wiser. tl;dr: will http://www.geforce.co.uk/hardware/desktop-gpus/geforce-gt-620-oem/specifications run Guild Wars 2 http://gamesystemrequirements.com/games.php?id=938 Or what is the worst card from nVidia that will run GW2 smoothly and work well in Ubuntu 12.04 Thanks!

  • Best in-memory cache of DB objects for Silverlight [closed]

    - by Jon
    Hi, I'd like to set up a cache of database objects (i.e. rows in a table) in memory in silverlight, which I'll do using WCF and linq-to-sql. Once I have the objects in memory, I'm planning on using MSMQ to receive new objects whenever they have been modified. It's a somewhat complex approach but the goal is to reduce trips to the database and allow instant data communication between Silverlight applications that are connected to the MSMQ. My Silverlight applications are meant to be long-running and the amount of data to be cached will not be large. I'm planning on saving the in-memory cache using local storage. Anyway, in order to process the updated objects that come in, I'd like to know if the user has changed the existing object. Could I use some event relating to data-binding to set a flag indicating that the object has changes? Maybe there's a better way to do the cache entirely? Thanks!

  • Demystified - BI in SharePoint 2010

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Frequently, my clients ask me if there is a good guide on deciphering the seemingly daunting choice of products from Microsoft when it comes to business intelligence offerings in a SharePoint 2010 world. These are all described in detail in my book, but here is a one (well maybe two) page executive overview. Microsoft Excel: Yes, Microsoft Excel! Your favorite and most commonly used in the world database. No it isn’t a database in technical pure definitions, but this is the most commonly used ‘database’ in the world. You will find many business users craft up very compelling excel sheets with tonnes of logic inside them. Good for: Quick Ad-Hoc reports. Excel 64 bit allows the possibility of very large datasheets (Also see 32 bit vs 64 bit Office, and PowerPivot Add-In below). Audience: End business user can build such solutions. Related technologies: PowerPivot, Excel Services Microsoft Excel with PowerPivot Add-In: The powerpivot add-in is an extension to Excel that adds support for large-scale data. Think of this as Excel with the ability to deal with very large amounts of data. It has an in-memory data store as an option for Analysis services. Good for: Ad-hoc reporting and logic with very large amounts of data. Audience: End business user can build such solutions. Related technologies: Excel, and Excel Services Excel Services: Excel Services is a Microsoft SharePoint Server 2010 shared service that brings the power of Excel to SharePoint Server by providing server-side calculation and browser-based rendering of Excel workbooks. Thus, excel sheets can be created by end users, and published to SharePoint server – which are then rendered right through the browser in read-only or parameterized-read-only modes. They can also be accessed by other software via SOAP or REST based APIs. Good for: Sharing excel sheets with a larger number of people, while maintaining control/version control etc. Sharing logic embedded in excel sheets with other software across the organization via REST/SOAP interfaces Audience: End business users can build such solutions once your tech staff has setup excel services on a SharePoint server instance. Programmers can write software consuming functionality/complex formulae contained in your sheets. Related technologies: PerformancePoint Services, Excel, and PowerPivot. Visio Services: Visio Services is a shared service on the Microsoft SharePoint Server 2010 platform that allows users to share and view Visio diagrams that may or may not have data connected to them. Connected data can update these diagrams allowing a visual/graphical view into the data. The diagrams are viewable through the browser. They are rendered in silverlight, but will automatically down-convert to .png formats. Good for: Showing data as diagrams, live updating. Comes with a developer story. Audience: End business users can build such solutions once your tech staff has setup visio services on a SharePoint server instance. Developers can enhance the visualizations Related Technologies: Visio Services can be used to render workflow visualizations in SP2010 Reporting Services: SQL Server reporting services can integrate with SharePoint, allowing you to store reports and data sources in SharePoint document libraries, and render these reports and associated functionality such as subscriptions through a SharePoint site. In SharePoint 2010, you can also write reports against SharePoint lists (access services uses this technique). Good for: Showing complex reports running in a industry standard data store, such as SQL server. Audience: This is definitely developer land. Don’t expect end users to craft up reports, unless a report model has previously been published. Related Technologies: PerformancePoint Services PerformancePoint Services: PerformancePoint Services in SharePoint 2010 is now fully integrated with SharePoint, and comes with features that can either be used in the BI center site definition, or on their own as activated features in existing site collections. PerformancePoint services allows you to build reports and dashboards that target a variety of back-end datasources including: SQL Server reporting services, SQL Server analysis services, SharePoint lists, excel services, simple tables, etc. Using these you have the ability to create dashboards, scorecards/kpis, and simple reports. You can also create reports targeting hierarchical multidimensional data sources. The visual decomposition tree is a new report type that lets you quickly breakdown multi-dimensional data. Good for: Mostly everything :), except your wallet – it’s not free! But this is the most comprehensive offering. If you have SharePoint server, forget everything and go with performance point. Audience: Developers need to setup the back-end sources, manageability story. DBAs need to setup datawarehouses with cubes. Moderately sophisticated business users, or developers can craft up reports using dashboard designer which is a click-once App that deploys with PerformancePoint Related Technologies: Excel services, reporting services, etc.   Other relevant technologies to know about: Business Connectivity Services: Allows for consumption of external data in SharePoint as columns or external lists. This can be paired with one or more of the above BI offerings allowing insight into such data. Access Services: Allows the representation/publishing of an access database as a SharePoint 2010 site, leveraging many SharePoint features. Reporting services is used by Access services. Secure Store Service: The SP2010 Secure store service is a replacement for the SP2007 single sign on feature. This acts as a credential policeman providing credentials to various applications running with SharePoint. BCS, PerformancePoint Services, Excel Services, and many other apps use the SSS (Secure Store Service) for credential control. Comment on the article ....

  • Gilda Garretón, a Java Developer and Parallelism Computing Researcher

    - by Yolande
    In a new interview titled “Gilda Garretón, a Java Developer and Parallelism Computing Research,” Garretón shares her first-hand experience developing with Java and Java 7 for very large-scale integration (VLSI) of computer-aided design (CAD). Garretón gives an insightful overview of how Java is contributing to the parallelism development and to the Electric VLSI Design Systems, an open source VLSI CAD application used as a research platform for new CAD algorithms as well as the research flow for hardware test chips.  Garretón considers that parallelism programming is hard and complex, yet important developments are taking place.  "With the addition of the concurrent package in Java SE 6 and the Fork/Join feature in Java SE 7, developers have a chance to rely more on existing frameworks and dedicate more time to the essence of their parallel algorithms."

  • What is a practical way to debug Rails?

    - by Joshua Fox
    I get the impression that in practice, debuggers are rarely used for Rails applications. (Likewise for other Ruby apps, as well as Python.) We can compare this to the usual practice for Java or VisualStudio programmers--they use an interactive debugger in a graphical IDE. How do people debug Rails applications in practice? I am aware of the variety of debuggers, so no need to mention those, but do serious Rails programmers work without them? If so, why do you choose to do it this way? It seems to me that console printing has its limits when debugging complex logic.

  • HTML Javascript Hidden Object or Photo Hunt Game

    - by PeteT
    Is anyone aware of any example photo hunt/hidden object games either in HTML and Javascript or flash if necessary? I am having trouble finding one, I may be using the wrong words to search. Photo hunt being like the wheres wally/waldo books where you look for wally in a complex image until you find him. So if it were played on screen you would press the location of wally and it would either be correct or wrong, possibly timed. I am hoping to find one where you can just load in your own photos and specify some co-ordinates that match where the hidden object is. A spot the difference example may be useful as a starting point but I haven't found an example of either that is web based yet.
