  • Game Review: Monument Valley

    Once again, it was a tweet that caught my attention... and the official description on the Play Store sounds good, too. "In Monument Valley you will manipulate impossible architecture and guide a silent princess through a stunningly beautiful world. Monument Valley is a surreal exploration through fantastical architecture and impossible geometry. Guide the silent princess Ida through mysterious monuments, uncovering hidden paths, unfolding optical illusions and outsmarting the enigmatic Crow People." So, let's check it out. What an interesting puzzle game Once again, I left some review on the Play Store: "Beautiful but short distraction Woohoo, what a great story behind the game. Using optical illusions and impossible geometries in this fantastic adventure of the silent princess just puts all the pieces perfectly together. Walking the amazing paths in the various levels and solving the riddles gives some decent hours of distraction but in the end you might have the urge to do more..." I can't remember exactly when and who tweeted about the game but honestly it caught my attention based on the simplicity of the design and the aspect that it seems to be an isometric design. The game relies heavily on optical illusions in order to guide to the silent princess Ida through her illusory adventure of impossible architecture and forgiveness. The game is set like a clockwork and you are turning, flipping and switching elements on the paths between the doors. Unfortunately, there aren't many levels and the game play lasted only some hours. Maybe there are more astonishing looking realms and interesting gimmicks in future versions. Play Store: Monument Valley Also, check out the latest game updates on the official web site of ustwo BTW, the game is also available on the Apple App Store and on Amazon Store for the Kindle Fire.

  • Using SQL tables for storing user created level stats. Is there a better way?

    - by Ivan
    I am developing a racing game in which players can create their own tracks and upload them to a server. Players will be able to compare their best track times to their friends and see world records. I was going to generate a table for each track submitted to store the best times of each player who plays the track. However, I can't predict how many will be uploaded and I imagine too many tables might cause problems, or is this a valid method? I considered saving each player's best times in a string in a single table field like so: level1:00.45;level2:00.43;level3:00.12 If I did this I wouldn't need a separate table for each level (each level could just have a row in a 'WorldRecords' table). However, this just causes another problem because the text would eventually reach the limit for varchar length. I also considered storing the times data in XML files. This would avoid database issues and server disk space can be increased if needed. But I imagine this would be very slow. To update one players best time on one level, I would have to check every node in the file to find their time record to update. Apologies for the wall of text. Any suggestions would be appreciated.

  • Hydraulics in game

    - by Mungoid
    I'm not completely sure if this would be better in the Physics site or not as this question is more about how hydraulics should work in game as opposed to how they really work (although that is taken into account) - So I apologize if this is in the wrong place. A project we are on, we have a machine with hydraulics that are powered (They don't just look like they move something, they are the only thing moving/turning/lifting something) - However, the hydraulic extends the same speed no matter what it is pushing. So, say there is a 10 ton object attached to one end of the hydraulic and the other end is attached to a plate on the ground. In real life it takes a few seconds to build up pressure depending on how heavy the object is, but in our project the hydraulics don't care about that. It will lift a 100 ton object the same speed as a 10 ton object. We have a way to fake the hydraulic pressurizing by reducing the 'drive amount' (how fast or slow the hydraulic extends) when we sense that it is touching the ground and that does a relatively decent job but we would like to be able to take other things into account like engine speed, ratios, loads, etc. but we aren't too sure what we need to think about. I'm kinda wondering if anyone here has any experience with this and could offer some suggestions on what to take into account?

  • Social Media APIs and Their C# Counterparts

    Whether it's talking about current events or sharing photos of a family vacation, the world is now addicted to social networks. Businesses recognize this, and these days every business wants social media addressed in their applications. Facebook, Twitter, and other sites provide powerful APIs you can use to harness the power of social networking in your own applications. However, most of these APIs tend to return data formatted in any number of syndication formats that can be quite painful to work with. Luckily, there are many free .NET based libraries that make interacting with these APIs a breeze. Over the next several weeks, I'll be posting some information and examples specific to some of these libraries. Here are a few of them now for your consumption... TweetSharp Twitter exposes its API in the form of three different APIs, two REST APIs and one Streaming API. These APIs can be queried by making HTTP GET/POST requests to a specific URL with some required parameters. Unfortunately, ...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.

  • Internet Explorer 9 is coming Monday to a web near you

    - by brian_ritchie
    Internet Explorer 9 is finally here...well almost.  Microsoft is releasing their new browser on March 14, 2011. IE9 has a number of improvements, including: Faster, Faster, Faster.  Did I mention it is faster?   With the new browsers coming out from Mozilla, Google, and Microsoft, there have been a flood of speed test coverage.  Chrome has long held the javascript speed crown.  But according to Steven J. Vaughan-Nichols over at ZDNET..."for the moment at least IE9 is actually the fastest browser I’ve tested to date."  He came to this revelation after figuring out that the 32-bit version of IE9 has the new Chakra JIT (the 64-bit version doesn't).  It also has a DirectX-based rendering engine so it can do cool tricks once reserved for desktop applications. Windows 7 Desktop Integration.  Read my post for more details.  Unfortantely, they didn't integrate my ideas...at least not yet :) Hot new UI.  Ok, they "borrowed" some ideas from Chrome...but that is the best form of flattery. Standards Compliance.  A real focus on HTML5 and CSS3.  Definite goodness for developers. So, go get yourself some IE9 on Monday and enjoy!

  • Work experience before masters

    - by RJadhav
    I dont know if its the right place to ask such questions: I have a bachelors degree from an Indian university. I want to persue masters in one of the universities in usa, my profile is good enough to get me admitted to the school that I want to get into. I also have an offer letter from one of the top software companies in India (Infosys). I dont know which path to take, I know a masters degree will be of great help in future both in terms of money and career but I do not know whether I want to do it at this moment. I have signed up for both edx and coursera for some of the courses and I really liked learning them online. I am not sure if taking these courses can be a substitute for a masters degree. Also how will i be able to differentiate myself in the real world if I do not have a masters degree, since there are many in india who dont have it. And is it advisable for me to take some work experience say 1-2 years and then apply for a masters degree. Although universities do not explicitly mention work experience as a criteria, will any kind of work experience help me in deciding whether i want to do masters? finally I want to know what are the cons of not doing a masters.

  • How to install .deb file from within preinst script

    - by Ashwin D
    I have my own application packaged using dpkg. The application depends on several deb files which I'm trying to install from within the preinst script of my application. The preinst script checks if a dependent deb file is installed, if not it goes to installt it using the dpkg -i command. This is repeated for all the dependent deb files needed by the main application. When I try to install the main application using dpkg -i, the commands returns failure when trying to execute the preinst script. Below is that error message. dpkg: error: dpkg status database is locked by another process I deleted /var/lib/dpkg/lock file and retried to install the application. But to no avail. If I run the preinst script separately like any other shell script, it runs without any issue. All the deb files will be installed properly. So, the issue is only when this preinst script is being run automatically by the dpkg -i command. I'm lost trying to determine the root cause. If anyone can shed some light on what the real issue might be, their help will be greatly appreciated. Thank you. Ashwin

  • Learning OO for a C Programmer

    - by Holysmoke
    I've been programming professionally in C, and only C, for around 10 years in a variety of roles. As would be normal to expect, I understand the idioms of the language fairly well and beyond that also some of the design nuances - which APIs to make public, who calls what, who does what, what is supposed to reentrant and so on. I grew up reading 'Writing Solid Code', it's early C edition, not the one based on C++. However, I've never ever programmed in an OO language. Now, I want to migrate to writing applications for iPhone (maybe android), so want to learn to use Objective-C and use it with a degree of competence fitting a professional programmer. How do I wrap my head around the OO stuff? What would be your smallest reading list suggestion to me. Is there a book that carries some sort of relatively real world example OO design Objective-C? Besides, the reading what source code would you recommend me to go through. How to learn OO paradigm using Objective-C?

  • Does your organization still use the term "screens" to describe a user interface?

    - by bit-twiddler
    I have been in the field long enough to remember when the term "screen" entered our lexicon. As difficult as it is to believe, the early systems on which I worked had no user interface (UI), that is, unless one counts a keypunch machine and job listings as a user interface. These systems ran as "card image" production jobs back in a day when being a computer operator required a reasonably deep understanding of how computers worked. Flashing forward to today: I cringe every time I hear a systems practitioner use the term "screen." The metaphor no longer fits the medium. The term somewhat fit back when the user dialog consumed 100% of available monitor real estate; however, the term lost its relevance the moment we moved to windowed environments. With the above said, does your organization still use the term "screens" to describe an application's UI? Has anyone successfully purged the term from an organization? For those who do not use the term to describe UI dialog elements, what term do you use in place of “screen.”

  • Data Center Modernization: Harness the power of Oracle Exalogic and Exadata with PeopleSoft

    - by Michelle Kimihira
    Author: Latha Krishnaswamy, Senior Manager, Exalogic Product Management   Allegis Group - a Hanover, MD-based global staffing company is the largest privately held staffing company in the United States with more than 10,000 internal employees and 90,000 contract employees. Allegis Group is a $6+ billion company, offering a full range of specialized staffing and recruiting solutions to clients in a wide range of industries.   The company processes about 133,000 paychecks per week, every week of the year. With 300 offices around the world and the hefty task of managing HR and payroll, the PeopleSoft system at Allegis  is a mission-critical application. The firm is in the midst of a data center modernization initiative. Part of that project meant moving the company's PeopleSoft applications (Financials and HR Modules as well as Custom Time & Expense module) to a converged infrastructure.     The company ran a proof of concept with four different converged architectures before deciding upon Exadata and Exalogic as the platform of choice.   Performance combined with High availability for running mission-critical payroll processes drove this decision.  During the testing on Exadata and Exalogic Allegis applied a particular (11-F) tax update in production environment. What job ran for roughly six hours completed in less than 1.5 hours. With additional tuning the second run of the Tax update 11-F reduced to 33 minutes - a 90% improvement!     Not only that, the move will help the company save money on middleware by consolidating use of Oracle licensing in a single platform.   Summary With a modern data center powered by Exalogic and Exadata to run mission-critical PeopleSoft HR and Financial Applications, Allegis is positioned to manage business growth and improve employee productivity. PeopleSoft applications run on engineered systems platform minimizing hardware and software integration risks.

  • Resolution changes when using switch

    - by Edward D
    So, the "real" resolution of my monitor is 1024x768. That's what I'd use on my docked Windows laptop, and what I'd use on my Xubuntu desktop connected directly. When I connect a switch, to switch between the two, however, the ubuntu machine's resolution changes. Everything's still proportional, and it still thinks it's doing 1024x768, but the icons and fonts appear larger. Not 800x600 larger, but still big. When I used Xubuntu Precise, I created an xorg.conf file to set a resolution of 1280x1024 which made it look the way it does without the switch ... as a workaround. When I upgraded to Trusty, I lost this. I tried to re-create it, but doesn't seem to load my file. Ideally, I'd like to correct the original problem, but I'd settle for being able to up the resolution. I searched for a while, and tried to do it, but I'm giving up ... please help me out.

  • How do I (quickly) let people know that software I am providing for free is not abandon-ware?

    - by blueberryfields
    As an independent, individual programmer: How do I let people very quickly know that I have not abandoned the software I've written and given away for free? That I am putting in the effort required to maintain and support my software to a professional level? When software written by one or two developers is available for free, or marked as open-source, usually the default assumption is that it's abandon-ware. This is usually a safe assumption - check out the answers to this question if you doubt it: Why do programmers write applications and then make them free?. There are lots of programmers who provide free and/or open-source tools which are not abandon-ware, though. If we're talking about large companies, ie Google, there's no real problem telling the difference between supported, live tools and software, and those which are abandoned or discontinued. A lively git repository isn't quick - users will have to be savvy enough to understand the repository and know where to look for it. Consistent marketing and community management take more time and effort than I can put in on my own. Also, if my software becomes popular/successful, I assume those will grow on their own, and be supported by power users in the community.

  • Collision and Graphics integration

    - by Shlomi Atia
    I'm a little confused about the integration between collision and graphics. They both need to share the same position in the world. The most obvious choice is the center of the entity, which is good for bounding volumes and fixed sized sprites. However, for characters with variable height size sprites like this: http://gamemedia.wcgame.ru/data/2011-07-17/game-sprite-sheet.jpg This is no longer good. The character won't align to the ground if I'll draw it from the center. I can just make the sprites the same height, but it will be a waste of memory (the largest sprite is 4 times larger then the smallest one). Even then, this is not an option at all with skeletal sprites like this one: http://user-generated-content.java-gaming.org/img-vault/212a171fc1ebb27ab77608fb9b2dd9bd9205361ce6300b21a7f8d06d025fbbd8.png It seems that the graphics need to be drawn from the ground for characters, but not for other images such as scenery and obstacles. The only solution I could think of was having another position called draw-position, which is the entity center for images, and is the the bottom of the collision volume for characters. Then when I draw relative to that position, it should work properly. I haven't found any references for something like that, so I'm kinda insecure about it. Does anyone knows of a better approach for this problem? Thanks

  • Configuring SQL Server Management Studio to use Windows Integrated Authentication &hellip; from non-

    - by Enrique Lima
    Did you know you can pass your Windows credentials to SQL Server even when working from a workstation that is not joined to a domain? Here is how … From Start, then click All Programs, find Microsoft SQL Server (version 2005 or 2008). Once there, do a right-click on SQL Server Management Studio, then click on Properties Now, follow below to modify the entry for Target: Now the real task (we will be using the runas command) … Modify the shortcut’s target as follows, and remember to replace <domain\user> with the values that correspond to your environment : x64 SQL Server 2008 C:\Windows\System32\runas.exe /user:<domain\user> /netonly "C:\Program Files (x86)\Microsoft SQL Server\100\Tools\binn\VSShell\Common7\IDE\Ssms.exe -nosplash" SQL Server 2005 C:\Windows\System32\runas.exe /user:<domain\user> /netonly "C:\Program Files (x86)\Microsoft SQL Server\90\Tools\binn\VSShell\Common7\IDE\SqlWb.exe -nosplash" x86 SQL Server 2008 C:\Windows\System32\runas.exe /user:<domain\user> /netonly "C:\Program Files\Microsoft SQL Server\100\Tools\binn\VSShell\Common7\IDE\Ssms.exe -nosplash" SQL Server 2005 C:\Windows\System32\runas.exe /user:<domain\user> /netonly "C:\Program Files\Microsoft SQL Server\90\Tools\binn\VSShell\Common7\IDE\SqlWb.exe -nosplash" Since we modified the shortcut, we will need to fix the icon for SSMS.  We will fix it by pressing the Change Icon… button and pointing to the original “icon” providers. It is the executables for SSMS that hold the icon information, so we need to point to … x64 SQL Server 2008 %ProgramFiles% (x86)\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Ssms.exe SQL Server 2005 C:\Program Files (x86)\Microsoft SQL Server\90\Tools\binn\VSShell\Common7\IDE\SqlWb.exe x86 SQL Server 2008 %ProgramFiles%\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Ssms.exe SQL Server 2005 C:\Program Files\Microsoft SQL Server\90\Tools\binn\VSShell\Common7\IDE\SqlWb.exe When you start SSMS from a modified shortcut, you’ll be prompted for your domain password: SSMS will show up stating a different account in the username box, but the parameters from the configuration you are doing above do work and will pass on correctly.

  • The Bing Sting - an alternative opinion

    - by Charles Young
    I know I'm a bit of an MS fanboy at times, but please, am I missing something here? Microsoft, with permission of users, exploits clickstream data gathered by observing user behaviour. One use for this data is to improve Bing queries. Google equips twenty of its engineers with laptops and installs the widgets required to provide Microsoft with clickstream data. It then gets their engineers to repeatedly (I assume) type in 'synthetic' queries which bring back 'doctored' hits. It asks its engineers to then click these results (think about this!). So, the behaviour of the engineers is observed and the resulting clickstream data goes off to Microsoft. It is processed and 'improves' Bing results accordingly.   What exactly did Microsoft do wrong here?   Google's so-called 'Bing sting' is clearly a very effective attack from a propaganda perspective, but is poor practice from a company that claims to do no evil. Generating and sending clickstream data deliberately so that you can then subsequently claim that your competitor 'copied' that data from you is neither fair nor reasonable, and suggests to me a degree of desperation in the face of real competition.   Monopolies are undesirable, whether they are Microsoft monopolies or Google monopolies.    Personally, I'm glad Microsoft has technology in place to observe user behaviour (with permission, of course) and improve their search results using such data. I can only assume Google doesn't implement similar capabilities. Sounds to me as if, at least in this respect, Microsoft may offer the better technology.

  • Do you keep your ideas secret? and why?

    - by MainMa
    I believe any programmer has several ideas that she/he considers as innovative or at least valuable. It may be an idea of a new product which will make this world better or a new development approach, etc. But a great idea must be implemented and promoted/advertised. This requires a lot of work (proofs of concept, prototypes, technology previews, etc.) and a lot of money (appropriate advertisement, marketing, etc.). So months later, the idea stays in our heads, but nothing else is done, because it's difficult, long and expensive, sometimes even impossible for a single developer. On the other hand, it would be painful to share our ideas, and see a medium-size company which has enough resources making something useful from it and having success and money. So what do you do with your ideas you can hardly implement or patent? Do you talk freely about them in discussion boards and with other developers? Do you keep them like a precious thing without never talking about them to anybody? If you keep your ideas, why are you doing so? Is it just because you hope that one day, you will be able to implement them and have a huge success, while you know very well by experience that it's an utopia?

  • When to use each user research method

    - by user12277104
    There are a lot of user research methods out there, but sometimes we get stuck in a rut, conducting all formative usability testing before coding, or running surveys to gather satisfaction data. I'll be the first to admit that it happens to me, but to get out of a rut, it just takes a minute to look at where I am in the design & development cycle, what kind(s) of data I need, and what methods are available to me. We need reminders, or refreshers, every once in a while. One tool I've found useful is a graphic organizer that I created many years ago. It's been through several revisions, as I've adapted it to the product cycles of the places I've worked, changed my mind about how to categorize it, and added methods that I've used or created over time. I shared a version of this table at the 2012 International UPA conference, and I was contacted by someone yesterday who wanted to use it in a university course on user-center design. I was flattered at the the thought, but embarrassed, because I was sure it needed updating -- that was a year ago, after all. But I opened it today, and really, there's not much I'd change -- sure, I could add some nuance regarding what types of formative testing, such as modality (remote, unmoderated remote, or in-person) or flavor of testing (RITE, RITE-Krug, comparative, performance), but I think it's pretty much ok as is. Click on the image below, to get the full-size PDF. And whether it's entirely "right" or "wrong" isn't the whole value of looking at these methods across the product lifecycle. The real value lies in the reminder that I have options. And what those options are change as the field changes, so while I don't expect this graphic to have an eternal shelf life, it's still ok a year after I last updated it. That said, if you find something missing or out of place, let me know :)

  • Essbase - FormatString

    - by THE
    A look at the documentation for "Typed Measures" shows:"Using format strings, you can format the values (cell contents) of Essbase database members in numeric type measures so that they appear, for query purposes, as text, dates, or other types of predefined values. The resultant display value is the cell’s formatted value (FORMATTED_VALUE property in MDX). The underlying real value is numeric, and this value is unaffected by the associated formatted value."To actually switch ON the use of typed measures in general, you need to navigate to the outline properties: open outline select properties change "Typed Measures enable" to TRUE (click to enlarge) As an example, I created two additional members in the ASOSamp outline. - A member "delta Price" in the Measures (Accounts) Dimension with the Formula: ([Original Price],[Curr_year])-([Original Price],[Prev_year])This is equivalent to the Variance Formula used in the "Years" Dimension. - A member "Var_Quickview" in the "Years" Dimension with the same formula as the "Variance" Member.This will be used to simply display a second cell with the same underlying value as Variance - but formatted using Format String hence enabling BOTH in the same report. (click to enlarge) In the outline you now select the member you want the Format String associated with and change the "associated Format String" in the Member Properties.As you can see in this example an IIF statement reading:MdxFormat(IIF(CellValue()< 0,"Negative","Positive" ) ) has been chosen for both new members.After applying the Format String changes and running a report via SmartView, the result is: (click to enlarge) reference: Essbase Database Admin Guide ,Chapter 12 "Working with Typed Measures "
