  • Best way to have common class shared by both C++ and Ruby?

    - by shuttle87
    I am currently working on a project where a team of us are designing a game, all of us are proficient in ruby and some (but not all) of us are proficient in c++. Initially we made the backend in ruby but we ported it to c++ for more speed. The c++ port of the backend has exactly the same features and algorithms as the original ruby code. However we still have a bunch of code in ruby that does useful things but we want it to now get the data from the c++ classes. Our first thought was that we could save some of the data structures in something like XML or redis and call that, but some of the developers don't like that idea. We don't need anything particularly complex data structures to be passed between the different parts of the code, just tuples, strings and ints. Is there any way of integrating the ruby code so that it can call the c++ stuff natively? Will we need to embed code? Will we have to make a ruby extension? If so are there any good resources/tutorials you could suggest? For example say we have this code in the c++ backend: class The_game{ private: bool printinfo; //print the player diagnostic info at the beginning if true int numplayers; std::vector<Player*> players; string current_action; int action_is_on; // the index of the player in the players array that the action is now on //more code here public: Table(std::vector<Player *> in_players, std::vector<Statistics *> player_stats ,const int in_numplayers); ~Table(); void play_game(); History actions_history; }; class History{ private: int action_sequence_number; std::vector<Action*> hand_actions; public: void print_history(); void add_action(Action* the_action_to_be_added); int get_action_sequence_number(){ return action_sequence_number;} bool history_actions_are_equal(); int last_action_size(int street,int number_of_actions_ago); History(); ~History(); }; Is there any way to natively call something in the actions_history via The_game object in ruby? (The objects in the original ruby code all had the same names and functionality) By this I mean: class MyRubyClass def method1(arg1) puts arg1 self.f() # ... but still available puts cpp_method.the_current_game.actions_history.get_action_sequence_number() end # Constructor: def initialize(arg) puts "In constructor with arg #{arg}" #get the c++ object here and call it cpp_method end end Is this possible? Any advice or suggestions are appreciated.

  • Copying subversion commit messages

    - by Falcor
    I know this isn't the BEST practice, but every once in a while when I'm merging up a huge batch up changes with the trunk (and I know my branch is current), I will simply delete the contents of the trunk and then copy the contents of my branch up, so that I don't have to deal with resolving conflicts for an hour. The problem is that I seem to lose the entire history of commit messages for each file. My branch still has the correct history of commit messages... how can I merge them up?

    I need create a programatic equivalent using delphi language... or could someone post a link on how to do grammars in peech recogniton using the delphi. sorry for my english... **Programmatic Equivalent C#:** Ref: http://msdn.microsoft.com/en-us/library/ms723634(v=VS.85).aspx To add a phrase to a rule, SAPI provides an API called ISpGrammarBuilder::AddWordTransition. The application developer can add the sentences as follows: SPSTATEHANDLE hsHelloWorld; // Create new top-level rule called "HelloWorld" hr = cpRecoGrammar->GetRule(L"HelloWorld", NULL, SPRAF_TopLevel | SPRAF_Active, TRUE, &hsHelloWorld); // Check hr // Add the command words "hello world" // Note that the lexical delimiter is " ", a space character. // By using a space delimiter, the entire phrase can be added // in one method call hr = cpRecoGrammar->AddWordTransition(hsHelloWorld, NULL, L"hello world", L" ", SPWT_LEXICAL, NULL, NULL); // Check hr // Add the command words "hiya there" // Note that the lexical delimiter is "|", a pipe character. // By using a pipe delimiter, the entire phrase can be added // in one method call hr = cpRecoGrammar->AddWordTransition(hsHelloWorld, NULL, L"hiya|there", L"|", SPWT_LEXICAL, NULL, NULL); // Check hr // save/commit changes hr = cpRecoGrammar->Commit(NULL); // Check hr XML Grammar Sample(s): <GRAMMAR> <!-- Create a simple "hello world" rule --> <RULE NAME="HelloWorld" TOPLEVEL="ACTIVE"> <P>hello world</P> </RULE> <!-- Create a more advanced "hello world" rule that changes the display form.

  • scalability: when to use CDN?

    - by ajsie
    i've read about CDN but dont know exactly what it is for. lets say i've got an international social network (text and image content), and it's growing in traffic from different countries, do i have use of CDN? the picture i got from the sources i've read is that it copy your content and put it in many servers spread out over the world so that users will fetch it from the nearest point. does this mean that every server has a copy of my mysql database and the image files? is this the proper way to make your web service available for the world? cause how else could you set up a servers through out the world, contacting hosting companies for each country?

  • DSL connection dropping when starting game

    - by bootoo
    New connection set up last week - have called tech support, signal fine, sending out tech guy tomorrow - however i cant make sense of this using Vista, 2wire connection 6mb ATT conn, wireless, i can browse website, stream video from my PC wirelessly to my xbox, watch Hulu in high res, connection seems fine I load up World of Warcraft, i select Enter World and without fail my 2wire modem 'DSL' light goes red, my internet light goes out, im no longer connected, then after 10 or 15 seconds it works again, but game has kicked me Noticed the same thing on opening or closing Utorrent as well No other phones/devices plugged into the phone jacks in the apartment - why would joining a game cause my DSL to drop? i can only guess it throws a bunch of information to the server when i hit 'enter world' and that causes an issue that shuts my connection down or my router hates me - all help appreciated

  • xargs -I replace-str option difference

    - by foresightyj
    From my understanding, the following should mean exactly the same: ls -1 | xargs file {} ls -1 | xargs -I{} file {} if -I option is not specified, it is default to -I{}. I want to list all files in the current directory and run file command on each of them. Some have spaces in their names. However, I noticed the difference. See below: $ ls -1 Hello World $ ls -1 | xargs file {} {}: ERROR: cannot open `{}' (No such file or directory) Hello: ERROR: cannot open `Hello' (No such file or directory) World: ERROR: cannot open `World' (No such file or directory) $ ls -1 | xargs -I{} file {} Hello World: directory With -I{} explicitly specified, blanks in file names are treated as expected.

  • Isn't NAT a MUST when a LAN uses rfc 1918 private IPs?

    - by aks
    Isn't NAT a MUST when a LAN uses rfc 1918 private IPs? Can an organization assign its hosts with private IPs and still communicate with the external world without NAT? how can an internal host with a private IP (say 10.1.1.1) communicate with external world without NAT? I mean, how can the reply/response packet from the external world reach the original source as the packet with Dest IP = 10.1.1.1 will get lost as it can not be routed as many organizations can use the same IP. Why doesn't rfc 1918 (Address Allocation for Private Internets) make any mention of NAT?

  • View Script Over SSH?

    - by user74781
    A friend, using a remote machine, ran a script that SSHed to my machine, and ran the following python script that resides on my machine: while (1): ....print "hello world" (this script simply prints 'hello world' continuously). I am now logged in to my machine. How can I see the output of the script my friend was running? if it helps, I can 'spot' the script my friend is using: me@home:~$ ps aux | grep justprint.py **friend 7494 12.8 0.3 7260 3300 ?

  • XNA: Camera's Rotation and Translation matrices seem to interfere with each other

    - by Danjen
    I've been following the guide here for how to create a custom 2D camera in XNA. It works great, I've implemented it before, but for some reason, the matrix math is throwing me off. public sealed class Camera2D { public Vector2 Origin { get; set; } public Vector2 Position { get; set; } public float Scale { get; set; } public float Rotation { get; set; } } It might be easier to just show you a picture of my problem: http://i.imgur.com/H1l6LEx.png What I want to do is allow the camera to pivot around any given point. Right now, I have the rotations mapped to my shoulder buttons on a gamepad, and if I press them, it should rotate around the point the camera is currently looking at. Then, I use the left stick to move the camera around. The problem is that after it's been rotated, pressing "up" results in it being used relative to the rotation, creating the image above. I understand that matrices have to be applied in a certain order, and that I have to offset the thing to be rotated around the world origin and move it back, but it just won't work! public Matrix GetTransformationMatrix() { Matrix mRotate = Matrix.Identity * Matrix.CreateTranslation(-Origin.X, -Origin.Y, 0.00f) * // Move origin to world center Matrix.CreateRotationZ(MathHelper.ToRadians(Rotation)) * // Apply rotation Matrix.CreateTranslation(+Origin.X, +Origin.Y, 0.00f); // Undo the move operation Matrix mTranslate = Matrix.Identity * Matrix.CreateTranslation(-Position.X, Position.Y, 0.00f); // Apply the actual translation return mRotate * mTranslate; } So to recap, it seems I can have it rotate around an arbitrary point and lose the ability to have "up" move the camera straight up, or I can rotate it around the world origin and have the camera move properly, but not both.

  • Need help transforming DirectX 9 skybox hlsl shader to DirectX 11

    - by J2V
    I am in the middle of implementing a skybox to my game. I have been following this tutorial http://rbwhitaker.wikidot.com/skyboxes-2. I am using MonoGame as a framework and in order to support both Windows and Windows 8 metro I need to compile the shader with pixel and vertex shader 4. compile vs_4_0_level_9_1 compile ps_4_0_level_9_1 However some of the hlsl syntax has been updated with DX10 and DX11. I need to update this hlsl code: float4x4 World; float4x4 View; float4x4 Projection; float3 CameraPosition; Texture SkyBoxTexture; samplerCUBE SkyBoxSampler = sampler_state { texture = <SkyBoxTexture>; magfilter = LINEAR; minfilter = LINEAR; mipfilter = LINEAR; AddressU = Mirror; AddressV = Mirror; }; struct VertexShaderInput { float4 Position : POSITION0; }; struct VertexShaderOutput { float4 Position : POSITION0; float3 TextureCoordinate : TEXCOORD0; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; float4 worldPosition = mul(input.Position, World); float4 viewPosition = mul(worldPosition, View); output.Position = mul(viewPosition, Projection); float4 VertexPosition = mul(input.Position, World); output.TextureCoordinate = VertexPosition - CameraPosition; return output; } float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { return texCUBE(SkyBoxSampler, normalize(input.TextureCoordinate)); } technique Skybox { pass Pass1 { VertexShader = compile vs_2_0 VertexShaderFunction(); PixelShader = compile ps_2_0 PixelShaderFunction(); } } I quess I need to change Texture into TextureCube, change sampler, swap texCUBE() with TextureCube.Sample() and change PixelShader return semantic to SV_Target0. I'm very new in shader languages and any help is appreciated!

  • IASA Sessions on Social Networking Note Influence of Millennial Generation on Insurance Technology

    - by [email protected]
    Helen Pitts, senior product marketing manager for Oracle Insurance is blogging from the 2010 IASA Annual Conference and Business Show this week. Social networking continues to be a buzzword for many in the industry. Erin Esurance, the Geico Gecko and even Nationwide's "The World's Greatest Spokesperson in the World" all have a prominent presence in the social media world. Sessions at the 2010 IASA Annual Conference and Business Show this week in Grapevine, Texas, highlighted how the millennial generation's exploding use of social media is spurring more carriers to leverage tools like Facebook, LinkedIn and other social networks to engage prospect and customers. While panelists encouraged carriers to leverage social networking tools for marketing and communications, they expressed the need for caution and corporate governance when it comes to using the tools as a part of claims, underwriting, and human resources recruitment business practices, and interactions with producers. (A previous Oracle Insurance blog entry by my colleague Susan Keuer noted that social networking and its impact on the underwriting process was also a hot topic at the recent AHOU conference.) Speaking of the millennial generation, IASA announced a new scholarship program and awarded three scholarships during the association's conference this week. The IASA Insurance Industry Collegiate Scholarship Program awards $2,000 scholarships to students in their second or third year of college who are studying an insurance-related field at a four-year college or university. The IASA scholarship committee is co-chaired by Wendy Gibson, vice president of business development for Oracle Insurance. Gibson, a long time IASA volunteer, is completing her second term on IASA's volunteer management team as vice president of industry relations. Helen Pitts is senior product marketing manager for Oracle Insurance.

  • Don’t be a dinosaur. Use Calendar Tree!

    - by jamiet
    If one spends long enough in my company one will likely eventually have to listen to me bark on about subscribable calendars. I was banging on about them way back in 2009, I’ve cajoled SQLBits into providing one, provided one myself for the World Cup, and opined that they could be transformative for the delivery of BI. I believe subscribable calendars can change the world but have never been good at elucidating why I thought so, for that reason I always direct people to read a blog by Scott Adams (yes, the guy who draws Dilbert) entitled Calendar as Filter. In that blog post Scott writes: I think the family calendar is the organizing principle into which all external information should flow. I want the kids' school schedules for sports and plays and even lunch choices to automatically flow into the home calendar. Everything you do has a time dimension. If you are looking for a new home, the open houses are on certain dates, and certain houses that fit your needs are open at certain times. If you are shopping for some particular good, you often need to know the store hours. Your calendar needs to know your shopping list and preferences so it can suggest good times to do certain things I think the biggest software revolution of the future is that the calendar will be the organizing filter for most of the information flowing into your life. You think you are bombarded with too much information every day, but in reality it is just the timing of the information that is wrong. Once the calendar becomes the organizing paradigm and filter, it won't seem as if there is so much. I wholly agree and hence was delighted to discover (via the Hanselminutes podcast) that Scott has a startup called CalendarTree.com whose raison d’etre is to solve this very problem. What better way to describe a Scott Adams startup than with a Scott Adams comic: I implore you to check out Calendar Tree and make the world a tiny bit better by using it to share any information that has a time dimension to it. Don’t be a dinosaur, use Calendar tree! @Jamiet

  • Obama’s win and the geeky stuff behind his success

    - by Gopinath
    Mr. Obama is elected as President of United States for the second term with a great majority. Here are few geeky bytes associated with Mr.Obama’s success and the world records he set up Obama Creates New Records on Twitter and Facebook – Just after winning the race for president, Barak Obama setup world records on Twitter & Facebook. His tweet “Four more years” re-tweeted more than 770K times and his Facebook post received 3.8 million likes. Twitter Kills the Fail Whale, One Tweet at a Time – Twitter handled insane user loads with millions of tweets related to election and proved that it’s platform is now more robust than ever. In a post on the company’s engineering blog, Twitter said people sent 31 million election-related tweets on Tuesday alone. From 8:11 p.m. to 9:11 p.m. P.S.T., Twitter processed an average 9,965 tweets per second, with a one-second peak of 15,107 tweets per second at 8:20 p.m., the company said. Obama’s win a big vindication for Nate Silver, king of the quants – Nate Silver, a statistician and blogger was spot on in predicting Obama’s win many weeks. He did not depend on astrology or surveys to predict Obama’s success. He used big data and statistical analysis to project votes. CNET says “Despite some incredulous political pundits, the FiveThirtyEight statistician appears to have correctly predicted the winner in all 50 states in the presidential election” Inside the Secret World of the Data Crunchers Who Helped Obama Win – Team Obama used big data and analytical systems to win the elections!! Barack Obama Goes On Reddit For Last Campaign Stop Of Political Career – Reditt is getting a lot of Obama’s attention these days. He is quite often stopping by Reditt to say hi to the nerds & geeks hanging out there. His chat with nerds on Reddit has paid rich dividends.

  • SQLAuthority News – Download Whitepaper – A Case Study on “Hekaton” against RPM – SQL Server 2014 CTP1

    - by Pinal Dave
    In this new world of social media, apps and mobile devices, we are all now getting impatient. Automatic updates have spoiled few of our habits. When a new feature is released everybody wants to immediately adopt the feature and start using it. Though this is true in the world of apps and smart phones, but it is still not possible in the developer’s world. When new features are around, before we start using it, we need to spend quite a lots of time to understand it and test it. Once we are sold on the feature we refer the feature to our manager and eventually the entire organization makes decisions on upgrading to use the new feature. Similarly, when the new feature of In-Memory OLTP was announced, pretty much every SQL Server DBA wanted to implement that on their server. Through the implementation of the feature is not hard, it is not that easy as well. One has to do proper research about their own environment and workload before implementing this feature. Microsoft has recently released a Case Study on In-Memory OLTP feature. Here is the abstract from the white paper itself. I/O latch can cause session delays that impact application performance. This white paper describes the procedures and common I/O latch issues when migrating to Hekaton in SQL Server 2014. It also includes challenges that occurred during the migration and the performance analysis at different stages.  If you are going to implement In-Memory OLTP database, this is a good case study to refer. Download white paper from here.

  • Future direction for a developer who is expert in latest software technologies…

    - by Muaz Khan
    Hi everyone, If a (new-coming) developer that learns latest technologies as well as can develop amazing stuff with those technologies and did Bachelors in Arts (BA). So what ’ll be the future of this kind of developer? I meant did he can get good job without degree? I think (but it is the universal truth that) no one (org or company) permit these kind of developers to join them because degree is must for job!! I’m worried about why the world depends upon degree? Why degree is necessary for good job? If a developer has a good experience, why he cannot be able to get good job without degree? What is the future of developer that starts his life as a freelancer and learns everything himself with the help of online available resources? Why companies prerequisite the degree for a good job? A developer without degree can be expert than that who have a degree of MSC etc. Because in 3rd world countries especially Pakistan, a BSC level student taught VB6 and the MSC level student learns C/C++. The common student doesn’t know about latest innovative technologies and he think that the world is depending upon VB6 or C/C++. What is the comparison of that students with a developer that do Bachelors in Arts but know (and can do well with) latest technologies.

  • Does HTML 5 &ldquo;Rich vs. Reach&rdquo; a False Choice?

    - by andrewbrust
    The competition between the Web and proprietary rich platforms, including Windows, Mac OS, iPhone/iPad, Adobe’s Flash/AIR and Microsoft’s Silverlight, is not new. But with the emergence of HTML 5 and imminent support for it in the next release of the major Web browsers, the battle is heating up. And with the announcements made Wednesday at Google's I/O conference, it's getting kicked up yet another notch. The impact of this platform battle on companies in the media and advertising world, and the developers who serve them, is significant. The most prominent question is whether video and rich media online will shift towards pure HTML and away from plug-ins like Flash and Silverlight. In fact, certain features in HTML 5 make it suitable for development for line of business applications as well, further threatening those plug-in technologies. So what's the deal? Is this real or hype? To answer that question, I've done my own research into HTML 5's features and talked to several media-focused, New York area developers to get their opinions. I present my findings to you in this post. Before bearing down into HTML 5 specifics and practitioners’ quotes, let's set the context. To understand what HTML 5 can do, take a look at this video of Sports Illustrated’s HTML 5 prototype. This should start to get you bought into the idea that HTML 5 could be a game-changer. Next, if you happen to have installed the beta version of Google's Chrome 5 browser, take a look at the page linked to below, and in that page, click on any of the game thumbnails to see what's possible, without a plug-in, in this brave new world. (Note, although the instructions for each game tell you to press the A key to start, press the Z key instead.). Here's the link: http://www.kesiev.com/akihabara As an adjunct to what's enabled by HTML 5, consider the various transforms that are part of CSS 3. If you're running Safari as your browser, the following link will showcase this live; if not, you'll see a bitmap that will give you an idea of what's possible: http://webkit.org/blog/386/3d-transforms Are you starting to get the picture (literally)? What has up until now required browser plug-ins and other patches to HTML, most typically Flash, will soon be renderable, natively, in all major browsers. Moreover, it's looking likely that developers will be able to deliver such content and experiences in these browsers using one base of markup and script code (using straight JavaScript and/or jQuery), without resorting to browser-specific code and workarounds. If you're skeptical of this, I wouldn't blame you, especially with respect to Microsoft's Internet Explorer. However, i can tell you with confidence that even Microsoft is dedicated to full-on HTML 5 support in version 9 of that browser, which is currently under development. So what’s new in HTML 5, specifically, that makes sites like this possible?  The specification documents go into deep detail, and there’s no sense in rehashing them here, but a summary is probably in order.   Here is a non-authoritative, but useful, list of the major new feature areas in HTML 5: 2D drawing capabilities and 3D transforms. 2D drawing instructions can be embedded statically into a Web page; application interactivity and animation can be achieved through script.  As mentioned above, 3D transforms are technically part of version 3 of the CSS (Cascading Style Sheets) spec, rather than HTML 5, but they can nonetheless be thought of as part of the bundle.  They allow for rendering of 3D images and animations that, together with 2D drawing, make HTML-based games much more feasible than they are presently, as the links above demonstrate. Embedded audio and video. A media player can appear directly in a rendered Web page, using HTML markup and no plug-ins. Alternately, player controls can be hidden and the content can play automatically. Major enhancements to form-based input. This includes such things as specification of required fields, embedding of text “hints” into a control, limiting valid input on a field to dates, email addresses or a list of values.  There’s more to this, but the gist is that line-of-business applications, with complicated input and data validation, are supported directly Offline caching, local storage and client-side SQL database. These facilities allow Web applications to function more like native apps, even if no internet connection is available. User-defined data. Data (or metadata – data about data) can easily be embedded statically and/or retrieved and updated with Javascript code. This avoids having to embed that data in a separate file, or within script code. Taken together, these features position HTML to compete with, and perhaps overtake, Adobe’s Flash/AIR (and Microsoft’s Silverlight) as a viable Web platform for media, RIAs (rich internet applications – apps that function more like desktop software than Web sites) and interactive Web content, including games. What do players in the media world think about this?  From the embedded video above, we know what Sports Illustrated (and, therefore, Time Warner) think.  Hulu, the major Internet site for broadcast TV content, is on record as saying HTML5 video does not pass muster with them, at least not yet.  YouTube, on the other hand, already has an experimental HTML 5-based version of their site.  TechCrunch has reported that NetFlix is flirting with HTML 5 too, especially as it pertains to embedded browsers in TV-based devices.  And the New York Times’ Web site now embeds some video clips without resorting to Flash.  They have to – otherwise iPhone, iPod Touch and iPad users couldn’t see them in the Mobile Safari browser. What do media-focused developers think about all this?  I talked to several to get their opinions. Michael Pinto is CEO and Founder of Very Memorable Design whose primary focus has been to help marketing directors get traction online.  The firm’s client roster includes the likes Time, Inc., Scholastic and PBS.  Pinto predicts that “More and more microsites that were done entirely in Flash will be done more and more using jQuery. I can also see slideshows and video now being done without Flash. However if you needed to create a game or highly interactive activity Flash would still be the way to go for the web.” A dissenting view comes from Jesse Erlbaum, CEO of The Erlbaum Group, LLC, which serves numerous clients in the magazine publishing sector.  When I asked Erlbaum whether he thought HTML 5 and jQuery/JavaScript would steal significant market share from Flash, he responded “Not at all!  In particular, not for media and advertising customers!  These sectors are not generally in the business of making highly functional applications, which is the one place where HTML5/jQuery/etc really shines.” Ironically, Pinto’s firm is a heavy user of Flash for its projects and Erlbaum’s develops atop the “LAMP” (Linux, Apache, MySQL and PHP/Perl) stack.  For whatever reason, each firm seems to see the other’s toolset as a more viable choice.  But both agree that the developer tool story around HTML 5 is deficient.  Pinto explains “What’s lost with [HTML 5 and Javascript] techniques is that there isn’t a single widely favored easy-to-use tool of choice for authoring. So with Flash you can get up and running right away and not worry about what is different from one browser to the next.“  Erlbaum agrees, saying: “HTML5/Javascript lacks a sophisticated integrated development environment (IDE) which is an essential part of Flash.  If what someone is trying to make is primarily animation, it's a waste of time…to do this in Javascript.  It can be done much more easily in Flash, and with greater cross-browser compatibility and consistency due to the ubiquity of Flash.” Adobe (maker of Flash since its 2005 acquisition of Macromedia) likely agrees.  And for better or worse, they’ve decided to address this shortcoming of HTML 5, even at risk of diminishing their Flash platfrom. Yesterday Adobe announced that their hugely popular Deamweaver Web design authoring tool would directly support HTML 5 and CSS 3 development.  In fact, the Adobe Dreamweaver CS5 HTML5 Pack is downloadable now from Adobe Labs. Maybe Adobe is bowing to pressure from ardent Web professionals like Scott Kellum, Lead Designer at Channel V Media,  a digital and offline branding firm, serving the media and marketing sectors, among others.  Kellum told me that HTML 5 “…will definitely move people away from Flash. It has many of the same functionalities with faster load times and better accessibility. HTML5 will help Flash as well: with the new caching methods you can now even run Flash apps offline.” Although all three Web developers I interviewed would agree that Flash is still required for more sophisticated applications, Kellum seems to have put his finger on why HTML 5 may nonetheless dominate.  In his view, much of the Web development out there has little need for high-end capabilities: “Most people want to add a little punch to a navigation bar or some video and now you can get the biggest bang for your buck with HTML5, CSS3 and Javascript.” I’ve already mentioned that Google’s ongoing I/O conference, at the Moscone West center in San Francisco, is driving the HTML 5 news cycle, big time.  And Google made many announcements of their own, including the open sourcing of their VP8 video codec, new enterprise-oriented capabilities for its App Engine cloud offering, and the creation of the Chrome Web Store, which the company says will make it easier to find and “install” Web applications, in a fashion similar to  the way users procure native apps on various mobile platforms. HTML 5 looks to be disruptive, especially to the media world.  And even if the technology ends up disappointing, the chatter around it alone is causing big changes in the technology world.  If the richness it promises delivers, then magazine publishers and non-text digital advertisers may indeed have a platform for creating compelling content that loads quickly, is standards-based and will render identically in (the newest versions of) all major Web browsers.  Can this development in the digital arena save the titans of the print world?  I can’t predict, but it’s going to be fun to watch, and the competitive innovation from all players in both industries will likely be immense.

  • How do you deal with translating theory into practice?

    - by Mr. Shickadance
    Hello all! Being a computer scientist in a research field I am often tasked with working alongside professionals outside of the software domain (think math people, electrical engineer etc), and then translating their theories and ideas into real-world implementations. I often find it difficult when they present a theoretical problem which appears to be somewhat disconnected from reality. I am not saying that the theory is bogus, only that it is difficult to translate into real-world situations. For example, recently I have been working with software defined radios. We are exploring many different areas, but often the math specialists in my group would present a problem which is heavily grounded in theory (signal processing, physics, whatever). I often struggle at times where it is hard to draw direct parallels between the theory and the real-world implementation that I need to develop. Say we are working on an energy detector, the theory person in my group would say "you need to measure the noise variance with no signal present." This leads me to think "how the hell do I isolate noise from a signal in reality?" There are many examples, but I hope you see where I am going. So, my question is how does one deal with implementation of theoretical concepts when the theory seems detached from reality? Or at least when the connections are not so clear. Or perhaps, the person with the 'theory' may be ignorant of real restrictions? Note: I found this to be a hard question to ask - hopefully you are following me. If you have suggestions on how I could improve it, by all means let me know! Thanks for looking! EDIT: To be a bit more clear, I understand in situations like this that I must learn that specific domain myself to an extent (i.e. signal processing), but I am more concerned with when those theoretical concepts do not appear to be as grounded in practice as one would like.

  • Switching from Java/Java EE career path to C POS path?

    - by Muhammad
    I am a Java/Java EE Developer with about 3 years in this field. I like low-level programming so much... I favor back-end code over front-end. I've a knowledge in C and know little about C++. I got an offer to work with C in Point-of-Sale Payment terminals. I don't know much about how POS works (IDE/toolsets, etc). although I have a payment experience (ISO8583, etc...) I need you own opinion from Switching from the Java's High-level world to POS low-level world Although I love low-level world, but I am afraid from not being found what I seek.. I know programmers are not measured by the tools they use (including prog. langs.) but with their minds. I need your opinions of: Is programming POS terminals in C is an interesting thing, or I'll find myself doing usual code-writing job? (especially I am about to switch my whole career path). I find myself writing an elegant code in Java (like: Sobat http://code.google.com/p/sobat/) a code where I find myself in... So do I'll find the same thing in POS C? or It will all about Libraries that I'll call to finish my work?! Lastly, does this thing worse adventure with my current career (stability, conference, etc.. )? (as I currently don't think to move to a new job) Thanks.

  • Improving SpriteBatch performance for tiles

    - by Richard Rast
    I realize this is a variation on what has got to be a common question, but after reading several (good answers) I'm no closer to a solution here. So here's my situation: I'm making a 2D game which has (among some other things) a tiled world, and so, drawing this world implies drawing a jillion tiles each frame (depending on resolution: it's roughly a 64x32 tile with some transparency). Now I want the user to be able to maximize the game (or fullscreen mode, actually, as its a bit more efficient) and instead of scaling textures (bleagh) this will just allow lots and lots of tiles to be shown at once. Which is great! But it turns out this makes upward of 2000 tiles on the screen each time, and this is framerate-limiting (I've commented out enough other parts of the game to make sure this is the bottleneck). It gets worse if I use multiple source rectangles on the same texture (I use a tilesheet; I believe changing textures entirely makes things worse), or if you tint the tiles, or whatever. So, the general question is this: What are some general methods for improving the drawing of thousands of repetitive sprites? Answers pertaining to XNA's SpriteBatch would be helpful but I'm equally happy with general theory. Also, any tricks pertaining to this situation in particular (drawing a tiled world efficiently) are also welcome. I really do want to draw all of them, though, and I need the SpriteMode.BackToFront to be active, because

  • Get to Know a Candidate (15 of 25): Jerry White&ndash;Socialist Equality Party

    - by Brian Lanham
    DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. White (born Jerome White) is an American politician and journalist, reporting for the World Socialist Web Site.  White's Presidential campaign keeps four core components: * International unity in the working class * Social equality * Opposition to imperialist militarism and assault on democratic rights * Opposition to the political subordination of the working class to the Democrats and Republicans The White-Scherrer ticket is currently undergoing a review by the Wisconsin election committee concerning the ballot listing of the party for the 2012 Presidential elections. White has visited Canada, Germany, and Sri Lanka to campaign for socialism and an international working class movement. The Socialist Equality Party (SEP) is a Trotskyist political party in the United States, one of several Socialist Equality Parties around the world affiliated to the International Committee of the Fourth International (ICFI). The ICFI publishes daily news articles, perspectives and commentaries on the World Socialist Web Site. The party held public conferences in 2009 and 2010. It led an inquiry into utility shutoffs in Detroit, Michigan earlier in 2010, after which it launched a Committee Against Utility Shutoffs. Recently it sent reporters to West Virginia to report on the Upper Big Branch Mine disaster and the way that Massey Energy has treated its workers. It also sent reporters to the Gulf Coast to report on the Deepwater Horizon oil spill. In addition, it has participated in elections with the aim of opposing the American occupation of Iraq and building a mass socialist party with an international perspective. Despite having been active for over a decade, the Socialist Equality Party held its founding congress in 2008, where it adopted a statement of principles and a historical document. White has Ballot Access in: CO, LA, WI Learn more about Jerry White and Socialist Equality Party on Wikipedia
