  • CFOs: Do You Have a Playbook for Growth?

    - by Oracle Accelerate for Midsize Companies
    by Jim Lein, Oracle Midsize Programs In most global markets, CFOs are optimistic about their company's growth opportunities. Deloitte's CFO Signals Report, "Time to Accelerate" found that: In the U.K. business optimism is at its highest level in three-and-a-half years Optimism in North America rose from a strong +42% last quarter (Q2 to Q3 2013) to an even stronger +54%. The inaugural Southeast Asia survey, 44% of CFOs reported a positive outlook despite worries over the Chinese economy and political uncertainty. Sustainable and profitable business growth doesn't usually happen by accident. Company's need a playbook for growth that's owned by the CFO. And today, that playbook must leverage the six enabling technologies--Social, Big Data, Mobile, Cloud, Analytics, and The Internet of Things (or, as Oracle president Mark Hurd explains, "The Internet of the People"). On Monday June 9 at  2:00 pm Eastern, CFO.com is hosting a webcast, "The CFO Playbook on Growth: How CFOs Can Boost Efficiency and Performance with Automation".

  • Gnome-shell fails to load on 12.10

    - by Githlar
    I'm usually the one answering questions, but in this I'm throughly stumped! My Setup: Ubuntu 12.10 (Dist upgrade form 12.04) ATI M96 [Mobility Radeon HD 4650] Upon the first installation of 12.10 I had all kinds of issues getting the Legacy ATI drivers to install (I guess the source for the drivers isn't kosher with kernel 3.5). So, I added the repository ppa:makson96/fglrx - which has a version of the ATI source patched to work with kernel 3.5. After installation of fglrx-legacy from that PPA, gnome-shell and all my graphics work fine... until today. The Problem I unsuspended my computer today and the screen was black (not off, the black from the gnome lock screen). I'd move my mouse/hit a key and the background would flash and then it'd go back to black. Restarted via VT1 Logged into Gnome (gnome-shell) session, but no gnome-shell! Investigation: First, I went to VT1 and tried export DISPLAY=:0;gnome-shell --replace. It appeared to work fine, switch back to X and nothing. Went back to VT1 and saw this error message: JS ERROR: !!! Exception was: TypeError: Object 0x7fc748129c30 is not a subclass of (null), it's a xO JS ERROR: !!! message = '"Object 0x7fc748129c30 is not a subclass of (null), it's a xO"' JS ERROR: !!! fileName = '"/usr/share/gnome-shell/js/ui/tweener.js"' JS ERROR: !!! lineNumber = '218' JS ERROR: !!! stack = '"()@/usr/share/gnome-shell/js/ui/tweener.js:218 wrapper()@/usr/share/gjs-1.0/lang.js:204 ()@/usr/share/gjs-1.0/lang.js:145 ()@/usr/share/gjs-1.0/lang.js:239 init()@/usr/share/gnome-shell/js/ui/tweener.js:49 init()@/usr/share/gnome-shell/js/ui/environment.js:96 @<main>:1 "' Window manager warning: Log level 32: Execution of main.js threw exception: TypeError: Object 0x7fc748129c30 is not a subclass of (null), it's a xO Note: Everywhere it says "it's a xO", xO is actually garbled and changes every time (I'm thinking memory corruption?) This error is thrown by line 96 of /usr/share/gnome-shell/js/ui/environment.js: tweener.Init() Did a purge of fglrx-legacy, reboot, reinstall fglrx-legacy, reboot... same thing. Did a ppa-purge of ppa:gnome3-team/gnome3, and reinstalled gnome-shell and ubuntu-desktop from the standard repositores... same thing. I'm really at a loss here.

  • Is Visual Source Safe (The latest Version) really that bad? Why? What's the Best Alternative? Why? [closed]

    - by hanzolo
    Over the years I've constantly heard horror stories, had people say "Real Programmers Dont Use VSS", and so on. BUT, then in the workplace I've worked at two companies, one, a very well known public facing high traffic website, and another high end Financial Services "Web-Based" hosted solution catering to some very large, very well known companies, which is where I currently Reside and everything's working just fine (KNOCK KNOCK!!). I'm constantly interfacing with EXTREMELY Old technology with some of these financial institutions.. OLD LIKE YOU WOULDN'T BELIEVE.. which leads me to the conclusion that if it works "LEAVE IT", and that maybe there's some value in old technology? at least enough value to overrule a rewrite!? right?? Is there something fundamentally flawed with the underlying technology that VSS uses? I have a feeling that if i said "someone said VSS Sucks" they would beg to differ, most likely give me this look like i dont know -ish, and I'd never gain back their respect and my credibility (well, that'll be hard to blow.. lol), BUT, give me an argument that I can take to someone whose been coding for 30 years, that builds Platforms that leverage current technology (.NET 3.5 / SQL 2008 R2 ), write's their own ORM with scaffolding and is able to provide a quality platform that supports thousands of concurrent users on a multi-tenant hosted solution, and does not agree with any benefits from having Source Control Integrated, and yet uses the Infamous Visual Source Safe. I have extensive experience with TFS up to 2010, and honestly I think it's great when a team (beyond developers) can embrace it. I've worked side by side with someone whose a die hard SVN'r and from a purist standpoint, I see the beauty in it (I need a bit more, out of my SS, but it surely suffices). So, why are such smarties not running away from Visual Source Safe? surely if it was so bad, it would've have been realized by now, and I would not be sitting here with this simple old, Check In, Check Out, Version Resistant, Label Intensive system. But here I am... I would love to drop an argument that would be the end all argument, but if it's a matter of opinion and personal experience, there seems to be too much leeway for keeping VSS. UPDATE: I guess the best case is to have the VSS supporters check other people's experiences and draw from that until we (please no) experience the breaking factor ourselves. Until then, i wont be engaging in a discussion to migrate off of VSS.. UPDATE 11-2012: So i was able to convince everyone at my work place that since MS is sun downing Visual Source Safe it might be time to migrate over to TFS. I was able to convince them and have recently upgraded our team to Visual Studio 2012 and TFS 2012. The migration was fairly painless, had to run analyze.exe which found a bunch of errors (not sure they'll ever affect the project) and then manually run the VSSConverter.exe. Again, painless, except it took 16 hours to migrate 5 years worth of everything.. and now we're on TFS.. much more integrated.. much more cooler.. so all in all, VSS served it's purpose for years without hick-up. There were no horror stories and Visual Source Save as source control worked just fine. so to all the nay sayers (me included). there's nothing wrong with using VSS. i wouldnt start a new project with it, and i would definitely consider migrating to TFS. (it's really not super difficult and a new "wizard" type converter is due out any day now so migrating should be painless). But from my experience, it worked just fine and got the job done.

  • The Social Content Conundrum

    - by Mike Stiles
    Here’s the social content conundrum: people who are not entertainers are being asked to entertain. Despite a world of skilled MBAs, marketing savants, technological innovators, analysts, social strategists and consultants, every development in social for brands keeps boomeranging right back to the same unavoidable truth. Success hinges on having content creators who know how to entertain the target audience. You can’t make this all about business-processes. You can’t make this all about technology, though data is critical and helps inform content. This is about having human beings who know the audience, know what they’d love to see, and can create the magic that will draw and hold them. Since showing up in the News Feed is critical for exposition and engagement, and since social ads primarily serve to amplify content that’s performing well, I’m comfortable saying content creators are becoming exponentially recruited and valued. They will no longer be commodities. They’ll be your stars. Social has fundamentally changed the relationship between brand and consumer. No longer can the customer be told to sit down, shut up, and listen to our ads. It’s now all about what consumers are willing to watch or read. Their patience for subjecting themselves to material they aren’t interested in is waning. Therefore, brands must now be producers of entertainment and information content, not merely placers of ads within someone else’s content. Social has given you a huge stage, with an audience sitting out there waiting to see what you’re going to do. What are you putting on that stage? For most corporate environments, entertaining is alien. It’s risky and subjective. Most operate around two foundational principles: control and fear. To entertain and inform with branded content, some control has to go. You control the product. Past that, control is being transferred into the hands of the consumer. The “fear first” culture also has to yield. If you strive to never make waves, you will move absolutely nothing. Because most corporations don’t house entertainers, they must be found then trusted. They’re usually a little weird. The ideas they’ll bring may seem “out there.” But like any business professional, they’ve gone through the training and experiences that make them uniquely good at what they do, even if you don’t quite understand them. It’s okay. It’s what the audience thinks that matters. Get it right, and you’ll be generating one ambassador after another who’s proud to be identified with the brand and will regularly consume and share your content. Entertainment entities are able to shape our culture and succeed beyond their wildest dreams by being beholden to one thing…what the public likes and wants. When brands put the same emphasis on crowd-pleasing content, they too will enjoy brand fame the likes of which they’ve never seen. The stage is yours. Now get out there and go for that applause.

  • Optimal Data Structure for our own API

    - by vermiculus
    I'm in the early stages of writing an Emacs major mode for the Stack Exchange network; if you use Emacs regularly, this will benefit you in the end. In order to minimize the number of calls made to Stack Exchange's API (capped at 10000 per IP per day) and to just be a generally responsible citizen, I want to cache the information I receive from the network and store it in memory, waiting to be accessed again. I'm really stuck as to what data structure to store this information in. Obviously, it is going to be a list. However, as with any data structure, the choice must be determined by what data is being stored and what how it will be accessed. What, I would like to be able to store all of this information in a single symbol such as stack-api/cache. So, without further ado, stack-api/cache is a list of conses keyed by last update: `(<csite> <csite> <csite>) where <csite> would be (1362501715 . <site>) At this point, all we've done is define a simple association list. Of course, we must go deeper. Each <site> is a list of the API parameter (unique) followed by a list questions: `("codereview" <cquestion> <cquestion> <cquestion>) Each <cquestion> is, you guessed it, a cons of questions with their last update time: `(1362501715 <question>) (1362501720 . <question>) <question> is a cons of a question structure and a list of answers (again, consed with their last update time): `(<question-structure> <canswer> <canswer> <canswer> and ` `(1362501715 . <answer-structure>) This data structure is likely most accurately described as a tree, but I don't know if there's a better way to do this considering the language, Emacs Lisp (which isn't all that different from the Lisp you know and love at all). The explicit conses are likely unnecessary, but it helps my brain wrap around it better. I'm pretty sure a <csite>, for example, would just turn into (<epoch-time> <api-param> <cquestion> <cquestion> ...) Concerns: Does storing data in a potentially huge structure like this have any performance trade-offs for the system? I would like to avoid storing extraneous data, but I've done what I could and I don't think the dataset is that large in the first place (for normal use) since it's all just human-readable text in reasonable proportion. (I'm planning on culling old data using the times at the head of the list; each inherits its last-update time from its children and so-on down the tree. To what extent this cull should take place: I'm not sure.) Does storing data like this have any performance trade-offs for that which must use it? That is, will set and retrieve operations suffer from the size of the list? Do you have any other suggestions as to what a better structure might look like?

  • Concurrent Affairs

    - by Tony Davis
    I once wrote an editorial, multi-core mania, on the conundrum of ever-increasing numbers of processor cores, but without the concurrent programming techniques to get anywhere near exploiting their performance potential. I came to the.controversial.conclusion that, while the problem loomed for all procedural languages, it was not a big issue for the vast majority of programmers. Two years later, I still think most programmers don't concern themselves overly with this issue, but I do think that's a bigger problem than I originally implied. Firstly, is the performance boost from writing code that can fully exploit all available cores worth the cost of the additional programming complexity? Right now, with quad-core processors that, at best, can make our programs four times faster, the answer is still no for many applications. But what happens in a few years, as the number of cores grows to 100 or even 1000? At this point, it becomes very hard to ignore the potential gains from exploiting concurrency. Possibly, I was optimistic to assume that, by the time we have 100-core processors, and most applications really needed to exploit them, some technology would be around to allow us to do so with relative ease. The ideal solution would be one that allows programmers to forget about the problem, in much the same way that garbage collection removed the need to worry too much about memory allocation. From all I can find on the topic, though, there is only a remote likelihood that we'll ever have a compiler that takes a program written in a single-threaded style and "auto-magically" converts it into an efficient, correct, multi-threaded program. At the same time, it seems clear that what is currently the most common solution, multi-threaded programming with shared memory, is unsustainable. As soon as a piece of state can be changed by a different thread of execution, the potential number of execution paths through your program grows exponentially with the number of threads. If you have two threads, each executing n instructions, then there are 2^n possible "interleavings" of those instructions. Of course, many of those interleavings will have identical behavior, but several won't. Not only does this make understanding how a program works an order of magnitude harder, but it will also result in irreproducible, non-deterministic, bugs. And of course, the problem will be many times worse when you have a hundred or a thousand threads. So what is the answer? All of the possible alternatives require a change in the way we write programs and, currently, seem to be plagued by performance issues. Software transactional memory (STM) applies the ideas of database transactions, and optimistic concurrency control, to memory. However, working out how to break down your program into sufficiently small transactions, so as to avoid contention issues, isn't easy. Another approach is concurrency with actors, where instead of having threads share memory, each thread runs in complete isolation, and communicates with others by passing messages. It simplifies concurrent programs but still has performance issues, if the threads need to operate on the same large piece of data. There are doubtless other possible solutions that I haven't mentioned, and I would love to know to what extent you, as a developer, are considering the problem of multi-core concurrency, what solution you currently favor, and why. Cheers, Tony.

  • Career-Defining Moments

    - by Robz / Fervent Coder
    Originally posted on: http://geekswithblogs.net/robz/archive/2013/06/25/career-defining-moments.aspx Fear holds us back from many things. A little fear is healthy, but don’t let it overwhelm you into missing opportunities. In every career there is a moment when you can either step forward and define yourself, or sit down and regret it later. Why do we hold back: is it fear, constraints, family concerns, or that we simply can't do it? I think in many cases it comes to the unknown, and we are good at fearing the unknown. Some people hold back because they are fearful of what they don’t know. Some hold back because they are fearful of learning new things. Some hold back simply because to take on a new challenge it means they have to give something else up. The phrase sometimes used is “It’s the devil you know versus the one you don’t.” That fear sometimes allows us to miss great opportunities. In many people’s case it is the opportunity to go into business for yourself, to start something that never existed. Most hold back hear for a fear of failing. We’ve all heard the phrase “What would you do if you knew you couldn’t fail?”, which is intended to get people to think about the opportunities they might create. A better term I heard recently on the Ruby Rogues podcast was “What would be worth doing even if you knew you were going to fail?” I think that wording suits the intent better. If you knew (or thought) going in that you were going to fail and you didn’t care, it would open you up to the possibility of paying more attention to the journey and not the outcome. In my case it is a fear of acceptance. I am fearful that I may not learn what I need to learn or may not do a good enough job to be accepted. At the same time that fear drives me and makes me want to leap forward. Some folks would define this as “The Flinch”. I’m learning Ruby and Puppet right now. I have limited experience with both, limited to the degree it scares me some that I don’t know much about either. Okay, it scares me quite a bit! Some people’s defining moment might be going to work for Microsoft. All of you who know me know that I am in love with automation, from low-tech to high-tech automation. So for me, my “mecca” is a little different in that regard. Awhile back I sat down and defined where I wanted my career to go and it had to do more with DevOps, defined as applying developer practices to system administration operations (I could not find this definition when I searched). It’s an area that interests me and why I really want to expand chocolatey into something more awesome. I want to see Windows be as automatable and awesome as other operating systems that are out there. Back to the career-defining moment. Sometimes these moments only come once in a lifetime. The key is to recognize when you are in one of these moments and step back to evaluate it before choosing to dive in head first. So I am about to embark on what I define as one of these “moments.”  On July 1st I will be joining Puppet Labs and working to help make the Windows automation experience rock solid! I’m both scared and excited about the opportunity!

  • Upgrade to Xubuntu 13.10 - Saucy Salamander

    As a common 'fashion' it is possible to upgrade an existing installation of Ubuntu or one of its derivates every six months. Of course, you might opt-in for the adventure and directly keep your system always on the latest version (including alphas and betas), or you might like to play safe and stay on the long-term support (LTS) versions which are updated every two years only. As for me, I'd like to jump from release to release on my main desktop machine. And since 17th October Saucy Salamander or also known as Ubuntu 13.10 has been released for general use. The following paragraphs document the steps I went in order to upgrade my system to the recent version. Don't worry about the fact that I'm actually using Xubuntu. It's mainly a flavoured version of Ubuntu running Xfce 4.10 as default X Window manager. Well, I have Gnome and LXDE on the same system... just out of couriosity. Preparing the system Before you think about upgrading you have to ensure that your current system is running on the latest packages. This can be done easily via a terminal like so: $ sudo apt-get update && sudo apt-get -y dist-upgrade --fix-missing Next, we are going to initiate the upgrade itself: $ sudo update-manager As a result the graphical Software Updater should inform you that a newer version of Ubuntu is available for installation. Ubuntu's Software Updater informs you whether an upgrade is available Running the upgrade After clicking 'Upgrade...' you will be presented with information about the new version. Details about Ubuntu 13.10 (Saucy Salamander) Simply continue with the procedure and your system will be analysed for the next steps. Analysing the existing system and preparing the actual upgrade to 13.10 Next, we are at the point of no return. Last confirmation dialog before having a coffee break while your machine is occupied to download the necessary packages. Not the best bandwidth at hand after all... yours might be faster. Are you really sure that you want to start the upgrade? Let's go and have fun! Anyway, bye bye Raring Ringtail and Welcome Saucy Salamander! In case that you added any additional repositories like Medibuntu or PPAs you will be informed that they are going to be disabled during the upgrade and they might require some manual intervention after completion. Ubuntu is playing safe and third party repositories are disabled during the upgrade Well, depending on your internet bandwidth this might take something between a couple of minutes and some hours to download all the packages and then trigger the actual installation process. In my case I left my PC unattended during the night. Time to reboot Finally, it's time to restart your system and see what's going to happen... In my case absolutely nothing unexpected. The system booted the new kernel 3.11.0 as usual and I was greeted by a new login screen. Honestly, 'same' system as before - which is good and I love that fact of consistency - and I can continue to work productively. And also Software Updater confirms that we just had a painless upgrade: System is running Ubuntu 13.10 - Saucy Salamander - and up to date See you in six months again... ;-) Post-scriptum In case that you would to upgrade to the latest development version of Ubuntu, run the following command in a console: $ sudo update-manager -d And repeat all steps as described above.

  • No Customer Left Behind

    - by Kathryn Perry
    A guest post by David Vap, Group Vice President, Oracle Applications Product Development What does customer experience mean to you? Is it a strategy for your executives? A new buzz word and marketing term? A bunch of CRM technology with social software added on? For me, customer experience is a customer-centric worldview that produces a deeper understanding of your business and what it takes to achieve sustainable, differentiated success. It requires you to prioritize and examine the journey your customers are on with your brand, so you can answer the question, "How can we drive greater value for our business by delivering a better customer experience?" Businesses that embrace a customer-centric worldview understand their business at a much deeper level than most. They know who their customers are, what their value is, what they do, what they say, what they want, and ultimately what that means to their business. "Why Isn't Everyone Doing It?" We're all consumers who have our own experiences with many brands. Good or bad, some of those experiences stay with us. So viscerally we understand the concept of customer experience from the stories we share. One that stands out in my mind happened as I was preparing to leave for a 12-month job assignment in Europe. I wanted to put my cable television subscription on hold. I wasn't leaving for another vendor. I wasn't upset. I just had a situation where it made sense to put my $180 per month account on pause until I returned. Unfortunately, there was no way for this cable company to acknowledge that I was a loyal customer with a logical request - and to respond accordingly. So, ultimately, they lost my business. Research shows us that it costs six to seven times more to acquire a new customer than to retain an existing one. Heavily funding the efforts of getting new customers and underfunding the efforts of serving the needs of your existing (who are your greatest advocates) is a vicious and costly cycle. "Hey, These Guys Suck!" I love my Apple iPad because it's so easy to use. The explosion of these types of technologies, combined with new media channels, has raised our expectations and made us hyperaware of what's going on and what's available. In addition, social media has given us a megaphone to share experiences both positive and negative with greater impact. We are now an always-on culture that thrives on our ability to access, connect, and share anywhere anytime. If we don't get the service, product, or value we expect, it is easy to tell many people about it. We also can quickly learn where else to get what we want. Consumers have the power of influence and choice at a global scale. The businesses that understand this principle are able to leverage that power to their advantage. The ones that don't, suffer from it. Which camp are you in?Note: This is Part 1 in a three-part series. Stop back for Part 2 on November 19.

  • What do you need to know to be a world-class master software developer? [closed]

    - by glitch
    I wanted to bring up this question to you folks and see what you think, hopefully advise me on the matter: let's say you had 30 years of learning and practicing software development in front of you, how would you dedicate your time so that you'd get the biggest bang for your buck. What would you both learn and work on to be a world-class software developer that would make a large impact on the industry and leave behind a legacy? I think that most great developers end up being both broad generalists and specialists in one-two areas of interest. I'm thinking Bill Joy, John Carmack, Linus Torvalds, K&R and so on. I'm thinking that perhaps one approach would be to break things down by categories and establish a base minimum of "software development" greatness. I'm thinking: Operating Systems: completely internalize the core concepts of OS, perhaps gain a lot of familiarity with an OSS one such as Linux. Anything from memory management to device drivers has to be complete second nature. Programming Languages: this is one of those topics that imho has to be fully grokked even if it might take many years. I don't think there's quite anything like going through the process of developing your own compiler, understanding language design trade-offs and so on. Programming Language Pragmatics is one of my favorite books actually, I think you want to have that internalized back to back, and that's just the start. You could go significantly deeper, but I think it's time well spent, because it's such a crucial building block. As a subset of that, you want to really understand the different programming paradigms out there. Imperative, declarative, logic, functional and so on. Anything from assembly to LISP should be at the very least comfortable to write in. Contexts: I believe one should have experience working in different contexts to truly be able to appreciate the trade-offs that are being made every day. Embedded, web development, mobile development, UX development, distributed, cloud computing and so on. Hardware: I'm somewhat conflicted about this one. I think you want some understanding of computer architecture at a low level, but I feel like the concepts that will truly matter will be slightly higher level, such as CPU caching / memory hierarchy, ILP, and so on. Networking: we live in a completely network-dependent era. Having a good understanding of the OSI model, knowing how the Web works, how HTTP works and so on is pretty much a pre-requisite these days. Distributed systems: once again, everything's distributed these days, it's getting progressively harder to ignore this reality. Slightly related, perhaps add solid understanding of how browsers work to that, since the world seems to be moving so much to interfacing with everything through a browser. Tools: Have a really broad toolset that you're familiar with, one that continuously expands throughout the years. Communication: I think being a great writer, effective communicator and a phenomenal team player is pretty much a prerequisite for a lot of a software developer's greatness. It can't be overstated. Software engineering: understanding the process of building software, team dynamics, the requirements of the business-side, all the pitfalls. You want to deeply understand where what you're writing fits from the market perspective. The better you understand all of this, the more of your work will actually see the daylight. This is really just a starting list, I'm confident that there's a ton of other material that you need to master. As I mentioned, you most likely end up specializing in a bunch of these areas as you go along, but I was trying to come up with a baseline. Any thoughts, suggestions and words of wisdom from the grizzled veterans out there who would like to share their thoughts and experiences with this? I'd really love to know what you think!

  • I need help with 2D collision response (of stacking rotating polygons, with friction and gravity, for a game)

    - by Register Sole
    Hi I am looking for suggestions on how to write a collision response for game programming purpose (so not a scientific simulation). I am dealing with 2D polygons that are rotating, and I want them to be able to stack. I also want friction and gravity. I have a detection mechanism that returns the separating axis, how long the polygons are overlapping, and up to 2 points of contact. For the response, I am currently using an impulse-based response, which main idea is: find the separating axis, length of overlap, and the point of contact (if there are two, pick a random point between to simulate averaged force. i believe there are better ways than this) separate the object (modifying their positions, taking into account of their masses. i do not separate them completely though, to keep track that they are colliding to reduce jitter) calculate normal force based on the coefficient of restitution as if there is no friction. calculate friction, as if there is no normal force. I also assume that the direction of the friction is the same throughout the collision. apply the two forces (which result in a rather inaccurate result, since each force is calculated as if the other is not present. for non-rotating bodies though, this method is exact) I am aware that this method requires the coefficient of friction to be sufficiently small due to the assumption that the direction of friction stays the same in a collision. Also, the result is visually satisfying if gravity is not present. However, when there is gravity, objects on ground jitter and drift (even with zero coefficient of restitution)! It also happens for stacking objects. Larger coefficient of restitution and gravity increase the jittering. I hope you can help me with this. Some things i would like to know more about is how to handle collision with two point of contacts (how to end up having an object sitting still on the ground?), how to reduce, and prevent if possible, jitter and drift (do people use the most accurate method possible, or is there a trick to overcome this?), and how to handle multiple objects collision (for example, in the case of stacking objects, how do I check collisions between all of them and keep them all stable at every frame so they don't jitter?). A total reformulation of my algorithm is also welcomed, as long as it works. Another thing to note is that I am not making a Physics game, so I only need a visually satisfying response (though a realistic response is preferable, if it is not performance-heavy). But surely jittering and drifting objects on flat ground are not at all acceptable. In addition, I am a Physics student, so feel free to talk about impulse and whatever needed. Finally, I'm sorry for the long post. I tried to be as concise as I can. Thank you for reading it! EDIT It seems what I didn't manage to come up all this time is to separate resting contact as a class of its own and how to solve them. Currently reading the paper suggested by Jedediah. More suggestions on the topic are welcome :) CASE CLOSED After reading various papers referenced in the paper, successfully implemented simultaneous impulse method (referring to the original paper by Erin Catto, [Catt05]). Thanks maaaan!! The paper is wonderful. The current system is visibly much better than the previous. Still haven't separated resting contact as a class of its own though, which brings me to my next question. Love you all! Haha (sorry, I'm just so happy thanks to you).

  • I am not satisfied with my career and accomplished nothing in my life. what should I do now [on hold]

    - by user2906155
    After my complete my College education I got chance to work on software programming. I work on few software and now nothing make me feel good. I don't like web-programming. Can't have too much mind to play with other people in team a designer or a senior. it's totally time wasting for me. We do integration without any source code control. copy through pen drive. I write in too many language for web-programming but know nothing about any language specially. I don't like to have a BOSS. I would like to do something on my own. From last 3 year I thing I will got a better job but I am unable to get it. I am not good at Programming nor my English is native. I have a big list for pay then my salary. I have problem with nothing. my atmosphere is about illiterate people. they abuse 24 hours a day. this thing make me sick. people watch CRIME patrol my home (watching rape in TV because it's happen to someone). I do my work from home. I don't like to live in my state. All state is one of the biggest illiterate state of my country. Once I apply for a Job in China and it's look like I can get thing Job but I don't get it. My family doesn't want me to settle anywhere else. I told my family 4 time a day that I can't live in this worst situation. Everyone (including the person who I work for) tell me that you can do it only you have money. Now I really don't know how to make money. My job not allow me to work for anyone. My productivity going down since I don't learn anything new. I thing if this happen to me for next 2 year I don't have any knowledge more then a peon. I hate it. When I was in other city then I see that if I spent 7 days their all my 7 days going better. even I go for travelling in green places then I like it. but all I hate it where I work for. When I work on other city then I see my productivity are improved and I don't hate my work. I listen a song "If you don't your love what are you doing it for". I seriously don' t know what I still live here because this place gave me nothing but depression and trouble. for people I clear that I don't belong to RICH or middle class family. All I got is doing something on my own or help of someone. affording a rental place make my run on footpath. All I save in one month is just 10$ (approximately) (actually I afford some guys's education now). Can a programmer live worst life like this. I really not happy. Today is a festival in India and I don't celebrate it because I really hate myself. I want to do suicide. someone guide me how to start solving this headache

  • Why is 0 false?

    - by Morwenn
    This question may sound dumb, but why does 0 evaluates to false and any other [integer] value to true is most of programming languages? String comparison Since the question seems a little bit too simple, I will explain myself a little bit more: first of all, it may seem evident to any programmer, but why wouldn't there be a programming language - there may actually be, but not any I used - where 0 evaluates to true and all the other [integer] values to false? That one remark may seem random, but I have a few examples where it may have been a good idea. First of all, let's take the example of strings three-way comparison, I will take C's strcmp as example: any programmer trying C as his first language may be tempted to write the following code: if (strcmp(str1, str2)) { // Do something... } Since strcmp returns 0 which evaluates to false when the strings are equal, what the beginning programmer tried to do fails miserably and he generally does not understand why at first. Had 0 evaluated to true instead, this function could have been used in its most simple expression - the one above - when comparing for equality, and the proper checks for -1 and 1 would have been done only when needed. We would have considered the return type as bool (in our minds I mean) most of the time. Moreover, let's introduce a new type, sign, that just takes values -1, 0 and 1. That can be pretty handy. Imagine there is a spaceship operator in C++ and we want it for std::string (well, there already is the compare function, but spaceship operator is more fun). The declaration would currently be the following one: sign operator<=>(const std::string& lhs, const std::string& rhs); Had 0 been evaluated to true, the spaceship operator wouldn't even exist, and we could have declared operator== that way: sign operator==(const std::string& lhs, const std::string& rhs); This operator== would have handled three-way comparison at once, and could still be used to perform the following check while still being able to check which string is lexicographically superior to the other when needed: if (str1 == str2) { // Do something... } Old errors handling We now have exceptions, so this part only applies to the old languages where no such thing exist (C for example). If we look at C's standard library (and POSIX one too), we can see for sure that maaaaany functions return 0 when successful and any integer otherwise. I have sadly seen some people do this kind of things: #define TRUE 0 // ... if (some_function() == TRUE) { // Here, TRUE would mean success... // Do something } If we think about how we think in programming, we often have the following reasoning pattern: Do something Did it work? Yes -> That's ok, one case to handle No -> Why? Many cases to handle If we think about it again, it would have made sense to put the only neutral value, 0, to yes (and that's how C's functions work), while all the other values can be there to solve the many cases of the no. However, in all the programming languages I know (except maybe some experimental esotheric languages), that yes evaluates to false in an if condition, while all the no cases evaluate to true. There are many situations when "it works" represents one case while "it does not work" represents many probable causes. If we think about it that way, having 0 evaluate to true and the rest to false would have made much more sense. Conclusion My conclusion is essentially my original question: why did we design languages where 0 is false and the other values are true, taking in account my few examples above and maybe some more I did not think of? Follow-up: It's nice to see there are many answers with many ideas and as many possible reasons for it to be like that. I love how passionate you seem to be about it. I originaly asked this question out of boredom, but since you seem so passionate, I decided to go a little further and ask about the rationale behind the Boolean choice for 0 and 1 on Math.SE :)

  • MVVM/Presentation Model With WinForms

    - by Erik Ashepa
    Hi, I'm currently working on a brownfield application, it's written with winforms, as a preparation to use WPF in a later version, out team plans to at least use the MVVM/Presentation model, and bind it against winforms... I've explored the subject, including the posts in this site (which i love very much), when boiled down, the main advantage of wpf are : binding controls to properties in xaml. binding commands to command objects in the viewmodel. the first feature is easy to implement (in code), or with a generic control binder, which binds all the controls in the form. the second feature is a little harder to implement, but if you inherit from all your controls and add a command property (which is triggered by an internal event such as click), which is binded to a command instance in the ViewModel. The challenges I'm currently aware of are : implementing a commandmanager, (which will trigger the CanInvoke method of the commands as necessery. winforms only supports one level of databinding : datasource, datamember, wpf is much more flexible. am i missing any other major features that winforms lacks in comparison with wpf, when attempting to implement this design pattern? i sure many of you will recommend some sort of MVP pattern, but MVVM/Presentation model is the way to go for me, because I'll want future WPF support. Thanks in advance, Erik.

  • WPF: TreeViewItem bound to an ICommand

    - by Richard
    Hi All, I am busy creating my first MVVM application in WPF. Basically the problem I am having is that I have a TreeView (System.Windows.Controls.TreeView) which I have placed on my WPF Window, I have decide that I will bind to a ReadOnlyCollection of CommandViewModel items, and these items consist of a DisplayString, Tag and a RelayCommand. Now in the XAML, I have my TreeView and I have successfully bound my ReadOnlyCollection to this. I can view this and everything looks fine in the UI. The issue now is that I need to bind the RelayCommand to the Command of the TreeViewItem, however from what I can see the TreeViewItem doesn't have a Command. Does this force me to do it in the IsSelected property or even in the Code behind TreeView_SelectedItemChanged method or is there a way to do this magically in WPF? This is the code I have: <TreeView BorderBrush="{x:Null}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <TreeView.Items> <TreeViewItem Header="New Commands" ItemsSource="{Binding Commands}" DisplayMemberPath="DisplayName" IsExpanded="True"> </TreeViewItem> </TreeView.Items> and ideally I would love to just go: <TreeView BorderBrush="{x:Null}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <TreeView.Items> <TreeViewItem Header="New Trade" ItemsSource="{Binding Commands}" DisplayMemberPath="DisplayName" IsExpanded="True" Command="{Binding Path=Command}"> </TreeViewItem> </TreeView.Items> Does someone have a solution that allows me to use the RelayCommand infrastructure I have. Thanks guys, much appreciated! Richard

  • DRY Validation with MVC2

    - by Matthew
    Hi All, I'm trying to figure out how I can define validation rules for my domain objects in one single location within my application but have run in to a snag... Some background: My location has several parts: - Database - DAL - Business Logic Layer - SOAP API Layer - MVC website The MVC website accesses the database via the SOAP API, just as third parties would. We are using server and and client side validation on the MVC website as well as in the SOAP API Layer. To avoid having to manually write client side validation we are implementing strongly typed views in conjunction with the Html.TextBoxFor and Html.ValidationMessageFor HTML helpers, as shown in Step 3 here. We also create custom models for each form where one form takes input for multiple domain objects. This is where the problem begins, the HTML helpers read from the model for the data annotation validation attributes. In most cases our forms deal with multiple domain objects and you can't specify more than one type in the <%@Page ... Inherits="System.Web.Mvc.ViewPage" % page directive. So we are forced to create a custom model class, which would mean duplicating validation attributes from the domain objects on to the model class. I've spent quite some time looking for workarounds to this, such has referencing the same MetadataType from both the domain class and the custom MVC models, but that won't work for several reasons: You can only specify one MetadataType attribute per class, so its a problem if a model references multiple domain objects, each with their own metadata type. The data annotation validation code throws an exception if the model class doesn't contain a property that is specified in the referenced MetadataType which is a problem with the model only deals with a subset of the properties for a given domain object. I've looked at other solutions as well but to no avail. If anyone has any ideas on how to achieve a single source for validation logic that would work across MVC client and server side validation functionality and other locations (such as my SOAP API) I would love to hear it! Thanks in advance, Matthew

  • Reducing WPF binding boilerplate with styles - updating the bindings themselves via styling?

    - by Eamon Nerbonne
    I'm still learning the WPF ropes, so if the following question is trivial or my approach wrong-headed, please do speak up... I'm trying to reduce boilerplate and it sounds like styles are a common way to do so. In particular: I've got a bunch of fairly mundane data-entry fields. The controls for these fields have various properties I'd like to set based on the target of the binding - pretty normal stuff. However, I'd also like to set properties of the binding itself in the style to avoid repetitiveness. For example: <TextBox Style="{StaticResource myStyle}"> <TextBox.Text> <Binding Path="..." Source="..." ValidatesOnDataErrors="True" ValidatesOnExceptions="True" UpdateSourceTrigger="PropertyChanged"> </Binding> </TextBox.Text> </TextBox> Now, is there any way to use styling - or some other technique to write the previous example somewhat like this: <TextBox Style="{StaticResource myStyle}" Text="{Binding Source=... Path=...}/> That is, is there any way to set all bindings that match a particular selection (here, on controls with the myStyle style) to validate data and to use a particular update trigger? Is it possible to template or style bindings themselves? Clearly, the second syntax is much, much shorter and more readable, and I'd love to be able to get rid of other similar boilerplate to keep my UI code comprehensible to myself :-).

  • Applying Test Driven Development to a tightly coupled architecture

    - by Chris D
    Hi all, I've recently been studying TDD, attended a conference and have dabbled in few tests and already I'm 100% sold, I absolutely love it TDD. As a result I've raised this with my seniors and they are prepared to give it a chance, so they have tasked me with coming up with a way to implement TDD in the development of our enterprise product. The problem is our system has evolved since the days of VB6 to .NET and implements alot of legacy technology and some far from best practice development techniques i.e. alot of business logic in the ASP.NET code behind and client script. The largest problem however is how our classes are tightly coupled with database access; properties, methods, constructors - usually has some database access in some form or another. We use an in-house data access code generator tool that creates sqlDataAdapters that gives us all the database access we could ever want, which helps us develop extremely quickly, however, classes in our business layer are very tightly coupled to this data layer - we aren't even close to implementing some form of repository design. This and the issues above have created me all sorts of problems. I have tried to develop some unit tests for some existing classes I've already written but the tests take ALOT longer to run since db access is required, not to mention since we use the MS Enterprise Caching framework I am forced to fake a httpcontext for my tests to run successfully which isn't practical. Also, I can't see how to use TDD to drive the design of any new classes I write since they have to be soo tightly coupled to the database ... help! Because of the architecture of the system it appears I can't implement TDD without some real hack which in my eyes just defeats the aim of TDD and the huge benefits that come with. Does anyone have any suggestions how I could implement TDD with the constraints I'm bound too? or do I need to push the repository design pattern down my seniors throats and tell them we either change our architecture/development methodology or forget about TDD altogether? :) Thanks

  • C# web cam WM_CAP_CONNECT: Want to force a capture source when multiple capture sources present.

    - by Codejoy
    I am using WebCam_Capture code I found online to access through C# a web cam. On a computer with one video source it works like a charm! (Program starts up at start up, finds the webcam and it works). Though on a computer with many video sources (Say a web cam and then manycam running on top of that), the program starts and queries the user which source to use. I would love my program to start up autonomously at the restart of a machine so this waiting for user input throws a wrench in that, anyway I can force it to just select say the first found source and go with that? So i have some webcam code I yes indeed found online here: http://channel9.msdn.com/forums/TechOff/93476-Programatically-Using-A-Webcam-In-C/?CommentID=94149 and now in preparing this post I did do more research and found out that my issue lies in this line from the above code: SendMessage(mCapHwnd, WM_CAP_CONNECT, 0, 0); That is what connects the webcam up, the only issue is that the above brings up this annoying video source dialog if I have more than one source. I want it to just use the first source so that dialog doesn't come up. I tried passing in different values where the 0's are, sure enough the dialog doesn't come up but it doesn't work either. Anyone know if there is a value I can pass to the SendMessage to suspend the dialog and yet have it select the first video source it finds?

  • How do I make an ellipse blink?

    - by MedicineMan
    I am trying to make a custom control in WPF. I want it to simulate the behavior of a LED that can blink. There are three states to the control: On, Off, and Blinking. I know how to set On and Off through the code behind, but this WPF animation stuff is just driving me nuts!!!! I cannot get anything to animate whatsoever. The plan is to have a property called state. When the user sets the value to blinking, I want the control to alternate between green and grey. I'm assuming I need a dependency property here, but have no idea. I had more xaml before but just erased it all. it doesn't seem to do anything. I'd love to do this in the most best practice way possible, but at this point, I'll take anything. I'm half way to writing a thread that changes the color manually at this point. <UserControl x:Class="WpfAnimation.LED" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <Grid> <Ellipse x:Name="MyLight" Height="Auto" Width="Auto"/> </Grid> </UserControl>

  • GIT repository layout for server with multiple projects

    - by Paul Alexander
    One of the things I like about the way I have Subversion set up is that I can have a single main repository with multiple projects. When I want to work on a project I can check out just that project. Like this \main \ProductA \ProductB \Shared then svn checkout http://.../main/ProductA As a new user to git I want to explore a bit of best practice in the field before committing to a specific workflow. From what I've read so far, git stores everything in a single .git folder at the root of the project tree. So I could do one of two things. Set up a separate project for each Product. Set up a single massive project and store products in sub folders. There are dependencies between the products, so the single massive project seems appropriate. We'll be using a server where all the developers can share their code. I've already got this working over SSH & HTTP and that part I love. However, the repositories in SVN are already many GB in size so dragging around the entire repository on each machine seems like a bad idea - especially since we're billed for excessive network bandwidth. I'd imagine that the Linux kernel project repositories are equally large so there must be a proper way of handling this with Git but I just haven't figured it out yet. Are there any guidelines or best practices for working with very large multi-project repositories?

  • How to populate Java (web) application with initial data using Spring/JPA/Hibernate

    - by Tuukka Mustonen
    I want to setup my database with initial data programmatically. I want to populate my database for development runs, not for testing runs (it's easy). The product is built on top of Spring and JPA/Hibernate. Developer checks out the project Developer runs command/script to setup database with initial data Developer starts application (server) and begins developing/testing then: Developer runs command/script to flush the database and set it up with new initial data because database structures or the initial data bundle were changed What I want is to setup my environment by required parts in order to call my DAOs and insert new objects into database. I do not want to create initial data sets in raw SQL, XML, take dumps of database or whatever. I want to programmatically create objects and persist them in database as I would in normal application logic. One way to accomplish this would be to start up my application normally and run a special servlet that does the initialization. But is that really the way to go? I would love to execute the initial data setup as Maven task and I don't know how to do that if I take the servlet approach. There is somewhat similar question. I took a quick glance at the suggested DBUnit and Unitils. But they seem to be heavily focused in setting up testing environments, which is not what I want here. DBUnit does initial data population, but only using xml/csv fixtures, which is not what I'm after here. Then, Maven has SQL plugin, but I don't want to handle raw SQL. Maven also has Hibernate plugin, but it seems to help only in Hibernate configuration and table schema creation (not in populating db with data). How to do this?

  • Notification Email Best Practices--From Server Setup to Programming

    - by Andrew Wagner
    All, I'm in the process now of building a SaaS tool that allows network admins to generate notification emails to the members of the end-users of our platform (among many many other things). I'm running into a bit of an "out of my expertise" wall, as I know there are a lot of variables involved with configuring an application that can: Run in a distributed way via load balancing and still-- Leverage a single mail server for sending notification emails Process unsubscribe requests Avoid any ISP blacklisting in the process. If anyone has the time and has done this before, I'd love if you could walk me through the A-Z of best practices both from a configuration perspective and an execution perspective for generating these emails (anything from necessary DNS settings to ideal SMTP setup and configuration) Currently, our application generates email via Google Apps using the PHPMailer class. While this works well, it doesn't queue messages (potential for timeout problems if any of our clients amass a very large list of end-users), and Google limits the amount of allowed generated email messages to 500/day. I know this is a lofty question, but any guidance you could provide would be smashing and a big help as we work through this hurtle in our beta development stage. Thanks!

  • Using the Rijndael Object in VB.NET

    - by broke
    I'm trying out the Rijndael to generate an encrypted license string to use for our new software, so we know that our customers are using the same amount of apps that they paid for. I'm doing two things: Getting the users computer name. Adding a random number between 100 and 1000000000 I then combine the two, and use that as the license number(This probably will change in the final version, but I'm just doing something simple for demonstration purposes). Here is some sample codez: Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim generator As New Random Dim randomValue As Integer randomValue = generator.Next(100, 1000000000) ' Create a new Rijndael object to generate a key ' and initialization vector (IV). Dim RijndaelAlg As Rijndael = Rijndael.Create ' Create a string to encrypt. Dim sData As String = My.Computer.Name.ToString + randomValue.ToString Dim FileName As String = "C:\key.txt" ' Encrypt text to a file using the file name, key, and IV. EncryptTextToFile(sData, FileName, RijndaelAlg.Key, RijndaelAlg.IV) ' Decrypt the text from a file using the file name, key, and IV. Dim Final As String = DecryptTextFromFile(FileName, RijndaelAlg.Key, RijndaelAlg.IV) txtDecrypted.Text = Final End Sub That's my load event, but here is where the magic happens: Sub EncryptTextToFile(ByVal Data As String, ByVal FileName As String, ByVal Key() As Byte, ByVal IV() As Byte) Dim fStream As FileStream = File.Open(FileName, FileMode.OpenOrCreate) Dim RijndaelAlg As Rijndael = Rijndael.Create Dim cStream As New CryptoStream(fStream, _ RijndaelAlg.CreateEncryptor(Key, IV), _ CryptoStreamMode.Write) Dim sWriter As New StreamWriter(cStream) sWriter.WriteLine(Data) sWriter.Close() cStream.Close() fStream.Close() End Sub There is a couple things I don't understand. What if someone reads the text file and recognizes that it is Rijndael, and writes a VB or C# app that decrypts it? I don't really understand all of this code, so if you guys can help me out I will love you all forever. Thanks in advance
