  • Korea&rsquo;s Anti Abortion / Pro Life Movement

    - by Randy Walker
    The South Korean government is in dire straits.  The national birth rate continues to decline and as the population grows older, there aren’t enough children being born to support the country long term.  The social issues of post Korean War are coming back to haunt the empowered nation.  Being torn apart by the Korean War (nicknamed the forgotten war in America) and with a nation facing starvation, South Korea allowed hundreds of thousands of their children to be adopted abroad.  This has created a problem of epidemic proportions, essentially devaluing life in Korea and child rearing. In an effort to encourage birth rates, the government encouraged their workers to go home early and procreate by turning off the lights in buildings.  Something unknown to me, was the illegalization of abortion except in special cases. According to the this article, http://joongangdaily.joins.com it’s working.  Abortions are down and women are being encouraged to give birth.  However the flip side is illegal risky abortions are on the rise, with potential back alley abortions looming.  But with a nation facing it’s potential implosion, it has to continue it’s efforts to encourage mothers to give birth. Many of the issues that America has faced is in stark contrast to South Korea.  Abortion has been a generally accepted procedure for some time.  If you’ll recall, I mentioned South Korea devalued their children.  But the nation’s problems lie so much deeper.  Being an Asian nation, saving “face” is an important aspect of life.  And being an unwed mother disgraces the family.  Living as a single mother in South Korea is a difficult life.  Most married mothers stay at home to take care of the children.  Being a shunned single mother that has a hard time getting a job (because you are a single mother) and affording child care isn’t like life in America. If we in the states suddenly faced a birthrate crisis, what would the U.S. government do?

  • What's wrong performing unit test against concrete implementation if your frameworks are not going to change?

    - by palm snow
    First a bit of background: We are re-architecting our product suite that was written 10 years ago and served its purpose. One thing that we cannot change is the database schema as we have 500+ client base using this system. Our db schema has over 150+ tables. We have decided on using Entity Framework 4.1 as DAL and still evaluating various frameworks for storing our business logic. I am investigation to bring unit testing into the mix but I also confused as to how far I need to go with setting up a full blown TDD environment. One aspect of setting up unit testing is by getting into implementing Repository, unit of work and mocking frameworks etc. This mean there will be cost and investment on the code-bloat associated with all these frameworks. I understand some of this could be auto-generated but when it comes to things like behaviors, that will be mostly hand written. Just to be clear, I am not questioning the important of unit testing your code. I am just not sure we need all its components (like repository, mocking etc.) when we are fairly certain of storage mechanism/framework (SQL Server/Entity Framework). All that code bloat with generic repositories make sense when you need a generic layers with ability to change this whenever you like however its very likely a YAGNI in our case. What we need is more of integration testing where we can unit-test our code with concrete repository objects and test data in database. In this scenario, just running integration test seem to be more beneficial in our case. Any thoughts if I am missing any thing here?

  • Which powerful laptop, with UK keyboard and 8gb ram

    - by RobinL
    I've been searching high and low for high spec laptops compatible with Ubuntu. The lack of coherent information on the topic is high (considering the number of people who apparently want a good laptop with an OS operating system). So I thought you may have some advice. My requirements: a) has = 8Gb ram b) is compatible with Ubuntu c) has a UK keyboard and charger d) does not cost the Earth Which would you go for? Does anyone have good experience with high-end laptops running Ubuntu? So here's some background research: Samsung Series 7 looks great, but has various problems on Ubuntu, including: poor battery life, touchpad does not work, graphics card not fully supported and sucks power when it does (see [here] and [here], for example). Other options on the [wish list] include: the sensible [Acer] (possibly n.1 choice, but not sure about graphics card compatibility or battery), a nice looking [HP Pavilion dv6-6c56ea], which also has incompatibility issues (see [here] and [here] and check ubuntuforums) And another [Acer] which may be best due to its simplicity and cheapness. Other sub-questions: didn't Dell offer Ubuntu support for decent laptops (above 6Gb ram their offerings are scarce); what about pre-installed options such as those provided by System76? If it weren't for the UK keyboard and charger, I'd probably go for this [amazing-looking] [machine]. Many thanks for any advice, P.s. Apologies for lack of hyperlinks; I'm a noob so only allowed 2 :( All 10 links are available here though for the interested reader :) Robin

  • How do I create the "Gnome-Desktop-Item-Edit" program's launch icon with root privileges and more?

    - by GanZ
    I personally dont prefer running commands in terminal to achieve a task and prefer apps to execute the job. Creating launcher for apps is one such command where I prefer the gnome-desktop-item-edit application for creating launchers. If the gnome package is installed, just searching "create launcher" opens the app. But, it doesnt serve any purpose, because for starters the application cannot create launchers for various apps without root permission and the location where the apps have to be created. Usually the launcher apps with root permission can be created at /usr/share/applications and without root permission at /.local/share/applications. I dont prefer the latter location as it is vulnerable to deletion. Hence, in order to create the launchers through gnome with root, everytime I am forced to open this through terminal using the below command! $ sudo gnome-desktop-item-edit ~/.local/share/applications --create-new I dont want to open terminal everytime I want to create an application launcher on unity! I am able to lock the "Create Launcher" App in the Launcher, but not with root privileges So I want to be able to create the "Create Launcher" app shortcut on unity with default root privileges and for the app to create the launchers at usr/share/applications by default! Please help! P.S. I dont have enough rep points to add screenshots to help with the question!

  • Game Asset Management

    - by user964123
    I am making my first small mobile game in C# XNA. Lets say I have 3 screens, the main menu, options and game screen. A single game session usually lasts for 1 min, so the user will alternate frequently between the main menu and game screen. Therefore, once I load the textures for either screen, I want to keep them in memory to avoid frequent reloading. Both screens share some assets like their background textures, but differ in others. The first solution I came up with is making 2 texture factory classes, MainScreenAssetFactory and GameScreenAssetFactory, each with their own content manager, and ill store them in a globally accessible point so that they persist after either screen is destroyed. There is also a OptionsScreenAssetFactory, but that I dont want to cache it since the options screen is rarely visited. A typical Factory would look something like this public class MainScreenAssetFactory { private readonly ContentManager contentManager; public MainScreenAssetFactory(IServiceProvider serviceProvider, string rootDirectory) { contentManager = new ContentManager(serviceProvider) { RootDirectory = rootDirectory }; } public Texture2D ListElementBackground { get { return return contentManager.Load<Texture2D>("UserTab"); } } public Texture2D ListElementBulletPoint { get { return return contentManager.Load<Texture2D>("TabIcon"); } } public Texture2D LoggedOutUser { get { return return contentManager.Load<Texture2D>("LoggedOutUser"); } } } Since both Main, Options and Game Screen share some common resources, instead of loading them more than once, I created another class CommonAssetTexFactory which holds the common stuff and stays in-memory during the app lifetime. For example, this class gets passed to the options screen when it is created. However, given my small game with its few assets, I am already finding this solution cumbersome and inflexible. Changing anything would require looking to see if its already in the common factory, and if not, modifying existing factories and so on. And this is just considering textures currently, i didnt add sound files yet. I cant imagine bigger games with thousands of resources using this approach. A better idea must exist. Would someone please enlighten me?

  • share code between check and process methods

    - by undu
    My job is to refactor an old library for GIS vector data processing. The main class encapsulates a collection of building outlines, and offers different methods for checking data consistency. Those checking functions have an optional parameter that allows to perform some process. For instance: std::vector<Point> checkIntersections(int process_mode = 0); This method tests if some building outlines are intersecting, and return the intersection points. But if you pass a non null argument, the method will modify the outlines to remove the intersection. I think it's pretty bad (at call site, a reader not familiar with the code base will assume that a method called checkSomething only performs a check and doesn't modifiy data) and I want to change this. I also want to avoid code duplication as check and process methods are mostly similar. So I was thinking to something like this: // a private worker std::vector<Point> workerIntersections(int process_mode = 0) { // it's the equivalent of the current checkIntersections, it may perform // a process depending on process_mode } // public interfaces for check and process std::vector<Point> checkIntersections() /* const */ { workerIntersections(0); } std::vector<Point> processIntersections(int process_mode /*I have different process modes*/) { workerIntersections(process_mode); } But that forces me to break const correctness as workerIntersections is a non-const method. How can I separate check and process, avoiding code duplication and keeping const-correctness?

  • Working Qt controls in a 3d environment

    - by Jay
    I need some advice from a Qt expert. The background: I have a 3D engine (ogre3d) working in concert with Qt. The 3D Content is displayed in a widget (using a custom OS window in the client area). I'm able to overlay arbitrary Qt widgets onto the 3d world using the widget render() method and a shared bitmap. This makes a great "heads up display". I can use the standard Qt style sheets and animation using this technique. My goal I'd like to go a step further and allow the user to move these rendered widgets using the mouse. I'd like some advice on the best way to implement this. Possible solutions: The widgets in the HUD are not part of the inheritance chain. I render them manually. They don't get events though. I could add them to the inheritance chain so they get events in the usual way. Then I would need to change them to render to my shared bitmap instead of to the operating system. I looked at this once but couldn't find enough information to implement it. Capture mouse events in the 3D display widget and EMIT them to child controls. I basically create my own event handling chain. Any suggestions on how to implement this? I'm also considering switching to Qt5. I'm not sure how that might affect this decision.

  • How do you keep down your urge to learn many things [closed]

    - by devsundar
    One of the difficulties i have is to lower my urge to learn new things (Languages, tools, frameworks etc.). I know it's good to stay the bleeding edge, but at the same time i want to learn things properly. I really see that i need to strike a balance between staying bleeding edge and knowing things properly. For example: Before choosing Arch (Desktop), Ubuntu(Server) and Knoppix(Portable) -- depending on situation -- as favourite distributions. Virtually i have tried all popular linux distributions. You name any popular linux (Redhat, Ubuntu, Arch, Suse, Knoppix, Slax, Slackware) i have tried it for some time. In fact i have spent few years experimenting the operating systems. Before choosing Python, Javascript (nodejs). I have tried all the languages i cameacross Scala, Haskell, Erlang, Ruby, Python, Perl, Scheme. Same applies for database. All popular db RDBMS (Oracle, Mysql, Postgres, SQLite[Favourite] etc) and NoSQL (Mongo, Couch, Neo4j etc.). Advantages i see: We get a overall picture of the technologies/tools/languages. It's useful to select the right tool for the job. We develop a taste and choose the One we like. Disadvantages: I feel that i spend somuch time and see a need to strike a balance. In summary, for e.g. If i see a blog post in HackerNews about CofeeScript i will try it out irrespective of what i am currently learning (Say Haskell). I switch back to learning Haskell, then again i see DART i check it out. And this continues.. Effectively i take more time to learn Haskell, but learnt about other new stuff on the way. The quetion i have is how do you strike a balance between staying bleeding edge and learning properly.

  • Do you feel bad when you have to learn new things?

    - by tactoth
    New thing is not always cool. I see many people say they are very bored by doing the similar things day after day. For me it's the opposite - I'm always learning something new. During the last one and a harf year, nearly every two months I need to do lots of researches on a totally new topic: RTMP, MP4, SIP, VNC, Smooth streaming, ..., I have to read lots of specifications, download tones of open source projects to understand concepts, and turn them into my runnable code. And it was so bad! My brain has never been very sure and very familiar with anything, and when it's close to be sure and familiar, it'll have to switch to next thing. I kind of envy people who build upper level applications because they can be very focusing, and their knowledge set includes most things their job requires. Everything is quite measurable, direct and straightforward. Have you ever had the similar feeling? I'm thinking of asking my boss to assign me some other piece of work so that I work like moving forward on a broad road instead of figuring out a way in the dark, I think it'll be more relaxing, any suggestion?

  • In which fields does quality of the software product matter as much as the completion time?

    - by Nav
    Someone told me that if the software product meets clients expectations, it is good quality. But I've worked with Interaction Designers (the same kind of people who made Gmail's interface and usability so cool!), and I've loved working with them because even though they came up with hundreds of changes in requirements, and emphasised on many many subtle details, when the software was complete, I could look at the product and say WOW! The current place I work, the only thing that matters is completing the project on time. As long as it works and as long as the client says it's ok, nobody bothers to improve it. I'm not talking about gold-plating, but I believe that for a programmer to enjoy his (well, maybe her too ;) ) job, they should be able to proudly say that "Hey, I made that software" and that comes only when the product is of good quality. Apart from your opinions on this, I'd also like to know which fields (Eg. Aerospace, Finance etc.) could I find companies (or you could mention the company name) where the quality of a product is as important as completing the project on time?

  • How "commercially savvy" should software developers be? [closed]

    - by mattnz
    I have been watching answers to many questions on this site, and have come to the conclusion that commercial pragmatism does not factor into many software development discussions. As a result, I seriously wonder at the commercial skills within the industry, specifically the ability to deliver projects on time and to a budget. I see no indication from the site that commercially successful project delivery is a serious concern, yet the industry has a reputation for poor performance in this. Rarely, if ever, does the cost of time factor into discussions. I have never seen concepts such as opportunity cost, time to market, competitive advantage or cash flow mentioned, let alone discussed in technical answers to questions. How can you answer virtually any question without understanding the commercial background on which it is asked? Even Open source projects have a need to operate efficiently and deploy their limited resources to providing the most value for effort. Typically small start-ups have cash flow issues that outweigh longevity concerns, yet they are typically still advised to build for a future they probably won’t have if they do. Is it fair to say that these problems are solely the Managers and Project managers to solve, or are we, as developers, also responsible for ensuring successful on time, within budget delivery of projects, even if those budgets do not allow use to achieve engineering excellence?

  • What guidelines should be followed when implementing third-party tracking pixels?

    - by Strozykowski
    Background I work on a website that gets a fair amount of traffic, and as such, we have implemented different tracking pixels and techniques across the site for various specific reasons. Because there are many agencies who are sending traffic our way through email campaigns, print ads and SEM, we have agreements with a variety of different outside agencies for tracking these page hits. Consequently, we have tracking pixels which span the entire site, as well as some that are on specific pages only. We have worked to reduce the total number of pixels available on any one page, but occasionally the site is rendered close to unusable when one of these third-party tracking pixels fails to load. This is a huge difficulty on parts of the site where Javascript is needed for functionality built into the page, but is unable to initialize until a 404 is returned on the external tracking pixel. (Sometimes up to 30 seconds later) I have spent some time attempting to research how other firms deal with this sort of instability with third-party components, but have come up a bit short. The plan currently is to implement our own stop-gap method to deal with these external outages, but rather than reinventing the wheel, we wanted to find out how this is dealt with on other sites. Question Is there a good set of guidelines that should be followed when implementing third-party tracking pixels? I would love to see some white papers or other written documents about how other people have dealt with this issue.

  • How to move from Programmer to Project Lead

    - by DoctaStooge
    At my job, I'm currently a programmer, but in the next few weeks I'll be taking control my own project. I was wondering if anyone else here has been in the same situation, and if so, what advice you can offer to help me be able to better run my project. Experience in dealing with contractors would be greatly appreciated. A little more info: Project will have 3 people including myself, with extra people coming in when needing testing. The project has been programmed mainly by 2 people I would like to contribute to the programming as I like doing it and think I can add to the program, but am afraid of how the contractors will react. I don't want to create bad feelings which may harm the project. EDIT: Forgot to mention that I'll have to be picking up communications with customers to make sure their needs are met. Any advice on talking to customers cold would be greatly appreciated. EDIT 2: This is not a new project, I'm picking it up around version 6. Sorry that I didn't make it clear before.

  • Is it reasonable to null guard every single dereferenced pointer?

    - by evadeflow
    At a new job, I've been getting flagged in code reviews for code like this: PowerManager::PowerManager(IMsgSender* msgSender) : msgSender_(msgSender) { } void PowerManager::SignalShutdown() { msgSender_->sendMsg("shutdown()"); } I'm told that last method should read: void PowerManager::SignalShutdown() { if (msgSender_) { msgSender_->sendMsg("shutdown()"); } } i.e., I must put a NULL guard around the msgSender_ variable, even though it is a private data member. It's difficult for me to restrain myself from using expletives to describe how I feel about this piece of 'wisdom'. When I ask for an explanation, I get a litany of horror stories about how some junior programmer, some-year, got confused about how a class was supposed to work and accidentally deleted a member he shouldn't have (and set it to NULL afterwards, apparently), and things blew up in the field right after a product release, and we've "learned the hard way, trust us" that it's better to just NULL check everything. To me, this feels like cargo cult programming, plain and simple. A few well-meaning colleagues are earnestly trying to help me 'get it' and see how this will help me write more robust code, but... I can't help feeling like they're the ones who don't get it. Is it reasonable for a coding standard to require that every single pointer dereferenced in a function be checked for NULL first—even private data members? (Note: To give some context, we make a consumer electronics device, not an air traffic control system or some other 'failure-equals-people-die' product.) EDIT: In the above example, the msgSender_ collaborator isn't optional. If it's ever NULL, it indicates a bug. The only reason it is passed into the constructor is so PowerManager can be tested with a mock IMsgSender subclass.

  • How can I better manage far-reaching changes in my code?

    - by neuviemeporte
    In my work (writing scientific software in C++), I often get asked by the people who use the software to get their work done to add some functionality or change the way things are done and organized right now. Most of the time this is just a matter of adding a new class or a function and applying some glue to do the job, but from time to time, a seemingly simple change turns out to have far-reaching consequences that require me to redesign a substantial amount of existing code, which takes a lot of time and effort, and is difficult to evaluate in terms of time required. I don't think it has as much to do with inter-dependence of modules, as with changing requirements (admittedly, on a smaller scale). To provide an example, I was thinking about the recently-added multi-user functionality in Android. I don't know whether they planned to introduce it from the very beginning, but assuming they didn't, it seems hard to predict all the areas that will be affected by the change (apps preferences, themes, need to store account info somehow, etc...?), even though the concept seems simple enough, and the code is well-organized. How do you deal with such situations? Do you just jump in to code and then sort out the cruft later like I do? Or do you do a detailed analysis beforehand of what will be affected, what needs to be updated and how, and what has to be rewritten? If so, what tools (if any) and approaches do you use?

  • Coping with build order requirements in automated builds

    - by Derecho
    I have three Scala packages being built as separate sbt projects in separate repos with a dependency graph like this: M---->D ^ ^ | | +--+--+ ^ | S S is a service. M is a set of message classes shared between S and another service. D is a DAL used by S and the other service, and some of its model appears in the shared messages. If I make a breaking change to all three, and push them up to my Git repo, a build of S will be kicked off in Jenkins. The build will only be successful if, when S is pushed, M and D have already been pushed. Otherwise, Jenkins will find it doesn't have the right dependent package versions available. Even pushing them simultaneously wouldn't be enough -- the dependencies would have to be built and published before the dependent job was even started. Making the jobs dependent in Jenkins isn't enough, because that would just cause the previous version to be built, resulting in an artifact that doesn't have the needed version. Is there a way to set things up so that I don't have to remember to push things in the right order? The only way I can see it working is if there was a way that a build could go into a pending state if its dependencies weren't available yet. I feel like there's a simple solution I'm missing. Surely people deal with this a lot?

  • Which jar has JBox2d's p5 package

    - by Brantley Blanchard
    Using eclipse, I'm trying to write a simple hello world program in processing that simply draws a rectangle on the screen then has gravity drop it as seen in this Tutorial. The problem is that when I try to import the p5 package, it's not resolving so I can't declare my Physics object. I tried two things. Download the zip, unzip it, then import the 3 jars (library, serialization, & testbed) a. import org.jbox2d.p5.*; doesn't resolve but the others do b. Physics physics; doesn't resolve Download the older standalone testbed jar then import it a. Physics physics; doesn't resolve; Here is basically where I'm starting import org.jbox2d.util.nonconvex.*; import org.jbox2d.dynamics.contacts.*; import org.jbox2d.testbed.*; import org.jbox2d.collision.*; import org.jbox2d.common.*; import org.jbox2d.dynamics.joints.*; import org.jbox2d.p5.*; import org.jbox2d.dynamics.*; import processing.core.PApplet; public class MyFirstJBox2d extends PApplet { Physics physics; public void setup() { size(640,480); frameRate(60); initScene(); } public void draw() { background(0); if (keyPressed) { //Reset everything physics.destroy(); initScene(); } } public void initScene() { physics = new Physics(this, width, height); physics.setDensity(1.0f); physics.createRect(300,200,340,300); } }

  • Storing a pass-by-reference parameter as a pointer - Bad practice?

    - by Karl Nicoll
    I recently came across the following pattern in an API I've been forced to use: class SomeObject { public: // Constructor. SomeObject(bool copy = false); // Set a value. void SetValue(const ComplexType &value); private: bool m_copy; ComplexType *m_pComplexType; ComplexType m_complexType; }; // ------------------------------------------------------------ SomeObject::SomeObject(bool copy) : m_copy(copy) { } // ------------------------------------------------------------ void SomeObject::SetValue(const ComplexType &value) { if (m_copy) m_complexType.assign(value); else m_pComplexType = const_cast<ComplexType *>(&value); } The background behind this pattern is that it is used to hold data prior to it being encoded and sent to a TCP socket. The copy weirdness is designed to make the class SomeObject efficient by only holding a pointer to the object until it needs to be encoded, but also provide the option to copy values if the lifetime of the SomeObject exceeds the lifetime of a ComplexType. However, consider the following: SomeObject SomeFunction() { ComplexType complexTypeInstance(1); // Create an instance of ComplexType. SomeObject encodeHelper; encodeHelper.SetValue(complexTypeInstance); // Okay. return encodeHelper; // Uh oh! complexTypeInstance has been destroyed, and // now encoding will venture into the realm of undefined // behaviour! } I tripped over this because I used the default constructor, and this resulted in messages being encoded as blank (through a fluke of undefined behaviour). It took an absolute age to pinpoint the cause! Anyway, is this a standard pattern for something like this? Are there any advantages to doing it this way vs overloading the SetValue method to accept a pointer that I'm missing? Thanks!

  • Creating dynamic plots

    - by geoff92
    I'm completely new to web programming but I do have a programming background. I'd like to create a site that allows users to visit, enter some specifications into a form, submit the form, and then receive a graph. I have a few questions about this, only because I'm pretty ignorant: Is there a good framework I should start in? I know a lot of java, I'm okay with python, and I learned Ruby in the past. I figure I might use ruby on rails only because I hear of it so often and I think I've also heard it's easy. If anyone has some other recommendation, please suggest. The user will be entering data into a form. I'm guessing the request they'll be making should be one of a GET request, right? Because I don't intend for any of the data they're entering to modify my server (in fact, I don't intend on having a database). The data the user inputs will be used to perform calculations involving lots of matrices. I've written this functionality in python. If I use ruby on rails, should it be instead written in Ruby? Somewhere I've heard that you can either place the load of the work on your server or on the client's computer. Since the code performs heavy math, which option is preferable? How do I alter the setup to either make the client do the work or my server? Should I be using a "cgi-bin"? In the code that I have now, I use matplotlib, a python library, and then "show" the plot in order to see the graph. I specify the x and y limits, but I am able to "drag" the graph in order to see more data within the plot window. Ultimately, I want a graph to be shown on my site with the drag functionality. Is this possible? What if the client drags the graph so far, more computations must be made? Thanks!

  • Book / software to learn ERP?

    - by user22311
    For a while I've been wanting to learn ERP. What I would like to do is set up a system, and then practice running a business doing things like generating invoices, raising purchase orders, producing monthly accounts, keeping track of fixed assets etc. Then look at enhancing the system further by adding custom code. I know there are a variety of open source ERP systems around, but really I would prefer a widely used commercial system as having familiarity with such a system would be more marketable. So are there any such systems that have a free developer version available? I've looked around, but I've had trouble finding such a system. Also I would like to find a good book or more likely books to read on ERP. Ideally I would be able to get an indepth explanation ERP from a business perspective, ie the accounting operations it supports, how to do all the regular accounting tasks, configuration, business operations best practices, accounting controls and so on. In addition I would like an IT perspective, ie setting up the system, developing forms and reports. Unfortunately the few books I've looked at have been really superficial and totally inadequate. They either fall into the beginning programmer camp, where they use the programming tools but concentrate on programming 101 topics like loops, flow control etc. Or they cover setting up the system with lots of screen shots, but little substance as to why things should be done a certain way. I have a programming background but no real experience in implementing ERP systems. Also I have a reasonable accounting knowledge, and have used ERP systems in various jobs, but only to a very limited degree. So are there any ERP experts who can point me in the right direction? Thanks.

  • using apple-mobile-web-app-capable and cache.manifest issue [migrated]

    - by LocoMike
    So I have this simple html file <!DOCTYPE HTML> <html manifest="cache.manifest"><head> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <title>Test</title> <meta http-equiv="content-type" content="text/html"> <meta name="HandheldFriendly" content="true"> <meta name="viewport" content="width=320; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"> <style type="text/css"></style></head> <body marginwidth="0" marginheight="0" topmargin="0" leftmargin="0"> <h1>hello</h1> </body> </html> My cache.manifest is simply CACHE MANIFEST I run this website on my local server (localhost). I load it from iphone safari and it works fine. I then stop the server and load it again, and it works, because the offline cache is doing its job. However... if I save the website as a start icon in the iphone dashboard, and then I try to open it with the server stopped it won't load. However... if I open it with the server running at least once (it will work) then I can open it later without problem. It looks like even though the page was cached in safari, it is not cached in this saved app. Anybody knows how to get around this? Thank you!

  • Can I eventually consider myself a professional developer if I don't have a CS degree? [on hold]

    - by heltonbiker
    Question first, context later: If I am a dedicated, self-taught programmer, always seeking top-quality books AND READING THEM, while successfully applying all that new knowledge into my current work, could I call myself (and offer my work as) a PROFESSIONAL developer? How limiting (or how common) that is nowadays? I am afraid that, no matter how hard I study and practice, it could be too difficult to compete with "actual", college graduated developers, and potential employers might have doubts investing in an "undergraduated" person. Now, context: My former profession is from healthcare sector, then I studied mechanical engineering (quit in the middle), then I studied product design (master degree), and I ended up working (very happily) at an engineering company that manufactures medical devices. For more than two years now my main activity in this company is software development. The devices contain software, and we gave up hiring software development (domain knowledge needed, too much communication cost). My current company sees a lot of value in what I do, but I cannot afford the risk of depending on this single company for the rest of my life, you get it. But a lot of job offers require some minimal formal education, usually a CS degree. Fact is that I am sure this is my target profession, I don't plan to go to another area, it is a pleasure to dive into books that normal people would consider unreadable, but I'm 36 years old and can't see going back to college as a viable alternative.

  • Simple (and fast) dices physics

    - by Markus von Broady
    I'm programming a throw of 5 dices in Actionscript 3 + AwayPhysics (BulletPhysics port). I had a lot of fun tweaking frictions, masses etc. and in the end I found best results with more physics ticks per frame. Currently I use 10 ticks per frame (1/60 s) and it's OK, though I see a difference in plus for 20 ticks. Even though it's only 5 cubes (dices) in a box (or a floor with 3 walls really) I can't simulate 20 ticks in a frame and keep FPS at 60 on a medium-aged PC. That's why I decided to precompute frames for animation, finishing it in around 1700 ticks in 2 seconds. The flash player is freezed for these 2 seconds, and I'm afraid that this result will be more of a 5 seconds or even more, if I'll simulate multi-threading and compute frames in background of some other heavy processes and CPU drawing (dices is only a part of this game). Because I want both players to see dices roll in same way, I can't compute physics when having free resources, and build a buffer for at least one throw of each type (where type is number of dices thrown). I'm afraid players will see a "preparing dices........." message too often and for too long. I think the only solution to this problem is replacing PhysicsEngine with something simpler, or creating own physicsEngine. Do You have any formulas for cube-cube and cube-wall collision detection, and for calculating how their angular and linear velocities should change after a collision occurs?

  • Problems moving a rectangle in Pygame.

    - by Yann Core
    Hi guys! I'm making a game in Pygame and I want to be able to target enemy unit. I made it so when I click on them a variable "targeted" becomes true, and stays true until I click somewhere else on the screen. I also want targeted units to have a small green circle around them, so I made it in GEDIT. I have made a function that draws everything on the screen (the background, the player, objects, etc) and in the part where it draws the units it checks if the variable "targeted" is true and if it is it should move that little green circle over the enemy units. here is the code that does that: screen.blit(enemy_unit.pic, enemy_unit.rect) #draw the unit if enemy_unit.targeted == True: #if the unit has been targeted then draw a circle over it target_rect.move_ip(enemy_unit.pos) #move the circle to the unit target_rect.fit(enemy_unit.rect) #there are some bigger units and some smaller ones, so we have to "scale" the circle screen.blit(target_pic, target_rect) #actually draw the circle This doesn't work, when I target the unit the circle just appears for a 1/5 of second next (not on, but just next) to the unit and then disappears. I am sure that I am keeping a good track of "enemy_unit.pos" because I tested it (I added a piece of code that would print one units position and mouse's position every time i clicked the mouse and when i was near him the numbers were same). If you could give me a hint about what I'm doing wrong. I think its in move_ip function, but I tried just move and it didn't work either (the circle didn't even show at all)!
