  • Deferent ways of solving problems in code.

    - by Erin
    I now program in C# for a living but before that I programmed in python for 5 years. I have found that I write C# very that most examples I see on the web. Rather then writing things like: foreach (string bar in foo) { //bar has something doen to it here } I write code that looks like this. foo.ForEach( c => c.someActionhere() ) Or var result = foo.Select( c => { //Some code here to transform the item. }).ToList(); I think my using code like above came form my love of map and reduce in python while not exactly the same thing the concepts are close. Now it's time for my question. What concepts do you take and move with you from language to language. That allow you to solve a problem in a way that is not the normal accepted solution in that language?

  • How large should I make root, home, and swap partitions?

    - by starcorn
    Hello, I have a laptop with win7 installed. I have now made a 60gb partition which I want to install ubuntu into. The question I have, before I do the installation, is how large each of the root, swap, and home partition should be? I have read some place that root could be as small as 8GB, but isn't that too small? Since I guess beside ubuntu all the softwares installed will reside there as well? And I think I'm going to set my swap to be 2GB large. My main concern is how large should the root partition should be. I'm mainly going to use ubuntu for programming and browse the web.

  • Is there a formal name for gradually activating software changes?

    - by g .
    At times when we develop new features or functionality, we gradually "turn it on" to ensure a smooth transition and minimal impact for users. Instead of one big sudden change, we are able to control with the configuration aspects of the functionality that make it more or less intrusive to the user. This is all done in the same release/version of the software, so no software development changes are required (unless bugs turn up that need to be fixed). For example, initially we may only perform logging or analysis of data without acting upon it. Or we make something optional for a period of time before it becomes compulsory. The idea is that this reduces the potential for problems either on the technical side as well as unexpected changes by the user. The question is, is there a formal name for this approach?

  • Will 3D games run in a VirtualBox4-hosted Windows system under Ubuntu with Intel GMA X4500HD card?

    - by Ivan
    I've just got a laptop with Intel GMA X4500HD card (which is said to be DirectX10-compliant, while my previous laptop had Intel 82852/855GM and no chance to play modern 3D games at all). It would be nice if I could play some games (like HalfLife 2, StarCraft 2, Fallout 3) from time to time (while I am ok using lo-fi settings and having low performance) but as I strongly prefer Ubuntu environment and don't need Windows usually I'd like to install Windows inside VirtualBox instead of using a dedicated partition and dual-boot. So the question is if VirtualBox can use 3D acceleration of Intel GMA X4500HD if run on Ubuntu.

  • E-Commerce Website

    - by haargott
    I am planning to create an e-commerce website for users to buy products and services. In this website I want users to register and also participate in something like a browser game, where every user may receive some questions which they have to answer. For each question they successfully answered, they receive points and the number of collected points will decide on which rank they are. Edit 2 Currently I am considering using only HTML, CSS, JavaScript, PHP, SQL to design this e-commerce website. Together with this I was thinking about learning jQuery as it may help me, but I am not sure if I should code everything specifically by myself or just use the library to make it faster. 1) Could you tell me if those languages are sufficient enough for creating such a website described? 2) Could you tell me what kind of free software tools and frameworks are most appropriate to use when creating this e-commerce website?

  • Given two sets of DNA, what does it take to computationally "grow" that person from a fertilised egg and see what they become? [closed]

    - by Nicholas Hill
    My question is essentially entirely in the title, but let me add some points to prevent some "why on earth would you want to do that" sort of answers: This is more of a mind experiment than an attempt to implement real software. For fun. Don't worry about computational speed or the number of available memory bytes. Computers get faster and better all of the time. Imagine we have two data files: Mother.dna and Father.dna. What else would be required? (Bonus point for someone who tells me approx how many GB each file will be, and if the size of the files are exactly the same number of bytes for everyone alive on Earth!) There would ideally need to be a way to see what the egg becomes as it becomes a human adult. If you fancy, feel free to outline the design. I am initially thinking that there'd need to be some sort of volumetric voxel-based 3D environment for simulation purposes.

  • How can I designed multi-threaded application for larger user base

    - by rokonoid
    Here's my scenario, I need to develop a scalable application. My user base may be over 100K, every user has 10 or more small tasks. Tasks check every minute with a third party application through web services, retrieving data which is written in the database, then the data is forwarded to it's original destination. So here's the processing of a small task: while(true){ Boolean isNewInformationAvailable = checkWhetherInformationIsAvailableOrNot(); If(isNewInformationAvailable ==true){ fetchTheData(); writeToDatabase(); findTheDestination(); deliverTheData(); isAvailable =false; } } Here is the question: as the application is large, how should I approach designing this. I'm going to use Java to write it. Should I use concurrency, and how would you manage the concurrency?

  • How to identify a PDF classification problem?

    - by burtonic
    We are crawling and downloading lots of companies' PDFs and trying to pick out the ones that are Annual Reports. Such reports can be downloaded from most companies' investor-relations pages. The PDFs are scanned and the database is populated with, among other things, the: Title Contents (full text) Page count Word count Orientation First line Using this data we are checking for the obvious phrases such as: Annual report Financial statement Quarterly report Interim report Then recording the frequency of these phrases and others. So far we have around 350,000 PDFs to scan and a training set of 4,000 documents that have been manually classified as either a report or not. We are experimenting with a number of different approaches including Bayesian classifiers and weighting the different factors available. We are building the classifier in Ruby. My question is: if you were thinking about this problem, where would you start?

  • Adobe Air apps on the Mac App Store?

    - by coneybeare
    Before you chastise me for asking this, I have an Adobe Air app that has a lot of investment in it, and if there is a way to utilize the existing code-base in any way, it is worth considering. I have heard news reports in passing about Adobe creating some kind of tool to allow flash or air apps to be ported to native objective-c code, but the information found in google is mostly commentary on the one-time Apple blockade. My question(s) is/are this: Is it even possible, at any level, to use an existing Air app to create a Mac Store app? If possible, what are the resources I can use to accomplish this?

  • Need some advice on CLI design, I need to provide simple but powerful command line options

    - by howtechstuffworks
    I am writing a utility that runs on RHEL5 command line. I need my command line options to be simple but powerful. I looked at the various UNIX utilities to get an idea of how simple command line utilities have to be. Do you guys suggest any documents/links that talk about command line etiquette? I am modelling my utility on top of LVM (that's all the info I can give for now). I know it's a software engineering question, but I thought it would be appropriate to post here. Please advise.... PS: I am not asking for details about getopt or command line utility parsers.....

  • Performance impact of not implementing relationships at the database level?

    - by JVerstry
    Let's imagine a data model with customers and invoices. There is a 1 to n relationship between a customer and its invoices. We uses an ORM (like Hibernate). One can explicitely implement the 1-n relationship (using JPA for example) or not. If not, then one must do a bit more work to fetch invoices. However, it is much easier to maintain, improve and develop the data model of applications where relationships between objects are not explicitely implemented in the database. My question is, has anyone noticed a significant performance impact when not implementing the relationships in the database?

  • How to run Virtualbox on bridged and host-only networks?

    - by ril44
    I wish to run VirtualBox with my Ubuntu laptop on the home network (so the desktop PC can access it through the router) and also be able to ssh into the VirtualBox from host on the go (different network or with no internet). Previously, the only network adapter on the VB instance was a 'bridged connection' adapter. This allowed me to access the internet on the guest VB and for the other computers on the LAN + host to access it. However, whenever I took my laptop off the network, I could no longer access the guest from host. I read that I needed to enable a host-only adapter to access it off the network and a NAT adapter is used to access the internet from guest. My question is can I run a host-only adapter + a NAT adapter alongside a bridged network adapter in VirtualBox? I am confused what I would put inside /etc/hosts? Would I put both IP's (host-only and bridged) with the same servername in /etc/hosts?

  • How to handle a Tile Map Scrolling [duplicate]

    - by DGomez
    This question already has an answer here: Implementing a camera / viewport to a 2D game 1 answer i'm making a video game, and i'm having, i think, a concept problem. The game will be a platformer which will use tile maps, so to start i will create a mask matrix indicating the tiles to be loaded, and etc..., so my problem is, how to handle the scrolling? should i create a giant mask matrix indicating in each position of the whole level what is supposed to be loaded, and according to the position of the player, change the section to be drawed?? Is this a correct approach to this situation??

  • What do you miss when you have to use C instead of C++?

    - by sharkin
    This is not a question about which of the two languages is better than the other. I myself can't really decide. Pros and cons as always I guess. Also, if you feel you always would prefer C over C++, this poll is not for you :-). However, when I work in C projects I usually feel I'm missing a few language constructs more than others, which can be found in C++. For example, I usually miss (the obvious) classes, but seldomly templates (I always miss STL, but wouldn't call it a language construct). What do you miss when you have to use C instead of C++?

  • How do you ensure consistent experience across multiple graphics cards (or even driver versions)?

    - by Grigory Javadyan
    So I was writing a simple 2D game with OpenGL and SDL and had this problem when there was awful tearing when running in windowed mode (even though I explicitly asked SDL_SetVideoMode to use double buffering). Didn't worry about it all too much because most of the time the game grabs the entire screen, windowed mode is just for debugging. Anyway, yesterday I updated my nVidia drivers and tearing disappeared, the game runs smooth and looks nice in windowed mode too. I can see how the problem may be in the graphics driver, but this leads to a question. Obviously, professional game developers have to deal with a lot of different hardware/software configurations. What are the techniques they use to make sure the game looks the roughly the same on different graphics cards or even the same model of graphics card, but with different driver versions?

    I have a fairly simple question that I've tried to get help from the guys on the Google Webmaster Help Q&A site but so far no joy so hopefully someone here can provide me with the information I'm looking for. I have a Facebook fanpage for my website, I have made an app that basically uses an iframe and puts the site within a frame within Facebook. All works good but Google is not indexing this page. I am using <link rel="canonical" href="#" /> on my pages so prehaps this is an issue?

  • Unit testing multiple conditions in an IF statement

    - by bwalk2895
    I have a chunk of code that looks something like this: function bool PassesBusinessRules() { bool meetsBusinessRules = false; if (PassesBusinessRule1 && PassesBusinessRule2 && PassesBusinessRule3) { meetsBusinessRules= true; } return meetsBusinessRules; } I believe there should be four unit tests for this particular function. Three to test each of the conditions in the if statement and ensure it returns false. And another test that makes sure the function returns true. Question: Should there actually be ten unit tests instead? Nine that checks each of the possible failure paths. IE: False False False False False True False True False And so on for each possible combination. I think that is overkill, but some of the other members on my team do not. The way I look at it is if BusinessRule1 fails then it should always return false, it doesn't matter if it was checked first or last.

I recently discussed & visited some of the websites which states that java is better then .net, a I also discussed with some of the experience persons all suggested me to switch to java of course spring, struts etc. As Java developer is being paid high then .net one. I personally think I should go for web services SOAP, XML etc. thanks to all for response I also want to know if I can only move to webservices ex. WCF, SOAP, XML, XSLT etc. Kindly help me I am bit confused. Thanks

  • How do I swap two objects in a GC language without triggering GC?

    - by TenFour04
    I have two array lists. that I want to swap each frame. My question is, does the variable 'temp' need to be a member variable to avoid triggering GC, assuming this method is called on dozens of objects each frame? I'm not creating a new object, just a new reference to an object. public void LateUpdate(){ ArrayList<int> temp = previousFrameCollisions; previousFrameCollisions = currentFrameCollisions; currentFrameCollisions = temp; currentFrameCollisions.clear(); } I've been told there's no reason to make a primitive into a member variable just to avoid GC, so my best guess is that this also applies to object references.

  • How does N create it's tileset?

    - by Darestium
    I am trying to recreate a Multiplayer version of the popular flash game N in java. I have a single question however. Are the tiles for the games draw or are they defined with mathamatical formulars/In code? Since I do see how they would scale up in flash if they were not. So if anyone has any ideas how I should go about creating the tileset, or how they are created in the game please let me know. You can check out the game here.

  • Managing large downloadable content on mobile devices

    - by larromba
    This is a general question of how to best manage large downloadable content on mobile devices. Lets consider a situation whereby a mobile app needs to download a number of very large content items, like HD videos, that are over 500MB but under 2GB. Now, lets assume this content delivery system should be scalable. Would it be a fair assumption that: A reputable cloud service would be needed - if so, what is a reliable and cost effective cloud service for mobile devices based on anyone's experience? Large content downloads should only be attempted over a wifi connection, so the end user doesn't incur large costs, e.g. when travelling. Downloads should carry on in the background if possible, as the user won't want to wait in an app for long periods. If the downloads don't finish, or the OS quits the app, all downloads should carry on when the app is next activated? Are there any other pitfalls anyone may have experienced when managing large content on mobile devices? Thanks.
