  • iStack for iPad

    - by Jonathan
    The below image is the current, and hopefully final, look of the front screen, the app will remember which stack site you have chosen so the user will only see this screen the first time, but they can always go back and change it. The red bar is only there when a new site is added (the StackOverflow is just a test as no site has been added since I implemented this) and can be gotten rid of by tapping the X on the right side (which isn't in the screenshot). Each column now has an edit button where the sites can be rearranged and moved from favourites to non favourites and this is persistent between app launches, moving a site in one column moves it in all of them. I've removed site icons in order to put them in properly so they load lazily and theres no UI freezing. Printing Functionality all implemented and working, thanks to systempuntoout's stackprinter.com works with AirPrint, which means this app will be iOS 4.2 minimum. Current features: 3 columns Email link to question, open in safari and copy link actions History for both questions and sites visited In app notification (red bar at the top) when a new site makes it into beta. StackPrinter in the app, without needing safari, and AirPrint functionality. Facebook Intergration Planned: Local Favourites Watching (a list of questions your watching, like short term favourites, with eventually push notifications) Web service to access local favourites and watches on non-iPad devices. Twitter integration. Safari bookmarklet to open question in iStack from safari In app notification for when site progresses from beta to normal. In app notification history

  • How to have other divs with a flash liquid layout that fits to the page?

    - by brybam
    Basically the majority of my content is flash based. I designed it using Flash Builder (Flex) and Its in a liquid layout, (everything is in percents) and if im JUST embedding the flash content it scales to the page fine, and i have the flash content set to have a padding of 50 px. I put a header div in fine with no problems, but I have 2 problems, the first being the footer div seems to cover up the buttom of the flash content in IE, but it looks just fine in chrome. How can I solve this? I'm using the stock embed code that Flex provides, I tried to edit the css style for the div which I think is #flashContent and give it a min width and min height but it didnt seem to work, actually anything I did to #flashContent didn't seem to do anything, maybe its not the div i need to be adding that attribute to... And my other problem is I dont even know where to start when it comes to placing a div thats 280width by 600height colum to the right side of the flash content. If i could specify a size for the flash content, and the float it left, and float the colum right, and clear it with the container div id be just fine....But remember the flash content is set to 100% Scale (well techically 100%x80% because it looked better that way). Does anyone know how I can start to deal with creating a more complex scaleable flash layouts that includes other divs? ALL WELL MAINTAINING IE SUPPORT? IE is ruining my life. Here's the code I'm using: (or if it will help you visualize what im trying to do here's the page where im working on setting this up http://apumpkinpatch.com/textmashnew/) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <title>TextMixup</title> <meta name="google" value="notranslate"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link href="css.css" rel="stylesheet" type="text/css" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script> <script src="../appassets/scripts/jquery.titlealert.js"></script> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-19768131-2']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

  • BUILD 2013&ndash;Day 2 Summary

    - by Tim Murphy
    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/28/build-2013ndashday-2-summary.aspx Day 1 rocked.  So how could they top that?  By having more goodies to give away!  During the keynote they announced that attendees would get one year of Office 365, 100 GB of SkyDrive and one year of Adobe Cloud Service.  Overall they key note was long with more information shot at you than you could possibly absorb.  They went about 20 minutes over time which made me think that they could have split it to a 3rd keynote and given us a better idea on some of these topics and perhaps addressed the one open question that was floating around Twitter.  That is, what is going to happen with XBox development.  It sounded like there was a quick side mention of that, but I missed it. The rest of the day was packed with great sessions full of Windows 8, Azure and Windows Phone goodness.  I had planned on attending Scott Hanselman’s talk, but they had so many people this they had to push to an overflow room.  Stay tuned from session summaries later. The day was topped off by an attendee party across from the San Francisco Giant’s ball park.  It was kind of quirky and and fun.  They set it up on one of the piers in the bay and had food served by food trucks.  You would be surprised how good the food was.  Add in some pool tables, fooseball, video games, a DJ, a comedian/musician and plenty of spirits and it was a great way to end day 2. del.icio.us Tags: BUILD 2013

  • How to open a VirtualBox (.VDI) Virtual Machine

    - by [email protected]
     How to open a .VDI Virtual MachineSometimes someone share with us one Virtual machine with extension .VDI, after that we can wonder how and what with?Well the answer is... It is a VirtualBox - Virtual Machine. If you have not downloaded it you can do this easily, just follow this post.http://listeningoracle.blogspot.com/2010/04/que-es-virtualbox.htmlorhttp://oracleoforacle.wordpress.com/2010/04/14/ques-es-virtualbox/Ok, Now with VirtualBox Installed open it and proceed with the following:1. Open the Virtual File Manager. 2. Click on Actions ? Add and select the .VDI fileClick "Ok"3.  A new Virtual machine will be displayed, (in this Case, an OEL5 32GB Virtual Machine is available.)4. This step is important. Once you have open the settings, under General option click the advanced settings. Here you must change the default directory to save your Snapshots; my recommendation set it to the same directory where the .Vdi file is. Otherwise you can have the same Virtual Machine and its snapshots in different paths.5. Now Click on System, and proceed to assign the correct memory and define the processors for the Virtual machine. Note: Enable  "Enable IO APIC" if you are planning to assign more than one CPU to the Virtual Machine.6. Associated the storage disk to the Virtual machineThe disk must be selected as IDE Primary Master. 7. Well you can verify the other options, but with these changes you will be able to start the VM. Note: Sometime the VM owner may share some instructions, if so follow his instructions.8.

  • Is a code review which uses only code comments a good idea?

    - by gaRex
    Preconditions Team uses DVCS IDE supports comments parsing (like TODO and etc.) Tools like CodeCollaborator are expensive for budget Tools like gerrit are too complex for install or not usable Workflow Author publishes somewhere on central repo feature branch Reviewer fetch it and start review In case of some question/issue reviewer create comment with special label, like "REV". Such label MUST not be in production code -- only on review stage: $somevar = 123; // REV Why do echo this here? echo $somevar; When reviewer finish post comments -- it just commits with stupid message "comments" and pushes back Author pulls feature branch back and answer comments in similar way or improve code and push it back When "REV" comments have gone we can think, that review has successfully finished. Author interactively rebases feature branch, squashes it to remove those "comment" commits and now is ready to merge feature to develop or make any action that usualy could be after successful internal review IDE support I know, that custom comment tags are possible in eclipse & netbeans. Sure it also should be in blablaStorm family. Questions Do you think this methodology is viable? Do you know something similar? What can be improved in it?

  • iOS: Using Jenkins for nightly internal builds (TestFlight), plus frequent client builds

    - by Amy Worrall
    I'm an iOS dev, working for a small agency. I'm currently on a few smaller projects where I'm the only developer. We recently acquired a Jenkins server, but each project is left to fend for themselves as for how to use it. I'd like to use it for making and distributing builds. My ideal would be: Every commit is built as a single IPA that is placed in a HTTP-accessible location. (It only needs to keep the latest one, otherwise the disk would fill up — some of our apps are 500MB or more.) Once a day it makes a build, signs it with our internal provisioning profile, tacks a build number onto the end of the version number, and sends it to our internal TestFlight team. When manually prompted, it builds the latest commit, gives it a manually specified version number, signs it with the client's provisioning profile and sends it to TestFlight. I'm pretty new to Jenkins. The developer who set up the server is running it on one of our projects, so I know it has the right stuff installed to do Xcode builds. I believe he's only using it to run unit tests though, not to do any of the code signing, IPA creation or TestFlight stuff. So my questions: I've listed three distinct kinds of build. How does Jenkins cope with that? I see there's a "build triggers" section in the config for a Jenkins project, but it doesn't seem to mention different types of build. Should I just set up multiple Jenkins projects, called "App X (continuous)", "App X (nightly)" and "App X (client)"? How do I specify the provisioning profile through Jenkins? If there isn't a way, I guess I could make different configurations in the Xcode project… Has anyone else used Jenkins to actually do the release (i.e. build and push to TestFlight) of beta builds of their apps? Is it a good idea? Or should I continue just doing it manually?

  • Game Components, Game Managers and Object Properties

    - by George Duckett
    I'm trying to get my head around component based entity design. My first step was to create various components that could be added to an object. For every component type i had a manager, which would call every component's update function, passing in things like keyboard state etc. as required. The next thing i did was remove the object, and just have each component with an Id. So an object is defined by components having the same Ids. Now, i'm thinking that i don't need a manager for all my components, for example i have a SizeComponent, which just has a Size property). As a result the SizeComponent doesn't have an update method, and the manager's update method does nothing. My first thought was to have an ObjectProperty class which components could query, instead of having them as properties of components. So an object would have a number of ObjectProperty and ObjectComponent. Components would have update logic that queries the object for properties. The manager would manage calling the component's update method. This seems like over-engineering to me, but i don't think i can get rid of the components, because i need a way for the managers to know what objects need what component logic to run (otherwise i'd just remove the component completely and push its update logic into the manager). Is this (having ObjectProperty, ObjectComponent and ComponentManager classes) over-engineering? What would be a good alternative?

  • How to implement Facebook leaderboard game for mobile?

    - by TrueGrime
    I am in the final stages of developing an indie C# mobile game that I will deploy to iPhones and Androids using Mono. I wish to add push notifications and a Facebook leader board feature into the game, such that the user will be presented with a list of all his/her friends that are playing the game and their weekly scores in the main screen. I have ZERO experience with web development/networking/databases. I recently started researching the field and formed a basic understanding. Facebook has SDKs in PHP, JavaScript, obj-c and java, tho reading the documentation examples still feels cryptic to me since it involves web/server tech. After researching some more, I understood that my options for server side are basically PHP or ASP.Net. It seems that ASP.Net is more favorable in my case since I am already proficient with C# (but there is no ASP.net SDK from Facebook... I am not sure if this implies that I cant interact with Facebook using ASP.Net). On the down side some have mentioned higher costs for ASP.Net, tho I havent looked further into that aspect yet. I also understood that JavaScript is client side technology. I started going through tutorials of ASP.Net, I was thinking that ASP.Net is a purely server side management language, but it started feeling more like WPF as those tutorials started getting into very lengthy discussions about creating website interfaces and styles. I am not interested in that, I just want to have a web server which my app can somehow communicate with and get friends/scores. Am I learning the right technologies for my goal? should I be learning something else? I am posting this in hopes that someone who knows this field well can see through my problem and help guide me, otherwise I could spend months studying something that might not be the right solution to my goal. Thanks.

  • 10 Windows Tweaking Myths Debunked

    - by Chris Hoffman
    Windows is big, complicated, and misunderstood. You’ll still stumble across bad advice from time to time when browsing the web. These Windows tweaking, performance, and system maintenance tips are mostly just useless, but some are actively harmful. Luckily, most of these myths have been stomped out on mainstream sites and forums. However, if you start searching the web, you’ll still find websites that recommend you do these things. Erase Cache Files Regularly to Speed Things Up You can free up disk space by running an application like CCleaner, another temporary-file-cleaning utility, or even the Windows Disk Cleanup tool. In some cases, you may even see an old computer speed up when you erase a large amount of useless files. However, running CCleaner or similar utilities every day to erase your browser’s cache won’t actually speed things up. It will slow down your web browsing as your web browser is forced to redownload the files all over again, and reconstruct the cache you regularly delete. If you’ve installed CCleaner or a similar program and run it every day with the default settings, you’re actually slowing down your web browsing. Consider at least preventing the program from wiping out your web browser cache. Enable ReadyBoost to Speed Up Modern PCs Windows still prompts you to enable ReadyBoost when you insert a USB stick or memory card. On modern computers, this is completely pointless — ReadyBoost won’t actually speed up your computer if you have at least 1 GB of RAM. If you have a very old computer with a tiny amount of RAM — think 512 MB — ReadyBoost may help a bit. Otherwise, don’t bother. Open the Disk Defragmenter and Manually Defragment On Windows 98, users had to manually open the defragmentation tool and run it, ensuring no other applications were using the hard drive while it did its work. Modern versions of Windows are capable of defragmenting your file system while other programs are using it, and they automatically defragment your disks for you. If you’re still opening the Disk Defragmenter every week and clicking the Defragment button, you don’t need to do this — Windows is doing it for you unless you’ve told it not to run on a schedule. Modern computers with solid-state drives don’t have to be defragmented at all. Disable Your Pagefile to Increase Performance When Windows runs out of empty space in RAM, it swaps out data from memory to a pagefile on your hard disk. If a computer doesn’t have much memory and it’s running slow, it’s probably moving data to the pagefile or reading data from it. Some Windows geeks seem to think that the pagefile is bad for system performance and disable it completely. The argument seems to be that Windows can’t be trusted to manage a pagefile and won’t use it intelligently, so the pagefile needs to be removed. As long as you have enough RAM, it’s true that you can get by without a pagefile. However, if you do have enough RAM, Windows will only use the pagefile rarely anyway. Tests have found that disabling the pagefile offers no performance benefit. Enable CPU Cores in MSConfig Some websites claim that Windows may not be using all of your CPU cores or that you can speed up your boot time by increasing the amount of cores used during boot. They direct you to the MSConfig application, where you can indeed select an option that appears to increase the amount of cores used. In reality, Windows always uses the maximum amount of processor cores your CPU has. (Technically, only one core is used at the beginning of the boot process, but the additional cores are quickly activated.) Leave this option unchecked. It’s just a debugging option that allows you to set a maximum number of cores, so it would be useful if you wanted to force Windows to only use a single core on a multi-core system — but all it can do is restrict the amount of cores used. Clean Your Prefetch To Increase Startup Speed Windows watches the programs you run and creates .pf files in its Prefetch folder for them. The Prefetch feature works as a sort of cache — when you open an application, Windows checks the Prefetch folder, looks at the application’s .pf file (if it exists), and uses that as a guide to start preloading data that the application will use. This helps your applications start faster. Some Windows geeks have misunderstood this feature. They believe that Windows loads these files at boot, so your boot time will slow down due to Windows preloading the data specified in the .pf files. They also argue you’ll build up useless files as you uninstall programs and .pf files will be left over. In reality, Windows only loads the data in these .pf files when you launch the associated application and only stores .pf files for the 128 most recently launched programs. If you were to regularly clean out the Prefetch folder, not only would programs take longer to open because they won’t be preloaded, Windows will have to waste time recreating all the .pf files. You could also modify the PrefetchParameters setting to disable Prefetch, but there’s no reason to do that. Let Windows manage Prefetch on its own. Disable QoS To Increase Network Bandwidth Quality of Service (QoS) is a feature that allows your computer to prioritize its traffic. For example, a time-critical application like Skype could choose to use QoS and prioritize its traffic over a file-downloading program so your voice conversation would work smoothly, even while you were downloading files. Some people incorrectly believe that QoS always reserves a certain amount of bandwidth and this bandwidth is unused until you disable it. This is untrue. In reality, 100% of bandwidth is normally available to all applications unless a program chooses to use QoS. Even if a program does choose to use QoS, the reserved space will be available to other programs unless the program is actively using it. No bandwidth is ever set aside and left empty. Set DisablePagingExecutive to Make Windows Faster The DisablePagingExecutive registry setting is set to 0 by default, which allows drivers and system code to be paged to the disk. When set to 1, drivers and system code will be forced to stay resident in memory. Once again, some people believe that Windows isn’t smart enough to manage the pagefile on its own and believe that changing this option will force Windows to keep important files in memory rather than stupidly paging them out. If you have more than enough memory, changing this won’t really do anything. If you have little memory, changing this setting may force Windows to push programs you’re using to the page file rather than push unused system files there — this would slow things down. This is an option that may be helpful for debugging in some situations, not a setting to change for more performance. Process Idle Tasks to Free Memory Windows does things, such as creating scheduled system restore points, when you step away from your computer. It waits until your computer is “idle” so it won’t slow your computer and waste your time while you’re using it. Running the “Rundll32.exe advapi32.dll,ProcessIdleTasks” command forces Windows to perform all of these tasks while you’re using the computer. This is completely pointless and won’t help free memory or anything like that — all you’re doing is forcing Windows to slow your computer down while you’re using it. This command only exists so benchmarking programs can force idle tasks to run before performing benchmarks, ensuring idle tasks don’t start running and interfere with the benchmark. Delay or Disable Windows Services There’s no real reason to disable Windows services anymore. There was a time when Windows was particularly heavy and computers had little memory — think Windows Vista and those “Vista Capable” PCs Microsoft was sued over. Modern versions of Windows like Windows 7 and 8 are lighter than Windows Vista and computers have more than enough memory, so you won’t see any improvements from disabling system services included with Windows. Some people argue for not disabling services, however — they recommend setting services from “Automatic” to “Automatic (Delayed Start)”. By default, the Delayed Start option just starts services two minutes after the last “Automatic” service starts. Setting services to Delayed Start won’t really speed up your boot time, as the services will still need to start — in fact, it may lengthen the time it takes to get a usable desktop as services will still be loading two minutes after booting. Most services can load in parallel, and loading the services as early as possible will result in a better experience. The “Delayed Start” feature is primarily useful for system administrators who need to ensure a specific service starts later than another service. If you ever find a guide that recommends you set a little-known registry setting to improve performance, take a closer look — the change is probably useless. Want to actually speed up your PC? Try disabling useless startup programs that run on boot, increasing your boot time and consuming memory in the background. This is a much better tip than doing any of the above, especially considering most Windows PCs come packed to the brim with bloatware.

  • AABB Sweeping, algorithm to solve "stacking box" problem

    - by Ivo Wetzel
    I'm currently working on a simple AABB collision system and after some fiddling the sweeping of a single box vs. another and the calculation of the response velocity needed to push them apart works flawlessly. Now on to the new problem, imagine I'm having a stack of boxes which are falling towards a ground box which isn't moving: Each of these boxes has a vertical velocity for the "gravity" value, let's say this velocity is 5. Now, the result is that they all fall into each other: The reason is obvious, since all the boxes have a downward velocity of 5, this results in no collisions when calculating the relative velocity between the boxes during sweeping. Note: The red ground box here is static (always 0 velocity, can utilize spatial partitioning ), and all dynamic static collisions are resolved first, thus the fact that the boxes stop correctly at this ground box. So, this seems to be simply an issue with the order the boxes are sweept against each other. I imagine that sorting the boxes based on their x and y velocities and then sweeping these groups correctly against each other may resolve this issues. So, I'm looking for algorithms / examples on how to implement such a system. The code can be found here: https://github.com/BonsaiDen/aabb The two files which are of interest are [box/Dynamic.lua][3] and [box/Manager.lua][4]. The project is using Love2D in case you want to run it.

  • Integrating different branches from external sources into a single Mercurial repository

    - by dukeofgaming
    I'm currently working in a company using Perforce and am making way for distributed version control with Mercurial. I've had success importing Perforce history using the perfarce (quite a suitable name, I laugh every time I see/say it) however, this only works with a single branch at a time. Here's how my P4 integration setup works: In perforce, create a "client", which is kind of a description of what you will be constantly updating/checking-out. This can only address one branch at a time (trunk or other). Once you do this, run hg clone p4://<server>/<client_name> Go to .hg/hgrc and put the perforce path line: perforce = p4://<server>/<client_name> Work normally with the code under mercurial, do hg pull perforce to sync up, hg push to export a changelist What I'd like to be able to do is have a perforce path per branch and have everything work in the same repository. Now, pushing is not a problem, however, if I pull the history from another branch it would end up at the default branch. I'd like to be able to do something like hg pull perforce-R5 and have it land in mercurial's R5 branch. Even if I have no merging history, it would be sweet enough to be able to preserve it. There are also other plugins for CVCSs that let you integrate mercurial, but AFAIK the subversion one has the same problem. I don't think there is a straight-through way of doing this, but as long as I could automate the process with some hooks and scripts in a single Mercurial machine, that would be good enough.

  • Cluster Nodes as RAID Drives

    - by BuckWoody
    I'm unable to sleep tonight so I thought I would push this post out VERY early. When you don't sleep your mind takes interesting turns, which can be a good thing. I was watching a briefing today by a couple of friends as they were talking about various ways to arrange a Windows Server Cluster for SQL Server. I often see an "active" node of a cluster with a "passive" node backing it up. That means one node is working and accepting transactions, and the other is not doing any work but simply "standing by" waiting for the first to fail over. The configuration in the demonstration I saw was a bit different. In this example, there were three nodes that were actively working, and a fourth standing by for all three. I've put configurations like this one into place before, but as I was looking at their architecture diagram, it looked familar - it looked like a RAID drive setup! And that's not a bad way to think about your cluster arrangements. The same concerns you might think about for a particular RAID configuration provides a good way to think about protecting your systems in general. So even if you're not staying awake all night thinking about SQL Server clusters, take this post as an opportunity for "lateral thinking" - a way of combining in your mind the concepts from one piece of knowledge to another. You might find a new way of making your technical environment a little better. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • As a solo programmer, of what use can Gerrit be?

    - by s.d
    Disclaimer: I'm aware of the questions How do I review my own code? and What advantages do continuous integration tools offer on a solo project?. I do feel that this question aims at a different set of answers though, as it is about a specific software, and not about general musings about the use of this or that practice or tech stack. I'm a solo programmer for an Eclipse RCP-based project. To be able to control myself and the quality of my software, I'm in the process of setting up a CSI stack. In this, I follow the Eclipse Common Build Infrastructure guidelines, with the exception that I will use Jenkins rather than Hudson. Sticking to these guidelines will hopefully help me in getting used to the Eclipse way of doing things, and I hope to be able to contribute some code to Eclipse in the future. However, CBI includes Gerrit, a code review software. While I think it's really helpful for teams, and I will employ it as soon as the team grows to at least two developers, I'm wondering how I could use it while I'm still solo. Question: Is there a use case for Gerrit that takes into account solo developers? Notes: I can imagine reviewing code myself after a certain amount of time to gain a little distance to it. This does complicate the workflow though, as code will only be built once it's been passed through code review. This might prove to be a "trap" as I might be tempted to quickly push bad code through Gerrit just to get it built. I'm very interested in hearing how other solo devs have made use of Gerrit.

  • Connection timeout when accessing Github

    - by Felipe Micaroni Lalli
    I have exactly the same problem as described here: http://stackoverflow.com/questions/12849986/connection-timeout-when-accessing-github So I'll just copy & paste: I have some weird problems. When I try to log in my Github account, I get a "net::ERR_EMPTY_RESPONSE" error. I tried with Chrome, Firefox and Opera. In Firefox, if a clean the cache and offline data, it works for a while. Then I can log in, but I still can't create a Github repository, even if I clear the cache again. My friend, in the same network, with Windows, can do whatever he wants on Github's web site, but I can't. I tried many DNS servers, I tried not to set it (my friend doesn't), but it's still not working. My OS: Ubuntu x64 12.04 Ideas, please. And thanks. Also, I can clone any repo but I can't push. I had to change to https://codeplane.com/ due to this problem, but I want to understand why it happens. EDIT: I could clone one repo, but the other one just hangs at this point: felipelalli@felipelalli-Studio-XPS-8100:~/wa$ git clone [email protected]:felipelalli/micaroni.git Cloning into 'micaroni'... remote: Counting objects: 5238, done. remote: Compressing objects: 100% (3257/3257), done.

  • Best practice with branching source code and application lifecycle

    - by Toni Frankola
    We are a small ISV shop and we usually ship a new version of our products every month. We use Subversion as our code repository and Visual Studio 2010 as our IDE. I am aware a lot of people are advocating Mercurial and other distributed source control systems but at this point I do not see how we could benefit from these, but I might be wrong. Our main problem is how to keep branches and main trunk in sync. Here is how we do things today: Release new version (automatically create a tag in Subversion) Continue working on the main trunk that will be released next month And the cycle repeats every month and works perfectly. The problem arises when an urgent service release needs to be released. We cannot release it from the main trunk (2) as it is under heavy development and it is not stable enough to be released urgently. In such case we do the following: Create a branch from the tag we created in step (1) Bug fix Test and release Push the change back to main trunk (if applicable) Our biggest problem is merging these two (branch with main). In most cases we cannot rely on automatic merging because e.g.: a lot of changes has been made to main trunk merging complex files (like Visual Studio XML files etc.) does not work very well another developer / team made changes you do not understand and you cannot just merge it So what you think is the best practice to keep these two different versions (branch and main) in sync. What do you do?

  • Programming as a minor

    - by Tomas Cokis
    Hello Everyone! I've never asked a question here at programmers, and for reasons which will become obvious later I've never answered one here, but I do poke around in short bursts. Anyway, I'm 15 right now, and I've been programming in C++ for 4 years, just working on my own projects that are aim so high as to never be finished. I've been working on a single project for the last year, and every 3 months, I add a new system into it. It might be a value tabling directory enabled log system, or a render system, or a class to load up xml files, whatever it is, I don't mind too much that the overall project (a 3d engine) isn't ever going to get finished, I just get some satisfaction from getting what I have done building and running. I don't know what I want to do when I grow up, although I suspect I'll go into some form of engineering, but I was interested in knowing if I do choose to go into a career as a developer, what kind of material I could look at to push myself up and get myself experience that might help my career later. I'm not talking about books in particular, I'm more interested in subjects areas that will get me access to good job opportunities, or that will give me a hand-up if I do computer science and software related courses at uni. One of the things I was thinking of doing was designing some of the logic gate components of a small computer - which I started briefly over the holidays, working out integer addition, subtraction and multiplication. That kind of stuff interests me, but is it really useful - or more useful then just more programming? But anyway, Any advice? Should I continue on my perpetual 3d engine? Are there any other projects or particular accomplishments that would help my education? Perhaps I should mention that I live in Perth, Australia, so local software companies are likely to be more scarce then usual.

  • Drawing particles with CPU instead of GPU (XNA)

    - by Helix
    I'm trying out modifications to the following particle system. http://create.msdn.com/en-US/education/catalog/sample/particle_3d I have a function such that when I press Space, all the particles have their positions and velocities set to 0. for (int i = 0; i < particles.GetLength(0); i++) { particles[i].Position = Vector3.Zero; particles[i].Velocity = Vector3.Zero; } However, when I press space, the particles are still moving. If I go to FireParticleSystem.cs I can turn settings.Gravity to 0 and the particles stop moving, but the particles are still not being shifted to (0,0,0). As I understand it, the problem lies in the fact that the GPU is processing all the particle positions, and it's calculating where the particles should be based on their initial position, their initial velocity and multiplying by their age. Therefore, all I've been able to do is change the initial position and velocity of particles, but I'm unable to do it on the fly since the GPU is handling everything. I want the CPU to calculate the positions of the particles individually. This is because I will be later implementing some sort of wind to push the particles around. How do I stop the GPU from taking over? I think it's something to do with VertexBuffers and the draw function, but I don't know how to modify it to make it work.

  • New cloud development workflow using Github, Cloud9ide and CloudFoundry.

    - by weng
    So time is changing towards cloud development/computing. I'm trying to get the new "cloud" workflow based on the services I'm going to use: Github, Cloud9ide and CloudFoundry. Here is what is on my mind: Github acts like a central (main repo) just like yesterday's local filesystem. Every service will base it service upon this main repo. Workflow: Github: I create a new Github repo served as main repo for the project. Cloud9ide. I open my Github repo and write my tests and implementation (BDD/TDD). When I'm ready I save (commit) it to main repo on Github. X: A running instance of Jenkins detects someone has committed and fetches the latest commit, builds, deploys, tests (yeti and/or selenium) and reports if the tests were passed or not. If not, I make another commit til all tests are passing. X: I run the CloudFoundry commands to push the main Github repo to CloudFoundry's server and it will deploy my app automatically. What I'm still confused about is where this X environment will be. On a local server where I have to install Jenkins? Or could I install it on Cloud9ide (when java is supported) or will it be on another cloud service? Also, that X environment has to be able to fetch (clone) the Github repo and run the build scripts. And since the concept of Cloud9ide is very new and there haven't been any other predecessors I really wonder how the workflow will look like. We all know Github's workflow. We now know CloudFoundry's workflow (deploy/scale with a restful API/command line tool). But how Cloud9Ide will operate is still somewhat unclear to me. Someone on Cloud9ide mentioned that there will be buttons like deploy so I can deploy with one click. But that I guess will depend on what services that deploy process will hook up into etc. Could someone enlighten this cloud workflow topic and fill in the gaps. Thanks.

  • Command-Query-Separation and multithreading safe interfaces

    - by Tobias Langner
    I like the command query separation pattern (from OOSC / Eiffel - basically you either return a value or you change the state of the class - but not both). This makes reasoning about the class easier and it is easier to write exception safe classes. Now, with multi threading, I run into a major problem: the separation of the query and the command basically invalidates the result from the query as anything can happen between those 2. So my question is: how do you handle command query separation in an multi-threaded environment? Clarification example: A stack with command query separation would have the following methods: push (command) pop (command - but does not return a value) top (query - returns the value) empty (query) The problem here is - I can get empty as status, but then I can not rely on top really retrieving an element since between the call of empty and the call of top, the stack might have been emptied. Same goes for pop & top. If I get an item using top, I can not be sure that the item that I pop is the same. This can be solved using external locks - but that's not exactly what I call threadsafe design.

  • Security in a private web service

    - by Oni
    I am developing a web site and a web service for a small on-line game. Technically, I'll be using Express (node.js) and MongoDB+Redis for the databases. This the structure I came up with: One Express server that will server as the Web Service. This will connect to the databases. One Express server that will provide the web site. It will connect to the Web Service to retrieve and push the information. iOS and Android application will be able to interact with the WebService. Taking into account: It is a small game. The information transferred is not critical. There will NOT be third party applications. At least for the moment. My concern is about which level of security I should use in each of the scenarios: Security of the user playing through web browser Security of the applications and the Web Server connecting to the WS. I have take a look at the different options and: OAuth and/or Https is too much for this scenario, isn't it? Will be a good option to hash the user and password with MD5(or similar) and some salt? I would like to get some directions and investigate by my own rather than getting a response like "you should you use this node.js module..." Thanks in advance,

  • How to implement a stack of game states in C++

    - by Lisandro Vaccaro
    I'm new to C++ and as a college proyect I'm building a 2D platformer with some classmates, I recently read that it's a good idea to have a stack of gamestates instead of a single global variable with the game state (which is what I have now) but I'm not sure how to do it. Currently this is my implementation: class GameState { public: virtual ~GameState(){}; virtual void handle_events() = 0; virtual void logic() = 0; virtual void render() = 0; }; class Menu : public GameState { public: Menu(); ~Menu(); void handle_events(); void logic(); void render(); }; Then I have a global variable of type GameState: GameState *currentState = NULL; And in my Main I define the currentState and call it's methods: int main(){ currentState = new Menu(); currentState.handle_events(); } How can I implement a stack or something similar to go from that to something like this: int main(){ statesStack.push(new Menu()); statesStack.getTop().handle_events(); }

  • How to protect Google Ads from yontoo layers runtime?

    - by Dharmavir
    Since sometime I have observed that Google Ads on any website including my blog (http://blogs.digitss.com) gets replaced with something similar to uploaded image below. I am sure it's happening with many people and that could reduce google adsense income. After some research I found that it is because "yontoo layers runtime" from http://www.yontoo.com/ (tagline says: Platform that allows you to control the websites you visit everyday.) but actually they are taking over. I am not sure with which software they are making a way into users computer but that seems very bad in terms of freedom of Internet and advt/marketing industry. I don't remember I have ever said "yes" to install yontoo on my computer. This piece of software is successful to install itself on my laptop/desktop and workstation at office. I am going to disable it now but the question is how do I make my websites aware of Yontoo Runtime and stop them from replacing Google Ads? Basically they are not able to replace all adsense ads but so far they are successfully replaced 1st instance of adsense advt and I am sure in future they will hit more. There could be 2 approaches 1) Fool yontoo runtime by putting some misleading divs in html document to save actual ads, 2) Completely disable yontoo by working out some client side script (javascript) which can fail/crash yontoo runtime and so will fail it's purpose of replacing ads. You can visit my blog (http://blogs.digitss.com) and see on top-right corner, if you find that google ad replaced with something similar to image attached with question - it means your computer/browser is infected too. Looking forward to reply from webmasters, if someone has already wrote some code/plugin to make website (and google ads) safe from yontoo or similar runtime. FYI: it was able to push this runtime in all browsers installed on machine. So a dangerous threat. And yes, I am just using Google ads - not sure if yontoo runtime is doing trick against other ad networks or not? I am sure they must be doing it with some handful of ad networks.
