  • Setting coding priorities

    - by dotnetdev
    Hi, In the dev shops I've worked in, nobody has ever mentioned "coding priorities". I read this in a book or site somewhere, and sets the expectation of what priority should be first in the code. In places where this is not specified, what should the first priority be? It may sound simple to say "do what the business need requires", but that could be at the expense of performance/maintainability. Many people say maintainability first, regardless, some say fulfill the need regardless. I am a young developer, so I am probably missing the point somewhere. Of course, programming is engineering and tough because you can never have the perfect solution. Thanks

  • HD Video Peformance Unacceptable

    - by Mike Hasselbeck
    Was wondering if anyone could help me boost HD 1080p video performance on my machine? I've got an AMD Athlon X2 Dual Core processor, 2 gb RAM & an ATI Radeon 5450 video card. I've installed the latest ATI Catalyst drivers, I installed the hardware acceleration things and linked them (I believe) to VLC. Still, it's still not running as well as I would like. Any thoughts or suggestions? Any help would be much appreciated. Thanks!

  • Penny auction concept and how the timer works

    - by madi
    I am creating a penny auction site using PHP yii framework. The main consideration of the system is to update the database records of all active auctions (max 15 auctions) with the current ticker timer. I am seeking for advice on how i should design the system where every auction item will have a its own countdown timer stored in the database and when someone bids the auction item, the counter resets to 2 min. Every users who are connected to the system should see the same countdown timer for that particular auction. I am little confused on how i should design the system. Will there be a performance issue when there are frequent updates to the database (Mysql) where 15 active auctions are updated every seconds, the countdown timer decreases by a second in the database table for the particular auction. Schema Sample for auction_lots: Auction_id,startdatetime,counter_timer,status I am seeking for advice on how I should design this. Please help. Thank you!

  • How to capture the screen in DirectX 9 to a raw bitmap in memory without using D3DXSaveSurfaceToFile

    - by cloudraven
    I know that in OpenGL I can do something like this glReadBuffer( GL_FRONT ); glReadPixels( 0, 0, _width, _height, GL_RGB, GL_UNSIGNED_BYTE, _buffer ); And its pretty fast, I get the raw bitmap in _buffer. When I try to do this in DirectX. Assuming that I have a D3DDevice object I can do something like this if (SUCCEEDED(D3DDevice->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &pBackbuffer))) { HResult hr = D3DXSaveSurfaceToFileA(filename, D3DXIFF_BMP, pBackbuffer, NULL, NULL); But D3DXSaveSurfaceToFile is pretty slow, and I don't need to write the capture to disk anyway, so I was wondering if there was a faster way to do this

  • Uninstalling Ubuntu dual-boot bootrec issues

    - by Raymond Standen
    So on my laptop I am currently planning on uninstalling Ubuntu 12.04 so I can upgrade my Windows 7 partition to Windows 8, then install Ubuntu 12.10. My issue being that when I boot the Windows 7 recovery disk, I believe i Need to use cmd to run bootrec /fixboot and bootrec /fixmbr. Now, whilst fixmbr works, fixboot yields me with an error regarding an unrecognised volume. When I turn on my PC now, I am no longer met the GRUB option, so I boot straight into Windows. My question is: As such, do I still need to have fixboot run or can I just format and resize the partitions now even with the error when running fixboot?

  • Copy a Ubuntu install?

    - by Hailwood
    So short story is that I am wanting to grab my ubuntu install, back up to an external disk, delete everything from my hdd, repartition my hdd, put my ubuntu install back. Long story is. I finally got my recovery discs, so I do not need to recovery partitions, not the mention my hdd is kinda messy, So I am going to wipe it and put everything back. Thing is I don't want to have to re-install everything, I would rather just copy/paste my ubuntu install if possible. Oh, What I should also mention is that I will be dual booting windows!

  • Desktop sharing options for Ubuntu 12.04 with Unity

    - by Stefan Buynov
    I would like to be able to access my office Ubuntu 12.04 machine from home, from a Mac Mini with Mac OSX. I have a VPN and I am able to access my office machine over SSH, so connectivity is not a problem. I browsed other questions, and it seems that there are several options: VNC XRDP FreeNX (haven't heard this one before) Are there any other? I have been using Remote Desktop on Windows before, and I actually like it. Not sure how well is XRDP implemented. I also used VNC several years back, and I didn't like its performance back then - not sure if things have changed since then. As I said above, the machine I want to access is running Ubuntu 12.04, with Unity. And I am using Unity by choice - I really like it and would like to continue using it :) The client computer is running Mac OSX (Snow Leopard). Based on your previous experience what is the best setup for this environment?

  • Design a Distributed System

    - by Bonton255
    I am preparing for an interview on Distributed Systems. I have gone through a lot of text and understand the basics of the area. However, I need some examples of discussions on designing a distributed system given a scenario. For example, if I were to design a distributed system to calculate if a number N is primary or not, what will the be design of the system, what will be the impact of network latency, CPU performance, node failure, addition of nodes, time synchronization etc. If you guys could present your in-depth thoughts on this example, or point me to some similar discussion, that would be really helpful.

  • Microsoft Developers Development Laptops [closed]

    - by FidEliO
    Possible Duplicate: What should I be focusing on when building a development PC? I am a Microsoft Developer on Sharepoint and ASP.NET. I am tring to buy a new laptop since the one that I have is an old one. From my point of view, Microsoft Development tools are becomming more and more resource-consuming (I don't find a suitable reason for it though). So I thought I would go for a Lenovo U260 i-7. I do not know exactly if it is going to meet my requirement so that is why I wanted to ask specifically Microsoft Developers about the specification of CPU, RAM, and Storage Disk. Thanks in advance

  • The answer to the unfathomable question: what is meaning of error value 2147943645?

    - by Jim Lahman
    I scheduled a task to perform a windows backup of a single disk on the my server.  When I tested it, the task ran successfully – no problems, no errors; just as I expected.    However, when the task ran as scheduled, it failed with error value 2147943645.  I wondered was this the answer to life, the universe and everything in it?  No.  That is 42.    After doing some research and reviewing the task configuration, I realize that the task will only run if the user of logged on:   So, this was the answer!!  I have to configure the task to run whether the user is logged or not.  Or, else I’ll get that nasty error value.

  • Why "Fork me on github"?

    - by NoBugs
    I understand how Github works, but one thing I've been confused about is, why almost every OSS project lately has a "Fork me on Github" link on their homepage. For example, http://jqtjs.com/, http://www.daviddurman.com/flexi-color-picker/, and others. Why is this so common? Is it that they want/need code validation, checking for security/performance improvements that they may not know how to do? Is it meant to show that this is a collaborative project - you're welcome to add improvements? Do they work for Github, or want to promote their service? Oddly enough, I don't think I've seen a "Fork project on Bitbucket" logo recently. My first reaction to that logo was that the project probably needs to be modified (forked) in order to integrate it with anything useful - or that they are encouraging fragmented codebase, encouraging everyone to make their own fork of the project. But I don't think that is the intent.

  • How To Troubleshoot Internet Connection Problems

    - by Chris Hoffman
    Internet connection problems can be frustrating. Rather than mashing F5 and desperately trying to reload your favorite website when you experience a problem, here are some ways you can troubleshoot the problem and identify the cause. Ensure you check the physical connections before getting too involved with troubleshooting. Someone could have accidentally kicked the router or modem’s power cable or pulled an Ethernet cable out of a socket, causing the problem.

  • Ubuntu 12.04 shut down freezes

    - by sam
    I am using Ubuntu 12.04 for last one month without any problem. It was upgraded from Ubuntu 10.10. Recently I needed to replace my hard disk. After replacement I installed Windows 7 and Ubuntu 12.04 on the system. For some days it went ok, but now shutting down from Ubuntu is causing problems. It freezes on the text screen saying acpid=exiting checking for running unattended upgrades. After that I waited for a long time, but it didn't go off and I had to hit ctrl+alt+del to restart the system and booting from Windows and then shutting down from there. This happens every time I shut down my system from Ubuntu. I have seen many posts regarding the same kind of issues but none of the solutions reported there helped me out.

  • Lenovo Thinkpad R500 having problems resuming

    - by Nicolas Raoul
    Yesterday I installed Ubuntu 11.04 from scratch on my Thinkpad R500, leaving the default power management settings. Yesterday I closed the lid, and this morning when I opened it the laptop resumed correctly. Today during lunch the laptop went to sleep without me closing the lid, and there was no way to wake it up by typing ESC or moving the mouse or TrackPoint. No disk activity at all. When I briefly pushed the POWER button, the laptop rebooted completely, losing my opened applications. Is it a known problem with Natty/Lenovo Thinkpad R500/ATI? Any idea what could fix the problem?
