  • Unable to create context rendering error whet run OpenGL application

    - by Rodnower
    Hello, I try to run Mesa gears example and I get following error: freeglut (./gears): Unable to create direct context rendering for window 'Gears' This may hurt performance. though the application runs successfully, but I guess that in future I will have much problems with productivity. I run Linux CentOS 5 on WMvare 7. Mesa's version is 6.5 Relevant output of lspci -v gives: 00:0f.0 VGA compatible controller: VMware SVGA II Adapter (prog-if 00 [VGA controller]) Subsystem: VMware SVGA II Adapter Flags: bus master, medium devsel, latency 64, IRQ 9 I/O ports at 10d0 [size=16] Memory at d0000000 (32-bit, non-prefetchable) [size=128M] Memory at d8000000 (32-bit, non-prefetchable) [size=8M] [virtual] Expansion ROM at 30000000 [disabled] [size=32K] Capabilities: [40] Vendor Specific Information Any one have idea? There is driver of vmvare for CentOS? Thank you for ahead.

  • Remove context menu items

    - by velvetkevorkian
    When I right click on a file and select open with, there are a bunch of irrelevant entries that I will never use. A lot of them are bits of the OS (e.g. Core Image Funhouse.app on image files) or at best dubious (I doubt I will ever want to open a .txt using Illustrator). Is there any way to remove items from the Open With menu? This is on OSX Lion 10.7.5. The only questions I could find related to this were about uninstalled programs remaining in the context menu. Thanks!

  • Load balancing application servers with Alteon 2424-SSL

    - by antispam
    We are having problems with load balancing configuration and we would like to clear the situation. We need to load balance among four JavaEE web application servers. The servers are configured as host1 port 7001 host1 port 7002 host2 port 7001 host2 port 7002 Do any of you know if it is possible with Nortel 2424-SSL application switch? Which would be the best configuration for it? (vips, ports, groups, services, ...) Thank you very much.

  • Ghosting context menu clicks in WinXP

    - by Swish
    Let me preface by saying I have a lot of windows open most of the time, although not resource intensive ones, just browsers, ssh sessions, a music player, FTP client, Notepad++, IM clkients, etc. Anyway, I get a lot of weird visual "ghosting" type effects. For example when right-clicking and then selecting an option from a context menu the selected item will remain in view until I right click somewhere on the desktop. Same thing happens when selecting items from the File, Edit, etc. menu in various programs. I'm assuming this is just a result of a less than high quality video card (NVIDIA GeForce FX 5200), all the other hardware in the machine is newer higher quality, that specific video card was added after the fact for multiple monitors. I have looked all over the web for solutions and have increased the number of GDI handles for Windows, reduced the hardware accelaration on the card, etc. Any suggestions other than replace the card?

  • Does Gigabit degrade all ports to 100 megabit if there is a 100 megabit device attached?

    - by hjoelr
    Our company is buying some HP Procurve managed gigabit switches to replace some of our core switches. However, we aren't able to upgrade all of our switches from 100Mb to Gigabit switches. I think I know the answer but I'm not exactly sure. If we plug those 100Mb switches (or even a 100Mb device) into those Gigabit switches, will the performance of the entire switch drop to 100Mb or will just that one port work at 100Mb?

  • Break free of a fullscreen app on MacOS X

    - by Petruza
    How do you break free of a fullscreen app on MacOS X? There are some, mostly games, that when they become unresponsive won't allow you to switch to another app with Command-Tab, and I know no other way to close that app or get away from it. Command-W or Command-Q won't work either. Is there a shortcut to launch Activity Monitor, or Terminal, to kill the application?

  • Reverse KVM solution

    - by aksamit
    I need to setup a computer so that it can be operated from two locations. The locations are about 20 meter from each other and the user wants the experience to be the same from both locations, i.e. no remote desktop or anything like that and preferably a seamless switch. So basically I need a double set of, monitor, keyboard and mouse, and then of course link it together by some kind of suitable hardware.

  • Cisco sg100-08 connections

    - by Terix
    I have multiple computers, some have a 10/100 ethernet adapter while others have a 10/100/1000 ones. If I connect them together with the Cisco sg100-08 switch, do I keep the 1Gbit speed where possible (between two devices at 1Gbit speed) or the whole lan slows down to 100mbit? I checked Cisco website but I couldn't find this kind of information, nor I was able to register to the Cisco support to ask this question (the registration form does not work)

  • How does Windows 7 detect my switches?

    - by Daniel
    I notices in the Network overview of Windows 7 that my switches are found on the path to the gateway, which baffled me completely. The last time I checked they just took the ethernet packages and transported them to the "right" location. How does this switch detection work? Do switches alter the packages? Do they react on ICMP messages?

  • Why should I use a switched network over routed?

    - by SRobertJames
    Now that routers are affordable, why should I build a network using Layer 2 switches, which degenerate to broadcasting under poor conditions, and not just use real routing at Layer 3? Edit: Got some great replies. Let me clarify the question: Of course, at the lowest level, you want to plug your end nodes into a switch, not a router (as demonstrated by AlReece). I'm referring to switches which are used to bridge traffic between segments - that is, switches connected to other switches.

  • What does CONTROL mean in the context of the Certificate

    - by Ram

  • Java - How to change context root of a dynamic web project in eclipse

    - by Yatendra Goel
    I have developed a dynamic web project in eclipse. Now I can access it through my browser using the following url: http://localhost:8080/MyDynamicWebApp Now I want to change the access url to http://localhost:8080/app I changed the context root from the project properties | Web Project Settings | Context Root But it is not working. The web app still has the access url as earlier. I have re-deployed the application on tomcat, re-started the tomcat and have done everything that should be done but the access url is the same as earlier. I found that there were no server.xml file attached with the WARfile. The how the tomcat is determining that the context root of my web app is /MyDynamicWebApp and is allowing me to access the application through that url

  • Apache - Tomcat ProxyPass VirtualHost - Context Path

    - by Arne
    Hi, I have a problem configuring apache tomcat ProxyPass directive for two applications that have two different Contaxt Pathes in tomcat. The tomcat is running behind an apache and I use the apache to proxy path the requests to tomcat. In apache I want to access both application via a hostname instead of a context path. Scenario: tomcat https://domain:8443/app1 https://domain:8443/app2 in tomcat the applications have the context path app1 and app2 in apache I want to enable both application as follow: https://app1.host/ https://app2.host/ In apache I have created a configuration for each domain: ProxyPass / https://localhost:8443/app1 ProxyPassReverse / https://localhost:/8443/app1 The strange thing is app1 is only available through apache using the context path: https://app1.host/app1 Is it possible to realize such a setup with apache ProxyPass module? Thx for your help.

  • How to dispose data context after usage

    - by Erwin
    Hi fellow programmer I have a member class that returned IQueryable from a data context public static IQueryable<TB_Country> GetCountriesQ() { IQueryable<TB_Country> country; Bn_Master_DataDataContext db = new Bn_Master_DataDataContext(); country = db.TB_Countries .OrderBy(o => o.CountryName); return country; } As you can see I don't delete the data context after usage. Because if I delete it, the code that call this method cannot use the IQueryable (perhaps because of deferred execution?). How to force immediate execution to this method? So I can dispose the data context.. Thank you :D

  • Using sphinx to create context sensitive html help

    - by bluebill
    Hi all, I am currently using AsciiDoc (http://www.methods.co.nz/asciidoc/) for documenting my software projects because it supports pdf and html help generation. I am currently running it through cygwin so that the a2x tool chain functions properly. This works well for me but is a pain to setup on other windows computers. I have been looking for alternative methods and recently revisited Sphinx. Noticing that it now produces html help files I gave it a try and it seems to work well in the small tests I performed. My question is, is there a way to specify map id's for context sensitive help in the text so that my windows programs can call the proper help api and the file is launched and opened to the desired location? In AsciiDoc I am using "pass::[]". By using these constructs a context.h and alias.h are generated along with the other html help files (context sensitive help information).

  • Creating a mask from a graphics context

    - by Magic Bullet Dave
    I want to be able to create a greyscale image with no alpha from a png in the app bundle. This works, and I get an image created: // Create graphics context the size of the overlapping rectangle UIGraphicsBeginImageContext(rectangleOfOverlap.size); CGContextRef ctx = UIGraphicsGetCurrentContext(); // More stuff CGContextDrawImage(ctx, drawRect2, [UIImage imageNamed:@"Image 01.png"].CGImage); // Create the new UIImage from the context UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); However the resulting image is 32 bits per pixel and has an alpha channel, so when I use CGCreateImageWithMask it doesn't work. I've tried creating a bitmap context thus: CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceGray(); CGContextRef ctx =CGBitmapContextCreate(nil, rectangleOfOverlap.size.width, rectangleOfOverlap.size.height, 8, rectangleOfOverlap.size.width , colorSpace, kCGImageAlphaNone); UIGraphicsGetImageFromCurrentImageContext returns zero and the resulting image is not created. Am I doing something dumb here? Any help would be greatly appreciated. Regards Dave

  • State pattern: Why doesn't the context class implement or inherit the State abstract interface/class

    - by Ricket
    I'm reading about the State pattern. I have only just begun, so of course I begin by reading the entire Wikipedia article on it. I noticed that both of the examples in the article have some base abstract class or Java interface for a generic State's methods/functions. Then there are some states which inherit from the base and implement those methods/functions in different ways. Then there's a Context class which has a private member of type State and which, at any time, can be equal to an instance of one of the implementations. That context class also implements the same methods, and passes them onto the current state instance, and then has an additional method to change the state (or depending on design I understand the change of state could be a reaction to one of the implemented methods). Why doesn't this context class specifically "extend" or "implement" the generic State base class/interface?

  • OpenAL device, buffer and context relationship

    - by Markus
    I'm trying to create an object oriented model to wrap OpenAL and have a little problem understanding the devices, buffers and contexts. From what I can see in the Programmer's Guide, there are multiple devices, each of which can have multiple contexts as well as multiple buffers. Each context has a listener, and the alListener*() functions all operate on the listener of the active context. (Meaning that I have to make another context active first if I wanted to change it's listener, if I got that right.) So far, so good. What irritates me though is that I need to pass a device to the alcCreateContext() function, but none to alGenBuffers(). How does this work then? When I open multiple devices, on which device are the buffers created? Are the buffers shared between all devices? What happens to the buffers if I close all open devices? (Or is there something I missed?)

  • Django: automatically import MEDIA_URL in context

    - by pistacchio
    Hi, like exposed here, one can set a MEDIA_URL in settings.py (for example i'm pointing to Amazon S3) and serve the files in the view via {{ MEDIA_URL }}. Since MEDIA_URL is not automatically in the context, one have to manually add it to the context, so, for example, the following works: #views.py from django.shortcuts import render_to_response from django.template import RequestContext def test(request): return render_to_response('test.html', {}, context_instance=RequestContext(request)) This means that in each view.py file i have to add from django.template import RequestContext and in each response i have to explicitly specify context_instance=RequestContext(request). Is there a way to automatically (DRY) add MEDIA_URL to the default context? Thanks in advance.
