• Logitech C510 HD Webcam related question

  - by Ashfame

  I am going to buy Logitech C510 HD webcam and I just checked on other questions here on AskUbuntu that it works out of the box with cheese. My question is can it be limited in any functionality that I would like to do with it? I would like it to be used with everything - Skype, Gtalk video chat, Facebook, Youtube etc I would like the ability to record or do a video call in lesser resolution video (its a 720p one). Also since I read that I should have a Core2Duo 2.2Ghz for 720p but I have a 2.0Ghz one, would it be possible for me to first record it and then encode it after recording if my processor really start giving issue when doing on-the-fly encoding? Anything else that I should consider? I also have a ATI HD 4850 512MB card, if it can help in encoding on-the-fly or is there a chance that my graphics card alone can handle it and those specs were just for a system without a graphics card? I believe so. Also, I got no worries in dealing with console, if I have to do some of the things above in terminal. Other possible significant details: I have a dual screen setup 29" (1360X768) & 22" (1680X1050) which might be using some good power from GPU and I have 2GB DDR2 800Mhz RAM.

• Can't get samba to see other PCs in Kubuntu 10.04 (Lucid)

  - by MaurizioPz

  I'm new to networking. I'm trying to share a folder between to computers (both have kubuntu 10.04 installed). I'm able to share a folder with samba and can see that folder through samba on the same computer. But if I try to go on the other PC I can't see the first one. Both PCs are on the "workgroup" workgroup. I've tried disabling the firewall with firestarter can somebody help me? thanks

• New computer - AMD with which mobo? [closed]

  - by RhZ

  I need to buy new computers for the office, all running ubuntu 10.04 or 11.10, whichever works. I am looking at a asus mobo with the AMD870 northbridge and 850 sounthbridge. Can anyone tell me if that is buggy or not? And with maybe an Athlon II X4 640 processor. At home I am running an asus mobo with AMD880/SB850 at home, which is good, although the on board ATI video card was buggy, I put a nvida card in as well and its great now. But for the office I want to save cost, don't need a kick-ill system. Still, I need the machines to be fast and look good, don't want to skimp on performance. Can anyone provide me with some advice about this? I will buy a custom machine, not from one of the big manufacturers. Thanks! :-)

• What were the typical price range for a development kit?

  - by Vaughan Hilts

  A lot of these things are usually behind NDAs and tricky to gauge. Is there any information and ranges on how much these thing costs? For example, the PS1 had the "Net Yaroze", which according to Wikipedia was: "For about $750 USD, the Net Yaroze (DTL-H300x) package would contain a special black-colored debugging PlayStation unit with documentation, software, and no regional lockout." So, what were the prices of some game development kits? P.S: This might make a good community wiki

• Are EC2 security group changes effective immediately for running instances?

  - by Jonik

  I have an EC2 instance running, and it belongs to a security group. If I add a new allowed connection to that security group through AWS Management Console, should that change be effective immediately? Or perhaps only after restart of the instance? In my case, I'm trying to allow access to PostgreSQL's default port (tcp 5432 5432 0.0.0.0/0), and I'm not sure if it's the EC2 firewall or PostgreSQL's settings that are refusing the connection.

• Switching between Discrete and Integrated GPUs

  - by void-pointer

  Hello everyone, I develop CUDA applications on my Alienware M17x portable back-breaker, which has two discrete GTX 285M GPUs and one integrated GeForce 9400M GPU. I can currently switch between them using NVIDIA's software, but I would like the ability to do so within my applications for purposes of benchmarking and general convenience. Apparently this requires the "NDA version" of NVIDIA's Driver API, which I know not how to obtain. Would using this API be the only way to accomplish what I seek, and if so, how would I obtain it? A solution using Windows APIs would also be acceptable, though less preferable to one which would leverage a cross-platform API. I have created a similar thread concerning the matter on NVIDIA's forum, which is down at the time of this writing. Thanks for reading my question; it is much appreciated!

• Trying to update Asus BIOS: FreeDOS crashes

  - by ZekeDroid

  My UX31 zenbook is experiencing some weird shutdown behavior when the battery drops below 50% and the internet seems to agree that updating the BIOS is a good step forward since there were issue with the kernel before. I downloaded both the correct BIOS file and the windows 7 utility tool and now need to boot FreeDOS to run, however, I've tried every method out there and they all fail (or so I think): Using unetbootin's FreeDOS 1.0 image I get to an error saying it couldn't run drivers then I get to a command line on disk A:. I assumed a dead end. Using unetbootin but with the FreeDOS 1.1 version image downloaded directly: get an error of "bad or missing command interpreter". I looked online and the solutions didn't work either. So, is there an alternative to FreeDOS or to installing a BIOS that I could use?

• Questions before I revamp my rendering engine to use shaders (GLSL)

  - by stephelton

  I've written a fairly robust rendering engine using OpenGL ES 1.1 (fixed-function.) I've been looking into revamping the engine to use OpenGL ES 2.0, which necessitates that I use shaders. I've been absorbing information all day long and still have some questions. Firstly, lighting. The fixed-function pipeline is guaranteed to have at least 8 lights available. My current engine finds lights that are "close" to the primitives being drawn and enables them; I don't know how many lights are going to be enabled until I draw a given model. Nothing is dynamically allocated in GLSL, so I have to define in a shader some number of lights to be used, right? So if I want to stick with 8, should I write my general purpose shader to have 8 lights and then use uniforms to tell it how many / which lights to use? Which brings me to another question: should I be concerned with the amount of data I'm allocating in a shader? Recent video cards have hundreds of "stream processors." If I've got a fragment shader being used on some number of fragments in a given triangle, I assume they must each have their own stack to work on. Are read-only variables copied here, or read when needed? My initial goal is to rework my code so that it is virtually identical to the current implementation. What I have in mind is to create my own matrix stack so that I can implement something along the lines of push/popMatrix and apply all my translations, rotations, and scales to this matrix, then provide the matrix to the vertex shader so that it can make very quick vertex translations. Is this approach sound? Edit: My original intention was to ask if there was a tutorial that would explain the bare minimum necessary to jump from fixed-function to using shaders. Thanks!

• Creating your own computer! [closed]

  - by AntonioCS

  I recently found this article on a guy that built his own computer. It's just a bunch of wire (as far as I can tell any way) and I was just wondering what would I have to learn/read/do to make such a thing (or at least to have a really basic understanding of what he did). He also made his own operating system, which I find really impressive. I know it will take a while and I am in no hurry. Note: I am a web programmer and also have done some desktop apps (a few years ago).

• SSH: Port Forwarding, Firewalls, & Plesk

  - by Kian Mayne

  I edited my SSH configuration to accept connections on Port 213, as it was one of the few ports that my work firewall allows through. I then restarted sshd and everything was going well. I tested the ssh server locally, and checked the sshd service was listening on port 213; however, I still cannot get it to work outside of localhost. PuTTY gives a connection refused message, and some of the sites that allow check of ports I tried said the port was closed. To me, this is either firewall or port forwarding. But I've already added inbound and outbound exceptions for it. Is this a problem with my server host, or is there something I've missed? My full SSH config file, as requested: # $OpenBSD: sshd_config,v 1.73 2005/12/06 22:38:28 reyk Exp $ # This is the sshd server system-wide configuration file.

• Install a i386 printer driver into an amd64 distribution or how can I find a good printer based on features?

  - by Yanick Rochon

  Hi, I just bought a Lexmark Interpret S408 all-in-one printer. The box said that it supported Ubuntu 8.04, but I told myself it should work with Lucid... well no. The only driver I have found is for i386 while I have a amd64 image installed; the architecture is incompatible. So, the quesiton is : Is it possible to install that driver anyway, somehow? Or do I need to take that printer back to the store and buy another one? If the latter is the only alternative, I need a printer that has wireless connection capability can do color printing is of good price (less than $200 CAD) Thank you for your answers, help, and tips. ** UPDATE ** The driver was given in the form of deb package (for Debian distributions) and I managed to extract the actual deb package driver out of the install program. I ran sudo dpkg -i --force-all lexmark-inkjet-09-driver-1.5-1.i386.deb and the driver installed, and I was able to print something out. But that pretty much ends there; I cannot access anymore of the printer settings, etc. (i.g. scanner, fax, wifi settings, etc.) I should suffice for now as I'm satisfied with the printer's features (and size, and prince), but if I could have a full-linux-supported printer like that one, I would return this one in exchange for the other.

  hi guys, I got a gift from a friend, 2 readers for RFID, and some cards (from a Chinese company called daily rfid), the kind of work, because it comes with some demo software written in Delphi, that reads the id of the card (myfare compatible, ISO14443A ) but the problem is that if I try to use the demo to write to them, it doesnt seem to work, it have another demo written in c#, (compiled and executable from /bin/debug, the DL600DemoCSharp.exe), the software opens, but when click on connect, I get this error Unhanded exception.. unable to load DLL 'BasicB.DLL' so I load the dll on windows/system32, but when I try regsvr32 BasicB.dll I get, error the module "BasicB.dll" was loaded but hte entry-point DllRegisterServer was not found. Make sure that "BasicB.dll" is a valid DLL or OCX file and then try again have written to the company but no response, I program in objective C, so I kind of understand c#, but how to make this cards work? - shall I continue with the delphi, and try to write to them with it - or with c# - either way I would have to write the code to read write to them,, or is there any software to work with this modules?? thanks a lot!

• Loading wordpress admin page prevents and blocks further requests

  - by Auxiliary

  I've installed a Wordpress site on a host (actually I moved it from localhost). The site loads and works perfectly, however if I log in with Admin, the admin page doesn't completely load and all further requests to the server are blocked for about 10 or 15 minutes. I can't even ping to the site. Where could this problem be from? Is it firewall related or...? Any help or idea is greatly appreciated.

• Wake On LAN on request

  Hi, I have a small home network with the router capable of running OpenWRT, is there some utility or firewall rule, which can be used to Wake On LAN on request. What I think - if I want to access my media centre (using for example SSH or HTTP) and it is suspended, is it possible to catch the ICMP packet (saying the machine is offline) and send the WOL packet to wakeup the machine and resend the SSH or HTTP request? Thanks

• Fake RAID (dmraid) not seeing new SATA drives

  - by rausch

  I have three drives in my machine, one SSD with 32GB and two 1TB drives, attached to an Intel 82801JI (ICH10) SATA AHCI Controller. The problem is, that I can access only one of the 1TB drives when the other one is not plugged in. When it is plugged in I see the drives as sda and sdb, but there seem to be no partitions. Looking at these drives with cfdisk, the partitions are there, though. Both of the 1TB drives are carrying a partition, being part of a software RAID1, created with mdadm. Before I threw the SSD into the mix, the other two have been working fine. Any hints?

• Does the Virtual PC XP Mode need safety measures?

  Does the Virtual PC XP-Mode (or any other virtualized mode) require safety measures, such as antivirus or a firewall? I'm just wondering if the XP-Mode would be a large security loophole, since it's so much more integrated into Windows 7. Actually I'm wondering the same for Portable Ubuntu, are their any safety measures I should undertake, so that I don't open a backdoor on my computer.
