• How is Logitech C510 HD Webcam

  - 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. Jorge's response also confirm this and I feel confident buying it now. 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. Also this may sound lame but I need to know whether I could record or do a video call in lesser resolution video (its a 720p one)? Edit: Ported part of this question to another question to make it more specific.

• Redirect from the main page on multilanguage site

  - by Pluto

  I've decided to start developing multilingual web site. Now I'm thinking about the structure. The idea is to use a simple algorithm to find out what language is most interesting to the visitor when he makes his first visit to the root page, and then forward him to the corresponding address, for example, http://example.com/en/ for English-speaking audience and http://example.com/ru/ for Russians. The question is, how search engines react on such redirect? If this approach does not take away site's reputation, which redirects should I choose: 301 or 302? I would be very grateful for the reasoned response.

• Fiddler - A useful free tool for checking Web Services (and web site) traffic

  - by TATWORTH

  Recently I had reason to be very glad that I had Fiddler. I was able to record some web service traffic and identify a problem as Fiddler can record both the call to a web service and response from the web service. By seeing the actual data traffic I was able to resolve a problem found in testing in less time than it has taken me to write this blog entry! This tool is also useful for studying general web site traffic. Fiddler is available from http://www.fiddler2.com/fiddler2/ There are training videos available on the above site.

• No HDD shows up during install 12.04 on Lenovo U410

  - by varunthacker

  I tried installing Ubuntu 12.04 on my Lenovo U410 laptop. When I launch installation no partitions shows up. The U410 has 2 HDDs. 32 GB SSD on /dev/sda and a 500 HDD on /dev/sdb Ideally I would like to install Ubuntu on the 32GB SSD and keep Windows on the 500 GB one and not use the Intel Smart Response Technolog. I'm ok with flashing my drive and starting from scratch with this. Or do you'll have any better suggestions on how to go about partitioning my drive and how to do it?

• Why do we use networking libraries instead of plain NSURLRequests and NSURLConnection ?

  - by Amogh Talpallikar

  in iOS development, I have often seen people creating a networking module to interact with their APIs. This module generally sits on top of a networking framework like MKNetWorkKit or AFNetWorking. In most of the cases, It's all about sending GET,POST request and parsing the response which is in most cases JSON. What extra practical benefits that these libraries provide that an iOS developer should be leveraging which the plain Cocoa Networking APIs lack ? I can understand RESTKit as one exception where it takes care of the conversion of JSON to native objects and also interfaces with Core Data but what about others ?

• Why won't Remmina connect to Windows 7 Remote Desktop?

  - by rfc1484

  I'm using Ubuntu and I'm trying to connect to another machine in a different network using remote desktop. In Windows7 I have made the following in order to activate remote desktop: I've gone to computer - properties - remote settings I've selected the option: "Allow connections from computers running any version of Remote Desktop I've opened "Windows Firewall with Advanced Security" In inbound rules I've enabled the rules for remote desktop (public and domain) I have also installed Remmina in the Ubuntu machine. For configuring it I did the following steps: Selected the RDP protocol In the server input I have written the Windows machine public IP. In username / password I have typed my login credentials (the same as my Windows admin account) But when I try to connect I get this error message: "Unable to connect to RDP server 89.130.251.160" If I ping my Windows7 machine, I have a correct response. Any suggestions?

• Learning to program on punchcards

  - by Plutor

  I'd like to try programming with punch cards once in my life. How can I do this? I'm in my 30s, and grew up entirely in the PC era, programming on computers with screens and keyboards. I want to experience the way my father and grandfather used to work. I imagine the hardware (and probably the cards themselves) are no longer manufactured. Are there any universities or museums with functioning punch card readers anymore? I'm in Boston, but I'm willing to travel to do this. I asked MetaFilter, and I got some mixed answers (along with a lot of "no, don't do this" nay-saying). I did get a pointer to the Retro-Computing Society Of Rhode Island, but I haven't received a response to my email to them yet.

• How can I print-screen just one window and not my entire desktop?

  - by Michael Durrant

  I could swear I've always been able to do alt-printscreen to get 'just that window' but right now I am getting my entire desktop. Any idea why this would be or what I can do to get my ability to do small window screen shots? I've tried a lot of combination with the ctrl, alt, shift and print-screen keys but no luck, nothing happens in response. One option: shift-ctrl print-screen lets me do a selection using a cross hair to size out the screen capture but I don't know where this gets saved. I'm not being given the choice and it's not in Desktop or Pictures. I use an external keyboard, but I've tried using the laptop's own keyboard and no difference. I am running Ubuntu 12.04 and the laptop is a Samsung Ultrabook 900 Update: I rebooted and it "fixed" it - for now. However this is not the first time I've seen this so I'm still curious as to why it happens, what I can do to fix w/o reboot and if other share the same problem.

• What Java class should I use to represent a Vector?

  - by user8363

  Does Java have a built-in Vector class suitable for handling collision detection / response? It should have methods like subtract(Vector v), normalize(), dotProduct(Vector v), ... It seems logical to use java.awt.Rectangle and java.awt.Polygon to calculate collisions. Would I be right to use these classes for this purpose? I understand collision detection; I'm only wondering what approach to it is idiomatic in Java. I'm new to the language and to application development in general.

• How To Purchase An MSDN License In India [closed]

  - by Subhash

  I need to purchase a single license for Visual Studio Professional with MSDN. The MSDN buy site (http://msdn.microsoft.com/en-us/subscriptions/bb841434.aspx) does not allow purchases from India. It directs Indians to purchase from resellers. I contacted Microsoft and they sent me a link to a list of resellers http://www.microsoft.com/india/originalsoftware/business/retailStore1.aspx Many of these resellers do not even have a website. Many of them do not exist at the addresses mentioned (they have moved). Microsoft support personnel also seem very cagey about releasing any information. They do not even read the mail. They simply resend their canned response with the same link. There are many resellers (not mentioned in the microsoft page) who are selling MSDN subscriptions. Are they legitimate? Here is one site: http://www.aditicomputers.com/developers-software/microsoft-visual-studio-2010-professional-with-msdn.aspx How do Indian developers purchase MSDN?

• "Unclutter" units in RTS game

  - by TravisG

  For intentional reasons, certain units in the game I'm currently programming don't have any collision detection and response among each other. This enables them to clutter right on top of each other. This is a wanted behavior, since there will be situations in the game when the player does want them to stack like that. However, I want to make the process of uncluttering them easy for the player, so that they just have to press a hotkey or click some button on the screen and have the units disperse just enough so it's easy to select a group of them with the mouse (if they stand on top of each other one mouseclick selects all units). How could I do this without running a brute force N^2 nearest neighbor search on all units?

• Problems using PHP on a Plesk Windows dedicated server

  - by wpsmdouble

  I'm having a few issues with my dedicated Windows server that has a Plesk panel: 1.) I can't send e-mail via PHP's mail() function, it always returns the following error: SMTP server response: 550 Requested action not taken: mailbox unavailable or not local Which setting should I alter in order to enable sending mail? 2.) The exec() and passthru() PHP functions don't work; their outputs are blank even when I try to run simple commands such as dir. Is there an option that I can toggle in the control panel to enable this functionality?

• How would you answer this job-interview question?

  - by ahmed

  One of the five people who interviewed me asked a question that resulted in an hour-long discussion: "Explain how you would develop a frequency-sorted list of the ten thousand most-used words in the English language." My initial response was to assail the assumptions underlying the problem. Language is a fluid thing, I argued. It changes in real time. Vocabulary and usage patterns shift day-to-day. To develop a list of words and their frequencies means taking a snapshot of a moving target. Whatever snapshot you take today isn't going to look like the snapshot you take tomorrow or even five minutes from now. Thanking you advance for your answers and consideration.

• Collision: Vector class (java)

  - by user8363

  When handling collision detection / response and you need a Vector class, do you need to create that class yourself or is there a java class you can use? A vector class should have methods like: subtract(Vector v), normalize(), dotProduct(Vector v), ... At the moment it seems logical to use classes like java.awt.Rectangle and java.awt.Polygon to calculate collisions. Would I be right to use these classes for this purpose? My question is not about how to implement collision detection, I know how that works. However I'm wondering what would be a correct and clean way to implement it in java since I'm fairly new to the language and to application development in general.

• Magento not responding to payment gateway notifications fast enough or at all?

  - by robgt

  Some of our customers are getting to the confirmation of payment step in purchasing from our Magento store, and then they are getting a timeout error, where the SagePay payment gateway is trying to contact our server to tell it that a payment was successful (or not…) but it cannot contact our server, or cannot get a response from our server in a timely manner, and then the payment/order is being cancelled. I've raised this question to my hosting company, but all they told me was: "This is down to the way the software is configured on your server" This is currently a Magento 1.4.0.1 standard installation as far as payment gateways are concerned. What on earth could this statement mean? Is there some configuration that I need to do to make Magento listen to these requests and respond properly?

• Alternatives to JS in the browser: your experience [closed]

  - by Andrea

  In these days there are many projects whose aim is to bring new languages to the browser by compiling them to JavaScript. Among the others one can mention ClojureScript, CoffeScript, Dart, haXe, Emscripten, Amber Smalltalk. I understand that in part the response to this answer depends on the particular project. But, anyway: Have you tried any of them? Are these tentatives suitable for production sites? Should I want to try one of those, what are the downsides I should carefully evaluate? By the way, I expect the answer to be slightly misleading for CoffeeScript, since its semantics is very close to that of JavaScript, so I guess it should be easier to make it work seamlessly with the existing JavaScript ecosystem.

• How does thumbnail preview in Ubuntu differ from that of Windows? [closed]

  - by Forbidden Overseer

  Possible Duplicate: How does Ubuntu know what file type a file without extension is I thought this question might get a better response in AskUbuntu, as it seems to have more to do with Ubuntu than Windows at a glance. Let's say I have a foo.mkv file. Thumbnail previews work in both Windows 7 and Ubuntu. When I change the filename to anything random like foo.bar or when I remove the extension itself (making it just foo), Nautilus shows thumbnails normally like if it can recognize what type of files they are - without looking at file extension. This however, doesn't happen in Windows 7. Windows starts asking me things like which application I want to use to open that file as soon as I remove file extension (forget thumbnails...) etc. So, How does this thumbnail preview work in Windows 7 and Ubuntu? What makes Ubuntu recognize files "out of the box" unlike Windows 7?

• Do navigation menu links negatively impact SEO for pages' content?

  - by Rodolfo

  I've always had my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

• Maya and Game Engines (i.e. Environment Testing)

  - by DiscreteGenius

  What does it mean if I'm designing an environment and I want to test it in the game engine, to see what its like to "run" [or fly] around my environment? I heard an instructor say that exact thing in a Maya training video and I'd like to know more about "How Game Engines and Maya are related to each other." He stated this would be done to see how things look in "size" (e.g. I assume he meant: 'How big is the cathedral, bridge, wall, building, etc.'). I've tried to research such information but it's too complicated, and detailed. I just want a simplistic response to my query. Thanks to everyone willing to help and not criticize my question.

• The input doesn't recognize that I release the key?

  - by joapet99

  I'm creating a window (JOptionPane), in response to a collision. However, if the player is holding a key down when the window pops up, the input doesn't trigger a key release when the key is released. I don't think you can just check it with a isRelease function in the input, since the input is kind of corrupt. Can you help me? The way I check if the key is down: if(input.isKeyDown(Input.KEY_A)&& TestLevel.isFighting == false){ if(owner.canMoveLeft){ position.x -= speed * delta; } } I am not handling the key release by myself, but if I check if the key is down it should work. But it doesn't.
