• External microphone not working

  - by haireefairee

  gnome-volume-control does not recognise external hardware. My headphones work nonetheless, but an external microphone does not. External microphones used to work, but at times were temperamental - I would have to login or logout with or without microphone plugged in. I am running Ubuntu 10.04 LTS (Lucid Lynx) on an mSi U100 wind notebook with one Intel soundcard and trying to use a jack microphone which has worked previously. USB microphones have also been problematic. I have done the basics: Installed upgrades. Checked nothing is muted. Looked for the device on gnome-volume-control. Tried using a different microphone that works on a friends computer. Tested my microphone works when using a different computer. Checked my soundcard can be seen (cat /proc/asound/cards). I have done more complicated things: I have tried playing around with settings in alsamixer. Nothing is muted. I can adjust "mic" and "internal mic" regardless of whether an external microphone is plugged in. I have the choice of input source from "mic", "front mic", "line" and "CD". I've played around changing this and it hasn't helped. I only have one CAPTURE option. In gnome-sound-recorder I have the choice of line, microphone 1 and microphone 2. I have played around changing this option. None of these pick up sound from the external microphone. Microphone 2 is the microphone on my laptop which is bad quality. In gnome-sound-recorder I have the choice of different profiles, and changing this has not helped either. I have looked at gstreamer-properties but none of that seemed helpful. I don't know if there a way to check if these external devices are being picked up. I would like to make an external microphone work. Please help!

• How to stop Python program execution in IDLE

  - by joaoc

  I have a python script that uses plt.show() as it's last instruction. When it runs IDLE just hangs after the last instruction. I get the image but I don't get the prompt back. On other scripts I typically use ctrl-c to break the program (sometimes doesn't work immediately) but how do I get the prompt back with the plt.show()? Ctrl-c doesn't work... Are there other ways to stop the program? This is IDLE on Windows, if it makes any difference.

• Wubi doens't work anymore - shows 'No wubildr' error

  - by Joe

  Basics: HP Mini 311 Ubuntu netbook edition 10.04 (installed via Wubi) Symptoms: I load to Windows Boot Manager as usual. Options are Windows 7 and Ubuntu Netbook, like usual. Selecting Windows 7 does as it should. Loading Ubuntu Netbook, though, does not take me to the usual screen where it lets me select versions of Ubuntu (sorry for bad wording, not sure what the real name is called; it's where you select from about 6 items; I always picked the first due to lack of knowledge without issue). Instead it flashes an error in white on a black screen then restarts very quickly. It took me a few restarts, but here is the error: Try (hd0,0): NTSF5 No wubildr Try (hd0,1): NTSF5: Situation: I have no clue what caused it. The only thing I did last night on Ubuntu was install Skype, but the mic didn't work instantly so I got lazy and switched to Windows 7 and used Skype on there. When I tried to switch back to Ubuntu it began this. (There may be something I forget... it was 5 in the morning). There were no recent updates that I remember. No weird activity. Just... random. Help please?

• Coding in large chunks ... Code verification skills

  - by Andrew

  As a follow up to my prev question: What is the best aproach for coding in a slow compilation environment To recap: I am stuck with a large software system with which a TDD ideology of "test often" does not work. And to make it even worse the features like pre-compiled headers/multi-threaded compilation/incremental linking, etc is not available to me - hence I think that the best way out would be to add the extensive logging into the system and to start "coding in large chunks", which I understand as code for a two-three hours first (as opposed to 15-20 mins in TDD) - thoroughly eyeball the code for a 15 minutes and only after all that do the compilation and run the tests. As I have been doing TDD for a quite a while, my code eyeballing / code verification skills got rusty (you don't really need this that much if you can quickly verify what you've done in 5 seconds by running a test or two) - so I am after a recommendations on how to learn these source code verification/error spotting skills again. I know I was able to do that easily some 5-10 years ago when I din't have much support from the compiler/unit testing tools I had until recently, thus there should be a way to get back to the basics.

• Logoff button IIS6 ASP.NET Basic Authentication

  - by willyconnor

  I have a requirement for an explicit logout button for users in a ASP.NET web app. I am using IIS6 with Basic Authentication (SSL). I can redirect to another web page but the browser keeps the session alive. I have googled around and found a way to do it by enabling an active x control to communicate with IIS and kill the session. I am in a restricted environment that does not allow forms authentication and active x controls are not forbidden as well. Has anyone else had this requirement and how have you handled it? Okay that is what I was afraid of. I have seen similar answers on the net and I was hoping someone would have a way of doing it. Thanks for your time though. I guess I can use javascript to prevent the back button like the history.back()

• Upgrading to IIS7 stopped Firefox from receiving cookies?

  - by Ted Spence

  Our website has been using IIS6 for a long time. We test on IE8, Firefox, and Chrome. All browsers worked fine. We recently did an upgrade to IIS7, and Chrome and IE8 continue to work normally, but Firefox appears to be unable to get the ASP session cookie. As a result, when our code checks the Session[] object, we see nothing, we think the user has logged out, and the site resets your session. Does anyone know why upgrading to IIS7 would cause this behavior in Firefox? We've: 1) Reverted our application pool back to classic mode (no change); 2) Added a dummy value in the Global.asax object (no change); and 3) changed the web.config file from "authentication cookieless=autodetect" to "cookieless=usercookie" and back (no change).

• How to stop SWF inside of a jQuery UI tab from reloading

  - by Raul Agrait

  I have a SWF movie inside of a jQuery UI tab, and the problem I'm having is that the SWF gets reloaded everytime I click away from the tab, onto another tab, and then click back. I can inspect the DOM and see that the div containing the SWF is still in the DOM when I click away, so I don't know why this it seems to reload it when I click back to the tab. I added the following CSS rules to try to prevent the display being set to: none, but the Flash movie is still reloading: .ui-tabs .ui-tabs-hide { display: block !important; position: absolute; left: -10000px; }

• Communicating with the PC via USB connection in Android

  - by Danny Singh

  I'm fairly new to android programming and need some information for a 4th year forensics course project. Basically I am trying to create a suite of tools for live analysis of an android phone. I know how to get the information I need on the phone, but I was wondering if there was a way to communicate that information back to the PC? I want to be able to run a program from a PC, which, when the phone is docked, will allow the user to access information about the phone (ie currently running services/processes, bluetooth/wifi connections, etc). I have a bunch of methods that will run on the phone and get all the information, but I want to be able to call those methods from the PC, execute on the phone, then have the information sent back to the PC to display to the user instead of just displaying it on the phone. This is to leave as small a footprint on the phone as possible. Thanks a lot.

• Is it possible for beginner to learn and develop an application in rails in 4 months?

  - by Parth

  I want to develop a web application or a website using rails. My current knowledge includes 1. HTML 2. CSS 3. C 4. Java And I am currently going through 5th chapter of the well grounded rubyist book by David A. Thomas. I came to know that learning ruby is beneficial for good knowledge of rails. So currently I am going through the basics of ruby. And learning rails in parallel. I want to know if in this scenario is it practically feasible to understand rails and develop an application/website in it within the time frame of 4 months. I need to develop an application which have atleast 3 complexity (complex functionality). Any ideas of good application for rails beginners is welcomed. But the application should be large or if it is small than it should have some complexity. Time is a constraint for me. I would have to develop application for college work but rails technology is my choice as I want to learn it.

• HttpWebRequest.GetResponse() - what specific status codes cause an exception to be thrown?

  - by H. Morrow

  I've hunted around for some definitive documentation on this but haven't had much luck finding any. Basically - the question is - for which HTTP Status codes coming back from the server will HttpWebRequest.GetResponse() generate a WebException after doing something like say, a POST? Specifically - will it generate a WebException for anything other than status 200 OK? Or will it only generate a WebException for say, 400, 404, and 500 (for the sake of argument). I want to know since, the server I'm communicating with defines anything other than HTTP 200 OK coming back as an error condition - and the key is, can I rely on a WebException being generated for anything other than 200? (I've currently written my code so that it'll actually check the return status code everytime to ensure it's 200 OK and if it's not, take appropriate action - but it's alot of duplication between that, and the catch block for a WebException, and I'm hoping to clean it up...) Any relevant links to documentation would be most appreciated. Thanks!

• Opencv python and webcam

  - by Neil Benn

  Hello, I'm working with OpenCV on a beagleboard with ubuntu and OpenCV 1.1 interfaced via Python. I'm trying to set something up to capture a feed from a UVC compatible webcam (logitech C250). I have tested the webcam with luvcview and it works but only if I set the input format to YUV. If I run it in 'normal' mode I am getting back jpeg frames and something - somewhere is not happy! I'm trying to connect with the webcam in OpenCV as I want to get the image back from the webcam and run some analysis on it. As I have a limited device this seems to be the most efficient way of doing it - however I need to instruct the capturing system to capture in YUV and not jpeg. Is there a way of doing this (for example luvcview allow me to enter luvcview -f YUVY)? Cheers, Neil

• C# Stream Reader adding \n to XML

  - by Terry

  I use the StreamReader class to obtain XML for my GeoCoding process from Google. StreamReader srGeoCode = new StreamReader(WebRequest.Create(Url).GetResponse().GetResponseStream()); String GeoCodeXml = srGeoCode.ReadToEnd(); XmlDocument XmlDoc = new XmlDocument(); GeoCode oGeoCode = new GeoCode(); XmlDoc.Load(GeoCodeXml); I get XML back but it adds \n and other extras to the XML <?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n<kml xmlns=\"http://earth.google.com/kml/2.0\"><Response>\n <name> I have the same code in VB and it does not do this. I can successfully GeoCode my information using the VB version of this console app. Is there a reason the C# version adds this extra data to the XML that I retrieve back? I am trying my best to convert everything over to C#. I enjoy coding in it over VB.

• Visual Studio 2008 Unexpected Error on Project Checkout with VSS 2005

  - by Cyberherbalist

  I've encountered an odd misbehavior of VS 2008's integration with Visual Source Safe 2005. Situation occurs when I fire up VS2008 when a project is checked out to someone else, and later they check the project back in, while I still hold the VS2008 open. If I at that time add a new item, VS2008 tells me that my action has caused a check out of the project and a new version has been loaded from source control. Fair enough, but thereafter I get an error dialog stating "Visual Studio has encountered an unexpected error" with OK at every subsequent action, such as save file and search text, making it almost unusable. This is overcome by closing VS (which pops the error dialog once more) and restarting. Is there some kind of fix or workaround to this (besides the obvious ones: "don't try to check out the project when it's checked out to someone else", or "get latest version if you think the other person may have checked the project back in")?

• Redirect to show ModelAndView from another Controller - (Spring 3 MVC, Hibernate 3)???

  - by Mimi

  How exactly can I trigger display of a model and view from another model and view’s controller? [B][COLOR="Blue"]HTTP Request View -- HttpRequestController POST - new HttpResponse POJO and a string of the POJO in XML as an Http Response msg to be sent back to the Requestor --[/COLOR][/B] [B][COLOR="Red"][/COLOR][/B] I have HttpRequestController() to handle a POST message with data from an input Form and populated an HttpRequest POJO with it. An HttpResponse POJO is composed and persisted along with the HttpRequest to a Db. I made this HttResponse POJO an XML string as the @Responsebody to be sent back by the HttpRequestController() (as an actual HTTP Response message with header and body) and I want to present this HttpResponse POJO in a View. I tried different things, none worked and I could not find a similar example anywhere.

• Is it possible to interop with Thunderbird using C#?

  - by Jurily

  Here's the latest hurdle in my ongoing quest to automate my job: All email in the company goes through 4 different email adresses, switching randomly back and forth (with a note attached in the global share: please set "keep email on server") All logic related to email is contained in a nice big Thunderbird profile, which gets copied back and forth to new machines; this includes sorting invoices into 5 different "folders", the list of VIP adresses to send notifications, and the VIP level of those customers I only need the contents of those folders (the attachments, anyway) The question: is there a way to ask Thunderbird for those attachments and lists from C#? Alternatively, can Outlook be set up to synchronize with Thunderbird? Where do I start reading? Ditching Thunderbird is not an option right now, I need to keep up with changes to the VIP list. P.S. I will set up a real email server right after Monkey saves me enough time to convince people about it.

• The Future of Life Assurance Conference Recap

  - by [email protected]

  I recently wrote about the Life Insurance Conference held in Washington, DC last month. This week I was both an attendee and guest speaker the 13th Annual Future of Life Assurance Conference held at The Guoman Tower in London, UK. It's amazing that these two conferences were held on opposition sides of the Atlantic Ocean and addressed many of the same session topics and themes. Insurance is certainly a global industry! This year's conference was attended by many of the leading carriers and CEOs in the UK and across Europe.The sessions included a strong lineup of keynote speakers and panel discussions from carriers such as Legal & General, Skandia, Aviva, Standard Life, Friends Provident, LV=, Zurich UK, Barclays and Scottish Life. Sessions topics addressed a variety of business and regulatory issues including: Ensuring a profitable future Key priorities in regulation The future of advice The impact of the RDR on distribution Bancassurance Gaining control of the customer relationship Revitalizing product offerings In addition, Oracle speakers (Glenn Lottering and myself) led specific sessions on gearing up for Solvency II and speeding product development through adaptive rules-based systems. The main themes that played throughout many of the sessions included: change is here, focusing on customers, the current economic crisis has been challenging and the industry needs to get back to the basics and simplify - simplify - simplify. Additionally, it is clear that the UK Life & Pension markets will be going through some major changes as new RDR regulation related to advisor fees and commission and automatic enrollment are rolled out in 2012 Roger A.Soppe, CLU, LUTCF, is the Senior Director of Insurance Strategy, Oracle Insurance.

• C++: Dependency injection, circular dependency and callbacks

  - by Jonathan

  Consider the (highly simplified) following case: class Dispatcher { public: receive() {/*implementation*/}; // callback } class CommInterface { public: send() = 0; // call } class CommA : public CommInterface { public: send() {/*implementation*/}; } Various classes in the system send messages via the dispatcher. The dispatcher uses a comm to send. Once an answer is returned, the comm relays it back to the dispatcher which dispatches it back to the appropriate original sender. Comm is polymorphic and which implementation to choose can be read from a settings file. Dispatcher has a dependency on the comm in order to send. Comm has a dependency on dispatcher in order to callback. Therefor there's a circular dependency here and I can't seem to implement the dependency injection principle (even after encountering this nice blog post).

• StreamReader ReadToEnd() after HttpWebRequest EndGetResponse() - most scalable?

  - by frankadelic

  I am calling a RESTful web service in the back-end of some ASP.NET pages. I am using ASP.NET asynchronous pages, so under the hood I am using the methods: HttpWebRequest BeginGetResponse() and HttpWebRequest EndGetResponse() The response string in my case is always a JSON string. I use the following code to read the entire string: using (StreamReader sr = new StreamReader(myHttpWebResponse.GetResponseStream())) { myObject.JSONData = sr.ReadToEnd(); } Is this method OK in terms of scalability? I have seen other code samples that instead retrieve the response data in blocks using Read(). My primary goal is scalability, so this back-end call can be made across many concurrent page hits. Thanks, Frank

• SQL Server for the Oracle DBA Links

  - by BuckWoody

  I do a presentation (and a class) called "SQL Server for the Oracle DBA". It's a non-marketing overview that gives you the basics of working with SQL Server if you're already familiar wtih how Oracle works. This class and these links DO NOT help you with "Why should I use Oracle/SQL Server instead of Oracle/SQL Server" - I'll assume you're already there, and if not, there are LOTS of sites to help you make that decision. Although these links might contain slight marketing slants (I don't control them) I've tried to get the best links I can. Feel free to comment here to add more/better links. As such, these aren't links that help you work with Oracle - they are links to help you work with SQL Server. Some of them contain more information than you actually need, others don't have near enough. Taken together (and with the class) you're able to get done what you need to do.

• QTableWidget signal cellChanged(): distinguish between user input and chage by routines

  - by crabman

  i am using PyQt but my question is a general Qt one: I have a QTableWidget that is set up by the function updateTable. It writes the data from DATASET to the table when it is called. Unfortunately this causes my QTableWidget to emit the signal cellChanged() for every cell. The signal cellChanged() is connected to a function on_tableWidget_cellChanged that reads the contents of the changed cell and writes it back to DATASET. This is necessary to allow the user to change the data manually. So everytime the table is updated, its contents are written back to DATASET. Is there a way to distinguish if the cell was changed by the user or by updateTable? i thought of disconnecting on_tableWidget_cellChanged by updateTable temporarily but that seems to be a little dirty.

• JEE Web Applications vs Web Services

  - by Zac

  Can someone confirm or clarify for me: From what I can tell, JEE web apps consist of a Servlet and/or JSP driven dynamic web page being fed back in the HTTP response, triggered by the JEE server receiving a HTTP GET or POST request. From what I can tell, JEE web services also make use of Servlets as the web tier components, however a WS Servlet receives a SOAP message and validates the contents of those messages with whatever WSDL the Servlet is WARed with. The response is also packaged in SOAP and sent back to the requestor. So, from what I can tell, both JEE web apps and WSes use Servlets as the web components, with the only real difference being the protocol used (raw HTTP vs SOAP, which is an extension of HTTP). This is the best I could come up with - am I right? Totally wrong? Close?
