• Mimicking a bluetooth disconnection

  - by user2529672

  I've written a program to control a bluetooth device. I'm trying to test cases when the bluetooth disconnects, i.e. if its out of range. Physically taking the device out of range is one possibility, but its quite cumbersome and I have to go outside my office to achieve this. What can I do to trigger a disconnection? Is there, for example, an interferer I can setup, say with an Android phone, that would make the connection drop? Or limit the Bluetooth transmit power? Any other possibilities?

• code cowboy on the team

  - by MK01

  How do you deal with a team member who is senior to you and always jumps on other people's projects and completes them over night or over the weekend? She seems to work 80 hour weeks whether there is an emergency or not and it is somewhat difficult to predict which part of your todo list she is going to strike next. Sometimes days of your work are wasted because on Monday morning you find a checkin completing the project you've spent most of the previous week working on. To people asking of the quality: Usually it is quite good but: there is also a lot of refactoring of code involved, including code 'owned' by other team members, w/o regard for the test coverage, with the obvious results.

• Is this a valid HTTP response? [migrated]

  - by fatmck

  I am writing a web server using C++, which responds the following for all requests: static std::string rsp[] = { "HTTP/1.1 200 OK\r\n", "Server: WebServer\r\n", "Content-Type: text/html\r\n", "Content-Length: 3\r\n", "Connection: close\r\n", "\r\n", "123" }; the content "123" can be successfully shown in browser. But when I use apache-ab to do a test, ab always show errors like this: ab -n 1 -c 1 http://127.0.0.1:1080/ apr_socket_recv: Connection reset by peer (104) I thought that I'm closing the socket too quickly, so I commented the close() function. But ab just hold, ab seems to be waiting for a complete response.

• What is the current state of apple device (iPhone, iPod, etc.) support?

  - by BullfrogBlues

  What ubuntu applications provide support? (guides, how to's, status) Also, specifically, details on support for syncing music to iPhone's and iPod's with the latest OS version, as of writing iOS 5: Can you sync music to apple devices using iOS5? (iPhone & iPod) What applications allow you to do this and how? (guides, how to's, status) What has already been established is: Apple does not support Linux and has no plans to. libimobiledevice seems to provide some support but does not support syncing music with devices using iOS5. (I can't test libmobiledevice with anything other iOS5, so I can't provide details on how that works)

• How do I get drivers working for an Nvidia GT560i on 12.04?

  - by keepitsimpleengineer

  I been using a test Xubuntu 12.04 LTS on my 64 bit workstation, because Ubuntu has dropped support for the nvidia graphic adapters my 10.04 LTS and I haven't been able to get them working. Now update manager has upgraded the kernel from 3.2.0-30-generic to 3.2.0-31-generic, and failed to produce a working nvidia module that the X server can load. Fortunately, when launching the 3.2.0-30-generic kernel, I still have use of the X server. Does anybody know a work-around or fix for this? I'm really worried, this is the last working Ubuntu distribution OS on the computer and I don't want to give up on Ubuntu. Details of problem here.

• How do I get started with HTML5? [closed]

  - by daniel.sedlacek

  What is the recommended workflow to learn HTML5? What tools should I install? What SDK? Where to start? How to test? How to debug? What do I read? I understand that what is often labelled as "HTML5 development" is in fact a mixture of HTML, CSS, JS and more, however I don't believe that bigger projects are developed in Notepad. That is why I am asking you to reveal your tips and tricks about your workflow.

  - by C4CodeE4Exe

  I am bit confusing about my goals although whole motivation thing is $$$ but still there is something pushing me to pursue higher studies(being frustrated from boot-licking attitudes of peers and lottery system here in India for promotions,pay hikes and onshore opportunities). I am afraid I do not have any goals.I am software developer mainly in JAVA, but an ECE graduate.I want to work in programming languages. My problem is that I am not even Jack of all trades.I have experience in programming and thats where I am good(self-pro-claimed or atleast people say this treating them as a critics). I have decided to go with the wind and applying for programming languages as my specialization.But I know how to code,write test cases,how Perosnal and commercial IT insurances solution works.What I do not know is how to show that what I will do during my masters.I have no idea about what to showcase, how would my work ex will help me. totally oblivious thoughts... thanks waiting for replies....

• Why support IE6?

  - by TATWORTH

  The question has been raised as to why support IE6? I can give you two reasons, why your client will require IE6 to be supported: While IE6 continues to have above a certain of browsers in use The web application is for a controlled environment that has not been upgraded from IE6 to a later version I personally only use any current or previous version of IE to: To access the Windows Update site As required to test IE compatibility of applications that I write I agree that that the CSS fixes required to support IE6 are undesirable in that they require non-standards compliant CSS. I prefer that my HTML be both XHTML and CSS standards complaint according to the W3C tests. IE9 promises to be not only standards compliant but much better in performance. I am looking forward to its release.

  Un virus biologique utilisé à bon escient pourrait augmenter par dix la capacité des batteries Selon des chercheurs américains Les virus sont connus pour leur capacité de duplication et de destruction. Des chercheurs estiment avoir trouvé le moyen d'exploiter à bon escient leur capacité d'auto-renouvellement. En particulier le virus de la mosaïque du tabac (TMV) qui s'attaquent habituellement aux plantes, en particulier le tabac et les tomates.

• How can I run everything as root

  I have dual booted to lubuntu (with Windows XP) and everytime and then I'm getting asked for my password. How do I run everything as root and not ask a password again?

• Cannot load a webpage with hp pavilion dv2000 laptop

  - by Andre'

  I am using an Ubuntu 12.04 cd to test out the os before I take the plunge, and I can't get webpages to load in the firefox application. When I look at the wireless settings, ubuntu says that my computer is connected to my home wireless network, but I am repeatedly prompted to enter my password (it keeps telling me that authentication is required by my wireless network). After a few rounds of this, Ubuntu seems to give up and tells me that wireless network is disconnected. Furthermore (I'm currently in ubuntu using a wired connection if it has anything to do with this), the wireless connection will randomly attempt to establish itself. I've entered rfkill list and all of the wireless devices therein say "no" - they're not blocked. I can connect to the network in Windows 7, so I don't think my network is the problem. Any suggestions?

• Ubuntu Server - Virtual Box?

  - by user186144

  So I got VirtualBox just for Ubuntu Server, I'm currently Running Ubuntu 12.04 as my main OS. But when I got everything set up in Ubuntu Server 12.04, including my ports forwarded and a test Minecraft server up... I realized that nobody could join my public IP I sent out, not even me! I can connect to the ipv4 address. It acts like I didn't forward my ports. But I forwarded 25565 to Input and Output and they're both TCP and UDP. Is this just a virtual box issue or am I doing something wrong? * Using Eth0 wired connection

• External link tracking when opening the link in a new window in Google Analytics?

  - by evanmcd

  OK, so this seems like a really simply problem, but I have yet to find a solution that accomplishes the following: Opens the link in a new window Tracks the event in GA (obviously) Doesn't trigger pop-up blockers (uses target="_blank" instead of window.open) Most of the code I've seen, including Google's, doesn't take into account the case of opening in a new window - they just window location.href. Even GAAddons (http://gaaddons.com/), which charges for commercial use, doesn't seem to work for me. Perhaps, I'm missing something simple - I'd be relieved if so and would thank profusely whoever points it out to me! If no one is able to provide an example, I'll post some of the test cases I've created to illustrate the problem. Thanks.

• The Ubuntu App Showdown -Specific software

  - by Stefanie

  I would like to participate the contest but I'm programming very specific scientific tools for the work in a molecular biological lab. I know that I won't win with such an app but it's a nice possibility to get into Qickly and Ubuntu Apps since I'm only programming for Windows at the moment. My question is, whether I have a possibility to explain what my software is doing and for what it is good in the lab. Also I have to provide some test data, that the jury can try it out. Is this possible and how I can submit those additional information?

• Amnesic Environment

  - by Mike Clark

  My team is looking for a technical term which may or may not exist. We are trying to describe an environment, such as a database, which has been built up over time with little or documentation about the change process that has gone into it. Generally these are legacy systems who's original developers have long since moved on and they are in such a tangled and unmanageable state that the only way to recreate the environment, say for testing purposes, is to copy it and do your best guess at re-configuring it for its new purpose. So far the best term we have come up with is Amnesic, such as "setting up the new test environment is going to be a challenge because it is an amnesic db." However, we are still not quite happy with the term and were wondering if a better and/or more accepted term for this situation exists.

• Where would a senior PHP developer locate the method getActiveEntries()?

  - by darga33

  I have a class named GuestbookEntry that maps to the properties that are in the database table named "guestbook". Very simple! Originally, I had a static method named getActiveEntries() that retrieved an array of all GuestbookEntry objects. Each row in the guestbook table was an object that was added to that array. Then while learning how to properly design PHP classes, I learned some things: Static methods are not desirable. Separation of Concerns Single Responsibility Principle If the GuestbookEntry class should only be responsible for managing single guestbook entries then where should this getActiveEntries() method most properly go? Update: I am looking for an answer that complies with the SOLID acronym principles and allows for test-ability. That's why I want to stay away from static calls/standard functions. DAO, repository, ...? Please explain as though your explanation will be part of "Where to Locate FOR DUMMIES"... :-)

• How can I track a falling ball with a camera?

  - by Jason

  I have been trying to get my camera to follow a falling ball but with no success. here is the code float cameraY = (FrustumHeight / 2)+((ball.getPosition().y) /2) - (FrustumHeight /2); if (cameraY < FrustumHeight/2 ) cameraY = FrustumHeight/2; camera.position.set(0f,cameraY, 0f); Gdx.app.log("test",camera.position.toString()); camera.update(); camera.apply(Gdx.gl10); batch.setProjectionMatrix(camera.combined); batch.begin(); batch.draw(backgroundRegion, camera.position.x - FrustumWidth / 2, -cameraY - (FrustumHeight/2) , 320, 480); batch.draw(ballTexture, (camera.position.x - FrustumWidth / 2) + ball.getPosition().x,-cameraY + ball.getPosition().y - (FrustumHeight/2) , 32, 32); I'm sure I am doing this completely wrong - what is the correct way to do this?

• After upgrade my webcam mic records fast, high pitched, and squeaky only in Skype (maybe Sound Recorder problem too)

  - by Dennis

  After an upgrade to 11.10 which probably also updated Skype to 2.2.35 (not sure because I never checked the version before) the sound that comes back from an echo test is very high pitched and squeaky. I'm not sure if when in a call if the other person can't hear or just doesn't know what they are hearing. I am using a USB Logitech C250 Audacity records fine, gmail video chat works fine, but if I start sound recorder I get a "Could not negotiate format", followed by "Could not get/set settings from/on resource". I don't know if this is a Skype problem or a wider Pulse problem. My only real needs are the gmail and Audacity, though I have a couple of contacts that I can only Skype with.
