  • Will Bluetooth hands-free drivers be installed if BT stack doesn't support A2DP?

    - by AndrejaKo
    I have a hands-free device which has no problems being paired with windows and I can set it to be the default sound output device, I don't actually hear anything on the unit, but it worked fine with GNU/Linux and with my mobile phone. From what I can see, the cause of that is usually a problem with Bluetooth stack. I think that I have Broadcom Bluetooth stack installed, so it should be working but it isn't. To make things better, my Bluetooth radio is integrated into my laptop and manufacturer isn't providing drivers for it and Broadcom itself recently pulled support, so I can't just reinstall the stack to make sure I have newest version.

  • What's the best way to learn/increase problem-solving skills?

    - by tucaz
    Hi all! I'm not sure this is the right place to ask this question, neither if this is the right way to ask this question but I hope you help me if it is not. I work as a programmer since I was 15 (will be 24 next week) so learning programming logic was somehow natural during the course of my career and I think that it helped me to get pretty good problem-solving. One thing none of us (programmers) can deny is that programming logic helps us in a lot of fields outside computer programming. So I'd say it is a very valuable resource that one should learn. My girlfriend is not a programmer and graduated in college on a non related course (Foreign Relations) because she didn't know what to study back then. As the years passed she discovered that she liked Logistics and started to work with it almost two years ago. However, since she does not have a technical background (not even basic Math) she is really having a hard time with it. She is already trying to catch up with Math, but even simple questions/brain-teasers are hard to her. For example, trying to find the missing numbers of this sequence: 0, 1, 1, 2, 3, 5, 8, _, _, 34 and so on. We know that this is Fibonacci but if we didn't we would probably be able to get to the correct answer just by "guessing" (using our acquired problem-solving skills). I'm not sure if problem-solving skills or logic are the correct name for it, but this is what I mean: quick solve problems, brain-teasers, find patterns, have a "sharp" mind. So, the question is: what is the best way for someone to learn this kind of skills without being a programmer (or studying algorithms and such)? If you say it is a book, could you please recommend one? Thanks a lot!

  • how can I discover what keys are being sent when I press a mouse button?

    - by jcollum
    I'd like to map my Logitech MX Revolution keys in Visual Studio. More importantly, I'd like to do it without installing any software. Is this possible? I specifically want to map the two side buttons to View.NavigateBackward and View.NavigateForward. But I'm not sure what those keys are mapped to right now. I thought they were mapped to Ctrl-Tab and Shift-Ctrl-Tab, since they seem to behave that way in Notepad++, but that isn't working in VS. I'm on the work computer, which means 2 problems: I'm in Windows XP and installing software is frowned upon/monitored.

  • Boot from external usb hdd won't work in 12.04

    - by Ben Andersen
    I've been running 10.04 on an external USB HDD without problems for years. I installed 12.04 on an external USB HDD and it worked until I upgraded to all the new packages. But after that it wouldn't boot. I just got into the grub prompt. So then I tried installing on the disk inside the computer and that worked fine. But when I take it out and use it as an external USB HDD I just get: error: hd0 out of disk. grub rescue> How can I fix this? So why do I want this you might wonder? Well I have a laptop at home and a somewhat similar at work. And I just move the disk between them and don't have to move a heavy laptop. So I really hope I can continue doing this with 12.04! The old disk is only 80Gb but the new one is 320Gb (7200rpm Toshiba). I'm using 12.04 on a 64Gb SSD as an external drive and it warns about out of disk but it boots anyway most of the times.

  • What is the safest way to remove a swap partition?

    - by user212062
    I am running Ubuntu 12.04 on a 64-bit HP laptop with a 16 GB flash drive. I do not have a working hard drive right now. When I installed Ubuntu, I created a 2 GB swap partition on sdb1. I have since learned that swap partitions are generally a bad idea on flash drives, so I would like to use my swap space for my other partitions. You can see my partition scheme in the link below. I have read that I just have to comment sdb1 out of the fstab file, boot from a GParted live CD, select swapoff for sdb1, delete/merge with other partition, and everything's good. But, I've also read that messing with sdb1 can change the UUID of sdb2 or sdb3 and cause problems. Is this true? Does initramfs use swap at all? Also, when I get Ubuntu running on my laptop with an internal hard drive, does the swap partition help that much? I have 6 GB of DDR3. Does the rule of 1.5xActual RAM still apply? It seems like quite a bit to me. Thanks for the help! UPDATE: I have removed swap. The process I followed is: Right click swap partition in GParted and selected swapoff. Used # to comment the swap partition out of fstab. I tried to boot from a live GParted CD, but I kept getting an error, so I ran GParted in Ubuntu. Deleted swap partition in GParted. Unmounted /windows. Expanded /windows to take the remaining space. Mounted /windows. The / and /windows partitions each kept their own names and UUIDs, and everything is running fine. I have never seen any swap space being used before, and I don't intend to use the hibernate function, so I think removing swap was a good idea.

  • Undeliverable messages to newly migrated Exchange user

    - by johnnyb10
    We are in the process of migrating from our old domain to a new one, part of which involves migrating mailboxes from Exchange 2003 to Exchange 2007. A bunch of users have been migrated already without problems. However, one of the users is having trouble receiving emails from others. When someone sends to him, they get an Undeliverable NDR that says "A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients." The message shows the user's distinguished name as /OU=OurDomain/CN=Recipients/CN=USER57137172. The user's account name should just be "USER", so I don't know where the extra numbers ("57137172") are coming from. Thanks in advance.

  • No Visual studio template information found. See application log in Event viewer for more details

    - by sathya
    I tried installing the .NET Framework 4.0 and ASP.NET MVC 2 Framework through the web platform installer. It took a long time and finally i had a restart in between for .NET 4 installation and after that due to my system hang problems had to do a couple of restarts. And after that tried installing the ASP.NET MVC 2 alone and it succeeded. (During this time i had all my VS instances closed).  I am having VS 2008 SP1. And finally after opening VS 2008 and clicking on new project it said the above error no template info found. and i dint have even a single template in the new project template selection window. So these are the steps that i did for recovering the same.  Start Menu --> Microsoft Visual Studio 2008 --> Visual Studio Tools. Right-click over the Visual Studio Command Prompt shortcut and make sure you select Run as Administrator. Once the VS Command Prompt comes up, execute the command 1. "devenv /installvstemplates" 2. "devenv /resetsettings"  And that worked out. No Visual studio template information found. See application log in Event viewer for more detail

  • Antenna Aligner part 2: Finding the right direction

    - by Chris George
    Last time I managed to get "my first app(tm)" built, published and running on my iPhone. This was really cool, a piece of my code running on my very own device. Ok, so I'm easily pleased! The next challenge was actually trying to determine what it was I wanted this app to do, and how to do it. Reverting back to good old paper and pen, I started sketching out designs for the app. I knew I wanted it to get a list of transmitters, then clicking on a transmitter would display a compass type view, with an arrow pointing the right way. I figured there would not be much point in continuing until I know I could do the graphical part of the project, i.e. the rotating compass, so armed with that reasoning (plus the fact I just wanted to get on and code!), I once again dived into visual studio. Using my friend (google) I found some example code for getting the compass data from the phone using the PhoneGap framework. // onSuccess: Get the current heading // function onSuccess(heading) {    alert('Heading: ' + heading); } navigator.compass.getCurrentHeading(onSuccess, onError); Using the ripple mobile emulator this showed that it was successfully getting the compass heading. But it didn't work when uploaded to my phone. It turns out that the examples I had been looking at were for PhoneGap 1.0, and Nomad uses PhoneGap 1.4.1. In 1.4.1, getCurrentHeading provides a compass object to onSuccess, not just a numeric value, so the code now looks like // onSuccess: Get the current magnetic heading // function onSuccess(heading) {    alert('Heading: ' + heading.magneticHeading); }; navigator.compass.getCurrentHeading(onSuccess, onError); So the lesson learnt from this... read the documentation for the version you are actually using! This does, however, lead to compatibility problems with ripple as it only supports 1.0 which is a real pain. I hope that the ripple system is updated sometime soon.

  • Oracle Database 12c and Oracle Solaris 11 DTrace

    - by Larry Wake
    As you may have heard, Oracle Database 12c is now available for Oracle Solaris and Oracle Linux. Among other things, that means we now have the opportunity to share some of the cool things the Oracle Database and Oracle Solaris engineering teams have been doing together. And here's a good one: In this screencast, Jon Haslam describes how on Oracle Solaris 11, DTrace is now integrated into Oracle Database V$ views to provide a top-to-bottom picture of a database transaction I/O -- from storage devices, through the Oracle Solaris kernel, up to Oracle Database 12c itself: With this end-to-end view, you can easily identify I/O outliers -- transactions that are taking an unusually long time to complete -- and use this comprehensive data to identify and mitigate storage system problems that were previously extremely hard to debug. This is a great example of the power of DTrace, which is just about to celebrate its 10th anniversary in the wild. The screencast has some nice examples of DTrace's power on its own, as well as diving into the DTrace/Oracle Database 12c synergy. There's more, of course.  Over on the OTN Garage blog, Rick Ramsey has put together a nice compendium of ways the OS makes the database scream, and Ginny Henningsen's written an article on the same topic.  And, we've also got an OTN page that digs further into Oracle Database / Oracle Solaris synergies.

  • Example of persisting an inheritance relationship using ORM

    - by Schemer
    I have some experience with OOP and RDBs, but very little exposure to web programming. I am trying to understand what non-trivial types of problems are solved by ORM. Of course, I am familiar with the need for data persistence, but I have never encountered a need for persisting relationships between objects, a situation which is indicated in many online articles about ORM. I am not asking about the process of persisting a POJO to a database and restoring it later. Nor am I asking about why ORM frameworks are useful -- or a pain in the butt -- for doing so. I am particularly interested in how the need arises to persist and restore relationships between objects. In various documentation, I have seen many examples of persisting POJOs to a database, but the examples have all been for only very simple objects that are essentially nothing more than records anyway: a constructor, some private fields, and getter/setter methods. The motivation for persisting such an "object-record" seems obvious and trivial. This example: Hibernate ORM Tutorial offers such an example, but goes on to discuss mismatch issues of granularity, inheritance, identity, associations, and navigation that are not motivated by the example. If someone could offer a toy example of an instance where, say, the need arises to persist an inheritance relationship, I would be grateful. This might be blindingly obvious for anyone who has already encountered this situation but I have not and a great deal of searching and reading have not turned up any examples.

  • wine 1.4 regedit makes screen flicker on 12.04 with dual monitor setup

    - by s1lv3r
    I have a dualmonitor setup running dual 23" on 1920x1080 which has the following problem: When running any wine application (for example "wine regedit" from console) the screen flickers and the windows have artifacts like this: Also sometimes taking a screenshot using the print key will make compiz crash (starter and all window bars/menus are gone) when an wine application is started. I don't have the same problems on my notebook which has the same setup. Only difference is the notebook has ATI Graphics and this PC has nvidia. This is the output of lshw -c video: *-display Beschreibung: VGA compatible controller Produkt: G72 [GeForce 7300 LE] Hersteller: NVIDIA Corporation Physische ID: 0 Bus-Informationen: pci@0000:07:00.0 Version: a1 Breite: 64 bits Takt: 33MHz Fähigkeiten: pm msi pciexpress vga_controller bus_master cap_list rom Konfiguration: driver=nvidia latency=0 Ressourcen: irq:16 memory:fa000000-faffffff memory:d0000000-dfffffff memory:fb000000-fbffffff memory:fce00000-fce1ffff I also noticed that running xrandr from console makes the screen flicker for some seconds on this PC, which also doesn't happen on my notebook. Removing one screen from the setup will stop the flickering and the artifacts inside the wine applications from appearing. Does anybody have an advice what I could try to change to make this work?

  • Mouse doesn't work & internet connection not made in Ubuntu 12.04 LTS

    - by David Skare
    Yesterday, Nov 15, 2012, I booted into my Ubuntu 12.04 LTS system. It has resided on a Crucial 128 GB SSD with about 90% free space since early summer. I also have Windows 7 loaded on another Crucial 256 GB SSD. Ubuntu has set up a dual boot system for me even though each OS has its own SSD. I have been using this setup without problems since summer. Yesterday, when the boot process finished, my Microsoft Comfort Mouse 3000 did not work and there was a message that Ubuntu was not connected to the internet. So w/o the mouse I was forced to turn the machine off manually. About 4 days ago Ubuntu worked fine and booting into Win 7 also works fine. I have a backup machine with the same style mouse on it so I swapped the mouse onto this system. Same results. But both mice work when booting into Win 7. Today I removed both SSDs and installed my Ubuntu 12.04 HD which has not been used since I moved Ubuntu to the SSD from it. Same results. Between the last time I used Ubuntu 12.04 on the SSD and when I tried to use it again I made no changes to my machine, either hardware or software. My machines specs are: AMD FX-6100, MSI 990FXA-GD65 AM3+ format with latest BIOS (Ver 19.9), Corsair Vengeance 1866 MHz memory - 16 GB (4GB X 4 sticks), MSI N580GTX video card (nVidia 306.97 drivers), Sony Bravia 32" HD TV as a monitor, Pioneer BluRay DVD-RW, DSL connection to internet thru a router (10 mps), Crucial 128 GB SSD (90% free space), Microsoft Comfort Mouse 3000 I try to maintain current BIOS and drivers for all devices. I mostly use my Ubuntu system for programming in GCC and OpenCOBOL, surfing the internet and e-mailing. No games are installed. I'm stumped! If anyone has experienced this same problem I'd appreciate knowing how you solved it. TIA, Dave

  • Broke Ubuntu 12.04 either with Screencloud or Ubuntu Tweak

    - by pgrytdal
    Earlier today I installed the Screen Shot app "Screencloud" and after the installation Firefox was having problems. I didn't think much about it, just closed Firefox, then proceeded to change the toolbar opacity on Ubuntu Tweak. After restarting my system, hoping it would fix Firefox (because, you know, restarting fixes everything ;) ) I am able to go to the Log In Screen, type in my password, but then I get 3 errors regarding the Screencloud Ubuntu One, Imgur, and Dropbox plugins. After clicking the "Okay" on all three errors, all I see is my wallpaper. I am not able to access the terminal VIA CtrlAltT, but I am able to log out VIA CtrlAltDelete. I have tried all desktop environments I have installed (that, except for Unity 2D, has to do with Cairo Dock.) I hope I have provided enough information. If you need more, please ask. Please help! I would like to not have to re-install Ubuntu. Other info: OS: Ubuntu 12.04 I also have a Ubuntu 12.10 Live USB, but Ubuntu 12.10 hasn't run very well on any of my computers.

  • IE8 complains about SSL name mistmatch

    - by Cerin
    When visiting an SSL protected website, IE8 complains about the certificate name not matching the website address, but gives no information about the certificate or what name it's looking for. Visiting the same site in IE9 (or IE9 in "IE8 mode"), Firefox, Chrome, and Safari shows no problems, and that the certificate matches the address. Certificate checkers indicate everything is installed and configured correctly. Does anyone know what might be causing this? Is this a known issue or bug in IE8? I've been Googling for similar issues, but due to the uncertainty as to what's actually going on, I'm not sure what to search for. My problem reads similar to this question. However, my server is running Apache2.

  • how to install curl 13.04 with depency error

    - by whale_steward
    how to install curl in ubuntu 13.04? it always throw this error : Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: curl : Depends: libcurl3 (= 7.29.0-1ubuntu3) but 7.29.0-1ubuntu3.2 is to be installed E: Unable to correct problems, you have held broken packages. when using sudo apt-get update, it shows: 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. here are the steps i had done : using sudo apt-get install curl removing google-chrome-stable and chromium browser then sudo apt-get install curl use sudo apt-get autoremove && sudo apt-get autoclean && sudo apt-get clean then run the 1st step again. also i have tried : How do I resolve unmet dependencies? and still throw the same error. at this point i dont know what i did wrong, is curl impossible to install in ubuntu ?

  • Rendering a big game universe - bitmaps or vector graphics?

    - by user1641923
    I am new to an Android development, though I have much experience with Java, C++, PHP programming and a bit experience with vector graphics too (basic 3d Studio Max, Flash, etc). I am starting to work on an Android game. It is going to be a 2D space shooter/RPG, and I am not going to use any game engines and any 3D party libs. I really want to create a very large game universe, or even pseudo-infinite (without visible borders, as if it were a 2D projection of a sphere). It should include 10-12 clusters of 7-8 planets/other space objects and random amount of single asteroids/comets, which player can interact with and also not interactive background. I am looking for a least complicated aproach to create such a universe. My current ideas are: Simply create bitmaps with space scenery background so that they can be tiled seamlessly repeated and construct my 2D universe of this tiles, then place interactive objects (planets, other spaceships) on it. Using vector graphics. I would have a solid color background, some random background objects and gradients here and there. My problems here: Lack of knowledge of how well vector graphics is integrated in Android. Performance? Memory usage? Does Android manage big bitmaps well? Do all of the bitmaps have to be in memory during all game process? I am interested in technical details regarding each of the ideas and a suggestion, which I should go with.

  • Physics not synchronizing correctly over the network when using Bullet

    - by Lucas
    I'm trying to implement a client/server physics system using Bullet however I'm having problems getting things to sync up. I've implemented a custom motion state which reads and write the transform from my game objects and it works locally but I've tried two different approaches for networked games: Dynamic objects on the client that are also on the server (eg not random debris and other unimportant stuff) are made kinematic. This works correctly but the objects don't move very smoothly Objects are dynamic on both but after each message from the server that the object has moved I set the linear and angular velocity to the values from the server and call btRigidBody::proceedToTransform with the transform on the server. I also call btCollisionObject::activate(true); to force the object to update. My intent with method 2 was to basically do method 1 but hijacking Bullet to do a poor-man's prediction instead of doing my own to smooth out method 1, but this doesn't seem to work (for reasons that are not 100% clear to me even stepping through Bullet) and the objects sometimes end up in different places. Am I heading in the right direction? Bullet seems to have it's own interpolation code built-in. Can that help me make method 1 work better? Or is my method 2 code not working because I am accidentally stomping that?

  • Sharing internet connection from Windows XP using wi-fi router

    - by Darius
    Hi, I have an network configuration like: Ethernet cable from ISP connected to Windows XP machine, configured with static IP 192.168.0.3 Another ethernet connection from 2nd Windows XP machine's network adapter to a Wi-Fi router (D-Link Airport G+) XP set to "Share internet connection", the 2nd adapter configured as static to 192.169.0.1 D-Link Airport Wi-Fi router also configured as "static connection", it's IP set to 192.169.0.2, default gateway set to 192.169.0.1. Network mask everywhere is 24. Laptop computer connected with the router with static IP 192.169.0.3 The problems are: XP machine sees the router (it's able to ping it and access it via the web admin tool) The router somehow cannot PING the XP machine (using the tool provided by the web-based admin tool) The laptop computer cannot ping anything and cannot be pinged The router is only accessible when the ethernet cable is connected with a router's 1-4 LAN port, when I connect it via "WAN" port (which I believe is the proper one) it's not visible from the XP machine If you have similar experience with configuring a network like this I would really appreciate your help. I cannot use the Wi-Fi router with the ISP cable itself.

The problem is that i want each request to be in a new process of php-fpm. In a few words i don't want to have idle timeout for a process but instead i want them to close instant when a request is being closed. With idle timeout i have huge problems which are hard to explain at the moment but i'm really sure that if i disable the idle timeout everything will be perfect. Is there any way to do this?

  • MacBook Pro screen goes dark

    - by Mike M
    I've had my MacBook Pro for two years now; no problems so far (it has had 3rd party RAM from the get go). Today, I'm copying a particularly large VM from an External disk drive to local MacBook disk. It has about 3GB to go and I take off to do some other things and when I come back my screen is "dark". The computer is still on but I can't see anything. I forced a reboot by holding down the power button, it starts up with the "chimes", but still no screen. I've done this several times. Any ideas? Do you think the hard disk activity caused it to get too hot?

  • Windows 2000 under Windows 7 Virtual PC not working correctly

    - by dave
    I have just moved my Windows 2000 Virtual PCs from Vista to Windows 7 Professional (64-bit). The machines work to a point but I have found some problems: drive mapping does not seem to work any more. I need this to exchange data. I do not need network access to the virtual PC so would rather leave it unconnected. the virtual PC would automatically shutdown the session and go to the login screen after a few minutes of inactivity. I tried installing the Virtual PC Integration Components but the install failed (one of the messages basically says it's XP+ only). Now I'm stuck in 640x480 mode with mouse capture. I have heard that you can install an older version of the Integration Components but this sounds a bit suspect. Does anyone have any ideas on how to get Windows2000 working with drive sharing on a Virtual PC?

  • Should we choose Java over C# or we should consider using Mono?

    - by A. Karimi
    We are a small team of independent developers with an average experience of 7 years in C#/.NET platform. We almost work on small to average web application projects that allows us to choose our favorite platform. I believe that our current platform (C#/.NET) allows us to be more productive than if we were working in Java but what makes me think about choosing Java over C# is the costs and the community (of the open source). Our projects allow us even work with various frameworks as well as various platforms. For example we can even use Nancy. So we are able to decrease the costs by using Mono which can be deployed on Linux servers. But I'm looking for a complete ecosystem (IDE/Platform/Production Environment) that decreases our costs and makes us feel completely supported by the community. As an example of issues I've experienced with MonoDevelop, I can refer to the poor support of the Razor syntax on MonoDevelop. As another example, We are using "VS 2012 Express for Web" as our IDE to decrease the costs but as you know it doesn't support plugins and I have serious problems with XML comments (I missed GhostDoc). We strongly believe in strongly-typed programming languages so please don't offer the other languages and platforms such as Ruby, PHP, etc. Now I want to choose between: Keep going on C#, buy some products and be hopeful about openness of .NET ecosystem and its open source community. Changing the platform and start using the Java open source ecosystem

  • What do you do to make sure you take proper/enough breaks, while avoiding unwanted side-effects of break taking?

    - by blueberryfields
    preamble It seems to me that computer programmers are one of a select few groups of people who actually take pleasure from sitting in front of computers for long periods of time. Most people in other professions actively dislike their time at computers, and do their best to avoid it (so, I assume, they don't have problems taking breaks). At least for me, having external cues for taking breaks, and clear instructions on what to do with each break (stretch, go for a walk, close my eyes, look into a distance of preferably a few km and focus on faraway objects, etc...), is a must. So far, I've just been making up the breaks and tools to get them as I go along, based on what looks to be low-specificity information found on the net (generic stuff ala ergonomics advice for office staff).
