  • pulseaudio on ubuntu server

    - by Dan
    I am running ubuntu server, and trying to get pulseaudio working. I followed the instructions at How do I run PulseAudio in a headless server installation? At the moment, pacmd list-cards is reporting 0 cards, and I suspect this has something to do with the fact aplay is only playing sound when I run it as sudo. As far as I can tell, this means the the kernel module for my sound card is in fact loaded. I have already tried adding my user to the "audio" group, but this does not help. My questions are 1) How do I get aplay to work without running it as sudo 2) Is there anything special I need to do to make pulseaudio work at this point.

  • Synchronization between game logic thread and rendering thread

    - by user782220
    How does one separate game logic and rendering? I know there seem to already be questions on here asking exactly that but the answers are not satisfactory to me. From what I understand so far the point of separating them into different threads is so that game logic can start running for the next tick immediately instead of waiting for the next vsync where rendering finally returns from the swapbuffer call its been blocking on. But specifically what data structures are used to prevent race conditions between the game logic thread and the rendering thread. Presumably the rendering thread needs access to various variables to figure out what to draw, but game logic could be updating these same variables. Is there a de facto standard technique for handling this problem. Maybe like copy the data needed by the rendering thread after every execution of the game logic. Whatever the solution is will the overhead of synchronization or whatever be less than just running everything single threaded?

  • Do immutable objects and DDD go together?

    - by SnOrfus
    Consider a system that uses DDD (as well: any system that uses an ORM). The point of any system realistically, in nearly every use case, will be to manipulate those domain objects. Otherwise there's no real effect or purpose. Modifying an immutable object will cause it to generate a new record after the object is persisted which creates massive bloat in the datasource (unless you delete previous records after modifications). I can see the benefit of using immutable objects, but in this sense, I can't ever see a useful case for using immutable objects. Is this wrong?

  • MCM Lab exam this week

    - by Rob Farley
    In two days I’ll’ve finished the MCM Lab exam, 88-971. If you do an internet search for 88-971, it’ll tell you the answer is –883. Obviously. It’ll also give you a link to the actual exam page, which is useful too, once you’ve finished being distracted by the calculator instead of going to the thing you’re actually looking for. (Do people actually search the internet for the results of mathematical questions? Really?) The list of Skills Measured for this exam is quite short, but can essentially be broken down into one word “Anything”. The Preparation Materials section is even better. Classroom Training – none available. Microsoft E-Learning – none available. Microsoft Press Books – none available. Practice Tests – none available. But there are links to Readiness Videos and a page which has no resources listed, but tells you a list of people who have already qualified. Three in Australia who have MCM SQL Server 2008 so far. The list doesn’t include some of the latest batch, such as Jason Strate or Tom LaRock. I’ve used SQL Server for almost 15 years. During that time I’ve been awarded SQL Server MVP seven times, but the MVP award doesn’t actually mean all that much when considering this particular certification. I know lots of MVPs who have tried this particular exam and failed – including Jason and Tom. Right now, I have no idea whether I’ll pass or not. People tell me I’ll pass no problem, but I honestly have no idea. There’s something about that “Anything” aspect that worries me. I keep looking at the list of things in the Readiness Videos, and think to myself “I’m comfortable with Resource Governor (or whatever) – that should be fine.” Except that then I feel like I maybe don’t know all the different things that can go wrong with Resource Governor (or whatever), and I wonder what kind of situations I’ll be faced with. And then I find myself looking through the stuff that’s explained in the videos, and wondering what kinds of things I should know that I don’t, and then I get amazingly bored and frustrated (after all, I tell people that these exams aren’t supposed to be studied for – you’ve been studying for the last 15 years, right?), and I figure “What’s the worst that can happen? A fail?” I’m told that the exam provides a list of scenarios (maybe 14 of them?) and you have 5.5 hours to complete them. When I say “complete”, I mean complete – you don’t get to leave them unfinished, that’ll get you ‘nil points’ for that scenario. Apparently no-one gets to complete all of them. Now, I’m a consultant. I get called on to fix the problems that people have on their SQL boxes. Sometimes this involves fixing corruption. Sometimes it’s figuring out some performance problem. Sometimes it’s as straight forward as getting past a full transaction log; sometimes it’s as tricky as recovering a database that has lost its metadata, without backups. Most situations aren’t a problem, but I also have the confidence of being able to do internet searches to verify my maths (in case I forget it’s –883). In the exam, I’ll have maybe twenty minutes per scenario (but if I need longer, I’ll have to take longer – no point in stopping half way if it takes more than twenty minutes, unless I don’t see an end coming up), so I’ll have time constraints too. And of course, I won’t have any of my usual tools. I can’t take scripts in, I can’t take staff members. Hopefully I can use the coffee machine that will be in the room. I figure it’s going to feel like one of those days when I’ve gone into a client site, and found that the problems are way worse than I expected, and that the site is down, with people standing over me needing me to get things right first time... ...so it should be fine, I’ve done that before. :) If I do fail, it won’t make me any less of a consultant. It won’t make me any less able to help all of my clients (including you if you get in touch – hehe), it’ll just mean that the particular problem might’ve taken me more than the twenty minutes that the exam gave me. @rob_farley PS: Apparently the done thing is to NOT advertise that you’re sitting the exam at a particular time, only that you’re expecting to take it at some point in the future. I think it’s akin to the idea of not telling people you’re pregnant for the first few months – it’s just in case the worst happens. Personally, I’m happy to tell you all that I’m going to take this exam the day after tomorrow (which is the 19th in the US, the 20th here). If I end up failing, you can all commiserate and tell me that I’m not actually as unqualified as I feel.

  • Fastest way to get up to speed on webapp development with ASP.NET?

    - by leeand00
    I'm trying to get better at C# ASP.NET 3.5 development (...no none of that MVC stuff :), and fast! My boss gave me a book to read on it from Wrox, but the thing reads like a history novel, telling you how things worked as far back as ASP.NET 1.0; The web application we are developing is completely in ASP.NET 3.5 so I don't need to read through any of the history (maybe I'm wrong about that...but I don't really have the time to read about that...) Do you have any suggestions for a faster (book, series of tutorials) to come up to speed on it? I'd like to learn about UI components, database access, etc... P.S. In a previous position I was an JSP/J2EE developer (and I used MVC all the time! :-D) P.S.S. I did take a course on it in 2008 at some point, but it seemed all very pointy and clickly. I wanna learn the code stuff! The how it works, and where the events are!

  • Unity3D: How To Smoothly Switch From One Camera To Another

    - by www.Sillitoy.com
    The Question is basically self explanatory. I have a scene with many cameras and I'd like to smoothly switch from one to another. I am not looking for a cross fade effect but more to a camera moving and rotating the view in order to reach the next camera point of view and so on. To this end I have tried the following code: firstCamera.transform.position.x = Mathf.Lerp(firstCamera.transform.position.x, nextCamer.transform.position.x,Time.deltaTime*smooth); firstCamera.transform.position.y = Mathf.Lerp(firstCamera.transform.position.y, nextCamera.transform.position.y,Time.deltaTime*smooth); firstCamera.transform.position.z = Mathf.Lerp(firstCamera.transform.position.z, nextCamera.transform.position.z,Time.deltaTime*smooth); firstCamera.transform.rotation.x = Mathf.Lerp(firstCamera.transform.rotation.x, nextCamera.transform.rotation.x,Time.deltaTime*smooth); firstCamera.transform.rotation.z = Mathf.Lerp(firstCamera.transform.rotation.z, nextCamera.transform.rotation.z,Time.deltaTime*smooth); firstCamera.transform.rotation.y = Mathf.Lerp(firstCamera.transform.rotation.y, nextCamera.transform.rotation.y,Time.deltaTime*smooth); But the result is actually not that good.

  • Online resizing of kvm guest root filesystem?

    - by Bittrance
    I have a Linux guest that uses an LVM volume directly as root file system (that is, there is no partition table). libvirt config looks thus: <os> <type arch='x86_64' machine='rhel6.4.0'>hvm</type> <kernel>/boot/vmlinuz-X.Y.Z.el6.x86_64</kernel> <initrd>/boot/initramfs-X.Y.Z.el6.x86_64.img</initrd> <cmdline>console=ttyS0 root=/dev/vda</cmdline> <boot dev='hd'/> </os> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/vg/guest'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </disk> From inside the guest: $ mount /dev/vda on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) Is it possible to resize the guest's root partition without rebooting the guest? Just doing lvextend on the host and resize2fs from the guest does not seem to be enough.

  • Finding complexity of a program as a service [on hold]

    - by Seshu
    I would like to find the complexity of a specific code chunk written in Java. Is there a place/web site/service where I can find out the complexity of any arbitrary program. This program might include loops/recursion. Using theory we can compute complexity ourselves. But, just curious in finding if any service is out there to find such complexity. We have several code quality related tools does any of such tools will also find complexity of given code? Could any one point me or direct me to such a utility/site/service?

  • Best tutorial ever! Is there one just like it for XHTML and CSS...?

    - by Joshua C
    I have been learning Ruby on Rails using www.railstutorial.org, and I LOVE it! My only problem? Well, I can build the applications just fine, but my knowledge of designing the skin (CSS) of the application is limited. Is there a really good XHTML and CSS which is very similar to the Ruby on Rails Tutorial by Michael Hartl? If not, perhaps you can point me towards some of the best? Thanks, Joshua Collins P.S. Only if Michael would create a CSS and XHTML tutorial himself... sigh

  • Release an upgraded iOS app with a different revenue model

    - by tassock
    I am starting a new iOS project and initially plan release a simple free version to gather feedback. I don't intend to monetize or market this initial version. However, I believe "Version 2" of this app will be good enough to pay for. I would prefer to release Version 2 as an upgrade from Version 1 rather than release it as a separate app. This way I can reserve a name for the app. It will also be easier to keep everything in a single repository. Are there any downsides of this approach? It's my understanding that I can change the price of an app at any point in time, so it shouldn't be an issue transitioning to a paid app, should it?

  • How to position a sprite in a 2D animation skeleton?

    - by Paul Manta
    Given two joints that define a bone, I would like to know how to decide where, between those two joints, I should draw the sprite. This should be a fairly simple thing to solve, but there is one thing that I am not sure about. After I've determined the rotation of the sprite (which is the absolute angle the joints form with the x-axis), I also need to determine the origin point from where I need to start drawing the transformed image. So how should I position the sprite between the two joints? Should I make the center of the image be the midpoint between the two joints, or should I make one the of the joints be the origin? Do these things matter that much (could the wrong positioning make the sprite move oddly during the animation)?

  • Is it a good idea to create shared UI library that would render natively on different platforms?

    - by Maciej Donajski
    I am designing an application that has following flow: User designs a form using web application (J2EE backend application) The form is sent to mobile device (Android) Mobile device User fills out the form designed in 1. Results are synced with backend. One of my ideas is to create a common java UI library for creating the type of forms that I need. This library would also have a native renderers for different platforms (Web and Android would be implemented first). The whole point of it is to have a native experience on web and android side. Are there any existing solutions to meet the requirements that I have? Is it a good approach to achieve them?

  • Thinkpad x201 Tablet - Touch doesn't work correctly under 12.04

    - by Joachim
    running 12.04 on my Thinkpad X201t. On the login screen the touch works fine, the mouse cursor appears where I touch the screen. After I logged in, it doesn't work anymore. If I touch the display, the cursor stays on the point where it was before, it doesn't jump to the touchpoint. I can move it, yes, but its chaotic. With the pen it works fine, but without the touch-function it's not enought for real tablet usage. So, would be glad if touch-function can be fixed. I'm very new to Linux/Ubuntu, so don't know where I can start. Haven't found anything in the system settings & Compiz so far, also no luck in google etc. Would be glad for help ;-). Of course I could go back to 11.04... but I would prefer to stay with the new system. Best, Joachim

  • DMG image containing Mac OS X 10.6.5 update not recognized

    - by Lawliet
    Hello, I want to update my Mac OS X 10.6.3 and want to use the manual package update (not Software Update) and I am having this problem for two days now. First I downloaded Mac OS X 10.6.5 Combo update and on the first opening it popped up a message saying "Unable to mount: disk image not recognized". I thought that somehow the image became corrupt during the download, so I downloaded it again. Same result. And I downloaded again. And again... No use, it still states that the .dmg is not recognized. Then I tried to update my system from 10.6.3 to 10.6.4 using the same method (package installer). It worked. And of course I downloaded the 10.6.5 update (not the combo package, but the 10.6.4 10.6.5 update package)... guess what. Not recognized. I don't understand how is this possible. Did anyone has the same problem? Please don't advice me to use software update, as I need to do that on multiple Macs Thanks in advance.

  • If Expression True in Immediate Window But Code In if Block Never Runs

    - by Julian
    I set a break point in my code in MonoDevelop to break whenever I click on a surface. I then enter the immediate window and test to see if the the if statement will return true in comparing two Vector3's. It does return true. However, when I step over, the code is never run as though the statement evaluated false. Does anyone know how this could be possible? I've attached a screenshot. Here is the picture of my debug window and immediate window. You can see where the immediate window evaluates to true. The second breakpoint is not hit. Here are the details of the two Vector3's I am comparing. Does anyone know why I am experiencing this? It really seems like an anomaly to me :/ Does it have something to do with threading?

  • how to initialize two logical drives on a HP P400i controller without reboot

    - by John
    What I am trying to do is initialize two logical drives on a HP P400i embedded controller without a reboot of the system here my current Array config: array A (SAS, Unused Space: 0 MB) logicaldrive 1 (17.9 GB, RAID 5, OK) logicaldrive 2 (17.9 GB, RAID 5, OK) logicaldrive 3 (75.9 GB, RAID 5, OK) logicaldrive 4 (25.0 GB, RAID 5, OK) physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 72 GB, OK) physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 72 GB, OK) physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 72 GB, OK) array B (SAS, Unused Space: 0 MB) logicaldrive 5 (99 MB, RAID 0, OK) logicaldrive 6 (68.2 GB, RAID 0, OK) physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 72 GB, OK) windows 2003 machine running the HpCISs2.sys driver version 6.20.0.32 . I have the ACU and ACU CLI tools installed version 8.28.13.0, P400i firmware version 2.74 . Now what I'd like to do is removes the physical drive 1I:1:4 and delete the two logical drives in array B. then insert a new drive in to bay 4 that contains two new logical drives and have them show up in array B again. So far after I remove the drive and delete the failed logical drives, I insert the new drive and run HPacucli rescan. I get the new drive to show up as unassinged physical drive but I cant figure out now to "for lack of a better word" mount the 2 logical drives on the new unassinged disk. If I reboot the system the array controller picks up the new fourth drive and creates Array B with the drives without problem but I'd really like to not have to reboot the server. Any ideas?

  • Serve most of a domain with Apache, but use mod_proxy to serve some URLs from Lighttpd

    - by Alex Pineda
    So we wish to host some pages on a new server with apache2, and embed some of our old content & functionality from another server with lighttpd in an iframe. I'm looking at this configuration from the apache docs (http://httpd.apache.org/docs/2.2/vhosts/examples.html#page-header) under "Using Virtual_host and mod_proxy" together. <VirtualHost *:*> ProxyPreserveHost On ProxyPass / http://192.168.111.2/ ProxyPassReverse / http://192.168.111.2/ ServerName hostname.example.com </VirtualHost> The only issue is that I want to proxy only on a subdomain, or even better, if I can keep the top domain and proxy only if the url contains a particular path ie. "/myprocess.php". So in essence the DNS will point to the apache2 as the "master router".

  • How do bug reports factor in to a sprint?

    - by Mark Ingram
    I've been reading up on Scrum recently. From my understanding, a meeting is held before the sprint starts, to decide what gets moved from the product backlog to the upcoming sprint backlog. Once a feature is completed in the current sprint, it will go into the "Ready to QA" bucket, and it's at this point that I'm getting confused. Do bug reports go back into the product backlog? I assume they can't go back into the sprint backlog as we've already decided what work will be done for this cycle? What happens when QA finds a bug? Where does it go?

  • How long should my Html Page Title Really be?

    - by RandomBen
    How long should my text within my <title></title> tags really be? I know Google cuts it off at some point but when? When I used IIS7's SEO Toolkit 1.0 I get error stating my title should be under 65 characters. I have a book by Bruce Clay that states I should use from 62-70 characters and roughly 9 +/- 3 words. I also have used SenSEO's Firefox Add-on and it states I should use a max of 65 characters or roughly 15 words. What is the max really? I have 2 sources saying 65 and 1 saying 72 but Bruce Clay is generally kept in high regard.

  • modifying openssl library code

I've read that the encryption operation occur in libcrypto in openssl. when I tried to compile and install OpenSSL from source ..I had everything ok with the installation, but when to check the version installed on the system, with "dpkg -s openssl", it didn't seem that it's the version i had already installed, maybe it had been installed successfully, but the question is: would it be the version the system use for encryption operations? would it overwrite the old version? and would my changes in code have effects ? any help please? thank you in advance.

  • Any good, easy to learn from books or tutorials for learning assembly? [on hold]

    - by pythonian29033
    I've been a developer since 2009 and I've learnt a lot of languages since, but I've always wanted to understand and be able to code in the lowest level language so I can directly (or at least very close to directly) speak to machines through my code. There was a point in time when someone showed me how to do an if statement in assembly, but out of all the books that I got, I could never really understand where/how to start learning to code in assembler. any help please? I'm obsessed with learning this! PS: if you have any software suggestions, I use ubuntu and am looking to convert to backtrack soon, so it would be preferred if you could give me something that'll be easily installed on debian linux, otherwise don't sweat it, give me the name of the windows software and I'll find an equivalent myself

  • Java 7 Adoption at 79%

    - by Henrik Stahl
    According to a recent blog post from the cloud hosting company Jelastic, Java 7 adoption on their platform is now at 79%. While this is a single data point and should not be read too broadly, it does match other indicators we have that Java 7 is picking up, such as uptake among Oracle middleware customers, download statistics and online activity. The spike in adoption in April coincided with the release of JDK 7 Update 4. This is in line with our expectations since that release added Mac OS X support as well as java.com moving to Java 7 as the default download for end-users; two events that marked the maturity of Java 7 to the community. Since the original release of Java 7, Oracle has shipped 7 update releases, added ports to Mac OSX and Linux/ARM and expanded JavaFX to all common desktop platforms.

  • samba "username map" stopped to work after upgrade to 3.6

    - by Kris_R
    It was time to upgrade our group server (new HDs, problems with old installation of DRBD, etc..). Going as usually for CentOS i upgraded whole system from 6.3 to 6.4 The later one came with samba 3.6 as the old one was 3.5. I transferred most of users by copying /etc/password, /etc/shadow and samba accounts with pdbedit. Homes were on nfs-drive. The translation of unix accounts to samba accounts are located in /etc/samba/smbusers. Strangely enough on some windows clients there was problem to connect to samba-shares. In one case the only thing that worked was, instead of giving windows name, to use the unix account. In another one, it was possible to mount network drive and to open it in Windows Explorer, however other applications like "Total commander" at the attempt of opening this drive gave the message "Cannot connect to z:" (sometimes at this moment user/pass were requested). The smb.conf has following entries: [global] security = user passdb backend = tdbsam username map = /etc/samba/smbusers ... [Kris] comment = Kris's Private path = /SMB/Users/Kris writeable = yes read only = no browseable = yes users = krisr printable = no security mask = 0777 force security mode = 0 directory security mask = 0777 force directory security mode = 0 force create mode = 0775 force directory mode = 6775 The smbusers: # Unix_name = SMB_name1 SMB_name2 ... krisr = Kris Of course testparm runs without any errors. I was used from samba 3.5 to outputs of form Mapped user kris to krisr. Nothing like this happens now. Just message check_sam_security: Couldn't find user Kris in passdb. I read on web that some guys had problem with 3.6 and security = ADS, but these were not helpful for me. I'm seriously thinking about downgrading back to samba 3.5 but before this step I wanted to ask if somebody knows the solution of these problems.
