• What changed with timidity, alsa and jack in 11.10?

  - by Dave

  I (just) upgraded from 11.4 to 11.10 and noticed some differences in the behavior of timidity. I used to (11.4) exectute >timidity midifile.midi without running jackd, and thus using alsa (or pulseaudio?) to produce sound from midi files. Now having upgraded, this does not work -- currently this command just freezes if jack is not running. If jack is running, it does work but there is an initial audio glitch (noise burst at the start of playback, analogous to the sound of a plug being inserted) that I'd rather not have to deal with. All the indications that I have is that in 11.10 timidity will only work (albeit glitchy) with jack on, whereas in 11.4 it did not require this. Is there any way to restore timidity's non-jack operation in 11.10? Is there a way to get rid of the audio glitch in with jack operation? Overall, what underlying changes in these programs and the audio infrastructure are behind this?

• How do you fix "failed command: IDENTIFY DEVICE" showing up in dmesg?

  - by Neil

  I just got a new Mushkin 60gb SSD, and it's now my primary drive in the ata1 spot. I've been getting these failed command: IDENTIFY DEVICE errors which are preventing rebooting and shutdown. Does anyone know what these could be caused by, or how to start troubleshooting? I've tried these kernels: 2.6.32-22-generic 2.6.31-17-generic And they both have the same error. Here is a link to my entire dmesg. And the relevant ata1.00 parts below: [ 59.804237] ata1: drained 256 bytes to clear DRQ.

• Developing a long pannable, sprite-animated Windows Store app

  - by Groo

  I am creating my first Windows Store app in XAML, and I cannot seem to find a proper example for the requirements I have (I have spent a couple of days fiddling around, so I apologize if I missed something obvious). Basic idea of the app is to have a large scrollable canvas which would lazily start animating visible parts of the view as soon as user stops panning over a certain content (with some audio played also): My original idea was to use a StackPanel to add a bunch of custom controls, each of which would then animate itself once visible (with a short delay), but I have a couple of concerns: If the entire canvas is ~50 screen widths wide, is it feasible to load all content at the beginning, or do I need to plan doing some lazy loading during scrolling? For example, when I select a certain region in the Bing Travel app, it seems to lazily load tiles as I scroll it towards the end. Since content is stretched 100% vertically, and these animations are vectorized to be resolution independent, I am not sure if XAML (CompositionTarget) will be able to handle this, or I have to go for DirectX (MonoGame or C++) to get rid of flicker. Even better, is there an example for Windows 8 which uses a 100% vertically sized GridView with custom animated controls inside?

• Improving SpriteBatch performance for tiles

  - by Richard Rast

  I realize this is a variation on what has got to be a common question, but after reading several (good answers) I'm no closer to a solution here. So here's my situation: I'm making a 2D game which has (among some other things) a tiled world, and so, drawing this world implies drawing a jillion tiles each frame (depending on resolution: it's roughly a 64x32 tile with some transparency). Now I want the user to be able to maximize the game (or fullscreen mode, actually, as its a bit more efficient) and instead of scaling textures (bleagh) this will just allow lots and lots of tiles to be shown at once. Which is great! But it turns out this makes upward of 2000 tiles on the screen each time, and this is framerate-limiting (I've commented out enough other parts of the game to make sure this is the bottleneck). It gets worse if I use multiple source rectangles on the same texture (I use a tilesheet; I believe changing textures entirely makes things worse), or if you tint the tiles, or whatever. So, the general question is this: What are some general methods for improving the drawing of thousands of repetitive sprites? Answers pertaining to XNA's SpriteBatch would be helpful but I'm equally happy with general theory. Also, any tricks pertaining to this situation in particular (drawing a tiled world efficiently) are also welcome. I really do want to draw all of them, though, and I need the SpriteMode.BackToFront to be active, because

• Reverse rdesktop or VNC overlay image!

  - by carlesso

  Hi all. I've got a central server (linux based) and many clients (Windows XP Embedded, afaik) in public places around my country. I need to have these clients to connect to the server with a "reverse" tunnel, that is to say that I need to control the clients from the server but the connection is initialized by clients. The requirement is that, during the connection, an overlay image (or something like that, like a modified version of login screen) is displayed. Some stuff like "Work In Progress". My first idea was to use vncviewer -listen and vnc in reverse mode, but cannot understand how to obfuscate the work I'm doing. Other idea was to use rdesktop in "reverse" mode, but it seems it does not support it. Using rdekstop reverse seems the nicest solution (I can login back the user was in before connection, the login manager - which I can modified - is displayed), but any hint will be appreciated! Thanks in advance!

• Were you a good programmer when you first left university?

  - by dustyprogrammer

  I recently graduated, from university. I have since then joined a development team where I am by far the least experienced developer, with maybe with a couple work terms under my belt, meanwhile the rest of the team is rocking 5-10 years experience. I am/was a very good student and a pretty good programmer when it came to bottled assignments and tests. I have worked on some projects with success. But now I working with a much bigger code-base, and the learning curve is much higher... I was wondering how many other developers started out their careers in teams and left like they sucked. When does this change? How can I speed up the process? My seniors are helping me but I want to be great and show my value now. I don't to start a flame war, this is just a question I have been having and I was hoping to get some advice from other experienced developers, as well as other beginners like me.

  Start with definitions: Yellow: Satisfactory. You could make some further improvements to this item. I have few sites using Google AdSense to make cents (yes, cents only). On recent update of Google AdSense, a new module called Scorecard displayed on my dashboard. In item Revenue optimization Text and image ads enabled , it is marked as Yellow. But I have already enabled Text and Image ads in all my sites. Why does it still having Yellow instead of Green? Is it a bug of Google AdSense Scorecard ?

• How to achieve highly accurate car physics such as Liveforspeed?

  - by Kim Jong Woo

  Liveforspeed is a racing simulator, there is amazing amount of realistic physics. for example, tires get warm, tire actually deforms when you turn corners. You need to play this game with a mouse at the minimum because it almost drives like the real thing. Anyhow, how does one achieve that level of physics simulation? Are there off-the-shelf solutions out there? If not, how does one start with simulating real world physics as close as possible. I would love to be able to work on an opensource car physics focused game. Imagine, more passionate developers, it could keep things going.

• Python script liking to GUI using IDE

  - by YomalSamindu

  I am studying python. Now I can write python scripts (codes) to some extent. I used IDLE for this. I am interested in making GUI to those written programs. I like to do it using an IDE rather than using PyGTK or Tkinter. Can anyone help me how to start with this and link my scripts to a GUI? I downloaded a IDE called glade, but I don't know how to use this IDE. I need some tutorial guide also. Can anyone help me, please? Thank you!

• QotD - Nicolas de Loof on AdoptOpenJDK

  - by $utils.escapeXML($entry.author)

  The AdoptOpenJDK program is an initiative to get as many Java users as possible to try the OpenJDK 8 preview builds, so that feedback is collected before JDK 8 is officially released. There are many ways to contribute to this program (as explained on the wiki), but the most basic one is to start testing your own project on the Java 8 platform. CloudBees can help you there, as we just made OpenJDK 8 (preview) available on DEV@cloud so that you can configure a build job to check project compatibility. We will upgrade the JDK for all recent preview builds until JDK 8 is finalNicolas de Loof, Support Engineer at Cloudbees in a blog post on AdoptOpenJDK.

• Which logs will tell me about the Touchpad and Keyboard locking up?

  - by Sepero

  I have an Asus N53SM laptop that I leave running for several weeks at a time. I never put it in hibernate or suspend, I only close the lid when I'm not using it. After a few days or weeks of running, the touchpad and keyboard will Both lock up (at the same time) for no apparent reason. I could be just surfing the internet when it happens. The touchpad and keyboard seem to only lock up when I'm actively using the laptop (not when idle), which may mean it's related to something I press, but I'm not sure? The touchpad never locks or unlocks when Pressing FN and the designated touchpad lock key (it does not seem to work on Linux). While the touchpad and keyboard are locked, I am able to plug in my USB mouse and successfully use it to control the screen cursor. I can also remotely get into the system with vnc and ssh, everything seems to run fine there as well. No processes appear out of control. It's just the laptops physical touchpad and keyboard that are locking up. How might I go about diagnosing this problem? What system logs to look at? (anything specific to look for in them?) Perhaps I should try reloading some modules? Any thing else I should inspect?

• Live from ODTUG - Big Data and SQL session #2

  - by Jean-Pierre Dijcks

  Sitting in Dominic Delmolino's session at ODTUG (KScope 12). If the session count at conferences is any indication then we will see more and more people start to deploy MapReduce in the database. And yes, that would be with SQL and PL/SQL first and foremost. Both Dominic and our own Bryn Llewellyn are doing MapReduce in the database presentations.  Since I have seen both, I would advice people to first look through Dominic's session to get a good grasp on what mappers do and what reducers do, then dive into Bryn's for a bunch of PL/SQL example. The thing I like about Dominic's is the last slide (a recursive WITH statement) to do this in SQL... Now I am hoping that next year we will see tools vendors show off how they work with Hadoop and MapReduce (at least talking about the concepts!!).

• Dual-headed graphics card choice: DVI & VGA with 512MB _or_ DVI & DVI with 256MB

  - by TimH

  Which would you choose? Some more detail: I can choose between: A dual-headed card with both heads DVI but only 256MB of memory A dual-headed card with one VGA and one DVI, with 512MB of memory. Both monitors are 1600x1200 I'll be doing mostly business app development on the computer. No gameplay or advanced graphics work. It's running Win7 and is a quad-core i5. I'm thinking of going with 256MB one, just so both displays are DVI and I don't have to shift between sharp & blurry when I look from one screen to the other. But I'm not sure if the additional RAM would be a huge boon for some reason (Win7 GPU acceleration, for example? But with a quad-core, who cares?).

• Restore Windows 7 bootloader after Windows 8 install

  - by JMK

  I have installed Windows 8 onto a partition after Windows 7, and when I turn my PC on, Windows 8 basically loads completely, and then I get the option to choose my OS. If I select Windows 8, I go straight to the lock screen, if I select Windows 7, my computer completely restarts and then boots into 7. I want to use the Windows 7 installation DVD to restore the Windows 7 bootloader using the method described by the How To Geek but I am worried that if I do this, Windows 8 won't boot. Can anybody advise on whether or not this will work, and if not how can I go back to selecting the OS right after the BIOS loads?

• MOSS 2010 Deploy Farm Solution using STSADM

  - by H(at)Ni

  Today, I've been working on deploying farm solutions to another farm and I was surprised that it can only be done using STSADM.exe. Below are the steps that I've done to get it to work : 1. Use the command addsolution  and give it the path of the wsp file which was something like that : stsadm -o addsolution -filename C:\MySolution.wsp 2. Use the command deploysolution and give the solution name as a parameter like that : stsadm -o deploysolution -name MySolution.wsp -immediate -allowgacdeployment If then you encountered an error saying : The timer job for this operation has been created, but it will fail because the administrative service for this server is not enabled. If the timer job is sched uled to run at a later time, you can run the jobs all at once using stsadm.exe - o execadmsvcjobs. To avoid this problem in the future, enable the Microsoft Shar ePoint Foundation administrative service, or run your operation through the STSA DM.exe command line utility. then use the following command to enforce the execution of your deployment: Start-SPAdminJob And that's it, you'll have it working as expected :)

• Ubuntu won't boot, only displays GRUB terminal

  I have a problem with my Ubuntu 11.04. I've installed Ubuntu 11.04 from Windows, it worked fine for days, but today it won't boot. When I start the machine, GRUB loads. There is the Windows 7 loader, I select Ubuntu from there and after that, I should see the Ubuntu GRUB menu, where I'd select the mode to boot Ubuntu. However, I can't see that anymore. I directly get to a GRUB terminal. Can anyone help me with this? How would I recover my data or reset the boot loader?

• Memory Efficient Windows SOA Server

  - by Antony Reynolds

  Installing a Memory Efficient SOA Suite 11.1.1.6 on Windows Server Well 11.1.1.6 is now available for download so I thought I would build a Windows Server environment to run it.  I will minimize the memory footprint of the installation by putting all functionality into the Admin Server of the SOA Suite domain. Required Software 64-bit JDK SOA Suite If you want 64-bit then choose “Generic” rather than “Microsoft Windows 32bit JVM” or “Linux 32bit JVM” This has links to all the required software. If you choose “Generic” then the Repository Creation Utility link does not show, you still need this so change the platform to “Microsoft Windows 32bit JVM” or “Linux 32bit JVM” to get the software. Similarly if you need a database then you need to change the platform to get the link to XE for Windows or Linux. If possible I recommend installing a 64-bit JDK as this allows you to assign more memory to individual JVMs. Windows XE will work, but it is better if you can use a full Oracle database because of the limitations on XE that sometimes cause it to run out of space with large or multiple SOA deployments. Installation Steps The following flow chart outlines the steps required in installing and configuring SOA Suite. The steps in the diagram are explained below. 64-bit? Is a 64-bit installation required?  The Windows & Linux installers will install 32-bit versions of the Sun JDK and JRockit.  A separate JDK must be installed for 64-bit. Install 64-bit JDK The 64-bit JDK can be either Hotspot or JRockit.  You can choose either JDK 1.7 or 1.6. Install WebLogic If you are using 64-bit then install WebLogic using “java –jar wls1036_generic.jar”.  Make sure you include Coherence in the installation, the easiest way to do this is to accept the “Typical” installation. SOA Suite Required? If you are not installing SOA Suite then you can jump straight ahead and create a WebLogic domain. Install SOA Suite Run the SOA Suite installer and point it at the existing Middleware Home created for WebLogic.  Note to run the SOA installer on Windows the user must have admin privileges.  I also found that on Windows Server 2008R2 I had to start the installer from a command prompt with administrative privileges, granting it privileges when it ran caused it to ignore the jreLoc parameter. Database Available? Do you have access to a database into which you can install the SOA schema.  SOA Suite requires access to an Oracle database (it is supported on other databases but I would always use an oracle database). Install Database I use an 11gR2 Oracle database to avoid XE limitations.  Make sure that you set the database character set to be unicode (AL32UTF8).  I also disabled the new security settings because they get in the way for a developer database.  Don’t forget to check that number of processes is at least 150 and number of sessions is not set, or is set to at least 200 (in the DB init parameters). Run RCU The SOA Suite database schemas are created by running the Repository Creation Utility.  Install the “SOA and BPM Infrastructure” component to support SOA Suite.  If you keep the schema prefix as “DEV” then the config wizard is easier to complete. Run Config Wizard The Config wizard creates the domain which hosts the WebLogic server instances.  To get a minimum footprint SOA installation choose the “Oracle Enterprise Manager” and “Oracle SOA Suite for developers” products.  All other required products will be automatically selected. The “for developers” installs target the appropriate components at the AdminServer rather than creating a separate managed server to house them.  This reduces the number of JVMs required to run the system and hence the amount of memory required.  This is not suitable for anything other than a developer environment as it mixes the admin and runtime functions together in a single server.  It also takes a long time to load all the required modules, making start up a slow process. If it exists I would recommend running the config wizard found in the “oracle_common/common/bin” directory under the middleware home.  This should have access to all the templates, including SOA. If you also want to run BAM in the same JVM as everything else then you need to “Select Optional Configuration” for “Managed Servers, Clusters and Machines”. To target BAM at the AdminServer delete the “bam_server1” managed server that is created by default.  This will result in BAM being targeted at the AdminServer. Installation Issues I had a few problems when I came to test everything in my mega-JVM. Following applications were not targeted and so I needed to target them at the AdminServer: b2bui composer Healthcare UI FMW Welcome Page Application (11.1.0.0.0) How Memory Efficient is It? On a Windows 2008R2 Server running under VirtualBox I was able to bring up both the 11gR2 database and SOA/BPM/BAM in 3G memory.  I allocated a minimum 512M to the PermGen and a minimum of 1.5G for the heap.  The setting from setSOADomainEnv are shown below: set DEFAULT_MEM_ARGS=-Xms1536m -Xmx2048m set PORT_MEM_ARGS=-Xms1536m -Xmx2048m set DEFAULT_MEM_ARGS=%DEFAULT_MEM_ARGS% -XX:PermSize=512m -XX:MaxPermSize=768m set PORT_MEM_ARGS=%PORT_MEM_ARGS% -XX:PermSize=512m -XX:MaxPermSize=768m I arrived at these numbers by monitoring JVM memory usage in JConsole. Task Manager showed total system memory usage at 2.9G – just below the 3G I allocated to the VM. Performance is not stellar but it runs and I could run JDeveloper alongside it on my 8G laptop, so in that sense it was a result!

  - by Adam

  I'm trying to get some control over the brightness of my Samsung QX411 (Integrated Intel and discrete Nvidia, though Ubuntu doesn't see the latter yet, I'll play around with Bumblebee later) Using the FN+up/down lowers the screen brightness from max to one peg down or back up. If I try to bring the brightness down any more, it just flickers and stays the same. I can lower the brightness in Settings, but that's delicate and gets reverted to max if I open up the brightness settings again, or log out. The closest I got was adding acpi_backlight=vendor to a line in /etc/default/grub, (source) I could consequently lower the brightness a couple of pegs down to the minimum with FN+down, but then it's as if the problem got inversed, and I'd get stuck in the bottom tier, I could only increase the brightness by one peg and back down. Rebooting would revert to max brightness. acpi_osi=, acpi_osi=Linux, acpi_osi=vendor, acpi_osi='!Windows 2012', acpi_backlight=Linux, acpi_backlight='!Windows 2012' don't do anything for me. I've also tried adding echo 2000 > /sys/class/backlight/intel_backlight/brightness to /etc/rc.local, where my max value from cat /sys/class/backlight/intel_backlight/brightness is 4648, which didn't do anything. (same result with echo 2000 > /sys/class/backlight/acpi_video0/brightness) source Samsung tools also didn't help in this regard. I've spent hours on this, it's getting quite frustrating. Any help would be greatly appreciated.

• My IPSec VPN isn't allowing me to connect

  - by jbondhus

  I'm following this guide to create an IPsec VPN on a debian server. I followed all the steps, and it still isn't working. If I try connecting to it, I get an error. I've looked for the logs, but I'm not sure where they would be put, other than /var/logs. I aim to be able to browse the internet from my home connection, and access my home network as if it is my local network (eg. access my home fileserver and printers, and screen share my home computers remotely without a complicated port forwarding setup.

• how to package a unity lens app

  - by Asim

  i'm new to ubuntu apps and launchpad. I've created a unity lenses app using quickly but i'm stuck on how to deploy it, i have two questions. I can create a deb file using quickly package but when i install it, i still need to manually restart unity and run the project using 'quickly run'. how can i get the package manager to do that on install so users can start using the lens straight away? I'm confused as to what i need to do to make my project be installed using a ppa. i've pushed my code to launchpad using bzr, i've created a ppa, openpgp key, ssh etc. i don't know what to do next? Any help would be appreciated. My project in launchpad is unity-lens-php Thanks

• powertop keeps telling me to turn off the same thing, over and over

  - by Rory McCann

  I am running an ubuntu lucid laptop on battery. I want to make my power last as long as possible. Aswell as the normal things like turn down screen brightness, and turn off wifi, I'm using powertop. It will sometimes tell me things, e.g.: Suggestion: Enable USB autosuspend by pressing the U key OK, I press the U key to do that. However a few minutes later it will give me the same suggestion, it's as if it never enabled USB autosuspend the first time. It does this for other things aswell, not just USB autosuspend. e.g. it'll give me this message frequently: An audio device is active 100.0% of the time: hwC0D1 LSI ID 1040 Q - Quit R - Refresh A - Turn HD audio powersave on Is there anything I can do to make these choices 'stick'? Or do I have some unfortunatle hardware that won't obey linux? (If so, is there any way to confirm this?)
