• 12.04.1 no audio through HDMI

  - by JoJo

  having a bit of an issue with getting audio to go through HDMI. Here are the base specs: OS: Ubuntu Desktop 12.04.1 x64 CPU: AMD A10-5800K 3.8G 4M FM2 R Mobo: MSI FM2-A75MA-E35 OS: Ubuntu 12.04.1 LTS Vid Card: (integrated on CPU) AMD Radeon HD 7660D HDMI sound works fine under Win7 (after mobo and vid drivers are installed), so it's not physically broken. Audio through the normal headphone jacks works fine under Ubuntu. Looking at the audio panel, there is no HDMI output at all. aplay -l also reports only: card 0: Generic [HD-Audio Generic], device 0: ALC887-VD Analog [ALC887-VD Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 In additional drivers there are two versions: ATI/AMD PROPRIETARY FGLRX GRAPHICS DRIVER ATI/AMD PROPRIETARY FGLRX GRAPHICS DRIVER (post-release update) The first installs, but problem persists. I do get more resolutions to pick from. Second version does not, reporting it failed installation and to find details at: /var/log/jockey.log Looked at the log, and it's insanely long, if necessary I can get it to you guys. Did more research and some had luck by manually installing the drivers, so tried to give that a shot by following this: https://help.ubuntu.com/community/BinaryDriverHowto/ATI#Manually_installing_Catalyst_12.6 starting at 3.1 Manually installing Catalyst 12.6. I immediately had 2 issues, (1) the AMD website does not provide any drivers for Linux, and (2) the following command did not work: sudo sh amd-driver-installer-12-6-x86.x86_64.run --buildpkg Ubuntu/precise sh: 0: Can't open amd-driver-installer-12-6-x86.x86_64.run Some other posts stated to update "alsa-drivers", but that also did not work as install command for the new version of them did not work. I forget the exact issue, but similar to above, cannot open / cannot find. Any help would be greatly appreciated!

• MVVM - child windows and data contexts

  - by GlenH7

  Should a child window have it's own data context (View-Model) or use the data context of the parent? More broadly, should each View have its own View-Model? Are there are any rules to guide making that decision? What if the various View-Models will be accessing the same Model? I haven't been able to find any consistent guidance on my question. The MS definition of MVVM appears to be silent on child windows. For one example, I have created a warning message notification View. It really didn't need a data context since it was passed the message to display. But if I needed to fancy it up a bit, I would have tapped the parent's data context. I have run into another scenario that needs a child window and is more complicated than the notification box. The parent's View-Model is already getting cluttered, so I had planned on generating a dedicated VM for the child window. But I can't find any guidance on whether this is a good idea or what the potential consequences may be. FWIW, I happen to be working in Silverlight, but I don't know that this question is strictly a Silverlight issue.

• Message Queue: Which one is the best scenario?

  - by pandaforme

  I write a web crawler. The crawler has 2 steps: get a html page then parse the page I want to use message queue to improve performance and throughput. I think 2 scenarios: scenario 1: structure: urlProducer -> queue1 -> urlConsumer -> queue2 -> parserConsumer urlProducer: get a target url and add it to queue1 urlConsumer: according to the job info, get the html page and add it to queue2 parserConsumer: according to the job info, parse the page scenario 2: structure: urlProducer -> queue1 -> urlConsumer parserProducer-> queue2 -> parserConsumer urlProducer : get a target url and add it to queue1 urlConsumer: according to the job info, get the html page and write it to db parserProducer: get the html page from db and add it to queue2 parserConsumer: according to the job info, parse the page There are multiple producers or consumers in each structure. scenario1 likes a chaining call. It's difficult to find the point of problem, when occurring errors. scenario2 decouples queue1 and queue2. It's easy to find the point of problem, when occurring errors. I'm not sure the notion is correct. Which one is the best scenario? Or other scenarios? Thanks~

• Examples of limitations in IT due to different bit length by design

  - by Alaudo

  I am teaching the course "Introduction in Programming" for the first-year students and would like to find interesting examples where the datatype size in bits, chosen by design, led to certain known restrictions or important values. Here are some examples: Due to the fact that the Bell teleprinter used 7-bit-code (later accepted as ASCII) until now have we often to encode attachments in electronic messages to contain only 7 bit data. Classical limitation of 32-bit address space leads to the 4Gb maximal RAM size available for 32-bit systems and 4Gb maximal file size in FAT32. Do you know some other interesting examples how the choice of the data type (and especially its binary length) influenced the modern IT world. Added after some discussion in comments: I am not going to teach how to overcome limitations. I just want them to know that 1 byte can hold the values from -127..0..+127 o 0..255, 2 bytes cover the range 0..65535 etc by proving examples they know from other sources, like the above-mentioned base64 encoding etc. We are just learning the basic datatypes and I am trying to find a good reference for "how large" these types are.

• Are very short or abbreviated method/function names that don't use full words bad practice or a matter of style.

  - by Alb

  Is there nowadays any case for brevity over clarity with method names? Tonight I came across the Python method repr() which seems like a bad name for a method to me. It's not an English word. It apparently is an abbreviation of 'representation' and even if you can deduce that, it still doesn't tell you what the method does. A good method name is subjective to a certain degree, but I had assumed that modern best practices agreed that names should be at least full words and descriptive enough to reveal enough about the method that you would easily find one when looking for it. Method names made from words help let your code read like English. repr() seems to have no advantages as a name other than being short and IDE auto-complete makes this a non-issue. An additional reason given in an answer is that python names are brief so that you can do many things on one line. Surely the better way is to just extract the many things to their own function, and repeat until lines are not too long. Are these just a hangover from the unix way of doing things? Commands with names like ls, rm, ps and du (if you could call those names) were hard to find and hard to remember. I know that the everyday usage of commands such as these is different than methods in code so the matter of whether those are bad names is a different matter.

• Tips for switching jobs and moving into web based programming?

  - by JerryC

  I graduated in 2006 with a computer science degree and got solid grades (3.5 overall 3.8 in my major) For the past 4.5 years I've been working as a Software Engineer doing primarily rich client development. Most of my experience is with Java, Swing and C++. I've done a lot of network programming and I have acquired some skill working & debugging in distributed environments. I would like to switch jobs and move into a role where I can get exposure to some new technologies and frameworks. I would like to move into a more web development role but I find my lack of web development experience is hurting me. 90% of the jobs I see advertised are looking for one of two skill sets: 1) Stereotypical server side Java web developer. Experience with Spring, Hibernate, J2EE, etc. 2) Stereotypical front end web developer. Experience with Javascript, jQuery, HTML5, GWT, CSS, etc I find most of these companies are looking really specifically for this experience and they are not willing to take on good programmers/ CS fundamental guys who lack experience with this stuff. I would love to get a job doing stuff like this, but have my skills become out of date and unmarketable? Any opinions on ways to sell myself to help get a new position?

• Going to UKOUG in December? Meet the Fusion User Experience Advocates

  - by mvaughan

  By Misha Vaughan, Oracle Applications User Experience The Oracle Fusion User Experience Advocates (FXA) will be hosting a roundtable event at UKOUG in December. The FXA program is run by me and Andrew Gilmour, my co-host and fellow team member from the Oracle Applications User Experience group. At this event, our Advocates will be doing the talking -- or rather, answering your questions. If you come to the roundtable, you will find out that the FXA members are a subset of Oracle ACE Directors who have taken on a commitment to participate in deep-dive training on the Oracle Fusion Applications User Experience, and then blend that training into their own areas of expertise – be it applications, Fusion Middleware, or SOA. The Advocates then make themselves available to local special-interest groups and geographic interest groups for public-speaking events, bringing with them a piece of the Fusion Applications user experience story – including demos. Come to the roundtable for a chance to chat with Andrew and me, but more importantly, take this opportunity to meet some of the Advocates firsthand and find out what they can offer to you and your professional group. For more information on the events and presentations that the Applications User Experience team will take part in at UKOUG, visit our Usable Apps Events page.

• Steam on 64-bit 14.04: need some help, missing a few 32-bit libs

  - by YellowShark

  Steam says I'm missing the following libs, I'm hoping someone can help me get things in better shape: xyz@abc:~$ STEAM_RUNTIME=0 steam Running Steam on ubuntu 14.04 64-bit STEAM_RUNTIME is disabled by the user Error: You are missing the following 32-bit libraries, and Steam may not run: libpangoft2-1.0.so.0 libpango-1.0.so.0 libgtk-x11-2.0.so.0 libgdk_pixbuf-2.0.so.0 Installing breakpad exception handler for appid(steam)/version(1401381906_client) Installing breakpad exception handler for appid(steam)/version(1401381906_client) [2014-06-11 20:45:39] Startup - updater built May 29 2014 09:19:23 [2014-06-11 20:45:39] Verifying installation... [2014-06-11 20:45:39] Verification complete [2014-06-11 20:45:42] Shutdown I tried installing the following i386 packages: libpango-1.0-0:i386, libpangoft2-1.0-0:i386, and libgdk-pixbuf2.0-0:i386, and symlinking the .so files (from usr/lib/i386whatever../) into the ~/.local/share/Steam/ubuntu12_32/ folder, but wasn't able to find the right match for the gtk-x11 lib, and ultimately would up with a different, but still non-working situation. So I've back-tracked to this point, and have removed those i386 packages for now. It's worth noting thatSteam runs if I don't use STEAM_RUNTIME=0. Also, Steam seemed to "recognize" the i386 version of the libpango & libpangoft2 libs after I symlinked them into place, during the course of my troubleshooting; when I would rerun STEAM_RUNTIME=0 steam, it wouldn't list those two items as missing anymore. Instead though, I had a bunch of gtk-related issues, something about overlay-scrollbar not available, as well as warnings that it can't find the murrine engine... a whole bunch of stuff that sounded like I'd gone too far down the wrong path. Anyhow, any help sorting this out would be appreciated, and thanks!

• I cannot solve the "Install these packages without verification" problem

  - by Yonatan Orlev

  I Googled and Googled and I just cannot find a solution to this problem: sudo apt-get install <whatever> Gives me: WARNING: The following packages cannot be authenticated! and Install these packages without verification [y/N]? I cannot find a decent solution. The closest I got was to run: sudo apt-get install debian-keyring debian-archive-keyring But then, even thought, and against my good judgment I agreed to install the package without confirmation, I get: (I replaced http with XXXX because of forum limitations). Install these packages without verification [y/N]? y Err XXXX://il.archive.ubuntu.com gutsy/universe debian-archive-keyring 2007.02.19-0.1 404 Not Found Err XXXX://il.archive.ubuntu.com gutsy/universe debian-keyring 2005.05.28 404 Not Found Failed to fetch XXXX://il.archive.ubuntu.com/ubuntu/pool/universe/d/debian-archive-keyring/debian-archive-keyring_2007.02.19-0.1_all.deb 404 Not Found Failed to fetch XXXX://il.archive.ubuntu.com/ubuntu/pool/universe/d/debian-keyring/debian-keyring_2005.05.28_all.deb 404 Not Found E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? Trying to run apt-get update also does not help: I get tons of "404 Not Found" errors. Can someone please direct me to a good solution to this problem? I cannot understand why this issue is not better documented. There must be a simple solution which allows me to update my list of sources or whatever.

• Looking for a simple web interface with subversion support and ticket /issue tracker [closed]

  - by Stefan Andre Brannfjell

  I am working on a small project and we have a few programmers on the job. We are using subversion to commit updates and keep all developers up to date on their workstations. However, we have yet to find a suitable web interface to use for it. I have tried redmine, but that installation progress was extremely bothersome and advanced. Once I got it to work I found out that it was slow and did not meet my expectations. As well as it seems a bit complex for our needs. I would prefer to find a solution that supports lighttpd web server, however that seem to be very hard to come by, those I have found seem to only have apache support. Functionality i wish for the website: - login to an svn account - view svn logs - view & create issues, todo list etc - view svn difference Do you have any open source recommendations that I can try out? I will appreciate any kind of reply. :) Edit: I wish to host the website on our own servers.

• Subsumption architecture vs. perceptual control theory

  - by Yasir G.

  I'm a new person to AI field and I have to research and compare 2 different architectures for a thesis I'm writing. Before you scream (homework thread), I've been reading on these 2 topics only to find that I'm confusing myself more.. let me first start with stating briefly what I know so far. Subsumption is based on the fact that targets of a system are different in sophistication, thus that requires them to be added as layers, each layer can suppress (modify) the command of the layers below it, and there are inhibitors to stop signals from execution lets say. PCT stresses on the fact that there are nodes to handle environmental changes (negative feedback), so the inputs coming from an environment go through a comparator node and then an action is generated by that node, HPCT or (Hierarchical PCT) is based on nesting these cycles inside each other so a small cycle to avoid crashing would be nested in a more sophisticated cycle that targets a certain location for example. My questions, am I getting this the right way? am I missing any critical understanding about these 2 models? also any idea where I can find simplified explanations for each theory (so far been struggling trying to understand the papers from Google scholar :< ) /Y

• Integrating with Oracle Fusion Applications: Discovering Integration Artifacts

  - by Lionel Dubreuil

  Oracle Enterprise Repository serves as the core element to the Oracle SOA Governance solution. An industry-leading metadata repository, Oracle Enterprise Repository provides a solid foundation for delivering governance throughout the service-oriented architecture (SOA) lifecycle by acting as the single source of truth for information surrounding SOA assets and their dependencies. For Fusion Applications, the use of OER has been extended to include other integration asset types such as interface tables and other technical information such as data models, tables, views, lookups, profile options, et cetera. E-Business Suite users familiar with iRepository or eTRM will recognize the functionality in Fusion Applications OER. Oracle Enterprise Repository for Fusion Applications provides a common catalog of technical information, searchable using many different mechanisms. Customers can locate technical information by the name, description or keyword of the information they are looking for. They can also search by the type of asset they are trying to locate and/or where the asset sits in the product taxonomy. They can also see the how the asset dances in the choreography of some illustrative co-existence scenarios. These scenarios are laid out as both functional flow diagrams as well as technical interaction diagrams. Rajesh Raheja, software architect at Oracle, has recently posted an article on this topic: visibility and control are the key tenets to SOA governance, and the first step in integrating with Oracle Fusion Applications is to find out what are the integration options available. Oracle Enterprise Repository, an industry-leading metadata repository, provides this visibility. You can find his full blog post here.

• Project Codenames - Yea or Nay?

  - by rmx

  Where I work, most of our projects have (or at least attempt) descriptive, useful names. However we have a few with names that make no sense: I found that an assembly named WiFi which actually has nothing whatsoever to do with wi-fi, but is a codename. When I asked why, I was told that it's to protect company secrets incase some intern has few too many at the pub on Friday and starts chatting about the brand new 'WiFi' project he's been working on. Its clear that some people find enjoyment in finding silly / amusing codenames for their projects (like in this question). My question is: is it really a good idea to use codenames for your projects or are you better off spending the time to decide upon a descriptive name? My opinion is that in the long-run its better to give your projects relevant names. My reasoning is that if you can't think of a decent name, perhaps you don't really know the requirements well enough. I think there are better ways to 'protect company secrets' and I find it quite confusing when the name does not correlate at all with the content. It's just common sense, surely?! So do you use codenames and what the your reasons for or against this seemingly common, yet annoying (to me at least) practice?

• How can I install Celtx 2.9.7 properly on Ubuntu 12.04 LTS?

  - by cruxfilm

  I am new to Ubuntu and Linux and I want to install and use the newest version of the screenwriting software Celtx on Ubuntu 12.04 LTS. After trying https://answers.launchpad.net/ubuntu/+source/ubiquity/+question/206295 and using sudo add-apt-repository ppa:dreamstudio/video sudo apt-get update sudo apt-get install celtx I unfortunately had to find out that was a rather old version with a fairly screwed up UI. I then downloaded the newest version from http://download.celtx.com/2.9.7/Celtx-2.9.7-64.tar.bz2 but now I don't know how to properly install it. I extracted it to /home/username/ (there was no ~/bin/) as described here and I can now launch the application by running the file celtx within that folder (I get asked whether I want to Display, run or run it in Terminal) and it works fine. But I can't get it to launch from Unity. I tried right-clicking the launcher button and going "Lock to Launcher" while it's running and it does create an icon but clicking it to launch the program does nothing. Also searching for celtx in the Dash doesn't find the app. And advice on how to properly install Celtx 2.9.7 in Ubuntu 12.04 LTS?

• Unavailable packages repository

  I'm running ubuntu 11.10 (oneiric) on this machine, and suddenly, apt is unable to update properly. If I ask it to update its package information, by running apt-get update (or alternatively telling the update manager to "check"), it succeeds for about 120 packages (more precisely, I get about 120 Ign/Hit notes) and then says it cannot find universe Sources and restricted amd64: Hit http://de.archive.ubuntu.com oneiric-backports/multiverse Translation-en Hit http://de.archive.ubuntu.com oneiric-backports/restricted Translation-en Hit http://de.archive.ubuntu.com oneiric-backports/universe Translation-en Err http://de.archive.ubuntu.com oneiric/universe Sources 404 Not Found [IP: 141.30.13.20 80] Err http://de.archive.ubuntu.com oneiric/restricted amd64 Packages 404 Not Found [IP: 141.30.13.20 80] W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/oneiric/universe/source/Sources 404 Not Found [IP: 141.30.13.20 80] W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/oneiric/restricted/binary-amd64/Packages 404 Not Found [IP: 141.30.13.20 80] E: Some index files failed to download.

Also it looks pretty much like, say, the us mirror. But oddly enough, the IP it lists, seems to point to a debian package server, which obviously does not contain ubuntu packages. So, is this a local problem that I can fix somehow (and if so, how?) or is there actually some server down right now?

  Introducing Extensibility Exchange Version 2 On the heals of Enterprise Manager 12c Release 4 this week comes version 2.0 of the Extensibility Exchange.  A new theme allows optimal viewing on a number of different computing devices from large monitor displays to tablets to smartphones.   One of the first things you'll notice is a scrollable banner with the latest news related to Enterprise Manager and extensibility.  Along with the "slider" and the latest entries from Oracle and the Partner community, new features like a tag cloud and an auto-complete search box provide a better way to find the plug-in, connector or other Enterprise Manager entity you are looking for.  Once you find it, a content details page with specific info related to that particular entity will enable you to access it at the provider's site and also rate and comment on that particular item. You can also send an email from the content details page which is routed to the developer.   And if you want to use version 1 of the Extensibility Exchange instead, you will be able to do so via the "Classic" option.  Check it out today at http://www.oracle.com/goto/emextensibility. Recent Additions from Oracle's Partner Community A number of important 3rd party plug-ins have been contributed by Oracle's partner community, which can be accessed via the Extensibility Exchange or by clicking the links in this blog: Dell Open Manage Fusion I-O ION Accelerator NetApp SANtricity E-Series PostgreSQL by Blue Medora You can also check out the following best practices and labs available via the Exchange: Riverbed Stingray Traffic Manager Reference Architecture Datavail Alert Optimizer Custom Templates Apps Associates' Oracle Enterprise Manager "Test Drives" for Oracle Database 12c Management Oracle Enterprise Manager Monitoring Essentials Oracle Application Management Suite for Oracle E-Business Suite

• GitHub: Are there external tools for managing issues list vs. project backlog

  - by DXM

  Recently I posted one of my the projects1 on GitHub and as I was exploring capabilities of the site, I noticed they have a rather decent issue tracking section. I want to use that section as a) other people can report bugs if they'd like and b) other people can see which bugs I'm aware of. However, as others have noted, issues list cannot be prioritized in order to create a project backlog. For now my backlog has been a text file, but I'd like to be able to have it integrated so the same information isn't maintained in different places. Having a fully ordered list, which is something we also practice at work, has been very useful as I can open one file, start with line 1 and fire off 2 or 3 items in one sitting without having to go back to a full issues/stories bucket. GitHub doesn't offer this. What GitHub does offer is a very nice and clean API so issues can easily be exported into anything else. I've searched to see if there are other websites (like Trello) that integrate with GitHub issues, but did not find anything. Does anyone know of such a product, service or offline tool? Those that use GitHub, what is your experience in managing backlog? I kinda hate the idea of manually managing two disconnected lists like some people seem to be doing with Wiki project pages. 1 - are shameless plugs allowed no this site? Searched but didn't find a definite answer. If it's bad practice, STOP and don't read further As a developer I got sick and tired of navigating to same set of folders 30 times a day, so I wrote a little, auto-collapsible utility that gets stuck to the desktop and allows easy access to the folders you constantly use.

• 2D Collision masks for handling slopes

  - by JiminyCricket

  I've been looking at the example at: http://create.msdn.com/en-US/education/catalog/tutorial/collision_2d_perpixel and am trying to figure out how to adjust the sprite once a collision has been detected. As David suggested at XNA 4.0 2D sidescroller variable terrain heightmap for walking/collision, I made a few sensor points (feet, sides, bottom center, etc.) and can easily detect when these points actually collide with non-transparent portions of a second texture (simple slope). I'm having trouble with the algorithm of how I would actually adjust the sprite position based on a collision. Say I detect a collision with the slope at the sprite's right foot. How can I scan the slope texture data to find the Y position to place the sprite's foot so it is no longer inside the slope? The way it is stored as a 1D array in the example is a bit confusing, should I try to store the data as a 2D array instead? For test purposes, I'm thinking of just using the slope texture alpha itself as a primitive and easy collision mask (no grass bits or anything besides a simple non-linear slope). Then, as in the example, I find the coordinates of any collisions between the slope texture and the sprite's sensors and mark these special sensor collisions as having occurred. Finally, in the case of moving up a slope, I would scan for the first transparent pixel above (in the texture's Ys at that X) the right foot collision point and set that as the new height of the sprite. I'm a little unclear also on when I should make these adjustments. Collisions are checked on every game.update() so would I quickly change the position of the sprite before the next update is called? I also noticed several people mention that it's best to separate collision checks horizontally and vertically, why is that exactly? Open to any suggestions if this is an inefficient or inaccurate way of handling this. I wish MSDN had provided an example of something like this, I didn't know it would be so much more complex than NES Mario style pure box platforming!

• Search SSIS packages for table/column references

  - by Nigel Rivett

  A lot of companies now use TFS or some other system and keep all their packages in a single project. This means that a copy of all the packages will end up on your local disk. There is major failing with SSIS that it is sometimes quite difficult to find what a package is actually doing, what it accesses and what it affects. This is a simple dos script which will search through all packages in a folder for a string and write the names of found packages to an output file. Just copy the text to a .bat file (I use aaSearch.bat) in the folder with all the package scripts Change the output filename (twice), change the find string value and run it in a dos window. It works on any text file type so you can also search store procedure scripts – but there are easier ways of doing that. echo. > aaSearch_factSales.txt for /f “delims=” %%a in (‘dir /B /s *.dtsx’) do call :subr “%%a” goto:EOF :subr findstr “factSales” %1 if %ERRORLEVEL% NEQ 1 echo %1 >> aaSearch_factSales.txt goto:EOF
