• Extension GLX missing...on a desktop PC

  - by Bart van Heukelom

  I just installed Ubuntu 12.10 on a new PC with an Nvidia GTX 560 graphics card, but after installing the Nvidia proprietary drivers (either -current or -current-updates), Unity won't start. When trying to start it manually I get the message "extension GLX missing". I've searched around and found results like this question which point out it's a problem with Nvidia Optimus laptops. However, I don't have this problem on a laptop, but on a desktop PC. lshw output for the graphics card: *-display description: VGA compatible controller product: GF114 [GeForce GTX 560 SE] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:f4000000-f5ffffff memory:e0000000-e7ffffff memory:e8000000-ebffffff ioport:e000(size=128) memory:f6000000-f607ffff and CPU: *-cpu description: CPU product: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz vendor: Intel Corp. physical id: 40 bus info: cpu@0 version: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz slot: SOCKET 0 size: 1600MHz capacity: 3800MHz width: 64 bits clock: 100MHz capabilities: x86-64 fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase smep erms cpufreq configuration: cores=4 enabledcores=4 threads=4

• Don't miss Virtual Developer Day - All about ADF next week

  - by Shay Shmeltzer

  In case you haven't heard we are holding a free online virtual developer day next week - July 10th that you should attend - even if you think you already know ADF. First the registration link - http://bit.ly/fusiondev. While one of the tracks is aimed at developer who are relatively new to ADF - and cover ADF Faces, ADF Controller and a comparison of productivity with Forms and other tools - the two other tracks have great content on some topics that you might not be familiar with even if you already work with ADF. This include sessions about the upcoming ADF Mobile, The new ADF support in Eclipse and information about Application Life Cycle Management with ADF and JDeveloper. As well as sessions that will open your mind to the areas where ADF integrates with other Fusion Middleware Solutions such as ADF integration with BI, WebCenter and SOA. Most of the sessions are quite heavy on demos and you'll get a chance to interact with the presenters and ask questions during the live event. You should register even if you can't attend the live event - this way you'll get an email pointing you to the recorded sessions for on demand viewing. See you next week.

• Back button after doing posts on the same page

  - by user441521

  I have 3 pages to my site. The 1st page allows you to select a bunch of options. Those options get sent to the 2nd page to be displayed with some data about those options. From here I can click on a link to get to page 3 on 1 of the options. On page 3 I can create a new/edit/delete all on the same page where reloads come back to page 3. I want a "back" button on page 3 to go back to page 2, but retain the options it had from the original page 1 request. Page 1 has a bunch of check boxes which are passed to page 2 as arrays to the controller. My thought is that I have to pass these arrays (I converted them to lists) to page 3 (even thought page 3 directly doesn't need them) so that page 3 can use them in the back link to it can recreate the values page 1 sent to page 2 originally. I'm using asp.net MVC and when I pass the converted array it seems to convert it to the type instead of actually showing the values: "types=System.Collections.Generic.List" (where types is a List. Is this what is needed or are there other options to getting a "back" button in this case to go back to page 2. It's sort of a pain to pass information to page 3 that isn't really relevant to page 3 except the back button.

• Database Driven Web Application, C# Front-End and F# Back-End meaning

  - by user1473053

  Hi I am an intern working with ASP.NET. My current task is to make a website which will incorporate some jquery viewing features. This project seems to me will be primarily dealing with reading data from a database and making graphs out of them. This will require me to make custom queries from whatever the client is looking at. I think it is going to be what this guy calls an Ad Hoc Query tool My plan for this is to make it a database-driven website. So I can utilize the jquery dynamic viewing capabilities. I stumbled upon the functional programming paradigm and found F#. I read that because of it's functional programming paradigm, it makes it a good language to do asynchronous functions. I read about how you can use this with LINQ to SQL and how easy it is to make queries without actually putting the query language in. I understand the concept of the MVC design pattern. But I don't understand what they mean about C# being the front-end and F# being the back-end. Can someone clarify this to me? Also what are your thoughts about doing this project in this way? Any comments and thoughts are greatly appreciated. I feel as if learning F# will be a great learning experience for me. My guess is that the F# back-end is like the part where it controls the calls to the database. F# is possibly the model part of the design pattern. And C# is the controller. So HTML, Javascript and Jquery stuff will be my View design pattern. Clarify please?

• Wireless BMC4311 driver install

  - by user113910

  Exasperated with Ubuntu 12.04 and BCM4311 driver. HP2133 (was SUSE 10) Installed 12.04 in March. It ran well until November with no updates) then updates killed my wireless controller. Trolled forums & other for fix. Tried sudo -apt-get ing & gedit ing. Finally got it working (on full update with STA driver) Hwew!—thought that was it, only to fail again after 3-4 days. Tried all the fixes again but sudo -apt-get ing & gedit ing does not fix. I'm not without experience either: first 'boot-loader' I/P from 20 switch panel, seq to 4096 bit core-store: run to I/P larger processes from paper tape reader. Gone thru acoustic-coupled networks-to-billboards (before 'the net') pre-DOS, DOS, Windows 3.1 & all the others. This is a tough problem. Any advice?

• Javascript MVC in principle

  - by Michael

  Suppose I want to implement MVC in JavaScript. I am not asking about MVC frameworks. I am asking how to build it in principle. Let's consider a search page of an e-commerce site, which works s follows: User chooses a product and its attributes and press a "search" button. Application sends the search request to the server, receives a list of products. Application displays the list in the web page. I think the Model holds a Query and list of Product objects and "publishes" such events as "query updated", "list of products updated", etc. The Model is not aware of DOM and server, or course. View holds the entire DOM tree and "subscribes" to the Model events to update the DOM. Besides, it "publishes" such events as "user chose a product", "user pressed the search button" etc. Controller does not hold any data. It "subscribes" to the View events, calls the server and updates the Model. Does it make sense?

• Ubuntu sound volume is 40% lower than in Windows

  - by ncomx

  I have 2x 2.1 speakers connected to the computer where I have Ubuntu 12.04 installed. On the software side I've set all the volume controls to 100% with the alsamixer program. The speakers have their own volume control, maintaining those at the same level, and switching between Ubuntu and Windows (XP and 7), on windows the output volume is at least 40% higher, even when having the windows volume control at 50% (without touching the speakers volume control) it's still much higher than the sound on Ubuntu. Why can this be happening? Are there some alternative sound drivers (other than the default ones) I could test to see if it makes a difference? some info about the card: root:$ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xfbff4000 irq 55 1 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xfbcfc000 irq 56 root:$ lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) 02:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Cayman/Antilles HDMI Audio [Radeon HD 6900 Series] I think the one i am using is the Intel one, the other seems to be from the vga card which is an ati radeon 6950. Running gstreamer-properties and switching between alsa, oss, ossv4 and pulseaudio doesn't seem to make any difference.

• Best design for a "Command Executer" class

  - by Justin984

  Sorry for the vague title, I couldn't think of a way to condense the question. I am building an application that will run as a background service and intermittently collect data about the system its running on. A second Android controller application will query the system over tcp/ip for statistics about the system. Currently, the background service has a tcp listener class that reads/writes bytes from a socket. When data is received, it raises an event to notify the service. The service takes the bytes, feeds them into a command parser to figure out what is being requested, and then passes the parsed command to a command executer class. When the service receives a "query statistics" command, it should return statistics over the tcp/ip connection. Currently, all of these classes are fully decoupled from each other. But in order for the command executer to return statistics, it will obviously need access to the socket somehow. For reasons I can't completely articulate, it feels wrong for the command executer to have a direct reference to the socket. I'm looking for strategies and/or design patterns I can use to return data over the socket while keeping the classes decoupled, if this is possible. Hopefully this makes sense, please let me know if I can include any info that would make the question easier to understand.

• Law of Demeter confusion [duplicate]

  - by user2158382

  This question already has an answer here: Rails: Law of Demeter Confusion 4 answers I am reading a book called Rails AntiPatterns and they talk about using delegation to to avoid breaking the Law of Demeter. Here is their prime example: They believe that calling something like this in the controller is bad (and I agree) @street = @invoice.customer.address.street Their proposed solution is to do the following: class Customer has_one :address belongs_to :invoice def street address.street end end class Invoice has_one :customer def customer_street customer.street end end @street = @invoice.customer_street They are stating that since you only use one dot, you are not breaking the Law of Demeter here. I think this is incorrect, because you are still going through customer to go through address to get the invoice's street. I primarily got this idea from a blog post I read: http://www.dan-manges.com/blog/37 In the blog post the prime example is class Wallet attr_accessor :cash end class Customer has_one :wallet # attribute delegation def cash @wallet.cash end end class Paperboy def collect_money(customer, due_amount) if customer.cash < due_ammount raise InsufficientFundsError else customer.cash -= due_amount @collected_amount += due_amount end end end The blog post states that although there is only one dot customer.cash instead of customer.wallet.cash, this code still violates the Law of Demeter. Now in the Paperboy collect_money method, we don't have two dots, we just have one in "customer.cash". Has this delegation solved our problem? Not at all. If we look at the behavior, a paperboy is still reaching directly into a customer's wallet to get cash out. Can somebody help me clear the confusion. I have been searching for the past 2 days trying to let this topic sink in, but it is still confusing.

• Ubuntu 12.04 - default Radeon driver does not work at all

  - by mumble

  I've recently upgraded to 12.04 LTS and I have an ATI Radeon HD5670. I've heard that the open source 'Radeon' driver is used by default. However, it wasn't showing anything for me. What I did was I added the 'nomodeset' option to boot up and install fglrx. But it didn't work well for me as it introduced a lot of problems (freezes/glitches). So I removed/purged fglrx and am planning to use the open source drivers instead. So my question is this: Why is my default Radeon driver not working? Is anyone having a similar issue? I've also tried using the ubuntu-x-swat driver by running the ff commands: sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update But the result was the same as the Radeon driver. Nothing shows up on system boot. Any ideas? Thanks in advance! Update Running lspci -nn | grep VGA gives me the following: 02:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Redwood [Radeon HD 5670] [1002:68d8]

• What type of pattern would be used in this case

  - by Admiral Kunkka

  I want to know how to tackle this type of scenario. We are building a person's background, from scratch, and I want to know, conceptually, how to proceed with a secure object pattern in both design and execution... I've been reading on Factory patterns, Model-View-Controller types, Dependency injection, Singleton approaches... and I can't seem to grasp or 'fit' these types of designs decisions into what I'm trying to do.. First and foremost, I started with having a big jack-of-all-trades class, then I read some more, and some tips were to make sure your classes only have a single purpose.. which makes sense and I started breaking down certain things into other classes. Okay, cool. Now I'm looking at dependency injection and kind of didn't really know what's going on. Example/insight of what kind of heirarchy I need to accomplish... class Person needs to access and build from a multitude of different classes. class Culture needs to access a sub-class for culture benefits class Social needs to access class Culture, and other sub-classes class Birth needs to access Social, Culture, and other sub-classes class Childhood/Adolescence/Adulthood need to access everything. Also, depending on different rolls, this class heirarchy needs to create multiple people as well, such as Family, and their backgrounds using some, if not all, of these same classes. Think of it as a people generator, all random, with backgrounds and things that happen to them. Ageing, death of loved ones, military careers, e.t.c. Most of the generation is done randomly, making calls to a mt_rand function to pick from most of the selections inside the classes, guaranteeing the data to be absolutely random. I have most of the bulk-data down, and was looking for some insight from fellow programmers, what do you think?

• Learning curve webdevelopment

  - by refro

  At the moment our team has a huge challenge, we're being asked to deliver a new GUI for an embedded controller. De deadline is very tight and is set on april 2013. Our team is very diverse some people are on the level of functional programming (mostly C), others (including myself) also master object oriented programming (C++, C#). We build a prototype with android, although it has its quirks it is mostly just OO. For the future there is a wish to support multiple platforms (Windows, Android, iOS). In my opinion a HTML5 app with a native app shell is the way to go. When gathering more information on the frameworks to use etc it becomes obvious to me a paradigm shift is needed. None of us have a web background so we need to learn from the ground up. The shift from functional to oo took us about 6 months to become productive (and some of the early subsystems were rewritten because they were a total mess) . Can we expect the learning curve to be similar? Can this be pulled off with a webapp? (My feeling says it will already be hard to pull off as a native app which is at the edge of our comfort zone)

• wireless blocked after installing ubuntu 12.04

  - by Cornelia Frank

  I am using a lenovo S10-3 ideapad; had no problems with earlier version of ubuntu, only since installing 12.04. Have looked through many of the questions on the same issue and tried potential solutions but cannot seem to solve my problem. The hardware switch is in 'on' position and the wireless light comes on very briefly (2-3 sec) when the laptop starts up but then goes off and stays off. Pressing FN+F5 does nothing at all.

• Photo transfer problems from camera

  - by warkior

  We have a digital camera (Cannon SX130 IS) which we often connect to the Ubuntu 12.10 desktop via USB in order to download the images. In past flavours of Linux (Mint 12 was most recent) it worked fine, however since upgrading to Ubuntu 12.10, the process fails after downloading a small number of the images. I can view the images which will be transferred in the preview window, and I can browse the camera file system to download the images manually, but if I just drag/drop the images over from camera to desktop, it freezes after 5-6 are copied over. I've been able to get around the problem by only copying 3-4 at a time, but when you have 100+ images to transfer, that gets really frustrating. Any advice on where I could start looking for answers, or how I could diagnose the source of the problem further? We have also had some issues with WireLess USB mice though it may not be related. I'm hoping my USB controller in the computer isn't dying... it's not that old. Also, it seems to work much better under Windows.

• .htaccess rules to rewrite URLs to front end page?

  - by Dizzley

  I am adding a new application to my site at example.com/app. I want views at that URL to always open myapp.php. E.g. example.com/app -> example.com/app/myapp.php and example.com/app/ -> example.com/app/myapp.php What's the correct form of rewrite rules in the .htaccess file? I've got: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /app/ RewriteRule ^myapp\.php$ - [L] RewriteRule ^myapp.php$ - [L] RewriteRule . - [L] </IfModule> ...based on what the Wordpress front-end does. But all I see at example.com/app is a directory of files. :( (I put those rewrites at the top of my .htaccess file). Any ideas? Update What actually worked: RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} ^/app(/.*)?$ [NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule . /app/myapp.php [L] This is good because: Explicit or implicit calls to app/myapp.php work. example.com/app redirects to app/myapp.php example.com/app/ redirects to app/myapp.php example.com/app/subfunction redirects to app/myapp.php All other calls to example.com/otherstuff are untouched. Item 4 is Wordpress-like Front Controller pattern behaviour. I think that rule RewriteCond %{REQUEST_URI} ^/app.*$ [NC] needs refining as it allows /app-oh-my-goodness etc. through too. Thanks for the answers.

• No space left on disk

  - by Ned

  folks. I'm trying to copy/move files to an external 1 TB hard drive with about 50 GB remaining space. I receive a "no space left on disk" when I try. I've moved files off and retried, but still get the same message. Disk Usage Analyzer, Properties, and freeware Treesize all report available hard drive space of about 50 GB. I've tried df -i (50 GB available) and df -k, with the latter reporting only 1% of inode usage. I've been able to save files from Firefox to the drive also. I can't even rename files without getting the message. Yesterday in the midst of trying to figure this out I tried to move 4 files to the drive and got the message. Today, I found them on the drive. What's up with that? (That's the only time that has happened to my knowledge.) Is this an ubuntu problem? or is my hard drive just about to fail because of something like a controller problem? Any thoughts would be appreciated.

• Audio comes out of both headphone and speaker at the same time.. Ubuntu 12.04LTS [closed]

• correct way to implement auth/acl in mvc

  - by WiseStrawberry

  I am looking into making a correctly laid out MVC auth/acl system. I think I want the authentication of a user (and the session handling) to be seperate from the ACL system. (I don't know why but this seems a good idea from the things I've read) What does mvc have to do with this question you ask? Because I wish for the application to be well integrated with my acl. An example of a controller (CodeIgniter) <?php class forums extends MX_Controller { $allowed = array('users', 'admin'); $need_login = true; function __construct() { //example of checking if logged in. if($this->auth->logged_in() && $this->auth->is_admin()) { echo "you're logged in!"; } } public function add_topic() { if($this->auth->allowed('add_topic') { //some add topic things. } else { echo 'not allowed to add topic'; } } } ?> My thoughts $this->auth would be autoloaded in the system. I would like to check the $allowed array against the user currently (not) logged in and react accordingly. Is this a good way of doing things? I haven't seen much literature on mvc integration and auth. I want to make things as easy as possible.

• Rails: The Law of Demeter [duplicate]

  - by user2158382

  This question already has an answer here: Rails: Law of Demeter Confusion 4 answers I am reading a book called Rails AntiPatterns and they talk about using delegation to to avoid breaking the Law of Demeter. Here is their prime example: They believe that calling something like this in the controller is bad (and I agree) @street = @invoice.customer.address.street Their proposed solution is to do the following: class Customer has_one :address belongs_to :invoice def street address.street end end class Invoice has_one :customer def customer_street customer.street end end @street = @invoice.customer_street They are stating that since you only use one dot, you are not breaking the Law of Demeter here. I think this is incorrect, because you are still going through customer to go through address to get the invoice's street. I primarily got this idea from a blog post I read: http://www.dan-manges.com/blog/37 In the blog post the prime example is class Wallet attr_accessor :cash end class Customer has_one :wallet # attribute delegation def cash @wallet.cash end end class Paperboy def collect_money(customer, due_amount) if customer.cash < due_ammount raise InsufficientFundsError else customer.cash -= due_amount @collected_amount += due_amount end end end The blog post states that although there is only one dot customer.cash instead of customer.wallet.cash, this code still violates the Law of Demeter. Now in the Paperboy collect_money method, we don't have two dots, we just have one in "customer.cash". Has this delegation solved our problem? Not at all. If we look at the behavior, a paperboy is still reaching directly into a customer's wallet to get cash out. EDIT I completely understand and agree that this is still a violation and I need to create a method in Wallet called withdraw that handles the payment for me and that I should call that method inside the Customer class. What I don't get is that according to this process, my first example still violates the Law of Demeter because Invoice is still reaching directly into Customer to get the street. Can somebody help me clear the confusion. I have been searching for the past 2 days trying to let this topic sink in, but it is still confusing.

• 1080p Screen resolution problem after 10.04 to 12.04 update

  - by Ale

  I have a Samsung LCD 40" with a NVidia GeForce 6150SE nForce 430 Card. I recently upgraded from 10.04 to 12.04 and the best resolution I can get is 1360x768. I've tried the propietary drivers available on the repository kmod:nvidia_current kmod:nvidia_173_updates kmod:nvidia_current_updates kmod:nvidia_96 kmod:nvidia_96_updates kmod:nvidia_173 I've also downloaded latest from NVidia's Web, version: 295.40. But still no luck. With Nouveau driver, I can only get 1024x768. I know there is no problem with my hardware (video card, cable and monitor), I was using it perfectly on 10.04. Can anybody suggest something else I could try, to get my 1920x1080 resolution back? Thanks in advance.

• Design Pattern for Skipping Steps in a Wizard

  - by Eric J.

  I'm designing a flexible Wizard system that presents a number of screens to complete a task. Some screens may need to be skipped based on answers to prompts on one or more previous screens. The conditions to skip a given screen need to be editable by a non-technical user via a UI. Multiple conditions need only be combined with and. I have an initial design in mind, but it feels inelegant. I wonder if there's a better way to approach this class of problem. Initial Design UI where The first column allows the user to select a question from a previous screen. The second column allows the user to select an operator applicable to the type of question asked. The third column allows the user to enter one or more values depending on the selected operator. Object Model public enum Operations { ... } public class Condition { int QuestionId { get; set; } Operations Operation { get; set; } List<object> Parameters { get; private set; } } List<Condition> pageSkipConditions; Controller Logic bool allConditionsTrue = pageSkipConditions.Count > 0; foreach (Condition c in pageSkipConditions) { allConditionsTrue &= Evaluate(previousAnswers, c); } // ... private bool Evaluate(List<Answers> previousAnswers, Condition c) { switch (c.Operation) { case Operations.StartsWith: // logic for this operation // etc. } }

• No sound after upgrading to Ubuntu 11.10 from win7

  - by Tilman

  just as a prefix to my question, i'd like to note that i'm just now entering the world of Linux (unless you count my android, but that's a very different experience...) i have two computers now that run Ubuntu 11.10, the first of which i've had very little problems with, aside from figuring out the basics. the second, from which i'm writing this question, has (up to this point) only had one problem.... no sound. i've read a couple questions similiar and found little help as the component catalog doesn't have my computer listed. (in fact i'm not suprised this is a pos i had my mom grab from her work before they officially closed the doors behind them) had perfect sound before hand, and no sound now. sudo lspci -v brings up 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) Subsystem: Intel Corporation Device d608 Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at ff980000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel any help would be greatly appreciated, me and my gf just wanna watch a damn movie lol

• Where should "display functions" live in an MVC web app?

  - by User

  I'm using the Yii Framework which is an MVC php framework that is pretty similar to your standard web-based MVC framework. I want to display the related data from a many-to-many table as a list of strings in my view. Assuming a table schema like: tag { id, name } post { id, title, content, date } post_tag { post_id, tag_id } A post will display like: Date: 9/27/2012 Title: Some Title Content: blah blah blah... Tags: Smart Funny Cool Informative I can achieve this by doing something like this in my Post view: <?php echo join(' ', array_map(function($tag) { return $tag->name; }, $model->tags)); ?> (where $model->tags is an array of Tag objects associated with my model) My questions are: Is this amount of code/logic okay in the view? (Personally I think I'd rather just reference a property or call a single function.) If not, where should this code live? In the model? the controller? a helper? Potentially I may want to use in in other views as well. Ultimately I think its purely a display issue which would make me think it should be in the view, but then I have to repeat the code in any view I want to use it in.
