• Reading mp3 metadata?

  - by Blaze

  I am planing on writing an application using Vala. Its purposed is to import mp3 files from a location and rename them if necessary. The renaming information should be provided by the ID3 tags in the mp3 file such as the title and the number of the song. My target platform is Ubuntu (Linux). As the question says, I am searching for how can I achieve this on Vala. I think this functionality might be provided by Gstreamer.

• Presenting the Cloud in a Different Way

  - by BuckWoody

  I had the honor of presenting the Developers at the Portland PASS chapter, and decided to go a different way than just using PowerPoint Slides…. (click on any picture to enlarge) The point is that when you need to get a point across, it’s OK to change tactics to make sure the information sticks. In this case, I decided to make the audience the PowerPoint. I used a few props to show the various paradigms we use to describe what the industry uses for the word “cloud” First, we talked about Infrastructure as a Service. I picked a gentleman who didn’t quite fit the hard hat and safety vest I picked out for him. Notice our “user” as she accesses our “Server” (complete with tray and glass) which has been virtualized.    Software as a service comes next. In this case, the user and potentially even customers just access software (represented here as a Windows ME box…) remotely – everything is virtualized. Finally, Platform as a Service – Yup, Platform shoes as a necklace, and a tie-dye shirt to represent the 70’s – a decade when mainframes used stateless programming as well. Notice also the components of Windows Azure – Compute (Keyboard) Application Fabric (Toy Bus) and Storage (Bucket).   And at the end of the day, it’s all about serving those customers…

• C Programming matrix

  - by Bilal Khan

  In this program the user enters the # of columns of the matrix and then the entries of the matrix. So, for example, if the user enters 2 for column # and 1 2 3 4 for entries then the program develops a 2 by 2 matrix with 1 2 3 4 as entries. My program works perfectly in such a case. However, if the user for example had only entered 1 2 3 then my program makes a matrix with garbage values. I would like the program in such a case to exit the program. It is a simple question, but it has me baffled. #include<stdio.h> #include<stdlib.h> int main() { int m,x, n, c = 0, d,k, matrix[10][10], transpose[10][10], product[10][10]; printf("Enter the number of columns of matrix "); scanf("%d",&m); if(m<=0){ printf("You entered a invalid value."); exit(0); } else{ printf("Enter the elements of matrix \n"); for( c = 0 ; c < 10 ; c++ ) { for( d = 0 ; d < m ; d++ ) { scanf("%d",&matrix[c][d]); if (matrix[c][d] == 99) // 'x' is character variable I declared to use as a break break; // c = c+1; } if (matrix[c][d] == 99) break; } } printf("\nHere is your matrix:\n"); int i; for(i=0;i<c;i++) { for(d=0;d<m;d++) { printf("%3d ",matrix[i][d]); } printf("\n"); }

• Cross-Platform Migration using Heterogeneous Data Guard

  - by Roy F. Swonger

  Most people think of Data Guard as a disaster recovery solution, and it certainly excels in that role. However, did you know that you can also use Data Guard for platform migration under some conditions? While you would normally have your primary and standby Data Guard systems running on the same OS and hardware platform, there are some heterogeneous combinations of primary and stanby system that are supported by Data Guard Physical Standby. One example of heterogenous Data Guard support is the ability to go between Linux and Windows on many processor architectures. Another is the support for environments that are running HP-UX on both PA-RIsC and Itanium hardware. Brand new in 11.2.0.2 is the ability to have both SPARC Solaris and IBM AIX on Power Systems in the same Data Guard environment. See My Oracle Support note 413484.1 for all the details about supported platform combinations. So, why mention this in an upgrade blog? Simple: much of the time required for a platform migration is usually spent copying files from one system to another. If you are moving between systems that are supported by heterogenous Data Guard, then you can reduce that migration downtime to a matter of minutes. This can be a big win when downtime is at a premium (and isn't downtime always at a premium? In addition, you get the benefit of being able to keep the old and new environments synchronized until you are sure the migration is successful! A great case study of using Data Guard for a technology refresh is located on this OTN page. The case study showing CERN's methodology isn't highlighted as a link on the overview page, but it is clickable. As always, make sure you are fully versed on the details and restrictions by reading the available documentation and MOS notes. Happy migrating!

• Fixed-Function vs Shaders: Which for beginner?

  - by Rob Hays

  I'm currently going to college for computer science. Although I do plan on utilizing an existing engine at some point to create a small game, my aim right now is towards learning the fundamentals: namely, 3D programming. I've already done some research regarding the choice between DirectX and OpenGL, and the general sentiment that came out of that was that whether you choose OpenGL or DirectX as your training-wheels platform, a lot of the knowledge is transferrable to the other platform. Therefore, since OpenGL is supported by more systems (probably a silly reason to choose what to learn), I decided that I'm going to learn OpenGL first. After I made this decision to learn OpenGL, I did some more research and found out about a dichotomy that I was somewhere unaware of all this time: fixed-function OpenGL vs. modern programmable shader-based OpenGL. At first, I thought it was an obvious choice that I should choose to learn shader-based OpenGL since that's what's most commonly used in the industry today. However, I then stumbled upon the very popular Learning Modern 3D Graphics Programming by Jason L. McKesson, located here: http://www.arcsynthesis.org/gltut/ I read through the introductory bits, and in the "About This Book" section, the author states: "First, much of what is learned with this approach must be inevitably abandoned when the user encounters a graphics problem that must be solved with programmability. Programmability wipes out almost all of the fixed function pipeline, so the knowledge does not easily transfer." yet at the same time also makes the case that fixed-functionality provides an easier, more immediate learning curve for beginners by stating: "It is generally considered easiest to teach neophyte graphics programmers using the fixed function pipeline." Naturally, you can see why I might be conflicted about which paradigm to learn: Do I spend a lot of time learning (and then later unlearning) the ways of fixed-functionality, or do I choose to start out with shaders? My primary concern is that modern programmable shaders somehow require the programmer to already understand the fixed-function pipeline, but I doubt that's the case. TL;DR == As an aspiring game graphics programmer, is it in my best interest to learn 3D programming through fixed-functionality or modern shader-based programming?

• How to execute a shell script on startup?

  - by vijay.shad

  I have create a script to start a server(my first question). Now I want it to run on the system boot and start the defined server. What should I do to get this done? My findings tell me put this file in /etc/init.d location and it will execute when the system will boot. But I am not able to understand how the first argument on the startup will be start? Is this predefined somewhere to use start as $1? If I want to have a case startall that will start all the servers in the script, then what are the options I can manage. My Script is like this: #!/bin/bash case "$1" in start) start ;; stop) stop ;; restart) $0 stop $0 start ;; *) echo "usage: $0 (start|stop|restart)" ;; esac

• Computer randomly shuts down with a fading alarm power button and CD drive

  - by Shad

  I am currently experiencing something very very odd. Having build my PC myself, I have never had any issues (or anything heat related). A few moments ago my computer shut down very randomly and everything goes blank, when I looked down on my case's power button it was fading on and off in such way I've had never seen before. I noticed the CD drive all of a sudden also started blinking randomly. What do you guys think this problem is related to? It is definitely not a overheating issue and I am pretty sure my 600 watt power supply didn't blow because right now I am able to turn it on and boot up the PC but 20 seconds later it shuts down (sometimes doesn't shut down for 2 minutes). I have no idea what this is... My specs are (built by myself): i5 3570k (unoverclocked) GTX 560ti Asrock Z77 Pro4-M motherboard 8GB Vengeance RAM 600W Corsair power supply 500GB of Seagate HD Case: Corsair Carbide 300R

• Access functions from user control without events?

  - by BornToCode

  I have an application made with usercontrols and a function on main form that removes the previous user controls and shows the desired usercontrol centered and tweaked: public void DisplayControl(UserControl uControl) I find it much easier to make this function static or access this function by reference from the user control, like this: MainForm mainform_functions = (MainForm)Parent; mainform_functions.DisplayControl(uc_a); You probably think it's a sin to access a function in mainform, from the usercontrol, however, raising an event seems much more complex in such case - I'll give a simple example - let's say I raise an event from usercontrol_A to show usercontrol_B on mainform, so I write this: uc_a.show_uc_b+= (s,e) => { usercontrol_B uc_b = new usercontrol_B(); DisplayControl(uc_b); }; Now what if I want usercontrol_B to also have an event to show usercontrol_C? now it would look like this: uc_a.show_uc_b+= (s,e) => { usercontrol_B uc_b = new usercontrol_B(); DisplayControl(uc_b); uc_b.show_uc_c += (s2,e2) => {usercontrol_C uc_c = new usercontrol_C(); DisplayControl(uc_c);} }; THIS LOOKS AWFUL! The code is much simpler and readable when you actually access the function from the usercontrol itself, therefore I came to the conclusion that in such case it's not so terrible if I break the rules and not use events for such general function, I also think that a readable usercontrol that you need to make small adjustments for another app is preferable than a 100% 'generic' one which makes my code look like a pile of mud. What is your opinion? Am I mistaken?

• Better solution then simple factory method when concrete implementations have different attributes

  - by danip

  abstract class Animal { function eat() {..} function sleep() {..} function isSmart() } class Dog extends Animal { public $blnCanBark; function isSmart() { return $this->blnCanBark; } } class Cat extends Animal { public $blnCanJumpHigh; function isSmart() { return $this->blnCanJumpHigh; } } .. and so on up to 10-20 animals. Now I created a factory using simple factory method and try to create instances like this: class AnimalFactory { public static function create($strName) { switch($strName) { case 'Dog': return new Dog(); case 'Cat': return new Cat(); default: break; } } } The problem is I can't set the specific attributes like blnCanBark, blnCanJumpHigh in an efficient way. I can send all of them as extra params to create but this will not scale to more then a few classes. Also I can't break the inheritance because a lot of the basic functionality is the same. Is there a better pattern to solve this?

• how to configure Firefox to automatically reuse the login credentials like IE

  - by Black Eagle

  Multiple HTTP Authentication Prompts in Firefox We are currently working on porting our application from Internet Explorer to Firefox and the application currently uses HTTP Digest Authentication. In case of Internet Explorer, the popup dialog to enter the Username/password appears only once and the entered login credentials are reused for subsequent HTTP requests to the web server. However in case of Firefox, the Authentication popups appears whenever the request is made to the Web Server. The Web Server used is Emweb Server. We would like to know how to configure Firefox to automatically reuse the login credentials like IE.

• Software development project inception phase

  - by john ryan

  Currently our team develops Web Applications and now we are going to Windows Forms applications. I have created the inception phase for our Windows Forms project structure. eg: ApplicationSolution --> Security Project(Login Authentication) a. Users will be registered with different applications in our application database. eg: ProjectApplicationId|ProjectName | UserId 1 |ProjectApplication1| user 2 |ProjectApplication2| user b. Execute Application (Start) c. On Security dialog, application automatically get the userid of the user and see all the application it is registered using System.Security.Principal.WindowsIdentity.GetCurrent() eg: Prototype Welcome User! Please Choose Appliations you are registered on below: ProjectApplication1 <--this will be a dropdown ProjectApplication2 Password: [*********************] [Access Application Button] d. User selects the application with its password e. If the password is incorrect (application.exit()) else execute Selected Application eg: ProjectApplication1 is selected then execute ProjectApplication1 --> ProjectApplication1 --> ProjectApplication2 --> Many to come ++ if ProjectApplications has been closed then restart security Application. My questions on this use case: Is my use case possible? Can you give me any recommendations ? Currently we use setup and deployment to create installer in each Windows Forms application.

• How can I resolve collisions at different speeds, depending on the direction?

  - by Raven Dreamer

  I have, for all intents and purposes, a Triangle class that objects in my scene can collide with (In actuality, the right side of a parallelogram). My collision detection and resolution code works fine for the purposes of preventing a gameobject from entering into the space of the Triangle, instead directing the movement along the edge. The trouble is, the maximum speed along the x and y axis is not equivalent in my game, and moving along the Y axis (up or down) should take twice as long as an equivalent distance along the X axis (left or right). Unfortunately, these speeds apply to the collision resolution too, and movement along the blue path above progresses twice as fast. What can I do in my collision resolution to make sure that the speedlimit for Y axis movement is obeyed in the latter case? Collision Resolution for this case below (vecInput and velocity are the position and velocity vectors of the game object): // y = mx+c // solve for y. M = 2, x = input's x coord, c = rightYIntercept lowY = 2*vecInput.x + parag.rightYIntercept ; ... else { // y = mx+c // vecInput.y = 2(x) + RightYIntercept // (vecInput.y - RightYIntercept) / 2 = x; //if velocity.Y (positive) greater than velocity.X (negative) //pushing from bottom, so push right. if(velocity.y > -1*velocity.x) { //change the input vector's x position to match the //y position on the shape's edge. Formula for line: Y = MX+C // M is 2, C is rightYIntercept, y is the input y, solve for X. vecInput = new Vector2((vecInput.y - parag.rightYIntercept)/2, vecInput.y); Debug.Log("adjusted rightwards"); } else { vecInput = new Vector2( vecInput.x, lowY); Debug.Log("adjusted downwards"); } }

• Does a Samsung G3 Station external hard drive stop working when power supply is too high?

  - by Cacovsky

  I have a Samsung G3 Station 2TB external hard drive (link to PDF specs here). It was working perfectly when I accidentally plugged it in my notebook's power source. The notebook's power source is 19V/3.42A. The hard drive's is 12V/2A and I know that, inside its case, there is regular 2TB SATA drive, along with some sort of adapter. Does this adapter has some kind of power protection? I opened the case and the hard drive board smells bad. Does my data is forever lost or can I replace its board?

• AWS ELB as backend for Varnish Accelerator

  - by addisonj

  I am working on a large deployment on AWS that has high uptime requirements and variable loads throughout the day. Obviously, this is the perfect use case for ELB (Elastic Load Balancer) and autoscaling. However, we also rely on varnish for caching of API calls. My initial instinct was to structure the stack so that varnish uses ELB as a backend which in turn hits an appGroup. Varnish -> ELB -> AppServers However, according to a few sources that isn't possible as ELB constantly changes the IP address of its DNS hostname, which varnish caches on start, meaning changes to the IP won't be picked up by varnish. Reading around however, it looks like people are doing this so I am wondering what workarounds exist? Perhaps a script to reload the vcl periodically? In the case of where this is really just not a good idea, any idea of other solutions?

• Multiple monitors showing same screen but different resolutions

  - by Luis Alvarado

  Is it possible to have 2 or more monitors showing the same screen, for example the same desktop but with different resolutions. Like the clone option in Nvidia or the mirror option using the Display settings in Ubuntu but instead of showing the same output with the same resolution, the both show the same output using a resolution that is native for each monitor connected. In my case if I have a netbook that has max resolution of 1360x768 and a TV that has 1280x1024, the would both show the same desktop but each with their own resolution that is compatible for each device. This would help in trying to find a resolution that works on both monitors and in cases like a mini netbook and a huge TV it would solve issues like having max 800x600 in one monitor and min 1024x768 in the other. In the case I tested I was using an HDMI cable but this question also involves VGA and any other connection. I have 3 tests scenarios for this: Scenario 1 - Laptop HP DV6000 (Intel Integrated Video) with 1360x760 connected to a Samsung LED 42 TV that has 1280x900. Scenario 2 - Laptop EEE with 1024x600 (Intel Integrated Video) connected to Sony LCD TV that supports 1280x900. Scenario 3 - Intel Desktop with Nvidia 440 GT with HDMI connected to Soneview 32' TV that supports 1920x1080 and VGA connected to an Epson Video Beam that supports 1280x1024 max. In this 3 scenarios I need to be able to show the same desktop and same views but on different resolutions for each output device. UPDATE: Tested with Xubuntu and the way it handles multiple monitors is precisely what I am asking. The ability to handle the resolution of different monitors showing the same thing.

• How to discharge static electricity before opening a computer?

  - by Pekka

  Before opening a computer, I often hear advice to touch something that is "grounded" - a computer case for example, or a heating element - to avoid damaging the sensitive electronic equipment through static discharge. What exactly is true here, and what are the do's and don'ts. Touching what objects will actually work, and what won't? If I touch a computer case, does it matter what it stands on, and whether it is connected to an outlet? What other ways are there to protect the equipment from a static discharge than touching something grounded? Are there common pieces of clothing that I shouldn't be wearing when working inside a computer, for example a woollen pullover? There is a lot on Google, but there seem to be many contradictions and misconceptions out there, so I think this is a question worth having here.

• Recommended total system backup solution

  - by bioShark

  I hope this question won't get closed immediately since it has a generic title. I already searched a bit around the answers here, but nothing satisfied me. I want a back-up solution that makes a total back-up, so that I can restore my Ubuntu in case of major failures, like HDD failing. As far as I can see, I have 2 choices: 1) Backing up with Deja Dup to an external disk. This is fine and I am already doing, but in case my HDD fails, and I make a new Ubuntu install on a new disk, will Deja Dup be able to restore all my setting and stuff from the backed up files? If it can, then what other files/folders should I add in Deja Dup to back-up (currently I have set only the recommended /home folder)? Is there a point in telling Deja Dup to back-up everything under "/" ? 2) A disk/partition cloning software. This would be something similar to Noton ghost. Is there such a software with nice GUI that you could recommend for Ubuntu? And even better, it would be nice if Ubuntu's liveCD could recognize such a clone at install step. I am using 11.10

• Accessing the JSESSIONID from JSF

  - by Frank Nimphius

  The following code attempts to access and print the user session ID from ADF Faces, using the session cookie that is automatically set by the server and the Http Session object itself. FacesContext fctx = FacesContext.getCurrentInstance(); ExternalContext ectx = fctx.getExternalContext(); HttpSession session = (HttpSession) ectx.getSession(false); String sessionId = session.getId(); System.out.println("Session Id = "+ sessionId); Cookie[] cookies = ((HttpServletRequest)ectx.getRequest()).getCookies(); //reset session string sessionId = null; if (cookies != null) { for (Cookie brezel : cookies) {     if (brezel.getName().equalsIgnoreCase("JSESSIONID")) {        sessionId = brezel.getValue();        break;      }   } } System.out.println("JSESSIONID cookie = "+sessionId); Though apparently both approaches to the same thing, they are different in the value they return and the condition under which they work. The getId method, for example returns a session value as shown below grLFTNzJhhnQTqVwxHMGl0WDZPGhZFl2m0JS5SyYVmZqvrfghFxy!-1834097692!1322120041091 Reading the cookie, returns a value like this grLFTNzJhhnQTqVwxHMGl0WDZPGhZFl2m0JS5SyYVmZqvrfghFxy!-1834097692 Though both seem to be identical, the difference is within "!1322120041091" added to the id when reading it directly from the Http Session object. Dependent on the use case the session Id is looked up for, the difference may not be important. Another difference however, is of importance. The cookie reading only works if the session Id is added as a cookie to the request, which is configurable for applications in the weblogic-application.xml file. If cookies are disabled, then the server adds the session ID to the request URL (actually it appends it to the end of the URI, so right after the view Id reference). In this case however no cookie is set so that the lookup returns empty. In both cases however, the getId variant works.

• Benchmarking ORM associations

  - by barerd

  I am trying to benchmark two cases of self referential many to many as described in datamapper associations. Both cases consist of an Item clss, which may require many other items. In both cases, I required the ruby benchmark library and source file, created two items and benchmarked require/unrequie functions as below: Benchmark.bmbm do |x| x.report("require:") { item_1.require_item item_2, 10 } x.report("unrequire:") { item_1.unrequire_item item_2 } end To be clear, both functions are datamapper add/modify functions like: componentMaps.create :component_id => item.id, :quantity => quantity componentMaps.all(:component_id => item.id).destroy! and links_to_components.create :component_id => item.id, :quantity => quantity links_to_components.all(:component_id => item.id).destroy! The results are variable and in the range of 0.018001 to 0.022001 for require function in both cases, and 0.006 to 0.01 for unrequire function in both cases. This made me suspicious about the correctness of my test method. Edit I went ahead and compared a "get by primary key case" to a "finding first matching record case" by: (1..10000).each do |i| Item.create :name => "item_#{i}" end Benchmark.bmbm do |x| x.report("Get") { item = Item.get 9712 } x.report("First") { item = Item.first :name => "item_9712" } end where the results were very different like 0 sec compared to 0.0312, as expected. This suggests that the benchmarking works. I wonder whether I benchmarked the two types of associations correctly, and whether a difference between 0.018 and 0.022 sec significant?

• Acceptable placement of the composition root using dependency injection and inversion of control containers

  - by Lumirris

  I've read in several sources including Mark Seemann's 'Ploeh' blog about how the appropriate placement of the composition root of an IoC container is as close as possible to the entry point of an application. In the .NET world, these applications seem to be commonly thought of as Web projects, WPF projects, console applications, things with a typical UI (read: not library projects). Is it really going against this sage advice to place the composition root at the entry point of a library project, when it represents the logical entry point of a group of library projects, and the client of a project group such as this is someone else's work, whose author can't or won't add the composition root to their project (a UI project or yet another library project, even)? I'm familiar with Ninject as an IoC container implementation, but I imagine many others work the same way in that they can scan for a module containing all the necessary binding configurations. This means I could put a binding module in its own library project to compile with my main library project's output, and if the client wanted to change the configuration (an unlikely scenario in my case), they could drop in a replacement dll to replace the library with the binding module. This seems to avoid the most common clients having to deal with dependency injection and composition roots at all, and would make for the cleanest API for the library project group. Yet this seems to fly in the face of conventional wisdom on the issue. Is it just that most of the advice out there makes the assumption that the developer has some coordination with the development of the UI project(s) as well, rather than my case, in which I'm just developing libraries for others to use?

• Using ASP.NET Membership Provider with an ACL

  - by geekrutherford

  Up until recently one of my applications has used the membership provider within ASP.NET exclusively. However, it has been proposed that while the currently defined roles are beneficial, security needs to be more granular to restrict both access to certain pages and functionality present within a given page.   Unfortunately, the role based security ASP.NET gives you out of the box falls down in this area. This is not due to a lack of foresight by Microsoft, but rather it was simply not designed for implementing both role based security and any inherent ACL you may define within these roles. Mind you some would say an ACL is independent of the role to which a user belongs and is assigned to the user directly.   The application mentioned here has it's own User object (which encapsulates the membership provider user object as a property) and SQL Server table to store extended information not present in the aspnet_users table. While I could have modified the aspnet membership schema to suit the applications needs, it seemed smarter to simply create a separate table with a foreign key back to the aspnet_users table.   Since I have a separate object to store extended user information, I simply created an ACL object and expose it as a property of my user object.   This is all well and good, but it does not help in regards to the SiteMapProvider and restricting access at the page level based on the users ACL.   The straightforward answer would be to develop some code within the databound event for the menu that checks the page title and has hardcoded logic that dictates a user must have certain permissions turned on. The problem with this approach is that it's HARDCODED!!! If you need to change access to a page you'd need to do a build and go through your normal deployment process....ugh!!!   An alternative method, albeit not perfect, is to utilize the resourceKey property on the SiteMapNodes in the SiteMap file with the name of the required permission to view the page. Within the databound event for your menu you iterate the SiteMapNodes in the menus SiteMapProvider looking for a match at the page level based on title. When a match is detected, you have a switch/case on the SiteMapNodes resourceKey (the name of the ACL permission required). The case for the resourceKey ensures the users ACL permission is turned on and viola!!!   This is noteably not perfect in that it is using the resourceKey in a manner other than intended.  Since the application is not localized, using it in the manner described it not an issue.   Below is a sample SiteMap file with the resourceKey used as the ACL permission identifier:     Below is the ItemDataBound event. This application uses the Telerik Menu control:
