  • Increase Performance of VS 2010 by using a SSD

    - by System.Data
    After searching on the internet for performance improvements when using Visual Studio 2010 with a solid state hard drive, I heard a lot of different opinions. A lot of people said that there isn't really a benefit when using a SSD, but in contrast others said the exact opposite. I am a bit confused with the contrasting opinions and I cannot really make a decision whether buying a SSD would make a difference. What are your experiences with this issue and which SSD did you use?

  • Can the customer be a SCRUM Product Owner in a project?

    - by Morten
    I just had a discussion with a colleague about the Product Owner role: In a project where a customer organization has brought in a sofware developing organization (supplier), can the role of Product Owner be successfully held by the customer organization, or should it always be held by the supplier? I always imagined, that the PO was the supplier organizations guy. The guy that ensured that the customer is happy, and continously fed with new and high-businessvalue functionality, but still an integral part of the developer organization. However, maybe I have viewed the PO role too much like the waterfall project manager. My colleague made me think: If the customer organization is mature and proffessional enough, why not let a person from their camp prioritize the backlog?? That would put the PO role much closer to the business, thus being (in theory) better to assess the business value of backlog items. To me, that is an intriguing thought. But what are the implication of such a setup??? I look forward to your input.

  • Getting into driver development for linux [closed]

    - by user1103966
    Right now, I've been learning about writing device-drivers for linux 3.2 kernel for about 2 months. So far I have been able program simple char drivers that only read and write to a fictitious dev structure like a file, but now I'm moving to more advance concepts. The new material I've learned about includes I/O port manipulation, memory management, and interrupts. I feel that I have a basic understanding of overall driver operation but, there is still so much that I don't know. My question is this, given that I have the basic theory of how to write a dev-driver for a piece of hardware ... how long would it take to actually develop the skills of writing actual software that companies would want to employ? I plan on getting involved in an open-source project and building a portfolio. Also what type of beginner drivers could I write for hardware that would best help me develop my skills? I was thinking that taking on a project where I design my own key logger would easy and a good assignment to help me understand how IO ports and interrupts are used. I may want to eventually specialize in writing software for video cards or network devices though these devices seem beyond my understanding at the moment. Thanks for any help

  • Creating reproducible builds to verify Free Software

    - by mikkykkat
    Free Software is about freedom and privacy, Open Source software is great but making that fully practical usually won't happen. Most Free Software developers publicize binaries that we can't verify are really compiled from the source code or have something bad injected already! We have the freedom to change the code, but privacy for ordinary users is missing. For desktop software there is a lot of languages and opportunities to create Free Software with a reproducible build process (compiling source code to always produce the exact same binary), but for mobile computing I don't know if same thing is possible or not? Mobile devices are probably the future of computing and Android is the only Open Source environment so far which accept Java for coding. Compiling same Android application won't result in the exact same binary every time. For Open Source Android apps how we can verify the produced binary (.apk) is really compiled from the source code? Is there any way to create reproducible builds from the Android SDK or does Java fail here for Free Software? is there any java software ever wrote with a reproducible build?

  • Do I need to contact a lawyer to report a GPL violation in software distributed on Apple's App Store?

    - by Rinzwind
    Some company is selling software through Apple's App Store which uses portions of code that I released publicly under the GPL. The company is violating the licensing terms in two ways, by (1) not preserving my copyright statement, and not releasing their code under the GPL license and (2) by distributing my GPL-licensed code through Apple's App Store. (The Free Software Foundation has made clear that the terms of the GPL and those of the App Store are incompatible.) I want to report this to Apple, and ask that they take appropriate action. I have tried mailing them to ask for more information about the reporting process, and have received the automated reply quoted below. The last point in the list of things one needs to provide, the “a statement by you, made under penalty of perjury,” sounds as if they mean some kind of specific legal document. I'm not sure. Does this mean I need to contact a lawyer just to file the report? I'd like to avoid going through that hassle if at all possible. (Besides an answer to this specific question, I'd welcome comments and experience reports from anyone who has already had to deal with a GPL violation on Apple's App Store.)

  • Ways of Gathering Event Information From the Internet

    - by Ciwan
    What are the best ways of gathering information on events (any type) from the internet ? Keeping in mind that different websites will present information in different ways. I was thinking 'smart' web crawlers, but that can turn out to be extremely challenging, simply because of the hugely varied ways that different sites present their information. Then I was thinking of sifting through the official twitter feeds of organisations, people with knowledge of events .. etc and look for the event hash tag, grab the tweet and dissect it to grab the relevant information about the event. Information I am interested in gathering is: Date and Time of Event, Address where Event is being held, and any Celebrities (or any famous people) attending the event (if any). The reason to ask here is my hope that experienced folk will open my eyes to things I've missed, which I am sure I have.

  • I'm 15 years old. What would you recommend for resources?

    - by JacKeown
    Hi. I'm a 15 year old kid who seems to excel in all of his classes, likes talking in 3rd person, and wants to learn more about programming and a little about html/php stuff. I already know a little python and I'm hoping to eventually learn Java/Javascript and C. I've been looking around and I've found some online lectures like this and some other tutorials that are so mind numbingly boring and difficult to understand...I was wondering if any of you knew of any good books or other resources that would actually teach me everything I'd need to know incrementally... Thanks in advance!

  • How to check any undocumented methods provided by apple?

    - by Mahbubur R Aaman
    The following tools is provided by Apple dlopen dlsym objc_getClass sel_registerName objc_msgSend Those are listing Objective-C selectors, or strings. Objective-C selectors are stored in a special region of the binary, and therefore Apple could extract the content from there, and check if you've used some undocumented Objective-C methods. How to utilize these tools to find undocumented Objective-C methods? EDIT: Recently, one of my App rejected due to using one undocumented methods. -[UIDevice setOrientation] Since, selectors are independent from the class you're messaging, even if my custom class defines -setOrientation: irrelevant to UIDevice, there will be a possbility of being rejected.

  • Adding page title to each page while creating a PDF file using itextsharp in VB.NET

    - by Snowy
    I have recently started using itextsharp and gradually learning it. So far I created a PDF file and it seems great. I have added a table and some subtables as the first table cells to hold data. It is done using two for loops. The first one loops through all data and the second one is each individual data displayed in columns. The html outcome looks like the following: <table> <tr> <td>Page title in center</td> </tr> <tr> <td> <table> <tr> <td>FirstPersonName</td> <td>Rank1</td> <td>info1a</td> <td>infob</td> <td>infoc</td> </tr> </table> </td> <td> <table> <tr> <td>SecondPersonName</td> <td>Rank2</td> <td>info1a</td> <td>infob</td> <td>infoc</td> <td>infod</td> <td>infoe</td> </tr> </table> </td> <td> <table> <tr> <td>ThirdPersonName</td> <td>Rank2</td> <td>info1a</td> <td>infob</td> <td>infoc</td> <td>infod</td> <td>infoe</td> <td>infof</td> <td>infog</td> </tr> </table> </td> </tr> </table> For page headings, I added a cell at the top before any other cells. I need to add this heading to all pages. Depending on the size of data, some pages have two rows and some pages have three rows of data. So I can not tell exactly when the new page starts to add the heading/title. My question is how to add the heading/title to all pages. I use VB.net. I searched for answer online and had no success. Your help would be greatly appreciated.

  • Is it possible to write a program that pipes the sound from one computer through the sound card of another?

    - by Kenneth
    I have a case where I need to use one computer's sound card to play sound but I want the sound to be generated at another computer that's on the same network as the other. Ideally the program that does this would only run on the computer that was generating the sound, though I'm fairly certain that isn't possible based on the research I have been doing. What ever I do with it though the solution would need to be such that the computer actually playing the sound would be secure. Thanks for any input.

  • How do you prefer to handle image spriting in your web projects?

    - by Macy Abbey
    It seems like these days it is pretty much mandatory for web applications to sprite images if they want many images on their site AND a fast load time. (Spriting is the process of combining all images referenced from a style sheet into one/few image(s) with each reference containing a different background position.) I was wondering what method of implementing sprites you all prefer in your web applications, given that we are referring to non-dynamic images which are included/designed by the programming team and not images which are dynamically uploaded by a third party. 1. Add new images to an existing sprite by hand, create new css reference by hand. 2. Generate a sprite server-side from your css files which all reference single images set to be background images of an html element that is the same size of the image you are spriting once per build and update all css references programmatically. 3. Use a sprite generating program to generate a sprite image for you once per release and hand insert the new css class / image into your project. 4. Other methods? I prefer two as it requires very little hand-coding and image editing.

  • mp3 file streaming/download - apache server memory issue

    - by Manolis
    I have a website, in which users can upload mp3 files (uploadify), stream them using an html5 player (jplayer) and download them using a php script (www.zubrag.com/scripts/). When a user uploads a song, the path to the audio file is saved in the database and i'm using that data in order to play and show a download link for the song. The problem that i'm experiencing is that, according to my host, this method is using a lot of memory on the server, which is dedicated. Link to script: http://pastebin.com/Vus8SRa7 How should I handle the script properly? And what would be the best way to track down the problem? Any ideas on cleaning up the code? Any help much appreciated.

  • Naming methods that do the same thing but return different types

    - by Konstantin Ð.
    Let's assume that I'm extending a graphical file chooser class (JFileChooser). This class has methods which display the file chooser dialog and return a status signature in the form of an int: APPROVE_OPTION if the user selects a file and hits Open /Save, CANCEL_OPTION if the user hits Cancel, and ERROR_OPTION if something goes wrong. These methods are called showDialog(). I find this cumbersome, so I decide to make another method that returns a File object: in the case of APPROVE_OPTION, it returns the file selected by the user; otherwise, it returns null. This is where I run into a problem: would it be okay for me to keep the showDialog() name, even though methods with that name — and a different return type — already exist? To top it off, my method takes an additional parameter: a File which denotes in which directory the file chooser should start. My question to you: Is it okay to call a method the same name as a superclass method if they return different types? Or would that be confusing to API users? (If so, what other name could I use?) Alternatively, should I keep the name and change the return type so it matches that of the other methods? public int showDialog(Component parent, String approveButtonText) // Superclass method public File showDialog(Component parent, File location) // My method

  • Handling permissions in a MVP application

    - by Chathuranga
    In a windows forms payroll application employing MVP pattern (for a small scale client) I'm planing user permission handling as follows (permission based) as basically its implementation should be less complicated and straight forward. NOTE : System could be simultaneously used by few users (maximum 3) and the database is at the server side. This is my UserModel. Each user has a list of permissions given for them. class User { string UserID { get; set; } string Name { get; set; } string NIC {get;set;} string Designation { get; set; } string PassWord { get; set; } List <string> PermissionList = new List<string>(); bool status { get; set; } DateTime EnteredDate { get; set; } } When user login to the system it will keep the current user in memory. For example in BankAccountDetailEntering view I control the controller permission as follows. public partial class BankAccountDetailEntering : Form { bool AccountEditable {get; set;} private void BankAccountDetailEntering_Load(object sender, EventArgs e) { cmdEditAccount.enabled = false; OnLoadForm (sender, e); // Event fires... If (AccountEditable ) { cmdEditAccount.enabled=true; } } } In this purpose my all relevant presenters (like BankAccountDetailPresenter) should aware of UserModel as well in addition to the corresponding business Model it is presenting to the View. class BankAccountDetailPresenter { BankAccountDetailEntering _View; BankAccount _Model; User _UserModel; DataService _DataService; BankAccountDetailPresenter( BankAccountDetailEntering view, BankAccount model, User userModel, DataService dataService ) { _View=view; _Model = model; _UserModel = userModel; _DataService = dataService; WireUpEvents(); } private void WireUpEvents() { _View.OnLoadForm += new EventHandler(_View_OnLoadForm); } private void _View_OnLoadForm(Object sender, EventArgs e) { foreach(string s in _UserModel.PermissionList) { If( s =="CanEditAccount") { _View.AccountEditable =true; return; } } } public Show() { _View.ShowDialog(); } } So I'm handling the user permissions in the presenter iterating through the list. Should this be performed in the Presenter or View? Any other more promising ways to do this? Thanks.

  • Web Developer interview questions

    - by Baba
    I read an article today that listed some basic questions about web development: Describe how POST data was submitted to a server by a browser. Explain a number of HTTP status codes (except maybe 404 and 500). Explain SOLID or name a design pattern. Explain ways to improve a page load speed or user experience. The author says "if you can’t answer the questions above there are a lot of people who wouldn’t think of you as a Senior Web Developer." My questions are: How relevant are these questions in respect to real life web programming and scalability? How true is that statement? In other words, do you consider this knowledge a requirement to be considered a Senior Web Developer? I was able to answer all the questions, too easily it seemed, so I'm wondering whether it is effective to use these or similar questions to screen developers rather than asking them to write sample code.

  • Constructor vs setter validations

    - by Jimmy
    I have the following class : public class Project { private int id; private String name; public Project(int id, String name, Date creationDate, int fps, List<String> frames) { if(name == null ){ throw new NullPointerException("Name can't be null"); } if(id == 0 ){ throw new IllegalArgumentException("id can't be zero"); } this.name = name; this.id = id; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } } I have three questions: Do I use the class setters instead of setting the fields directly. One of the reason that I set it directly, is that in the code the setters are not final and they could be overridden. If the right way is to set it directly and I want to make sure that the name filed is not null always. Should I provide two checks, one in the constructor and one in the setter. I read in effective java that I should use NullPointerException for null parameters. Should I use IllegalArgumentException for other checks, like id in the example.

  • Behavior-Driven Development / Use case diagram

    - by Mik378
    Regarding growing of Behavior-Driven Development imposing acceptance testing, are use cases diagram useful or do they lead to an "over-documentation"? Indeed, acceptance tests representing specifications by example, as use cases promote despite of a more generic manner (since cases, not scenarios), aren't they too similar to treat them both at the time of a newly created project? From this link, one opinion is: Another realization I had is that if you do UseCases and automated AcceptanceTests you are essentially doubling your work. There is duplication between the UseCases and the AcceptanceTests. I think there is a good case to be made that UserStories + AcceptanceTests are more efficient way to work when compared to UseCases + AcceptanceTests. What to think about?

  • Learning Asynchronous programming

    - by xenoterracide
    Asynchronous non-blocking event driven programming seems to be all the rage. I have a basic conceptual understanding of what this all means. However what I'm not sure is when and where my code can benefit from being asynchronous, or how to make blocking IO, non-blocking. I'm sure that I can simply use a library to do this, but I'm more interested in more in depth concepts, and the various ways to implement it myself. Are there any comprehensive/definitive books, or other resources on this subject (like GoF for Design Patterns, or K&R for C, tldp for things like bash)? (Note: I'm not sure if this is actually functionally an identical question to my question on Learning event driven programming)

  • Sharing authentication methods across API and web app

    - by Snixtor
    I'm wanting to share an authentication implementation across a web application, and web API. The web application will be ASP.NET (mostly MVC 4), the API will be mostly ASP.NET WEB API, though I anticipate it will also have a few custom modules or handlers. I want to: Share as much authentication implementation between the app and API as possible. Have the web application behave like forms authentication (attractive log-in page, logout option, redirect to / from login page when a request requires authentication / authorisation). Have API callers use something closer to standard HTTP (401 - Unauthorized, not 302 - Redirect). Provide client and server side logout mechanisms that don't require a change of password (so HTTP basic is out, since clients typically cache their credentials). The way I'm thinking of implementing this is using plain old ASP.NET forms authentication for the web application, and pushing another module into the stack (much like MADAM - Mixed Authentication Disposition ASP.NET Module). This module will look for some HTTP header (implementation specific) which indicates "caller is API". If the header "caller is API" is set, then the service will respond differently than standard ASP.NET forms authentication, it will: 401 instead of 302 on a request lacking authentication. Look for username + pass in a custom "Login" HTTP header, and return a FormsAuthentication ticket in a custom "FormsAuth" header. Look for FormsAuthentication ticket in a custom "FormsAuth" header. My question(s) are: Is there a framework for ASP.NET that already covers this scenario? Are there any glaring holes in this proposed implementation? My primary fear is a security risk that I can't see, but I'm similarly concerned that there may be something about such an implementation that will make it overly restrictive or clumsy to work with.

  • Accessing the same service more than twice in the nick of time

    - by PointedC
    I have an application that will access interface service A which is to run from windows startup. This service is used by program B and my application functions on B's presence after getting a pointer to A. The scenario is translated as follows, public interface A{} ///my program public class MyProgram { public MyProgram() { ProgramB.DoA(); } public A GetA(){} } public class ProgramB { void DoA(){} } The translated source is not true, but that seems to be what I am looking for. In order to eliminate the overhead of allocating and realocating dynamic accesses to the same service used by other processes, would you please provide an actual solution to the problem ?(I am all out of any idea now)

  • Codifying a natural language requirements spec

    - by ProfK
    I have a fairly technical functionality requirements spec, expressed in English prose, produced by my project manager. It is structured as a collection of UI tabs, where the requirements for each tab are expressed as a lit of UI fields and a list of business rules for the tab. Most business rules are for UI fields on a tab, e.g: a) Must be alphanumeric, max length 20. b) Must be a dropdown, with values from table x. c) Is mandatory. d) Is mandatory under certain conditions, e.g. another field is just populated, or has a specific value. Then other business rules get a little more complex. The spec is for a job application, so the central business object (table) is the Applicant, and we have several other tables with one-to-many relationships with applicant, such as Degree, HighSchool, PreviousEmployer, Diploma, etc. e) One such complex rule says a status field can only be assigned a certain value if a many-side record exists in at least one of the many-side tables. E.g. the Applicant has at least one HighSchool or at least one Diploma record. I am looking for advice on how to codify these requirements into a more structured specification defined in terms of tables, fields, and relationships, especially for the conditional rules for fields and for the presence of related records. Any suggestions and advice will be most welcome, but I would be overjoyed if i could find an already defined system or structure for expressing things like this.

  • Improvements to Joshua Bloch's Builder Design Pattern?

    - by Jason Fotinatos
    Back in 2007, I read an article about Joshua Blochs take on the "builder pattern" and how it could be modified to improve the overuse of constructors and setters, especially when an object has a large number of properties, most of which are optional. A brief summary of this design pattern is articled here [http://rwhansen.blogspot.com/2007/07/theres-builder-pattern-that-joshua.html]. I liked the idea, and have been using it since. The problem with it, while it is very clean and nice to use from the client perspective, implementing it can be a pain in the bum! There are so many different places in the object where a single property is reference, and thus creating the object, and adding a new property takes a lot of time. So...I had an idea. First, an example object in Joshua Bloch's style: Josh Bloch Style: public class OptionsJoshBlochStyle { private final String option1; private final int option2; // ...other options here <<<< public String getOption1() { return option1; } public int getOption2() { return option2; } public static class Builder { private String option1; private int option2; // other options here <<<<< public Builder option1(String option1) { this.option1 = option1; return this; } public Builder option2(int option2) { this.option2 = option2; return this; } public OptionsJoshBlochStyle build() { return new OptionsJoshBlochStyle(this); } } private OptionsJoshBlochStyle(Builder builder) { this.option1 = builder.option1; this.option2 = builder.option2; // other options here <<<<<< } public static void main(String[] args) { OptionsJoshBlochStyle optionsVariation1 = new OptionsJoshBlochStyle.Builder().option1("firefox").option2(1).build(); OptionsJoshBlochStyle optionsVariation2 = new OptionsJoshBlochStyle.Builder().option1("chrome").option2(2).build(); } } Now my "improved" version: public class Options { // note that these are not final private String option1; private int option2; // ...other options here public String getOption1() { return option1; } public int getOption2() { return option2; } public static class Builder { private final Options options = new Options(); public Builder option1(String option1) { this.options.option1 = option1; return this; } public Builder option2(int option2) { this.options.option2 = option2; return this; } public Options build() { return options; } } private Options() { } public static void main(String[] args) { Options optionsVariation1 = new Options.Builder().option1("firefox").option2(1).build(); Options optionsVariation2 = new Options.Builder().option1("chrome").option2(2).build(); } } As you can see in my "improved version", there are 2 less places in which we need to add code about any addition properties (or options, in this case)! The only negative that I can see is that the instance variables of the outer class are not able to be final. But, the class is still immutable without this. Is there really any downside to this improvement in maintainability? There has to be a reason which he repeated the properties within the nested class that I'm not seeing?

  • Should a domain expert make class diagrams?

    - by Matthieu
    The domain expert in our team uses UML class diagrams to model the domain model. As a result, the class diagrams are more of technical models rather than domain models (it serves of some sort of technical specifications for developpers because they don't have to do any conception, they just have to implement the model). In the end, the domain expert ends up doing the job of the architect/technical expert right? Is it normal for a domain expert (not a developer or technical profile) to do class diagrams? If not, what kind of modeling should he be using?

  • Is it more difficult to upgrade your certification from SQL Server 2008 to 2012 than to get it from scratch?

    - by Diego
    I was wondering about the new MCSA certification on SQL 2012 and how it seems to be more difficult to upgrade your certification from 2008 to 2012 than to get the 2012 from scratch. Reason I think that is true is because anyone with any MCTS SQL Server 2008 certification can upgrade it to a MCSA 2012 by passing 2 tests (457 and 458). If you try to get it from scratch, you need to pass 3 tests (461, 462 and 463 - which are pretty much the same as 432, 433 and 448 for SQL 2008). But the thing is, even though its one test less to upgrade, all the skills necessary to pass 461, 462 and 463 are squeezed on 457 and 458 so, it seems easier to get from scratch than upgrade. Any thoughts?
