  • What kind of screen has the best image quality for reading/programming?

    - by EpsilonVector
    I'm thinking about buying a new laptop, and while I bought my original one oblivious to the fact that there could be different quality screens out there, after seeing the screen on my sister's netbook I realized that I might have to be cautious with my next purchase. Granted, I did not confirm that the reason my sister's screen looks the way it does is due to the screen itself and not color scheme/graphics card, but I know very little about the different screen technologies and how they differ in image quality and therefore can't really tell if wondering about it even makes sense or not. So what I'm asking is: should I be worried about screen quality? And if so, what technologies should I be looking for? How do they differ and which are the best ones? What are the different elements that determine the quality of a screen and which stats should I go for in each element? For the record, I'm not interested in opinions about screen size, but picture quality for lots of reading/coding.

  • iOS Guidelines for Free vs. Paid apps

    - by unforgiven3
    A few months back, I was doing some recreational reading at the iOS Dev Center, and I came across a small list of guidelines for free vs. paid apps. It included guidance along these lines: How not to promote a paid version within a free version Not displaying "placeholder" buttons in a free version that "work" in a paid version I can't remember much more than that, and I cannot find it anymore on the iOS Dev Center. It's possible I imagined it entirely, but I doubt it - does anyone have a link to this information, or have a set of guidelines for free vs. paid apps in the App Store?

  • Best way to use GIT to maintain web application template

    - by Darren
    I am a sole developer and I have a web application template that I have created in Visual Studio. I am using GIT for source control, but only on my development machine. Presently I have a master and I create branches for new features, merging them back in to the master as I complete the features. I am at a point now where I am ready to use the template for deployments, and of course I want to continue adding new features via branching/merging. My question is: what would be the typical/recommended way for me to create application deployments based on the master? Should I clone the repository into a new directory that is for a particular web application? Or should I also use branching to do project development based on the main project? The projects would never be merged back into the master. However, it would be nice if I could merge future features into the master and have the ability to incorporate them into previously completed projects if desired. For more specific details of my environment: I am using TortoiseGIT in Windows 7, Visual Studio 2012, ASP.NET Web Pages. Obviously the main differences between deployments would simply be differing pages, CSS files and jQuery scripts. I found this post as I was writing this one. In order to do this should I clone the master repository and checkout from it?

  • dependency injection example project suggestion

    - by TokenMacGuy
    I'm exploring dependency injection and trying to make the exercise as pythonic as possible; existing dependency injection frameworks seem very java-like. I've made some pretty good progress building my own framework, but I could really use a model project to validate the framework against. An ideal suggestion would be something that is hard without dependency injection, but is otherwise conceptually trivial.

  • Colleague unwilling to use unit tests "as it's more to code"

    - by m.edmondson
    A colleague is unwilling to use unit tests and instead opting for a quick test, pass it to the users, and if all is well it is published live. Needless to say some bugs do get through. I mentioned we should think about using unit tests - but she was all against it once it was realised more code would have to be written. This leaves me in the position of modifying something and not being sure the output is the same, especially as her code is spaghetti and I try to refactor it when I get a chance. So whats the best way forward for me?

  • How to use the unit of work and repository patterns in a service oriented enviroment

    - by A. Karimi
    I've created an application framework using the unit of work and repository patterns for it's data layer. Data consumer layers such as presentation depend on the data layer design. For example a CRUD abstract form has a dependency to a repository (IRepository). This architecture works like a charm in client/server environments (Ex. a WPF application and a SQL Server). But I'm looking for a good pattern to change or reuse this architecture for a service oriented environment. Of course I have some ideas: Idea 1: The "Adapter" design pattern Keep the current architecture and create a new unit of work and repository implementation which can work with a service instead of the ORM. Data layer consumers are loosely coupled to the data layer so it's possible but the problem is about the unit of work; I have to create a context which tracks the objects state at the client side and sends the changes to the server side on calling the "Commit" (Something that I think the RIA has done for Silverlight). Here the diagram: ----------- CLIENT----------- | ------------------ SERVER ---------------------- [ UI ] -> [ UoW/Repository ] ---> [ Web Services ] -> [ UoW/Repository ] -> [DB] Idea 2: Add another layer Add another layer (let say "local services" or "data provider"), then put it between the data layer (unit of work and repository) and the data consumer layers (like UI). Then I have to rewrite the consumer classes (CRUD and other classes which are dependent to IRepository) to depend on another interface. And the diagram: ----------------- CLIENT ------------------ | ------------------- SERVER --------------------- [ UI ] -> [ Local Services/Data Provider ] ---> [ Web Services ] -> [ UoW/Repository ] -> [DB] Please note that I have the local services layer on the current architecture but it doesn't expose the data layer functionality. In another word the UI layer can communicate with both of the data and local services layers whereas the local services layer also uses the data layer. | | | | | | | | ---> | Local Services | ---> | | | UI | | | | Data | | | | | | | ----------------------------> | |

  • How do people charge friends for development projects?

    - by Crashalot
    A friend has begged our consulting firm several times to build an iPhone app. We are reluctant to jeopardize the friendship and charge market rates. At the same time, we're so busy it would be imprudent not to charge fairly. We tried referring her to other shops, but she doesn't feel comfortable with anyone but us. How do people charge friends? Since I'm asking about fees, I'm also curious to know if people charge on a fixed-price basis or hourly basis? Thanks!

  • What happens differently when you add a task Asynchronously on GAE?

    - by Ben Grunfeld
    Google's doc on async tasks assumes knowledge of the difference between regular and asynchronously added tasks. add_async(task, transactional=False, rpc=None) Asynchronously add a Task or a list of Tasks to this Queue. How is adding tasks asynchronously different to adding them regularly. I.e. what is the difference between using add(task, transactional=False) and add_async(task, transactional=False, rpc=None) I've heard that adding tasks regularly blocks certain things. Any explanation of what it blocks and how, and how async tasks don't block would be greatly appreciated.

  • How to unicode Myanmar texts on Java? [closed]

    - by Spacez Ly Wang
    I'm just beginner of Java. I'm trying to unicode (display) correctly Myanmar texts on Java GUI ( Swing/Awt ). I have four TrueType fonts which support Myanmar unicode texts. There are Myanmar3, Padauk, Tharlon, Myanmar Text ( Window 8 built-in ). You may need the fonts before the code. Google the fonts, please. Each of the fonts display on Java GUI differently and incorrectly. Here is the code for GUI Label displaying myanmar texts: ++++++++++++++++++++++++ package javaapplication1; import javax.swing.JFrame; import javax.swing.JTextField; public class CusFrom { private static void createAndShowGUI() { JFrame frame = new JFrame("Hello World Swing"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); String s = "\u1015\u102F \u103C\u1015\u102F"; JLabel label = new JLabel(s); label.setFont(new java.awt.Font("Myanmar3", 0, 20));// font insert here, Myanmar Text, Padauk, Myanmar3, Tharlon frame.getContentPane().add(label); frame.pack(); frame.setVisible(true); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } } ++++++++++++++++++++++++ Outputs vary. See the pictures: Myanmar3 IMG Padauk IMG Tharlon IMG Myanmar Text IMG What is the correct form? (on notepad) Well, next is the code for GUI Textfield inputting Myanmar texts: ++++++++++++++++++++++++ package javaapplication1; import javax.swing.JFrame; import javax.swing.JTextField; public class XusForm { private static void createAndShowGUI() { JFrame frame = new JFrame("Frame Title"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JTextField textfield = new JTextField(); textfield.setFont(new java.awt.Font("Myanmar3", 0, 20)); frame.getContentPane().add(textfield); frame.pack(); frame.setVisible(true); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } } ++++++++++++++++++++++++ Outputs vary when I input keys( unicode text ) on keyboards. Myanmar Text Output IMG Padauk Output IMG Myanmar3 Output IMG Tharlon Output IMG Those fonts work well on Linux when opening text files with Text Editor application. My Question is how to unicode Myanmar texts on Java GUI. Do I need additional codes left to display well? Or Does Java still have errors? The fonts display well on Web Application (HTML, CSS) but I'm not sure about displaying on Java Web Application.

  • Multi-lingual error messages and error numbers

    - by Jon Hopkins
    So we're looking at the possibility of porting our software to support multiple languages and one of the areas we're going to have to deal with is error messages and other notifications. These obviously have to be reported to the users in their own language. Our team (largely) only speak English and even if we were all multi-lingual we're looking at selling to a wide range of countries and could never expect to have a reasonable number of people speaking all languages (we're a small company). The obvious way to get round the language issue when errors or other messages we may get asked about which are being reported is error numbers which would be consistent across language. While these are going to exist in the backend (if only as key on the error message), I'd really rather not throw them at users if we don't have to but I don't have any other solution. Anyone have any useful suggestions for alternatives?

  • What is enterprise software, exactly?

    - by good_computer
    I don't understand the difference between "normal" software and enterprise software. Even after reading these... "Enterprise Software" on Wikipedia "Enterprise Software Is Sexy Again" on Techcrunch "The Great Enterprise Software Swindle" on Coding Horror I can't really wrap my head around the real differences. Is there any difference at all between the two? Why do people say enterprise software sucks?

  • Any valid reason to Nest Master Pages in ASP.Net rather than Inherit?

    - by James P. Wright
    Currently in a debate at work and I cannot fathom why someone would intentionally avoid Inheritance with Master Pages. For reference here is the project setup: BaseProject MainMasterPage SomeEvent SiteProject SiteMasterPage nested MainMasterPage OtherSiteProject MainMasterPage (from BaseProject) The debate came up because some code in BaseProject needs to know about "SomeEvent". With the setup above, the code in BaseProject needs to call this.Master.Master. That same code in BaseProject also applies to OtherSiteProject which is just accessed as this.Master. SiteMasterPage has no code differences, only HTML differences. If SiteMasterPage Inherits MainMasterPage rather than Nests it, then all code is valid as this.Master. Can anyone think of a reason why to use a Nested Master Page here instead of an Inherited one?

  • Is there a better approach to speech synthesis than text-to-speech for more natural output? [closed]

    - by Anne Nonimus
    We've all heard the output of text-to-speech systems, and for anything but very short phrases, it sounds very machine-like. The ultimate goal of speech synthesis systems is to pass a Turing test of hearing. Clearly, the state of the art in text-to-speech has much to improve. However, speech synthesis isn't restricted to just text-to-speech systems, and I'm wondering if other approaches have been tried with better success. In other words, has there been any work done (libraries, software, research papers, etc.) on natural speech synthesis other than text-to-speech systems?

  • What guidelines do you suggest for using Objective-C Properties?

    - by adarsha
    Objective-C 2.0 introduced properties. While I personally think properties are nice addition to the language, I have seen a trend of making every instance variable as a property. Apple sample codes are no exceptions to this. I believe this is against the spirit of OOP, and since it exposes a lot more implementation details of a class to the client than they need to know. What guidelines do you suggest for the proper usage properties in Objective C?

  • Working with data and meta data that are separated on different servers

    - by afuzzyllama
    While developing a product, I've come across a situation where my group wants to store meta data for data entry forms (questions, layout, etc) in a different database then the database where the collected data is stored. This is mostly for security because we want to be able to have our meta data public facing, while keeping collected data as secure as possible. I was thinking about writing a web service that provides the meta information that the data collection program could access. The only issue I see with this approach is the front end is going to have to match the meta data with the collected data, which would be more efficient as a join on the back end. Currently, this system is slated to run on .NET and MSSQL. I haven't played around with .NET libraries running in SQL, but I'm considering trying to create logic that would pull from the web service, convert the meta data into a table that SQL can join on, and return the combined data and meta data that way. Is this solution the wrong way to approach the problem? Is there a pattern or "industry standard" way of bringing together two datasets that don't live in the same database?

  • Diff annotation tool

    - by l0b0
    Among the 11 proven practices for more effective, efficient peer code review, diff annotation seems to be the one particularly well suited to tool assistance. The article is written by the architect of SmartBear's CodeCollaborator, so he of course recommends using that. Does anyone know of any alternatives? I can't think of anything that would be even close to paper+pen+marker in pure developer efficiency when it comes to explaining a piece of code.

  • Web and Flex developer career question [closed]

    - by abhilashm86
    Possible Duplicate: should i concentrate on logical and puzzles part in programming, i want to be a web (flex)developer? I'm a computer science student and have been learning Flex and Actionscript 3.0 for 4 months. I know it's easy to program in MXML, and Actionscript 3.0 is pretty easy with bunch of classes, but when I try to code in C++ or C, I struggle, I feel I'm being inefficient and it scares me. Since I'm a student, I've no experience in developing algorithms and tough program solving? I'd like to be a web developer. Does a web developer need strong fundamentals when it comes to things such as complex algorithms and high end coding?

  • Where should SQL/DB Queries be encapsulated in a software system?

    - by Stephen Bennet
    I frequently write small applications (either web based or otherwise) that require heavy database usage. i've attempted various ways of handling where to put the actual sql queries (sort of ad-hoc ORM systems). These include: Models that build themselves up - and only allowing SQL to be inside of a model. A sort of factory style method where the models are built by a factory class that is allowed to know about SQL. A third entity that maps models based on their fields/keys into the database and generates SQL code on the fly based on this. Is there a common knowledge of which method is best? Or another way I have missed? Clearly a lot of it will be based on the context of the system itself, which for me is usually to produce lightweight tools or utility frameworks. In experimenting, I've never found any of them that feel intuitively "right" and not clunky, but I also do not want to go for a full framework such as Django or Ruby - both because the tools I create are in a variety of languages and because they usually do not warrant that level of surrounding footprint.

  • JSP Include: one large bean or bean for each include

    - by shylynx
    I want to refactor a webapp that consists of very distorted JSPs and servlets. Because we can't switch to a web framework easily we have to keep JSPs and Servlets, and now we are in doubt how to include pages into another and how to setup the use:bean-directives effectively. At the first step we want to decouple the code for the core-actions and the bean-creation into servlets. The servlets should forward to their corresponding pages, which should use the bean. The problem here is, that each jsp consists of different sub- and sub-sub-jsp that are included into another. Here is a shortend extract (because reality is more complex): head header top navigation actionspanel main header actionspanel foot footer Moreover each jsp (also the header and footer) use dynamic data. For example title and actionspanel can change on each page-reload or do have links and labels that depend on the processing by the preceding servlet. I know that jsp-include-directives should only be used for static content und should be avoided for dynamic content. But here we have very large pages, that consist of many parts. Now the core questions: Should I use one big bean for each page, so that each bean holds also data for header and footer beside its core data, so that each subsequent included jsp uses the same bean-directive? For example: DirectoryJSP <- DirectoryBean CompareJSP <- CompareBean Or should I use one bean for each jsp, so that each bean only holds the data for one jsp and its own purpose. For example: DirectoryJSP <- DirectoryBean HeaderJSP <- HeaderBean FooterJSP <- FooterBean CompareJSP <- CompareBean HeaderJSP <- HeaderBean FooterJSP <- FooterBean In the second case: should the subsequent beans be a member of the corresponding parent bean, so that only the parent bean is attached as attribute to the request? Or should each bean attached to the request?

  • When to use abstract classes instead of interfaces and extension methods in C#?

    - by Gulshan
    "Abstract class" and "interface" are similar type of ideas, while interface being more abstract. One need of abstract classes was to provide method implementations for the derived classes. But in C#, that need has also been reduced by lately introduced extension methods. So, in C#, when should we use abstract classes instead of using interfaces and extension methods associated with the interface? And now, we can use 'Properties' in interfaces also. A notable example of interface+ extension methods is the Heavily used IEnumerable and it's helper methods. You use Linq and it's all by this extension methods!

  • In WPF, should I base my converters on types or use-cases?

    - by user1013159
    I'm looking for some advice on how to write my WPF value converters. The way I'm currently writing them, they are very specific, like (bool?,bool) = Brush, i.e. I'm writing each converter for a specific use case, in this case, the Brush is bound to an indicator showing equality information between the bool? and the bool. This obviously makes re-use very hard and I end up with a quite large list of converters. Should I strive to write my converters in a more general way? Can I?

  • Understanding hand written lexers

    - by Cole Johnson
    I am going to make a compiler for C (C99; I own the standards PDF), written in C (go figure) and looking up on how compilers work on Wikipedia has told me a lot. However, after reading up on lexers has confused me. The Wikipedia page states that: the GNU Compiler Collection (gcc) uses hand-written lexers I have tried googling what a hand written lexer and have come up with nothing except for "making a flowchart that describes how it should function", however, isn't that how all software development should be done? So my question is: "What is a hand written lexer?"

  • Teaching logical/analytical thinking

    - by Joshua
    I have been trial running a club in which I teach programming for the past year and while they have progressed what they really lack is the most fundamental concept to programming, analytical thinking. As I now approach the second year of teaching to the children (aged 12 - 14) I am now realising that before I begin teaching them the syntax and how to actually program an app (or what they would rather, a game) I need to introduce them to analytical thinking first. I have already found Scratch and similar things such as Light-Bot and will most certainly be using the, to teach them how to implement their logical thinking but what I really need are some tips or articles on how to teach analytical thinking itself to children aged 12 - 14. What I'm looking for are some ideas on how to teach the kind of thinking that these kids will need in order to get them into programming, whether that be analytical, logical or critical. How and what should I teach them relating to the way their minds need to be wired when programming solutions to problems?
