  • Looking for new language and new technology [closed]

    - by Basim
    back when Microsoft relased .Net in 2002 or whatever, when I look at that time I say to myself what I if I picked one of Microsoft language in that time and still work on it, of course I will be professional by now. I am looking for a new language that is going up and will be big thing in the next 5-10 years, so in that time i can see the big picture and I know that I'm one of the few people who started from the beginning with X programming language or technology. My interest is web development.

  • Remote Debugging

    - by Pemdas
    Obviously, the easiest way to solve a bug is to be able to reproduce it in house. However, sometimes that is not practical. For starters, users are often not very good at providing you with useful information. Costumer Service: "what seems to be the issue?" User: "It crashed!" To further compound that, sometimes the bug only occurs under certain environmentally conditions that can not be adequately replicated in house. With that in mind, it is important to build some sort of diagnostic framework into your product. What type of solutions have you seen or used in your experience? Logging seems to be the predominate method, which makes sense. We have a fairly sophisticated logging frame work in place with different levels of verbosity and the ability to filter on specific modules (actually we can filter down to the granularity of a single file). Error logs are placed strategically to manufacture a pretty good representation of a stack trace when an error occurs. We don't have the luxury of 10 million terabytes of disk space since I work on embedded platforms, so we have two ways of getting them off the system: a serial port and a syslog server. However, an issue we run into sometimes is actually getting the user to turn the logs on. Our current framework often requires some user interaction.

  • Who should control navigation in an MVVM application?

    - by SonOfPirate
    Example #1: I have a view displayed in my MVVM application (let's use Silverlight for the purposes of the discussion) and I click on a button that should take me to a new page. Example #2: That same view has another button that, when clicked, should open up a details view in a child window (dialog). We know that there will be Command objects exposed by our ViewModel bound to the buttons with methods that respond to the user's click. But, what then? How do we complete the action? Even if we use a so-called NavigationService, what are we telling it? To be more specific, in a traditional View-first model (like URL-based navigation schemes such as on the web or the SL built-in navigation framework) the Command objects would have to know what View to display next. That seems to cross the line when it comes to the separation of concerns promoted by the pattern. On the other hand, if the button wasn't wired to a Command object and behaved like a hyperlink, the navigation rules could be defined in the markup. But do we want the Views to control application flow and isn't navigation just another type of business logic? (I can say yes in some cases and no in others.) To me, the utopian implementation of the MVVM pattern (and I've heard others profess this) would be to have the ViewModel wired in such a way that the application can run headless (i.e. no Views). This provides the most surface area for code-based testing and makes the Views a true skin on the application. And my ViewModel shouldn't care if it displayed in the main window, a floating panel or a child window, should it? According to this apprach, it is up to some other mechanism at runtime to 'bind' what View should be displayed for each ViewModel. But what if we want to share a View with multiple ViewModels or vice versa? So given the need to manage the View-ViewModel relationship so we know what to display when along with the need to navigate between views, including displaying child windows / dialogs, how do we truly accomplish this in the MVVM pattern?

  • How to increase the bus factor and specialize at the same time?

    - by bizso09
    In agile pair programming it is recommended to switch pairs every now and then so as to increase the bus factor of the team. That means, most people in the team should work on different parts of the system at different times so that everyone has an understanding of it. Now it is impssible that everyone has an expert level of understanding of each part of the system. That's because people are urged to specialize in one area of expertise. If you are an expert database admin, what's the point of working on the user interface of the system when you switch pairs? You will not be able to do such a high quality job as someone who has extensive experience in UI design. How can you increase the bus factor and make sure that you have specialization in your team?

  • What's the most effective way to perform code reviews?

    - by Paddyslacker
    I've never found the ideal way to perform code reviews and yet often my customers require them. Each customer seems to do them in a different way and I've never felt satisfied in any of them. What has been the most effective way for you to perform code reviews? For example: Is one person regarded as the gatekeeper for quality and reviews the code, or do the team own the standard? Do you do review code as a team exercise using a projector? Is it done in person, via email or using a tool? Do you eschew reviews and use things like pair programming and collective code ownership to ensure code quality?

  • What is the name of this tree?

    - by Daniel
    It has a single root and each node has 0..N ordered sub-nodes . The keys represent a distinct set of paths. Two trees can only be merged if they share a common root. It needs to support, at minimum: insert, merge, enumerate paths. For this tree: The +-------+----------------+ | | | cat cow dog + +--------+ + | | | | drinks jumps moos barks + | milk the paths would be: The cat drinks milk The cow jumps The cow moos The dog barks It's a bit like a trie. What is it?

  • Is listing developer's full names in splash screen or about box still a widely spread and desirable practice?

    - by Pierre 303
    Just like in the closing credits of movies, some software vendors list the full names of the team that worked on the piece of software you are using. They are usually displayed in the splash screen (Photoshop) ... or in the about box (Traktor). In the demoscene, it is a mandatory practice, like in the movie industry. How do you see that in your own software? Is there any reason why not doing it? Is there any reason encouraging companies to do it?

  • In which object should I implement wait()/notify()?

    - by Christopher Francisco
    I'm working in an Android project with multithreading. Basically I have to wait to the server to respond before sending more data. The data sending task is delimited by the flag boolean hasServerResponded so the Thread will loop infinitely without doing anything until the flag becomes true. Since this boolean isn't declared as volatile (yet), and also looping without doing anything wastes resources, I thought maybe I should use AtomicBoolean and also implement wait() / notify() mechanism. Should I use the AtomicBoolean object notify() and wait() methods or should I create a lock Object?

  • Why do people use programming books?

    - by Alex Hope O'Connor
    I find that when someone asks what is the best way to learn how to program, people usually provide them with references to a bunch texts written by various authors. However I don't believe many people at all learn to program from books? I find that they are usually faced with a challenge and then use programming as tool to overcome it. For example I 'got into' programming because I wanted to start a server for a game I was playing, so I googled and read through the support for that particular server and now I am a employed software engineer, using only the skills I developed (and then further developed) by coding C# scripts for a not very popular server package. So my question is, do people generally find it easier to learn from these books? I know I have looked at a few of them and found them far too 'dry' to encourage me to finish it.

  • To refund or not to refund this client?

    - by Mahalia Samuels
    I'd really appreciate your advice on an ongoing project. I presented my client with a proposal and design samples which he approved, and he paid in full instead of the 50% upfront deposit as I'd given him a generous discount. He was then slow in furnishing me with some of the content, but once we did, he expected the website to be finished immediately which was not possible. Because he needed it done urgently, we agreed to try to get it done about 10 working days after the content was provided, but the developer who was helping me let me down. The next week, I completed the website myself and uploaded it to the server on a Friday afternoon. He then calls and texts me on following Sunday while I'm at church to say it's not online (there was probably a problem with his browser). The next morning, I received an email from him demanding a full refund within two days because he couldn't see the website (even though it was live, and I tested it on multiple browsers, a different computer and my phone), and he called me shouting at me because he couldn't access it. Finally when he was able to access it, he was unhappy with a certain detail regarding the slideshow which I began fixing and which was done the next day. He then referred me to another website and said he wanted it to look similar but not identical to it in terms of the layout. He also now wanted to add more features which were not in the original design. I got a designer to work on a new design which I sent to him for review, which if approved would be completed by 15 October, and he approved it last Thursday. He then called me yesterday to say that he wanted to change the design - he only approved it out of impatience. He now wants the website to be more similar to the other website he referred me to and he wants it done before the 15th! Then, he says to me that other people have done websites for him in three days - website's he's complained to me about for lacking dimension because they were just premium themes, whereas we'd designed and coded from scratch. I'm thinking of finishing the website but refunding him in full (or at least the refundable 50%) less domain registration and other non-refundable amounts, just to avoid further escalation of this matter and having him call me next week and say he wants to change it again. These are the applicable terms and conditions as laid out in the agreement: Total amount due for this project is Amount A. Client shall pay Consultant a deposit of Amount B (50% of total amount due for project) in advance before any work commences on the Project. The balance is due within 7 working days of completion of project. Deposit is non-refundable. Should client opt to host elsewhere, applicable transferral fee of Amount C will apply. Estimated project completion time frame is 14 to 30 days from the date Client furnishes Consultant with Brief and all other required media and data, provided that Client has made payment to secure the project. Consultant will make every effort to meet agreed upon due dates. The Client should be aware that failure to submit required information or materials, or last minute changes and excessive changes may cause subsequent delays. Client delays could result in significant delays in delivery of finished work. Major changes in client input or direction or brief will be charged at normal rates. Any work the Client wishes Consultant to create, which is not specified in the attached Proposal will be considered an additional service. Client agrees to pay Consultant for any additional expenses or additional services not included in the attached quotation and proposal if requested by the Client. Web design credit in the name of the Consultant, and link to Consultant’s website shall be placed on the footer of the final Website. Either party may terminate this Agreement by giving 7 days written notice to the other of such termination. In the event that Work is postponed or terminated at the request of the Client, Consultant shall have the right to bill pro rata at full rates for work completed through the date of that request, while reserving all rights under this Agreement. If additional payment is due, this shall be payable within seven days of the Client's written notification to stop work. In the event of termination, the Client shall also pay any expenses incurred by Consultant and the Consultant shall own all rights to the Work. Advice please?

  • Web application deployment and Dependencies

    - by Reith
    I have a free software web application that using other free software scripts for appearance. I have trouble to decide whether should I copy source code of used scripts to my project main repository or list them as dependencies and ask user to install them himself? Since some of scripts solving browser compatibilities issues and I'm not a good web designer (i hate to check my web site on IE to see compatibility) using the newest version of scripts is preferable and second solution works here. But it has problem with scripts aren't backward-compatible with versions I've used them for development. Maybe another method is well-known for this issues that I don't know them.

  • Where should I handle fatal exceptions

    - by Puckl
    For example, I have a controller that loads a file and hands it over to the processing. Should I handle the exception in the file loader and return Null if something is wrong, or should I throw the exception and handle it in the controller? Without the file the rest of the program can´t work. Where should I handle a exception that shuts down the program properly? I want to shut down an Android application properly.

  • What would you think of a job based on mostly doing the proof of concept?

    - by davsan
    I'm working as a developer in a small software company whose main job is interfacing between separate applications, like between a telephony system and an environment control system, between IP TVs and hospitality systems, etc...And it seems like I am the candidate for a new job title in the company, as the person who does the proof of concept of a new interfacing project and does some R&D for prototyping. What do you think the pros and cons of such a job would be, considering mainly the individual progress/regress of a person as a software engineer? And what aspects would you consider essential in a person to put him/her in such a job position?

  • An alternative to multiple inheritance when creating an abstraction layer?

    - by sebf
    In my project I am creating an abstraction layer for some APIs. The purpose of the layer is to make multi-platform easier, and also to simplify the APIs to the feature set that I need while also providing some functionality, the implementation of which will be unique to each platform. At the moment, I have implemented it by defining and abstract class, which has methods which creates objects that implement interfaces. The abstract class and these interfaces define the capabilities of my abstraction layer. The implementation of these in my layer should of course be arbitrary from the POV view of my application, but I have done it, for my first API, by creating chains of subclasses which add more specific functionality as the features of the APIs they expose become less generic. An example would probably demonstrate this better: //The interface as seen by the application interface IGenericResource { byte[] GetSomeData(); } interface ISpecificResourceOne : IGenericResource { int SomePropertyOfResourceOne {get;} } interface ISpecificResourceTwo : IGenericResource { string SomePropertyOfResourceTwo {get;} } public abstract class MyLayer { ISpecificResourceOne CreateResourceOne(); ISpecificResourceTwo CreateResourceTwo(); void UseResourceOne(ISpecificResourceOne one); void UseResourceTwo(ISpecificResourceTwo two); } //The layer as created in my library public class LowLevelResource : IGenericResource { byte[] GetSomeData() {} } public class ResourceOne : LowLevelResource, ISpecificResourceOne { int SomePropertyOfResourceOne {get{}} } public class ResourceTwo : ResourceOne, ISpecificResourceTwo { string SomePropertyOfResourceTwo {get {}} } public partial class Implementation : MyLayer { override UseResourceOne(ISpecificResourceOne one) { DoStuff((ResourceOne)one); } } As can be seen, I am essentially trying to have two inheritance chains on the same object, but of course I can't do this so I simulate the second version with interfaces. The thing is though, I don't like using interfaces for this; it seems wrong, in my mind an interface defines a contract, any class that implements that interface should be able to be used where that interface is used but here that is clearly not the case because the interfaces are being used to allow an object from the layer to masquerade as something else, without the application needing to have access to its definition. What technique would allow me to define a comprehensive, intuitive collection of objects for an abstraction layer, while their implementation remains independent? (Language is C#)

  • Does heavy JavaScript use adversely impact Googleability?

    - by A T
    I've been developing the client-side for my web-app in JavaScript. The JavaScript can communicate with my server over REST (HTTP)[JSON, XML, CSV] or RPC (XML, JSON). I'm writing writing this decoupled client in order to use the same code for both my main website and my PhoneGap mobile apps. However recently I've been worrying that writing the website with almost no static content would prevent search-engines (like Google) from indexing my web-page. I was taught about this restriction about 4 years ago, which is why I'm asking here, to see if this restriction is still in-place. Does heavy JavaScript use adversely impact Googleability?

  • How should I name the language data files?

    - by Ron
    Recently I decided to add some translations to my program. I wonder how I should name the language files? in the culture's name of the language (example: english = en, french = fr, italian = it, etc...) in the name of the language [in english] (example: english = english, french = french, italian = italian, etc..) I know you'll choose the second way because you dont have to detect which filename it is because both have the same name. But the problem is this - I show the name of the languages in its langauge (example: english = english, french = française, italian = italiano, etc..) so I still need to detect which filename it is. The main question is which way I should choose? the name of the language in english or the culture name? and why?... Thanks!

  • Metaobject protocol:Why is it known as an important concept

    - by sushant
    Metaobject protocol is protocol for metaobjects in a programming languages. Although I understand it on simple terms, I want to know the reason and a summary of real world usage patterns of this protocol. So, why exactly is metaobject and more importantly metaobject protocol is such a good idea. I want to know the problem which led to its evolution and also, its high power usage. Opinions as well as general overview/description/alternate explanations are also welcome.

  • CQRS applicability when some commands need to block the UI

    - by regularfry
    I am working on an app which I would dearly love to transition from a fairly traditional layered architecture to CQRS, for a number of reasons, not least fo which is that having a robust event log will make adding a couple of feature requests I can see barrelling towards me trivial to accomodate. Now, I have a conceptual problem: of around 40 commands the user can initiate, there are three which the user needs to be sure have successfully completed before the UI lets them do anything else. Everything else fits into the "submit a request, query for success later" model, except for these three commands. How is this handled in CQRS-land? Do I separate the three blocking commands to effectively a third service, so I have Commands, Queries, and BlockingCommands? Do I have a two-stage event processor with an in-request blocking first stage which only gets used for the blocking commands? Does the existence of these three commands mean that the whole idea of applying CQRS is invalid? Should I just pretend they aren't blocking and poll for success in the UI? I'm sure this must come up on other projects, how is it usually handled?

  • How does one handle sensitive data when using Github and Heroku?

    - by Jonas
    I am not yet accustomed with the way Git works (And wonder if someone besides Linus is ;)). If you use Heroku to host you application, you need to have your code checked in a Git repo. If you work on an open-source project, you are more likely going to share this repo on Github or other Git hosts. Some things should not be checked in the public repo; database passwords, API keys, certificates, etc... But these things still need to be part of the Git repo since you use it to push your code to Heroku. How to work with this use case? Note: I know that Heroku or PHPFog can use server variables to circumvent this problem. My question is more about how to "hide" parts of the code.

  • Boss solution vs Developer solution

    - by mahen23
    The problem: When we were sending newsletters to customers, there was no way to confirm if the customer already received the mail. So the boss decided to implement this idea: Boss's Idea: Each time mail was being sent, do an INSERT in a db with the title of the newsletter being sent and the email address which is receving the email address. To ensure that any email address does not receive the same email twice, do a SELECT in the table and find the title of the newsletter being sent: if (title of newsletter is found) { check to see of the email we are sending mail to is already present. if it does, do not send mail } else { send mail } MY idea: create a column called unique and mark it as UNIQUE. Each time mail was being sent, concatenate email + newsletter id and record it in the UNIQUE row. The next time we do a "mysql_affected_rows" check to see if our INSERT was successful, we send the mail, else, there is already a duplicate and no need to send it.

  • Scheme vs Haskell for an Introduction to Functional Programming?

    - by haziz
    I am comfortable with programming in C and C#, and will explore C++ in the future. I may be interested in exploring functional programming as a different programming paradigm. I am doing this for fun, my job does not involve computer programming, and am somewhat inspired by the use of functional programming, taught fairly early, in computer science courses in college. Lambda calculus is certainly beyond my mathematical abilities, but I think I can handle functional programming. Which of Haskell or Scheme would serve as a good intro to functional programming? I use emacs as my text editor and would like to be able to configure it more easily in the future which would entail learning Emacs Lisp. My understanding, however, is that Emacs Lisp is fairly different from Scheme and is also more procedural as opposed to functional. I would likely be using "The Little Schemer" book, which I have already bought, if I pursue Scheme (seems to me a little weird from my limited leafing through it). Or would use the "Learn You a Haskell for Great Good" if I pursue Haskell. I would also watch the Intro to Haskell videos by Dr Erik Meijer on Channel 9. Any suggestions, feedback or input appreciated. Thanks. P.S. BTW I also have access to F# since I have Visual Studio 2010 which I use for C# development, but I don't think that should be my main criteria for selecting a language.

  • Real performance of node.js

    - by uther.lightbringer
    I've got a question concerning node.js performance. There is quite lot of "benchmarks" and a lot of fuss about great performance of node.js. But how does it stand in real world? Not just process empty request at high speed. If someone could try to compare this scenario: Java (or equivalent) server running an application with complex business logic between receiving request and sending response. How would node.js deal with it? If there was need for a lot of JavaScript processing on server side, is node.js really so fast that it can execute JavaScript, and stand a chance against more heavyveight competitors?

  • How to connect to a WCF service using IP of the host machine where the service is hosted?

    - by Kumar
    I have a secured WCF service (https://<MachineName>:sslport/services) self hosted in a machine. Different instances of same service are deployed in differnt machines. From a client app, I am able to connect to theses services through code, i.e. using ChannelFactory() with the same endpoint address. But if I try to access the service using the endpoint address as https://<ipAddress>:sslport/services replacing machines name with machine IP address, I am getting some error stating "could not establish trust relationship". I know this is an error caused by SSL certificate that it could not establish a trust relationship. Are there any settings or any possibilities to make this work?

  • What is the best way to keep track of the median?

    - by Steven Mou
    I read a question in one book: Numbers are randomly generated and stored into an (expanding) array, How would you keep track of the median? There are two data structures can solve the problem. One is the balanced binary tree, the other is two heaps which keep trace of the biggest half and the smallest half of the elements. I think these two solutions has the same running time as O(n lg n), but I am not sure of my judgement. In your opinions, What is the best way to keep track of the median?
