• Methods of learning / teaching programming

  - by Mark Avenius

  When I was in school, I had a difficult time getting into programming because of a catch-22 in the learning process: I didn't know how to write anything because I didn't know what keywords and commands meant. For example (as a student, I would think), "what does this using namespace std; thing do anyway? I didn't know what keywords and commands meant because I hadn't written anything. This basically led me to spending countless long night cursing the compiler as I made minor tweaks to my assignments until they would compile (and hopefully perform whatever operation they were supposed to). Is there a teaching/learning method that anyone uses that gets around this catch-22? I am trying to make this non-argumentative, which is why I don't want to know the 'best' method, but rather which methods exist.

• Student wanting to go to a developer conference

  - by Jamie Keeling

  I'm a 21 year old student in my last year of University, and I am looking for information about developer conferences. I live in Derby (United Kingdom) and there's not (As far as I know) many conferences local to where I live. I do have a car at my disposal so travelling shouldn't be a problem. I was hoping somebody could recommend the best way to go about finding and attending a conference, which one is probably the best to go to and what kind of things I'd need to know and take beforehand. I've done a couple of Google searches and searched SO itself but nothing specific to my needs was found. Note: I'm primarily a C# developer using WPF and WinForms but I'm open to pretty much anything.

• What is so good about Linux? [closed]

  - by Chris Bridgett

  Self-explanatory question title. I've only ever used Windows OS's (except Mac OSX at friends etc, years ago occasionally) and when diving into the world of programming, Linux is a name that is coming up every other tutorial or article. All my web hosts run Linux and a lot of programming literature covers how to go about various tasks on Linux as well as Windows, but other than the odd raving I've read years ago about Linux being less resource-intensive, I haven't really given it much thought. Any article I read about Linux and whether it should be used for... 'regular' use, it's shunned since any windows applications I'm familiar with will usually require the windows API and there's no end of 'hacking' to get various programs working on Linux. As far as I understand a GUI is optional on Linux too? This all sounds very noobish I'm sure, but we all start somewhere, so: What is Linux good for? What should Linux be used for?

• Any tips for designing the invoicing/payment system of a SaaS?

  - by Alexandru Trandafir Catalin

  The SaaS is for real estate companies, and they can pay a monthly fee that will offer them 1000 publications but they can also consume additional publications or other services that will appear on their bill as extras. On registration the user can choose one of the 5 available plans that the only difference will be the quantity of publications their plan allows them to make. But they can pass that limit if they wish, and additional payment will be required on the next bill. A publication means: Publishing a property during one day, for 1 whole month would be: 30 publications. And 5 properties during one day would be 5 publications. So basically the user can: Make publications (already paid in the monthly fee, extra payment only if it passes the limit) Highlight that publication (extra payment) Publish on other websites or printed catalogues (extra payment) Doubts: How to handle modifications in pricing plans? Let's say quantities change, or you want to offer some free stuff. How to handle unpaid invoices? I mean, freeze the service until the payment has been done and then resume it. When to make the invoices? The idea is to make one invoice for the monthly fee and a second invoice for the extra services that were consumed. What payment methods to use? The choosen now is by bank account, and mobile phone validation with a SMS. If user doesn't pay we call that phone and ask for payment. Any examples on billing online services will be welcome! Thanks!

• Where should I draw the line between unit tests and integration tests? Should they be separate?

  - by Earlz

  I have a small MVC framework I've been working on. It's code base definitely isn't big, but it's not longer just a couple of classes. I finally decided to take the plunge and start writing tests for it(yes, I know I should've been doing that all along, but it's API was super unstable up until now) Anyway, my plan is to make it extremely easy to test, including integration tests. An example integration test would go something along these lines: Fake HTTP request object - MVC framework - HTTP response object - check the response is correct Because this is all doable without any state or special tools(browser automation etc), I could actually do this with ease with regular unit test frameworks(I use NUnit). Now the big question. Where exactly should I draw the line between unit tests and integration tests? Should I only test one class at a time(as much as possible) with unit tests? Also, should integration tests be placed in the same testing project as my unit testing project?

• how to learn ios game development using swift.. good starting point?

  - by hamobi

  I've published a simple app on the app store using objective-c. That was a good learning experience but I never grew to love the language. Later on I jumped into learning cocos2d in order to begin developing a game.. but objective-c always seemed really cumbersome to write. Eventually I put my project aside. Now that swift has come out.. It has made me think about developing games again.. I know that xcode has some project types geared towards game development, but since I'm a beginner in this area I really need some hand holding (books / tutorials) to get started. Cocos2d seems like its really stuck in that objective-c world. What's the best way for a beginner to learn game development using swift?

• Securing iOS or Android Backend API

  - by El Guapo

  I have an application that I am writing for both iOS and Android; this application will be served by a ReSTFUL API running on a cluster of servers on "the internets". I am curious how the rest of the world is going about securing their APIs so only specific applications running on iOS or Android can use these APIs. I could go the same route as other OAuth providers by providing a key/secret combination (2-legged OAuth), however, what do I do if I ever have to change these keys??? Do I create a new key/secret for every person that downloads the app???

• MVC: Why put the business logic in the model? What happens when I've multiple types of storage?

  - by Steffen Winkler

  I always thought that the business logic has to be in the controller and that the controller, since it is the 'middle' part, stays static and that the model/view have to be capsuled via interfaces, that way you could change the business logic without affecting anything else, program multiple Models (one for each database/type of storage) and a dozens of views (for different platforms for example). Now I read in this question that you should always put the business logic into the model and that the controller is deeply connected with the view. To me, that doesn't really make sense and implies that each time I want to have the means of supporting another database/type of storage I've to rewrite my whole model including the business logic. And if I want another view, I've to rewrite both the view and the controller. May someone explain why that is or if I went wrong somewhere? Currently, that whole thing doesn't really make sense to me.

• Newbie worried about CASE tool.

  - by Jason Evans

  Hi there. I'm looking for some guidance on CASE tools and whether my concerns are valid. Recently I was in a meeting between my employer and an external software company which have a CASE tool currently in beta. They demonstrated this tool to us, showing how you build a UML model in Enterprise Architect (or something like it) and then, through their tool, that UML model is transformed into a Visual Studio project, with C# files, stored procedures for SQL Server, code for the data layer, WCF stuff, logging code and allsorts. Now, admittedly, I don't see the point in this, as in I'm not convinced it will save that much time (plus it feels like overkill). The tool authors said that a trial of the tool at another company had saved a team there 5 weeks of development time (from 6 weeks down to about 1 week) using this tool. I find the accuracy of that estimate hard to believe. My main concern is whether using this tool is going slow down my productivity. For example - Say I have a UML model which I built a VS solution from. Now, I want to rename a class method to something else; will this mean having to update the UML model first and then rebuilding the code? Is this how case tools normally work? Something I will need to check with the authors is the structure of the generated VS solution. I like the Domain Driven Design way of project structure - Infrstructure, Services, Model, etc. I doubt very much this tool will do that. Also, I've been playing around with Entity Framework Code First and think it's a great way to build the data model. I have nice repositories, unit of work classes and other design patterns that work well with EF. I have data anootations and stuff like that working great. By not having EF (the CASE tool uses it's own data layer code) I'm concerned that this tool's data layer code might not be a nice to integrate in the UoW pattern, repositories, etc. This I will need to verify when I get a closer look at the generated code. What are other people's experiences with CASE tools? Am I being paranoid about nothing? Am I being unfair - are my negativities unfounded? EDIT: I like to use TDD/BDD for building my code, and using a CASE tool looks like it will make this difficult. Again, any feedback on this would be great. Cheers. Jas.

• When using method chaining, do I reuse the object or create one?

  - by MainMa

  When using method chaining like: var car = new Car().OfBrand(Brand.Ford).OfModel(12345).PaintedIn(Color.Silver).Create(); there may be two approaches: Reuse the same object, like this: public Car PaintedIn(Color color) { this.Color = color; return this; } Create a new object of type Car at every step, like this: public Car PaintedIn(Color color) { var car = new Car(this); // Clone the current object. car.Color = color; // Assign the values to the clone, not the original object. return car; } Is the first one wrong or it's rather a personal choice of the developer? I believe that he first approach may quickly cause the intuitive/misleading code. Example: // Create a car with neither color, nor model. var mercedes = new Car().OfBrand(Brand.MercedesBenz).PaintedIn(NeutralColor); // Create several cars based on the neutral car. var yellowCar = mercedes.PaintedIn(Color.Yellow).Create(); var specificModel = mercedes.OfModel(99).Create(); // Would `specificModel` car be yellow or of neutral color? How would you guess that if // `yellowCar` were in a separate method called somewhere else in code? Any thoughts?

• Pass FORTRAN variable to Python [migrated]

  - by Matthew Bilskie

  I have a FORTRAN program that is called from a Python script (as an ArcGIS tool). I need to pass an array, Raster_Z(i,j), from FORTRAN to python. I have read about the Python subprocess module; however, I have not had much luck in understanding how to do this with FORTRAN. All examples I have found involve simple unix command line calls and not actual programs. Has anyone had any experience in passing a variable from FORTRAN to Python via a memory PIPE? Thank you for your time.

• Intellectual Property for in house development

  - by Kyle Rogers

  My company is a sub contractor on a major government contract. Over the past 5 years we've been developing in house applications to help support our company and streamline our work. Apparently in 2008 our president of the company at that time signed a continuation of services contract with the company we subcontract with on this project. In the contract amendment various things were discussed such as intellectual property and the creation of new and existing tools. The contract states that all the subcontractor's tools/scripts/etc... become the intellectual property of the main contractor holder. Basically all tools that were created in support of the project which we work on are no longer ours exclusively and they have rights to them. My company really doesn't do software development specifically but because of this contract these tools helped tremendously with our daily tasking. Does my company have any sort of recourse or actions to help keep our tools? My team of developers were completely unaware of any of these negotiations and until recently were kept in the dark about the agreements that were made. Do we as developers have any rights to the software? Since our company is not a software development shop, we have created all these tools without any sort of agreements or contracts within the company stating that we give our company full rights to our creations? I was reading an article by Joel Spolsky on this topic and was just wonder if there is any advice out there to help assist us? Thank you Joel Spolsky's Article

• As a solo programmer, of what use can Gerrit be?

  - by s.d

  Disclaimer: I'm aware of the questions How do I review my own code? and What advantages do continuous integration tools offer on a solo project?. I do feel that this question aims at a different set of answers though, as it is about a specific software, and not about general musings about the use of this or that practice or tech stack. I'm a solo programmer for an Eclipse RCP-based project. To be able to control myself and the quality of my software, I'm in the process of setting up a CSI stack. In this, I follow the Eclipse Common Build Infrastructure guidelines, with the exception that I will use Jenkins rather than Hudson. Sticking to these guidelines will hopefully help me in getting used to the Eclipse way of doing things, and I hope to be able to contribute some code to Eclipse in the future. However, CBI includes Gerrit, a code review software. While I think it's really helpful for teams, and I will employ it as soon as the team grows to at least two developers, I'm wondering how I could use it while I'm still solo. Question: Is there a use case for Gerrit that takes into account solo developers? Notes: I can imagine reviewing code myself after a certain amount of time to gain a little distance to it. This does complicate the workflow though, as code will only be built once it's been passed through code review. This might prove to be a "trap" as I might be tempted to quickly push bad code through Gerrit just to get it built. I'm very interested in hearing how other solo devs have made use of Gerrit.

• Securing Back End API for Mobile Applications

The application is a social-based game that will allow the user to interact with other "participants" in the game based on location, achievements, etc. The API will provide the following functions: -Questions, Quests, etc -Profile Management -User Interaction -Possible Social Interaction Once the app gains traction I plan on opening up the API ala Facebook, Twitter, etc. Which is easy enough, I plan on implementing an OAuth Server and whatnot. However, I want to make sure, during this phase, that only people who are using the application can access and use the API.

• How to introduce versioning for questions on Stack*? [closed]

  - by András Szepesházi

  What today is the best answer for any given question, yesterday was not available and tomorrow will be obsolete. Especially when we're talking about software development. Here is an example for you (there must be thousands, this one is absolutely imaginary): Q: What is the best way to implement autocomplete in javascript? A: (2000) Whut? A: (2007) Write a custom ajax function, display the results after processing A: (2011) Use this plugin: http://jqueryui.com/demos/autocomplete/ (nono, I'm not a jQuery affiliate, actually I prefer MooTools) What would be your recommendation to introduce versioning for Stack Exchange questions and answers? Is there a need at all for that?

• Logical progressions through the job market

  - by Philluminati

  I'm 5 years out of a unrecognised university where I did Software Engineering. First job was VB.NET, one job was Python, Linux and Web development. I feel cast as a web developer. I'd love a role doing C but no one is interested in juniors if the applicant hasn't got 3 years of C development experience already. I've done some C and a drop of open source coding but I'll never have the confidence to convince someone I know absolutely what I'm doing. Do I just spend more and more time letting life pass me by as I sit in my room on a friday night writing a C problem "for the sake of learning more C" Basically I'm just not sure I want to continue my career if it's going to involve nothing but high level, machine abstracted, business logic and as interested as I am in low level development and enjoy reading books by Taunembaum I struggle to see how I can make the jump and I just feel life would be easier if I got a job in a cafe in Amsterdam rolling spliffs for customers. My ideal job, being a paid member of the Fedora development team seems so far away, without anyone to pay me to learn the skills to get there, and the only way would be to literally spend weeks and weeks of my life contributing code without recognition for free and without any guarentees at the end. Not that I've contributed anything at all so far. Are there any career paths that are logically set out so that jumping between roles is "correctly" incremental and where hard work and learning does eventually lead to the kind of places I might want to go? [ and also getting paid at the same time? ]

• Should I choose Doctrine 2 or Propel 1.5/1.6, and why?

  - by Billy ONeal

  I'd like to hear from those who have used Doctrine 2 (or later) and Propel 1.5 (or later). Most comparisons between these two object relational mappers are based on old versions -- Doctrine 1 versus Propel 1.3/1.4, and both ORMs went through significant redesigns in their recent revisions. For example, most of the criticism of Propel seems to center around the "ModelName Peer" classes, which are deprecated in 1.5 in any case. Here's what I've accumulated so far (And I've tried to make this list as balanced as possible...): Propel Pros Extremely IDE friendly, because actual code is generated, instead of relying on PHP magic methods. This means IDE features like code completion are actually helpful. Fast (In terms of database usage -- no runtime introspection is done on the database) Clean migration between schema versions (at least in the 1.6 beta) Can generate PHP 5.3 models (i.e. namespaces) Easy to chain a lot of things into a single database query with things like useXxx methods. (See the "code completion" video above) Cons Requires an extra build step, namely building the model classes. Generated code needs rebuilt whenever Propel version is changed, a setting is changed, or the schema changes. This might be unintuitive to some and custom methods applied to the model are lost. (I think?) Some useful features (i.e. version behavior, schema migrations) are in beta status. Doctrine Pros More popular Doctrine Query Language can express potentially more complicated relationships between data than easily possible with Propel's ActiveRecord strategy. Easier to add reusable behaviors when compared with Propel. DocBlock based commenting for building the schema is embedded in the actual PHP instead of a separate XML file. Uses PHP 5.3 Namespaces everywhere Cons Requires learning an entirely new programming language (Doctrine Query Language) Implemented in terms of "magic methods" in several places, making IDE autocomplete worthless. Requires database introspection and thus is slightly slower than Propel by default; caching can remove this but the caching adds considerable complexity. Fewer behaviors are included in the core codebase. Several features Propel provides out of the box (such as Nested Set) are available only through extensions. Freakin' HUGE :) This I have gleaned though only through reading the documentation available for both tools -- I've not actually built anything yet. I'd like to hear from those who have used both tools though, to share their experience on pros/cons of each library, and what their recommendation is at this point :)

• First ASP.NET WebForms application completed, should I jump into MVC now?

  - by farhad

  I just finished my first Asp.net intranet application using WebForms, and now I am considering learning MVC. My questions are: I mainly use LINQ for CRUD purposes instead of SQL, should I also learn hard coded SQL or just stick to LINQ EF? Is it a good idea to start learning MVC now and use it on all my future projects or is it too early for me? Do employers favour MVC over WebForms when recruiting junior developers?

• Why use try … finally without a catch clause?

  - by Nick Rosencrantz

  The classical way to program is with try / catch but when is it appropriate to use try without catch? In Python the following appears legal and can make sense: try: #do work finally: #do something unconditional But we didn't catch anything. Similarly one could think in Java it would be try { //for example try to get a database connection } finally { //closeConnection(connection) } It looks good and suddenly I don't have to worry about exception types etc. But if this is good practice, when is it good practice? Or reasons why this is not good practice or not legal (I didn't compile the source I'm asking about and it could be a syntax error for Java but I checked that the Python surely compiles.) A related problem I've run into is that I continue writing the function / method and at the end I must return something and I'm in a place which should not be reached and it must be a return point so even if I handle the exceptions above I'm still returning null or an empty string at some point in the code which should not be reached, often the end of the method / function. I've always managed to restructure to code so that I don't have to return null since that absolutely appears to look like less than good practice.

• Practical Meta Programming System (MPS)

  - by INTPnerd

  This is in regards to Meta Programming System or MPS by JetBrains. Thus far, from my efforts to learn how to use MPS, I have only learned its basic purpose and that it is very complex. Is MPS worth learning? Is there anyone who already effectively uses MPS to create their own languages and editors for those languages and uses these created editors as their primary way of programming? If so, what types of programs have they made with this? What are the advantages and disadvantages of working with MPS? What is the best way to learn MPS?

• Starting off with web dev with php

  - by pavan kumar

  I'm currently working with Java / C++. I'm interested in web development and am planning to shift my stream. I heard that PHP is a good platform to start off and also it does not require that much of knowledge in technologies like JSP / Servlets or frameworks like springs / struts / hibernate. I have basic ideas about HTML and Javascript as well. I have gone through previous posts in SO and found out the relevant resources as well: http://net.tutsplus.com/tutorials/php/the-best-way-to-learn-php/ http://www.webhostingtalk.com/archive/index.php/t-1028265.html http://www.killerphp.com/ http://phpforms.net/tutorial/tutorial.html http://www.php5-tutorial.com/ etc. Now, my question is: I heard of PHP frameworks like CodeIgniter, Zend Frameworkd and Yii. Doesn't learning PHP & MySql implicitly makes us aware of these frameworks? Am I making a good choice in stating with PHP? Is it a good idea to shift streams?

• Block elements vs inline elements in HTML: why the distinction?

  - by EpsilonVector

  The distinction between block and inline elements always seemed strange to me. The whole difference is that a block element takes up the entire width thus forcing a line break before and after the element, and an inline element only takes up as much as the content. Why not just have one type of element- an inline element where you can also apply custom height/width, and use that? You want line breaks? Insert a <br />, or maybe add a special tag in the CSS for that behavior. The way it's now, I don't see it solving any problem, and instead it only forces a property that in my opinion should be decided by a designer. So why the two types?

• What can I do with the twitter API?

  - by aditya menon

  I've tried googling for this but could not find concrete developer examples. When building mundane daily web applications like Classified websites, Job boards or Intranet targeted Document Management Systems, how can the twitter API help me do more things. May I please have some examples on how developers have used twitter to make their apps better? Other than the obvious use for promotional and search engine optimization purpose (yay there's a new job post on our site), what can I do with it? Also, am I late to the party? I hear a lot of upset on the internet about how twitter is apparently slowly betraying developers (I don't understand the specifics), so should I even look at the system or consider alternatives?

• Should I group all of my .js files into one large bundle?

  - by Scottie

  One of the difficulties I'm running into with my current project is that the previous developer spaghetti'd the javascript code in lots of different files. We have modal dialogs that are reused in different places and I find that the same .js file is often loaded twice. My thinking is that I'd like to just load all of the .js files in _Layout.cshtml, and that way I know it's loaded once and only once. Also, the client should only have to download this file once as well. It should be cached and therefore shouldn't really be a performance hit, except for the first page load. I should probably note that I am using ASP.Net bundling as well and loading most of the jQuery/bootstrap/etc from CDN's. Is there anything else that I'm not thinking of that would cause problems here? Should I bundle everything into a single file?
