• What development terms come from the construction industry?

  - by Renesis

  When talking with colleagues about software design and development principles, I've noticed one of the most common sources for analogies is the construction industry. It would be quite useful to have a list of what programming/development terms and concepts are borrowed from construction industry? (And please provide a description or experiences regarding that topic.) [Credit to Programming concepts taken from the arts and humanities for the idea]

• Professional iOS Development as a Backup Career [closed]

  - by New Coder

  I am a research chemist by day and I am a self-taught hobbyist iOS programmer by night. I am in the process of developing a moderately complex iOS app and hope to launch it within a month or two. I love everything about iOS development (and programming in general). I want to know if iOS development could become a backup career for me if I loose my job. My question: Let's say I had a couple of apps in the app store, a solid foundation in objective-C and the apple frameworks and basic knowledge on network integrated apps. Without a formal CS degree, what other experience/knowledge would I need to land a job as a professional iOS developer? Forgive me if this question is out of bounds for this forum. If it is, suggestions on where to post such a question would be appreciated.

• Implementing a "state-machine" logic for methods required by an object in C++

  - by user827992

  What I have: 1 hypothetical object/class + other classes and related methods that gives me functionality. What I want: linking this object to 0 to N methods in realtime on request when an event is triggered Each event is related to a single method or a class, so a single event does not necessarily mean "connect this 1 method only" but can also mean "connect all the methods from that class or a group of methods" Avoiding linked lists because I have to browse the entire list to know what methods are linked, because this does not ensure me that the linked methods are kept in a particular order (let's say an alphabetic order by their names or classes), and also because this involve a massive amount of pointers usage. Example: I have an object Employee Jon, Jon acquires knowledge and forgets things pretty easily, so his skills may vary during a period of time, I'm responsible for what Jon can add or remove from his CV, how can I implement this logic?

• How to implement Facebook leaderboard game for mobile?

  - by TrueGrime

  I am in the final stages of developing an indie C# mobile game that I will deploy to iPhones and Androids using Mono. I wish to add push notifications and a Facebook leader board feature into the game, such that the user will be presented with a list of all his/her friends that are playing the game and their weekly scores in the main screen. I have ZERO experience with web development/networking/databases. I recently started researching the field and formed a basic understanding. Facebook has SDKs in PHP, JavaScript, obj-c and java, tho reading the documentation examples still feels cryptic to me since it involves web/server tech. After researching some more, I understood that my options for server side are basically PHP or ASP.Net. It seems that ASP.Net is more favorable in my case since I am already proficient with C# (but there is no ASP.net SDK from Facebook... I am not sure if this implies that I cant interact with Facebook using ASP.Net). On the down side some have mentioned higher costs for ASP.Net, tho I havent looked further into that aspect yet. I also understood that JavaScript is client side technology. I started going through tutorials of ASP.Net, I was thinking that ASP.Net is a purely server side management language, but it started feeling more like WPF as those tutorials started getting into very lengthy discussions about creating website interfaces and styles. I am not interested in that, I just want to have a web server which my app can somehow communicate with and get friends/scores. Am I learning the right technologies for my goal? should I be learning something else? I am posting this in hopes that someone who knows this field well can see through my problem and help guide me, otherwise I could spend months studying something that might not be the right solution to my goal. Thanks.

• How to write a user story specific to tasks in this case

  - by vignesh

  We have planned to take up an user story say As a player I want to view the game map to know current standings of my team The sprint is for two weeks. We will be able to complete only HTML in two weeks time, this user story will take 4-6 weeks to be completed as we have a shortage of content designing resources. How can we change this user story so that HTML completion can be considered as a done for this user story and we need to take up the integration of this user story in the next sprint? Is it possible to create two different user stories, one for HTML and other for integration, testing, bug fixing etc?

• Visual web page designer for Django?

  - by Robert Oschler

  I'm just starting my Django learning so pardon me if any part of this question is off-base. I have done a lot of web searching for information on the equivalent of a visual web page designer for Django and I don't seem to be getting very far. I have experience with Delphi (Object Pascal), C, C++, Python, PHP, Java, and Javascript and have created and maintained several web sites that included MySQL database dependent content. For the longest time I've been using one of the standard WYSIWIG designers to design the actual web pages, with any needed back end programming done via Forms or AJAX calls that call server side PHP scripts. I have grown tired of the quirks, bugs, and other annoyances associated with the program. Also, I find myself hungry for the functionality and reliability a good MVC based framework would provide me so I could really express myself with custom code easily. So I am turning to Django/Python. However, I'm still a junkie for a good WYSIWIG designer for the layout of web pages. I know there are some out there that thrive on opening up a text editor, possibly with some code editor tools to assist, and pounding out pages. But I do adore a drag and drop editor for simple page layout, especially for things like embedded images, tables, buttons, etc. I found a few open source projects on GitHub but they seem to be focused on HTML web forms, not a generic web page editor. So can I get what I want here? The supreme goal would be to find not only a web page editor that creates Django compatible web pages, but if I dare say it, have a design editor that could add Python code stubs to various page elements in the style of the Delph/VCL or VB design editors. Note, I also have the Wing IDE Professional IDE, version 2.0. As a side note, if you know of any really cool, fun, or time-saving Python libraries that are designed for easy integration into Django please tell me about them. -- roschler

• Open Source Security packages for Rails

  - by Edwin

  I'm currently creating a complete web application using Rails 3 to familiarize myself with its inner workings and to gain a better appreciation of a working web application's moving parts. (Plus, since I'm still working on my degree, I hope that it will give me a better idea of what's BS in my education requirements and which weaknesses/skills I should focus on.) The example application I'm working on is an ecommerce site, and I've already configured the backend, routes, controllers, and so on. As part of the application, I'd like to integrate a second layer of security on top of the one Rails already provides for user authentication. However, I've been unable to find any on Google, with the exception of OAuth - which, from my understanding, is meant to secure API calls. While I could roll my own secure authentication system, I'm only in my second year of college and recognize that A) I know little about security, and B) there are developers that know much more about security that are working on open-source projects. What are some actively developed open-source security packages or frameworks that can be easily added to Rails? Pros and cons are not necessary, as I can do the research myself. P.S. I'm not sure whether I posted this in the right SE site; please migrate to SO or Security if it is more appropriate there.

• Choosing a web development framework?

  - by Bob

  So, I've sort of reached a point where I want to start developing a website. Originally, I planned to build said website using PHP and CodeIgniter, I'm familiar with both, but, truth be told, I'm not too fond of either. I find they just get rather messy, CodeIgniter helps somewhat, but no matter what, it seems that most PHP comes out more obfuscated than it has to be. Anyways, I've come to the point where I want to either use Python or Ruby. I'm familiar in both, though more so towards Python, but I've never done any web development in them. I'll take the necessary time to learn the frameworks (and further my knowledge in the language of my choosing), but I need to choose one. I don't like either language more than the other, they both have their benefits... However, since I've never done any web development with either language, I was hoping that you guys could give me some pointers. What are the available frameworks for each language? What do you recommend and why? Note: I've primarily looked into Rails and Django - but I'm still open to others. I'm looking for one that will work for just one (or maybe two) developers. It has to be fairly easy to learn (but I will take the time to learn it). Also, I'd like it to easily support clean code and agile development.

• Complexity of a web application

  - by Dominik G

  I am currently writing my Master's Thesis on maintainability of a web application. I found some methods like the "Maintainability Index" by Coleman et.al. or the "Software Maintainability Index" by Muthanna et.al. For both of them one needs to calculate the cyclomatic complexity. So my question is: Is it possible to measure the cyclomatic complexity of a web application? In my opinion there are three parts to a web application: Server code (PHP, C#, Python, Perl, etc.) Client code (JavaScript) HTML (links and forms as operators, GET-parameters and form fields as operands!?) What do you think? Is there another point of view on the complexity of web application? Did I miss something?

• Why is TDD not working here?

  - by TobiMcNamobi

  I want to write a class A that has a method calculate(<params>). That method should calculate a value using database data. So I wrote a class Test_A for unit testing (TDD). The database access is done using another class which I have mocked with a class, let's call it Accessor_Mockup. Now, the TDD cycle requires me to add a test that fails and make the simplest changes to A so that the test passes. So I add data to Accessor_Mockup and call A.calculate with appropriate parameters. But why should A use the accessor class at all? It would be simpler (!) if the class just "knows" the values it could retrieve from the database. For every test I write I could introduce such a new value (or an if-branch or whatever). But wait ... TDD is more. There is the refactoring part. But that sounds to me like "OK, I can do this all with a big if-elseif construct. I could refactor it using a new class ... but instead I make use of the DB accessor and do this in a totally different way. The code will not necessarily look better afterwards but I know I WANT to use the database".

• Is data integrity possible without normalization?

  - by shuniar

  I am working on an application that requires the storage of location information such as city, state, zip code, latitude, and longitude. I would like to ensure: Location data is accurate Detroit, CA Detroit IS NOT in California Detroit, MI Detroit IS in Michigan Cities and states are spelled correctly California not Calefornia Detroit not Detriot Cities and states are named consistently Valid: CA Detroit Invalid: Cali california DET d-town The D Also, since city/zip data is not guaranteed to be static, updating this data in a normalized fashion could be difficult, whereas it could be implemented as a de facto location if it is denormalized. A couple thoughts that come to mind: A collection of reference tables that store a list of all states and the most common cities and zip codes that can grow over time. It would search the database for an exact or similar match and recommend corrections. Use some sort of service to validate the location data before it is stored in the database. Is it possible to fulfill these requirements without normalization, and if so, should I denormalize this data?

• How do you use blank lines in your code ?

  - by Matthieu M.

  There has been a few remarks about white space already in discussion about curly braces placements. I myself tend to sprinkle my code with blank lines in an attempt to segregate things that go together in "logical" groups and hopefully make it easier for the next person to come by to read the code I just produced. In fact, I would say I structure my code like I write: I make paragraphs, no longer than a few lines (definitely shorter than 10), and try to make each paragraph self-contained. For example: in a class, I will group methods that go together, while separating them by a blank line from the next group. if I need to write a comment I'll usually put a blank line before the comment in a method, I make one paragraph per step of the process All in all, I rarely have more than 4/5 lines clustered together, meaning a very sparse code. I don't consider all this white space a waste because I actually use it to structure the code (as I use the indentation in fact), and therefore I feel it worth the screen estate it takes. For example: for (int i = 0; i < 10; ++i) { if (i % 3 == 0) continue; array[i] += 2; } I consider than the two statements have clear distinct purposes and thus deserve to be separated to make it obvious. So, how do you actually use (or not) blank lines in code ?

• As a C# developer, would you learn Java to develop for Android or use MonoDroid instead?

  - by Dan Tao

  I'd consider myself pretty well versed in C#. It's my language of choice at the moment, and it's where basically all my professional experience lies. Still, I'm puzzled by the existence of the MonoDroid project. My understanding has always been that C# and Java are very close. Like, if you know one, you can learn the other really quickly. So, as I've considered developing my first Android app, I just assumed I would familiarize myself with Java enough to get started and then just sort of learn as I go. Wouldn't this make more sense than using MonoDroid, which is likely to be less feature-rich than the Java Android SDK, and requires learning its own API (albeit a .NET API) anyway? I just feel like it would be better to learn a new language (and an extremely popular one at that) and get some experience in it—when it's so close to what you already know anyway—rather than stick with a technology you're experienced with, without gaining any more valuable skills. Maybe I'm grossly misrepresenting the average potential MonoDroid user. Maybe it's more for people who are experienced in Java and .NET and just prefer .NET. Or maybe (in fact it's likely) there are other factors I just haven't considered. I'm just wondering, why would you use MonoDroid instead of just developing for Android using Java?

• What can Haskell's type system do that Java's can't and vice versa?

  - by Matt Fenwick

  I was talking to a friend about the differences between the type systems of Haskell and Java. He asked me what Haskell's could do that Java's couldn't, and I realized that I didn't know. After thinking for a while, I came up with a very short list of minor differences. Not being heavy into type theory, I'm left wondering whether they're formally equivalent. To try and keep this from becoming a subjective question, I'm asking: what are the major, non-syntactical differences between their type systems? I realize some things are easier/harder in one than in the other, and I'm not interested in talking about those. And to make it more specific, let's ignore Haskell type extensions since there's so many out there that do all kinds of crazy/cool stuff.

• Is it possible for beginner to learn and develop an application in rails in 4 months?

  - by Parth

  I want to develop a web application or a website using rails. My current knowledge includes 1. HTML 2. CSS 3. C 4. Java And I am currently going through 5th chapter of the well grounded rubyist book by David A. Thomas. I came to know that learning ruby is beneficial for good knowledge of rails. So currently I am going through the basics of ruby. And learning rails in parallel. I want to know if in this scenario is it practically feasible to understand rails and develop an application/website in it within the time frame of 4 months. I need to develop an application which have atleast 3 complexity (complex functionality). Any ideas of good application for rails beginners is welcomed. But the application should be large or if it is small than it should have some complexity. Time is a constraint for me. I would have to develop application for college work but rails technology is my choice as I want to learn it.

• Dynamic Forms: Pattern or AntiPattern?

  - by Segfault

  I'm sure you've seen it. The database has a bunch of tables called Forms, Controls,FormsControls, ControlSets, Actions and the program that queries these tables has a dynamically generated user interface. It will read all the forms, load a home page that has links to them all, or embed them in some tabbed or paged home page, and for each of those forms it will read the various text boxes, check boxes, radio buttons, submit buttons, combo boxes, labels and whatnot from the controls and form-to-control join tables, lay those elements out according to the database and link all the controls to logic according to other rules in the database. To me, this is an anti-pattern. It actually make the application more difficult to maintain because the design of it is now spread out into multiple different systems. Also, the database is not source controlled. Sure, it may make one or two changes go more quickly, after you've analyzed the program anyway to understand how to change the data and as long as you don't stray from the sort of changes that were anticipated and accounted for, but that's often just not sustainable. What say you?

• Has anyone used these database publish tools in Visual Studio 2012/2013 ?

  - by punkouter

  I am trying to figure out if they are actually useful... I have a DBProject and it would be nice if when I publish from my DEV to my TEST it what automatically copy the schema and data from DEV to TEST.. is that what this tab in visual studio is for ? On PROD I would never want to copy the data over but maybe I would change the schema and want to move that schema to PROD.. so is that what this tab is for ? For now we are using WEB DEPLOY but none of these database options.. We are manually using DATA COMPARE to sync changes on the various databases/DBproject... Any advice?

• Formalizing a requirements spec written in narrative English

  - 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.

• Can I trust the Basic schedule equation?

  - by Steve Campbell

  I've been reading Steve McConnell's demystifying the black art of estimating book, and he gives an equation for estimating nominal schedule based on Person-months of effort: ScheduleInMonths = 3.0 x EffortInMonths ^ (1/3) Per the book, this is very accurate (within 25%), although the 3.0 factor above varies depending on your organization (typically between 2 and 4). It is supposedly easy to use historical projects in your organization to derive an appropriate factor for your use. I am trying to reconcile the equation against Agile methods, using 2-6 week cycles which are often mini-projects that have a working deliverable at the end. If I have a team of 5 developers over 4 weeks (1 month), then EffortInMonths = 5 Person Months. The algorithm then outputs a schedule of 3.0 x 5^(1/3) = 5 months. 5 months is much more than 25% different than 1 month. If I lower the 3.0 factor to 0.6, then the algorthim works (outputs a schedule of approx 1 month). The lowest possible factor mentioned in the book through is 2.0. Whats going on here? I want to trust this equation for estimating a "traditional" non-agile project, but I cannot trust it when it does not reconcile with my (agile) experience. Can someone help me understand?

• Is running "milli"-benchmarks a good idea?

  - by Konstantin Weitz

  I just came across the Caliper project and it looks very nice. Reading the introduction to microbenchmarks, one gets the feeling that the developers would not suggest to use the framework if the benchmark takes longer than a second or so. I looked at the code and it looks like a RuntimeOutOfRangeException is actually thrown if a scenario takes longer than 10s to execute. Could you explain to me what the problems are with running larger benchmarks? My motivation for using Caliper was to compare two join-algorithm implementations. Those will definitely run for quite some time and will do some disk IO, yet running the entire database would make it hard to do the comparison, because the configuration of the algorithms and the visualization of the results would be a pain.

• Does professionalism in job postings matter?

  - by Wings87

  I came across this job posting: http://www.justin.tv/jobs/jobs. The page contains some bad language ("No bulls--t"). I personally find this vaguely offensive, and it would certainly put me off applying to work there: It made me wonder what kind/personality of people work at this company. At least where I'm from (EU), the language would be considered bad form, and it would be seen as badly representing the company. Some job postings seem to go to the other extreme, filled with vacuous people skill descriptions and irrelevant details. It's tempting to dream up pictures of each company based on their job posting. So, does professionalism in job postings matter? Are you inclined to see through bad language, irrelevant corporate speak and so on, or do these affect interest in a job?

• What do you think about starting a reading group?

  - by Imran Omar Bukhsh

  Greetings everyone I know we as software engineers / developers always need to keep learning. I really wanted to start a reading group where people can be reading books and discussing about whatever they read like at the end of every chapter when everyone has finished by a particular time. We could also have like a min. limit of n pages per day for every person that participates in the group. What do you think? Do advise.

• Should I avoid SharePoint Development in Visual Studio?

  - by SaphuA

  Hello, Not long ago I started an internship at a company that supplies SharePoint consultancy, hosting and development. While their consultancy seems to be pretty good and solid, I feel their development department lacks direction. The reason for this, most likely, is that they stopped outsourcing not too long ago. One thing that I've frequently bumped my head into is the following: My supervisor strongly insists that everything that can be done natively in SharePoint (somehow this includes editing xslt files in Designer) should be done in SharePoint. Even if this results in longer development time (at least when they make me write XSLT) and reduced usability. Her main arguments for this are: Better maintainability Editing the functionality doesn't require programming knowledge I feel the company is a little biassed and I am unable to get a decent discussion going. This is why I am looking for other places to get some responses on the subject (and not only on the arguments of my supervisor, but more on the subject in general). Kind regards

• Multi MVC processing vs Single MVC process

  - by lordg

  I've worked fairly extensively with the MVC framework cakephp, however I'm finding that I would rather have my pages driven by the multiple MVC than by just one MVC. My reason is primarily to maintain an a more DRY principle. In CakePHP MVC: you call a URL which calls a single MVC, which then calls the layout. What I want is: you call a URL, it processes a layout, which then calls multiple MVC's per component/block of html on the page. When you compare JavaScript components, AJAX, and server side HTML rendering, it seems the most consistent method for building pages is through blocks of components or HTML views. That way, the view block could be situated either on the server or the client. This is technically my ONLY disagreement with the MVC model. Outside of this, IMHO MVC rocks! My question is: What other RAD frameworks follow the same principles as MVC but are driven rather by the View side of MVC? I've looked at Django and Ruby on Rails, yet they seems to be more Controller driven. Lift/Scala appears to be somewhat of a good fit, but i'm interested to see what others exist.
