• How would it be if browsers natively *hosted* JavaScript frameworks? [closed]

  - by João Ramos

  More than 20 million websites nowadays are running jQuery and more than 1/5 of the top million websites are also doing so. What if we, as designers and developers, could take advantage of locally cached JavaScript libraries like jQuery, Prototype, script.aculo.us, etc? Wouldn't it be great if we could provide users with faster websites and experiences? EDIT: My apologies, I ment to ask how hould it be if browsers hosted JavaScript frameworks, not support them. Actually, there's no sense in my previous question. Sorry for that.

• Why should i write a commit message?

  - by acidzombie24

  Why should i write a commit message? I dont want to and i think its stupid every single time. A gui frontend i use which will go unnamed forces you to do it. I hear other doing it everytime even if they are using the VCS on the command line. If i commit several times a day and havent finish a feature what am i writing about? I ONLY ever write a message after many comments and i feel its time for a mini tag or when i do an actual tag. Am i right or am i missing something? also i am using a distributed system

• "My stuff" vs. "Your stuff" in UI texts

  - by John Isaacks

  When refering to a users stuff should you use My or Your, for example: My Cart | My Account | My Wishlist Or Your Cart | Your Account | Your Wishlist I found this article that argues for the use of your. It says flikr does this. It also says MySpace and MyYahoo are wrong. I also noticed today that Amazon uses the term Your. However, I have heard they are the masters at testing variations and finding the best one, so what you see on their site might be the best variation, or simply something they are currently testing. I personally like the way my looks better, but thats just my opinion. What do you think? What will hever the better impact on customers? Does it really even matter?

• complex access control system

  - by Atul Gupta

  I want to build a complex access control system just like Facebook. How should I design my database so that: A user may select which streams to see (via liking a page) and may further select to see all or only important streams. Also he get to see posts of a friend, but if a friend changes visibility he may or may not see it. A user may be an owner or member of a group and accordingly he have access. So for a user there is so many access related information and also for each data point. I use Perl/MySQL/Apache. Any help will be appreciated.

• Does Azure only support ASP.NET MVC applications and if so how should I adapt my design?

  - by RPK

  I am writing a small ASP.NET Web Application. My worries are that I want to keep the architecture same giving me the option to install it on an Intranet or on a Cloud Platform. I am not using MVC but lately learned that Azure only supports ASP.NET MVC applications. I want to know whether ASP.NET Web Forms application work on Azure/AppHarbor or not. Do I need to convert this application to MVC if Web Forms is not supported? Will the same application run on Intranet as well?

• What is meant by Scope of a variable?

  - by Appy

  I think of the scope of a variable as - "The scope of a particular variable is the range within a program's source code in which that variable is recognized by the compiler". That statement is from "Scope and Lifetime of Variables in C++", which I read many months ago. Recently I came across this in LeMoyne-Owen College courses: What exactly is the difference between the scope of variables in C# and (C99, C++, Java) when However a variable still must be declared before it can be used

• How to build MVC Views that work with polymorphic domain model design?

  - by Johann de Swardt

  This is more of a "how would you do it" type of question. The application I'm working on is an ASP.NET MVC4 app using Razor syntax. I've got a nice domain model which has a few polymorphic classes, awesome to work with in the code, but I have a few questions regarding the MVC front-end. Views are easy to build for normal classes, but when it comes to the polymorphic ones I'm stuck on deciding how to implement them. The one (ugly) option is to build a page which handles the base type (eg. IContract) and has a bunch of if statements to check if we passed in a IServiceContract or ISupplyContract instance. Not pretty and very nasty to maintain. The other option is to build a view for each of these IContract child classes, breaking DRY principles completely. Don't like doing this for obvious reasons. Another option (also not great) is to split the view into chunks with partials and build partial views for each of the child types that are loaded into the main view for the base type, then deciding to show or hide the partial in a single if statement in the partial. Also messy. I've also been thinking about building a master page with sections for the fields that only occur in subclasses and to build views for each subclass referencing the master page. This looks like the least problematic solution? It will allow for fairly simple maintenance and it doesn't involve code duplication. What are your thoughts? Am I missing something obvious that will make our lives easier? Suggestions?

• Any good, easy to learn from books or tutorials for learning assembly? [on hold]

  - by pythonian29033

  I've been a developer since 2009 and I've learnt a lot of languages since, but I've always wanted to understand and be able to code in the lowest level language so I can directly (or at least very close to directly) speak to machines through my code. There was a point in time when someone showed me how to do an if statement in assembly, but out of all the books that I got, I could never really understand where/how to start learning to code in assembler. any help please? I'm obsessed with learning this! PS: if you have any software suggestions, I use ubuntu and am looking to convert to backtrack soon, so it would be preferred if you could give me something that'll be easily installed on debian linux, otherwise don't sweat it, give me the name of the windows software and I'll find an equivalent myself

• Do you ever worry that you're more concerned with how something is built rather than what you are actually building?

  - by Rob Stevenson-Leggett

  As a programmer I have an inherent nagging annoyance at my tools, other peoples code, my code, the world in general. I always want to improve it. So I refactor, I stay on top of the latest techniques. I try and learn patterns, I try to use frameworks so as not to reinvent the wheel. I can write a tech spec that will blow your socks off with the amount of patterns I can squeeze in. However, lately I feel I actually know more about the tools I use than how to actually implement successful software. I feel like I'm lacking in the human factors skill set and I believe that to be a successful software engineer takes more than knowing the coolest framework. I think it needs some of the following skillsets too. Interaction design User experience Marketing I've got a bit of this that I've learned from people I've worked with and great projects I've worked on but I don't feel like I "own" these skills. Am I right? Should I be trying to develop these skills further, or should these be left to the people who do these for a career? How do you make sure you don't get too tied up in how you're doing something and make sure you "make your users awesome"? Does anyone know of good resources for learning these skills from a programming point of view?

• May I use full-texted feed for my News Reader app?

  - by Mahdi Ghiasi

  I'm creating a news reader app. (Users will choose sources, but not the exact feed addresses. for example, they can choose Gizmodo but they will not see the exact url of Gizmodo's feed) Some of sources are giving partial feeds, and user must go to their website to read the complete article. My question is, May I make a fulltext version of their feed (for example, using this service) and use it instead of their feed in my News reader categories? Am I legally/ethically allowed to do this? What about using some other service like Readability? (Readability gives HTML page instead of feed as input, but anyway, output will be clean article without any advertises or such) Please note that some of these partial feeds may have some advertises inside, but the fulltext feed generators usually remove that advertises.

• What should be the minimal design/scope documentation before development begins?

  - by Oliver Hyde

  I am a junior developer working on my own in the programming aspect of projects. I am given a png file with 5-6 of the pages designed, most times in specific detail. From this I'm asked to develop the back end system needed to maintain the website, usually a cataloging system with products, tags and categories and match the front end to the design. I find myself in a pickle because when I make decisions based on assumptions about the flow of the website, due to a lack of outlining details, I get corrected and am required to rewrite the code to suit what was actually desired. This process happens multiple times throughout a project, often times on the same detail, until it's finally finished, with broken windows all through it. I understand that projects have scope creep, and can appreciate that I need to plan for this, but I feel that in this situation, I'm not receiving enough outlining details to effectively plan for the project, resulting in broken code and a stressed mind. What should be the minimal design/scope documentation I receive before I begin development?

• Scientific evidence that supports using long variable names instead of abbreviations?

  - by Sebastian Dietz

  Is there any scientific evidence that the human brain can read and understand fully written variable names better/faster than abbreviated ones? Like PersistenceManager persistenceManager; in contrast to PersistenceManager pm; I have the impression that I get a better grasp of code that does not use abbreviations, even if the abbreviations would have been commonly used throughout the codebase. Can this individual feeling be backed up by any studies?

• How do developers verify that software requirement changes in one system do not violate a requirement of downstream software systems?

  - by Peter Smith

  In my work, I do requirements gathering, analysis and design of business solutions in addition to coding. There are multiple software systems and packages, and developers are expected to work on any of them, instead of being assigned to make changes to only 1 system or just a few systems. How developers ensure they have captured all of the necessary requirements and resolved any conflicting requirements? An example of this type of scenario: Bob the developer is asked to modify the problem ticket system for a hypothetical utility repair business. They contract with a local utility company to provide this service. The old system provides a mechanism for an external customer to create a ticket indicating a problem with utility service at a particular address. There is a scheduling system and an invoicing system that is dependent on this data. Bob's new project is to modify the ticket placement system to allow for multiple addresses to entered by a landlord or other end customer with multiple properties. The invoicing system bills per ticket, but should be modified to bill per address. What practices would help Bob discover that the invoicing system needs to be changed as well? How might Bob discover what other systems in his company might need to be changed in order to support the new changes\business model? Let's say there is a documented specification for each system involved, but there are many systems and Bob is not familiar with all of them. End of example. We're often in this scenario, and we do have design reviews but management places ultimate responsibility for any defects (business process or software process) on the developer who is doing the design and the work. Some organizations seem to be better at this than others. How do they manage to detect and solve conflicting or incomplete requirements across software systems? We currently have a lot of tribal knowledge and just a few developers who understand the entire business and software chain. This seems highly ineffective and leads to problems at the requirements level.

• Making a C# w/ WPF multiple frame text / pseudo-calendar GUI application [closed]

  - by Gregor Samsa

  I am editing a recently asked question and making it specific, taking the advice of some people here. I would like to program of the following simple form: The user can produce X number of resizable frames (analogous to HTML frames). Each frame serves as a simple text editor, which you can type into and save the whole configuration including resized windows and text. The user should be able alternately "freeze" and present the information, and "unfreeze" and edit frames. I want to use C## with WPF, in Microsoft's Visual C#. I do not yet know this language. I am sure I can pick up the syntax, but I would like to ask about some general advice for how to structure such a program. I have never made a GUI program, let alone one that interfaces with a notepad or some basic text editor. Can someone either direct me to a good resource that will teach me how to do the above? Or outline the basic ingredients that such a program will require, keeping in mind that though I know some C and Python, I have no experience with GUIs or advanced programming generally? In particular I don't know how to incorporate this "text editor" aspect of the program, as well as the resizable frames I would greatly appreciate any help.

• What is the best practice for when to check if something needs to be done?

  - by changokun

  Let's say I have a function that does x. I pass it a variable, and if the variable is not null, it does some action. And I have an array of variables and I'm going to run this function on each one. Inside the function, it seems like a good practice is to check if the argument is null before proceeding. A null argument is not an error, it just causes an early return. I could loop through the array and pass each value to the function, and the function will work great. Is there any value to checking if the var is null and only calling the function if it is not null during the loop? This doubles up on the checking for null, but: Is there any gained value? Is there any gain on not calling a function? Any readability gain on the loop in the parent code? For the sake of my question, let's assume that checking for null will always be the case. I can see how checking for some object property might change over time, which makes the first check a bad idea. Pseudo code example: for(thing in array) { x(thing) } Versus: for(thing in array) { if(thing not null) x(thing) } If there are language-specific concerns, I'm a web developer working in PHP and JavaScript.

• The value of an updated specification

  - by Mr. Jefferson

  I'm at the tail end of a large project (around 5 months of my time, 60,000 lines of code) on which I was the only developer. The specification documents for the project were designed well early on, but as always happens during development, some things have changed. For example: Bugs were discovered and fixed in ways that don't correspond well with the spec Additional needs were discovered and dealt with We found areas where the spec hadn't thought far enough ahead and had to change some implementation Etc. Through all this, the spec was not kept updated, because we were lean on resources (I know that's a questionable excuse). I'm hoping to get the spec updated soon when we have time, but it's a matter of convincing management to spend the effort. I believe it's a good idea, but I need some good reasoning; I can't speak from very much experience because I'm only a year and a half out of school. So here are my questions: What value is there in keeping an updated spec? How often should the spec be updated? With every change made that might affect it, just at the end of development, or something in between? EDIT to clarify: this project was internal, so no external client was involved. It's our product.

• What is the difference between WCF service and a simple Web service in developing using .NET Framework?

  - by Steve Johnson

  My questions are: What is the difference between WCF service and a simple Web service in .NET Framework? What a WCF Service can do which a .NET Web service cant? In other words, what are the limitation of .NET Web services which were overcome in WCF services? I understand that WCF are REST based and .NET web services are SOAP based. But I need to know more than that. How a developer will make a design decision whether to developer a Web service or a WCF service?

• .NET Properties - Use Private Set or ReadOnly Property?

  - by tgxiii

  In what situation should I use a Private Set on a property versus making it a ReadOnly property? Take into consideration the two very simplistic examples below. First example: Public Class Person Private _name As String Public Property Name As String Get Return _name End Get Private Set(ByVal value As String) _name = value End Set End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo Me.Name = txtInfo.ToTitleCase(Me.Name) End Sub End Class // ---------- public class Person { private string _name; public string Name { get { return _name; } private set { _name = value; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; this.Name = txtInfo.ToTitleCase(this.Name); } } Second example: Public Class AnotherPerson Private _name As String Public ReadOnly Property Name As String Get Return _name End Get End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo _name = txtInfo.ToTitleCase(_name) End Sub End Class // --------------- public class AnotherPerson { private string _name; public string Name { get { return _name; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; _name = txtInfo.ToTitleCase(_name); } } They both yield the same results. Is this a situation where there's no right and wrong, and it's just a matter of preference?

• Scrum: How to work on one story at a time

  - by Juergen

  I was nominated as scrum master in a new formed scrum team. We have already done some sprints. In the beginning I tried to make my team to work on one story at a time. But it didn't work. My team had difficulties to distribute the tasks in a way that they can work simultaneously on one story. Maybe we are doing something wrong? For example: we have a story to create a new dialog. We create the following tasks: Create Model classes Read model data from database Connect model classes with view Implement dialog handling Save data on close Test Documentation Solution Description Can theses tasks be done by more than one person at a time? The tasks - more or less - build upon each other. Or do we design the tasks in a wrong way?

• How can we distribute a client app to other non-US businesses?

  - by Simon

  I'm working on an app which acts as a client for our web service. We sell this service to businesses, and we want to distribute the app to their employees for free. The app will be customised for each client. If we were in the US, my understanding is that we'd ask them to enrol in the volume purchasing program, and submit a version of our app for each business, for enterprise distribution at the free price point However, the businesses aren't all in the US, so they can't enrol in the VPP. They have thousands of employees, so promo codes won't be sufficient. What are our alternatives?

• Rewrote GNU GPL v2 code in another language: can I change a license?

  - by Anton Gogolev

  I rewrote some parts of Mercurial (which is licensed under GNU GPL v2) in C#. Naturally, I looked a lot into original Python code and some parts are direct translations from Python to C#. Is is possible have "my code" licensed under different terms or to even make a part of a closed-source commercial application? If not, can I re-license "my-code" under LGPL, open-source it and then use this open-sourced C# library in my closed-source commercial application?

• How do programmer-seeking employers see Bioinformatics degree?

  - by Max

  I love programming, but I also love biology. Basically Bioinformatics sounds fun to me. However, there is a fat chance that I won't get a Bioinformatics job and will be forced to build my career around regular programming. Therefore a question: does it matter (much) for an employer if he is looking for a regular programmer but finds a Bioinformatics diploma? Or is it the same in the long run as a regular Informatics diploma?

• .NET developer needs FoxPro advice

  - by katit

  We have a prospect with FoxPro 2.6 (whatever it means) system. Our product integrates with other systems by the means of triggers (usually). We would place couple of triggers on X system and then just pull collected data for our use. This way there is no need to customize customers product and it works great(almost real time - we poll for changes every 30 seconds). Question: Can I put triggers on FoxPro 2.6? Can access FoxPro from .NET? Any catches/caveats?

• Python C API return more than one value / object without building a tuple [migrated]

  - by Grisu

  I got the following problem. I have written a C-Extension to Python(2.7 / 3.2) to interface a self written software library. Unfortunately I need to return two values from the function where the last one is optional. In Python I tried def func(x,y): return x+y, x-y test = func(13,4) but test is a tuple. If I write test1,test2 = func(13,4) I got both values separated. Is there a possibility to return only one value without unpacking the tuple, i.e. the second(,.. third, ..fourth) value gets neglected? And if such a solution existst, how does it look for the C-API? Because return Py_BuildValue("ii",x+y,x-y); results in a tuple as well.

• Is there a snippets program that allows for tab entry of variables across the mac?

  - by Jeremy Smith

  I love Sublime Text editor and the ability to create code snippets like so: <snippet> <content><![CDATA[\$("${1:selector}").${2:method}]]></content> <tabTrigger>jq</tabTrigger> </snippet> This allows me to type jq[tab] and then have it expand to $("selector").method where I am able to tab through the string 'selector' and 'method' in order to change them. But what I'd really like to do is use this same snippet when working in Chrome Dev Tools, so I was looking for a mac snippets program that could support this. However, the three programs that I looked at (Keyboard Maestro, Snippets, CodeBox) don't support the ability to tab through to highlight predetermined strings and change them. Does anyone know of an app that will do this?
