• What is the problem git submodules are supposed to solve?

  - by Joshua Dance

  What is the problem that git submodules solve well? When should I use them? Or rather what is their use case? The only use of submodules that I have seen 'in the wild' has been when used to share code between multiple repositories. From what I have experienced, submodules do not appear to be ideally suited to this use case. You run into git update submodule woes and your history gets filled with updating submodule pointer commits. If the 'sharing code' use case is not best solved by submodules, what problems are?

• Transferring at a large software company: ask boss before or after?

  - by ZNZ

  Out of college I joined a large, well-known software company's consulting arm. I've gained lots of experience with some of the company's products but would like to start doing more development work rather than implementation work (traveling less would be nice, too!). The company has some product development positions that I think I could be a good fit for, but I'm unsure of how to bring it up with my manager. After a bit Googling, there are many conflicted answers on how best to handle transferring departments. When should I tell my current manager that I am interested in pursuing other positions in the company? Before or after applying?

• What kind of specific projects can I do to master bitwise operations in C++? Also is there a canonical book? [closed]

  - by Ford

  I don't use C++ or bitwise operations at my current job but I'm thinking of applying to companies where it is a requirement to be fluent with them (on their tests anyway). So my question is: Can anyone suggest a project which will require gaining a fluency in bitwise operations to complete? On a side note, is there a canonical book on optimization techniques using bitwise operations since that seems to be an important use of them?

• How to become an expert web-developer?

  - by John Smith

  I am currently a Junior PHP developer and I really LOVE it, I love internet from first time I got into it, I always loved smartly-created websites, always was wondering how it all works, always admired websites with good design and rich functionality, and finally I am creating web-sites on my own and it feels really great. My goals are to become expert web-developer (aiming for creating websites for small and medium business, not enterprise-sized systems), to have a great full-time job, to do freelance and to create my own startup in future. General question: What do I do to be an expert, professional and demanded web-programmer? More concrete questions: 1). How do I choose languages and technologies needed? I know that every web-developer must know HTML+CSS+JS+AJAX+JQuery, I am doing some design aswell cause I like it and I need it for freelance also. But what about backend languages? Currently I picked PHP cause it's most demanded in my area and most of web uses it, but what would happen in future? Say, in 3 years, I am good at PHP and PHP frameworks by than, but what if some other languages get most popular? Do I switch to them? I know that good programmer is not about languages and frameworks but about ability to learn and to aim the goals, but still I think that learning frameworks for some language can take quite some time. Am I wrong? 2). In general, what are basic guidelines to be expert web-developer? What are most important things I should focus on? Thank you!

• REST or Non-REST on Internal Services

  - by tyndall

  I'm curious if others have chosen to implement some services internally at their companies as non-REST (SOAP, Thrift, Proto Buffers, etc...) as a way to auto-generate client libraries/wrappers? I'm on a two year project. I will be writing maybe 40 services over that period with my team. 10% of those services definitely make sense as REST services, but the other 90% feel more like they could be done in REST or RPC style. Of these 90%, 100% will be .NET talking to .NET. When I think about all the effort to have my devs develop client "wrappers" for REST services I cringe. WADL or RSDL don't seem to have enough mindshare. Thoughts? Any good discussions of this "internal service" issue online? If you have struggled with this what general rules for determining REST or non-REST have you used?

• How to host customer developed code server side

  - by user963263

  I'm developing a multi-tenant web application, most likely using ASP.NET MVC5 and Web API. I have used business applications in the past where it was possible to upload custom DLL's or paste in custom code to a GUI to have custom functions run server side. These applications were self hosted and single-tenant though so the customer developed bits didn't impact other clients. I want to host the multi-tenant web application myself and allow customers to upload custom code that will run server side. This could be for things like custom web services that client side JavaScript could interact with, or it could be for automation steps that they want triggered server side asynchronously when a user takes a particular action. Additionally, I want to expose an API that allows customers' code to interact with data specific to the web application itself. Client code may need to be "wrapped" so that it has access to appropriate references - to our custom API and maybe to a white list of approved libraries. There are several issues to consider - security, performance (infinite loops, otherwise poorly written code, load balancing, etc.), receive compiled DLL's or require raw code, etc. Is there an established pattern for this sort of thing or a sample project anyone can point to? Or any general recommendations?

• 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!

• Best practice with branching source code and application lifecycle

  - by Toni Frankola

  We are a small ISV shop and we usually ship a new version of our products every month. We use Subversion as our code repository and Visual Studio 2010 as our IDE. I am aware a lot of people are advocating Mercurial and other distributed source control systems but at this point I do not see how we could benefit from these, but I might be wrong. Our main problem is how to keep branches and main trunk in sync. Here is how we do things today: Release new version (automatically create a tag in Subversion) Continue working on the main trunk that will be released next month And the cycle repeats every month and works perfectly. The problem arises when an urgent service release needs to be released. We cannot release it from the main trunk (2) as it is under heavy development and it is not stable enough to be released urgently. In such case we do the following: Create a branch from the tag we created in step (1) Bug fix Test and release Push the change back to main trunk (if applicable) Our biggest problem is merging these two (branch with main). In most cases we cannot rely on automatic merging because e.g.: a lot of changes has been made to main trunk merging complex files (like Visual Studio XML files etc.) does not work very well another developer / team made changes you do not understand and you cannot just merge it So what you think is the best practice to keep these two different versions (branch and main) in sync. What do you do?

• What should we tell our unsupported IE6 users?

  - by Dan Fabulich

  In the upcoming version of our web app, we've broken IE6, and we don't intend to fix it. We've had a clear warning posted for IE6 users for some months; we've decided it's time not to support it. My question is: how should we communicate this to our users? Some people here feel that we should block IE6 users who would try to access the web app, because it's not going to work for them. Others feel that we should just leave up a warning, saying "This doesn't work in IE6," but not block them; instead, if they click to dismiss the warning, just let them in to the broken site to see for themselves that it doesn't work. Who is right? Is there a better way?

• What's the best approach to Facebook integration?

  - by Jay Stevens

  I have a new site/app going live next week (or somewhere close). I know there will be a relatively small (15,000?) very dedicated group of people on Facebook who will be very likely to be interested in the site, so I know I need Facebook integration of some kind. I won't be doing Facebook logins or pulling/posting to profiles yet, but I plan to... The question: Do I just do a Facebook "Page" for now? This is faster/easier to set up and seems a little less buggy.. and then migrate to a Facebook App later? or Do I create a "Facebook App" (with the api key/id/secret, etc.) now even if I'm doing nothing but using the "like" button. This means I don't have any migration later and I can use the javascript api to log "like" button clicks to Google Analytics, etc. Thoughts? Experiences? Is there a migration process to move your old Page users to your new "App"? What's the advantages / disadvantages of each.

• Is there a pattern or best practice for passing a reference type to multiple classes vs a static class?

  - by Dave

  My .NET application creates HTML files, and as such, the structure looks like variable myData BuildHomePage() variable graph = new BuildGraphPage(myData) variable table = BuildTablePage(myData) BuildGraphPage and BuildTablePage both require access data, the myData object. In the above example, I've passed the myData object to 2 constructors. This is what I'm doing now, in my current project. The myData object, and it's properties are all readonly. The problem is, the number of pages which will require this object has grown. In the real project, there are currently 4, but the new spec is to have about 20. Passing this object to the constructor of each new object and assigning it to a field is a little time consuming, but not a hardship! This poses the question whether it's better practice to continue as I have, or to refactor and create a new static class for myData which can be referenced from any where in my project. I guess my abilities to use Google are poor, because I did try and find an appropriate pattern as I am sure this type of design must be common place but my results returned nothing. Is there a pattern which is suited, or do best practices lean towards one implementation over another.

• Security issue about making my code public in GitHub

  - by John Doe

  I'm developing a big community/forum website and I'd like to upload my code to GitHub to have at least some sort of version control over it (because I have nothing other than a .rar file as a backup, not even SVN), to let others contribute to the project, and also perhaps using it to let my potential future employers see some of my code as some sort of curriculum. But what I'm wondering now, and I'm suprised I haven't seen anyone mention it before is the security aspect of it. Isn't publishing the code of a website a HUGE security hole? Is like giving a potential hacker or anyone who would like to find any potential exploit possible, even considering that the critical files aren't uploaded (database passwords, authentication scripts, etc.). Of course that there are millions of projects uploaded to GitHub and no one will find mine just 'by chance'. But if they look for it, it would indeed be there. Bottomline: my problem is not about copyright or licenses, but others finding exploits in my website. I'm I missing something here?

• What would you do to improve the working of a small Development team?

  - by Omar Kooheji

  My company is having a reshuffle and I'm applying for my boss' job as he's moved up the ladder. The new role would give me a chance to move our development team into the 21st century and I'd like to make sure that: I can provide sensible suggestions in the interview to get the job so I can fix the team If I get the job I can actually enact some changes to actually improve the lives of the developers and their output. I want to know what I can suggest to improve the way we work, because I think it's a mess but every time I've suggested a change it's been shot down because any time spend implementing the change would be time that isn't spent developing software. Here is the state of play at the moment: My team consists of 3-4 developers (Mainly Java but I do some .Net work) Each member of the team is usually works on 2-3 projects at a time We are each responsible for the entire life cycle of the project from design to testing. Usually only one person works on a project (Although we have the odd project that will have more than one person working on it.) Projects tend to be bespoke to single customer, or are really heavilly reliant on a particular customer environment. We have 2-3 "Products" which we evolve to meet customer requirements. We use SVN for source control We don't do continuous integration (I'd like to start) We use a really basic bug tracker for internal issue tracking (I'd like to move to an issue/task management system) Any changes that bring a sudden dip in revenue generation will probably be rejected, the company isn't structured for development most of the rest of the technical team's jobs can be broken down to install this piece of hardware, configure that piece of hardware and once a job is done it's done and you never have to look at it again. This mentality has crept into development team because it's part of the company culture.

• Need clarification concerning Windows Azure

  - by SnOrfus

  I basically need some confirmation and clarification concerning Windows Azure with respect to a Silverlight application using RIA Services. In a normal Silverlight app that uses RIA services you have 2 projects: App App.Web ... where App is the default client-side Silverlight and app.web is the server-side code where your RIA services go. If you create a Windows Azure app and add a WCF Web Services Role, you get: App (Azure project) App.Services (WCF Services project) In App.Services, you add your RIA DomainService(s). You would then add another project to this solution that would be the client-side Silverlight that accesses the RIA Services in the App.Services project. You then can add the entity model to the App.Services or another project that is referenced by App.Services (if that division is required for unit testing etc.) and connect that entity model to either a SQLServer db or a SQLAzure instance. Is this correct? If not, what is the general 'layout' for building an application with the following tiers: UI (Silverlight 4) Services (RIA Services) Entity/Domain (EF 4) Data (SQL Server)

• 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?

• Why is Software Engineering not the typical major for future software developers?

  - by FarmBoy

  While most agree that a certain level of Computer Science is essential to being a good programmer, it seems to me that the principles of good software development is even more important, though not as fundamental. Just like mechanical engineers take physics classes, but far more engineering classes, I would expect, now that software is over a half century old, that software development would begin to dominate the undergraduate curriculum. But I don't see much evidence of this. Is there a reason that Software Engineering hasn't taken hold as an academic discipline?

• 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?

• Submitting Java Code with Junit unit test

  - by LivingThing

  I have mostly work on simple java programs and compiled and run it with eclipse on Windows. So, i have no experience of using command prompt for compiling Java projects and do not have much info about what actually happens beneath the play button in Eclipse. Now i have to submit a Java application which will have basic operation on XML. My project also will have (JUnit) Unit Test. My question is related to submission of this Project. Which files would be necessary to submit the code. So, it executes properly? Does chosing eclipse as an IDE or junit as a unit testing framweork produces any dependenices i.e the executor of the program should have eclipse/libraries to execute the program on his machine?

• Best practices for web page styling with CSS?

  - by adifire

  I have a website to design. I have information on how the page should look and interact. The problem is I'm not good in front-end design, and have put many many hours to get the hang of the stuff. Currently, i am getting the CSS from sample sites in github and use them to style my site, which seems to be Not a ethical way. Question: how do you style webpages? Are there some really good tools? I would be deeply appreciated if a detailed answer will bee provided or link to wiki will work as well.

• Designing application flow

  - by Umesh Awasthi

  I am creating a web application in java where I need to mock the following flow. When user trigger a certain process (add product to cart), I need to pass through following steps Need to see in HTTP Session if user is logged in. Check HTTP Session if shopping cart is there If user exist in HTTP Session and his/her cart do not exist in HTTP Session Get user cart from the database. add item to cart and save it to HTTP session and update cart in DB. If cart does not exist in DB, create new cart and and save in it HTTP Session. Though I missed a lot of use cases here (do not want question length to increase a lot), but most of the flow will be same as I described in above steps. My flow will start from the Controller and will go towards Service Layer and than ends up in the DAO layer. Since there will be a lot of use cases where I need to check HTTP session and based on that need to call Service layer, I was planning to add a Facade layer which should be responsible to do this for me like checking Session and interacting with Service layer. Please suggest if this is a valid approach or any other best approach can be implemented here? One more point where I am confused is how to handle HTTP session in facade layer? do I need to pass HTTP session object each time I call my Facade or any other approach can be used here?

• Must-do activities for a team leader, and time managing them

  - by MeLight

  This is a two part question Part one: I'm leading a small team of developers of mixed skills (juniors and seniors). I'm sometimes feeling that I focus too much on my own code, instead of seeing the big the picture, and managing the team. What would you say the most crucial non-coding activities for a team leader, related to his team members? Part two:Given that I know what other (non-coding stuff) I should be doing, what is a good time division between my own code writing and managing the other team members (code reviews, whiteboarding, meetings etc).

• Coded ui to measure performance

  - by Mike Weber

  I have been tasked with using coded UI to measure performance on a proprietary windows desktop application. The need is to measure how long it takes for the next page/screen to display after a user clicks on a control. For example - a user enters their ID and PW and clicks sign-in. The need is to measure how long it takes for the next screen to display when the user clicks the sign-in button. I understand the need to define what indicates the screen is loaded and ready for use. One approach is to use control.WaitForControlReady and use BeginTimer/EndTimer. Is coded ui a dependable and accurate way of measuring time? Is WaitForControlReady the best method to determine when a control is ready for use?

• Adding page title to each page while creating a PDF file using itextsharp in VB.NET

  - by Snowy

  I have recently started using itextsharp and gradually learning it. So far I created a PDF file and it seems great. I have added a table and some subtables as the first table cells to hold data. It is done using two for loops. The first one loops through all data and the second one is each individual data displayed in columns. The html outcome looks like the following: <table> <tr> <td>Page title in center</td> </tr> <tr> <td> <table> <tr> <td>FirstPersonName</td> <td>Rank1</td> <td>info1a</td> <td>infob</td> <td>infoc</td> </tr> </table> </td> <td> <table> <tr> <td>SecondPersonName</td> <td>Rank2</td> <td>info1a</td> <td>infob</td> <td>infoc</td> <td>infod</td> <td>infoe</td> </tr> </table> </td> <td> <table> <tr> <td>ThirdPersonName</td> <td>Rank2</td> <td>info1a</td> <td>infob</td> <td>infoc</td> <td>infod</td> <td>infoe</td> <td>infof</td> <td>infog</td> </tr> </table> </td> </tr> </table> For page headings, I added a cell at the top before any other cells. I need to add this heading to all pages. Depending on the size of data, some pages have two rows and some pages have three rows of data. So I can not tell exactly when the new page starts to add the heading/title. My question is how to add the heading/title to all pages. I use VB.net. I searched for answer online and had no success. Your help would be greatly appreciated.

• Backend devs put down by user stories

  - by Szili

  I planned to slice in backend development into to the user stories vertically. But a backend guy on our team started to complain that this makes their work invisible. My answer was that at the sprint planning and review meetings we discuss backend tasks in front of stakeholders so it makes it visible, and maintaining a high quality during the project will result a slower startin pace than other teams, but we will have a stable velocity during the project. And velocity is highly visible to stakeholders. He still insist having stories like: "As a developer I need to have a domain layer so I can encapsulate business logic." How can I solve the issue before it pollutes the team? The root of the issue is that our management systematically consider backend work as invisible and call backed devs miners, or other pejorative terms.

• Determine whether a link points to a file on local host or foreign domain [migrated]

  - by user107157

  This has been a burning question for me ever since and I think it's interesting enough to discuss it on the forums. As most will know, in websites we include anchor links, stylesheets, script files (javascript) and images. For anchor links we use the form <a href="..." /> For stylesheets we may use the form <link rel="stylesheet" type="text/css" href="..." /> For javascript we may use <script src="..." /> For images we use <img src="..." /> So, the question is this: How do we know that what is in the link pointer (i.e. replacing the ... in each example) is a local file or a foreign entity? To make it clear, lets say I create a local file named "ashish.com". Now, my purpose is to create a link so that anybody who clicks on it may download it. So, my code would be thus: <a href="ashish.com">Download It</a> But this makes it ambiguous. I could also be referring to a website named "ashish.com" So, how does the computer magically know which one I mean? Or does it even know this? What would happen in such a scenario?
