  - by AdityaGameProgrammer

  As developers how much time, or do you spend time, In learning the hidden features tricks of your operating system ? How important do you feel is this for productivity in day to day programming? tasks. What do you mean when you list knowledge of an OS in your resume? What are your most useful hidden -less known features For example: A common problem of How can i open the cmd window in a specific location a do it yourself solution in say xp and what to do if something breaks Or are these something you look into as and when you find the need to do so?

• Site/Project to convert in Java web pages as it is now with complete functionality, look and feel.

  - by pirzada

  I have completed a web site Surfrainbow using ASP.NET and working fine. Completely dynamic with back-end management and Ajax support. This site has to be 100% same as in Java considering look and feel. Conversion is for learning purpose. I am new to Java and learning it fast. I don't want to know how to learn Java. Just want to know what is needed for this project to work in Java related technologies. Want to know How would you handle this project. My questions are 1 - What technologies I will be needing to make this project like Servlets, JSP, JSF etc? 2 - What is needed for Ajax support. Is JQuery supported :)? 3 - What should be used for MVC? 4 - ASP.NET has master pages to simplify design. Anything like this in Java? 5 - Which IDE is best for Java development. JDeveloper/NetBeans? Anything else you can share. Thanks

• using GNU GPL v2 software as pointers to solution to problem

  - by Patrick

  I am coding a PHP serial access class and have been taking pointers from the PHP-serial class on Google Code (here). That class is based on PHP 4 and I'm creating a PHP 5 class that allows more functionality and is specific to some business demands I have. There is no code copied and I have done all the coding. Does the class I'm writing fall under the Google Code's GPL or am I free to select a license that I feel is appropriate? I'm not sure of the standard that applies to licensing when you are only looking to another work for pointers.

• Why do so few large websites run a Microsoft stack?

  - by realworldcoder

  Off the top of my head, I can think of a handful of large sites which utilize the Microsoft stack Microsoft.com Dell MySpace PlentyOfFish StackOverflow Hotmail, Bing, WindowsLive However, based on observation, nearly all of the top 500 sites seem to be running other platforms.What are the main reasons there's so little market penetration? Cost? Technology Limitations? Does Microsoft cater to corporate / intranet environments more then public websites? I'm not looking for market share, but rather large scale adoption of the MS stack.

• Do you think Scala will be the dominant JVM langauge, ie be the next Java? [on hold]

  - by user1037729

  From what I've read about Scala do far I think it has some nice features but I do not think it should be "the next Java". It might however end up being the next Java (due to fashion rather than fact) but lets not hope it does not... To me adds a lot of complexity over Java which is a simple and scalable language. Scala Pattern matching allows you to perform some type/value checking in a more concise way, this is possible in Java, Scala's pattern matching has a limit to it, you cannot continuously match deeper and deeper down the object graph, so why not just stick to Java and use decent invariants? Scala provides tuples, easy enough to make in Java, create a static factory method and it all reads nicely too. Scala provides mixins, why not just use composition? I believe Scala implicit's are bad, they can lead to code becoming complex and hard to maintain, explicitness is good. Scala provides closures, well they will be in Java 8 too. Scala has lazy keyword for lazy instantiation, this is easy enough to do in Java by calling a getter which creates the instance when needed, no hidden magic here. Scala can be used with AKKA, well so can Java, there is an Java AKKA implementation. Scala offers addition functional features but these can all be created in Java, there are many frameworks with have implemented functional features in Java. All in all Scala seems to offer is addition complexity and thats it...

• Why is database developer pay so high? [closed]

  - by user433500

  Just wondering why someone would get 10k+ in some area in US for just writing queries and creating tables. While the average salary for someone who does scripting, object oriented programming, J2EE and database all together is only ~12K in new york city. Is there similar opportunities in cities like new york where only doing database gets one 10K+? What is the rational of companies paying such a high salary to consultants for just writing simple queries? I am sure college grad can do that with ease and will be quite satisfied with a 60k+ pay for a couple of year. Does location really matter so much?

• What is a dotted pair's analogy in other Lisp implementations?

  - by octopusgrabbus

  What is Scheme's dotted pair construct analogous to in other Lisp implementations? I can make a vector or list quite easily, and understand those in Clojure, even though the syntax is a little different, like Clojure's vectors use square brackets []. However, seeing a dotted pair for the first time threw me. It almost looks like it is an implementation of of map. I'm not looking for a discussion, but more for use or the dotted pair equivalent in other Lisp dialects, like Clojure, or even Python. Thanks.

• Name user object and user table correctly

  - by Marc

  It's maybe simple but I think about this every time I build a new application. How do you name the class for the current user of the application and for the orm class of the user table? Usually I have something like CurrentUser: Logged-in user, stored in session, info for last activity etc User: ORM Class (C# EF CodeFirst, but it doesn't matter) And yes, they could have the same name in different namespaces, but I don't really like that.

• ORM and component-based architecture

  - by EagleBeek

  I have joined an ongoing project, where the team calls their architecture "component-based". The lowest level is one big database. The data access (via ORM) and business layers are combined into various components, which are separated according to business logic. E.g., there's a component for handling bank accounts, one for generating invoices, etc. The higher levels of service contracts and presentation are irrelevant for the question, so I'll omit them here. From my point of view the separation of the data access layer into various components seems counterproductive, because it denies us the relational mapping capabilities of the ORM. E.g., when I want to query all invoices for one customer I have to identify the customer with the "customers" component and then make another call to the "invoices" component to get the invoices for this customer. My impression is that it would be better to leave the data access in one component and separate it from business logic, which may well be cut into various components. Does anybody have some advice? Have I overlooked something?

• Seeking advice on system documentation

  - by Shadders

  I have a rating engine (it is basically an algorithm) which when I started had no formal documentation. We have created a functional specification/decomposition which is our business level document but now I need something more technical (a technical specification). What I am struggling to understand is what that document looks like, what format it should be in and to what level of detail we should go into. We are in the process of commenting all of the code. We also have a rough document called a Blueprint which reflects the flow of the model and is written in pseudo code. Is the combination of this blueprint and the model comments sufficient as a Technical Specification?

• Where to start building a BaaS

  - by Wesley

  I'm building a Cloud Platform, and the next phase of design involves building an extensible BaaS back end. (see http://youtu.be/lNi-05-PyEw) The reason I think we can attempt this, is there are dozens of these kinds of extensible back end data proxy's popping up almost daily at this point, which tells me the enabling technology is there to build one from scratch in a few months. I'd like to start in the right area: What kind of Dev background should I look for? What kind of tech stack should I build on? What kind of costs can I expect in terms of man-hours, etc... I know there isn't one right answer here, but I think this is the right sub to post this in, and credit will go towards to most constructive answer.

• Common practice in handling bounce message

  - by foodil

  At now I mainly create a mail account separately (with different domain name [email protected]) and i add this mail as one return path. So the bounce message will only go to that mailbox and i parse the mail message one by one to check the failure receipent and the error code, then i convert the error code to the actual error message. Finally, the error message and the fail receipent's mail are post to my system and let my system user check the bounce information. Is it a common practice? Since i am worry about the mail other from bounce message have sent to my mail box, that would be a disaster if i parse them without filter them out, but how can i filter out between bounce message and normal mail? Thank you for any kind of help.

• Options for Opensource license?

  - by foodil

  I am choosing a license for my open source software and I've learned about GPL, EBMS and BSD. GPL seems to be most popular one. The problems are: Would anybody kindly name a few popular opensource licenses? Since I do not see any EBMS BSD license is popular. Are there any chart or table that have list out the advantages/disadvantages of using anyone? Why is the GPL always the license developers choose from, what are its benefits? Thank you.

• What issues carry the highest risk in a software project?

  - by Mehrdad

  Clearly, software projects are different from other industries in terms of many things like for instance, quality assurance, project progress measurement, and many other things. Unique characteristics of software projects also makes the risk management process unique. Lots of issues in a project might lead it to unacceptable delay or failure to deliver business value. They might even make a complete disaster in the project. What are the deadliest risk factors in a software project? How to analyze, prevent and handle them? Particularly, I'm interested in the issues that you can detect from the beginning and you should keep an eye on (for example, you might be told about a third-party API that the current application uses and lacks documentation). Please share your experiences if they are relevant.

• Should one comment differently in functional languages

  - by Tom Squires

  I'm just getting started with functional programming and I'm wondering the correct way to comment my code. It seems a little redundant to comment a short function as the names and signature already should tell you everything you need to know. Commenting larger functions also seems a little redundant since they are generally comprised of smaller self-descriptive functions. What is the correct way to comment a functional program? Should I use the same approach as in iterative programming?

• Java Developers: Is Ant still in the "main stream" for builds? Do we push new developers to learn it?

  - by Sam Goldberg

  We have been slowly replacing batch command files (windows .bat) which were simply jarring up the classes compiled in the developers IDE, with more comprehensive Ant builds (i.e. get from CVS, clean compile, jar, archive, email, etc.) I've spent a lot of time learning (and debugging issues) with Ant, so I'm most comfortable using it for these tasks. But I wonder if Ant is still in as wide usage as it was when I first started learning, or whether "the world has moved on" to something newer (and maybe slicker). (I've started to see more Maven build stuff distributed, which I've never used, for example.) The practical import of this question, is whether I push new developers to learn Ant, or whether they should be learning something else for builds? I'm never too on top of the trends, so it would be great to hear from other Java developers what they think is the best build tool, and what they think new developers should be learning.

• Any interesting thesis topic?

  - by revers

  Hi, I study Computer Science at Technical University of Lodz (in Poland) with Computer Game and Simulation Technology specialization. I'm going to defend BSc thesis next year and I was wondering what topic I could choose but nothing really interesting is coming to my mind. Maybe You could help me and suggest some subjects related to programming graphics, games or simulations? (or maybe something else that is interesting enough :) ). I would be very grateful for any suggestion!

• Failed Project: When to call it?

  - by Dan Ray

  A few months ago my company found itself with its hands around a white-hot emergency of a project, and my entire team of six pulled basically a five week "crunch week". In the 48 hours before go-live, I worked 41 of them, two back to back all-nighters. Deep in the middle of that, I posted what has been my most successful question to date. During all that time there was never any talk of "failure". It was always "get it done, regardless of the pain." Now that the thing is over and we as an organization have had some time to sit back and take stock of what we learned, one question has occurred to me. I can't say I've ever taken part in a project that I'd say had "failed". Plenty that were late or over budget, some disastrously so, but I've always ended up delivering SOMETHING. Yet I hear about "failed IT projects" all the time. I'm wondering about people's experience with that. What were the parameters that defined "failure"? What was the context? In our case, we are a software shop with external clients. Does a project that's internal to a large corporation have more space to "fail"? When do you make that call? What happens when you do? I'm not at all convinced that doing what we did is a smart business move. It wasn't my call (I'm just a code monkey) but I'm wondering if it might have been better to cut our losses, say we're not delivering, and move on. I don't just say that due to the sting of the long hours--the company royally lost its shirt on the project, plus the intangible costs to the company in terms of employee morale and loyalty were large. Factor that against the PR hit of failing to deliver a high profile project like this one was... and I don't know what the right answer is.

• Referencing external javascript vs. hosting my own copy

  - by Mr. Jefferson

  Say I have a web app that uses jQuery. Is it better practice to host the necessary javascript files on my own servers along with my website files, or to reference them on jQuery's CDN (example: http://code.jquery.com/jquery-1.7.1.min.js)? I can see pros for both sides: If it's on my servers, that's one less external dependency; if jQuery went down or changed their hosting structure or something like that, then my app breaks. But I feel like that won't happen often; there must be lots of small-time sites doing this, and the jQuery team will want to avoid breaking them. If it's on my servers, that's one less external reference that someone could call a security issue If it's referenced externally, then I don't have to worry about the bandwidth to serve the files (though I know it's not that much). If it's referenced externally and I'm deploying this web site to lots of servers that need to have their own copies of all the files, then it's one less file I have to remember to copy/update.

• Difference between () and [] in Perl6 [migrated]

• What do you do when your naming convention clashes with your language?

  - by Jon Purdy

  Okay, this is one of those little things that always bugged me. I typically don't abbreviate identifiers, and the only time I use a short identifier (e.g., i) is for a tight loop. So it irritates me when I'm working in C++ and I have a variable that needs to be named operator or class and I have to work around it or use an abbreviation, because it ends up sticking out. Caveat: this may happen to me disproportionately often because I work a lot in programming language design, where domain objects may mirror concepts in the host language and inadvertently cause clashes. How would you deal with this? Abbreviate? (op) Misspell? (klass) Something else? (operator_)

• Should you put personal beliefs in your program?

  - by TheLQ

  Recently I've found two examples of programmer's personal beliefs in programs that have removed or crippled useful functionality uTorrent using KB (rarely used) vs Kb (what most ISPs and other programs use as their metric) in their current connection speed. Various attempts by others and me to give options to at least give an option to show in Kb have ended with "ISPs should use KB" Kleopatra (gpg4Win key manager) not having PGP Key Pictures since they "give a false sense of security" and "increase the size of certificates". While the latter is true, the former is debatable. Both of these hurt the program and its usefulness to me. uTorrent's forums used to be filled with people saying they have 10 Mb download pipe but uTorrent only goes up to 2 MB (not knowing that Mb != MB), and with feature requests to show in Mb. Kleopatra has lost usefulness to me since I don't have the functionality to add pictures to PGP keys. These all are political statements; developers attempting to make change in, in their minds important, issues. But should this come at a cost to end user functionality? If a programmer heavily believes X but everyone else believes Y, should the programmer refuse to add support for Y because in their mind X is horrible? In short, should a programmer make political statements in their program?

• Anyone been successful changing their career without having to start over from scratch?

  - by Awaken

  I posted a similar question on careeroverflow, but stackoverflow is just way more active and has way more users, so hopefully someone out there can help answer. I am currently an embedded developer in the defense/aerospace world for a big company. While I like the benefits and the pay, it just isn't keeping me happy. The Paul Graham article: How To Do What You Love really struck home. The problem I face are my golden handcuffs. When I look at jobs out there, they all want 5+ years experience in that language with expertise in framework/tool/server A,B,C, etc... I have worked in C and C++ on the job (in a real-time embedded environment) with some small things in C# and Java. I'm learning Ruby now to expand my knowledge, but I don't consider myself an expert in anything right now. I'd love to work on desktop applications or web apps. Is it possible for someone like me to make the switch without going back to the start line? I'd love to leave the huge bureaucracy and work with some great developers. I'd be willing to work late and take a modest pay cut, but that isn't so clear just from a resume. For those that have altered their career path, how did you do it? For those people who are in charge of hiring, what can I do to help myself?

• Why are most websites optimized for viewing in portrait mode?

  - by NVM

  I simply cannot figure this out. Almost all monitors have an aspect ratio where width is much bigger than the height and yet almost all websites are designed exactly for the other way round? I am not really a web developer and am just experimenting stuff at the moment but this madness baffles me!!! Edit: The point is not that I would like to limit the height of a website. The point is that I'd wat it to somehow fill all available space when I have my 1920x1080 in landscape mode. Edit 2: See this to understand what I am saying
