I was browsing through the Amazon.com Bookstore and I came across the book "Functional Programming for Java Developers". I know some very basic Functional Programming and have been programming in Java for 3 years. I would like to know is Functional Programming even possible in Java?
Given C++ gained lambdas with C++11, will there be any LINQ like higher order function library officially supported later? Or is there already such a library used in production quality code? Obviously I'm not expecting the SQL-like expression tree based LINQ query syntax in C++. I am talking about the lambda based one....
I have 10,000 addresses from a city, which all have a region field in the database. When a new address is entered, then I want my software to automatically detect the region of the address . I think it should be implemented with some sort of machine learning algorithm. How can I do this? And with every newly inserted a...
In a similar vein as the How can open source projects be successful without documentation about their design or architecture? question, I'm curious: Why are so many libraries so lacking in end user documentation? My view is this: Most everyone agrees that reading source code is more difficult than writing source code...
I'm a newly graduate programmer and just got hired before my graduation. In the office, I used to create and revise modules of some applications developed by other programmers in our company. The problems I encountered with their applications are: Unnormalized database at it's best, they've broken all the rules of dat...
We have modularized our API into some independent components. Independent meaning these can be built via Maven and used as dependencies for other projects such as webapps. Now, to use this API, there needs to be an intermediate processing class which does a translation of the client data model into the callee (compone...
I'm a web developer working in a team of three developers and one designer. It's now about five months that we've implemented the agile scrum software development methodology. But I have a weird feeling I just wanted to share in this site. One important factor in human life is decision-making process. However, there is...
Hello and I'm apologizing in advance if this question doesn't fit programmers section of stackexchange. I'll try to clarify what the problem is by telling a story where the problem originates from. I'm working in a small company (8 people) where we have developers, sys admins and staff that handles day to day calls. Th...
I've wanted to learn C++ for awhile and took AP Computer Programming in High School (back when it was C++ and not Java). I enjoy C and just haven't found the time to learn C++ or I'll just fall back on C# where I'm much more productive. My question is this: given that C++ '11 has been approved (although I know not ful...
Do you know if the size of the database (number of tables used) is a factor when choosing between Hibernate and JDBC? Why or why not? In my particular case, I am evaluating Hibernate and JDBC for interacting with Oracle database for a small web app.
Are there any risks in giving out distribution certification/private key/provisioning profile to a freelancer? The freelancer needs to build the binary for me to submit (I am okay with this because I don't own the source code of the app), I just want to know if there is any risk involved in sending the distribution cer...
I am finishing my project and in my thesis I am explaining why I used an MVC pattern to build my website, and have stated the advantages of designing it this way. However, if I had not used MVC and had built my website from scratch with all the functions for data, processing, and display into each page, what would that...
I am completely new to Android development and have been reading many articles on the Android site and elsewhere.

So, what would I need to write "Hello world" on the iPod Touch on boot? Make that the entire operating system? Which compiler would I use, how would the graphics be done...? Can this be done without too much effort? I know writing an Assembly boot loader isn't that hard...
Including customizable, JavaScript-based scrollbars (and scrolling functionality in general, i.e. bind the control to the mouse scroll wheel) in your webapp can be a great temptation. However all solutions I could find were developed by individuals (which can equal lack of formal or future support). In addition I fail ...
I have been working on a new project. The project works like this: The end user can access a webapp using a link and he can add multiple systems on his network and manage that particular systems details. My part involves the front end and the webserver, which is done in python. My python actually communicates with anot...
If this title is ambiguous, feel free to change it, I don't know how to put this in a one-liner. Example: Let's assume you have a html template which contains some custom tags, like <text_field />. We now create a page based on a template containing more of those custom tags. When a user wants to edit the page, he sees...
One issue I think I am going to run into with my integration testing is having multiple tests accessing the same database. While this is not a problem now, I know we have multiple applications here that access the same database and I am just trying to think of a way to prevent this issue before it happens. An idea I h...
Alan kay in his paper, The power of Context pdf link, page 8, enumerates some of his motivations for dynamic objects.

My company has created a modular PHP framework over the years, beginning long before PHP 5.3 added namespaces. Recently, we decided to start using namespaces in our library's new code, and we intend to namespace old code eventually. However, we have a few issues we are trying to work out to determine if adding namespac...
So, why do websites have to ask (spoken) language and country when the browser can tell them that? Edit: Specifically, I mean why not use the accept-language section in the http header, set by the language settings in the browser, not based on the IP address. This question focuses the websites that put up a wall, forc...

in "Notes on Programming in C", in section "Complexity", Rob Pike writes: Most programs are too complicated - that is, more complex than they need to be to solve their problems efficiently. Why? Mostly it's because of bad design, but I will skip that issue here because it's a big one. .../... Does anyone know ...
In the case of a newly designed functional language, consider e.g. the not equals operator, spelled /= as is common among functional languages. Of course this operator is also known as != in C family languages, and <> in SQL et al. It would be easy to make the parser accept these as synonyms, in the hope of cutting dow...
I've always felt lucky to work in a small programming team. I think the most I've worked with is 11 programmers. What is it like working on a project with hundreds of developers? Thousands? What does scale and what doesn't? EDIT: Thanks for all the responses! There seem to be very few positives: possible to work on...
Is creating a scripting language for my own personal learning experience worth it? The reason I ask is that there are so many programming languages available already, I know mine will never have any actual use other than providing a good learning experience. I do, however, see drawbacks with just trying to make a scri...
I've been programming for a few years and I began in Java, and in my time I've found many different sources claiming Java to be an inferior language in some way or another. I'm well aware that each language has it's strengths and weaknesses, but a lot of things I've read about Java seem to be dated. The most often cit...
There are a lot of books on domain specific languages (DSLs). Such books talk about compilers, interpreters, parsing, lexing, semantic analysis, and other various bits someone needs to implement a DSL. I already know how to implement a DSL; I've implemented several. However, several such DSLs have been monsters to work...
I just started writing some ruby in my spare time and am currently using Netbeans 7 with the Ruby and Rails plugin v0.111. I'm primarily a Java programmer coming from IntelliJ and Eclipse. One downside of my Ruby programming setup is that my Netbeans isn't very helpful when it comes to code completion. This seems due t...

In another question, I asked about why I feel scrum turns active developers into passive developers, and it seems that the overall problem is not scrumy (related to scrum), and rather it's related to the bad implementation of scrum. So, here I have some questions about the scope of the responsibilities of PO (product o...
How do you recursively delete paths of the data that your app created? The deleting process itself is trivial. The question is, do you do extra validation? And if so, what kind? From one point of view, maybe it's simply an uncomfortable task to do, but on the other, imagine if the program has a bug and something passes...

Hypothetical: I’m based in the UK. I’ve developed an application only to discover after it has gone live, that someone else has filed a US Patent application for similar software. I don’t know if the patent will actually be granted, since the software-functionality has probably already existed long before now. Defi...
As a young software engineer, I often hear other colleagues talk about the days of punch cards and "computers as big as the room." The earliest memories of computers that I have involve MS DOS and Windows 3.1. My question is, are there still any companies, academic centers, or government agencies that still use mainfra...
Possible Duplicate: How do you keep track of the authors of code?

First off, this question goes beyond my example (don't want this to be too localized or migrated to Stack Overflow) but I've come across this when thinking about something I wanted to try in C so I thought I'd use that as an example.

This is for the freelancers. In my past life as a full-time employee, I was involved in hiring and interviewed a good number of developers. I learned that it was much more valuable to see a developer work through a problem, however small, than to talk about experience, etc. Now I'm working as a freelancer/consultant. O...
I am new to static analysis of code. My application has a Cyclomatic complexity of 17,754. The application itself is only 37,672 lines of code. Is it valid to say that the complexity is high based on the lines of code? What exactly is the Cyclomatic complexity saying to me?
I have been familiarizing myself with LISP for self improvement purposes. One of the things I have noticed is that LISP is much more within the paradigm of Mathematics than say C. The syntax and design structure seems to echo directly the actual mathematical model of an algorithm. It doesn't make sense to me why even g...
Objective-C features nice object orientation, simplicity, elegance, and (as a superset of C), low level ability. It could seem like the simple, modern alternative to C++ that many people look for and try to find in Go. But it is just used at Cocoa and post-NextSTEP environments, and even in this case is seen more as a ...
A philosophical discussion has come up in my department that I'd like p.se's opinion on. We're a 6 person development department inside a 60 person IT shop. All other departments are growing FAST, and ours has been the same size (and not fully booked at that size) for a few years. My manager, and old-school mainframe g...
Could a class be a first-class object? If yes, how would the syntax for dynamically creating new classes look like? To narrow the question - how would you give this functionality while keeping language consistent? For example how you create reference for new type. Do you make reference first-class object too and then...
I invested most my time and resources in programming, and now I think it's time I should invest some time in learning about user interface design, user experience, and usability. What are some good resources about usability and designing user interfaces? I'm mainly looking for more theoretical topics, such as color the...
This post by Jamis Buck about keeping Rails controllers skinny has always stuck with me. I have an app in which a zip file consisting of an XML file and some images is uploaded and used to create the model (mostly from the xml file, which points to the images). Should all the code dealing with extracting the files from...
I was looking through various APIs and SDKs, when I realized that I couldn't really tell the difference between something called an API and something called an SDK. Both of them are, conceptually, a way for your program to interface with and control the resources provided by another piece of software, whether that othe...
I'm working on a small project which will only have one user at a time since it's a local application (developed in WPF and C#).

I am sure this question has been asked many times. However, I like to ask it again with the intention of what is the future of these languages. I was first introduced to Groovy and really liked it.

I'm about to extend a system containing two separate systems. Or domains, if we see the system as a domain level. Today One domain is used internally.

I've been watching an interview with Herb Sutter on Channel9 and he mentioned at the end of the video that left to right language syntax would be on the top on his whishlist for a future C++ standard(although he acknowledges that modifying C++ in that way would pretty much make for a completely different beast). Apart ...
This just struck me as an oversight by Microsoft. Since arrays and other data-structures within the .NET framework begin from zero (zero-based) why don't we have a line 0 within the code view in Visual Studio? Ponder that one :-)

Should the usage of Dependency Injection and an Inversion of Control container remove all occurrences of the "new" keyword from your code?

I have developed for Android for half a year or so and it is going quite well. I found the learning curve steep in the beginning, but then I somehow got the idea of it all and now I don't have to fight so much anymore.

I must confess that I was not so strong in data structures when I graduated out of college. Throughout the campus placements during my graduation, I've witnessed that most of the biggie tech companies like Amazon, Microsoft etc focused mainly on data structures.

As a professional Java programmer, I've been trying to understand - why the hate toward Java for modern web applications?

I work at a company that has repeatedly cut the sizes of its development team, to the point that previous 10-man teams are now down to one developer per product (and a couple of testers shared between 5 products).

There seems to be a growing trend for CMS systems to manage not only data capture and workflow, but to be an end-to-end product that manages presentation and end user content (like comments/forums).

I'm going to ask what is probably quite a controversial question: "Should one of the most popular encodings, UTF-16, be considered harmful?" Why do I ask this question?

From what I can tell, most developers will use heavy jQuery DOM manipulation tactics to deliver their updated AJAX views.
