• Java EE Basic Training with Yakov Fain

  - by reza_rahman

  Those of us that have been around Java/Java EE for a little while sometimes tend to forget that Java is still an ever expanding ecosystem with many newcomers. Fortunately, not everyone misses this perspective, including well-respected Java veteran Yakov Fain. Yakov recently started a free online video tutorial series focused on Java and Java EE for absolute beginners. The first few parts of the series focused on Java SE but now Yakov is beginning to cover the very basics of Java EE. In a recent video he covered: The basics of the JCP, JSRs and Java EE How to get started with GlassFish 4 The basics of Servlets Developing Java EE/Servlets using Eclipse and GlassFish The excellent video is posted below. The slides for the tutorial series generally are available here. If there are folks you know that would benefit from this content, please do pass on word. Even if you are an experienced developer, it sometimes helps to sit back and review the basics... It's quite remarkable that someone of Yakov's stature took the time out to create content for absolute beginners. For those unaware, Yakov is one of the earliest Java champions and one would be very hard pressed to match his many contributions to the Java community. The tutorial demonstrates his continued passion, commitment and humility.

• How do I cluster strings based on a relation between two strings?

  - by Tom Wijsman

  If you don't know WEKA, you can try a theoretical answer. I don't need literal code/examples... I have a huge data set of strings in which I want to cluster the strings to find the most related ones, these could as well be seen as duplicate. I already have a set of couples of string for which I know that they are duplicate to each other, so, now I want to do some data mining on those two sets. The result I'm looking for is a system that would return me the possible most relevant couples of strings for which we don't know yet that they are duplicates, I believe that I need clustering for this, which type? Note that I want to base myself on word occurrence comparison, not on interpretation or meaning. Here is an example of two string of which we know they are duplicate (in our vision on them): The weather is really cold and it is raining. It is raining and the weather is really cold. Now, the following strings also exist (most to least relevant, ignoring stop words): Is the weather really that cold today? Rainy days are awful. I see the sunshine outside. The software would return the following two strings as most relevant, which aren't known to be duplicate: The weather is really cold and it is raining. Is the weather really that cold today? Then, I would mark that as duplicate or not duplicate and it would present me with another couple. How do I go to implement this in the most efficient way that I can apply to a large data set?

• Dealing with under performing co-worker

  - by PSU_Kardi

  I'm going to try to keep this topic as generic as I can so the question isn't closed as too specific or whatever. Anyway, let's get to it. I currently work on a somewhat small project with 15-20 developers. We recently hired a few new people because we had the hours and it synched up well with the schedule. It was refreshing to see hiring done this way and not just throwing hours & employees at a problem. Alas, I could argue the hiring process still isn't perfect but that's another story for another day. Anyway, one of these developers is really under performing. The developer is green and has a lot of bad habits. Comes in later than I do and leaving earlier than I am. This in and of itself isn't an issue, but the lack of quality work makes it become a bit frustrating. When giving out tasking the question is no longer, what can realistically be given but now becomes - How much of the work will we have to redo? So as the project goes on, I'm afraid this might cause issues with the schedule. The schedule could have been defined as a bit aggressive; however, given that this person is under performing it now in my mind goes from aggressive to potentially chaotic. Yes, one person shouldn't make or break a schedule and that in and of itself is an issue too but please let's ignore that for right now. What's the best way to deal with this? I'm not the boss, I'm not the project lead but I've been around for a while now and am not sure how to proceed. Complaining to management comes across as childish and doing nothing seems wrong. I'll ask the community for insight/advice/suggestions.

• The (non) Importance of Language

  - by Eric A. Stephens

  Working with a variety of clients on EA initiatives one begins to realize that not everyone is a fan of EA. Specifically, they are not a fan of the "a-word". Some organizations have abused this term with creating and assigning the title to just about anyone who demonstrates above average prowess with a particular technology. Other organizations will assign the title to those managers left with no staff after a reorg. Some companies, unfortunately, have simply had a bad go of it with regard to EA...or any "A" for that matter. What we call "EA" is almost irrelevant. But what is not negotiable for those to succeed in business is to manage change. That is what EA is all about. I recall sitting in Zachman training led by himself. He posits the only organizations that don't need EA (or whatever you want to call it) are those that are not changing. My experience suggests those orgs that aren't changing aren't growing. And if you aren't growing, you're dying. Any EA program will not succeed unless there is a desire to change. No desire to change suggests the EA/Advisor/Change Agent should just walk the other way.

• Game planning and software design? I feel that UML is not convenient

  - by user1542

  In my university, they always emphasize and hype about UML design and stuff, in which I feel it is not going to work well with game structure design. Now, I just want a professional advice on how should I begin my game designing? The story is I have some skill in programming and have done many minor game such as getting some 2D platformer working to some extend. The problems that I find about my program is the poor quality design. After coding for a while, things start to break down due to poor planning (When I add new feature, it tends to make me have to recode the whole program). However, to plan everything out without a single design flaw is a bit too ideal. Therefore, any advice to how should I plan my game? How should I put it into visible pictures, so that me and my friends are able to overview the designs? I planned to start coding a game with my friend. This is going to be my first teamwork, so any professional advices would be a pleasure. Is there any other alternatives than UML? Another question is how does "prototyping" normally looks like?

• Isn't Java a quite good choice for desktop applications?

  - by tactoth

  At present most applications are still developed with C++, painfully. Lack of portability, in compatible libraries, memory leaks, slow compilation, and poor productivity. Even if you pick only a single from these shortages, it's still a big headache. However the surprising truth is that C++ remains the first choice for desktop applications. Compared to C++ Java has lots of advantages. The success in server side development shows that the language itself is good, Swing is also thought to be as programmer friendly as the highly recognized QT framework (No, never say even a single word about MFC!). All the disadvantages of C++ listed above has a solution in Java. "Performance!", Well that might still be the problem but to my experience it's a slight problem. I'd been using Java to decode some screen video and generate key frames. The video has a duration of more than 1 hour. The time spent on an average machine is just 1 minute. With C++ I don't expect even faster speed. In recent days there are many news on the JIT performance improvements, that make us feel Java is gradually becoming very suitable for desktop development, without people realizing it. Isn't it?

• "That's cool. But it would be even better if..."

  - by Geertjan

  I recently talked to some NetBeans users who were interested in a demonstration of the features that will be part of NetBeans IDE 7.2. (See the 7.2 New and Noteworthy for the full list.) One of the new features I demonstrated was this one. In an interface declaration, NetBeans IDE 7.2 will provide a hint, as can be seen in the sidebar below: When the lightbulb is clicked, or Alt-Enter is pressed, this will be shown: When the hint is invoked, the user will see this: And then the user will be able to enter the name of a class, and the name of a package, and assuming the defaults above are taken, a class with this content will be generated: package demo; public class WordProcessorImpl implements WordProcessor {     @Override     public String process(String word) {         throw new UnsupportedOperationException("Not supported yet.");     } } When I demonstrated the above, the response from the audience was: "That's cool. But it would be even better if..." it was possible to implement an interface into an existing class. it was possible to select a class and specify the interfaces that it should implement. it was possible, in the context of a NetBeans Platform application, to specify the module where the class should be implemented. So I created some issues: Implement an interface into an existing class http://netbeans.org/bugzilla/show_bug.cgi?id=210804 Select class and specify interfaces to implement http://netbeans.org/bugzilla/show_bug.cgi?id=210805 Allow user to select module for generating implementation http://netbeans.org/bugzilla/show_bug.cgi?id=210807

• Should developers be involved in testing phases?

  - by LudoMC

  Hi, we are using a classical V-shaped development process. We then have requirements, architecture, design, implementation, integration tests, system tests and acceptance. Testers are preparing test cases during the first phases of the project. The issue is that, due to resources issues (*), test phases are too long and are often shortened due to time constraints (you know project managers... ;)). So my question is simple: should developers be involved in the tests phases and isn't it too 'dangerous'. I'm afraid it will give the project managers a false feeling of better quality as the work has been done but would the added man.days be of any value? I'm not really confident of developers doing tests (no offense here but we all know it's quite hard to break in a few clicks what you have made in severals days). Thanks for sharing your thoughts. (*) For obscure reasons, increasing the number of testers is not an option as of today. (Just upfront, it's not a duplicate of Should programmers help testers in designing tests? which talks about test preparation and not test execution, where we avoid the implication of developers)

• Can I make a business in teaching home users Ubuntu [on hold]

  - by Dorgaldir

  I was thinking about a way to bring Ubuntu to the bigger public, since it has great advantages for people in the lower income class that only use a PC for basic usage. They pay for a windows licence without actually needing windows because 95% of what they do is in a browser and the other 5% is typing a word document or making a simpel Excel sheet. So for these people something like Ubuntu is ideal, they can prolong the life of their old PC or laptop with Ubuntu and thus saving extra money. And as we all know, saving money is not only interesting for the lowest of income but for most of us. But when I talk to people they don't want to use Ubuntu because they know Windows and they don't know this, they'll complain about having to adapt to windows 8 but adapting to Ubuntu seems a bridge too far. But what if someone in the neighborhood gave simple Ubuntu courses. Teaching people about Ubuntu, stuff like: What is an OS What is Ubuntu How do I obtain Ubuntu How do I install Ubuntu How do I set up my email in Ubuntu How do I make a text document in Ubuntu How do I update my facebook wall in Ubuntu ... Simple basic PC usage, but within Ubuntu. But as much as I would like to work for free all day, I can't do this for free for people outside of my social circle. So I was wondering if it is possible to make a business and make money with giving Ubuntu courses, or are their steps to be taken before this is possible. However... Do I need an Ubuntu or Canonical license? Do I need to get a certificate? Do I have to make some kind of deal or contract with Canonical? Just to be clear this is all just an idea in my head at this point, I'm just gathering information. I'm not a teacher at a school, just a programmer that is thinking about options in life. Thanks in advance!

• Serve up syntactic XHTML5 using the text/html MIME type?

  - by cboettig

  I have a site currently written with HTML5 tags. I'd like to be able to parse the site as XML, with support for namespaces, etc, to facilitate programmatic extraction of data. Currently I have <!DOCTYPE html> and <meta charset="utf-8"> Which I gather is equivalent in HTML5 to explicitly setting the content-types as <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> for my current setup. In order to serve XML it sounds like the right thing to do is <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> Should I also change my Content-Type to <meta http-equiv="content-type" content="application/xhtml+xml; charset=iso-8859-1" /> Or is that not necessary? What is the advantage of having content-type be "application/xhtml+xml"? What is the disadvantage? (Sounds like it may break internet explorer rendering of the site? but maybe that information is out of date now?) Many thanks!

• Should sanity be a property of a programmer or a program?

  - by toplel32

  I design and implement languages, that can range from object notations to markup languages. In many cases I have considered restrictions in favor of sanity (common knowledge), like in the case of control characters in identifiers. There are two consequences to consider before doing this: It takes extra computation It narrows liberty I'm interested to learn how developers think of decisions like this. As you may know Microsoft C# is very open on the contrary. If you really want to prefix your integer as Long with 'l' instead of 'L' and so risk other developers of confusing '1' and 'l', no problem. If you want to name your variables in non-latin script so they will contrast with C#'s latin keywords, no problem. Or if you want to distribute a string over multiple lines and so break a series of indentation, no problem. It is cheap to ensure consistency with restrictions and this makes it tempting to implement. But in the case of disallowing non-latin characters (concerning the second example), it means a discredit to Unicode, because one would not take full advantage of its capacity.

• Checking validation of entries in a Sudoku game written in Java

  - by Mico0

  I'm building a simple Sudoku game in Java which is based on a matrix (an array[9][9]) and I need to validate my board state according to these rules: all rows have 1-9 digits all columns have 1-9 digits. each 3x3 grid has 1-9 digits. This function should be efficient as possible for example if first case is not valid I believe there's no need to check other cases and so on (correct me if I'm wrong). When I tried doing this I had a conflict. Should I do one large for loop and inside check columns and row (in two other loops) or should I do each test separately and verify every case by it's own? (Please don't suggest too advanced solutions with other class/object helpers.) This is what I thought about: Main validating function (which I want pretty clean): public boolean testBoard() { boolean isBoardValid = false; if (validRows()) { if (validColumns()) { if (validCube()) { isBoardValid = true; } } } return isBoardValid; } Different methods to do the specific test such as: private boolean validRows() { int rowsDigitsCount = 0; for (int num = 1; num <= 9; num++) { boolean foundDigit = false; for (int row = 0; (row < board.length) && (!foundDigit); row++) { for (int col = 0; col < board[row].length; col++) { if (board[row][col] == num) { rowsDigitsCount++; foundDigit = true; break; } } } } return rowsDigitsCount == 9 ? true : false; } I don't know if I should keep doing tests separately because it looks like I'm duplicating my code.

• In a specification, should I describe what a product does (ideally) or what it should/must do?

  - by Arlaud Pierre

  I'm writting a German specification (I'm not German). Differences may appear for this process in different cultures, especially in the terminology, but usually here's the idea: The client writes his needs and wishes in a document, called a scope statement or requirements document. The supplier tries to understand the actual need of the client (which might be different to what was written and to what the client meant to say and to what the client thinks he needs, etc.) The supplier writes a specification for the product, which should fill the client's need. The specification needs to be precise enough for the product to be made (ambiguity problems occur). The client and the supplier can check whether they have understood each other, and discuss details of the product. The client agrees with the specification (or at least its current iteration) and the supplier is ready to start the work. (it may of course be expected of you to disagree with this process, but this is irrelevant to my problem): I'm now somewhere around the last two steps and I've been criticized because I wrote what the product must do, and not what it will do ideally. Usually along the lines of The product must be able to perform task A And I was expected to write The product performs task A This is a simple word play, but I feel saying what the product does, while the product isn't even on the way to be made yet, is wrong. I would tend to consider a specification as a contract of what the product is expected to do (what it must do and how it should do it), and not what it does. Said differently, I feel this is the specification and not the manual of the end product…… Should I say what the product must do or what it does?

• Using Bulk Operations with Coherence Off-Heap Storage

  - by jpurdy

  Some NamedCache methods (including clear(), entrySet(Filter), aggregate(Filter, …), invoke(Filter, …)) may generate large intermediate results. The size of these intermediate results may result in out-of-memory exceptions on cache servers, and in some cases on cache clients. This may be particularly problematic if out-of-memory exceptions occur on more than one server (since these operations may be cluster-wide) or if these exceptions cause additional memory use on the surviving servers as they take over partitions from the failed servers. This may be particularly problematic with clusters that use off-heap storage (such as NIO or Elastic Data storage options), since these storage options allow greater than normal cache sizes but do nothing to address the size of intermediate results or final result sets. One workaround is to use a PartitionedFilter, which allows the application to break up a larger operation into a number of smaller operations, each targeting either a set of partitions (useful for reducing the load on each cache server) or a set of members (useful for managing client result set sizes). It is also possible to return a key set, and then pull in the full entries using that key set. This also allows the application to take advantage of near caching, though this may be of limited value if the result is large enough to result in near cache thrashing.

• From release to business

  - by geneotech

  So let's say that I've finished programming a simple, indie MMO game similiar to Tibia. I've got a stable server application that is ready to launch, i've got a tested bug-free working client application that is ready to play and the game's official website (ready to host) with payment system and client that is ready to download for free. Let's say none of them break copyright laws, and no matter how impossible it sounds, let's for now say it's true. My game divides accounts into two groups - free and premium. If someone gets premium, he's granted access to all possible game features, that of course, need server authorisation to work properly. Let's say that the "premium account" can be bought on the website for a fixed money/month. Free accounts mean that everyone can actually play, but without paying, you get limited access. This is what the mentioned payment system will be for. Well, I'm completely novice to these business entities issues, so in short: what, in terms of law, are steps from here to the state where my game earns money in a fully legal way ? Also, is there for example, something like verification if game gives the user what it actually offers when paying on its website ? I live in Europe, if it changes something.

• How do spambots work?

  - by rlb.usa

  I have a forum that's getting hit a lot by forum spambots, and of course the best way to defeat something is to know thy enemy. I'll worry about defeating those spambots later, but right now I'd like to know more about them. Reading around, I felt surprised about the lack of thorough information on the subject (or perhaps my ineptness to input the correct search terms for better google results). I'm interested in learning all about spambots. I've asked on other forums and gotten brush-off answers like "Spambots are always users registering on your site." How do forum spambots work? How do they find the 'new user registration' page? (I'm especially surprised because some forums don't have a dedicated URL for this eg, www.forum.com/register.html , but instead use query strings or even other methods invisible to the URL bar) How do they know what to enter into each 'new user registration' field? How do they determine what's a page they can spam / enter data into and what is not? Do they even 'view' this page at all? ..If not, then I'd assume they're communicating with the server directly - how is - this possible? How do they do it? Can forum spambots break CAPTCHAs? Can they solve logic questions (how?)? Math questions? Do they reverse-engineer client-side anti-bot validation scripts? Server-side scripts? What techniques are still valid to prevent them? Where do spambots come from? Is someone sitting behind the computer snickering as they watch their bot destroy site after site? Or are they snickering as they simply 'release' it onto the internet somehow? Are spambots 'run' by an infected computer somewhere? Do they replicate themselves? etc

• ADF - Now with Robots!

  - by Duncan Mills

  I mentioned this briefly in a tweet the other day, just before the full rush of OOW really kicked off, so I though it was worth re-visiting. Check out this video, and then read on: So why so interesting? Well - you probably guessed from the title, ADF is involved. Indeed this is as about as far from the traditional ADF data entry application as you can get. Instead of a database at the back-end there's basically a robot. That's right, this remarkable tape drive is controlled through an ADF using all your usual friends of ADF Faces, Controller and Binding (but no ADFBC for obvious reasons). ADF is used both on the touch screen you see on the front of the device in the video, and also for the remote management console which provides a visual representation of the slots and drives. The latter uses ADF's Active Data Framework to provide a real-time view of what's going on the rack. . What's even more interesting (for the techno-geeks) is the fact that all of this is running out of flash storage on a ridiculously small form factor with tiny processor - I probably shouldn't reveal the actual specs but take my word for it, don't complain about the capabilities of your laptop ever again! This is a project that I've been personally involved in and I'm pumped to see such a good result and,  I have to say, those hardware guys are great to work with (and have way better toys on their desks than we do). More info in the SL150 (should you feel the urge to own one) is here.

• Implementing unit testing at a company that doesn't do it

  - by Pete

  My company's head of software development just "resigned" (i.e. fired) and we are now looking into improving the development practices at our company. We want to implement unit testing in all software created from here on out. Feedback from the developers is this: We know testing is valuable But, you are always changing the specs so it'd be a waste of time And, your deadlines are so tight we don't have enough time to test anyway Feedback from the CEO is this: I would like our company to have automated testing, but I don't know how to make it happen We don't have time to write large specification documents How do developers get the specs now? Word of mouth or PowerPoint slide. Obviously, that's a big problem. My suggestion is this: Let's also give the developers a set of test data and unit tests That's the spec. It's up to management to be clear and quantitative about what it wants. The developers can put it whatever other functionality they feel is needed and it need not be covered by tests Well, if you've ever been in a company that was in this situation, how did you solve the problem? Does this approach seem reasonable?

• Allowing client to select data to return via REST interface

  - by CMP

  I have a rest service that is essentially a proxy to a variety of other services. So if I call GET /users/{id} It will get their user profile, as well as order history, and contact info, etc... all from various services, and aggregates them into one nice object. My problem is that each call to a different service has the potential to add time to the original request, so we would rather not get ALL the data ALL of the time if a particular client does not care about all of the pieces. A solution I have arrived at is to do something like this: GET /users/{id}?includeOrders=true&includeX=true&includeY=true... That works, and it allow me to do only what I need to, but it is cumbersome. We have added enough different data sources that there are too many parameters for that style to be useful. I could do something similar with a single integer and a bitmask or something, but that only makes it harder to read, and it does not feel very Restful. I could break it down into multiple calls so they would need to call /users/{id}/orders and /users/{id}/profile separately, but that sort of defeats the purpose of an aggregating proxy, who's purpose is to make clients jobs easier. Are there any good patterns that can help me return just enough data for each client, without making it too difficult for them to filter and select what they want?

• Which metric/list should be used to evaluate whole software development team?

  - by adt

  Title might be seem vague, so let me tell you a little bit history what i am trying to clarify question. I have been hired as a consultant for a corporate's small developement divison ( The company also owns a couple of software dev. companies) My ex manager runs a BI team, with reportes, analyts and developers. He asked me to evaluate overall design, software developement process and code quality . Here what i found, Lots of copy/paste code everywhere ( no reuse ) Even though they have everything TFS, VS Ultimate etc, No Build process , No Cruise Control.net / team city... No unit tests Web Pages with 3700 lines of code, Lots of huge functions ( which can be divided into smaller one's ) No naming convention both db and c# code No 3r party or open source project No IoC No Seperation Of Concerns No Code Quality Check ( NDepend or FxCope or nothing ) No Code Review No Communication within the team They claim they wrote an application framework ( 6 months 3 persons), but I would hardly call a framework ( of course no unit test, there are some but all commented out). Framework contains 14 projects but there are some projects with 1 file 20 lines of code . Honestly, what people are doing fixing bug all thr day( which will provide more bugs eventually), they are kind of isolated from community, some team members even dont know github or stackoverflow they probably went there with google but they dont know about it. So here is question, Is This list ok ? Or am i being picky? Since I dont have any grudge against them, I just want to be fair, honest and I would like to hear you suggestions, before I would submit this list. And since this list also will be review by software division's manager, I dont want any heart break or something like this. http://www.hanselman.com/altnetgeekcode/ For example I would love to such lists, i cant make references. Thanks in advance.

• Value my C++ knowledge

  - by PirateOwh

  I have only followed antiRTFM tutorials and read 2 books So, I'll list the things I know better : basic input output and all the variables : integers ( signed unsigned ), float, double, char arrays if, for, while, switch functions, and passing variables to functions and return type thing classes and the concept of oop with separating declaration and definition in the header and in the source pointers so this and some more i think is all i know of C++.. But, i need some exercises to test my knowledge because i want to move on to the library SDL, so I don't know if i should feel ready or not to move on to something totally different.. I feel I should know the basics for good at least. So the question is : How can i value my c++ knowledge? Is there any online tests? Is there any GDD ( Game Design Document ) for free to use and see if i can manage to do it so "i'd pass" ? ( I'm saying GDD since ill move on to SDL and try to make my own game ) When should I move to SDL? What are ALL the things I should "master" ( master is a big word to say.. but so you understand what i mean ) before moving on ? Please I'm really in need of expert advice. I think my question is detailed so i hope you understand what i mean and can give me a good reply. Thanks for the help!
