• Using Clojure instead of Python for scalability (multi core) reasons, good idea?

  - by Vandell

  After reading http://clojure.org/rationale and other performance comparisons between Clojure and many languages, I started to think that apart from ease of use, I shouldn't be coding in Python anymore, but in Clojure instead. Actually, I began to fill irresponsisble for not learning clojure seeing it's benefits. Does it make sense? Can't I make really efficient use of all cores using a more imperative language like Python, than a lisp dialect or other functional language? It seems that all the benefits of it come from using immutable data, can't I do just that in Python and have all the benefits? I once started to learn some Common Lisp, read and done almost all exercices from a book I borrowod from my university library (I found it to be pretty good, despite it's low popularity on Amazon). But, after a while, I got myself struggling to much to do some simple things. I think there's somethings that are more imperative in their nature, that makes it difficult to model those thins in a functional way, I guess. The thing is, is Python as powerful as Clojure for building applications that takes advantages of this new multi core future? Note that I don't think that using semaphores, lock mechanisms or other similar concurrency mechanism are good alternatives to Clojure 'automatic' parallelization.

• Learning OO for a C Programmer

  - by Holysmoke

  I've been programming professionally in C, and only C, for around 10 years in a variety of roles. As would be normal to expect, I understand the idioms of the language fairly well and beyond that also some of the design nuances - which APIs to make public, who calls what, who does what, what is supposed to reentrant and so on. I grew up reading 'Writing Solid Code', it's early C edition, not the one based on C++. However, I've never ever programmed in an OO language. Now, I want to migrate to writing applications for iPhone (maybe android), so want to learn to use Objective-C and use it with a degree of competence fitting a professional programmer. How do I wrap my head around the OO stuff? What would be your smallest reading list suggestion to me. Is there a book that carries some sort of relatively real world example OO design Objective-C? Besides, the reading what source code would you recommend me to go through. How to learn OO paradigm using Objective-C?

• What should I "forget" when going to Javascript?

  - by ElGringoGrande

  I went from C=64 Basic and assembler to FORTRAN and C to C++ and Java. Professionally I started in Visual Basic for applications then to Visual Basic 4, 5, 6. After that VB.NET AND C# with some Java here and there. I have played with Ruby and Python and found both fun. During each step I never felt like I had to forget what I had learned before. I always felt like I was just learning better and/or slightly different ways of doing things but the difference was not major. The difference was like the difference between American, Australian and British English. (Maybe assembler was Latin and FORTRAN was Spanish.) But now I am using JavaScript to do real, actual work. (Before used it as a "Scripting" language pure a simple.) And I just feel like I have to forget some things to become proficient in it. It feels like some old Egyptian language. What should I forget? Is it just that code organization is different (no real classes so no one class one file)? Or is it something more basic?

• Setting up Clojure Project And Sub Projects

  - by octopusgrabbus

  This is primarily a lein question about setting up a major project and its sub-projects, and is not intended to be a discussion question. Instead, I am interested in either a pointer to documentation or to a Clojure/lein best practices link. I have a municipal property assessments application that splits two master flies into different subset files, depending on whether a billing transfer is taking place or we want to batch update new accounts, rather than making our assessment department enter new accounts once in their system and then again in the tax collection system. My application is going to be large enough, that I can see a common library lein project with support functions, like splitting apart the files, and then individual lein projects that use the common library. Should the lein projects be set up at the same level and support included through the project.clj/core.clj files? Is there an advantage to creating lein new projects underneath a major project? Is there a problem with combing all functions in one project? I can probably make my one core.clj contain all flavors of the program, but coming from a C/C++ and Python background, I would prefer to have a lot of little projects.

• Adjusting the rate of movement of different objects on the same timer

  - by theUg

  I have a series of objects moving along the straight lines. I want to implement slight changes of velocity of each of the object. Constraint is existing model of animation. I am new to this, and not sure if it is the best way to accommodate varying speeds, but what do I know? It is a Java application that repaints the panel every time the timer expires. Timer is set via swing.Timer object that is set by timer delay constant. Every time the game is stepped objects’ coordinates advanced by an increment constant. Most of the objects are of the same class. Is there fairly easy way to refactor existing system to allow changing velocity for an individual object? Is there some obvious common solution I am not aware about? Idea I am having right now is to set timer delay fairly small, and only move objects every so many cycles of animation so that the apparent speed can be adjusted by varying how often they get moved. But that seems fairly involved, and I do not think it is the most elegant solution in terms of performance what with repainting the whole frame every 3-5 milliseconds. Can it be done by advancing the objects so many (varying) times during the certain interval (let’s say 35ms for something like 28fps), and use repaint() method to redraw just individual object? Do I need to mess with pausing animation for smoothness at higher redraw rates? Is it common practise to check for collision at larger step interval, but draw animation a lot more frequently?

• Dojo and Separate JavaScript File

  - by Bunch

  For a project I needed to use the ArcGIS API for some mapping. To use this you need to use Dojo but in this case all it really comes down to is adding some require lines and a addOnLoad on your web page. At first everything was working great, the maps rendered and the various layers would populate as needed. Once it was working I started moving the various javascript functions into their own files to keep everything nice and neat. Then the problems started, mainly the map would not show up any more. So that was a pretty big problem. Luckily the fix was pretty simple, just move the dojo.addOnLoad line into it’s own script tag. If I had the dojo.addOnLoad in the same script block as the various require lines it would not work as expected. Works: <script type="text/javascript" language="javascript" src="javascript/test.js" />     <script type="text/javascript">       dojo.require("esri.map");       dojo.require("esri.tasks.locator");       dojo.require("esri.tasks.query");       dojo.require("esri.tasks.geometry");  </script>  <script type="text/javascript">      dojo.addOnLoad(init);  </script> Does not work: <script type="text/javascript" language="javascript" src="javascript/test.js" /> <script type="text/javascript">       dojo.require("esri.map");       dojo.require("esri.tasks.locator");       dojo.require("esri.tasks.query");       dojo.require("esri.tasks.geometry");       dojo.addOnLoad(init); </script> Technorati Tags: JavaScript,Dojo

• emacs keybindings

  - by Max

  I read a lot about vim and emacs and how they make you much more productive, but I didn't know which one to pick. Finally when I decided to teach myself common lisp, the decision was straight forward: everybody says that there's no better editor for common lisp, than emacs + slime. So I started with emacs tutorial and immediately I ran into something that seems very unproductive to me. I'm talking about key bindings for cursor keys: forward/backward: Ctrl+f, Ctrl+b up/down: Ctrl+p, Ctrl+n I find these bindings very strange. I assume that fingers should be on their home rows (am I wrong here?), so to move cursor forward or backward I should use my left index finger and for up and down right pinky and right index fingers. When working with any of Windows IDEs and text editors to navigate text I usually place my right hand in a position so that my thumb is on the right ctrl and my index, ring and middle fingers are on the cursor keys. From this position it is very easy and comfortable to move cursor: I can do one-character moves with my 3 right fingers, or I can press ctrl with my right thumb and do word-moves instead. Also I can press shift with my left pinky and do single-character or word selections. Also it is a very comfortable position to reach PgUp, PgDn, Home, End, Delete and Backspace keys with my right hand. So I have even more navigation and selection possibilities. I understand that the decision not to use cursor keys is to allow one to use emacs to connect to remote terminal sessions, where these keys are not supported, but I still find the choice of cursor keys very unfortunate. Why not to use j, k, i, l instead? This way I could use my right hand without much finger stretching. So how is emacs more productive? What am I doing wrong?

• How should I architect a personal schedule manager that runs 24/7?

  - by Crawford Comeaux

  I've developed an ADHD management system for myself that's attempting to change multiple habits at once. I know this is counter to conventional wisdom, but I've tried the conventional for years & am now trying it my way. (just wanted to say that to try and prevent it from distracting people from the actual question) Anyway, I'd like to write something to run on a remote server that monitors me, helps me build/avoid certain habits, etc. What this amounts to is a system that: runs 24/7 may have multiple independent tasks to run at once may have tasks that require other tasks to run first lets tasks be scheduled by specific time, recurrence (ie. "run every 5 mins"), or interval (ie. "run from 2pm to 3pm") My first naive attempt at this was just a single PHP script scheduled to run every minute by cron (language was chosen in order to use a certain library, but no longer necessary). The logic behind when to run this or that portion of code got hairy pretty quick. So my question is how should I approach this from here? I'm not tied to any one language, though I'm partial to python/javascript. Thoughts: Could be done as a set of scripts that include a scheduling mechanism with one script per bit of logic...but the idea just feels wrong to me. Building it as a daemon could be helpful, but still unsure what to do about dozens of if-else statements for detecting the current time

• Does Agile force developers to work more?

  - by Shooshpanchick

  Looking at common Agile practices it seems to me that they (intentionally or unintentionally?) force developer to spend more time actually working as opposed to reading blogs/articles, chatting, coffee breaks and just plain procrastinating. In particular: 1) Pair programming - the biggest work-forcer, just because it is inconvenient to do all that procrastination when there are two of you sitting together. 2) Short stories - when you have a HUGE chunk of work that must be done in e.g. a month, it is pretty common to slack off in the first three weeks and switch to OMG DEADLINE mode for the last one. And with the little chunks (that must be done in a day or less) it is exact opposite - you feel that time is tight, there is no space for maneuvering, and you will be held accountable for the task pretty soon, so you start working immediately. 3) Team communication and cohesion - when you underperform in a slow, distanced and silent environment it may feel ok, but when at the end of the day at Scrum meeting everyone boasts what they have accomplished and you have nothing to say you may actually feel ashamed. 4) Testing and feedback - again, it prevents you from keeping tasks "99% ready" (when it's actually around 20%) until the deadline suddenly happens. Do you feel that under Agile you work more than under "conventional" methodologies? Is this pressure compensated by the more comfortable environment and by the feeling of actually getting right things done quickly?

• CoffeeScript - inability to support progressive adoption

  - by Renso

  First if, what is CoffeeScript?Web definitionsCoffeeScript is a programming language that compiles statement-by-statement to JavaScript. The language adds syntactic sugar inspired by Ruby and Python to enhance JavaScript's brevity and readability, as well as adding more sophisticated features like array comprehension and pattern matching.The issue with CoffeeScript is that it eliminates any progressive adoption. It is a purist approach, kind of like the Amish, if you're not borne Amish, tough luck. So for folks with thousands of lines of JavaScript code will have a tough time to convert it to CoffeeScript. You can use the js2coffee API to convert the JavaScript file to CoffeeScript but in my experience that had trouble converting the files. It would convert the file to CoffeeScript without any complaints, but then when trying to generate the CoffeeScript file got errors with guess what: INDENTATION!Tried to convince the CoffeeScript community on github but got lots of push-back to progressive adoption with comments like "stupid", "crap", "child's comportment", "it's like Ruby, Python", "legacy code" etc. As a matter of interest one of the first comments were that the code needs to be re-designed before converted to CoffeeScript. Well I rest my case then :-)So far the community on github has been very reluctant to even consider introducing some way to define code-blocks, obviously curly braces is not an option as they use it for json object definitions. They also have no consideration for a progressive adoption where some, if not all, JavaScript syntax will be allowed which means all of us in the real world that have thousands of lines of JavaScript will have a real issue converting it over. Worst, I for one lack the confidence that tools like js2coffee will provide the correct indentation that will determine the flow of control in your code!!! Actually it is hard for me to find enough justification for using spaces or tabs to control the flow of code. It is no wonder that C#, C, C++, Java, all enterprise-scale frameworks still use curly braces. Have never seen an enterprise app built with Ruby or PhP.Let me know what your concerns are with CoffeeScript and how you dealt with large scale JavaScript conversions to CoffeeScript.

• Joomla: Cross site link boxes

  - by Dean Smith

  I am currently evaluating Joomla for use on the the rebuild of our corporate website. One of the features our designs have is spaces for what we've been calling widgets. These widgets include common ones for each page, contact us boxes, section navigation, that all seem pretty easy to implement. The other widgets we would us to highlight specific pages within the site relevant to the one you are on, and are therefore different for each article. We've called these link widgets and these are a pretty common site on many websites. I'm honestly at a bit of a loss as to how to do this with Joomla. From a CMS perspective I'd like to allow users to just select which three link widgets they want when editing the article and have some way of creating the widgets within the CMS as well. Editing the link widget would allow setting a title, a bit of text and selecting the page that it links to. Am I going to be able to do this with Joomla, and if I can roughly how to I go about it ?

• Designs for outputting to a spreadsheet

  - by Austin Moore

  I'm working on a project where we are tasked to gather and output various data to a spreadsheet. We are having tons of problems with the file that holds the code to write the spreadsheet. The cell that the data belongs to is hardcoded, so anytime you need to add anything to the middle of the spreadsheet, you have to increment the location for all the fields after that in the code. There are random blank rows, to add padding between sections, and subsections within the sections, so there's no real pattern that we can replicate. Essentially, anytime we have to add or change anything to the spreadsheet it requires a many long and tedious hours. The code is all in this one large file, hacked together overtime in Perl. I've come up with a few OO solutions, but I'm not too familiar with OO programming in Perl and all my attempts at it haven't been great, so I've shied away from it so far. I've suggested we handle this section of the program with a more OO friendly language, but we can't apparently. I've also suggested that we scrap the entire spreadsheet idea, and just move to a webpage, but we can't do that either. We've been working on this project for a few months, and every time we have to change that file, we all dread it. I'm thinking it's time to start some refactoring. However, I don't even know what could make this file easier to work with. The way the output is formatted makes it so that it has to be somewhat hardcoded. I'm wondering if anyone has insight on any design patterns or techniques they have used to tackle a similar problem. I'm open to any ideas. Perl specific answers are welcome, but I am also interested in language-agnostic solutions.

• Impact on SEO of adding categories/tags in front of the HTML title [closed]

  - by Mad Scientist

  Possible Duplicate: Does the order of keywords matter in a page title? All StackExchange sites add the most-used tag of a question in front of the HTML title for SEO purposes. On Stackoverflow for example this is usually the programming language, so you end up with a title like python - How do I do X? This has obviously an enourmous benefit on SEO as the programming language is an extremely important keyword that is very often omitted from the title. Now, my question is for the cases where the tag isn't an important keyword missing from the title, but just a category. So on Biology.SE for example one would have questions like biochemistry - How does protein X interact with Y? or on Skeptics medical science - Do vaccines cause autism? Those tags are usually not part of the search terms, they serve to categorize the content but users don't use those tags in their searches. How harmful is adding tags that are not used in searches in terms of SEO? Is there any hard data on the impact this practise might have on SEO? The negative aspects I can imagine, but have no data to show that it is actually a problem are: I heard that search engines dislike keyword stuffing and this might trigger some defense mechanisms against that It's a practise associated with less reputable sites, a keyword in front that doesn't fit the actual title well might look suspicious to some users. It wastes precious space in the title shown in search results.

• Threading models when talking to hardware devices

  - by Fuzz

  When writing an interface to hardware over a communication bus, communications timing can sometimes be critical to the operation of a device. As such, it is common for developers to spin up new threads to handle communications. It can also be a terrible idea to have a whole bunch of threads in your system, an in the case that you have multiple hardware devices you may have many many threads that are out of control of the main application. Certainly it can be common to have two threads per device, one for reading and one for writing. I am trying to determine the pros and cons of the two different models I can think of, and would love the help of the Programmers community. Each device instance gets handles it's own threads (or shares a thread for a communication device). A thread may exist for writing, and one for reading. Requested writes to a device from the API are buffered and worked on by the writer thread. The read thread exists in the case of blocking communications, and uses call backs to pass read data to the application. Timing of communications can be handled by the communications thread. Devices aren't given their own threads. Instead read and write requests are queued/buffered. The application then calls a "DoWork" function on the interface and allows all read and writes to take place and fire their callbacks. Timing is handled by the application, and the driver can request to be called at a given specific frequency. Pros for Item 1 include finer grain control of timing at the communication level at the expense of having control of whats going on at the higher level application level (which for a real time system, can be terrible). Pros for Item 2 include better control over the timing of the entire system for the application, at the expense of allowing each driver to handle it's own business. If anyone has experience with these scenarios, I'd love to hear some ideas on the approaches used.

• The 2012 JAX Innovation Awards

  - by Janice J. Heiss

  A new article, now up on otn/java, titled “The 2012 JAX Innovation Awards” reports on  important Java developments celebrated by the Awards, which were announced in July of 2012. The Awards, given by S&S Media Group, aim to, "Reward those technologies, companies, organizations and individuals that make outstanding contributions to Java." The Awards fall into three categories: Most Innovative Java Technology, Most Innovative Java Company, and Top Java Ambassador. In addition, a finalist who did not win an award receives a Special Jury prize, "in acknowledgement of their unique contribution and positive impact on the Java ecosystem."The winners were: JetBrains for Most Innovative Java Company; Adam Bien as Top Java Ambassador; Restructure 101, created by Headway Software, as Most Innovative Technology; and Charles Nutter, Special Jury award. Each winner received a $2,500 prize. The five finalists in each category were invited to attend the JAX Conference in San Francisco, California. This year's winners each received a $2,500 prize. JetBrains Fellow, Ann Oreshnikova, listed her favorite JetBrains innovations: * Nullability annotations and nullability checker* CamelCase navigation and completion* Continuous Integration in grid (on multiple agents), in TeamCity* IntelliJ Platform and its language support framework* MPS language workbench* Kotlin programming languageWhen asked what currently excites him about Java, Adam Bien, winner of the Java Ambassador Award, expressed enthusiasm over the increasing interest of smaller companies and startups for Java EE. “This is a very good sign,” he said. “Only a few years ago J2EE was mostly used by larger companies -- now it becomes interesting even for one-person shows. Enterprise Java events are also extremely popular. On the Java SE side, I'm really excited about Project Nashorn.”Special Jury Prize Winner, Charles Nutter of Red Hat, remarked that, “JRuby seems to have hit a tipping point this past year, moving from ‘just another Ruby implementation’ to ‘the best Ruby implementation for X,’ where X may be performance, scaling, big data, stability, reliability, security, and a number of other features important for today's applications.

• BI Publisher : Formatting Issues

  - by Manoj Madhusoodanan

  While creating BI Publisher reports the formatting issues are quite common.Here I am discussing some common issues related to BIP report development. 1) First issue is related to column formatting.When you want to display some data which has leading zeros or trailing zeros after '.' in EXCEL output you will not get the desired output.But in PDF it will come as what you are expecting.This is not with the issue of your data. This is due to the unique nature of EXCEL cell format.When you are trying to put a text data in a cell with out making any change to cell format it will treat as number and it will truncate all leading zeros and all trailing zeros after '.' . So what you have to do is to convert that data into a format which EXCEL can treat as text. Eg: If you want to display 0020100 convert this data into ="0020100". Same way for 23789.02300 to ="23789.02300".   Note: This is applicable to EXCEL output only.If you have multiple output type apply it only for EXCEL. 2) Second is related to report size issue in PDF output type.If the number of columns are more and if you want to show most of the columns in one row andif it is a PDF output you can choose the paper size as Legal (8.5 x 14''). You will get more spaces in the template to accommodate more columns. 3) If your XML data contains special characters like &,<,> etc ..  pass the data to DBMS_XMLGEN.CONVERT function.It will replace special characters with corresponding XML notations. Eg: (a>b) & (c!=d) to  (a&gt;b) &amp; (c!=d)

• Thoughts on type aliases/synonyms?

  - by Rei Miyasaka

  I'm going to try my best to frame this question in a way that doesn't result in a language war or list, because I think there could be a good, technical answer to this question. Different languages support type aliases to varying degrees. C# allows type aliases to be declared at the beginning of each code file, and they're valid only throughout that file. Languages like ML/Haskell use type aliases probably as much as they use type definitions. C/C++ are sort of a Wild West, with typedef and #define often being used seemingly interchangeably to alias types. The upsides of type aliasing don't invoke too much dispute: It makes it convenient to define composite types that are described naturally by the language, e.g. type Coordinate = float * float or type String = [Char]. Long names can be shortened: using DSBA = System.Diagnostics.DebuggerStepBoundaryAttribute. In languages like ML or Haskell, where function parameters often don't have names, type aliases provide a semblance of self-documentation. The downside is a bit more iffy: aliases can proliferate, making it difficult to read and understand code or to learn a platform. The Win32 API is a good example, with its DWORD = int and its HINSTANCE = HANDLE = void* and its LPHANDLE = HANDLE FAR* and such. In all of these cases it hardly makes any sense to distinguish between a HANDLE and a void pointer or a DWORD and an integer etc.. Setting aside the philosophical debate of whether a king should give complete freedom to their subjects and let them be responsible for themselves or whether they should have all of their questionable actions intervened, could there be a happy medium that would allow the benefits of type aliasing while mitigating the risk of its abuse? As an example, the issue of long names can be solved by good autocomplete features. Visual Studio 2010 for instance will alllow you to type DSBA in order to refer Intellisense to System.Diagnostics.DebuggerStepBoundaryAttribute. Could there be other features that would provide the other benefits of type aliasing more safely?

• Is Scala ready for prime time?

  - by jayraynet

  Now that I've done a few trivial things with Scala (which I love for "hello world" and contrived applications!) I am left wondering.. part about maturity of the tools to support development, and part about general applicability. Are the toolsets ready? Is Scala appropriate for use on enterprise / business applications? Would "you" use it on a non-trivial project? Some of my (possibly unfounded) concerns would be: are the IDE and toolsets as rich as what we have to develop .net and java applications (eclipse for Scala seems limited compared to eclipse for java)? are the build / CI / testing toolsets able to effectively deal with Scala? how maintainable is the concise code that can be (encouraged?) written in the language? is it possible to find developers with Scala experience? is there enough critical mass to get help through on-line reference and books that are more than "intro" to the language? So bottom line - is the ecosystem mature enough to use now, or better off waiting to see how it evolves? EDIT: let's say "non-trivial" is a multi-year, multi-release, 10-20 developers project.

• c# scripting execution with xna (actions take more than 1 frame)

  - by user658091

  I'm trying to figure out how to implement c# scripting into my game (XNA with C#). I will be using C# as the scripting language. My question is, how to call functions that take more than 1 frame to finish? For example: class UserScript : Script { public override void execute(Game game) { //script must wait for dialog to be closed game.openDialog("This is a dialog"); //script should'nt wait for this int goldToGive = 100; goldToGive += 100; game.addGold(goldToGive); // //script should wait for cinematic to end game.startCinematic("name_of_cinematic"); //doesn't wait game.addGold(100); } } I found that you can do that with yield, but I'm not sure if it's the correct way (It's from 2010, the article mentioned no longer exists). http://stackoverflow.com/questions/3540231/implementing-a-simple-xml-based-scripting-language-for-an-xna-game Is yield the answer? If so, can anyone point me any examples/tutorials/books? I haven't found any regarding my situation. If not, what approach should I take? or am I better off with multi-threading?

• Building a complete program?

  - by Bob

  Reading books, watching videos, and reviewing tutorials is all very easy. Taking notes and actually learning the material may be slightly harder, but even then, anyone with a decent brain and a fair amount of interest, it's easy enough (not to mention, fun). The thing is, it doesn't really prepare you to write a full program or website. Let's say you're those teens (only in highschool, no true (college level) computer science or programming courses, and no real world experience), and you come out with Groupon. Or even Mark Zuckerburg, sure he was a genius, and he was a very capable programmer... but how? How do you recommend that people who are not necessarily new to programming, but new to programming real applications and real programmers go about developing it? What is the "development process" - especially for single programmers (or maybe 2-3 teens)? Also, as far as web development goes, what is the process? Was something like Facebook or Groupon written with a framework (like CodeIgniter or Zend for PHP)? Or do they develop their own frameworks? I'm not asking how to come up with a great idea, but how to implement great ideas in an effective way? Does anyone have advice? I've read a couple of books on both C and C++ (primarily the C Programming Language and the C++ Programming Language) and taken AP Computer Science (as well as read a few additional books on Java and OOP). I also have read a few tutorials on PHP (and CodeIgniter) and Python. But I'm still in highschool, and I'm technically not even old enough to work at an internship for a few more months.

• CLR and C# Learning Materials

  - by Gerry O'Brien

  Have you ever found that one book or resource that just brings it all home?  Seriously.  These are rare finds when you read the content and all the stars seem to align, you have those "Ah ha!" moments. Well, I have found that book and it is CLR via C#, Third Edition by Jeffrey Richter.  If you're not familiar with Wintellect, look them up.  This book is published by Microsoft Press and is the third edition of this title.  I'm in chapter 5 at the moment and already I have a better understanding of the CLR and how things work.  I'm a former Visual Basic MVP and C# is a language I learned as a result of projects I worked on at a software development company a few years ago.  Like a lot of VB programmers, I never went deep into the workings of the "behind the scenes" aspects and just focused on the applications. My next possible career move involves a deeper knowledge of the CLR and a .NET language.  This book is one that I will have my bookshelf for reference long after I have read that last page. Gerry

• 3D space game development

  - by user1693061

  I want to develop a 3D game (sci-fi type with spaceships) which can be played on multiplayer mode and by multiplayer i mean around 10 players for start as it will be a personal testing project and mostly educational. I have been searching for some days about the available languages and engines but i am kinda confused. Since i have been learning Java for my 1st year in I.T university and i have pretty good understanding i thought i would go with the Java language and develop that game on an applet so it could be played on a browser. After going through an applet game tutorial i understood how graphics work on an applet. So.. 1st question: Could an applet carry the burden of a 3D game especially on multiplayer? My thinking: It's a space game so the graphics should not be such a big problem since it wont be that crowded with entities apart from ships, planets and some effects. If the java applet is not the way for my project i would't mind "developing it on desktop"(i mean not making it a browser game). 2nd question: Should i use Unity engine for my purpose(space game)? If not name other language/engine combo.
