• From Java to Javascript? [duplicate]

  - by theGreenCabbage

  This question already has an answer here: Are there any OO-principles that are practically applicable for Javascript? 2 answers I am primarily a Java programmer. Because of its OO principles and the general paradigm of Java programming, like wrapping things in static variables, and having things return specific types, heavily aids me in "visualizing" a program. Instead of thinking of a big program, I can, instead, focus on smaller organized parts of my eventual program, and add functionality and build up from there. Thus, I have trouble programming in other languages. Or at least, I have not been able to program in the same ability as I do in Java compared to other languages. I know Javascript has OO principles, so I'd like to learn this language in a OO-based like I would program with Java. Is this possible?

• What most games would benefit from having

  - by Phil

  I think I've seen "questions" like this on stackoverflow but sorry if I'm overstepping any bounds. Inspired by my recent question and all the nice answers (Checklist for finished game?) I think every gamedev out there has something he/she thinks that almost every game should have. That knowledge is welcome here! So this is probably going to be an inspirational subjective list of some sorts and the point is that anyone reading this question will see a point or two that they've overlooked in their own development and might benefit from adding. I think a good example might be: "some sort of manual or help section. Of course it should be proportional to how advanced the game is. Some users won't need it and won't go looking for it but the other ones that do will become very frustrated if they can't remember how to do something specific that should be in the manual". A bad example might be "good gameplay". Of course every game benefits from this but the answer is not very helpful.

• A good language for c# dev to expand his mind [closed]

  - by Jan Kratochvil

  I have some free time on my hands and I was thinking about learning a new language. I do not plan to use it in my day-to-day job, but I rather want to expand my way of thinking to get a better sense where the dev world is heading from a language perspective and to don't get stuck in my way when programming by rather try new approaches. I was thinking either a functional language, like Haskell or F# (which is a bit more 'pragmatic from a .NET dev standpoint) or something dynamic (like Python, that in my oppinion has nicer syntax than Ruby). What can you recommend that is enjoyable, at least a bit practical, but most of all, new (from a c# dev perspective). I appreciate any answers.

• What's the point of Rabbit MQ? [duplicate]

  - by bad_boy

  This question already has an answer here: When to use Advanced Message Queuing Protocol like RabbitMQ? [closed] 2 answers First of all, let me say, I have no problem following tutorials. The problem is that I don't understand why even Rabbit MQ is ever needed. And there's no such explanation on tutorials - they only show what to do and how to use, but not when its usage is the case. Can you explain this? Why would you want to use Rabbit MQ? To solve what problem?

• How to prepare for an online job interview (maybe through Skype)?

  - by phunehehe

  I'm applying for a company far away and if I get an interview it will probably be done remotely. I have been searching for advices regarding this but all tips seem to be directed at face-to-face meetings (things like "shake hands firmly"). What are the differences? How can I make the best out of those differences? Update: This is a software developer position, so there's also something about technical questions (such as, I can Google anything that they ask ;) This question also applies to any freelancers who are dealing with customers, or recruiters who are interviewing remotely. I hope that makes it relevant to this site. It may also help if you keep answers programers-related.

• What significant lost steps forward in side tracks should be revived in the main stream of software?

  - by C.W.Holeman II

  In reading Alan Kay's question on Significant new inventions I was coming up with answers that were not new ideas but old ones that have been passed by in the main stream. So, what significant lost steps forward that happened in a side track should be revived in the main stream of software? These would be ideas that worked well in their context but a different context appeared and became dominant the context, even though it lacked the idea. It maybe that in the new dominant context one just cannot do something or it requires great effort to be exerted.

• Using static methods in objects PHP - is it advantage?

  - by RePRO

  I was reading some articles and discussions on the use of static methods on objects and it struck me how much the views differ. Someone say that using static methods is an advantage. Someone says that use is a big mistake. I wonder how is it? My question is when to use static methods and when not? I would like to hear answers from experts in this field (PHP OOP). This is because I know how it really is. The following code should be analogous. Just call the static method is simpler (my opinion): <?php class A { public function write($a) { echo $a; } } class B { public static function write($a) { echo $a; } } $a = new A; $a->write(5); // 5 B::write(5); // 5 ?> Thank you.

• Assemble static site from templates? (don't want to reinvent the wheel)

  - by raindog308

  I have a site that is 100% static content (no php, just some javascript). There's several "blocks" like the header, menu, footer, etc. that are the same on each page. Rather than do a lot of copy/pasting, I was thinking of some kind of template system where I could run a CLI command (in php, perl, python, shell, whatever) and have it replace all the block tags with the actual block text. I did see some answers in this question, but those seem oriented towards "we provide the style and layout, you provide the text". In my case, I have everything as far as layout, css, etc. - just want to do a glorified sed. Before I invent the wheel, I was wondering if there was a tool out there already.

• Verb+Noun Parsers and Old School Visual Novels [duplicate]

  - by user38943

  This question already has an answer here: How should I parse user input in a text adventure game? 6 answers Hi I'm working on a simple old school visual novel engine in Lua. Basically I have most of the code set up besides one important feature. The Text Parser. Lets get into how words are generally structured. In the screenshot I input the command "my wish is for you to die" --How would a human understand this? my = noun/object wish = verb is = connective_equator similar to = for = connective_object (for all objects of ..) you = noun/object to = connective_action similar to do die = verb --the computer can then parse this and understand it like this (pseudo example) my = user you = get_current_label() you = "Lost Coatl" wish = user_command user_command = for all_objects of "Lost Coatl" do die() end execute user_command() What other ways do videogames use text parsers, what would be the simplest way for a newbie coder such as myself?

• Why Android for new (micro) consoles?

  - by Klaim

  There are a lot of new (micro) consoles with Android inside coming soon or already there (OUYA for example). My question is: why use Android and not another OS as base for these consoles? I assume that there are pragmatic answers to this but I can't see any clear killer feature. For example, one can assume that any stable Linux distribution would work (like Valve seem to think). Android is primarily targetted at mobile platforms which mean it is built around the idea of being interrupted which goes against a lot of what console devs needs in new hardware - but is not killing Android as a platform for gamedev either as it's just a constraint. Why not another OS? What's the Android killer features that make micro-console builder using it instead of Linux or anything else?

• What made you contribute to that open source project? [closed]

  - by Ermin

  I'm interested in real experience and personal answers not just those standard worn out "benefits of contributing to open source" that we all memorized by heart by now. I've met many people who contribute to open source project and almost never did this topic come up: why did they contribute to this open source project. So, if you've contributed to an open source project before in any way, can you please pause for a second and try to remember what really made you decide to contribute to that particular project. Was it a random decision, was it because you were bored, was it because the company you worked for was already using it and you contributed as part of your job, was it because the project was too big you wanted to get contracts, or the project was too small you wanted to build it, or because your prof or co-worker asked you to help with his open source project, or..... To substantiate your reasons, please mention the project name and rate your involvement (heavy, occasional, light, once).

• Good interview programming projects

  - by bigtang

  I'm looking for some small programming projects that I can give potential employees to gauge their programming abilities. These will be programmers straight out of college. I'm looking for projects that would take someone a couple of hours and they would email back their answers post-interview. One example would be to take this paragraph of text and return a list of alphabetized unique words. After each word tell me how many times the word appeared and in what sentance(s) the word appreared in. Anyone have any good suggestions?

• Is C++ really a bad language for beginners? [duplicate]

  - by Chris

  This question already has an answer here: Is C++ suitable as a first language? 24 answers I'm learning C++ right now, and it's the first language I'm learning. I keep seeing on stackexchange and other forums (Reddit, etc.) that I should drop C++ and learn a higher level language like Python or Java. The only arguments I see are that "C++ is harder to learn and is more low-level than others." which don't really give a reason NOT to learn it. I want to know if there are any actual reasons for dropping C++ and taking up another, "easier" language. Or if I should keep focusing on it, and just learn others later (which is what I plan on doing).

• windows system (bootloader) partition accidently deleted during multiple installs

  - by S.Y.T.

  After experimenting with multiple variations of backtrack and xbmcbuntu variations of Ubuntu with dual boot successfully, my windows partition became unrecognizable to grub. I used my windows boot CD to try to correct the problem. However, I deleted all partitions except for the NFTS one that contains my old windows install. (And, merged all other ones into that in hopes of getting back to the windows boot loader and out of grub) Now, all I get is a grub command prompt when I try and boot the system (how??? - I thought I deleted grub) And, now the windows boot disc doesn't even recognize the install. I've tried TRK to try and resolve the problem. Though I must admit ignorance in correctly using this utility. I've searched for other answers to this problem. Any help would be much appreciated. S.Y.

• Visitor-pattern vs inheritance for rendering

  - by akaltar

  I have a game engine that currently uses inheritance to provide a generic interface to do rendering: class renderable { public: void render(); }; Each class calls the gl_* functions itself, this makes the code hard to optimize and hard to implement something like setting the quality of rendering: class sphere : public renderable { public: void render() { glDrawElements(...); } }; I was thinking about implementing a system where I would create a Renderer class that would render my objects: class sphere { void render( renderer* r ) { r->renderme( *this ); } }; class renderer { renderme( sphere& sphere ) { // magically get render resources here // magically render a sphere here } }; My main problem is where should I store the VBOs and where should I Create them when using this method? Should I even use this approach or stick to the current one, perhaps something else? PS: I already asked this question on SO but got no proper answers.

• https (SSL) instead of http

  - by user1332729

  I am building myself a new website, out of privacy and security concerns I am contemplating trying to make it https only. It will be mobile-friendly using media queries but I am concerned--especially for mobile users--about the increased bandwidth. How much will doing so increase my bandwidth or slow load times? For pages where I'm not transferring sensitive information, should I leave external links (to a jQuery library, or a web font for instance) in http? Simply put, I have read articles saying the entire web would be more secure if everything was SSL but my actual knowledge of implementation is limited to payment gateways and log-in pages and such. I apologize for the open-ended nature of the question but anything, even just simple answers to the specific questions is welcomed.

• How to configure Google sitemap links in Wordpress? (without editing its HTML or PHP source code) [duplicate]

  - by Alexander Farber

  This question already has an answer here: What are the most important things I need to do to encourage Google Sitelinks? 5 answers I run a Wordpress 3.7.1–de_DE site, but don't have much experience with it yet. When my site comes up in a Google search, there are 2 links displayed underneath: I believe these links are called "Google sitemap" and my question is how to configure them in Wordpress. Because while the right link is pointing to the /ueber-mich URL at the website, the left link was pointing to an non-existing /imprint and I had to add that webpage as a workaround for now. And I'd like to change the /imprint to German /impressum anyway (currently I use mod_rewrite to redirect). UPDATE: Dear downvoters and movers, would you mind to READ my question please? My question has been about how to configure Google sitemap links in Wordpress. So it is NOT A DUPLICATE (I do not want to edit the HTML code, I want to find the correct configuration in Wordexpress) and my question SHOULDN'T HAVE BEEN MOVED AWAY from wordexpress.stackexchange.com.

• Building an instance system.

  - by Kyle C

  I am looking into how to design an instance system for the game I am working on. I have always wondered how these are created in games like World of Warcraft, where instances == dungeons/raids/etc). Areas that are separated from players other than those in your group, but have specific logic to them. Specifically how can you reuse your existing code base and not have a bunch of checks everywhere ? if (isInstance) do x; else do y; I don't know if this will make too much of a difference on any answers, but we're using a pretty classic "Object as pure aggregation" component system for our entities.

• Android Dynamic 2D Map

  - by Deltharis

  My problem is, I want to create a 2D tiled map. Yes, I know it's been asked a lot. I've seen answers that propose the use of tiled however it only allows (or so it seems to me) to generate static maps that do not change once generated. And I need a large empty uniform space of empty tiles, upon which players may place various buildings (some spanning more than one tile and logically being the same one). How to approach this in Android? Do I make some kind of TableLayout, use arbitrarly large amount of rows and imageviews (with my emptyTile), than somehow work event-based changing of image ids from there? I'd think that only a portion of that map should be visible at a time, but I don't see how scrolling around could be the part of that structure.

• What is the concept behind writing a cancel operation in c++?

  - by ToMan

  I'm attempting to write a cancel operation for a software download application. This application will first transfer the software to the device and then install the software on it. (These are givens I'm not allowed to change). What should the cancel operation do? When a user presses 'cancel', the application should stop transferring/installing the software immediately. Question: Since I've never written a "cancel" function, I'm wondering what are the types of things to consider when writing the code, and what are the common bugs I should expect and how to deal with them? Couldn't find anything in google so if you have some links that would be good reads I'd really appreciate it since I'm not looking for answers I'm just looking for guidelines/macro/concept help
