• I'm looking for websites with programming problems that I can practice [on hold]

  - by Spentak

  I want to become a more skilled programmer. I also want to do it through Objective-C and iOS. What websites or programs that you know of have problems that I can solve (with the answers)? I have failed some programming tests for jobs (such as "Given 2 values in a Binary Tree - how do you find the lowest common ancestor?) and I want to become a better engineer. I have developed 54 iOS/Android apps to date, but my core CS Skills apparently are rusty/bad. I have looked at TopCoder - but there aren't very many competitions going on, the website is terrible, and there does not appear to be anything that really supports Objective-C/iOS Websites?

• How to transfer domain from Godaddy to another provider

  - by licorna

  I'm currently using godaddy for all of my company domains, and I'm very unsatisfied with their service, specially with their site, so we are trying to migrate those domains to another provider. The question is, How do I transfer my domains to another domain registrar? I'm not talking about transferring domain records (A, MX...) but to use the same domains with another provider, and redo all the configuration again. For example, one of our blogs is hosted in Slicehost and we feel very confortable with their record editing tool. As I have read prowebmasters I can see other people not very satisfied with Godaddy service. Thanks! edit: Thanks for the answers, they were all very informative.

• Why dd is not a reliable command to write bootable .iso files to USB thumb drive?

  - by Samik

  As the answers here indicate Ubuntu .iso s are not expected to boot if copied with dd to a USB thumb drive. Now my question is why is so that some Linux distributions have the option to directly write their bootable .iso file to a thumb drive with dd but some (read Ubuntu) have not(for Ubuntu I think it has to be converted to .img first). Is it for some architectural difference in .isos? Or is it due to any limitation of dd itself?I don't know if it is off-topic here. I can move it to a more proper place if the community thinks so or suggests one. Some explanation would be appreciable.

• YUI and/or jQuery for a new project?

  - by Hortitude

  If I am starting a new project how should I pick between using YUI 2, YUI 3 and jQuery? I know there are a bunch of questions/answers already about can you use them together, but I am trying to figure out what criteria I should be thinking about to make my decision. Are they overlapping? Is one better at GUI and the other better at internals? Do they play well together? My understanding from other questions is that they can live in different namespaces, so they can live together, but that doesn't necessarily mean that it is good to use both. Thanks!

• Soccer Game only with National Team names (country names) what about player names? [duplicate]

  - by nightkarnation

  This question already has an answer here: Legal issues around using real players names and team emblems in an open source game 2 answers Ok...this question hasn't been asked before, its very similar to some, but here's the difference: I am making a soccer/football simulator game, that only has national teams (with no official logos) just the country names and flags. Now, my doubt is the following...can I use real player names (that play or played on that national team?) From what I understand if I use a player name linked to a club like Barcelona FC (not a national team) I need the right from the club and the association that club is linked to, right? But If I am only linking the name just to a country...I might just need the permission of the actual player (that I am using his name) and not any other associations, correct? Thanks a lot in advance! Cheers, Diego.

• 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.

• 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).

• 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).

• 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?

• 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.

• 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?

• Creating a templated silverlight control that has a story board.

  - by Mrt

  I'm trying to create a templated silverlight control that has a simple animation (swap a few color properties). An example would be a control that is similar to the 'questions' menu item in stackoverflow. So the consumer of the control can specify the background color and the background color for the mouseover event. I've run into the issue that I can't use template binding for a storyboard animation (http://stackoverflow.com/questions/1336689/is-it-possible-to-use-templatebinding-in-a-storyboard-in-silverlight). Whats the best work around to this ? Cheers, MrT

• What happened to the this type of naming convention?

  - by Smith

  I have read so many docs about naming conventions, most recommending both Pascal and Camel naming conventions. Well, I agree to this, it's ok. This might not be pleasing to some, but I am just trying to get your opinion on why you name your objects and classes in a certain way. What happened to this type of naming conventions, and/or why are they bad? I want to name a structure, and I prefix it with "struct". My reason is that, with IntelliSense, I see all structures in one place, and anywhere I see the struct prefix, I know it's a "struct": structPerson structPosition another example is the enum, although I may not prefix it with "enum", but maybe with "enm": enmFruits enmSex again my reason is that in IntelliSense, I see all my enumerations in one place. Because .NET has so many built-in data structures, I think this helps me do less searching. Note that I used .NET in this example, but I welcome language agnostic answers.

• 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.

• 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.

• 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.

• How do you share pre-calculated data between calls to a Rails web service?

  - by Nigel Thorne

  I have a Rails app that allows users to build up a network structure and then ask questions about how to navigate around it. When adding nodes and connections these are just saved to the database. At the point you make a query of the network I calculate the shortest path from any node to any other node. Constructing this in memory takes a while (something I need to fix), but once it is there, you can instantly get the answer to any of these path questions. The question is... How do I share this network between calls to the website, so each request doesn't regenerate the paths network each time? Note: I am hosting this on apache server using passenger (mod ruby) Thoughts?

• 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.
