• how to properly credit authors of MIT license program

  - by kon psych

  Although I have found similar questions on this site they were not what I was looking for. I have modified the source code of an MIT licensed project, and I have added new classes to it as well. Please correct me if I am wrong, but I think that it is legal to add my copyright notice above the license and remove the other one. But how should I attribute the contribution of the previous authors? Should I use a separate file? There are also some html files with no license or copyright notice in them which I also modified. Do I have to handle them differently? My question is different than this question in that I have also modified some of the files of the project I am extending.

• How can I find a good open source project to join?

  - by Lord Torgamus

  I just started working a year ago, and I want to join an open source project for the same reasons as anyone else: help create something useful and develop my skills further. My problem is, I don't know how to find a project where I'll fit in. How can I find a beginner-friendly project? What attributes should I be searching for? What are warning signs that a project might not be the right fit? Are there any tools out there to help match people with open source projects? There's a similar question here, but that question has to do with employment and is limited to PHP/Drupal.

• adding mongo to path

  - by Mike

  Bit of a noob question. I have downloaded MongoDb and installed it here /Users/mike/downloads/mongodb In order to start it, I then have to 'cd' into the 'bin' /Users/mike/downloads/mongodb/bin and run ./mongod (to start the database) and ./mongo (to start the mongo shell) The problem is that I can only work with python and ruby scripts using the mongo shell if I have those scripts stored in the same bin directory, and I don't think that's the ideal set up. Will exporting the path allow me to access mongo from outside the bin? For example, I would prefer to have my ruby scripts in /sites/ruby and be able to access mongo by starting ruby in /sites/ruby. If exporting to path is the solution, how do I do that. I'm using a mac

• How do I let programmers know something useful?

  - by Shane

  Quite often I go through pain to discover how to do something useful, in this case how to get PHP running on Google App Engine without the 'resin.jar too big' problem, but I have nowhere to let people know. In this particular case, the web answers were incomplete, outdated or plain wrong. I could create a blog, but it's overkill. I just want let programmers know a quick solution/approach. I'm not sure it's the done thing to ask a question and then answer it. In short, it'd be nice to be able to just dump a sort of combined question/answer/snippet, then let others comment as usual, shoot it down, like it, whatever. How do the rest of you approach this? Cheers, Shane

• Making an interface for input in C - How?

  - by tloszk

  I have a big question. I started to develop a simple 3D engine (or should I call it framework?). I use OpenGL for rendering and it is developed for Windows. It is all written in C. But I don't know, how to write an "interface" for the keyboard/mouse input. I would like to keep it as simple as possible and nice - what the Win32 "native" input system is not. If anyone has suggestions about the topic, please, tell me. Thanks for everyone, who answers to my question!

• Collision Detection and Resolution in Three.js

  - by androidmaster

  So at the moment am making a simple game using three.js and three.firstpersonControls.js but with the current Three.js r66, they apparently removed checkWallCollision and then in the r67 firstpersonControls removed support for that collision. SO my question is how would i go about checking collision in 3D using three.js and then resolution to that collision. (Pushing player out of the block) Note I used a 2D array to generate the world so it's only cubes that I have to check collision with.... if this is a bad question or am lacking something please tell me before you -rep me, am just not sure how to do this and google doesn't want to help

• Job Interview at Starbucks for Programmers [closed]

  - by Soner Gönül

  My friend is called for a job interviewing at Starbucks a few days ago. IMHO, but these kind of places a not very suitable environment for interviewing specialy for programmers. Actually, my question has 2 sides; Side of Interviewers: If you are interviewing at starbucks with a candidate as an Interviewer, How candidate should act there you prefer? What he/she should do or not? What would you pay attention on his/her? Side of Candidate: How you should act instead of interviewing in a meeting room? Should you drink something or not (if Interviewer ask)? Should you ask a question like "Why am I interviewing in this place?" What is the advantages and disadvantages of an interviewing by programmers in this kind of places?

• Ubuntu, Gnome, PAM and ecryptfs

  - by Michel

  I would like to have a directory accessible to a couple of users, and not readable by maintenance types ... I can do what I want using ecryptfs and a password known only to the "couple of users" in question, who then can mount the directory and use as they see fit. I would love to be able to automate that process and unlock the directory at login - again, only for the "couple users" in question, without asking a password. Gnome-keyring is able to store passphrases/passwords encrypted; and, apparently, if I could get a key identity to ecryptfs, Gnome PAM modules would allow the key with that identity to be unlocked, and the directory could be mounted. Alas, I have found no way to go from point A (Gnome PAM keyring module) to point B (use the unlocked key in ecryptfs). Another use of the same mechanism would allow to build a "key escrow" mechanism, where keys to encrypted volumes are safekept with, e.g., HR; so that company information in encrypted directories can be recovered if you pass under the proverbial bus.

• Page rank lost on subpage

  - by Niko Nik

  I have one question for PageRank. Maybe someone has an idea: I have this site: http://bit.ly/MyjVjA . 3 Days ago I had here PR5 and here were keywords as well. 3 days ago I have changed the site and set new keywords. Today I have loose the PR. The question is, why? I know other pages like this: bit.ly/Myk9qG or bit.ly/KtT2u1 and they have the same situation like me, with many keywords, but they have still PageRank. Is this because I have change the content of the site, or is there something, what I have made wrong to loose the good PR I had. How can I become it again? Thanks for all ideas! Best Regards Nik

• How to UEFI install Ubuntu 12.10?

  - by Geezanansa

  Running a newer FM1 motherboard which is using an AMD 3870k APU with a new 1TB HDD. Following the advice in the motherboard manual and https://help.ubuntu.com/community/UEFI have now got to grub option screen for UEFI install. see http://imgur.com/VW5vz The dvd.iso being used is Ubuntu 12.10 desktop amd64 from ubuntu .com. The hdd has had a gpt partition table made for, by using gparted when in a live desktop session when booted in bios mode. (*edit/update: Although the old cd updates on running it is an old kernel and it did make a gpt but that version of gparted uses fdisk whereas gdisk is required to make gpt. Think am going to have to spend more time here http://www.dedoimedo.com/computers/gparted.html lol Using the gparted from 12.10 live session to make partitions; following the guidance regarding this at https://help.ubuntu.com/community/UEFI#Creating_an_EFI_partition, but can only boot to grub option screen http://imgur.com/VW5vz when 12.10 options to "try ubuntu" or "install ubuntu" are selected they give errors as described below*) but after making the gpt decided to leave it unformatted/unallocated space with the intention of using installer to set up partitions. update-originally but gparted now sees hdd as http://imgur.com/hFIvm as described above. *Booting live dvd in EFI mode gives "Secure Boot not installed" just before grub kernel option list with the option to "install ubuntu" but get "can not read cd/0" and "the kernel must be loaded first" errors; when that option is selected. Any pointers on how to get installer going for UEFI install would be good. Thanks in advance. update: Hopefully these screenshots can help better highlight where i am going wrong or if there is something else going on http://imgur.com/g30RB, http://imgur.com/VW5vz, http://imgur.com/31E0q, http://imgur.com/bnuaG, http://imgur.com/y4KGu, http://imgur.com/3u2QE, http://imgur.com/n9lN3, http://imgur.com/FEKvz, http://imgur.com/hFIvm, update: Thank you fernando garcia for pointing me in the right direction to start the process of elimantion. What i have done since asking question is a little home work starting here http://askubuntu.com/faq#bounty and here http://askubuntu.com/questions/how-to-ask. Looking at other similar questions was good fun and found this 12.10 UEFI Secure Boot install the most relative in helping getting ubuntu to uefi install on my system. In response to wolverine's question this article was referred to http://web.dodds.net/~vorlon/wiki/blog/SecureBoot_in_Ubuntu_12.10/ This article in the first sentence gives a link to http://www.ubuntu.com/download which is where i downloaded the 12.10 desktop amd64 .iso(and others) but have been unable to do a efi install of ubuntu on this system and as this is a new system have ended up just going with bios installer running which at least puts my mind at ease that i have not bricked my new mobo.(had to do a clrcmos and flash to latest bios version) So it possibly could be the bios settings or the bios version being used that is problem. To try and eliminate bios version i can not get to post screen in order to id bios version being used. Pressing tab to show post instead of logo and trying to pausebreak to catch post is proving difficult. If logo screen in bios is disabled just get black screen no post shown and pressing tab does not show post. Appreciate using appropriate bios settings and latest 12.10 release should simply get uefi installer running when selected from the grub list (nice graphic details in Identifying if computer boots the cd in efi mode section at https://help.ubuntu.com/community/UEFI#Identifying_if_the_computer_boots_the_CD_in_EFI_mode) And to confirm the hdd is booting in efi mode https://help.ubuntu.com/community/UEFI#Identifying_if_the_computer_boots_the_HDD_in_EFI_mode running the command [ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD" gave Legacy boot on HDD This is as expected because i allowed the bios installer (which was 12.04 desktop amd64 after trying 12.10 desktop amd64 in efi mode) to run to get a working installation. Which is not what was intended or wished for but wanted to get a working os to bench test new mobo i.e. prove it is working. There are other options as in installing other bootmanagers/loaders but do not wish to do so as shim should get grub2 going that is after secure boot has been signed.(Now got rough idea what should happen just it aint happening. Is it possible ahci drivers are required?) Will post boot info script url of the updated config/setup. The original question asked seems irrelevant to what is being said in this update but as the problem is not resolved will keep on trying efi installing! i.e the problem is same as when question asked just trying to update. Have tried to edit and update the best i can!

• Is there a viable alternative to the agile development methodology? [closed]

  - by Eric Wilson

  The two predominant software-development methodologies are waterfall and agile. When discussing these two, there is often much focus on the particular practices that distinguish them (pair programming, TDD, etc. vs. functional spec, big up-front design, etc.) But the real differences are far deeper, in that these practices come from a philosophy. Waterfall says: Change is costly, so it should be minimized. Agile says: Change is inevitable, so make change cheap. My question is, regardless of what you think of TDD or functional specs, is the waterfall development methodology really viable? Does anyone really think that minimizing change in software is a viable option for those that desire to deliver valuable software? Or is the question really about what sort of practices work best in our situations to manage the inevitable change?

• Tips on googling for sugar

  - by Mikey

  I have a question up on SO I am a little embarassed I can't just google: http://stackoverflow.com/questions/13734664/groovy-variables-in-method-names-with-double-question-marks The problem is google seems to chuck any terms that are just punctuation, so queries like these: .findBy?? .and?? groovy '??' Are coming out the same as these: findBy and groovy I have had this problem before when I didn't know the name of the elvis operator, and countless other times (probably happened first time I saw an infix '%' mod too if I had to guess). Is there a resource for syntax sugar lookups? Some way to force google or a different search engine to not ignore my funky punctuation?

• deploying a Python application from a PHP developer

  - by user1218776

  I'm a little confused on the deployment process for Python. Let's say you create a brand new project with virtualenv source bin/activate pip install a few libraries write a simple hello world app pip freeze the dependencies When I deploy this code into a machine, do I need first make sure the machine is sourced before installing dependencies? I don't mean to sound like a total noob but in the PHP world, I don't have to worry about this because it's already part of the project. All the dependencies are registered with the autoloader in place. The steps would be: rsync the files (or any other method) source bin/activate pip install the dependencies from the pip freeze output file It feels awkward, or just wrong and very error prone. What are the correct steps to make? I've searched around but it seems many tutorials/articles make an assumption that anyone reading the article has past python experience (imo).

• Game-oriented programming language features/objectives/paradigm?

  - by Klaim

  What are the features and language objectives (general problems to solves) or paradigms that a fictive programming language targetted at games (any kind of game) would require? For example, obviously we would have at least Performance (in speed and memory) (because a lot of games simply require that), but it have a price in the languages we currently use. Expressivity might be a common feature that is required for all languages. I guess some concepts from not-usually-used-for-games paradigms, like actor-based languages, or language-based message passing, might be useful too. So I ask you what would be ideal for games. (maybe one day someone will take those answers and build a language over it? :D ) Please set 1 feature/objective/paradigm per answer. Note: maybe that question don't make sense to you. In this case please explain why in an answer. It's a good thing to have answers to this question that might pop in your head sometimes.

• What technologies are used for Game development now days?

  - by Monika Michael

  Whenever I ask a question about game development in an online forum I always get suggestions like learning line drawing algorithms, bit level image manipulation and video decompression etc. However looking at games like God of War 3, I find it hard to believe that these games could be developed using such low level techniques. The sheer awesomeness of such games defy any comprehensible(for me) programming methodology. Besides the gaming hardware is really a monster now days. So it stands to reason that the developers would work at a higher level of abstraction. What is the latest development methodology in the gaming industry? How is it that a team of 30-35 developers (of which most is management and marketing fluff) able to make such mind boggling games? If the question seems too general could you explain the architecture of God of War 3? Or how you would go about producing a clone? That I think should be objectively answerable.

• Is Google Closure a true compiler?

  - by James Allardice

  This question is inspired by the debate in the comments on this Stack Overflow question. The Google Closure Compiler documentation states the following (emphasis added): The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. However, Wikipedia gives the following definition of a "compiler": A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language... A language rewriter is usually a program that translates the form of expressions without a change of language. Based on that, I would say that Google Closure is not a compiler. But the fact that Google explicitly state that it is in fact a "true compiler" makes me wonder if there's more to it. Is Google Closure really a JavaScript compiler?

• What are some valuable conferences for game developers?

  - by Tommy

  Lately I was thinking of visiting a Game Developer Conference and so I search the Internet, but I didn't find a thorough list of available Conferences. Now I know some of them, like the GDC in San Francisco but I was wondering, what other Game Developer Conferences are out there. So my question is: What Game Dev Conferences do you know, that are valuable for Game Developers and Game Designers? Have you visited one of these Conferences yourself? Is there a skill level needed to appreciate such a Conference? I am aware, that there is no "true" answer to this question, but I think, that an overview over existing Conferences could be usefull for all levels of game developers.

• Google webmaster tools: parameters that only apply on one page

  - by Imagine digital

  I'm trying to get my e-commerce website on google and still figuring out how it all works. Now, I have seen this feature named URL-parameters, allowing me to set different parameters that affect page content to be indexed (one can also set parameters that do not affect the page, but for me that does not apply..). The question I have about this is whether and how I should add parameters that I only have on some pages of my site. example: The homepage of my site is www.mysite.nl. no parameters at all. But when a user clicks the navigation bar, it links to www.mysite.nl/itemList.php?category=&....subCategory=.... The parameters category and subCategory define whether there is content on my itemList page and what content that is. It gets matching products out of my database based on those 2 variables. The question: How do I make sure that I apply the google URL Parameters function decently for my website?

• Adding a Wine (.exe) file to open/play files in Thunar's 'Custom Actions'

  - by cipricus

  What is the line parameter in Thunar's "custom actions" that would play a music directory in a Wine (.exe) program? I want to put Foobar2000 (and possibly other such applications) in Thunar's Custom Actions (actions that can be added/edited to be used in the context menu to play music folder's content). If I put no command parameter at the end of path, the player opens but there is no play and no files in the play list. If I add any of the listed parameters I get the error unknown commandline parameter: /path.to.file (Giving an answer to this question depends on knowing the CLI command that would have to be added into Thunar - so please look at this question too)

• Linking Libraries in iOS?

  - by Joey Green

  This is probably a totally noob question but I have missing links in my mind when thinking about linking libraries in iOS. I usually just add a new library that's been cross compiled and set the build and linker paths without really know what I'm doing. I'm hoping someone can help me fill in some gaps. Let's take the OpenCV library for instance. I have this totally working btw because of a really well written tutorial( http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en ), but I'm just wanting to know what is exactly going on. What I'm thinking is happening is that when I build OpenCV for iOS is that your creating object code that gets placed in the .a files. This object code is just the implementation files( .m ) compiled. One reason you would want to do this is to make it hard to see the source code and so that you don't have to compile that source code every time. The .h files won't be put in the library ( .a ). You include the .h in your source files and these header files communicate with the object code library ( .a ) in some way. You also have to include the header files for your library in the Build Path and the Library itself in the Linker Path. So, is the way I view linking libraries correct? If , not can someone correct me on this ?

• Collision Detection Game Design and Architecture

  - by Chompas

  I've reading some articles about collision detection. My question here is about ideas on the design for it. Baically I have a C++ game that has a main loop with entities with an update method. Based on keyboard input, these characters updates their positions. My question is not about how to detect collisions, it's about getting ideas in which is the best way to implement this. The game has a main character but also enemies that have to collide between them, so I'm not sure where to make all the iterations for checking collisions and if the right way is to check everything against everything. Thanks in advance.

• Support same url in different forms

  - by Vikas Gulati

  I have seen many websites supporting multiple forms of the same URL. For example consider www.example.com/question1/ OR www.example.com/Question1/ OR www.example.com/QUESTION1/ etc. all lead to one page with say <link rel="canonical" href="http://www.example.com/question1/" > or a 301 redirect to www.example.com/question1/. Does this affect the page rank anyhow or its just for seemless user experience or there is some other reason behind this? Infact even stackoverflow/stackexchange does this. No matter what the text after the id of the question in url they redirect you to the correct question!

• Are there any negative impact running all services on a single static IP?

  - by Jake

  I need to setup a VPN trunk (with remote branch office location), Video Conference and Web Server on-premise in the office. I am used to ISP providing blocks of 8 or 16 IPs. But I have a new ISP which says they only can provide a single IP. Are there any issues with running all services on a single IP? I don't think this has any thing to do with bandwidth..? I'm not using SSL certificates... I can do port forwarding to different machines... What else...? Disclaimer: I am a programmer by training. Sorry for noob question.

• How do I render my own DirectX Stuff to a full screen WPF's DirectX surface?

  - by marc40000

  Basically Danny Varod seems to know as he posted it as an answer to this question: Display a Message Box over a Full Screen DirectX application I think, theoretically this might work, but I have no idea how to actually do it. Since I'm also not allowed to post a comment under his comment nor am I allwoed to ask on meta about how to contact another user, I ask this as a normal question here: How do I render my own DirectX Stuff to a full screen WPF's DirectX surface? For starters, I have no idea how to get the DirectX surface from a WPF window. If I had it, what do I have to take care of that the WPF rendering doesn't screw up my own rending or vice-versa?
