  • How to use music in a simple game?

    - by Aerovistae
    It's like this: I've got this very simple game in mind, and I happen to be lucky enough to know this guy at my college who is the best musician I've ever met in person who wasn't already on a stage. He writes these beautiful songs on piano, just meandering and mysterious. They'd add so much as background music. But here's my dilemma: say I record a 5 minute long song from him. How do I use it? Do I set it playing, and then make it start over as soon as it ends? Do I leave a 5 minute period of silence and then start it over again? Or do I find other music and just have continuous music playing? What do other people usually do for this sort of thing?

  • web services, J2EE, spring, DB integration project ideas- maybe data mining related?

    - by sj88
    Hey guys, I am a graduate CS student (Data mining and machine learning) and have a good exposure to core JAVA (3 years). I have read up a bunch of stuff on Design patterns J2EE Web services( soap and rest) spring and hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff (over my free time of corse) to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + svn, maven). Any good project ideas would be really appreciated. I just wanna build this stuff to learn so I dont really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus (fits with my research) but absolutly not necesary (since this project is more to learn to do large scale software developement)

  • Dashboard to aggregate Google Analytics, Facebook, YouTube etc tracking data?

    - by Richard
    I'd like to see as much tracking data as possible about my online presence, in one single dashboard - so views/conversions from Google Analytics data, the performance of my Facebook campaigns via the Insights API, views/clicks from my YouTube campaigns, etc. This could be as simple as a graph with time on the x-axis, and key indicators from each source on the y-axis (conversions from Analytics, likes on Facebook, views on YouTube, etc). The idea is that I can see customer engagement with each source, over time. I can write my own such dashboard easily enough, but I wondered if there was something off-the-shelf that already did this. Apologies if this isn't the right forum for such a question - would appreciate tips for the best place to ask.

  • What file manager/uploader do you use with your embeded wysiwyg editor ?

    - by Wookai
    I am looking for a wysiwyg editor to allow user to edit part of their website. I already worked with TinyMCE, and heard about CKEditor, which both look great. However, they both lack a free (PHP) file manager/uploader, as they sell their own tool to make some money. I found a few free alternatives for TinyMCE, the best one (for my needs) being PHP Letter's one, but I was wondering about what the community uses ? Do you buy the "official" file manager ? Do you code your own ? Or do you have a great (free) alternative ?

  • Designing exceptions for conversion failures

    - by Mr.C64
    Suppose there are some methods to convert from "X" to "Y" and vice versa; the conversion may fail in some cases, and exceptions are used to signal conversion errors in those cases. Which would be the best option for defining exception classes in this context? A single XYConversionException class, with an attribute (e.g. an enum) specifying the direction of the conversion (e.g. ConversionFromXToY, ConversionFromYToX). A XYConversionException class, with two derived classes ConversionFromXToYException and ConversionFromYToXException. ConversionFromXToYException and ConversionFromYToXException classes without a common base class.

  • How To Run Chrome OS From a USB Drive and Use It On Any Computer

    - by Chris Hoffman
    Google only supports running Chrome OS on Chromebooks, but don’t let that stop you. You can put Chrome OS on a USB drive and boot it on any computer, just as you’d run a Linux distribution from a USB drive. If you just want to test Chrome OS, your best bet is running it in a virtual machine. This ensures that you won’t run into any hardware-related issues. Your computer may not be able to run Chrome OS properly. Note: You’ll need a USB drive with at least 4 GB of space for this. 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

  • Is acoustic fingerprinting too broad for one audio file only?

    - by IBG
    We were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acoustic fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

  • "Super meatboy"-ish replay

    - by Ron
    I'm making a platformer built from mini-levels - and I want to create a sort of a replay of all the player tries that the player did for the level. My question is - what is the best way to record the player's actions in-game, so that I could replay them later when he finishes the level. I thought about recording only the player's input and replay them later on, each on a clone of the player. The problem I have with this is with dynamic obstacles (that could be moved around) - if one clone moves them, it throws the simulation off for the rest of the clones. So then I thought about recording every frame the X/Y of the player, and then just replay it - but that seems it could cause a major memory leak and very ineffective. So - does anyone have any ideas? :)

  • What are the dos and dont's when leaving a job? [closed]

    - by john ryan
    I'm going to resign from my current employer (manufacturing sector), where I've been working for 2.6 years as an IT Application Developer. It's the first company I've worked in after I graduated from college. I don't have any problem with the company, I just realized that I want to learn new technologies and get out of my comfort zone and move to the IT industry. I already got a job offer from another company. My IT manager has told me that I am one of the best players in our group, that our group is enough to support our company and that it would be unacceptable if anyone of us resigned. They will counter the offer, but I'm set on leaving. My problem is that I don't know what are the essential dos and don'ts when resigning from a current employer. For example I'm expecting a lot of inquiries on why I'm leaving from people in the company, what do I need to say?

  • Matching my skills with Java and Web Programming

    - by John R
    here is my main question: What is the most common way that Java is used in web development? The reason I ask: I am currently in the process of finding my first internship. Every employer has a separate set of languages, technologies and acronyms they want their candidates to know. In school I did well with Java. As a hobby and interest I have developed a handful of web pages widgets, scripts, etc. My university emphasized Java, C and theory. My hobbies emphasize HTML, PHP, JavaScript, CSS, and a little jQuery, etc. I can't learn a dozen different technologies to satisfy most prospective employers (in what is left of the summer). I think my best bet is combine my skills with Java and my interests in web development. That brings me back to my original question: What is the most common way that Java is used in web development?

  • Why is cleverness considered harmful in programming by some people?

    - by Larry Coleman
    I've noticed a lot of questions lately relating to different abstraction techniques, and answers saying basically that the techniques in question are "too clever." I would think that part of our jobs as programmers is to determine the best solutions to the problems we are given to solve, and cleverness is helpful in doing that. So my question is: are the people who think certain abstraction techniques are too clever opposed to cleverness per se, or is there some other reason for the objection? EDIT: This parser combinator is an example of what I would consider to be clever code. I downloaded this and looked it over for about half an hour. Then I stepped through the macro expansion on paper and saw the light. Now that I understand it, it seems much more elegant than the Haskell parser combinator.

  • Lubuntu 14.04 graphics problem on portege r100

    - by user286069
    first of all I have to say that I am not an expert. I have installed Lubuntu 14.04 on my Portege R100. The problem is that the graphics session does not start. Actually I can do all but only by command line. I try to start Xsession but nothing happens. Actually by typing startx the system stop to works. I read several threads on this topic but I did not find such kind of problem. There is something similar about portege r100 concerning lowgraphics mode but the porblem I have seems to be different because graphics session does not start. Can anyone help me ? Thank you Best

  • Develop open-source library and get donations for it?

    - by Robottinosino
    I have a nice open-source library in mind to write. It would take a few months to develop properly and I would need to stop supporting myself though other projects. Could anybody share experiences and best-known-methods to get some sort of financial support through the Internet whilst developing free, open-source code? Or, phrased more directly: which systems apart from "PayPal" are in use by programmers to get donations for open-source code? Provide a list. Optionally, sort the list as if it were a recommendation in descending order of positive experiences made with each system. Optionally, share a tidbit of your success story getting this kind of financial support. Optionally: give an indication as to how much money can be made that way? (I heard Vim's author could support himself just with donations at some point?)

  • Kill Android Apps without Task Manager

    - by Gopinath
    Android is for geeks. It best fits for the users who know how to get around sloppy areas and find their way out. If you are an heavy Android user you would have noticed Apps crashing often. A well written App should not crash, if crashes should exit the process gracefully. But unfortunately Google Play has many apps that not only just crash, they hang in a where they don’t respond and you can’t access the application. The only option left to you is to forcefully close them. If you encounter a situation to forcefully close an App you have two options. First one is to use Task Manager application to close them and the second option is use built in Android OS features. Here are the steps to forcefully close an Android App without using Task Manager Step 1: Go to Settings and select Apps Step 2: Switch to All apps tab and select the application you want to close Step 3: Touch on Force Stop button to forcefully close the app That’s the simplest way to forcefully kill Android Apps.

  • Converting large files in python

    - by Cenoc
    I have a few files that are ~64GB in size that I think I would like to convert to hdf5 format. I was wondering what the best approach for doing so would be? Reading line-by-line seems to take more than 4 hours, so I was thinking of using multiprocessing in sequence, but was hoping for some direction on what would be the most efficient way without resorting to hadoop. Any help would be very much appreciated. (and thank you in advance) EDIT: Right now I'm just doing a for line in fd: approach. After that right now I just check to make sure I'm picking out the right sort of data, which is very short; I'm not writing anywhere, and it's taking around 4 hours to complete with that. I can't read blocks of data because the blocks in this weird file format I'm reading are not standard, it switches between three different sizes... and you can only tell which by reading the first few characters of the block.

  • Does Agile (scrum) require one server environment?

    - by Matt W
    Is it necessary/recommend/best practice/any other positive to use only one server environment to perform all development, unit testing and QA? If so, is it then wise/part of Agile to then have only one staging environment before Live? Considering that this could mean internationally distributed teams of developers and testers in different time zones is this wise? This is something being implemented by our QA manager. The opinion put forward is that doing all the dev and testing on a single server is "Agile." The staging environment would be a second environment, and then live.

  • Using branches for a mini project or module of project: Good practice?

    - by TheLQ
    In my repo I have 3 closely related mini projects: 1 server and 2 clients. They are all quite small (<3 files each). Since they are so small and so closely related I just dropped them in folders in one single repo. However now that I know I can't clone a single directory in my VCS of choice (Mercurial), I'm considering splitting them up. However I'm confused about general best practice: Is it okay to put different small projects in different branches, or should they all go in different repos? I'm currently leaning towards branching since I can't easily splice out the file history of the different projects but then your using a feature in a way it wasn't meant to be used.

  • How to avoid circular dependencies between Player and World?

    - by futlib
    I'm working on a 2D game where you can move up, down, left and right. I have essentially two game logic objects: Player: Has a position relative to the world World: Draws the map and the player So far, World depends on Player (i.e. has a reference to it), needing its position to figure out where to draw the player character, and which portion of the map to draw. Now I want to add collision detection to make it impossible for the player to move through walls. The simplest way I can think of is to have the Player ask the World if the intended movement is possible. But that would introduce a circular dependency between Player and World (i.e. each holds a reference to the other), which seems worth avoiding. The only way I came up with is to have the World move the Player, but I find that somewhat unintuitive. What is my best option? Or is avoiding a circular dependency not worth it?

  • Will adding q&a help my site's rankings, and if so, what are the implications of a sub-domain for q&a rather than a path on the site? [closed]

    - by ElHaix
    Possible Duplicate: Subdomain versus subdirectory One of our web properties is doing quite well without any additional links being created on the site, and our link inventory is tightly managed - no user-generated links. To introduce a community aspect to the site, we want to implement a q&a forum. Once in place, new links will populate our link inventory with keywords that are not necessarily targeted to the site. With the q&a on a sub-domain, would that not affect the main site's rankings? What's the best approach for this?
