• Question about creating a sprite based 2-D Side Scroller with scaling/zooming

  - by Arthur

  I'm just wondering if anyone can offer any advice on how best to go about creating a 2-D game with zooming/scaling features akin to the early Samurai Showdown games. In this case it would be a side scroller a la Metal Slug, the zooming would come in as more enemy sprites entered the screen, or when facing a large sized boss. A feature that would be both cosmetic as well as functional to the game. I've done some reading and noticed a few suggestions that included drawing different sized sprites, a standard size and zoomed out size. Any thoughts? Thanks for your time.

• Sound no longer changes when I plug in headphones in Ubuntu 12.04

  - by Victor9098

  In ubuntu 11.10 (I am not 100% about 11.04) when I plugged in my headphones the sound settings would automatically set themselves to my preferred setting (on 100% and then use the dial on the headphones to control). Then when I unplugged them the sound would go back to whatever I had been using previously. Since upgrading to 12.04 this has stopped working. Instead I have to adjust my sound settings after I plug in headphones and remember to turn down before unplugging. Does anybody know how to get this working again or has the feature been removed in 12.04?

• Better way to search for text in two columns

  - by David

  Here is the scenario. I am making a custom blogging software for my site. I am implementing a search feature. It's not very sophisticated - basically it just takes the search phrase entered and runs this query: $query="SELECT * FROM `blog` WHERE `title` LIKE '%$q%' OR `post` LIKE '%$q%'"; Which is meant to simply search the title and post body for the phrase entered. Is there a better way to do that, keeping in mind how long it would take to run the query on up to 100 rows, each with a post length of up to 1500 characters? I have considered using a LIMIT statement to (sometimes) restrict the number of rows that the query would examine. Good idea?

• How to build a dynamic grub on a usb-drive?

  - by 13east

  I would like to setup GRUB on a USB where it detects automatically the available OS installations on the machine that it is plugged into. This could be useful if you messed up your default GRUB menu on a computer and would like to boot into the machine w/out booting Live-OS. Or if you have multiple Live-OS installations on a USB-Drive and would like to add/remove different installations w/out needing to update grub manually. I know that Grub2 has a OS-prober feature that looks for other installations on the hard-drive, but will that work in either of the scenarios listed above?

• 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 Track "Similar Product/Page" Links In Internal Site

  - by Petra Barus

  So I just created a new widget that would show up in a product page in my site. This widget will show several products similar to the product that is displayed in the current page. The purpose is to help users compare similar products. Let's say in the product page A http://domain/products/A The Similar Products widget will show http://domain/products/B http://domain/products/C http://domain/products/D http://domain/products/E My question is how to track this "Product B page were visited X times from Product A page via Similar Product widget"? (And there is also chance that Product B will show up in the widget on Product C page) I have this idea using the Event feature from Google Analytics. But I'm still not sure if it is or what is the common best practice for this.

• How to CURL and avoid timeout death (Twitter Down) [migrated]

  - by David

  Twitter is down right now, and one of my site's home pages relies on getting data from Twitter (relies is the problem - it should be more of an accessory feature, as it just shows follow count from its feed). Here's the code in question: function socials_Twitter_GetFollowerCount($username) { $method = function () use ($username) { return file_get_contents('https://api.twitter.com/1/users/show.json?screen_name='.$username.'&include_entities=true'); }; $json = cache('bmdtwitter', 3600, $method, false); $json = json_decode($json, true); return intval($json['followers_count']); } What is a good way to make it so if Twitter is down (or not responsive for some reasonable amount of time), our site doesn't appear to be down (I think the timeout maybe defaulting to 30-60 seconds or more).

• How to disable drag and drop of text within the textarea? [migrated]

  - by Manoj Agarwal

  I am working on UI Design, where I need to use Html textarea object. The sample code is: <textarea rows="5" cols="60" spellcheck="false" style="font-size:12px; font-family: Verdana;"> Abc Xyz Mnp Pqr </textarea> I don't want to disable the textarea, since there are some cross-browser issues. If I point on 'y' in 'xyz' and drag it after text 'Mnp', it will be shifted as 'Mnpyz'. I want to avoid this drag and drop feature of text within the text area.

• How to use Google Analytics as an affiliate to track sales data

  - by lalex

  As an affiliate, how can we get more information on sales? It looks like the goals feature in GA is for those who have control over the receipt page. But we are sending users away using an affiliate link. With event tracking, we've been able to count the clicks and see which links are being clicked the most, but not which ones actually convert. We want to find out the following on each sale: Did the converted user come from search or internal traffic? If it was search, which keyword brought the user to our site (and clicked away and converted)? Is it possible?

• Teaching java interfaces to absolute beginners: What is a good example? [closed]

  - by mrsteve

  Possible Duplicate: Explaining interfaces to beginning programmers? I searched on stackoverflow and here for a good example to teach java interfaces in a beginners class. I found the following post: http://stackoverflow.com/questions/416331/java-interfaces The Official Java-Tutorial and the references feature examples that are quite good but I would need a very simple example to start with for my class. I don't think the offical tutorial is the best resource for absolute beginners. The students are easily confused, and the most effective example would help. Any pointers or experience in teaching java interfaces?

• Is a function plotter a legitimate use of eval() in JavaScript?

  - by moose

  From PHP development I know that eval is evil and I've recently read What constitutes “Proper use” of the javascript Eval feature? and Don't be eval. The only proper use of eval I've read is Ajax. I'm currently developing a visualization tool that lets users see how polynomials can interpolate functions: Example Code on GitHub I use eval for evaluation of arbitrary functions. Is this a legitimate use of eval? How could I get rid of eval? I want the user to be able to execute any function of the following forms: a x^i with a,i in R sin, cos, tan b^x with b in R any combination that you can get by adding (e.g. x^2 + x^3 + sin(x)), multiplying (e.g. sin(x)*x^2) or inserting (e.g. sin(x^2))

• Forked a project, where do my version numbers start?

  - by TheLQ

  I have forked a project and have changed lots of it. This fork isn't just a small feature change here and a buried bug fix there, its a pretty substantial change. Only most of the core code is shared. I forked this project at v2.5.0. For a while I've started versioning my fork at v3.0 . However I'm not sure if this is the right way, mainly because when that project hits v3.0, things get confusing. But I don't want to start over at v1.0 or v0.1 because that implies infancy, instability, and non-refindness of a project. This isn't true, as most of the core code is very refined and stable. I'm really lost on what to do, so I ask here: Whats the standard way to deal with this kind of situation? Do most forks start over again, bump up version numbers, or do something else that I'm not aware of.

• I want to fix a bug. Where do I start?

  - by Ingo Gerth

  Although I am not a professional programmer, I have written a program or two. Yet, nowadays every engineer and scientist learns to program a bit as well, and as such I am used to writing programs in Python, C and MATLAB. Now I want to give back a bit to Ubuntu and its great folks and fix a bug! I had a look at the list of the bitesize campaign and had to find that most of them are not that easy for me to fix as I suspect they require a lot of time to get into the matter, and I do not have that. Still I discovered this one and it looks manageable and like a cool feature to me. As I have never written a patch or released a program to the wild before though, I have no idea where to start. What should be my first step to tackle that problem? Bottom line: Where and how do I start fixing that guy?

• How can I implement full disk encryption for a disk containing Ubuntu with plausible deniability?

  - by Rupert

  I would like to have a disk that: has Ubuntu installed is fully encrypted is setup in such a way as to make denial of the existence of the Ubuntu install plausible Truecrypt provides the last two features but only for Windows: http://www.truecrypt.org/docs/?s=sys-encryption-supported-os The alternate installer for Ubuntu provides the first two features but not the last. I imagine that plausible deniability would be achieved by, at least: Having two installs of Ubuntu and 2 passphrases (or keyfiles) which would unencrypt each one. Moving any unencrypted data (such as /boot) onto a USB stick Are there any programs out there which support this feature set for Ubuntu?

• Is there an application or method to log of data transfers?

  - by Gaurav_Java

  My friend asked me for some files that I let him take from my system. I did not see he doing that. Then I was left with a doubt: what extra files or data did he take from my system? I was thinking is here any application or method which shows what data is copied to which USB (if name available then shows name or otherwise device id) and what data is being copied to Ubuntu machine . It is some like history of USB and System data. I think this feature exists in KDE This will really useful in may ways. It provides real time and monitoring utility to monitor USB mass storage devices activities on any machine.

• Comparisons of Javascript 'data grids'?

  - by Joe

  I've found plenty of questions between here and StackExchange of people asking for the 'best' data grid / data table, or one that has a particular feature, and plenty of lists out there (of various ages) listing the various data grid implementations ... but is anyone aware of any matrix of what features the various solutions implement? (eg, allow shift-click to select multiple; support checkboxes for selection; can update a regular table in-place; allow editing of cells; support websql or indexeddb for local caching; which browsers they support; infinite scroll; etc.) There's a generic 'javascript framework' comparison on wikipedia, which would be the sort of thing I'm looking for, but it doesn't go into detail on data grids. (which makes sense, as so many are extensions, not core features of those frameworks, and in the case of jQuery, there's lots of 'em.)

• How to remove text from file icons ?

  - by Jesse

  I am fairly new to Ubuntu (Linux). I noticed when creating a .java file or .py gives me an icon, however when I start writing code it overrides the thumbnail into showing text. Is there a way to disable this silly feature ? When I installed Linux Mint on the VM I noticed I was able to accomplish this task by unchecking "Show text in icon". I know they use Namo as their file manager. I read this thread and it did not work. How to stop Nautilus from creating thumbnails of specific file types?

• Ubuntu 13.10 vs 12.04 LTS

  - by Shaun

  I am migrating my workflow to ubuntu from windows. I have a macbook pro at home and I really enjoy being able to use the workspaces feature on ubuntu to increase my productivity. As myself being someone that isn't very familiar with doing command line things and hasn't worked with linux a whole lot other than doing basic commands like cd, ls, rm, screen, and sudo. I was wondering what you think would be the best choice for a ubuntu version. I am looking for ease of use as well as stability. I spend most of my time working with eclipse, as well as writing documents. On a side note, right now I have a pretty high end workstation, but I am using a crappy notebook 2.5 inch 1TB hard drive for my system. Would it be worth it to switch to a top of the line SSD, or would the difference not really be noticeable? How difficult would it be for a newcommer to setup the system with the os and important folders running on a SSD and then other folders for storage running on a HD.
