• HTML5 clicking objects in canvas

  - by Dave

  I have a function in my JS that gets the user's mouse click on the canvas. Now lets say I have a random shape on my canvas (really its a PNG image which is rectangular) but i don't want to include any alpha space. My issue lies with lets say i click some where and it involves a pixel of one of the images. The first issue is how do you work out the pixel location is an object on the map (and not the grass tiles behind). Secondly if i clicked said image, if each image contains its own unique information how do you process the click to load the correct data. Note I don't use libraries I personally prefer the raw method. Relying on libraries doesn't teach me much I find.

• Tons of problems a new user is encountering

  - by Barney

  I've borrowed this laptop from a friend. I wanted to install AdBlock to boost performance. First weird thing was that even though I was on Chrome, Chrome suggested me installing him? So I tried to install ,than it gave me some message about broken dependencies. I Googled and tried to run those commands you guys were suggesting, but than it popped up error messages about everything again. Than I found out that some package called linux image generic is broken, than I tried to find an answer to that, but on the topic it was ” ndk.bhj\spo;ujvsdljvaEOYUFgidgAPIF;hsgvk in other words, I didn't understand anything about it, than there's this thing: E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? Seriously, when I'm trying to fix an error, there is another one. I'm on something called GNOME. Sooo, where do I start?

• Is there a way to emulate pinch-zoom?

  - by aking1012

  I'm looking for a way to emulate pinch zoom in either an android emulator(android SDK-less desirable) or a (preferred) native Ubuntu web browser that I can resize to a specified size for initial testing of HTML5 applications. This is would be useful for first round testing during cross-platform application development. Note: I'm trying to do this with no real touch-device only a mouse. So the best answer would be something like "Install this chromium plug-in and use this hotkey to set pinch points" or something similar. We already have this for getting dual mouse working(thanks AmithKK). The browser that supports multi-touch is the hard part. Something to note is that I start getting screen artifacts using multiple mice via that guide. They're mild and tolerable, but they are there.

• How to identify potential for becoming a programmer

  - by Jacob Spire

  There's heaps of information out there on hiring someone who's already a programmer. (Or claims to be one.) But what about identifying someone who has the potential to become a programmer, with little or no knowledge? Aside from the obvious things to look for (smart, gets things done), are there any interview questions and/or tests to determine whether one has the potential to become a programmer? Note: I'm not asking how to tell whether I can learn programming, but how to tell someone else is right for it.

• How to verify the Liskov substitution principle in an inheritance hierarchy?

  - by Songo

  Inspired by this answer: Liskov Substitution Principle requires that Preconditions cannot be strengthened in a subtype. Postconditions cannot be weakened in a subtype. Invariants of the supertype must be preserved in a subtype. History constraint (the "history rule"). Objects are regarded as being modifiable only through their methods (encapsulation). Since subtypes may introduce methods that are not present in the supertype, the introduction of these methods may allow state changes in the subtype that are not permissible in the supertype. The history constraint prohibits this. I was hoping if someone would post a class hierarchy that violates these 4 points and how to solve them accordingly. I'm looking for an elaborate explanation for educational purposes on how to identify each of the 4 points in the hierarchy and the best way to fix it. Note: I was hoping to post a code sample for people to work on, but the question itself is about how to identify the faulty hierarchies :)

• Alexa indexing browsing history?

  - by Haluk

  We have this test.php sitting around in a forgotten folder. It is a script which just sends an email to our site admin. We never had a page linking to it. It is not indexed by Google. It does not exist in the Internet Archive Wayback Machine. But every now and then it gets crawled by ia_archiver. I wonder how it got indexed. Could it be because of the Alexa toolbar installed on our computer? Does Alexa index our personal browsing history?

• brother MFC-J435W wireless scanning issue

  - by ogreen32

  Thanks for taking the time to read this. I have a brother MFC-J435W and I was able to get the printer set up for wireless printing, but it is not allowing me to scan wirelessly. It gives me the message to "check connection". I'll tell you what I've done so far and maybe someone can help me out. I've installed the scanner driver and scan tool I installed Xsane (to see if it would allow the scanner to communicate with the computer and that didn't help). I've tried restarting the computer. After those things I am now at a loss as to where to go from here. Any help would be great. Thanks. I've also searched for this question in the Brother FAQ as well as on here and I haven't found an answer. Thanks again.

• Allowed keywords for adwords [closed]

  - by Tom Gullen

  Possible Duplicate: Ok to target product names in adwords? I've replaced relevant words away from the real world without losing semantics which is a little difficult. A competitor is called "Box Maker" Can I target the keywords: "box maker" if my company is selling a tool to help you make boxes? Or is that disallowed? Would "Box Maker" the company be able to file a complain on Google? Would it go anywhere? The term 'box maker' gets a lot of searches and is an incredibly cost effective search to target

• Banshee won't sync OGG format to my iphone

  - by Daze

  I have a jailbroken iphone 3g with 16 gigs of memory and I've been putting my music on it from banshee lately and have been having almost no issue. Unfortunately, I just added a few albums to my Banshee library and tried to sync them to my iphone, but every time I try, i see a hundred or so errors saying that the device doesn't support the ogg format and there was no converter found. I'm still pretty much a newb at this stuff, so please help me and dumb down your answer. I'm running 12.04 and again, using an iphone 3g with no sim card, but it's been jailbroken and is used primarily for it's music function.

• HDMI Audio stops after TV turned off

  - by Ryan

  After the 12.04 Update my HDMI audio stops working anytime I turn off my 2nd monitor(plasma TV). Graphics card is a Radeon 6800 which has DVI out to 1st monitor, HDMI out to receiver which the TV gets it's Audio/Video. Audio is always via my receiver sound. Things work fine as long as it boots with the TV and Receiver on. Turn off the TV and BART's HDMI audio will go away, and the HDMI option vanishes from the sound menu. I had an occasional HDMI issue with 11.10 but turning on/off the TV would fix the sound. How can I hardcode things so that it always uses HDMI out of audio? I suspect the TV is sending a signal upon that 12.04 is now listening for. Turning the TV back on does NOT resolve this, and I'd suggest having the ability to override this new "feature" via sound menu.

• Booting 11.10 from USB stick on MacBook Pro 5,1 fails

  - by Helge Stenström

  I've created a bootable memory stick on a Windows computer, and tested it on an HP PC. It's made from a 64-bit image of Ubuntu 11.10, downloaded from http://www.ubuntu.com/download/ubuntu/download. When I boot from this memory stick, there is some kind of boot menu, where I can choose to run Ubuntu from the memory stick, or install. I select Run from memory stick. (the words may be wrong here, I'm taking it from memory.) From this point, the screen is black (but backlighted), and I can't do anything but turn off the computer. It gets hot, too. Has anyone been more successful than me? Are there known issues? The computer is a 15 inch MacBook Pro 5,1 (unibody, late 2008), 4 GB memory.

• Rewrite rule to show as directory using .htaccess

  - by chanchal1987

  I want to implement a rewrite rule in my .htaccess file to show a specific url as a directory of my server. See the code below I written, RewriteRule ^(.*)/$ ?page=$1 [NC] This will rewrites urls like www.mysite.com/abc/ to www.mysite.com/index.php?page=abc. But if I request www.mysite.com/abc then it is throwing an 404 error. How can I write a rewrite rule which will match www.mysite.com/abc and www.mysite.com/abc/ both? Edit: My current .htaccess file (After Litso's answer's 3rd revision) is like below: ## ErrorDocument 401 /index.php?error=401 ErrorDocument 400 /index.php?error=400 ErrorDocument 403 /index.php?error=403 ErrorDocument 500 /index.php?error=500 ErrorDocument 404 /index.php?error=404 DirectoryIndex index.htm index.html index.php RewriteEngine on RewriteBase / Options +FollowSymlinks RewriteRule ^(.+)\.html?$ $1.php RewriteCond !-d RewriteRule ^(.*)/$ ?page=$1 [NC,L] RewriteCond %{REQUEST_URI} !index.php RewriteRule ^(.*)$ ?page=$1 [NC,L] ##

• Does NASA license the software that it develops?

  - by Abe

  NASA provides a visualization software called Panoply. There is a Credits and Acknowledgments page that acknowledges and lists the licenses of software dependencies, but provides no information about its own license. I have looked at other software produced by NASA, including the source code for GISS and can not find any information about a licence. The closest information that I can find is in the FAQ for the global climate model EdGCM Global that says the code is in the "public domain" is it standard practice at NASA to release code into the public domain? are there exceptions? Can I assume that Panoply is public domain and can be used without restriction other than than those imposed by licenses of software dependencies? Is the absence of specific permission to reuse the code a concern (this issue was raised in the answer to a separate question) How common is this practice across government agencies?

• How to calculate Sin function quicker and more precisely?

  - by user1297181

  I want to calculate y(n)=32677Sin(45/1024•n), where y is an integer and n ranges from 0 to 2048. How can I make this process quicker and more precisely? Now I want to show you a reference answer: Since Sin(a+b)=Sin(a)Cos(b)+Cos(a)Sin(b) And Cos(a+b)=Cos(a)Cos(b)-Sin(a)Cos(b). So I can store Sin(45/1024•1) andCos(45/1024•1) ` only.Then use this formula: Sin(45/1024•2)=Sin(45/1024•1+45/1024•1), Cos(45/1024•2)=Cos(45/1024•1+45/1024•1), .... `Sin(45/1024•n)=Sin(45/1024•(n-1)+45/1024•1) `, `Cos(45/1024•n)=Cos(45/1024•(n-1)+45/1024•1) `, This way maybe quicker without storing large array.

• Can't type my username and password, random freeze at login

  - by rakesh

  My netbook runs a dual OS(Windows7 & Ubuntu 12.04). After Ubuntu login screen appears, that’s it, it gets hanged, can't even move my cursor nor type my user name. I had to turn off my system and boot again. Still its not sure that it won't freeze out at login screen again, but this is the temporary solution I have to get into Ubuntu. This freezing at login screen doesn't happen every time, it happens randomly. It seems like I had to enter into Ubuntu purely based on my luck, which is quite irritating. I found many other types of login problem in Ubuntu when I googled, which were quite different from my case. So any1 kindly help me out.

• Twitter's new approach of third party application? How would you see this move as developer.... especially you plan to build a twitter client.

  - by MobileDev123

  Just today morning I have read news that twitter has issued a warning to developers not to make any new third party client, the official announcement can be read here. As a programmer, how do you see this move of twitter? Does it seems that they want to standardize the behavior of third party client or they don't want any new client in favor of the default clients they have made? What if anybody wants to create a new client? Is there any guidelines that-if followed- ensure that we can create a new mobile client? Or we should stop thinking about it? What are the option for the developers who want to build some clients for twitter? I can realize that I have asked too many questions, but I still think that there can be one common answer.

• Can't get Past Login Screen -Graphics Drivers 12.10

  - by mchangun

  Newbie Linux user here. I just installed Ubuntu 12.10, dual booting with Windows 8 Preview Release Build 8400 on a Dell Precision 490 workstation with Nvidia Quandro NVS 55/280 PCI graphics card. I cannot login to Ubuntu - after entering my password and pressing enter, the screen graphics gets garbled for a few seconds, and then the screen goes black showing only the mouse cursor. I suspect it's something to do with my Graphics Card, everything on the GUI login screen feels very sluggish. I know what I have provided here doesn't give you much information, would appreciate it if I could get some guidance on how to provide more useful logs. Thank you.

• PHP composer question

  - by kdub

  just getting started with composer and I have a couple of questions. When I use composer to add a dependency, the dependency gets added to my folder's Vendor directory. The newly added package not only comes with the source code for that package, but all packagist required files for the developer to test and add that package to packagist repo (composer.json, .travis.yaml, license, readme.md, etc). For my project, do I need to keep the vendor's required packagist files in my project? Can I clean the package folder structure up a little? I added the package, Slim micro framework, which nests the source files three directories deep upon installation, ../vendor/slim/slim/Slim/(source Files). Is it worth moving these files to the top Slim directory like: ../vendor/Slim/(source files)? Or will this ruin the integrity of the package?

• How do I efficiently generate chunks to fill entire screen when my player moves?

  - by Trixmix

  In my game I generate chunks when the player moves. The chunks are all generated on the fly, but currently I just created a simple flat 8X8 floor. What happens is that when he moves to a new chunk the chunk in the direction of the player gets generated and its neighboring chunks. This is not efficient because the generator does not fill the entire screen. I did try to use recursion but its not as fast as I would like it to be. My question is what would be an efficient way of doing so? How does minecraft do so? When I say this I mean just the way it PICKS which chunks to generate and in what order. Not how they generate or how they are saved in regions, just the order/way it generates them. I just want to know what is a good way to load chunks around the player.

• LL(8) and left-recursion

  - by Peregring-lk

  I want to understand the relation between LL/LR grammars and the left-recursion problem (for any question I know parcially the answer, but I ask them as I don't know nothing, because I am a little confused now, and prefer complete answers) I'm happy with sintetized or short and direct answers (or just links solving it unambiguously): What type of language isn't LL(8) languages? LL(K) and LL(8) have problems with left-recursion? Or only LL(k) parsers? LALR(1) parser have troubles with left or right recursion? What type of troubles? Only in terms of the LL/LALR comparision. What is better, Bison (LALR(1)) or Boost.Spirit (LL(8))? (Let's suppose other features of them are irrelevant in this question) Why GCC use a (hand-made) LL(8) parser? Only for the "handling-error" problem?

• From Imperative to Functional Programming

  - by user66569

  As an Electronic Engineer, my programming experience started with Assembly and continue with PL/M, C, C++, Delphi, Java, C# among others (imperative programming is in my blood). I'm interested in add to my previous knowledge, skills about functional programming, but all I've seen until now seems very obfuscated and esoteric. Can you please answer me these questions? 1) What is the mainstream functional programming language today (I don't want to get lost myself studying a plethora of FP languages, just because language X has the feature Y)? 2) What was the first FP language (the Fortran of functional programming if you want)? 3) Finally, when talking about pure vs. non pure FP what are the mainstream languages of each category? Thank you in advance

• Just installed 12.04 and it freezes when I try logging in

  - by James

  I just installed Ubuntu 12.04 alongside Windows 7 on an Acer Aspire 1 with AMD Dual-Core C60, 4 GB RAM, and 320 GB HDD (100 GB partitioned for Ubuntu). After restarted my computer, I was able to log in fine but when I tried to log in again after shutting my netbook off, it began to freeze on the log in screen. The freezing occurs several seconds after I'm prompted to enter my password. Even if i enter the password before the freezing occurs, I end up getting stuck while it's loading or something. I'm new to Ubuntu so I have no idea what to do. Also, before it gets to the log in screen, it says something like this: NTFS5: No wubildr NTFS5: No wubildr NTFS5: error: "prefix" edit: it was wubildr, not unbilder. Also, the freezing seems to be inconsistent
