[ "Play Youtube Video Full Screen in Browser", "My question: Is iOS the only OS that will play an embedded Youtube video at fullscreen by default? If so, is it possible to safely display a youtube video at fullscreen (or close) in a non-iOs device?\n\nThe situation is that I have a group of webpages that contain a youtube video on each page. The idea is to keep the User inside the group of webpages (until they \"Exit\" out of the group), so therefore I am not showing any related videos, and the only other links on the page are links to the other pages within the group (and the \"Exit\" button).\n\nThe problem is that I can't deliver a consistent cross device experience. As far as I can tell, the only way to play a Youtube video fullscreen is to the open up the Youtube App. I do not want to do that because I don't want to break the experience of my quasi-app.\n\nI found this thread, which seemed hopeful, but linking to a watch_popup url triggers the Youtube App on Droid devices. \n\nI could embed the video using the Youtube API, then display that video in a modal when the user wants to play the video. But doing this disturbs the experience on iOS devices since the video already plays at fullscreen by default.\n\nFrom my perspective, it seems I need to detect the userAgent, and if the userAgent is Not iOS, then display video in a modal window. Detecting userAgent seems so 2001, so is there a better way?" ]

[ "An invalidated form does not get its validity recalculated when offending element removed from DOM", "I use ctrl.$setValidity within one of my directives to invalidate a form. However, there is a method residing elsewhere which could remove this element from the DOM under a different set of conditions. What happens when I invalidate the form with $setValidity and then remove the offending element is that the form remains invalid, while what I would like it to do is to recalculate its validity based on its new Inputfield set.\n\nPlease note that I am not simply looking for a ctrl.$setValidity true, (other input fields in the form may or may not be valid), I simply want the form to recalculate.\n\nBelow is the directive code:\n\n app.directive('dir', function() {\n return {\n restrict: 'C',\n require: \"ngModel\",\n link: function(scope, element, attrs, ctrl) {\n someValue = scope.someValue;\n someField = element.find(\".some-class\");\n\n monitorField = function(newValue, oldValue){\n console.log(\"whee\");\n scope.someFunction(newValue);\n if(newValue ==\"Invalidate NOW!\"){\n ctrl.$setValidity('someClass', false); \n } else if (oldValue == \"Invalidate NOW!\"){\n angular.element(document.querySelector('.some-class')).remove();\n } else {\n ctrl.$setValidity('someClass', true); \n }\n } \n scope.$watch(\"someValue\", monitorField, true);\n }\n }\n});\n\n\nWhich operates on:\n\n <FORM class=\"dir\" ng-model=\"someValue\">\n <INPUT type=\"text\" class=\"some-class\" ng-model=\"someValue\"/>\n <INPUT type=\"text\" class=\"some-other-class\"/>\n </FORM>\n\n\n(Yes it is a somewhat contrived example). \n\nThe problem is reproduced here: http://jsfiddle.net/kTuAY/\n\nIn my actual code, I populate the input fields based on an array of objects, which gets populated via Service, and remove elements via array.splice. The example given in the jsfiddle is merely there for simplicity.\n\nAnother interesting condition of failure can be seen in this fiddle:\n\nhttp://jsfiddle.net/JACAv/\n\nSpecifically, if one of the inputs depends on non collision of value with the other, and is thusly invalidated, whereafter the other fields value is changed, validity remains incorrect.\n\nTemporary not quite functioning fiddle while I go to work:\n\nhttp://jsfiddle.net/yQpHL/\n\nThanks!" ]

[ "What's a good way to generate a random number for a valid credit card?", "I am developing a set of tools in Java for validating and working with credit cards. So far I have support for:\n\n\nLUHN validation.\nDate validation (simple expiration).\nCard code length validation (CVV, CVC, CID) based on the brand (Visa, MasterCard, etc).\nCredit card number length validation (based on the brand).\nBIN/IIN validation (against a database of valid numbers).\nHiding the digits (425010 * * * * * * 1234)\n\n\nTo make the tool set a bit more complete, I would like to create a credit card random number generator based on the different card brands. This functionality will (hopefully) make my test cases a bit more reliable.\n\nBasically, I would like to be able to generate numbers which are:\n\n\nLUHN valid\nValid based on the brand prefixes\nValid based on the BIN/IIN prefix numbers\n\n\nFor BIN/IIN valid card numbers, I am thinking of looking up a random BIN/IIN number from the database (based on the brand of course) and then appending the remaining digits using Random. Obviously, that would not be valid most of the time and I will have to increment one of the digits until it passes the LUHN validation.\n\nI can't seem to be able to think of a better way. Perhaps someone could suggest something a little smarter...?\n\nLooking forward to your suggestions! Thanks in advance! :)" ]

However Clifford's good suggestion could not deal with the size_t data type (we need a size after all!), so I guess that the most practical approach in the end would be to use a pointer for storing the size of the file, and keep the return value of our dedicated function only for failures. Here is my contribution to Clifford's solution for a safe size calculator:\n\nint fsize (FILE * const file, size_t * const size) {\n\n long int ftell_retval;\n\n if (fseek(file, 0, SEEK_END) || (ftell_retval = ftell(file)) < 0) {\n\n /* Error */\n *size = 0;\n return 1;\n\n }\n\n *size = (size_t) ftell_retval;\n return 0;\n\n}\n\n\nSo that when we need to know the length of a file we could simply do:\n\nsize_t file_size;\n\nif (fsize(my_file, &file_size)) {\n\n fprintf(stderr, \"Error calculating the length of the file\\n\");\n return 1;\n\n}" ]

A nice and fast way to do this is to not completely clear the canvas each frame, but overlay it with semi-transparent color. Here is an example with just one particle:\n\n\r\n\r\nvar canvas = document.getElementById('display');\r\nvar ctx = canvas.getContext('2d');\r\nvar displayHeight = canvas.height;\r\n\r\nvar backgroundColor = '#000000';\r\nvar overlayOpacity = 0.05;\r\n\r\nvar testParticle = {\r\n pos: 0,\r\n size: 3\r\n};\r\n\r\nfunction render(ctx, particle) {\r\n ctx.globalAlpha = overlayOpacity;\r\n ctx.fillStyle = backgroundColor;\r\n ctx.fillRect(0, 0, canvas.width, canvas.height);\r\n ctx.globalAlpha = 1.0;\r\n \r\n ctx.fillStyle = '#FFF';\r\n ctx.fillRect(particle.pos, displayHeight / 2, particle.size, particle.size);\r\n}\r\n\r\nfunction update(particle) {\r\n particle.pos += 1;\r\n}\r\n\r\n// Fill with initial color\r\nctx.fillStyle = backgroundColor;\r\nctx.fillRect(0, 0, canvas.width, canvas.height);\r\n\r\nfunction mainLoop() {\r\n update(testParticle);\r\n render(ctx, testParticle);\r\n requestAnimationFrame(mainLoop);\r\n}\r\n\r\nmainLoop();\r\n<canvas id=\"display\" width=\"320\" height=\"240\"></canvas>\r\n\r\n\r\n\n\nThere is an apparent problem: with low opacity values, the trail never fades away completely. You can see the horizontal line that (almost) does not fade in my single-particle example. I understand why this happens. ColorA overlayed by semi-transparent ColorB is basically a linear interpolation, and ColorA never fully converges to ColorB if we repeatedly do the following:\n\nColorA = lerp(ColorA, ColorB, opacityOfB)\n\n\nMy question is, what can I do to make it converge to the background color, so that trails don't remain there forever? Using WebGL or drawing trails manually are not valid options (because of compatibility and performance reasons respectively). One possibility is to loop over all canvas pixels and manually set pixels with low brightness to background color, although it may get expensive for large canvases. I wonder if there are better solutions." ]

[ "Proper Management Of A Singleton Data Store In IOS With Web Service", "I'm currently using a singleton as a data store for my app. I essentially store a number of events that are pulled and parsed from a web service and then added as needed. Each time I make a request from the web service, I parse the results and see if the items already exist. If they do, I delete them and add the updated version provided by the web service. \n\nEverything appeared to be working properly until I fired up the Instruments panel to find out that my system is leaking the objects every time it loads them from the web service (from the second time on). The core method where things appear to be messing up is this one, which is located in my HollerStore singleton class:\n\n- (void)addHoller: (Holler *)h\n{\n //Take a holler, check to see if one like it already exists\n int i = 0;\n\n NSArray *theHollers = [NSArray arrayWithArray:allHollers];\n for( Holler *th in theHollers )\n {\n if( [[th hollerId]isEqualToString:[h hollerId]] )\n {\n NSLog(@\"Removing holler at index %i\", i);\n [allHollers removeObjectAtIndex:i];\n }\n i++;\n }\n [allHollers addObject:h];\n}\n\n\nQuick explanation: I decided to copy the allHollers NSMutableArray into theHollers because it's being updated asynchronously by NSURLConnection. If I update it directly, it results in a crash. As such, I switched to this model hoping to solve the problem, however the Instruments panel is telling me that my objects are leaking. All the counts are exactly the # of items I have in my data set. \n\nFrom what I can tell removeObjectAtIndex isn't effectively removing the items. Would love to get the thoughts of anybody else out there on three things:\n\n\nIs my analysis correct that something else must be retaining the individual hollers being added? \nShould I be using CoreData or SQLite for storing information pulled from the web service? \nDo you know how long data stored in a Singleton should be available for? Until the app is killed?\n\n\nUpdate\nI think I've found the source, however perhaps someone can provide some clarity on the proper way to do this. I've created a method called parseHoller which takes a dictionary object created through SBJSON and returns my own model (Holler). Here are the last couple lines:\n\nHoller *h = [[[Holler alloc] initFromApiResponse:hollerId \n creatorId:creatorId \n creatorName:creatorName \n creatorImageUrl:creatorImage \n comments:comments \n attendees:attendees \n wishes:wishes \n invitees:invites \n createdAt:createdAt \n text:text \n title:title \n when:when]autorelease];\n//(some other autorelease stuff is here to clean up the internal method)\nreturn h;\n\n\nI figured that since I'm returning an autoreleased object, this should be fine.

[ "How to give docker container write/chmod permissions on mapped volume?", "I have a synology NAS which has docker support and wanted to run some docker containers (I'm pretty new to Docker) on it. For example pocketmine-pm (but I believe I have the write issue also with other containers).\n\nI created a volume on the host and mapped this in the container settings. (And in the synology docker settings for the volume mapping I did not click on \"read only\").\n\nAccording to the Dockerfile a new user 'pocketmine' is created inside the container and this user is used to start the server. The user seems to have the user ID 1000 (first UID for new linux users). The container also uses an Entrypoint.sh script to start the server.\n\nInitially the container was not able to write files to the mapped directory. I had to SSH into the host 'chown' the directory for the UID 1000:\n\nsudo chown 1000:1000 /volXy/docker/pocketminemp -R\n\n\nAfter that the archive could be downloaded and extracted.\n\nUnfortunately I was not able to connect to the server from my iOS device. The server is listed as 'online' but the connection fails without any specific message. I then checked the logs of the container and saw the following entries (not sure if this really prevents the connection but I will give it a try):\n\n[*] Everything done! Run ./start.sh to start PocketMine-MP\nchown: changing ownership of '/pocketmine/entrypoint.sh': Operation not permitted\nchown: changing ownership of '/pocketmine/server.properties.original': Operation not permitted\nLoading pocketmine.yml...\n\n\nApparently the container cannot chown a file it was previously able to download.\n\nDoes anybody know what can be done to fix this? Do I need to chmod the mapped volume and why did I need to chown the directory to UID 1000 (a user that doesn't really exist on the host) - isn't there a more elegant way to fix the permissions?" ]
