"Five square elements inside a variable-size container",
"I have a variable-sized container (the dimensions are a percentage of the viewport size)\nInside it, I want to place five perfectly-square elements without resizing the container. As the aspect ratio of the container almost never will be 5:1, there will be some space around the elements.\nFor the case where the aspect ratio is greater than 5:1, the extra space will be at the sides of the elements:\n\n(The elements are the blue squares, the container is in cyan. I have two of the containers in this page.)\nFor this, the container is a Flexbox, with the elements containing a single 1x1 transparent image with a height of 100%, and the rest of the content as an absolute element in order to not resize the elements.\n\nFor the case where the aspect ratio is less than 5:1, the extra space will be on top and on the bottom of the elements:\n\n(Same as before)\nFor this, the container is still a flexbox, but the image has display: none, the width of each element is set to 100% and each element as a ::before with padding-bottom: 100%\n\nThis works for the two separate cases, but not to swap between them. Currently I have a media query that swaps between the two solutions at some precalculated screen aspect ratio, but this does not work after adding some paddings to the page.\nIs there a better way of having five square elements, that will just occupy whatever space is available without deforming the container?"

Running my test again after a reset would bring up the second error which is even more bizarre since the test needs to run THROUGH this point to even get to the username which we reached in the first run.

If I try to load it this way, it fails with error message in the console (\"Cannot read property 'module' of undefined,\" etc.):\n\n<script>\nwindow.onload = function () {\n var loadScript = function (url, type) {\n var script = document.createElement('script');\n script.src = url;\n if (type === 'application/json') {\n script.type = type;\n }\n document.body.appendChild(script);\n };\n\n loadScript('javascript/angular.min.js', '');\n loadScript('javascript/angular.min.js.map', 'application/json');\n loadScript('javascript/angular-route.min.js', '');\n loadScript('javascript/angular-route.min.js.map', 'application/json');\n};\n</script>\n\n\nThis also fails if the routine is not restricted to the window.onload event:\n\n<script>\nvar loadScript = function (url, type) {\n var script = document.createElement('script');\n script.src = url;\n if (type === 'application/json') {\n script.type = type;\n }\n document.body.appendChild(script);\n};\n\nloadScript('javascript/angular.min.js', '');\nloadScript('javascript/angular.min.js.map', 'application/json');\nloadScript('javascript/angular-route.min.js', '');\nloadScript('javascript/angular-route.min.js.map', 'application/json');\n</script>\n\n\n...and it makes no difference if I grab the files from local hosting or from Google's Ajax CDN.\n\nAny clue how to solve this? With the 'strict-dynamic' CSP, I have no choice but to load the AngularJS framework files using a technique like the ones above."

"I am having conflict issues between Google Plus and Youtube Data API?",
"So I have a site I'm working on which includes searching for videos using Google's YouTube Data API v3 (I am using the javascript library). Everything works fine prior to including new code on the same page importing Google+'s code to use it's share functionality. Now whenever I load the page, neither the YouTube video searches nor sharing via Google Plus seems to work. Below is the code for YouTube's Data API client load and search:\n\nfunction initializeGapi() {\n gapi.client.setApiKey(API_KEY); // client API_KEY variable for client\n gapi.client.load('youtube', 'v3', \n function() { \n console.log('Youtube API loaded.');\n searchYoutube(''); // searches youtube\n }\n );\n}\n\n\nThis HTML tag is included in the header of the page:\n\n<script src=\"https://apis.google.com/js/client.js?onload=OnLoadCallback\"></script>\n\n\nSo everything was working well.

"Keeping a variable alive across multiple function calls in rust",
"I am trying to memoize a recursive collatz sequence function in rust, however I need the hashmap of memoized values to keep its contents across separate function calls. Is there an elegant way to do this in rust, or do I have to declare the hashmap in main and pass it to the function each time? I believe the hashmap is being redeclared as an empty map each time I call the function. Here is my code:\n\nfn collatz(n: int) -> int {\n let mut map = HashMap::<int, int>::new();\n if map.contains_key(&n) {return *map.get(&n);}\n if n == 1 { return 0; }\n map.insert(n, \n match n % 2 {\n 0 => { 1 + collatz(n/2) }\n _ => { 1 + collatz(n*3+1) }\n }\n );\n return *map.get(&n);\n}\n\n\nOn a side note, why do I need to add all of the &'s and *'s when I am inserting and pulling items out of the HashMap? I just did it because the compiler was complaining and adding them fixed it but I'm not sure why. Can't I just pass by value? Thanks."

The VBA-Python call will happen many times.\nMy first idea is based on a text file communication, e.g. something like this:\nin VBA:\ndo something\n\nwrite text file 'calc_todo.txt' in specific directory\n\nwhile not exists 'calc_finished.txt':\n wait 1 second\n\nread 'calc_finished.txt'\n\ndelete'calc_finished.txt'\n\ndelete'calc_todo.txt'\n\ndo something\n\nwrite text file 'calc_todo.txt' in specific directory\n\n... repeat\n\n\n\nin Python:\ndo something\n\nwhile not exists 'calc_todo.txt':\n wait 1 second\n\nread 'calc_todo.txt'\n\ndo calculations based on 'calc_todo.txt'\n\nwrite 'calc_finished.txt'\n\ndelete'calc_todo.txt'\n\ndo something\n\nwhile not exists 'calc_todo.txt':\n wait 1 second\n\n... repeat\n\nI have done something similar in past and unfortunately there are a lot of things I do not like:\n\nfixed waiting time of e.g. 1 second might slow down performance\nif something breaks VBA and/or Python will get stuck in a while loop or run in an error\nto fix the second issue, error handling with initialisation can be implemented but last time it was a mess\n\nWhat would be a more professional way on how to handle such communication?"

"Migrating Db and Entity framework",

So the new database has other columns and tables than the old one.\n\nSo basically I need to read tables from the old database and put that data into the new structure, some data won't be used anymore and other data will be placed in other columns or tables etc.\n\nMy plan was to just read the data from the old database with basic queries like \n\nSelect * from mytable\n\n\nand use Entity Framework to map the new database structure. Then I can basically do similar to this:\n\nwhile (result.Read())\n{\n context.Customer.Add(new Customer\n {\n Description = (string) result[\"CustomerDescription\"],\n Address = (string) result[\"CuAdress\"],\n //and go on like this for all properties\n });\n}\ncontext.saveChanges();\n\n\nI think it is more convenient to do it like this to avoid writing massive INSERT-statements and so on, but is there any problems in doing like this? Is this considered bad for some reason that I don't understand. Poor performance or any other pitfalls?

And so the person who is attempting to use my application will wait 20 seconds. Then all the new requests will come to the new dynamic instance. \nThe response time on my resident instances are inferior to my min pending latency (5 sec). \nMy app is in production since yesterday and if no one uses it for 5 minutes then the next guy who will connect will have to wait 20 sec ! \n\nFrom what I ve read, some would say that if I set min idle instance to 4 ( in order to have my resident instances) GAE will try to have 4 iddle instances all the time and so we ll start new instances; but then I would always have to wait 35 sec for all my first connections After 2 minutes of using the application everything is fine.\nA guy working at Google told me that there is a bug in the management of resident instances and that I have to have 3 resident instances to have a quick answer for my users. \nI m sure I haven t understood something.

"How to use git branches",
"being new to git, I have this dumb question - what is the correct way of using feature-branches ?\n\nFrom what I have gathered, this is how I thought it should be used:\n\ngot some 'develop' branch from which branches are checked out:\n\n\"feature-1\"\n\"feature-2\"\n\"feature-3\"\n\n\netc.\n\nNow, one or more developers would work on one or more feature branches, and when the team leader wants to glue everything back together and test he would then merge the features back into the 'develop' trunk. \nHowever, git appears to lack the ability to hand pick what changes to keep from each feature branch (tried recursive, patience and every other merge strategy) so in the end, sometimes each of the branch ends up overwriting what previous branches merged back into 'develop'.\nThings get even nastier as developers continue to work on their branches and team leader attempts to merge them into 'develop' from time to time to incorporate the changes.\n\nObviously this is not the right way to branch-for-feature. But what is the right way then ?\n\nthanks\n\nEDIT:\n\nJust to illustrate further, let's consider we have these files in develop branch:\n\nfileA (develop)\nfileB (develop)\nfileC (develop)\n\n\nNow merge back in \"feature-1\" which only touches fileA:\n\nfileA (conflict, theoretically solvable by the recursive/theirs strategy)\nfileB (develop)\nfileC (develop)\n\n\nNext merge back \"feature-2\" that only touches fileB:\n\nfileA (overwritten by feature-2!!!)\nfileB (conflict, theoretically solvable by the recursive/theirs strategy)\nfileC (develop)\n\n\nWhat to do about fileA ?

"C makefile and header confusion",
"I have a couple of general questions about Make files, headers, and including files in C, and am hoping to get an easy to interpret answer because all the tutorials go from \"ok I understand this\" to \"what the heck is this\" just in a couple lines. \nLets say I have a program I want to create a makefile for.\n\n**fileA.c** contains the main and calls functions in **fileB.c** and **fileC.c**\n\n**fileB.c** contains getopts and stdlib but no other file or function from other file\n\n\n(so normal headers, correct? nothing linking to any other file since it doesn't call anything. Or should it have fileA.c header since it is called from there?)\n\n**fileC.c** contains functions that call header1.h (given header file for library)\n\n\nI am just confused what headers are included and what I put in the make file to support make/clean functions. Since fileA.c calls functions from fileB.c and fileC.c do i create headers for them and #include them in fileA.c or do I write that into the makefile?\n If I include a header for something in the file and then create a makefile for the file, does it go to the pre-processor twice?\n\nI think I may just be confused in the actual purpose of the makefile vs the header file, and that is causing me to lose my mind.\n\nThanks for taking the time to read and any help would be greatly appreciated.\n\nedit:\n\nfor reference,\n\nfileA.o: fileA.c fileA.h\n${CC} ${CFLAGS} -c fileA.c\n\n\nso, since fileA isn't called by anything this would be correct (I do pass address from fileA to both fileB and fileC)?\n\nwould fileB.o: contain fileB.c fileB.h and thats it? or would it have the other headers?"

"MongoDB - How to delete expired documents except last one",
"We're working on audit log solution for one of our projects and would appreciate your help.\n\nWe have media entity which contains media id (numeric), action (string, eg. PUBLISH) and occurred on date with time representing date and time when action happened. \n\nRequirement is to delete logs that are older than 90 days but to keep log with last action on media entity.\n\nWe are using Mongo 3.2 and we need help how to organize our collection since we need to support reads and writes on collection that will contain 200-300 millions of documents.\n\nWe tried several approaches but couldn't figure out a simple way on how to do it. \n\nFirst approach\n\nWe tried to solve it with flat collection with document format:\n\n{\n _id: ObjectId(\"570b3cf65eac4e48e92b4e20\"),\n mediaId: 10000,\n action: \"PUBLISH\",\n occurredOn: ISODate(\"2016-04-04T12:42:07.000Z\")\n}\n\n\nwhere insert is easy but we have problem with deletion of documents.\n\nSecond approach\n\nWe also tried to solve it with documents that contain array of actions and dates:\n\n{\n _id: 10000,\n actions: [\n {\n action:\"PUBLISH\", \n occurredOn: ISODate(\"2016-04-04T12:42:07.000Z\")\n }, \n ...\n ]\n}\n\n\nwhere insert is also easy but again we have problem with deletion of documents.\n\nAny suggestions on how to organize schema for this scenario?"
