how can create sorted map compares value's bean's field. map key integer , value car. i'd compare car's name it's can contains no letters. something this: (it's not work, bad example) comparator<car> carnamecomparator = new comparator<car>() { @override public int compare(car c1, car c2) { return c1.getname().comparetoignorecase(c2.getname()); } }; sortedmap<integer,car> carmap = new treemap<>(carnamecomparator); second try: map<integer, car> carmap = new hashmap<>(); carmap.put(1, car1); carmap.put(2, car2); map<integer, car> sortedbyvalue = carmap.entryset().stream() .sorted(map.entry.<integer, car> comparingbyvalue(carnamecomparator)) .collect(collectors.tomap(map.entry::getkey, map.entry::getvalue, (e1, e2) -> e1, linkedhashmap::new)); sortedbyvalue.foreach((k,c)->system.out.println("key : " + k + " value : " + c.getname())); m

what if have array urls want webpage redirect to, how can loop array forever, unless close browser? let’s have var urls = ['/news/1', 'news/2', 'news/3', '/update/1', '/news4', 'news/5', 'news/6', 'update/2'] etc…. i have single html template changes content of elements inside based database records. want redirect page (same html template) following urls every 10 minutes. i have: <script> var timer = settimeout(function() { window.location=‘/news/1' }, 10000); // redirect once news/1 after 10seconds. </script> how can proper loop here on url array? thank reading! you can check on url are, update index, , start timeout. put in every page: var urls = ['/news/1', '/news/2', '/news/3', '/update/1', '/news4', '/news/5', '/news/6', '/update/2'], currentpath = window.location.pathname, curre

our company has 5000 users. each user has office 365 corporate email account , majority of these users use outlook web access (owa) read/send emails. out of 5000 users have 2000 users grouped category called sp (sales people). unfortunately, these 2000 users not computer savvy , reluctant use corporate email account. they reluctant because not accustomed using owa. instead, use own personal email accounts such gmail, yahoo, hotmail, etc... the problem send them important corporate messages emails since open owa, these emails never read or acknowledge. a company policy not allow send corporate messages directly personal email accounts. information must stay in house. we came following solution: each time receive email in corporate account, email notification automatically sent personal email account quick message saying hey...you’ve got new corporate email, please come , check out. exchange admin center (office 365) our initial goal create new rule inside m

i use autofac in console application. first usage. before using in asp.net mvc only. in mvc project can setup autofac in global.asax, inject iservice controller , can more , less works. in console application below: internal class program { private static icontainer container { get; set;} private static void main(string[] args) { container = container.configure(); // here have necessary objects set // can use in main method as: using (var scope = container.beginlifetimescope()) { scope.resolve<isomething>(); } } } as can see usage of simple in main method. how using in external class? let create class cat, , inside use autofac. should pass contructor object container class program? e.g.: cat cat = new cat(program.container, "molly"); or maybe should create icontainer inside cat class? what best solution? only console application needs know autofac, otherwise you're fall

it's can run npm scripts not project root subfolders. however, constraint can't tell current working path ($pwd). let's there's command this: "scripts": { ... "pwd": "echo $pwd" } if run npm run pwd within subfolder of project root (e.g, $project_root/src/nested/dir ), instead of printing out current path $project_root/src/nested/dir , gives $project_root back. there way tell npm scripts use current working directory instead of resolving package.json resides? want pull yeoman generator existing project , use through npm scripts can use shared knowledge (e.g, npm run generator ) instead of learning yeoman specific (e.g npm yo -g; yo generator ). generator generates files based on current working path, while npm scripts resolves project root, can't use generator intend used. one known solution through env variable injection. for example: declare variable in command line: cwd="$(pwd)" npm run pw

checking play documentation found can automate json de/serizalization following code: implicit val addresswrites = json.writes[address] implicit val addressreads = json.reads[address] a friend told me add on companion object, should add 1 companion obj each class add json config? couldn't add models in 1 place or use annotations on each class in java? and general config like: implicit val config = jsonconfiguration(snakecase) where add that? regarding put serializer/deserializer implicits, have few suggestions: declare everytime need use it add companion object , implicit available when import data class declare in single jsonserializers object , import whenever need use it. using companion object makes easy remember import make implicits available when needed (typically in controller class) , "encapsulates" code related model in single file. having single jsonserializers object has advantage of making possible have serializers availabl

if i'm writing python program execute other 2 executables(c++) in producer , consumer manner, right lib do? asyncio? multiprocessing? the main execution thread or process is: monitoring status of producer , consumer processes. if 1 of them fails, terminate other. if ctrl-c received, terminate both of them if both of them finishes, exit , report success. the producer: keep generating data temp file. (that temp file might fifo os.mkfifo()?) the consumer: keep consuming temp file both producer , consumer cpu intensive, , need run in parallel. ideally intermediate temp file doesn't need touch real storage , stay in memory. otherwise performance big concern since temp file of size 10gb or so.

actually, have find no of text lines in given image e.g. if having 2 images from pil import imagegrab img1=imagegrab.grab([0,0,200,80]) img2=imagegrab.grab([300,0,500,80]) first 1 img1 , second 1 img2 how can input img1 , output 5 , if input img2 output 4 i.e. no of text lines in image if want without ocr-ing text, typical approach, determine each line in image if has 1 or more 1 color. the lines 1 color can assumed background transition more 1 color single color "bottom" line of text row. count transitions , you'll have number of lines of text in image. this assumes: characters of 1 line no extend bottom of cell drawn in (that mean there might never empty line if top line has g , bottom 1 f - or similar configurations) there text , not pictures (as in samples).
