does know how docker decides nic work docker0 network? have node 2 interfaces (eth0 , ens34), however, requests go through eth0 forwarded container. when vm provisioned , docker installed, started silly test: created centos vm, installed netcat on , committed image. started daemon container listening on port 8080. used: docker -it -p 8080:8080 --name nc-server nc-server nc -vv -l 8080 so tried connect container listening on port 8080 node in same network (in same ip address interface ens34). did not work. whereas when sent request machine ip address eth0, saw reaction in container (the communication worked). "tailing" output with: docker logs -ft nc-server my conclusion experiment: there's mysterious relationship between eth0 (primary nic) , docker0, , requests sent ens34 (10. ) interface never forwarded veth / docker0 interfaces, requests go through eth0 (9.*). why's that? also, know can make work if use --net=host, don't want use that... doesn

what's difference between windows store apps (introduced in windows 8) , universal windows platform apps (introduced in windows 10). how share development point of view. if spent time learning how build windows store apps can knowledge transferred uwp development? i add more previous answers. the main , important thing universal windows 10 apps compiled native code (with .net native compiler). from developer point of view there difference between debug , release. when debugging uwp app in visual studio running intermediate language (with jit/just-in-time compilation machine code) means fast compilation , deployment. if decide build app in release configuration - app utilizes .net native toolchain. takes more time compile, optimized lot more run time performance. to read more please see below article: https://blogs.windows.com/buildingapps/2015/08/20/net-native-what-it-means-for-universal-windows-platform-uwp-developers/ the second important thing windows 10

we have multi-module maven project, looks this: parent-module -> dao-module-1 -> dao-module-2 -> algorithms-module -> jaxb-module -> jaxrs-module -> webapp-module i have code in algorithms-module needs write image webapp-module. way, end-users can point browsers url in webapp-module , retrieve image. without hardcoding path parent-module, what's best way path parent-module? there default property in maven has value? if not, setting property in pom files solution? i believe can use ./ @ beginning of string path if wan keep relative. alternately, use system.getproperty("user.dir") absolute path parent project folder.

i'm trying construct simple tilemap thingy, part of larger project, , 1 of solutions came out use function so: def tile((value, x, y)): if value == 1: pygame.draw.rect(screen, (0, 0, 0) (x, y, 64, 64), 0) the idea being set level out list of tuples contain value denotes tile drawn there, , coordinates of tile. this, of course, doesn't work since can't use tuple argument. my solution instead values out of tuple in list: def tile(value, x, y): if value == 1: pygame.draw.rect(screen, (0, 0, 0) (x, y, 64, 64), 0) level = [(1, 0, 0), (rest of list)] tile(level[0[0]], level[0[1]], level[0[2]]) which didn't work, , gave me traceback (most recent call last): tile(level[0[0]], level[0[1]], level[0[2]]) typeerror: 'int' object has no attribute '__getitem__' does have workaround this? way can feed tuple function series of arguments? or using idiosyncratic method won't ever work ever? i'm guessing due blinding in
