need basic r function: firstly order non-decreasing sequence 4 different sequences , order 4 sequences one. im totally green in programing please make simplest way possible. edit1: puting input data required a={3,2,1,2} b={6,7,5,8} c={12,11,9,10} d={65,43,76,13} i first order each sequence, so a={1,2,2,3} b={5,6,7,8} c={9,10,11,12} d={13,43,65,76} and merge it abcd={1,2,2,4,5,6,7,8,9,10,11,12,13,43,65,76} if want function takes vectors a, b, c, , d , input , outputs sorted version of them, can try: sortall <- function(a, b, c, d) sort(c(a, b, c, d)) and can run like: a <- c(1,2,2,3) b <- c(5,6,7,8) c <- c(9,10,11,12) d <- c(13,43,65,76) sortall(a, b, c, d) # [1] 1 2 2 3 5 6 7 8 9 10 11 12 13 43 65 76 if wanted write function combined , sorted number of inputs, try: sortall <- function(...) sort(unlist(list(...))) sortall(a, b, c, d) # [1] 1 2 2 3 5 6 7 8 9 10 11 12 13 43 65 76 sortall(a) # [1] 1 2 2 3

i'm trying iterate vector pairs of chunks (in case it's image represented contiguous bitmap , i'd have access pixels 2 rows @ once). the problem can't .chunks(w).chunks(2) , have create temporary vector in between. is there way purely iterators? (i'm ok if result iterator itself) playpen let input : vec<_> = (0..12).collect(); let tmp : vec<_> = input.chunks(3).collect(); let result : vec<_> = tmp.chunks(2).collect(); [[[0, 1, 2], [3, 4, 5]], [[6, 7, 8], [9, 10, 11]]] this solution create 2 iterators, 1 odd lines , 1 lines. combine 2 using .zip(), give iterator filled pairs: fn main(){ let input : vec<_> = (0..12).collect(); let it1 = input.chunks(3).enumerate().filter_map(|x| if x.0 % 2 == 0 { some(x.1) } else { none }); let it2 = input.chunks(3).enumerate().filter_map(|x| if x.0 % 2 != 0 { some(x.1) } else { none }); let r: vec<_> = it1.zip(it2).collect(); println!("{:?}"...

looking through documentation jsvgcanvas , seems might not able this. however, makes lot of sense possible. how can create jsvgcanvas string variable instead of file ? my idea following: string svg = "svg data"; jframe frame = new jframe(); jsvgcanvas canvas = new jsvgcanvas(); canvas.setcontentsfromstring(svg); frame.add(canvas); frame.setvisible(true); i know create temporary file , set contents of jsvgcanvas file, i'd rather avoid that. perhaps extend file , override methods? note: using jython, think relevant java well, hence i'm using both tags. i'd prefer solution in java, jython solution work yes, can: string parser = xmlresourcedescriptor.getxmlparserclassname(); saxsvgdocumentfactory factory = new saxsvgdocumentfactory(parser); svgdocument document = factory.createsvgdocument("", new bytearrayinputstream(svg.getbytes("utf-8"))); canvas.setsvgdocument(document); this works creating svgdocument via saxsvgdo...

the motivation behind question see whether can make theoretical load balancer more efficient edge-cases first applying regular strategy of nominating particular node route http request (say, via round robin strategy) , "peeking" internal state of system see whether undergoing garbage collection. if so, load balancer avoids node altogether , moves onto next one. in ideal scenario, each node "emit" internal state every few seconds via udp message queue letting load balancer know nodes potentially "radio-active" if they're going through gc (i'm visualizing simple boolean). the question here is: can tweak application tap jvm's internal state , (a) figure out whether we're in gc mode right instant (b) emit result via protocol (udp/http) on wire other entity (like mq or something). there whole bunch of ways monitor , report on vm remotely. well-known protocol, example, snmp. complicated subject. implementation sort of depends o...

i trying analyse packets using python's scapy beginning. upon recent searching, found there module in python named dpkt . module can parse layers of packet, create packets, read .pcap file , write .pcap file. difference found among them is: missing of live packet sniffer in dpkt some of fields need unpacked using struct.unpack in dpkt . is there other differences missing? scapy better performer dpkt . you can create, sniff, modify , send packet using scapy. while dpkt can analyse packets , create them. send them, need raw sockets. as mentioned, scapy can sniff live. can sniff network can read .pcap file using rdpcap method or offline parameter of sniff method. scapy used create packet analyser , injectors. modules can used create specific application specific purpose. there might many other differences also.
