i reading static flow control , came across riwo concept. can explain simple terminology , perhaps code sample? this related error "illegal forward reference". relevant link . after going through material , discussing couple of guys offline found out following information. when java class getting executed there few steps jvm performs few steps sequentially. identify static members top bottom. executes static variables assignments , static blocks top bottom. executes main method. during these phases there 1 such state called riwo(read indirectly write only) static variable. during riwo variable cannot accessed directly reference. instead need use indirect way call variables. for example: class riwo { static int = 10; static { system.out.println(i); } } in above case output 10. class riwo { static int = 10; static { m1(); system.out.println("block1"); } public static void main(string... args) { m1(); system.

our product generates minidump files in case goes wrong. run symbol server storing , accessing debug symbols of our builds such proper stack traces out of dump files. since our product runs on other operating systems (in particular linux , os x), started @ google breakpad . appears use minidumps, , pdb files storage. however, wonder: (how) can migrate existing symbol server google breakpad don't lose existing symbols? imagine other people did same move already, maybe there's common approach this? you have few options: run dump_syms (this tool processed pdbs text-based breakpad's .sym format, comes breakpad) on pdbs in server , upload them breakpad server (there couple options, use socorro). need keep running on new symbols builds care about. request symbols server needed stack_walker when processing incoming crash (we haven't done that) periodically missing symbols in last number of crashes, see if on symbol server, run them through dump_syms, up

if have data types identification , person, how use them? type identification = name of string | ss of int * int;; type person = personal_info of identification;; how make person type has identification? how construct variable these types in it..? something this: person1 = personal_info (name = "cody") (ss = (231,4534));; val person1 : person = ..... your identification type specifies either name or social security number. looks me want have both of them. should use record type: type ident = { name: string; ss: int * int } since person type has 1 variant, redundant (not couldn't useful in cases). here value of type ident : { name = "cody"; ss = (231, 4534) } if want use person type, this: type person = pi of ident a value of type this: pi { name = "cody"; ss = (231, 4534) }

is possible filter queryset in such way retrieve users don't have matching object every date in range? for example, have shift model includes foreignkey field pointing employee object , date_requested datefield indicating date of shift. i've created following query grabbing user doesn't have shift between, say, 2015-07-19 , 2015-07-25 : employee.objects.all().exclude( shift__date_requested__gte=datetime.date(2015, 7, 19), shift__date_requested__lte=datetime.date(2015, 7, 25)) unfortunately queryset doesn't catch user has specified shifts 07/19 through 07/24, not 1 07/25. possible further refine query say, "the number of shifts associated user between 2015-07-19 , 2015-07-25 (inclusive) must equal number of days within time frame? edit: here's code ran according 1 of answers below: first, dataset showing employee #10 has shift on every day between 7/19 7/25. should lead them being filtered out: and filtering code e = employe

i running genghisapp - gem mongo management. when run it gives me warning native bson extension not loaded , suggest run gem install bson_ext . i have installed rbenv , have gems such genghisapp installed in ~/.gem on path , loads fine. my first attempt run gem install bson_ext after restarting mongo/shell had no effect - message still there. i suspected not genghisapp message mongo 1 thought might need install sudo. resulted in breaking rbenv install due permissions being set root/whatever because still using local rbenv gem. what proper way solve this? should find osx gem , call full path install or need specify else? the issue because a) version of mongo , bson_ext must match , b) there must not other bson_ext version installed. the comments on issue helped me solved issue. run: gem list | grep -w 'bson\|bson_ext\|mongo' print out versions. should like: bson (1.9.2) bson_ext (1.9.2) mongo (1.9.2) and not like: bson (2.3.0, 1.10.2, 1.9.2)

if (°[0-5]) matches °4 and ((°[0-5][0-9])) matches °44 why this ((°[0-5])|(°[0-5][0-9])) match °4 not °44? because when use logical or in regex regex engine returns first match when find match first part of regex (here °[0-5] ), , in case since °[0-5] match °4 in °44 returns °4 , doesn't continue match other case (here °[0-5][0-9] ): ((°[0-5])|(°[0-5][0-9])) a|b, , b can arbitrary res, creates regular expression match either or b. arbitrary number of res can separated '|' in way. can used inside groups (see below) well. as target string scanned, res separated '|' tried left right. when 1 pattern matches, branch accepted. means once matches, b not tested further, if produce longer overall match. in other words, '|' operator never greedy. match literal '|', use \|, or enclose inside character class, in [|].

we have application connects server , sends position every 15 seconds. our client has asked "upgrade" our current tcp/ip connection websocket. reason heard used less bandwidth , wants diminish 15 seconds 1 second. (not public application battery drain not problem) i have done research , many websockets vs http comparisons 2 or 3 comparisons of websocket vs tcp/ip. i've found out : websockets same tcp/ip tcp/ip works on lower layer websockets. websockets might use less bandwidth because protocol might more efficient our current protocol. websockets use more resources on server side. my question is: worth change our existing code , make use of websockets instead of ol' tcp/ip sockets? as appear know already, websocket built on top of tcp/ip connection. it's specific protocol built on top of tcp. my question is: worth change our existing code , make use of websockets instead of ol' tcp/ip sockets? if code works tcp socket , don

i have binary number, example 10000111000011 , , want split groups of consecutive 1s , 0s, 1 0000 111 0000 11 . i thought that's great opportunity use look-arounds: regex uses positive look-behind digit (which captures later backreferencing), negative look-ahead same digit (using backreference), should split whenever digit followed digit not same. use strict; use warnings; use feature 'say'; $bin_string = '10000111000011'; @groups = split /(?<=(\d))(?!\g1)/, $bin_string; "@groups"; however, results in 1 1 0000 0 111 1 0000 0 11 1 somehow, captured digit inserted @ every split. did go wrong? here small fix code: my @groups = split /(?<=0(?!0)|1(?!1))/, $bin_string; the problem experience when using split captured texts output in resulting array. so, solution rid of capturing group. since have 0 or 1 in input, pretty easy alternation , lookahead making sure digits changed. see demo
