i have problem read/write data usb mass storage device, 'device or resource busy' error below command: ioctl(usbfd, usbdevfs_claiminterface, &interface_num) so need release interface before. don't know how can pass interface_num correctly command: ioctl(usbfd, usbdevfs_releaseinterface, &interface_num), if it's not defined, there function found interface number. please me! thanks. the documentation states: usbdevfs_releaseinterface this used release claim usbfs made on interface, either implicitly or because of usbdevfs_claiminterface call, before file descriptor closed. ioctl parameter integer holding number of interface ( binterfacenumber descriptor); file modification time not updated request. but seems here "parameter integer" still means pointer integer should passed, you're showing. if have descriptor, can find interface number.

let's have in module: resolve: { user: function(userloader){ return new userloader($stateparams.userid); } } controller.. as can see, i've not injected $stateparams , hence fail load controller , view. why console not giving errors on resolve everywhere else? can pain debug if have logic in resolve. possible "turn on" console on resolve somehow? from documentation : $statechangeerror - fired when error occurs during transition. it's important note if have errors in resolve functions (javascript errors, non-existent services, etc) not throw traditionally. must listen $statechangeerror event catch errors. use event.preventdefault() prevent $urlrouter reverting url previous valid location (in case of url navigation). you must listen on '$statechangeerror' event $rootscope.$on('$statechangeerror', function(event, tostate, toparams, fromstate, fromparams, error){ // error occured, $log.error(e

so following code function: "eqn" converts string: "d" mathematical expression, list of integers , operators according reverse polish notation, "add", "subtract", "multiply" , "divide" represent +, -, * , / respectively. there "negate" operator takes positive integer , turns negative integer. example inputs , outputs: eqn("10 5 add") should produce output of [10, 5 , "add"] eqn("5 6 add 2 negate divide") should produce output of [5, 6, "add", -2, "divide"] with negative function though, if not used correctly (not after number) function should return index number of first incorrect "negate". for example: eqn("negate 2 add 2") should produce output of 0 eqn("2 4 add negate") should produce output of 3 def eqn(d): extrac = [] e in eqnstr.split(): if len(e) == 0: continue try: extrac.append(int(e)) continue

is there way make tkinter window unclickable? meaning input should caught handler redirected whatever window behind it? if not in tkinter, there way in pyqt or wxpython? goal have handler catch keyboard events while still letting them input windows behind. don't need catch clicks nice have if possible. my current plan: a tkinter window geometry of 10000x10000, alpha of 0 , topmost set true. frame catch keyboard & mouse events , when entered frame catch it, hide tkinter window using apple script function run terminal osascript, use autopy simulate whatever entered such click/keyboard event , unhide window again. sound viable? when have time test out idea , post if works. i'm thinking computation speed issue here.

i have 2 python files: 'old.py' , 'new.py'. execute 'new.py' 'old.py' using execfile("new.py"). however, rather waiting 'new.py' finish program before moving next line in 'old.py', both scripts continue independently (i.e., 'old.py' moves line after execfile('new.py') command immediately. for instance, if 'new.py' takes 48 seconds complete program in entirety, , 'old.py' reads: execfile("new.py") print 2+2 i "4" printed immediately, rather 48 seconds later. how recommend doing this? thank sharing knowledge , expertise. you want utilize subprocess.popen . open process in separate process. # old.py - make sure it's chmod +x #!/usr/bin/python import time time.sleep(48) # new.py #!/usr/bin/python import subprocess subprocess.popen(["./old.py"]) print(2+2) >>> python new.py 4 >>> ps pid tty time cmd 2

according https://en.wikipedia.org/wiki/comparison_of_java_and_c%2b%2b c++ supports unsigned integers while java not, advantages of that? a major difference c , c++ used low-level programming bits shifted , masked; unsigned integer behaves naturally there. and c++ there c compatibility. when c conceived larger value range may have been reason too, when ints 16 bit. a minor point (for c) may efficiency 1 wanted support unsigned chars on architectures architecture default, , there expand concept of unsigned integer types in order orthogonal; although find argument weak.

i'm getting started elasticsearch , 1 of main use cases i've seen it's scalability searches on large data sets, besides when want use on creating sql queries traditional rdms? there 2 primary elasticsearch use cases: text search you want elasticsearch when you're doing lot of text search, traditional rdbms databases not performing (poor configuration, acts black-box, poor performance). elasticsearch highly customizable, extendable through plugins. can build robust search without knowledge quite fast. logging , analysis another edge case lot people use elasticsearch store logs various sources (to centralize them), can analyze them , make sense out of it. in case, kibana becomes handy. lets connect elasticsearch cluster , create visualisations straight away. instance, loggly built using elasticsearch , kibana. keep in mind, wouldn't want use elasticsearch primary data storage. reasons here: how reliable elasticsearch primary datastore again

this question has answer here: how can pass class member function callback? 8 answers i don't know how word this, i'll try best explain in code: typedef void( *examplefn )( pvoid p1, pvoid p2, pvoid p3 ); struct example { void examplefunction( pvoid p1, pvoid p2, pvoid p3 ) { // example's members } }; example example; examplefn examplefn = example.examplefunction; so, error: error c2440 '=': cannot convert 'void (__thiscall example::* )(pvoid,pvoid,pvoid)' 'examplefn' i understand problem, example::examplefunction __thiscall , examplefn not, how can go this? how have example object examplefn-like function in can use object's members? you need define youre function-pointer correctly. it's member-function pointer, needs this: typedef void(example::*examplefn )( pvoid p1, pvoid p2, pv

this question has answer here: es6 - declare prototype method on class import statement 3 answers in es5 can setting prototype existing function how go es6 classes //// es5 function existingfn = function () { // }; function myclass () { // constructor stuff }; myclass.prototype.newfn = function () { // … }; myclass.prototype.existingfn = existingfn; //// es6 class myclass { constructor() {} newfn() { // … } // ??????? // existingfn = existingfn // ??????? } ecma-script 6 class syntax syntactic sugar on regular prototype system: class { } // still possible! a.prototype.dostuff = function() { }; var existingfn = function() {}; a.prototype.existingfn = existingfn; var instance = new a(); instance.existingfn();

some background information @ first: i'm analysing load on oracle database .net application make use of nservicebus. we've observed high redo logs activity when running application , hence - high amount of archivelog (we've got database in archivelog mode). we've used toad logminer find out causes it, unfortunately many of operations of type unsupported. i've assume it's because of using securefile type of lob. i've digged database logminer view: v$logmnr_contents see there lot more columns in toad's logminer. what need size of each operation in redo. here's query far: select timestamp, rbabyte, seg_owner, seg_name, table_name, seg_type, seg_type_name, table_space, row_id, operation, sql_redo v$logmnr_contents 1 = 1 , operation = 'unsupported' i'm not sure if rbabyte correct value use or maybe calculation more complicated, me looks record size including lob

my problem this, have query one: match (a:a), (a)-[:relation]-(b:b) return {name: a.name, products: collect(distinct {productname: b.name, ident: b.identifier}) } and can't find way filter result of 'products', example, having rows productname = 'pname1' contained in array 'products': row1: {name: 'name', products:[{name: 'pname1', ident: 'id1'}, {name: 'pname3', ident: 'id3'}] } row2: {name: 'name2', products:[{name: 'pname2', ident: 'id2'}] } the example above return row1 thank in advance attention the with clause interesting thing query can splitted , query results @ point can saved variables. so, first row, query match (a:a), (a)-[:relation]-(b:b) a, collect(distinct {productname: b.name, ident: b.identifier}) products {productname: "pname1", ident:"id1"} in products return {name: a.name, products: products} edit: the solution above compar

i have found mysterious white space on right side underneath toolbar next picture have should extend way edge. if nav bar extends far. didnt notice need scroll on right see it. have tried playing around width on photo , nav bar. same thing appears on footer, seems in alignment photo leads me believe navbar on extending. have tried deleteing few things in navbar but, nothing seems fix problem. html: <div class="row"> <nav class="navbar navbar-custom" role="navigation"> <div class="navbar-header-xs"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#collapse"> <span class="sr-only">toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar

when base address of array stored in register, understanding 1 not want adjust register. trying understand when principle valid. valid practice when dealing saved registers or saved registers , argument registers, too? below example working involves converting simple c code mips instruction. attempted solution in 2 ways. in first solution, increment registers holding base address of array , array b. thoughts given base address registers, $a0 , $a1, argument registers, not saved registers. thought, perhaps, wouldn't matter adjusted. in second solution, stored base address of each array temporary registers , manipulated instead. i did find solutions online particular example, i'm trying understand basis each instruction, rather following procedural solution. advice on best mips practice appreciated! # c code: (i=0; i<=100; i=i+1) { a[i] = b[i] + c; } # $a0 = base address of array # $a1 = base address of array b # $s0 = c # attempted solution # 1 l
