i've got function takes node id of graph input , calculate in graph(without altering graph object), saves results on filesystem, code looks this: ... # graph file being loaded g = loadgraph(gfile='data/graph.txt') # list of nodeids being loaded nodeids = loadseeds(sfile='data/seeds.txt') import multiprocessing mp # parallel part of code print ("entering parallel part ..") num_workers = mp.cpu_count() # 4 on machine p = mp.pool(num_workers) # _myparallelfunction(nodeid) {calculate nodeid in g , save file} p.map(_myparallelfunction, nodeids) p.close() ... the problem when load graph python takes lots of memory(about 2g, it's big graph thousands of nodes actually), when starts go parallel part of code(the parallel map function execution) seems every process given separate copy of g , run out of memory on machine(it's got 6g ram , 3g swap), wanted see there way give each process same copy of g memory hold 1 copy of required? suggestions apprec...

does generic list guarantee order of items when adding , iterating values? if so, in definition of type or assumption on usual behavior? updated: it looks order kept now; there no trace of in official documentation, therefore assume might change in future , not in definition of list. is there simple collection guarantees order? (excluding stack/queue specialized other uses) it looks it's safe assumption. although, critical applications (defence/finance), might worth using linkedlist or sub-classing list make future-proof in case new framework changes implementation. the getenumerator return first element in list, there no written guarantee next element must second in list.

i tried around time, not able find answer problem. writing java program used read , update firmware of hid device. using purehid java libraries communicate device , working fine. the problem experiencing, , not able fix, concerns synchronization of events. i give example. when copying firmware installed on device, using following method dev.setoutputreport((byte) 0, packet_to_send, buffer_size); the answer unit come in form of event received listener attached device manager, namely following listener invoked oninputreport() /* happen */ my problem sometimes, because of concurrent writing/listening invocation, program freeze, without exception nor error signaled. to fix problem, tried implement simple lock mechanism, lock being released when reply received; unfortunately may happen reply packet lost blocking me in deadlock. one possible solution though use timer release lock automatically after x milliseconds if not released (the reply arrive within 10ms or not arriv...

suppose have c# class has multiple properties this: private bool _var1dirty = true; private double? _var1; public double? var1 { { if (_var1dirty) { _var1 = method_var1(); _var1dirty = false; } return _var1; } } and differences between each of these properties be: the type of return var (in case double? , int , string , etc) the method call - method_var1() (each property have different one) is there way write custom class? something along lines of: public class prop { public delegate t func(); private bool _dirty = true; private t _val; public t val { { if (_dirty) { _val = func; _dirty = false; } return _val; } } } and pass the: return type t method func (ps - know won't compile / dead wrong, wanted give idea of i'm looking for) any / guidance apprecia...

is possible create array of system objects in matlab , mex c code? for example, in c++ can create vector myclass user defined class. possible create equivalent thing in matlab using system objects , build c code? creating ordinary arrays of system objects not supported. can place them in cell arrays. code generation c code or mex file not support array of classes. if can give more detail on trying array of objects can try see whether there alternate approaches solve problem.

what dangers of using implicit string conversion operator in custom string class? class mystring { public: ... inline operator string() const { return str; } private: std::string str; }; the main "danger" of implicit conversion mostly: might unexpected conversion. if string class can logically used std::string, not think there problem.

transloadit uses temporary url our files. need upload important files rackspace cloud private container.. have setup seems that, after uploading, users can read assembly result js. rackspace urls can read but, because private container, rackspace url (and ssl_url) inaccessible user. the problem that, there transloadit temporary url contains file. is there anyway disable temporary url can guarantee our users files not publicly accessible ? if not, can flag implemented can use on our template? best fa we use temporary url machine-to-machine communication of files. realize not ideal, , implement flag auto-deletes temporary files of assembly after execution. in future move amazon efs remove need temporary urls entirely. kind regards, tim co-founder transloadit @tim_kos

i aimed open multiple files (one one, using loop in bash terminal) , modify using plink (a programme) , later on, python function. following codes: for in {1..10}; plink --cow --noweb --lfile $i --extract extract1.snp --recode --out 1$i python -c 'import file_convert;file_convert.convert_tree_mix("1$i.map","tmp$i")' done but, expected, python not read , not open "11.map", did not replace "$i" 1. how can modify code python function, in combination loop, open different file each time based on value of "i" you need include whole python code inside double quotes, $1 inside python code expand. $1 in shell refers first parameter. python -c "import file_convert;file_convert.convert_tree_mix(\"1$i.map\",\"tmp$i\")"

i working in safari 8.0.4 local-storage variables. can see values in web inspector, select/copy , delete them. if try edit them, changes not kept after page refresh. input field behaves little strangely, can't seem deselect way apart hitting escape (return key or clicking outside nothing). is known bug, , there way manually edit local storage value in safari? i unsuccessful directly editing within resource inspector, did change local storage values via safari's javascript console. (just below resource inspector) use command this: localstorage.setitem(key, value) it less convenient direct editing, work.

this question has answer here: reference - symbol mean in php? 15 answers i not know if question have been asked before. but wondering when should use <> on != i know if result equal not know difference between 2 operators if (1 != 0) { // true } and if (1 <> 0) { // true } please explain me differences. they exactly same, manual: $a != $b not equal true if $a not equal $b after type juggling. $a <> $b not equal true if $a not equal $b after type juggling.

i'm familiarising myself both flux architecture, , reflux - simpler version, without dispatcher - use reactjs. in full flux, sounds actions have (or @ least, can made have) definite , non-trivial purpose: can used update external services (eg. save data server via api), described in question: should flux stores, or actions (or both) touch external services? however, in reflux, actions dumb message parsers. question is, purpose serve? why have them @ all? bad things happen if views/components called methods on store directly? i'm convert little app flux reflux, , looks i'll moving logic in actions on store. seems me actions in reflux nothing other act useless middleman between component , store. missing? besides ability listen action in number of stores pointed out in op comments: reflux actions can touch apis , such, placing in preemit action hook example. typically you'd create async action, add async stuff in preemit hook, , call "completed...
