libraries - Exposing a library via zeromq -

-

i wanting know best way expose library via zeromq. say, install machine learning library (mll) on 1 machine, , have zeromq broker running on another. now, if have zeromq client needs call functions within mll, how can via broker.

i wanting know steps need take make work libraries in generic way.

basically need have "listener" picks data zmq , feeds machine-learning backend code, transmits results requestor.

there lot of design choices made, such format use serialize data between client , server (json? yaml? pickle? thrift? ...) , , how encode requests , request options. things considered, pretty straightforward zmq usage.

the problem comes when want more feature-rich, complete, robust, etc. design--things multi-threaded or multi-process servers, multi-machine scalability, secure user / request authentication , authorization, job reporting , dashboard, or job checkpointing. "extras" common "network job scheduler" or "(enterprise) message broker" functions tend come out-of-the-box packages celery or rq.

if don't want go full "message broker middleware" route, might start examining others' designs lightweight zmq-based job brokers, such this 1 jeff knupp.

node.js - Mongoose: Cast to ObjectId failed for value on newly created object after setting the value -

this question has answer here: what's mongoose error cast objectid failed value xxx @ path “_id”? 7 answers even though has been asked many times because entity has no valid objectid field. i came across situation objectid set value can casted objectid still error. the schema: var serviceschema = parammongoose.schema({ servicename:{ type: parammongoose.schema.types.objectid , ref: 'servicenames',required:true } }); pseudo code: servicefromdb=new service({servicename:'some name'}); servicefromdb.servicename='000000000000000000000001'; servicefromdb.save(function(paramerror,paramdata){ if(paramerror){ console.log('but but...',servicefromdb,paramerror) } }); the output of code is: but but... { servicename: 000000000000000000000001, _id: 55079a90286f49280364f78b } { [casterror: cast objectid faile...

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
