i've installed crate db on virtual machine ubuntu (xenial). since want connect both vm , windows host, i've tried set vm's ip on both params in crate.yml: network.host network.publish_host the rest of parameters can see in crate.yml but won't trick (i err_connection_timed_out error when try connect "my_vms_ip:4200" windows host pc) , can't find way around on crate.io nor on google. would of have idea? thanks lot nb: i'm running crate 2.0.7

i'm trying play square waves generated using scipy pyaudio error typeerror: len() of unsized object which kind of strange because square wave object should have size, right? rate = 48000 p = pyaudio.pyaudio() stream = p.open(format = pyaudio.paint16, channels = 2, rate = rate, output = true) # ... inside loop wav = signal.square(2*math.pi*freq*t) wav = wav.astype(np.int16) stream.write(wav) # crash here the crash happens on first iteration of loop, suppose loop not problem. i same error. however, omitting information, assume these imports: import pyaudio import math import numpy np scipy import signal and that freq = 440 it looks variable iterating t , it's scalar. might have reasons this, don't think how scipy.signal meant work. if use vector t instead: t = np.linspace(0, 2) then signal.square(...) , stream.write(wav.astype(np.int16)) work without problems.

i'm going implement customized map of pokemen go or waze style. have searched much, can't find right answers. can use mapbox that? give me examples? i'm not sure if it's possible , easy? help me! thanks maybe can have on apple base class mkmapview . provide best user experience , better flexibility. if read mapbox , googlemaps docs understand provide overlay of mkmapview. these providers usefull if want use sdk specific reason (like google direction api) or if want have map quickly. if need more specific behaviours limited scope. example, custom clusters more tricky google maps (google-maps-ios-utils doesn't provide enough flexibility) mkmapview.

i using ruby sqlite3 (1.13.11) on macos (ruby 2.0.0-p247) create few databases application. need set pragmas, not sure doing right thing. set pragma synchronous = off db = sqlite3::database.new("test.db") db.synchronous 2 db.synchronous = 0 db.synchronous 0 this seems work, when open test.db db browser sqlite , synchronous still set full . i have tried db.execute("pragma synchronous = off") with same result. is synchronous associated connection? case pragmas ?

i trying fit curve set of data points: def func(x, a, b, c): return * np.log(-b * x) + c #return * np.exp(-b * x) + c xdata = np.array(x) ydata = np.array(y) popt, pcov = curve_fit(func, xdata, ydata) plt.scatter(xdata, ydata, label='data') plt.plot(xdata, func(xdata, *popt), 'r', label='fit') plt.xlabel('x') plt.ylabel('y') plt.legend() plt.show() the data set contains 50 points. 2 of them outliers. generated 2 plots of data , fitted curve: first 1 contains outliers , other plot excludes outliers: however, both curve fits contain many nan values, why red fitted line small. got values of 1 each variable in popt . tried both log , exp fits seen in code above are there better curves exponential or log fits can try? edit: definition of func comes before curve_fit call

i'm writing own shared library. want use global variable in code. how can make happen ? i.e. write class. class mywork { build() { // here want use global docker(which docker-plugin) docker.dosomething { } } } enable library in 'global pipeline libraries' (i add library 'pipeline-shared-lib') create shared-library (with necessary structure) src/net/kukinet/utils.groovy package net.kukinet; def myvar = 1 def sayhello() { print ('hello') } create pipeline job , create object jenkinsjob.groovy #!groovy // need enabled in jenkins configuration ( in: manage jenkins) @library('pipeline-shared-lib') import net.kukinet.* node (){ u = new net.kukinet.utils(); stage('preperations') { print(u.myvar) u.sayhello() } }

i encountered strange problem: try turn string float , str this: str(float(tmp[1])/100) # tmp[1] contain str but throw out valueerror: invalid literal float(): "320" so try this: try: line_split[list_index] = str(float(tmp[1])/100) except: print >> sys.stderr, repr(tmp[1]) also, same error, , print '"320"' any help? thanks! the issue might sort of non-printing character that's present in value using. looks you're using python 2.x, in case can check them this: print repr(tmp[1]) you'll see in there that's escaped in form \x00. these non-printing characters don't show when print directly console, presence enough negatively impact parsing of string value float.

i'm newbie kafka. when read documentation of kafka, saw kafka performing because of sequential disk access . but how possible? in java(or else), if use file i/o, os handle appropriately. however, can't know if os store files want store in multiple sectors or in contiguous sectors. so, kafka cannot sequential disk access occurs in opinion. am true or not? kafka not always access disk sequentially things make more disk access often sequential. kafka messages stored in larger segment files (1gb each default) , since kafka messages not deleted when consumed (like in other message brokers) kafka not end creating fragmented filesystem on time continuously creating , deleting many variable length files. instead creates segment files , appends file until reaches 1gb (a configurable limit). when messages in segment expire delete entire 1gb segment. means these 1gb sections of disk laid out contiguous blocks. recommended best practice keep these kafka commit log files ...

i calculate how long async function ( async / await ) taking in javascript. one do: const asyncfunc = async function () {}; const before = date.now(); asyncfunc().then(() => { const after = date.now(); console.log(after - before); }); however, not work, because promises callbacks run in new microtask. i.e. between end of asyncfunc() , beginning of then(() => {}) , queued microtask fired first, , execution time taken account. e.g.: const asyncfunc = async function () {}; const slowsyncfunc = function () { (let = 1; < 10 ** 9; i++) {} }; process.nexttick(slowsyncfunc); const before = date.now(); asyncfunc().then(() => { const after = date.now(); console.log(after - before); }); this prints 1739 on machine, i.e. 2 seconds, because waits slowsyncfunc() complete, wrong. note not want modify body of asyncfunc , need instrument many async functions without burden of modifying each of them. otherwise add date.now() statement @ beginning , end of ...
