Git merge commits selectively -

-
i have question git i've never had do, learn! in project branched off master while back; rewrite of entire codebase, let's call rewrite . in time have been working on rewrite have made , deployed significant changes master . rewrite coming close, want bring speed changes made on master since started branch. usually git checkout rewrite && git rebase master , solve conflicts arise, time around can guarantee every commit have conflict since codebase entirely different. tl;dr wondering how go taking each commit on master , one-by-one merging them rewrite , @ own pace , possibly out of order if need be. you can use git cherry-pick command put specific commit branch. you can use gitk --all see commits , select commit want cherry-pick interactively branch.

i want know how create plot of stepwise function in gnuplot. function want plot includes operations cost several distance range , multiple products. instance, if distance 0-300 km product 1 cost 1.05 $/km , product 2, 0.86 $/km. when distance increases, cost each product decrease. i have defined 1 function each product , plot them functions together: gnuplot> f(x)=x<=300 ? 1.05 : x<=650 ? 0.65 : x<=1300 ? 0.46 : x<=1950 ? 0.4 : x<=3250 ? 0.31 : 0.22 gnuplot> x<=300 ? 0.86 : x<=650 ? 0.53 : x<=1300 ? 0.38: x<=1950 ? 0.32 : x<=3250 ? 0.24 : 0.19 gnuplot> plot [0:5000][0:3] f(x), g(x) there 1 problem: can not remove vertical lines. idea? thanks help there 2 approaches can take. best approach use datafile, can use functions, although more difficult. datafile approach you going have trouble doing function, because going vertical lines. datafile gives little better control, , allows mark end points of pieces of piecewise ...

jenkins - Build Flow Plugin While Loop -

-
i'm trying setup build flow plugin run job forever until cancel build flow. while(true){} works, absolutely isn't safe, if mess parameters, it'll cause flow enter endless loop , become uncancellable without restart of jenkins. is there safe way this: while(true){ignore(failure){ build(project) build(anotherproject) }} so clicking x button cancel build flow properly? alternately, there better way build multiple projects forever single project, waiting each project complete before moving on next 1 in line , looping first? solution: if select workspace checkbox above build flow, call post build actions, can recall project. if don't select workspace button, post build actions not fire off.

Use Julia to perform computations on a webpage -

i wondering if possible use julia perform computations on webpage in automated way. for example suppose have 3x3 html form in input numbers. these form square matrix a, , can find eigenvalues in julia pretty straightforward. use julia make computation , return results. in understanding (which limited in direction) guess process should like: collect data entered in form send data machine has julia installed run julia code given data , store result send result webpage , show it. do think possible? (i've seen stuff using httpserver allows computation browser, i'm not sure right thing use) if yes, things need into? have examples of such implementations of web calculations? if using or can use node.js, can use node-julia . has limitations, should work fine this. coincidentally, done putting example this. rough mockup available here , uses express serve pages , plotly display results (among other node modules). another option write server in julia ...
