this related another question here . i want create series of cron scripts, cron scripts can have 1 instance each. need implement lock files each script. decided create abstract cron class create lockfile on __init__ , destroy on __del__ . approach has proven incorrect getting unpredictable results __del__ method. it has been requested open new question asking how implement this. best approach here? 1 cron script check email, checks database, , forth. my reasoning behind using cron don't trust myself build monolithic daemon 1 script. can't afford have entire daemon breakdown if 1 unrelated part stops working. perhaps unwarranted fear proper implementation?

using stock android examples httpurlconnection , httpresponsecache, have created bare bones app calls 2 urls, twice. first 1 without content-length , second 1 content-length . i can see in charles endpoint without content-length not cached. removed content-length caching url , confirmed prevents caching well. unfortunately there no way have gzipping , content-length in restify according gzip plugin docs . is there way force httpresponsecache cache url when content-length missing? logic behind not caching urls without content-length? (ios caches without content-length) *using volly or restify last resort due large existing codebase. ended moving retrofit had no issues caching without content-length header.

i tried attack problem using classical join operation: have table posts , table followings, given user_id retrieve followings , posts of followings joining both tables. until here it's fine. since it's timeline, need establish number of posts retrieve, let's 30. there button retrieve previous 30 posts , on, means need retrieve timeline in chunks of 30 posts. the problems comes when thinking efficiency. i'm not expert on dbs remember on mysql can (i don't know how it's in postgresql though): select * [... join ...] limit 0,30 select * [... join ...] limit 30,60 select * [... join ...] limit 60,90 i guess internally it's performing join operation, consequently obtaining rows later retrieve limited number of rows. problem in example repeating same join operation 3 times , wondering if there way force database store in cache join result join operation performed once , result limited afterwards, or, on other hand, know if there no way can avoid perfor...

i looking fit parabola following data. x = [-10:2:16]; y = [0.0334,0.0230,0.0145,0.0079,0.0033,0.0009,0.0006,0.0026,0.0067,0.0130,0.0213,0.0317,0.0440,0.0580]; [p,~,~] = polyfit(x,y,2); x2 = linspace(-10,16,100); y2 = polyval(p,x2); y3 = 0.0003.*x2.^2 -0.0006.*x2 + 0.0011; figure plot(x,y,'o',x2,y2,x2,y3) however, fit not match data @ all. after putting data excel , fitting using 2nd order polynomial there, nice fit. y = 0.0003x2 - 0.0006x + 0.0011 (excel truncating coefficients skews fit bit). happening polyfit data? solved. matlab checks how many outputs user requesting. since requested 3 outputs though wasn't using them, polyfit changes coefficients map different domain xhat. if instead did: p = polyfit(x,y,2); plot(x2,polyval(p,x2)); then achieve appropriate result. recover same answer using 3 outputs: [p2,s,mu] = polyfit(x,y,2); xhat = (x2-mu(1))./mu(2) y4 = polyval(p2,xhat) plot(x2,y4)

i'm experimenting vue.js , composing components dynamically. there's strange issue although seems updating data correctly, if remove 1 of boxes call splice() removes last item in rendered html. here's example fiddle. i'm testing in chrome. https://jsfiddle.net/afz6jjn0/ just posterity, here's vue component code: vue.component('content-longtext', { template: '#content-longtext', props: { model: { type: string, required: true }, update: { type: function, required: true } }, data() { return { inputdata: this.model } }, methods: { updatecontent(event) { this.update(event.target.value) } }, }) vue.component('content-image', { template: '#content-image', }) vue.component('content-list', { template: '#content-list-template', props: { remove: { type: function, required: true }, update: { type: function, required: true }, views: { type: array, ...

my current file servletconfig, can't show on top of tabs when there many tabs. by default, ide adds new tabs right of active tabs. if space exceeds screen width, new tabs collapses behind "show all"-button. behavior you're expecting. new tabs collapses behind "show all". you have 2 options, disable collapse-mechanism (eventually resulting in tiny tab headers not useful well) or close least used tabs automatically. there no "always show last opened tab". check editor-tab documentation check if setting fits need.

i have set of points pts form loop , looks this: this similar 31243002 , instead of putting points in between pairs of points, fit smooth curve through points (coordinates given @ end of question), tried similar scipy documentation on interpolation : values = pts tck = interpolate.splrep(values[:,0], values[:,1], s=1) xnew = np.arange(2,7,0.01) ynew = interpolate.splev(xnew, tck, der=0) but error: valueerror: error on input data is there way find such fit? coordinates of points: pts = array([[ 6.55525 , 3.05472 ], [ 6.17284 , 2.802609], [ 5.53946 , 2.649209], [ 4.93053 , 2.444444], [ 4.32544 , 2.318749], [ 3.90982 , 2.2875 ], [ 3.51294 , 2.221875], [ 3.09107 , 2.29375 ], [ 2.64013 , 2.4375 ], [ 2.275444, 2.653124], [ 2.137945, 3.26562 ], [ 2.15982 , 3.84375 ], [ 2.20982 , 4.31562 ], [ 2.334704, 4.87873 ], [ 2.314264, 5.5047 ], [ 2.311709, 5.9135 ], [ 2.29638 , 6.42961 ], [ 2.619374, 6...
