Run a Python script on Heroku on schedule (as a separate app) -


ok i'm working on app has 2 heroku apps - 1 writer writes db after scraping site, , 1 reader consumes said db.

the former python script has kind of while 1 loop - it's twitter stream. want run every x minutes independent of reader doing.

now, running script locally works fine, i'm not sure how getting work on heroku work. i've tried looking up, not find solid answer. read background tasks, redis queue, one-off dynos etc, i'm not sure use purpose. of requirements are:

  1. have python script keep logs of whatever want.
  2. in future, might want add admin panel writer, show me stats of script (and logs). hooking admin panel (flask) should easy-ish , not break script itself.

i love suggestions or pointers here.

  1. i suggest writing consumer server waits around, processes stream on timed interval. is, start once , runs forever, doing processing every 10 minutes or so.

    see: sched python module, handles scheduling events @ times , running them.

  2. simpler: use heroku's scheduler service.

this technique simpler -- it's straight-through code -- can lead problems if have 2 of same consumer running @ same time.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
