amazon web services - Create copy of EC2 instance and launch as new instances -


i setup 1 mail server in 1 ec2 instances. want copy whole instance , launch new instance.

i'm confused snapshot , ami, please suggest how it.

when talking creating copy or clone of instance, there's 2 aspects consider:

  • the configuration of instance itself, such instance type, security group, iam role , network subnet
  • the contents of disk volume(s)

to launch instance same instance configuration, use launch more this option in actions menu, can launch new instance same configuration. select original ami used launch initial instance -- please note means have same disk sued when launching initial instance, not have copy of data stored/changed on initial instance since first started.

if wish make perfect copy of instance, including contents of disk volume(s), create ami (see documentation linux , windows). make copy of disk volume(s) instance launched ami have same data on disk. then, launch new instance ami.

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
