css - Center image in DIV and hide the overflowing -


this kind of unique case. trying achieve following:

  1. square images should 100% 100%. fill out entire div (which squared)
  2. all images should fill out entire height of div.
  3. all images should aligned center
  4. if overflow x-axis, should overflow , hide

https://jsfiddle.net/cxnylxfn/2/

.image-container {     position: relative;     width: 300px;     height: 300px;     display: inline-block;     margin: 20px;     border: 1px solid black;     float: left;     overflow: hidden; }  .image-container img {     height: 100%;     position: absolute;     left: 0;     right: 0;     margin: 0 auto; }

i achieved this, except centering images no matter what. google logo should centered , rest fine are. how achieve 4 requirements?

i use flex approach this: 

.image-container {    display: flex;    width: 300px;    height: 300px;    border: 1px solid black;    overflow: hidden;    position: relative;    align-items: center;    justify-content: center;  }    img {    display: block;    height: 100%;  }
<div class="image-container">    <img src="https://assets-cdn.github.com/images/modules/logos_page/github-mark.png" />  </div>  <div class="image-container">    <img src="https://i.kinja-img.com/gawker-media/image/upload/s--peksmwzm--/c_scale,fl_progressive,q_80,w_800/1414228815325188681.jpg" />  </div>  <div class="image-container">    <img src="http://www.zevendesign.com/wp-content/uploads/2015/04/google-logo-progress-270x480.jpg" />  </div>  <div class="image-container">    <img src="https://cdn.pixabay.com/photo/2015/10/31/12/56/google-1015752_960_720.png" />  </div>

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
