javascript - gulp tasks could be combined to be faster? -


i have gulp file wrote , i'm new @ this. it's working have more tasks think need.

can me string javascript tasks 1 task?

i need 4 separate js files uglified when i'm done.

relevant code snippet gulpfile.js:

    var gulp = require('gulp')         uglify = require('gulp-uglify'),         rename = require('gulp-rename'),         concat = require('gulp-concat'),         notify = require('gulp-notify'),         cache = require('gulp-cache'),         del = require('del');       gulp.task('clean', function(cb) {         del(['css/*', 'js/min/*'], cb)     });      gulp.task('featuretest', function() {         return gulp.src('js/feature-test.js')         .pipe(rename({suffix: '.min'}))         .pipe(uglify())         .pipe(gulp.dest('js/min'))     });      // file: '/js/excanvas.min.js' loaded via lte ie8 conditional statement     gulp.task('excanvas', function() {         return gulp.src('js/polyfills/excanvas.js')         .pipe(rename({suffix: '.min'}))         .pipe(uglify())         .pipe(gulp.dest('js/min'))     });      // file: '/js/charts.min.js' used on few pages     gulp.task('charts', function() {         return gulp.src(['js/highcharts-4.0.1.js', 'js/usfa-theme.js'])         .pipe(concat('charts.js'))         .pipe(rename({suffix: '.min'}))         .pipe(uglify())         .pipe(gulp.dest('js/min'))     });      // file: '/js/main.min.js' concat of 'libs/jquery', few polyfills (except excanvas.js , highcharts)     gulp.task('scripts', function() {         return gulp.src(['js/libs/*.js', 'js/plugins/*.js', 'js/polyfills/*.js', '!js/excanvas.js', '!js/highcharts-4.0.1.js', 'js/custom.js'])         .pipe(concat('main.js'))         .pipe(rename({suffix: '.min'}))         .pipe(uglify())         .pipe(gulp.dest('js/min'))          .pipe(notify({ message: 'scripts task complete' }));     });      gulp.task('watch', function() {        // watch .js files       gulp.watch('js/**/*.js', ['featuretest', 'excanvas', 'charts', 'scripts']);      });        gulp.task('default', ['clean'], function() {         gulp.start('featuretest', 'excanvas', 'charts', 'scripts');     });

what trying do:

    var gulp = require('gulp')         uglify = require('gulp-uglify'),         rename = require('gulp-rename'),         concat = require('gulp-concat'),         notify = require('gulp-notify'),         cache = require('gulp-cache'),         del = require('del');       gulp.task('clean', function(cb) {         del(['css/*', 'js/min/*'], cb)     });      gulp.task('scripts', function() {     // file: '/js/feature-test.js' loaded in doc <head>         return gulp.src('js/feature-test.js')         .pipe(rename({suffix: '.min'}))         .pipe(uglify())         .pipe(gulp.dest('js/min'))      // file: '/js/excanvas.min.js' loaded via lte ie8 conditional statement @ end of doc             return gulp.src('js/polyfills/excanvas.js')         .pipe(rename({suffix: '.min'}))         .pipe(uglify())         .pipe(gulp.dest('js/min'))      // file: '/js/charts.min.js' used on few pages , loaded when needed @ end of doc         return gulp.src(['js/highcharts-4.0.1.js', 'js/usfa-theme.js'])         .pipe(concat('charts.js'))         .pipe(rename({suffix: '.min'}))         .pipe(uglify())         .pipe(gulp.dest('js/min'))      // file: '/js/main.min.js' concat of 'libs/jquery', few polyfills (except excanvas.js , high charts), loaded @ end of every doc          return gulp.src(['js/libs/*.js', 'js/plugins/*.js', 'js/polyfills/*.js', '!js/excanvas.js', '!js/highcharts-4.0.1.js', 'js/custom.js'])         .pipe(concat('main.js'))         .pipe(rename({suffix: '.min'}))         .pipe(uglify())         .pipe(gulp.dest('js/min'))          .pipe(notify({ message: 'scripts task complete' }));     });      gulp.task('watch', function() {        // watch .js files       gulp.watch('js/**/*.js', ['scripts']);      });        gulp.task('default', ['clean'], function() {         gulp.start('scripts');     });

if you're asking question how combine separate operations single task, can combine streams gulp-util.

var gulp = require('gulp')     uglify = require('gulp-uglify'),     util = require('gulp-util');  gulp.task('scripts', function() {     var featuretest = gulp.src('js/feature-test.js')...      var excanvas = gulp.src('js/polyfills/excanvas.js')...      var charts = gulp.src(['js/highcharts-4.0.1.js', 'js/usfa-theme.js'])...      var scripts = gulp.src(['js/libs/*.js', 'js/plugins/*.js', 'js/polyfills/*.js', '!js/excanvas.js', '!js/highcharts-4.0.1.js', 'js/custom.js'])...     // combine streams    return util.combine(featuretest, excanvas, charts, scripts); });

this give single task, it's not faster. if you're not forcing things sequential, gulp fast it's gonna be.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
