What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

# This is sp, the command-line Spotify controller. It talks to a running
# instance of the Spotify Linux client over dbus, providing an interface not
# unlike mpc.
#
# Put differently, it allows you to control Spotify without leaving the comfort
# of your command line, and without a custom client or Premium subscription.

tl;dr

1. Don't run as root.
2. For sessions, set httpOnly (and secure to true if running over SSL) when setting cookies.
3. Use the Helmet for secure headers: https://github.com/evilpacket/helmet
4. Enable csrf for preventing Cross-Site Request Forgery: http://expressjs.com/api.html#csrf
5. Don't use the deprecated bodyParser() and only use multipart explicitly. To avoid multiparts vulnerability to 'temp file' bloat, use the defer property and pipe() the multipart upload stream to the intended destination.

Prerequisites : the letsencrypt CLI tool

This method allows your to generate and renew your Lets Encrypt certificates with 1 command. This is easily automatable to renew each 60 days, as advised.

You need nginx to answer on port 80 on all the domains you want a certificate for. Then you need to serve the challenge used by letsencrypt on /.well-known/acme-challenge. Then we invoke the letsencrypt command, telling the tool to write the challenge files in the directory we used as a root in the nginx configuration.

I redirect all HTTP requests on HTTPS, so my nginx config looks like :

server {

#!/bin/sh

IN=LVDS-0;
setoff() {

    for display in `xrandr | awk '/ disconnected/ {print $1}'`; do
        echo "maybe disabling $display";
        xrandr --output $display --off;
    done;
}

  1. Copy ssh public key to rsync.net server:

  [jim@mb hbdev]$ scp ~/.ssh/id_rsa.pub XXXX@usw-s002.rsync.net:.ssh/authorized_keys
  Password:
  id_rsa.pub
			 100%  392     0.4KB/s   00:00    


  2. Create a local HashBackup backup directory:

package main

import (

	"os"
)
