Javascript Virtual DOM Framework Benchmark

Recently I found a framework benchmark for javascript (round4 2016-09-12), it shows a lot information. The fastest ranker are:

Framework	Version	Runtime Ratio (% slower than fastest)	MB Start	MB 1K rows
vanillajs		1	2.98	4.85
inferno	1.0.0-beta9	3	3.19	6.60
vanillajs-keyed		4	2.98	4.81
dio.js	3.0.5	4	3.19	7.09
domvm	2.0.0-beta	10	3.15	7.43
kivi	1.0.0-rc2	17	3.17	6.69

Also there are another benchmark (this have fewer framework, last result at this time):

Framework	Init Time	First Render Time	Overall Time
kivi[adv] 1.0.0	2,185	25,795	527,703
Inferno 0.7.22	3,340	31,780	553,513
Imba 0.14.3	15,920	26,250	569,895
Bobril 4.38.0	3,430	26,255	682,847
Vidom 0.3.16	3,400	38,220	729,882
Maquette 2.3.3	1,955	27,410	733,165
Snabbdom 0.5.0	2,565	34,710	759,481
React 15.3.1	38,640	56,065	926,403
React-lite 0.15.6	6,345	40,725	1,105,627
Preact 5.4.0	2,550	53,585	1,150,506
Vanilla[innerHTML] 1.0.0	1,790	16,925	1,500,676
Deku 2.0.0-rc16	3,285	45,950	1,598,787
Mercury 14.1.0	2,840	41,325	2,115,253
yo-yo 1.2.2	1,825	21,835	2,295,505

Apparently there are a lot of them around the internet.

Of course you can build your own framework, here's the tips if you plan doing so.

Rescue the Princess using 8 Programming Languages

For the lolz, source.

LXC Web Panel

As you (probably) already know, LXC (Linux Containers) or OpenVZ an operating-system-level virtualization is really faster than hardware virtualization, see the comparison. For those who hate CLI, you can use web interface called LXC Web Panel (for LXC 0.7 to 0.9, or newer fork 1.0+ here) to manage your containers:

wget https://lxc-webpanel.github.io/tools/install.sh -O - | sudo bash

This software only works on Ubuntu 12.04 or later. Despite of its performance, of course there are limitations, such as: you can only use host OS and architecture on guest. You can find more info on their website or this blog post.

So why LXC instead of Docker or Virtualization? because it's simpler :3 yes, both are different kind of animal, don't forget to check LXD and other alternatives too.

Best Video about Bitcoin and Blockchain

This is old (2013), but quite informative, the explanation about BitCoin and BlockChain.

Go would be a drum :3

ZSH is better BASH!

ZSH is better BASH, you should really change to newer and better shell.
Why it's better? it has better completion, support right prompt, see this presentation for more

Here's how to install it on ArchLinux:

pacman -S zsh zsh-completions
chsh -s `which zsh`
sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

Oh-My-Zsh is package manager for zsh, you can change theme, add more aliases, for example:

plugins=(git git-extras redis-cli sudo systemd archlinux)

You can also install another theme, such as bullet-train:

mkdir $ZSH_CUSTOM/themes
cd $ZSH_CUSTOM/themes
aria2c "http://raw.github.com/caiogondim/bullet-train-oh-my-zsh-theme/master/bullet-train.zsh-theme"

Then set on ~/.zshrc:

BULLETTRAIN_DIR_EXTENDED=2
ZSH_THEME="bullet-train"

Remap Capslock to Backspace on Linux

Greatest idea IMHO from Colemak keyboard layout is replacing capslock with backspace key.

Here's how to do it in linux:

setxkbmap -option caps:backspace

But if you really need capslock, you can set pressing both shift key:

setxkbmap -option shift:both_capslock

These can be set on the ~/.xprofile file. For more xkeyboard tips, see this blog post.

On Mac OSX you can use Karabiner, for Windows, you look at this blog post.

Btw, have you heard about cheapest mechanical keyboard Nimxo K005?
