4sskick / 'let' + 'const' equivalent in ES5
Created September 4, 2016 20:36
'let' + 'const' equivalent in ES5
As we knew that 'let & const' are not coming in ES5, those are coming in ES6 since 2015.
So to make these work like in latest version ECMA Scripts 2015, we can define it by ourself.
'const' - ES6
const a = 1;
'const' - ES5
var a = (function(){
var a = 1;
return function(){
based on tutorial in
and this tutorial to upload existing project into github.
so, you need to create new repository first
- make sure you have installed git in your computer
- open the directory project then open CMD in it
- type 'git init'. This will say "Initialized empty git repository in ....git" (... is the path).
- type 'git add .' Dont forget 'pull stop' mark in the end of add after 'space'. I assume you wanna upload a whole file inside the directory.
- type 'git commit -m "massage here for commit"
This gonna be usefull when U have some pattern actvities to done continously wo/ doing it manually
1. Problem: need to execute `arp -d` continously, the command to delete host on arp table to reset it to first time connect to wifi or other connection gateway. This could even be prevent the user in same connection's gateway which use `internet cut` software (might be myth). Every time the command execute, your computer delete the inet_addr that already chaced to your computer then re-request to gateway point to give you new chace. This usually used when your computer have problem to connect to internet, so your computer need to refresh the chace inet_addr. (I might be wrong sorry, I'm not expert)
echo 'Running command'
set -x #echo on everything the command executed

4sskick / pick random element list java
Last active August 15, 2019 07:21
this methods useful whenever you build dummy data using model
private static <E> List<E> pickNRandomElements(List<E> list, int n, Random r) {
int length = list.size();
if (length < n) return null;
//don't need to shuffle the whole list
for (int i = length - 1; i >= length - n; --i) {
Collections.swap(list, i, r.nextInt(i + 1));
return list.subList(length - n, length);
mongo --eval "db.stats()" # do a simple harmless command of some sort
RESULT=$? # returns 0 if mongo eval succeeds
if [ $RESULT -ne 0 ]; then
echo "MongoDB service is not running, try to run with admin"
sleep 3 #3 secs
exit 1
echo 'Trying to STOP service MongoDB'
set -x #for echo on
net stop MongoDB
echo 'Done STOP service MongoDB'
sleep 3 #3 secs
