Add real emojis and icons to mintty bash on windows

Posted on 24.11.202110.11.2021 by mario

Installing git for windows isn’t hard anymore. I recommend installing “Git for Windows SDK” so you can install extra packages via Pacman. I like fish shell and tmux, and those aren’t included in the default installer. Either way, you can run bash and or fish on windows. The emojis and icons however don’t look very pretty, more like DOS-style.

Open a shell and cd to

C:\Program Files\Git\usr\share\mintty\emojis or C:\git-sdk-64\usr\share\mintty\emojis depending what installation you chose.

cd C:\git-sdk-64\usr\share\mintty\
mkdir emojis
cd emojis
curl -LO https://raw.githubusercontent.com/wiki/mintty/mintty/getemojis
getemoji -d
getemoji .

In mintty:
Options -> Text -> Emojis -> style: google
Options -> Text -> Character set -> UTF-8

On Windows Server is can be a hassle to find the start-up folder/autostart folder. Quick shortcut: Win Key + R -> shell:startup

jQuery bind after ajax load

Posted on 01.11.202106.10.2021 by mario

Sometimes it is needed to add a jQuery event listener to an element that isn’t present in the DOM at the creation of the page but created during runtime or the result of an ajax call.

What doesn’t work is

jQuery(document).ready(function () {
    jQuery('.selector').on({
        click: function  (event){
            event.preventDefault();
            console.log('I work only with existing elements');
        }
    });
});

However, there is a way to achieve that.

jQuery(document).ready(function () {
    jQuery(document).on('click', '.selector', function (event){
        event.preventDefault();
        console.log('I work with a dynamically created elements');
    });
});

Windows share timeout

Posted on 10.10.202126.08.2021 by mario

Microsoft hat eine Autodisconnect-Funktion für RAS- und LAN-Verbindungen.

Die Standardzeit auf Servern und PC liegt bei 15 Minuten.

Mit dem Befehl

net config server /autodisconnect:-1

kann die o.g. Funktion abschalten, oder man gibt eine Zeit in Minuten ein.

(z.B. 600 für 10h)

Enable hibernate / suspend to disk on Windows 10

Posted on 22.08.202120.08.2021 by mario

I don’t know why, but the admins tend to disable hibernate via group policies from time to time. It is pretty simple to enable, but you need admin permissions.
This script first forces UAC and then enables hibernation.

@echo off

:: BatchGotAdmin
:-------------------------------------
REM  --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
    echo Requesting administrative privileges...
    goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
    echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
    echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"

    "%temp%\getadmin.vbs"
    exit /B

:gotAdmin
    if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )
    pushd "%CD%"
    CD /D "%~dp0"
:--------------------------------------

powercfg.exe /hibernate on
