automatically create a folder with today's date

run python script as ubuntu service

step 1 - create service file here is archivebot.service I created for my server

   

[Unit]
Description=archivebot

[Service]
ExecStart=/bin/bash -c "cd /home/al/slack-archive-bot;export SLACK_API_TOKEN=TOKEN_HERE && python archivebot.py"

[Install]
WantedBy=multi-user.target

Then I did everything according to this example :

Step 1: I created this file (note location) which essentially fires a bash process with an extended argument. You could fire your own command which could be different from bash.

   

[root@y500-fedora ~]# cat /etc/systemd/system/foo.service 
[Unit]
Description=foo

[Service]
ExecStart=/bin/bash -c "while true; do /bin/inotifywait -qq --event close_write /sys/class/backlight/acpi_video0/brightness; su myusername -c '/bin/xbacklight -display :0 -set $(cat /sys/class/backlight/acpi_video0/brightness)'; done"

[Install]
WantedBy=multi-user.target

Step 2:

Reload systemd:

systemctl daemon-reload

Start the new service:

systemctl enable foo

(similarly you can disable it)

(optional) Step 3: It should start automatically at next reboot into multi-user mode (run level 3) but if you want to start it right away:

systemctl start foo
systemctl status foo # optional, just to verify

Update: For completeness, I should add that ubuntu bionic seems to have a very thorough man page. RTFM here

Study path for artificial intelligence and Machine learning:

Andrew Ng's lecture series on AI

Andrew Ng's lecture at the Stanford Business School

Andrew Ng - The State of Artificial Intelligence

Andrew Ng is a visiting professor at Stanford, founder of Coursera and currently the head of research at Alibaba. The above videos should give you all the basics you need about AI.

Below schema from this article I like this map below - because there are a lot of areas and directions in learning AI it shows it as subway map: AI study map

powershell sitecore remove item from pipe separated list

here is fucntion how to do it :

   
[string]$test ="{uka}|{taka}|{4aka}|{boom}"


function RemovePipeElement {
    param (
        [string]$body,
        [string]$elem

    )
    [string]$res=$body;
    [int]$a=$body.IndexOf($elem)
    if ($a -gt -1) {
        [string]$newbod="";
        [bool] $first=$TRUE;
        $arr=$body.split("|");

        foreach ($e in $arr) {
            if ($e -ne $elem ) {
                if ($first){
                    [string]$newbod=$e;
                    $first=$FALSE;
                }else{
                    [string]$newbod=$newbod+"|"+$e;
                }
            }
        }
        $res=$newbod;
    }

        return $res;
}

 Write-Host "$test"

 [string]$uid=RemovePipeElement $test "{uka}";

 [string]$uid=RemovePipeElement $test "{4aka}";
