firefox

from: https://stackoverflow.com/questions/945691/automatically-print-image-from-website

The only solution to avoid print dialog that I found was creating a variable on Mozilla Firefox to set auto-print. Maybe is not the best solution if you need to use other browser, but in my case, I only need to print a report automatically and it works:
1- Open Firefox and type "about:config" in the address bar
2- Right click on any preference and select "New" > "Boolean"
3- Add a variable called "print.always_print_silent" with "true" value
4- Restart Firefox.

Google Chrome

--kiosk 的動作，我目前試不出來，猜想應該是新版本不支援了。

在 Linux Mint 18.2 使用 swift 4.02 出現的問題

from: https://bugs.swift.org/browse/SR-3794

在 Linux Mint 18.2 使用 swift 4.02 執行 import Glibc 時，會顯示錯誤訊息， 表示它找不到 函數要 include 的來源位置， 可以用類似以下方式指定要 include 的函數位置，就可以解決了。

swift -I ~/apps/swift-4.0.2-RELEASE-ubuntu16.04/usr/lib/swift/clang/include/

後面的路徑，是 swift 解壓縮（或安裝）的資料夾位置。

若要停止、移除、刪掉 Docker images 檔案，可以用以下方式處理：

docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)

docker rmi $(docker ps -a -q)

Docker for Linux Mint is availabe as a free Community Edition (CE). Installation is easy and straigh forward. We will install a stable release of docker.
OS Requirements

• Linux Mint 18.2 (LTS)
• Architecture: x86_64

If you've the older version installed already, uninstall it

$ sudo apt-get remove docker docker-engine docker.io

Add repositories

$ sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Since, Linux Mint 18.2 (sonya) is based on Ubuntu 16.04 (xenial), we've to use the release codename of Ubuntu 16.04 i.e. xenial. Also, we'll use the latest stable version

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable"

If you are using Linux Mint 16 (petra), you've to use the release codename "trusty"
To check the release codename of you Linux Mint pc, In your terminal type:

lsb_release -rc

You'll see the release and codename printed in the terminal as

Release: 18.2
Codename: sonya

Now, update the pc

$ sudo apt update

Finally, we'll Install docker community version (CE) in Linux mint 18.2

$ sudo apt install docker-ce

Check if the docker is properly installed by typing

$ docker version

You'll get the output like this:

Client:
 Version:      17.06.2-ce
 API version:  1.30
 Go version:   go1.8.3

Server:
 Version:      17.06.2-ce

 Running hello world in docker is easy, Just run

$ sudo docker run hello-world

You must be root user to use docker

Running docker command as non root user

If you are a single user and don't want to enter your password everytime while executing docker command, you have to add the current user in docker group.

$ sudo groupadd docker #this is most likely already created while installing docker
$ sudo gpasswd -a $USER docker
$ newgrp docker # you might need to logout if the changes are not working
$ docker run hello-world # check if docker is working without sudo
