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。

工程師應該放心大膽地創造技術負債

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) 

How To install Docker in Linux Mint 18.2

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
 Git commit:   cec0b72
 Built:        Tue Sep  5 20:00:17 2017
 OS/Arch:      linux/amd64

Server:
 Version:      17.06.2-ce
 API version:  1.30 (minimum version 1.12)
 Go version:   go1.8.3
 Git commit:   cec0b72
 Built:        Tue Sep  5 19:59:11 2017
 OS/Arch:      linux/amd64
 Experimental: false

 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

Linux Mint 17.3 修改預設的字型顏色

sudo gedit  /usr/share/themes/Mint-X/gtk-3.0/gtk-main.css

Linux Mint 18.1 安裝後的幾個設定

TrackPoint 的設定

參考 http://webnexus.de/?p=10
設定如下

Trackpoint sensitivity

Although the trackpoint aswell as trackpoint scrolling worked out of the box the sensitivity was sort of sluggish. To permanently improve the sensitivity I added a new rule as described here: https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X220

In /etc/udev/rules.d/98-trackpoint.rules I added the following lines:

# Set the trackpoint speed and sensitivity
ACTION=="add",SUBSYSTEM=="input",ATTR{name}=="TPPS/2 IBM TrackPoint",ATTR{device/sensitivity}="255",ATTR{device/speed}="110"

To switch sensitivity on the go (settings will be lost on reboot) you can also use configure-trackpoint from the thinkpad-extras repo:

sudo add-apt-repository ppa:linrunner/thinkpad-extras
sudo apt-get update
sudo apt-get install configure-trackpoint

Fcitx 中文輸入法的設定

參考 http://cloverhsc.blogspot.tw/2016/12/linux-mint-18-fcitx.html
設定如下


開機之後fcitx 不會自動啟用。後來去看了 mint控制台的『系統啟動應用程式』發現 Fcitx Qt IMPanel 內容它是去執行
/usr/share/fcitx-qimpanel/fcitx-qimpanel-autostart
這應該是要執行
/usr/bin/fcitx
才對，修改為正確的值，重新啟動後就正常使用了。

中文字型變成標楷或細明的問題

參考 https://magiclen.org/linux-font-remove-kai/
設定如下

sudo apt-get remove fonts-arphic-ukai fonts-arphic-uming直接移除這二套字型就可以了。
