Linux Desktop Setup
======
My software setup has been surprisingly constant over the last decade, after a few years of experimentation since I initially switched to Linux in 2006. It might be interesting to look back in another 10 years and see what changed. A quick overview of what’s running as I’m writing this post:
[![htop overview][1]][2]
### Motivation
My software priorities are, in no specific order:
* Programs should run on my local system so that I’m in control of them, this excludes cloud solutions.
* Programs should run in the terminal, so that they can be used consistently from anywhere, including weak computers or a phone.
* Keyboard focused is nearly automatic by using terminal software. I prefer to use the mouse where it makes sense only, reaching for the mouse all the time during typing feels like a waste of time. Occasionally it took me an hour to notice that the mouse wasn’t even plugged in.
* Ideally use fast and efficient software, I don’t like hearing the fan and feeling the room heat up. I can also keep running older hardware for much longer, my 10 year old Thinkpad x200s is still fine for all the software I use.
* Be composable. I don’t want to do every step manually, instead automate more when it makes sense. This naturally favors the shell.
### Operating Systems
I had a hard start with Linux 12 years ago by removing Windows, armed with just the [Gentoo Linux][3] installation CD and a printed manual to get a functioning Linux system. It took me a few days of compiling and tinkering, but in the end I felt like I had learnt a lot.
I haven’t looked back to Windows since then, but I switched to [Arch Linux][4] on my laptop after having the fan fail from the constant compilation stress. Later I also switched all my other computers and private servers to Arch Linux. As a rolling release distribution you get package upgrades all the time, but the most important breakages are nicely reported in the [Arch Linux News][5].
One annoyance though is that Arch Linux removes the old kernel modules once you upgrade it. I usually notice that once I try plugging in a USB flash drive and the kernel fails to load the relevant module. Instead you’re supposed to reboot after each kernel upgrade. There are a few [hacks][6] around to get around the problem, but I haven’t been bothered enough to actually use them.
Similar problems happen with other programs, commonly Firefox, cron or Samba requiring a restart after an upgrade, but annoyingly not warning you that that’s the case. [SUSE][7], which I use at work, nicely warns about such cases.
For the [DDNet][8] production servers I prefer [Debian][9] over Arch Linux, so that I have a lower chance of breakage on each upgrade. For my firewall and router I used [OpenBSD][10] for its clean system, documentation and great [pf firewall][11], but right now I don’t have a need for a separate router anymore.
### Window Manager
Since I started out with Gentoo I quickly noticed the huge compile time of KDE, which made it a no-go for me. I looked around for more minimal solutions, and used [Openbox][12] and [Fluxbox][13] initially. At some point I jumped on the tiling window manager train in order to be more keyboard-focused and picked up [dwm][14] and [awesome][15] close to their initial releases.
In the end I settled on [xmonad][16] thanks to its flexibility, extendability and being written and configured in pure [Haskell][17], a great functional programming language. One example of this is that at home I run a single 40” 4K screen, but often split it up into four virtual screens, each displaying a workspace on which my windows are automatically arranged. Of course xmonad has a [module][18] for that.
[dzen][19] and [conky][20] function as a simple enough status bar for me. My entire conky config looks like this:
```
out_to_console yes
update_interval 1
total_run_times 0
TEXT
${downspeed eth0} ${upspeed eth0} | $cpu% ${loadavg 1} ${loadavg 2} ${loadavg 3} $mem/$memmax | ${time %F %T}
```
And gets piped straight into dzen2 with `conky | dzen2 -fn '-xos4-terminus-medium-r-normal-*-12-*-*-*-*-*-*-*' -bg '#000000' -fg '#ffffff' -p -e '' -x 1000 -w 920 -xs 1 -ta r`.
One important feature for me is to make the terminal emit a beep sound once a job is done. This is done simply by adding a `\a` character to the `PR_TITLEBAR` variable in zsh, which is shown whenever a job is done. Of course I disable the actual beep sound by blacklisting the `pcspkr` kernel module with `echo "blacklist pcspkr" > /etc/modprobe.d/nobeep.conf`. Instead the sound gets turned into an urgency by urxvt’s `URxvt.urgentOnBell: true` setting. Then xmonad has an urgency hook to capture this and I can automatically focus the currently urgent window with a key combination. In dzen I get the urgent windowspaces displayed with a nice and bright `#ff0000`.
The final result in all its glory on my Laptop:
[![Laptop screenshot][21]][22]
I hear that [i3][23] has become quite popular in the last years, but it requires more manual window alignment instead of specifying automated methods to do it.
I realize that there are also terminal multiplexers like [tmux][24], but I still require a few graphical applications, so in the end I never used them productively.
### Terminal Persistency
In order to keep terminals alive I use [dtach][25], which is just the detach feature of screen. In order to make every terminal on my computer detachable I wrote a [small wrapper script][26]. This means that even if I had to restart my X server I could keep all my terminals running just fine, both local and remote.
### Shell & Programming
Instead of [bash][27] I use [zsh][28] as my shell for its huge number of features.
As a terminal emulator I found [urxvt][29] to be simple enough, support Unicode and 256 colors and has great performance. Another great feature is being able to run the urxvt client and daemon separately, so that even a large number of terminals barely takes up any memory (except for the scrollback buffer).
There is only one font that looks absolutely clean and perfect to me: [Terminus][30]. Since i’s a bitmap font everything is pixel perfect and renders extremely fast and at low CPU usage. In order to switch fonts on-demand in each terminal with `CTRL-WIN-[1-7]` my ~/.Xdefaults contains:
```
URxvt.font: -xos4-terminus-medium-r-normal-*-14-*-*-*-*-*-*-*
dzen2.font: -xos4-terminus-medium-r-normal-*-14-*-*-*-*-*-*-*
URxvt.keysym.C-M-1: command:\033]50;-xos4-terminus-medium-r-normal-*-12-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-2: command:\033]50;-xos4-terminus-medium-r-normal-*-14-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-3: command:\033]50;-xos4-terminus-medium-r-normal-*-18-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-4: command:\033]50;-xos4-terminus-medium-r-normal-*-22-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-5: command:\033]50;-xos4-terminus-medium-r-normal-*-24-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-6: command:\033]50;-xos4-terminus-medium-r-normal-*-28-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-7: command:\033]50;-xos4-terminus-medium-r-normal-*-32-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-n: command:\033]10;#ffffff\007\033]11;#000000\007\033]12;#ffffff\007\033]706;#00ffff\007\033]707;#ffff00\007
URxvt.keysym.C-M-b: command:\033]10;#000000\007\033]11;#ffffff\007\033]12;#000000\007\033]706;#0000ff\007\033]707;#ff0000\007
```
For programming and writing I use [Vim][31] with syntax highlighting and [ctags][32] for indexing, as well as a few terminal windows with grep, sed and the other usual suspects for search and manipulation. This is probably not at the same level of comfort as an IDE, but allows me more automation.
One problem with Vim is that you get so used to its key mappings that you’ll want to use them everywhere.
[Python][33] and [Nim][34] do well as scripting languages where the shell is not powerful enough.
### System Monitoring
[htop][35] (look at the background of that site, it’s a live view of the server that’s hosting it) works great for getting a quick overview of what the software is currently doing. [lm_sensors][36] allows monitoring the hardware temperatures, fans and voltages. [powertop][37] is a great little tool by Intel to find power savings. [ncdu][38] lets you analyze disk usage interactively.
[nmap][39], iptraf-ng, [tcpdump][40] and [Wireshark][41] are essential tools for analyzing network problems.
There are of course many more great tools.
### Mails & Synchronization
On my home server I have a [fetchmail][42] daemon running for each email acccount that I have. Fetchmail just retrieves the incoming emails and invokes [procmail][43]:
```
#!/bin/sh
for i in /home/deen/.fetchmail/*; do
FETCHMAILHOME=$i /usr/bin/fetchmail -m 'procmail -d %T' -d 60
done
```
The configuration is as simple as it could be and waits for the server to inform us of fresh emails:
```
poll imap.1und1.de protocol imap timeout 120 user "dennis@felsin9.de" password "XXX" folders INBOX keep ssl idle
```
My `.procmailrc` config contains a few rules to backup all mails and sort them into the correct directories, for example based on the mailing list id or from field in the mail header:
```
MAILDIR=/home/deen/shared/Maildir
LOGFILE=$HOME/.procmaillog
LOGABSTRACT=no
VERBOSE=off
FORMAIL=/usr/bin/formail
NL="
"
:0wc
* ! ? test -d /media/mailarchive/`date +%Y`
| mkdir -p /media/mailarchive/`date +%Y`
# Make backups of all mail received in format YYYY/YYYY-MM
:0c
/media/mailarchive/`date +%Y`/`date +%Y-%m`
:0
* ^From: .*(.*@.*.kit.edu|.*@.*.uka.de|.*@.*.uni-karlsruhe.de)
$MAILDIR/.uni/
:0
* ^list-Id:.*lists.kit.edu
$MAILDIR/.uni-ml/
[...]
```
To send emails I use [msmtp][44], which is also great to configure:
```
account default
host smtp.1und1.de
tls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
auth on
from dennis@felsin9.de
user dennis@felsin9.de
password XXX
[...]
```
But so far the emails are still on the server. My documents are all stored in a directory that I synchronize between all computers using [Unison][45]. Think of Unison as a bidirectional interactive [rsync][46]. My emails are part of this documents directory and thus they end up on my desktop computers.
This also means that while the emails reach my server immediately, I only fetch them on deman instead of getting instant notifications when an email comes in.
From there I read the mails with [mutt][47], using the sidebar plugin to display my mail directories. The `/etc/mailcap` file is essential to display non-plaintext mails containing HTML, Word or PDF:
```
text/html;w3m -I %{charset} -T text/html; copiousoutput
application/msword; antiword %s; copiousoutput
application/pdf; pdftotext -layout /dev/stdin -; copiousoutput
```
### News & Communication
[Newsboat][48] is a nice little RSS/Atom feed reader in the terminal. I have it running on the server in a `tach` session with about 150 feeds. Filtering feeds locally is also possible, for example:
```
ignore-article "https://forum.ddnet.tw/feed.php" "title =~ \"Map Testing •\" or title =~ \"Old maps •\" or title =~ \"Map Bugs •\" or title =~ \"Archive •\" or title =~ \"Waiting for mapper •\" or title =~ \"Other mods •\" or title =~ \"Fixes •\""
```
I use [Irssi][49] the same way for communication via IRC.
### Calendar
[remind][50] is a calendar that can be used from the command line. Setting new reminders is done by editing the `rem` files:
```
# One time events
REM 2019-01-20 +90 Flight to China %b
# Recurring Holidays
REM 1 May +90 Holiday "Tag der Arbeit" %b
REM [trigger(easterdate(year(today()))-2)] +90 Holiday "Karfreitag" %b
# Time Change
REM Nov Sunday 1 --7 +90 Time Change (03:00 -> 02:00) %b
REM Apr Sunday 1 --7 +90 Time Change (02:00 -> 03:00) %b
# Birthdays
FSET birthday(x) "'s " + ord(year(trigdate())-x) + " birthday is %b"
REM 16 Apr +90 MSG Andreas[birthday(1994)]
# Sun
SET $LatDeg 49
SET $LatMin 19
SET $LatSec 49
SET $LongDeg -8
SET $LongMin -40
SET $LongSec -24
MSG Sun from [sunrise(trigdate())] to [sunset(trigdate())]
[...]
```
Unfortunately there is no Chinese Lunar calendar function in remind yet, so Chinese holidays can’t be calculated easily.
I use two aliases for remind:
```
rem -m -b1 -q -g
```
to see a list of the next events in chronological order and
```
rem -m -b1 -q -cuc12 -w$(($(tput cols)+1)) | sed -e "s/\f//g" | less
```
to show a calendar fitting just the width of my terminal:
![remcal][51]
### Dictionary
[rdictcc][52] is a little known dictionary tool that uses the excellent dictionary files from [dict.cc][53] and turns them into a local database:
```
$ rdictcc rasch
====================[ A => B ]====================
rasch:
- apace
- brisk [speedy]
- cursory
- in a timely manner
- quick
- quickly
- rapid
- rapidly
- sharpish [Br.] [coll.]
- speedily
- speedy
- swift
- swiftly
rasch [gehen]:
- smartly [quickly]
Rasch {n} [Zittergras-Segge]:
- Alpine grass [Carex brizoides]
- quaking grass sedge [Carex brizoides]
Rasch {m} [regional] [Putzrasch]:
- scouring pad
====================[ B => A ]====================
Rasch model:
- Rasch-Modell {n}
```
### Writing and Reading
I have a simple todo file containing my tasks, that is basically always sitting open in a Vim session. For work I also use the todo file as a “done” file so that I can later check what tasks I finished on each day.
For writing documents, letters and presentations I use [LaTeX][54] for its superior typesetting. A simple letter in German format can be set like this for example:
```
\documentclass[paper = a4, fromalign = right]{scrlttr2}
\usepackage{german}
\usepackage{eurosym}
\usepackage[utf8]{inputenc}
\setlength{\parskip}{6pt}
\setlength{\parindent}{0pt}
\setkomavar{fromname}{Dennis Felsing}
\setkomavar{fromaddress}{Meine Str. 1\\69181 Leimen}
\setkomavar{subject}{Titel}
\setkomavar*{enclseparator}{Anlagen}
\makeatletter
\@setplength{refvpos}{89mm}
\makeatother
\begin{document}
\begin{letter} {Herr Soundso\\Deine Str. 2\\69121 Heidelberg}
\opening{Sehr geehrter Herr Soundso,}
Sie haben bei mir seit dem Bla Bla Bla.
Ich fordere Sie hiermit zu Bla Bla Bla auf.
\closing{Mit freundlichen Grüßen}
\end{letter}
\end{document}
```
Further example documents and presentations can be found over at [my private site][55].
To read PDFs [Zathura][56] is fast, has Vim-like controls and even supports two different PDF backends: Poppler and MuPDF. [Evince][57] on the other hand is more full-featured for the cases where I encounter documents that Zathura doesn’t like.
### Graphical Editing
[GIMP][58] and [Inkscape][59] are easy choices for photo editing and interactive vector graphics respectively.
In some cases [Imagemagick][60] is good enough though and can be used straight from the command line and thus automated to edit images. Similarly [Graphviz][61] and [TikZ][62] can be used to draw graphs and other diagrams.
### Web Browsing
As a web browser I’ve always used [Firefox][63] for its extensibility and low resource usage compared to Chrome.
Unfortunately the [Pentadactyl][64] extension development stopped after Firefox switched to Chrome-style extensions entirely, so I don’t have satisfying Vim-like controls in my browser anymore.
### Media Players
[mpv][65] with hardware decoding allows watching videos at 5% CPU load using the `vo=gpu` and `hwdec=vaapi` config settings. `audio-channels=2` in mpv seems to give me clearer downmixing to my stereo speakers / headphones than what PulseAudio does by default. A great little feature is exiting with `Shift-Q` instead of just `Q` to save the playback location. When watching with someone with another native tongue you can use `--secondary-sid=` to show two subtitles at once, the primary at the bottom, the secondary at the top of the screen
My wirelss mouse can easily be made into a remote control with mpv with a small `~/.config/mpv/input.conf`:
```
MOUSE_BTN5 run "mixer" "pcm" "-2"
MOUSE_BTN6 run "mixer" "pcm" "+2"
MOUSE_BTN1 cycle sub-visibility
MOUSE_BTN7 add chapter -1
MOUSE_BTN8 add chapter 1
```
[youtube-dl][66] works great for watching videos hosted online, best quality can be achieved with `-f bestvideo+bestaudio/best --all-subs --embed-subs`.
As a music player [MOC][67] hasn’t been actively developed for a while, but it’s still a simple player that plays every format conceivable, including the strangest Chiptune formats. In the AUR there is a [patch][68] adding PulseAudio support as well. Even with the CPU clocked down to 800 MHz MOC barely uses 1-2% of a single CPU core.
![moc][69]
My music collection sits on my home server so that I can access it from anywhere. It is mounted using [SSHFS][70] and automount in the `/etc/fstab/`:
```
root@server:/media/media /mnt/media fuse.sshfs noauto,x-systemd.automount,idmap=user,IdentityFile=/root/.ssh/id_rsa,allow_other,reconnect 0 0
```
### Cross-Platform Building
Linux is great to build packages for any major operating system except Linux itself! In the beginning I used [QEMU][71] to with an old Debian, Windows and Mac OS X VM to build for these platforms.
Nowadays I switched to using chroot for the old Debian distribution (for maximum Linux compatibility), [MinGW][72] to cross-compile for Windows and [OSXCross][73] to cross-compile for Mac OS X.
The script used to [build DDNet][74] as well as the [instructions for updating library builds][75] are based on this.
### Backups
As usual, we nearly forgot about backups. Even if this is the last chapter, it should not be an afterthought.
I wrote [rrb][76] (reverse rsync backup) 10 years ago to wrap rsync so that I only need to give the backup server root SSH rights to the computers that it is backing up. Surprisingly rrb needed 0 changes in the last 10 years, even though I kept using it the entire time.
The backups are stored straight on the filesystem. Incremental backups are implemented using hard links (`--link-dest`). A simple [config][77] defines how long backups are kept, which defaults to:
```
KEEP_RULES=( \
7 7 \ # One backup a day for the last 7 days
31 8 \ # 8 more backups for the last month
365 11 \ # 11 more backups for the last year
1825 4 \ # 4 more backups for the last 5 years
)
```
Since some of my computers don’t have a static IP / DNS entry and I still want to back them up using rrb I use a reverse SSH tunnel (as a systemd service) for them:
```
[Unit]
Description=Reverse SSH Tunnel
After=network.target
[Service]
ExecStart=/usr/bin/ssh -N -R 27276:localhost:22 -o "ExitOnForwardFailure yes" server
KillMode=process
Restart=always
[Install]
WantedBy=multi-user.target
```
Now the server can reach the client through `ssh -p 27276 localhost` while the tunnel is running to perform the backup, or in `.ssh/config` format:
```
Host cr-remote
HostName localhost
Port 27276
```
While talking about SSH hacks, sometimes a server is not easily reachable thanks to some bad routing. In that case you can route the SSH connection through another server to get better routing, in this case going through the USA to reach my Chinese server which had not been reliably reachable from Germany for a few weeks:
```
Host chn.ddnet.tw
ProxyCommand ssh -q usa.ddnet.tw nc -q0 chn.ddnet.tw 22
Port 22
```
### Final Remarks
Thanks for reading my random collection of tools. I probably forgot many programs that I use so naturally every day that I don’t even think about them anymore. Let’s see how stable my software setup stays in the next years. If you have any questions, feel free to get in touch with me at [dennis@felsin9.de][78].

Linux桌面设置
======
从 2006 年开始转战 Linux 系统后，经过几年的实践，我的软件设置在过去十年内出人意料的固定。再过十年回顾一下，看看发生了什么，也许会非常有趣。在写这篇推文时，我迅速回顾了正在运行的内容：
[![htop overview][1]][2]
### 契机
我的软件介绍排序不分先后：
* 程序应该运行在本地系统中以便我可以控制它，这其中并不包括云解决方案。
* 程序应在终端中运行，以便于在任何地方连贯地使用它们，包括性能稍差的电脑或手机。
* 通过使用终端软件，可以实现自动聚焦键盘。只有在一些有意义的地方，我会更喜欢使用鼠标，因为在打字期间一直伸手去拿鼠标感觉像在浪费时间。有时候过了一个小时我才注意到甚至还没有插鼠标。
* 最好使用快速高效的软件，我不喜欢听到风扇的声音和感到房间在变热。我还可以继续长久地运行旧硬件，已经使用了 10 年的 Thinkpad x200s 还能很好地支持我所使用的软件。
* 组合。我不想手动执行每个步骤，而是在需要时自动执行更多操作，这时自然是支持 shell。
### 操作系统
十二年前移除 Windows 系统后，我在 Linux 系统上经历了一个艰难的开始，当时我手上只有 [Gentoo Linux][3] 系统的安装光盘和一本打印的说明书，要用它们来实现一个可运行的 Linux 系统。虽然花费了几天的时间去编辑和修整，但最终还是觉得自己受益颇多。
自此我再也没有转回 Windows 系统，但在持续的编译压力导致风扇失灵后，我将我的电脑系统切换到 [Arch Linux][4]。之后我将其他的电脑和私人服务器也切换到了 Arch Linux。作为一个滚动发布发行版，你可以随时升级软件包，但 [Arch Linux News][5] 已经详细报道了其中最主要的漏洞。
不过，令人烦恼的事一旦你更新了旧的内核模组， Arch Linux 就会移除旧版的相关信息。我经常注意到一旦我试着插入一个 USB 闪存驱动，内核就无法加载相关组件。相反，每次内核升级后都应该进行重启。有一些 [方法][6] 可以解决这个问题，但我还没有实际地使用它们。
其他程序也会出现类似的情况，通常 Firefox 、 cron 或者 Samba 在升级后都需要重启，但恼人的是，它们没有警告你存在这种情况不是提醒你这件事本身。我在工作中使用的 [SUSE][7] 很好地提醒了这种情况。
对于 [DDNet][8] ，我更喜欢使用 Arch Linux 的 [Debian][9] 系统，这样在每次升级时出现故障的几率更低。我的防火墙和路由器使用了拥有干净系统、文件和强大的 [OpenBSD][10] 的 [pf firewall][11]。
### 视窗管理
从我开始使用 Gentoo 后，我很快注意到 KDE 的编译时间非常长，这让我没办法继续使用它。我四处寻找更简单的解决方案，最初使用了 [Openbox][12] 和 [Fluxbox][13]。某次，为了能更多进行纯键盘操作，我开始转入平铺窗口管理器训练，并在研究其初始版本的时候学习了 [dwm][14] 和 [awesome][15]。
最终，由于 [xmonad][16]的灵活性，可扩展性以及使用纯 [Haskell][17] 一种出色的功能编程语言）编写和配置，最终选择了它。一个例子是，我在家中运行一个 40" 4K 的屏幕，但经常会将它分为四个虚拟屏幕，每个虚拟屏幕显示一个工作区，每个工作区自动排列在我的窗口上。 当然， xmonad 有一个对应的 [模块][18]。
[dzen][19] 和 [conky][20] 对我来说是一个非常简单的状态栏。我的整体conky配置看起来是这样的：
```
out_to_console yes
update_interval 1
total_run_times 0
TEXT
${downspeed eth0} ${upspeed eth0} | $cpu% ${loadavg 1} ${loadavg 2} ${loadavg 3} $mem/$memmax | ${time %F %T}
```
输入命令直接通过管道输入dzen2 `conky | dzen2 -fn '-xos4-terminus-medium-r-normal-*-12-*-*-*-*-*-*-*' -bg '#000000' -fg '#ffffff' -p -e '' -x 1000 -w 920 -xs 1 -ta r`.
对我而言，一项重要功能是在完成工作后使终端发出蜂鸣声。只需要简单地在 zsh 中的 `PR_TITLEBAR` 变量中添加一个 `\a` 字符就可以做到，只要工作完成就可以发出蜂鸣声。当然，我使用了 `echo "blacklist pcspkr" > /etc/modprobe.d/nobeep.conf` 命令，将 `pcspkr` 内核模块列入黑名单来禁用实际的蜂鸣声。相反 urxvt 的`URxvt.urgentOnBell: true` 设置会将声音变为尖锐。之后 xmonad 有一个 urgency hook 来捕捉这类信号，并且我可以使用组合键自动聚焦到当前紧急窗口。在 dzen 中我可以看到一个漂亮且明亮的 `#ff0000`紧急窗口。
在我笔记本上所得到的最终成品是：
[![Laptop screenshot][21]][22]
我听说前几年 [i3][23] 变得非常流行，但它要求更多的手动窗口对齐而不是自动对齐。
我意识到也有像 [tmux][24] 那样的终端多路复用器，但我仍想要一些图形化应用程序，因此最终我没有有效地使用它们。
### 终端连续性
为了使终端保持活跃状态，我使用了 [dtach][25] ，它只是模拟屏幕分离功能。 为了使计算机上的每个终端都可连接和断开，我编写了一个小的封装脚本。 这意味着，即使必须重新启动 X 服务器，我也可以使所有终端都运行良好，包括本地和远程终端。
### Shell & 编程
对于 shell，我使用 [zsh][28] 而不是 [bash][27]，因为它有众多的功能。
作为终端模拟，我发现 [urxvt][29] 足够轻巧，支持 Unicode 编码和 256 色，具有出色的性能。另一个重要的功能是可以分别运行 urxvt client 客户端和守护进程。因此，即使大量终端也几乎不占用任何内存（ scrollback 除外）。
对我而言，只有一种字体看起来绝对干净和完美： [Terminus][30]。 由于我是位图字体，因此所有内容都是完美像素，渲染速度极快且 CPU 使用率低。为了能使用 `CTRL-WIN-[1-7]` 在每个终端按需切换字体，我的 ~/.Xdefaults 包含:
```
URxvt.font: -xos4-terminus-medium-r-normal-*-14-*-*-*-*-*-*-*
dzen2.font: -xos4-terminus-medium-r-normal-*-14-*-*-*-*-*-*-*
URxvt.keysym.C-M-1: command:\033]50;-xos4-terminus-medium-r-normal-*-12-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-2: command:\033]50;-xos4-terminus-medium-r-normal-*-14-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-3: command:\033]50;-xos4-terminus-medium-r-normal-*-18-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-4: command:\033]50;-xos4-terminus-medium-r-normal-*-22-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-5: command:\033]50;-xos4-terminus-medium-r-normal-*-24-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-6: command:\033]50;-xos4-terminus-medium-r-normal-*-28-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-7: command:\033]50;-xos4-terminus-medium-r-normal-*-32-*-*-*-*-*-*-*\007
URxvt.keysym.C-M-n: command:\033]10;#ffffff\007\033]11;#000000\007\033]12;#ffffff\007\033]706;#00ffff\007\033]707;#ffff00\007
URxvt.keysym.C-M-b: command:\033]10;#000000\007\033]11;#ffffff\007\033]12;#000000\007\033]706;#0000ff\007\033]707;#ff0000\007
```
对于编程和书写，我使用 [Vim][31] 语法高亮显示和 [ctags][32] 进行索引，以及一些带有 grep 、sed 和其他用于搜索和操作的常用终端窗口。这可能不像 IDE 那样舒适，可以实现更多的自动化。
Vim 的一个问题是你已经习惯了它的键映射，因此希望在任何地方都使用它们。
在 shell 功能不够强大时，[Python][33] 和 [Nim][34] 作为脚本语言也不错。
### 系统监控
[htop][35] （查看当前站点的后台运行，是托管服务器的实时视图）非常适合快速了解软件的当前运行状态。 [lm_sensors][36] 可以监控硬件温度、风扇和电压。 [powertop][37] 是一款由 Intel 发布的优秀省电小工具。 [ncdu][38] 可以交互式分析磁盘使用情况。
[nmap][39]、 iptraf-ng、 [tcpdump][40] 和 [Wireshark][41] 都是分析网络问题的基本工具。
当然还有很多更优秀的工具。
### 邮件 & 同步
在我的 home server 服务器上，我为自己所有的邮箱账号运行了 [fetchmail][42] 守护进程。Fetchmail 只检索收到的邮件并调用 [procmail][43]:
```
#!/bin/sh
for i in /home/deen/.fetchmail/*; do
FETCHMAILHOME=$i /usr/bin/fetchmail -m 'procmail -d %T' -d 60
done
```
配置非常简单，然后等待服务器通知我们有新的邮件：
```
poll imap.1und1.de protocol imap timeout 120 user "dennis@felsin9.de" password "XXX" folders INBOX keep ssl idle
```
我的 `.procmailrc` 配置包含一些备份全部邮件的规则，并将邮件整理在对应的目录下面。例如，基于邮件列表名或者邮件标题：
```
MAILDIR=/home/deen/shared/Maildir
LOGFILE=$HOME/.procmaillog
LOGABSTRACT=no
VERBOSE=off
FORMAIL=/usr/bin/formail
NL="
"
:0wc
* ! ? test -d /media/mailarchive/`date +%Y`
| mkdir -p /media/mailarchive/`date +%Y`
# Make backups of all mail received in format YYYY/YYYY-MM
:0c
/media/mailarchive/`date +%Y`/`date +%Y-%m`
:0
* ^From: .*(.*@.*.kit.edu|.*@.*.uka.de|.*@.*.uni-karlsruhe.de)
$MAILDIR/.uni/
:0
* ^list-Id:.*lists.kit.edu
$MAILDIR/.uni-ml/
[...]
```
我使用 [msmtp][44] 来发送邮件，它也很好配置：
```
account default
host smtp.1und1.de
tls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
auth on
from dennis@felsin9.de
user dennis@felsin9.de
password XXX
[...]
```
但是到目前为止，邮件还在服务器上。 我的文档全部存储在一个目录中，我使用 [Unison][45] 在所有计算机之间进行同步。将 Unison 视为双向交互 [rsync][46]，我的邮件是这个文件目录下的一部分因此它们最终存储在我的电脑上。
这也意味着，尽管邮件会立即到达我的邮箱，但我只是按需拿取，而不是邮件一到达时就立即收到通知。
从此我使用 [mutt][47] 阅读邮件，使用侧边栏显示我的邮件目录。 `/etc/mailcap` 文件对于显示非纯文本邮件（ HTML, Word 或者 PDF）不可或缺：
```
text/html;w3m -I %{charset} -T text/html; copiousoutput
application/msword; antiword %s; copiousoutput
application/pdf; pdftotext -layout /dev/stdin -; copiousoutput
```
### 新闻 & 通讯
[Newsboat][48] 是一个非常棒的终端 RSS/Atom 阅读器。我在一个有约 150 个提要的 `tach` 会话服务器上运行它。也可以在本地选择提要，例如：
```
ignore-article "https://forum.ddnet.tw/feed.php" "title =~ \"Map Testing •\" or title =~ \"Old maps •\" or title =~ \"Map Bugs •\" or title =~ \"Archive •\" or title =~ \"Waiting for mapper •\" or title =~ \"Other mods •\" or title =~ \"Fixes •\""
```
我以同样的方式使用 [Irssi][49] 进行 IRC 通讯。
### 日历
[remind][50] 是一个可以从命令行获取的日历。通过编辑 `rem` 文件可以设置新的提醒：
```
# One time events
REM 2019-01-20 +90 Flight to China %b
# Recurring Holidays
REM 1 May +90 Holiday "Tag der Arbeit" %b
REM [trigger(easterdate(year(today()))-2)] +90 Holiday "Karfreitag" %b
# Time Change
REM Nov Sunday 1 --7 +90 Time Change (03:00 -> 02:00) %b
REM Apr Sunday 1 --7 +90 Time Change (02:00 -> 03:00) %b
# Birthdays
FSET birthday(x) "'s " + ord(year(trigdate())-x) + " birthday is %b"
REM 16 Apr +90 MSG Andreas[birthday(1994)]
# Sun
SET $LatDeg 49
SET $LatMin 19
SET $LatSec 49
SET $LongDeg -8
SET $LongMin -40
SET $LongSec -24
MSG Sun from [sunrise(trigdate())] to [sunset(trigdate())]
[...]
```
遗憾的是，目前 remind 中还没有中国农历的提醒功能，因此中国的节日不易计算。
我给提醒设置了两个名字：
```
rem -m -b1 -q -g
```
按时间顺序查看待办事项清单
```
rem -m -b1 -q -cuc12 -w$(($(tput cols)+1)) | sed -e "s/\f//g" | less
```
显示适应终端宽度的日历：
![remcal][51]
### 字典
[rdictcc][52] 是鲜为人知的字典工具，它可以从 [dict.cc][53] 使用高级词典并将他们转存在本地数据库中：
```
$ rdictcc rasch
====================[ A => B ]====================
rasch:
- apace
- brisk [speedy]
- cursory
- in a timely manner
- quick
- quickly
- rapid
- rapidly
- sharpish [Br.] [coll.]
- speedily
- speedy
- swift
- swiftly
rasch [gehen]:
- smartly [quickly]
Rasch {n} [Zittergras-Segge]:
- Alpine grass [Carex brizoides]
- quaking grass sedge [Carex brizoides]
Rasch {m} [regional] [Putzrasch]:
- scouring pad
====================[ B => A ]====================
Rasch model:
- Rasch-Modell {n}
```
### 记录和阅读
我有一个简单记录任务的备忘录，在 Vim 会话中基本上一直处于打开状态。我也使用备忘录作为工作中已做工作的记录，这样就可以检查自己每天完成了哪些任务。
对于写文件，信件和演示文稿，我会使用 [LaTeX][54] 进行高级排版。德式的简单信件可以这样设置，例如：
```
\documentclass[paper = a4, fromalign = right]{scrlttr2}
\usepackage{german}
\usepackage{eurosym}
\usepackage[utf8]{inputenc}
\setlength{\parskip}{6pt}
\setlength{\parindent}{0pt}
\setkomavar{fromname}{Dennis Felsing}
\setkomavar{fromaddress}{Meine Str. 1\\69181 Leimen}
\setkomavar{subject}{Titel}
\setkomavar*{enclseparator}{Anlagen}
\makeatletter
\@setplength{refvpos}{89mm}
\makeatother
\begin{document}
\begin{letter} {Herr Soundso\\Deine Str. 2\\69121 Heidelberg}
\opening{Sehr geehrter Herr Soundso,}
Sie haben bei mir seit dem Bla Bla Bla.
Ich fordere Sie hiermit zu Bla Bla Bla auf.
\closing{Mit freundlichen Grüßen}
\end{letter}
\end{document}
```
在 [我的私人网站][55] 上可以找到更多的示例文档和演示文稿。
[Zathura][56] 读取 PDF 文件速度很快，支持 Vim 类控件，还支持两种不同的 PDF 后端： Poppler 和 MuPDF。另一方面，在偶尔遇到 Zathura 无法打开的文件时，[Evince][57] 则显得更全能一些。
### 图片编辑
[GIMP][58] 和 [Inkscape][59] 分别是照片编辑和交互式向量图形是一个简便的选择。
有时 [Imagemagick][60] 已经足够好了，它可以从命令行直接使用，从而自动编辑图片。同样 [Graphviz][61] 和 [TikZ][62] 可以用来绘制曲线图和其他图表。
### 网络浏览器
对于网络浏览器，我一直在使用 [Firefox][63]。相较于 Chrome，它的可扩展性更好，资源使用率更低。
不幸的是，在 Firefox 完全改用 Chrome 风格的扩展之后， [Pentadactyl][64] l扩展的开发就停止了，所以我的浏览器中再也没有令人满意的 Vim 类控件了。
### 媒体播放器
通过设置 `vo=gpu` 以及 `hwdec=vaapi`，具有硬件解码功能的 [mpv][65] 在播放期间 CPU 的占用率保持在 5%。相较于默认的t PulseAudio，mpv 中的 `audio-channels=2` 似乎可以使我的立体扬声器/耳机获得更清晰的降级混频。一个很棒的小功能是用 `Shift-Q` 退出，而不是只用 `Q` 来保存回放位置。当你与母语是其他语言的人一起看视频时，你可以使用 `--secondary-sid=` 同时显示两种字幕，主字幕位于底部，次字幕位于屏幕顶部。
我的无线鼠标可以简单地通过一个小的配置文件（ `~/.config/mpv/input.conf` ）实现远程控制 mpv ：
```
MOUSE_BTN5 run "mixer" "pcm" "-2"
MOUSE_BTN6 run "mixer" "pcm" "+2"
MOUSE_BTN1 cycle sub-visibility
MOUSE_BTN7 add chapter -1
MOUSE_BTN8 add chapter 1
```
[youtube-dl][66] 非常适合观看在线托管的视频，使用 `-f bestvideo+bestaudio/best --all-subs --embed-subs` 命令可获得最高质量的视频。
作为音乐播放器， [MOC][67] 还未得到积极发展，但它仍是一个简易的播放器，可以播放各种可能的格式，包括最不常用的 Chiptune 格式。在 AUR 中有一个 [补丁][68] 增加了 PulseAudio 支持。即使在 CPU 时钟频率降到 800 MHz， MOC 也只使用了单核 CPU 的 1-2% 。
![moc][69]
我的音乐收藏夹保存在我的 home server 上，因此我可以从任何地方访问它。它使用 [SSHFS][70] 挂载并自动安装在 `/etc/fstab/` 目录下：
```
root@server:/media/media /mnt/media fuse.sshfs noauto,x-systemd.automount,idmap=user,IdentityFile=/root/.ssh/id_rsa,allow_other,reconnect 0 0
```
### 跨平台构建
除了系统本身，对于任何主流操作系统 Linux 在构建软件包方面都很优秀！ 一开始，我使用 [QEMU][71] 与旧版 Debian、 Windows 以及 Mac OS X VM 一起构建这些平台。
现在我在旧版 Debian distribution 上转而使用 chroot （以获得最大的 Linux 兼容性），在 Windows 上使用 [MinGW][72] 进行交叉编译，在 Mac OS X 上则使用 [OSXCross][73]。
用于 [build DDNet][74] 以及 [instructions for updating library builds][75] 的脚本都基于此。
### 备份
通常，我们都会忘记备份。即使这是终章，它也不应该成为事后诸葛。
十年前我写了 [rrb][76] （反向rsync备份）重新包装了 rsync ，因此我只需要授予正在备份的计算机，备份服务器的 root SSH 权限。令人惊讶地是，尽管我一直在使用 rrb ，但它在过去十年里没有任何改变。
备份文件直接存储在文件系统中。使用硬链接实现增量备份 (`--link-dest`) 。一个简单的 [配置][77] 定义了备份保存时间，默认为：
```
KEEP_RULES=( \
7 7 \ # One backup a day for the last 7 days
31 8 \ # 8 more backups for the last month
365 11 \ # 11 more backups for the last year
1825 4 \ # 4 more backups for the last 5 years
)
```
因为我的一些计算机没有静态 IP / DNS 但仍想使用 rrb 备份，那我会使用反向安全隧道（作为 systemd 服务）：
```
[Unit]
Description=Reverse SSH Tunnel
After=network.target
[Service]
ExecStart=/usr/bin/ssh -N -R 27276:localhost:22 -o "ExitOnForwardFailure yes" server
KillMode=process
Restart=always
[Install]
WantedBy=multi-user.target
```
现在，隧道运行备份时，服务器可以通过 `ssh -p 27276 localhost` 命令或者使用 `.ssh/config` 到达服务器端。
```
Host cr-remote
HostName localhost
Port 27276
```
在谈论 SSH 攻击时，有时由于某些中断的路由会很难访问到服务器。在那种情况下你可以借道其他服务器的 SSH 连接，以获得更好的路由。在这种情况下，你可能通过美国连接访问到我的中国服务器，而来自德国的不可靠连接可能需要几个周：
```
Host chn.ddnet.tw
ProxyCommand ssh -q usa.ddnet.tw nc -q0 chn.ddnet.tw 22
Port 22
```
### 结语
感谢阅读我工具的收藏。这其中我也许遗漏了许多日常中自然成习惯的步骤。让我们来看看我的软件设置在下一年里能多稳定吧。如果你有任何问题，随时联系我 [dennis@felsin9.de][78] 。
在 [Hacker News][79] 下评论吧。
