  1. 双拼
    • 选择输入法的哲学：兼论双拼的优缺点 - 少数派
      • 录入文字的过程可以简单分为两个环节：1. 大脑将思考的内容转化为可以通过键盘录 入的内容（比如字形、字音）；2. 通过键盘将字形或字音录入电脑并组合为最终文字。
      • 我们的大脑更容易把思维转化为声音而不是文字 ，甚至有很多人必须先把思维转化 为声音然后才能进一步转化为文字：我们见过很多人在输入的时候嘴里念念有词，这就 是通过声音来辅助文字呈现的一种方式，但我们从来没见过有人说话的时候，需要拿支 笔边写边说。
      • 双拼输入法是拼音输入法的一种，因此它继承了拼音输入法在第一环节的优势；而由于 简化了复合声母和韵母，在第二环节的效率追平甚至超过了五笔输入法。

  • 播客届的京派与海派 - 少数派

    时隔近百年，当下的中文播客圈，听众之中流行着一个说法，将中文播客分类为「陪伴型 / 湿货」和「硬核型 / 干货」两种类型。苹果发布的 2019 年最佳中文播客榜单中，不 乏「大内密谈」「日谈公园」「跟宇宙结婚」这样的「闲话类」陪伴型播客，也丰盈着 「忽左忽右」「博物志」「声东击西」「不可理论」等信息度相对密集、知识点充沛的播 客节目。前者往往以北京为核心，主要是北方语系；后者则以上海为中心，且基本有海外 背景。

    Jesse Chan (@Jesoooor) 言:

    独立 = 创作过程不受限制、影响。

    这个限制和影响可能来自资本、技术、商业、受众。但你不可能找到一个一刀切的标准来定义「独立」。

    小众厂牌 Spotify 独占，能叫独立音乐吗？微软独占的《Cuphead》叫独立游戏吗？

    这是要从内容本身出发去判断的，真正「独立」的内容会散发出独一无二的气质。

17.1.2 Tips

  • eval-after-load vs. mode hook - Stack Overflow

    Code wrapped in eval-after-load will be executed only once, so it is typically used to perform one-time setup such as setting default global values and behaviour. An example might be setting up a default keymap for a particular mode. In eval-after-load code, there’s no notion of the “current buffer”.

    Mode hooks execute once for every buffer in which the mode is enabled, so they’re used for per-buffer configuration. Mode hooks are therefore run later than eval-after-load code; this lets them take actions based upon such information as whether other modes are enabled in the current buffer.

  • The difference between setq and setq-default in Emacs Lisp

    Some variables in Emacs are “buffer-local”, meaning that each buffer is allowed to have a separate value for that variable that overrides the global default. tab-width is a good example of a buffer-local variable.

    If a variable is buffer-local, then setq sets its local value in the current buffer and setq-default sets the global default value.

    If a variable is not buffer-local, then setq and setq-default do the same thing.

17.3 Doom Emacs

My configuration .doom.d

17.3.2 Modules

  • term/vterm - +vterm/toggle (SPC o t): Toggle vterm pop up window in the current project

17.3.3 Hacks

  • Need doom/toggle-maximized command #397

    (add-to-list 'initial-frame-alist '(fullscreen . maximized))

  • modules/lang/org

    TAB was changed to toggle only the visibility state of the current subtree, rather than cycle through it recursively. This can be reversed with:

    (after! evil-org
  (remove-hook 'org-tab-first-hook #'+org-cycle-only-current-subtree-h))

  • Doom crashes when…

    On some systems (particularly MacOS), manipulating the fringes or window margins can cause Emacs to crash. This is most prominent in the Doom Dashboard (which tries to center its contents), in org-mode buffers (which uses org-indent-mode to create virtual indentation), or magit. There is currently no known fix for this, as it can’t be reliably reproduced. Your best bet is to reinstall/rebuild Emacs or disable the errant plugins/modules. e.g.

    To disable org-indent-mode:

    (after! org
  (setq org-startup-indented nil))

    Or disable the :ui doom-dashboard & :tools magit modules (see #1170).

18 Org Mode

18.1 Configuration

18.1.1 General

(setq org-export-with-sub-superscripts nil
      org-html-doctype "html5"
      org-html-html5-fancy t ; enable new block elements introduced with the HTML5 standard
      org-html-head-include-default-style nil
      org-html-htmlize-output-type 'css)

       org-want-todo-bindings t))

(defun dotspacemacs/user-config ()
  (with-eval-after-load 'org
    (setq ... )))

18.1.3 gongzhitaao/ orgcss

When exported to HTML, there are three options for code highlighting, controlled by the variable org-html-htmlize-output-type.

  1. (setq org-html-htmlize-output-type 'inline-css)

    This is the default setting. It highlights the code according to the current Emacs theme you are using. It directly applies color to the code with inline styles, e.g., <span style="color: 0x000000">int</span>.

    The problem is that the highlight theme depends on the Emacs theme. If you use a dark theme in your Emacs but a light theme (usually we like light themed web pages) web pages, the exported code are hardly illegible due to the light font color, or vice versa.

  2. (setq org-html-htmlize-output-type nil)

    This configuration disables highlighting by htmlize. You may use a third-party Javascript highlight library. I recommend highlight.js if I need code highlight.

    There are two problems:

    1. The problem is that you have to rely on highlight.js support on a certain language which is occasionally missing, e.g., emacs-lisp, org, etc.
    2. highlight.js by default does not recognized the tags and classes exported by org mode. You need some extra Javascript code in your Org file.

  3. (setq org-html-htmlize-output-type 'css)

    This is similar to the first optional, instead of using inline styles, this will assign classes to each component of the code, e.g., <span class="org-type">int</span>, and you could create your own stylesheet for .org-type.

    To obtain a list of all supported org classes, run M-x org-html-htmlize-generate-css. This will create a buffer containing all the available org style class names in the current Emacs session.

18.2 Hacks

  • org mode - Set the background of org-exported <code> blocks according to them…

    (defun my/org-inline-css-hook (exporter)
  "Insert custom inline css to automatically set the
background of code to whatever theme I'm using's background"
  (when (eq exporter 'html)
    (let* ((my-pre-bg (face-background 'default))
           (my-pre-fg (face-foreground 'default)))
      (setq
       org-html-head-extra
       (concat
        org-html-head-extra
        (format "<style type=\"text/css\">\n pre.src {background-color: %s; color: %s;}</style>\n"
                my-pre-bg my-pre-fg))))))

(add-hook 'org-export-before-processing-hook 'my/org-inline-css-hook)

    the same way to insert inline CSS or Javascript from local files:

    (defun my/org-inline-source-hook (exporter)
  (when (eq exporter 'html)
    (setq org-html-head-extra (concat

  • 改变 Launchpad 中应用图标的大小

    defaults write com.apple.dock springboard-columns -int 列数

21.2.2 Zsh

.zshenv is sourced on all invocations of the shell, unless the -f option is set. It should contain commands to set the command search path, plus other important environment variables. .zshenv should not contain commands that produce output or assume the shell is attached to a tty.

  • Use iconutil to Create an icns File Manually

    from stackoverflow.com/questions/12306223

    mkdir MyIcon.iconset

# convert a 1024x1024 png (named "Icon1024.png") to the required icns file
sips -z 16 16     Icon1024.png --out MyIcon.iconset/icon_16x16.png
sips -z 32 32     Icon1024.png --out MyIcon.iconset/[email protected]
sips -z 32 32     Icon1024.png --out MyIcon.iconset/icon_32x32.png
sips -z 64 64     Icon1024.png --out MyIcon.iconset/[email protected]

# 生成 dhparam.pem 文件, 在命令行执行任一方法:

# 方法1: 很慢
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

# 方法2: 较快
# 与方法1无明显区别. 2048位也足够用, 4096更强
openssl dhparam -dsaparam -out /etc/nginx/ssl/dhparam.pem 4096
