XS Leaks using disk cache grooming

The admin bot creates a new browsing context with createBrowsingContext() and uses that to create a page. Each browsing context should have a dedicated disk cache but how does chrome handle this? I deduced that it uses in-memory disk cache and it's much smaller than the default on-disk disk cache. The incognito tab of my browser has the same behavior.

The following page alerts "not cached" due to cache miss in incognito mode but no error happens in a regular tab.

$ cat <<EOF > index.html

# X.Org 任意窗口划词翻译
# 在 DE/WM 中设置快捷键执行
# 分单词和句子两种模式，notification 中显示的都是 Google 翻译的结果，但单词附带百度翻译的链接，句子附带 Google 翻译的链接
# notification 中附带的链接是否能点开依赖于 notification daemon，dunst 需要在设置中的 `mouse_left_click` 处加上 `open_url`
# 翻译的单词连同日期和窗口标题会记录在 ~/.cache/translated-words.txt
# 可以使用 http_proxy 环境变量设置代理
# notification 的 appname 是 "xorg-translate"，在 dunst 中可以对其进行配置，例如设置图标

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just
