参照github上的问答，在 typecho 网站空间内 /usr/themes/default 放入了下载好的文件 normalize.css。

然后 控制台->外观->编辑当前外观->header.php：

<!-- 使用url函数转换相关路径 --> 的下一行，将其更改为了

<link rel="stylesheet" href="<?php $this->options->themeUrl('normalize.css'); ?>">

之后保存成功即可生效。

在本指南中，我们将了解如何将 LocalDate 转换为 Date。在查看转换代码之前，让我们先看看 Date 和 LocalDate 之间有什么区别。

java.util.Date - date + time + timezone
java.time.LocalDate - only date

因此，要将 LocalDate 转换为 Date，我们必须在日期后附加时间和时区信息。考虑到这一点，转换步骤如下：

1. 获取默认时区，以便在日期中附加时区信息
2. 调用 atStartOfDay()，以便将时间与日期附加在一起
3. LocalDate to Date - local date + atStartOfDay() + 默认时区(default time zone) + toInstant() = Date

As nobody answered, So I asked this on MongoDB-User Group

Say cars is your outputcollection (where you want to store output of map-reduce job).

• REPLACE: If your current MR is successful, all of the documents in cars will be deleted (regardless of their _id) and replaced by the current result.

• MERGE: No document in cars will be deleted. Instead, each document in your current result will replace an already existing document in cars with the same _id. If there is not any document in cars with that _id, it will be just inserted. You can see this like an upsert:

  db.cars.update({_id: newDocument._id}, {value: newDocument.value}, {upsert: true})

• REDUCE: This is very similar to MERGE. But instead of just replacing the existing document, both documents will be the input of your reduce function (i.e. reduce([oldDocument, newDocument])) and the resulting document will replace the existing one.
• INLINE: Returns your result as a variable in the same fashion a function does. Nothing is stored in MongoDB, so this does not impact any collection.

The complete answer can be found here.

Do not bind to a specific port. Instead, bind to port 0:

sock.bind(('', 0))

The OS will then pick an available port for you. You can get the port that was chosen using sock.getsockname()[1], and pass it on to the slaves so that they can connect back.

import socket
from contextlib import closing

def find_free_port():
    with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as s:
        s.bind(('', 0))
        s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        return s.getsockname()[1]

利用 typecho 上传文件（附件）时，提示上传失败。

环境

Ubuntu 16.04
typecho 1.1
PHP7.0
Nginx

失败的原因

• PHP 限制了上传文件的大小
• Nginx 限制了上传文件的大小

现目前在网上能够搜索到的信息，90%的都只提到了错误原因是由PHP的配置文件引起的，我看到的就一篇文章(参考文献2)提到了Nginx的问题，并在其文章的帮助使得我将问题有效地解决掉了，在此表示感谢。
