ubuntu 安装后wifi无法使用

2022-01-11

tech
原文件是ubuntu16.04安装了octopress2.0，升级到ubuntu18.04，新建此文件，可以运行，没报错，然后改成这个内容

首先利用rfkill命令查看目前无线传输设备的状态，rfkill是一个命令行工具，可使用它查询和更改系统中启用了RFKill的设备。

rfkill的常用方法为:
```
rfkill list all
#  获得设备列表

rfkill block [index|type]
#  通过索引或类型禁用设备

rfkill unblock [index|type]
#  通过索引或类型启用设备
```
当前设备状态如下：
```
rfkill list all
输出：
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes
1: acer-wireless: Wireless LAN
	Soft blocked: no
	Hard blocked: no
```
通过rfkill启用/禁用设备无法对硬件阻塞产生作用。

由于笔记本只有一个无线网卡，这两个模块应该是有冲突

使用命令lsmod grep acer可以看出系统启动了acer_wmi模块

通过查找资料后，解决方法为禁用acer_wmi模块。

ubuntu 16.04 install octopress 2.0

2022-01-11

tech-octopress
ubuntu20.04安装了几次2.0都失败
ubuntu12.04已经无法安装系统本身的更新了，更别说安装其他软件
强迫症发作，于是有了这次：

列出大致步骤吧，主要是有些error要如何解决

git

install git
```
git --version
sudo apt install git
git --version
```
set up git

Username

github用户名
```
git config --global user.name "qiuhaidong"
#or haydnyau
```
Email

github登录帐号邮箱名
```
git config --global user.email "690982322@qq.com"
#or 1148891016@qq.com
```
Password caching

To use this option, you need to turn on the credential helper so that git will save your password in memory for some time:
```
git config --global credential.helper cache
```
添加 SSH Keys

Step 1: Check for SSH keys

First, we need to check for existing ssh keys on your computer. Open up Terminal and run:
```
cd ~/.ssh
# Checks to see if there is a directory named ".ssh" in your user directory
```
If it says “No such file or directory” go to step 2. Otherwise, you already have an existing keypair, and you can skip to step 3.

最好就是把 .shh 这个文件夹删除了，做step 2

Step 2: Generate a new SSH key

To generate a new SSH key, enter the code below. We want the default settings so when asked to enter a file in which to save the key, just press enter.不要输入文件名
```
ssh-keygen -t rsa -C "your_email@example.com"
我的就是：ssh-keygen -t rsa -C "690982322@qq.com"
#or 1148891016@qq.com
```
Now you need to enter a passphrase.设置密码。（有人是密码都不要的，再按两下enter就行了）

Which should give you something like this:
```
Your identification has been saved in /home/you/.ssh/id_rsa.
Your public key has been saved in /home/you/.ssh/id_rsa.pub.
The key fingerprint is:
01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db your_email@example.com
```
Step 3: Add your SSH key to GitHub

ctrl+h，显示隐藏文件，这里其实可以打开这个id_rsa.pub文件，直接复制，不用安装下面的软件
```
sudo apt-get install xclip
# Downloads and installs xclip.

xclip -sel clip < ~/.ssh/id_rsa.pub
# Copies the contents of the id_rsa.pub file to your clipboard
```
Add your SSH key to GitHub

到github网站，登陆，头像，设置，SSH and GPG keys，把旧的SSH keys删除，添加新的，title不用管，粘贴到key就行了

Step 4: Test
```
ssh -T git@github.com
```
这里可能会还要按照提示做一下，不难，看英文做

如果看到：
```
Hi qiuhaidong! You've successfully authenticated, but GitHub does not provide shell access.
# or haydnyau
```
If that username is correct, you’ve successfully set up your SSH key. Don’t worry about the shell access thing, you don’t want that anyway.

If you see “access denied” please consider using HTTPS instead of SSH. If you need SSH start at these instructions for diagnosing the issue.

如果不成功，用https的认证方式代替ssh，因为github觉得ssh不安全，认证方式有时会改变

RVM

看官网命令
```
rvm --version
gpg2 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
```
会显示失败，先不管它
Install RVM：命令
```
curl -sSL https://get.rvm.io | bash -s stable
```
如下：
```
dong@Ubuntu:~$ curl -sSL https://get.rvm.io | bash -s stable
Downloading https://github.com/rvm/rvm/archive/1.29.12.tar.gz

    gpg2 --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
or if it fails:
    command curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
    command curl -sSL https://rvm.io/pkuczynski.asc | gpg2 --import -
In case of further problems with validation please refer to https://rvm.io/rvm/security
```
这个提示错误，并且给出了解决方法：
运行：
命令1：
```
curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
```
命令2：
```
curl -sSL https://rvm.io/pkuczynski.asc | gpg2 --import -
```
再运行上一条命令安装rvm：
```
curl -L https://get.rvm.io | bash -s stable
```
输出：
```
  * To start using RVM you need to run `source /home/dong/.rvm/scripts/rvm`
```
安装成功，按照提示运行：
```
source /home/dong/.rvm/scripts/rvm
```
测试：
```
rvm --version
git --version
```
安装ruby2.2.6（1.9.3太久了，无法安装）
```
rvm install 2.2.6
```
会提示输入本机密码
```
rvm use 2.2.6
```
Setup Octopress
```
git clone -b source git@github.com:qiuhaidong/qiuhaidong.github.com.git octopress
# 或者 git clone git://github.com/imathis/octopress.git octopress
# octopress  2.0 原码
cd octopress
```
install dependencies
```
gem install bundler
```
会提示失败，按提示加上版本号，安装适合本系统的
```
bundle install
```
Install the default Octopress theme
```
rake install
```
Deploying to Github Pages
```
rake setup_github_pages
```
这里可能会要输入链接等，ssh，https

The rake task will ask you for a URL of the Github repo. Copy the SSH or HTTPS URL from your newly created repository
(e.g. git@github.com:username/username.github.io.git)
git@github.com:qiuhaidong/qiuhaidong.github.com.git
https://github.com/qiuhaidong/qiuhaidong.github.com.git
or
git@github.com:haydnyau/haydnyau.github.io.git
https://github.com/haydnyau/haydnyau.github.io.git
and paste it in as a response.

This will:
1. Ask for and store your Github Pages repository url.
2. Rename the remote pointing to imathis/octopress from ‘origin’ to ‘octopress’
3. Add your Github Pages repository as the default origin remote.
4. Switch the active branch from master to source.
5. Configure your blog’s url according to your repository.
6. Setup a master branch in the _deploy directory for deployment.
Next run:
```
rake generate
rake deploy
```
This will generate your blog, copy the generated files into _deploy/, add them to git, commit and push them up to the master branch. In a few seconds you should get an email from Github telling you that your commit has been received and will be published on your site.

=======================================================

来自官网
下面这个不知道要不要做：
Now you have a place to commit the generated content for your site, but you should also set up repository to store the source for your blog. After you set up a repository for your blog source, add it as the origin remote.
```
git remote add origin (your repo url)
# set your new origin as the default branch
git config branch.master.remote origin
```
Now push your changes and you’ll be all set.

========================================================

Don’t forget to commit the source for your blog.

git add .
git commit -m 'update'
git push origin source

侧边栏增加分类 category

2022-01-10

tech-octopress

octopress2.0

三步

Step 1

添加 `category_list` 插件

在 octopress\plugins\ 文件夹里面，新建一个文件，名为：category_list_tag.rb。并将下面的代码粘贴到里面。

module Jekyll
  class CategoryListTag < Liquid::Tag
    def render(context)
      html = ""
      categories = context.registers[:site].categories.keys
      categories.sort.each do |category|
        posts_in_category = context.registers[:site].categories[category].size
 	       category_dir = context.registers[:site].config['category_dir']
        category_url = File.join(category_dir, category.gsub(/_|\P{Word}/, '-').gsub(/-{2,}/, '-').downcase)
    	html << "<li class='category'><a href='/#{category_url}/'>#{category} (#{posts_in_category})</a></li>\n"
      end
      html
    end
  end
end

Liquid::Template.register_tag('category_list', Jekyll::CategoryListTag)

这个插件会向liquid注册一个名为category_list的tag，该tag就是以li的形式将站点所有的category组织起来。如果要将category加入到侧边导航栏，需要增加一个aside。

Step 2

增加 `aside`

在 octopress\source\_includes\asides\ 文件夹里面，新建一个文件，名为：category_list.html 。并粘贴下面的代码：

注意：去掉 % 前面的2个 \
这里如果不加上\，markdown格式会显示category_list的内容。我是为了正确显示代码才加上的

<section>
  <h1>Categories</h1>
  <ul id="categories">
    {\% category_list \%}
  </ul>
</section>

原因：

回答1：

This happens because webrick is no longer a bundled gem in Ruby 3.0. From https://www.ruby-lang.org/en/news/2020/12/25/ruby-3-0-0-released/:

The following libraries are no longer bundled gems or standard libraries. Install the corresponding gems to use these features.

sdbm

webrick

net-telnet

xmlrpc

Adding gem "webrick" to my Gemfile solves the problem, but Jekyll should include it in its gemspec.

回答2：

I think you want run: bundle add webrick.

我运行：

sudo bundle add webrick

今晚
并不是说命中率最高、速度最快，而是心态最好，进入境界。
就像麦迪说的，35秒13分并不是他的最好，他的最好是进入了“in the zone”的境界。
我今晚也一样。
具体这样说吧：
心跳如常，不为任何情况所动，该怎样怎样。
进攻：
该跑跑，该停停，该切切，该快快，该慢慢。
该投投，不犹豫。
该晃晃，该突突，该传传，该断断。
防守：
该紧紧，该松松。
被背打就被背打，不懊恼。
能帽帽，不喜不惧。
其他：
投不进就不进，不懊恼，不可惜，继续。
失误就失误，继续。
开场还是抢七，该怎样怎样。
不怕强劲的对手，不怕拖累队友。
心态控制体能，微汗。

这一年，三件事：到京东打工，学做饭，耳朵生病。
打工
是做苦力，卖力气，很丢人，但，荒废了两年，终于动了。具体的，以前写过，不重复。
做饭
很有门道，比如炒青菜，刚下锅，有的马上熟了，有的还没炒到，心慌。淡定，正常翻炒，就行了。还有先炒猪肉，再放面去炒，再放青菜，看起来一大锅，怕青菜在上面炒不熟，慌了。淡定，正常翻炒，就行了。
淡定，正常地做，就行了。
生病
对自己太狠。秋冬，连续俩月通宵夜班，噪声大，有压力，情绪不稳定，早上洗冷水澡，重糖，重淀粉（米面主食），重油，重盐，吃辣椒，估计血糖高，血脂高，血压高，血粘稠，睡眠严重不足，內耳供血不足，听觉神经长期疲累不堪。免疫力下降，感冒，鼻塞，咽鼓管之类的不通畅。
种种原因，祸不单行，差点聋了。
就这三件事。
吸取教训，放下执念，放过自己，好好生活。
