Linux 4.3 Kernel To Add The MOST Driver Subsystem
|
||||
================================================================================
|
||||
While the [Linux 4.2][1] kernel hasn't been officially released yet, Greg Kroah-Hartman sent in early his pull requests for the various subsystems he maintains for the Linux 4.3 merge window.
|
||||
|
||||
The pull requests sent in by Greg KH on Thursday include the Linux 4.3 merge window updates for the driver core, TTY/serial, USB driver, char/misc, and the staging area. These pull requests don't offer any really shocking changes but mostly routine work on improvements / additions / bug-fixes. The staging area once again is heavy with various fixes and clean-ups but there's also a new driver subsystem.
|
||||
|
||||
Greg mentioned of the [4.3 staging changes][2], "Lots of things all over the place, almost all of them trivial fixups and changes. The usual IIO updates and new drivers and we have added the MOST driver subsystem which is getting cleaned up in the tree. The ozwpan driver is finally being deleted as it is obviously abandoned and no one cares about it."
|
||||
|
||||
The MOST driver subsystem is short for the Media Oriented Systems Transport. The documentation to be added in the Linux 4.3 kernel explains, "The Media Oriented Systems Transport (MOST) driver gives Linux applications access a MOST network: The Automotive Information Backbone and the de-facto standard for high-bandwidth automotive multimedia networking. MOST defines the protocol, hardware and software layers necessary to allow for the efficient and low-cost transport of control, real-time and packet data using a single medium (physical layer). Media currently in use are fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST also supports various speed grades up to 150 Mbps." As explained, MOST is mostly about Linux in automotive applications.
|
||||
|
||||
While Greg KH sent in his various subsystem updates for Linux 4.3, he didn't yet propose the [KDBUS][5] kernel code be pulled. He's previously expressed plans for [KDBUS in Linux 4.3][3] so we'll wait until the 4.3 merge window officially gets going to see what happens. Stay tuned to Phoronix for more Linux 4.3 kernel coverage next week when the merge window will begin, [assuming Linus releases 4.2][4] this weekend.

How To Download Videos Using youtube-dl In Linux
|
||||
================================================================================
|
||||
|
||||
|
||||
I know you have already seen [how to download YouTube videos][1]. But those tools were mostly GUI ways. I am going to show you how to download YouTube videos via terminal using youtube-dl.
|
||||
|
||||
### [youtube-dl][2] ###
|
||||
|
||||
youtube-dl is a Python based small command-line tool that allows to download videos from YouTube.com, Dailymotion, Google Video, Photobucket, Facebook, Yahoo, Metacafe, Depositfiles and few more similar sites. It written in pygtk and requires Python interpreter to run this program, it’s not platform restricted. It should run on any Unix, Windows or in Mac OS X based systems.
|
||||
|
||||
The youtube-dl tool supports resuming interrupted downloads. If youtube-dl is killed (for example by Ctrl-C or due to loss of Internet connectivity) in the middle of download, you can simply re-run it with the same YouTube video url. It will automatically resume the unfinished download, as long as a partial download is present in the current directory. Which means, you don’t need a [download][3] manager for resuming downloads.
|
||||
|
||||
#### Installing youtube-dl ####
|
||||
|
||||
If you are running Ubuntu based Linux distribution, you can install it using this command:
|
||||
|
||||
sudo apt-get install youtube-dl
|
||||
|
||||
For any Linux distribution, you can quickly install youtube-dl on your system through the command line interface with:
|
||||
|
||||
sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O/usr/local/bin/youtube-dl
|
||||
|
||||
After fetching the file, you need to set a executable permission on the script to execute properly.
|
||||
|
||||
sudo chmod a+rx /usr/local/bin/youtube-dl
|
||||
|
||||
#### Use YouTube-DL to Download Videos: ####
|
||||
|
||||
To download a video file, simply run the following command. Where “VIDEO_URL” is the url of the video that you want to download.
|
||||
|
||||
youtube-dl VIDEO_URL
|
||||
|
||||
#### Download YouTube Videos in Multiple Formats: ####
|
||||
|
||||
These days YouTube videos have different resolutions, you first need to check available video formats of a given YouTube video. For that run youtube-dl with “-F” option. It will show you a list of available formats.
|
||||
|
||||
youtube-dl -F http://www.youtube.com/watch?v=BlXaGWbFVKY
|
||||
|
||||
It’s output will be like:
|
||||
|
||||
Setting language
|
||||
BlXaGWbFVKY: Downloading video webpage
|
||||
BlXaGWbFVKY: Downloading video info webpage
|
||||
BlXaGWbFVKY: Extracting video information
|
||||
Available formats:
|
||||
37 : mp4 [1080×1920]
|
||||
46 : webm [1080×1920]
|
||||
22 : mp4 [720×1280]
|
||||
45 : webm [720×1280]
|
||||
35 : flv [480×854]
|
||||
44 : webm [480×854]
|
||||
34 : flv [360×640]
|
||||
18 : mp4 [360×640]
|
||||
43 : webm [360×640]
|
||||
5 : flv [240×400]
|
||||
17 : mp4 [144×176]
|
||||
|
||||
Now among the available video formats, choose one that you like. For example, if you want to download it in MP4 version, you should use:
|
||||
|
||||
youtube-dl -f 17 http://www.youtube.com/watch?v=BlXaGWbFVKY
|
||||
|
||||
#### Download subtitles of videos using youtube-dl ####
|
||||
|
||||
First check if there are subtitles available for the video. To list all subs for a video, use the command beelow:
|
||||
|
||||
youtube-dl --list-subs https://www.youtube.com/watch?v=Ye8mB6VsUHw
|
||||
|
||||
To download all subs, but not the video:
|
||||
|
||||
youtube-dl --all-subs --skip-download https://www.youtube.com/watch?v=Ye8mB6VsUHw
|
||||
|
||||
#### Download entire playlist ####
|
||||
|
||||
To download a playlist, simply run the following command. Where “playlist_url” is the url of the playlist that ou want to download.
|
||||
|
||||
youtube-dl -cit playlist_url
|
||||
|
||||
youtube-dl is a versatile command line tool and provides a number of functionalities. No wonder it is such a popular command line tool.

How to Monitor Stock Prices from Ubuntu Command Line Using Mop
|
||||
================================================================================
|
||||
Having a side income is always good, especially when you can easily manage the work along with your full time job. If your regular work involves working on an Internet-connected computer, trading stocks is a popular option to earn a few extra bucks.
|
||||
|
||||
While there are quite a few stock-monitoring applications available for Linux, most of them are GUI-based. What if you’re a Linux professional who spends a lot (or all) of your time working on machines that do not have any GUI installed? Are you out of luck? Well, no, there are some command line stock-tracking tools, including Mop, which we’ll be discussing in this article.
|
||||
|
||||
### Mop ###
|
||||
|
||||
Mop, as already mentioned in the introduction above, is a command line tool that displays continuous and updated information about the US stock markets and individual stocks. Implemented in the GO programming language, the project is the brain child of Michael Dvorkin.
|
||||
|
||||
### Download and Install ###
|
||||
|
||||
Since the project is implemented in GO, before installing the tool, you’ll first have to make sure that the programming language is installed on your machine. Following are the steps required to install GO on a Debian-based system like Ubuntu:
|
||||
|
||||
sudo apt-get install golang
|
||||
mkdir ~/workspace
|
||||
echo 'export GOPATH="$HOME/workspace"' >> ~/.bashrc
|
||||
source ~/.bashrc
|
||||
|
||||
Once GO is installed, the next step is to install the Mop tool and set the environment, something which you can do by running the following commands:
|
||||
|
||||
sudo apt-get install git
|
||||
go get github.com/michaeldv/mop
|
||||
cd $GOPATH/src/github.com/michaeldv/mop
|
||||
make install
|
||||
export PATH="$PATH:$GOPATH/bin"
|
||||
|
||||
Once done, just run the following command to execute Mop:
|
||||
|
||||
cmd
|
||||
|
||||
### Features ###
|
||||
|
||||
When you run the Mop command for the first time, you’ll see an output similar to the following.
|
||||
|
||||
|
||||
|
||||
As you can see in the image above, the output – which auto-refreshes frequently – contains information related to various popular stock exchanges around the world as well as individual stocks.
|
||||
|
||||
### Add/remove stocks ###
|
||||
|
||||
Mop allows you to easily add/remove individual stocks to and from the output list. To add a stock, all you have to do is to press “+” and mention the stock listing name when prompted. For example, the following screenshot was taken while adding Facebook (FB) to the list.
|
||||
|
||||
|
||||
|
||||
As I pressed the “+” key, a row containing text “Add tickers:” appeared, prompting me to add the stock listing name – I added FB for Facebook and pressed Enter. The output refreshed, and the new stock was added to the list:
|
||||
|
||||
|
||||
|
||||
Similarly, you can delete a stock listing by pressing “-” and mentioning its name.
|
||||
|
||||
#### Group stocks based on value ####
|
||||
|
||||
There is a way to group stocks based on whether their value is going up or down – all you have to do is to press the “g” key. Following this, the stocks which are advancing will be grouped together and shown in green, while those whose value is going down will be represented in black.
|
||||
|
||||
Here is an example screenshot.
|
||||
|
||||
|
||||
|
||||
#### Column sort ####
|
||||
|
||||
Mop also allows you to change the sort order of individual columns. For this you first need to press “o” (this will select the first column by default), and then use the left and right arrow keys to select the column you want to sort. Once done, press enter to sort the column contents.
|
||||
|
||||
For example, the following screenshot shows the output after the contents of the first column were sorted in descending alphabetical order.
|
||||
|
||||
|
||||
|
||||
**Note**: to better understand, compare it with the previous screenshot.
|
||||
|
||||
#### Other options ####
|
||||
|
||||
Other available options include “p” for pausing market data and stock updates, “q” or “esc” for quitting the command line application, and “?” for displaying the help page.
|
||||
|
||||
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
Mop is a basic stock monitoring tool that doesn’t offer a plethora of features, but does what it promises. It’s quite obvious that the tool is not for stock trading professionals but is still a decent choice if all you want to do is some basic stock tracking on a command line-only machine.

How to Setup DockerUI - a Web Interface for Docker
|
||||
================================================================================
|
||||
Docker is getting more popularity day by day. The idea of running a complete Operating System inside a container rather than running inside a virtual machine is an awesome technology. Docker has made lives of millions of system administrators and developers pretty easy for getting their work done in no time. It is an open source technology that provides an open platform to pack, ship, share and run any application as a lightweight container without caring on which operating system we are running on the host. It has no boundaries of Language support, Frameworks or packaging system and can be run anywhere, anytime from a small home computers to high-end servers. Running docker containers and managing them may come a bit difficult and time consuming, so there is a web based application named DockerUI which is make managing and running container pretty simple. DockerUI is highly beneficial to people who are not much aware of linux command lines and want to run containerized applications. DockerUI is an open source web based application best known for its beautiful design and ease simple interface for running and managing docker containers.

How to Setup Red Hat Ceph Storage on CentOS 7.0
|
||||
================================================================================
|
||||
Ceph is an open source software platform that stores data on a single distributed computer cluster. When you are planning to build a cloud, then on top of the requirements you have to decide on how to implement your storage. Open Source CEPH is one of RED HAT mature technology based on object-store system, called RADOS, with a set of gateway APIs that present the data in block, file, and object modes. As a result of its open source nature, this portable storage platform may be installed and used in public or private clouds. The topology of a Ceph cluster is designed around replication and information distribution, which are intrinsic and provide data integrity. It is designed to be fault-tolerant, and can run on commodity hardware, but can also be run on a number of more advanced systems with the right setup.

为Linux 4.3 内核添加MOST 驱动子系统
|
||||
================================================================================
|
||||
当4.2 内核还没有正式发布的时候，Greg Kroah-Hartman 就为他维护的各种子系统模块打开了4.3 的合并窗口。
|
||||
|
||||
周二Greg KH 发起的拉取请求（pull request）里包含了linux 4.3 的合并窗口更新，内容涉及驱动核心、TTY/串口、USB驱动、字符/杂项以及暂存区内容。这些拉取申请没有提供任何震撼性的改变，大部分都是改进/附加/修改bug。暂存区内容又是大量的修正和清理，但是还是有一个新的驱动子系统。
|
||||
|
||||
|
||||
Greg 提到了[4.3 的暂存区改变][2]，“这里的很多东西，几乎全部都是细小的修改和改变。通常的IIO 更新和新驱动，以及我们已经添加了的MOST 驱动子系统，已经在源码树里整理了。ozwpan 驱动最终还是被删掉，引文它很明显被废弃了而且也没有人关心它。”
|
||||
|
||||
MOST 驱动子系统是面向媒体的系统传输的简称。在linux 4.3 新增的文档里面解释道，“MOST 驱动支持LInux 应用程序访问MOST 网络：汽车信息骨干网和高速汽车多媒体网络的事实上的标准。MOST 定义了必要的协议、硬件和软件层，提供高效且低消耗的传输控制，实时的数据包传输，只需要使用一个媒介（物理层）。目前使用的媒介是光线、非屏蔽双绞线（UTP）和同轴电缆。MOST 也支持多种传输速度，最高支持150Mbps。”如文档解释的，MOST 主要是关于Linux 在汽车上的应用。
|
||||
|
||||
当Greg KH 发出了他为Linux 4.3 多个子系统做出的更新，但是他还没有打算提交[KDBUS][5]的内核代码。他之前已经放出了[linux 4.3 的KDBUS] 的开发计划，所以我们将需要等待官方的4.3 合并窗口，看看会发生什么。关注Phoronix 下周关于linux 4.3 内核的新闻报道，此时合并窗口将会开始，假如Linus 在本周[发布linux 4.2][4]。

如何在 Linux 中使用 youtube-dl 下载视频
|
||||
================================================================================
|
||||
|
||||
|
||||
我知道你已经看过[如何下载 YouTube 视频][1]。但那些工具大部分都采用图形用户界面的方式。我会向你展示如何通过终端使用 youtube-dl 下载 YouTube 视频。
|
||||
|
||||
### [youtube-dl][2] ###
|
||||
|
||||
youtube-dl 是基于 Python 的命令行小工具，允许你从 YouTube.com、Dailymotion、Google Video、Photobucket、Facebook、Yahoo、Metacafe、Depositfiles 以及其它一些类似网站中下载视频。它是用 pygtk 编写的，需要 Python 解析器来运行，对平台要求并不严格。它能够在 Unix、Windows 或者 Mac OS X 系统上运行。
|
||||
|
||||
youtube-dl 支持断点续传。如果在下载的过程中 youtube-dl 被杀死了（例如通过 Ctrl-C 或者丢失网络连接），你只需要使用相同的 YouTube 视频 URL 再次运行它。只要当前目录中有下载的部分文件，它就会自动恢复没有完成的下载，也就是说，你不需要[下载][3]管理器来恢复下载。
|
||||
|
||||
#### 安装 youtube-dl ####
|
||||
|
||||
如果你运行的是基于 Ubuntu 的 Linux 发行版，你可以使用下面的命令安装：
|
||||
|
||||
sudo apt-get install youtube-dl
|
||||
|
||||
对于任何 Linux 发行版，你都可以通过下面的命令行接口在你的系统上快速安装 youtube-dl：
|
||||
|
||||
sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O/usr/local/bin/youtube-dl
|
||||
|
||||
获取到该文件后，为了能正常执行你需要给脚本设置可执行权限。
|
||||
|
||||
sudo chmod a+rx /usr/local/bin/youtube-dl
|
||||
|
||||
#### 使用 youtube-dl 下载视频： ####
|
||||
|
||||
要下载一个视频文件，只需要运行下面的命令。其中 “VIDEO_URL” 是你想要下载视频的 url。
|
||||
|
||||
youtube-dl VIDEO_URL
|
||||
|
||||
#### 以多种格式下载 YouTube 视频： ####
|
||||
|
||||
现在 YouTube 视频有不同的分辨率，首先你需要检查指定的 YouTube 视频可用的视频格式。可以使用 “-F” 选项运行 youtube-dl。它会向你显示出可用的格式。
|
||||
|
||||
youtube-dl -F http://www.youtube.com/watch?v=BlXaGWbFVKY
|
||||
|
||||
它的输出类似于：

18 : mp4 [360×640]
|
||||
43 : webm [360×640]
|
||||
5 : flv [240×400]
|
||||
17 : mp4 [144×176]
|
||||
|
||||
在可用的视频格式中，选择你需要的一种。例如，如果你想下载 MP4 格式的，你可以：
|
||||
|
||||
youtube-dl -f 17 http://www.youtube.com/watch?v=BlXaGWbFVKY
|
||||
|
||||
#### 使用 youtube-dl 下载视频字幕 ####
|
||||
|
||||
首先检查是否有可用的视频字幕。使用下面的命令列出视频所有可用的字幕：
|
||||
|
||||
youtube-dl --list-subs https://www.youtube.com/watch?v=Ye8mB6VsUHw
|
||||
|
||||
下载所有字幕，但不包括视频：
|
||||
|
||||
youtube-dl --all-subs --skip-download https://www.youtube.com/watch?v=Ye8mB6VsUHw
|
||||
|
||||
#### 下载整个播放列表 ####
|
||||
|
||||
运行下面的命令下载整个播放列表。其中 “playlist_url” 是你希望下载的播放列表的 url。
|
||||
|
||||
youtube-dl -cit playlist_url
|
||||
|
||||
youtube-dl 是一个多功能的命令行工具，它提供了很多功能。难怪这个命令行工具这么流行。

命令行下使用Mop 监视股票价格
|
||||
================================================================================
|
||||
有一份隐性收入通常很不错，特别是当你可以轻松的协调业余和全职工作。如果你的日常工作使用了联网的电脑，交易股票是一个很流行的选项来获取额外收入。
|
||||
|
||||
但是目前只有很少的股票监视软件可以用在linux 上，其中大多数还是基于图形界面的。如果你是一个Linux 专家，并且大量的工作时间是在没有图形界面的电脑上呢？你是不是就没办法了？不，这里还有一个命令行下的股票追踪工具，包括Mop，也就是本文要聊一聊的工具。
|
||||
### Mop ###
|
||||
|
||||
Mop，如上所述，是一个命令行下连续显示和更新美股和独立股票信息的工具。使用GO 实现的，是Michael Dvorkin 大脑的产物。
|
||||
### 下载安装 ###
|
||||
|
||||
|
||||
因为这个工程使用GO 实现的，所以你要做的第一步是在你的计算机上安装这种编程语言，下面就是在Debian 系系统，比如Ubuntu上安装GO的步骤：
|
||||
|
||||
sudo apt-get install golang
|
||||
mkdir ~/workspace
|
||||
echo 'export GOPATH="$HOME/workspace"' >> ~/.bashrc
|
||||
source ~/.bashrc
|
||||
|
||||
GO 安装好后的下一步是安装Mop 工具和配置环境，你要做的是运行下面的命令：
|
||||
|
||||
sudo apt-get install git
|
||||
go get github.com/michaeldv/mop
|
||||
cd $GOPATH/src/github.com/michaeldv/mop
|
||||
make install
|
||||
export PATH="$PATH:$GOPATH/bin"
|
||||
|
||||
完成之后就可以运行下面的命令执行Mop：
|
||||
cmd
|
||||
|
||||
### 特性 ###
|
||||
|
||||
当你第一次运行Mop 时，你会看到类似下面的输出信息：
|
||||
|
||||
|
||||
|
||||
如你所见，这些输出信息—— 周期性自动刷新 ——包含了主要几个交易所和个股的信息。
|
||||
|
||||
### 添加删除股票 ###
|
||||
|
||||
Mop 允许你轻松的从输出列表上添加/删除个股信息。要添加，你全部要做的是按”+“和输入股票名称。举个例子，下图就是添加Facebook (FB) 到列表里。
|
||||
|
||||
|
||||
|
||||
因为我按下了”+“键，一列包含文本”Add tickers：“出现了，提示我添加股票名称—— 我添加了FB 然后按下回车。输出列表更新了，我添加的新股票也出现在列表了：
|
||||
|
||||
|
||||
|
||||
类似的，你可以使用”-“ 键和提供股票名称删除一个股票。
|
||||
|
||||
#### 根据价格分组 ####
|
||||
|
||||
还有一个把股票分组的办法：依据他们的股价升跌，你索要做的就是按下”g“ 键。接下来，股票会分组显示：升的在一起使用绿色字体显示，而下跌的股票会黑色字体显示。
|
||||
|
||||
如下所示：
|
||||
|
||||
|
||||
|
||||
#### 列排序 ####
|
||||
|
||||
Mop 同时也允许你根据不同的列类型改变排序规则。这种用法需要你按下”o“（这个命令默认使用第一列的值来排序），然后使用左右键来选择你要使用的列。完成之后按下回车对内容重新排序。
|
||||
|
||||
举个例子，下面的截图就是根据输出内容的第一列、按照字母表排序之后的结果。
|
||||
|
||||
|
||||
|
||||
**注意**: 为了更好的理解，和前面的截屏对比一下。
|
||||
|
||||
#### 其他选项 ####
|
||||
|
||||
其它的可用选项包括”p“：暂停市场和股票信息更新，”q“ 或者”esc“ 来退出命令行程序，”？“ 显示帮助页。
|
||||
|
||||
|
||||
### 结论 ###
|
||||
|
||||
Mop 是一个基础的股票监控工具，并没有提供太多的特性，只提供了他声称的功能。很明显，这个工具并不是为专业股票交易者提供的，而仅仅为你在只有命令行的机器上得体的提供了一个跟踪股票信息的选择。
