Which Raspberry Pi should you choose?
|
||||
======
|
||||
In the first article in our series on getting started with Raspberry Pi, learn the three criteria for choosing the right model for you.
|
||||
|
||||
|
||||
This is the first article in a 14-day series on getting started with the [Raspberry Pi][1]. Although the series is geared towards people who have never used a Raspberry Pi or Linux or programming, there will definitely be things for more experienced readers—and I encourage those readers to leave comments and tips that build on what I write. If everyone contributes, we can make this series even more useful for beginners, other experienced readers, and even me!
|
||||
|
||||
So, you want to give the Raspberry Pi a shot, but you don't know which model to buy. Maybe you want one for your classroom or your kid, but there are so many options, and you aren't sure which one is right for you.
|
||||
|
||||
|
||||
|
||||
My three main criteria for choosing a new Raspberry Pi are:
|
||||
|
||||
* **Cost:** Don't just consider the cost of the Raspberry Pi board, but also factor the peripherals you will need in order to use it. In the US, the Raspberry Pi's cost varies from $5 (for the Raspberry Pi Zero) to $35 (for the Raspberry Pi 3 B and 3 B+). However, if you pick the Zero you will probably also need a USB hub for your mouse and keyboard, possibly a wireless adapter, and some sort of display adapter. Unless you have most (if not all) of the peripherals needed for whatever you want to do with your Raspberry Pi, make sure to add those to your Pi budget. Also, in some countries, a Raspberry Pi on its own (even without any peripherals) may be a cost burden for many students and teachers.
|
||||
|
||||
* **Availability:** Finding the Raspberry Pi you want can vary depending on your location, as it may be easier (or harder) to get certain versions in some countries. Availability is an even bigger issue after new models are released, and it can take a few days or even weeks for new versions to become available in your market.
|
||||
|
||||
* **Purpose:** Location and cost may not affect everyone, but every buyer must consider why they want a Raspberry Pi. The eight different models vary in RAM, CPU core, CPU speed, physical size, network connectivity, peripheral expansion, etc. For example, if you want the most robust solution with more "horsepower," you probably will want the Raspberry Pi 3 B+, which has the most RAM, fastest CPU, and largest number of cores. If you want something that won't require network connectivity, won't be used for CPU-intensive work, and can be hidden in a small space, you could go with a Raspberry Pi Zero.
|
||||
|
||||
|
||||
[Wikipedia's Raspberry Pi specs chart][2] is an easy way to compare the eight Raspberry Pis models.
|
||||
|
||||
Now that you know what to look for in a Raspberry Pi, in the next article, I will explain how to buy one.

How to buy a Raspberry Pi
|
||||
======
|
||||
Find out the best ways to get a Raspberry Pi in the second article in our getting started guide
|
||||
|
||||
|
||||
|
||||
The first article in this series on getting started with Raspberry Pi offered some advice on [which model you should buy][1]. Now that you have an idea of which version you want, let's find out how to get one.
|
||||
|
||||
The most obvious—and probably the safest and simplest—way is through the [official Raspberry Pi website][2]. If you click on "Buy a Raspberry Pi" from the homepage, you'll be taken to the organization's [online store][3], where you can find authorized Raspberry Pi sellers in your country where you can place an order. If your country isn't listed, there is a "Rest of the World" option, which should let you put in an international order.
|
||||
|
||||
Second, check Amazon.com or another major online technology retailer in your country that allows smaller shops to sell new and used items. Given the relatively low cost and size of the Raspberry Pi, it should be fairly easy for smaller shop owners to import and export the boards for reselling purposes. Before you place an order, keep an eye on the sellers' reviews though.
|
||||
|
||||
Third, ask your geek friends! You never know if someone has an unused Raspberry Pi gathering dust. I have given at least three Raspberry Pis away to family, not as planned gifts, but because they were just so curious about this mini-computer. I had so many lying around that I just told them to keep one!
|
||||
|
||||
### Don't forget the extras
|
||||
|
||||
One final thought: don't forget that you'll need some peripherals to set up and operate your Raspberry Pi. At a minimum, you'll need a keyboard, an HDMI cable to connect to a display (and a display), a Micro SD card to install the operating system, a power cord, and a mouse will be handy, too.
|
||||
|
||||
|
||||
|
||||
If you don't already have these items, try borrowing them from friends or order them at the same time you buy your Raspberry Pi. You may want to consider one of the starter kits available from the authorized Raspberry Pi vendors—that will avoid the hassle of searching for parts one at a time.
|
||||
|
||||
|
||||
|
||||
Now that you have a Raspberry Pi, in the next article in this series, we'll install the operating system and start using it.

Learn Linux with the Raspberry Pi
|
||||
======
|
||||
The fourth article in our guide to getting started with the Raspberry Pi dives into the Linux command line.
|
||||
|
||||
|
||||
In the [third article][1] in this series on getting started with Raspberry Pi, I shared info on installing Raspbian, the official version of Linux for Raspberry Pi. Now that you've installed Raspbian and booted up your new Pi, you're ready to start learning about Linux.
|
||||
|
||||
It's impossible to tackle a topic as big as "how to use Linux" in a short article like this, so instead I'll give you some ideas about how you can use the Raspberry Pi to learn more about Linux in general.
|
||||
|
||||
Start by spending time on the command line (aka the "terminal"). Linux [window managers][2] and graphical interfaces have come a long way since the mid-'90s. Nowadays you can use Linux by pointing-and-clicking on things, just as easily as you can in other operating systems. In my opinion, there is a difference between just "using Linux" and being "a Linux user," and the latter means at a minimum being able to navigate in the terminal.
|
||||
|
||||
|
||||
|
||||
If you want to become a Linux user, start by trying out the following on the command line:
|
||||
|
||||
* Navigate your home directory with commands like **ls** , **cd** , and **pwd**.
|
||||
* Create, delete, and rename directories using the **mkdir** , **rm** , **mv** , and **cp** commands.
|
||||
* Create a text file with a command line editor such as Vi, Vim, Emacs, or Nano.
|
||||
* Try out some other useful commands, such as **chmod** , **chown** , **w** , **cat** , **more** , **less** , **tail** , **free** , **df** , **ps** , **uname** , and **kill**
|
||||
* Look around **/bin** and **/usr/bin** for other commands.
|
||||
|
||||
|
||||
|
||||
The best way to get help with a command is by reading its "man page" (short for manual); type **man <command>** on the command line to pull it up. And make sure to search the internet for Linux command cheat sheets—you should find a lot of options that will help you learn.
|
||||
|
||||
Raspbian, like most Linux distributions, has many commands and over time you will end up using some commands a lot more than others. I've been using Linux on the command line for over two decades, and there are still some commands that I've never used, even ones that have been around as long as I've been using Linux.
|
||||
|
||||
At the end of the day, you can use your graphical interface environment to get work done faster, but make sure to dive into the Linux command line, for that's where you will get the true power and knowledge of the operating system.

5 ways to teach kids to program with Raspberry Pi
|
||||
======
|
||||
The fifth article in our guide to getting started with the Raspberry Pi explores resources for helping kids learn to program.
|
||||
|
||||
|
||||
As countless schools, libraries, and families have proven, the Raspberry Pi is a great way to expose kids to programming. In the first four articles in this series, you've learned about [purchasing][1], [installing][2], and [configuring][3] a Raspberry Pi. In this fifth article, I'll share some helpful resources to get kids started programming with the Raspberry Pi.
|
||||
|
||||
### Scratch
|
||||
|
||||
[Scratch][4] is a great way to introduce kids to basic programming concepts like variables, boolean logic, loops, and more. It's included in Raspbian, and you can find numerous articles and tutorials about Scratch on the internet, including [Is Scratch today like the Logo of the '80s for teaching kids to code?][5] on Opensource.com.
|
||||
|
||||
|
||||
|
||||
### Code.org
|
||||
|
||||
[Code.org][6] is another great online resource for kids learning to program. The organization's mission is to expose more people to coding through courses, tutorials, and the popular Hour of Code event. Many schools—including my fifth-grade son's—use it to expose more kids to programming and computer science concepts.
|
||||
|
||||
### Reading
|
||||
|
||||
Reading books is another great way to learn how to program. You don't necessarily need to speak English to learn how to program, but the more you know, the easier it will be, as most programming languages use English keywords to describe the commands. If your English is good enough to follow this Raspberry Pi series, you are most likely well-equipped to read books, forums, and other publications about programming. One book I recommend is [Python for Kids: A Playful Introduction to Programming][7] by Jason Biggs.
|
||||
|
||||
### Raspberry Jam
|
||||
|
||||
Another way to get your kids into programming is by helping them interact with others at meetups. The Raspberry Pi Foundation sponsors events called [Raspberry Jams][8] around the world where kids and adults can join forces and learn together on the Raspberry Pi. If there isn't a Raspberry Jam in your area, the foundation has a [guidebook][9] and other resources to help you start one.
|
||||
|
||||
### Gaming
|
||||
|
||||
Last, but not least, there's a version of [Minecraft][10] for the Raspberry Pi. Minecraft has grown from a multi-player "digital Lego"-like game into a programming platform where anyone can use Python and other languages to build on Minecraft's virtual world. Check out [Getting Started with Minecraft Pi][11] and [Minecraft Hour of Code Tutorials][12].

你应该选择哪种树莓派？
|
||||
======
|
||||
在我们的《树莓派使用入门》系列的第一篇文章中，我们将学习选择符合你要求的树莓派型号的三个标准。
|
||||
|
||||
|
||||
本文是《14 天学会[树莓派][1]使用》系列文章的第一篇。虽然本系列文章主要面向没有使用过树莓派或 Linux 或没有编程经验的人群，但是肯定有些东西还是需要有经验的读者的，我希望这些读者能够留下他们有益的评论、提示和补充。如果每个人都能贡献，这将会让本系列文章对初学者、其它有经验的读者、甚至是我更受益！
|
||||
|
||||
言归正传，如果你想拥有一个树莓派，但不知道应该买哪个型号。或许你希望为你的教学活动或你的孩子买一个，但面对这么多的选择，却不知道应该买哪个才是正确的决定。
|
||||
|
||||
|
||||
|
||||
关于选择一个新的树莓派，我有三个主要的标准：
|
||||
|
||||
* **成本：** 不能只考虑树莓派板的成本，还需要考虑到你使用它时外围附件的成本。在美国，树莓派的成本区间是从 5 美元（树莓派 Zero）到 35 美元（树莓派 3 B 和 3 B+）。但是，如果你选择 `Zero`，那么你或许还需要一个 `USB hub` 去连接你的鼠标、键盘、无线网卡、以及某种显示适配器。不论你想使用树莓派做什么，除非你已经有了（假如不是全部）大部分的外设，那么你一定要把这些外设考虑到预算之中。此外，在一些国家，对于许多学生和老师，树莓派（即便没有任何外设）的购置成本也或许是一个不少的成本负担。
|
||||
|
||||
* **可获得性：** 根据你所在地去查找你想要的树莓派，因为在一些国家得到某些版本的树莓派可能很容易（或很困难）。在新型号刚发布后，可获得性可能是个很大的问题，在你的市场上获得最新版本的树莓派可能需要几天或几周的时间。
|
||||
|
||||
* **用途：** 所在地和成本可能并不会影响每个人，但每个购买者必须要考虑的是买树莓派做什么。因内存、CPU 核心、CPU 速度、物理尺寸、网络连接、外设扩展等不同衍生出八个不同的型号。比如，如果你需要一个拥有更大的“马力”时鲁棒性更好的解决方案，那么你或许应该选择树莓派 3 B+，它有更大的内存、最快的 CPU、以及更多的核心数。如果你的解决方案并不需要网络连接，并不用于 CPU 密集型的工作，并且需要将它隐藏在一个非常小的空间中，那么一个树莓派 Zero 将是你的最佳选择。
|
||||
|
||||
[维基百科的树莓派规格表][2] 是比较八种树莓派型号的好办法。
|
||||
|
||||
现在，你已经知道了如何找到适合你的树莓派了，下一篇文章中，我将介绍如何购买它。

如何购买一个树莓派
|
||||
======
|
||||
在我们的《树莓派入门指南》系列文章的第二篇中，我们将介绍获取树莓派的最佳途径。
|
||||
|
||||
|
||||
|
||||
在本系列指南的第一篇文章中，我们提供了一个关于 [你应该购买哪个版本的树莓派][1] 的一些建议。哪个版本才是你想要的，你应该有了主意了，现在，我们来看一下如何获得它。
|
||||
|
||||
最显而易见的方式— 并且也或许是最安全最简单的方式 —非[树莓派的官方网站][2] 莫属了。如果你从官网主页上点击“Buy a Raspberry Pi”，它将跳转到官方的 [在线商店][3]，在那里，它可以给你提供你的国家所在地的授权销售商。如果你的国家没有在清单中，还有一个“其它”选项，它可以提供国际订购。
|
||||
|
||||
第二，查看亚马逊或在你的国家里允许销售新的或二手商品的其它主流技术类零售商。鉴于树莓派比较便宜并且尺寸很小，一些小商家基于转售目的的进出口它，应该是非常容易的。在你下订单时，一定要关注对卖家的评价。
|
||||
|
||||
第三，打听你的极客朋友！你可能从没想过一些人的树莓派正在“吃灰”。我已经给家人送了至少三个树莓派，当然它们并不是计划要送的礼物，只是因为他们对这个“迷你计算机”感到很好奇而已。我身边有好多个，因此我让他们拿走一个！
|
||||
|
||||
### 不要忘了外设
|
||||
|
||||
最后一个建设是：不要忘了外设，你将需要一些外设去配置和操作你的树莓派。至少你会用到键盘、一个 HDMI 线缆去连接显示器、一个 Micro SD 卡去安装操作系统，一个供电线、以及一个好用的鼠标。
|
||||
|
||||
|
||||
|
||||
如果你没有准备好这些东西，试着从朋友那儿借用，或与树莓派一起购买。你可以从授权的树莓派销售商那儿考虑订购一个起步套装 — 它可以让你避免查找的麻烦而一次性搞定。
|
||||
|
||||
|
||||
|
||||
现在，你有了树莓派，在本系列的下一篇文章中，我们将安装树莓派的操作系统并开始使用它。

用树莓派学 Linux
|
||||
======
|
||||
我们的《树莓派使用入门》的第四篇文章将进入到 Linux 命令行。
|
||||
|
||||
|
||||
在本系列的 [第三篇文章][1] 中开始了我们的树莓派探索之旅，我分享了如何安装 `Raspbian`，它是树莓派的官方 Linux 版本。现在，你已经安装好了 `Raspbian` 并用它引导你的新树莓派，你已经具备学习 Linux 相关知识的条件了。
|
||||
|
||||
在这样简短的文章中去解决像“如何使用 Linux” 这样的宏大主题显然是不切实际的，因此，我只是给你提供一些如何使用树莓派来学习更多的 Linux 知识的一些创意而已。
|
||||
|
||||
我们花一些时间从命令行（又称“终端”）开始。自上世纪九十年代中期以来，Linux 的 [窗口管理器][2] 和图形界面已经得到长足的发展。如今，你可以在 Linux 上通过鼠标点击来做一些事情了，就如同其它的操作系统一样容易。在我看来，只是“使用 Linux”和成为“一个 Linux 用户”是有区别的，后者至少能够在终端中“遨游“。
|
||||
|
||||
|
||||
|
||||
如果你想成为一个 Linux 用户，从终端中尝试以下的命令行开始：
|
||||
|
||||
* 使用像 **ls**、**cd**、和 **pwd** 这样的命令导航到你的 Home 目录。
|
||||
* 使用 **mkdir**、**rm**、**mv**、和 **cp** 命令创建、删除、和重命名目录。
|
||||
* 使用命令行编辑器（如 Vi、Vim、Emacs 或 Nano）去创建一个文本文件。
|
||||
* 尝试一些其它命令，比如 **chmod**、**chown**、**w**、**cat**、**more**、**less**、**tail**、**free**、**df**、**ps**、**uname**、和 **kill**。
|
||||
* 尝试一下 **/bin** 和 **/usr/bin** 目录中的其它命令。
|
||||
|
||||
|
||||
|
||||
学习命令行的最佳方式还是阅读它的 “man 手册”（简称手册）；在命令行中输入 **man <command>** 就可以像上面那样打开它。并且在互联网上搜索 Linux 命令速查表可以让你更清楚地了解命令的用法 — 你应该会找到一大堆能帮你学习的资料。
|
||||
|
||||
Raspbian 就像主流的 Linux 发行版一样有非常多的命令，假以时日，你最终将比其他人会用更多的命令。我使用 Linux 命令行已经超过二十年了，即便这样仍然有些一些命令我从来没有使用过，即便是那些我使用的过程中一直就存在的命令。
|
||||
|
||||
最后，你可以使用图形环境去更快地工作，但是只有深入到 Linux 命令行，你才能够获得操作系统真正的强大功能和知识。

教孩子们使用树莓派学编程的 5 种方法。
|
||||
======
|
||||
这是我们的《树莓派入门指南》系列的第五篇文章，它探索了帮助孩子们学习编程的一些资源。
|
||||
|
||||
|
||||
无数的学校、图书馆和家庭已经证明，树莓派是让孩子们接触编程的最好方式。在本系列的前四篇文章中，你已经学习了如何去[购买][1]、[安装][2]、和[配置][3]一个树莓派。在第五篇文章中，我们将分享一些帮助孩子们使用树莓派编程的入门级资源。
|
||||
|
||||
### Scratch
|
||||
|
||||
[Scratch][4] 是让孩子们了解编程基本概念（比如变量、布尔逻辑、循环等等）的一个很好的方式。你在 Raspbian 中就可以找到它，并且在互联网上你可以找到非常多的有关 Scratch 的文章和教程，包括在 `Opensource.com` 上的 [今天的 Scratch 是不是像“上世纪八十年代教孩子学LOGO编程”?][5]。
|
||||
|
||||
|
||||
|
||||
### Code.org
|
||||
|
||||
[Code.org][6] 是另一个非常好的教孩子学编程的在线资源。这个组织的使命是让更多的人通过课程、教程和流行的一小时学编程来接触编程。许多学校 — 包括我五年级的儿子就读的学校 — 都使用它，让更多的孩子学习编程和计算机科学的概念。
|
||||
|
||||
### 阅读
|
||||
|
||||
读书是学习编程的另一个很好的方式。学习如何编程并不需要你会说英语，当然，如果你会英语的话，学习起来将更容易，因为大多数的编程语言都是使用英文关键字去描述命令的。如果你的英语很好，能够轻松地阅读接下来的这个树莓派系列文章，那么你就完全有能力去阅读有关编程的书籍、论坛和其它的出版物。我推荐一本由 `Jason Biggs` 写的书： [儿童学 Python：非常有趣的 Python 编程入门][7]。
|
||||
|
||||
### Raspberry Jam
|
||||
|
||||
另一个让你的孩子进入编程世界的好方法是在聚会中让他与其他人互动。树莓派基金会赞助了一个称为 [Raspberry Jams][8] 的活动，让世界各地的孩子和成人共同参与在树莓派上学习。如果你所在的地区没有 `Raspberry Jam`，基金会有一个[指南][9]和其它资源帮你启动一个 `Raspberry Jam`。
|
||||
|
||||
### 游戏
|
||||
|
||||
最后一个（是本文的最后一个，当然还有其它的方式），[Minecraft][10] 有一个树莓派版本。<ruby>我的世界<rt>Minecraft</rt></ruby>已经从一个多玩家的、类似于”数字乐高“这样的游戏，成长为一个任何人都能使用 Pythonb 和其它编程语言去构建我自己的虚拟世界。更多内容查看 [Minecraft Pi 入门][11] 和 [Minecraft 一小时入门教程][12]。
