Ansible streaming video series, open source security tools, and more industry trends
|
||||
======
|
||||
A weekly look at open source community and industry trends.
|
||||
![Person standing in front of a giant computer screen with numbers, data][1]
|
||||
|
||||
As part of my role as a senior product marketing manager at an enterprise software company with an open source development model, I publish a regular update about open source community, market, and industry trends for product marketers, managers, and other influencers. Here are five of my and their favorite articles from that update.
|
||||
|
||||
## [Ansible 101 by Jeff Geerling: a YouTube streaming series][2]
|
||||
|
||||
> After the incredible response I got from [making my Ansible books free for the rest of March][3] to help people learn new automation skills, I tried to think of some other things I could do to help developers who may be experiencing hardship during the coronavirus pandemic and market upheaval.
|
||||
|
||||
**The impact**: Not everyone is a frontline worker in this crisis, but then not every problem it has created needs one. This is a great example of someone using their resources to help in a unique way.
|
||||
|
||||
## [Open source security tools for cloud and container applications][4]
|
||||
|
||||
> Open-source security tools play an important role in securing your container-based infrastructure. Tools such as Anchore can be used for strong governance capabilities, while on the other hand, Dagda can be used to perform static analysis of known vulnerabilities. Two other tools, OpenSCAP and Clair, also provide good capabilities for vulnerability scanning and compliance management. So, depending upon your business requirements and priorities, you can select the right tool to secure your container investments.
|
||||
|
||||
**The impact**: Containers are Linux, and container security is open source as well.
|
||||
|
||||
## [Cloud cover: Clearing up some misunderstandings about data centres][5]
|
||||
|
||||
> The [carbon footprint of data][6] is becoming more and more of a concern, but there appears to be little economic interest in decreasing the amount of data flowing around the world to mitigate this. In that scenario, finding the most energy-efficient and carbon-neutral ways to run purpose-built data centres could be the only answer.
|
||||
|
||||
**The impact**: I was talking to a colleague who manages a team of virtualization engineers about this very problem. He seemed optimistic about the amount of headway his team could make on improving the energy consumption of things like KVM at the kernel level; though at the moment customers aren't asking for it. I'd guess that if, for example, the price of carbon emissions were to go up for some reason, that situation would change pretty quickly.
|
||||
|
||||
## [Business culture is key in OpenStack network requirements][7]
|
||||
|
||||
> The main question is: What is your [culture][8]? Do you go to a vendor and say, 'Give me your design, tell me what to buy and how to support it'? Starting out, you evaluate systems. What are your options?
|
||||
>
|
||||
> If you have siloed folks that work on a particular model of equipment, then OpenStack is probably not for you. If you have people that function at a higher level with some fundamental understanding about the underlying architecture that makes things work, then OpenStack can be very useful for you, and you're much less restricted.
|
||||
|
||||
**The impact:** Not every organization can adopt a given technology. Certainly not without a willingness to change at a fundamental level.
|
||||
|
||||
_I hope you enjoyed this list and come back next week for more open source community, market, and industry trends._

IBM taps new leaders for hybrid cloud battles ahead
|
||||
======
|
||||
IBM installs Arvind Krishna as CEO, and appoints Red Hat execs to round out new cloud-oriented team
|
||||
Stephen Lawson/IDG
|
||||
|
||||
Amid the business chaos COVID-19 is causing, IBM has set its course by [installing][1] Arvind Krishna as CEO and Red Hat CEO Jim Whitehurst as IBM president. The company also named Red Hat veteran Paul Cormier as CEO of Red Hat.
|
||||
|
||||
Krishna replaces long-time CEO Virginia Rometty, who will retire at the end of the year, and the package of executive moves solidifies the team that will lead Big Blue into to [hybrid-cloud][2] world where it will battle Amazon, Google and Microsoft.
|
||||
|
||||
[[Get regularly scheduled insights by signing up for Network World newsletters.]][3]
|
||||
|
||||
Right now, though, that team must also compete in the face the COVID-19 pandemic, an issue [Krishna][4] mentioned in a [letter he posted on LinkedIn][5] on his first day on the job, April 6.
|
||||
|
||||
“During this challenging time, we all need to have empathy, solidarity, and understanding for each other…If there’s one thing that this public health crisis has brought to light it is the ever essential role of IBM in the world. We are the backbone of some of the most critical systems of the world. Our technologies and services help banks run credit-card transactions, businesses run supply chains, telcos connect customers, healthcare providers improve patient care, and companies and cities tackle cyberthreats,” Krishna wrote.
|
||||
|
||||
IBM has been part of the technology community that is helping address COVID-19. For example, [IBM Research][6] has been developing cloud and AI-powered technologies that can help researchers battle against coronavirus, in part by accelerating COVID-19 drug discovery.
|
||||
|
||||
IBM is also leading the [COVID-19 High Performance Computing Consortium][7] with AWS, Google, HPE, and Microsoft as well as US National Labs, NASA, and others to bring [high-performance computing][8] systems together to help researchers run massive modeling calculations.
|
||||
|
||||
While COVID-19 is a focus for now, the long term-goal is developing cloud technologies.
|
||||
|
||||
[][9]
|
||||
|
||||
“I believe we can make IBM the most trusted technology partner of the 21st century. For this to happen, we have to ensure that IBM continues to innovate and lead in the transformational journeys our clients are on. Hybrid cloud and AI are two dominant forces driving change for our clients and must have the maniacal focus of the entire company,” he stated.
|
||||
|
||||
### Linux, Kubernetes and containers
|
||||
|
||||
Krishna also wrote about IBM’s strategic cloud directions going forward. “First, we have to deepen our understanding of IBM’s two strategic battles: the journey to hybrid cloud and AI. We all need to understand and leverage IBM’s sources of competitive advantage. Namely, our open source and security leadership, our deep expertise and trust, and the fact that we enable clients to build mission-critical applications once and run them anywhere,” Krishna stated.
|
||||
|
||||
IBM also has to win the battle for architecting the cloud. “There’s a unique window of opportunity for IBM and Red Hat to establish [Linux][10], containers and Kubernetes as the new standard. We can make Red Hat OpenShift the default choice for hybrid cloud in the same way that Red Hat Enterprise Linux is the default choice for the operating system,” Krishna stated.
|
||||
|
||||
When IBM closed its [acquisition][11] of Red Hat last July for $34 billion it was clear it would take on the hybrid-cloud market and now, especially with the current executive team in place, that path is set more solidly.
|
||||
|
||||
Krishna, 57, was a principal architect of IBM’s $34 billion acquisition of Red Hat last year and was IBM’s senior vice president of Cloud and Cognitive Software. Red Hat said Cormier drove more than 25 acquisitions at Red Hat and is credited with pioneering the subscription model that transformed Red Hat from an open-source disruptor to an enterprise-technology mainstay.
|
||||
|
||||
Also as part of the new team, IBM said it tapped Bank of America telecom and cloud-technology executive Howard Boville as senior vice president of cloud platform, overseeing the IBM Cloud.

New Linux integrity checker from Microsoft, Raspberry Pi smart TV replacement from KDE, and more open source news
|
||||
======
|
||||
Catch up on the biggest open source headlines from the past two weeks.
|
||||
![][1]
|
||||
|
||||
In this edition of our open source news roundup, we take a look at GNOME Foundation's new contributor program, a new Linux integrity checker from Microsoft, a free software alternative to smart TVs, and more!
|
||||
|
||||
### GNOME Foundation launches a new contributor program
|
||||
|
||||
A key part of keeping open source communities vibrant and healthy is bringing in new contributors. To help promote this, the GNOME Foundation and Endless teamed up to launch the inaugural [Community Engagement Challenge][2]. Phase one launched this week by opening the call for submitting project applications. Candidate projects should be aimed at bringing beginners into open source and encouraging ongoing participation in open source communities. Projects don’t have to be coding, they can also be games, videos, written materials, and so on.
|
||||
|
||||
A panel of judges will select 20 projects to participate in phase two, where ideas will be turned into proofs of concept. At each phase, cash prizes will be awarded. [Proposals][3] are due July 1, 2020.
|
||||
|
||||
### Microsoft announces code integrity checker for Linux
|
||||
|
||||
When you run a program, you want it to be the one you think you’re running. This week, Microsoft announced [Integrity Policy Enforcement][4] (IPE), a Linux Security Model released under the GPLv2.
|
||||
|
||||
IPE is targeted toward specific-purpose devices like network firewalls, not for general-purpose computing. It provides runtime verification that the code being executed matches the desired version. This allows administrators to detect and block altered binaries.
|
||||
|
||||
IPE is currently in the Request for Comments stage on the [linux-security-module][5] mailing list.
|
||||
|
||||
### KDE announces Plasma Bigscreen
|
||||
|
||||
I recently bought a new TV and, if you haven’t been in the market lately, it’s hard to find “dumb” televisions. I didn’t want a smart TV because I worry about the manufacturer abandoning the software and what the device might do with my data. So KDE’s recent [Plasma Bigscreen][6] announcement caught my eye.
|
||||
|
||||
Plasma Bigscreen takes the KDE Plasma interface I use every day and combines it with [Mycroft AI][7] to turn single-board computers into a smart TV. The beta, released last month, includes support for the Raspberry Pi 4 (Model B).

Meet LBRY, A Blockchain-based Decentralized Alternative to YouTube
|
||||
======
|
||||
|
||||
_**LBRY is a new Blockchain-based, open source platform for sharing digital content. It is gaining popularity as a decentralized alternative to YouTube but LBRY is more than just a video sharing service.**_
|
||||
|
||||
### LBRY is an open source blockchain based platform for content sharing
|
||||
|
||||
At the core of it, [LBRY][1] is a new protocol which is a peer to peer, decentralized file sharing and payment network secured by [blockchain][2] technology. Anyone can build apps on top of LBRY protocol that interact with digital content on the LBRY network. But these technical stuff is for developers.
|
||||
|
||||
As a user you can use [LBRY platform][3] for watching videos, listening to music and reading eBooks.
|
||||
|
||||
As a content creator, you can use LBRY to share your digital content like video, music, images, podcasts, eBooks etc.
|
||||
|
||||
Unlike YouTube, your activities are not tracked to serve you ads. In fact, LBRY is ad free. If you are logged into the network, you won’t see any ads anywhere on its website.
|
||||
|
||||
### No ads, and you may even earn cryptocurrency for viewing videos on LBRY
|
||||
|
||||
The LBRY is ‘governed’ by its own cryptocurrency called LBC (LBRY Credits).
|
||||
|
||||
Like any other cryptocurrency, you can mine it, buy it or get it from someone else. Content creators can set a price in LBC for streaming their content or they can provide it for free and get tipped in LBC by the viewers.
|
||||
|
||||
Don’t worry, you don’t necessarily need to buy LBC. Since its new, you’ll get LBC as rewards for doing simple tasks as viewing videos, exploring LBRY, following channels etc. In fact, you’ll get a few LBC simply for creating an account at LBRY and setting up your profile.
|
||||
|
||||
![LBRY Rewards Sample][4]
|
||||
|
||||
You’ll also get LBC in rewards for inviting other users to LBRY platform. For example, if you join [LBRY from It’s FOSS invite link][5], both you and I get LBC as reward.
|
||||
|
||||
The LBRY reward system will change once the platform grows. Remember initially Bitcoins were also readily available and now it values thousands of dollars.
|
||||
|
||||
### Open source, peer to peer, blockchain: LBRY ticks all the right blocks for a privacy-aware user
|
||||
|
||||
![LBRY interface][6]
|
||||
|
||||
While the cyptocurrency is essential to create a fair and open marketplace in LBRY, its main feature is the peer to peer, decentralized network using blockchain. LBRY puts emphasis on treating you as user, not a product.
|
||||
|
||||
Everything built to power LBRY is open source. You can find the entire source code on its GitHub repository.
|
||||
|
||||
[LBRY on GitHub][7]
|
||||
|
||||
The [LBRY FAQ page][8] is a good resource to know more about LBRY and how it works.
|
||||
|
||||
### Using LBRY
|
||||
|
||||
![][9]
|
||||
|
||||
If you want to give LBRY a try, you can check out its [video sharing platform][3]. If you are logged in or using its app, you won’t see any ads.
|
||||
|
||||
Creating an account on LBRY will also let you get the LBRY rewards (i.e. the LBC cryptocurrency). You can watch the videos on LBRY web site or on its application.
|
||||
|
||||
I have noticed that video streaming is slightly faster when you use the app instead of web browser. [LBRY app is available][10] for Linux, Windows, macOS, iOS and Android.
|
||||
|
||||
As a web publisher, It’s FOSS is on all major social media channels. We appreciate and respect such decentralized services and try to make a presence on such offbeat platform. You can [find us on Mastodon][11], a [decentralized alternative to Twitter][12]. You can also find It’s FOSS on LBRY.
|
||||
|
||||
While we will be putting our video content primarily on YouTube and Vimeo (for ad-free experience), our YouTube content will be automatically available on LBRY as well.
|
||||
|
||||
So if you are going to use LBRY, you can follow us there to watch all our videos on LBRY.
|
||||
|
||||
[Join LBRY and follow It’s FOSS][5]
|
||||
|
||||
### Conclusion
|
||||
|
||||
There may not be a lot of content on LBRY right now. LBRY is trying to encourage and reward creators who publish on LBRY first instead of YouTube.
|
||||
|
||||
LBRY is in early stages but its team is working hard to become a viable alternative to YouTube. It has an open road map where they have shared an insight into all their future plans. You may [check it out yourself][13].
|
||||
|
||||
By the way, LBRY is not the only platform of this kind. [PeerTube][14] is a similar service that provides a peer to peer video sharing platform.
|
||||
|
||||
_**If you are someone who doesn’t like tech giants like Google, Microsoft, Huawei ‘spying’ on your data, keeping a profile of you to serve you targeted ads, you may try platforms like PeerTube and LBRY.**_
|
||||
|
||||
What do you think of LBRY? Are you already using something like LBRY or PeerTube? If not, are you willing to give it a try? What’s your overall feeling about P2P platforms like LBRY? Do share your views in the comment section.

A handy utility for creating Raspberry Pi SD card images
|
||||
======
|
||||
Getting started with Raspberry Pi Imager on a Mac.
|
||||
![Raspberries with pi symbol overlay][1]
|
||||
|
||||
There are many ways to buy a Raspberry Pi, and depending on who you buy it from, it may or may not come with an operating system already installed on it. Getting an OS onto a Raspberry Pi is a matter of "flashing" an SD card with an OS image. To make this as easy as possible, the [Raspberry Pi Foundation][2] has introduced a Raspberry Pi Imager application, and you can download it for all major platforms. Here's a quick intro to this helpful new utility.
|
||||
|
||||
### Install the Imager
|
||||
|
||||
You can find the Raspberry Pi Imager over at the usual [Raspberry Pi Downloads][3] page. Versions exist for Mac, Ubuntu, and Windows. I will download and demonstrate the Mac version.
|
||||
|
||||
Installation on Mac consists of the usual DMG image that mounts to your desktop, and then a typical installer window appears:
|
||||
|
||||
![Raspberry Pi Imager installer][4]
|
||||
|
||||
Simply drag the cute raspberry icon to the Application folder, and you are done. Invoke that from Launchpad, and you are presented with a series of simple buttons and menus to choose from. It really cannot be simpler than this:
|
||||
|
||||
![Raspberry Pi Imager home screen][5]
|
||||
|
||||
### Images and options available
|
||||
|
||||
The default options contain a variety of images for various Raspberry Pi models. Raspbian is the top choice with two available options for smaller "Lite" and fatter "Full" versions available. The LibreELEC Kodi entertainment system is available in various model-specific builds. Ubuntu 18 and 19 have 32-bit and 64-bit builds available for different Pi models. There is an RPi 4 EEPROM recovery utility and a function to format your card using FAT32. Finally, a generic image installer option is available that I will try out a little later. Pretty handy for a simple and compact utility.
|
||||
|
||||
### Install some images
|
||||
|
||||
I had a 16g micro SD card that I decided to play with. I selected the default Raspbian image, chose my attached USB/SD device, and pressed WRITE. Here is a brief demo:
|
||||
|
||||
![Raspberry Pi Imager demo][6]
|
||||
|
||||
I didn't post the entire sequence there. I believe it downloaded the image as it was writing and took a few minutes on my wireless connection to finish. The process goes through a write and then a verify cycle before it is finished. When it was done, I ejected the device, popped the card into my RPi 3, and was treated to the usual graphical Raspbian setup wizard and desktop environment.
|
||||
|
||||
That wasn't quite enough for me; I get plenty of Linux on a daily basis and was looking for a little more today. I went back to the [Raspberry Pi Downloads][3] page and pulled down the RISC OS image. This process was nearly as easy. Download the RISCOSPi.5.24.zip file, extract it, and find the ro524-1875M.img file. From the Operating System button, I selected the Use Custom option and selected the desired image file. The process was pretty much the same; the only real difference being I had to hunt around my Downloads directory and select an image. Once the file was finished writing, back into the Pi 3, and RISC OS was ready to go.
|
||||
|
||||
### Gripes on USB C
|
||||
|
||||
This is just a silly aside, but how many of you are a bit frustrated with the total inconvenience of USB C these days? I'm using a MacBook Pro, which only has USB C ports, and I am subject to a never-ending swap of adapters to get things done. Take a look at this:
|
||||
|
||||
![USB C adapter][7]
|
||||
|
||||
Yes, that is a USB C to USB A adapter, then a USB to SD card reader, and an SD to micro SD adapter inside. I probably could have found something online to simplify this, but these are the parts I had on hand to support my family's myriad Mac, Windows, and Linux hosts. Enough about that, but I hope you got a chuckle from that insanity.
|
||||
|
||||
### Summary
|
||||
|
||||
The new Raspberry Pi Imager is a simple and effective tool for getting off the ground quickly with Raspberry Pi images. [BalenaEtcher][8] is a similar tool for imaging your removable devices, but this new Raspberry Pi Imager makes the process of common RPi OS installations (like Raspbian) a bit easier by eliminating the steps to fetch those common images.

A stress-free guide to keeping WordPress sites updated
|
||||
======
|
||||
This practical guide to a necessary task will show you how to maximize
|
||||
site performance and avoid bugs and other issues with regular updates.
|
||||
![Working from home at a laptop][1]
|
||||
|
||||
We all know how important it is to keep WordPress sites updated. New updates provide the latest bug and security fixes against any nasties lurking on the web. But, more critically, an outdated site can also lead to poor performance, such as slow loading speed or an outdated look and feel.
|
||||
|
||||
Unfortunately, keeping your WordPress site up-to-date is not as easy as clicking a button. There are several components to consider, from theme to plugins to PHP. Even worse, updating too quickly can wreak another kind of havoc. Have you ever experienced the dreaded, "There has been a critical error on your website" warning after an innocent little update? I know I have, many times!
|
||||
|
||||
Here is a practical guide on what to look out for, as well as when and what to update, to ensure your WordPress site works well.
|
||||
|
||||
### Updating WordPress
|
||||
|
||||
Let's start with the basics. Check your WordPress version is up-to-date by visiting Dashboard > Updates.
|
||||
|
||||
![WordPress update screen][2]
|
||||
|
||||
### Choosing a WordPress theme
|
||||
|
||||
Before we deep dive into updating themes, I'd like to take a few steps back. Choose an up-to-date theme from the get-go and do your homework before installing it! There is nothing worse than pouring your heart and soul into customizing a new theme, only to discover it is buggy.
|
||||
|
||||
Questions to ask when choosing a theme include:
|
||||
|
||||
* When was it first created?
|
||||
* What is the current version available?
|
||||
* Does the theme provider still maintain an active demo site and helpdesk?
|
||||
* What do recent reviews say about the theme?
|
||||
|
||||
|
||||
|
||||
If the theme provider is no longer maintaining the theme, save yourself the trouble and move on. Also, don't assume that just because you paid for a theme, that is necessarily maintained. I recently fell into this trap when I purchased [Pinable][3]. I loved the Pinterest look and feel. However, soon after installation, I noticed the lack of customization within the theme settings, major compatibility issues arose with my plugins, and the customer service was nonexistent. I should have known better. The theme was created in 2013 and selling for a bargain.
|
||||
|
||||
If you already have a theme, then pay attention to how frequently updates become available. If there are never any updates, the theme provider may have closed up shop. It is only a matter of time before the impact of an outdated theme will cause problems.
|
||||
|
||||
A quick aside while we are on the topic—up-to-date themes also give access to the two new alignment options in the WordPress block editor, which enable wide-width and full-width images. These help your blog posts look more professional. While there are a number of [tutorials][4] on the web that show you how to manually update your functions, PHP file, and CSS to enable the new alignment blocks, the code does not always work on older themes (especially masonry themes).
|
||||
|
||||
![Wordpress theme][5]
|
||||
|
||||
### Updating themes
|
||||
|
||||
To check the current version of your theme, go to Appearance > Themes and click on the active theme to see the current version. If an upgrade is available, there will be an alert banner. Click on "update now" to initiate the update. You can also check for updates by going to Dashboard > Updates.
|
||||
|
||||
![Themify screenshot][6]
|
||||
|
||||
If you purchased a theme from a marketplace such as [Envato][7] or [Themify][8], check the theme documentation to learn what is required to initiate updates, as it will not show up automatically in the dashboard. In most cases, you will be required to download and install a specific plugin or manually upload new versions when they become available. In the latter case, you will need to delete or rename the old theme file via your cPanel before you can install the new one. A guide to installing themes via cPanel is available [here][9].
|
||||
|
||||
If you plan to customize your theme extensively and are worried about the impact of this when upgrading, consider creating a child theme first. A child theme lets you make changes without touching the original theme's code. You can then update your site without losing any customizations you've made. Read more about child themes [here][10].
|
||||
|
||||
As I said before, the source of most issues tends to be the theme. Learn what is required to keep your theme up to date, and do so regularly. If your theme provider is no longer creating updates, then find a new theme.
|
||||
|
||||
### Easy does it for plugins
|
||||
|
||||
If you manage multiple plugins, then you will be used to the frequent dashboard reminders to update! Before we get onto that, though, let's touch on some basics.
|
||||
|
||||
As a general rule, you don't want to have too many plugins. They slow down the speed of your site by creating more code that the browser has to load. Always delete any inactive plugins. I prefer to manage plugins on the Plugins tab. Here you can see all active and inactive plugins, the current version, and whether an update is available. To update the plugin, simply click "update."
|
||||
|
||||
![Plugin update page][11]
|
||||
|
||||
Nonetheless, I implore you to wait a week or two before installing new updates. Updating my plugins too quickly has caused me no end of grievances. To begin with, updates are prone to human error. Don't be the guinea pig that tests out the latest version. Sometimes, the newest version of a plugin is not compatible with an older version of WordPress or your theme. Check these are up-to-date first.
|
||||
|
||||
### Website down after updating plugins?
|
||||
|
||||
If your site has stopped working or performance has dropped noticeably after updating your plugins, then all is not lost. Forget about those newfangled plugins that promise to test speed and identify buggy plugins (the last thing you want is more plugins)! Disable all your plugins, then activate one at a time while you test the speed and performance of your site on a website such as [Pingdom][12]. This is a great exercise to perform periodically, even if your website has not crashed. Once you identify the plugin causing the problem, delete it.
|
||||
|
||||
In the event you cannot access WordPress because there is a critical error, then you will need to access your files via cPanel and delete all the plugin folders from there ([full instructions here][13]). Don't worry; doing this will not impact your website's content. You can then proceed to reinstall and activate the plugins one-by-one via WordPress.
|
||||
|
||||
Cache plugins tend to be the biggest culprit in my experience. Issues with cache plugins can be minimized by clearing the cache frequently. Do not install multiple cache plugins that perform the same function, as they will only serve to slow down your site. The only way to truly get around cache plugin issues is to either not use them, use a plugin recommended by your hosting provider, or become an expert on cache. [This blog][14] on common cache issues in WordPress is a good place to start.
|
||||
|
||||
### Back up before updating PHP
|
||||
|
||||
If you are concerned about your website speed and have spent enough time browsing Google for answers, then you likely have seen the advice, "You gotta update your PHP!" Please tread carefully with manual PHP updates, though! If you have a good hosting provider, you should never need to do this. Rather, select the option for automatic PHP version management with your host. Newer versions of PHP may not be stable or compatible with the version of WordPress you are running. Let your hosting provider be the one to determine when updates are ready.
|
||||
|
||||
However, if you are adamant that an old version of PHP is causing your website to be slow, take care to follow these steps before initiating an update. First, back up your site. Investing in a premium version of [Jetpack][15] is worth its weight in gold. Jetpack can perform real-time as well as daily backups, depending on your plan. Not to mention, their customer service and troubleshooting support are excellent. Secondly, inform your hosting provider that you plan to update the PHP and seek their advice first. If your host is unable to advise or wants to charge you for the privilege, you should probably think about changing hosts.
|
||||
|
||||
You can update PHP either via cPanel or via your hosting platform under Devs > PHP Manager. After that, you are on your own, as that is where my expertise on PHP ends.

一个方便的用于创建树莓派 SD 卡镜像的程序
|
||||
======
|
||||
开始在 Mac 上使用 Raspberry Pi Imager
|
||||
![Raspberries with pi symbol overlay][1]
|
||||
|
||||
有多种购买树莓派的方法，同时树莓派会取决于你从哪里购买的从而可能附带或不附带操作系统。将操作系统安装到树莓派上就是用系统镜像“刷新” SD 卡。为了使之尽可能简单，[树莓派基金会][2]引入了 Raspberry Pi Imager，你可以将其下载到所有主流平台。以下这个有用的新工具介绍。
|
||||
|
||||
### 安装 Imager
|
||||
|
||||
你通常可以在[树莓派下载][3]页面上找到 Raspberry Pi Imager。它有 Mac、Ubuntu 和 Windows 版本。我将下载并演示 Mac 版本。
|
||||
|
||||
Mac 的安装包是常规的 DMG 镜像，它会挂载到你的桌面，然后经典的安装界面就会出现：
|
||||
|
||||
![Raspberry Pi Imager installer][4]
|
||||
|
||||
只需将可爱的树莓图标拖到 Application 文件夹，就可以完成。从 Launchpad 中调用它，你会看到一系列简单的按钮和菜单供你选择。真的不能比这更简单了：
|
||||
|
||||
![Raspberry Pi Imager home screen][5]
|
||||
|
||||
### 可用的镜像和选项
|
||||
|
||||
默认选项包含各种树莓派型号的镜像。Raspbian 是首选，它有两个可用的选项，较小的 “Lite” 版本和较大的 “Full” 版本。LibreELEC Kodi 娱乐系统有各种特定于型号的版本。Ubuntu 18 和 19 有适用于不同树莓派型号的 32 位和 64 位版本。有一个 RPi 4 EEPROM 恢复程序，以及使用 FAT32 格式化卡的功能。最后，有一个通用的镜像安装程序选项，稍后我将进行尝试。这个简单而紧凑的程序非常方便。
|
||||
|
||||
### 安装一些镜像
|
||||
|
||||
我决定使用 16g 的 micro SD 卡。我选择了默认的 Raspbian 镜像，选择已连接的 USB/SD 设备，然后按下 WRITE。这是一个简短的演示：
|
||||
|
||||
![Raspberry Pi Imager demo][6]
|
||||
|
||||
我没有在此处发布完整信息。我相信它在下载镜像后写入，对于我的无线连接这花费了几分钟完成。该过程在完成之前先经过写入，然后经过验证周期。完成后，我弹出设备，并将卡插入到我的 RPi 3 中，然后按照通常的图形 Raspbian 安装向导和桌面环境进行设置。
|
||||
|
||||
这对我来说还不够。我每天都会下载许多 Linux，今天我还在寻找更多。我回到了[树莓派下载][3]页面，并下载了 RISC OS 镜像。这个过程几乎一样容易。下载 RISCOSPi.5.24.zip 文件，将其解压缩，然后找到 ro524-1875M.img 文件。在 “Operating System” 按钮中，我选择了 “Use Custom” 并选择了所需的镜像文件。这个过程几乎是相同的。唯一真正的区别是我必须在下载目录中搜寻并选择一个镜像。文件写完后，回到树莓派 3，RISC OS 可以使用了。
|
||||
|
||||
### 对 USB C 的抱怨
|
||||
|
||||
顺便说一句，如今有多少人对 USB C 带来的不便感到沮丧？我使用的是只有 USB C 口的 MacBook Pro，我需要不断更换适配器才能完成工作。看看这个：
|
||||
|
||||
![USB C adapter][7]
|
||||
|
||||
是的，那是一个 USB C 到 USB A 适配器，然后是一个 USB 到 SD 卡读卡器，以及一个 SD 到 micro SD 适配器。我可能可以在网上找到一些东西来简化此过程，但这是支持我家五花八门的 Mac、Windows 和 Linux 主机的部分。够了，但我希望你能从这种混乱中得到一笑。
|
||||
|
||||
### 总结
|
||||
