GNU Health expands Raspberry Pi support, Megadeth's guitarist uses open source principles, and more open source news.
|
||||
======
|
||||
Catch up on the biggest open source headlines from the past two weeks.
|
||||

|
||||
|
||||
In this week’s edition of our open source news roundup, GNU Health expands to Raspberry Pis, how Megadeth's guitarist uses open source principles, and more open source news.
|
||||
|
||||
### GNU Health expands its support for Raspberry Pi
|
||||
|
||||
The GNU Health project, designed to help hospitals run on low-cost software and hardware, expanded its support for Rapsberry Pi models in its recent release [according to CNX][2]. The GNU Health Embedded version that runs on Raspberry Pis is "especially suited for remote areas without internet, academic Institutions, domiciliary units, home nursing, and laboratory stations."
|
||||
|
||||
> *"GNU Health (GH) is a free and open-source Health and Hospital Information System (HIS) that can manage the internal processes of a health institution, such as financial management, electronic medical records (EMR), stock & pharmacies or laboratories (LIMS)." *
|
||||
|
||||
GNU Health is a free and open source health and hospital information system (HIS) to help healthcare systems manage finances, pharmacies, electronic medical records (EMRs), and more. The Raspberry Pi solution supports real-time monitoring of vital signs in hospitals, and retrieve information from labs.
|
||||
|
||||
More details may be found on [the official website][3].
|
||||
|
||||
### Megadeth's guitarist brings OSS approaches to music
|
||||
|
||||
Heavy metal fans likely know Kiko Loureiro as Megadeth's guitarist. Loureiro is less known in the OSS world, but that might change soon: His new solo album is called _Open Source_.
|
||||
|
||||
"By definition, 'open source' is related to softwares [in] which the original source code is made freely available and may be redistributed and modified," Loureiro shared [in a recent interview.][4] "It brings us a higher sense of community, enhances our creativity and creates new possibilities."
|
||||
|
||||
In true open source fashion, Loureiro is running an Indiegogo fundraiser to [keep his album][5] independent. His fundraiser emphasizes the "Open Source Mentality," which includes making his song's stems available for listeners to remix.
|
||||
|
||||
### The Linux Foundation partners with Harvard for a FOSS contributor security survey
|
||||
|
||||
The Linux Foundation's Core Infrastructure Initiative (CII) launched [a survey for FOSS contributors][6] addressing security concerns in open source. CII developed the survey in partnership with the Laboratory for Innovation Science at Harvard (LISH). FOSS contributors can [take the survey][7] through early August.
|
||||
|
||||
This new survey follows [the Census II analysis and report][8], which assessed popular FOSS components for vulnerabilities. David A. Wheeler, The Linux Foundation's director of open source supply chain security, said the survey is essential since open source solutions are used so widely now.
|
||||
|
||||
Along with its reports and surveys, CII built a [Best Practices badge program][9] that encourages developers to audit their solutions for security threats.
|
||||

The ultimate guide to contributing to open source, an unparallelled reliance on Linux, 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.
|
||||
|
||||
## [How to Contribute to Open Source: The Ultimate Guide][2]
|
||||
|
||||
> “The biggest challenge for most people is that they don’t identify their areas of interest and where they can help us. They come to the project and ask, ‘How can I help?’” he said. “Instead, they could say, ‘This is the skill set I’d like to achieve.’ For example, ‘I’d like to develop some specific functionality for this piece of the project.’”
|
||||
|
||||
**The impact**: Saying "I want to contribute to open source" is a bit like saying "I want to work in the not-for-profit sector". Open source is a means to an end, and there is almost certainly a project working toward the end you care about that could use the skills you have.
|
||||
|
||||
## [Vulnerability Scoring Struggles to Remain Viable in the Era of Cloud Native Computing][3]
|
||||
|
||||
> To this claim, Danen said, “It was designed to indicate the severity of a flaw relative to other flaws. Nowhere will you see it described, by FIRST who created it, as a means of assessing risk. So yes, reliable to describe the mechanics of a vulnerability, but wholly inadequate to describe the risk of the vulnerability to a particular organization or environment.”
|
||||
|
||||
**The impact**: Using the [Common Vulnerability Scoring System][4] (CVSS) classification systems for vulnerabilities is becoming more difficult. Non-experts will usually use a number that describes something in the easiest possible way. The challenge is for experts is to make sure that the easiest possible way is also the right way.
|
||||
|
||||
## [The rise of parallel serverless compute][5]
|
||||
|
||||
> So why isn’t everything fast, amazing, and running this way already? One of the challenging parts about this today is that most software is designed to run on single machines, and parallelization may be limited to the number of machine cores or threads available locally. Because this architecture & “serverless compute” is so new (_cough cough 2014_), most software is not designed to leverage this approach. I see this changing in the future as more become aware of this approach.
|
||||
|
||||
**The impact**: It is actually hard to think scalably and takes a lot of practice to mentally understand what can be done alongside other things and what has to be done sequentially.
|
||||
|
||||
## [From Earth to orbit with Linux and SpaceX][6]
|
||||
|
||||
> Ordinary? Yes, ordinary. You see, spacecraft CPUs are far from the newest and greatest. They're developed for spacecraft, which takes years -- even decades -- to go from the drafting board to launch. For example, the International Space Station (ISS) runs on 1988-vintage 20 MHz Intel 80386SX CPUs. We don't know, however, what chips the Falcon 9 uses. Chances are, though, their design is at least a decade older than what you'd buy at a Best Buy now.
|
||||
|
||||
**The impact**: If your time horizon is measured in decades, there is a good chance Linux is your best option for a stable operating system.
|
||||
|
||||
## [Why the Success of Edge Computing Relies on a Linux Legacy][7]
|
||||
|
||||
> For edge computing innovation, we need to be thinking more about how we create sustainable solutions and technologies given how many deployments will require a longer life cycle and are more tightly bound to hardware and equipment refreshes. The path of innovation leads from Linux to and through the network edge. Companies that follow this approach will be better positioned to leverage the promise and power of the edge while avoiding fragmentation and lock-in.
|
||||
|
||||
**The impact**: Edge devices can't (shouldn't?) be ephemeral; to get the value we're promised by cheap, always on, always monitoring, always streaming devices they really need to be reliable over time. Linux = sustainability.
|
||||
|
||||
_I hope you enjoyed this list and come back next week for more open source community, market, and industry trends._

Use this script to find a Raspberry Pi on your network
|
||||
======
|
||||
Identify a specific Raspberry Pi in your cluster with a script that
|
||||
triggers an LED to flash.
|
||||
![Raspberries with pi symbol overlay][1]
|
||||
|
||||
We've all been there. "I'm going to get this [Raspberry Pi][2] to try out. They look kinda cool." And then, like tribbles on an Enterprise, suddenly you have [Kubernetes clusters][3] and [NFS servers][4] and [Tor proxies][5]. Maybe even a [hotel booking system][6]!
|
||||
|
||||
Pis cover the desk. They spill out onto the floor. Carrier boards for Raspberry Pi compute modules installed into lunchboxes litter the shelves.
|
||||
|
||||
…or maybe that's just me?
|
||||
|
||||
I'll bet if you have one Raspberry Pi, you've got _at least_ two others, though, and gosh darn it, they all look the same.
|
||||
|
||||
This was the situation I found myself in recently while testing a network filesystem (NFS) server I set up on one of my Raspberry Pis. I needed to plug in a USB hard drive, but … to which one? Ol' Lingonberry Pi was the chosen host, and I was SSH'd into her, but which actual, _physical_ RPi was she? There was no way of knowing…
|
||||
|
||||
Or was there?
|
||||
|
||||
![Raspberry Pis stacked up in cluster cases][7]
|
||||
|
||||
So, so many Raspberry Pis. Which one is Lingonberry? (Chris Collins, [CC BY-SA 4.0][8])
|
||||
|
||||
At a previous job, I sometimes worked on servers in our data centers, and some of them had a neat feature: an ID button on the front of the server that, when pressed, started an LED flashing on the front and back of the server. If I needed to deal with the other side of the server, I could press the ID button, then walk _allllll_ the way around to the other side of the rack, and easily find the right server.
|
||||
|
||||
I needed something like this to find Lingonberry.
|
||||
|
||||
There aren't any buttons on the Pis, but there are LEDs, and after a quick Google search, I learned that [one of them is _controllable_][9]. _Cue maniacal laughter._
|
||||
|
||||
There are three important bits to know. First, the LED path: on Raspberry Pis, at least those running Ubuntu 20.04, the front (and user-controllable) LED is found at `/sys/class/leds/led0`. If you navigate to it, you'll find it is a symlink to a directory that has a number of files in it. The two important files are `trigger` and `brightness`.
|
||||
|
||||
The `trigger` file controls what lights up the LED. If you `cat` that file, you will find a list:
|
||||
|
||||
```
|
||||
none usb-gadget usb-host rc-feedback rfkill-any
|
||||
rfkill-none kbd-scrolllock kbd-numlock kbd-capslock

|
||||
unimac-mdio--19:01:100Mbps unimac-mdio--19:01:10Mbps
|
||||
```
|
||||
|
||||
|
||||
The item in brackets indicates what triggers the LED; in the example above, it's [mmc0]—the disk activity for when the SD card plugged into the Raspberry Pi. The trigger file isn't a normal file, though. Rather than editing it directly, you change the trigger by echoing one of the triggers into the file.
|
||||
|
||||
|
||||
To identify Lingonberry, I needed to temporarily disable the [mmc0] trigger, so I could make the LED work how I wanted it to work. In the script, I disabled all the triggers by echoing "none" into the trigger file:
|
||||
|
||||
[code]
|
||||
|
||||
```
|
||||
# You must be root to do this
|
||||
$ echo none >trigger
|
||||
|
||||
$ cat trigger
|
||||
[none] usb-gadget usb-host rc-feedback rfkill-any rfkill-none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock timer oneshot disk-activity disk-read disk-write ide-disk mtd nand-disk heartbeat backlight gpio cpu cpu0 cpu1 cpu2 cpu3 default-on input panic mmc1 mmc0 bluetooth-power rfkill0 unimac-mdio--19:01:link unimac-mdio--19:01:1Gbps unimac-mdio--19:01:100Mbps unimac-mdio--19:01:10Mbps
|
||||
```
|
||||
|
||||
|
||||
```
|
||||
In the contents of the trigger file above, you can see [none] is now the selected trigger. Now the LED is off and not flashing.
|
||||
|
||||
|
||||
Next up is the brightness file. You can control whether the LED is on (1) or off (0) by echoing either 0 or 1 into the file. Alternating
