Install Anaconda Python and Jupyter Notebooks for Data Science

Getting started with Anaconda

To explain what is Anaconda, we will quote its definition from the official website:

Anaconda is a free, easy-to-install package manager, environment manager and Python distribution with a collection of 1,000+ open source packages with free community support. Anaconda is platform-agnostic, so you can use it whether you are on Windows, macOS or Linux.

It is easy to secure and scale any data science project with Anaconda as it natively allows you to take a project from your laptop directly to deployment cluster. A complete set of features can be shown here with the official image as well:

Anaconda Enterprise

Anaconda Enterprise

To show in brief what Anaconda is, here are some quick points:

  • It contains Python and hundreds of packages which are especially useful if you are getting started or experienced with Data Science and Machine Learning
  • It comes with conda package manager and virtual environments which development very easy
  • It allows you to get started with development very fast without wasting your time to setup tools for Data Science and Machine Learning

You can install Anaconda from here. It will automatically install Python on your machine so you don’t have to install it separately.

Anaconda vs Jupyter Notebooks

Whenever I try to discuss Anaconda with people who are beginners with Python and Data Science, they get confused between Anaconda and Jupyter Notebooks. We will quote the difference in one line:

Anaconda is package manager. Jupyter is a presentation layer.

Anaconda tries to solve the dependency hell in python—where different projects have different dependency versions—so as to not make different project dependencies require different versions, which may interfere with each other.

Jupyter tries to solve the issue of reproducibility in the analysis by enabling an iterative and hands-on approach to explaining and visualizing code; by using rich text documentation combined with visual representations, in a single solution.

Anaconda is similar to pyenv, venv and minconda; it’s meant to achieve a python environment that’s 100% reproducible on another environment, independent of whatever other versions of a project’s dependencies are available. It’s a bit similar to Docker, but restricted to the Python ecosystem.

Jupyter is an amazing presentation tool for analytical work; where you can present code in “blocks,” combines with rich text descriptions between blocks, and the inclusion of formatted output from the blocks, and graphs generated in a well-designed matter by way of another block’s code.

Jupyter is incredibly good in analytical work to ensure reproducibility in someone’s research, so anyone can come back many months later and visually understand what someone tried to explain, and see exactly which code drove which visualization and conclusion.

Often in analytical work, you will end up with tons of half-finished notebooks explaining Proof-of-Concept ideas, of which most will not lead anywhere initially. Some of these presentations might months later—or even years later—present a foundation to build from for a new problem.

Using Anaconda and Jupyter Notebook from Anaconda

Finally, we will have a look at some commands with which we will be able to use Anaconda, Python and Jupyter on our Ubuntu machine. First, we will download the installer script from the Anaconda website with this command:

curl -O -k https://repo.anaconda.com/archive/Anaconda3-5.2.0-Linux-x86_64.sh

We also need to ensure the data integrity of this script:

sha256sum Anaconda3-5.2.0-Linux-x86_64.sh

We will get the following output:

Check Anaconda integrity

Check Anaconda integrity

We can now run the Anaconda script:

bash Anaconda3-5.2.0-Linux-x86_64.sh

Once you accept the terms, provide a location for installation of packages or just hit Enter for it to take the default location. Once the installation is completed, we can activate the installation with this command:

Finally, test the installation:

Making an Anaconda Environment

Once we have a complete installation in place, we can use the following command to create a new environment:

conda create –name my_env python=3

We can now activate the environment we made:

With this, our command prompt will change, reflecting an Active Anaconda environment. To continue with setting up a Jupyter environment, continue with this lesson which is an excellent lesson on How to install Jupyter Notebooks on Ubuntu and start using them.

Conclusion: Install Anaconda Python and Jupyter Notebooks for Data Science

In this lesson, we studied how we can install and start using the Anaconda environment on Ubuntu 18.04 which is an excellent environment manager to have, especially for beginners for Data Science and Machine Learning. This is just a very simple introduction of many lessons to come for Anaconda, Python,Data Science and Machine Learning. Share your feedback for the lesson with me or to LinuxHint Twitter handle.

TimelineJS: An interactive, JavaScript timeline building tool

TimelineJS 3 is an open source storytelling tool that anyone can use to create visually rich, interactive timelines to post on their websites. To get started, simply click “Make a Timeline” on the homepage and follow the easy step-by-step instructions.

TimelineJS was developed at Northwestern University’s KnightLab in Evanston, Illinois. KnightLab is a community of designers, developers, students, and educators who work on experiments designed to push journalism into new spaces. TimelineJS has been used by more than 250,000 people, according to its website, to tell stories viewed millions of times. And TimelineJS3 is available in more than 60 languages.

Joe Germuska, the “chief nerd” who runs KnightLab’s technology, professional staff, and student fellows, explains, “TimelineJS was originally developed by Northwestern professor Zach Wise. He assigned his students a task to tell stories in a timeline format, only to find that none of the free available tools were as good as he thought they could be. KnightLab funded some of his time to develop the tool in 2012. Near the end of that year, I joined the lab, and among my early tasks was to bring TimelineJS in as a fully supported project of the lab. The next year, I helped Zach with a rewrite to address some issues. Along the way, many students have contributed. Interestingly, a group of students from Victoria University in Wellington, New Zealand, worked on TimelineJS (and some of our other tools) as part of a class project in 2016.”

“In general, we designed TimelineJS to make it easy for non-technical people to tell rich, dynamic stories on the web in the context of events in time.”

Users create timelines by adding content into a Google spreadsheet. KnightLab provides a downloadable template that can be edited to create custom timelines. Experts can use their JSON skills to create custom installations while keeping TimelineJS’s core functionality.

This easy-to-follow Vimeo video shows how to get started with TimelineJS, and I used it myself to create my first timeline.

Open sourcing the Adirondacks

Reid Larson, research and scholarly communication librarian at Hamilton College in Clinton, New York, began searching for ways to combine open data and visualization to chronicle the history of Essex County (a county in northern New York that makes up part of the Adirondacks), in the 1990s, when he was the director of the Essex County Historical Society/Adirondack History Center Museum.

“I wanted to take all the open data available on the history of Essex County and be able to present it to people visually. Most importantly, I wanted to make sure that the data would be available for use even if the applications used to present it are no longer available or supported,” Larson explains.

Now at Hamilton College, Larson has found TimelineJS to be the ideal open source program to do just what he wanted: Chronicle and present a visually appealing timeline of selected places.

“It was a professor who was working on a project that required a solution such as Timeline, and after researching the possibilities, I started using Timeline for that project and subsequent projects,” Larson adds.

TimelineJS can be used via a web browser, or the source code can be downloaded from GitHub for local use.

“I’ve been using the browser version, but I push it to the limits to see how far I can go with it, such as adding my own HTML tags. I want to fully understand it so that I can educate the students and faculty at Hamilton College on its uses,” Larson says.

An open source Eagle Scout project

Not only has Larson used TimelineJS for collegiate purposes, but his son, Erik, created an interactive historical website for his Eagle Scout project in 2017 using WordPress. The project is a chronicle of places in Waterville, New York, just south of Clinton, in Oneida County. Erik explains that he wants what he started to expand beyond the 36 places in Waterville. “The site is an experiment in online community building,” Erik’s website reads.

Larson says he did a lot of the “tech work” on the project so that Erik could concentrate on content. The site was created with Omeka, an open source web publishing platform for sharing digital collections and creating media-rich online exhibits, and Curatescape, a framework for the open source Omeka CMS.

Larson explains that a key feature of TimelineJS is that it uses Google Sheets to store and organize the data used in the timeline. “Google Sheets is a good structure for organizing data simply, and that data will be available even if TimelineJS becomes unavailable in the future.”

Larson says that he prefers using ArcGIS over KnightLab’s StoryMap because it uses spreadsheets to store content, whereas StoryMap does not. Larson is looking forward to integrating augmented reality into his projects in the future.

Create your own open source timeline

I plan on using TimelineJS to create interactive content for the Development and Alumni Relations department at Clarkson University, where I am the development communications specialist. To practice with working with it, I created a simple timeline of the articles I’ve written for Opensource.com:

As Reid Larson stated, it is very easy to use and the results are quite satisfactory. I was able to get a working timeline created and posted to my WordPress site in a matter of minutes. I used media that I had already uploaded to my Media Library in WordPress and simply copied the image address. I typed in the dates, locations, and information in the other cells and used “publish to web” under “file” in the Google spreadsheet. That produced a link and embed code. I created a new post in my WordPress site and pasted in the embed code, and the timeline was live and working.

Of course, there is more customization I need to do, but I was able to get it working quickly and easily, much as Reid said it would.

I will continue experimenting with TimelineJS on my own site, and when I get more comfortable with it, I’ll use it for my professional projects and try out the other apps that KnightLab has created for interactive, visually appealing storytelling.

Pinguy OS Puts On a Happier GNOME 3 Face | Reviews

By Jack M. Germain

Pinguy OS Puts On a Happier GNOME 3 Face

Pinguy OS 18.04 is an Ubuntu-based distribution that offers a non-standard GNOME desktop environment intended to be friendlier for new Linux users.

This distro is a solid Linux OS with a focus on simple and straightforward usability for the non-geek desktop user. If you do not like tinkering with settings or having numerous power-grabbing fancy screen animations, Pinguy OS could be a good choice.

The GNOME desktop is the only user interface option, but Pinguy OS’ developer, Antoni Norman, tweaked the desktop environment with some different software options not usually packaged with GNOME.

His refusal to settle for the run-of-the-mill software typical of mainstream GNOME choices is one of this distro’s strongest features. The developer gives you better application options to create the best user experience within the modified GNOME environment.

Pinguy OS is a great pick for beginning Linux users because it is easy to use and offers a satisfying experience. It is also a no-nonsense computing platform for seasoned Linux users who want a GNOME environment that makes more sense.

Pinguy OS comes with user-friendly enhancements and out-of-the-box support for multimedia codecs and browser plugins. The modified GNOME user interface has enhanced menus, panels and dock bars. It includes a handpicked selection of popular desktop applications for many common computing tasks.

Sensible Modernizing

I last looked at Pinguy OS four years ago and found it both useful and easy to use. The developer offers a major upgrade about once yearly. This latest release, which arrived earlier this month, shows significant updating.

For instance, it includes GNOME 3.28. The developer tweaked many of the components to ensure a fast and modern OS. Gone are the gEdit text editor in favor of Pluma. In addition to providing better performance, Pluma is a suitable clone replacement. The file manager app is Nemo 3.8.3.

No email client is bundled with this latest release, but Thunderbird is readily available from repositories. The developer suggests using the GNOME email notifications, which is part of the GNOME desktop and works once you enter online account info into the GNOME account panel.

One of the benefits of running Pinguy OS used to be its support for 32-bit systems. However, the latest tweaking done to Pinguy OS made 32-bit versions a bad user experience. This latest release does not run on very old hardware.

Changes That Work

Earlier versions of Pinguy OS ran Docky, an aging launch dock app. It did not mesh well with the latest Pinguy OS build, so gone it is. In its place are Simple Dock and Places Status Indicator.

Pinguy OS 18.04 panel bar

Pinguy OS 18.04 combines application listings, system panel bar tools and workspace switcher into one multifunction panel. Plus, it provides a panel bar for notifications and a Simple Dock for quick launch.

Simple Dock and Places Status Indicator are GNOME extensions. Like Docky, Simple Dock places a quick launch bar at the bottom of the screen. Places Status Indicator adds a menu for quickly navigating places in the system.

Simple dock at the bottom of the screen and the panel bar across the top of the screen provide easy access to all system tools. The menu button at the left of the top panel has additional tweaks and improvements.

Some of the default GNOME apps have been replaced with MATE versions. This is another example of why Pinguy OS is not just another retread built on standard GNOME 3.

Earlier versions came with the Conky desktop applets, but all the adjusting done in the Pinguy OS 18.04 made it a distraction at best. The developer reasoned that the OS did not need Conky because it confused new users.

I can not agree more. I have found Conky to be clunky. Most of its displays focused on system readouts. Putting them on a desktop just adds to the clutter.

Under the Hood

Pinguy OS is basically Linux Mint infrastructure under the covers, but the GNOME 3 environment is redesigned with many nice usability features. The tweaking in this latest Pinguy OS goes well beyond the GNOME 3 you see in Linux Mint, however.

Pinguy OS has only one desktop flavor. It comes in two options, though: full version or the mini edition. This supports the developer’s goal of making an uncomplicated desktop environment.

The mini option gives you less prepackaged software, but you can add the software not included with a few mouse clicks.

This release uses Linux Kernel 4.15.0-23-generic. It also includes OpenGL version string 3.1 Mesa 18.1.1.

If you are a game player who fancies Window games, you will like the inclusion of Winepak’s repository. This makes it easy to install your favorites.

Pinguy OS 18.04 also ships with a new GDM and GTK Theme, which contributes greatly to giving the OS a more modern look.

Look and Feel

The desktop itself is clutter-free. You can not place icons there. That is a feature (or not) of the GNOME 3 desktop.

However, it also reinforces one of the distro’s driving principles. The goal of Pinguy OS is to give users a clean desktop with a fine-tuned interface that works without confusion. This distro does that.

Simplicity is not the only distinguishing trait. Pinguy OS is a thing of beauty. Pinguy OS comes with an eye-catching collection of artwork that randomly displays as a new background every five minutes or so.

Pinguy OS 18.04 desktop weather applet

Pinguy OS has a clutter-free desktop and a handy weather applet built into the top panel.

This process is controlled by the Variety application. You can change the timing interval and other options for the background images in the Variety Preferences panel.

Pinguy provides a reasonably solid out-of-the-box experience, but the GNOME 3 desktop limits functionality for the sake of simplicity. That is an important distinction.

A panel bar sits at the top of the screen. It holds the traditional menu button in the left corner and system notification icons on the right half of the bar. You can not add or remove any items from the bar.

A Matter of Taste

Do not get me wrong. Placing simplicity above functionality is a point of user perspective about the GNOME 3 desktop — I do not mean that as a criticism.

GNOME 3 is the foundation under several popular desktop environments. What you can see and do with it is a matter of what the developer does. This developer does a lot.

Pinguy OS is not your typical plain-Jane GNOME desktop. Pinguy OS is a solid, functional OS.

New Linux users will not be frustrated by it, but seasoned Linux users might want an advanced setting tool, which does not exist.

My personal preference is a bottom panel that puts notifications, quick launch icons, and a virtual workplace switcher applet a single mouse click at hand. I’d like to see a few icon launchers on the desktop for added convenience.

That is my comfort zone. Standard GNOME 3 dumbs down the process of navigating quickly. It unnecessarily hides access to moving around open applications on numerous virtual workplaces.

Pinguy OS has enough tweaking to build in a suitable workaround for such limitations. So in that regard, this distro gives you a better integration of the GNOME desktop.

Change for the Better

Earlier versions of Pinguy OS used the default full-screen display to show installed applications. The current release has a much better menu system. The far left corner of the panel bar has a Menu button and a Places button.

Click Places for a dropdown listing of folders such as downloads, documents, music, pictures and videos. Clicking on any of these opens a file manager with more options.

Click the Menu button to open a trilogy of functionality. This is a handy mechanism that pulls together what usually is done with several clicks in standard GNOME.

The Simple Dock provides quick access to a few essentials. The apps there include the Web browser, software store, terminal, trash and system monitoring tools.

Multipurpose Panel Bar

When you click the Main Menu button, a panel drops down from the top left corner of the screen. Across the top of this panel are buttons to restart the GNOME shell, suspend /shut down /log out user, lock screen, view Web bookmarks, view recent files, toggle startup apps view, and view applications in list/grid view.

A search window makes finding applications fast. As you type letters, a list of icons for matching applications appears. Click the gear button in the far right of this top row to open a GNOME Menu settings panel. It is here that you can turn on/off numerous features such as activating hot corners.

Down the left edge of the main menu panel is a list of categories that includes Frequent Apps and Favorite Apps. You see that list in the large display area in the center of the dropdown panel. Depending on whether you set grid or list view, a vertical list of program titles fills either the display area or a mini version of the full-screen display that you see in standard GNOME 3.

Built-in Workspace Switcher

What I really dislike about the usual display for virtual workspaces is having to push the mouse pointer into the top left hot corner to slide out the panel from the right edge of the screen. Pinguy OS has a much better solution.

The right edge of the Main Menu panel automatically shows the virtual workspaces in thumbnail view. What a concept! It is simple and efficient.

This approach makes it very handy to navigate among different virtual desktops with a single mouse click. Other features lets you use window actions to move an application to another workspace or jump to a new location using shortcuts.

Settings Supremacy

The top panel bar in GNOME (including Pinguy OS) does not dock open applications or provide any panel applets. That short-circuits many of the special features the panel provides in other Linux desktop environments.

However, Pinguy OS makes up for that by providing a consolidation of system settings. This is a very useful alternative.

Access the system settings from the Main Menu /System Tools /Settings. The list of settings and preferences resembles the dropdown top panel on an Android device. It is very straightforward and complete.

Pinguy OS 18.04 preference panels

A design based on simplicity puts nearly all of the system settings into an Android-style set of preference panels.

A second settings panel of sorts is available by clicking the Gear button at the far right top of the Main Menu. Click on a category to see a full panel view of preferences to turn on/off. This settings panel provides much of the functionality that would otherwise be provided in a fully functional panel bar at the top (or bottom) of the Linux screen.

Bottom Line

Pinguy OS may not satisfy power users who like to control navigation with keyboard shortcuts and advanced system settings. However, if you just want your system to work from the start, Pinguy OS has a lot going for it.

Do not let this distro’s self-avowed fervor for simplicity let you misjudge its power and usability. If you think it is too basic for serious users, your thinking might be skewed.

Even if you do not prefer the GNOME 3 desktop, give Pinguy OS a try. It is not your standard GNOME. This OS improves upon most of GNOME 3’s shortcomings. It offers a solid, better GNOME integration.

What are the Things to Do After Elementary OS Juno Installation

Elementary Juno Things to Do

Here comes Elementary OS 5 Juno which is built with ultimate care for better user experience. This time it comes with Linux 4.15 (based on Ubuntu 18.04 LTS) which brings improved hardware support and performance. Read the official release announcement and know about the added features in details.

If you already downloaded & installed elementary Juno then I will show things to do after installing elementary OS Juno for better user experience.

Things to do after installing elementary OS Juno

1) System Update

Open the command line by clicking Applications in upper left portion of the screen, and click Terminal.
To permanently become root user, type sudo su – and enter user password you specified during installation.

$ sudo su –
[sudo] password for linoxide:
[email protected]:~#

To get a list of all packages that should be updated, enter the following command

# apt-get update
Now to do the actual update, enter
# apt-get upgrade

After you accept (‘y’) the installation, it will take a while, depending on how many packages are there to be updated.

2) Gnome Tweak

Gnome tweak is a software that you can use to customize your Gnome Desktop environment such as the icons, theme, cursor theme and many other things.

# apt-get install gnome-tweaks

3) Enable tap to click for laptop users

Some Linux systems disable the tap to click so you will need to enable it in order to use it. You can enable it by going to Applications -> system settings -> Mouse & Touchpad.

4) Enable Night light

The night light feature adapts the display settings based on your location and the time of the day which reduces the amount of blue light emitted in the evenings. You can enable it by going to Applications -> system settings -> Displays. The schedule is automatic but you can set it manually

5) Configure Networking

The easiest way is through GUI-click the icon of the network in top right portion of the screen.

Click Network Settings, choose Ethernet and Edit Connections. Select Wired Connection 1 and click the tool icon

Now in IPv4 tab, enter “Manual” instead of “DHCP”, and fill in the fields for address, subnet mask, gateway, and DNS server accordingly.

6) Remote Access via SSH

To remotely connect to your server via SSH, you need to install an SSH server on your Elementary OS virtual machine.

# apt-get install openssh-server

7) LibreOffice

For a free Office alternative, install libreOffice.

# apt-get install libreoffice

After a quite lengthy installation, you will get new icons in Applications for LibreOffice Base, Cals, Draw and its other application.

8) VLC Player

The fabulous VLC player is easy to install with:

# apt-get install vlc

9) Amarok

Some people prefer to play music with Amarok music player, and it can be installed with

# apt-get install amarok

10) Audacity

One of the best audio recording and editing software on Linux is Audacity.

# apt-get install audacity

11) Thunderbird

My personal preference for mail clients on Linux as well as on Windows, Mozilla Thunderbird is available for install as well.

# apt-get install thunderbird

12) Firefox

For those of you who like Firefox web browser:

# apt-get install firefox

13) GIMP

Not really a Photoshop, but this is a fabulous graphic editing tool

# apt-get install gimp

14) FileZilla

If you need to access remote FTP connections, most of the people would recommend Filezilla.

# apt-get install filezilla

15) Skype

Skype is not available from default repositories, you need to download the installation package (.deb file) from the official download page.

# wget https://go.skype.com/skypeforlinux-64.deb

# dpkg -i skypeforlinux-64.deb

If you get errors about dependencies, and you probably will execute the following command:

# apt install -f

16) Submission Client

For great torrent client called Submission, execute:

# apt-get install transmission

17) Dropbox

For this great shared storage, go to the dropbox download page

Copy the link and download the .deb package using wget

# wget
https://www.dropbox.com/download?dl=packages/ubuntu/dropbox_2015.10.28_amd64.deb

After you most likely encountered errors, execute the following:

# apt install -f

18) GDebi

Gdebi is a tool for installation of .deb files with automatic installation of dependencies.

Ubuntu Linux 18.10 Cosmic Cuttlefish is finally available for download!

There has never been a better time to be a Linux enthusiast. There are so many great distributions from which to choose, including elementary OS 5 Juno, Linux Mint 19, and Bodhi 5.0.0. What do those aforementioned operating systems have in common? They are based on Ubuntu. To take things a step further, Canonical’s operating system is based on Debian, but I digress.

But yeah, Ubuntu is wildly popular — with both end users and other Linux distro maintainers. When a new version of the operating system is released, the world goes wild. Well, it’s time to get excited, yall! Today — after a short Beta period — Ubuntu Linux 18.10 Cosmic Cuttlefish is finally available for download!

“Codenamed ‘Cosmic Cuttlefish,’ 18.10 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs,” says Adam Conrad, Software Engineer, Canonical.

Conrad further says, “The Ubuntu kernel has been updated to the 4.18 based Linux kernel, our default toolchain has moved to gcc 8.2 with glibc 2.28, and we’ve also updated to openssl 1.1.1 and gnutls 3.6.4 with TLS1.3 support. Ubuntu Desktop 18.04 LTS brings a fresh look with the community-driven Yaru theme replacing our long-serving Ambiance and Radiance themes. We are shipping the latest GNOME 3.30, Firefox 63, LibreOffice 6.1.2, and many others.”

Sadly, according to the release notes, there are some known issues as listed below.

  • After installing Cosmic alongside Cosmic, the resized filesystem is corrupted (bug 1798562) It has not been reported to happen if the original operating system is something else than Cosmic.
  • When Ubuntu is reinstalled with preserving existing data, an error message is displayed due to “Could not get lock /target/var/cache/apt/archives/lock” (bug 1798369). The packages installed originally are not reinstalled and must be reinstalled manually. Although the user data is preserved.
  • The screen reader doesn’t read the installer when executed from a live session (bug 1797861), is not auto-enabled on first login even if it’s been enabled during installation (bug 1796275) and the pages of the first run wizard are not read properly (bug 1797868)
  • When disconnecting from VPNs, DNS resolution may become broken requiring a restart of resolved. $ sudo systemctl restart systemd-resolved.service Bug 1797415
  • In an OEM installation, during user setup, the language selected is not taken into account (bug 1798554)
  • The gnome-initial-setup Quit option from the application menu in the top bar doesn’t quit the application. If you want to quit g-i-s use quit from the dock menu instead.

Ubuntu 18.10 “Cosmic Cuttlefish” Due Out Today, Arm Launches IoT-Focused Mbed Linux, GitHub’s New Security Features, MongoDB Announces New Server Side License and Google to Charge for Apps on Android Handsets Sold in Europe

News briefs for October 18, 2018.

Ubuntu 18.10 “Cosmic Cuttlefish” expected to be released today. According to Phoronix, the
biggest change for users will be the revised default theme for the GNOME
Shell experience, now known as “Yaru”. Ubuntu 18.10 will also have the Linux
4.18 kernel, “which means better hardware support, various performance
improvements, and other optimizations compared to Ubuntu 18.04’s Linux 4.15”.

Arm launches the IoT-focused Mbed Linux OS and also extends Pelion IoT
Platform services. According to Linux.com,
Mbed Linux “combines the Linux kernel with tools and recipes from the
Intel-backed Yocto Project. The distro also integrates security and IoT
connectivity code from its open source Mbed RTOS”. In addition, the Pelion
IoT Platform “will align
with Intel’s Secure Device Onboard (SDO) provisioning technology to make
it easier for IoT vendors and customers to onboard both x86 and Arm-based
devices using a common Pelion platform. Arm also announced Pelion related
partnerships with myDevices and Arduino.”

GitHub updated its platform this week, which included many developer-centric
changes and security features, but the most notable change is the
“expansion of the Security Alerts feature, which also now supports Java and
.NET projects, on top of the original JavaScript, Ruby and Python”, ZDNet
reports
.

MongoDB
recently announced
it will be released under the new Server Side
Public License
: “The SSPL clarifies the conditions for making MongoDB
publicly available as a service, to ensure we can continue to invest in
building MongoDB for our users rather than in costly litigation over
enforcing the AGPL. All subsequent versions and patch releases to prior
versions of MongoDB made after October 16th, 2018 will be issued under the
new SSPL.”

Google plans to charge smartphone makers to pre-install apps like Gmail
and YouTube on Android handsets sold in Europe. The
Verge
quotes Android leader Hiroshi Lockheimer, “Since the
pre-installation of Google Search and Chrome together with our other apps
helped us fund the development and free distribution of Android, we will
introduce a new paid licensing agreement for smartphones and tablets shipped
into the [European Economic Area].”
