Keeping tech free
For all you open source data scientists out there, this hour-long recorded webinar explains the big data tools and services you can use on Amazon. I learned a lot of data science lingo watching this video.
On Wednesday, when Linus Torvalds was interviewed as the opening keynote of the day at LinuxCon 2016, Linux was a day short of its 25th birthday. Interviewer Dirk Hohndel of VMware pointed out that in the famous announcement of the operating system posted by Torvalds 25 years earlier, he had said that the OS “wasn’t portable,” yet today it supports more hardware architectures than any other operating system. Torvalds also wrote, “it probably never will support anything other than AT-harddisks.”
“You have to realize the background is that it was a completely personal project,” Torvalds explained. “I expected other people to be interested from a theoretical standpoint. Students of operating systems might want to look at ‘here’s another operating system we can look at.’ That was my expectation, which meant that the kind of hardware I had was the only hardware that it ran on.”
The last LinuxCon: This year’s LinuxCon, held in the city of Toronto which is one of my favorite old haunts, was the last love fest for Linux under the name LinuxCon, which had come to be synonymous for a certain type of Linux festival. In a way, it’s fitting this should be the last as the show ended on the day before Linux’s 25th birthday and was, in many ways, a celebration of the first quarter century of Linux. In another way it’s a crying shame. LinuxCon has come to stand for the community spirited nature of Linux, even though backed by the Linux Foundation, which becomes less of a community organization with the passing of each year.
Community, Hardware, Maker Movement and Video
Lady Ada and Philip Torrone are both legendary makers and exemplary sharers of hacks and tips. Their weekly “Show-And-Tell” Google Hangout is always fascinating. These Hangouts are archived to YouTube.
Security expert and co-creator of the Linux-hardening (and now Unix-hardening) project Bastille Linux. That’s Jay Beale. He’s been working with Linux, and specifically on security, since the late 1980s. The greatest threat to Linux these days? According to Beale, the thing you really need to watch out for is your Android phone, which your handset manufacturer and wireless carrier may or may not be good about updating with the latest security patches. Even worse? Applications you get outside of the controlled Google Play and Amazon environments, where who-knows-what malware may lurk.
All Macintosh computers from about 2006 onwards were made using Intel CPUs and installing Linux on these computers is a breeze. You don’t need to download any Mac specific distro — just choose your favorite distro and install away. About 95 percent of the time you’ll be able to use the 64-bit version of the distro. On CoreDuo Macs, from 2006, you’ll need to use a 32-bit version.
Here is a screencast video I made on a revived Macbook that came into my hands recently. I downloaded Linux Mint 18 Xfce 64-bit ISO, burned it to DVD, inserted it into the Macbook (after the Macbook was turned on) and then booted the Macbook from DVD by holding the the letter “C” (which tells the Mac to boot from the optical drive).
“Linux. We made it. Twenty-five years.”
With these words Jim Zemlin, the executive director of the Linux Foundation, opened up LinuxCon North America, this year being held on the northwest shore of Lake Ontario in Toronto. As expected, the opening keynote address was a 25 minute pep rally that was long on the enterprise and short on the desktop or any other area where Linux is important but not lining anyone’s pockets with cash.
If you’re a WordPress developer, Sal Ferrarello (@salcode) of Reading, PA, explains how to install Composer, use it with a plugin or a theme and use it with a WordPress project. This video is from his WordCamp Philly 2015 talk.
The Open Invention Network — OIN, as its friends call it — “is a defensive patent pool and community of patent non-aggression which enables freedom of action in Linux.” That’s what it says (among other things) on the front page of the organization’s website. Basically, if you join OIN (which costs $0) you agree not to sue other members over Linux and Android-related patents, and in return they promise not to sue you. Google, IBM, and NEC are the top three members shown on OIN’s “community” page, which lists over 2,000 members/licensees ranging from Ford to one-person Android app developers.
My introduction to the world of single board computers started with the Raspberry Pi and an attempt to spin up a media server. Once the media server was established, the GPIO pins began to peek my interest and other projects were born. As I learned more about GPIO and electronics, I discovered there existed boards other than the Raspberry Pi that I could program to take my projects to another level.
Two boards I began to work with were the Arduino and the BeagleBone Black. While I do like the BeagleBone Black, it’s the Arduino that has really honed my skills with electronics. The Raspberry Pi is all the rave of the tech world currently, but I thought I would take a moment to talk about some recent interesting stories about the board that everyone seems to have forgotten.
The Chromebook Pixel of 2013 is a lovely computer. Want to make it even lovelier? Install Ubuntu on it. This well-done tutorial video shows and explains all the steps.

In three years time, the Chromebook Pixels of 2013 will be six years old and you’ll be able to buy one quite affordably on eBay.
