2 new tools for creating more accessible projects

Wednesday 22nd of March 2017 07:01:00 AM

Accessibility has been an afterthought in development for far too long. The result has been costly retrofitting, the risk of inaccessible solutions, and unhappy users.

We are where we are because developers often ignore accessibility in hopes that it will resolve on its own.

How to deploy Kubernetes on the Raspberry Pi

Tuesday 21st of March 2017 07:02:00 AM

When I became interested in ARM devices, and in the Raspberry Pi in particular, my first project was an OpenVPN server.

By having the Raspberry Pi as a secure gateway to my home network, I could use my phone to control my desktop and remotely play Spotify, open documents, and a bunch of other fun things. I used an existing tutorial for that first project because I was afraid of piping anything into the command line on my own.

Command-line document conversion tools for writers

Tuesday 21st of March 2017 07:01:00 AM

Today, we have ample tools available for editing memos, letters, essays, books, presentation slides, and other documents on our computers. This can be both an advantage and a disadvantage: on the one hand, if you don't like a piece of software, you can simply move on to another one any time; on the other hand, a lot of these tools, especially proprietary software, are fully compatible with their own formats only.

Open project collaboration from elementary to university classrooms

Monday 20th of March 2017 07:01:00 AM

The practice of teaching should be built upon collaboration and remixing content. When a friend asks us to explain something, we don't trademark our answer or deliver a monologue without asking for input. This is a simple example, but it gets to the heart of the dysfunctional design inherent in our existing education system:

Why do you use Linux and open source software?

Friday 17th of March 2017 07:01:00 AM

As I mentioned when The Queue launched, although typically I will answer questions from readers, sometimes I'll switch that around and ask readers a question. I haven't done so since that initial column, so it's overdue. I recently asked two related questions at and the response was overwhelming. Let's see how the community answers both questions, and how those responses compare and contrast to those on LQ.

A lesson in accountability from my Uber driver

Thursday 16th of March 2017 07:00:00 AM

The first thing I noticed was how nice Kyle's car was. It wasn't too fancy (a late model Toyota Camry) but inside it was spotless. We were sitting in leather seats. On the back of the passenger seat, Kyle had mounted a tablet customers could use to watch TV if they wanted (not that I was particularly interested in television during this 4:30 a.m. ride to the airport).

How to build an IoT project with Mongoose OS

Wednesday 15th of March 2017 07:01:00 AM

IoT (Internet of Things) is about connecting physical objects ("things") to the Internet. Technically, this is done by attaching a computer to a "thing." A computer is attached in a way that it can read data from the thing and report to the Internet, and also it can receive commands and control the thing's state. 

Usually, the COMPUTER is directly wired to the THING, and the COMPUTER <=> INTERNET connection could be either wired (e.g., Ethernet), or wireless (e.g., Bluetooth, Wi-Fi).

What could the computer be?

Security Leftovers

  • How To Improve The Linux System’s Security Using Firejail
    As you already know, Linux kernel is secure by default. But, it doesn’t mean that the softwares on the Linux system are completely secure. Say for example, there is a possibility that any add-ons on your web browser may cause some serious security issues. While doing financial transactions over internet, some key logger may be active in browser which you are not aware of. Even though, we can’t completely give the bullet-proof security to our Linux box, we still can add an extra pinch of security using an application called Firejail. It is a security utility which can sandbox any such application and let it to run in a controlled environment. To put this simply, Firejail is a SUID (Set owner User ID up on execution) program that reduces the risk of security breaches by restricting the running environment of untrusted applications.

Containers vs. Zones vs. Jails vs. VMs

  • Setting the Record Straight: containers vs. Zones vs. Jails vs. VMs
    I’m tired of having the same conversation over and over again with people so I figured I would put it into a blog post. Many people ask me if I have tried or what I think of Solaris Zones / BSD Jails. The answer is simply: I have tried them and I definitely like them. The conversation then heads towards them telling me how Zones and Jails are far superior to containers and that I should basically just give up with Linux containers and use VMs. Which to be honest is a bit forward to someone who has spent a large portion of her career working with containers and trying to make containers more secure. Here is what I tell them:
  • [Old] Hadoop Has Failed Us, Tech Experts Say

    The Hadoop community has so far failed to account for the poor performance and high complexity of Hadoop, Johnson says. “The Hadoop ecosystem is still basically in the hands of a small number of experts,” he says. “If you have that power and you’ve learned know how to use these tools and you’re programmer, then this thing is super powerful. But there aren’t a lot of those people. I’ve read all these things how we need another million data scientists in the world, which I think means our tools aren’t very good.”
