Linux distros and software bugs

Linux is one of the best operating systems around, but no OS is perfect. All operating systems end up having bugs of one kind or another, including your favorite Linux distributions.

A writer at MakeUseOf has listed six reasons why Linux distributions often have their share of bugs.

Bertel King Jr. reports for MakeUseOf:

I’ve been a long-time GNOME user, but for the past few months, I was in a loving relationship with Elementary OS. I found much to love in the minimalist Linux-based operating system, and I encouraged readers to give it a try.

But that has changed. The number of bugs I encountered grew over time, and I’ve recently had enough. As a freelance writer, the only thing I need is a working laptop. If that’s not reliable, then I’m wasting time trying to fix the one tool my job requires.

Networking has always been one of the most persistent headaches when working with containers. Even Kubernetes—fast becoming the technology of choice for container orchestration—has limitations in how it implements networking. Tricky stuff like network security is, well, even trickier.

Now an open source project named Cilium, which is partly sponsored by Google, is attempting to provide a new networking methodology for containers based on technology used in the Linux kernel. Its goal is to give containers better network security and a simpler model for networking.

Has Ubuntu become boring?

Ubuntu has long been one of the best known and most popular Linux distributions. But has it become too boring and predictable to retain the interest of users?

One writer at OMG Ubuntu asked that question after looking at a chart of Google search volume for Ubuntu from 2004 to 2017.

Joey Sneddon reports for OMG Ubuntu:

This graph represents Google search volume for Ubuntu (the OS) from 2004 until now, 2017. Looking at the image it is hard to not conclude one thing: that interest in Ubuntu has peaked.

But has it?

I think there are a couple of possible reasons why people Google for information on or about Ubuntu less than they used to.

Roughly 26 years after Linux pushed open source into mainstream enterprise adoption, we're still debating how big a role open source should play -- at least, some people are.

Developers aren't in that group: Open source has become part of the "furniture" for them, essential to data infrastructure (Hadoop, Spark, and so on), mobile (Android), operations (Docker, Kubernetes), machine learning (TensorFlow, Mahout), and more.

The PR world, however, didn't get the memo. Canonical, the company behind Ubuntu, sent out a note this past week arguing that companies that "don't jump on the open source bandwagon" risk being "left behind." SAS's PR team, by contrast, put out a report offering helpful guidelines: Make sure your software portfolio contains no more than 40 percent open source or face potential exposure to all sorts of security, cost, and other problems.

Super Mario Run comes to Android on March 23

Super Mario Run was a big hit for Nintendo on iOS devices, and now it will finally become available for Android users on March 23. You can preorder Super Mario Run today on the Google Play store.

Eddie Makuch reports for GameSpot:

Super Mario Run will launch for Android platforms on March 23, Nintendo has announced.

Back in January, Nintendo confirmed that Super Mario Run would arrive for Android in March, but this is the first we're hearing of a specific date. The game arrives with the Version 2.0.0 update, though no other details about what the update will contain were shared (via DualShockers).

Linux Mint and security problems

Linux Mint has been lambasted by some in the media for security problems over the last few years. But how accurate are such perceptions? Does Linux Mint really suffer from security problems or is it all much ado about nothing?

A local privilege esclation flaw has been fixed in the Linux kernel, but several upstream distributions have yet to release updates. Administrators should plan on mitigating the vulnerability on Linux servers and workstations themselves and monitor the distributions for their update plans.

The race condition flaw in the n_hdlc driver (drivers/tty/n_hdlc.c) in the Linux kernel through 4.10.1 (CVE-2017-2636) can lead to a double-free error in n_hdlc_release() when accessing the n_hdlc.tbuf list, said Alexander Popov, a researcher at Russia-based Positive Technologies who found and reported the flaw. A local, unprivileged user able to set the HDLC line discipline on the tty device could exploit this flaw and gain increased privileges over the affected system or cause a denial-of-service condition.

Pivotal and Google have launched Project Kubo to apply Pivotal's Bosh tool for deploying and managing cloud software to Google's Kubernetes container orchestration platform.

Currently in an alpha release stage, Kubo instantiates, deploys, and manages Kubernetes clusters on any cloud. Pivotal has been working on the project with members of the Google Cloud platform team.

Kubo can be used with existing production applications written in specific languages, and it can access platform primitives. Bosh, featured as part of Cloud Foundry, provides an open source tool chain for managing large-scale distributed services. It offers a combination of a virtual machine build tool, configuration and health management, and logging. Bosh has been used to build consistent, self-healing environments with zero downtime, Seroter said.

Which Linux distros should newbies use?

Linux has a bad rap as a daily driver – the programs aren’t written to run on Linux, it’s tricky to install stuff, and so on. But it might surprise people who think along those lines to learn that plenty of the distributions out there are actually quite simple to use. Here’s our latest appreciation of the desktop Linux landscape.

Microsoft Windows may be the dominant player on the desktop, but the rapidly increasing open source software market—especially for admin and dev tools—clearly favors Linux. Not to mention the mobile market, where Android uses Linux variants. If you’re a developer on Windows, the drumbeat to get hip to Linux capabilities keeps getting louder.

Over the years, Microsoft has introduced various workarounds for using Linux capabilities on Windows, such as PowerShell with SSH and Cygwin and MSYS. Running Linux inside a virtual machine is another option. But VMs consume a significant amount of resources and don’t provide a first-class Linux experience, as you can’t edit local files or get full access to local drives, for example.

Chrome: The fastest web browser for Linux?

Linux offers a great range of choices when it comes to web browsers, there really is a browser out there for everybody. But which Linux browser is the fastest?

A writer at ZDNet ran some tests and came to the conclusion that Google's Chrome is the best choice for Linux users that want a really fast web browser.

SJVN reports for ZDNet:

Firefox is easily the most popular Linux web browser. In the recent LinuxQuestions survey, Firefox took first place with 51.7 percent of the vote. Chrome came in second with a mere 15.67 percent. The other browsers all had, at most, scores in single percentages. But is Firefox really the fastest browser? I put them them to the test, and here's what I found.

Earlier this week, NASA opened up a bunch of its internal software to the public: physics simulations, operational management, embedded systems control, and many other tasks you'd associate with the space program.

Some of the software is for general-purpose applications, such as machine learning and data processing, that would interest everyone from a 1,000-person enterprise to a startup with highly specific needs.

Here are five of the packages that caught our eye. The page numbers indicate where each item can be found in the catalog, and the links lead to descriptions of each package on the software.nasa.gov site. Note that not all software is available for use outside of the United States, and not all of it is open source.

This article is part of a weekly series where I'll create new projects using Raspberry Pi 3. The first article of the series focusses on getting you started and will cover the installation of Raspbian, with PIXEL desktop, setting up networking and some basics.

What you need:

  • A Raspberry Pi 3
  • A 5v 2mAh power supply with mini USB pin
  • Micro SD card with at least 8GB capacity
  • Wi-Fi or Ethernet cable
  • Heat sink
  • Keyboard and mouse
  • a PC monitor
  • A Mac or PC to prepare microSD card.

There are many Linux-based operating systems available for Raspberry Pi that you can install directly, but if you're new to the Pi, I suggest NOOBS, the official OS installer for Raspberry Pi that simplifies the process of installing an OS on the device.
