How Linux Makes Your Life Easier

TuxMachines - Fri, 2018-07-20 22:54

There is a popular myth that Linux is complicated and hard to use by a non-techie. While there are distros and advanced Linux functionality that do require tech skills, this doesn’t mean Linux is hard to use. On the contrary, there are lots of things in the philosophy and functionality of Linux that make a user’s life easier.

Containers: IBM, Yan Vugenfirer and HPC

TuxMachines - Fri, 2018-07-20 22:51
  • IBM attempts to graft virtual machine security onto container flexibility

    IBM researchers have developed a new flavor of software container in an effort to create code that's more secure than Docker and similar shared kernel container systems.

    Docker and its ilk are considered less secure than VMs because the compromise of a shared kernel puts all associated containers at risk. With VMs, the kernel is separate from the host kernel, which reduces the risk of collateral damage.

  • Using Linux Containers to Manage Embedded Build Environments

    Linux container technology has been proposed by companies like Resin.io as a simpler and more secure way to deploy embedded devices. And, Daynix Computing has developed an open source framework called Rebuild that uses Linux containers in the build management process of embedded IoT development. At the 2017 Open Source Summit, Daynix “virtualization expert” Yan Vugenfirer gave a presentation on Rebuild called “How Linux Containers can Help to Manage Development Environments for IoT and Embedded Systems.”

    Vugenfirer started by reminding the audience of the frustrations of embedded development, especially when working with large, complex projects. “You’re dealing with different toolchains, SDKs, and compilers all with different dependencies,” he said. “It gets more complicated if you need to update packages, or change SDKs, or run a codebase over several devices. The code may compile on your machine, but there may be problems in the build server or in the CI (continuous integration) server.”

  • Building Containers with HPC Container Maker

    Containers package entire workflows, including software, libraries, and even data, into a single file. The container can then be run on any compatible hardware that can run the container type, regardless of the underlying operating system.

    Containers are finding increased utility in the worlds of scientific computing, deep learning, HPC, machine learning, and artificial intelligence, because they are reproducible, portable (mobility of compute), user friendly (admins don’t have to install everything), and simple, and they isolate resources, reduce complexity (reduction in dependencies), and make it easy to distribute the application and dependencies.

    Using containers, you have virtually everything you need in a single file, including a base operating system (OS), the application or workflow (multiple applications), and all of the dependencies. Sometimes the data is also included in the container, although it is not strictly necessary because you can mount filesystems with the data from the container.

Debian Development and News

  • Freexian’s report about Debian Long Term Support, June 2018

    Like each month, here comes a report about the work of paid contributors to Debian LTS.

  • PKCS#11 v2.20

    By way of experiment, I've just enabled the PKCS#11 v2.20 implementation in the eID packages for Linux, but for now only in the packages in the "continuous" repository. In the past, enabling this has caused issues; there have been a few cases where Firefox would deadlock when PKCS#11 v2.20 was enabled, rather than the (very old and outdated) v2.11 version that we support by default. We believe we have identified and fixed all outstanding issues that caused such deadlocks, but it's difficult to be sure.

  • Plans for DebCamp and DebConf 18

    I recently became an active contributor to the Debian project, which has been consolidated throughout my GSoC project. In addition to the great learning with my mentors, Lucas Kanashiro and Raphäel Hertzog, the feedback from other community members has been very valuable to the progress we are making in the Distro Tracker. Tomorrow, thanks to Debian project sponsorship, I will take off for Hsinchu, Taiwan to attend DebCamp and DebConf18. It is my first DebConf and I’m looking forward to meeting new people from the Debian community, learn a lot and make useful contributions during the time I am there.

  • Building Debian packages in CI (ick)

    I develop a number of (fairly small) programs, as a hobby. Some of them I also maintain as packages in Debian. All of them I publish as Debian packages in my own APT repository. I want to make the process for making a release of any of my programs as easy and automated as possible, and that includes building Debian packages and uploading them to my personal APT repository, and to Debian itself.

  • My DebCamp/DebConf 18 plans

    Tomorrow I am going to another DebCamp and DebConf; this time at Hsinchu, Taiwan.

  • Things you can do with Debian: multimedia editing

    The Debian operating system serves many purposes and you can do amazing things with it. Apart of powering the servers behind big internet sites like Wikipedia and others, you can use Debian in your PC or laptop. I’ve been doing that for many years.

    One of the great things you can do is some multimedia editing. It turns out I love nature, outdoor sports and adventures, and I usually take videos and photos with my friends while doing such activities. And when I arrive home I love editing them for my other blog, or putting them together in a video.

32-Bit Vs. 64-Bit Operating System

TuxMachines - Fri, 2018-07-20 22:22

This has really been confusing to some people choosing between 32-bit and 64-bit systems. Head over to any operating system’s website, you will be given a choice to download either versions of the same operating system. So what is the difference? Why do we have two different versions of the same OS? Let us solve this mystery here, once and for all.

Convert video using Handbrake

TuxMachines - Fri, 2018-07-20 21:22

Recently, when my son asked me to digitally convert some old DVDs of his high school basketball games, I immediately knew I would use Handbrake. It is an open source package that has all the tools necessary to easily convert video into formats that can be played on MacOS, Windows, Linux, iOS, Android, and other platforms.

Handbrake is open source and distributable under the GPLv2 license. It's easy to install on MacOS, Windows, and Linux, including both Fedora and Ubuntu. In Linux, once it's installed, it can be launched from the command line with $ handbrake or selected from the graphical user interface. (In my case, that is GNOME 3.)

  • Hacked Passwords Being Used In Blackmail Attempt -- Expect More Of This

    This was immediately obvious as a scam from a hacked database of passwords. Besides the fact that I haven't used that particular password in ages (and even when I did, it was the password I used for "unimportant" sites), there are a whole bunch of other reasons why it was obvious that the email was fake and it would be literally impossible for the person to have whatever it was they claimed to have on me. I found it funny enough that I reached out to some other folks to see if this was getting around, and a few people told me they'd seen similar ones, noting that the final note about sending it to "9 friends" appeared to be an increase from the usual of "5" that they had seen before.

    Indeed, Brian Krebs, who is always on top of these things, wrote a story about how a bunch of people got these emails last week. That one only asked for $1400, and also promised to send it to 5 friends. It has a few other slight differences to the one I received, but is pretty clearly sent by the same person/team of people with just a few modifications. Like the ones that Krebs reported on, mine appeared to come from an outlook.com email address. As Krebs notes, he expects that this particular scam is about to get a lot more popular, and will probably use a lot more recent set of passwords:

  • Hacker Summer Camp 2018: Cyberwar?

    I actually thought I was done with the pre-con portion of my Hacker Summer Camp blog post series, but it turns out that people wanted to know more about “the most dangerous network in the world”. Specifically, I got questions about how to protect yourself in this hostile environment, like whether people should bring a burner device, how to avoid getting hacked, what to do after the con, etc.

    [...]

    There’s never a guarantee of security, but with updated devices & good security hygiene, you can survive the DEF CON networks.

  • Amazon, Reddit And Others Fail To Warn Us About Dumb Passwords

    Believe it or not, there is still a large number of people who use passwords such as “password,” “password123”, “[dog’s name]1” and others along the same lines. And in the era of sophisticated hacking, these passwords are not exactly “safe.”

Cinnamon 4.0 Desktop Environment Promises to Be Fast and Have No Screen Tearing

TuxMachines - Fri, 2018-07-20 20:43

The recently released Linux Mint 19 "Tara" operating system features the latest Cinnamon 3.8 desktop environment, which promised to enable faster launching of apps and be more snappier than previous releases. After users' reactions, Linux Mint devs now decided to continue improving Cinnamon on this front for the next major release, Cinnamon 4.0, due for release this year.

Among the "snappiness" improvements they'll want to implement in the upcoming Cinnamon 4.0 desktop environment, Clement Lefebvre mentioned the removal of Vsync to eliminate a slight delay noticed when dragging a window with the mouse cursor, as well as to use "Force Composition Pipeline" in Nvidia Settings for Nvidia graphics cards to eliminate screen tearing.
