LXer: How to use getopts to parse a script options

Saturday 26th of August 2017 10:07:14 PM
Modifying a bash script behavior via runtime options, just like we normally do with command line programs, can be very useful. The bash shell provides the getopts builtin command, a standard way to achieve this. How to use it is what we will learn in this tutorial.

TuxMachines: today's leftovers

Saturday 26th of August 2017 08:23:13 PM
  • Solus 3, Ubuntu 17.10 News, Krita 3.2 & Lots of Gaming News | This Week in Linux

    Coming up on This Week in Linux, we saw some new releases from Solus, Krita, Ardour, feren OS and many more. Debian and GNOME both celebrated their Birthdays this week. We check out some cool software that lets you do Google Searches from the command-line and we'll take a look at this week's gaming news. All that and more on today's episode of This Week in Linux. I'm Michael Tunnell of TuxDigital with Your Weekly Source for Linux GNews.

  • Linux Plex Box Demo | For The Record

    In part 2 of my continuing series on reducing dependencies on streaming services like Netflix, Hulu, Amazon Kindle books and more, today I talk about how I use Plex to make my local video content more accessible. This includes some TV shows and movies I have on DVD.

  • Real world Performance Comparison of Samsung 960 EVO M.2 NVMe SSD and Transcend 2.5″ SATA III SSD on Linux

    Recently I bought a Samsung 960 EVO 500GB SSD to replace my Transcend 128GB SSD360S 2.5″ SATA III. Earlier this PC had this 128GB SATA III SSD for OS and 1TB Seagate Barracuda drive for data. I had not really utilised this 1TB well – data was just around 300GB. So to get faster system at the cost of underutilised free space, decided to buy Samsung 960 EVO 500GB to have both OS and data (Having more free space helps for better performance in case of SSD. So I am planning to add another 500GB to free up a lot of space on this newly purchased 500GB). Here I try to compare my earlier system with SATA SSD with new NVMe SSD. The rest of the configuration of PC is same for both the cases. I use KDE Neon (Ubuntu derivative) Linux Operating System.

  • Give Your Desktop An Ancient Look With 'Ubo Icons'

    You will find very few icons theme where creator work really hard to pencil icons for your desktop to make elegant. Ubo icons a great icons set drawn with ballpoint pen, then scanned and colored in GIMP. Isn't it feels great to have such hand-crafted icons specially for your desktop, the icons are not glamorous, nor glossy finish but give a unique look to your desktop.

  • Ideal OS: Rebooting the Desktop Operating System Experience

    Consider the Raspberry Pi. For 35 dollars I can buy an amazing computer with four CPU cores, each running over a gigahertz. It also has a 3d accelerator, a gig of RAM, and built in wifi & bluetooth & ethernet. For 35 bucks! And yet, for many of the tasks I want to do with it, this Raspberry Pi is no better than the 66 megahertz computer I used in college.

  • Intro To Budgie Desktop 10.4: Now With Control Center & Flexible Panel

    The latest Budgie Desktop 10.4 released at 18 August 2017 and this is a short review.  The 10.4 brings huge changes on Budgie featuring new Desktop Settings, new Raven, more flexible panel for any position, ability to add new panel and change control buttons position, default bottom-left menu at bottom panel, and so on! This review is based on Solus OS 3 and not Ubuntu Budgie (because at this day no PPA available for 10.4 yet).

  • Tales of an IT professional sailing around the Antarctic loop

    Of course, that kind of rerouting wasn’t an option. Instead, Pina i Estany accessed a remote server, downloaded and compressed all the e-mails to it, and then sent those compressed files to the ship using a piece of software called Rsync, which deals very well with unstable connections. He also wrote a script that meant if the program stopped downloading at any point, it would start again from the same place once a connection was re-established.

    “So I left this program running for eight or nine hours and then opened this huge file using Thunderbird,” he said. “With that, I was able to get all the wanted e-mails, including the permits we needed.”

  • Serverless May Kill Containers [Ed: Mac Asay is not technical. So he says a buzzword will "kill" something that's a real, working implementation. That's like saying containers will "kill" containers, only you lose control over them.]

    Kubernetes, the darling of the container world, seems set to dominate the next decade of container orchestration. That is, if containers last that long.

    While it seems obvious that containers, the heir apparent to virtual machines, should have a long shelf life, the serverless boom may actually serve to cut it short. Though serverless offerings from AWS and Microsoft are built on the backs of containers, they eliminate the server metaphor entirely (and, hence, the need to containerize that server).

  • Harvey: Hurricane Preparation Tips for Data Center Managers

    As Hurricane Harvey bears down on the Texas coast, expected to make landfall around Corpus Christi either tonight or Saturday morning as a dangerous Category 3 storm, the men and women who work in data centers in the area are undoubtedly earning overtime as they prepare for the storm’s onslaught. Keeping data centers operational during natural disasters can be critical to the health and safety of the affected area’s residents, as they supply the lines of communications for many first responders and provide access to valuable information about weather conditions and the state of the area’s infrastructure.

    During pending disasters such as this, employees from Schneider Electric’s various data center divisions can often be found on the scene, offering their expertise to help data centers successfully get through the emergency. They’re good to have around, because as the old saying goes, they’ve been there and done that — countless times.

  • 35 Blockchain Startups to Watch

    There’s a reason that blockchain startups are hot. Technologies come and go over the years and raise their share of hype, but few can match the enthusiasm that has been shown for blockchain technology.

    Blockchain is the brainchild of Satoshi Nakamoto, who may or may not be real and may or may not be one person or a group of people. All that is known is that Nakamoto is also the brains behind Bitcoin. Blockchain is in fact the technology behind Bitcoin but the two are totally separate. Blockchain provides the means to record and store Bitcoin transactions, but the blockchain technology has many uses beyond Bitcoin.

  • IBM Debuts Secure, 'Enterprise-Ready' Blockchain Platform

    For IBM, there's no time like the present for enterprises looking to build their first of potentially many blockchain applications.

    Blockchain is ready to get to work with today's introduction of the "world's first enterprise-ready blockchain platform," Angel Diaz, vice president of Developer Technology and Advocacy at IBM, told Datamation.

TuxMachines: Kernel: LWN Articles Without the Paywall Now

Saturday 26th of August 2017 08:21:59 PM
  • A canary for timer-expiration functions

    A bug that allows an attacker to overwrite a function pointer in the kernel opens up a relatively easy way to compromise the kernel—doubly so, if an attacker simply needs to wait for the kernel use the compromised pointer. There are various techniques that can be used to protect kernel function pointers that are set at either compile or initialization time, but there are some pointers that are routinely set as the kernel runs; timer completion functions are a good example. An RFC patch posted to the kernel-hardening mailing list would add a way to detect that those function pointers have been changed in an unexpected way and to stop the kernel from executing that code.

  • Scaling the kernel's MAINTAINERS file
  • Another attempt at speculative page-fault handling
  • The D-Bus Broker project

    The D-Bus Broker Project is an effort to rethink the D-Bus message bus and produce an implementation that addresses many of its longstanding problems; this project has now made its first public release. "Its aim is to provide high performance and reliability, while keeping compatibility to the D-Bus reference implementation. It is exclusively written for linux systems, and makes use of many modern features provided by recent linux kernel releases." See this post for an introduction to the project, or the GitHub page for source. This is a purely user-space implementation.

TuxMachines: Limitations of Darling and Wine (Mac OS X and Windows Software on GNU/Linux)

Saturday 26th of August 2017 08:20:11 PM
  • Lessons Learned While Building Security.framework

    Security's source code was full of incorrectly capitalized header names. This is because macOS defaults to using Case-Insensitive HFS+ by default, causing these problems to not be noticed until we tried building the source when it is on EXT4, a case-sensitive filesystem. Few people chose the case-sensitive variant of HFS+ and many software suites, including some by Adobe, flat-out refuse to be installed to case-sensitive HFS+. When APFS was announced to be the default filesystem of the upcoming macOS 10.13 High Sierra, we are very disappointed that it will still be case-insensitive by default. This problem confirms that Apple uses case-insensitive filesystems for development.

  • I tried to install SketchUp 2017 in Linux ...

    Back in the day, you really COULD install and use the likes of IE6, Word 2003, WinAmp, and other software. I was able to use SketchUp and LFS. And let's not forget DirectX! Then, Windows moved on and WINE did not. Hey, even IE7 and IE8 were tricky, to say nothing of anything more recent or complex. If you're aiming for serious stuff, you just won't succeed. WINE was designed and meant for Windows XP, and sadly, that is where and when the party ended. The test with SketchUp 2017 just adds another nail to the coffin.

    I think the WINE framework needs a complete revamp. In its current guise, it just gives false hopes to people, or keeps them running super ancient software that, in some cases, makes perfect sense, but in others, it's a complete waste of time and effort. I also find the effort of trying WINE to be painful. I am not interested in errors, messages or manual tweaks. If it can't work automagically, it's not meant to be. Since my version 1.7 test, things have even gotten worse. I might as well give up on WINE for good. I don't know. However, what it does definitely mean, and what I do know, is that for my 3D games, it will have to be Windows, I'm afraid. Article, end of.

  • Krita 3.2.0 Best Alternative To Photoshop for Ubuntu/Linux Mint

    Krita is a KDE program for sketching and painting, although it has image processing capabilities, offering an end–to–end solution for creating digital painting files from scratch by masters. Fields of painting that Krita explicitly supports are concept art, creation of comics and textures for rendering. Modelled on existing real-world painting materials and workflows, Krita supports creative working by getting out of the way and with a snappy response.

    You are using Kate or KDevelop and often editing directly the sources of Markdown files, Qt UI files, SVG files, Dot graph files and whatever else formats which are based on plain text files?

    And you are having to use a workflow to check the current state which is saving the file and (re)loading it in a separate viewer application?

    Sticklyst is a web paste tool, like pastebin, Stick Notes (paste.kde.org), build with Cutelyst and KDE Frameworks.

    Building this kind of tool has been on my TODO list for a long time, but never really put some effort into it. When the idea first came by, I decided to look at the code of http://paste.scsys.co.uk/ which is powered by a Perl Catalyst application, to my surprise the Perl module that handled syntax highlighting was a port of the code of Kate, and it even said it used Kate’s definitions.

  • GSoC ’17: Wrapping Things Up

    My GSoC project on GNOME Calendar was full of ups and downs (more ups of course).   As this was my first GSoC project I was practically new to this workflow. Having weekly meetings, pushing code on a timely basis, discussing ideas regularly with my mentor etc. made things all the more intense. There were weeks were I made more progress than expected and then there were weeks where we headed nowhere (due to lack of knowledge regarding recurrences). The reason for this was using the sparsely documented library, ‘libical‘ and deciphering the cryptic code of ‘evolution calendar‘. But in the end everything came out just fine.

TuxMachines: Purism Librem 13 v2 Linux laptop review

Saturday 26th of August 2017 04:45:53 PM

At first glance, the Purism Librem 13 v2 looks like a lot of other laptops on the market. It’s a compact notebook that measures about 0.7 inches thick, weighs about 3.3 pounds, and which has a 13.3 inch, 1920 x 1080 pixel display, a backlit keyboard, and a large touchpad.

But take a closer look at the touchpad and you’ll notice that there’s a rectangle where you’d normally find a Windows key. And glance up to the space above the touchpad and you’ll find two hardware switches.

Security: Updates, 2017 Linux Security Summit, Software Updates for Embedded Linux and More

  • Security updates for Tuesday
  • The 2017 Linux Security Summit
    The past Thursday and Friday was the 2017 Linux Security Summit, and once again I think it was a great success. A round of thanks to James Morris for leading the effort, the program committee for selecting a solid set of talks (we saw a big increase in submissions this year), the presenters, the attendees, the Linux Foundation, and our sponsor - thank you all! Unfortunately we don't have recordings of the talks, but I've included my notes on each of the presentations below. I've also included links to the slides, but not all of the slides were available at the time of writing; check the LSS 2017 slide archive for updates.
  • Key Considerations for Software Updates for Embedded Linux and IoT
    The Mirai botnet attack that enslaved poorly secured connected embedded devices is yet another tangible example of the importance of security before bringing your embedded devices online. A new strain of Mirai has caused network outages to about a million Deutsche Telekom customers due to poorly secured routers. Many of these embedded devices run a variant of embedded Linux; typically, the distribution size is around 16MB today. Unfortunately, the Linux kernel, although very widely used, is far from immune to critical security vulnerabilities as well. In fact, in a presentation at Linux Security Summit 2016, Kees Cook highlighted two examples of critical security vulnerabilities in the Linux kernel: one being present in kernel versions from 2.6.1 all the way to 3.15, the other from 3.4 to 3.14. He also showed that a myriad of high severity vulnerabilities are continuously being found and addressed—more than 30 in his data set.
