3 ways to trick out your terminal emulator

LXer - Wed, 2017-08-23 10:49
The command line is one of the most well-loved parts of a Linux distribution. Maybe not just because of what you can do with it, but how you can use it. Terminal windows are notorious for customization, and there’s several... Continue Reading →

Canonical Put Spotlight on Snap Apps for Ubuntu 17.10

LXer - Wed, 2017-08-23 09:23
The latest update to the GNOME Software (aka Ubuntu Software) in Ubuntu 17.10 brings two key changes to the desktop, both of which make Snap apps appear as first-class citizens and everything else, well, not.

Zorin OS 12.1 Lite, the Xfce one

 DarkDuck: Zorin OS has always been famous for its design, specifically made for Linux newcomers, thus made to resemble the Windows interface.

I fell for it again

Reddit - Wed, 2017-08-23 08:16

I installed Linux (CentOS 7) and it trashed my ability to boot into Windows.

It goes the same way always, spend 2 weeks on and off trying to fix it, try every answer on google (nothing helps), reboot about 500 times, and then ask myself why I keep using linux.

I've rebuilt the grub menu about 1000 times using all kinds of directions. Nothing helps. Honestly, this is pathetic. I have real things to do with my time not chase down these lazy bugs. This shit should never leave beta.

Why in gods name, in 2017, is linux STILL trashing Windows?

I guess Ill spend another handful of hours trying to fix something that should take 5min max.

ps I've used about 10+ distros since 1998 so I don't think Im having this problem cuz Im new.

btw, Centos7 is amazing.

Linux expr command tutorial for beginners (with examples)

LXer - Wed, 2017-08-23 07:57
Sometimes, while working on the command line (especially when dealing with a shell script), you may find yourself in a situation where you have to perform actions like searching for a substring in a string, finding its index, as well as other things like performing comparisons and arithmetic operations. For those who aren't in the know, there exists a command line utility - dubbed expr - that lets you do all this.

LFTP bash script help.

Reddit - Wed, 2017-08-23 07:00

Hi all,

Relatively new to the world of bash scripts. I'm attempting to LFTP to a server I own, ls a dir and then wait for my command. The next logical command would be to 'queue mirror' or 'queue pget'.

I can get LFTP to call, connect and list the dir contents, but then my script ends and I'm returned to my user. Any advice/assistance would be much appreciated.

Here's my script:

#/bin/bash lftp -p <port> -u <user>,<pw> <ip> <<EOF cd <dir> && lcd <dir> && cls -tr -h -s --date

Thanks.

Gentoo-Based Chrome OS for Work, Gentoo Sources Change

TuxMachines - Wed, 2017-08-23 06:38
  • Introducing Chrome Enterprise

    Since we launched Chrome OS in 2009, our goal has been to build the simplest, fastest, and most secure operating system possible. And we’ve been inspired by all the ways we’ve seen businesses embrace Chrome, from Chromebooks in the office, to shared Chrome devices in the field, to signage and kiosks for customer engagement in retail. But with so many different business needs—not to mention so many different devices—companies have also told us they want a single, cost-effective solution that gives them the flexibility and control to keep their employees connected. That’s why today we’re announcing Chrome Enterprise.

  • Google Rolls Out Chrome Enterprise: Chrome OS For Work

    Google has today announced Chrome Enterprise as a subscription service to take Chrome OS and Chromebooks into more work environments.

    Chrome Enterprise makes Chrome OS more friendly for professional work environments and lets IT/administrators manage Chrome extensions, printers, handle operating system updates, and provides other features like single sign-on support and more. Chrome Enterprise costs $50 USD per device per year and includes 24/7 enterprise support.

  • Switch to Gentoo sources

    You've might already read it on the Gentoo news site, the Hardened Linux kernel sources are removed from the tree due to the grsecurity change where the grsecurity Linux kernel patches are no longer provided for free. The decision was made due to supportability and maintainability reasons.

    That doesn't mean that users who want to stick with the grsecurity related hardening features are left alone. Agostino Sarubbo has started providing sys-kernel/grsecurity-sources for the users who want to stick with it, as it is based on minipli's unofficial patchset. I seriously hope that the patchset will continue to be maintained and, who knows, even evolve further.

    Personally though, I'm switching to the Gentoo sources, and stick with SELinux as one of the protection measures. And with that, I might even start using my NVidia graphics card a bit more, as that one hasn't been touched in several years (I have an Optimus-capable setup with both an Intel integrated graphics card and an NVidia one, but all attempts to use nouveau for the one game I like to play - minecraft - didn't work out that well).

Programming: Java EE, Developer Skills, modulemd, QtWebKit, GnuTLS, React.js Licence

TuxMachines - Wed, 2017-08-23 06:36
  • Opening Up Java EE

    We continue to make great progress on Java EE 8. Specifications are nearly complete, and we expect to deliver the reference implementation this summer. As we approach the delivery of Java EE 8 and the JavaOne 2017 conference, we believe there is an opportunity to rethink how Java EE is developed in order to make it more agile and responsive to changing industry and technology demands.

  • Trending Developer Skills, Based on my Analysis of “Ask HN: Who’s Hiring?”

    For people learning to code and for experienced software developers alike, change is constant. There is always something new to learn. This includes programming languages, web frameworks, DevOps automation, mobile devices, front-end and back-end development, SQL and NoSQL databases, and so on.

  • modulemd 1.3.0

    I almost forgot! Last week I released modulemd-1.3.0, the module metadata format specification and its reference Python implementation.

    This release defines just three new fields but all of them are pretty important.

  • QtWebKit on FreeBSD

    Over at lwn.net, there is an article on the coming WebKitGTK apocalypse. Michael Catanzaro has pointed out the effects of WebKit’s stalled development processes before, in 2016.

    So here’s the state of WebKit on FreeBSD, from the KDE-FreeBSD perspective (and a little bit about the GTK ports, too).

  • GnuTLS 3.6.0 released

    We are proud to announce a new GnuTLS release: Version 3.6.0.

    GnuTLS is a modern C library that implements the standard network security protocol Transport Layer Security (TLS), for use by network applications. GnuTLS is developed for GNU/Linux, but works on many Unix-like systems as well as Windows.

    The GnuTLS library is distributed under the terms of the GNU Lesser General Public License version 2 (or later).

  • Apache Foundation and Facebook in Standoff Over React.js License

    Here's a story that has the two things that open source advocates like to fight about discuss most: licenses and software patents. It started on July 15 when the Apache Foundation's legal affairs director, Chris Mattmann, made a comment to a thread on a discussion board that began two months discussing a little quirk that had been found in the wording of Facebook's open source BSD-plus-Patents license.

  • Want to be a Software Industry Influencer? Get Involved in Open Source

    SD Times recently recognized The Linux Foundation among the top innovators and leaders in software development in its annual SD Times 100 list.

    The LF was honored to be named a top Influencer, along with ten other industry heavyweights including Apple, Facebook, GitHub, Google, IBM, Intel, Microsoft, Netflix, Red Hat, and Slack.

    Does this list look familiar? It should. Each of the companies on the influencers list makes significant contributions to the open source community (bonus points for those who know that most are also members of The Linux Foundation).

    Open source has long been a de facto standard for development and the companies on the influencers list pioneered this approach with their own products and services. At the same time, they have led the IT revolution in massively scalable cloud computing, AI, social networking, and many other innovations, and continue to do so. This is not a coincidence.

  • Open Source For Business: Companies Can Turn To Open Source

    For organizations of any size, there come a point in building out an IT architecture where one has to decide to trust the closed, commercial systems provided by vendors or the open source community that relies on code amassed from people all over the world.

    The latter is a concept that can create hang ups for some—the idea of open anything maybe give a business owner pause and people have raised security concerns about the option for years. But organizations of any size can embrace open source and, in most cases, improve daily operations and become more secure as a result.

  • SQLite: The Universal SQL Database Engine

    Today’s quiz is: What’s the most popular database of all? MySQL? Nope. Oracle Database? Nah. Microsoft SQL Server? Try again. IBM DB/2? Wrong. Arguably the most popular database of all is SQLite.

    Never even heard of it? Find that hard to believe? SQLite’s inside every smartphone, macOS and Windows; and the Chrome, Firefox, and Opera web browser. The reason you haven’t heard of it is because it’s hidden inside the code of numerous operating systems and programs. There, the SQLite C library provides database services for applications.

    This public-domain — not open-source — software is not a database server. Instead, embedded within programs, it provides standard SQL-92 database management server (DBMS) servers without the server part.

  • Cloudera: Unpacking One Of 2017's Most Exciting IPOs

    Hadoop is an open-source project (meaning anyone can download and contribute to the source code at anytime, for free). But Cloudera essentially offers a vastly "upgraded" enterprise-ready version of the product.

Graphics: Radeon, NVIDIA, and Nouveau

TuxMachines - Wed, 2017-08-23 06:26
  • Radeon GPU Profiler 1.0.2 Released With Vega Support

    A new release is available for the Radeon GPU Profiler, AMD/GPUOpen's new low-level optimization tool for game/application developers.

    The Radeon GPU Profiler paired with AMDGPU-PRO on Linux allows for gaining low-level insights into the hardware's performance/behavior for a developer's workloads with Vulkan (or DirectX 12 on Windows). Radeon GPU Profiler tries to make Vulkan profiling quick and painless.

  • NVIDIA 384.69 Linux Driver Released With A Few Fixes

    NVIDIA today released the 384.69 Linux driver as their latest release in the 384 "long-lived" series.

    This is just a maintenance update to the 384 Linux driver and includes Quadro P4000 Max-Q support, an intermittent hang fix with Vulkan when using VK_KHR_display, disabling G-SYNC for desktop environments using libmutter-0.so, a update for the NVIDIA installer around SELinux, and removing support for checking for driver packages in the nvidia-installer.

  • Nouveau's Meager Changes Queued Up In DRM-Next For Linux 4.14

    The changes for the Nouveau open-source NVIDIA driver are now queued in the DRM-Next tree as new material for Linux 4.14.

    The Nouveau DRM work for Linux 4.14 isn't very significant at all and in total has just 287 lines of new code / 75 deletions, which is very tiny compared to the code churn seen by the other Direct Rendering Manager drivers.
