Zipping files on Linux: the many variations and how to use them

Filed under
Linux
HowTos

Some of us have been zipping files on Unix and Linux systems for many decades — to save some disk space and package files together for archiving. Even so, there are some interesting variations on zipping that not all of us have tried. So, in this post, we’re going to look at standard zipping and unzipping as well as some other interesting zipping options.

  • How to Setup DRBD to Replicate Storage on Two CentOS 7 Servers
  • How to Install WebStorm on Debian 9
  • How to install FFmpeg on CentOS 7
  • Facebook AccountKit with Qt/C++ on Android

    Facebook’s AccountKit is an authentication service that can use your email or phone number to login to your services, it doesn’t require that the user has a Facebook account, just a valid email or phone.

    The cool thing about it is that it sends SMS for free, and although sending SMSs is cheap being free of charge is something you might want to look when creating a new App, in fact here in Brazil some big Apps do make use of it.

    So long story short story I wanted to add this to my Qt Android App.

  • NeuroFedora updated: 2019 week 2

    We had our first meeting of the year. The full logs from our meeting are available here on the Fedora mote application. I have pasted the minutes of the meeting at the end for your convenience.

    The meeting was broadly for the team to come together and discuss a few things. We checked on the status of current tasks, and discussed our future steps. We've got to work on our documentation, for example. There's a lot to do, and a lot of cool new things to learn---in science, computing, and community development. If you'd like to get involved, please get in touch.

  • Alibaba Snaps Up data Artisans for €90 million: Open Sources “Blink”

    Streaming analytics market projected to reach $47 billion by 2025

    Alibaba has bought Berlin-based startup Data Artisans for a reported €90 million (£80 million) in a deal that will see the $39 billion (by 2017-2018 revenues) Chinese juggernaut take its in-house Apache Flink code developments open source.

    Data Artisans was founded in 2014 by the creators of data stream processing engine Flink. It won Intel Capital funding for its Series A round in 2016 and appears to have also had Alibaba backing in an unreported Series B.

  • LCZero Chess Engine Performance With OpenCL vs. CUDA + cuDNN vs. FP16 With Tensor Cores

    A Phoronix reader pointed out LCZero (Leela Chess Zero) a few days ago as an interesting chess engine powered by neural networks and supports BLAS, OpenCL, and NVIDIA CUDA+cuDNN back-ends. Particularly with the FP16 cuDNN support, this chess engine can be super fast on NVIDIA's latest Turing GPUs with tensor cores. 

    With LCZero's build process being sane for its different back-ends and the program turning out to be benchmark-friendly and meeting my requirements, it's now available via the Phoronix Test Suite with a simple phoronix-test-suite benchmark lczero (granted, the back-end support may obviously vary depending upon your hardware/driver support) and more details over on OpenBenchmarking.org.

KDE: Usability & Productivity Report From Nate Graham

  • This week in Usability & Productivity, part 54
    This week in KDE’s Usability & Productivity initiative, something big landed: virtual desktop support on Wayland, accompanied by a shiny new user interface for the X11 version too. Eike Hein has been working on this literally for months and I think he deserves a round of applause! It was a truly enormous amount of work, but now we can benefit for years to come.
  • KDE Now Has Virtual Desktop Support On Wayland
    KDE landing virtual desktop support on Wayland this week is certainly quite exciting while also a new UI was added for the X11 virtual desktop support too. Some of the other KDE improvements that landed this week and relayed by Nate Graham include the digital clock widget now allowing adjustments to the date formatting, the KDE Information Center's USB devices section will now actually display all USB devices, wallpaper chooser view improvements, and various other improvements.
