Essential System Tools: QDirStat – Excellent Qt-based directory statistics

tuxmachines.org - Sre, 02/20/2019 - 18:22

This is the latest in our series of articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For this article, we’ll look at QDirStat, a graphical application to show what’s devouring your disk space and help you tidy up the disorder. For details of all tools in this series, please check the table at the summary page of this article.

QDirStat is a continuation of the KDirStat utility. QDirStat is based on the latest Qt 5, and doesn’t need any KDE libraries or infrastructure.

If you come from a Windows background you’ve probably tried WinDirStat, a Windows port of KDirStat, the predecessor of QDirStat.

KDE is adding Matrix to its instant messaging infrastructure

tuxmachines.org - Sre, 02/20/2019 - 18:13

KDE has been looking for a better way of chatting and live-sharing information for several years now. IRC has been a good solution for a long time, but it has centralized servers KDE cannot control. It is also insecure and lacks features users have come to expect from more modern IM services. Other alternatives, such as Telegram, Slack and Discord, although feature-rich, are centralized and built around closed-source technologies and offer even less control than IRC. This flies in the face of KDE's principles that require we use and support technologies based on Free software.

However, our search for a better solution has finally come to an end: as of today we are officially using Matrix for collaboration within KDE! Matrix is an open protocol and network for decentralised communication, backed by an open standard and open source reference implementations for servers, clients, client SDKs, bridges, bots and more. It provides all the features you’d expect from a modern chat system: infinite scrollback, file transfer, typing notifications, read receipts, presence, search, push notifications, stickers, VoIP calling and conferencing, etc. It even provides end-to-end encryption (based on Signal’s double ratchet algorithm) for when you want some privacy.

Canonical Is Planning Some Awesome New Content For The Snap Store

tuxmachines.org - Sre, 02/20/2019 - 17:50

There I was, thoughtfully drafting an article titled "3 Things Canonical Can Do To Improve The Snap Ecosystem," when I jumped on the phone with Evan Dandrea, an Engineering Manager who just so happens to be responsible for the Snapcraft ecosystem at Canonical. As it turns out, that headline will need a slight edit. One less number. That's because I've just learned Canonical has some ambitious plans for the future of the Snap Store.

Extensive Benchmarks Looking At AMD Znver1 GCC 9 Performance, EPYC Compiler Tuning

tuxmachines.org - Sre, 02/20/2019 - 17:46

With the GCC 9 compiler due to be officially released as stable in the next month or two, we've been running benchmarks of this near-final state to the GNU Compiler Collection on a diverse range of processors. In recent weeks that has included extensive compiler benchmarks on a dozen x86_64 systems, POWER9 compiler testing on the Talos II, and also the AArch64 compiler performance on recent releases of GCC and LLVM Clang. In this latest installment of our GCC 9 compiler benchmarking is an extensive look at the AMD EPYC Znver1 performance on various releases of the GCC compiler as well as looking at various optimization levels under this new compiler on the Znver1 processor.

[$] Producing an application for both desktop and mobile

LWN.net - Sre, 02/20/2019 - 17:31

These days applications are generally moving away from the desktop and toward the mobile space. But taking a multi-platform desktop application and adding two mobile platforms into the mix is difficult to do, as Dirk Hohndel described in his linux.conf.au 2019 talk. Hohndel maintains the Subsurface dive log application, which has added mobile support over the past few years; he wanted to explain the process that the project went through to support all of those platforms. As the subtitle of the talk, "Developing for multiple platforms without losing your mind", indicates, it is a hard problem to solve sanely.
