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

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

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

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.
