Starting Element Messenger Web, Desktop and Phone

Element (formerly Riot.im) is a modern all in one messenger for everyone. Featuring basic chat to file sharing as well as video conferencing, it is designed for users of web, GNU/Linux, Windows, MacOS, plus also Android and iOS. In this regard, Element is a great alternative to WhatsApp or Telegram. This basic tutorial will show you, after introducing it (see here and here), how to use it on Ubuntu and your phone. Let's go!

and can be browsed at the normal kernel.org git web browser:

VirtualBox 6.1.18 Released with Full Support for Linux Kernel 5.10 LTS

VirtualBox 6.0.18 comes about three months after VirtualBox 6.1.16 and it's the first release to introduce full support for the latest and greatest Linux 5.10 LTS kernel series, which is available for both Linux host and guests. Of course, this means that you'll be able to run GNU/Linux distributions powered by the Linux 5.10 LTS kernel as a virtual machine inside VirtualBox, as well as to install VirtualBox on a GNU/Linux system running Linux kernel 5.10 LTS.

  Welcome to the Ubuntu Weekly Newsletter, Issue 666 for the week of January 10 – 16, 2021.

• Simple-Mail Qt library 2.3 released

  SimpleMail is a small Qt library for sending mails, this release makes sure it compiles fine with Qt6, and has some small issues fixed. I thought this would give me a bit of work but was mostly changing CMakeLists.txt and including one header.

• Block spammers/abusive IPs with Pf-badhost in OpenBSD. A 'must have' security tool!

  But how does it do all this? By periodically pulling IP addresses from well-known and well-respected spammer-IPs databases, where bad IP addresses are frequently logged (dangerous IPs reported by internet users) and stored.

  Then adding all collected IP addresses to the PF firewall (as an IP-table) that is already active on your server (hopefully?), and through that way, prevents their access to your server. So sort of works with the PF firewall.

  The blocklists are pulled from quality, trusted sources. The 'Spamhaus', 'Firehol', 'Emerging Threats' and 'Binary Defense' block lists are used as they are popular, regularly updated lists of the internet's most egregious offenders.
