Why Teams is a key product despite its frustrations - and yes, a Linux client is on the way. Analysis Microsoft continues to plug Teams as the "fastest growing application" in the company's history, though it is not sold separately, only as a feature of Office 365 (there is also a free version). At the same time, there are major feature gaps that are only now being plugged, and it is not easy to manage. What is the attraction?…

What makes a lantern a lantern are the parts that are missing: windows cut from the structure so that light can escape. While it[he]#039[/he]s impractical for lighting, a lantern with windows in spooky shapes and lurking silhouettes can be atmospheric and a lot of fun to create.

Manjaro Linux 18.1.0 Juhraya Cinnamon - Spicy but sweet

You know how the popular saying goes. When it rains ... people drive slowly just to annoy you. But as it happens, I received a bunch of emails from people asking me two things: 1) Why have I not recently done any more Cinnamon reviews (other than Mint)? 2) When am I going to review the latest version of Manjaro 18.1 Juhraya? The answer to these question is: yes. At the same time! I decided to try Manjaro Cinnamon, not something I've done before, so it should be an interesting, refreshing and hopefully worthwhile exercise. The test box will be the same one I used for the Illyria Xfce test, so we can compare things in earnest - and accurately. This is an eight-book mixed Windows & Linux box, and it comes with UEFI, Intel graphics, 16 sweet partitions, and another instance of Manjaro that we won't touch in this review. Begin to start.

Pacman 5.2 Release

We have a clear winner. Although I’m sure that at least half of those are in responses to bugs he created! He claims it is a much smaller proportion… And a new contributor in third. What has changed in this release? Nothing super exciting as far as I’m concerned, but check out the detailed list here. We have completely removed support for delta packages. This was a massively underused feature, usually made updates slower for a slight saving on bandwidth, and had a massive security hole. Essentially, a malicious package database in combination with delta packages could run arbitrary commands on your system. This would be less of an issue if a certain Linux distro signed their package databases… Anyway, on balance I judged it better to remove this feature altogether. We may come back to this in the future with a different implementation, but I would not expect that any time soon. Note a similar vulnerability was found with using XferCommand to download packages, but we plugged that hole instead of removing it! Read more
