Canonical are transitioning some packages from being Deb based to Snap based. The change has started with Chromium in Ubuntu 19.10 and will be backported to earlier supported releases of Ubuntu.
More packages will be transitioned to being only Snap based over time.
There is no debate, it’s a firm plan that will eventually resources in building and testing.

Endeavour OS is attempting to fill the void left by Antergos. I looked at the September 2019 release which comes with their flagship XFCE Desktop.
The distro is easy to install with the Calamares GUI installer. Although it seems like early days with limited choice in terms of available desktops.

Discussing DNS over HTTPS, a new means of hiding what sites you’re looking at by carrying out DNS requests encrypted over HTTPS. DoH is already in Mozilla Firefox version 69 as an optional feature, but will likely be the default for version 70.

Ransomware Hitting Unprepared American Cities and Schools
Every week I read in the news about how yet another American City or School has had to pay criminals to unlock files encrypted with ransomware.
Why is the public sector unable to recover from the attacks… Is it a complete lack of funding in investing in proper backup solutions.

Enterprise users with Symantec Endpoint Protection should not install updates to Windows 7 updates due to incompatibilities with SHA-2 signing.

The term “sophisticated cyber attack” is said after a data breach to excuse a company for not being able to defend against a nation state attack. But in reality they got caught out by some script kiddie. I’m taking a look at some actual Nation state examples, and attackers initially said to be sophisticated but later found to be a simple management failure.

Taking a look at running Linux on a 1999 Pentium 3 computer. Unfortunately this wasn’t a complete success with Tiny Core Linux, as the computer has no Ethernet port and Tiny Core failed to recognise the only USB WiFi dongle I own. Although I was able to get a working GUI desktop.
I will have to revisit this again when I have either obtained a PCI network card or tried a larger Linux distro with more WiFi drivers included.

Gnome defaults to using Wayland, although Xorg is still available.

#Debian is a slow release and long term support #Linux Distribution, which makes it ideal for using on Servers or corporate environments.
