    Doesn't matter what system you use to install software, you always have to make sure it is from a trusted source. No difference with PPA's. If you know what they are, know how to use them and don't just nilly willy add some random guys PPA, they are fine.

    The system itself is very effective, and it is absolutely crucial to have a single point of install for all packages on a given system that manages the entirety of the dependency tree, not some fragmented system of mixed blobs that may or may not include dependencies patched for security within them, and duplicates dependencies for every package. That is just ridiculous, regardless of what benefits of convenience it implies.

            Ok, cool, but I don't use Twitter, so I didn't see this unfortunately.

                Offtopic – after checking out the link for this PR, I got curious and snooped a bit in the systemd source and now I want to gouge my eyeballs... No wonder systemd is a mess.

                • I've gotten around the rdrand issue in arch. However, my 3900x is only showing 8 cores. Obviously not a ryzen master issue. A bios/cmos reset hasn't helped. Compiling the Linux kernel with my 1700 was faster lol. Anyone have any idea? I don't even know if it's a motherboard or chip issue.

                  • c't expert author Thorsten Leemhuis gently claims having published his findings on RdRand a few hours before this particular(?) article from Michael went live. To me it seems like he (or someone else) was "first" and started a wave of other people with the hardware to their hands jumping on the wagon and giving it much more weight and speed. In those circumstances it sounds hard to have sufficient records at hand for giving the right citation - its surely hard to see the origin of an avalanche whilst the its in full steamy/foggy progress. Now its calming down (except for the now broken PCI 4.0 issue of course ;-) ) and its probably the right time to look a little bit back in time.

                      this is probably one of the best mix of anti-patterns all together
                      Nope, its about the second option you were quoting. i dont like my machine getting blocked either. ;-)
