SMS is like fax —an old, outdated standard that refuses to go away. Your Cellular Carrier Can See Your SMS Messages With SMS, messages you send are not end-to-end encrypted. Your cellular provider can see the contents of messages you send and receive.

The SysV init system adhered to the Unix philosophy .

It also culled zombies now and then. SysV init did its job well enough, but it didn’t do it too efficiently. It started processes serially, one after the other. There was no parallelism. The design bottle-necked the throughput. This was more or less masked by the speed gains of modern hardware, and it’s not as if booting a Linux computer took … [Read more...] about The Best Linux Distributions Without systemd
