Linux/Unix sysadmins have a weird obsession with server uptime. There is a xkcd comic devoted to this subject where a good sysadmin is an unstoppable force that it stands between the forces of darkness and your cat blog’s servers.
One can tell how long the Linux system has been running using the uptime command or w command or top command. I can get a report of the historical and statistical running time of the system, keeping it between restarts using tuptime tool. Like uptime command but with the more impressive output. Recently I discovered another tool called uptimed that records statistics about a machine’s uptime. Let us see how to get uptime record statistics using uptimed and uprecords on Linux operating system.
Like any good sysadmin, I kept my servers and desktop side up to date and patched all the time. However, recent Java updates have broken my IPMI KVM Java Applets on Dell, IBM, HP, Supermicro and FreeNAS mini servers. You will get an error that read as follows:
Unsigned application requesting unrestricted access to system. The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned.

Purism vendor sells Linux preloaded on the Librem 13 and the Librem 15 laptops. Purism claims to follow a strict belief in users’ rights to privacy, security, and freedom. Untile today Librem bios was not freed. However, the coreboot port for the Librem 13 v1 is 100% done. It means you can have blob free Coreboot running on a full-fledged modern laptop. The laptop comes with Hardware Kill Switches that physically sever the circuit at the hardware level for Wireless & Bluetooth, Camera & Microphone. The specs are as follows:
