HowTo Geek ☛ How to Use QEMU to Boot Another Operating System
That old legacy system is gone, never to be heard from again. Right? But what do you do on the fateful day that someone needs to access data that's trapped in an old legacy application? If modern applications can't read the data, you need to run the legacy system. And that's where system emulation comes in.
The open-source PC emulator QEMU is included by default in most mainline Linux distributions, but you can also download versions of QEMU for other Linux distributions. If you run Windows or macOS, the QEMU website provides packages for those platforms, too. QEMU provides excellent system-level compatibility and support, making it an ideal and lightweight virtual machine environment.

Jeff Geerling ☛ NUT on my Pi, so my servers don't die
Handling power outages is never a top priority... until it's the only priority! And by then it's usually too late! Luckily for me, no data was lost, and my servers all came back up safely.
This week the power company emailed and said they'd be cutting power for maintenance next week, but they don't have an exact time. So it's even more excuse to finally set up NUT on a Pi!
NUT, short for Network UPS Tools, is an open source tool you run on an old Pi or whatever old computer, and it monitors UPSes like the Lowell Power UPS in my main rack. NUT clients, then, can monitor the UPS through the Pi, and safely shut down before the battery is depleted.

Tor ☛ New Release: Rdsys 1.0 | The Tor Project
After years of development, we are officially releasing Rdsys 1.0. Although Rdsys has already been the sole mechanism for distributing bridges since it replaced BridgeDB last October, this version 1.0 milestone officially marks its new status.
We now consider Rdsys stable, but our work is far from finished. We are committed to improving Rdsys and fixing issues as they arise, and to adapting quickly to censors' evolving tactics.
