Since the end of 2023 or so, I’ve migrated all my workstations from Void Linux to NixOS . Since I was using ZFS with a dedicated boot partition with Void Linux, migration to NixOS was easy: boot the NixOS distro image, load the ZFS pool, create a new ZFS partition, and install ZFS onto that new root. Then comes the problem: I really want to avoid using GRUB2 with ZFS (due to loads of…
RISC-V is a new Instruction Set Architecture originated at UC Berkeley. I’ve always been interested in RISC-V development thanks to its open nature. However, apart from its usage as a MCU (such as Longan Nano or PineCone ) or an FPGA board (such as VexRiscv ), there is not much consumer-oriented hardware capable of running Linux. 1 That was until SiFive announced HiFive Unmatched . 2
I have been building a DVB streaming server with Raspberry Pi 4 in the past couple of weeks. 1 The setup turns out to work pretty well as Raspberry Pi 4 can render 720p in real time with hardware encoding. Streaming MPEG2TS is also possible with Ethernet. However, FFmpeg version shipped with Raspbian does not retain metadata required for maintaining aspect ratio when using OpenMAX hardware…
Many ISPs in Japan have started offering IPv4-over-IPv6 tunnels for their customers in recent years. Most of the IPv4-over-IPv6 tunnel providers in Japan either utilize Dual-Stack Lite (DS-Lite), such as the transix service from mfeed , or Mapping of Address and Port with Encapsulation (MAP-E, RFC 7597), such as JPNE (offered as the v6plus service).
