fh973on Build distributed RocksDB with OmniPaxos in 8 minutes

What are the advantages of doing database replication this way with a replicated state machine (?) vs. fault-tolerant leader election and primary-backup replication?

Use a distributed file system or object store with what you need, like Quobyte or Ceph.

It may have flash. Parts of the AGPS data are valid for weeks and may help the cold start.

fh973on FAA seeks public input on drone operations

Not sure sure you're trolling, but balloons are big, bright colors and are not even moving relative to wind (which is the relevant frame of reference). I can't think of anything less dangerous in the air.

fh973on Tape Storage Trundles On, Increases Yearly Volume to 128 Exabytes

Tapes are not strictly sequential, they are also a 2D medium, admittedly with one sequential dimension:

fh973on Tape Storage Trundles On, Increases Yearly Volume to 128 Exabytes

As IBM seems to be the last man standing in the tape storage market, the TCO price of tape is not a market price against competitors, but against HDD storage.

The TCO of tape only makes sense at scale, and is much harder to assess than HDDs, as tape cost includes media, drives and libraries, each of which have different life times. Tape libraries can be used across many tape generations.

Congratulations, well deserved!

Also in memoriam Jochen Liedtke [0], who started the L4 kernel project and rekindled research in microkernels by showing that they don't have to be slow ('slow' as in Mach's long IPC latencies).

Actually no. The fact that to the left was a restricted airspace (that the pilot must be aware of) disambiguates the instructions already. Obviously the pilot did not do their flight preparation, was it includes being familiar with any airspace restrictions.

I think it's hard to export the SV software engineering culture to foreign offices. You have at most a few people to seed it, but then it's overrun by people with totally different backgrounds that have no idea what it's about.
