Point being, we've focused vaccination on the most susceptible groups. Vaccinating even 15% of the total population means we've probably vaccinated ~90% of people aged 75+ (with that number being limited by health conditions that

Current Israeli death rates are with some social distancing measures, but nowhere near lockdown. They're having concerts and (vaccinated-people-only) indoor dining.

"Reboot to initialize" is ugly as hell and very brittle, but it's good enough for most I/O devices like keyboards or headphones. If the kernel is able to properly reinitialize the chip with all of its old association inf

Depends on your definition of "seamless". The base standard's behavior requires a reassociation to the new cell (i.e. AP i.e. BSSID). This introduces a gap in coverage, but for simple setups like the 5-AP one IgorPortola is t

Just because a chip is shitty doesn't mean it's worthless. In practice, Bluetooth is quite interoperable, and reliable enough for many use cases (especially the common, better-tested ones). Breaking compatibility with that ecosyst

Generally, they either: 1. Use low-cost consumer hardware with zero centralized management, and set it up with the same expertise and judgment as your typical residential deployment. 2. Have one admin person with the wherewithal work with w

In actual deployments and support situations I saw at Meraki, connectivity from individual hosts to the internet was usually the most reliable part of the network.

1. Putting the management UI on a local system requires some custom networking setup, and is full of security footguns. 2. Most customers who want this have multi-site setups; in that case, you need paths across the public internet too. Aga

"Cloud-based" is the implementation; the killer feature is the single pane of glass. It's just hard to implement that without putting a bunch of logic in the cloud. Last I worked at Meraki was 2015; I don't remember any

It's a performance thing. With standard 802.11 roaming, you have to reassociate and reauthenticate to the new AP. While this process is underway, you can't pass any traffic. For open networks or simple auth schemes like WPA2 singl

I haven't worked at Meraki since 2015; sorry, can't help you out on that one. I will note that as of 2015, "L3 switching" (i.e. hardware-accelerated IP routing) hardware was expensive as hell. I believe that on the sof
