Anything new happening on the risc-v side of things? Last I heard there were some micro-itx boards at around rpi4 speed but haven’t heard much since.

RISC-V eats the low-end microcontrollers range alive at the moment with a lot of interesting features (integrated PHYs, etc.) coming from the vendors.

You can already make a MAP network, and any modern client will automatically hop between APs pretty fast, based on which one has the strongest signal. There's a common misconception that devices will cling to one AP while better ones are available, which hasn't been true in many years now from my experience.

Infrastructure side handovers are great for load balancing though, for enterprise networks with very high client density.

> based on which one has the strongest signal.

That's not what you want to have in an enterprise environment.

A roaming decision must be based on the signal level readings from both sides from the infrastructure side.

Everything else is gambling.

> While some draft specifications could be released in 2027, the official Wi-Fi 8 standard is projected to be finalized only in mid-2028. Commercial products that officially support the new standard are not expected to reach the market until late 2028 at the earliest.

I bet companies will release WiFi 8 products even when it's still a draft, just as they did with WiFI 7.

I upgraded my home setup to WiFi 7 a few weeks ago, and after being a WiFi hater for so long, was actually surprised at how much better it was over my previous experiences with WiFi. With MLO clients get 2-3ms latency with 2.5Gbit links, I'm all for WiFi 8 trying to reduce the latency further, I don't need more speed.

They must. Otherwise it cannot be tested within the labs.

And producing chips before a standard is finalized is usually no problem at all: there are gates within the standardization process where the will be no more changes that are relevant for the silicon.

These 802.11n-draft APs were a singular fuckup regarding this.

Wifi-8 will be great. Finally we get seamless controlled handovers between accesspoints that can be controlled from infrastucture side.

With MAP 2.4GHz can serve as long range network that can be filled with High-Rate 5GHz / 6GHz cells. And all of them can be utilized in parallel.

802.11be (Wifi-7) still lacks this.

We need a remote-petting-arm so we can pet the cat'berts over long distance lines.

Also a microphone for receiving feedback.

FYI, most of your comments show up as [dead]. I assume that the ones that didn't (like this one) have been vouched by others.

Not sure if dang see this, but it might be worth asking hn@ycombinator.com otherwise

Interesting. I didn't verify my mail address.

Maybe a flood protection for new accounts.

vpn appears to only work sporadically in china.
lazycatjumping · 3 months ago
All VPNs work without problems with China if you roaming into their network with a foreign (e)SIM.

You will get unfiltered western internet as a tourist.

Recently I was looking for solution to have multiple VPN running at the same time, and without work profile I am limited to one. I want to run two (or more) and be able to tell which app uses no VPN, which routes through vpn1, which routes through vpn1, etc. so far it looks like I need multiple profiles, and that requires root, which Google actively discourages.

Maybe someone knows better alternatives?

lazycatjumping · 3 months ago
I think "WG Tunnel" should be able to do that. You can add multiples profiles and link apps to it.

Wireguard is amazing.

I have an "always on" VPN routing back home. Anything destined for my home network gets routed that way, and there's literally zero battery drain.

I'm not paranoid enough to route everything through VPN though.

lazycatjumping · 3 months ago
For me it's not paranoia.. more like: I have a ton of unused GBit/s left.. so routing a few kBit... MBit/s of mobile data doesn't hurt.
