This is very apt

Seems like Localsend doesn't currently work reliably with Tailscale enabled. This is a bummer. Hope they also allow sending files between clients on the same tailnet, that'll be super neat.

Super cool, lock-in is very real. We are overflowing with Duplo and Lego sets because I just don't want to deal with another system. There are, of course, other models on Thingiverse, Printables, etc., but knowing these are properly designed to fit and work is a huge plus. Cudos to the team!


I think it’s not right to blame teachers, because you cannot control that right? Agree it’s far too hard to find aspirational teachers, but they are naturally in demand and will be snatched up by well paying positions, like private schools. The tool is supposed to help given the current suboptimal teaching practices.


Teachers claiming to be self aware such they don't care and are just there for the benefits can absolutely take some blame

They could quit and free up the slot for someone who does care


It’s human nature really, and we see this in our jobs, instead of using LLMs to learn to do our jobs better, we replace work with automation.

It’s going to be quite hard to motivate students to learn now that they know answering can be automated.


Was about the mention this, -CC has been working perfectly for me


Anyone has done mesh WiFi (ideally triband) using off the shelf parts and Linux?

I have an Orbi AX system which works reliably, but now I want to upgrade the radio to WiFi 7 and that means I need to upgrade all the hardware.

Hoping to move to using off the shelf parts so in the future I can just change the radio (ideally bunch of USB sticks).

I understand this is not strictly just the router. I can (and used to have) a router as separate device, but any mesh WiFi right now that I can find need a pricy router that acts as the coordinator, essentially negates the economic benefits.


That's a bigger can of worms than you might expect. Most consumer WiFi chips only barely support AP mode, and I'm not aware of any that can do multiple bands simultaneously. You'd probably need 4 adapters on the repeater for triband. One to connect upstream, one for each downstream band. Three instances of hostapd all configured with the same SSID and auth for each downstream interface.

Then there's the roaming issue. This is largely what the commercial "mesh" systems try to solve: deciding / helping inform when clients should switch APs. There are many solutions and none of them are without issues, including the commercial ones. Here's a starting point: https://openwrt.org/docs/guide-user/network/wifi/roaming


Super interesting, thanks for sharing


Openwrt guys were cooking up a wifi 7 router I think. Think that’s best bet but Not super close to it though


Related - we have an atomic Seiko wall clock expecting to have the time automatically adjusted by the WWVB LF atomic clock broadcast. Turns out, the signal is very weak where we now live. Manually setting the time on these atomic clocks is a HUGE pain (beware!).

Turns out it's possible to emulate the atomic clock signal quite easily with a Raspberry Pi, or in my case I put together Arduino code that can emulate atomic clock broadcasts from around the world using an ESP32 module using NTP servers: https://github.com/tanvach/clocksync

The history of these atomic clock broadcast signals and their differences in different countries is quite fascinating.


The loopstick antennas used in many inexpensive WWVB receivers have a fairly strong null, so rotating the clock 90 degress can make reception possible.


I would be very careful of transmitting on the same frequency as WWVB. It is very likely illegal.


That’s a very good point but the transmission power is extremely weak and won’t propagate more than 1m.


Quite possibly, however the range is stated in centimetres so practically it’s unlikely to be a concern.


Get out


Supposedly you can do it with a stock smartphone or tablet by using the audio hardware to deliberately generate RF noise that works like a WWVB signal. https://github.com/kangtastic/timestation


You do not have an atomic clock. Seiko does not manufacture “Atomic Clocks” for the $30 shelf in Target. You (and others here) don’t seem to know what an atomic clock is, or how it works, or what it costs!

Your Seiko is a radio clock. It’s probably got a crystal or some other normal timekeeping gadget, and the external WWV signal is decoded to properly set it.

“Atomic Clocks” are marketed to ignorant consumers who blithely use the term when the only external source is a radio station. The Stratum Zero clock may be atomic, but the caesium is not to be found on your nightstand.

No caesium atoms would be found in your Seiko, bro.


Can you please make your substantive points without swipes? This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.

If you know more than someone else, that's great! By all means, share some of what you know, so the rest of us can learn. Just please do it without putdowns.

That distinction is obviously quite apparently from the context. I’m using atomic clock to be consistent with what these radio clocks are marketed as.


Long computing embedded in confusing texts should be sufficient.


Ah, but how do you know it isn't just an LLM solving the problem, to then allow a human to take over? Such as this script, or a chrome plugin.

At that point, I just becomes PoW captcha via an LLM.


There will be a bot/human CAPTCHA economy trading with eachother. This will be how WW4 starts.


It might work for crude actions, but my take is that touch signal is nuanced and won't get transmitted via mechanical linkage well. Love to see it prototyped though.
