sodacleanon AI can code, but it can't build software

This is how I use them- but I also use them to write initial UI's (usually very primitive). Because I've got an issue where the UI has to be perfect, and if I can blame somebody/something other than me I can ignore it until the UI becomes important enough.

Frequently not. It's always handy to know about extra techniques in soldering.

You can also scale this up in a solder oven and remove almost every single component. Used this for reversing a PCB a few times.

Not cheap.

Theres also services like this: https://www.septentrio.com/en/learn-more/insights/gnss-corre... that offer correction information.

I expect starlink to eat that industry shortly. Not sure how they'll make the strategic steps though. Mandatory location data for cell phones to talk with star-link? Wait for whatever satellite septentrio uses to EOL and offer a deal to use star-link instead?

it gets worse- the overseeing professor mentioned here, and in the video, is the author of the paper linked in the description- from 2018. (https://link.springer.com/article/10.1007/s00190-018-1192-5)

Also, PPP-RTK is another keyword.

Melt the solder and thwack the board on something hard? So the board stops but the molten solder doesn't.

Sometimes though you just have to pile on solder and flux because the via is small enough that surface tension and heat dissipation means its never coming out

sodacleanon Power over Ethernet (PoE) basics and beyond

It's 2 or four pairs. So at minimum you have two 26awg (spec is 24awg, and the slim-line cables are labeled "data only") wires- which is not as big a deal as you made it out. Spec comes out to about an amp per pair.

sodacleanon Why does collapsing a bubble with a sound wave produce light?

Unfortunately, no- while atoms fusing has a fixed mass to energy conversion... getting them close enough that they'll fuse takes a lot of energy. The three hurdles to effective fusion are: 1) getting more energy from fusion than was spent making it happen 2) extracting the extra energy 3) (this never gets covered) avoid neutron flux turning the whole thing into radioactive scrap before it can pay for itself and storage.

National ignition facility (NIF) recently got exited about more energy out than they put in. They don't have a plan for #2 or #3- but as a research facility focusing on #1 thats OK.

Numerous tokamak designs try to handle #1 and #2, but handle #3 by putting rails into the reactor for robots to replace and repair things.

I'm very pessimistic about #3- nothing is immune to neutron damage from fusion, it's just engineering it to fail in a way thats useful. And, once the public accepts the problem, produces less nuclear waste than fission.

sodacleanon Power over Ethernet (PoE) basics and beyond

With most day to day things being some form of streaming it really hides how painfully slow gigabit is.

Additionally, it's not difficult to fit 10gigabit worth of data munging in a 10-15watt envelope.

Pulling data off of modern professional cameras is an easy example.

Realtek's latest NIC is 10/100/1000/2.5/5/10, has a <2w envelope and has offloading that works (unlike intel).

Are you agreeing or disagreeing with it being trivial to check if theres fusion?

> However it's quite possible that I'm wrong. Because bubble science keeps on throwing new surprises.

Ultimately that's my assertion. No need for exaggerated/optimistic claims when something interesting turns up about it on a regular basis.

sodacleanon Why does collapsing a bubble with a sound wave produce light?

Sonoluminescence is not power positive. Fusion would be trivial to prove with a neutron detector- so saying "theres debate" is arguably dishonest.

Sonoluminescence is weird and awesome enough as is: cavitation that produces light.

Amazing indeed- since PoE is DC.

Never noticed the 75ohms before- but it'd be 150ohms for passive PoE. (Through one pair and to another, two 75's)

Theres fixes, but passive PoE was a pretty dirty hack- so negotiation got added.

sodacleanon Power over Ethernet (PoE) basics and beyond

Even with passive PoE you're fine as long as everything is A, B, or any mix thereof.

Apparently, some mag-jacks have the center taps for each pair commoned via 75ohms to ground through a capacitor... so I could be wrong.

sodacleanon Power over Ethernet (PoE) basics and beyond

Because of how ethernet works (differential signaling + signal transformers), PoE is effectively a wire at 48v connected to nothing if the device doesn't support it.

The only issue arises if somebody wires a patch cable completely wrong (neither A nor B), and manages to put one leg of passive PoE's +24v pair matched to one leg of the 0v pair. Which, will promptly smoke the signal transformer... assuming short circuit protection doesn't cut power first. This is why we killed passive PoE.
