@dalias @gsuberland I just see this as a sign that the company in question doesn't want my business, and take it elsewhere

@gsuberland welcome to the club, you've got on the akamai CDN shit list.

@gsuberland I've hit it on everything from UPS to mouser to delta airlines

@dalias @alwayscurious @grumpybozo the other thing is I'm mostly talking about residential neighborhoods.

Highways and downtown city centers have nonstop car traffic and light leaking out of storefronts and signs etc. cutting down on roadway lighting won't help much.

A quiet street with a bunch of houses that has a light every few houses for no reason? That's probably the only major light source for 100m or more in any direction

@dalias @alwayscurious @grumpybozo the latter is what i want gone. Where we can actually restore darkness

@alwayscurious @dalias @grumpybozo and if the conclusion is that lighting is beneficial in a particular case as little as possible should be used, for as little time as possible, in as few places as possible.

And externalities like disrupted sleep of residents who have to deal with streetlights in front of their houses needs to be considered too

@alwayscurious @dalias @grumpybozo i actually find the opposite especially in wet conditions, streetlights reflecting off wet pavement create glare that makes it difficult to see, while my own headlights reflect harmlessly further down the road not back at me

@ryanc @gsuberland wave solder / solder pot / solder fountain?

@gsuberland Why 24 not 48? For this kind of thing I'd want to go as high as I can and still be SELV

@gsuberland fair, i have 48V supplies all around my lab for various bigger projects but I'm planning to use it for rack-level DC distribution to all my switches etc long term

Welp, I did it. FFT *and waterfall* in real time on 4 Gsps of streaming waveform data.

This is going in the demo bin for sure.

@foone why would you not do this in raw html? I can't think of any alternative that would be less work

@foone shouldn't need any js or anything this is literally what old school html forms do by design

@iliana @dalias @cliffle Working on it, although I'm a long ways from having something Oxide-scale.

LATENTRED is Kintex UltraScale+ based and will have 48x 1G baseT edge ports and two SFP28 uplinks.

The next-generation model, once I finish LATENTRED, will tentatively be Efinix Titanium based. I haven't decided on the exact mix of ports but the upcoming Titanium v2 parts have up to 40x 25G SERDES lanes, so I should be able to do 10x 100G QSFP28 or, hypothetically, 5x 200G QSFP-DD, with one FPGA.

I might consider a multi-FPGA design with a couple of big Titaniums connected by a bunch of transceiver lanes with the rest used as front panel ports, not sure of details yet.

@ftg @ryanc @s0 @f4grx Reminds me of looking at the logic on a SFP host port on a Cisco Catalyst 2970G.

They had an external CDR PLL module that converted the 1.25 Gbps 1000BASE-X signal to a SGMII-style data + recovered clock pair because the switch ASIC couldn't do CDR on its own.

@dalias @mhoye yeah i would love to see a state AG with the spine to take on resi proxy providers

@ryanc not ethernet, just uart over fiber? I think you might have problems at lower baud rates and might have to modify some of the signal conditioning circuitry to e.g. add pullups on the far side of coupling capacitors but it should be pretty straightforward otherwise

If you're ever looking for an Italian restaurant and don't have a phone or map, but do have a gamma spectrometer, just look for 511 keV annihilation lines and follow them to their source. If you find them from multiple restaurants, the weaker line is the one to eat at.

No matter how well they try to clean cooking utensils between making pasta and antipasto, some mixing is unavoidable which creates a distinct gamma signature.

A smaller annihilation peak is a good sign of more thorough cleaning and better general food safety practices.
