Python's way of executing a command is somewhat of a nightmare. There are many, many ways to do the same thing, and some are safer than others. Some are better for capturing output, while others are better for just executing and gettin

Stan is nats streaming. The clients don't have to be updated since they're forward compatible since jetstream. NATS streaming will be deprecated after jetstream is GA is my understanding. Is there a bug in the library you found?

The expiration time can be unlimited, just like kafka
515.
by shaklee3 6y ago
Yes, jetstream allows setting max messages to 1 in a stream.
516.
by shaklee3 6y ago
> NATS doesn't ever store messages persistently Not true. Both Nats streaming and the upcoming jetstream (core nats) do.

Nvidia shipped the A100 in 2019. I was using one in August.

That's also not true. They do 4x4, 8x8, and 16x16.
519.
by shaklee3 6y ago
This is not true. What is your source?

by shaklee3 6y ago
Why is written in C bad? Lots of great enterprise software is c/c++.
521.
by shaklee3 6y ago
No, 600 is the total. The propagation delay just to and from the satellite is roughly 500ms. The rest is internet latency and queuing delay.

"DaveMosher reports @SpaceX has contracted @ST_World already "a few years ago" to build 1m #Starlink user terminals at $2400/pc, hence current hardware subsidy for beta testers is $1900. Article suggests, SpaceX may be p

by shaklee3 6y ago
Nope. The burden of proof is on those suggesting history is wrong. Phased array doesn't just drop 3x in price overnight. I'm waiting...
524.
by shaklee3 6y ago
Sure! You mean every phased array that's ever been built? I suppose you have the BOM for the starlink terminal that spacex themselves have said is too expensive? I guess the fact that musk is behind it means the cost is magic and you c
525.
by shaklee3 6y ago
No, they are commodity and we know how much they cost. SpaceX hasn't magically solved somehow decreasing the price of components they don't even make. They are paying over $1000 for a terminal.

To the first hop? 600ms is the round-trip latency of geo.
527.
by shaklee3 6y ago
Starlink will have data caps as well. All models show that when loaded with the amount of subscribers they're targeting you will either get very low speeds (no throttling), or they will need to cap/throttle the heavy users. I&#x27

I'm not sure why you keep going down this rabbit hole, but OP was talking about bandwidth, not latency. Bandwidth on current generation satellites is just as high, or higher than Starlink. Satellite does not use TCP over the air. They

by shaklee3 6y ago
Not true. Most modern geo satellites for internet have switching capabilities.
530.
by shaklee3 6y ago
Not sure what your comment on the frequency range is implying. All signals are converted to baseband before processing. Nobody processes signals on the ground at Ku/Ka frequencies.
531.
by shaklee3 6y ago
Again, OP was talking about speeds, not latency. Nobody is going to refute geo has higher latency than Leo.

by shaklee3 6y ago
Satellites are interference limited and power limited. Dbv is not just for broadcasting, despite its name. It's used for pretty much all non-proprietary satellite waveforms.

The response below mine goes into great deal, but yes, it's going to be fpgas, or an FPGA with a management cpu core in there. They had many reqs open for fpga developers early on.
534.
by shaklee3 6y ago
We do know that. We know how much phased array costs, and many experts in that area have said so. Shotwell and musk both have said getting the terminal cost down is their biggest challenge. They wouldn't say that if it was $500.
535.
by shaklee3 6y ago
OP said "where people couldn't get more than 10/2 or so for any price." Your response directly refutes that, so I don't know why you are asking for a source. I didn't say either of those are competitive with a
536.
by shaklee3 6y ago
It is. The antennas are heavily subsidized to get that $500 price point.
537.
by shaklee3 6y ago
They don't use cpus. They use fpgas, and the signal processing is done regardless of whether a user is there.
538.
by shaklee3 6y ago
Satellite typically doesn't use cdma. See dvb-s
539.
by shaklee3 6y ago
Quite the opposite. VCs are subsidizing those $500 terminals that really cost $1000+.

by shaklee3 6y ago
That's not true. Viasat and hughes cover everywy in the USA with speeds faster than that.
