Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

milliseconds? We are in the nanosecond now. 10-20ns round trip on 10G or 25G card, in a server which is in the next room of NASDAQ servers to minimize transfer time. Doing millions of transactions per second.

When a packet is received on the RX line, decoded byte per byte (yes, at 25GBps), a packet is sent at the same time on the TX line byte per byte, when the RX byte with the price is decoded, the FPGA determine if you should sell/buy and send the TX byte accordingly on the bus. This takes nanoseconds.

I don't actually work in that space, so I was being conservative with my scales, but I figured it'd be something like that. I didn't know they were doing it on FPGAs now though!

It's disgusting to me that we're wasting this kind of computational power, as a species, for generating wealth instead of science.

That's nothing compared to the useless calculations that are powering the shitcoins

aren't they adding delay lines, so everyone has the exact physical cable distance to the stock servers?

For a while they were keeping microwave towers running to facilitate quicker transmissions. But I’m not sure what the current state is.
