The metric is a measure of how much of the frequency spectrum a particular modulation format takes up. For example traditional OOK (on-off-keying) has a spectral efficiency of 1bit/s/Hz. In coherent optical communications we ta

Modern optical systems require strong FEC and it’s not uncommon for systems to have pre-FEC BER 1e-3. The FEC gain is high enough to guarantee 1e-12 to 1e-15 post-FEC. Due to FEC it’s not necessary or desirable to have pre-FEC BERs of 1e

I’m not convinced that unifying the tech stacks here really buys much in the way of value for a food delivery business. The real value is the business relationship with the delivery network. A deal that expands the delivery network and add

I don’t see how a government bureaucracy can compete with Azure, AWS, and GCP.

On Mac, I don’t really bother with too much file organization. I have some broad categories but really not more than 1 or 2 folders deep. Stuff that doesn’t fit into those categories just goes in the folder with everything else. Althoug

My mother worked in a funeral home from about 1986 to 1997. I recall when they got their first AIDS victim in 1987. They took the body and I don’t recall my Mother freaking out about it. They realized that sooner or later they were going

I’m not sure about the premise of the article but I do concur that startups have been largely unable to develop new technology and commercialize it until relatively recently. During the 2000’s if you were doing a “hard” tech company, inve

A question, how would the black bar appear in dark mode? It should be set out somehow. Also would be useful if when the black bar appears there’s a link to the person honored.

When we did intensity modulation, there was a time when some cables, particularly in Japan used NZDSF (Non Zero dispersion shifted fiber) type fiber. This was useful when we used OOK (on-off keying) and direct detection. With direct dete

It sounds like you are describing direct detect systems. These are no longer deployed in subsea. Due to the advent of coherent optical transmission and DSP, dispersion is no longer an issue for long distance optical communication. The li

7500 tests per day is a drop in the bucket. There are ~4M people in Georgia. It would take 18 months to test the entire state at that rate.

Maybe my sense of scale is warped but I’m amazed at how little BW the archive uses. Since this data appears to be averaged over a 1 minute window, I wonder what their p99 usage is. The article says they bought a 2nd router. Were they on

People focus on the “plumbing” but the hormones produced by the plumbing are the important things that give us different behavior. I found this article about trans men to be fascinating. The hormones made me more impatient. I had lots of

Sorry but that’s not correct. Have you ever looked at the economics of cloud compute at that scale? You absolutely are paying for a lot of tooling that’s irrelevant to your use case. This is because GCP has to be a general provider. The

Yes, you’re paying for a ton of stuff there that you probably don’t use and then are susceptible to bugs that have nothing to do with your use case. At $5B it would not cost anywhere near that much to replicate. Your infra would be better

A few years ago I was trying to start a company and get it off the ground. We had to make decisions on our tech stack and whether we were going to use AWS and build around their infra. Our business was very data heavy and required transfe

It’s difficult but it’s not that hard and it’s well worth the investment. When I was flirting with founding a company I looked at this trade off and with hiring/overhead etc... it was significantly cheaper to roll our own than it wa

Community spread of zero is not the goal. The goal is to get the transmission rate below 1. A transmission rate of 1 means no average 1 person infects 1 other person. You need a transmission rate below 1 to start reducing the rate of new

This is an excellent point. When I took algebra as an undergraduate I was blown away by the fact that you can choose any axioms and then derive an algebra based on those axioms. I was blown away because prior to that course I just assumed
