Comment however the satellite orbits are constant (enough) (Score 1) 84

the path length is not constant, however the latency delta is a function of the orbits of the satellites currently carrying the user signal, and should be easy to calculate.

i presume this would depend on starlink being smart enough make and report the calculations.

Comment Re:It's an ingrediant in US Gas (Score 2) 190

it's not just the thread, the articles only hint at the efficiency, however please understand that anything which allows us to capture electricity and store it efficiently is valuable.

batteries are not at all efficient, they are heavy and bulky and have limited life.

if we can turn electricity into a fuel we can burn is way more efficient in terms of weight and bulk and storage life.

these factors tend to mitigate how inefficient the actual conversion process might be.

this process appears to consume no rare materials, and the catalysts are reported to have good working life, it also runs at low temperatures and pressures, so can be pulsed efficiently, in response to supply...

it all looks quite good, to me.

Comment bunch of jaded satirists, you lot.. (Score 1) 190

mark my words - this work, and similar, contains the answer.

meantime i'm wondering if the old slashdot audience have moved on, somewhere more sensible.

this place is like the slow class, now, full of people trying to be funny, and it's exhausting to read.

which might explain why i didn't, and went and read the article, instead.

if there are any intelligent commenters in here, i'm sorry i missed you.

Submission + - Google to build undersea network cable connecting the US, UK and Spain (bbc.com)

rewindustry writes: Google has announced plans to build a new undersea network cable connecting the US, UK and Spain.

The tech giant says it is incorporating new technology into the cable, which it claims is a significant upgrade to older existing lines.

The project is expected to be completed by 2022.

Comment this is not science (Score 1) 38

"Tiny bubbles of gas trapped inside that meteorite have exactly the same composition as the atmosphere of Mars, so we know our rock came from there."

this is not a scientist talking, this is hardly more than wishful thinking.

more accurately stated, the odds are better than none that "our" rock came from Mars.

Comment all the comments are silly jokes (Score 1) 34

is the slashverse full of giddy children, these days?

materials science observes and classifies solids by the forms they break into.

these forms are myriad.

according to the slash (have not read the article) the authors results are based on two computer simulations and one trip to a single dolomite mountain.

this is not research, this is rubbish - throw the bums out, they are wasting resources.

Google's Top Search Result? It's Google (themarkup.org) 55

In Google's early years, users would type in a query and get back a page of 10 "blue links" that led to different websites. "We want to get you out of Google and to the right place as fast as possible," co-founder Larry Page said in 2004. Today, Google often considers that "right place" to be Google, an investigation by The Markup has found. From the report: We examined more than 15,000 recent popular queries and found that Google devoted 41 percent of the first page of search results on mobile devices to its own properties and what it calls "direct answers," which are populated with information copied from other sources, sometimes without their knowledge or consent. When we examined the top 15 percent of the page, the equivalent of the first screen on an iPhone X, that figure jumped to 63 percent. For one in five searches in our sample, links to external websites did not appear on the first screen at all. A trending search in our data for "myocardial infarction" shows how Google has piled up its products at the top. It returned:
Google's dictionary definition.
A "people also ask" box that expanded to answer related questions without leaving the search results page.
A "knowledge panel," which is an abridged encyclopedia entry with various links.
And a "related conditions" carousel leading to various new Google searches for other diseases.
All of these appeared before search results by WebMD, Harvard University, and Medscape. In fact, a user would have to scroll nearly halfway down the page -- about 42 percent -- before reaching the first "organic" result in that search.

Comment and our global conscience gains vision (Score 1) 66

the use of optics to calculate vector maths, etc, has massive potential.

as the article concludes, a lot of our data is already from optical sources.

this is not binary data, and will never be completely rendered as such, there is always a loss, an approximation, and the output data is massive, and takes enormous work and resources to compress, store and transmit.

to date our global conscience, what google wants to call our world brain, our connected network, has been fumbling in the dark, representing sight by numbers, and appreciating it by arduous calculation, like a blind person, unable to actually see the images, only able to describe them.

now, given the ability to compute optically, directly, our global network will have sight.

this will be interesting, very.
