« devices running these legacy services and software through either carrier or wi-fi connections will no longer reliably function, including for data, phone calls, SMS and 9-1-1 functionality » 911 not working without BlackBerry servers? SMS and calls too? Did they route all of that through their servers?


No, just the handset configuration. See thread from 3 days ago: https://news.ycombinator.com/item?id=29768382


That's correct. The only thing I've noticed so far on BB10 is the "Four Pips" signifying connection to BlackBerry infrastructure vanishing from the top icon bar. Calls, SMS and browser work for now.


The browser had a WAP 2.0 mode, so basically you're likely to be going through your telco's WAP GW/proxy.


How would you get vaccinated twice and get covid twice? I thought most countries allowed to do one shot only if you recovered from covid once.


My country doesn’t make that distinction. There was a year inbetween infections.


1) the screens are really close to your eyes, which is an issue for your eyes to focus on 2) the screens need a high field of view 3) the headset need to provide 6D pose feedback to the computer 4) battery


This is a good summary, to which I shall add heat removal.


5-8 layers but how many weights per layer? I can’t access the article but it says it’s a deep CNN so probably in the order of a few thousands weights per layer.


Up to 256.


Is that 256 weights per-cell per-layer, or 256 in total? Is "how many cells in each layer" a valid question too?


Their pretrained 128-wide net has a total of 9.2 million parameters: https://www.kaggle.com/selfishgene/single-neuron-as-deep-net...


9.2 million parameters per neuron. There an estimated 86 billion neurons in the human brain [0] and 19 billion in the neocortex [1]. That means that, for this strategy to emulate a human brain or neocortex would require 791 quadrillion parameters or 175 quadrillion parameters, respectively. The largest ANN built so far, GPT-3, has 175 billion parameters [2]. We are 6 orders of magnitude from being able to pull it off.

This is assuming there's no weight sharing.

Some of those weights presumably go to reproducing highly-conserved features, like the kinetics of particular ion channels. These are "tied" via the genome, in the sense that there's one KCNC1 gene, but millions of neurons express the ion channel it encodes.

On the other hand, this model is also missing all sorts of other interactions: hormones and other neuromodulators, ephaptic coupling, etc.

It's so complicated I would venture that no one even has a reasonable guesstimate of how close we are, beyond "Not very."


It does, governments can pass laws, big businesses can't. They may buy politicians to pass the laws for them but in the end they can't pass the laws themselves.


Big businesses can pass terms of service, which are functionally identical.


This is ridiculous. I'm not worried about businesses telling me who I can marry, where I can live, or what jobs I can have.


You really should be. Quite a few of the larger companies have been caught conspiring to manipulate wages and workplace mobility for their own gain, in ways that not only hurt every work seeking person in the affected area, but where also flat out illegal.

Then lets not ignore the fact that most countries had to make laws specifically to protect working parents. There are most likely entire warehouses filled with court cases over a business owner realizing that statistically hiring a non married replacement for the recently married employee will be better.

They wont do it out of racism, they wont do it out of religious fervor. However they will do whatever they can to make more money.


You should rwad more science fiction. From the 1960s to 80s-90s, maybe not so much nowadays. Probably because it isn't all that "far out there" any more.


They absolutely would if it made them money.


Which doesn't happen without what large organized body of people to approve or condone it?


All they have to do is convince everyone to do what their phone says, they've already done that with video.


What do you mean? I thought we were able to run programs on these processors already.


"Running programs" is easy. Getting correct answers, not so much. In the case of factoring 15, afaik, nobody has been able to execute Shor's algorithm faithfully -- instead, they simplify the factoring problem using knowledge of the answer. This isn't necessarily about Google -- last I looked, IBM holds the "factorization record" where they were either using a modified Grover's algorithm that incorporated knowledge of the factors. This isn't my area of expertise, but if it was, I'd be hugely embarrassed by the industry.

And then off in the corner, we've got D-Wave, who everybody loves to hate on, doing their own thing with an optimization-based approach to factoring which actually seems to work on (iirc) 10-ish bit semiprimes and zero foreknowledge.


How much have changed since 2007? CPUs are more and more parallel, GPU have taken a big role in computations with specific memory types, etc... ?


Color is tricky because it varies way too much depending on the lighting conditions, right?


French firefighters do this when arriving at a scene. The first messages sent over the radio will say:

- I am... (who you are and where you are)

- I see... (describe what you see in simple non-ambiguous terms)

- I do... (what action you are taking now)

- I ask... (ask for reinforcements if necessary, you may be asked to justify yourself more)


In the demo video, for every basic task it needs some setup by a human (see how they fixed stuff on the stretchable arm for every action other than picking-up something) and all the interesting tasks were teleoperated.

I don't care about teleoperation, for a home robot I want automation.


That reminds me of a book I read as a kid: "My Trip to Alpha I" by Alfred Slote [0].
