I re-read the paper in detail. There's a lot more going on than the commentary on this page assumes, with some impressive calculations, but lots of unaccounted-for (and un-invented) elements, and even more unanswered questions.

For example, the author does assume 1gram (2ft diam) shields, but also specifies the necessity of precise angular orientation, and relatively modest location control / steering. This is to be accomplished by an unspecified number of "control satellites" using aimable mirrors and passive radiative pressure, which keeps the discs simple and the weight at 1 gram. Required disc area is ~7x the required total shading area, due to indecent angle and required transparency and spacing. A new gps-like network of "navigation beacons" will also be required to maintain spatial reference. He then says that to track individual disk locations/ orientation, that each disc needs a GPS-like nav receiver, 2 cameras, some processing/ communication ability, and a power supply, presumably solar. But he doesn't account for (or even reconsider) that there will be added weight and cost due to this.

He also doesn't consider the cost of inventing, manufacturing, and deploying the control satellites or the new type of nav beacon network, or even estimate how many of each will be needed. (GPS tech won't work, but if he knows that, he doesn't state it.)

There's other questionable assumptions, like a launch cadence of every 5 minutes for 10 years to leo, and that cost of launch will roughly equal cost of fuel due to the scale.

He also estimates the method of transfer from leo to L1 will require delta-v of 1km/s and assumes it will be solar powered / ion propelled, but leaves it at that, also without scope or cost.

It's interesting, but less convincing than I expected, given all the missing details, and also makes me more convinced that risk assessment, management and mitigation haven't thoughtfully been considered. That said, the shading, geometric layout, and required material properties calculations are quite impressive.

Haha I wonder if this is the comment that I was remembering when I commented above!
Slightly tangent, but in talking about the risks and unintended consequences if such a project, lots of potential issues have been mentioned (which is my bigger overall concern), but given the specs, a new one occurred to me: this design starts to look a lot like what might be required for true singularity type AI.

+/- 16 trillion self-powered, locally communicating "cellular" elements, each with some minimal sensory and processing capability. Add to that the mobility presumed by the author, and the fact that it is literally designed to block the sun, and you've got everything you need for a matrix rewrite...

I think there is still a lot of room for improvement with camera UX. It boggles my mind that all cameras don't have 3 dials as standard - one for iso, one for shutter and one for aperture.
>> consciousness is the only thing we can authoritatively know for sure is real

> this is a commmon goalpost-moving strategy

It's not a goalpost-moving strategy, it's the ultimate one. Your comment exemplifies the difference between science and philosophy. The very idea that "once we know X, we will fully understand humanity" is a common but misguided refrain in science. Science may very well eventually discover "X", but any argument that it will provide widespread meaning or understanding is essentially a philosophical argument.

Silly but fun example as an experiment: scientists create a device that allows you to read and respond to each and every neuron that fires in your head, and also know the downward effects of these firings on your senses, organs, and thoughts. On one hand, that will provide incredible insight into how humans think and process information. On the other, it will fundamentally change what we consider "thinking" and "reacting" to stimuli. Even if scientists created such a gadget, we'd need philosophers to understand how it effects us.
The criticism on Comic Sans consists of two factions:

- Designers who often critizise weird usage of the font (e.g. it is great for a birthday party invitation and bad for a stern warning inholving serious danger)

- people who misread that criticism, hop onto a bandwaggon of their own making and say the font is bad as a whole, because it is not “serious”

Anybody knoes that papyrus font? This had a similar story, with sometimes absurd usages.
It makes you wonder if our brains work as RAM or as a more long-term storage when "rebooted".

I always thought splitting the keyboard and number pad so I could put the mouse in the middle would be a great optimization. Finally did it last year and ended up with tennis elbow. Turns out having my mouse pad a good distance away from the keyboard gives me a chance to stretch out my arm. That tiny bit of extra movement was crucial in not pushing my body over the limit of too much tiny movements resulting in elbow/arm pain.
There are other contributors like using my phone too much in the evenings. But for sure, the keyboard change pushed me over the edge. I now view micro optimizations like this slightly differently. Maybe this keyboard layout would be great! But I sure would pay more attention and watch for negative side effects now.

In the instances I have seen, the news that came out was not expected to come out at the time it did. It was not a scheduled quarterly report or public filing: these were surprise announcements. The market moving up or down before-hand seemed like pretty obvious proof of insider trading.

But isn't sensor sizes still a problem for smartphones. Their tiny sensors will generate noisy images compared with a camera with a full size sensor.
A pedantic note, but what's happened here is that the companies involved have made a commitment to permit you to delete your data from the service. (Which they may or may not properly make good on, I'm not clear on whether they can be legally held to this commitment, e.g. in the US, once it's been made.)

A right to delete would mean something more like that the companies have no choice, e.g. that existing laws force them to delete your data from the service, whether they were willing to commit to offering that option or not.
Well it's condoned by a major world religion and most of the countries that espouse that religion. Good luck changing the opinions of a billion people.
From what I can find the 1DsIII has a dynamic range of 8.8 stops and the iPhone 11 has 10 stops. Have you found measurements otherwise? Single exposure cameras are really no match for computational photography in this area because it gives an effectively infinite dynamic range. You can take the equivalent of a long exposure photo for every shadow on a sunny day.
Canon cameras implemented cloud functions a while back, and I guess it's the same for others. Unfortunately, being just another small feature and not the main function, works like crap (and it seems to be related to the server's bandwidth). Combine a low upload speed with a 30-40MB photo and the capability of getting 10 of these photos per second and you realize it's faster to get the card out and read it on a PC.

This is awesome! I've finished constructing a small repository which runs the following in order to setup a cluster: Bazel, Terraform, Packer, Ansible (which'll run `kubeadm init`), Docker, Kubernetes, Openssl, Jsonnet.

However, it is simply in terms of getting this running. No best practices, no plugins, nothing extra. I think one great thing my little project achieved is that it uses each tool for its appropriate task correctly, without creating hard coupling between tools. I made that repository so others could learn (I pushed to github today under a private repo).

I'm glad a more mature project is out there for this.

> The cost-benefit analysis is then done by private parties, in order to avoid losses and maximize profits.

This is such a theoretical statements that ignores so many realities. Uber wants to enter a new city. The city has an established taxi industry and policies in place to manage pollution, congestion, housing, and new development. What "private parties" are supposed to do the cost-benefit analysis here? Obviously it's in Uber's interest to move in, but what if that increases pollution or the livability of the city to the existing residents? There are no private parties that are in a position to do a credible and representative analysis of the costs and benefits.

I'm an experienced backend engineer who's worked on distributed systems at large scale in both industry and academia, including at AWS and the University of Washington Database Group. I'm mostly language-agnostic but have recently developed an affinity for Rust and would enjoy an opportunity to use it at work. I enjoy mining the academic literature for algorithms and data structures that could be useful in industry: a couple examples are my projects https://github.com/senderista/sorted-vec and https://github.com/senderista/hashtable-benchmarks, which implement and benchmark little-known but promising papers from 1979 (Munro's 2-level rotated array) and 1973 (Knuth's bidirectional linear probing) respectively. Particular academic areas of interest include streaming and sketching algorithms, hash tables, and succinct data structures. I also have considerable experience in DevOps/cloud deployment, including both on AWS and inside AWS itself. Here are docs for an Ansible-based cloud deployment tool I wrote for the University of Washington's Myria distributed OLAP database: http://myria.cs.washington.edu/docs/myria-ec2 (source: https://github.com/uwescience/myria-ec2-ansible/blob/master/...).

I am particularly interested in technically challenging projects which tangibly improve the lives of their users, and in working environments which foster learning, collaboration, empathy, and inclusion. I would appreciate the opportunity to work remotely at least 1-2 days/week.

> "The company is able to do this thanks to a broad terms of service agreement that grants it the perpetual right to use footage shared with it for 'any purpose' it chooses," BuzzFeed wrote.

I always find this odd. Lots of people tell me that they make these TOS to "cover their asses" with the assumption that everyone sues left and right over everything. So do these people realize that that's not exactly what's happening? Do people think of this usage of footage as abuse of the TOS? Because I sure do. I'm not sure how it is really different from copying someone's art and claiming it as your own and (successfully) selling it.
Gee, that's pretty great, but a serious adversary armed with anti-ship missiles is going to use nuclear tipped warheads.

When I say serious, I mean countries with proven nuclear capabilities. Not "limited war" with lesser proxy state dictator adversaries, already bludgeoned by economic sanctions.

And, when I say nuclear tipped warheads, I mean as many as it takes to kill the vessel. Any sane military strategist is going to hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit, and hit the carrier either until it sinks or until everyone onboard and within ten miles is dead.

Even if it takes a solid month of nuclear attacks to starve the crew to death, and melt the deck into slag.

There aren't enough Nimitz class aircraft carriers in the world, NOT to use such tactics.

EDIT: reading the articles, no mention is made of nuclear tipped anti-ship missiles. Probably because it's the article wouldn't be worth writing, if they openly acknowledged that angle, and thus would not generate ad revenue.
I don't understand, what is wrong with extending "=" such that in the example you gave "if(x=3)" it stores 3 in x and then makes the comparison?

More accurately, in Python it would be:

if x = 3: # x is assigned 3 and then tested
do_something_here()

This is different from:

if x == 3: # x is compared to 3
do_something_here()

Very clear difference between the two statements.

What if we want to assign and then compare?

if (x = 3) == y:
do_something_here()

or...

if x = 3; x == y: #Python evaluates left to right...
do_something_here()

In fact, you could...

if x = 3; x == y; x = x + 1: #Python evaluates left to right...
do_something_here()

Not super elegant, but it makes sense. I wouldn't want to write code like that in any language unless it was very well justified.

What if we want to compare and then assign?

if x == y; x = 3: #Python evaluates left to right...
do_something_here()

Side note: Why, oh why, don't we have pre and post increment/decrement (++/--) in Python? Another religious decision.

I guess I am having trouble seeing where this ambiguity might be. What is ambiguous about usage that is currently not legal and is later defined as a new way to make assignments?

In other words, nobody is using it that way today because it doesn't work. Tomorrow we say: From now on, you can make assignments inside of several conditional statements.

What's ambiguous about that?

This isn't foreign at all, is it? I mean, we have been able to do this in C for decades:

int i;
for(i=1; i<=3; i++)
{
printf("%d\n", i);
}

In fact, you can do this:

int i;
for(i=1; i<=3; i=i+1)
{
printf("%d\n", i);
}

That's TWO assignments, not just one. No special operator or syntax. Last I checked no airplanes have crashed, MRI machines stopped working and nobody died because of this. Forgive me but, I just don't see the ambiguity at all. Once you define the extension of functionality the rest is not a problem.

That said, I am eager to learn. I've only been designing hardware and software since about 1982 or so and have programmed in nearly every mainstream language in existence on platforms ranging from embedded to Silicon Graphics supercomputers and even the web. It is quite possible I am confused or just don't understand something. I do have a very pragmatic view of this stuff. By which I mean to say: Simple is usually better and there has to be a very, very good reason to reinvent any wheel.
It took camera companies long enough to catch the digital wave.

I feel Sony are the only company to be looking far enough forward, catering well to the overall industry direction. But even the very best very smallest camera system doesn't fit in your pocket.

I have a bulky DSLR and a mirrorless that I use for bird photography. Most of the time, when not doing that specific task, the camera phone will be good enough if I didn't want to bring my other cameras. And mirrorless cameras are tiny! I can fit a professional quality camera system in a satchel no bigger than my cupped hands, yet the convenience of just keeping my phone on me is impossible to beat.

YMMV, but I would recommend all young children spend as much time barefoot as possible, and in thin flexible shoes the rest of the time (probably not a bad idea for older people as well, but the difference is most extreme for those just learning to move). In San Francisco, my 3-year-old can be barefoot outside most of the year; in places with hotter/colder weather shoes might be necessary during some months.

Anecdotally, being barefoot dramatically improves kids’ rate/quality of learning basic locomotion (balance, stability, agility, speed). The kids I know who are habitually barefoot learn how to walk and run with a graceful and efficient gait in a matter of months and by 1.5 years old are quite mobile, while kids wearing stiff shoes often are still toddling around at age 3.

(I’m sure gross quantity of practice also makes a big difference; some young kids are pushed all around in a stroller/car seat/etc. and spend very little time walking for themselves. The frequently-barefoot kids I know all spend a lot of time outdoors running and climbing around. I am sure even in identical circumstances there will be high variance in young kids’ motor skills. But I bet if we took a random sample of yuppies’ children in a modern suburb and compared them to a random sample of kids from a hunter–gatherer tribe somewhere, the differences would be quite stark.)

It makes plenty of theoretical sense as well: (a) the bottoms of the feet are incredibly dense with nerves, and (b) the feet and lower legs have a huge number of tiny interconnected moving parts. If learning anything is largely a matter of trying a variety of minor adjustments and then gathering as much data about the result as possible, and then throwing it at our personal deep learning neural net machines (a.k.a. brains, specifically the motor cortex), then wearing stiff shoes is a huge handicap, both limiting degrees of possible motion and also obstructing most of the measurement apparatus.
Right now it's free and will be until it's stable. Starting price will be about $25 for 4000 scraping credits, 200k API calls and data storage.

This will likely change as I have more stats and feedback on usage and expenses. But the goal is to offer a price point that's fair and low relative to other options.

It's pretty sad that in 2019, to setup a web app that can properly scale you need to understand and use so many technologies. Developing a scalable website in 2013 was a lot easier than in 2019. Back then PaaS was all the rage (Heroku, Google App Engine, Amazon Elastic Beanstalk). Since then, things have gotten much harder.

I suspect that this development has less to do with technical challenges and more to do with revenue. Cloud providers now provide all of these services, and they make little money getting small folks up and running with something that "just works". The real money is going after enterprise clients that need to tweak every detail and have the resources to devote to all of these technologies.

There have been so many platforms and libraries that have come out over the past 10 years, the industry is more than ready for a period of consolidation.
Yep. Especially on a big screen, where jpegs out of the iPhone (and other brand phones) often look like water colour paintings due to the aggressive denoising that is done, even in bright sunlight where the ISO should be fairly low for the phone.

RAW can be done on phones (I use it on my iPhone), but the result seems to be extremely noisy (but at least you get the detail, which generally gets lost in jpegs from the built-in Camera app).
