NASA Launching Astrobee Robots to Space Station

https://spectrum.ieee.org/automaton/robotics/space-robots/na...

Astrobees are the robots that will soon float around the ISS. Each Astrobee is a cube with 30 cm (12 inch) side and is equipped with 6 cameras, touchscreen, speaker, microphone, signal lights, laser pointer and a built-in gripper. Among other things the robots will monitor radiation and air quality onboard the space station. The robots are controlled by pushing air through 12 adjustable nozzles and their software has been developed using ROS .
In my experience at least with lawyers (don't know any judges), I wouldn't trust them with that sort of thing any more than anyone else. They're hyper concerned with convincing arguments, to the point where they often fail to make the distinction between something that is actually true and something that seems like it should be true. They know plenty about law and the sort of reasoning that makes the interpretation of law consistent. But it doesn't seem like they're in a position to understand scientific evidence better than your average joe. Like, programmers and folks on hacker news are great at computers and sometimes math and engineering. But I'm not sure I want hacker news giving me dating advice or gardening advice. That's not really in their wheelhouse. Unless you had specialty judges who only did something like determine the validity of certain kinds of evidence who didn't have to have the same skill set as other judges, I don't see it as being much of an improvement.
And still does.
You must be joking. Their product search is terrible - hundreds of irrelevant results which are impossible to filter in any reasonable way.

I am an almost entirely self-taught jazz musician. I learned to read notation begrudgingly, assuming it to be an archaic hurdle put in place by snobbish classical musicians. My view of classical musicians has not changed, but my view of notation has.

A lot of people think that programming languages are a similar archaic hurdle and set out to build a visual programming environment that will be easy for beginners to use. Somewhere along that journey, they invariably realise that a) syntax is one of the easiest parts of programming, b) there is no good visual metaphor for recursion and c) the Deutsch limit is a cruel master. You can do simple scripting with a box and arrow diagram, you can teach kids to blink an LED, but you can't write a compiler.

The advantages of stave notation (and the disadvantages of alternative systems) are non-obvious, but they are very real. Critiques of notation usually sound like "command lines are stupid, everything should be a GUI" - they're not wrong per se, they just miss the point.
Up until now (see rdsetroot), OpenBSD never had an equivalent to mdsetroot (NetBSD)?
> The beneficiary of the check is the bank, but they tell you it is done for your own security.

To clarify, this is about a liability shift. By putting customers through payer authentication, liability for fraud shifts to either the merchant or the customer, depending on the flow, rather than the bank. This is why the bank is the beneficiary.
Same. The edited version loses the author's voice - which is what good editing is not supposed to. And the aside about same-sex romance authors goes from a personal anecdote to a general statement. Personal anecdotes are more entertaining.

See Figure 2, Gas Permeability of Mylar vs. Temperature

Helium permeates Mylar significantly faster than hydrogen over the full temperature range tested. It looks like the helium permeation rate is nearly double that of hydrogen near room temperature. Surprising! I would have guessed that lighter gases permeate faster. Note on the same figure that oxygen permeates faster than nitrogen even though it's heavier.

There is more tabular data here:

https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/196900...

It confirms the same trend. Helium permeates Mylar faster than hydrogen.

Additive meter just shows where the concept of "time signature" breaks down The pulse of the music is not apparent from the notation. So it doesn't even fully explain Western music, much less non-Western music. (That said, while 7/4 exists in the repertoire, it's exceedingly rare - European music tends to be very simple rhythmically, compared to Indian, Arabic, or most African music.)
I think you are right to some extent.

Democracy as a shallow concept is mainly good at handling despots. The 0.1% can't get much power even if their influence is relatively large because the other 99.9% is against their one sided interests. But if you manage to convince 10% of something they could potentially get 51% of the influence, especially locally, at which point you have a big problem. Now 10% of the people can decide what to do against the interests of 90% of the people. A two party system makes this even worse in the US.

That said, it can be solved within democracy. It isn't the first nor the last challenge facing society, especially a changing one. I think we need to realize that we are in a second industrial revolution, with information this time.

"Christians precipitated the destruction of the pagan culture, which was the only culture shared by all people in Europe."

? 'Pagan culture' is not some unified set of cultural norms. Rather, it's a broad category of possibly totally unrelated activities. Some of them codified via Rome (but those were adapted to Christianity) and then other, local ones.

The Christians in 300 CE were the most organized group on the continent, which was part of the reason the Emperor adopted Christianity.

An organized group of busy bodies might cause the decline of some thing (i.e. paganism) but certainly not the decline of the written word, education, governance etc. just the opposite.

One might argue that with the failure of Imperial Order, and the onset of tribal wars, it was the monks that carried most of the flame of civilization, which eventually led to the renewal of civil order and the reasonable ability to establish something approach civility.

Which is maybe close to the classical 'dark ages' narrative. Now of course maybe it was not as dark as we thought, but we certainly don't have a lot leftover from that time. Hence the historical narrative.
Sure there are good apples. It’s the system we ought to concern ourselves with. Does the system incentivize the shovel-leaners?

This paper is pretty excellent. In particular I sort of love that they included a "Hypothesis" section that laid out what their expectations about security were.

They set out to confirm a hunch that despite reducing attack surface by using stripped-down kernels, unikernel applications would be less secure than containerized applications because the unikernels would have relatively primitive runtime security, compared to Linux container systems which inherit two decades of countermeasure work.

They tested IncludeOS and Rumprun and found both to have approximately 1998-levels of runtime hardening. IncludeOS in particular was a steaming crater at the end; a stack overflow on IncludeOS could write directly into the (writeable!) program text, and the NULL page was writeable and executable.

Haha my comment was originally drafted to accuse the parent comment of the same. As I read the article, its concerned with error (e.g. misclassification of cancer) but the parent comment translated this to mean the social bias.
Yes, but what happened in 2008, and caused the crisis referred to by rapsey, was that housing lost a large fraction of its value. It was not a drop in construction, financing etc that tanked the economy; it was the loss of value, which left a giant hole in balance sheets.

The apples-to-oranges comparison was introduced by rapsey, I merely provided the numbers.

You must live in a high density urban area. In suburban Ohio where I’m from people can and do buy pickup trucks for status reasons. Those bigger trucks can cost up to $70,000.

A F-150 was sold in 2018 every 35 seconds. They sold 450,000 of the things in 2018, and that’s not even counting any other truck made by Ford or anyone else. I guarantee you a huge percentage of those do nothing but commute.
Facebook hires some of the top software developers and engineers on the planet, if not leaking plaintext passwords is too high of an expectation for them then nothing that isn't public knowledge should ever be put into any computer system. As a profession we should demand our peers do better than this.
It did, it was just not installed by default, it was originally only available at build-time (as eflrdsetroot).

This just promoted it to a regular base utility, and also it was rewritten using libelf(3).

> How much of Tesla's losses are caused by spending money on continuous expansion of manufacturing capacity?

That's called Capital Expenditure. Page 9: https://ir.tesla.com/static-files/b2218d34-fbee-4f1f-ac95-05...

Q1 2019 had a CapEx of $279 Million. In contrast, Q1 2018 was a CapEx of $655 Million (Q1 2018 was during the Gigafactory "ramp up", so they needed to pay for all of the equipment as the factory became operational)

> I've always thought that FUD regarding Tesla is mostly caused by short-sightedness and that they're not profitable because every dollar they make is going towards expansion.

They posted an operating loss of $500 Million in Q1 2019.

* Revenues -- The price of the car. If someone pays $40,000 for a car, that is +$40,000 in Revenue.

* Cost of Revenue -- The price Tesla paid to make a car. Based on Q1 numbers, Tesla paid $32,561 to make a $40,000 sale.

* Operating Expenses -- The cost of service centers, sales staff, administration, research and development, etc. etc. These don't "scale" with the car like "cost of revenue" does. Tesla spent $1 Billion on OpEx in Q1 2019.

* Operating Profit/Loss: Revenues - Cost of Revenues - OpEx. Tesla lost $500 Million at this point.

* Net Loss: Don't forget the interest rate on loans: 157 Million for the quarter. Net Loss: $667 Million.

All in all a $667 Million loss.

---------

* CapEx -- The cost of expanding the business. Building factories, buying new equipment, etc. etc. $279 Million. "Equipment" still has value when you buy it, so this doesn't count as a cost. Theoretically, if the company were to go bankrupt, it would sell the equipment to other companies and make some amount back. So CapEx counts as an 'investment', not as a cost.

* Loans and stuff -- Various loans were paid off this past quarter. $653 Million total.

* Total cash flow out: -$1.593 Billion. (Tesla's cash dropped from $4.2 Billion to $2.6 Billion this past quarter)

All in all, you can figure it all out on page 7, 8, 9, and 10 of the paper: https://ir.tesla.com/static-files/b2218d34-fbee-4f1f-ac95-05...
The enterprise license requirement for Caddy 1.0 is for using their build infrastructure, not for using the build. The banner was something that could trivially be removed (if it was even present this way) by compiling from source.

FOSS doesn't meant the company doesn't deserve to seek a business model. In fact, I applaud Caddy's approach towards finding a business model without interfering with the FOSS nature of the project itself. If you want to avoid Caddy's business model entirely, just build from source.
The email contacts feature already existed but was disabled in the past, so it just needed to be a Boolean switch. Like anyone who uses Messenger, I can believe they could introduce a regression and never fix it.
When Souls Shudder: A Brief History of Disgust and the Law
I'm not sure anyone claims that, but obviously saying "Similar punishment for similar transgressions" means that different transgressions need not have the same punishments.
Interesting discussion, even though some responses are emotionally charged, understandably :-)

IMHO, the key ethical question is, how can a person (the child in question) be made party to a contract in which they have no input?

Is it unreasonable to give them full/veto choice over the matter of contacting genetic parents -- because that is the only place in the story where they have any agency? Donors & receivers have full agency at the point of exchange.

Further, if one is willing to conceptually agree that a child might have needs/rights beyond what parents (either adoptive or biological) might be willing to provide for, then one is necessarily led to seek & consider data on possible harms (emotional or otherwise) to children who do not have the choice to contact their biological parents.

As a structural engineer, I feel like it'd be "obvious" to default to megapascals (MPa) here. Maybe it's less relevant for planes, but if you're in, say, a submarine, then there's a direct relevance of the pressure of the air inside the sub, the pressure of the water outside the sub, and the tensile strength of the hull of the sub—and they're all measured in MPa (or sometimes GPa.)

Funny statement about free expression coming from the guy who donated to California Prop 8.
There might not have been a large-scale public data dump of passwords, but if 20,000[1] employees had access to logs with plaintext passwords, there is no guarantee I could ever accept that zero of them read or used customer passwords for personal purposes.

What's to stop a malicious ex-lover from grabbing a FB password and reading that person's private messages? If FB didn't even know there were passwords in plaintext, they very likely weren't auditing log access as much as was needed.

It's a big company. Just as not everything good that happens can be attributed to Musk, I'm not sure all of those can be attributed to him either?

I'm a second generation American, and acknowledge that I am a legacy of my heritage. However, I do not really define myself as such, as I am more than just the sum product of genes.

My brother was in Czechia on a recent business trip, and between his looks and last name, everyone there assumed he was a local... until he opened his mouth, at least.

If I am asked on a form, I'll typically put decline to answer or other.

However, I also acknowledge that how to reconcile the history of your family with your own identity as an individual is a difficult and personal decision... especially when the law is involved, such as / for example around tribal memberships.
or how overblown those concerns often are, since they are in fact being spouted by the business model that facebook effectively killed: media ads.
I agree. I know a lot of genomics and health and after having my whole genome done, the results were worthless- I knew more than the genetic counsellors and had to explain to them that just randomly googling for SNPs and grabbinbg keywords from the research papers was a terrible idea.

There are a few very well done genetic tests for a limited number of diseases.
That's not a W, though. It's playing to a tie, then forfeiting the rest of the game. Naturally, I would love for this to go to trial. Even if the FTC lost, at least we'd know what the consumer privacy landscape in the US actually looks like.

The title of this post/story, should be "Facebook Expects to be Fined Not More Than $5B by FTC," because a $5B fine would be extremely not-painful; there would be zero deterrent effect from a fine of this size.

Equifax did not violate the terms of a prior FTC settlement agreement in order to avoid punishment for their prior bad behavior. It’s a lot easier to expedite penalties when there is a written settlement that is being violated than original bad acts.

The Equifax matter is far from over, they are being investigated by: 48 state Attorneys General offices, the District of Columbia, the FTC, the CFPB, the SEC, the Department of Justice, other U.S. state regulators, certain Congressional committees of both the Senate and House of Representatives, the Office of the Privacy Commissioner of Canada, and the U.K.’s Financial Conduct Authority.

Not to mention they made a recent SEC filing acknowledging they expect fines from FTC and CFPB.
Perhaps, in this case, the fraction is closer to 1/1 than they care to admit.
US Government targeting Immigration Lawyers, Activists, and Reporters
>It’s like the closest thing to slavery

It is not just like slavery, it _is_ slavery. The 13th amendment explicitly and intentionally allows slavery as a form of punishment.

And at the end of the Civil War, southern states capitalized on this and passed broad laws like the vagrancy act that re-enslaved the recently freed. For example, looking for separated family became criminal vagrancy.

The curiously profitable idea that forced labor is somehow morally beneficial to its victim predates the Civil War and unfortunately clearly continues today.

We're all people of varying skills, I would never assume an innate high bar for any activity a human does - only by requiring the bar be maintained at a level and regularly checking and enforcing that requirement can we be reasonably sure it is - and this isn't just `echo $password` the way these passwords got into the log file is (from what I've been able to discern) pretty obscure and round about - Facebook is absolutely responsible and needs to be held to account, but the mistake is understandable.
That’s fair - at the extreme end it is probably harder to understand.

Abuses are just that. If a corrupt person is using the law corruptly in order to achieve something illegal, and getting away with it, that is something we should root out. Including your hypothetical racket.

Creating laws to prevent the population from being abused and manipulated via big data is somewhat orthogonal to that, as it would be a separate set of laws. we can’t not do something just because it might be abused by those implementing it. We have to include reasonable limits to the powers we grant.

We don’t do away with all rule of law because it is occasionally abused, we prosecute the abusers under said laws and create new laws when loopholes are inevitably found.
