Actually the older Iridium satellites were intended to make a flash in the sky. The three aluminium antennas were highly-polished for no other reason than visibility; free publicity. There were some thermal benefits but not significant.

The later blocks of satellites have a different antenna design and do not reflect as much.

A more sigificant astronomical impact of Iridium as a tangent, is that their transmissions on 1612 MHz interefere with radio astronomy observations of hydroxyl. In contrast a single 'disco ball' zipping around LEO for a few months is trivial.
Questions for insiders:

- Does Google have unusually many conservative employees compared to similar tech companies? Or maybe a different attitude towards "diversity" programs?

- Evidence of Google employees doxing one another is evidence of insufficient HR vigilance against assholes. How could it happen?

- Does the "alt-right" have specific reasons to harass Google, compared to other equally hostile and equally important companies?

Apparently some airlines now encourage pilots to do certain tasks that the autopilot can and normally would do from time to time, to avoid this.
For me, rspamd with corresponding exim-acls practically solved that issue since 02/2016. Spam is mostly rejected, otherwise tagged (and filtered with dovecot-sieve downstream into a review-box) or - if borderline - greylisted. Have had no false positives I'm aware of and only 1-2 false negatives per week slip through that cascade.

edit: Although some training (i.e. manually moving spam to IMAP-Junk) was necessary during the first few months.
> Yonatan Zunger, a high-ranking veteran engineer who left Google eight months ago, says the internal culture has become a textbook case of the "paradox of tolerance," the notion that if a society is tolerant without limit, it will be seized upon by the intolerant.

To me, this could all be solved by HR releasing a document on what can and can not be discussed on company time and where the lines are. And if a document exists, enforce it on both sides.

Or you know, not talk about politics in the work place.
I'm inferring from the article the problem is spatial/temporal resolution of the _radar_ currently being used for speed sensing for adaptive cruise control. There are lots of objects that are stationary and near to the road but not in the path of the vehicle (road signs, overhead signs).
You can't blame the human behind the wheel if there's no steering wheel.
Now when did this come out?
I understand that these systems must ignore stationary objects or they'd break all of a sudden at every road sign you encounter, but is there no way to tell a road sign (albeit a big one) from a fire truck that is 20 times bigger than a road sign, and 2-3 times bigger than your car?

No one is going to pay that much attention if your car is on auto-pilot. That's just how people are, no matter what's written on the manual (which no one reads).
As someone who lived in China, I doubt it.

Individual rights and limitations on government power are not taught in Chinese schools nor ingrained in Chinese culture. Politics is not natural part of the Chinese conversational diet in much the same way that bread is not a natural part of their nutritional diet. To the extent that such topics come up it is pragmatic to a fault. It is always in the context of fixing a specific problem in the here and now (Eg there is corruption therefore lets purge the corrupt) and never in the context of a broader political philosophy (Eg how should we structure the civil service to dis-incentivize corruption). Chinese ideas on what ought be legal are rooted in intuition for what we would call natural law rather than study of what we would call natural law.

I can't imagine Chinese people being concerned about the general case of lax data protection. I can picture a near infinite string of ad hoc outcry over things like the strawberry adverts.

Anyone from China disagreeing with my observations on your country, feel free to yell at me. I invite you.
Fair enough, you may be right.
In politics, quitting something like that is often just a social cue that you disagree with what's going on. Oftentimes there will be an identified successor waiting, especially for appointed committees with forced allocations of seats among parties.

Its far less meaningful compared to quitting a full-time job, but it sounds meaningful to people with full-time jobs. :-)
Just wait when coca-cola and friends fill the skies with their own logo constellations when (not if) space technology gets cheap enough. After all, it only needs to be cheaper than conventional ad campaigns to be viable.

Nobody has to look at it right?

Dismissing this issue as "overheated silliness" is extremely naive and short-sighted.
My take on it as far as truck drivers is that the pay for truck drivers (as they are today) will likely drop as the skill required to drive one drops from partial automation. Similar to how airline pilots of today's advanced jets are typically only "needed" during taxi, take-off, and landing.
> Before we dive in, an important caveat: You will become a sysadmin of your own mail server.

This for me is the deal breaker. I say this as a sysadmin.

It's all well and good running a single server but if that shits the bed then you have to deal with it immediately.

So to run something that doesn't require 24/7 support I now have to run a cluster of servers.

I'll also need something to manage those servers like salt/ansible/puppet

I also need to deal with being my IP blacklisted because of a previous owner, or just entire domains now delivering my email because they don't like the fact i'm not using $email provider

Then there is spam filtering and the constant battle that is.

Or I could just pay someone a couple of bucks a month to worry about all that shit and not worry about it.
Aha! Thanks.
A docker container would really be useful for that !
I'm here for only a week but I must admit I think about quitting.

I could always go back to my previous job (I only left because it's a bigger company and much higher salary). The only problem is that I moved to a different country and I signed one-year contracts (work, housing, etc.), so I'd ended up paying a lot of fines for breaking them.

It's fantastic.
Even once the problem is "solved", there's still an entire industry, one of the biggest, to turn around. Right now we still don't even get software updates for our head units in our car in most cases. As technology improves, how will self-driving cars adapt?

We change out our phones every couple years, but may car is five years old and I'm just about to finish paying it off. With a decade being a reasonable replacement cycle for a car, how will the car technology keep pace? Surely people aren't going to start buying iCars as often as they replace iPhones. Even if you adopted a service-only module for the industry, it's not like driving services will want to replace their entire fleet every two years.

Will cars have some sort of "technology package" including the computer and some of the sensor modules that can be made plug-and-play removable so you can upgrade your car?

And, again judging by the French revolution (and the Russian, and numerous others), an elite subset of the revolutionaries will seize control of the robots, and the situation will return pretty much to status quo ante, except for the identity of the owner of the boot stomping the average guy in the face, and their philosophical justification for their exalted position.
Do you think the designers of such services made them mainly for nefarious purposes (surveillance, exploitation and corporate oppression)?

Most of the things you mention has perfectly legitimate and useful functionality, they are usually optional and data is anonymized after a while, has option to completely disable / remove / see all data with a a few clicks.
According to the article, a stopped truck is in the same class of objects as an overhead sign, so a lot of false alarms would be going off if this wasn't also fixed.

Just my two cents, but agree completely. Remote lets me focus on my work better, and skipping the commute is a huge benefit to my mood overall. Plus far less gas, car maintenance, I can go for a run during lunch...

It's also hard to overstate the freedom it gives you - you can literally live anywhere in the US you please. It's not for everyone but I don't think I could go back at this point.
To add even more detail, as there still appears to be a lot of confusion:

The radar systems in these vehicles send out a radio pulse in a broad approximate-cone forward. They get bounces back from everything that reflects radio in front of them. Distance from the object is calculated by time between pulse and response. Speed towards/away from the object is calculated from Doppler shift of the radio frequency.

There are two main things that these systems can't detect.

1. Speed of the object perpendicular to the direction of radio wave travel.

2. Location of the object within the approximate-cone the radio pulse travels in.

Note that thanks to the second, you can't calculate the first with higher-level object tracking, either.

So the data you get back is a list of (same-direction velocity component, distance) pairs. There's no way to distinguish between stationary objects in the road and stationary objects above the road, to the side of the road, or even the surface of the road itself.

Radar just doesn't provide the directional information necessary to handle obstacle detection safely.

I honestly wish this was the law.

For a 65mph crash into a stationary object, that looks like fairly light damage considering!

Isn't this precisely the scenario that automatic emergency braking systems are designed to prevent?

The article suggests that no system can handle this, but the EuroNCAP system specifically tests cars driving at up to 80kph (~50mph) into a stationary vehicle (https://youtu.be/AJ4WXgWaNgs?t=2m40s protocol: https://cdn.euroncap.com/media/32278/euro-ncap-aeb-c2c-test-...) Is this sort of safety equipment not a "thing" in the US?

It looks like AEB is not fitted to the model S in the EU as standard. https://www.euroncap.com/en/results/tesla/model-s/7897 (expand safety assist section - no AEB listed, c.f. XC90 https://www.euroncap.com/en/results/volvo/xc90/20976)

I wonder if AEB was installed and activated in this crash, despite what the cruise control was doing? Surely it must have done otherwise I'd have expected significantly more damage, particularly to the fire truck getting a 2t lump slamming into it @ 65mph?!
A while ago I saw comments here about tmuxinator. Which was a fantastic improvement to my tmux use. Create a layout manually, get the layout from tmux and then set it up to launch a custom set of windows, panes, and programs based on my project needs. Doing this easily and repeatedly makes it trivial for me to set aside a task and come back to it later and be confident I will have everything in view that I need.

I've always felt that when building these incredibly valuable satellites one should consider building 2. I know JWST is probably not a good example with the work required to make the mirror but but in a lot of cases one could probably replicate a rare satellite during production for much less than 2x the cost. Then you have a flight backup, and alternatively you can later double your science with another launch if everything goes smoothly on launch one.

As said probably not a reality for JWST but these high risk launches always concern me with no backup option. What a tragedy it would be.

I never said outsourcing was a silver bullet.

Outsource where you can. Where you can't, share the responsibility.

All of this is subject to whether or not you can afford it. I made my assumption based on two breadwinners.

In my mind $15k is a not a breadwinner salary. I had assumed since you referred to yourself as a modern women who makes good money you'd be at least making $70k-$100k.

Last year or so there was a article about what sounds like exactly the same problem with radar. Overhead traffic signs and very reflective small objects confusing it. The argument was that Tesla is in a great position to deal with it because they have so much human driver data. If humans keep driving through the giant obstacle it's probably not a problem. Apparently Tesla instead decided to ignore the problem...

Some comments have intoned "it's not that bright," but from the article "It is expected to become the brightest object in the night sky for nine months"

Can anyone shed some information on this?

You are right, but that still does not apply to this situation. While decentralisation of populism would take power away from centralised influencers, Soros is not arguing against this decentralisation. Quite the opposite.

The internet has new forms of influencing power that the previous media did not have. What he warns against is the centralisation of those powers in the hands of a few players, and the possibility of these players working together with totalitarian governments to create a dystopian surveillance state (personally, what I am even more freaked out about is the idea of a decentralised totalitarian surveillance state - there was a recent Wired article on how China is experimenting with this).

The claim that Soros has a "strong states are fascist"-rhetoric does not make much sense either. This is what he actually says in the article:

> “The internet monopolies have neither the will nor the inclination to protect society against the consequences of their actions. That turns them into a menace and it falls to the regulatory authorities to protect society against them,”

There are no business incentives for Facebook and Google to clean up their act, so he explicitly calls for more regulation. How is that not asking for a strong government? Of course, that's not what GP meant with "strong states". His "strong states are fascist" claim is that weird kind of self-denial that you typically see with people defending fascist governmental actions, but not wanting to be called fascist.

It typically plays out like this: person A argues that "government X is fascist, because A, B and C", where A, B and C are typically human rights violations carried out by X. Then person B, who is pro-X, reasons "But A, B and C are ways for our state to be strong! X is not fascist, you are just against strong states!" No, person A isn't against strong states. Person B just has ridiculous definitions of what a strong state is. The governments of the Nordic countries enforce a ton of regulation on companies within it. I would consider that a strong government. Few would call it fascist. Person B would probably call it weak.
I’d hardly call space a finite resource.

I'm not sure how many people _really_ think that; it's pure fantasy. To be honest, I wouldn't be surprised if they're not obsolete in 20 years. AI stuff has a tendency to get nearly good enough quite quickly, and then improve very little more for decades afterwards.

>Did you catch the part about him being a Jew who survived Nazi-occupied Hungary?

Soros worked for the Nazis during the occupation and even remembered the time fondly, so he's not above violating the rights of others if it serves his own interests.
That is a leap in logic the article does not make. How did you come to that conclusion?
Great, NIMBYs now want to stop space development. And it's just for 9 months, take a chill pill.

Personally I think it's awesome, I'm going to try to track it and show it to my daughter. I hope one day we'll have structures on the moon that are visible to the naked eye! Can you imagine how motivating and achievable that would make space exploration seem to a new generation.
Road signs are huge.

Also the problem is a road sign or overpass over a crest of a hill. It's stationary directly in front of you, the road simply curves away.

EX: Here is a car in-front of a road sign. http://iowahighwayends.net/ends/June06/16/34exit263_99_halfm... We assume the sign is not on the actual road, and the software makes the same assumption. It's just not always true.

EX2: https://i.pinimg.com/736x/f7/11/eb/f711ebb462449a422151daab6... again perfectly safe but it looks like a static object blocking the road up ahead.
This has me thinking about how absurd privacy/protection of vision can be. If I stand in my apartment and face my photon receptors towards the apartment across the street, place some carefully constructed glass lenses in front of them, and receive photons from the sun bouncing off the surface of a pretty specimen, that is pretty universally abhorred behaviour. Of course this is absurdly reductionist. But interesting, nonetheless.

This could only be the law if and when politics did not influence decisions in the workplace. As that is not - and can not be - the case it does not make sense to ban talk about politics, no matter how futile such talk often is.
Might be I'm not the typical user of this, probably also because as a software engineer I know how much guesswork and unsolved questions lies in these systems.

Of course, I also notice that my focus changes a bit, but it still stays on the traffic around me and I would consider it rather improbable that I would oversee a stopped vehicle infront of me, not to mention a fire truck on a mission.

Maybe it's also that I'm driving daily in and out of Stuttgart, one of the main traffic spots in southern Germany. There's a lot of cars and ignorant driving, especially in dense traffic or jams. Plus we have a rediculous amount of roundabouts in the meantime and there are a lot of people that decide to either push into the smalles gaps, shooting in from your side and forcing you to do heavy breaking or other people approaching an empty roundabout, doing a needles near-full stop, accelerate, just to decellerate again, almost coming to another near-full stop to get around the corner (never understand the thinking behind this :-| ). I don't trust adaptive cruise control in either of these situations.
It's always like that; JVM is just way behind the cutting edge and people have to wait years to get access to latest stuff. I quit that a few years ago, now I go straight to the source, unhindered by whatever *VM is out there, even if it means learning new things every single day.
