Not a spacecraft engineer, merely somebody who has studied physics a long time ago, so take my answer with a grain of salt.

Basically, there are two ways you can design a cooling system: one that involves phase change, and one that simply transports heat from A to B by moving a heat carrier, usually a liquid.

Phase change systems typically have a higher efficiency, because the phase change has larger relative energy than heat capacity. But it also has two disadvantages: it only works near the boiling point of the medium, and you need to deal with all the pressure changes that come with a phase change.

The Parker probe seems to use a "mere" transport, and there the heat capacity and the working range of the medium is very important, and water is a pretty good choice on both of these criteria.

Oh, and you also don't want something very corrosive to destroy your expensive space craft from the inside :-)

IIRC the ISS uses two cooling systems, one based on water that is used throughout the station, and then an ammonium-based system that takes the heat off the water and transports it to the heat radiators. But on the ISS, maintenance is possible.

My other comment got deleted cause this was flagged while I was typing it. As someone who disagreed with the premise of the article, I'm ashamed that someone else would partake in censorship of this opinion. HN is not for one side or the other, and the expectation coming into HN should not be only finding people who agree with you. I'm certain that most of HN's audience disagrees with Paul Graham on fundamental political issues (including the fact that he disagrees with this very opinion in the article), and yet that hasn't turned HN into an ideological echo chamber where everyone disagrees with him. Flagging should be saved for spam or flame wars, not routine discussion of political issues relevant to startups.
When giving an actor a script that deviates from the proper script, you can choose to only allow deviations in the portions of the script that don't directly involve that actor.
Great point on how significant perspective is.
> There's little reason to believe many high-profile climate deniers are acting in good faith

These people act as authorities as well. If the alternative is to appeal to another authority, then it seems like choosing not to change opinions is a reasonable course of action for somebody who is already convinced on the basis of authority. The public case for concern about climate change has been marred with incessant exaggeration (for example, lady liberty was supposed to be semi-submerged by now, and the north pole was supposed to be completely free of ice by 2013). The source of many Americans' (and Canadians') skepticism of climate predictions is a continuous outpouring of exaggeration and fabrication, especially on the part of Al Gore (whose film was shown to a significant proportion of Canadian school children [and I imagine, American school children as well] in the oughts).
Actually “CO2” in the context of climate change discussions shouldnt be seen as the specific gas with the same name. Usually it’s a short hand for CO2e https://en.m.wikipedia.org/wiki/Carbon_dioxide_equivalent

I don't really think keeping the financial system (which is an integral part of an economy) functioning is the same as keeping an asset bubble afloat.

The US gov. certainly didn't stop the real estate bubble from bursting. It merely stepped in to recapitalize banks, and got its money back with interest in the process of keeping the financial system from falling apart. At the time, everyone was gearing up to make a run on the banks to get their money out first.
> I wouldn’t personally use probability 0 for cryogenics either, but if someone insisted on it the way to interpret that would be to say, “Out of uncountably many trials, a successful resurrection occurs only countably many times.”

It'd be a weird universe in which uncountably many cryogenics trials occurred, but I concede that the concept of almost-certainty would be relevant in that universe. On the other hand, seeing even trillions of occurrences (each with probability 0) I would still be forced to conclude that it was more likely that something with non-zero probability occurred, e.g.: I'm in a simulation, I'm going mad, I've been hallucinating for the last million years (I'm assuming here that one can only see a million cryogenic revivals a year), etc.

TL;DR from the title. 11 year old uses sql injection to change the election results on a voting machine at defcon.

In reading the headline I was expecting they would explain it within the first few paragraphs but instead buried what the kid did in the last 5 sentences of the article.

Like most of us though still alarms me that these machines are in use and have some easily exploitable vulnerabilities but as mentioned by one of the vendors in the article some/most of these exploits require physical access to the voting machine. Not to take way from the exploits but it would be pretty obvious if someone was doing this (plugging a device into the voting machine) on election day.
You are mangling the word "choice" to fit your argument. Solitude is (for instance) me deciding to have a day or a week for myself to hike a trail alone. Loneliness is not having anybody that would do the hike with me if I invited them.

Or to your more visceral examples: Medically assisted suicide could barely be called a choice (there are hardly any options with less painful outcome), but a suicide to avoid being hurt by others against your will is definitely even less of a choice.
I definitely agree with that, but they have pushed a narrative that "torrenting is inherently bad and should be blocked by ISPs/firewalls/etc" which means it's hard to use as a transport for software updates, video delivery and the like.
Uh, yeah, but a "small prop plane" is 1/50th of a loaded 18 wheeler then. Big difference between the plane here and a "small prop plane".
> Given that a large segment of the climate change advocacy also “coincidentally” support far left economic policies as a “remedy,” how can it be a surprise that people like me have a deep skepticism of the whole human-caused global warming debate.

The problem is that the right in the US is mostly denying the problem even exists, so of course all the economic proposals come from the left in this country. This is entirely self inflicted, and is not the case in other countries, where right of center parties mostly accept the reality of AGW and to some extent put in place market-based policies to address it.

I think the only way this works out is for the right to propose their own 'market based' solutions to the problem and contrast them with the 'socialist' solutions that the other tribe pitches (yes it is a strawman argument but that's the only way things seem to get done. The main thing is not to be Right but to be seen to be different from the other side). The problem is they have gone so far down the denial rabbit hole that it is going to take a long time to recover, and will probably take a generation to shift attitudes.

You might recall that the primary claim of anti-vaccination folks started with a blind appeal to authority.
Right, I meant that the issue was not responding safely to a malfunction. If it was undocumented, the operator should have paused the operation and attempted to contact the manufacturer. I don't blame them for their response necessarily (in the same way I don't think the programmers were actually guilty of a crime), but I think that should have been the main takeaway from this.
Being a mechanic, he was probably used to the pre-flight checklist (pretty much how to get the plane ready to fly). Then there's the takeoff checklist. It's checklists all the way down.

It's really not that hard. It's just consistency, talking on the radios, and years of experience to know how to handle anything unexpected that makes the pilot. Even then... there's probably a checklist for it.

There is a whole field of study--what was originally called software engineering--that does quantitative, empirical analysis of software development. Its practitioners are often called by managers entering into large projects that have tight quality requirements so that the optimal choices can be made in terms of tooling and techniques. (For example, large-scale automotive software, where there is far less tolerance for error than in IT.)
Doesn’t it undermine the credibility of NASA if something goes wrong? The public who is the audience for this article is also paying the bills (through taxes). I’d settle for just changing “won’t melt” to “shouldn’t melt”. I think that appropriate for something that’s never been attempted.
There is more in a script then just this actors lines. You could slightly change Lines of other characters in the scenes or you could change the descriptions of the scenes in slight ways. You would still give the correct lines to each actor and make it obvious who shared their script.
I've always felt that the biggest oversimplification in these diet conversations is taking too much about nutrition and what's 'healthy'.

Losing weight to combat obesity and just generally being healthy to maintain your weight are two different situations. You take meds to address specific illnesses.

Need to lose weight? Calories in and out is probably 80% of the nutritional knowledge you need. Everything else is just psychology. What keeps you consistent? 5 small meals or one big one? Try em both. See what sticks. Simple. Not Easy, but simple.
Does it happen more in America than in European countries with more socialist policies?
It's not an appeal to authority. That would literally be, "I'm a climate scientist, trust me". What's actually happening is: "I'm a climate scientist, trust me, but if you don't, look at this ludicrous amount of data and research gathered/conducted over generations".

Terraform is a much nicer way to deploy your CF templates than with the AWS CLI though. You can get the best of both worlds by deploying the templates with Terraform.
I have never seen a problem with being politically incorrect (I certainly have never tried to be PC and have made plenty of "offensive-sounding" arguments). Just do not be inflammatory, make the most offensive statements if you wish, and stop complaining when you get "instant refutation". Be honest in your arguments, do not try to defend yourself behind cries of "political correctness".
Glad to hear you're doing better, friend. Please keep it up. Taking care of the mind and the body is the right way to do it.
I think Terraform's multi-cloud support is a bit better than Cloudformation's. Jokes aside, I don't think the multi-cloud part is really the biggest selling point, the biggest selling points, for me, are:

- Much better than Cloudformation at telling you what it's going to change before you apply the changes and the ability to record those changes. (much better than those dreaded 'conditional' changes)

- The ability to import changes if you found some that were done outside of Terraform. It's not perfect, or easy, but mostly doable.

- The ability to look at the code, the state file and the plan to get a good representation of what's actually deployed.

Those three are more significant than it looks, but together it makes sure you:

- Don't get into a situation where automation is broken and you can only recover by rebuilding the stack.

- Don't get unexpected downtime because a change replaces a resource unexpectedly.

- Being able to track, record and manage changes in easy to read diffs and plans.
One would think those styles could easily be accounted for, just look how unique they are. A treasure trove of features just waiting.

The problem with disguises of this nature is once you know what you’re looking for you can easily adjust the algorithm and retrograde until you find the origin of your subject, assuming you have all the raw source data.

In addition anyone who has worked in this area knows the state of the art is in motion tracking and extracting the signals from an individual’s movements, which can be far more unique and works a lot better with lower resolution data and from farther away without the need to do expensive 3D reconstruction.

Contrary to what most people assume, these systems are more about localization than they are trying to recognize faces against some pre-known database, so just establishing cardinality is usually sufficient.

In an active shooter situation, having data on where the person has been, where they are now, and where they are likely to go next is the problem they are often times trying to solve. These systems can be used for evil like all tech but can’t we at least recognize the utility in keeping crowds of people safe and trying to mitigate death where time is of the essence?

I worked for one of the large banks that got out of this crisis pretty much unscattered. The Friday before TARP was introduced, which ended the succession of large banks collapses in the aftermath of Lehman, we were told internally that we didn’t think we could last more than a couple of weeks in the current market. And if we only had a couple of weeks left, most of the other (weaker) institutions had much less.

Like for the cuban crisis, I think it is easy to forget how close we got to the brink. We have already witnessed a complete collapse of the banking system in 1929, in a world that was much less inter-dependent than it was in 2008. It is survivable but it is ugly.

You are correct, but the point of the article is that the people manipulating the data deliberately avoid these types of corrections. They see a cooling effect in the raw data and say the scientists who apply corrections are the ones who are actually fudging the data.

afaik, extensions will not provide you with 100% protection in this case.

It could be for multiple reasons:
1. The 3rd party domain is not on the list:
a. Could be because the presence is not huge.
b. The domain is too new, and not available on any lists
right now.
2. The user might have whitelisted a 3rd party domain
because it breaks some component on the web.

They always need to catch-up, so it's a whack-a-mole game.

Along the same lines, a user can also control the referrer. for example in Firefox based browser you can control(globally) what info should be sent in the browsers itself. - https://wiki.mozilla.org/Security/Referrer . But this will also come with some breakage.

Similarly, blocking third-party cookies also does not help, as the leaks the telltale URLs will still pass on.

The legit use cases of these third-parties actually do not require the first-party to share these sensitive details.
1. Google analytics actually states that in their privacy policy - https://support.google.com/analytics/answer/6366371?hl=en
2. To load a font from CDN, I don't see why a company needs to send my booking ID and/or token to them. In some cases, domain might be needed but definitely not booking ID.

So, imo, the websites should take onus when implementing 3rd parties or atleast be transparent about what information is being shared and with whom.
Cloudformation has better atomicity guarantees though. It's not perfect but in general if a change to a stack fails it will get rolled back to a known good state. Terraform doesn't give you the same guarantee. You'll have to push a rollback or fix yourself leaving your AWS resources in a potentially broken state while you do.

> Before the 19th century, there was no such thing as a professional athlete. There were professional actors, but that was considered a borderline dishonorable profession.

And that changed with TV (and cinema).

In the 19th century an actor can play in front of one or two hundred persons each day at most. Now a good movie can be played in front of millions of persons. The same changes applies to sports.

Suggestions? Don’t do it.

Your family comes first. Why would you work full time at a company and do side work at the expense of your family?

Do you have equity in the company? If not, your employment with the company is solely a business arrangement. You give them X number of hours per week and they give you Y dollars.

If you can make the Y larger without changing the X, why wouldn’t you? Why would you sacrifice time with your family for a company? Do you really think if times got hard and they could lay you off and survive they wouldn’t?

Unless you have a decent ownership stake at a company, never confuse a company that you work for with your company.
Problem is that most of your examples are things where disagreement is actually a valid thing. They’re are all political in nature and different opinions are just that, opinions.

Climate change isn’t. It’s a scientific fact. On the same footing as the second law of thermodynamics at this point. There just is no disagreement to be had that isn’t as ludicrous as debating political sides of the flat earth “theory”

The only thing we should be disagreeing on is what to do now that we know these facts. Not on wether they are facts.

You're asking why we're not polite to the people destroying the world around us with their stupidity. Because politeness is secondary to having a world that's livable in. People get angry when others mess with their life and livelihood. We want to live, not to die and if others get in the way, politeness and kindness are inappropriate responses. It's not much different than responding with politeness when a country is invaded by others. Destruction is the end result in both cases so people get angry and rightfully so. It's either that or allowing your own destruction to happen. Not to mention that people do not listen to logic or reason. Trying to convince others who are fanatical about their beliefs with reason and logic is a waste of time.

I've been really thinking about this, and I have a follow up question. Attempted murder is a felony in the US. If denying climate change is really "going to kill us all," and climate deniers "are trying to kill [you] and [your] family," should they be jailed and prosecuted for attempted murder? If not, why? Are they not guilty of that crime?
I’m the wrong one to submit as I’m trying to learn more myself. Wikipedia entries are an easy place to start, and that should be straightforward to add to your index.

I think it’s problematic to have random people submit to the index with no incentive. I’m just becoming interested in tai chi, but I run no such webpage (who usually submits). There might be a way to gamify or otherwise incentivize people, but that’s a very non-scalable approach. Really only automated crawling can be done to significantly widen your index. It’s just very resource intensive... but good luck! I hope you can go far!
