Instead of being anxious, our goal should be to fix things if we can, and plan mitigation strategies if we can't. Peak oil is a thing: by definition there is _some_ global maximum in produciton volume over a long enough chosen interval. It might turn out that the solution is built into the problem though, because price is a function of supply so we get a soft landing, especially if we plan ahead. And we should plan ahead. It's the same with Y2k. It was a serious problem, but we fixed it before it was a disaster.

The Mathusian Catastrophe has also failed to fully materialize because people are not bacteria, and so we planned ahead and are trying to control population and improve agricultural efficeincey. Did we do a perfect job? No, but we did better than bacteria.

Just because a doomsday scenario fails to emerge does not mean the problems were completely bunk.

So I'm guessing Stross thinks we should imagine what will happen if we don't do something about Kessler Syndrome, and then become motivated to do something about it.
This is a great essay. And obviously pertinent!

I think the osmand model (lite/demo with 10 map downloads, paid version with unlimited, open-source with full features for free but you have to know where to get it and how to install) is fair.
My impression is that the issue he had with Rust is that it enforces memory safety. That isn't something that is likely to change (although I would be open to it if there were a lot of demand—yes, really!) The Rust community, me among them, seems pretty happy with enforced safety.
This works because you trust the HTML provider (as a source of a valid hash) but not the CDN. If you don't trust your ISP then getting trusted hashes becomes more interesting. You'd need an encrypted/unmodifiable connection to a 3rd party repository of hashes for HTTP content but that'd only work for shared identical content (like the stuff in a CDN). For personalized content (any website with a login) you need a personalized hash, an HTTPS response could have a header with a hash (RFC 3230: Instance Digests in HTTP) but you can only trust that if you trust HTTPS and if you trust HTTPS then what does the header really add? You probably need two ISPs or at least VPNs if you want to start detecting tampering by an ISP.
The first few times it was really slow, but recently it's only added a couple seconds to the transaction. I really think this will be a non-issue in a couple months.
If its any consolation to the HP folks, Apple did something similar with Motorola. The MOTO ROKR was intentionally crippled, and designed to fail. It was merely created to delay Motorola entering the media business on their own. Not that they would have been any more successful than HP had they tried on their own...
I believe that Blow values ease-of-prototyping more than safety, and sees all of Rust's safety guarantees as a distraction. Games have smaller maintenance windows than other applications, so caring about security is definitely a harder sell (especially if the game is non-networked, so the attack surface is already minimized).

That said, the existence of Rust's thriving gamedev community means that not everyone shares this point of view, but I think there's still plenty of demand for a more specialized language for this niche.

> Even a fleck of shed paint a tenth of a millimeter across carries as much kinetic energy as a rifle bullet when it's traveling at orbital velocity

True, but most of the other objects near it are also at or near orbital speed, so what's the kinetic energy when compared to an object it would actually be likely to hit?

(The situation in Gravity made no sense to me. The shuttle encounters the debris field every 90 minutes...why was that debris not also orbiting the earth with roughly the same period as the shuttle?)

Is the solution a matter of countries agreeing to "lanes" for orbits that differ non-trivially? (e.g. 300-330km is reserved for equatorial orbits, 340-360 km is reserved for polar orbits, 380-400km is reserved for retrograde orbits)
On that subject, I recommend to read Spin by Robert Charles Wilson. It is not exactly a Kessler syndrome, but for some reason, one day a kind of dome/membrane encloses the Earth blocking communication with every satellite. (Physical objects can still go through as far as I recall, but since you can't communicate with them, it is not that interesting)

This is good sci-fi book who won the Hugo award about the societal impact (with somewhat weaker sequel, but still enjoyable in their own way)
Who said Web server doesn't fall into that category? It benefits greatly from better performance.
> First degree price discrimination would be an auction system. We would see spots at Harvard, Stanford, and MIT going for tens of millions of dollars. Merit would mean money.

The problem with this is that if it were too rampant it would diminish the value of the product being bought. Harvard/Stanford/MIT are valuable institutions to attend partly because seats there can't just be outright bought.

If Harvard abolished its admissions system and replaced it with a $10,000,000 price tag per seat, the school would lose the majority of its prestige rather quickly, the quality of the student base would deteriorate even more rapidly, and it wouldn't be too long before even wealthy parents wouldn't be willing to pay that price tag.

The current strategy is probably reasonably close to the optimal long-term profit-maximizing strategy with the property that the school's prestige and reputation are maintained (or even enhanced) each year.

You're assuming the car doesn't also cheat on the "make install" test. How do we know the car isn't programmed to secretly leave the cheating software intact?

Whatever extra layers of software verification we attempt to throw at the problem can be defeated by extra layers of deception from the manufacturer.

Your car probably has it (behind the bumper cover). Helmets have it. Your home may have it. It's light, it insulates, it absorbs the energy of impact (once at least).

I don't know if there are effective, inexpensive substitutes for those uses.

It's not just about CDN-hosted files, it's also a way to not execute untrusted JS. Let's say you have a high-traffic WordPress site with a dev environment. You might have a clean theme and know all your JS, but be using plugins other people have written.

Using this it looks like you could put the hash in your markup and if their JavaScript code changed it wouldn't execute. For some people having that deadman's switch might be better than an always-execute policy on JS that you aren't writing yourself.

I think it's a little delusional to believe that if you just serve up the right ads people will tolerate it. There are plenty of people whose attitude is "no ads", end of story.

Also you can't get better ads without learning more about each user. In other words profiling, which no one likes either.
Yes, exactly. Reproducible builds can catch accidental differences, but discrepancies introduced by a malicious actor can still easily be hidden if they have complete control over the software and hardware.

yes. there may seem to be a lot of plastic in the world, but the volume of co2 produced each day dwarfs the total accumulated plastic.
Santa Cruz, CA has banned it for at least the 7 years I've been here... Jamba Juice serves in paper cups instead. I see no practical difference between the paper and the styrofoam (except I hate the handfeel of styrofoam).

It seems like companies have the processes in place to not use styrofoam if compelled to.
Why no one has solved event discovery – Hugh Malkin
Kessler Syndrome is a serious potential problem and it's certainly one people should be worrying about but it's mostly something that's only a problem for LEO where you have lots of things in a relatively small volume going very fast in different directions.

Further out in MEO where GPS satellites are there's a much greater volume, fewer satellites, and the satellites aren't moving as fast. There's no way Kessler Syndrome is going to start there. You do have a bunch of Russian satellites that loop in fast and close by the South Pole then go high and slow over the North, letting them spend most of their time being visible from Russia. Debris from from a cascade could kill one of those, which would cause debris that would kill some but not all of the GPS sats. It would be a relatively slow process compared to what would go on in LEO, though.

Satellites in GEO won't need to worry about Kessler at all. They're all in equatorial orbits, traveling in the same direction at the same speed. If one explodes its debris will only hit other satellites with the explosion velocity, not orbital velocity. So those should survive Kessler Syndrome fine, though you can't put any new ones there.

Also, Kessler Syndrom isn't forever. Satellites in LEO need to boost every once in a while to overcome atmospheric drag. As things get broken up their surface area to volume ratio increases and the fall out of orbit faster. Air density falls of exponentially with height so the lower reaches of orbit will become safe first. The inner reaches of LEO might be clear quickly but I have no idea how long it would be before orbit was totally clear.
Agreed. The simplest way I've heard it described is that whoever has the lowest level of EMV support is liable. So if the bank hasn't issued you a chip card, but the retailer supports it, the bank is liable. Likewise, if you have a chip card, but the retailer doesn't have the EMV readers, the retailer is now liable -- and that is where the change is.
I'm not a trust fund kid, but I could safely quit my job any minute and be okay for at least a year.

I'm 28. I have a net worth over $130k and a $25k emergency fund. I make over $70k (web dev) in a low cost of living area. I am maxing out my 401k and Roth IRA every year and will be opening a taxable account this year to dump more money into. I'm a renter (2BR for $515/month not including utilities), but I am fully supporting my fiancée who is finishing her masters of accounting degree.

I still spend quite a bit of extra money on video games and board games and a few other luxuries that I could and probably should cut back on. But I don't eat out (we cook in every night) and I live a mile away from my work.

My ultimate goal is financial independence. I want to be able to live off the 4% returns of my investments and not have to work (although I probably would do something, but more for myself than a company).

> it has no actual enforcement mechanism, especially on one-way missions

I don't see this article, or these end of the world scenarios, as things you should be anxious about. Maybe some people suggest they are, but to me an article like this serves two purposes:

1. To remind people who are in positions to solve this problem that it is still a problem, by bringing attention to the issue.

2. To give an interesting example of an unexpected negative externality of a system as a case study, which might help me think differently about systems I create.
Indeed. There were a bunch of security objections to the system by Ross Anderson et al at launch; it has turned out that EMV is not at all the weak link compared to online transactions, which are where most of the fraud is. Or skimmed ATMs, which don't seem to use the chip.

Of course it's easier to save money when you make so much, however I think the lifestyle is more important than the actual salary.

Just out of curiosity, does anyone have a link to an example breakdown of the costs per student in a typical university?

A full course load is about 12 hours total spent in class per week, for 16 weeks. Let's bump this number up to 20 hours, to account for overhead (homework grading, office hours, course design, etc). And given a class size of 25 students, that means 1 instructor can handle 50 full time students. If that instructor gets paid 100K a year, that works out to be 2K of instructor time per student. So what other overhead is involved that brings the cost of college up to 20 - 50K per year? You have the building, administration, potentially lab equipment, and teaching supplies (chalk/markers/copy paper/etc). But I still can't see that bumping the price up that much. Is the per-student share of the building cost really that high? Or are there 10 administrative staff for every one instructor?
Does Customs/Border Protection have access to domestic Amtrak reservations?
Okay, so these activities become drastically more expensive. That means that food is more expensive to grow, and to transport. This makes food from overseas harder to get.

(You might want to look at modern pea farming. I use peas because they don't seem like an exotic crop, but the process is pretty tech heavy. Peas are cheap (and fresh) because we have excellent short range weather forecasting.)
Rational people tend to be rational. And rational people don't dismiss the views of others because they don't share them.

Well, rational people can and should dismiss the views of others because they don't share them... if they've taken the time to investigate the validity of those views. Isn't that the point of being rational?
Thanks for the "beautiful layout", and I'm sorry about the javascript "problem". You can find more infos in our blog, at http://fairbooks.co/blog
I'm not seeing how size would prevent the attack. If I understand bugmen0t correctly, in the attack outlined, the file "evil.js" size (and hash and contents) are completely controlled by the attacker. If you did need to specify size, the attack would simply change to:

3. the XSS attack is loading <script src=www.victim.com/evil.js hash=foo size=123>

> If you include that, my understanding is that crafting a hash collision is into the realms of impossibility.

Crafting a hash collision is already in the realm of impossibility. (They're using cryptographic hashes: if you can make SHA256 collide, we have bigger problems.) The attack here isn't that you're getting the wrong file, it's that you're getting a file the webserver does not have, at all. Step 4 is where we go wrong: we load the file from cache, while we should instead request it from the server, which will 404 the request because it does not have the file.

(And it's JS: even if size did matter, you can just add spaces to the end…)

French here,

I've been a web developper for more than 15 years now and I try to follow what's going on with digital laws in France and Europe thanks to "la quadrature du net". I try to inform people around me but most people don't have any interest in digital laws, because 1) most medias don't talk about it or in a caricatural way. 2) People and most member of parliament don't undestand these laws. 3) Lobbys knows 1) and 2)
The results is that any digital law bills can be passed along easily as long as it doesn't disturb any strong lobbys in place as media won't talk about it and people and member of parliament won't speak up anyway.

Those who understand why these laws could turn very bad are a really small minority, and small minority without lobby means can be very badly represented in a democracy. Honestly I lack imagination to think of something more to do that could make significant change here.
