I can appreciate a quick coffee, but around here most people just use instant for that use-case. Some people seem to prefer the taste of the pods, but I don't find it much different. Instant is considerably cheaper, and also keeps from adding the clutter of a coffee-specific gadget to the kitchen.

> But I do know there's plenty of other interesting stuff (much of which is actually useful) we don't know about physics at other scales which we can spend our time and money on.

Yes, true, but the low-level stuff only describes. Theory formation attempts to explain. Explanations are required for science.
I'd like a reliably quantum source of random numbers to make certain decisions for me.

That way, if the many-worlds model is true, I can console myself that even if my decision turns out to be a bad one, at least many of my parallel-universe counterparts have made the other one.
Those not personally involved in the conflict would lack the motivation to develop a service like this, and for those who are involved it must be difficult to remain neutral given the circumstances (though I personally would appreciate if they try). An unbiased source with objective independent coverage of these events is tricky to come across, I suppose.

> All these horrible comments, just because she’s a woman

Huh ? Are you kidding me ? She's not just nobody. She's a feminist, who is very vocal about her opinions, has tons of viewers, and obviously have very polarizing opinions about video games and the place of women/girls in it.

Claiming she's "just a woman" is ridiculous. When you expose yourself, become popular and have lame opinions about some stuff (yeah, obviously I think most of what she talks about is BS), of course you will get a certain number of people who are violently opposed to you, and not just because of your gender.

It's like saying "people don't like Phil Fish and want to murder him just because they are jealous" or something.
California Lemon Law
The California Lemon Law is also known as “the Song-Beverly Consumer Warranty Act”. It was adopted by the California legislature to protect the rights of purchase’s whose car appeared to be a “lemon”. Lots of cars are repurchased by the automobile manufacturers every year under the California Lemon Law, which appears to be one of the most consumer-friendly lemon law statutes.

Alcor is a non-profit, and they're not implying anything other than the truth, which is that you're unlikely to get unfrozen, but it'd be cool if somehow you could be and maybe one day someone will figure it out.

And this is exactly why more research should be done to figure it out. Human creativity when provided the right incentives and not over-regulated is a pretty powerful thing.

Future generations may look back on us as unbelievably primitive and may have trouble believing that we suffered physical death and thought it an inescapable and acceptable part of life.
I thought the comments on some articles were bad, but apparently cryonics takes the crown. It's sad that our community can't discuss this topic without a flamewar.

Instead of going back-and-forth in comments, I think it would be much more productive to link to some FAQs or well-written articles from both sides. The current level of discussion is unworthy of us.
...the internet of things that you do not really own or have any control over anymore.

This is just a step away from e.g. toasters that won't toast anything but "authorised" bread (packaged in cartridges for "convenience", I'm sure...) A lot of this vendor lock-in has already been happening in the computing industry with things like printer cartridges, but as more and more appliances become "smarter" the incremental implementation costs of lock-in decrease so it becomes more widespread.

On the other hand the saying "when there's a will, there's a way" fortunately continues to apply, so we see "breakthroughs" like this. However, the frightening part is that this will no doubt be considered a "flaw" or "security breach" by some, so the systems gradually become more secure over time, and sadly this is security against the users. I could imagine this easily escalating into use of cryptography, which might then result in firmware hacking, countered by even stronger cryptography (e.g. signed firmware updates), leading to hardware hacking, stronger antitamper hardware, etc.
Similarly to what others have mentioned, I've also found Hartl's Ruby on Rails online edition to be the most comprehensive and impressive tutorial yet. I'd already had a strong foundation on Git, Heroku, TDD-testing, etc. but it was nice to see how they integrated so well with a Rails project and I personally believe they are both beneficial and critical for any web application development.

However, after a cursory glance at the tutorial, I was surprised to see how embedded Cloud9 was in this new version and that seems to be the route Hartl has taken. I'm wondering if anyone has used Cloud9 and what impressions they have?

Great work! Looking forward to taking a deeper look into the tutorial.

Even if one day it will be possible to revive these bodies from the scientific perspective, a huge legal problems would be involved. I mean, they are officially dead. Risk is even bigger if cryogenics became popular - combined with ever increasing population I doubt future politicians will be enthusiastic about the idea of dead people coming back to life.

Physics isn't a popularity contest.

Yes, but that doesn't change the definition of entropy -- it just borrows energy from somewhere else.
Even if they print an entire logo in the ink, someone could sell some kind of reusable sticker with that special-ink-logo and just stick it onto the non-Keurig cups during use. When finished with 1 cup, remove sticker and stick it on to a different cup.

I don't see why they even bother trying to lock down their machines TBH as it can't be done well without significantly increasing the cost of the machine or cups (or inconveniencing existing customers).

I have a Keurig (non-DRM) and buy mostly Keurig branded cups anyway but if I had to buy one of these "2.0" machines with DRM, I'd just not buy a Keurig machine.

Scientists plug into a learning brain
That would be very creepy indeed. But I guess at frozen temperatures, your brain activity would be nothing like at 20C, so I'm not sure how large is that risk - people who have been found frozen in avalanches usually (if I remember correctly) did not report they an horrible experience of being frozen when they came back to life.
"size differences are illusory"

So two things standing next to each other are the same size as one thing alone?

Damn hard to imagine. I would think "size" does not really "exist" but is a man made concept. And by its definition, two things next to each other form a "bigger" thing.
> The current level of discussion is unworthy of us.

I'm not usually one to be a buzzkill, but I should point out that Hacker News is largely filled with startup coders and small business owners, not trained academics - you can't set your standards too high for rational debate, especially considering the level of religious wars coders start over trivialities like text editor choice, operating system or programming languages (check out any thread that mentions PHP for a great example of group-think flaming).
To be honest, I did not experience it first hand myself, because I've read this behaviour from many other people.

They may be doing more, but they're not solving more problems or adding much more value or productivity.

Most new 'apps' just re-brand the wheel and make it more 'fashionable'.

I used to blame the web, but know the same 'push software out to make monies fast' mentality is even hitting desktop software which is far more bug-ridden.

Software engineering is largely dead. We're in a world of throwing apps at the wall to see what generates money as quick as possible and move on to the next thing.

The web (and mobile devices) will kill personal computing as it alllows corporations to take all of the control away. Sure, you can customise your UI, but it's already been dumbed down.

Massive Internet Outage Points to Flaws in Policy and Technology
I predict that the Keurig 3.0 will be Internet-only. Using an expanded Hyper Text Coffee Pot Control Protocol: http://tools.ietf.org/html/rfc2324 for management. Surely no DRM opponents can complain if they're using standardized protocols.

Using an app on your phone, you'll scan the coffee pod you want to use (your phone takes a picture of you via the front-facing camera as a security measure; much like ATMs have cameras); this connects to the central Coffee Server to generate a one-time passcode. Then your phone does a BREW via HTCPCP to the Keurig, providing an K-Authorization header. Having the encryption key for the one-time passwords be stored on the server avoids the mistakes problems Sony etc. have had where private keys inside devices are compromised.

Requiring a smartphone could present interesting branding opportunities, e.g. co-branding the Keurig 3.0 with iPhone 7, social network integration (click once to post the coffee you're drinking to Facebook), automatic reordering and possibly integration with health services as your coffee drinking data can be shared with your health care provider who can adjust your insurance accordingly.

When I looked at the output of the hash function in Python for integers a few weeks ago it looked like the identity function was being used. You'll still have greater complexity than an array, but I'm not sure how much greater.
> Why is the dot/period character used as file extension separator?

Why not? Maybe it was realized that other candidate non-alphabetic symbols were already reserved for other things, like '/' as a path delimiter on Unices, '\' same purpose on Windows, '#' as a comment delimiter, '%' as the modulo operator, '|' as the command pipe symbol, '^' to signify either power or exclusive-or depending on context ... we're quickly running out of candidate symbols on an ASCII keyboard.

It's expensive to preserve people near-indefinitely, and they invest their money with that in mind. There are no billions because it doesn't cost that much (~$75,000 for neuropreservation and ~200,000 for whole body). As it is, I think they do very well with their resources - remember that cryonics is still such a small field, and Alcor are the largest company by a significant margin.

Under what circumstances is that the case?

Let's suppose, for instance, that two roads diverge in a yellow wood and you have reliable information that road A is the correct path with 90% probability and road B is the correct path with 10% probability. The normal person takes road A and will be right 90% of the time.

On the other hand, if you try to be probabilistic about it and follow road B with 10% probability to reflect its 10% probability of being the right road, then your chances of picking the right road are 0.90.9 + 0.10.1 = 82%.

Maybe there's a more complex situation where the weighted random decision making is a better idea, but I'm not seeing it right now.

Let's assume they find a way to start waking you up, they will need to experiment for many years getting this process right. The first 100(0?) might wake up and remain in perpetual hell (no sensory input for instance or having some parts of the brain operational and others not) during that experimental time which might take years or might even never end.

Exploration of dying & waking up was nicely penned down by dying writer Dennis Potter in http://www.imdb.com/title/tt0115230/ and http://www.imdb.com/title/tt0115140/ .
Making data "utterly corrupt and worthless" is actually really hard, even if you're deliberately trying to erase it. That's why we invented secure disk erase programs (eg. http://en.wikipedia.org/wiki/Gutmann_method), because people keep inventing better ways to get back 'deleted' data you might not have wanted them to see.

This goes triple for the brain, which is analog and highly redundant. You can have large chunks of your brain physically ripped out (examples on request) and still live a pretty normal life afterwards, unlike modern computers where a single off bit can crash a program.

How do those numbers make sense? 300k to maintain a body indefinitely? Then pay for the operation to revive the body? I just don't see it. Not to mention there's nothing you can do to make sure that someone 1000 years from now will see the contract through in good faith.

"... it has almost no affect on the bandwidth." - looking at those numbers it's not the case at all, those numbers are really low to start with (as AWS isn't exactly the fastest) but obviously this would be much more noticeable at the higher end of the scale when we're talking about 100-200MB/s transfer rates, not to mention nearly doubling the latency!
Do you actually think the point is to argue with people who actually know things, like a lawyer instead of a scientist? Using a modulo operator is the obvious solution to the original question, and cowardly anonymous downvotes can't erase simple facts -- but they eventually make them have so little contrast on the display that they become unreadable. What an achievement.

I think it would be supporting libraries. Looking at RedMonks's statistics[1] Pascal doesn't even feature (I was able to find ~600 on GitHub). By today's standards that's a pretty big shackle, you'd have to write a lot of functionality yourself (although that's ignoring that you can use C libraries with a little effort).

I love the language, it just had no staying power. Maybe people just prefer curly braces.

The similar IO model? It is just the Unix IO model though, with the caveat to never use blocking IO. Tcl doesn't force non blocking IO like Node, you have to do it yourself.

Event based IO was around by 1999 or earlier, according to the C10k page that we all avidly read backin the day http://www.kegel.com/c10k.html

Just a side note: the Gutmann algorithms have nothing to do with defeating better methods of recovering data.

He created optimal patterns for each drive controller he had available. You would only ever use the full set if you didn't know what controller you had - otherwise using a single set would be fine.

Gutmann himself says that a few overwrites of random data is about as good as you can do.

Compared to magnetic tape wire recording is quite robust, which is why it's not surprising they've survived over half a century. The heat resistance is one of the reasons why wire-based recorders were used for aircraft CVR/FDR - the Curie temperature of steel is far above the point where plastic/organic-based tapes would be incinerated.

I can almost imagine a page titled "Recovering old family recordings made on aluminium platters" many decades from now... and wonder if the chances of success would be nearly as good. :-)
