Wouldn't this be limited to something like 10Gb/s throughput? That's not much compared to a GPU bus. Cool idea though. I wish this press release wasn't so light on specs.
Best Startup Interviews – A place for lean startup ideas, tips and tricks
After reading The Dark Forest, my bet is that an advanced society would never advertise themselves in such an obvious fashion.
This really tells us extremely little about advanced civilizations, beyond that we haven't seen them doing a few variations on a very specific activity—harnessing all the stellar radiation in their galaxy.

There are huge number of assumptions based on that idea. A fundamental one is that a civilization in a relativistic universe would grow to densely inhabit a galaxy. Another is that they would need that much energy. Another is that even if they did have need for that much energy, they'd bother collecting EM radiation from stars.

That third is an interesting one to me. Now, you could muck up the night sky for the entire Milky Way, or you could, with Sufficiently Advanced Technology (tm), annihilate a total of 10 Jupiter-masses a year across the whole galaxy. For your average star system, that's extracting energy from 1.1 billion kg of mass a year, or roughly what NYC's garbage collection services dispose of every two weeks.

Pondering that, I suspect it's the wrong idea to imagine that a very advanced civilization, something we can only understand in the dimmest sense, would be constrained by something as specific as stellar energy emissions.
Or another future - as more people see Google and Azure can compete... they build cloud agnostic software that treats providers as a utility, and profit margins fall and fall.
This article has lots of false assumptions.
I agree.

In fact, this article is so preconcieved reading it's last sentence felt like: 'scrolling, scrolling to continue reading after the ads... aaaand... where is the reasoning-part and the criterion-part of this piece?'

Considering the article's lack of substance and the subsequent unquestioning cheering here on HN, this article delivers less enlightenment on the future of EV than it is a statement about the bias on HN towards EV. And probably about the bias in the valley as well.

Assuming you consider the dimensions/axes/whatever of the 2d space to be indexed by reals (which is conventional), then yes one can construct a bijection:

- normalise x and y coordinates in the shape into the interval (0, 1)
- interleave the bits of the normalised x and y coordinates

This gives a single real value in the interval (0, 1), which exists and is unique for every point in the space (so it is an injection), and it covers every real number in that interval (so it is a surjection).

This gives you a bijection between points in (a) 2-dimensional space and a segment of the real line (which, in turn, has a bijection with the whole real line if you want to specify that).

Once again, cardinality in set theory is based on injections and bijections. If there is an injection from X into Y, then Y is at least as big as X. If there is a bijection between them (i.e. injections in both directions), then they are the same size.

(Also, bijections are inherently bidirectional.)

Down the road we'll be able to add support for specialized lab equipment in a case by cases basis.

For Windows only software, Docker and Microsoft seem to be making progress on that front. It's still to be defined how it's going to play out.
Fortunately there are many cross-platform alternatives for most scientific software (at least in the AI area). Curious to know, do you have a particular software in mind?
Why doesn't an open source photo editor as good as Photoshop exist?

The answer to both is that both require highly talented programmers and designers with a lot domain-specific knowledge, and most if not all of the people who fit that bill are getting paid to do it commercially.

1. e + ei is not real.

This function maps all real numbers to irrational numbers, 1-to-1.
So what (legally) happens if my phone stores data in a way that this device isn't designed to process? Unlikely since I'm sure they support all major mobile OSes, but I could see it happening occasionally.
Why should an advanced civilization necessarily create the artifact mentioned in the article. The conclusion because we don't see this artifact, so type III societies don't exists seems too strong. Maybe they don't create giant veils around galaxies and instead have virtualized themselves, or can simply convert matter to energy at will. What use would there be in wrapping a giant ball of dust around a galaxy when you can convert matter directly to some other energy/form?
Probably I think "they" are formless and more information based than physical. We aren't even sure if this reality is real or a simulation anyway, so why limit our thinking to advanced civilizations in the world as we know it?

I know some people on HN do not have respect for RMS, but lest we forget he is a true Hacker who built very useful pieces of software, GCC, ls, GNU Emacs, GNU Bison, just to name a few pieces of code that I almost use everyday. Some interesting facts about him are that he has been awarded 15 honorary doctorate degrees.
On the contrary having a big runtime is what makes a language portable by abstracting it from OS specific APIs.

I only care about OS specific code when using C or C++, not any other language with richer runtimes.

Actually, C's runtime is called UNIX and is packaged as POSIX for non-UNIX OSes.

Any C or C++ developer that wants "portable" code needs to litter their code with #ifdefs, for any dependency not on the standard library.
> they build cloud agnostic software that treats providers as a utility

It's like browsers all over again. As long as each provider is offering different things or different implementations of the same thing we will either need to choose one or be forced to go through a lowest common denominator translation layer.

MSFT, GOOG, and AMZN are all smart enough to not turn this into a race to the bottom of who can provide the cheapest scalable instances. They'll all try to differentiate on features and so it's going to be a long time until you can treat these as a utility.

Textalyzer isn't the judge, jury, and executioner here. You're not going to have your phone scanned and then be immediately carted off to prison for the rest of your life because an app sent an auto text.

All of the data it pulls from your phone is going to _evidence_ that could be used in court.

I'm still not on board with it, but I don't think false positives are as big of a deal as people here are making them out to be.

Compared with a googol our Universe has negligible atoms , 10^100 - 10^80 = ~10^100

Compared with a googolplex (10^(10^100)) the entire Evrettian metaverse is negligible as (10^(10^100) - 10^80^2 * (average quarks in atom) * leptons(10^200) * dark multiplier(10^2) = ~1 googolplex

Has anyone ever used a googolplex for anything ?

One thing that really stood out to me was that Ramunajan got lost in the traditional system of Academia which persists even now. There could have been (and may still be) so much talent out there that may never get a chance.

I'll take all these improvements with a pinch of salt until they are actually in the wild.

Take the lighting network for example. The idea has been floating around for quite some time but in practice its still vaporware.

Yet, ask any bitcoin enthusiast what's being done to solve the scalability problem and the LN is trotted out as if it were already widely adopted. It's ridiculous.

> the whole thing is encrypted as a blob

No, it's not.

With pass (just to be sure - we're talking about zx2c4's one, right?), the store contains a bunch of independent gpg-encrypted text files. However, the filenames are not encrypted or obfuscated by any means.

This has pros and cons. On the good side, you don't have to decrypt anything (which means, actually use your GPG key, which is best kept on an unplugged HSM) to just check if the credential's in the store (think auto-fill suggestion). Also, this architecture allows dead-simple (plain rsync or git!) approach for synchronization when there are no entry-level conflicts. On the bad side, anyone who has access to the filenames (local filesystem access or a clone of git repo) can figure out which resources you have credentials for. That's the price of the simplicity.

I.e. what you see in the very first example at https://www.passwordstore.org/ in the "Using the password store" section are the actual at-rest filenames. Run `ls -lR ~/.password-store` if you don't believe me ;)

Use of ecryptfs/encfs or git-remote-gcrypt was suggested to mitigate this, but those aren't perfect. Well, everything depends on the threat scenarios you consider.

I tried out one of the CareKit apps this morning (I think the first four were released today) and they're really nice. Very simple, good use of notifications to remind the user to take pills/add progress, and they're still useful even if your doctor isn't signed up.

I wonder why Apple is the only big company doing something like this? It just seems like a really great idea and I'm surprised Google for example hasn't got in on it (that I know of).
Who would decide which BOINC projects work with Bitcoin? What if I made a BOINC project for calculating the number 4 and did it before anyone else noticed it was available? How much bitcoin should that be worth? There have to be ongoing decisions about what BOINC projects are accepted and how much they're worth. Who makes those decisions?

More realistically, what if I privately know a fast algorithm for an obscure type of protein folding, and then I push for a new BOINC project to be accepted that focuses on the specific type of problem? I'll be the only one that can mine it efficiently for a long time. If I calculated my expected profits, I would probably see that it's worth it for me to pay a lot of money to lobby the people in charge of the BOINC-coin decision process to get my project accepted. Unless BOINC-coin only uses a fixed set of projects over all time, or is only worth negligible amounts, then lobbying like this is going to influence what projects it accepts.

Even if BOINC-coin uses a fixed set of projects, then there's a problem of what work units are given out. I imagine many projects work like SETI@Home where some data is given out to users to process. If processing the data is worth money, then it might make sense financially for me to artificially construct datasets that I've already solved, and bribe the SETI@Home administrators to insert my dataset into the worker queue, which I will then quickly "mine" for BOINC-coin.

A BOINC-coin isn't fully decentralized. It requires trusted people to be in control choosing which projects are worth it and to secure the authenticity of the data sets. Bitcoin is about minimizing the need for trust in administrative systems like this.

Even if you solve the above problems, the proof-of-work system needs to be hard to compute but cheap to verify. Many BOINC projects' work units aren't cheap to verify. They just have several users redundantly recalculate the same work units to check that they get the same answers.
At first glance I think they would take off and be airborne. Other than that they would do whatever they were programmed to do.

According to the ACM website, it is the 2015 Award, not the 2016 award (as the HN title currently states).
Certainly there are exceptions to what I said - there's always an exception. But I think the picture painted in your comment is the exception, not the rule.
> That neglects the fact, that most of the maintenance costs are not engine related. Like the brakes have to be regularly checked. It neglects the fact, that a battery will wear out sometimes between 3 to 6 years and has to be replaced, which is a huge cost related issue. The guarantee Tesla has, does not help, because you will pay for that guarantee otherwise.

It seems like the battery management of Tesla is pretty good. I'd imagine 10-year to 15-year replacement of battery packs... which is still far more expensive and costly than a transmission rework (ie: a 150k to 200k Camry).

Shame on them! 90% of tools they use either draw inspiration from, or use, or built using, or licensed using his ideas and implementations. Stallman has more fingerprints over the world than any 2-bit hacker here.
Well deserved.

I sometimes wonder if the Googles and Facebooks of today would have existed if Stallman didn't have started the GNU movement with their excellent developer tools. In a way, he has created his own demons.
I'm new to the comments section here but I find it hard to believe people in this community would not have respect for RMS and what he has done for the industry.

Even if Facebook itself saw a decline, the business could still be quite successful from their properties alone.

To be fair, Bill Gates or Larry Ellison would just need to say the words and they'd get the CEO position back in a millisecond. As would Zombie Steve Jobs.
Most of these ideas will not have mass-market appeal, precisely because this is a tech-centric market.

I could have submitted an idea like this:

Instagram for Pets
OR
Tinder for food

I would probably get about 3-4 upvotes on HN, but a "stupid" idea(s) like this could easily get 1+ million app users the same way "Yo" did.

What you guys should have used the Apply HN for is to fund ideas like "open-source as a business". Rather give that money to GitLab-type ideas so that even if the founders fizzle out, the IP remains in the open and can be used by everyone.
You don't need to own a whole datacenter to own machines located in a datacenter, my company keeps machines in a 4 rack cage in a datacenter. (and plans to empty that cage by the time our contract runs out in September to finish the migration to AWS). Our AWS bill is just a bit higher than what we were paying for the cage rental + internet connectivity alone.
I didn't say anything about that being how humans learn. Neural nets are only vaguely similar to the neural networks in organic brains anyway. But this is how our (non sentient) AIs are trained and what distinguishes them from predetermined deterministic algorithms. It allows them to operate more independently from humans than 'traditional' programming techniques.

theres not much to be gained from arguing about the definition of intelligence, but however we use the term I think the above is what distinguishes these systems. What term would you prefer to use for them?
Same...But good to know that it is executing well.

One significant advantage of AWS is that they have a very large, built-in retail customer with relatively demanding requirements. I've always been under the impression that Microsoft doesn't really have a business that would lend itself to consuming its own services[0] and it's unclear to me whether or not Google uses their stuff internally.

I recently helped a research group at a healthcare organization build a HIPAA-compliant version of mixpanel into their application to help patients with CBTi.

The app used this XML-based framework to manage the formatting of the questions so that the researchers (who were pretty tech savvy) could manipulate the questions. The XML-framework itself was a bit of a mess, but it got the job done. However, as new iOS releases passed, this XML-based framework slowly became outdated and required some extra work to maintain as time went along. Having an Apple-approved way to build surveys seems like it is the solution to that problem.

I could see a researcher who was technical enough being able to extend CareKit to be able to manage their own study without the help of a dedicated iOS dev everytime they needed to make a change to a question or survey. Part of that is CareKit, part of that is the fact that Swift seems more approachable than Objective-C. This was included in ResearchKit, but CareKit provides a way to track if people have completed daily steps and visualizing that for end users. It only took me 5 minutes from cloning the demo app and plugging in my HealthKit Entitlements that I was able to extend the sample app to track Asthma Inhaler Usage.

EHR integration will still be a challenge, but these are the type of things that my team working on Redpoint at Catalyze will work on like we did with HealthKit on it's release.

If you want to check out how I extended the sample project to include a new activity to track, you can check out my fork here: https://github.com/molsches/CareKit

"The distance between 0 and 2 is larger" is a question about the metric of the space, not size of sets. There are the same number of points in both sets, since f(x) = 2x is a bijection between them.

Try to make arguments from axioms and definitions rather than asserting things from intuition. Intuition is often a useful tool, but (1) it's not an argument, and (2) it's not very helpful once you step into the infinite realm. Incidentally, that's why I went for programming: it's like math, but with no infinity (unless you're using floats, but that's a much easier infinity).
I was also surprised to see Michael Luby there. I know he's a brilliant guy and I'm appreciative for his contributions to Fountain and LT codes, however the old debate of software patents come to mind. I wish we had a better system in place.
