It occurs to me that mitochondrial decline also seems to be an important aspect of aging. If you can just infuse mitochondria through the blood and "the organelles will gravitate almost magically to the injured cells that need them and take up residence", that suggests a rather obvious rejuvenation approach.
> it's a science curriculum, not a vocational school

I griped about this to my CS/SE professors until my senior year of college, when I finally understood why they were teaching us all these weird languages and styles instead of the C/C++ that I assumed everybody used at the time: Programming languages come and go - hell, entire platforms come and go - but the underlying concepts (and the ability to teach oneself) are forever. I haven't written a single line of C/C++ professionally, but thank goodness I have the mental tools necessary to pick up all the different programming languages, libraries, protocols, etc. I did end up using.
That's fine, why not? Isn't this the whole startup thing? Burn money until you IPO or get acquired? Otherwise it is look down at as 'revenue business'.

I believe you’ve misunderstood the concept of single point of attack.

This means single point of attsck for everyone with an ehealth record.

With paper records, or in-house digital records, a hacker / thief, or malicious government, or what have you, has to compromise many systems.

The same applies to your paper record comment.
Hi HN! Super happy to announce the first open-source release of the Hasura GraphQL engine.

This is a standalone service that gives you GraphQL on Postgres. It comes with fine-grained access control that can integrate with any auth provider. It can also work with any existing postgres database as is, and allows you to expose select tables/views across your postgres schemas over GraphQL.

Looking forward to your feedback!
The "Ludic Fallacy" strikes again [0].

> The ludic fallacy, identified by Nassim Nicholas Taleb in his 2007 book The Black Swan, is "the misuse of games to model real-life situations."

...

> The alleged fallacy is a central argument in the book and a rebuttal of the predictive mathematical models used to predict the future – as well as an attack on the idea of applying naïve and simplified statistical models in complex domains. According to Taleb, statistics is applicable only in some domains, for instance casinos in which the odds are visible and defined.

Both Taleb's books, "The Black Swan" and "Fooled by Randomness" are an interesting take for such models. Meanwhile, most economists know about "Knightian Uncertainty" [1] which talks about differentiation of risk and uncertainty.

> "Uncertainty must be taken in a sense radically distinct from the familiar notion of Risk, from which it has never been properly separated.... The essential fact is that 'risk' means in some cases a quantity susceptible of measurement, while at other times it is something distinctly not of this character; and there are far-reaching and crucial differences in the bearings of the phenomena depending on which of the two is really present and operating.... It will appear that a measurable uncertainty, or 'risk' proper, as we shall use the term, is so far different from an unmeasurable one that it is not in effect an uncertainty at all."

Hello everybody :)

For the past month I've been working on a service to easily manage feedback from your customers.

One thing that I found missing in other tools was painless process of leaving feedback. Some took it too far with on-site widgets that interfere with more important things like Intercom. With FeedBear your customers can leave feedback right from the Intercom widget, with no extra account needed. If the choose to stay in the loop, they can leave their email to receive an invitation.

With an account created, your customers can vote and receive updates about your progress. You get to see who voted for what, who are the most active customers and the most important: what to build next.

If you have any questions, I'm ready to answer them.
Enjoy!
I have no idea, I only ever use the trackpoint! (Yep I'm another one of those guys..)
This is true "on paper", but in practice our whole industry is built on the fact that electronic records behave qualitively differently from paper records because they're so much easier to handle.

You can't steal everyone's paper records all at once in the way you can with electronic records, for example.
Paper records have a better scope. It isn’t economically justifiable to steal paper. Electronic records are easier to steal and cheap to sell, mine or otherwise utilize.
Never heard about this guy, but after seeing one of his shows (the one with the skeleton puppet) I find him very funny. Thanks for telling me about him!
I don't know. How would you feel if someone would call you a pedophile on social media, but deleted the comment after a couple of hours?

Especially by a person who has a huge following and every word he writes can have a massive impact on peoples perception. As a lot of people pointed out, the term pedophile can be very damaging on one's life. Now put these two things together...

With great power, comes great responsibility. When you are a leader you have to be careful what you say and do. Granted, we are all human, but deleting a tweet doesn't even come close to an apology.

As a Helsinki resident (and Whim user) it’s important to point out that while the user base of Whim has grown quite a bit, it’s most likely due to the introductory price that won’t last forever. For 49 € you get public transport, public bike (first half an hour free), cheap taxi rides and perhaps slightly cheaper car renting, whereas to get public transport alone without this app is around 55 €. So I wouldn’t call it a success just yet.
The implementation in the article is less important than the concept of making notes as people in the comments here mentioned Emacs, Google Docs and other tools as well.

Also, you can have ideas or want to make notes when reading a PDF or browsing some documentation, so your editor or terminal are not the only apps from where you want to initiate creating a new note.
Then what do you do when your parents die? And someone else is supposed to take care of your parents while they are taking care of you? At some point, people need to take care of themselves. Maybe some aren't ready at 18 to be out there on their own, but you need to take responsibility for your own life at some point.

On a related note, you should know that depression causes cognitive distortions. You should really take a look at this if you haven't seen it already: https://en.wikipedia.org/wiki/Beck%27s_cognitive_triad

Do you find people often disagree with your views on life? Is it possible that your reasoning is potentially being made on imperfect information since depression filters out all the positive aspects of everything?

>Maximising profit is not a neutral decision even if it has neutral intentions.

Complaining that for profit companies maximize profit makes about as much sense as complaining great white sharks eat meat. Both do what they were evolved for, both die rather quickly if they don't.

Perhaps we shouldn't put great white sharks in petting zoos. Perhaps we shouldn't put our children's well being into the hands of for profit companies.

Regarding the former, my ISP allows me to set forwarding email address. I could temporarily use these until X date or until they receive (a lot of) spam. Though all spam gets filtered anyway.

Regarding the latter, when they email you directly without the + you can be very strict. You could even apply whitelisting.
I'm a huge fan of the following essay. It provides a set of very rational, well considered and compelling arguments for less unit tests:

As you mentioned, you are far more happier sitting behind and building the product, maybe you could hire an intern for a few months who would be happy reaching out to people and try and get them to pay and if they don't, then understand why they are not doing so. Are you really solving a problem that exists? An intern with good people skills and empathy should be able to help. Though personally I was not sure what is the value add that a website for a small business would have over a facebook page.
We build websites and I think this is a good idea because many people don't need more. But I'm unsure if people would buy it directly (and with the price tag your competition is very big - squarespace, jimdo, wix, even normal wordpress). Maybe there should be a focus on web agencies, designers and developers which indirectly sell this to their clients and save themselves money and effort. This also aligns more with your character (instead of selling directly to SMEs / very similar to B2C which can be unpleasant).

Seems to be a good product for a freemium model. It can be beneficial for your career to have something which has success (in the sense that you have a lot of users) instead of focussing to make some money out of it. This can accelerate your career faster than making 200-500 bucks a month through subscriptions.

edit: I would try to sell it for you (I'm buying/selling websites), but I think it could be hard to find a satisfying price point without any revenue proofs.
Yes, if you've already written the tests, the tests will take no time to write. That doesn't mean they were free the first time around.

On a "warm" invocation, almost all the time goes into DOSBox + QBasic.

Not precise measurements but: on my MacBook Pro, running the QBasic interpreter from within DOSBox consistently takes about 1.5 seconds & running DOSBox + QBasic from the shell in "headless" mode takes about 2.4 seconds.

OpenWhisk also gives me the logs of the invocations, which include debug lines produced by DOSBox, and from the timestamps in those I can tell that invocations do typically spend >2s running DOSBox.
This comment from an earlier discussion here covers some of them: https://news.ycombinator.com/item?id=17185335

Basically, dep/glide do a bunch of stuff, including recursively parsing import statements because of How Go Works (tm). Other package managers don't, because they have lock files, and central repositories. Go expects you to just be able to throw a ton of raw code into your GOPATH and have it all magically fetched from github, which is super cool, but also very hard to do quickly, and not really something other languages are clamouring to support.

(A lot of attention has been focused on vgo's solver, and it is much faster, but the solver isn't what takes up all the time; the speedup from dep/glide to vgo seems to be almost entirely related to the changes in how dependencies are declared. Saving 10ms on a more efficient solver algorithm means nothing if the overall process is spending 12s grinding through slow disc and network access.)

And when you survey the language ecosystem, you see a lot of languages very enthusiastically committed to traditional package managers (with lock files) and centralised repositories. Cargo, composer, npm/yarn, bundler/ruby gems - recent history is full of languages happily moving in that direction. Go is an exception, and I don't see anyone actively copying that quirk any time soon.

It's also a beautiful design if you're into that.

I'm not suggesting that it can directly compete with a macbook in terms of graphics or processor but it's only slightly under for less than half the price.
Maybe in those cases, if the treatment, if it shows promise, should be given also to the people that were given placebo (after the study)
How does this compare to the other website builders e.g. Wix or Weebly, or the common standard for blogs, Wordpress? There are various means to cross-post from Wordpress etc.
I come from a family of 4 children, but there was a single child nonetheless because we're 3 boys close to each other in age, then a large gap, then a girl. My parents say that in the case of my sister some things were a lot harder because she'd be a lot more prone to being bored and needing entertainment or to being driven over to one of her friends' place. Whereas in the case of us boys all they'd have to do is set us loose in the backyard with a ball(or teach us a boardgame, etc...) and enjoy their peace and quiet until the next meal time.

I'm now experiencing this with my own children to some extent. We have 2 kids so far, a 4 year old boy and a 1 year(and a couple months) old girl. They both wake up around 6:30 in the morning. And whereas before that meant that I'd never get to sleep in past that time, now our son just gathers a bunch of toys, climbs into his sister's crib, and they play until like 8am before they finally get bored and start calling for us. So at least as far as mornings go, 2 kids has proven easier than 1(after that initial 6 months from hell period where you don't get any sleep at all that is)

Very great idea, and I think it can become more popular if there were more discussion-based websites.
If the e.g. scheduling code is messed up, and we find out 5 weeks in, then there is a lot of damage. We need to call all parties to review their schedules with them.

On the other hand if the code responsible for the styling of some menu is not working correct, the functionality may still work, and once we discover the bug we can simply fix it.

> rarely do I hear of code that doesn't need to work correctly.

So there are different grades. That's why I used the word maximum. The cost for these unit test should pay bank, even during the dev't phase, IHMO. There are often areas in a large code base for which this hold true, and often they can be identified as such beforehand; then writing these tests should be a priority.
Even if most browsers don't check, it takes just one single person to expose the whole operation. This provides a strong incentive to use compromised cert vendors only for the most important operations, instead of indiscriminately against everyone: each use of a counterfeit certificate risks "burning" the whole cert vendor.

And as you say, browsers today might not check these things (and checking CAA doesn't make much sense for a browser, it's intended to be checked by certificate issuers). But future browsers, browsers customized with some third-party extensions, or non-browsers might check.

Hi Radim!

To make it clear, I am not happy with the current state of reproducibility in AI. Yet, it is still better that in all disciplines I interacted with (quantum physics, mathematical psychology). There the standard prectice was to not include any code, even if the paper bases on it.

Vide my answer to "Why are papers without code but with results accepted?" (https://academia.stackexchange.com/questions/23237/why-are-p...).

So, I was so happy to see that in Deep Learninig a lot of code appears on GitHub (I am the most happy if it appears in different frameworks, implemented y different people).

Dirty code provides limited value. It's hard to learn from it, it's hard to re-use it, and its performance may depend on the phase of the Moon (and system setting, software versions, etc).
Yet, IMHO, is much better than no code.
It is not only about good faith, but about including all details. Some of them may seem unimportant (even to the author), yet crucial for the results.

The next level is resonably well written code, with clear environment setting (e.g. Dockerfile/requirements.txt), and the dataset. Otherwise it is hard to proof it against "on my environment it works":

> where the replication scores came out 62% instead of claimed 72%
Ethereum is novel and ambitious technology. In my mind, and I think in the minds of most in the community, scaling had always been the big, important challenge on the horizon - but it builds confidence to see just how far the devs (and community) have brought it till now. It's like everything is in place for that final push over the mountain.

The Espressini example seems to be offline, which isn't always a great indicator. Your Twitter link on the team page also goes to the wrong person (no underscore). I doubt these are hugely relevant, though :)

I think for me, I'm not sure I see the value between this and the FB page itself: if I've got an FB page, I probably want my clients to interact with me there. That's where I am, where I advertise, where I collect likes/etc. This feels like an interstitial between Facebook and my users: granted, it goes on my own domain, but frankly I could just buy a domain and have that forward to my Facebook page.

Your homepage is basically solution-oriented, but not really telling me what problem it solves.
Parent was downvoted but shouldn't be. A lot of people really seem to need to believe that Elon Musk designed the falcon rockets or the teslas. This is simply not the case.

What made SpaceX work is that he found most of the good people stuck in bad organisations already in the space sector, put them under one roof (which almost never happens in aerospace with it's goverment-funded pork-barrel contracts), and provided both the money and the will. Having both, rather than one-of, those last two things (the money and the will) are almost unheard of in aerospace anyway, and are a super-power. They gave the Tom Muellers of this world they space they need to do their work, and they had them co-located with the manufacturing, and they cared about manufacturing techniques, and they made a product. It probably was, and maybe still is, the nearest a company has come to taking Skunkwork's crown as an example of how aerospace engineering can be done right.

He likes to geek out, and he has vision, but he's a pusher of engineers rather than an engineer, and he sails very close to the wind with over-pushing his people. To the extent that any historical or fictional comparison is apt, he's more a Henry Ford than a Tony Stark.
... or privatised and all the data used commercially
>Reference implementations are not about performance, they are documentation. They are not supposed to be used for anything else but documentation.

That is valid for all H.262 , H.263, H.264 and H.265, as well as the up coming H.266 VVC. The current Av1 isn't a documentation. Nor it is a Reference Implementation in the regards of all MEPG codec. The AV1 is built on a working, professionally made libvpx encoder built on VP9.

>There is absolutely not reason assume that av1 is fundamentaly more power consuming that HEVC.

It definitely will be more complex, both encoding and decoding. Its fundamental complexity is much higher then HEVC, how far could they optimise so they are close to 5 - 10x of HEVC is a different story.
Offtopic. DLT is basically a marketing fraud. Both "permissioned" and "permissionless" DLT are packed into one term. Problem is - they are vastly different. Permissioned DLT is not interesting at all from technical and social point of view. We knew how to do them for a long long time. Openness, permissionless is the key innovation introduced with Bitcoin. "Permissioned blockchains" are just repackaged tech with lot of marketing sauce.
I understand the model, but nevertheless Whim points out it’s an introductory offer, so price raise is expected.
I'm going to admit that more than 10 years ago I wasn't so sure about global warming. Not an outright denier, just slightly sceptical, mainly because I felt there was a bit of mania surrounding it. But at the time I sought out a climate change scientist who sent me a few papers, which I read and was at least sold on the idea of CO2 levels and global temperatures rising, though with little conclusive evidence the two were connected by causation, although that was the most likely scenario.

More than 10 years on, climate change scientist's predictions have turned out to be terrifyingly correct, and I feel embarrassed for my previous naive scepticism. If now I meet a climate change denier/sceptic, I find this XKCD comic [1] is the most convincing way of communicating the problem, addressing both the idea of a recent ice age, and also the rate of change.

Would love to know why this gets downvotes. I'm merely reiterating studies on lifetime income and children expenses. Would love to know if I'm relying on wrong data (although the studies are pretty clear about lifetime income).
From my experience trusting a unit test instead of looking at things in the browser is a certain recipe for introducing bugs. Not sure if this is what you are advocating or if I misunderstood.
