It is a matter of definitions. Here is a review: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6234835/.

"The FA framework for understanding obesity is the notion that highly processed 'hyperpalatable' foods have hijacked the reward centers in the brain thus impairing the decision-making process, similar to drugs of abuse."

"Finally, there is strong evidence of the existence of sugar addiction, both at preclinical and clinical level. Our model has demonstrated that five out of eleven criteria for SUD are met, specifically: use of larger amounts and for longer than intended, craving, hazardous use, tolerance, and withdrawal. From an evolutionary perspective, we must consider addiction as a normal trait that permitted humans to survive primitive conditions when food was scarce. As we evolved culturally, the neural circuits involved in addictive behaviors became dysfunctional and instead of helping us survive they are in fact compromising our health."

This is an interesting take on the technology of vestibular stimulation.

Something to keep in mind is that this technology has been around for a while in the medical field for treatment of balance disorders.

Also - I recall back in the very early 2000s there was a company that came out with a vestibular stimulation system for VR use - the idea was to induce the feeling of motion. You could plug it into your computer, and it had a Windows API that you could control it with.

They were still in a development phase; you could purchase a device and the API for developing with - it wasn't a retail product at the time. Ultimately, the dot-com crash took them out and they disappeared before they really got off the ground (also, VR was in it's "winter" - that didn't help).
WKWebView now does allow that, in a roundabout way, through WKURLSchemeHandler.
Does this control for benefit from social anxiety reduction?
Or benefit from experiences which wouldn't have even begun to occur (due to social anxiety)?

"The only safe level of driving is 0" and yet its trivially clear that someone who chooses not to drive due to fear of the risks, may experience stress and other factors equal to or outweighing the risks that would result from driving.

I'd guess a more accurate statement would be that there is no risk-free level of alcohol consumption. Because, ultimately, there isn't a safe level of being alive.

When your metric of "safety" applies similarly to what makes life even worth living at all, and decries life "unsafe", it doesn't seem very useful.

FWIW, we definitely looked at a dual-license style approach.

One thing that I keep pointing out is that the Apache provides a way for the license to be self-executing. This is really cool (although also one source of objections) and IMO super important for an Open Source project like LLVM. It avoids the need for us to force every person who ever posts a patch to sign a legal agreement before we incorporate the patch because the Apache license itself handles those kinds of issues.

Unfortunately, we wouldn't get that w/ a dual-license approach. And we would add a lot of complications due to the duality. =/

for me it would be an inordinately expensive use of my time, but for you?

at any rate, both budgets are not infinite, and it's infuriating to hear the described as such.
These types of studies (correlate [common behaviour] with [common health issue(s)] will "discover" whatever the prevailing opinion is of the day.

The structure of the statistical models and what features get included is totally arbitrary, so they just play with it until the "right" result appears. In some cases you can even code male = 1, female = 0 and see (for example) alcohol is positively correlated with a health issue, but then reverse it to be male = 0, female = 1 and see alcohol is negatively correlated (see a simple example in [1]) Totally arbitrary.

Yes. Let's go back even further to six-year-olds making things up in a backyard. That's improv! There's a sense of play, a sense that you just need to add one thing or less to what's already there, and a sense that no one's in charge. Improv.

And some forms of role playing games resemble improv, but also not all. :)

There's definitely overlap!
Ask HN: Freelancers quoting large jobs
Hello fellow freelancers of HN. One thing that I always struggle with is estimates/quotes for large unwieldy projects. In particular, there are 2 opposing forces:

Force 1: Even for very well-defined projects, it's extremely difficult to accurately predict how long a large project will take. Not to mention all the minor additions and adjustments that will be made along the way. It seems like giving a hard quote is next to impossible and the way to go is an estimate for hourly work.

Force 2: Charging hourly. I typically avoid charging hourly, instead giving quotes based on my internal rate of $100/hr. Although charging hourly can be preferable, see issue 1, I feel that most clients would balk at such an hourly rate and would prefer to pay some offshore developers $30/hr and hope for the best. On the other hand, if I quote $10,000 for a job that's expected to take 100 hours, they will generally feel the quote is fair.

How do you go about quoting/estimating large projects?
I think I know what you mean when you say "consensus" here, but that's not what "consensus" really means. Perhaps you want a word more like "majority".
Yeah I worded that in an odd way. What I meant to imply was "it's insane that they didn't reach out to the SICP"

One aspect is speed.

Eat white sugar you will quickly get an energy boost but whatever cannot be used will be stored.

Eat a complex carb and it requires more steps to breakdown. That allows for a slower release of energy and less of a need to store.

The digestive system is a pipeline of processes.
My similar thought... isn't this an argument to disarm police officers? If their brains turn them into killers, take away the tool they use to commit the killing. Police isn't even one of the top-10 most dangerous jobs - they're beaten out by auto service supervisors (not even the guy with the wrench!) and airline pilots.
As it has done multiple times previously. I anxiously await reading why this time is "different", just like all the previous times.
Fascinating summary, but the comments got really nasty with people throwing around some pretty cruel terms for women. :|
There have been thousands of papers and many books written on the subject of using machine learning for time series forecasting and an unknown amount of money traded/invested with it. Most of them cast trading as a time series forecasting problem where performance is measured by mean square error. They usually then assume that would lead to profitable trading.

You don't get to define what "modern machine learning" is any more than I do.

The application of complex models to higher-dimensional domains have problems of their own. Both the successes and failures are worth writing and thinking about.

The post is an important reminder about simplicity and complexity in modeling. That's why I submitted it.
The massive CO2 emitter you may not know about
I don't think you can draw meaningful conclusions from a self-enforced system like Weight Watchers either though.

That's a generalization. Certain areas of operation had different rules of engagement, which also changed over time. As a base though, if you could prove hostile intent, you were cleared for the use of deadly force.
What, fixing pollution is cheaper than not fixing pollution, so we should keep polluting as much as we want? And because the USA is in the privileged position to avoid disaster, it should do nothing to prevent that to happen to others? Is this all we are?
Yes, this. Any driving is unsafe. Any life living is unsafe.
I know you probably exaggerated, but isn't causing so many feedback loops still the sign of a bad programmer?

I wouldn't trust someone to deliver quality software who produces multiple syntax and multiple runtime errors while coding, especially when modern IDE's fix typos on the fly? What about all the runtime errors he didn't test for?

Is that flow really that common?

Sure, I cause errors all the time, but my workflow includes a compile time error maybe once in 2 trys and an obviously fixable runtime error once in maybe 10 times. Sure there are these countless of edgecase errors I don't even know about, but that's not the thing catchable with this workflow and I wonder if someone with that workflow, who misses the obvious, does miss even more edgecases.

Also don't a lot of tech companies require (mostly) correct whiteboard coding exactly because of this for quite some time?
The word he used was "a t-shirt that would be an _analog_."
>just a pause

Exactly. It's the same tactic employed with various authoritarian measures such as the DMCA, TPP, SOPA, etc. Unpalatable to the public is a temporary condition. They overplayed their hand this time, but corporations are slaves to the inexorable demands of "shareholder value", and those who stand to profit will ratchet up the pressure, notch by notch. This will be back in a year, and then a year hence, and by the Nth exposure the public will have been sufficiently desensitized to it.

FWIW, if I had to pick the "biggest differences from MIPS" in RISC-V, it wouldn't be the fact that MUL works on GPRs.

More important is the lack of a branch delay slot (i.e. it doesn't bake in a particular pipeline stage design into the ISA), and the existence of hardware paging (MIPS tried to cheat here by letting software handle page faults, and in hindsight made a poor decision).
What about the first algorithm for back-propagating neural networks? I can't remember who did that but I am sure someone on HN will remember. When Minsky's "Perceptrons" was written there were all these problems with neural networks that back-propagation solved. That seems like kind of a big deal. It also seems like a lot deep learning is built off of or related to that work.*

People are obviously born with various IQ levels, right?

Doesn't it stand to reason that people are born with certain levels of willpower about food (or in general)?

Show HN: Qri, a free and open source distributed dataset versioning tool
I wanted to make you all aware of the latest release of Qri -pronounced ‘query’- (0.6.1), a free & open-source dataset version control system / network for finding, collaborating on & publishing open datasets on IPFS.

We’re finally ready to recruit users (crash test smarties) to test drive qri & let us know what they love / don’t love / what’s broken. You likely have questions about qri. Hope this helps:

Qri tackles four common data problems:
- Discovery: Can I find data I’m looking for?
- Trust: Can I trust what I’ve found?
- Friction: Can I make this work with my other stuff?
- Sync: How do I h&le changes in data?

Because qri is global & content-addressed, adding data to qri also checks the entire network to see if someone has added it before. Every change on qri is associated with a peer, creating an audit-able trail you can use to quickly see what has changed & who changed it.

All datasets on qri are automatically described at the time of ingest using a flexible schema that makes data naturally inter-operate. Qri comes with tools to turn all datasets on the network into a JSON API with a single command. Finally, all changes in qri are tracked & synced. All data on qri is public, & discoverable by anyone on the network once you hit publish.

Qri is still in its SUPER early stages, so it will be buggy, offer little guidance/help within the app. That’s what our team is here for.

How to Download: https://qri.io/download/

For now, you’ll need a Mac to use the front-end app (windows support coming). Scroll down the download page to see links to command line tools.

Getting started:
- Documents: https://qri.io/docs/
- Tutorials: https://qri.io/docs/tutorials/
- Qri Demos: https://www.youtube.com/channel/UC7E3_hURgFO2mVCLDwPSyOQ

Thank you so much!
> The second part of the criticism is that capitalism is a class society

The modern middle-class society of the present day would quite simply be utterly unrecognizable to 19th-c. theorists of "capitalism [as] a class society". In fact, they would find that most, if not all, of the policy goals that they originally set for themselves have been achieved, in a market economy! The Chinese leadership understands this quite well, BTW; the above consideration plays a significant role in their understanding of what a "socialism with Chinese characteristics" should look like.
Nice spin job. The owner tried to cheat and got caught.

Calories works if you do it, but doing so requires an unrealistic amount of willpower.
Taxing bad behavior often comes off as regressive, as are laws that would "require reuse". But the measures do work. If there are ways to encourage the good behavior without imposing financially-punitive burdens (which adversely affect the ones who value each cent more), they should be pursued instead.
So does sharpening your knife.
Software licensing is not necessarily related to contract law. Many software licenses do not fully qualify as contracts, because they are just a grant subject to qualification, rather than an (assumed) agreement between parties about terms of exchange or something to that effect.

I'm not entirely sure how patent grant drags in contract law, though. It might be the fact that it implies reciprocal patent grants. You might have to ask a lawyer for the distinguishing issue here.
Like the dot com bubble, and here we are today bigger, better and stronger. Think in terms of a public trading vehicle that enables anyone to raise capital in a global marketplace. Either real value gets translated to that vehicle or it does not.
>> All types of regulation are important and good, for the reason stated in first sentence

Come on. Absolutist positions like that are just wrong and bad for level headed discussion. Some regulation is good, and some is bad. We should be critical of government policy right? Hasn't history shown us that good intentions does not always lead to good results? We need our critics, just like developers need qa.

I think it's not possible conclude on optimality without firmly understanding the specific goals.

The articles says 'But the aim is usually to diversify risk, not concentrate power, by taking capital from the original family business and putting it into a widely spread portfolio.'

It uses the word 'usually' and it's also a blanket that's trying to generalize all these parties, while in a reality that may not be true.

Here are 3 constructed but plausible goals one may have:
1) Make 100% sure that you remain wealthy (make almost nothing but never lose anything)
2) 9-in-10 chance to do worse than SP500 index, but 1-in-10 chance to get 'literally take over the world' rich
3) Investing in causes that seem good for the world a la green energy, tesla motors, etc

As a counter example, I present cases of lottery winners who go broke. There are multiple documented cases of 10+ million and 100+ million winners who lose the majority of their wealth.

Funny, I would have gone bananas over this a couple years ago. Now, its mix between disappointment and but still support. MIPS exists and will continue to exist, its far to large to ever go away so it is good that it will open up and eventually we can remove property architectures from the market.

I just hope they really commit to that strategy. Remember Docker was once a failing PaaS company who released their tech as open source.
What's a common-case VPN problem, the kind that (say) 3 out of 5 company or personal VPN users would have, that aren't well addressed by Wireguard, other than lack of Windows support?
What organisation or person is not biased?
Wireguard works just fine on macOS.
I'm sure police officers receive training to that end as well

You would be mistaken in that assumption. Police in the US receive a fraction of the training provided to their counterparts in Germany and the UK. This is across the board, all types of training. They receive even less deescalation training, and in fact sometimes receive the exact opposite (training akin to "police as warrior").
Junk food cravings linked to lack of sleep, study suggests
I like both.

The problem I find with surface level knowledge is you make a lot of mistakes. When I have a surface level knowledge of a piece of tech and make a decision based upon that, then talk to someone with deep knowledge it's pretty common for them to say "why didn't you just do XYZ, it's easier/more robust".

Ultimately you can produce OK or even sometimes good solutions to problems but not great ones, unless you have direct access to people that know more than you.

This becomes even more pronounced when different pieces of tech can be combined with eachother.
>People who don't trust each other don't engage in trade.

You are going to need one hell of a citation for that claim, or you are using some new definition of 'trust' that I have not previously encountered.
What terrible, one-sided reporting this is. There's not even an attempt to present anything other than the voice of conservative preservationists.
It does pertain to individual tax payers. Tax payers can either pay ordinary income on dividends or capital gains tax on the sale of share with increased value.

Even better is that as long as the shareholder holds, they have increased value, but can defer taxes.
I've read this explanation (two equivalent choices, one is taxed higher than the other) so many times, but I can't believe there's no downside to stock buybacks. Something about it just feels very wasteful, like picking the fruits of a tree just to grind them into compost for the soil under the same tree.
Right. Can you do this is in the US?
When I mentioned "multiple vendors," I was talking about hardware implementations that have actually shipped.

I've been looking for RISC-V chips that I can buy right now, and from what I can tell, there are only a handful. Two from SiFive (the E310 embedded processor, and U540 supervisor mode/Linux capable processor), one from GreenWaves (the GAP8). Turns out since I last looked (around the beginning of October) it looks like the Kendryte K210 has been released, also available in the Sipeed M1 module (https://www.cnx-software.com/2018/10/22/sipeed-m1-risc-v-com...). Anyhow, that makes 3 vendors shipping hardware implementations.

It's possible there are other special purpose chips not widely available for sale, or not advertised to English speaking customers, but I haven't found much evidence of them.

There certainly are a lot of RISC-V projects under way, which was what I was referring to by "that likely means that there are a number of others where it's fairly far in the pipeline." I think the "hundreds" from the article you quote is about total number of projects, not total number of vendors.

Some of these are just academic projects, some are multiple projects at the same vendor, and so on. I wouldn't be surprised if it was dozens of vendors that have projects at various stages of completion, however. I can imagine we'll be seeing a lot of releases over the next couple of years.

And there are a number of cores you can run on FPGAs, from high-end cores like BOOM that can be run on big expensive Xilinx FPGAs (or on Amazon's cloud FPGAs), to low-end like PicoRV32 that you can run on a $5 Lattice ICE FPGA.
