Ask HN: Ideas for startups to solve the plastics & packaging pollution problem?
I'm wondering if solving the plastics pollution problem represents an opportunity for startups to create businesses.

Does anyone have any ideas for a startup that could help solve this problem that is plaguing the world?
> Academic performance is mostly a disqualifier to figure out if someone would be successful enough

Really?
I do wonder how many lists I am on already.
I don't get why you need to evaluate based on personality to get admission into an educational institution. Just doesn't make sense.

"Harvard’s lawyers will soon tell the highest court in the land that Casey Pedrick’s Asian students are less respected because they are less likable, less courageous, and less kind than all other applicants."

And that's how you lose out on the best.
> I think he took it with more grace than I deserved.

You mean he gathered all of his students, colleagues, and superiors; officially admitted to faking knowledge where there was none, and solemnly apologized, promising never again to teach things he doesn't understand?

I somehow doubt it, even though teaching nonsense to eager youth from the position of authority is an offense damn close to sexual molestation of minors. Dealing with subtly (or not so subtly) twisted minds, and holes (and lies) in knowledge, of the corrupted students happens years later and is someone else's problem, but it's all caused by teachers like this. I don't see anything graceful in it, at all.
This is a pathetic comment.

Not if the jar pays you an interest rate. I'm being facetious.

But my point is calories out will vary depending on calories in. You can eat 2000 calories of carbs 1 day and 2000 calories of protein the next... turns out your calories out will be higher when you eat protein because your metabolism increases. This isn't physics. This is nutrition. And its still not fully understood IMHO.
Success in business can also be defined as creating a sustainable entity that builds infrastructure/buildings, provides services, and employs people. The local Ben Franklin crafts and Ace Hardware franchisee in my hometown would qualify by that definition, though his personal profit may be higher if he had instead liquidated his family's holdings and put it all in an index fund.

If you define "successful businessman" strictly by comparative potential personal profit, that would rule out a great many people who have found happiness and decent profit in what they've built, and restrict qualifiers to the idle rich and a few unicorns. That's a break from how the word "success" is used in all other contexts.

Arguably also the more boring use of SDR; at least for me the interesting bits come from the ability to (de)modulate, filter, process and otherwise mangle signals in a way that would not be feasible with traditional radios. Using SDR to "just" listen in on old modes and bands seems like a waste in comparison.
Why would you start with a circular definition? You can't use a word in it's own definition!

Hi John,

Greetings from Anton, CEO and co-founder at YouTeam, a marketplace for hiring offshore development talent.

Lately, we’ve been researching the topic everyone wants to know more about but fears to ask: salaries in blockchain. Did you know that according to public sources the average blockchain developer salary in the US equals $95,545? Would you agree with this or do you think it is actually way higher? We researched the salaries in the most popular cities in the US and right now discussing them on Hacker News.

Help us gather fresh opinions, find more reliable sources and better data!

Join the conversation here: https://news.ycombinator.com/item?id=17403348

Best,
Anton Mishchenko

Completely have to agree. YouTube has so much content, far more than Spotify, Vimeo and everybody else in the space, which is why I use it. But the recommendations are an offense. YT is only good at 'recommending' stuff I already watched or listened to. What's the point?

Translate can be useful at times...like once a year when I want to comprehend a Japanese website, usually I close the tab after 2 minutes.

I used GMail for many years and still do to some degree but I'm moving to a different mail provider. GMail's spam filter is great!

Not sure, since 2 years it became acceptable to make no difference between ML and AI. ML appears smart because of bizillions of training samples and I feel very impressed when I hear of that. But yeah, at the end of the day it doesn't have exactly the biggest impact on me... ;)
tl;dr the only reason to care about SNI in TLS 1.3 is if you are a privacy freak. It's not a security concern.

Because the postmodernist view is based on "identity" - race, gender, ethnicity - not academic achievement or merit. They see any system that doesn't produce the outcomes they prefer as inherently racist and bigoted.
Consider the same rationale for security: let's allow any user to do anything with our ecosystem, unless we know them to be malevolent.

I'd argue that the human body is a lot more worthy of defending than a cloud platform. I'm totally fine with a whitelist model.

Cannabis was a fluke; legislation was pushed through by a political opportunist despite the AMA pointing out that there was no evidence of harm caused by cannabis. The regulation model in itself is fine, we just need to take the people out of the decision making. :-)
Smart move for Spotify, foreboding news for Genius.

This is also a cautionary lesson for founders about raising at inflated valuations--Genius's series B raise at close to a $1B post-money val will make it more difficult for them to exit with an acquisition.

(In fairness, they completed that round with the intent of "annotating the internet", not becoming the music content platform they've since pivoted to.)
Analysis: Interest in Cryptocurrencies Is “Surprisingly” High
Harvard's admissions policies do not have discrimination as a deliberate goal. Arguments about them are typically about how they can result in effective discrimination or unfairness of some sort.

Soviet discrimination was straight up just that.
A few interesting things about SDR and the kind of tinkering and experimentation one can do:

- in amateur radio, SDR is starting to dominate new commercial designs, but has not yet overtaken the superhet.

- you can buy a low end SDR (rtlsdr) for $20 or a better one for $120 (sdrplay) or a high end one that transmits for $2K (flexradio)

- Ettus hardware is great if you have the dollars and only care about VHF/UHF

- if you want to play with the concepts without buying hardware, just learn DSP.

- there are many interesting applications that are now fairly affordable to build that used to require massive budgets (due to cheaper FPGAs)

I've personally had no problems with them (save for one near heart-attack where I lost multiple keys), but I'd suggest looking at their documentation too [1].

It's also worth noting that you don't need to store any keys in their cloud storage, encrypted or otherwise--but you can for convenience.

The very idea that anyone could understand a person's personality or character from an essay and 45 minute interview is laughable. On top of this, even trained professionals demonstrate subconscious racial biases in everyday life. This has been confirmed in several psychology studies. It's perfectly valid to question the value of a subjective personality assessment. It opens the door to stereotype-fitting and confirmation bias. I'd also challenge the admissions committee to really observe the way Asian-americans, particularly Asian-american males, are treated on campus at Harvard. It's bizarre and surprising. They're treated with the casual dismissiveness formerly reserved for 1950s housewives. I can't imagine that this attitude doesn't track all the way back through the admissions process.
This drove me insane with poorly maintained NYC taxis and buses too.
How about the preferences panel?
Anecdotally they also chased after a consultancy using mitre.com and forced them to give up their domain. The founders had gone to MIT and Rice University and were in a completely different sector but MITRE didn't care.
The interviewer would still know the race, we just wouldn't be able to analyse the results for bias (unless working off name alone).
Why Commodore Failed with Commodore's David John Pleasance and Trevor Dickinson
I'm surprised Spotify hasn't broken into podcasts yet (or have they?). The platform works for it, and it feels like a natural transition to go from listening to music to listening to a podcast without leaving the platform.

What's the point of your comment? If you can do the same thing without JavaScript or with, the implementation that doesn't use JavaScript is categorically preferable.
the many problems in the study of consciousness are well documented (hence why this thread begins with "toward a...") -- so of course it must be studied in an interdisciplinary manner (what cognitive science attempts to do). can somebody more familiar with this work in particular explain what it contributes, or summarize the idea behind MICS for us?
You asked "Says who?"

I provided some examples.

Explore as much as you can without the rebel fleet catching up to you.

Generally speaking, you actually want to pick as many fights as possible. The game implies that you're supposed to be a peaceful and heroic Star Trek style Federation and that's not what it actually rewards at all.

The ship upgrades that are always available are more important than stuff you can buy in shops, even though the shop items are more interesting. An extra dot in shields pays for itself in a hurry. You'll eventually need other stuff, and there are multiple load-outs that work, but lots of multi-hit weapons with low power requirements is the simplest winning setup.

Those are the common misconceptions. The game doesn't actually do a great job of communicating how to play it well.

As a commenter pointed out, these things are always handled by insurance companies.

Is this known by experience, reliable source, or just something everyone "knows"? Because when I was a mechanic (albeit some 25 years ago), if a car falls off the lift, best be on the horn with the shop's insurance company. Hey, the car was in fine shape when I brought it in, don't be telling me to call my insurance company.

But things might have changed in the time intervening. Regardless, it's poor form for Tesla to just immediately lawyer up.

It was definitely an explicit goal. There's a great book on the topic: https://www.amazon.com/The-Chosen-Admission-Exclusion-Prince...

Here's a quote from a summary:

> At one point, [Harvard President] Lowell wrote to a Harvard philosophy professor to explain that enrolling a high number of Jewish students would "ruin the college" by causing elite Protestant students to attend other schools, according to Karabel's book. Harvard would be ruined "not because Jews of bad character have come; but the result follows from the coming in large numbers of Jews of any kind, save those few who mingle readily with the rest of the undergraduate body," Lowell wrote in the letter.

The whole POTS system is archaic and ripe for abuse (which we see with telemarketers able to spoof their numbers).

IMHO the solution would be a calling system where spoofing is difficult/not allowed.

> "My numerous calls to Management were never returned."

> "They completely disregarded that I am a CONSUMER and deserve answers."

This is where I start suspecting there's more to the story than the author indicates. This kind of entitled "the customer is always right" attitude is exactly how you get treated in a legalistic way.

Of course Tesla should apologize for their mistake and make it right, but if the customer was threatening or rude to their employees they have every reason to give a cool response.

Worse than a bad customer is the companies that enable their shitty behavior. I hope Tesla sides with its good employees over bad customers, if that is the case here.
have to agree i dont follow the logic in the parent post. simple refutation: there can be conscious beings which are not self aware (ex. somebody on ketamine).
I just did a cursory review of some papers, and it seems like cannabis can induce psychosis. It looks like there's somewhere around 1.5-2.5x increased chance of psychosis diagnosis for cannabis consumers, although age and family history of schizophrenia matter.

From the NIH site on psychosis[0], about 3% of the US population in their lifetime[1]. About 100k adolescents annually have an episode.

For comparison, alcohol induced psychosis is common. Dependent alcoholics men face an 8x increase in risk; women see a 3x increase.[2]

> Man, that wasn't minimalism, _the computers really were small._

Yes, they were. But it was more than that. The machines were very diverse. Several very different video card options were all in wide use and to make them work efficiently meant low level frame buffer work. Pointers were rare and weird, and again, diverse; bus mice, serial mice and other stuff. Writing a GUI compatible with all the permutations of PC hardware while being simultaneously efficient enough to run from floppies was possible with difficulty, but what value would it have provided? These were 16 bit machines with either no or extremely limited (286) MMUs; just how many processes were you going to be multitasking with your 512K of MMU-less RAM?

DOS was just a program loader, and being just a program loader it was perfectly suited to the PC market. You bought a system with the 'adapter' cards you needed, booted DOS and let some program take over the system, be that Word Perfect, Paradox, Lotus 123 or whatever. That was the real, day to day use case for the PC. An advanced user with a 'fast' disk could bounce between programs in a few seconds and that was entirely sufficient for the vast bulk of PC users. It's also not dissimilar to the contemporary phone/tablet use case.

And I don't remember anyone getting too hung up on the C:> prompt. They either acquired the clues needed to run a few commands or had someone make a .BAT file to kick off their program.

There were certainly contemporaries with compelling UIs, but they invariably cost more and had a vastly smaller catalog of software.
It is a New Yorker article - it isn't trying to make a singular point and convince you of it... it is storytelling about some interesting work being done.

As far as you not having heard of hypersensitivity, that isn't a shock. I first heard of it as a diagnosis from the Mayo clinic, after my local docs weren't able to find anything wrong with me. And they said that many doctors aren't yet familiar with it yet. It is a fairly new area of research.

But again, that circles back to the article -- it talked of how their findings support the effectiveness of cognitive behavioral therapy for chronic pain. (Also what the Mayo clinic recommended, BTW.) I found much of the article resonated well with my experiences of chronic pain, and I am hopeful that someday research such as this will be able to find reasonable treatments that dial the sensitivity back down to normal for people with abnormal pain responses.

Another term you can research if you really want to dig into this is "central sensitization".
I think execution policies will prove too abstract and coarse in their current state, so won't be very useful.

Normally it's good to have pleasant abstractions and generic functions. But execution policies are there for speed and speed alone: if they don't make things faster, they've failed. So in this case it's worth tolerating a more awkward API to achieve better performance.

The C++17 parallelism interface is more or less to declare "this loop can be parallelized," which does not provide enough information to the scheduler. You need to express properties of the algorithm, such as its optimal chunk size. (In the future perhaps those properties will enter into the execution policy as e.g. constructor parameters.)

Second, passing in callbacks which receive one or two elements at a time is too granular. You are at the mercy of the compiler to optimize these. A better approach would be for the callbacks to receive a pair of iterators and allow the user to drive the loop. This makes it easier to avoid accidental indirections, failed alias analysis or inlining, etc.

Intel's TBB will continue to be more useful here.
Ask HN: Is Deep Learning reasonable for a 1 man team?
I'll explain the problem:

>I need to collect store prices(and item name), but this requires taking a photo

>This needs to be typed and lined up to internet data that has some flaws.

-The names are incorrect (fuzzy text is correct only 90% of the time)

-Sometimes there are combinations/deals that require 4-8x as many extra combinations. I believe this needs to be figured out by a person.

Everything else is automated after that.

Currently using python, but I have 10 years of programming experience, and working on a few other unrelated projects in other languages.

This idea to use Deep Learning seemed like such a weird buzzword that I blew it off. Looking into it, it might???? be reasonable?

Using blockchains to solve issues in trade finance
Harvard has around 1000 admissions spots in any year. I think there are roughly 30,000 people who score a SAT 2200+ in a given year. Say half of those a have A level GPA. At that point there's more significant non-academic differences, than academic differences.
Good question.

The application had grown and ran in production over a number of years using NFS for storage before it was moved into AWS, so this probably naturally steered devs away from trying to use the shared file storage as a high performance cache (eg they might try it, and find it to be slow, and figure out a different way of doing whatever they needed to do, probably using the db).

Our usage pattern for NFS did not generally involve needing to read or write many small tiny files with any degree of performance. E.g. we might need to do reads/writes of dozens of files, each of a few mb in a process, with the overall running time of the process being largely governed by our DB performance / patches of poorly written algorithmic code running in a slow scripting language. Amdahl's law - for us making the NFS access go infinitely fast or 5x slower hardly changes the overall total process execution time.

I can certainly appreciate that EFS is an abysmally slow for dealing with large numbers of reads/ writes of tiny files, in another part of the system one of my colleagues set up a read only cache of a large number of tiny files in EFS, due to the per-file write latency it took around a week to load in < 100gb of data.
I get the joke, but how secure are passwords these days? There are cameras everywhere; if you type your password in public there's a reasonable chance a camera will pick it up; it wouldn't seem impossible to automate recognition of which keys you are pressing.
Anyway, why would anybody standardize this at all? Too many ways to do it and each one sucks because of race conditions. Any program that needs such a feature should just write the 10-20 lines version that it deems best.

There will hardly be any project that needs to know the "recursive file size" that is also too small to be able to afford this extra work.

Ok, but maybe I'm missing something here: Why parallel? Is there any benefit?
I disagree with your paraphrase. Why not cite a specific quote or passage from Dennett where he makes such a ridiculous claim.
