Is it really 20% annotation error? I read it as 20% of the errors were detected. Errors could be some very small percent and of those that had error 20% were detected.

Devils advocate, Tinder ends with plenty of long term relationships. Ultimately much of founderdom is a crap shoot because you never know what your partner will turn into three years from now with money on the table. Truly obvious good founders who have lots of experience or proven connections are few and far between such that for the average startup rolling the dice may be just as effective as picking your best friend.
It's interesting to get more precise and accurate machines out of the ones came before.

Exploring Open-Toolchain FPGA HW Part 1
> is a program from December 2019 that "finds n-bit binary squares that are palindromic".

No dis-respect for Donald Knuth (who of course I found orders and orders of magnitude above programmers such as myself) and no dis-respect to people that found those types of programs interesting, but there are also programmers (like me) for whom those programs are just simple riddles, with almost no interest whatsoever.

They're like sudoku or crossroads, interesting and somehow intellectually stimulating but they don't help shape/change/modify the world around us. And I got hooked on programming when I realised how it could help me change the world around me and most of all how it could help me (and others) in trying to make sense on said world that surrounds us.

I was gifted a Hero 2018 when I left my last job. I use it for recording my cycle commute because I guess my death at the hands of a homicidal taxi driver should at least be recorded.

It comes with a basic set of features. 1080p video and some simple time lapse options. Pretty barebones.

Anyway it occasionally freezes when disconnected from the charger so I went and checked if there was a firmware update and it turns out that the Hero 2018 is the previous year's high end Hero 5 Black crippled by software. Someone put together a tool to load that camera's firmware onto it and now I have a 4K camera with GPS, a wide range of time-lapse and high frame rate features, stabilisation, wind noise reduction...

> Tinder ends with plenty of long term relationships

Sure, and some people go there looking for that. Most go there looking for short term enjoyment and possible long term relationships. That doesn't map onto the cofounder search. There is not much value in having the equivalent of "a couple dates" with at potential cofounder. And some people would actually see it as a negative, if they're worried (rightly or wrongfully) about their idea being stolen.

I can see why the author had difficulty publishing the article. If I didn't realise that he was talking about compactness I would have thought that he wasn't making sense.

The target audience is a nontrivial subset of people and it's difficult to optimise for everyone in the target audience. In any case I think that the real interesting thing here is not what lead to his observation. (Mathematicians have a tradition of not telling people what lead to their observations, for better or worse.) Rather, I think the mathematics behind this should be taken much further.

I guess it's off to the references.

Ask HN: How do you spend your break time?
Usually when I take a break I'll check HN, Twitter, text messages, YouTube, etc. I think these activities are fine on occasion when you need to just unwind for a bit and not worry about productivity. But when I follow the pomodoro technique, a 5 minute break every 25 minutes, that's almost 1.5 hours in a workday or around 16 days a year if you work 5 days a week. That's a lot of time. I'm interested to read what you spend your break time on that has more value. More value break activities I've thought of is trying to answer questions on Stack Exchange or read a book.

>By one estimate, the training time for AlphaGo cost $35 million [0]

How about XLNet which cost something like $30k-60k to train [1]? GPT-2 may have been around the same [2]
is estimated around the same, while thankfully BERT only costs about $7k[3], unless of course you're going to do any new hyperparameter tuning on their models which you of course will do on your own model. Who cares about apples-to-apples comparisons?

We're not talking about spending an extra couple hours and a little money on updated replication. We're talking about an immediate overhead of tens to hundreds of thousands of dollars per new paper.

Tasks are updated over time already to take issues into account, but not continuously as far as I know.

TAOCP sold more than 1 million copies over the years. Which doesn't make him Zuckerberg rich but wealthy enough to afford a house keeper if he wanted.
The odds ratio approach was backwards-looking, so it means "never developed symptoms [in a couple of weeks]".

Seems Iceland is testing a lot more than NYC and that their focused testing (which is still broader than NYC's overall testing) misses ~90% of cases.

Note that the Austrian study I've read shows that current infection as detected by RT-PCR is about 3x higher than present case count, which isn't quite the same thing I'm talking about with the antibody tests in Germany. If you're referring to something else, please share. In particular, no one knows the sensitivity for RT-PCR of asymptomatic people and it might be rather low--- it's not exactly wonderful in people who are quite sick and presumably shedding more virus.

I'm hoping in the next week or so we have antibody data from a couple of US jurisdictions, including the SF Bay Area. It can really inform policy.
> Places where models disagree with each other more often would be areas that I would want to target for error checking.

This is a great idea if your goal is to maximize the rate at which things you look at turn out to be errors. (On at least one side.)

But it's guaranteed to miss cases where every model makes the same inexplicable-to-the-human-eye mistake, and those cases would appear to be especially interesting.

>> You do realize that, yes, "most [doctors] are not trained in doing controlled trials" because they have another job...

Absolutely. It wasn't a criticism, just the way things are. For example, one doctor is claiming HCQ + zinc + antibiotic has treated over 700 covid-19 patients without a single death. I think it would be appropriate for someone to audit his records to see if that's true (was it even covid? or just some cold going around in his area?). If another doctor wanted to replicate his alleged success, I could easily see them using a slightly different protocol (skipping the zinc, using a different antibiotic, changing when or how much to administer, etc) and then claiming he's wrong when it doesn't work for them. That's just how a lot of people behave unless they've been trained otherwise.
NPS rangers tend to be fairly proddy, in my experience. Before all this started, I spent a fair amount of time photographing birds in national parks with a 200-500mm tele, and I've found it rare to encounter a ranger who doesn't remind me that commercial photography is forbidden there, on the assumption - in my case at least, the false assumption - that anyone with kit like mine must be a professional.
Yeah, we also though Zoom would do it, but sharing screen with a video works too bad.
Stripe's forward looking goals seem to be mostly about expanding and changing the nature of online commerce, rather than capturing the existing payment processing market.

This seems to be a recurring pattern in the more innovative online payment services. GoCardless is similarly trying to shift how people pay for things online away from the fragile and unreliable card networks.

Unfortunately, at least for some of us, the problems these services are solving are becoming secondary. The biggest pain points now, as a business selling services online from the UK, tend to be about regulatory compliance issues that increasingly conflict with clean, user-friendly payment processes and about the increasing complexity of global VAT/sales tax rules (and the ever more hostile rhetoric combined with often unrealistic demands from many governments in connection with the same).

I'm looking at setting up a new business at the moment, and our initial assumption is that we won't be using services like Stripe and GoCardless at all any more, even though I've built modestly successful businesses with them in the past. We just don't have time for all of the compliance and tax hassle in every country in the world where someone might buy from us, and while Stripe's new samples and guides have helped with showing how to get their new PSD2-friendly API to work, they also serve to show how horrifically complicated the once-simple process of charging a card online is now becoming. In the near future, I suspect this will push many of us into using marketplace or merchant-of-record arrangements and just outsourcing the whole shebang to businesses large enough to deal with those issues properly, who will no doubt take a larger cut of the revenues in return.

You'd think governments would have been solving these problems at an international level decades ago, but many of them aren't even following the general OECD guidelines they've theoretically agreed. It's bizarre that in 2020, it's actually becoming harder for an honest business to sell a decent product or service to a genuine customer online.
Thanks for the input! It's on our radar and we'll add it soon. We only have nights + weekends to work on this..

I think the submitted headline is wrong. The article says "we found annotation errors on more than 20% of images". Maybe dang could fix it.
Leaving the partition during a reset is fine if you hash all the contents of the partition and check it matches a known good factory config. If it doesn't, download whatever files are needed to make the hash match.

Androids file signatures stuff is so close to achieving this - I think they'll finally implement it within a year or two, and that will finally allow reclaiming space when built in apps are deleted or upgraded while keeping the ability to factory reset.
From what I understand, hand-grinding small mirrors is down to process as much as skill. Solid grinding compounds, once they start to wear, end up wearing themselves too. If you keep the pieces moving just so, you can eyeball a rough radius with the grinding material, and it will smooth itself out while smoothing the glass until they mate up.

Basically once you have a wheel with a high precision axle, you can make lots of curves or straight lines.

Sure you do. Some of those scenarios are vastly more likely than others. Kind of the definition of a 'wet blanket', to keep bringing up unlikely negative outcomes like they might really happen.

Yes, yes, they might happen. But the likely scenario is, with 1M people working on a dozen fronts, that modern intelligent educated humans will defeat this. Not on just one front, but on several simultaneously. In a couple of months we'll be planning exactly how we'll proceed.

Probably a cultural thing.

Debit card means you're responsible and take money out of low/zero interest checking account at the principal bank where we Germans hoard our money.

Credit card means you're on shaky financial ground, deal with credit card companies with their fine print, risk punitive overdraft charges, and have probably no idea if you have any money left.

Sadly, things are changing and many people seem to take on irresponsible loans (i.e. for anything except real estate).

Thunderbolt can be added to anything. There are Thunderbolt 3 AMD motherboards currently even, just only on desktop where it's borderline pointless.

The main thing is Intel's CPUs integrate a chunk of the thunderbolt 3 responsibility (which Ice Lake takes even further: https://www.anandtech.com/show/14514/examining-intels-ice-la... ). So it's an easy add-on for OEMs, which makes it more common & widespread as a result.

Also relevant being this is AMD's first time being in a premium laptop position in a long, long time. Just having AMD in a premium offering is itself a new scenario for OEMs.
need to check it out. thank you.
Agreed, my initial title is not accurate. It should say "finds errors in 20% of annotations".
Shape up: Reviving the pre-project
So I read through the whole landing page and I don’t really understand what this is. It sounds like it’s just another virtual private server? How is this different from getting a VPS on any hosting provider and remote desktoping into it? I guess since it’s paid by the hour rather than pay by month, but generally a service like this charges you for every hour your virtual machine exists, not just when it’s running. So unless you want all your data deleted you’re going to be paying longer-term anyway. Or maybe that’s not the case, they certainly don’t go into any detail to explain it one way or the other.
I personally think consideration of this apprach speaks of the technical range and sophistication of the practitioner. It is unusual, but we're in agreement that this is due mostly due to soft and orthogonal issues.

Making somebody crash in a dumb car is pretty hard if you want to do it in an undetectable manner with minor to no risk to yourself or anybody else.

Glitching an AI on the other hand e.g. by holding up a sign is less risky for yourself, and less detectable.
I think this idea actually has a better chance of working, for a couple reasons:

• There is less risk in starting the relationship. You're not divvying up shares in a company or even paying a fixed salary. The only thing you stand to lose is the time spent figuring out the comp structure

• Founders don't have to open up quite as much about the business, and worry that their idea will be stolen/copied. This is partly because founders seeking salespeople will be further along (alpha version or later), and partly because there's less of a fear that a salesperson will start a copycat company than an engineer (because of skills, not intrinsic honesty).

The question is; sub 1sec for who? A lot of people aren’t going to be loading that page over the same quality of network connection as your average hacker news reader.

Really depends on the side project. I'd pick C if writing low-level/kernel code, OCaml for language-processing tools, Python for scripting/ML/Algorithms. Go for distributed systems. It'll also depend on available libraries. Occasionally C++ if I need speed + data-structures. But most of the time, my side projects are just a pretext to learn something new, so I would happily pick up a new language.

As for the tools, I use VSCode that works well with all languages, and git (github/gitlab, probably gitlab). Then VMs or docker. And unix shell/bash.

1. Could I just provide a zipcode instead of sharing my browser location?

2. Could I check stores in aggregate? I'd rather discover which local business has the MOST openings and then register an account there, rather than getting to the end of the shopping experience and waiting.
