Thanks for giving PySceneDetect a try. Can you share what you're using as the command line arguments?

For detecting fades-to-black, you want to make sure that you're using the detect-threshold command (not detect-content). For example:

scenedetect -i somevideo.mp4 detect-threshold -t 12 list-scenes

Where -t specifies the threshold to use (the default being a value of 12). Full documentation for the detect-threshold command:

I guarantee that it is possible to write any of these features in traditional HTML, CSS, and JavaScript without relying on today's frameworks or build infrastructure. I know this because even the most advanced build pipeline in the world must eventually compile down to traditional HTML, CSS, and JavaScript; that's all browsers run, no matter how many layers you add to try to abstract yourself away from it. I also know this because websites existed that had these features prior to React becoming popular.

Ask HN: How to invite owners to talk about things they would like to automate?
Hello,
I am a software engineer and I work as a freelancer mainly in business automation field.

I did a few applications which helped my clients to save a lot of money (literally a lot of money).

The problem is that I am probably the worst seller in the world so for me it is not a piece of cake to find a client.
Well, stop.

I do not event want to find a client, I just want to get information from business owner about things they would want to automate in their companies.

I have a very detailed list of over 3 million companies in my country - I have information about owners (for example name, email address, phone) and their companies (for example name, address, industry, registration date).

I tried to send an email with a simple question - would You like to speed up or completely automate any task in Your company?

I sent about 10 000 emails and I managed to get literally one lead - one man sent me his phone number and asked for a call.

As You see result of my campaign is a disaster. I wonder if email marketing is a good idea in my situation so I am looking for other ways to get information about things that business owners would like to automate in a specific industries.

Could You please share Your thoughts with me?

Do You have any ideas how I can improve my actions in order to get answers to my questions?

Thank You very much and have a nice day!

Thanks for just listing these out. I have worked on quantum secret sharing of the SSS type during my PhD. In QSS, the secret is not a bit-string, but a ordered set of qubits in some state.

Now, I am thinking whether there exists quantum analogs of these generalized classical secret sharing tasks you have listed.
How NOT to write more tests but have better tests
That interpretation of the criticism text is at best wishful thinking and at worst willful ignorance. Take off the rose colored glasses and read it again - there are several fundamental problems brought up.
It is a big supermarket thing moreso than a city thing. It’s a big part of the Whole Foods strategy, and an increasing part of Safeway/Ralph’s/etc. They have an increasing amount of hot food that you can take away. Walmart in the “country” didn’t, I don’t know if that’s a Walmart thing or a country thing (they did have a subway in-store).
This depends on the tier you decide to go with. IMO cheap glasses and cheap watches have similar pricing tactics...high end is a delicate dance between get what you pay for and status. Also keep in mind that you are paying for the opportunity / lucky chance of repair when the item is busted.

So, never. Or, more accurately, in about 20 years when "clicking" becomes an anachronism and someone will make this comment except it'll be: "s/taps/clicks and this has been going on for half a century"

> The National Highway Traffic Safety Administration (NHTSA) sent Elon Musk a cease-and-desist letter last October over “misleading statements” Tesla made about the Model 3’s safety. The agency also asked the Federal Trade Commission to investigate whether the statements “constitute[d] unfair or deceptive acts or practices.”[1]

You seem to be the one making the bolder claim -- that the NHTSA is either lying or wrong about their assessment of Tesla's marketing.

Since you're making the bolder claim, the onus is on you to provide some evidence, instead of making an unsubstantiated statement and childishly waving away your responsibility to back it up.

This is not an alternative to Markdown in any shape or form. Markdown resembles plain text and can be easily parsed by anyone without syntax highlighting, a Markdown → visual format compiler, or prior knowledge of the format; moreover, Markdown is meant to be quick to type without wondering about the intricacies of the output format.

This thing is anything but. You need to know the keywords and type them out all the time, you can’t use it in an e-mail because your readers won’t understand you, and if you like trees so much, just write regular HTML — or a “simplified” HTML format like Pug — and call it a day.

Fridges have a need to be cool 24/7, but not run 24/7. It's quite remarkable how sparsely insulated they are compared to 1980s kit. It's very clear that insulation depth has undergone the same transition to "as little as we can get away with" as shown with the motor in the video.

Efficiency gains have come from better compressors, and to a lesser extent increasing use of built in drawers and compartments, to stop all the cold pouring out the moment you open the door. Were they still insulated well, particularly as we have better materials to choose from, running costs could be reduced far more...

Well, ok, you can provide accessibility alternatives to a Canvas. But does it make much sense to do that for something that would otherwise be text? Ok, granted that Leon Sans will probably be used for nice headers and such it would probably be feasible.
There’s nothing soulless about high density, it’s efficient, environmentally friendly and to your point allows and supports diversity in recreation and dining. It’s the inescapable future of human civilization, in a good way. Would you describe living in New York as soulless? It’s time to get over the dog/white picket fence/2.5 kids delusion.
There would definitely be a market for 'open source appliances' I believe. Appliances built to last, based on modular design, and with full documentation available along with plenty of hooks included to permit third party creation of modifications and enhancements. Basically, applications as a sort of durable platform. Want to be able to connect your oven via wifi and see an image of what's cooking or get a food of its current temperature? That sort of thing could be added a little addon card or module, etc. Of course, most businesspeople would look at that and say 'sure, even if you come to dominate the market, what THEN?' and not like the lack of a built-in way to force people to buy new product. But eventually you would expect there to be one person who would be satisfied with making a few hundred million dollars over a decade even if that shrinks later on.
He was fully exonerated though!
I completely agree and do not understand why anybody would choose to post under the actual identity in this day and age. Unless you're completely posturing (which, granted, I find many who post under their own names do) then you're going to piss of somebody, and by somebody I mean quite a lot of people. And in the era of social media lynch mobs, swatting, and all of this other stuff - why would you ever do that to yourself?

I think it's also nice to have your words weighed against themselves rather than against your reputation. When well regarded people are inclined to agree with you because of that, rather than the quality of your words. When a pariah, vice versa. It's also interesting to give misleading hints to ones identity and see how, if at all, that affects response. For instance this account is named rjf72. I expect nearly everybody that noticed that would then assume my first initials are RJF and my birthday is 1972. It's actually just a neutral reference to Robert James Fischer 1972 - the year Bobby Fischer defeated Boris Spassky to become world champ. Granted I suppose that outs me as enjoying the great game, though. That part is true.
There are problems with that. For one, consider that if all of a country's debt were denominated in bitcoin. For instance, the government issues bonds that can be redeemed when they mature for some quantity of BTC.

Now consider what happens if the value of bitcoin goes up suddenly. The government now is much deeper in debt than they were planning to be.

Sometimes having your own currency has benefits, for the country and for the world economy as a whole. For instance, if a country goes into recession and the value of their currency drops, then their debt can shrink (if it's denominated in local currency) along with the economy so that it doesn't bankrupt the country. Also, when the price of local goods drops with respect to other currencies, it encourages exports which usually helps the economy recover.

If you use a currency controlled by some other country or institution (i.e. the Euro), you don't have these safeguards. That's true as well if the currency is controlled by no one in particular (e.g. Bitcoin).

I don't know what Zimbabwe's particular problem was with their own currency. Sometimes using an external currency makes sense (like the Bretton Woods system in Europe before the Nixon shock in 1971). But it can be dangerous as well.

(A real economist could probably explain this all better. I just recently happened to read a book on all the problems with monetary policy in Europe written by Yanis Varoufakis, who served as Greece's finance minister for three months.)
I'll recycle a comment I made in another thread a year ago:
When clearing out my grandmother's house a few years ago, my uncle and I almost broke our backs trying to get the freezer out. It felt like it weighed a ton, even empty.
My grandmother told us it had been a wedding present, and that they had been totally awestruck at the time at the generous present from her parents-in-law. After all, a decent freezer cost at least 2,000 kroner! (At this time, the average yearly gross pay was just in excess of 7,000 kroner.)
My grandparents married in 1950. Since then, monetary value has been reduced twenty-fold.
You can still buy a top-loading freezer for 2,000 kroner; I just checked.
So - in 1950, you had to work for five months to earn money for a freezer (after taxes.)
In 2017, I have to work one day for a freezer (after taxes.)

Yeah, large supermarkets tend to have salad bars, suburban or urban. Wal-Mart has grocery items, but you're not going to find a salad bar at one. Same goes for Target. You're also not going to find a salad bar at a Trader Joe's or an Aldi's.

But your typical large-format grocery store will have one. It's hard to talk chains and be comprehensive because American supermarket chains are not national. But whatever your market's equivalent of Wegmans/Publix/Kroger/HEB/Meijer/Albertsons/Hy-Vee should have one.

I got interested in typographic animation a while back, there are two related Wikipedia pages: "Motion Graphics" [1] and "Kinetic Typography" [2].

There is not a lot of info describing algorithms to perform Kinetic Typography that I could find. There are a few tools for doing Kinetic Typography for After Effects [3] and a couple other random software products of varying quality.

Btw, After Effects seems to be the closed-source reference implementation for all sorts of complex and cool looking effects. If for some reason all releases and source code of After Effects where to disappear from existence, it would set back the whole field of Motion Graphics by 25 years...

The Amiga had emulators to run DOS and Mac software. Sort of the OS/2 effect where they ran DOS and 16 bit Windows apps so there was no need for native OS/2 apps.

Commodore had a nickle and dime marketing plan and made PC clones as well. The Commodore 65 was going to be the next 8 bit C64 type computer after the C128. But it never got out of prototype.

Mac and DOS/PC tech caught up to the Amiga around 1987-1992 and Amiga could not make a newer chipset in time to compete with them.

The Amiga was like the Mac but with true preemptive multitasking and 1/3rd the cost of a similar powered Mac. Amiga didn't earn a lot of money with the Amiga because they lowballed the price and Apple won because they highballed the price until Steve Jobs could come back to fix the company. Amiga had no Steve Jobs savior and went out of business because the DOS/PC cut into their sales too.

> Can you tell me why is the range so wide? And are you saying the top end is of equivalent quality, but cheaper in Japan?

I'm not a specialist, but the cheaper frames here tend to be plastic.

The more expensive frames are almost invariably metal, and then the special flexible plastic and titanium frames go for around 10,000+ JPY.

Normal lenses are cheap ("free" with frames), but if you go for fancy ones (bifocals, transitions, blue light filters, ultralights, etc.), the price goes up.

I've almost invariably bought the 4000-5000 JPY frames and they always look nice and function well.

In the US, however, Luxottica tends to control the frame production/pricing, so frame prices are really out of control. That's why other options like generic frames straight from China are much cheaper.
