Say you want to transfer a billion dollars 3000 miles. A billion dollars is 10 million Benjamins, which weighs 10 tons. You're not fitting that in a Tesla. More likely, you'll put it in an armored car and hire a few armed guards to go along with it. If you need to transport it overseas, you need a freighter (and a week) too. Now the energy cost of that Bitcoin transaction doesn't seem so bad.

The institutional interest in Bitcoin I've seen lately seems to assume a thesis of dollar depreciation and Bitcoin usurping its role as the global reserve currency. Ordinary people are not going to transact in Bitcoin under this thesis: they'll use dollars, pounds, deutchmarks, lira, yuan, etc. for their ordinary domestic transactions. Only banks, importers, and other major financial institutions need to convert the local currency into Bitcoin and settle up on the international markets, and these transactions will be in the tens-of-billions. Most of Bitcoin's drawbacks go away with this use-case - it doesn't matter that the network is limited to 4 TPS when only ~hundreds of transactions are conducted daily, and the energy use per transaction is similarly minimized. Bitcoin's advantages in trustlessness and lack of a central authority are hugely important in international relations, where nobody trusts anybody else and there's no higher authority to appeal to.

(Stellar's even better for this use-case, and has had a similar recent run-up, but currencies have strong network effects and it's unlikely that Stellar could get the name recognition or trust that Bitcoin has gotten.)

It's an open secret that inflation is purposefully miscalculated.

As another commenter notes, CPI leaves out many of the most major expenses, e.g. housing.

There are estimates as high as 8% annually when you account for everything.
Yes and No. They are not mutually exclusive.

I find that generally I'm much more productive in Emacs, so I use it most of the time. But I reach for the IDE when it makes sense.
You mean "affine types". Linear types are required to be used while Rust allows one to manually drop a type. This allows you to get the next state and do nothing with it while a linear type would compel you to move to the next state.
> What's wrong with multiple implementations?

It's absolutely great, and I'm saying that as someone working 5+ years on an alternative Python dialect (exactly with a motto of "down with toxic lead-acid batteries").

> Also moving it into the language doesn't mean people will work on that one implementation.

Only on that one - god forbid. But gather around that particular implementation to make it better and polish rough edges - for sure. (While the rest of impls will remain niche projects unfortunately.)

> I (and obviously many others here) believe that this is _bad_.

And me, and many others, believe it's good ;).
The problem with "interventionistas" with little/no understanding of bitcoin is, they look at one feature/component of btc's game theory in isolation and state "I can do this particular thing cheaper/faster/easier" while ignoring the 100 other aligned incentive structures that are lost with their 2nd/3rd-order-effect altering solutions.

Bitcoin is too elegantly designed to approach in this fashion.
Hasn’t this always been free? I’ve taken it twice in the past for free. When it was on iTunes University.
Miners are incentivised with transaction fees alone after all the bitcoins are mined.

Very cool project! I love stuff like this. I actually started a very similar fun project last week[0]. It's very much just a thought experiment, but the most interesting thing about it (I think) is the use of dynamic rather than lexical scope to control state. It's also designed to be extensible using python, js, and html.

I did take a quick look at the Wasp real-world app and was sort of disappointed. It seemed like a single file with lots of weird syntax that pulls in a regular old React app. Is there something I'm missing?

Mining continues but the reward comes solely from transaction fees.
The title is misleading, the lecture videos and materials for that course have always been publicly available.
Very easy to use
The problem with all these Linux/BSD attempts at mimicking the Mac is that due to the nature of the open source components, they are mostly able to mimic the "look" but never the feel.

The one thing that makes OSX different even from Windows is the way it "feels" when you are using it. And the simple things you can achieve in a very simple and intuitive matter.

I just stumbled upon an example some days ago, when I needed to add a screenshot image to a PDF. It was surprisingly easy in the Mac: Double click the PDF to open it in preview, double click the image to open it in preview and then drag the file icon of the image into the pages view of the PDF. And the image is inserted as a page in the PDF without any issues.

To do that on Windows or Linux (I use Mint in my PC) I think I'll have to print the Image as a PDF and then use some other software to "stitch" the two files together.

And like that there are a lot of other UX small things that make for a more pleasant experience in the Mac, particularly for end users.

> What happens when all the bitcoins are mined?

Then miners will get only the transaction fees. But it's still the same process. (Anyway, that won't happen, the number of available BTC to mining will asymptoptically approach 0, but will never get there.)

I also use fast.com to test and have noticed that while using nordvpn I get no service at all (errors out.) I wonder if this is nord or Netflix since I can watch Netflix under the VPN it’s just painfully slow.
Another thing, as evidenced by the confusion in this thread:

The homepage is kind of lacking. I’d suggest linking to some docs that explain the things you have in this thread so potential users can evaluate the product better.

Right now your homepage is:

- company name

- sign up button (which looks weird for me on mobile FYI)

- what is a PWA

- benefits of PWA

- companies using PWAs that don’t use our product for their PWAs

- sign up button

- team

- contact

Include a docs section or something near the top seems like a good idea IMO

That's not environmental pollution, but you're not wrong about the potential for conflict. War could erupt between Egypt and Ethiopia at the drop of a hat over the GERD. Usually cooler heads prevail, but water is going to displace oil as the primary driver of resource wars. Arguably it already has, but we're simply in a resource war lull for the moment.

> I think a lot of nuance is missed when discussing Bitcoin and its consensus mechanism as the only way of running a blockchain

Bitcoin holders are financially incentivized to steer everyone else toward Bitcoin.

As long as early adopters are financially invested in alternative currencies failing, we’re going to continue seeing a focus on Bitcoin.
The point here is that bitcoin is incredibly transparent, which on one level one may welcome, but on another certainly not.

(a) providing cash level privacy to customers, which (b) they should probably value more than they do.
Electricity gets generated and either consumed or wasted. Bitcoin eats excess available supply.

Ask HN: How to convince my bank to not require SMS based 2FA?
I got a notice from my back (First Republic Bank) that later this year they will require SMS based 2FA.

How can I convince them his is a bad idea? First off the NIST basically declared SMS 2FA insecure. How does a bank not know this? Sim Swaps, social engineering the phone company, etc..

Second, if you travel at all suddenly you can easily have internet access (hotel, cafe, airport) but not have SMS access.

Has anyone had success convincing their bank not to require SMS 2FA?

Requiring 2FA I don't mind. I'd prefer TOTP. I'd put up with email 2FA (Steam does this). But SMS absolutely not!

First Republic Bank is a Bay Area bank so I partly brought this up here hoping there might be enough actual customers here that agree and would be willing to contact the bank and voice your objections.
Sure but ya this isn’t health advice! I did under supervision (in a sense) by my doctor. He originally wanted me to go on proper meds but I asked for a few months to address it on my own and he was astounded by the results.

Big caveat. I also went from doing 1 or 2 bouts of exercise a week to about 4. Exercise makes a huge difference too.

Ok so here’s what worked for me. I took things twice a day (first thing and with dinner).

Omega 3
Olive leaf extract
Green coffee bean extract
Magnesium
Potassium
Garlic
Hibiscus tea (this was a tea not a pill)
Also vitamin D and C (for immune not BP).

The olive leaf / green coffee bean / hibiscus are all well attested (if memory serves) as vasodilators. I think garlic too. The Magnesium and potassium also have an effect.

The Omegas were more for inflammation.

I also tried Apple cider vinegar but had no bad effect when I dropped it. Also started doing turmeric and boron but not related to blood pressure.

I joke with my doctor that to avoid taking that 1 pill I’m now taking like 20 pills. But much prefer this.

While under this regime I also got into much better shape, mostly through diet (cutting out carbs), so for me the supplements were a short term / med term thing while baseline health improved.

Final note. Genetics play a huge role in blood pressure (and have some family history) and of course your stress levels too.

Edit: just remembered, reducing my caffeine intake was also a big part of the story. 2 cups a day is now my max vs 4+ cups.
Range concern won't evaporate in the US anytime soon simply because of how far spread cities and forests are and how much people like to roadtrip, specially in the Summer. When I used to hike pre-COVID, I used to do 150 miles one-way easy, and sometimes even return same day.
It's not the same. Twitter is designed to constantly pump content and social engagement at you. Once you start scrolling on Twitter, it takes some effort to put it down.

HN is designed to show you 30 "trending" stories at a time, and its refresh rate is pretty slow compared to social media like Facebook, Twitter or Reddit. From personal experience, it's pretty easy to load up HN, read a handful of stories/comment threads, and close it. With Twitter, I utilize iOS's built in app blocking features to lock me out of Twitter after 30 minutes. Without that restriction, I have a hard time getting off Twitter on my own.
The coal is there to remove oxygen from the silicon. That it also provides the heat required is just an added bonus.

You could add carbon capture equipment and use nuclear or hyrdo electricity to break down the CO2 back into carbon, and this carbon could be reused instead of fresh coal which would also limit the emission of other pollutants. This is a substantial additional cost though, and the conversion of an existing plant to run this way is non-trivial.
I'm more inclined to assume this will be exploited by police, imagine being convicted of a crime they claim you remembered while in pre trial detention.

Of course it could be as simple as swapping your video tape with one they created in order to incriminate you. As much as I really want this technology, it could do wonders for multitudes of disabled people, I'm more concerned about it being abused.
The difference is that Google can do whatever it wants because it is a private company.

Misapplying the law because a private company does something is not a logical argument.
Simply eradicate the silly income taxes and use traditional real estate tax, energy taxes, road tax, sales tax, and other waste taxes. The problem is that countries that messed up their tax system during a war aren't going to revert them so they are forever dealing with the market results of taxing income instead of taxing resource usage.

Why shouldn't you buy and hold important resources if the society isn't making those resources fund the system?

Having these free gifts for whoever had money seemed very clever back when the rich people from a system didn't have to let foreign rich people have the same access to their plunder.

thanks for the feedback, I agree having showcases is crucial for showing what can actually be built with Wasp.

We ourselves built a copy of Medium with Wasp - feel free to see it deployed here (https://wasp-rwa.netlify.app/) and check the code here (https://github.com/wasp-lang/wasp/tree/master/examples/realw...)

For the super simple example with less code check out TODO app built with Wasp: https://github.com/wasp-lang/wasp/tree/master/examples/tutor... (check out main.wasp and then the code in ext/ folder)

Hope this helps!

Right, that's fair to say.

But the economist in OP is essentially ignoring where bitcoin actually get's it's value from and only focusing on it's electrical consumption.

Bitcoin means different things to different people. But many see it as the single best hedge against modern monetary policy.
God damn, now I want to eat a burger.
I agree that there be dragons, but maybe simpler metrics would be better? As an example; what if I could easily filter by crates supported by a team rather than a individual included in all its dependencies. That could be a way of doing risk mitigation. The metric would also work as incentive to create a more connected community.
Thanks! This is a bit of a deal-breaker for me because I use Plotly a lot for EDA.

My ideal IDE would combine PyCharm's variable explorer and interactive debugger with Jupyter Lab's plotting, widgets, and the ease of rearranging cells. Oh, and I really need a duplicate line shortcut, which PyCharm, Spyder, and RStudio all have, but Jupyter doesn't for some reason.

It wasn't referring to the specific identifier "it" here, but more in general as I took your point to mainly be about "if there's a benefit to using other values for X in other contexts", meaning that putting things into variables only serves the functionality of reuse in different contexts, not also to name passages of code.
Disclaimer: this is all _very_ rough and approximate - my only qualifications are that I hung out with neuroscientists in grad school.

You can largely think of mammalian eyeballs as camera sensors, which see the world and pass lightly pre-processed pixel data through cables (your optic nerves) into the back part of your brain where your visual cortex "starts". That pixel-level data flows through a kind of pipeline of filters which detect increasingly complex features the further forward they are in the brain.

The first few layers are detecting fairly understandable things - like little lines bits, and corners that turn left, or turn right, etc. The downstream layers take those detections as inputs to detect more complex features, e.g. helping to detect larger closed shapes and determine which pixels are inside vs. outside those shapes. This data then feeds into higher level object detection, etc etc.

What's really cool is that the first few layers of this are more or less laid out like an image in RAM. A star pattern of shapes in the real world would cause a star pattern of neurons in your head to start firing. This sensible layout has really helped neuroscientists grasp what the brain is doing, and has IMO been one of the big reasons we've been able to take such inspiration from neuroscience into machine vision.

Apparently though, the turtle brain doesn't work like this at all. As far as I can tell, the turtle visual processing system is just a big weird soup of neurons with no familiar structure to it. It works somehow, and I'm excited to follow the progress of decoding what it's actually doing.

By the way, if any of this interests you I recommend grabbing a copy of David Marr's book "Vision". It's probably pretty out-dated at this point, but it's wonderfully written and I think gets the basic points across very well: https://mitpress.mit.edu/books/vision
Sounds like they have read-replicas, why can’t they fail over to a read replica as the new master?
FWIW, Khan Academy is pretty well aligned with Common Core, at least in terms of material covered: https://www.khanacademy.org/commoncore/map

I think a lot of what people complain about with Common Core is bizarrely written school materials that were developed by some bureaucracy and don't make a whit of sense to an adult who already knows the skill, let alone to a kid. Khan Academy definitely does better on that count in my opinion, so it's a good supplement.

The people making the transactions pay for that energy. At 10 cents a kWh that's $16.5 , right in line with the current transaction price. Some people are getting enough value from the transaction to purchase that volume of energy. Who are we to tell them how to use the energy they purchase?

Ask HN: How are you using video?
With the switch to WFH over the last year a lot of people are using video a lot more than they use to. Whether it's just being on more Zoom calls, creating webinars/screen-casts or preparing more video marketing content, it seems that video is becoming a much larger part of most businesses. Personally, I've invested in converting my Sony A600 into a webcam and bought a mic and keylight, giving me a much better video appearance on calls.

Have you personally started using video differently, or has your company or business?

While the disconnect is true, specially in what concerns FOSS views of the world and how real studios work, middleware like Unity and WaveEngine are indeed being picked up by major studios.

On the Switch alone, a very big chunk are all based on Unity, more than 50% as per Unity official statement.

Also although the engine is still mostly C++, they have been porting the rendering pipeline into HPC#.

Does the keto diet help you lose weight?
I think one practicality of it that you forget is the difficulty for people too, not just for businesses or government entities.

For example, people are used to banks always being open 9am to 5pm. With the approach you mentioned, it means that twice a year they will have to shift it. It means you will also have to shift your entire schedule, and calendar, and literally everything. Now think about some shops and places that will NOT be switching it and decide to keep the same hours. Then add-in the fact that some shops already change their hours even with the current system. For example, I have a daily recurring alarm for 7am. Under this proposed system, I will have to manually change it twice a year (while now it is done automatically due to the entire timezone switching twice a year).

You will simply get a logistical nightmare, since changing the entire clock is much much simpler than shifting each individual little scheduled item in your life.

Tl;dr: while i agree that logically your approach of shifting individual scheduling items to align with the daylight hours makes more logical sense, it makes more practical sense to just switch timezones twice a year for that purpose.
This was hilarious!
