>> Unfortunately, practically all cryptocurrencies subscribe to the notion that early miners must receive greater rewards, even when they often already enjoy lower difficulty.

This habit of disproportionately rewarding early adopters is a universal feature of our economy and doesn't only apply to cryptocurrencies.
The reason why it's like this is simply because it's extremely difficult to get any project or company off the ground; the risk of failure for an early adopter is ridiculously high so rewards also need to be ridiculously high to justify those risks.

This is because most economic activity today is focused on seeking rents and building moats; so this has made the environment extremely adverse for newcomers; it lowered their probability of success and forced early adopter payoffs to skyrocket.
We live in an age where the moats are so wide that that even offering customers a solution which is 10x better isn't going to cut it anymore in terms of being able to turn any profit.

One might think that cryptocurrency would be immune to this; after all, the entire point of the blockchain movement was to fix such kinds of socio-economic problems - But having worked in the space for several years, I can say with confidence that incumbents in the cryptocurrency space have become part of the same problem which they were originally claiming to solve.
Development in the space is slow, inefficient, lacks a clear vision and the incumbents of the cryptocurrency space lack any incentives to give newcomers a fighting chance. They will happily let the most promising new projects drown in the noise of popular mediocrity.

The hypocrisy of it all is unmistakable. I've seen the ugliest side of human nature in this industry. That said I'm still cautiously optimistic but it's clear that something has to change at a social level in order to move forward.
Aging/death and reproduction seem to be closely related. I suppose maxander would counter that some mutation, given the many people who have lived before, should preserve reproducibility and youthfulness if fractional plasma is able to, but I'd counter that maxander is measuring (or guessing really) the probabilities wrong.
Curious why you claim that. It can be used the same way as React is used, and React is largely touted as something that is fitting for large apps.
> But if you're building an embedded device that will be deployed in any sort of volume, a small application processor running Linux will make your life dramatically easier.

Can you name some? I think of most embedded network stacks as being easier than raw socket APIs on Linux or Windows.

Programming network on Linux only looks that easy because of megatons of ready to use abstraction libraries available.
Which plant? Which Roomba?

According to the materials released by Qualcomm in 2018 (by which point, the Roomba i7 would have already have had lines in that plant), the processor used is a ARQ8009, a quad-core ARM processor commonly used in smartphones[0]. It's tough to find prices because the contracts are negotiated individually, but I'd put money on those chips costing much more than $1.00/piece.

Comparing VSLAM to lidar in any way besides saying that they technically can both be used to measure movement is also incorrect, and to actually call it a "kind of a cut-rate lidar" can only be due to a fundamental misunderstanding of VSLAM, lidar, or both.

Lidar measures distance along a single axis, with no additional information provided. You get movement by measuring changes in position by directly updating the distance value and inferring position change. It can be made robust by adding multiple lidar sensors, but is subject to weird edge cases with reflective materials or sunlight.

VSLAM only can measure change in vehicle position through the estimated position changes of significant image features through time, and provides no information about vehicle distance to the surroundings while the robot is standing still. You'd require stereo vision for that, and that does require more processing power, typically including a GPU like the one included in the NVIDIA Jetsons. You'd also typically use sensor fusion with an IMU, odometry, etc. to help with that.

Without stereo vision, you need motion to estimate position, which fundamentally makes VSLAM different from lidar, and makes your claim that it is "kind of a cut-rate lidar" completely false.

I'm not sure which DSP acronym you're referring to as a budget version of image processing , but if it has to do with digital signal processing, then yeah, of course. That's kind of the definition.

Yes, this is a very good point. Low-end application processors capable of running Linux are also very cheap now and it is easy to build a minimal system for around a few bucks (eg. Allwinner F1C100s, although it does not have an Ethernet MAC built in). Not great for hard real-time stuff, but if the requirements there are limited a separate microcontroller could work.
This is brilliant. It's shocking how well this works.

I wonder at what point do they turn to the Sicilian town model: Towns with a shrinking demographic sell city-owned homes for $1 as an incentive for new residents.
The stock-to-flow model posits a causal reason for the price: a roughly constant influx of money buying a declining rate of BTC production. This seems a lot stronger than technical analysis based on "fear and greed" psychology.

>It's an unfortunate situation yes, but the alternatives aren't better.

You can look at Sweden and see that is not true. Only .03% of population has died. That is 3% of 1%. [0]

It's not as if deadly flu's and other nasty diseases that people have to avoid naturally are not going around all the time anyway.

>You're right, it's more like the Spanish flu, which killed 3% of the world's population at the time, or 180 million people today. That's not a sacrifice we should be willing to make.

It's not killing 3% of the population. More like 3% of 1%.

~60M people die every year worldwide. Coronavirus barely moves the needle.

>I don't see how deforestation in the amazon, which usually has to do with consumerism in places like the US, has anything to do with the population of Brazil.

I live in the Amazon. Humans are like a plague of locusts, cutting down all trees and killing everything that moves. Deforestation is mainly from the poor doing slash and burn. And from people just trying to earn a living (the wrong way), more and more of them every day. (FWIW I'm here showing a better way. ie reforestation)

>So you want some of the most vulnerable populations among us to sacrifice their safety and quality of life for the rest of us? But you're unwilling to do the same for them? That feels rather selfish to me.

No I said protect the vulnerable and let the rest self-isolate if they feel the risk is warranted. As in, don't bring the virus into old folks homes.

You talk as if you think the common cold disappears after people hide in their houses for awhile.

And as if the world can go on shut down indefinitely.

The body, when it is healthy, generally kills cancerous cells on its own. This is, from what I understand why many cancers come with sickness/age, because your body doesn't react as robustly to broken cells as it did in health and youth. Something like "age reduction" could end up being a cure for many cancers, one could think.

FYI: Philosopher Harry Frankfurt wrote the classic essay "On Bullshit", defining the concept. Unlike lying/fraud, where falsehood is instrumental, Frankfurt defined bullshit as potentially false speech where the truth simply wasn't important. Bullshit is characterized by giving the surface appearance of confidence, intelligence, or a convincing argument; whether it's actually true or not is besides the point.

The essay is only 20 pages and available here:

Ok, you try sending $50K or $500K to Argentina or Russia or China and let me know how quick your transaction goes through.
If you flip a coin at the decision stage, then you would have a 50/50 chance of winning. But that approach would mean you’re disregarding information that you can use to increase your chances of success above 50/50. When you make your initial choice you have a 1/1000 chance of guessing correctly, meaning there is a 999/1000 chance that the prize is behind another door. By eliminating 998 doors from contention, you’re not changing those odds. There is still a 999/1000 chance for the prize to be behind a door other than the one you initially picked. Only now, instead of having 999 doors to choose from, you only have one. So by switching your choice, you increase your chance of success from being whatever it was initially, to being (1 - whatever it was initially). Which will always be greater than 0.5.

This is materially the same as being given a choice between opening one door randomly, or being able to open every other door. Because the conditions of opening doors prior to the final choice is that the door you initially picked can’t be opened at this phase, and neither can the winning door.
How's this?

Their solution is to provide very very wide monitors that the computer can be setup to see as 2 monitors so the 1 monitor is effectively split into 2. Not ideal (especially for someone like me who has 2 monitors, but keeps both of them vertical instead of horizontal), but better than nothing. However, they haven't actually moved any IT people into this kind of seating arrangement. I think it won't really work for a bunch of developers who are in their seats for the majority of the day.

Ask HN: Are React-like UI frameworks a fad or a genuine step forward?
I'm currently building a toy web application in Rust (end-to-end, using WASM on the frontend). When checking out the Rust frontend dev landscape, I found that basically all relevant libraries/frameworks are React-like:

- components that receive props and pass props to their children

- state updates triggered by async messages like in Redux

- some JSX-like syntax

Since I'm already familiar with React/Redux, this works out well for me. But I couldn't help but notice the monoculture. I suppose some of this is due to the unidirectional data flow model being a good match to Rust's ownership system.

My question is if this monoculture, as well as the general buzz around React (and similar frameworks like Vue or Svelte) is just a fad, or if we're all really taking a genuine step forward in understanding how best to structure GUI code.

From my POV, React is a genuine step forward compared to the jQuery-based apps from 10 years ago that were a hot mess of disjointed updates. But I'd like to hear some perspectives from others, esp. those of you who have worked with GUI frameworks on other platforms over the years. I have a few years of Qt under my belt, but I'm undecided on whether the differences between Qt and React/etc. are significant or just an artifact of the different programming paradigms encouraged by their respective languages.

I do hope he does consider Arizona as well as Nevada and Texas for new HQ options.

I think the tantrum is a bit unbalanced... same for Alameda county for that matter. For the most part there's been way to much opportunism from politicians over this issue. It wasn't meant to, nor could it stop the spread of COVID, it was always meant to slow progression over time so that it doesn't overwhelm emergency resources, of which, the US always had more than comparable western nations.

Beyond this, the risk for food shortages internationally may kill more than COVID ever would have if we don't start opening things back up again... printing checks against the future won't do much if there's no food being distributed in channels that are now closed. Unless you like a lot of fiber.

As a programmable programming language, I think it would be a shame if someone wants to use mutation and it's not available. On the other hand, if you don't want to use it, then don't use it! If you are a language creator that doesn't want your client to use variable mutation, you can even choose to not provide the construct very easily (see the Beginning Student Language which does exactly this).
And yes, this occasionally means that adding a

Here's my opposite anecdote: I live in NYC and in mid-March I had all of the headline COVID-19 symptoms, including most notably shortness of breath (which I've never before experienced in my life short of high altitude hiking). I got the Abbott test two weeks ago, and the result came back negative. I was so sure I'd had it, but now it's looking like maybe I didn't.

How Finance Gutted Manufacturing
I wouldn't hesitate to do so. It all depends on what kind of price / volume you're trying to target. For very short run, garage-shop types of operations, not only is handling surface-mount a headache, but there's a learning curve to getting any kind of circuit boards manufactured.

In addition to these microcontroller boards, you can find "breakout" boards for a variety of sophisticated components, and combine them on a carrier board that can be basic 2-layer hand soldered. It's quite a practical way for getting something simple out the door.

There's a lot of garage shop types of businesses that combine small scale manufacturing with customer support, and are not looking to get into high volume consumer market. For instance a friend of mine develops industrial solutions, where the customer might buy 10 to 1000 modules for their own use, or to support a product, such as some kind of weird agricultural machinery. These folks make their money by being local, easy to deal with, and willing to listen and understand the customer's need.

This is a clear case of "do things that don't scale."
Having a friend working at Arturia, I don't think they're "small shop" nor do they make "a lot of money" to be honest

I've bought a handful of ordinary things (bookshelves, a t-shirt, tire chains, coffee and pastries) with bitcoin, just for the heck of it. These are real-world things I would have spent other kinds of money on if I couldn't pay with bitcoin. I used bitcoin for its novelty.

Bitcoin itself is obviously unsuitable to replace cash (or banks, etc) in general, but I've been fascinated by cryptocurrencies since the David Chaum days, so I like to play with it. Speculating on it is more effort than it's worth, to me.

My USD$25 in bitcoin holdings did require me to check a box on my tax forms this year, though...
They can of course collaborate, it's not like there are federal regulations preventing that from happening.
This is splitting hairs.

Sure, everything can be used as a currency. Gold, bitcoins, fiat cash, snackpack puddings at lunch, seashells, etc.

Then there are qualities that make something a good currency, by modern standards. As others have pointed out with links to examples, being deflationary, irreversible, volatile, and having low coverage with unpredictable fees are traits that make Bitcoin not a very good currency. Yes you can hand wave about future promises to be a great currency or chore tokens, but that does not reflect the utility of Bitcoin right now as a good currency.

A true feminist would genetically engineer the human species? Why not erase sexes while we're at it?
I am fortunate in that my preferred name and my legal name are identical, and not the least bit exotic, so all the IT systems I've had to deal with over the years haven't felt the need to mangle my name.

I also have several pseudonyms I use for various purposes. I am an exceptionally private person, so I use a pseudonym for the poetry I write, and another one for the more serious stuff I write. I also have another one I created for some of the technical stuff I've written over the years, mostly because several of the companies I've worked for had this silly idea that any thought that popped into my head belonged to them.
People certainly used to use it before transaction fees became too high. It saw a lot of real use in dark net markets which AFAIK now use more privacy-preserving coins, since the bitcoin blockchain is simply pseudonymous. For regular payments Bitcoin has some tradeoffs, theoretically the high hash power makes it "safer" (though it's quite consolidated), it's somewhat less volatile than other coins due to trading volume, but its fees are quite high. It's basically dead for on-chain transactions under a certain amount.

Personally I think Bitcoin has great historic value and may become a collector's item similar to how a denarius still has value now, but its properties make it pretty bad for everything you would want a currency to be, except that it's deflationary and well-known. For anything you would want to do with it other than speculate, there is probably a better cryptocurrency (based on the actual tech/design of the currency) or non-crypto tool - it's like the Model T of crypto.

If you don't support the platform somebody else will complain OR send you some code to do so, at which point you're going to be seen as bad if you don't include it anyway.

It is cynic, but for platforms such as Android or iOS it is fully deserved IMHO. You'd _want_ to support these because, in all likelihood, you _have_ to work with them.
