The only major blockchains using proof of work and having considerable environmental impact at this point are Bitcoin and Ethereum.

Bitcoin has stalled in development so I don’t think it will ever change, Ethereum has been talking about moving to extremely low energy Proof of Stake for years (hopefully will happen soon).

Almost all the other major blockchains available - Polkadot, algorand, Tezos, NEAR, Solana, Cardano - are proof of stake, or similar extremely low energy consumption blockchains.

The environmental criticism of blockchain is therefore going the way of the dodo. There are many valid criticisms of blockchain but the energy consumption criticism is about to be technologically outdated. It will age like milk.

The only significant project using it is really Ethereum, and like I said, they have long promised to move on but have apparently gotten into a lot of technical trouble doing it, but they are still dead set on doing it.
I strongly suggest “How to Read a Book” by Adler. It’s an excellent discussion of types and levels of reading.

When faced with a large, imposing text, my method is:

1. Read the title page, table of contents, index, and introduction several times. This should make it clear what the book is about and how it’s structure.

2. Read it straight through from start to end. No notes. Don’t worry about not understanding. Intellectually, I’m very passive. Just familiarizing myself with the terrain. Keep in mind the knowledge gained from the previous step.

3. Read through again, paying attention to key concepts and terms. Make a list of key concepts and terms. Try to understand and resolve the concepts and terms in relation to each other and the structure of the text. This is still very passive reading. You shouldn’t be forming any opinions at this point.

4. Create your own outline of the text. If the table of contents is well thought out, this might be redundant. Still very passive. No opinions yet.

5. Go through again, summarizing all the key ideas. Still very passive, you’re just trying to map out the text. Not forming opinions.

6. Rewrite the outline, now including your summaries.

7 and above. Now, if necessary, start actively critiquing. That’s a whole different matter. And usually involves playing the author off other authors. You usually don’t get to this part. I’ll refer you back to “How to Read a Book.”

The key thing is to focus on passively understanding, rather than opinion formation.
>If they just designed their software how they want to and otherwise let it be

In my experience, that is what they're doing. Their software just happens to be adopted by more users because in a lot of cases it is better and does represent the future. You have that advantage when you support a lot of commercial users over a long period of time. Red Hat also has a policy of contributing a lot to upstream so that also adds to why they have success with other projects.

>If various Red Hat projects didn't find a way to create dependencies on systemd to encourage it's adoption

I think this is an exaggeration. I haven't seen any projects that have anything more than a trivial dependency on systemd to enable some optional functionality.

But the EU wants to move in the direction of a single sovereign nation, doesn't it? Letting citizens vote for EU level elections is a step towards that.

But most EU countries won't yet allow EU citizens from other countries to vote for, e.g. president of that country, to my knowledge.
Why's there a need to trust internet archive in this situation? If the content hash is no the ETH blockchain, then it's immutable. You can make as many copies of the underlying image as you want so that sticks around permanently.
This model gives you numbers. It takes you from the very vague: "differences in between-group preferences can cause segregation" to something concrete. "X difference in between group preference for Y will lead to Z-level segregation." And X is surprisingly small for a given Z.

I find Qt/QML for cross-platform mobile applications to be a great solution. It uses the same basic architecture as Flutter – they both do not use native widgets and instead draw the entire UI on a blank graphics canvas. I think that approach preserves the most code between platforms and reduces the kinds of presentation hitches that HTML web view and hybrid native widget approaches can run into.

In relation to the particular problems of technical debt related to third party modules mentioned in this article, QML rides on top of Qt which is a 26 year old C++ cross-platform toolkit with a lot of mature technology in it. I.e. there is a lot more "batteries included".

There are still plenty of times you have to "go native" to integrate something Qt doesn't cover but it apparently isn't as often as with Flutter.

I'm not a contact lawyer, but that sounds like it would be an invalid contract for lack of consideration. In the terms for future work being done, Upwork is requiring the freelancer to do more than a month of work without Upwork providing any consideration in return. No payment for work done, no promise not to extract the same unpaid labor again.
I don't disagree (nor totally agree) with your opinion about the matter.
But they don't take a 20% of all their freelancers earnings, they take 20% on the first $500 of your per-client earnings, then %10 of the next $9500, then %5 of any more work with your client.
Also, you are free to work with any client outside the platform 2 years after you start work with them.

It might be an outdated model of segregation? Maybe it explains the origins of segregated suburbs in the 1940s, but doesn't explain its persistence into the 2020s.
Contracting is a great middle path between 9-5 salaried employment and full-on freelancing.

You can get paid a lot more than regular employment, but you have to take into account that you don't get any benefits. How much that affects your quality of life depends on your location. For example, I live in the UK and have worked as a contractor on and off over the last 12 years. We have free healthcare so it's been easy. I don't care about other employee perks and in fact, even after paying out of pocket, it's still a lot more lucrative considering the work-life balance.

Freelancing sounds very attractive but what most developers don't realise is that you have to do sales from day one. And we all know how good we are at sales. It's too big a leap for most.

Contracting, on the other hand, is a lot easier to get started with because you can find contract work through the same channels as you'd find regular jobs.

In addition to the mainstream job sites (LinkedIn, Indeed, etc.), there are a ton of smaller niche sites where you can find contract work.

Once you get some experience working as a contractor, it's a smaller leap into proper freelancing. Plus, you can build your online profile, network and most importantly, confidence along the way.

I know in the big tech companies in the US, there's a bit of a stigma around contractors. So I'd avoid those and instead focus on the many other remote work opportunities available now.

I covered a lot of the why, what and how of starting as a contractor in these free videos -

It is. Worth noting that I know no one among locals that are permanent employees to earn < 2500 EUR after tax. Pre-tax as a permanent that's 45-50k EUR a year (with some margin of error). That's for senior level devs with > 10 years of experience. Junior or mid is way less. BI/Data science or web dev. Game dev and other types of development are low paid, as in western europe. I had my first shock when Microsoft offered a salary of 70k + bens for someone from cluj napoca to relocate to London around 2014, and they flat out turned it out because cost of living adjusted they earned more in Cluj. Go figure that out. Tbh if you earn 2.5k in Romania after tax you are way way better off than someone earning 4k in London.
There is a compelling argument that with the state of remote work, familial mobility and whatnot, it is not feasible for the states to tackle certain issues without unconstitutionally blocking non-state residents from using those services.
Absolutely beautiful album, and Myself When I Am Real is one of the best tracks.

It's crazy how Airbnb, amazon and this company don't care if the card holder and the user account holder are the same.

I work in finance and this is often a total no go in many industries , even with consent of the card holder.

But going strict on this will cause friction I suppose, just like CVV codes aren't mandatory on transactions, so some companies leave them out of the payment process. It only helps a bit during a charge back defense to have CVV and 2fa enabled.

I have read about other dodgy things that Upwork has done before, nasty bunch.

Predictably, this outcry will make them "rethink" their position on this one case and they will "apologize" and most likely not update the KYC checks and carry on as usual.

Maybe we are living in the world of "Brave New World" where there will soon be "Soma" pills of different colors depending on how we feel and how we want to feel.

The big question is ethics. How far do we go to understand, engineer, and change the very nature of what makes us human? Changing the very negative emotions for the future generation would change the world of great art like the next Poe, Van Gogh, Plath, and more.

This changes the very nature of what makes us unique. If everyone is happy, nobody is happy, right?
But there's no way to estimate the particular X in this model in the real world, and the notion that that X is the actual driver is just a bare possibility among others, not really argued for or evidenced.

If you made a model where groups have different preferences for "amenities" (nearby relatives, parks, yoga studios) that would at least represent a more plausible hypothesis. Although the parameters would still be impossible to estimate.

I get what you're saying though. Broadly speaking it might be theoretically interesting to set up various quantitative models for the XYZ chain.
> why would anyone read my blog?

Because you’d write high quality articles that help people solve problems, share them around as you write them, slowly grow some viewership that way, and eventually start to get organic visitors from search engines. It’s not very fast though, and it helps to know what you hope to get out of it, so you can target your writing.

I know people who get freelance leads from their writing, but I don’t get many myself. Just a few over the years I’ve been writing. I suspect this is because most of my articles are aimed at beginners, though. I would guess that higher-level stuff would attract more leads. One other benefit is that you have something to point to - I can say “Yeah I know React pretty well, I’ve been writing about it for about 5 years <here> and I wrote a book on it.”

Gotta stress that it’s not fast, though.

> Banks are bad at security.

I disagree. I live in Europe and all my online card transactions over a nominal sum (~$10) are tied to a certificate-based security application that requires confirmation on my phone. This same application is used by all banks and most government entities.

There are of course banks in the world that are bad at security, but “banks”, as a general term, most definitely are not.

The fundamental problem is, of course, that security is annoying, so any fundamental security improvement to online banking needs to be mandatory and centralized, and if there is no will to push something like that I’m not surprised nothing happens.
Cool, thanks for expanding and congrats on the project!

I've built both native and cross platform apps.

People and especially managers think that cross platform apps will save them money/time. However, they don't realisize that cross platform solves one problem and creates ten.

The developer experience is worse, the user experience is worse and you end up with a pile of mess after 1-2 years.
My first thought is, "Why didn't they eschew solar power entirely and 'simply' park it in the shade?"

Surely they considered that, and the wins would have been massive -- no sunshields needed. So I'm sure the downsides must have been massive as well. Not enough plutonium fuel, or perhaps it just wouldn't provide enough power over the life of the mission. And of course the radioactive fuel would generate its own heat as well.

Now I need to find out more about that decision....

edit: Another commenter mentioned, "The earth's shadow never reaches L2 anyhow - it's only penumbra at that distance since the angular size of the earth is smaller then the angular size of the Sun." If that's correct, then there was never truly an option of "parking it in the shade" anyway.
>If we were rational and serious about making the biggest impact, we would reduce car dependency

I've spoken to a subset of EV proponents who would strongly disagree with this. They say that it's not feasible or even possible, or maybe even acceptable, to convince enough people to change their lifestyle this radically. Therefore, we need to just all buy EVs.

Personally I agree with you, although the huge boost that continuing new development gives to my field as an engineer is undeniable.
There are GUI clients for IRC that don’t need any “command line options” (some don’t even support them).

Ask HN: Why USA, the most tech-forward country in the world can't control Covid?
Seriously curious about this. USA is the most tech-forward country in the world among a few others.

It has the highest number of doses being already administered to its population and yet the cases of covid are on the rise. Deaths have again started to pickup.
If we've "been cultivated", they're delicious because our (non) ancestors who didn't like the taste got weeded out by evolution.
I agree, the much better solution would be to reduce the cultural reliance on cars in general. Incentives for more work from home, more walkable and bikeable cities, more amenities locally, better public transport... Unfortunately at least in the US such changes are basically impossible due to the culture, at least currently. A generational die off or two might radically change that.

New York is one of the few states that has them ahead. New York City seems to be lagging behind on coverage generally, but that may just be an artifact of it being a very big city, big enough to be called out individually in a list of mostly states.

I think so, this story is strange. Working for a client you meet on Upwork or negotiating payment outside of Upwork goes against their ToS so you would expect them to deal with it at least morally if not legally.

If Robin were to pay the client outside Upwork for the $12500 charged back does the freelancer still owns Upwork 20% of the earnings? If Robin isn't paying and Upwork isn't covering the fraud is the freelancer still required to pay the 20% fees?
You seem quite determined to leave inadequate margin for error. :(

The most important rule of audio recording is "always be ready to roll tape". What the engineer does is of little consequence compared to the talent. Don't ever fuck up a keeper take.

Recording with some extra bits means that even if your gain staging was bad, you just get some extra uncorrelated noise, not correlated quantization distortion.

As for whether this stuff is perceptible, there are two issues at play. First, differences which are not perceptible during production can result in a perceptible difference in the final product. This is easiest to understand with a visual analogy: if you have inadequate resolution of an image during processing, the end result may be slightly defocused and smeared.

Second, as I described elsethread, quantization distortion is a particularly pernicious form of degradation, poisonous in small amounts. https://www.youtube.com/watch?v=8KkS4NSv-0M It is hard to listen for it during production, so we defend against it by giving ourselves lots and lots of headroom.
> One thing I can't shake about the EV "revolution" is that it's going to require a massive expansion of our renewable energy capacity, like solar and wind, but we also need that renewable energy for other things, like household energy usage.

The big problem we have with renewables right now is matching generation with demand. Solar is really cheap for daytime generation, but what are you going to do at night?

Electric cars don't have that problem. They're parked for most of the day, they need to be charged once a day or less, so they can be charged whenever renewable generation is available. Which makes deployment of renewables more economical, which means we get more of it.

> If we were rational and serious about making the biggest impact, we would reduce car dependency so the green electricity we generate can go to less wasteful means.

We can do two things at once.

The biggest thing we can do to reduce vehicle miles traveled is to relax zoning near urban areas to allow higher density housing to be built closer to jobs. That works, it makes housing more affordable (which is independently good) and people waste less time commuting.

It also takes years before the new housing is actually built and even then doesn't solve the entire problem. You can't replace last mile truck deliveries with higher density housing or mass transit; you need electric trucks. Nobody is going to build low ridership mass transit to the low density suburbs that already exist, and they're not all going to cease to exist.

100% of cars are not going away anytime in the next century, but making the large majority of new cars electric is feasible within the next few years.

This is not a problem with a single solution. It's a problem with 100 solutions that each have a niche and you solve the problem best by deploying them all, each in the place where it makes the most sense.
