So we should allow Chia to waste tons disk drives instead as a consensus mechanism?
That's incorrect. There were plans to switch to hybrid PoS in 2018 which were (surprisingly even to Parity node devs) rapidly shelved. Since then a new design is being slowly worked upon. There were no plans to switch in 2019 that I recall.
Of course, that's why it's muddy on how you should compare the energy costs. Bitcoins energy costs are 99.9% related to protecting the asset, they are not related to the functionality of the system.

Likewise financial systems have little to do with protecting fiat, banks are backed by governments businesses like paypal hold money in banks, etc.

So to compare bitcoins energy consumption to an entity that spend energy in an unrelated way isn't entirely fair - there is some merit there, but not much.

In my experience, this cuts two ways. Some companies hire what about to PR flacks to respond to complaints with bland, vague apologies and company hype. The good companies have real support people tasked specifically with engaging on social media to help users fix issues, especially common ones. As you might expect, I tend to prefer to do business with the latter, and I suspect I'm not alone.

I don't think it's true that Proof is Stake is less resilient personally, of the 30-100 proof of stake chains that have been running for over a year now, I don't believe there have been any consensus attacks, and many of those would be far easier to attack (as the cost of doing so is relative to the market cap of the native coin)

On the other hand, we did see consolidation of >50% of the hashrate on Bitcoin, due to mining pools. That was only short-lived because the mining pool which accumulated that much hashrate agreed to cap it at 48% or something

It's often a power game: the more leverage you have, the better terms you can set. Women can filter out men interested in casual sex by making it everything but casual: making them wait, increasing the effort required, increasing the dating costs. You mentioned going on 120+ dates so I assume you have a large pool of men from which you can select.

She can use photofeeler as well to get a rating (as a 40 year old successful, average looking guy I usually get about 7 even though I'm trying to take care of myself, and I definitely wouldn't describe myself as handsome when I ask for dating advice).

Why is it surprising?

Paypal and any other company is interested in efficiency. Servers, air conditioning and power all cost quite serious amounts of money. UPSes and backup generators have to be sized for the load. Bringing large amounts of power into a building is also non-trivial. All of this means that most companies want to be reasonably efficient.

If Paypal found that their needs are covered by half the servers, leading to shutting down half their datacenters, they'd be quite happy about it. Plus less wages to pay!

Proof of Work on the other hand intrinsically wastes power. If somebody made a 2X more efficient ASIC/GPU, that'd mean that mining is now cheaper, which means you can do twice of it, which means that quickly everyone scales up and power usage remains the same.
Don't forget that in order to be secure, you have to turn off the features that make it so fast.

I have an old Mac with Xeon CPU that has not had software updates since before Spectre and Meltdown, et al. I bought it for its performance and have my workflow finely enmeshed, so I don't plan on applying patches that intentionally slow it down.

It sure is good at running Logic Audio. Don't need networking for that, so it is disabled. The CPU performance is more important than connectivity for its use and purposes. So it stays air gapped for the security, and unpatched for the performance.
Doubtful!
What's the startup that you liked the most that had to shut down?
We all know that sometimes having a good idea/service/product is not enough to make a successful business.

Sometimes businesses have to shut down due to not having enough users to cover their costs and sometimes (probably the saddest) when they get acquired by a company that just wants the talent and they shut down products.

I'm curious to hear about the ideas/products/services that people like the most but had to shut down and if there are any stories on why they shut down...

If there are enough people that loved such ideas/products/services, it might be worth it for someone else to reconsider, and having this strong and active community seemed like the right place to ask.
One of the ideas/products I liked the most was the multiple-cards in one (meaning that you can store multiple credit card accounts or even debit cards, into one plastic, this way you only carry one).

There was a company called Coin doing this in the US but they shut down. https://www.macrumors.com/2017/02/01/coin-shutdown-services-...

A company called Curve is doing this in Europe and seems to be doing quite well. (~$200M valuation). Unfortunately, it is not available in the US.

While many people might say that you don't need plastic if you have your phone and use Apple pay, maybe I am old school, but I still would love to have just one plastic (or metal since nowadays that's the cool thing) carrying all my cards.
> My time for having children is running out.

> Please encouragement only, no discouragement. I’m discouraged enough already.

IMHO, that's exactly the problem. Bear with me for a sec.

Unless you find someone who has the exact same objective and wants to have kids asap (i.e., a more transactional relationship), this will always be a major turn off. Your partner will feel pressured to make a decision quickly, and sooner or later will think the main thing you want is their sperm to have a baby. That's a recipe for folks to back off. Even if you believe you're not putting pressure, I bet they can smell it a mile away. It has a direct impact on your mindset, your behavior, and self-confidence, even if you believe you're effective in masking it.

It may sound counter intuitive, but once you stop trying "to find someone to marry and have kids", you may actually find someone.

The first step is to start accepting yourself and your life as it is -- and being proud of being single and having no kids. It is what it is. Cut the bullshit of dating coaches, hundred dates, dozen of books, and all the mental energy you're wasting obsessing about it. Give up the serial dating, and immerse yourself in work, or a cause you care about, sports, gym, hobbies, church, or whatever suits your fancy. Sure, make new friends and go on dates, but not because you want to "find love and build a family", but because you want to have fun and enjoy having sex every now and then.

Once you do it - truly do it - you'll be seen as more attractive, more powerful, successful, confident, remarkable, independent. You won't need anyone on your side to be the best version of yourself. And there's nothing more f*ing attractive than that.

Pragmatically speaking, you've already frozen your eggs, so you have a plan B for later. For now, internalize that you are enough. Once you accept it, everything else will follow.
You have to choose. Or don't choose. Don't overcomplicate a simple question.

The other inaccuracies in this article have already been covered. I noticed there was also a weird rant about mimalloc in there ("For some insane reason, mimalloc is not shipped in Visual Studio").

My understanding is mimalloc is basically a one-person project[1] from an MSR researcher in support of his research programming languages. It sounds like it's pretty nice, but I also wouldn't expect it to be somehow pushed as the default choice for Windows allocators.

One of my ex-girlfriends had a list of twenty things she required in a mate. I met 19 of them. She left. I met an amazing woman a couple of years later (at 43). We’re married and have an amazing 13 yo daughter. My ex is still single.

Maybe examine your standards. And I do mean this in a constructive way, by way of perhaps helping to troubleshoot. The way you describe your experience above, you present as high-expectation which though not needy can be high-maintenance in a different way. Maybe that’s true and maybe not, I don’t know you. My point is, the presentation is important.

Before the first date with my wife, we chatted for 3-1/2 hrs on okcupid. That we could hold a conversation that long made me optimistic about dating her. She chose the location for our first date. It was a noisy hangout bar and I could barely hear her. I asked for the check before she finished her food, my hope crushed. Why would someone choose a place like that to get to know someone? I’m walking to the car, dreading the ride back to her place when she asks if I’d like some ice cream. We went to Cold Stone and talked for about 5 hours.

Later in our relationship, we needed our communication skills to work through various conflicts. Even though we have high consensus about parenting, we don’t always see eye to eye. My point there, if you expect to find the perfect mate, also expect to be disappointed. What makes a relationship is the willingness to work through challenges.

Okay. I can appreciate the need for caution and careful direction when making significant changes to a financial scheme.

What I recall is a number of public announcements over the years claiming that the PoS transition was imminent, only to have it delayed at the last moment.

Yeah I've always thought the complaints about boilerplate were misguided. Whatever the cost in boilerplate implementation was more than made up for by having predictable, deterministic UI output. That being said, I think hooks did open up the state management design space quite a bit and classic redux style state management doesn't quite line up with it. Still totally valid as an architecture, though, in my opinion.

Some of the numbers in this article suggest a considerable bias coming from "an energy entrepreneur". His 'facts' disagree with those of reputable energy scientists.

Whilst cruely phrased, OP has admitted they didn't have a father figure in another comment. Why did you guess this?
99% of our AWS resources are terraformed, but developers constantly push back / want to use the console to create stuff to test or play around with. So we setup a separate "hack" AWS account and give them admin access in there, and have an automated job using AWS Nuke to delete everything in there once a quarter.
> with just a bit of a learning curve

This downplays how bad many developers are. I have some web dev friends that know how to use exactly one framework, one language, one source control, and never touch the cli out of a few commands stackoverflow told them to run. Changing from GitHub to bitbucket would be a major undertaking for them and that’s not even abandoning git.

They do well managing the small business apps they do, but they have no interest or motivation to learn anything different.

Now, keeping that bar in mind, there are devs worse than them that they complain about to me. They struggle with basic input validation (understanding what is executed on the client vs server, where strings can be trusted, etc).

Having come from Google, the tooling learning curve is only trivial if you already have a completely different mindset about what it means to be a programmer than 90% of the labor market.

Curious where do you experience slowness with Pandas?

Usually slowness in Pandas will be if you start doing non vector things.

Whenever you catch yourself writing a loop in Pandas you know you've gone the wrong way.

I too use Python extensively (with Pandas among other things) and usually Pandas is perfectly fine. (havent gone over 64GB memory usage yet)

I consider Pandas to be Numpy with benefits (methods) - since Pandas dataframe is basically just a collection of Numpy arrays. Those are about as close to C type arrays you can get in Python.

The only practical problems have been with regressions among supporting libraries such as pyarrow not playing nice with numpy when working with parquet files.

It's not that libc is supposed to not be a library, but those functions are the POSIX-defined interfaces to the OS. Linux is unusual in that it defines its stable interfaces in terms of the syscall ABI, enabling different implementations of the libc that can work semi-reliably across kernel versions.

How is "[using] dramatically less carbon" more secure? What are the security implications?

> Since its inception, Ethereum has aimed to implement a proof-of-stake consensus mechanism, but doing this without sacrificing security and decentralization has taken years of focused research and development.

A rather notable criticism of PoS, and its variations, is that it /does/ sacrifice decentralization to achieve its aims. I know that much smarter people than me have been working on this, and I don't follow research into consensus algos super closely, but I haven't heard or read anything validating PoS as the silver bullet it's made out to be.
If you'd like to learn the math behind that result and have not studied abstract algebra, a good book is Pinter's "A Book of Abstract Algebra" [1]. That will take you from beginning group theory through rings and fields culminating in the insolvability of the quintic.

The chapters are usually short, maybe 8-12 pages, with about half that being lots of exercises to help cement your understanding of the material. This greatly helps with self-study. And it's a Dover edition so is inexpensive.

I guess they're just trying to say that LLVM's control-flow graph is implemented as individually heap-allocated objects for nodes, and pointers for edges. (I haven't looked at the LLVM code, but that sounds plausible).

Even if those allocations are fast on Linux/Mac, I wonder whether there are other downsides of that representation, for example in terms of performance issues from cache misses when walking the graph. Could you do better, e.g. with a bump allocator instead of malloc? But who knows, maybe graph algorithms are just inherently cache-unfriendly, no matter the representation.

I’m not sure that’s how energy markets work… do you have any further reading? I’ve heard generally miners buy the cheapest electricity possible—typically oversupply that would otherwise be curtailed.

I don’t understand why Bitcoin mining is incompatible with emissions reduction. It sounds like an additional source of demand may make economical plants that otherwise could not be built.
