It's convenient for some things that would otherwise require a reduce (but where reduce isn't particularly more efficient, because you just need lookahead/lookbehind) or an imperative loop, like transforming a list to a set of moving averages over the list.

It's a little more expressive than reduce our imperative lots
loops in those cases, too.

You're so angry about the greenhouse gases that you're completely missing the logic behind an energy currency. You complain that the energy and dollars are spent speculating because you're flat out ignoring that miners are re-investing their profits to become more efficient and productive. Bitcoin mining is a rat race to develop efficiency in technology and energy deliverance.

Oil companies capturing the wasted natural gas, Hydro dams capturing the wasted water energy, etc. Bitcoin is a battery or energy credit where areas with abundant energy can benefit from their standing in the world and benefit the people of the region. Bitcoin has its ebbs and flows but eventually balances to where your typical american household cannot afford to mine bitcoin and profit.
Oh, that's interesting.

Somewhat related to that, when I was checking out apartments in the various CBD buildings, only the Eureka Tower ones seemed to have been built with any kind of quality or attention to detail.

Eg Surface finish of paint jobs was well done (even in non-obvious areas), gaps where surfaces join were consistent, and that kind of thing.

You could really tell it was done by people who gave a shit. Or at least, when looking at other places (Freshwater Place stands out), those ones were all clearly done by people who didn't. :/

So, the reports of problems due to potentially incorrect construction techniques in those buildings don't really surprise me.
I have some green sensibilities, but I'm more of a Post-scarcity
Socialist. Backing a currency with a scarce resource serves no purpose
other than to keep us serfs "down on the manor" so to speak.
Standards of living didn't start rising significantly until fiat money
really took off. Societies and governments give currency value; it
has little to no inherent value on its own.

But the primary philosophy behind bitcoin is right-libertarian / Ayn Rand
/ a return to the 19th century with futuristic technology.

Go look up the Cyphernomicon for instance, where you'll find Tim
May cheerleading for cryptocurrency-powered darknet murder marts. Here's
a choice sample quote:

begin quote

16.10.4. Will I be sad if anonymous methods allow untraceable markets
for assassinations? It depends. In many cases, people deserve
death--those who have escaped justice, those who have broken
solemn commitments, etc. Gun grabbing politicians, for
example should be killed out of hand. Anonymous rodent
removal services will be a tool of liberty. The BATF agents
who murdered Randy Weaver's wife and son should be shot. If
the courts won't do it, a market for hits will do it.
- (Imagine for a moment an "anonymous fund" to collect the
money for such a hit. Interesting possibilities.)
- "Crypto Star Chambers," or what might be called
"digilantes," may be formed on-line, and untraceably, to
mete out justice to those let off on technicalities. Not
altogether a bad thing.

Attacking vulnerabilities in the bitcoin network seems like a great idea.

Yeah, the practice of extracting of patterns in software does refer a lot to A Pattern Language[0][1]. Admittedly I stumbled upon CA's work when I'm looking into building a design pattern for my current workplace. But it's a bit disheartening that currently CA is referred more towards the design and design system side of software instead of the building/writing, although patterns are still very much practiced.

Yes, but saying that the core tenet was lost is a bit dramatic. The guys working on it were still interested in other aspects of cryptocurrencies that bitcoin does not implement. Bulletproofs coming out in 2017 meant that Monero had inefficient fungibility and confidential transactions before, bloating the blockchain before they implemented bulletproofs.

There's so much stuff that still had to be researched after Bitcoin came out.

One big example that comes to mind is SegWit.

The cryptography was still not there and I do not feel that something can be lost if it's not there.
In case you missed it, Stanford administrators tried to deny responsibility when questioned why CXO level executives (who were working from home) got priority over front line workers for vaccinations blaming "the algorithm".

> According to an email sent by a chief resident to other residents, Stanford's leaders explained that an algorithm was used to assign its first allotment of the vaccine. The algorithm was said to have prioritized those health care workers at highest risk for COVID infections, along with factors like age and the location or unit where they work in the hospital. Residents apparently did not have an assigned location, and along with their typically young age, they were dropped low on the priority list.

> Stanford has not provided an answer to NPR's request for an explanation of its process or its algorithm.

> Neurology residents were among those who organized and protested on Friday.

> One neurology resident, who was involved in planning Friday's protest, said that a flawed algorithm is no excuse. She requested anonymity for fear of affecting her future job search.

> "[A]lgorithms are made by people and the results ... were reviewed multiple times by people," she wrote in an email to NPR. "The ones who ultimately approved the decisions are responsible. If this is an oversight, even if unintentional, it speaks volumes about how the front line staff and residents are perceived: an afterthought, only after we've protested. There's an utter disconnect between the administrators and the front line workers. This is also reflective that no departmental chair or chief resident was involved in the decision making process."

> I don't think that telling people what should they do with electricity is the way to go.

If the advice is sound, maybe we should be telling people about it. For example, we could recommend to replace cheap ineffective ACs with effective but expensive heat pumps and some small percentage of people will do that. But this won't do much to mitigate CO2 production. AC energy consumption isn't a major driver of CO2 pollution, fossil-fueled transport and coal/gas power plants are.
I feel like this guy has the whole thing upside down. He says the core issue is lack of trust. I'd say it was excess trust: I don't know anyone who watches fox news because they want all the facts and are mixing it with all other sources (because no one source is trustworthy). Rather, people blindly trust fox news because they're morons. The same applies to Facebook conspiracies. The capitol insurrectionists weren't there because they didn't trust millions of local election officials, all the main papers radio and TV shows.

They were there because they 110% trusted select twitter accounts (including the president).

People go on about young kids on social media. The real issue is older people, people with mental and social issues, people who are easily influenced.

I actually suspect the author is on that very list.

Ok, so this is a design decision problem. We can now go one of two ways

1. Leave it as it is. Tell patients * really loudly* it to put magnets near their chests.

2. Redesign the reed switch to use some RFID style interface so that only someone with correct password can adjust the device.

My take is 1.

2. Opens up a whole world of failure possibilities that are not easy to know or predict - and every day a zero-day is possible.

But 1. remains simple to understand and limited in the ways it can go wrong.

You may say that, but given that proof-of-stake coins should be able to easily outcompete proof-of-work coins on a purely technical basis, and yet they have not achieved that success yet in practice (although they are growing rapidly), it seems the overall market still disagrees.

I've decided to get rid of Amazon, and ebooks are one of the difficult issues.

Are there no independent sites like goodreads or LibraryThing left? I don't really need the tracking, but the discovery.

Also I have found that actually ebooks are sometimes cheaper on other places than Amazon, so a price comprison would be good. It could be integrated into a site like LibraryThings- LibraryThing already has it to some extent, but doesn't seem to include most vendors in my country (Germany).

Also there were other reasons why I didn't want to use LibraryThing anymore, which I have forgotten. I just remember that I didn't want to use it anymore some years ago.

My understanding of the space contradicts each of your points. So without either of us providing citations, both of our opinions are pretty useless to the casual reader. But I will add some thoughts here.

> The [humongous] energy wastage of the network should be the biggest cause of concern, but most proponents shoo it away by buzzwords like lightning network etc.

Lightning Network is a second layer payment network that is working today. Its goal is to take the transaction pressure off of the base layer (blockchain). Its design has privacy built-in, so it's not possible to generate statistics [3] on its total transaction thru-put. That's also why articles like the one on which we are commenting are so disingenuous. The source they cite makes a direct comparison of the total transaction volume of the Visa network with the Bitcoin blockchain while completely ignoring layer 2 networks built on-top of Bitcoin.

> Bitcoin is popular in the west and the US specifically because it lacks the cutting edge financial networks rest of the world has. Citizens in China, India, Kenya etc can do transactions in a jiffy using their existing bank accounts, whereas ACH clearance takes longer time.

Bitcoin is not "popular" anywhere. The total number of Bitcoin ATMs [1] and physical shops/vendors [2] transacting with Bitcoin is still quite limited. The vast majority of commerce occurs online. But what I do see is that there is slow, steady growth globally. The infrastructure is still developing to support larger volumes of users - and with more diverse levels of computer skills.

It's `pandas.read_<format> -> DataFrame` and `DataFrame.to_<format>`. So pandas reads a data format and gives you a dataframe. The `to_<format>` are instane methods of the DataFrame where you write a dataframe to a format. To me that makes sense.
The nonce-calculations are what makes bitcoin an energy credit. It's why it's a valuable digital asset and commodity. If it cost ZERO dollars to create bitcoin it would just be fiat... useless inflation adding zero value to current shareholders.

Bitcoin are being traded by energy companies to subsidize their infrastructure and improve energy efficiency and capacity.

In some ways Bitcoin is a battery, because hydro dams don't idle generators as often they can sell their excess energy production and subsidize the dry season.
Oil companies capture the natural gas flares and use it to power generators to mine bitcoin, etc. There really only needs to be one POW coin, and I think it's pretty obvious that Bitcoin is it.
It's obviously good if worldwide miners all agree to protect the environment together. It's also right that many governments have paid a lot of attention to Bitcoin. However, Bitcoin is not to be strictly regulated by design.

A government strong enough might have the ability to control Bitcoin mining over the holders, but breaking decentralization in this way will kill Bitcoin in its fundamental, and it seems that no such government is going to do this for now, especially when the reason is "environmental problems", which is generally not in high priority. Beside this idea, maybe a BIP (Bitcoin Improvement Proposal) is the best way of achieving consensus, but I can't imagine such a proposal being approved based on its limited feasibility.

Did he really blow his credibility though? There is a double standard at work. People who are generally honest and accurate only have to slip up a handful of times and suddenly are deemed non-credible. At the same time, in the same media venues, you have people who lie a dozen times a day and remain credible. I’m all for holding government officials to a high standard, but most of the trump administration would have been laughed out of the room had they been held to the same standard as fauci.

(5 * 3) + (3 * 2)

That's not that great, since it uses infix precedence - either explicitly (here) or implicitly. I need to read into it to understand that a sum is computed and I need to then find out the boundaries of the subexpressions. But the brain can be trained for that, just as it can be trained to read Lisp, Erlang, or even APL code.

Nested lists are the base for Lisp syntax. Thus numeric code is just like other ordinary code. Lisp was developed to also do symbolic computations: computing with expressions with symbols.

Thus to read Lisp you need to learn to read syntax based on nested lists and then numeric expressions are just an application of that. Still one is trained to do math with lot's of fancy syntax - fancy syntax you won't find in normal code anyway. For example the typical graphical root notation is mostly not found in programming languages.

If I (as a Lisp programmer) had problems understanding numeric expressions, I'd reformat them:

(+ (- a b) (* 100 (sqrt y) x) (* 50 (expt x 2)))

as

(+ (- a b)
(* 100 (sqrt y) x)
(* 50 (expt x 2)))

That's just another way to format a nested list.

The main problem is mapping that back to existing external forms which uses mixed infix/prefix/postfix syntax.

(a - b) + (100 * y^1/2 * x) + (50 * x^2)

Lisp allows one to compute this stuff:

CL-USER 18 > '#i( (a - b) + (100 * y^^(1/2) * x) + (50 * x^^2) )
(+ (- A B) (* 100 (EXPT Y (/ 1 2)) X) (* 50 (EXPT X 2)))

CL-USER 19 > (let ((*print-right-margin* 30))
(pprint *))

(+ (- A B)
(* 100 (EXPT Y (/ 1 2)) X)
(* 50 (EXPT X 2)))
Maybe if you are used to eating processed food, but as someone who almost always cooks meals from scratch, this list of ingredients doesn't look appealing. If I was buying a chicken breast, there wouldn't even be a list of ingredients.

"textured wheat protein" - no idea what it, but it sounds disgusting, and very highly processed. I'd presume it also contains gluten?

"potato protein" - again, it sounds like something highly processed.

"natural flavors" - it doesn't specify exactly what they are, so I don't even know what I'm eating - I don't like it.

"leghemoglobin" - you mentioned what this is, but otherwise it sounds like a lab-produced chemical.

"yeast extract" - makes me think of marmite, which is one of the most revolting substances on earth! Aside from that, I think of the smell of yeast; I... don't think I want to eat that.

"konjac gum" - never heard of it.

"xanthan gum" - I think it's some kind of thickening agent?

"soy protein isolate" - no idea what this is. The wheat and potato proteins don't have "isolate" in their names, so I assume this is even more highly processed. For some reason it makes me think of processes like "hydrogenation" - ways we mess around with foods to make them as cheap as possible, sometimes with negative health consequences.

"vitamin E..." - makes me think the raw ingredients on their own are so unhealthy that they had to add a few crushed multivitamins.

Overall: it sounds highly processed and devoid of nutrition. blech!
You’re making a great point there about procedural mindset being applied to array programming.
But the thing is, I feel like array based programming should lend itself naturally to functional approaches. And Pandas does do this to an extent.

My problem is that this is super inconsistent. Some things are done as a method call on an object, others by passing the object to a pandas function and others yet by passing a function to a method on an object. This is the major source of frustration for me.

Maybe there is some logic to that, but I haven’t found it yet and I think that is a sign of bad API design. Its like PHP to me. All nice and documented but useless without Googling everything
It's hard to say. There are lots of things we make kids do that are good for them that they'd never want to do on their own, like go to school, do their homework, eat their vegetables.

And with something like music, it takes a lot of unpleasant effort and hard work initially before it hits a point where you really can start enjoying it. But kids would never have experienced such payoffs before, so having faith in perservering seems impossible. So one could argue that forcing a kid to commit and invest until they see the payoff, is the only way they can make a truly informed decision.

Or we can have faith that kids are a lot more mature and wise than we think. And maybe they've already seen all the way into the future and the end result. Or there is a different passion that they'd rather pursue.

Bitcoin UTXO
Undoubtedly, dozens of sources for information retrieval in terms of bitcoin and cryptocurrencies exist.

However, most of those platforms focus on news rather than on providing serious information. Thus, common questions regarding the core principles of bitcoin and other cryptocurrencies remain unanswered for the public.

One essential question always related with the term "HODL" are the bitcoin unspent transactions (UTXO). Since the specific question of "how can I measure bitcoin hodl mentality" always appears, I wanted to share this article.

According to my opinion, it explains well what Bitcoin UTXO is, how HODL waves can be described and more general how bitcoin transactions are designed.
