Cynicism and emotional hyperbole are some of the less appealing and helpful human traits.

Given the choice of being around lifelong cynics who think people ought to act the way they think AND vegetarian, or people who have a positive mindset and snap the necks of rabbits and shoot deer every weekend, I'll take the rabbit killers every time.

When I was younger - I thought I was smart because highschool teachers are not terribly bright. Then I got out into the real world and realized a thing or two.

When you're a cynical crybaby in school - they have to put up with you. When you're a cynical crybaby out in the real world, you'll be alone writing things on the internet because nobody wants to hear it, or around other losers, complaining about how everyone else is doing it wrong :)
What do you think is the best way to store+exchange value across borders in a way that can't be censored or reversed by any third party and doesn't require trusting or asking permission from any third party?

> Gold requires hundreds of dollars per ounce and untold energy to extract.

A valid comparison. Gold mining is spending resources to increase the amount of gold in existence, without delivering any other value.

> U.S. dollars require the existence of a powerful economy and trillion dollar military to keep the currency secure and desirable.

Not a valid comparison. Outside of a few relatively inexpensive activities at the US Mint and inside banks, no resources are being spent specifically on increasing the money supply. The value of the dollar is the byproduct of economic activity that exists primarily to achieve other things.
The consensus on the Haskell subreddit was that the Haskell Wikibook (https://en.wikibooks.org/wiki/Haskell) has gotten even better than "Haskell Programming From First Principles".

In any case, that book ain't bad either. It's better than Learn You A Haskell.

I also like "Discrete Mathematics Using a Computer" (https://github.com/ryukinix/discrete-mathematics/blob/master...). It focuses on teaching discrete mathematics and introduces some Haskell as executable mathematical notation on the side.

> compare the cost of Bitcoin to U.S. dollars or gold

All-in sustaining costs for mining an ounce of gold (worth $1,293.70) is between $1,100 and $1,200.
Still, there is a fixed amount of hydro power available, short of building new dams. This puts Bitcoin's toll on fossil fuel.

(If Bitcoin didn't exist, the hydro power would still be there and would be used for something else, therefore less fossil fuel would have to be burned in its place.)
Large transactions are not sponsoring small transactions. Transactions are priced by their size in bytes, so the monetary value of the transaction is totally irrelevant to the fee.

People holding bitcoin are essentially sponsoring all transactions, if you want to look at it that way, because miners are making money both from fees and from new bitcoin that is created, which dilutes the value of all existing bitcoin.

Creosote is amazing! It's responsible for that "desert rain" smell. There is also King Clone, "estimated to be 11,700 years old, making it one of the oldest living organisms on Earth" [1]

If read the article correctly, he's including the cost of mining Bitcoin, not merely energy cost to verify a coin (which is absolutely trivial). Once all Bitcoin is mined (yes, there's a built-in maximum), or it becomes prohibitively expensive to mine, there won't be any mining costs.

You can look at the current Bitcoin energy costs as the startup cost to establish a new gold mine or a new country with its own currency.
I don't know Racket, nor Chez Scheme, but I've been wanting to learn one or the other. Now that Racket will just transpile to chez scheme, what's the advantage?

Is there any reason for me to learn Racket instead of chez scheme?

Like there's good reason for using Elm, TypeScirpt, Clojurescript over JavaScript directly. Or F# over C#, or Clojure over Java, etc. Is there similar advantage for Racket over Chez Scheme directly? At first glance it feels to me like no. Like the overhead of Racket not being the first class language of the backend might be a worst con then the slight language features it might have over Chez Scheme (if any). Is that true? That's what I'd like to know.

Thanks.
I'd say stick with Rofi. I had considered moving to it but dmenu2 just works well enough for what I want it to do to bother switching. If I was certain I wanted more features, I'd go with Rofi.

According to this it costs almost 21 cents to "make" a dollar of bitcoins. According to the mint's 2015 annual report[1] they made 1,114 million dollars in circulating coins at a cost of .51 cents per dollar in coins.

However bills cost 4.9 cents/dollar for $1 bills and half a cent per dollar for $20 bills. So the vast majority of money is much, much cheaper than a bitcoin.

That was definitely the intention. It was intended as a systems and application programming language for the Newton.

The original Apple implementation compiled to native ARM code. The runtime was intended to be competitive with C, but by the time we approached that target, large parts of the toolbox had already been written in C, and Walter Smith had created NewtonScript as a scripting language that worked as an alternative for non-performance-critical code. At that point the Cambridge team re-targetted the implementation to build Macintosh applications, but that wasn't a sufficiently compelling (to Apple management) use, and we had lost our executive sponsor when the director of the Apple Cambridge lab was promoted to a position in Cupertino.

For those curious about Dylan's history, the Wikipedia page https://en.wikipedia.org/wiki/History_of_the_Dylan_programmi... looks correct.

(I'm the “Oliver Steele” mentioned on that page. I went to Apple Dylan from Skia – later released as Quickdraw GX – another technology that missed the Newton boat.)
Yes, things are coupled, but they are still malleable. The F-82 fuselage was longer than a normal P-51 fuselage by almost 5' (57 inches). They stretched the section behind the cockpit, to give it more room for fuel tanks.
My perspective is this:

A lot of people got a lot of productive work done 'hacking' together jquery and jquery-ui scripts. The result wasn't pretty and was a bit of a maintenance nightmare.

They are not only a bit of alienated by having to work with frameworks, but they're expected to be as productive with these frameworks as they were hacking together jquery scripts and snippets, but are still the 1-man or 2-man developers within a wider business.

These frameworks are great in a business built around the web such as a SAAS business, but a lot of people are in businesses where their saas part is secondary, or are trying to maintain sites which just aren't the main product of the business.

They're pressured by well meaning but often misguided higher-ups to use the latest and greatest and feel the pressure of churn.
It's worth noting that this Bitcoin Energy Consumption Index (BECI) is not without controversy. A more detailed analysis is this one:

http://blog.zorinaq.com/bitcoin-electricity-consumption/

and the author of that has specific criticisms of the BECI calculation:

http://blog.zorinaq.com/serious-faults-in-beci/
What the article fails to take into account is the huge volatility of BTC relative to the USD. So if you are going to make this calculation over a whole year then you have to split it up into many small calculations (for instance, per block with the going rate of BTC:USD at the time) and then accumulate in USD.

On another note: a very large fraction of all bitcoin mining is happening in China and electricity cost there is quite different compared to the USA.

So I seriously question the prime assumption leading to the quoted energy consumption.
Although, I like their service - just uninstalled. Peace.

Didn't even realize this was happening until this article. But seriously, we should consider enacting laws against this. For advertising purposes they shouldn't need anything more than a city location. Even then, there should be an option to turn it off.
The energy expended is a guarantee of security and immutability.

The fact that real world energy is expended is the thermodynamic guarantee of the irreversibility of a transaction.

If you have access to the VISA database, and change something, you cannot have the cryptographic proof that it has not been tampered with. At the very best, you trust a VISA root key.

With Bitcoin you trust math and physics, telling that if the whole network has expended 1TWh after my transaction, at least twice that energy will be necessary to reverse it, and the only data i need to prove that, is the blockchain.
For a fair comparison we should look at "energy" in an abstract manner. Time and money is energy too. Every time gold exchanges hands, it also costs energy.
Note that bitcoin mining does not primarily exist to increase the amount of bitcoin in existence. That's just part of the incentive to mine.

Bitcoin mining exists to timestamp transactions so that the network can achieve consensus on the state of the ledger. It is designed to use as much energy as possible, so as to make it expensive to cheat.

I think this is a good start at looking at some of the human factors issues with menus but it doesn't even seem to get out of the "known issues" on to something more.

Menus have been an issue for a long time, ever since XDE[1] at least. The original Mac "global menu bar across the top" was one shot at it, Xerox (and XFCE it seems) had the menu popup when ever you hit the right button. Windows of course had the 'start' button which did a 'menu reveal'. But there are other interesting ideas in menus as well. One of my favorites in terms of ingenuity were the pie menus[2]. I saw a demo which I believe was Don Hopkins work and it demonstrated how quickly and accurately you could select things. That speed and accuracy derived from converting menu disambiguation using a bunch of possibly overlapping rectangles, to using only vectors from the current point.

One of the challenges that has added to the problem has been ginormous screens. When menu metaphors are attached to the physical screen boundaries the amount of mouse movement needed is quite large. Of course with touch screens it is compensated for by just moving your finger, but as we've seen on iPads and Surface Pros that can limit menu density due to fat fingers :-)

The Bf-109Z, which never flew, was the same kind of idea as the F-82 but only had one cockpit (on the left side), for that same sort of asymmetry.
So, if you look just at transaction cost the system clearly cannot sustain itself. But as more people buy into BTC, the system keeps from collapsing. If you ask me, that's starting to look like a Ponzi scheme in disguise ...

Hello Hacker News community,

https://www.brunoe.com is a location-based search and comparison tool.

It searches housing options from different sources at once and allows you to compare the listings based on price, distances and other options on a map.

For example, you will be able to view a particular apartment in San Francisco and see ads from Craigslist, Facebook Marketplace and other home-share/roommate startups -- and compare its offerings and prices against each other or the traditional rent prices.

As of writing this, the app has just gone live. So right now there isn't a lot of listings yet (just a few dozen in San Francisco and the Bay Area). However if you feel nice, you can help me by clicking the "Add Your Website" button. Just put the URL in there and the listing will get indexed onto the app.

The goal of this tool is to provide the best ways to compare the offerings from all housing listings and help you discover new housing options that you may not have thought about (such as home-sharing or living in an airstream van).

In the next coming days, as I continue to work on the crawling/indexing system and process, the listings in the SF/Bay area will become populated pretty quickly.

I look forward to reading your feedbacks! Thank you!
With cars, at highway speeds, you're right - but engine noise is a much more significant factor for motorcycles (some of which are absurdly loud) and heavy trucks/buses.

In built-up cities, like London, these vehicles are usually traveling at relatively low speeds anyway, so it's really engine noise that is the problem.
This is a stupid comparison. The number of transactions can be increased by a factor of a 1000 easily while holding the amount of energy expended constant.
I use Vue. I'm not convinced it needs an alternative. It's plenty fast - more than fast enough IMO, and fairly lightweight as well.
This is very wrong. It does not work that way at all.

Volume or value of transactions has nothing to do with the energy expended.

The energy is needed to calculate a mathematic proof that makes sure your transaction cannot be reversed or tampered with.

This mathematic proof on average is calculated every 10 minutes, with no correlation to the number of transactions.

You make a transaction, and if the bitcoin network has expended 1TWh after you sent it, at least 2TWh are needed to reverse that transaction (and/or any other transaction). You can see how over time it becomes impossible, even with unlimited money, to reverse one.

Arbitrary priors are magic numbers.

Is there a frequentist statistic that can be used in a deterministic function to determine which arbitrary priors to use?
It's far fetched, there's a broad spectrum of systems one can fit the same metaphor to, and like those systems it offers no insight about them.

What is the conclusion and what does it mean for blockchains? What is the benefit of modeling a blockchain as a living organism?
Thanks. I did know that about Java (having used it), just that it was not clear to me from your earlier wording, that that is what you were saying. NP.
I get that the energy is being used for something useful and cool, but when the energy cost to secure a single transaction could power 5 households for a day, then something is wrong and needs to be fixed.

Surely even fans can agree there's a level at which it just doesn't make sense any more.

I was saying we should be concerned when a site can be taken down and the domain seized without further information.

You state that it happens 1,000 times a day. You certainly know more than me on this, but in these cases is the domain frozen or seized? It just seems there was more to the story than was told.

>Bitcoin however is money.

Bitcoin is not money as we think in a modern way. If you think of money a way to exchange goods then yes Bitcoin is money.
Modern money (printed piece of paper labeled in currencies in its materialized form. Just a sequence of digits on your bank account) is dept. That's why currencies have interest rates (IR). It is also possible to create money out of nothing.
IR and volume are adjusted according to the economy. Bitcoin is closer to a commodity in the sense that it is finite and requires work to be extracted.
Question: How do you present the user with a list of all the applications on the computer?

Answer: With a list (of icons + text) or list (of icon tiles) or a couple of lists (same as the others, split by categories.)

You can slice and dice things however you like, but you are fundamentally presenting a list of things, and I don't think we can fundamentally improve on the process of presenting a list of things above and beyond literally showing lists of things.

Search-ability is great, but it is only good for people who know the names of the programs that do what they want. Icons+text are compact, but don't give any indication of program functionality and don't scale well. Categorized lists give both names and indication of program function, but require more user button-pushing to find the program they want.

I think the only real improvement possible in this field is an application search function that lets user search for what they want to do, rather than for specific applications.

If the author wants to find a more realistic opportunity for improvement in the "show all applications" direction, he should look at the "help" command output, as compared to compgen -c.

> the energy cost of bitcoin is ongoing and depends on the volume of transactions

Wait, what? That's not correct at all.

The energy cost is based on the "difficulty", which is derived from the moving average of the hashpower in the network. Bitcoin effectively forces the network to take a specific amount of time to mine a block irrespective of the number of mining nodes. The transaction volume has nothing to do with it.
> Once all Bitcoin is mined (yes, there's a built-in maximum), or it becomes prohibitively expensive to mine, there won't be any mining costs.

In that future you will still mine blocks, but there won't be any new bitcoin generated in that block. Sure, you might want to use a different word for that than "mining", but it will still have very real and significant energy.
Isn't there software on the Tesla that throttles back performance if you launch it enough?
Your assertion that giving an opinion without supporting evidence is automatically "textbook flame-war starting" is also patently silly.
> If Bitcoin didn't exist, the hydro power would still be there and would be used for something else

That's not a good assumption. There are many power plants in China in the middle of nowhere unconnected to much. It's completely plausible that the entire bitcoin network could run on clean energy that otherwise couldn't be used for much else because it's too remote (geothermal in Greenland or something).
