From what I've seen I came to this conclusion (further input from HN readers gladly accepted, maybe I got something wrong): It seems that yesterday at around 01:00 UTC, someone with a huge amount of cash on GDAX started a buying bot, w

Not if there isn't an interface. If I create one, sure, but then I would have to do that on all dev computers as well and I'd have to forward the address somehow into all server and client configs and/or command-lines of tool

True, but the number of weird mistakes due to floating point inaccuracies that happened in Excel spreadsheets is probably too large to be accurately representable in a 32bit float number.

Thanks for the detailed explanation of your thought process. I guess you fall into the few percent of developers who are NOT meant to be addressed by the general rule of "don't use float for money". Like with all "genera

You could argue that ICO-style crowdfunding is the only one of these problems that's currently not solvable in any other way, purely because it's impossible to get other people to invest obscene amounts of money into dubious proje

Providing a decimal type would of course not be the job of the developer of a smart contract - I would expect that the smart contract platform would anticipate the necessity of convenient decimal number handling and thus provide a suitable

Don't worry, I'm sitting in the same boat ;-)

So true. Whenever stuff gets "convenient" for me as a developer, I ask myself what the downside of this "convenience" for me is that will have to be endured by others. Often times it's inconveniences for the guys wh

Theoretically, this is true. The value, and hence the price, is splitted. But markets are not perfectly efficient, and Bitcoin markets in particular are very inefficient and totally driven by psychology, particularly speculation and greed.

True, but unfortunately you'll need the services of an exchange if you want to short. Longing is possible by putting cryptos in a wallet you have the private keys for, but not shorting. As I think about it, this is actually another ben

You can short Bitcoin (with respect to USD or other cryptos, but I assume you're interested in shorting BTCUSD) on pretty much all the bigger exchanges. Bitfinex offers it, Kraken too. You'll have to pay a lending fee for the BTC

No, this function (the init function) was public for a reason - it must be callable by anyone, since it's the thing you call when you want to create a new wallet! And the kill functionality has been non-public, it required the caller t

> That's not correct. There is a construct "library" that is different from a normal contract. But the code in question didn't use that (for whatever reason). Thanks for pointing me to this! Didn't know that yet.

If I get this correctly, this is what happened: The parity wallet uses a "shared library" in which the actual logic is implemented. All individual wallets have their own data storages and coin balances, but contain just a little b

The code is immutable, but Ethereum has a functionality called "suicide" by which a contract can, well, commit suicide. It is kind of like a deletion, in that the code can't be executed anymore afterwards, but of course the b

I am wondering what exactly has been the point of having this code separated in this "library" in the first place, instead of just duplicating the code for each owner of a multisig wallet. It can't be to ease the update proce

I would say the relationship is this one: First, Ethereum was found to be the perfect Ponzi scheme platform by dubious “ICO“ initiators. Then, early investors made a huge bunch of money on these ICOs. Then the price skyrocketed, as more peo

It's not even only Apple anymore. As far as I have seen, the Microsoft Surface Pro suffers from the exact same limitation. Practically every manufacturer who wants to build some high-end, but still thin and lightweight laptop runs into
