Put aside for a moment the name for the 'scheme' and consider the mechanism design differences between USD and Bitcoin: - USD is needed in order to pay taxes on the US, but can be printed arbitrarily by a centralized mint. - Bitco

I think the reference to retirement funds is in relation to the fact many of them are under collateralized. They need to take new investor's money to pay out old investors. Some more background here: https://www.google.com&#

Hey dweller! That isn't the mechanism. What happens instead is akin to an endowment for payment of storage. An outline is found here: https://www.arweave.org/faqs.html#what-is-a-storage-endowmen... And the paper has th

Thanks for the comment @blacksqr! This calculator is outdated -- the current price of storage oscillates around $0.01/MB. The maximum single chunk size is also 10MB now, and you can send as many chunks as you like.

I think the HN crowd has always been interested in this sort of stuff? It certainly has since I started reading it (~7 years ago). One of the things that I like about HN is that we are not completely inward looking. From the guidelines: &gt

Hi, Thanks for your thoughts. As I have stated elsewhere, the code handles all of the cases I needed it to handle, due to the stability of the input file format (which was emitted from another program). I don't see that this should be

I submitted that edit before the post had any replies. Also, I did try to make clear that the given code was created 'for a specific use case in which I knew' that the format of the input files was tightly defined.

This is interesting, and as the other commenters have pointed out, creating a parser for /all/ variations of CSV can be very tricky.

by samwilliams 10y ago
Ah right, yes, I can imagine that would be extremely messy!

by samwilliams 10y ago
That is very interesting, thanks! I hadn't thought about Unicode or tolerating human error. Although the times I have worked with it have been when it is a transport medium between two computer programs.

Do you mean Excel to CSV? Or a CSV importer? I totally agree about Excel importing, but CSV is trivial, no? Here is an Erlang version I happened to write yesterday: lists:map( fun(Row) -> string:tokens(Row, [SepChar]) end, st

This is very neat! I created an Erlang script that allows you to send messages by morse code to the keyboard like this: ./remote_morse "HI,IAMSAM." (Spaces don't appear to be used in morse code?) The messages won&

Do you mean with the 'little book of OS dev'? Or one of the other resources? In general, my experience has been that OS dev is a topic that is best approached through the study of a variety of different documents, simultaneously.

Thanks! At the moment, the best source of information is the talk I gave at the Erlang User Conference 2016 [0]. Four papers and a thesis are in the pipeline for next year, though! I will update the site once PDFs of those are available. [0
