1  Local / Skandinavisk / How is life in Sweden right now ? on: November 09, 2020, 01:03:31 PM
Hi, I'm French and here we are explicitly forbidden to go out unless you wear a mask and fill a form to justify why you leave home.

I'm told you guys are basically free to live your life more or less normally, is it true ?

3  Bitcoin / Wallet software / Possibly improving on BIP039 with language models ? on: October 27, 2020, 10:15:39 PM
These days, artificial intelligence is all the rage and the latest kids on the block are transformer models, and with them language models such as GPT-2 and most recently GPT-3.

These things are pretty cool, with them you can create texts that are often indistinguishable from a text written by a human.

This leads me to wonder if these models could be used to improve on BIP039.  I wouldn't feel confident in using BIP039 to memorize a private key.  The generated words are very random and uncorrelated, it seems to me the risk I forget them, or forget their order, is very high.

That's why I wonder if it's possible to use a private key to seed the word completion algorithm of a language model.

That doesn't seem obvious to me, as the probability distribution for each new word is not uniform, so we can't just pick say the residue modulo ten to pick one word out of ten possible ones.

Yet, my intuition tells me it has to be possible to sample the words while respecting the probability distribution.  I just can't quite figure out how exactly.

If someone sees how this can be done and can provide a demonstration with GPT-2, that would be fantastic.

PS.  I mean think about it : GPT-3 can generate poems, for instance.  Wouldn't it be cool if you could encode a bitcoin private key in a poem ?

I wish I was better at C++ programming.   And basically I wish I had worked harder at school so I can have a PhD...

But if you're not like me and you know C++ well, if you live in Europe, if you're looking for a job, and if you have professional experience in software development, you may be lucky enough to work for one of the most ambitious scientific endeavor of this century.

12  Bitcoin / Press / 2013-06-07: Palmer Luckey mentioning bitcoin on: June 07, 2013, 10:53:39 AM
Not an article about bitcoin, but a mention of it by Palmer Luckey, creator of the Oculus rift, Virtual Reality Headset for gaming.

Interviewer: I never really “got” Second Life. Minecraft, I can wrap my head around quickly. But Second Life …

Luckey: It’s very difficult to get into. There’s a steep learning curve. The last time I went into Second Life was to buy bitcoins from a crazy guy who was selling them below market value, but you had to go into Second Life to meet with him.

It's one of those still rare articles where I found a mention of bitcoin by pure chance (I was reading the article because I'm interested in the Oculus rift).

14  Local / Hors-sujet / [vraiment hors sujet] apprendre la bioinformatique en ligne sur on: May 10, 2013, 01:28:48 AM
Depuis tout petit vous êtes passionné par la biologie mais manque de bol vous êtes devenu informaticien?  C'est pas grave, vous pouvez encore devenir bio-informaticien   Cheesy

Plus sérieusement, je voudrais faire un peu de pub pour cet excellent site qui permet d'apprendre la bioinformatique en ligne:

Bon je ne sais pas si on peut vraiment apprendre la bio-informatique comme ça (j'en doute un peu car personnellement j'ai tendance à tout oublier une fois que j'ai résolu un problème), mais en tout cas c'est assez passionnant.   Bref si la biologie et l'informatique vous plaisent, que vous avez du temps libre et que vous aimez vous creuser les méninges, vous devriez vous inscrire et participer.

A simple poll to see what bitcoiners think of space exploration in general and SpaceX in particular.

I like this prediction because it's very easy to settle.  Whenever EM will have finished living (as late as possible as I don't wish him no harm), we'll know.

20  Economy / Economics / Price stability is price control on: April 11, 2013, 10:02:16 PM
The prominent objective of most central banks is price stability.   I think this is wrong, just as wrong as price control is.

Sure, price stability for any entrepreneur is convenient and desirable.  It's very much necessary in order to plan for the future, decide wages, choose investments and so on.

But the very point of a price is to vary in order to transmit economic information.   If the prices are stable, it is supposed to mean that the economy is stable.  Now look at the world around you and tell me:  does the economy look stable to you?

I understand that price stability is something people can desire.   But so is nice weather.    And yet everybody knows that we need crapy weather and most importantly rain from times to times.   Prices are not supposed to be something we control, like in some communist country.   Price is something that is supposed to tell us something about the state of the economy.

When the price of all things increases, it is supposed to mean that for some reason the economy is not doing very well:  producers have difficulties responding to the demand.  As a consequence, people start to save things, to consume less.  They spare means of production and reduce their demand.  Also, entrepreneur think harder on how to increase production.   This reaction provides a negative feedback which tends to counter the price increase:  the system then tends towards equilibrium.

When the price of all things decreases, it is supposed to mean that for some reason the economy is doing fine:  producers are easily capable of meeting demand.  Stuff are easy to make.   Or it just mean that people don't need what producer are producing anymore.  Then factories hire less and that can lead to unemployment.  But that is economic reality:  there would be no point hiring someone if it is to produce something that people don't want.

Anyway, my point being:  prices are an economic indicator.  Messing with money supply in order to artificially make this indicator stable in time is very wrong, if you ask me.
