1  Bitcoin / Electrum / Key stretching weakness on: November 11, 2013, 07:51:19 AM
I found a small weakness in Electrum's key stretching algorithm: The seed-key is only hashed twice.  This allows rejecting most passphrases before stretching.  It's good for about 8 bits worth of security.

I have sample code here:  https://bitcointalk.org/index.php?topic=85495.msg3546401#msg3546401

If you fall on hard times, your family helps, your friends help, your neighbors help, your local community helps.

No, they do not.  A lot of people fall on hard times and nobody helps.

I do my part.  I've taken people into my home until they could get back on their feet.  I've paid hospital bills.  I've bought the medicine to save someone's life.  But it's not the norm, and so much so that when helping people I frequently get asked, "Why are you doing this?  What's your angle?"  There's no scam, I'm just doing what's right, and people cannot believe that's the case because they've never seen it happen before.

People should be entitled to a minimum safety net.  Food.  Shelter.  Health care.  Education.  From there, go earn the rest of what you want.  Having those things as a given makes people more productive because they'll start ventures that they could not risk if they were afraid to quit their job and lose their insurance, or be afraid that they'll starve to death if their business fails.

And when people who have pledged their eternal souls to helping those in need give up on you. Well then...

Apparently those people are enormous hypocrites.  Last I heard they'd only covered about 10% of the bill.

You know what's scary about leftists who give organizations nationally critical responsibilities? They fuck up in massively catastrophic ways.

This is not a "left" problem.  This is a "corrupt politician" problem, and they're available across the spectrum and from all parties.

I'm not saying that to defend the left.  I consider myself neither leftist nor a Democrat.  I own too many guns for that.  Smiley  And I have a load of other issues with the Democrats, but I'd rather not divert there.  In many issues I swing libertarian, but I don't take that label either; they foam at the mouth when I talk about social safety nets.  The fact is I have complex views that defy all the common labels.  Anyway, my point is that I'm pretty neutral, and not just knee-jerk defending one side.

For christ sake people got loans for 9X their annual salary with no money down. Terms that didn't even required them to pay the full interest on the loan! Your folks (leftists/liberals/socialists) made me guarantee these anonymous "sweet heart" loans.

This isn't leftists/liberals/socialists.  This is immoral bankers who bought corrupt politicians (across the whole spectrum) and created a system where they could make money by creating piles of terrible loans, skimming off some fees, and dumping them before they ended up with any responsibility.

This was never about helping people get housing.  That's the cover story, but it was always about making bankers rich.

And you are asking me to feel sorry for the defaulter you shouldn't have given the loan to.

I ask no such thing.  They fucked up too and bear the moral responsibility for taking on debt they couldn't possibly pay.  I don't feel sorry for them.  They were being irresponsible too, so fuck 'em.  I still think they're entitled to have some kind of cheap roof over their head, but they deserve to lose their house and go spend some time in the projects until they can get their act together and start paying for something better.
3  Economy / Economics / Three months in retrospect on: September 15, 2011, 07:09:43 AM


I'm not a technical analyst, so I won't speculate on the future.  This chart was just for my own education while considering the events of the last few months.

I'm comfortable calling Aug 6-9 a false break.  I think it was just MyBitcoin wallets getting dumped (and perhaps the stolen coins getting dumped; what ever happened to those?).  Then the trend resumes.

The resistance line is drawn in a bit optimistic.  I'd fix it but it doesn't really matter.  Just imagine it a few pixels down.

Aug 3-4 is interesting.  Was the memo released earlier than I have it marked?

4  Other / Meta / Mail config problem since restore on: September 12, 2011, 03:13:43 AM
Ever since the forums were restored after the hack, email from the server has been using 'daemon@bitcointalk.xta.net' for the envelope sender.  bitcointalk.xta.net doesn't exist, so mail is getting rejected, probably for a lot of people who want to do password resets, new registration, etc.  Before the hack the sender was 'www-data@bitcointalk.org'.

Here's someone else having trouble:  https://bitcointalk.org/index.php?topic=43515.0
