"Scanning blockchain" takes ages (over 10 minutes).
Is there any way to speed it up?

On the 11th of Feb we r launching public test of Asset Exchange. Do we have at least 1 client ready for that? What platforms does it support?

I will probably start implementing on 11th, so I won't make it.

worked MUUUCH faster for me than all previous versions...

James, how does this affect the status of your VM bounty?

It seems to obsolete it
I think zahlen was the only one who spent time on it
If it is ok with him, i would like to authorize 500 nxt for his troubles

Wasn't any trouble, it was fun revisiting a topic (computability theory) I hadn't worked with for a long time. I'm always ok with more nxt though Thanks a lot!

Earning Nxt with doing something you like is great, isn't it?

It's awesome!
First time getting paid by doing 3D work, the work I like very much.
The rest is very technical for me, but I read all the posts here anyway  

Congrats! Yeah, it's really awesome to get paid with what you're working on. I wonder if this is how folks who get paid in shares feel? (I'm definitely looking forward to when our "shares" take off )

Btw https://i.imgur.com/Bz6KfAv.jpg is amazing! The texture feels textured in this version. I didn't like the marble texture much.

Question:
Is it better to give 5, 10 or 20 Nxt to little good things you see regularly (expecting everyone else to do the same),
or;
Will people think that is insulting for their effort (maybe get pee'd off and stop helping?) so I should save up my Nxt till I see something "WOW!" and give a few hundred?

I've gotten some small donations and one large one. I appreciate them all the same.

Yeah, I wouldn't feel insulted if I were given 1 nxt, I'd appreciate the gesture.

(This is the cue for everyone to start tipping me )

I'd love it if there was a way to include a message along with the tip. This is a given in doge tipping on reddit, since the tip bot works via replying to who you want to tip, should be the same way for a nxt reddit tip bot. Would also be natural thing if a site like a forum could integrate a more general tipping software and API. tipnxt.com already has this feature.

Too bad it's always at time we have dinner here. My wife wouldn't be happy if I play...

I've started a section on the wiki for organizing our projects. In particular, check out the List of Proposals and Bounties page. I'm thinking we could link to stuff that is "active" there. That could be links to forum threads, google docs, or other wiki pages where projects are being discussed and hashed out, and project statuses are being updated.

For a good example of this, check out the wiki page for the new address format using Reed-Solomon encoding that NxtChg started a long time ago. Very clearly organized.

My thinking is to use the Discussion pages for throwing around ideas, criticisms, suggestions, etc, and use the main pages for summary of the proposal/project status.

Not enough folks are using Discussion pages . Click on this tab more often:



James, this could be the right place for you to put up your (many, many!) ideas for comment. EvilDave, you could put your carbon offset proposal here too. Lots more projects that I don't remember (this is why we need to put all of them in a convenient place).

Pin, maybe it could be easier if you got everyone to post their projects on the wiki instead? Then you can just go through a list of links.

Don't worry about messing things up, it's a wiki, everything can be reversed. And don't worry if you don't know wiki formatting, just type/copy and paste. Other people can help you clean things up. If there's demand, I'll put up a quick guide to simple wiki editing.

I'll be technical support. Anyone has a problem, e.g. getting errors, can't figure out how to do something, ask me and I'll troubleshoot.

"Scanning blockchain" takes ages (over 10 minutes).

It seems to depend very non-linearly on the amount of memory. I don't have a better solution yet other than just making sure you give it enough memory. For me anything above -Xmx1024M works fine, 768M is slow, 512M crashed after more than 10 min of high CPU load. It is strange because last week I was able to run it with only -Xmx256M. These are the timings I get now:

-Xmx4096M:   55 s
-Xmx1024M:   58 s
-Xmx768M:     2 min 26 s
-Xmx512M:     > 10 min, out of memory

Anyway, why are hallmarks encoded to an ip address? A big problem for dynamic ips. Why not a private/public key pair with public key signed by an account?

I would like a mechanism like that. Maybe, hallmark is the wrong name though.

PUBLIC MATH SERVICE ANNOUNCEMENT

Can someone explain how he found out the passphrase of the genesis account?

    "It was a bright cold day in April, and the clocks were striking thirteen."

It has 14 words and some punctuation. Ignoring the punctuation and using a simple 2000 words long dictionary (and this is tiny! There are 1013913 words in the English language) we get 2000^14 possible passphrases, or about 10^46 possibilities, if we go by characters from the alphabet, it has 26^72 ~ 10^101 possibilities. A password written in base 58 and 26 characters long is also about 10^46 possibilities. In comparison, a random 8 character long password takes 3 hours to crack on a desktop pc. 9 char -> 3days, 10 char -> 1 year, 11 char -> 48 years. 26 char -> An octillion years.

Now it is a given that the entropy of a random password is much higher than that of a phrase from a novel, but I still can't see how he could crack the passphrase unless the entire thing was already in his dictionary! Let's not forget he was using a python script which is notably slow!

You've answered your own question An earlier poster linked to an Ars Technica article explaining this approach to password cracking in more detail.

Lots of people have already replied to this from the security perspective. I'm replying to this from the math perspective. Math is not simply about crunching numbers to get answers, it's really about reasoning and proof. This reasoning usually takes the form of

If (certain conditions hold), then (certain things must be true).

A lot of the 'math' I've been seeing lately forget to check that the conditions indeed hold. When you make a claim, and want to convince other people of that claim, the burden of proof should be on you to establish that the conditions hold, and that your claims follow from those conditions.

This is time-consuming though, we can't always reason through everything from basic principles. It's very tempting, and for little things more practical to just intuit/jump ahead, I'm often guilty of this. But we should keep in mind that if we jump ahead like this, we can't be certain our claims are correct

In service of math, and consequently the public.

Running 0.7.1 since release no probs with -Xmx500M

edit: not forging though

[smartwart]

version 0.7.x runs stable for me.
JL ,  you bring it up to production state, step by step.
Keep up the good work!!!

+1 IMPORTANT that would be more clear and more real

seems to be pretty stable for me as well.  did get this though:

0.7.1... believe that this will work on a dedicated server?



the 0.7.x version is a bad idea!

Oh well, no raspberry  anymore 

It will only work with it when starting without db and build it new. After restart its not working anymore...

odroid:
-Xmx1024M: ~5min
-Xmx512M:   ~25min but starting
