1  Other / Off-topic / optical media "raid array" on: May 12, 2012, 05:22:41 PM
Well, once i saw that blu rays are now cheaper than hard drives by around $0.02 per gig, this made me want to do something like raid with them.

I do not want to hook up multiple blu ray drives to be raided together, i want something that will take data and make a parity file or something that i can burn separately to other dvds. i would likely be zipping all the files together, encrypting them, then splitting them into seperate 10-20 gig files, likely 7z files.

Does such a program exist?

Some reasons why this might be better are

cheaper per gig
no risks associated with the data being connected to an outlet
no risks (significantly less) from software hardware failure associated with always being connected
the media is separated, so you can distribute it to different locations and not have to have it in 1 spot

So is this idea good or bad, and is it possible? what are possible problems. i am currently using ubuntu, so is it possible some snazzy stuff already exists and its just a matter of typing it in?


nvm, its called Parchive

some pretty good ideas so far. the ideas of using already existing numbers on common objects are interesting.
3  Other / Off-topic / keeping text on person on: May 01, 2012, 12:48:37 AM
Well, as we all know one of the number one concerns for cryptography is having keys and other information properly protected with a strong password. and most people are not able to remember or do not want to remember a strong password. So my question is, where is a good place to keep a small bit of text on your person at all times.

The location would preferably not be in clothing, but here is a list of some things i thought of off the top of my head.

container in mouth
ankle bracelet
thigh strap
a hole you put in some part of your body to hold small things
rfid implant in hand (coupled with [inconspicuous] Faraday glove.)

so what can you guys think of, or what do you think of my list.

this would mostly be for storing small bits of 16+char string. possibly a few one time use passwords for various things, and a password for something like an encrypted device (mobile device, laptop, desktop etc..)

not exactly "testing", but i dont think this really needs a whole thread.

what exactly is the export button for. i made a few addresses and clicked it and saved it to my desktop, and it put out a file that just contained what i assume are public keys. is the client still missing private key exporting and importing? its been a while since i have even had the client installed, so i have no idea. and if this isn't private key importing/exporting, will it ever come out? or are the bitcoin devs too busy changing the ui instead of implementing a very useful security feature that should have been around 2 years ago.

i also see a backup wallet feature, but no restore feature.

and the sign feature is pretty much useless as there is no validate feature, so whats the point of making signed messages that no one can easily verify.

and if i were to suggest 2 features it would be block chain backups and offline transactions

i am not angry, i am just confused. but i think what i said above is pretty much common sense for what bitcoin is.

and yes, i am aware of armory, but most users will likely never use it, so the most important features need to be in the mainline client.
5  Bitcoin / Bitcoin Discussion / Re: Michio Kaku: Tweaking Moore's Law and the Computers of the Post-Silicon Era on: April 14, 2012, 05:47:41 AM
A rather shallow analysis. He first asserts (he doesn't explain) how fundamental limits to further miniaturization of silicon devices are based in heat (the chip would melt itself) and leakage (due to quantum principles electrons won't stay localized in such small features - "can't say anymore if an electron is in the chip or outside the chip").

Then he moves on to mention molecular circuitry whereby current flows through a molecule instead of only through metals and silicon - but he never explains why the above two fundamental problems wouldn't apply to molecular circuits. It's not like organic molecules are more thermally stable than metals and silicon, or that they are bigger than patterned silicon features.

What a waste of time.

there is some research that shows that carbon nanotubes do not generate heat in or on the actual tube, but rather the area around it. I do not know how much that would affect the whole thing (there is still the problem of where does the heat go, what would stop it from going to the tube?). and mores law only states that the amount of transistors will double every 18 months. this has little to do with the "speed" of computation of complex problems.

You could likely argue that the current main stream system (x86) is old and inefficient. current mobile processors like the arm architecture in a way prove this. although i have no idea how well they scale up to high frequencies.

but really, we do not know how this will all pan out until they actually start to make some chips that do useful calculations reliably.

I hope you guys get your money back, they are nothing more than crooks for doing that, and I will not be satisfied until justice is properly served to them.

I apologize for any preconceived notions about you guys, you are needed in this market, weather i like it or not, it needs competition, and you guys supply just that.

Its sometimes a pain in the ass to actually give your money to them as well (atm it kinda is a pain in the ass to get bitcoins from fiat as well.). Although you would only have to do it once and a while for all your "services"

has anyone ever thought of the possibility that the coins are just lost. its very likely satoshi will never get them.

mmmmmmm imagine the Ghash's, but there more likely to use it for cracking pgp and truecrypt
Since they will just have a lot of parrallel processing power, and have not discovered any real vulnerability in those protocols, it seems it will be enough for truecrypt and gpg users to double they maximum key size and be done with it. As I understand it, the difficulty to crack them increases exponentially with longer keys.
I use 4096 bits for everything, so I'm fine.
Using larger key sizes won't really do any difference unless your password also has double the entropy. We're slowly reaching a point where humans are having trouble remembering pass phrases with sufficient entropy (we're not there yet though!).

Once you get to that point, you can just hash the part you remember and use the hash as the password. The part you hash would still need to be strong, and it would force the cracker to either, use hashed values, the actual values, or both. We could also go the route of using patterns instead of characters.

The red dots are places where red dots on other shapes "lock". The basic idea is that you would be making a vector object, then use that code as the password. Again these are vector objects, so size does not matter. all that matters is that the correct shapes are connected correctly in the right orders, etc..

Ill say what i always say again, its a good idea to keep your data both secret (keep it away from prying eyes) AND encrypted. sometimes both are not possible, but you should try when you can.

For example, bitcoin, this is almost never possible because by design, you give out your public key.

However, secret documents and messages can be both secret and encrypted. You only give the encrypted data to whoever needs it.
12  Bitcoin / Bitcoin Discussion / Re: The way US government can crack down Silk Road, Tor and Bitcoin on: March 18, 2012, 12:30:29 AM
i love all these armchair revolutionaries talking about how the government can take SR down, "but they can't kill TOR and BTC" bullshit.

they can do whatever the fuck they want.

they can't stop TOR and BTC - but are you going to fuck with that shit when they are threatening you not to?

they said the same shit about file sharing sites - now many of them are shutting down VOLUNTARILY. cuz they are scared.

we got guys under indefinite detention in this country.

so let's stop all this "from my cold dead hands" gayness.

arguing from the constitution is fail - it's worthless.

you are 100% right. The current internet is broken, so we need a new network, set up in such a way that it is better for freedom of speech and such, and not friendly to draconian legislation and control.

Other than that, all you can do is arm yourself with liberty and serve justice to those that need it most. I am a firm believer in fighting fire with fire, as we all know protesting is usually slow and ineffective.

The constitution is just a piece of paper with stuff written on it 224 years, 6 months and 1 day ago. it is only useful (or has power) as long as both parties agree to obey and defend it. The only binding law is the law that gets defended. Everything anyone ever does is nothing more than a bunch of agreements. For example, your money is an agreement to pay debt as a later date. Your bank accounts are nothing more than a running total of amounts of "money" to be moved around to certain people/entities.

yeah? where are you going to stash the guns?

The park, the woods, abandoned houses(not so good idea?), a river, a lake(water tight container in this case). GPS is so cheap today its not even funny, so that would not really be a problem, even if it were not very accurate, as long as you were also given some landmark too, like the 3rd bush from the left from that red house as you come in from the highway, approaching from the north.

If i were selling guns, id dead drop them ahead of time, then when the sale went through, just tell them where the gun is. drugs could work this way as well. Although i can not think of anything similar for people buying stuff.

I concur, violence gets shit/ stuff done.
16  Other / Politics & Society / Re: This is why online businesses should only accept bitcoins on: March 13, 2012, 12:10:14 AM
A decentralized way to exchange fiat for crytocurrency of any kind is fundamentally impossible to do without 100% trust, which does not exist. So we wither need a bunch of local dealers, vending machines, better online exchanges, whatever. but it can not be decentralized in the way that bitcoin is.
17  Bitcoin / Bitcoin Discussion / Re: My tips to secure external bitcoind on: March 10, 2012, 04:59:34 AM
good stuff, except they should have known this before they set the stuff up, hell, i am a nobody when it comes to hosting stuff and web dev, and i knew this. that only leaves 2 possibilities, they run for only profit and don't give a shit, or they are really just very very lazy and don't give a shit.

And you may also want to mention keeping everything locked up.

19  Other / Politics & Society / Re: Kony 2012: Is this ethical, morally just but questionable, or just plain wrong? on: March 09, 2012, 07:22:26 AM
original propaganda

some talk about it (she is from Uganda and has very good stuff to tell)

Kony may not even be in Uganda anymore, and in fact might even be dead already.
in short, if there is oil in Uganda or some other valuable resource, this will create another useless war. I also heard that it is possible that the PRC has been doing stuff in Africa, and the US is trying to keep up. This might lead to a second cold war.

and lastly, do research, do not just take what i say as fact.

It scares me that websites dealing with the amount of money you guys deal with even have the remote consideration of using these types of services (clouds and vps). simply a joke and a very good reveal of the security taken by all these companies.
