It's the free market at work, baby.

Free market means nobody has moral standards, then?

Re: Accessing MT Gox API from Java

This works for me:
Code:
        final URL url = new URL("https://mtgox.com/code/getFunds.php");
        final HttpsURLConnection urlConn = (HttpsURLConnection) url.openConnection();
        urlConn.setDoInput(true);
        urlConn.setDoOutput(true);
        urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        urlConn.setRequestMethod("POST");
        final DataOutputStream printout = new DataOutputStream(urlConn.getOutputStream());
        final String content = "name=" + URLEncoder.encode(USERNAME, "UTF-8") + "&pass=" + URLEncoder.encode(PASSWORD, "UTF-8");
        printout.writeBytes(content);
        printout.flush();
        printout.close();

Did you forget to URLEncode your username and password? Or is the typo where you set the "Content-Type" to
Code:
"application/x-www- form-urlencoded"
really there?

Re: What would it take for you to lose faith in Bitcoin?

If someone found out that the system was flawed or if a successor got more traction than bitcoin. But I don't think either of these is likely. (There remains a risk, but: no risk, no fun.  Grin)


Why don't you think the latter is likely? All it would take is a more concerted branding effort and a more user-friendly operation and it would wipe this shit out of the water.

Got no real reason for my thinking here.... Ok, I got to admit it is more that I believe it is not likely. (But thats all right, as the question was about "faith", right?)

Re: Idea: Make it possible to import public keys

Thanks for your answers!

@Forp: Gave me a way to achieve what I wanted much easier than what I intended to do. I am sure I will give your java scripts a try soon! Thanks!

@JoelKatz: Yep, I can see that this is the bigger picture and export/import of transactions makes a lot of sense. With this approach one can even withdraw money from the secured wallet without ever exposing any private key to the internet. Very cool, thanks!

Idea: Make it possible to import public keys
by
holgero
on 27/06/2011, 20:16:20 UTC
Hi,

I was reading through the guides how to set aside some of your bitcoins in a secured wallet. (Works like this: Create a new wallet on a second PC without internet access, create some addresses in it and store the wallet somewhere safe. Later on just send your money to the addresses in that wallet from your day to day wallet to tuck them away. Check with the blockexplorer if your funds arrived at the secured wallet. Never connect your secured wallet with the internet...)

But I found it a bit inconvenient to have to use the blockexplorer to verify whether your funds arrived safely in your secured wallet. So here is the idea:
If I could import the address from the secured wallet into my everyday wallet (but not the private keys!), I could let the bitcoin client take care of monitoring the transactions that concern my secured wallet. This way I could see (an estimate of) the balance in my secured wallet without compromising its security.

I could try coding this, but would you say it might be worth the effort (i.e. would it have a chance to be pulled)?

BTW: A side effect is that this functionality could be used to monitor the balance on arbitrary addresses conveniently with the client, but you can do this currently with the blockexplorer anyway.

What I don't understand is, why do they keep handing out deadlines just to ditch them minutes later? You want to keep the maximum amount of users annoyed, tied to their screen and constantly refreshing your site and this forum?

I believe MtGox hates us.

Moral of the story: length means nothing if your password is still easy to type
...

Uhm, then why are all cracked passwords in the list at most 12 characters long?

cpu mining with 800 khash/sec

Your CPU must suck pretty bad... ouch.

My ancient Pentium M gets 450 Khash/s.

/proc/cpuinfo says it is this thingy:
vendor_id       : GenuineIntel
cpu family      : 15
model           : 2
model name      : Intel(R) Pentium(R) 4 CPU 3.00GHz
stepping        : 9
cpu MHz         : 2992.479


Should it do better?

Re: 7 simple rules to mitigate most threats related to passwords
by
holgero
on 22/06/2011, 18:44:36 UTC
One way to construct a somewhat easily remembered long password is to think of a song, poem or somesuch, which you could remember in your sleep, and then apply some algorithm on the words.

As an example, pick the first three letters of each word from the first line of Paranoid:

Finished with my woman 'cause she couldn't help me with my mind

Then pick some characters to delimit the letters and maybe start or end the password. Make up some rule by which you make some of letters uppercase. For example:

3Fin.wIt.my.Wom.'Ca.she.Cou.hEl.me.Wit.mY.min%

That's 46 characters fairly easily remembered. Half of that would be enough, and in fact 3 letters may be a bit much since I ended up with a couple of dictionary words in there.

(You want the brute-force search space be large: use 1 or more characters from each group: uppercase, lowercase, numbers, symbols.)

Here is a much simpler way to create easy to remember (not only somewhat easily remembered) and secure passwords: Use a complete sentence as your password! If it has more than four words, it is secure enough, and if you make it a bit obscure, nobody can guess it. So instead of
3Fin.wIt.my.Wom.'Ca.she.Cou.hEl.me.Wit.mY.min%
just use
Finished with your wife, although she helped my cat.

And BTW, forget about these special characters and such. The blanks that separate the words suffice. Special characters only make your password more complex and harder to remember. If you are concerned about the security, just choose a sentence that is a word longer.

Why? Because nothing beats length! (an increase in length adds to the exponent of the complexity, one more special character only adds to the mantissa).

In other words: Just make words the atoms of your "password" and you win twofold:
1. It easier to recall a (near)-sensible sentence than a single word (or the trace your cat left when it walked over your keyboard).
2. It is much more secure, because it is harder to crack (both by a dictionary attack and by simple brute force).

Here is the downside: It will take you longer to enter your password...

Hi,

if I understand what's on the wiki correctly, it is not possible to use an ATI "Radeon HD 3650" card for mining, right?

Best regards,
