I'm tired of trying to cater to the nutbag leanings that have absolutely no basis in reality in terms of time frames, business practices, or technical development.

The "Ignore user" feature is the best thing added to this forum in a long time. It makes even threads like these worth reading, since many - many - posts filled with complete drivel are silenced.

142  Bitcoin / Hardware / Re: ZTEX USB-FPGA Module 1.15x: 190 MH/s FPGA Board now on stock on: December 06, 2011, 04:54:31 PM
Thanks and agreed, maybe a bit much to call ztex a scammer. I apologize to the community for my wrongly choosen words.
I only wish ztex to take his part of responsability for this problem.

I consider myself to be way above average when it comes to electronics, but no where near the level of ztex and enigma. I could've done the same thing as you did in your situation - I actually did hook up another small consumer electronics device where the manufacturer psu had died upon me to a psu I found laying around just a few weeks ago after having just verified polarity and rated output voltage*.

It's possible I thus could've fried one of these boards as well, being that careless, and not immediately considering the difference between switching and transformer (which is where my mostly DC/digital knowledge of electronics ends).

However, there's no way I would blame ztex. I'm sorry, but consumer electronics are never protected against over voltage. There's no reason to assume these would be either, thus there is truly no responsibility on his part.

I do thank you for bringing up the subject, which has led to additional information and cautions now being available for those (which might include me) that buy boards from ztex or anyone else in the future.


*) edit: I also measured the voltage with my non-cheap multimeter, although it does not show max/min as most don't

As a side note, I don't think bitcoin ever really reached $32

I bought at bitmarket.eu on the evening (CET) of 9th of June, which should be very near the all time high, at 21.5€/BTC which according to the exchange rates at the time would be $31.23.

Yes, I make sure to tell everyone I introduce to Bitcoin that I bought at the height of a bubble. It helps in avoiding coming off as someone who peddles a ponzi scam.

Who makes Bitcoin liquid, and more easily exchange able into other currencies, if not traders?

Wall Street ponzi scheme HFT trading mumbo jumbo with no basis in actual reality. Bitcoin needs nothing more than miners wanting to recoup the cost of verifying transactions for people to be able to acquire the necessary currency for economic transactions.

A quick read through of the Speculation part of this forum is all that's needed to understand just how sad things can get. "My charts show that we're headed upwards. BUY BUY BUY".

The only way to profit from that is if someone else loses. No net gain for Bitcoin.
145  Bitcoin / Bitcoin Discussion / Re: At what pricepoint is bitcoin dead? on: October 10, 2011, 11:13:26 PM
This was kind of my point... it wasn't about being a "ponzi scheme trader" or whatever the guy with 8 posts was saying..

Oh I think I'm up to nine posts, or so.

I don't consider the trading of BTC to add anything to Bitcoin's success. A trader can only profit if another loses, and if we're trying to build a new kind of economic system where's the net gain in that?

You cant just ignore the price it cost to create a bitcoin

Correct. And since GPU miners will be replaced by FPGA/sASIC/ASIC the cost of producing bitcoins will continue to fall, even if difficulty stays where it's at.

146  Bitcoin / Bitcoin Discussion / Re: Is Silk Road the best setup to handle commerce?? on: October 10, 2011, 08:29:27 PM
The reason it looks like it's the only successful model is because, for the time being, shopping online for legal items that are otherwise high value and easy to ship works just fine with credit cards.

Agreed. Bitcoin needs to focus on its strengths, and that isn't in replicating business models that are successful in non-Bitcoin systems. There are a few low hanging fruits that should get more enough attention:

1) Replace Western Union. Seriously. Their fees are enormous, yet it's usually the only option for resellers of grey area items (modchips for games consoles etc). That these companies haven't already switched to Bitcoin surprises me a lot, they transfer quite a lot of money.

2) Meds. While this exists on Silk Road, there are customers who have no problems buying medication that happens to be prescription only in their country but otc in other countries. It seems "more legal", but they wouldn't want to be mixed up with SR. I think I've seen someone on the forum doing this.

3) VPN services. I'm happy to see that some are now accepting Bitcoin payments, but there are many more that could (should).

(Not that I'm advocating doing anything of the above, of course, if it's illegal in your chosen country of residence)

I don't mine, and never have. I don't consider "mining" to be of interest until we're at the level of ASIC/sASIC/FPGA. At that point (and we're very near) I'm going to put together a wall-socket mining system drawing almost no power and using the Wifi everyone has already.

It's not meant to make the owner money, it's meant to make sure that Bitcoin works and can be trusted. It's your own cheap little way of supporting a better currency and financial system, and there are a lot of people who'd buy and install one just to show their support.

Hopefully none of them will join pools, or ever sell any coins that might be "mined":


148  Bitcoin / Bitcoin Discussion / Re: At what pricepoint is bitcoin dead? on: October 09, 2011, 08:58:19 PM
I can't see making any money on the trading either really.

Great. I'm all for a rapid fall in the BTC/$ exchange rate followed by an immensely stable price point if so only to drive away all the traders.

If we want to replace the way the economy works I see no point in creating a second Wall Street. The worst part of Wall Street even, the ponzi schemers.
149  Bitcoin / Project Development / Re: UK exchange: Intersango (formerly Britcoin) on: October 08, 2011, 06:48:39 PM
I can't vouch for BitMarket.eu but relatively speaking I have not hear of them lying, stealing or being hacked or any combination thereof so that puts them at the head of the pack for most prominent bitcoin exchanges

I've used them for all my BTC purchases except the very first. The difference between them and exchanges are that they're only brokering1 the trades - the buyer pays directly to the seller. They do escrow though, which means they could in theory do something funny once the BTC are released by the seller into your account. So far, as you state, I've heard of no such issues. I also like that there are no day traders, too small volume and there's a general price premium2 above the popular exchanges.

I alway withdraw immediately though, there's simply no point in not doing it. I think it's good advice.

(There's also some basic persona verification being done when registering)

12) That's also why I wouldn't consider them to be a "competitor" to you.

the number 1 problem is what do you do with the waste.

What we call "waste" from the reactors we mostly use is in reality 95% fuel. A modern reactor would continue to burn it until all is spent, and what would be left could easily be stored onsite (a few tonnes over the life time of the reactor) and would only be radioactive for hundreds of years instead of thousands.

I thought that there was one case of an overexposed plant employee who died after trying to help put out the coolant pool fire.  I might be wrong, or he simply died of something other than radiation exposure.

The latter, I'm quite positive.

151  Bitcoin / Bitcoin Discussion / Re: Paypal Strikes Again, This is an Opportunity for BTC to Prove its Value on: October 07, 2011, 11:38:55 PM
Do you really think after Chernobyl and Fukushima ANY other source could have spewed more radiation into the environment?

Yes, it's absolutely correct. You also need to separate different types of radiation and the half life. Radioactive particles released from coal plants are alpha emitters with long half lives. While Chernobyl was an excellent example of how you can purposely cause a non-civilian type of plant to melt down and create a radioactive cloud (graphite moderator burning) Fukushima is a completely different matter and didn't release anywhere near the same amount of particles.

(None of the above is what anyone "thinks" btw. The physics is simple)

Irrational fear of radioactivity is bad for you.

People died from both the Chernobyl event and the Fukushima event due to the concentrations of lethal exposure

Just to be clear, there are no deaths from radioactive exposure with regards to the Fukushima event.

152  Economy / Gambling / Re: BTCLot.com - New way to gamble bitcoins (NOW WITH POKER) on: October 07, 2011, 09:16:55 PM
I've worked really hard on this website. Does anyone have a sugestion of what should be upgraded/improved ?

Well. After having viewed the video and read the FAQ I'm still not sure what it is about. But then, I don't usually go about making bets (I can only assume there's nothing there until I would create on myself with others?)

Also, nothing indicates that there would be poker.

(I think there are more gambling sites available than the current BTC userbase can handle)

We would want the conference to have at least 200 people attend and there just doesn't seem to be that level of interest.

While your goal is completely understandable, that's a very high number of paying (I assume) attendees for an unproven conference. Especially if most of them need to/will be traveling in and not local.

I go to a lot of conferences (both as attendee and as speaker), and have been to everything from well published recurring ones where the only attendees ended up being the speakers (!) to those where there are thousands of of local and hundreds of traveling participants. Many conferences end up doing last minute "bring # of your colleagues / classmates for free!" deals.

Here's hoping you will succeed Smiley From the outside (my schedule simply hasn't got room for me to join) it looks as if you're doing a great job.





155  Bitcoin / Bitcoin Discussion / Re: Are you struggling for passwords for wallet encryption ? on: September 23, 2011, 09:38:12 PM
if you use 9 digit purely random password (containing upper, lower, number & punctuation), always generate them randomly, never re-use them (password re-use kills any security you have), and never store a backup copy online then nothing is safer and it is impossible to brute force with current hardware. I doubt you do that though.

I'll just keep repeating "LastPass", since it's by far the easiest way to get non-security trained consumers to use proper passwords. Always generated randomly, contains the full charset incl. numbers and special characters, never re-used and with no plaintext backups stored neither locally nor online.

Doubt away.

Keep it in your own hands.

LastPass neither have nor can they retrieve your passwords. They're "in your hands".

That a 62^50 db is impossible to store? It is... at least so far

It's many orders of magnitude larger than the number of atoms in the universe. You fail at simple math.


159  Other / Meta / Re: Info about the recent attack on: September 20, 2011, 08:10:21 PM
I merely mean that if a single hashing algorithm was used in the planet, the RT for it would be by now enough to consider such algorithm more than broke.

We understand what you mean. We're just proving you wrong.

Sadly you don't know enough math to understand it.
160  Other / Meta / Re: Info about the recent attack on: September 20, 2011, 04:28:17 PM
imagine if single hashing algorithm is used web-wide, this would be a leverage to a potential attacker, a single RT would be enough for all unsalted hashes and by now probably even 50 chars long pwds would be there.

I lol'd.

Assuming just lower case + upper case + numbers, no special chars, that's 62^50. Converting to a more familiar base 2 representation it's equivalent to 2^298. Tell me, in which universe where you planning on storing that rainbow table, and for how many heat-death-of-the-universe-eons were you planning on creating it?

When you fail at math, you fail at crypto. Hard.

(edit: Number of atoms in the visible universe: 2^266)
