I agree for the most part: yes I think bitcoins are overvalued, they will go back down in price, most of the recent increase is speculation, etc.  However, I think you fail to take into account the rabbid 'fanboy' nature of many people involved in bitcoin.  They are so zealous about seeing bitcoin succeed, they often do irrational things to try to 'keep bitcoin alive', eg. mining at a loss, holding bitcoins to artificially reduce supply, buying bitcoins to keep the price afloat, accepting bitcoins for items at less than market value, etc.  So while I think the price will come down perhaps significantly, I think there is a core of fanatics that will keep bitcoin afloat to some degree despite any rational reason for doing so as compared to stocks, etc. where people are merely in it to make money.

3 x 5830 = $320
Motherboard = $100
Power Supply = $50
Processor = $30

Total = $500

hard drive? memory?

USB = $1

Cheap Memory = $10.

You people are ridiculous.
case? operating system? fans? keyboard? mouse? printer? scanner?  fax machine?  56k modem?!?
3  Bitcoin / Mining software (miners) / Re: [MINER] Phoenix - New efficient, fast, modular miner **BFI_INT support!** on: June 02, 2011, 03:27:00 AM
There seems to be a memory leak somewhere (maybe not technically a 'memory leak' since you are using Python but), phoenix uses several hundred megabytes of ram after several days of running.  My guess is a failure to prune some sort of list of completed shares / console output / something.  I would simply quit and restart, but I've run into the previously mentioned bug where my normally stable system would completely freeze upon exiting phoenix.  This one I can't seem to reliably reproduce, it happens sometimes upon exiting but most of the time it's fine.

They are wrong about the threads operating on the same data. A naive reader skimming over the code may think most of the data is the same, but the 32-bit nonce is unique for each thread, which leads to different SHA-256 intermediate hash values (A-H) being manipulated by each thread.

Re: enterprise prices - it is truly market segmentation, whether you want to believe it or not. The 2 largest and public disk reliability studies ever performed were made by Google and CMU. They reveal interesting findings. In particular, contrary to what you think, the CMU one reported no statistical differences between the failure rate of SCSI vs SATA drives on a population of 100k+ drives:
* Failure Trends in a Large Disk Drive Population - Google
* Disk failures in the real world: What does an MTTF of 1,000,000 hours mean to you? - CMU
Which makes sense when you think about it. Commodity drives are produced in such a high volume that it is in the manufacturer's interest to make them as reliable as possible, because a small improvement in reliability drastically reduces the number of warranty claims.

This is just some food for thoughts... You should trust more of the people here. The Bitcoin community is full of smart folks. Open source has produced some of the highest-quality software in the world: Linux, Apache, etc. A miner is also just a few hundreds lines of code. It is not a complex, hard-to-optimize software beast that you may imagine.

What is your opinion on this?:

Theoretically possible or not?

Latest drivers on Windows, clocking in at 800 mhz core / 300 mhz memory, I am getting about 295 Mh/s using phoenix 1.4.  This is the Saphire 5850.

One sold to Syke (thanks), one still left.  Price is 28 bitcoins.
9  Economy / Marketplace / Re: [Selling] World of Warcraft 60 Day Pre-Paid Game Cards for 28 BTC each on: March 29, 2011, 07:45:54 PM
Lowered the price again.  Pretty good deal given the current BTC exchange rate and the fact that these retail for 29.99 USD.
10  Economy / Marketplace / Re: World of Warcraft 60 Day Pre-Paid Game Cards for 30 BTC each on: March 27, 2011, 10:51:24 PM
Lowered the price on these.  Both are still available.

These are unused (obviously) WoW 60 day game cards.  I have 2 available.  Will ship these to the US via regular mail, or I can just scratch off and email/pm you the code, if you so desire.
12  Economy / Marketplace / C/C++ Tutoring Available for BitCoins on: March 18, 2011, 11:19:44 AM
Need help with a programming assignment, or need some insight into some unfamiliar or poorly understood C or C++ code?  I can help you.

I have a BS in Computer Science from a major US university.  Although I have experience in a variety of languages, I would only really consider myself an 'expert' in C/C++ (that is, if anyone is can really be called a 'C++ expert', hah Tongue).  I can help you with basic Java/PHP/SQL/whatever issues, but I don't use them on a daily basis so I may be unfamiliar with some finer points of the language.  Of course, many computer science issues transcend programming language, so I can explain concepts to you regardless of the language.

I enjoy helping people learn, and I would like to like to earn a few bitcoins in the process.  I'm not trying to cash in per se, so you can pay me what you think my help is worth.

Demonoid invites are gone, thanks guys  Smiley.  3 TvTorrents invites are still available.

Can you provide more info on TvTorrents?

As the name suggests it's a private torrent site for tv shows  Wink.  It has archived basically every episode of every TV show I can think of, and releases new episodes usually a couple hours after they air live, usually both in SD and HD formats.  What's nice is that you can mark what shows you watch, and then it will provide a customized RSS feed of new torrents for your shows' episodes, then using uTorrent or whatever client you have that supports RSS torrent feeds, you can have them downloaded automatically.  Being a private tracker, bandwidth is always plentiful, but of course you can't just free leech either.

i'd take a demonoid invite,
first the invite or first the money?
Well in the interest of establishing a good reputation, I'll send the invite first.  Check your PM's.

Just trying to get started off with this whole BitCoin phenomenon.  I have 3 TvTorrents and 2 Demonoid invites available.  Also looking for a SafeOrScam referral code, pm me if you have one.  Thanks.
