bitcoincharts.com/t/trades.csv?symbol=mtgoxUSD&start={UNIX_TIME} is broken?

I can't seem to get it to work properly anymore.

I saw some threads from about a week and a half ago, but I am wondering if anyone has any updated info on this.

If anyone has another method for getting historical mtgox trade data in such a format I would appreciate hearing it also.

Regards,

Johnny

If you need to ask these many questions with the forum full of information repeated over and over then maybe you aren't ready to invest in such a project? I only ordered an SC and since I don't "need" that $1300 anything I make in return is a plus for me. $1300 to me is a few shopping trips at Walmart. I just won't visit as much as I do. Smiley



The reason I am asking so many questions, is because I plan to spend significantly more than $1,300.

Also, just because you are frivolous with your money, does not mean everyone is. There is something to be said for caution, especially in market conditions such as these.

But, thanks for your comments, however useless they were.

Is that 19,000 number accurate or an exaggeration?  source?

Buying in at this point is a risky proposition. Perhaps even across your suggested 12 month period I would likely wait for hardware. The price of BTC is at a record high, and I have been around long enough to know what is likely coming.

EDIT:
- thanks for the link to the forum; didn't realise there was a BFL forum.

- I saw a post with something about 16,000 queue which makes your 19,000 figure look a little more credible: Are all the ASIC chips common for all units, so every BFL product (and the entire queue of pre sales) is waiting on the same chips?

Don't listen to cdog. Bitcointalk is filled with people of 2 different camps: Those who have orders with BFL, and those who think BFL is the devil incarnate. He's obviously of the latter mindset.

There are 19,000 order numbers, but they started at ~1600, and only paid order numbers actually get shipped. It ends up resulting in a lot of false numbers that aren't really orders at all. I myself went thru 7 order numbers before I finally bought my first SC Single (due to wallet problems), so there aren't actually 19,000 people in front of you.

A: I am a BFL customer, so I dont know what you are talking about
B: The false ASIC orders were removed from their system recently. So its 19,000 - 1600 or whatever # of FPGA units they sold is.

My point stands. If you dont mind being out $30k for 18 months and then making a marginal profit, its probably a good gamble.

Thanks for the response.

I am reconsidering the 30K unit, as it seems like getting several 60 GH/s units may be the better way to with the current backlog of BFL orders. The $30K may be too big of a liability for anything > 6 months wait...

Does anyone know if there is a good place to look for people selling their BFL pre-sale queue positions? Also, is there a good way to do this; Do people get updates regarding their position in queue?

I would be happy to pay a premium; almost goes without saying.

Regards,

Johnny

The people who are at the very front of the queue, like myself, will most likely not give up their spot for anything less than an obscene amount.  Many people have asked looking for a June or early July order -good luck - you're better off finding a Cass coin on the sidewalk.

The other issue is BFL and Avalon will not allow changes to shipping address to avoid issues with people's accounts getting hacked.  So even if you bought someones order you would then be delayed by waiting for a second shipment.

Best bet now would be to buy coins and wait for a strategic entry timing (as more ASIC vendors will pop up).

Thanks for the response.

I understand your viewpoint but at the time the ASICs were announced I was skeptical and the market was far more bearish, thus my lack of investment. At this point however, the market is far more bullish, and that's why me and everyone else is here trying to make the safer bet.

I am sure, though, that there are at least a few people in less than optimal financial situations willing to take the smaller profit now than wait and risk the difficulty increase and unknown BFL wait times. A bird in the hand is worth 2 in the bush.

The second shipment is fine, because I would not accept a spot in queue from anyone outside US who is not in Australia or New Zealand or somewhere else close. This means that the total extra shipping time is likely negligible as US to US shipping should be relatively quick.

I think looking for new ASIC vendors is a silly option; The very same problems we have seen with Avalon and BFL and other startups will plague any new startups, but not only that. BFL and Avalon have a first to market advantage which means they have much more capital to throw around due to interested buyers. They also have their R&D data to draw from, which when talking IC fabrication and assembly, is pretty damn valuable. Furthermore, they have actually done fab runs of chips and assembled the devices along with testing them. This process will only be streamlined and specialized from here on out, making BFL and Avalon pretty formidable competitors for any new entrant.

Johnny

Hi All,

Thanks for checking this thread.

I am looking to buy a place in queue which is preferably < 6300 (queue number).

I am willing to buy more than one unit and probably several depending on the price. I am well aware the price will be more than list price on the BFL site - please just PM or post prices.

We would need to work out escrow, shipping and an associated contract for the purchase.

I am happy to pay all _extra_ costs related to shipping from the original buyers location to mine.

Please either PM or post.

Thanks,

Johnny

Why do so many people have advertisement in their signature to order BFL products when there aren't any to order?


It's called marketing; Unfortunately, this type of product is unprecedented and grown from an organic movement. That makes these types of products and their development cycle inherently unpredictable due to inexperience of the entrepreneur's and unknown nature of new technology.

You should be so lucky to order and receive one I think - I know I would feel lucky if I were able to purchase and receive one or many units as soon as possible.

Please don't derail my thread though. I am still very interested in everyone's experience with BFL and ordering / recieving / confirming hash rates of ASIC mining units. 

Thanks,

Johnny

Johnny sorry to be the bearer of bad news, but you are very late to the game. Not only have the BFL products not been released, they have been delayed over 6 months. The chips havent even all yet been made, just a test wafer which hasnt even been fully tested, let alone assembled into a working prototype, let alone manufactured into a product ready to ship - and their customer support is non-existent. IF they are able to get all chips working correctly, IF they are able to build working prototypes and final builds, THEN maybe they will start shipping in a month or two.

BUT if you order now, you have 19,000 orders ahead of you and by the time you get it in September-October the network difficulty will be so high that it will take at least 8-12+ months just to break even on your investment. By 2014 the profit per GH will be low - very low. Its maybe worth it if you dont mind a high risk long term investment - MAYBE.

If you are bullish on BTC, buy BTC with the $30k - because you will start making $ immediately - not 12+ months from now.  

Is that 19,000 number accurate or an exaggeration?  source?

This: http://products.butterflylabs.com/homepage/1500gh-bitcoin-miner.html

Does anyone know what the deal is with purchasing one? I have tried to contact BFL regarding purchasing one, but as of today have not yet heard back.

- I would like to know if they ship globally, and how import expedition is handled and by who.

- I would also like to know what the turn around time is, assuming I purchased today.

- Also, has anyone confirmed the hash rate at 1,500 GH/s ?


Does anyone know a way to call and speak with anyone at BFL? Or at least a surefire way to get some sort of response? I am happy to spend the $30,000 but would like some communication with BFL before doing so.

LinuxCoin works in under 2gb. I use 4gb w/ 2gb persistence file for when I want persistence. It also works great in transient mode for when i don't want to leave a trail.
No idea if others agree - but I'd certainly not use a distro that isn't generic.
The problem with using ANY distro targeted at bitcoin is that something could get in there to take advantage of that.
It certainly creates the possibility of a very LARGE financial gain for anyone unethical enough to attempt such a nefarious act.

My mining rig uses Xubuntu 11.04 and I've documented a list of commands to create it/update it to running cgminer - and the reason I specifically did this is so that it starts with a generic distro (built from the Live CD) and thus I am not a suspect in possibly producing something that could have a backdoor or wallet capture issue ... and no one needs to trust me to use it - they only need trust any software I've said needs installing.

In case anyone is thinking it: the reverse is not worse.
i.e. being worried about a backdoor or wallet capture in the generic distro: since if that is there, any bitcoin targeted distro made from it will also have the same problem (no one building a bitcoin distro is going to search all the software installed on it and guarantee to find issues and remove them)
If anyone finds such it would certainly be removed upstream as soon as they were told about it.

Unencrypted wallet.dat files are the bane of bitcoin (in my opinion), and thus any decision I make about a software distro on a machine that may contain one is going to not choose a distro with bitcoin in it's design target - only as add on software (though for me it won't ever include windows either)

LinuxCoin doesn't have a wallet stealer inside Cheesy There have been 10000's of downloads and no ones complained about their wallet being stolen from a linuxcoin install yet. Also LinuxCoin is like  Xubuntu on roids Cheesy It has added security features you just wouldn't find in a generic OS.

I have had a quick look at the page for Linux Coin, and I may just be missing it, but can't see the added security features. Could you point me in the right direction or elaborate on them for me?

Grsecurity / PaX hardened kernel giving linuxcoin Role-Based Access Control.
Tor / privoxy preinstalled
sandboxed applications ie; apache  (Coming with next update) If an attacker gains access to your system via the http server which is running for the munin bits and bobs It's jailed.
Optional wallet encryption (Next update depreciates the scripts for the in house wallet encryption.)
bitcoin client has been compiled with hardening cflags.
The system RAM is overwritten when LinuxCoin is being shutdown or when the boot medium is physically removed. Handy if your using linuxcoin not on your personal computer. coming with next update.

More features to be announced. Put this all together with an encrypted home-rw snapshot and you've got a very secure system to store your coins. I realize that the trust has gone with a lot of people but I'm not in it for a profit and if I was going to include a wallet stealer I would of done it when bitcoins were worth around the £20 mark lol


Sounds like a nice set of features and features to come.

If I wasn't already happy with my own generic setup I may have considered this distro.

Keep up the good work, we need more security concious people developing wares for Bitcoin.

Due to my general borderline paranoid attitude in regards to any IT security issue, I would have to side with Kano here.

Although, I am making no judgement on the authenticity of Linux Coin and do not doubt the honest and ethical nature of the creators. I really applaud them for making Linux accessible as it can be a bit of a struggle for the inexperienced.

I feel like my solution is a fairly good effort and I would love to hear about other peoples solutions as well as the more documentation we have on securing Bitcoin wallets the better.

16  Bitcoin / Development & Technical Discussion / Re: Linux VM Secure Wallet on: August 12, 2011, 02:59:07 AM
So I am now quite happy with the VM and OS installation.

I had installed the Bitcoin client last night and left it to run all night to download block chain.

When I woke up it had crashed, or, at least was not running.

When I attempted to restart both the GUI and console versions I got the following error:

EXCEPTION: NSt8ios_base7failureE ReadCompactSize():size too large bitcoin in AppInit()

Searches on this error did not reveal much. I was wondering if anyone had any insight on the possible causes of this exception?

The only changes I had made before I began the block download, was to "mkdir ~/.bitcoin" and "echo 'keypool=300' > ~/.bitcoin/bitcoin.conf"

I will be definitely backing up my wallet file separately from the VM once this secure wallet system actually holds Bitcoins, but regardless, would really feel much more confident if I could figure out these types of bugs beforehand.

Thanks,

Johnny

I have some experience with RH distros but am far more comfertable on debian and when it comes to finances, I would rather be in comfertable territory.

Hmmmm, I have no experience with Linux Coin. First question would be is it lightweight enough and how much stuff do I need to remove?

I have had another attempt at my build today. Starting off with base Ubuntu Server install and am running this install right now:

aptitude install --without-recommends xubuntu-desktop

This approach looks like it will net me alot more space to play with on my 3.75GB virtual drive.

During the server install I also manually partitioned up the virtual drive leaving only 200MB boot, 3.7GB root(encrypted LVM) and no swap. I figure seeing as it is a virtual machine I can just increase RAM if ever I have swap issues and it should run fairly light anyway.

I will report back shortly on how the GUI install went.

JG

Well I have to say this latest attempt has the been the best yet.

I started with a plain Ubuntu Server install on a 3.75GB virtual disk.

After that was done I just ran: aptitude install --without-recommends xubuntu-desktop

After Xubuntu Desktop install and before the Bitcoin install and subsequent block chain download I have 2GB free space.

I think we have a winner Smiley

This idea definitely has value and could work with some attacks.

I would categorise Bitcoin enthusiasts and anyone coming after their loot as having a higher than average level of technical sophistication though, and if it were me coming after a wallet file, I would probably be looking for flags like -wallet as well as default file locations.

In short, I think wallet encryption should be the highest priority security measure for any wallet.

Just my 2 cents.

I didn't want to get too obscure with my distro choice.

Ubuntu is a nice popular and compliant platform and Xubuntu is just a little lighter.

I agree my implementation/installation could have been done better. I am actually considering redoing it with a minimal iso and manually installing only required components.

Could anyone suggest a better distro or implementation?

Thanks,
