Latest HashVoodoo Release is up at https://github.com/pmumby/hashvoodoo-fpga-bitcoin-miner/downloads

This one uses dynamic clocking (so far to my knowledge only officially supported in MPBM, waiting for word from Kano if he is working on support for cgminer).

I have been looking forward to this, Thank you Glasswalker, I've always liked your dedication to a stable bitstream.
Downloaded it, will take a look over it, but give it a while before installing to it has it's full support.
I've always used Cgminer, it's what I'm use to. Would like to give a bit of time, but hopefully cgminer will support your protocol soon.

@Lethos  Thanks for the advice. After modified some parameter it working fine now!

Based on the default setting of CM1 it gave 760 to 763Mh/s(avg) with bfgminer. Should it be enhanced after tweak the DIP switches or updating the Controller FPGA firmware and array FPGAs firmware? How could I know the version of my CM1 board's currently firmware for determine the necessity of updating?

Test it for stability first, sounds like Enterpoint (Yohan) is starting to putting fully working bitstreams into them for you.
Most of us posting here, did not get them in this state so we well use to having to update the bitstream firmware ourselves.

If it ends up being stable ask about the mak 200+ bitsteam or hashvoodoo if it is not stable.

Depends on how elaborate you are prepared to go:

For home installations of really expensive items that aren't on show I'm always a fan of the hidden room.
These are usually easy as hell to pull off in basements. Since the floor size is not always the same size as what is above it in old houses.

Half the room off with plasterboard and make a small door shaped hole in it's place. So you have a hidden and open portion of the space.
Place a really heavy bookcase or similar in front of said hole. I'd recommend, removing any "feet" on the bookcase and replace it with marble sized ball bearings to allow it to slide and move around abit.

Fit a A/C unit, big box freezer etc, anything old and clunky that makes a decent amount of noise in the open space, nearby to disguise the sound of the computer in the hidden space. That A/C unit could even help with all that extra heat.

Put a ton of stuff in the open space and make sure this fake wall is decorated, so it's fake-ness is not too easily noticed.

In the advent it is found, I do recommend bolting and chaining it to the floor, so at the least removing it from it's hidden room is difficult and time consuming.

... I could go on...

I've owned a server, vps, shared hosting of some sorts for around 10 years, those have a nice big target on them, no virus' but do get hack attempts all the time. They were all Linux machines very public, since they are servers and host a few relatively popular websites.
Most hacking attempts are pretty basic, so it's easy to prevent with a properly setup firewall.

If you want to go towards server like protection against hacking attempts, that is what you need to look into how to setup your firewall. One method, limiting outside access by IP address to specific ports, anyone else, gets a denied instantly. Figure out what might need to access you from the outside, make note of it's IP address and put that on a white list. Don't add more than you need to.

It's a bad idea to use best-practices for protecting a server to protect a client-system. It's a completely different usage profile at a client and thus a different attack vector. Simple example: A server would never connect to blockchain.info, because it's a server, in best case even without gui or browser. Without a browser there's no risk of getting malware through (for example) an xss-attack on blockchain.info. Nevertheless at the client, this risk is very real.

I know it's different, clearly you didn't read or understand what I said, or read more into it than what I said.
I merely gave advice on configuring his firewall, that is it. None of the stuff you mentioned.

Slightly off topic, but is there an explanation of the new glbse color scheme anywhere?


Stephen did a decent explanation, with a small correction by myself on the black market afterwards.

I would store no more than the number of bitcoins I was willing to lose in that setup. Mainly because you are utterly relying on a third party (blockchain.info), but also because of what flipperfish said.

Ugh.. this is so frustrating. How am I going to lose my coins if blockchain.info won't hold more than what I need for my spending money. And how can a bug get exploited if I'm not going to be actively using my browser.


One more time: I'm going to use my setup as follows. When I want to fund my savings wallet I'm going to reboot to my ubuntu stick, open electrum or multibit(haven't decided yet) open either an exchange page or blockchain.info and transfer the money to my thin client's wallet. After I do this I'm going to close and reboot. If I need to spend my savings money I'm going to reboot to my ubuntu stick, open electrum and open blochchain.info and fund one of my spending addresses. I wont do anything else with my USB stick.

Where exactly is the risk in doing this and how big is it? Is linux really this unsafe that I can't even do the above without risking getting hacked? Is there really no other option but an air gap?! I mean this starting to be too much..

Put it this way, there is nearly always the potential for you to be hacked or get a virus, but you have to under the % chance of this happening and put it in context, just because there is a 0.0001% chance doesn't mean it's going to happen (numbers maybe made up but they wouldn't be far off for any tech savy user).

I've been on the web for over 24 years. Sure my computer has caught a virus or two, but my personal computer was never purposefully attacked or hacked into. Most of the virus' I got was when I was a child or I let someone else on the computer and they did something stupid and it got compromised because they downloaded something they shouldn't of done and yes all of these were windows machines.
Btw the few linux based PC's I've had and never to my knowledge had either a virus or been hacked into, I use the same level of protection on these as my servers.

I've owned a server, vps, shared hosting of some sorts for around 10 years, those have a nice big target on them, no virus' but do get hack attempts all the time. They were all Linux machines very public, since they are servers and host a few relatively popular websites.

If you want to go towards server like protection against hacking attempts, that is what you need to look into how to setup your firewall. One method, limiting outside access by IP address to specific ports, anyone else, gets a denied instantly. Figure out what might need to access you from the outside, make note of it's IP address and put that on a white list. Don't add more than you need to.

So if blockexplorer is the only site you go to, make it so that port will only be open for that IP address of that site.
Same applies for electrum and it's blockchain servers and the ports it uses.

Linux really does not need the same sort of anti-virus protect as windows, so as long as you have something, that is usually enough.

but what court has said that alberto has scammed funds? nefario's word and the opinion of this community is not legally binding.

Meni, was actually the one to revealed he was the scammer, Meni then asked Nefario to help fix a situation that Alberto would not.

Not quiet sure what warrants it to be considered a blue market asset, but I'm sure someone will be interested in it.
I'm not seeing the big deal, am I missing something?

Nefario usually acts according to his emotion but the brain. He forget that he should only hand this to the police but not push those materials  publicly.

There are another accuse against Nefario. someone is accusing Nefario scammed 8BTC here:  https://bitcointalk.org/index.php?topic=110504.0.


Not really the same thing, if you actually read up on the situation.
311  Economy / Securities / Re: [GLBSE] Violating its TOS and Possible Laws depending on country of Origin on: September 21, 2012, 11:24:57 AM
Are we talking about the scammer who agreed when providing his ID that it would be made public if he scammed/defaulted/(de)frauded?

-MarkM-


So where did Alberto agree to this?
312  Economy / Securities / Re: [GLBSE] Violating its TOS and Possible Laws depending on country of Origin on: September 21, 2012, 10:51:39 AM
The TOS probably does need to be clarified a bit better of the element surrounding how the niceties of the TOS don't apply to your account  info/data we have about you if you are suspect / proven of fraud.

Quote
9. The Exchange reserves the right to suspend trading of any asset, or suspend access to an asset creator's account, for failure of an asset creator to provide requested information, or in the event of suspected fraud.

I was not surprised Nefario shared the info/data I admit, after all, a lot of fraud has happened by those misusing his trading site. It's understandable he would be annoyed at them, as it damages his (and the companies) reputation as well.
However I am surprised his TOS didn't mention he could get away with doing that, when suspected or prove of fraud. So yes, [9.] probably should be expanded a bit to cover himself, if he's going to keep doing this.

I'm not much for legal jargon, so meh, scammers have it coming for them really.

Guess the only thing I was hoping to hear is my parole office knows all what I'm doing in this new business, and is fine with the business or something to that extent, with some proof we could believe. Fact is regardless of the story, he does still have rules he is suppose to be abiding by, right? With how he operating a business right now, doing pre-orders on a large scale for products would count as going against those.

I could go into, not all of his story adds up, I imagine since he left some important details out, but that has already been discussed.

I am admit I've spoken out against BFL a few times, Mostly on the aspect of poor factual errors and shipping times, promises broken etc. But they still delivered in large amounts eventually so they weren't all bad.
I didn't suspect it as a scam, maybe a poorly run company as any could be as first getting into the business it is understandable they wouldn't get it right first time round.

This story has not made feel any better about BFL as a company.

Yeah, that didn't add up to me either. I was always under the impression bitstreams can't effect it's "power" or "voltage", nor would it change automatically even if you pushed it hard via overclocking. The worst that happens is invalids or errors in the output.
Well, the FGG484 package that Enterpoint are using is apparently much worse at dissapating heat compared to the CSG484 package that Ztex's boards use, but...

Pretty sure the CM1 uses a bigger fan and better heatsinks though...

@Luke-Jr @Lethos

Finally, after install some dependencies libraries I make bfgminer working on one of my rig (although still need to figure out how to enable GPU mining with bfgminer).
Code:
 ECM 0:                | 379.8/379.8/397.8Mh/s | A:124 R:0 HW:0 U: 5.56/m
 ECM 1:                | 380.5/378.0/349.7Mh/s | A:109 R:0 HW:0 U: 4.88/m
 BFL 0:  51.2C         | 862.1/856.5/930.3Mh/s | A:290 R:0 HW:0 U:13.00/m

However, on the other rig with bfgminer I got:
Code:
All devices disabled, cannot mine!

@kano
Thanks! Will try that.

Assuming you are pointing at the right usbports...

First do a power cycle, and then reconnect stuff and use the modprobe command, try again, did that help?
If not then try reflashing the board. Try again after doing the above.

Although this may be cause for concern to some, the fact is that we're a robust company with 22 employees.  One of them has a colorful background in offshore libertarianism.  If I thought there was even the possibility of something unsavory going on within BFL, you can rest assured I would a) not be part of it and b) would let everyone know it.


That is worrying.

Thanks for your help again.

1)
If you want it to be secure, probably a not good idea not to use this system running just a usb to go to websites that you don't trust 100%.
It's holding your backup/savings wallet, if you want it for dual purposes, use another usb or HD that matters less if it gets comprises. Saying that most such sites infect windows based machines and have no effect on linux ones. That is what the anti-virus is there for, incase you do something stupid, since that is how most virii get on peoples computers.

Yeah I only meant for sites like blockchain.info so I can easily fund my day to day wallet.

No problem.
If that is something you feel must be done while on this system, you should be fine. I can't see why but okay.

Interesting:
Quote
Some bitstreams such as some current “220” bitstreams can use excessive power and hence generate heat that is impossible to extract from the FPGA packaging. This may damage FPGAs and our warranties will not support boards damaged by running “220” bitstreams or similar. The maximum recommended bitstream is currently “200”. If in doubt email bitcoin.support@enterpoint.co.uk for a list of approved bitstreams.

Yeah, that didn't add up to me either. I was always under the impression bitstreams can't effect it's "power" or "voltage", nor would it change automatically even if you pushed it hard via overclocking. The worst that happens is invalids or errors in the output.
320  Other / CPU/GPU Bitcoin mining hardware / Re: So what is the consensus on how many 7970's can run on one rig ? on: September 20, 2012, 01:25:32 PM
Your limiting factor is usually the motherboard, since your will have to resort to risers on PCIe x1 slots, to make up for the lack of PCIe x16 slots.

Then comes the factor 7970 use 225-230w (6 + 8pin), so you quickly going to run out of cables and power even in the biggest of PSU's so needing two is not unusual for big rigs.

Different OS can give you problems, but as long as it's 64bit it should not be a limiting factor, if in doubt try linux.

The very nature of these boards also adds to alot of heat in a small space, so cooling this would be like having a 1-2k watt electric heater constantly on; I've had one of these in the past, they can heat up an entire apartment or small house by itself.

So most people should be able to do 4, but you could be able to go up to 8 if you go the extra mile. I can imagine trying to go beyond that is worth it with one rig. Split it apart and make another Rig. I don't know of many motherboards that even have than 8+ PCIe slots.
