Can your code handle testnet coins?

Yeah, $30K around the house sounds like a lot.
It not just "$30K around the house". He was widely known for doing cash deals nearly daily for a long time. Keeping cash at home in a safe or under the proverbial mattress, when nobody knows about it is safe and sane. It is a completely different story when everyone and his dog knows that he was a cash operator.

What kind of miraculous force protected him from robbery for all those years?

if you live in a good area and are wealthy its not unreasable to think some people have cash or even gold well in excess of 30k

maybe  he took precautions ,had it stashed in a safe or split up in various locations around the house

someone who is practically famous for doing big deals face to face for the last few years would need to have operational cash on hand in case the phone rings and someone wants to dump some cheap btc ASAP to take advantage of the situation and make a profit etc
Yeah right. Personal face-to-face trades with anonymous people, done nearly daily for couple of years. With no single instance of violent crime.

Maybe someone will dump some bricks on your head to make you understand what's wrong in your picture.

When did she say it was "hidden?" I heard "from around the house."

In my house, at this moment, there's cash in my wallet, in my wife's purse, in the safe, in a drawer and probably a couple of other places I've forgotten about. The amounts are all under $1000 but I'm sure if I was targeted as Burt was it would all be confiscated and I'd describe it in the same way.
There is a miscommunication going on in this thread.

I'm going to guess that most of the posters here don't remember the days when the delivery vans used to have "Driver doesn't cary cash" painted on them.

Again the interesting and unusual part isn't whether it is "legal" or "illegal" to keep that much cash at family residence with small kids. The question is: is it safe and sane? The people who really handle that cash on the daily basis treat it in a way similar to dangerous explosives. Because cash first of all attracts crime.

I'm thinking that maybe BurtW wasn't telling his wife everything, maybe he kept additional job for cover, maybe he tried to keep double and/or cooked books and gotten over his head in it?
Keeping $30,000+ in cash on hand when you're trading bitcoins makes sense to me.
At a family residence with wife and small kid? I think you are either unmarried/childless or homicidal/suicidal/infanticidal.

Edit: OK, one possible thing came to my mind. Maybe BurtW was sane, wore body armor when going Bitcoin trading, had a armored car with run-flat tires, and other accessories of the cash operator. But maybe he hired/cooperated with non-licensed body guards or two-timing body guards. And those guards were involved in something obviously illegal and BurtW looked to the investigators like he's working for them as a bagman and not vice-versa?

It's also, from what I've seen, not clear how much protection ECC actually provides... all data covered by the protection is in the same domain for row aliasing, and typical protection only provides single error correction; soo...
Single Error Correction is usually Double Error Detection (SECDED) or even better (Chipkill)

For the intECC case I presume that the internally-erroring chip/module will return something obviously outrageous (all ones, 0xDEADBEEF, maybe something configurable?) so at least the crashes should be obvious and harder to exploit than bitflips.

For the classic ECC all hardware that I know will do Machine Check Fault/Non-Maskable Interrupt and then SIGBUS or equivalent.

I hope this exploit will get sufficient publicity that I can stop having to think about such things like bitsquatting  and similar nonsense.

Ever since the first paper on this subject was published I've been running hosts doing anything important with overspec memory running underclocked, as an additional mitigation. A couple percent performance isn't worth any risk of corruption.
I've been fortunate enough to be bitten by the bitflip early in school, and after that I never did any serious work without parity or ECC RAM. I always take care to verify the operation of machine check exceptions and properly configure memory scrubbers.

The copy of yaccpar in my project lost one bit in this line ("!" became " ", 0x21 to 0x20):
for( yyxi=yyexca; (*yyxi!= (-1)) || (yyxi[1]!=yystate) ; yyxi += 2 ) ; /* VOID */

changing it to
for( yyxi=yyexca; (*yyxi!= (-1)) || (yyxi[1] =yystate) ; yyxi += 2 ) ; /* VOID */
which still compiles and even kinda-sometimes-runs. After that I was inoculated to ever trusting a computer without memory error detection or correction. The school computer that produced this error actually had parity DRAM chips, but the school's vendor did a "leg lift" on it, i.e. bent a pin upwards to disable parity error interrupts.

Well you obviously want to be discrete about having that kind of cash in your home. I am sure they were not advertising the fact that they had cash.

His wife also mentioned her testimony against civil forfeiture laws that the money was taken from various parts of their house and from their safe, which implies that they had money hidden in multiple places, so if they were to get robbed then the criminal might find some small amount of money, take it and then leave.
Without additional information my suspicion is on some marital problems or addiction or something other cause that I can't think right now. Money hidden in multiple places at home? With young/early school-age kids living in that home? It just doesn't compute. Kids at that age are so nosey that you cannot hide anything from them, if you raise them normally.

The fresh-flower market that I've mentioned before had one/two nearby jewelry/watch/buy-sell-gold kiosks. One day one of my elementary school classmates came to school with gold bars and started giving them away (I'll say 1/4M$ at the current prices). Some observant janitorial/custodian lady collected them back and alerted the administration. The real reason was alcoholism of the parents of that kid.

People and families handling cash/cash-equivalent-valuables have everyday rituals that assure their safety, mostly from common crime. I just can't seem to find such "safe-normalcy" I would expect in the BurtW's family or any other family that lives with and runs cash-intensive occupation.
7  Bitcoin / Bitcoin Discussion / Re: BurtW arrested on: March 16, 2015, 01:44:10 AM
Well I would say that would not be all that uncommon for people with a lot of money, as much as they apparently have, to keep such a large amount of cash at home.

A 'sane' reason to keep that much money at home would be for bitcoin trading purposes, as it would probably be a bit of a hassle to have to go to the bank every time burt wanted to buy or sell large amounts of bitcoin, plus the fact that making a lot of cash deposits and withdrawals out of a personal account (he wouldn't have a business account because he was only doing it as a 'hobby') is a good way to get your bank account closed.

I am not sure what exactly Burt's wife's company does, not what the client does. Both the businesses names were redacted (and the locations Huh ) in a letter that she wrote and published in a different section on her site. I would say there is a good chance that it would be difficult/impossible to determine exactly what they do.
I understand not using banks. I grew up next to the wholesale fresh-cut flower market that was open 4am-7am, for the delivery at 8am-9am, which was also before the bank hours. I think I mostly understand people dealing "cash only" and having suitcases full of them. But never at home! This is dangerous, you paint a target sign for yourself and the family. And I'm not taking about "jackbooted government flunkeys", just a regular old-fashioned violent crime. Neither BurtW nor his wife seem like random naives or Bitcoin cultists/evangelists.

I don't think there ever will be enough information available to determine the sanity of their actions. The best we can hope for is to determine legality.
Well, legality is rather boring (to me) subject. The legal details could change in an instant. I'm interested in "what they were thinking", what kind of operation they were running.

The amount of bitcoins is more impressive: equivalent to $ 200,000 at current price. So, this doesn't surprise me. Also, you should consider Bitcoin is cash too (this affirmation is in the whitepaper).
I'm not about the current market value. I know families who have way more than that hanging on the walls in the open as painting which appreciated in value.

I'm trying to find a sane reason to keep this amount of cash at home in their circumstances. If  I can't find sane reasons I'll have to look for insane ones.
9  Bitcoin / Bitcoin Discussion / Re: BurtW arrested on: March 16, 2015, 01:18:36 AM
There are a number of legit things that would have caused them to have that kind of cash in their home. Primarily it could be for bitcoin trading. They also apparently have a lot of money so it could be the equivalent of their "emergency" fund.

His wife said on her website that one of her client's (work) sites were searched which caused the client to fire her company which cost her company millions of dollars. If they have millions of dollars to lose then they probably have enormous amounts of money. If your company makes millions of dollars then $30k really doesn't sound like that much.

I do think that they probably do have the resources to make heads roll, assuming that Burt really was not involved in anything that was actually illegal (meaning he was not involved in SR2, or any other dark market site at all). It appears that a number of people make mistakes throughout the case, most interestingly the magistrate who apparently authorized search warrants without probable cause to seize attorney-client privileged information, and then the proper procedures were not followed when such information was taken
I kinda don't mind "legit" or "illegit". I'm interested in "sane". I can fully understand the grey market economy and life (all the way back to the plight of European Jews during WWII).

Keeping 30k$ at home with no obvious use or as an "emergency fund"? This just doesn't seem sane. Or it is a symptom of being disconnected and alienated from the extended family, neighbors, friends, etc.

Is there any more information about "wife's client's (work) sites that were searched"? I don't care about specifics, just the general business sector and the purpose of keeping funds in cash there.

Again, I'm not interested about legality or illegality. I'm more about the sanity and purpose of the lifestyle.
10  Bitcoin / Bitcoin Discussion / Re: BurtW arrested on: March 16, 2015, 12:25:22 AM
The only thing I can think of is buying and selling large quantities of Bitcoin. That is kind of strange but not unheard of entirely. I used to have an uncle (he died 30 years ago) that lived through bank failures a couple of times. He didn't trust banks. He kept all of his money hidden in a metal box somewhere in the woods behind his house. When he died several of my relatives destroyed the land behind the house looking for the box and never found it. That's a rare case but who hates banks more than Bitcoiners?
Yeah, I understand. But keeping such cash at your own home and not in some pre-arranged location away?

Our ex-CFO had a relative who died approximately in 2000, never had SSN (edit: or maybe he had it but never used it as an adult) nor bank account, did all transactions with suitcases of cash. But collecting his estate was a multi-week trip around the country to visit all the places where he stored it (mostly regular safes/storage as well as some hidden caches on his properties).

Edit: I know that e.g. European illegal immigrants to the USA, especially those who don't speak English well, tend to store/deposit their savings also in cash with the neighborhood groceries/restaurants/bars/bodegas/convenience stores. Sort of like Leon: The Professional . But storing at home?

11  Bitcoin / Bitcoin Discussion / Re: BurtW arrested on: March 15, 2015, 11:55:26 PM
$30,000 in cash from their home
30k$ at their own home? Wife is a lawyer/paralegal? This is getting interesting.

Anyone care to speculate what would be the use of 30k$ to be kept at home? AFAIK nobody in the family was running a cash-based small business. I know people occasionally keeping much more than that at home, but they are in the cash-intensive business not involving Bitcoins.

Edit: E.g. I used to know a woman real estate agent who used to keep way over 100k$ in small bills very close to herself at all times. Her specialty was buying highly-appreciated (by value) but decrepit (by condition) real estate from alcoholics and other addicts.

What would be the business model requiring to keep 30k$ in cash at home? I don't care if legal or illegal. Please give your guesses.

Edit2: I also remember CFO of some rather large company keeping that amount of cash on hand at all times when his company was involved in lawsuits (not him personally) and the company used to employ many blue-collar workers living paycheck-to-paycheck (or paypacket-to-paypacket).

Thanks for posting this.

Anyway, anyone who was using non-ECC memory for the financial applications was already in the state of sin.

The good thing is that I expect the hardware quality to improve after this exploit becomes widely known. New DDR4LP standard apparently already includes the mitigations/workarounds.

One thing I really liked was intECC DRAM chips: DRAM which is pin-compatible with the current non-ECC DRAMs but internally uses ECC. This will allow many people to preserve most of their hardware investments (mostly laptops) by just replacing the DRAM modules.

I have downloaded OS X Server for one of my Mac Mini's and one of my MacBook Pro's I'm using now.  I have several domains through  The domain names are the same; just different suffix's; et al, .us .org .com etc...
1) Install OSX server only on actual server (Mini) computer. Don't install it on portable notebook computers, it severely reduces performance and battery life.
2) With a simple cable modem + Airport Extreme you emphatically don't need a separate firewall, the trivial one already inside the base station is completely sufficient
3) Forget about registering and configuring domains for now, just configure and use "Back To My Mac" service until you have sufficient understanding of public vs. private IP addresses and Network Address Translation and port mapping
4) For now use the OSX server as a normal house computer that is on 24*7, download the server documentation from Apple and skim it (don't read thoroughly). You'll just need to roughly remember what kind of information is available in the Apple references. Many well-meaning advice givers on the forum give complete bullshit information with respect to Apple technologies and you'll need to be able to quickly sanity-check it with the actual references what is true.
5) 1&1 has a proprietary DNS manager web panel that is rather self documenting once you really understand the networking basics in (3) and (4)
6) obtain the actual precise information about your ISP business account settings: is it single IP or block of several consecutive IPs, is it just IPv4 or dual IPv4 & IPv6. Don't post the uncensored details here, don't post your real domain names here, use placeholder names and numerical values. This forum is full of sharks that will own your network as soon as you disclose sufficient information because everyone knows that you are just a beginner setting up your first network.
7) Create a separate thread in Technical Support with a meaningful title e.g. Creating remote-accessible mining farm using Apple technologies. We'll help you more there.
14  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: March 14, 2015, 01:16:15 AM
I'm setting up one of my Mac Mini's to gain access to my rigs when I'm away.  I'm going to use OS X Server to connect to the Mac Mini and the rigs in turn.  Thank you for your input.  I was talking to you and two others at the same time.  I was thinking about sing "Back to my Mack" to gain access.  Seems to be a lot involved in that with port mapping.  So, I'm doing my homework on Mac OS X Server.
Stay safe, man!

I presume you currently have a cable modem in front of your Apple Airport Extreme. When you move also use a modem for the ISP access. If the new ISP forces you to use a "residential gateway" learn how to configure it to "bridge mode" and continue using Apple-only networking. Avoid "double-NAT" and other hacky configurations, there is a frightening amount of misinformation on various support and discussion boards.

At least you are aware to avoid following misinformation from Windows users.
Currently what is running the NAT to assign IP's to your network devices? Your router or are you already running ICS?
My Airport Base Station Extreme tells me it is presently set up for DHCP and NAT.  I manually assigned my rigs an IP address in DHCP.  I do not use Windows for ICS.  I have all Mac devices other than my mining rigs.
15  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: March 13, 2015, 06:06:04 PM
I'm wanting to set up my network to be able to access my rigs while I'm away from home.
From the rest of your post I can tell that you don't understand what you are doing with your network. If you keep opening ports the end result will be that the remote hackers will have better control of your network than you.

With your level of knowledge the only way to do it is to keep one Mac permanently at home and configure your Airport to allow only Apple Remote Desktop to your at-home Mac. Alternatively you could use "Get To My Mac" service from Apple.

After that you can buy the Mac OSX Server upgrade from Apple (less than $20) and set up your own VPN and other services that are described in the OSX Server documentation. Reading the OSX Server docs will also help you to learn and understand the networking basics, both general IP and the Apple specifics (like afp:// not aft://).

No matter what you do you will have to have a permanent (or nearly permanent) computer that monitors your home farm over the LAN. If you don't yet have a spare Mac at home than buying a Mac Mini and installing a server upgrade on it is the best way to spend time and money.

Have fun, just don't become another basket case Mac user with home network owned by hackers.

Edit: Ha, ha! Our posts were seconds apart!
Should I just set up one of my Mac Mini's to stay on all the time and access it via "Back to My Mac" to have access to my rigs?
Listen to your own internal voice!
16  Bitcoin / Development & Technical Discussion / Re: Is someone monitoring large parts of the network? (evidence+firwall rules) on: March 07, 2015, 09:27:46 PM
Or maybe some kind of NAT problem is going on (i am on a full cone NAT here). Or maybe this is all stupid what I am talking about. I will double check shortly.
Ah, so there is a NAT device involved here. This basically invalidates all your previous observations, as they can be explained easily as the errors in the NAT implementation. Especially if somebody advertises "full cone NAT" (only relevant to UDP) when interfacing TCP application.

Please do us all a favor and tell us the manufacturer/model/version information for your NAT box. Everyone could then just add it to they "do not use/buy" list.
17  Bitcoin / Development & Technical Discussion / Re: Is someone monitoring large parts of the network? (evidence+firwall rules) on: March 07, 2015, 12:40:19 AM
Yeah, but this would not explain why those nodes are neither relaying TX, nor replying to BitcoinPing messages, ...
Seems they save bandwith aggressively and prepare for something bigger.
OK, if they don't behave like a normal client behind a NAT that definitely confirms your suspicions. Large scale NAT farms are popping all over the world right now, and many programs tend to go berserk when receiving connections from those.
18  Bitcoin / Development & Technical Discussion / Re: Is someone monitoring large parts of the network? (evidence+firwall rules) on: March 06, 2015, 11:59:14 PM
This, on the first sight, looks to me as a large scale monitoring of the bitcoin network.
How about another hypothesis: an head-end of a CG-NAT ( device for some large French MVNO ( or some similar arrangement like Orange FunSpot (Free WiFi Internet access service).

Reverse engineering was how we got PC clones - but funnily enough IBM didn't go out of business did they?
IBM PC was not reverse engineered. IBM published very detailed technical reference manual that contained entire schematic of the circuitry as well as full assembly listing of the BIOS. The details of the IBM PC platforms (classic, Jr, XT, AT & PS/2) were never secret.

Please don't mix up reverse engineering with various clean-room design methodologies.

I will however believe that there were people who were paid to pretend to do reverse-engineering and probably some of them were even paid to swear to that under the penalty of perjury or create an "alternative construction" that served as a proof of reverse engineering.
20  Bitcoin / Project Development / Re: [ESHOP launched] Trezor: Bitcoin hardware wallet on: March 05, 2015, 07:42:58 PM
The devices are produced and packed in batches. Even if there was some unique code embeded on the hardware,  we would need to have a unique number on the package associated with it. there is no such code on the package of Trezor.
I trust you and I'm not claiming that you are trying to track the users of Trezor. (Plural "you", meaning "your company and associates", not "you personally"). I'm more interested on the possibility of correlation attacks done by somebody else on the users of Trezors, especially those users willing to connect the Trezor to a non-trusted and not-verified computer.

I'll repeat my question:

Is there any publicly available information or speculation about the SoC chips you use that would either exclude or confirm the presence of undocumented storage? IIRC the devices you use support "USB on-the-go" which is a fairly complex protocol. Do you even heard any substantiated rumors about the undocumented features of your chips. I've worked with some much older SoC chips where it turned out that OTPROM and ROM memory was in reality just EEPROM protected against write by convoluted trickery in the software drivers (can't recall the exact manufacturer at this time, later acquired by Rainbow Technologies).
