Means that your reservation will be deleted after 5 days, if you not pay.
They let the reservation in my account for over 1 Month, now they say, 5 days is the max.


So no idea where they pull the 5 day's limit out. But seems that their customer protecion plan turns in Bitmine Protection Plan Smiley

Mastah

They announced some time ago that they had enough orders that people towards the back of the reservation queue would have no realisitc chance of ever getting a unit if they just waited until their queue position came up.  (Reservation queue was never a guarantee.)

They said for reservations that had no chance of every getting the option to buy, the reservations would be cancelled - but they would warn you and give you the option to convert to a paid order (which anyone in the reservation queue can do at any time) before cancelling the reservation.

Perhaps that is what happened here?

Could it be another site sharing the same IP address that is the target of the block?  Because of the way Cloudflare does SSL, you can get a list of the other sites sharing the same IP address by looking at the subjectAltName extension in the cert.

I notice that bitcoinarmory.com is using Cloudflare.  Since an unauthorized change of DNS to point to Cloudflare was implicated in the recent attack on bitcointalk, it would be nice to have confirmation from etotheipi that bitcoinarmory.com is supposed to be using Cloudflare.

The Certificate Patrol plug-in for Firefox looks interesting - it's supposed to tell you whenever a site's cert changes. https://addons.mozilla.org/en-US/firefox/addon/certificate-patrol/

I've only just installed it, so I'm not sure how well it works in practice - but judging by the screenshots it looks like it saves the cert of every site you visit (not just a fingerprint) so that on detecting a changed certificate you can actually view both the old and new certs.

Of course, it's not that useful because in reality you often don't have enough information to determine if it's a legitimate change or not.

What would happen if the key suffers several bitflips? It will stop working and you can't even figure out where the errors are.

A possible improvement is to store hash checksums sector by sector elsewhere, so assuming there are no more than two or three errors per sector, it would be feasible to check each sector and locate the errors.

Paper backups (n-of-m if necessary) are probably the solution to USB drive failure, regardless of the failure mode.  Although I did buy some SLC USB drives on the basis they might be expected to have better longevity than the usual MLC devices.  Haven't used them for anything yet, though.

It strikes me that whatever units we use, the only way to avoid errors of sending orders of magnitude too many coins is to confirm the value in (approximate) fiat.  We're a long way from a situation where most Bitcoin users have an inuitive feel for sums of Bitcoin - and this is only in part due to the rapid price moves.  This is true even without a unit change - the latter will just add confusion.

Assuming we're agreed that fiat confirmations are useful as a sanity check (Bitcoin Wallet for Android has them and tbh I think all online clients should) - it does raise the question as to what rates to use, but moreover how to obtain trusted exchange rates.

Although, with offline wallets ideally you'd want trusted sources of signed exchange rate data.  If the offline computer could verify the signature and timeliness of exchange rate date saved along side the unsigned transaction, then you could guarantee that the user would be presented with accurate information when verifying the transaction.

Apropos of nothing, I'll contribute my experience of this problem:

To the best of my knowledge, I have had precisely two unclean shutdowns of my Mac whilst Bitcoin-QT 0.8.x was running.  In two out of two cases, it triggered a rebuild due to a corrupt database.  So I find it interesting that this problem is actually difficult to reproduce - I guess I'm just unlucky.  (This is 10.6 on a MacBook Air.)

What really surprised me, though, is that on the occasion of the second of those unclean shutdowns (the OS X UI froze and I had to do a force power off) not only was I not actively using Bitcoion-QT at the time, but I am 99% sure that I had no network connection, and hadn't had a connection for several minutes.  So it seems pretty unlikely that it was a pathological case involving an interrupted DB transaction.

None of the above makes any sense to me, and it is, of course, quite possible just a fluke occurance - but on the off chance it gives anyone any ideas I thought I'd post it anyway.

270  Bitcoin / Armory / Re: Offline Laptops on: November 27, 2013, 11:39:47 PM
For reference, I do exactly this:  keeping a laptop in a safe deposit box.  I visit the bank and hang out in the privacy room for a while when I need to sign a transaction.  It's encrypted and has no battery.   The price for the larger box isn't a lot.  I think it's about $90/yr versus $50/yr for the smaller one.    Either way, if you're going to the effort of putting your laptop in a safe-deposit box, I"m sure $100/year isn't going to break the deal for you.

At my bank, the privacy room has an outlet.  It's because they have one of those calculators with a small paper/receipt printer in the room which requires power.  I don't know if that's normal, I didn't shop around. But, I made sure beforehand that the computer works with the power cable but no battery.  

I asked the bank manager if they had the option of requiring two signers at once to access the box (perhaps, to open a safe-deposit box for the company).  They misunderstood thinking I wanted multiple signers.  We later clarified they don't have any way to enforce having multiple people present to access the box, though they do keep strict records of exactly what time the box was accessed, and ID the person who accesses it (and the employee who helped).  Not ideal, but at least it still requires collusion of one of the signers and a bank employee in order for tamper evidence to be skipped/destroyed.  

Having the ability to put the wallet encryption key on a USB key is interesting.  I like it for the offline computer (for the same reason I like it for the full-disk encryption).  But for hot wallets, I'm not sure I like it as much.  It's a lot easier to write a process to copy key files every time new media is inserted than to install a keylogger remotely (though, both are still non-negligible risks).  If you do it, you'd have to make sure that removable media is thoroughly protected, so that only your user account can access it and no other system users (which is possible, but I don't think it's default, and may be inconvenient to setup and use).

Sorry for slow motion conversation here, but....

Obviously in many ways the ideal solution to your multiple signatories problem is to have multiple people hold individual safe deposit boxes, and use multisig.  Now, if you want to be really secure - perhaps a really high value wallet where it's important to guarantee that none of the box holders can subvert the system by tampering with the laptop - then having a laptop in each of the boxes is justified.  But in some cases it may be an acceptable solution to go for smaller boxes and a single laptop - particular if larger boxes are hard and/or expensive to obtain.

Consider the case of a high value wallet held by an individual, where the n-of-m boxes - perhaps even in different cities - are all held by the same person, but are there in part to slow down withdrawals to make it considerably harder to successfully cooerce the owner into a withdrawal.  In that case perhaps USB keys in safe deposit boxes might considered adequate.

BTW, you're lucky to get a decent sized box for $100.  In the UK, banks are pretty much getting out of the safe deposit business.  Increasingly, banking is electronic; it's no longer about storing large reserves of cash in secure vaults, so increasingly as they move to new premise they no longer have the kinds of vaults with space to store customer boxes.  At most, they need somewhere secure to store some cash to top up the ATMs - but bank vaults are a thing of the past.  I pay more than double what you do for a box at a dedicated safe deposit facility - and it's not big enough for a laptop.

It's true, it depends on the shape of the boxes, too.  Although mine doesn't, I believe some faciiities have small boxes that have a decent area but a very small height.  I assume these are intended to allow documents to be stored without folding - but would would probably work well for storing a netbook or ultraportable laptop, too.

Microsoft and Apple produced software and computers; Google produced an Internet search engine. If you now buy stock in any of the three, you're investing in some of the largest companies in the world. There is underlying value in those companies that warrant value in their stock.

Google is an interesting example because they produced a free search engine.

If you look at the combined valuation of the Googles, Facebooks and Twitters of this world - companies whose main business model is to give away free services funded by advertising - it's not at all clear that the Internet advertising market is big enough to support these valuations.

The fact that these stocks made a bunch of people rich doesn't mean they're not in a bubble.

OTOH, if the entire shipping department was farmed out to Bob's Express Mail, or the like, then there would be issues if such wasn't fully disclosed beforehand

No real world business decides in advance in an irrevocable way who will provide shipping logistics.  The real world is that businesses subcontract functions as necessary, and the identities of the contractors will change from time to time.

This is a dirty little secret of rogue telemarketing firms. And it's
probably happening right under your nose.
 
In my opinion, it's downright fraud! Make sure the telemarketing firm you work with
NEVER sells your leads to another company. Get this in writing.
 
You see, a lot of telemarketing firms have you sign lengthy contracts, and when a list is
exhausted from repeated calls, they need a way to continually produce leads. What could
be easier than to take a campaign you paid for and give the leads to someone else?
 
This happens more often than you'd expect.

Legal or not, I don't believe many bitcoiners think kindly of having their vitals distributed to an unknown third party, especially by a Bitcoin entity that stated in their ToS that they wouldn't do such. I don't believe a single Bitcoin miner ever thought that one day they would be receiving a call from a telemarketer soliciting 20% off coupons, or whatever, safely assuming that such an occurrence would be über-slim, consider we're speaking about the belief systems of most bitcoiners.

By your interpretation, it would be illegal for BFL to write your name on the shipping label because USPS is a third party.

Further, if they use a third party logistics company to package up and ship the products, they would have to give the names and shipping addresses to the logistics company - by your argument they can't do this.

In all these cases those are subcontractors, not third parties, by any common sense interpretation.

Why the delay:
CryptX has not paid me yet, that lead to me being unable to pay my contractors which then stopped production.
After a lot of back and forth i managed to convince them to finish the Job.
Cryptx didnt pay you till now... i dont see a reason why they should do this.

Uhm, what? You don't see a reason why CryptX should pay his debts? Can you elaborate?

Lost in translation I think...

Don't see a reason why he WOULD do this...
i.e. Unacceptable behavior

I meant i dont see why "they should do this"... meaning why they dont pay burnin all the time. I dont see a good reason for that.

That's what I meant. To a native English speaker in that context it still reads "why should they pay".  I knew you didn't mean this.

Hm... didnt thought that. I referred to "didnt pay" what i dont understand why they didnt. And its read as "pay" that i dont understand why they should. Its maybe how you worth words in sentences and might be different. Strange, but i see it can be misread.

Sebastian: mainly, in modern informal English just use 'would' almost everywhere you were taught to use 'should' Smiley

Use 'should' only when you want to explicitly convey a sense of obligation (sollen) e.g. ("He should do that" = "Er sollte dass tun")
