I keep my xmr in a mymonero.com wallet. Last time I logged in, it gave me a message that I have to pay 10 xmr to import my transactions. What happened?
My old address is gone, and the wallet won't show my balance.

Edit: when that happened, I was using a Japanese VPN. I switched to a U.S. vpn, logged in again and my wallet works normally. Can somebody explain?

Sounds strange to me, but fluffypony would know better. He might be asleep right now so check back later.

Ok. I put that command to linux command line inside the folder where simplewallet is. Not to inside running simplewallet software. I gues you ment that. Looks like you are almost right. You just missed dot and slash at the beginning of the command. It should be this way.

But till there is some problem. What that triple means at end of the error message?

Are you entering the command all on one line with no extra spaces in between. If you have a line break after AbtF5Ps as shown above or any extra spaces it would not work

So like this:

Code:

$ ./simplewallet --generate-from-view-key 49bPEMu2NiJCDPAvzDDTJCfcRKcdSmB5P3XFbMbw7m1rJt7cotJeFJEZVhTFguYeQ4TNEvPwAbtF5PsJQ9iEKz8mH2WmQo3:794d99ba442931954d00de76218f62a85692fbffd544590a0f5d913149fed0a:lookwallet

My blockchain got corrupted when the electricity stopped. I resynced from scratch and it took about 24 hours. Previously I resynced from scratch a few times on the same machine on the same USB3 external hdd and on the same internet connection for 1-3 hours (it was on bitmonerod 0.9.0 tagged and before tagged, not 0.9.1). What could be the issue with the slow sync this time?

I'm not sure I'm understanding. Are you using the same version as before?

What CPU do you have?

I'm using 0.9.1 now. Previous times I was using 0.9.0 tagged and previous version (0.9.0 before tagged). Windows 7 64x. Mobile Core I7 (4 cores, 8 logical cores, 6 MB cash, with AES-NI).

Thank you for clarifying. We are looking into it.

I ran 0.9.1 again and it got to block 135000 in 43 minutes and block 270000 in 2 hours and 25 minutes. Then i checked my .bat file and the "--db-sync-mode fastest:async:10000" option was missing (fastest:async:1000 is the default and I'm using 10000, but it seems I deleted it by mistake). Then I started it again with the option added and it got to 135000 in 17 minutes and to 646069 in 2 hours and 25 minutes. That was the speed I experienced with 0.9 beta2. I hope I didn't alerted all the dev team. Great missive and great dev team. Congratulations to the new members. Keep the good work going.

Thank you for the follow up. We're going to take a look at whether there is a better default for the parameter, although higher numbers increase memory usage, so it may not be best for everyone to increase it.

That's what I expected too, but trying with 1000, 10000, 25000 and 100000 I can't see overall difference in RAM usage on my 16GB RAM system. It's using about 1 GB RAM on my system during sync with each option and most of it is shareable. After sync it's using 500 MB. The private working set (not shareable) is just 36-50 MB on my system. Also on my system there is a good speed improvement between 1000 and 10000, but going to 25000 and 100000 doesn't improve the speed more and it stays the same.

Your observations are exactly what is expected; smooth misspoke about increased memory usage. Increasing the sync interval just controls how much unwritten data is allowed to accumulate in the FS cache, but that doesn't affect program RAM usage. (He was probably thinking about batch size, which *does* increase memory usage.)
And yes, there's a practical threshold above which there's no longer any performance difference, because when the cache flush hits, there's enough unwritten data in cache to keep the storage device 100% busy until the sync/flush finishes. (It's also possible that your system's default settings have automatically started flushing the cache before your specified interval hits.)

Thank you for the clarification. I'll test if increasing the --batch-size helps the sync speed on my system - there's plenty of free RAM I'm not using most of the time.

binaryFate made this excellent post on reddit a few days ago to explain how ring signatures in Monero work (and a comparison against Bitcoin):

Quote

Here is a short recap, first how Bitcoin works and then the difference when you have ring signatures.

"Classic" signing as in Bitcoin: Whenever you want to spend an input (required when you build a transaction), you reference that input and produce a signature with the private key that corresponds to the address to which that input was sent.
Ring signing as in Monero: Whenever you want to spend an input, you reference that input PLUS some others with the same amount. Those additional inputs can be anywhere in the blockchain, recent or old. They can belong to dead people or their corresponding private key can be lost (just to underline they are not going to do anything active with you). Once you have this list of inputs (yours + the additionals), you create a ring signature using a private key. To any observer, this signature could have been created by any of the keys corresponding to the inputs. They have no way to know who the signer is, and therefore which input is actually spent in the list and which ones are "the additionals".

To insist that the process is entirely passive for others: they don't need to do anything, they can't even choose who will use their inputs as part of a ring or not. You can be the only user of Monero for an entire week and still create ring signatures as usual. You can also create ring signatures and therefore transactions on an airgap computer without any internet connection. (That should make it clear to you nobody else is involved in the process).

Ha - no response to the Monero mention. I think we all like Bitcoin and have high hopes that eventually it gains some level of privacy, but given the size of confidential transactions and the willingness of the community to add new semi-controversial features, it's not likely to compete with Monero anytime soon. No matter our opinions on the roadmap, there's a fuckload of work needing to be done on SW, LN, sidechains, eventual block size increase, etc. They've got a ton on their plate and that's without tackling mining centralization and privacy.
