1  Other / Meta / How to change password if I have forgotten it? on: September 22, 2022, 11:25:11 PM
What is a safe way to reset my current password if I have forgotten it? I am still able to get in from an old computer where I had stored my password in the browser. I seem to recall that trying to reset via email may cause problems and could in fact lock me out.
2  Alternate cryptocurrencies / Service Discussion (Altcoins) / How to claim Bitcoin SV from old BTC private key using online wallet? on: July 02, 2019, 03:27:42 PM
I just cracked open an old paper wallet with an old Bitcoin private key from back in 2012. The key was generated using MultiBit Classic, long before it was called "Classic".

I had no problem importing the key into Bitcoin Core and Bitcoin ABC wallets, and was able to move the BTC and BCH into modern wallets.

I am not sure what to do with the Bitcoin SV. Right now it is worth around $190 each so I don't want to just throw them away. I spent about 30 minutes Googling for an online Bitcoin SV wallet that would allow importing the key. Can anybody recommend such an online wallet? If possible, I don't want to install any Bitcoin SV wallet on my computer or phone.
3  Economy / Exchanges / Localbitcoins TOS change on May 25, 2018 on: May 16, 2018, 11:44:24 PM

Anyone have any additional info about this, particularly in regards to ID verification?

ID verification We don't require ID verification for all users, but in some situations you may be asked to verify your ID with us. We will ask you to ID verify in the following situations:

  • After trading over certain volume limits and when advertising - It is our top-most priority to ensure that LocalBitcoins is a safe and securebitcoinmarketplace and that no one is able to use our service for money laundering or other unlawful activities. Most fraud on LocalBitcoins stems from users attempting money laundering. We believe that taking a strict stance in this regard is in the interest of our users and important for our brand as a trustworthy marketplace.

Exactly what are the volume limits? Anyone have any idea?

4  Bitcoin / Bitcoin Technical Support / Are these peers with triple connections valid? on: November 04, 2016, 11:49:41 PM
Every now and then these peers connect to my node with 3 connections each. They don't take up much bandwidth but they hold the connections open for a long time.

They claim to be SPV clients. Are they valid peers and why do they need 3 connections?

Is there an easy way to ban multiple connections from the same IP, without say, doing something drastic like blacklisting AWS IP addresses.
5  Bitcoin / Bitcoin Technical Support / Quickest method to initialize new bitcoind node on: December 01, 2015, 12:34:07 AM
Can someone tell me what is the best practice for initializing a new bitcoind node quickly? Do I really need to wait 2 days for the blockchain to be downloaded and validated before the node is operational? As far as I can tell most of the time is spent not on network resources but on CPU resources, at least for the hardware I am running (Azure & Amazon EC).

If I already have another fully initalized node that I trust, is there anyway I can just copy the blockchain database from a trusted node over to the new node (bypassing all the time consuming validation)?
6  Other / Off-topic / How much data does your car track? on: April 24, 2015, 11:01:28 PM
I took my car in for a scheduled service and without me asking the dealer apparently gave the car a software update. The software that runs the navigation, radio, driver assist, cameras and what not now behaves differently. It seems a lot smarter than before and I am somewhat concerned that it might be tracking and reporting my movements to some central database. It is a fairly new car with a lot of electronic gizmo and I am in the US. It seems to be connected to some network because I do get live traffic updates that enables the GPS to bypass traffic jams.

Does anybody here know exactly how much data a car tracks - say those equipped with OnStar or ConnectedDrive? I am guessing that this forum might have a number of privacy conscious readers who might know the answer.
7  Economy / Service Discussion / Localbitoins - Offline traders with a GREEN status on: March 24, 2014, 10:57:31 AM
Yesterday I opened trades with a bunch of traders who had a green dot next to their names. The type of trades caused my BTC to go into escrow immediately. However the traders appeared to be offline and did not respond. I had to wait 6 hours to get my BTC back after the trades auto-canceled.

What's up with all these offline people with green dots?
8  Other / Meta / 2-factor authentication for forum login? on: July 07, 2012, 12:36:01 AM
I just realized that many investing, lending and depositing activies currently taking place in the forum rely heavily on the transacting parties' forum identities for authentication. I'm refering to those operations that are mostly PM and message based, without the benefit and support of an external website that has a login. Under these circumstances some forum logins could be as valuable as bank logins to a potential thief.

Would it be feasible to add 2-factor authentication for forum logins? Optional, of course. I was thinking something along the lines of Google Authenticator or B-Y-O-Yubikey. If there were a demand for this it could be made available only to Donators and/or VIPs so the implementation costs could be recovered as more people would donate.

Does this make sense?
9  Bitcoin / Mining support / HD 7750 on Windows 2008 R2 headless - unexplained hashing slowdown on: April 05, 2012, 03:50:13 PM

I colo a rack of 2U servers as part of a side business. Electricity is "free", because I already pay by the number of 20 Amp circuits to the rack. To support the bitcoin network, I decided to outfit some of my servers with HD 7750 cards because they fit in the unused 16x slots and don't require power cables.

These servers are headless. With the new 12.2 and 12.3 drivers Diablo miner can see the GPUs and I can hash without a monitor or resistor plug. The problem is this:

1) I have a startup script where Windows will auto-login and start up the miner. I only get a 40 Mhs.
2) Similary starting the miner from remote desktop session I get 40 Mhs.
3) When I connect to the exisitng session using VNC (or any other console based remote control program) the hash rate jumps to the expected 120 Mhs.
4) Similarly when I start the miner from a VNC session I get 120 Mhs.

Another observation is that GPU Caps View shows a blank GPU tab when the rate is 40 Mhs (while this is happening it still sees the correct OpenCL information). When GPU Caps viewer sees the GPU, then I get the full 120 Mhs.

Can someone explain what is happening?
