I have four GTX Ti750s and two R9 290x as well, but only will bundle them if selling a bunch of what is listed above

Message:
Everything works, but has been used. Almost everything has original packaging and cables. I'm willing to cut much better deals if you want to buy a bunch of this stuff instead of individual items.
I'll accept Bitcoin, Litecoin, Paypal, or Cash. I live in Las Vegas. If you're local and I don't have to ship it's definitely preferred.
I haven't really looked at what this stuff is worth, but I imagine I'll deduce it quickly from your offers ^_^


EDIT:
I was hoping to sell bundles, but most people want individual items. I've decided to just sell everything on Amazon.

Little bit more information. There's a TSQL connection upon opening the executable (password.txt). It goes to 93.174.90.67 on port 7657 which a quick lookup shows the Location: The Hague, Netherlands
5  Other / Beginners & Help / Re: I just got this email, looks legit, right? on: January 07, 2014, 12:08:30 AM
Yeah, I got the same email. It looked interesting so I opened the password.txt which is just the string "n0^jO2eG,73gN48" without quotes which is of course not the password.
The password.txt is a UPX compressed .exe and decompressed it's a PE.
6  Bitcoin / Project Development / Re: new Bitcoin Faucet by LaunchKey, a security company on: December 05, 2013, 10:22:30 PM
when will this be integrated with a bitcoin wallet?
I have actually built a bitcoin web wallet protected with LaunchKey. The front end is being cleaned up, the server backups set up, and then a security audit before I can put it live.

I have tried it. Seems like quite an elegant solution.
I don't like the fact that if someone steals my phone, they can log in with my account, though...
Also, when are those payouts made? And how much does the faucet give per person?
Thank you very much.
It's true that if someone steals your phone you could be in bad shape. You would want to immediately unpair from our site. Fortunately, you would probably notice your phone missing more quickly than most things and if it's just an additional factor access wouldn't be automatically granted. Your phone can also be locked and LaunchKey itself has additional factors of authentication that could prevent it being used during theft. Geo-fencing would allow you to put geographical coordinates where you could login. A combo lock would be a knowledge factor needed. A device factor would be a bluetooth device you need like a fitbit that needs to be in proximity to authorize. There will be many more factors to come.

edit: Forgot to answer you second question. The payouts are made immediately if it's a coinbase address, otherwise it'll go out in a batch every few hours to save on transaction fees. The amount right now is 0.00005460 or about 5-6 cents worth.

Passwords are awful. You should check out LaunchKey. It's a passwordless multi-factor (possession, inherence, knowledge) solution. If you want to see it in action and get a feel for the user experience you can use this wallet: https://faucet.launchkey.com
8  Bitcoin / Project Development / Re: I need a faucet installed on my website on: December 05, 2013, 05:23:18 AM
Rather than username and password (which suck) you should use LaunchKey. There are plenty of open source faucets available though. Just do a quick search on this forum.
9  Bitcoin / Project Development / new Bitcoin Faucet by LaunchKey, a security company on: December 04, 2013, 11:01:31 PM
I'm a co-founder of a security company in the Authentication space that allows passwordless authentication using your mobile device. It's a convenient multi-factor solution that's better than text codes or hardware tokens and reduces the liability for the places that use it. We share a lot of common ground with the Bitcoin community in the desire for strong security and being very privacy focused. For example we don't keep any user information and even the email address used for pairing a mobile device is one-way hashed.

We are currently partnering with US-based Bitcoin exchanges such as Coinsetter and also we've been paying out security-related bug bounties in Bitcoin since June.

Half of our company has been into Bitcoin for a very long time and when we first started getting into it there were faucets. So, we've decided to give back in that same way and have built a faucet for users to get some free bitcoin. Please check it out and give us your thoughts!

SQRL seems to have some gaping holes in the design: http://security.stackexchange.com/questions/43374/could-sqrl-really-be-as-secure-as-they-say
Check out launchkey instead: https://launchkey.com

As far as that rant goes. I think digital signatures can be done in HTML5 within the browser without a plugin. Although I have seen plugins for specific identity solutions that deal with browser keys, so perhaps it's difficult.

Amir (I assume you're referring to as IdiotParade) and I haven't spoken since April of last year. I don't know very many of the details on what went down, but it seems he made some grave mistakes regarding the Bitcoinica fiasco. From my interactions with him he seems like a very hard-working and idealistic individual.

The Britcoin project I only hosted the alpha for about 2.5 months from March 2011 to the beginning of June 2011. I had consulted many major law firms in the US at the time on the legalities of handling the project. Amir had wanted to make a trustworthy and security-focused exchange, so he wanted financial backing with a reputable company supporting the project.

One law firm stated they would give their legal backing but would require a $10MM retainer. Another firm needed $50,000 just to come to a decision whether or not they would be able to give their legal backing. The reason we wanted a major law firm's legal backing was in case anything were to happen with the (at the time) extremely uncertain currency involving the company's legalities we would feel better protected. Unfortunately, the legal costs were far more than we were willing to allocate towards what was a personal pet project of mine. As such I had to withdraw my support and Amir continued on.

Thought I'd provide a little bit more information:


Stack:
The production stack will have HAProxies that manage the database, and instances underneath. It's Nginx, Uwsgi, Python.
Beta is currently on AWS but we plan on migrating to the SuperNAP, a Tier-4 elite datacenter and easily the best in the world.

Security:
We are taking security very seriously considering how poor practices or weaknesses have been the downfall for many before us. I don't wish to go into full specifics right now, but will publish a much more detailed guide to what measures we're taking to ensure everyone's security after everything has been audited by a reputable security firm and we can use their name as a stamp of approval.
I will tell you that we'll be having regular penetration tests, anything that we don't need to know is SCrypt hashed, all sensitive data is encrypted with 2048-bit RSA public/private keys or AES256, and access to keys extremely regulated. After reviewing the threat models we also designed the system in such a way that a compromised system won't provide keys to the entire kingdom. The application server will very regularly (multiple times an hour) have audits to ensure the integrity of the files. If anything has been altered it will automatically be pulled from live. Also, the production servers won't have compilers on them.
This is all really scratching the surface of everything we're taking into consideration and doing.

My connection to Coinsetter and a little about me:
My name is Yo Sub Kwon.
I serve as an advisor to the company and I made the original tech stack decisions and built out majority of the initial design patterns. I designed the first iteration of the database, API, security, and scaling.
I've designed deployment systems to update, balance, and scale websites handling millions of users in my past and I'm familiar with building high performance web applications.
I currently work for a cyber-security startup called LaunchKey where our primary focus is private, secure authentication.

My connection to Bitcoins:
I was the one originally hosting and sponsoring britcoin.co.uk with Amir Taaki which later turned into Intersango.
I donated over $2000 to the libbitcoin project to move forward its development from my personal finances.
I was a sponsor of Bitcoin Conference London 2012 (Shirtsbyme)
Although I have very few posts, I've also been a member of this forum since Dec 2010.

I'm a developer and also you should be able to see that I've had an account on here for over two years, so long time lurker.
I'm working on the coinsetter project and was original sponsor (of resources) for britcoin.co.uk.
Also sponsored (shirtsby.me) Bitcoin Conference 2012.
Please bump me out of newbie status ^_^

Or if you are crazy and like to write code (and if you have coded the website yourself) :

  • Install the bitcoin client on your server for create a wallet and run the daemon for make transactions.
  • Deal with Mt.Gox API (curl only with PHP, json_decode don't work) for check the current price of last trade in dollars. For example, make a CRON that will check the price and convert all prices on the website or stock the current price and convert in live products prices.
  • For payments, give an new payment address for each transaction and wait the customer pay by check how many bitcoins sent to new address and at least 1 confirmation (average, 10 minutes).
-

I do almost the same thing for my gambling website. Good luck! Grin

I think this is how I'll go about it, but it's probably better to use bitcoin chart's numbers than MTGox, right? Maybe both for a sanity check.
17  Other / Beginners & Help / Want to accept bitcoin payments on my website on: July 18, 2011, 11:38:42 PM
I have a new website: shirtsby.me that I'd like to accept bitcoin payments on. Browsing the forums I've found utilities like bitcoinpayflow which I could use to handle the actual processing, although I'm sure I'd rather handle all that myself. My main concern is fluctuation in the currency's value. I see there's a JSON-api from bitcoincharts.com with some weighted prices. Is this generally what businesses are using to calculate their exchange rates?
