1  Economy / Services / Toomim Brothers hosting -- Lowest prices anywhere! http://Toom.im on: August 24, 2014, 05:20:16 AM
We are offering a hosting service for rackmountable bitcoin miners. We're located in Grant County, Washington, USA, where there is a plethora of cheap hydroelectric power. Our first facility has 500 kW of power installed.

We've optimized our system for high-density rackmountable hardware. We're particularly fond of Spondoolies hardware. We do not currently accept Antminer S3s or other non-rackmountable equipment.

We'll have more information up soon. For now, just check out our website: http://toom.im.

If you are a customer of ours, feel free to post a review.
2  Economy / Services / Help us build a datacenter/warehouse in central WA on: February 15, 2014, 01:03:21 AM
Hi,

I and some friends of mine in Seattle are getting into medium-scale bitcoin mining, and are exceeding the electrical capacity of our available house and office spaces. We are interested in setting up a warehouse or low-grade datacenter in central WA, maybe in Wenatchee or Quincy, in order to take advantage of the < $0.03/kWh hydro electricity and cheap rents. However, we're concerned that the distance from any of us (2.5 hours driving) combined with our day jobs could make maintenance and installation a nightmare in terms of how much of our time it would take to do so. So we thought we would look for help.

I see a few possible ways in which someone could help us:

1. We could rent a house for the miners and give someone free housing in exchange for providing security and some basic technical assistance keeping the miners running.

2. We could hire someone who lives nearby to help us when minor miner problems arise in the space (like a miner needing to be rebooted) and/or to help with larger installation projects, especially when the mountain passes are snowed in or we're out of town

3. We could collaborate with another bitcoin mining operation in the area to share space, labor, and maintenance costs in order to get a greater economy of scale and less labor per miner.

What we're not particularly interested in is people who want to piggyback their mining equipment on our labor. We currently have better access to capital than to space and labor, so we're not interested in arrangements that involve us doing more work than we would do if we worked alone.

Let me know if anyone thinks they might have a fit.
3  Economy / Scam Accusations / TehoM attempted a Bitrated email spear-phishing scam on: January 20, 2014, 05:47:27 AM
https://bitcointalk.org/index.php?topic=419491.0

This thread was cleaned and locked by TehoM. It was an offer for a sale of a November Jupiter from Australia.

Early on, he asked to hurry, since he claimed to need to leave in 30 minutes, and also claimed to have another buyer trying to buy. This struck an alarm bell, since scammers like to make people think they're rushed so that they spend more time sending money and less time thinking about things. But I humored him. The seller offered to do escrow with Bitrated, and allowed me to choose the arbitrator, and wrote the Terms of Agreement himself. After I agreed to his wording of the terms of agreement to him over email, I got this message from "transactions@bitrated.com":

I noticed the difference between 7.5 BTC and 8 BTC in that email, and asked him if he would be okay with 7.5 BTC. He said 7.5 BTC would be fine. (WTF?) I also noticed that I had no proof that the email was really from Bitrated, and that that address could be anything, so I logged into bitrated and tried to create a transaction myself, and noticed that it didn't send any emails or even ask for an email address. So I didn't give him anything, and called him on his BS. He then stopped answering messages.

DO NOT send money to any address listed in an email purporting to be from Bitrated or any other agency. Emails are not secure and are easy to spoof.
4  Economy / Computer hardware / [WTB] KNCMiner Mercury, Saturn, or control board (USA) on: December 15, 2013, 03:20:01 AM
I'd like to buy a Mercury for 3.9 BTC or a Saturn for 7.5 BTC. I'm in the west USA (Seattle and San Francisco), and I can fly over to pick it up if you're not too far away. My estimate is that a Mercury has 3.6 BTC of revenue left in it, and a Saturn about 7.2 BTC, so I'm not trying to make a profit with this purchase; merely trying to fix a broken miner. I fried my October Jupiter's control board. I'm trying to replace it, and KNCMiner is a bit slow on the RMA, so I'd rather not wait for them.
5  Economy / Computer hardware / [WTB] KNCMiner Jupiters and/or Saturns in west USA on: December 01, 2013, 02:32:39 AM
I'm looking to buy some KNCMiner equipment. I'm mostly interested in October and November Jupiters, but I could go for a Saturn too if the price is right. If you're in the western USA, I'll probably fly over and pick up (and pay for) the miner(s) in person. Bonus points if you're in Seattle or San Francisco.

I'd like to spend about 10 to 14 BTC per Jupiter. Saturns, half that. Exact price depends on whether you have it in hand or if it's still in the mail from KNCMiner, where you're located, whether it's a Oct or Nov miner, your reputation/trading history, and escrow arrangements. I'm interested in buying 0.5 to 4 TH/s total, depending on prices.

If you have other mining equipment for sale (at least 30 GH/s), feel free to send me offers. I expect to be willing to pay between 0.013 and 0.024 BTC/(GH/s).

Scammers, don't waste your (and my) time. I will see through you, and I will not agree to any mail-based trades without escrow and proof of possession.
6  Other / MultiBit / MultiBit and address reuse on: November 30, 2013, 11:23:02 AM
I've made a few transactions with MultiBit, and I'm pretty happy with it overall. However, I've observed that it tends to accumulate bitcoin in one address, which it reuses over and over again. For privacy and anonymity, I would prefer it if MultiBit created a new address to use to receive the change from each transaction instead of reusing one and making it easy for the IRS and ex-girlfriends to stalk my every financial move. Does anybody know anything about this? Was this behavior the result of a conscious decision? Is there any compelling reason for the address reuse that I don't know about?

To illustrate this issue, let's say I have 3 addresses (A, B, and C) initially, each with a different amount of coins:

A: 1.0 BTC
B: 1.5 BTC
C: 2.0 BTC

Let's say I want to send 2.1 BTC to address X. When I do this in Multibit, the transaction it generates ends up looking something like this:

Inputs:
A: 1.0 BTC
B: 1.5 BTC
Outputs:
X: 2.1 BTC
A: 0.3999 BTC
Fees:
0.0001 BTC

I would prefer that MultiBit instead created an address D for the change. Why doesn't it?

(I'm not sure if it would prefer address C or A as the change output address. I haven't observed any trades that would disambiguate yet.)
