1  Bitcoin / Bitcoin Discussion / m-of-n USB cold storage native in Windows Server 2008+? on: May 02, 2015, 11:54:35 PM
Convert USBs to dynamic disks with the disk manager. Convert to RAID 5 or 6 in WinServ 2008 or 2012 (anyone know a way to force Windows 7, 8, or 10 to software-manage fancier RAID configs?).

Poof - you now effectively need m of n USB disks to access your coins with minimal effort on your part (do you need to match the USB ports? Beats me!). You're welcome (I have no idea what happens if you start writing some updated wallets or keys to some USB sticks and not others, and then try to write to those others later without rebuilding). The Internet suggests you can also natively do this in some linux distros.

We're in Mason, OH (45040). Have ~2000m2 usable roof space. We consume at least 138kWh/yr and this is projected to increase at least 5% (probably closer to 15%) YoY for at least five years. Energy independence isn't a priority -- I only mention it because we wouldn't want to be producing too much electricity.

Duke offers net metering with renewables-generated electricity able to be sold back at the base price we'd buy at ($.0289/kWh). On top of the 30% federal rebate, we'd plan on taking advantage of the 10-year $.023/kWh credit as well as a .71% 20- or 25-year loan.

We currently have a massive Liebert 600T of unknown capacity (the lead-acids are all at end-of-life and basically considered dead - we don't have the UPS switched to output to our outlets, even) which I'd LOVE to see replaced with Tesla UPS units. That said, with the generous renewables-made purchase price of Duke's, I'm assuming batteries are of little use outside its actual UPS use and for load-shifting (Duke does that time-of-day irritation).

Assumptions made from researching some solutions on which I may be wrong (and would love to be corrected on!):
  • We're going to lose a lot of potential electricity in Winter months due to snow and it would be reasonable to forecast it as 50% soilage loss. Without easy access to the roof, we can't even manually clear it off and would thus need to find some kind of active heating solution of which I'm unaware.
  • Tracking systems are great for "work" efficiency, but as far as I've seen, are never cost-effective and generally break way before the panels (which is a huge deal).
  • Poly-si is a reasonable "short-term" (<25 years) solution while mono-si's long-term production output and efficiency makes it attractive in long-term forecasting - BUT mono-si may become an enormous PitA and cause massive losses during Winter months due to strings going down from some panels being partially obstructed. (maybe there's a workaround?)
  • Relatively cheap panels seem to be particularly inefficient when operating below ideal capacity, where that single efficiency % mfgs like to throw around is flat-out misleading.
  • Outside the panels, mounting solution, inverters, tie-in (do Teslas handle this?), and possibly batteries, I can get everything I need at Lowe's and/or Harbor Freight. (and Lowe's even offers some of the stuff I explicitly listed!)
  • It's almost impossible for a solar installation to be NPV- UNLESS it's professionally installed. (our department has free time, so installation is effectively free UNLESS it results in exclusion from federal tax credits, in which case the cheapest option is probably still for us to go get certified and install it ourselves)
  • Some locations require government permits??


Help appreciated. Details certainly available on request! I'm trying to snag actual electricity consumption data, but it's guesstimated for now (giant office kept quite cool in Summer). Here's a .sam going over a few different potential ways we could do this (there's a $10k cost added for mounting and misc. pieces while the additional $5k in labor is for consultations -- the 142.6kWh scenario assumes we buy a truck-load of UTRF-090s): https://www.dropbox.com/s/h65eax719s005c7/TG.sam?dl=0
3  Bitcoin / Development & Technical Discussion / Elon Musk to solve the Bitcoin bandwidth problem ~2018 w/ low-alt satellites? on: January 17, 2015, 05:24:22 AM
I'd argue Bitcoin's greatest security flaw is in full node bandwidth consumption pushing users to light clients or, far worse, online wallets, negating many security advantages baked into full-node clients. For those of us without true broadband options, syncing up to the network is almost impossible without a physical bootstrap option (which some in the community do actually offer, but which is perhaps too much to expect a new, casual user to find and use), and with ~half the world still with no connectivity options at home, it's not difficult to argue the current lack of global connectivity is significantly affecting adoption.

Satellite ISP is currently too expensive and usually too limited in bandwidth allowances to sync up to the network within a month, while ~30% of the US still doesn't have access to DSL or better (DSL itself not making a full sync particularly attractive). A large part of the issue is that the satellites are far, far, far away from houses - tens of thousands of miles. Musk's vision is to have relatively cheap and tiny satellites operating, say, 1,000 miles away from the average user, still allowing unobstructed point-to-point communications between satellites without the massive latency gain from doing so in the conventional satellite PtP configuration.

“The speed of light is 40 percent faster in the vacuum of space than it is for fiber,” Musk says. “The long-term potential is to be the primary means of long-distance Internet traffic and to serve people in sparsely populated areas.” Branson is investing in a similar solution.

4  Other / Off-topic / Will the Wii's legacy be that of the last mainstream console? on: January 11, 2015, 02:02:25 PM
While Xbox may've made news from companies executives resigning after abysmal Xbone sales (MS has managed to push out only a bit over 5M), the PS4 hasn't done too much better. Sure, Sony's sold over 3x as many units as the Xbone, but this is still just a little over a tenth of PS2 units sold, and a bit over a fifth of PS3s sold, while the PS4 is now nominally two years old.

The Wii was released in 2006 and remains the most recent console to ever sell more than 100M units (barely), never able to match the number of PSX units sold. Isn't it strange that against Moore's Law, the significant increase in population and discretionary spending, and how gaming is allegedly becoming more "mainstream" each year, consoles (both hand-held and static home units) have been fairly consistently underselling their counterparts of ~a decade ago?

Honestly, I can think of more than a few PSX and PS2 games which are far superior in my mind than the best the PS3, PS4, or Xbone have offered. Are consoles a dead market? Is there going to be a PS5 or Xbox.... Two?
5  Other / Meta / Speculation thread deletion criteria suggestion on: January 09, 2015, 07:07:33 AM
Chairman theymos, I rise to offer a motion wherein the spunkulation subforum will henceforth have threads tried against the Mom & Dick Test.

If the content of the OP can be fully responded to by:

  • My dick could be a bear market next year
  • Your mom might be worth $10,000 tomorrow if her blowjobs made up 1% (by value) of global drug market transactions
  • Prices go up and down based on supply and demand
  • (remember Kronos.io? That's probably why not.)
  • (infowars link confirming OP's theory that current BTC price trend is part of geopolitical conflict between East and West)

it should be deleted. I yield the rest of my time for debate. Thank you.
6  Bitcoin / Legal / Asset forfeiture and bitcoin (US) on: December 31, 2014, 07:39:00 PM
Bill buys all his bitcoin from a large mining farm nearby from a guy he knows (Ned), who is neither a registered money transmitter nor does he even bother to record the transactions.

A law enforcement agency (LEA) with assset forfeiture powers are made aware of the transactions and, in one way or another, records a few transactions occurring. The LEA determines Bill's entire stash of bitcoin was obtained illegally, as well as Ned's USD. Ned deposits his cash at the bank, so that's gone, but what about Bill's bitcoin? Let's say Bill keeps his coin on a hot wallet on his PC and does not use any obfuscation to enter his password in, or perhaps he keeps the password in a "password journal" next to his PC. What would be the best way for the LEA to proceed in seizing Bill's bitcoin while acting in an arguably legal manner without giving Bill a chance to move the coins to a secure cold wallet (assume seizing his PC and other electronics in the house aren't enough to stop Bill)? I'm mostly curious about how the timing of this operation on the LEA's side would work out.

Let's say the LEA eventually drops the case against Bill and Ned (because the LEOs are feeling generous, and Bill and Ned seem too White to be in prison, anyway), but do not drop the case against their property.

Bonus question: does Bill have any chance of recovering the coins if he does not have a paper trail showing purchases came from money transmitters using USD for which he is able provide credible and legitimate sourcing from?
7  Other / Politics & Society / Wait.... what's wrong with "Obamacare"? on: November 19, 2014, 01:40:41 PM
I'm kind of confused on all the fuss over Obamacare. It doesn't appear to affect me or most other people living in the US except the government now endorses a wide range of private firms and advertises them on it's healthcare.gov site.

Before, I had a wide range of insurance options, but health insurance for my family would cost >20% of my monthly income, so fuck it.

Today, I have a wide range of insurance options, but health insurance for my family would cost >20% of my monthly income, so fuck it. (I'm not subject to the individual mandate fees because insurance would cost far more than "allowed" in applying the fee)


The only difference now is that people with high incomes and/or no children are now subject to an annual fee (the IRS claims they'll enforce this by withholding income tax redunds, but most people subject to the mandate fees aren't going to be getting a refund, so...) if they don't buy a particular financial service the government mandates. I don't understand the fuss over this... is there some beloved insurance company not being included on the government's health insurance Craigslist, or....?

I mean, yeah, I guess I can understand being offended that the government claims it has a right to do "this," but "this" doesn't appear to be anything significant. I'm working 40h/wk @ ~40% over minimum wage per hour, and shitty health insurance is still completely out of reach because.... well, I don't even know... because it's worth preserving the life of one person with a terminal illness for two years vs. extending the life of 1,000 people by two years each?
8  Economy / Goods / [Interest Probe] Bulk dry ice, pellets & blocks (US/CAN) on: November 07, 2014, 10:36:06 PM
I recently started work for a major dry ice company primarily supplying the MidWest, Central South, and East coast of the US, as well as parts of Canada (however, shipping can be done outside this range). Knowing some businesses are looking to "complete the circle" and purchase their supplies with BTC, I thought this could be of some interest, particularly for our meat industry (Omaha Steaks is currently the largest purchaser) and'd love to be able to put together a compelling set of documents for corporate with a list of real companies which'd be interested in making purchases in BTC. Our dry ice pellets also make an excellent, environmentally-friendly cleaner for heavy-duty objects using dry ice blasting, particularly in knocking oxidation and any other unpleasantness off pipes and metal connections quickly and with far superior results to air or water blasting, and being much cleaner than many conventional harder blasting methods (and unlike most traditional hard blasting methods, dry ice blasting can be done inside the factory).

Dry ice shipped is considered food grade and is generally in a purity range of 99.95-99.98%. All of our containers are thoroughly cleaned and sanitized each time they're returned (and they're sometimes returned with the most bizarre stuff inside, from doritos to whiskey to gold bracelets) with strict quality control measures in place on the line.

Dry ice typically costs <$1/lb, with less-processed types generally being cheapest (list of cuts for producers, list of cuts for consumers). For large orders in our operating range, CCPI can use its own trucks to ship directly to you and minimize shipping costs.

Some side-notes: I'd suggest trying to get poly-sealed or naked blocks if you can -- Kraft bagging is a nightmare and it's difficult to determine if the ice broke during wrapping or packing, while they'll all stick together once packaged (in which case, you'd probably be better off with a naked block). The airport cuts are cheap (they're reformed from scraps), but tend to be more ugly/deformed/non-whole and have unappealing bagging. High-density ice is generally a good option, though they probably won't tell you about it unless you ask -- they tend to be fully intact more often (and prettier in general) and you can use less to cool more for longer, saving on shipping.

10  Other / Off-topic / Give me your money, again, for an automated grocery store on: October 20, 2014, 07:04:09 AM
I see this as a bit of a pipe dream, but I know it's in demand in at least three nearby towns. We have no grocery stores. We have a Dollar General (carrying a limited selection of way overpriced dairy, juice, and pre-packaged frozen foods) and that's it. Some towns don't even have that, because the towns can't support them. Because of this, residents have to drive 15-45 minutes out of their way just to pick up basic staples. We can still have good margins, but not obscene margins, by being practically the only grocer in town.

This thread was prompted by a discussion here, but it's something I've been kicking around for a while. I haven't wanted to get carried away with it, though, and I don't plan to, now, so consider this an interest probe, not any kind of prospectus.

The basic idea for the store is to have an automated warehouse which serves requested goods at an automated service window. Customers do not order food at the store, but online, which works like any ordinary web-store except that it doesn't ship anything out -- it's all held at the physical location for the users to pick up. They can order at home on their laptop or PC, or at work on their smartphone. They can pre-pay using bitcoin, or they can pay at the time they pick the food up by typing in their order number and using a debit or credit card (with low margins, we scrape back costs of this by passing processing fees onto the consumer, incidentally giving them incentive to adopt BTC even if they've never heard of it). EBT payment can be worked in, but there aren't too many people around here using that -- most are factory workers, with the rest either working at the university a town over or the hospital in a different town over.

Customers can pull their car up to the service window, making this a much less painful process than going to a grocery store. Once they either verify their BTC payment (by using their BT-capable smartphone to sign a message with the address they paid with) or pay for their order using CC/debit, the service window opens up, goods start to be placed in paper bags, and packed bags are then moved out to the window where the customer loads it into their car. A customer should be able to buy their weekly groceries within around 30 minutes from start to finish if they live nearby, much better than 2 hours it normally takes with distant stores and walking around. Possibly moreover, customers will no longer feel guilty for buying pre-packaged, processed foods in bulk. For those line workers with a frozen-pizza-a-night diet - no problem.

I don't think it'd be cost-effective to truly, fully automate this. Someone does need to stock the warehouse, respond to problems, monitor the warehouse, man a customer call button, and remove any inventory which's gone bad. Almost everything requiring a human can be done from a central commercial or even residential location, from adding items to customers' orders on-the-fly, to providing extra bags, to discounting food nearing its sell-by date. What this means is virtually no overhead outside electricity, Internet connectivity, and property taxes. Most importantly - without customers or employees needing to walk around inside the store, far more space can be devoted to products rather than humans without needing to heat or cool for their comfort, only for what products need.


What I can provide:
*Building physical conveyor, bagging, and shelving system using second-hand parts (family friend would be willing to help me with this at minimal charge)
*Creating the driveway (paving it would be a dumb expense, IMO)
*Programming everything (conveyor system, bagging scripts, customer interfaces, online storefront) EXCEPT payment processing
*Monitoring, maintenance, customer service (this may include creating orders for people who didn't pre-order for particularly stubborn people)
*Store card scheme

What would be needed which I can't provide:
*Building the actual warehouse and service window (a family friend would be willing to do this cheaply and possibly finance a good portion of it)
*Suitable land
*Establishing purchase orders and logistics for non-local food
*ID scanning software/hardware
*Related payment processing software and hardware
*Enough money


Upfront costs would include:
Physical store ($125-150k, 10,000sqft metal building w/service window and extra-large signage)
Land ($45-70k for two acres on main town road near I-94)
Initial inventory ($40-60k)
Physical components for conveyors, shelving, freezing ($20-30k)
Coding (free, ideally, but I might need up to $10k worth of help, up to $50k to finish within a year)
Physical payment & interface components ($1-2k)
Misc - bags, cards, hosting, advertising, small rocks (~$700)
Licensing & registration (~$300, including 24/7 liquor)

Total upfront: ~$212-363k (I believe it likely to be around $260k)

Ongoing costs (by month):
Inventory (Huh ~$200-500k)
Property taxes (~$350)
Heating/cooling (~$250)
Electricity (~$100)
Advertising (~$100)
Machine maintenance (~$75)
Internet connectivity (~$60)
Licensing upkeep (~$25)
Quarterly accounting (investment partner?)
Purchasing & Logistics (I can handle with training, otherwise investment partner?)

Total ongoing: $960/mo excl. inventory, $201-501k with.

Assume the store receives 900 "exclusive" regulars who buy all groceries at the store and spend $400/mo on groceries, liquor, and cigarettes. This assumes nearly the entire town uses the store, and given their only alternative is Dollar General, I think this is a fair assumption. Assume there are 500 non-exclusives who spend $100/mo at the store on average. This'd come to a monthly turnover of $410k. -But let's halve that to ensure we're being realistic, and say $205k.


Assume 50% of store items (non-perishable canned & otherwise non-perishable or frozen foods) are marked up 30% of wholesale. Assume 30% of stock is purchased each week.

Assume 25% of store items (non-food, non-perishable) are marked up 25% of wholesale. Assume 50% of stock is purchased each week.

Assume 10% of store items ("cheap meat"; swiss & stew beef) are marked up 100% of wholesale. Assume 15%/mo is not sold near expiration, thus frozen and sold at 10% mark-up over wholesale. Assume 10% of that is either not fit some time after freezing or is not fit to be sold prior to freezing. Assume 60% of stock is purchased each week.

Assume 10% of store items (fresh produce) are marked up 60% of wholesale. Assume 25%/mo is not sold near expiration, thus frozen and sold at 25% mark-up over wholesale. Assume 10% of that is either not fit some time after freezing or is not fit to be sold prior to freezing. Assume 50% of stock is purchased each week.

Assume 5% of store items (premium meat cuts) are marked up 30% of wholesale. Assume 25%/mo is not sold near expiration, thus frozen and sold at 5% mark-up. Assume 10% of that is either not fit some time after freezing or is not fit to be sold prior to freezing. Assume 50% of stock is purchased each week.

Assume 10% of all non-perishable goods (5% food, 5% non-food, nominally) are on clearance at any given time for 5% over wholesale and that their sales are doubled during this time. Assume 75% of stock is purchased each week.



Whew. Alright. We're assuming $205k in sales each month, so now I need to weight the terribly broad product categories...
Non-perishable or frozen food - 1.2 units sold per month per initial stock, 60/164 of total ($75k)
Non-food - 2 units sold per month per initial stock, 50/164 of total ($62.5k)
"Cheap meat" - 2.4 units sold per month per initial stock, 24/164 of total ($30k)
Fresh produce - 2 units sold per month per initial stock, 20/164 of total ($25k)
"Premium meat" - 2 units sold per month per initial stock, 10/164 of total ($12.5k)

So now for some shaky math to project monthly profits from product categories...
Non-perishable or frozen food - $75k/mo sales, $375/mo gross from clearance items, $20,250/mo gross from non-clearance items, $20,625/mo total gross.
Non-food - $62.5k/mo sales, $312.5/mo gross from clearance items, $14,063/mo gross from non-clearance items, $14,375/mo total gross.
"Cheap meat" - $30k/mo sales, $450/mo lost to spoilage (don't worry, I'll eat it!), $405 gross from frozen products, $12,750/mo gross from normal products, $12,705/mo total gross
Fresh produce - $25k/mo sales, $625/mo lost to spoilage (om nom nom), $281.25/mo gross from frozen products, $5,625/mo gross from normal products, $5281.25/mo total gross
"Premium meat" - $12,500/mo sales, $312.50/mo lost to spoilage ("welcome to the neighborhood" expired meat BBQ. Rare? No problem!), $140.63/mo gross from frozen products, $2,812.5/mo gross from normal products, $2640.63/mo total gross

WHEW! This really needed a spreadsheet... I guess I got carried away. Anyway- so we can a project $56,015.63 gross per $205k in sales. -And guess what? NO SALARIES! That's basically all realizable profit, and once DG's pushed out of town (easy peasy), we're the only player! Not much point in even going over overhead, but for the sake of being complete after going this far, actual net/mo would be ~$55k. -On a ~$200-360k upfront investment. Crazy, right? Sounds crazy. What'd I screw up? Cheesy
11  Economy / Service Announcements / [Kluge] Escrow offered to public again (BTC, LTC, DOGE +requests) on: October 16, 2014, 09:00:40 AM
Whether for business or regular p2p transactions, there are no fees so long as the transaction value is equal to or greater than BTC.1 (in which case, I'd like a pre-paid BTC.01 tip). Tips are appreciated but neither required or expected. Escrow is not provided by any establishment, service is guaranteed by nobody, and funds are not insured. However, I have a long history on this forum and in providing escrow, with over BTC1.3k in public transactions held to date.

Arbitration in case of dispute is provided freely but is non-binding. I'll suggest what should happen, but will not necessarily enforce it. If either party disagrees with what I suggest, they're welcome to either renegotiate between themselves or go to a proper arbitrator or court to hash it out in a more formal setting. I'll continue holding funds until a binding decision is made. The only time funds may be sent without permission by both parties is when one party logs a dispute where they've upheld their end of the bargain and the other party is non-responsive for at least 14 days from the time the dispute is logged and I contact them or in extreme cases where I have absolutely no doubt the other party would win in court and that the ruling would be just.

What is escrow?
Escrow agents hold funds until certain conditions, defined and agreed to by the buyer and seller, are met. Escrow is used to ensure the buyer has the funds to pay and the seller sends the goods or renders the service as described. Escrow is most commonly used in the US for real estate, but is also used with some online stores (PayPal, for instance, acts as a kind of escrow provider) and in informal gambling.


What's included?
Coin control. When coins are sent to an escrow address, they stay in that address until funds are released or refunded. You can always check Blockchain to ensure your funds are where they sent them, safe and sound.

Pre-made forms. If you choose to use them, I can generate a form for your specific agreement (or use my default one) which covers many things you may not think of. For general users, it's recommended you use a pre-made form to prevent vague, difficult-to-enforce agreements.

Dead man switch. If I die and am survived by my partner, she has instructions on how to proceed. Specifically, she's to ask which escrow provider you'd both like your transaction transferred to, pay any applicable fees, then send the coin and original contract to the new provider.

Attention to detail in dispute resolution. See previous non-binding ruling here. In other cases, I've emailed and called various companies to ensure stories check out, whether they speak English, Mandarin, or Swedish. I recognize both the financial and reputation-related harm which'd come to me if I made an inappropriate ruling.

Available on request
Multisig. Provided through Casascius' Bitcoin Address Utility, multisig escrow is a little more labor-intensive for everyone involved, but provides insurance against me running off. Provided freely.

Man-in-the-Middle. I will allow items to be shipped to me for inspection and testing (if hardware) prior to shipping to the buyer. This strongly protects the seller from a buyer claiming he didn't receive what was advertised or that it was DoA. This is often cost-prohibitive as I require my shipping costs to be pre-paid along with an extra mandatory fee of $15 equivalent in crypto or cash for my time.

PGP-encrypted communications. Available at request and free. I do not handle illegal goods.

Private transactions. By default, all transactions are logged in my Google spreadsheet for the sake of transparency and somewhat for advertising. If you'd prefer I not do that, just ask -- no skin off my bones. Smiley


As long as both the buyer and seller recognize risks associated with non-tangible goods (especially possibility seller can reclaim accounts), I'm now willing to accept escrow contracts for non-tangibles like domain names or MMO accounts. I will, however, refuse to handle any transaction involving pre-selling or "investments," with very few exceptions. Giveaways and bets (within reason -- no 200-person 1ksat giveaways, please!) also accepted. Currency exchanges are fine, but I will not hold online fiat (PPUSD, PerfectMoney, etc) -- cash would be okay in the strange situation where that'd make sense.

PM, email, Skype. I may take up to ~18h to respond and have a varying time I'm online. Calling is available in case of emergencies (see GoogleDoc, first link in this post).

As you can see - though fresh produce, fruits, dairy, and veggies are now priced outside the reach of the working class without food stamps, paper product prices (making the generous assumption that rolls have not decreased in size over time) have dropped. Hooray!

For our small basket of goods, the price increase (keeping in mind I was generous in estimates for 2014 quantities and conservative in estimates for 1991 quantities, and prices came from a specialty meat market while current prices come from Kroger, AND there was no advertisement for beef, which is now ~$3.19/lb) from 1991 to 2014 for groceries and staples has been ~115.93%. Nominally, this means there's been ~5.04% grocery price inflation per year over the 23-year span. -Or, using government math which hides compound inflation, ~3.4%. (for reference, USG claims 2.55% on CPI from '91-'14)

(ETA: fixed ice cream price comparison, h/t thoughtomator -- ETA3: fixed 1991 unit labels)


ETA2:
Nominal median household income in 1991: $28,479
Nominal median household income in 2013 (most recent USG data): $51,939

Median household income increase: 82.38%
Guesstimated grocery bill increase: 115.93%

Grocery price increases have outstripped household income increases by ~40.73%
13  Economy / Gambling / What prevents casino "pre-rolling"? on: September 29, 2014, 11:50:05 AM
Let's say you win on >90 out of 100.

What prevents the server from quietly pre-rolling with the client's self-generated seed and then re-rolling if the number's ever >90? -So it just dumps "bad rolls" and regenerates until the results favor the casino.

Would users ever notice they're generating and sending multiple hashes even though the casino site's only showing the hashes for the roll which generated a <=90?
14  Bitcoin / Mining speculation / As some of us enter Winter, here're some calculations on true cost of mining on: September 15, 2014, 03:27:16 AM
gallon of natural gas has ~84,000 BTUs in it.
gallon of propane has ~91,500 BTUs in it.

... in case anyone was wanting to calculate the relative cost assuming heat's desired since some of us are heading into Winter.

Using my own #s for example:
Our house uses ~50MBTU/year for heat.
Electricity cost = $.145/KWh
1Wh=~3.4121BTUs
Propane cost (we buy in Summer, and holy Hell have prices risen) = $2.492/gal
Natural gas unavailable

For propane, I'd need ~546.45 gallons. Assuming 20% of heat is lost by heating rooms we have no reason to heat (closed ducts as well as ductwork and heater in basement [no purpose in heating basement with all its windows] all still leak significant amount of heat), this becomes 655.74 gallons. @$2.492/gal, that's $1,634.10/year to heat house.

For electric, I'd need 14,653.73KWh. Since I can strategically place miners, there is no wasted heat. My cost is $2124.79/year.

If we bought propane in Winter, of course, cost of electric vs. propane would be much, much closer (and electric would've been cheaper this last Winter). However, with these numbers, I simply need to earn ~$487.69 by mining in all of the cold season, where everything after is effectively profit. Assuming the 14,653.73KWh usage needs to be spread out over 140 days, this means I need to consume ~104.67KWh/day, or ~4.36KWh/day, which means I need ~4,361W in mining equipment.

Numbers can be improved by shutting miners off while we're asleep except in bedrooms while temperature difference in cold season can be countered by over-clocking/over-volting or under-clocking/under-volting. However, I'd rather keep things under-volted and deal with it being a little bit colder inside on most days -- of course, propane can still be used on extremely cold days.
15  Other / Meta / Adblock/ABP circumvention code may be causing LastPass to spring a memory leak on: September 14, 2014, 11:54:49 PM
I've had an issue where Bitcointalk's Chrome tab would take up obscene amounts of memory. The most recent time I closed it, it neared 2GB, but this was after something like a week of the page being open on the same tab. This doesn't happen on any other page I'm aware of, but LastPass is known to have memory leak issues under certain circumstances on all browsers.

Disabling either Adblock or LastPass seems to resolve the issue, but if they're BOTH open and enabled on the page, it starts slowly growing, so my guess'd be that Adblock's modification of the pages are causing LastPass to store data it shouldn't be and not purging it, maybe due to the way BTCtalk tries to circumvent ad-blocking.

Since having Adblock or ABP enabled on this site'd be pointless, anyway, the obvious workaround is to disable AB/ABP. Fwiw.
16  Other / Off-topic / Steam Marketplace is pretty slick, great place for BTC on: September 13, 2014, 06:55:23 AM
High fees, but it'd be the ideal place for BTC option to exist. Tons of audience crossover, I'd imagine. I actually never noticed it until a few hours ago when I felt like playing a game in Steam for the first time in a long time. Ended up selling some TF2 "strange parts" garbage for ~$5 super quick and simple, but obviously, I'd prefer payout in BTC instead of having it constrained to Steam after also taking a 5-20% Valve fee hit. (otherwise, I have to sell Steam gifts for BTC, which is a pain)

Might be worth it for others to politely hassle Gabe. gaben@valvesoftware.com
17  Bitcoin / Armory / Feature request: better functionality of sendmany Txs & Tx task scheduling on: September 02, 2014, 09:21:16 AM
AFAIK, no client has fully taken advantage of the functionality permitted in sendmany transactions.

Every month, I make a $500 split BTC payment to ~30 people. They all get a static % of that $500. Every month, into an Excel sheet, I enter the BTC equiv. of $500 to determine what everyone should get, then manually extract every single address and BTC amount from that Excel sheet to paste into Armory or Core. It sucks, and by the time I've entered everything in, triple-checked, then written the details down in the email, the price has moved +-$20. I'd like to be able to save a script in Armory where I can set up percentages for each address, then enter the amount of BTC I want split between them.

My situation is probably unusual, but this could also be very useful for charities. As is, there are many "meta charities" whose job is literally to just collect funds and distribute payments to many different charities. This is largely unnecessary and should be replaced with sendmany links so people can donate to a large basket of charities with a % split they choose in the client upon clicking the URI.

Additionally, a client should permit task scripting. I should be able to set a daily, weekly, or annual time for a particular payment script to execute - with user confirmation required, of course. This last feature request has so many use cases, I don't think I need to spell them out for anyone. Smiley
18  Other / Politics & Society / Could someone provide evidence that the majority of Russians aren't insane? on: August 28, 2014, 04:56:15 PM
Keeping in mind I'm well-aware more than half the Russians on here are probably Thieves, I'm seriously interested in trying to understand Russians' surprisingly widespread support of Putin/Medvedev while the Russian government continues restricting basic human rights.

First and biggest -- Russians seemed to truly HATE Yeltsin. Chechnya was/is a disaster, the economy crashed terribly, he nearly started a full-blown civil war initiated by parliament and his vice president only ~20 years ago (after attempting to unconstitutionally dissolve parliament, presumably because Yeltsin was hammered and belligerent that day), repeatedly came out as a disreputable liar on the International scene with regards to POW statuses and human rights violations (made odd because it was Yeltsin who admitted it), and then hand-picked Putin (who later hand-picked Medvedev). Yeltsin went out with a 2-10% approval rating, but Putin's numbers are considered "low" when they go in the high 60s (lately, it flicks around between 80-90%).

Putin continues imperialist policy in Chechnya while trying to take a high moral ground in Ukraine, a long-standing policy which led to the Beslan school tragedy. In response to that tragedy, Putin waged a war against human rights and privacy, blaming everything but his anti-Chechen policies and introducing what was called the Russian PATRIOT Act. Putin has continued cracking down on journalism, freedom of speech, and privacy rights, with Russia having a tragically high amount of unresolved murders of journalists and recently forcing what any normal person would call a small blog to adhere to repeating Russian fairy tales without deviation or face prosecution.

Putin and Medvedev are "anti-corruption" publicly, but in a Snowden cable which has oddly been ignored by all media (including Western), the Russian Mafia branches were alleged by credible source to operate (and likely still do, though the Moscow mayor Luzhkov, a co-founder of Russia's ruling party, was fired) not only with a FSB/KGB wink and nudge, but armed protection.

Are Russians anti-Russian or just blindly pro-KGB? -Or maybe Russians are just so pleased with the modest post-Yeltsin economic recovery, non-economic quality of life decline is able to be ignored.
19  Economy / Gambling / How are gambling sites dealing with edge competition? on: August 28, 2014, 11:07:46 AM
Back in the early lending days, when we accepted deposits (d'oh!), we all had serious difficulty when Pirate hit the scene, which eventually collapsed every FRB scheme in the lending section. The issue largely stemmed from people offering far too high of deposit rates (without an established market, we didn't have very good ideas of default rate and just how bad Pirate's collapse was going to fuck us over, so we over-competed). In the informal lending cartel made up of the largest lenders (with the notable exceptions of OgNasty and Goat, mentioned only to be accurate), which was set up as a direct response to this even though we all (or almost all) ended up sending money to Pirate, we all came to a gentlemens' agreement to limit how much we'd pay out to depositors. The idea behind this was to ensure we didn't have to send funds we had lent to us by depositors go to Pirate or a similar scheme to be able to continue allowing deposits without losing our shirts (we all wanted to keep deposits, even though increasingly unprofitable and risky, because we have much more flexibility and opportunities open to us when we have 10kBTC in assets rather than 1000 -- this was early days, remember). We ended up having one major lender go rogue, and since the rates were absolutely nuts, many new lenders popped up with fantastic rates and were able to establish reputation quickly due to the volume they could take on from "guaranteed" ultra-high interest on loans (guaranteed until Pirate decided he was boned).

Anyway -- I was wondering if casino ops have come to a similar agreement and what the suggested response is to rogue casinos given customer loyalty and first-mover only gets you so far. It looks like there's a possibly-agreed-to house edge minimum of 1%, but there have certainly been some casino ops who push the boundaries and compete with each other, going down to ~.9%. How low will you "let" them go, or are you willing to have a dry spell of little volume to let them die by attrition? (though by nature, they aren't really at risk of that assuming very low overhead compared to volume*edge)
20  Other / Off-topic / Anyone else have recurring nightmares about the NSA and other USG bureaucrats? on: August 25, 2014, 10:32:41 PM
Little's easier to take way out of context than search history, but police still use it as legit evidence anyway, presumably hoping to play on judge/jury ignorance.

After reading a news story, I Google common methods of murder. Later, I suddenly remember the names of a few people from school and wonder what they ended up doing.

Starting two days from that point, I'm texted, every day, the names of the people I Googled, and then called immediately following the texts. This isn't effective because I never answer my phone unless I manually added the person as a contact. My wife asks about it and I explain the goofy situation with no worry because I did nothing wrong. "ooooooookay." -And we go about our day.

Then, about a week in, a particular application is regularly launched in the background every day, but is not in any scheduled tasks I can find, while no unknown programs have privileges to do something like that. I immediately stop what I'm doing and wait him out (which is probably the most bizarre way possible to handle that, though probably not as odd as having someone in the NSA literally stare at a remote screen for his entire shift, but only his shift, for activity).

-But one day I'm too curious to resist. I open the application and see "Hey, man. I got some really cool porno sites and hacking stuff at [some URL]." That's the dumbest bait I've ever seen, so I know it's those paranoid lunatics at the CIA, probably helped by the NSA, and I know my life's over because I just admitted I use the computer.


That weird illogical dream stuff: The people Googled are never murdered, so I'd assume the charges, if any brought up, would be extremely minimal if a case could even be made.
