Right now - Association, "Never My Love" - but my playlist has a fairly wide range of music on it. Almost no country, though (and what little I like tends to be old CLASSIC country, Sun Records era Cash for example), and I'm one of those that believe that the "c" in rap is silent.

 Where is Ranma 1/2?

 Where is Rurori Kenshin?


 Of the short list in your poll, the only one I've ever seen is Cowboy Bebop (fairly good, not great) and have heard of 1 or 2 of the others.

Price $2750 With Free Shipping To The Lower 48
Edit- NEW PRICE 6.5BTC

Let me know if this price is fair, as I hardly ever see these selling on ebay or here.


Thanks!

 MAT labeled/branded version of the Alcheminer, the last of the NEW Alcheminers from the original manufacturer were being sold direct for $999 + shipping 2-3 months back.
 As far as I have been able to determine, the only change was the badging on the case and that MAT never made updated firmware available.

That sound troublesome. These second hands are from Batch 7, it makes me wonder what bugs i'm going to get. =/


 From my experience, no new bugs compared to Batch 5 - these appear to BE late Batch 5 units that Bitmain went mining with themselves for a short while.

Depends what alt-coin you want to mine. At the moment, Litecoin and Dogecoin, right now, not profitable without a newer AMD GPU. So, in short, nope.

 NO Scrypt coin has been GPU mineable for a profit for ballpark a year and a half even WITH cheap electric. Gridseed didn't quite manage to kill that idea, but they made it very difficult then the competition arrived and killed the idea.

 Forget anything SHA-256 based like Bitcoin, those haven't been GPU mineable for years at a profit.

 X11 and other later algorythm based coins can be, if you optimise the setup for them - right now the NVidea Maxwell boards like the GTX750, GTX960/970/980 seem to be optimum for those type coins but do your research first, things CHANGE.


 You also need fairly low cost of electric even on those altcoins that CAN be mined profitably.


 I don't know offhand of any coin that can be profitably mined with CPUs, but some of the really new stuff might be.

I suspect photoshop at work - the specs match pretty well with a 16 BM1384 per chain unit, and the photoshop appears to have 3 PCI-E connectors per board (if this monster actually existed you COULD use multiple power supplies, no need for a 230V circuit), but I suspect it's not an actual design.

 Would have been better to photoshop a 20-per-chain design, much better efficiency at the cost of some hashrate.
 Even 18-per-chain would be a significant efficiency gain, though iffy if it would still be profitable after next summer and block reward halfing.

 

 Oddly enough, one shelf of my S5s are set up side-by-side with the pair of power supplies on one end of the shelf (cord length limit to the outlets) which has a superficial resemblence to this monster.

I don't see them making a rack-mount miner from the chips to be used in the S7 and calling it an S6.

It's SUPPOSED to be user-adjustable, but the "user adjust" part of the website has never worked for me. I've tried to adjust it a couple times, and it just ignores me.

 Could be an error on my part, I suppose, but it seems straightforward.

 Not really a big deal as far as I'm concerned though, given my payout has tended to be a lot higher than I would set it anyway by the time the pool has been catching up enough to give me a payout. Seems to be a run of poor luck since I started mining via them on finding blocks, but the bitcoin mined DOES show up reliably in time.

To get back on topic. How is bitcoin better? It has a bigger user base and that's about it.


 Bitcoin is better at this time due to acceptance. This might be in part due to the larger user base, but I'm more inclined to say that the MUCH larger user base of Bitcoin is due to it's widespread acceptance compared to all other cryptocoins combined.

It's perfectly fine within the Bitcoin protocol to create, sign and broadcast a new transaction, using output from an earlier transaction that was just pushed before, and has not been confirmed yet.


 Interesting in theory, but try DOING that with an actual Bitcoin client. I've yet to see one that will let you spend Bitcoin from unconfirmed transactions, and IME they generally require multiple confirmations before they allow you to then move that Bitcoin on down the line.
 It's a GOOD thing actually, as a security measure.

And "commonly an hour or two" is even more bollocks.


 Nope, it's experience. I do grant that it's less likely to take that long on Lightcoin.

And yes, obviously, there is no such thing as chargebacks with cryptocoins. I mean the concept of a transaction becoming irreversible, or permanent, or set in stone. With Bitcoin, theoretically, a transaction is not 'guaranteed' (although *extremely* unlikely to be nullified) until it's confirmed. With paypal or credit card it can be reversed (and happens quite often) until the chargeback/dispute period expires, and that's typically 3-6 months.

 Which is different from a chargeback. On a chargeback, the transaction WAS confirmed, then later the CC issuer was told to reverse it due to some reason - non-delivery of goods or fraud being probably the most common issues leading to a chargeback.

The consequences of using scrypt mean that there has not been as much of an 'arms race' in litecoin (and other scrypt currencies), because there is (so far) no ASIC technology available for this algorithm. However, this is soon to change, thanks to companies like Alpha Technologies, which is now taking preorders.


 Alpha Technology has been "taking preorders" for a very long time - and still has yet to deliver anything. Not sure if they count actively as a scam at this point, but all the available evidence is pointing that way, though it's possible they were underfunded and just couldn't deliver.

 
 The real, abet fairly small, Scrypt arms race has been between Gridseed (now part of SFARDS), Innosilicon (Their A2 Terminator and various spinoff designs), KnC (the Titan DID eventually ship, with very high performance and junk reliability, and a subsequent withdrawl from ALL retail selling or any further interest in Scrypt), Alcheminer (which has since sold out with no indication they are going to bother with a new generation product), Zeus (dead), Silverfish (also appears to be dead), and I think I might be forgetting one.

 The ONLY folks that have done a "second generation" of Scrypt chips to date are SFARDS and the "announced" Innosilicon A4.


 Compare to the dozens of Bitcoin ASIC chips to date, and at least 5 current companies with a "new generation chip", often in the 3'd 4'th or even 5'th generation from that company, announced or delivered in 2015 alone (Sfards has released, BitMain has announced "soon", Innosilicon has announced tapeout, KnC has announced deployment, BitFury appears to be deploying but only sells to large farm groups now) - and some question as to how many OTHERS with track records are working quietly on "new generation" products with no announcement yet like Avalon.
6772  Bitcoin / Mining speculation / Re: What is your electricity price on: August 07, 2015, 06:55:32 PM
Is that 0.023 your final rate all up, or your base rate?




I have a couple small surcharges but those add up to maybe 50 bucks.

 How much power are you using to count $50 as "small surcharges"?

Minimum withdrawl isn't really applicable to how Elgius works, though there is a minimum (.04 BTC appx.) to get put into the payout que that kinda might sorta count as a minimum withdrawl limitation.

5 units sfards miner already arrive in our farm, but the quality is not as good as they promise, only 1 of them run at 1.5T/48M, all other four canot farm at promised hashrate, 2 of them canot run at all, ask other friend got similar report.  already ask sfards technician to provide help, but i think it is better to wait until the quality become more stable, it will be a nightmare for our employee if a large batch of miner canot run stable

 Looks like they DIDN'T get any board-level design competance out of the merger with WiiBox.
 They had the same sort of garbage quality issues when they initially released the "orbs", and the design work on their "blades" was just total garbage.

They're skipping a RACK MOUNT generation, to be picky.

On the S5, you need the cooling air flowing across the back to cool the parts that are on the back side of the circuit board.

I've got 3 that are usually 2-3 degrees apart, then the 2 new ones are more like 8 degrees apart. That seems a bit excessive.

 I might break down this weekend and try redoing thermal compound on the 2 boards that are reading way higher than the other 2 in the same machines.



 I DO wish they'd put temp sensors on the chips like Spondoolies did on the Rockerbox chips (SP20E etc.).

Both  of these "used" S5s are running a bit odd - the "bottom of status screen" hash board runs 6-8 degrees cooler than the other of the same unit or than any of the other hash boards in ANY of my S5s when running at the same clock speed, the "top" board is kinda mid-range on temp compared to the boards in all my other S5s.
 Temps are running about the same on the S5 with the straight-blade heatsinks and the one with the older-style curved ones and they're both meeting specs easily though, once I got a couple configuration quibbles fixed (MY glitches, not theirs).


 I got a call from FEDEX the day after they shipped about some sort of customs issue, but they apparently resolved it before I noticed the call - by the time I noticed I HAD a voicemail about the issue asking me to call them back, tracking on their web site showed that the units were already in Indianapolis (I think they have a major hub there, for similar reasons to why UPS put THEIR primary air shipping hub at Weir Cook / Indianapolis International a couple decades back).
6779  Bitcoin / Mining speculation / Re: Antminer S6 speculation on: August 06, 2015, 08:38:53 PM
Given that their "Ares Scrypt miner" is obviously an Alcheminer at a ridiculously high price, I have some doubts about this Uranus thing - though to be fair, they do specify somewhere on their page

In production we use our US partner developed ASIC chips and motherboards produced by us



 The BIG sticking point is that "20 nm" part of their spec - I've not seen ANYONE from an ASIC company claiming to be working with a 20nm process.

 They also say the CHIP efficiency is .24w/GH, the MACHINE efficiency is .26w/GH, yet the machine is "designed to be underclocked" - voltage converters for typical low-voltage applications like SHA256 ASIC do NOT achieve a well over 90% efficiency, and there seems to be ZERO allowance in those specs for the power consumed by the controler board and other parts needed for the ASIC to talk to the outside world.


 Definitely a "I want to at least see a review from a few REPUTABLE sources" item before I will believe it's real.

Just got my pair of the used S5s - one of them has STRAIGHT BLADE heatsinks in it, the other the usual curved.

 I wonder it Bitmain finally gave up on that curved sillyness....


 Both of them were pretty clean, the shipment packaging was a little marginal but it worked, a couple of the HS blades were bent up on the bottom but that's pretty common and easy to fix....
