No the pi is just a tiny computer.

And the 51% attack is based on miners, not nodes. Whether someone accepts your transaction is based on how their node is configured.

A standard pebtium laptop would take a week or two to download the blockchain (they aren't very fast).

If you can get better ram for it then you might be able to get it to go a bit faster.

There was a thread of people using raspberry pis which use about the same amount of electricity as some modems (afaik). See if you can find power ratings for the products you want to buy to see if its worth it. You don't get paid for hosting one anyway so it might or might not be worth doing it. You'll be propagating the network but there are a lot of nodes running already.

It'd certainly be difficult to achieve, and I imagine bitmain and slush and a few others probabky connect to themselves via vpns or aws instances in other countries so it'd make it very hard to. Omit someone's block.

Block explorers also seem pretty well connected to the blockchain so you'd have to incentivise them to ignore the block too. And then there's privately owned nodes that will probably still accept the blocks and other miners would still accept each others blocks so short of a 51% hashpower attack, I don't think there's a chance for this to happen.

Ck is right about it taking 200ms as a max to broadcast data. My old laptop was still getting ping speeds of 8ms to the nearest node and 160 to the farthest (when connected to Cool.

In addition to my last post, it might be worth sending aessage to coinbase support too. They might just have a bug since lbc uses native segwit addresses and if they did send it, they now have a bug...
4725  Bitcoin / Bitcoin Technical Support / Re: Sent bitcoin cash to a bitcoin address using (Coinbase to Localbitcoin) on: February 06, 2020, 01:30:22 PM
You'll have to email local bitcoins support and tell them you sent bitcoin cash to that address...

If they tell you its impossible for them to recover it, then they're jut outright lying... They may not want to recover it but you might be able to keep emailing them to a point where they do (they'll have engineers at least to be able to do it).

My tetley is 3 kcal also per bag Grin
That's only if you eat the whole bag and all of its contents, right?


No, it's 1kcal per 100ml of "infusion". PG tips were 4kj afaik (4/7kcal).



The corn flakes just gives me an excuse to buy the cheap stuff from lidl then, that's a win win 🤣 (they're not as tasty but they are 96% maize and still are pretty good with milk).

And I'm not sure how accurate they have to be with their values but I assume it's still the 95% purity on most things (in terms of iron content).



@hammasan yeah I think that sort of advertising here has been banned for a while and that was almost definitely the reason...



I thought the general rule of thumb was that 90% of the nutrients are taken in an 10% are left to turn into shit... Its why animals don't like to eat human dung and why humans don't eat each others (well its one of the reasons anyway).

Yeah I can't find any other source here. Apparently universities are turning down opportunities to research it for fear of being labelled politically incorrect. Or somethin glike that.
4728  Other / Ivory Tower / Re: I need help understanding what trans people feel.... on: February 05, 2020, 04:57:46 PM
I'm after finding where your 40% figure came from.


Although maybe you've just plucked it from thin air now and assigned it to that.
4729  Other / Ivory Tower / Re: I need help understanding what trans people feel.... on: February 05, 2020, 04:50:42 PM
So provide your own from a legitimate source?

Tbf, it's hard to work out what's fact and what's fiction:

Quote
the greatest flaws in medical literature about gender reassignment were in those studies unsympathetic to transsexual people. For example, one study was based on a survey of seven transsexual prostitutes interviewed in one gay bar in Chicago.
https://www.theguardian.com/society/2004/jul/30/health.mentalhealth

(the guardian are fairly left leaning, more left than I am but still seem to not be too far gone as to be overly biased)...

Quote
Research from the US and Holland suggests that up to a fifth of patients regret changing sex. A 1998 review by the Research and Development Directorate of the NHS Executive found attempted suicide rates of up to 18% noted in some medical studies of gender reassignment.

Unless you're a friend or know them well, you should probably meet them with indifference towards it. Much like how you'd be indifferent to hair colour, eye colour...

It's up to their friends and surgeons to decide whether they're of sound mind to make their own decisions. The only thing I can think of as being similar is someone with a physical disability being offered a cure when they're 20, would you take it or not? It'd often depend on the person. I'm pretty sure things as simple as having an extra toe are considered a disability of sorts too so... [it's obviously a lot different but I couldn't think of anything].
4732  Other / Politics & Society / Re: Can supplements be bad for you? on: February 05, 2020, 02:32:56 PM
Since you took iron as an example, 100g of corn flakes contain 53% of your RDI.

I'd dismiss RDI on being 100% fact as I don't think some of it is reasonable. (we were looking at lethal doses for chemicals and calcium becomes deadly at 1000g - apparently). I imagine that's my entire evening meal in calcium which would be very unreasonable and thus a useless piece of data (I'm sure you'd die before then anyway).



My table salt contains sodium chloride and sodium amide (there's something before the amide but I opened the container upside down ).



Not going to argue with the meat and two veg but it's a little wrong.
What no one will mention from the UK is that you need a nice thick gravy or apple sauce and you'll also need something to soak it up when you're done. And the meat and two veg also assumes the main event be potatoes (a selection of roast, mash and potentially wedges too)...

4733  Bitcoin / Electrum / Re: Electrum 4.0.0.a0 - New Feature on: February 04, 2020, 09:04:04 PM
I like the change too.  Personally I think I would know whether or not the wallet I am opening is a new one or not, but I can visualize how a newer person might get confused.  Another thing that causes "pain" is when a person transfers BTC into a watching wallet, only to realize they lost the matching private keys.  Disabling this possibility is outside of Electrum's capabilities but any warnings about it helps.

There is a watching only warning?



It'd be nice if they had something like the seed input there where it suggests all the wallets avaliable as a bavigatable drop down scroller.
(I have a default_wallet and a bech32 native segwit one - and typing in the 6 letters gets tedious when I could just use 4 "be" <arrow down><enter>".

I submitted it to the free service on viabtc: https://www.viabtc.com/tools/txaccelerator

I think it got accepted, it just seemed to verify it thoggh.

They do offer a paid service but I'd wait a few hours just to see if it confirms.
4735  Other / Politics & Society / Can supplements be bad for you? on: February 04, 2020, 07:54:24 PM
I keep seeing vegan propaganda about people being able to get all the nutrients they need from supplements and it's much healthier or something because most people are deficient.

However, this isn't backed by the NHS or NIH who both claim that most people get the right amount of different vitamins and minerals. The NHS and NIH both go as far as to state that a long term use of supplements could actually be harmful to the body. I'm guessing the doctors have it right but since both don't cite sources it's difficult for me to work it out.

I'ma make this self mod, I don't plan to delete anything but if somethings too spammy I reserve the right to delete it. I'm after an intellectual debate, I won't delete differing views especially if they're empirically backed.
4736  Bitcoin / Bitcoin Discussion / Re: [VIDEO]The Empirical Proof of Bitcoin's Real Value Being Zero on: February 04, 2020, 07:29:24 PM
The monotonous computer generated voice in that video was extremely annoying.

You don't utilize Bitcoin, but transferring it from one address to another. A car can be both, utilized and transferred. Bitcon can only be transferred. That's why one cannot use it for want satisfying. And that's why it is worthless. If the only thing that one can do with X is transferring it to someone else, then X is worthless by definition.
Modern cars lose 14+% of their value every year though too so they're not great for transferrability and recouporation.

Cash can't exactly be utilised? Interest is a by-product of inflation and how well an economy is doing. If you sit with cash in your house, it's losing you money.

Gold is not valuable due to declaration but due to utilization in dentistry, medicine, electronic, aerospace and jewelry. Bitcon can only be valuable due to declaration.

Well not really. Gold is a bit like Bitcoin now.
Most medical, electrical and chemical equipment uses platinum instead of gold since it's cheaper (even though gold is more inflated).

There are fairly worthless financial instruments people like to gamble with all the time and bitcoin may or may not be one of them. It's certainly getting a lot of hype but I don't think it's going to be the main coin in the future for payment systems - I'm not sure if a true cometitor ahs yet been found yet though either. Money was initally created to be a store of value, a promise that you'll get something for the gold you carry. As time went on it got stored in banks and people just transferred signed receipts to retrieve those funds, and then came fiat currency after that which currently aims to keep an economy growing for as long as it can by using inflation.

You're not meant to hold a lot of cash anyway, maybe the same can be said for bitcoin and you're meant to invest or hold other assets that actually pay you back (also there aren't many banks in first countries at least that acutally pay higher than inflation in interest).

4737  Other / Ivory Tower / Re: I need help understanding what trans people feel.... on: February 04, 2020, 06:50:31 PM
Well that went a little off topic by the end hmm....

I just can't picturea n idea of splitting up the camps so much between men and women. Statistically speaking, men are probably stronger and more intelligent (in certain regards), and women are more creative and better with organisation - but there are still many different outliers and confusions to this rule that it doesn't seem logical.



Also on your other topic of conversation, your penis doesn't become a penis until a few weeks after conception.... So you too have grown one of you're a biological male.

Can we not put trans people in their own category for sport?
4738  Bitcoin / Bitcoin Technical Support / Re: unfonfirmed transaction on: February 04, 2020, 06:29:58 PM
can experts pls tell me why this payment got no confirmations even after many hours

Blockchair have it at 17 Satoshi a byte which means it should take around 2 hours to confirm based on electrum mempool estimate.

You'll probably just have to be patient with it. Unless you have an ability to up the fee, where did you send the funds from?

Why don't you use ebay? The ts where a lot of tvses sorts of sales seem to happen for many reasons. Btc might not be good to use on your website since its irreversible and leans people have to trust you before sending the funds and you also have to maintain a good payment server.,
4740  Bitcoin / Bitcoin Discussion / Re: Why exactly 21000000 BTC on: February 03, 2020, 09:29:31 PM
Probably security reasons and for an ease of understanding. In saying what you've said we could have a dynamic reward every block to reduce the earnings by a certain amount but I think an event every four years where the new block reward was determined makes it easier to calculate how much you'd get from a block and how well you could profit. It also makes the calculations a lot easier later on. I'm not sure what the last block reward will be but there may be div2 underflow errors involved in producing a reward on your schema.
