I had a similar error on firefox for mobile, but I made some pancakes and it seemed to go away after that Grin...

~snip~

Once it went faster again I kinda liked that style, the quotes didn't really work as well but everything else was great (very minimalistic).

Ahhh in number theory, base5i refers to a number base (more on that later) the only redundancies are a checksum and the 1, all should be kept just in case.

A base refers to the number system used:
denary which includes symbols [0-9] only
Hexadecimal is another system which includes [0-9|A-F]
Binary is [0|1]
Octinary is [0-7]


Base 58 is [0-9|A-Z|a-z] without zero, uppercase I, uppercase o and lower case l.

I have two clients on the same wifi network and they connect to each other via IPv4 and IPv6 how the hell is that possible?

If they both have the longest chain or one has a chain longer than the other then they are the fastest for a connection. Every so often other nodes they are connected to might get pinged too.

Generally if you have a fast switch/modem the lung speed should be less than 1ms and the rate data can be transferred at between them should obviously be higher.

I'm not sure if there's something bitcoin core uses that scans the home network for anything that it can connect to (it'd normally just have to ping 192.168.0.255 for a response from anything that can accept a connection and understand the packet sent to it).
5124  Bitcoin / Development & Technical Discussion / Re: How do nodes connect to each other? on: October 20, 2019, 01:29:59 PM
Bitcoin node software comes with a predetermined list of nodes that should be avaliable when the software is run.

After the initial run, the software asks those nodes for a list of recommended nodes (which has to be less than 1000) it adds these modes to peers.dat and picks the fastest few to connect to (normally 8 or so) it wants the one with the longest chain too so that it knows its up to date. So if a node has a lower speed but a longer chain it may download the next block from it and connect to it rather than the fastest node in order to stay up to date...

When the node is turned on again, it scans its peers.dat and checks the connections that are still active from it.

If you're trying to save on a character just take the separator off the start (I. E the starting 1, 3 or bc1) and then add it when you need it. Or just use a higher base... (but you'll have to convert it before putting it into wallet software for sending).

But your op is ambiguous you might have better luck posting in your native language.
5126  Bitcoin / Bitcoin Technical Support / Re: TXs that include unnecessary UTXOs on: October 19, 2019, 03:49:53 PM
It's to save money on fees. Most wallets have an option somewhere that let's you decide whether to favour lower fees or privacy.

It always a good idea to consolidate all of your nonprivate inputs while you're not in a rush too... At the same time, most wallets let you decide which inputs you want to spend so you could spend just the 0.08 and all the other utxos will remain the same.

I think this also goes to reducing the size of the chain state for full nodes too as there's less data to hold if you have 2 utxos from 2-5+

I've been considering making a topic on asking someone to do this since wednesday.

Great job, I'll have a watch of it all (I just watched the first 3 minutes) and see if I can offer anything but it's started off pretty good.




edit: after watching it it looks really good for newbies as a roundup of the basic features of the forum. I'm not sure whether something on the rules more specifically might be helpful but I'll leave that up to you to decide as it could be a tedious readthrough of what is already written.

If deemed neccessary by the community (perhaps you could make a poll) theymos could add a link to it from the registration screen). I mean literally doing a youtube search of bitcointalk.org the first two options you gert are ICO SCAM and Bitcoin SV (that's not something we want)...

I can fill this, I can offer 0.02BTC for 3ltc (I'd rather stick to round numbers).

MNSb3dkVW3WipJTL17aDZpPKR4W1Vpp7k3 is my ltc address (if you need legacy I can try to get one).

Did anyone work out what site that address belongs to?

It can't be coinbase as they do 1 to 2 and use native segwit. Binance merge a ton of transactions into one so it also can't be them. And bitmex do the same as binance...

Trying to come up with the reason why somebody would invent a story like this. Struggling to come to a conclusion as to why anybody would be so weird.

Because they then come back later and flat out beg for BTC
That or they come back later as another person who was also hacked, and try to fish for money to start a lawsuit.


-Dave

It's like the loan listing for $5-10... They want something from it and if they can work out it works then they'll keep doing it every few months so enough people forgot.

Try once more if not then just keep it.

The last one expired, can you send another please?

...and if it fails, please send me a bitcoin wallet address that I can send the funds directly to you...

5131  Economy / Trading Discussion / Re: Are there any good videos/tutorials on cross and isolated leverage types? on: October 17, 2019, 09:35:18 PM
Make a search on google or youtube, man.

I did yesterday. Thought I'd open a topic here to see if anyone could provide anything before commenting on youtube videos to ask for the person to make one... The closest I came to finding out what it is was watching multiple people trying to sell courses on signalling (YouTube really needs to sort its algorithm) or those guys need to stop putting "cross" on all their titles...

I googled this topic for you and one of the first articles I found with a somewhat basic description of cross leverage was written by PrimeXBT and you can view it here.

Thanks (someone actually bothered to help)... It seemed weird that my leverage for crossing litecoin seemed to go up but my liquidation price went down when most of my funds were in that position already.



If anyone uses bitmex Cross often enough do you know if the leverage increases as the unrealised pnl goes up or do I need to adjust this manually. (although it might just be best to wait for these contracts to mature and find out myself from experience)...
5132  Economy / Trading Discussion / Are there any good videos/tutorials on cross and isolated leverage types? on: October 17, 2019, 06:56:53 PM
I've been using isolated leverage on bitmex and am starting to look into cross leveraging. Are there any good sites that explain how it all works as I'm trying to practice by putting some amounts into cross positions but I'm trying to work out when it's better to use isolated leverage than cross leverage? (I assume it'd when you want to take on large amounts of risk at once?)

@dabs, if you're not in a rush I'd suggest just leaving it to its thing...

According to electrum, it should take 1.1 sats per byte to confirm in 5 hours (25 blocks) so give it up to about 8 hours and it should confirm.
5134  Economy / Trading Discussion / Re: Bybit Review: The Best Margin Trading Platform on: October 17, 2019, 01:00:54 PM
I'm sure I paid 0.0005 to withdraw btc on that site so you might want to amend that if its your site.

I'd like bybit to at least get ltc too as 9ne of the trade pairs...

It's quite a nice site to use on mobile compared to bitmex as bitmex is really not optimised for mobile...
But the issues most people. Have with bybit is that it's very new and might not have as good security/might exit scam still. I don't think the overload error and lack of scam wicks (but I thought bitmex was based on an average anyway?) is enough of an issue for trading especially if you set your take profits and stop losses an sypur limit order all at once and don't rely on the market. You should be able to make a tp and sl before the limit if you have the limit on cancel box checked.

(also bybit claims to have 24 hour support which bitmex doesn't)...

I thing you've got the url wrong somewhere? I can't find that on imgur when putting in the link.

Edit: ah it's this

Yeah I thought it was the random photo album that comes up when you type a link wrong... Seems imgur has had some updates.

Ahhh. I might have been on a public network with an overly strong firewall (didn't get a notification of that message either). Lmk when you're online and I'll send another.
5138  Bitcoin / Development & Technical Discussion / Re: How to export entire bitcoin blockchain into database on: October 16, 2019, 07:25:20 PM
I'm pretty sure you can use the api from blockchain.com to get a copy of the blocks in csv (but it might not have native segwit transactions).

There was a user here who was doing data dumps recently you might want to do a Google search for it. It's worth noting you're not going to be able to open it with excel since it'll be 250gb+ in total after conversion to human readable formats... A few text editors won't have a problem with it though (especially the old ones that used to open files in segments)...

https://github.com/organofcorti/bitcoin-blockchain-data?files=1 as an example from a quick Google search, this is written in R (I didn't get to have a look through it but R is C based).

From where did you get the "52" value? I am seeing that no posts were deleted by mods:


I saw 52 as well before, perhaps that's the default value for when vod's script has a div zero error.

You are completely off track.
Here we are not talking about the contents of the posts deleted by mods, BPIP keeps a log of the number of posts made and the number of posts deleted by mods.

@nc50lc btw, there's no point to discuss how many posts got deleted on OP's new account (created yesterday).

There's still 9 posts of his that have been deleted and not by moderators though - which might be his issue?

(cou'dve caused him to go from newbieto brand new, hency why he said lvl1)
