Just addnode your IP above,  it looks good, connected.  Now my node gets three connections for the first time.

Excellent.

I am working on a new announce thread. I actually had one mostly done, but someone did a proof read on of it and commented it looked like crap, so I passed it to someone who does editing for a living and she agreed that it read like crap. So, I will start again, hopefully this weekend.

Let me know if the node gives you any issues.

Wrong part of the forum, this should be under  Economy > Marketplace > Service Discussion > Exchanges
Or the altcoin discussion.

Either way, unless it's one of the tokens listed here:

https://support.coinbase.com/customer/en/portal/articles/2630943-supported-digital-currencies
You cannot get to them as coinbase does not support them.

6584  Bitcoin / Development & Technical Discussion / Re: Blockchain explorer reads from a chain not from external database on: July 21, 2019, 08:33:17 PM
Many desktop/mobile application usually uses same practice, sacrifice performance/complexity for faster development to continuously satisfy customer with new features.
But it's horrible practice in this case since the application won't scale with complex hardware (multi-core CPU, multiple CPU, big RAM & multiple server).

I see that way to much. But, it's amazing when looking at the bloat how nobody cares about it anymore. The internet really broke programming. Now, somethings wrong you can download an update. 25+ years ago, you had to mail your customer a disc and that took time and money.

It's also the possible there's bottleneck with other hardware (such as CPU, GPU or RAM), bottleneck with slow internet connection or the task performs is either CPU, GPU or RAM intensive tasks.

True, but you have not had a good laugh as a hardware guy until after telling everyone it's the shitty programmers fault that it's running slow; you update the hardware to the extreme, and it's still just as slow because they have no idea how to optimize their tables or fix the poorly written query.

Another point to be made is how far do you want to "cheat".
I just did a test with an old scrypt coin with an Iquidus explorer that I am running.

The explorer and node are on a Hyper-V VM that is running off an average SSD
I wiped the DB and restarted, 1 GB of blockchain took about an hour or so to sync.

I created a 2GB ram drive on the Hyper-V server and copied the VM to it and did the same test. So instead of a "slow" SSD it came completely from RAM.
Under 10 minutes and done. I don't have an exact time, I was not staring at it. I figured I would check in 15 minutes to see how it was going but at the 10 minute mark I looked in and done. so ~ 6x faster.

You can hide a lot of programming things with better hardware. NOT an ideal solution but it can help you with your coding.
If you have a function that takes "X" time to run, then you do what I did you know it now takes 1/6 of "X"
If the next function you do takes "Y" time to run but running it from the ram drive still takes "Y" time, then there is another issue.

Just my thoughts. I am not a programmer I'm the hardware guy. But I have seen some things that were SOOOOOO badly written that 5 x the hardware did not make a difference in the application speed.

They have just released another update. The changelog indicates that they fixed a few bugs so it might now work properly for you. Did you reach out to the developers?

No, it was a busy weekend. Going to try it tonight.

priced pretty high, plenty 8gbs going for $75 on here

Sold a 4 pack for $450 last month, kept this one because I was going to "do something with it"....Which was keep it in a box 5+ weeks.

If it sits here too long then I'll drop the price.

6593  Bitcoin / Bitcoin Technical Support / Re: Strange hight amount BTC UNCONFIRMED TRANSACCIONs with low fees in one adres??. on: July 12, 2019, 07:07:56 PM
If only more people would manually choose the fee that fits their needs, instead of letting their wallet choose a high fee aiming at fast confirmation Smiley The fee market would work much better that way.

Without getting into a long discussion here, the issue is a lot (most?) people are paranoid about confirmation times and don't 100% understand the concept of "is you pay a bit less it might take a while to confirm but unless you need to have the BTC there now it does not matter"

I *personally* like the Current best transaction fees info at the bottom right of the btc.com page. I find it fairly accurate. If I for whatever reason need it to be in the next block, I use that number (perhaps +1 or 2 % to be sure)

If I am in no rush but want it in the next few hours or so, I usually use 10% to 15% less then that number.
If I really don't care I use 25% less.
If it's just a consolidation. I wait for the weekend and can usually get a 1 or 2 sat fee.

*I* understand how it works and don't think it's that difficult. You (LoyceV) are the same.
There are a lot of people who have been introduced to BTC and like the concept of it, but don't really understand the inner workings of it so they just go with what their wallet says.

It's up to us to educate them.

Someone should do a video.

The 8-July update broke it on my phone.
Open it and it instantly crashes. Anyone else having this issue? Since it's beta software it's on my phone that I use for testing so there could be other things causing the issue. But, before I spend time this weekend wiping and re-setting it I would check here.

No, I didn't ping out to the developers yet.

6598  Bitcoin / Bitcoin Technical Support / Re: Raspberry Pi 4 performance on: July 07, 2019, 01:10:41 PM
I can't say this strongly enough.

IF you really want to run a node on an RPi think about the following.

If at all possible do not run it on the SD card. Get an external drive and make it an SSD

If you can't or don't want to. GET A GOOD SD CARD. There are good cheap ones out there but they are few and far between, spend the money and get a real name brand.
The cheap ones degrade quickly and core does a lot of reads & writes.

6599  Bitcoin / Bitcoin Technical Support / Re: How can I increase the appeal of my node? on: July 07, 2019, 12:42:13 PM
Do you have a discussion as to the other info on the public Wi-Fi?
I have some thoughts but they might be a re-hash of another discussion.
But:
1) Are you always in the same location? Or are you getting different IPs?

2) Are you sure it's the sporadic traffic is the fault of the connection and not your PC? When you get in a block it thinks about the block and if you don't have enough CPU you wait.

3) If you have a node that lets you connect make a note of it and then use addnode in your conf file to make sure you try to connect to it next time.

If you area using RPC calls from the wallet itself you will hit a wall. The bitcoin core wallet uses locks a lot of times to keep data structures clean. The same RPC calls will use the same locks. So if you are doing a lot of RPCs, it's going to lock and force the next call to have to wait for whatever to finish before moving on to the next call.

If you are reading the blocks from the disk and bypassing the wallet entirely, it could cause an issue if the wallet wants to do something and the file is locked because you are doing something.

If I misread what you are doing ignore this post :-) Only had 1 cup of coffee so far today.
