Once you have received a number of payments, then you can move them all to your main wallet in one single transaction. Moving them altogether like this rather than individually will save you on fees as well as consolidate them all in to one input, which will save you even more on fees down the line.
Doing this will reduce privacy for the OP because all of his incoming transactions will be associated with each other. It will also be more expensive in terms of total transaction fees he pays because he is paying transaction fees to send bitcoin to himself.
2122  Bitcoin / Development & Technical Discussion / Re: Will there ever be any monetary incentives to run a full node? on: December 06, 2020, 09:28:39 PM
I challenge this claim of you. I tried it out but couldn't find a single reason for an SPV wallet to wait for more confirmations just because of using SPV technology. Please elaborate. Smiley


In the top situation when a split has happened, the full node is well aware of the existence of the other chain (it may be 1 block to whatever number) but it will not tell the SPV client so SPV client doesn't know there is a split. The full node is only following one chain (Node A the red chain, Node B the blue chain where circles represent blocks).
* If the SPV client is connected to Node A and its tx is included in a red block it will think that its tx is confirmed without any issue.

<>
I believe you are referring to a Sybil attack. I don't think this is a problem unique to SPV clients solely because it is a SPV client. You might argue that SPV clients tend to have certain behaviors that are different than full node clients that might make them more vulnerable to a Sybil attack.
2123  Bitcoin / Development & Technical Discussion / Re: Wallets Addresses per private key on: December 06, 2020, 09:22:54 PM
You generate a private key with randomness, and you use the private key to calculate the public key. In other words, your private key can be described as a random number, while your public key is a derivative of your private key.

You are correct, you should generate a new set of keys for each time you receive bitcoin.

It would probably be best in most cases to use a deterministic wallet to generate your keys. You would create a 'master' private key that is used to calculate an unlimited number of private keys, and those private keys can be used to calculate each public key. This makes backing up your keys much easier, and you will have effectively pre-generated all your keys at once.

These threads are black hat SEO to help the link's search engine results. I believe at least one of the patrollers (staff) uses a bot to stop at least some of these posts via automation.

IMO, the best way to fight off these types of spam attacks would be to prevent search engines (and maybe guests) from seeing posts made by low-level accounts unless the post has reached an age that it would be expected for the moderators to have been able to remove the post if it is spam. For example, if the mods have always been able to remove these posts within 6 hours, search engines would be unable to view a post by a newbie unless the post is 6 hours old.

If you don't need to know which user sent you the donation, simply just use a single static address.

Address reuse leads to a reduction in privacy for everyone, and incremental reduction in security (I am guilty of this sometimes, as are many other people).

Ideally, the OP should generate a new address each time he receives a transaction, but at a minimum, he should generate a new address each time he spends any coin he received.

There will be no need for rounding down millisatoshis on channel closure once we increase the number of decimal places on-chain. It is bound to happen some day.
That would be bigger than the scaling debate.
I would be surprised if this was the case.

Increasing the max block size was one solution to a technical problem that it was unclear was an actual problem in the present. Increasing transaction value precision will be the only solution (that I can think of) to a problem, and it will be very obvious if it is a problem, as it would be reflected in the price of bitcoin.

Maybe he will grant himself a pardon before he leaves office?

Smiley
Trump can only pardon himself for federal crimes. The state of New York would not be subject to any pardons that are issued by the President.

On that note, I do think should and will pardon himself on the way out of office. There would be too much pressure from the left to engage in politically motivated investigations and prosecutions that would end up further dividing the country.

I would say the medium article is something closer to drumming up interest in an altcoin rather than an investment. I would compare the article linked in the ad to an article educating the reader about bcash or etherum.

Would an article discussing why (in the author's opinion) bcash is superior to bitcoin be allowed? If not, this ad should probably not be allowed. (I don't think bcash is superior to bitcoin, however, I do support the free-flow of ideas, and rigorous debate; people should believe bcash is inferior after reading an open discussion with a maximum amount of information available).

Pretty sure it's not the part about opinion or about technology that is the issue here.

It's the part that Theymos thinks that the advertisement that Phore itself is using isn't advertising an investment but they are advertising the the technology behind what they're building and the usage of it. It's easily arguable that there is a DIRECT LINK between talking about the technology behind a coin and a product trying to drum up some hype for people to buy the coin.

Not sure if I'm a fan of advertising products like this, kinda sounds like a wormhole of people coming in and talking about the wild claims of their coin even if there is little to no chance of any of that coming to fruition. Not knocking the idea of Phore or whatever as I really know nothing about it, but still.
My opinion is that the medium article is promoting the altcoin. I might compare it to an altcoin whitepaper, although a whitepaper would be more technical.
As an aside question, what would your thoughts be about advertising the more legitimate companies in DeFi such as Compound, Aave, and so on?
I would not allow an advertisement based on the company being 'legitimate'. There are plenty of legitimate companies that go bankrupt for reasons not being an exit scam, such as poor market conditions, or bad strategic decisions by management. Also, a legitimate company today may turn into a scam tomorrow.

I don’t think you can conclude it is not hacked. The account has made a single post in the past year and the post was two words.

that may be true but it is the safest assumption at least based on hist 4 pages of post-history and him suddenly posting doesn't really raise any suspicion of being hacked.
What are you talking about?

Someone making a single two-word post, 12 months after making their last post is not an indication their account is not hacked. (notice the double negative).

If someone is "wearing" their copper membership (or other paid membership), their 'position' will not display on their forum account. This means that someone such as a moderator will not show that they are a moderator if they are 'wearing' their copper membership.

IMO, it is probably best to force moderators (and other staff) to display their respective titles.
2133  Other / Politics & Society / Re: US Elections 2020 - very self such moderated on: December 03, 2020, 02:09:08 AM
Trump underperformed the down-ballot candidates almost everywhere. If the election stands, voters will have voted against Trump, rather than for Biden.

Loeffler should handily win as her opponent is especially radical in a Red state. Loeffler and Collins received a total of ~56% of votes, while her opponent only received ~32.9% of the vote.

There will be a show of force of fake votes, as they figure that after Joe and Hoe take office nobody will come after them and their vote fraud.

I suspect it'll be pretty much right out in the open.
If voter fraud is uncovered after Biden takes office, I would agree that it will not be investigated.

There are issues in PA such as not allowing GOP poll watchers to watch the counting of the ballots, however, I am not aware of evidence of sufficiently substantial and widespread voter fraud that would change the outcome of the election.

There are real issues with mail-in voting, however, the Republican opposition to widespread mail-in voting likely disenfranchised their own voters. The amount of effort put into voting for Biden per vote was less than the effort each voter put into voting for Trump.


Trump, rather than hurting the down ballot candidates, helped them in a big way by ensuring a huge turnout among the GOP supporters.
Republicans picked up about a dozen house seats, maybe more. The Biden administration will not be able to hire people serving in the house because the Democrat majority is so small.

This is probably better suited for its own thread, or even its own sub... I don't think Trump was well prepared to win the Presidency in 2016. His early administration was not well organized, which probably resulted in much of his first term being stymied

If you have the network capacity then it's better to just serve it locally (except, AWS bills your upload traffic too  Angry)
Your local ISP might not like it very much if you are uploading that much data.

Sorry, when I said locally, I meant on a VPS with another cloud provider with unmetered traffic, such as Hetzner.

I guess I have been doing too much of my work on the cloud to tell the difference anymore.
Ahh, gotcha.

I was under the impression that traffic out of the AWS network (for AWS) will count as egress traffic, and will be billed accordingly. Migrating your data from AWS to GCS will incur a charge from AWS for the amount of your data. There might be ways around this, I'm not sure.

As a FYI, you generally will not want to host files on a server. You will probably want to host files in a storage bucket that can be accessed by a server.
Amazon charges $0.09 per GB outgoing data, that's rediculous for this purpose (my current 5 TB bandwidth limit would cost $450 per month when maxed out). And Amazon wants my creditcard instead of Bitcoin.
I had used AWS as an example because I believed you used it for some of your other projects.

Yes, transferring data to the internet is very expensive. You can use a CDN (content delivery network) to reduce costs a little bit. 5 TB of data is a lot.

Separately, sorting lists are not scalable, period.
Actually, sort performs quite well. I've tested:
10M lines: 10 seconds (fits in RAM)
50M lines: 63 seconds (starts using temporary files)
250M lines: 381 seconds (using 2 GB RAM and temporary files)
So a 5 times larger file takes 6 times longer to sort. I'd say scalability is quite good.
I think you are proving my point. The more input you have, the more time it takes to process one additional input.

To put it another way, it takes 1 unit of time to sort a list with a length of 2, it takes 1 + a units of time to sort a list with a length of 3, it takes 1 + a + b units of time to sort a list with a length of 4, and so on. The longer the list, the longer it will take to sort one additional line.

As a FYI, you generally will not want to host files on a server. You will probably want to host files in a storage bucket that can be accessed by a server.

If you want to update a file that takes a lot of resources, you can create a VM, execute a script that updates the file, and uploads it to a S3 (on AWS) bucket. You would then be able to access that file using another VM that takes fewer resources.

That may save on local resources but you will be paying a lot of money per month if people download several hundred gigabytes each month particularly if the files are large like the files hosted in the OP.

Some results: The awk-thing uses just over 1 GB memory for 10 million addresses. So for 1.5 billion addresses, a 256 GB server should be enough. At AWS, that would cost a few dollars per hour.

This is not a problem today, but I can potentially see gifs becoming disallowed if enough people are sufficiently annoying with their GIFs.
In Firefox: about:config, search: image.animation_mode, set to "once" (type the word).
Sometimes it takes me months to realize a certain image is animated.
I don't think the administration would want users to have to make changes to their browser configuration to not be annoyed by random gifs in threads.

....

Most of the time that countries are seized by dictators, they will first be legitimately elected, and subsequently, make radical changes to the court system, such as packing the equivalent of the Supreme Court (cough cough). Once the courts are on the dictator's side, any other changes made are rubber-stamped by the courts and the Dictator can do as they choose.

In Argentina, all it took was a number of well publicized deaths of leading judges and the others all fell in line. I can't recall if the murders were made to look like accidents or if they were right out in the open, executions. Seems like the latter but maybe someone down there can help.
The US has the US martial service that protects the judiciary branch. I don't see judicial intimidation much of an issue in the US. IMO it would be more likely for political judges to be appointed.

please add a poll option demanding a ban of people who, being accused of being cunts, reply with famous fine-art paintings of cunts.
I'm not adding more options to a running poll, that would give inaccurate results.
This poll is not going to get anything close to accurate results as it is. Bitcointalk polls are already not accurate because of the ease of sockpuppet voting, and the options are really not serious. I also personally often vote for poll options that are ludicrous specifically for the above reasons.
2140  Other / Politics & Society / Re: The Privacy Culture Manifesto on: November 28, 2020, 06:03:33 AM
Trump has warned about the dangers of unrestrained social media and abuse of Section 230.
Section 230 is separate and distinct from privacy related to social media.


I am generally a private person, and I do value my own personal privacy. I also am willing to acknowledge the benefits related to giving up privacy.

On an interpersonal basis, giving up privacy is what allows people to have intimacy with other people. Intimacy with other humans is one of the most rewarding things. Refusing to give up some amounts of privacy will not allow you to reap these rewards.

Somewhat similarly, giving up some amounts of privacy to companies may allow those companies to provide a more customized experience that is more interesting to you. The benefits are not the same as the above but are still benefits.

Ultimately, individuals should be in control of how much privacy they desire.
