> you are going to have a really bad day once the other miners notice that you can be fooled into wasting hash power on bogus headers.

What are you even talking about here? 900KB takes a fraction of a second to transfer on a modest internet connection, any miner with $10 a month for a VPS can transfer that is a millisecond. No one said anything about downloading fractions of blocks, you hallucinated that.

> Anyone sitting at the 32MB buffer would be getting their lunch eaten. This is about as fundamental as it gets, so you might want to do some reading - because you've clearly got a big blindspot.

What is it that you think is even happening? Blocks get sent out. One has 32x the transaction throughput. Why do you think 32MB or more would be anything other than trivial to send and receive? Any miner can send and receive that in a second.

> I don't pay much attention to the joke coins.

Bitcoin cash already has more sustained transactions than bitcoin. Maybe you should reach beyond the propaganda of /r/bitcoin

> it even has a name: the selfish miner strategy.

Miners that do that take the risk that someone else will propagate a block before them since they didn't share the previous block they found. Empty blocks have much more of an impact on bitcoin because the throughput is so constrained. Empty blocks do not have much of an impact on the usability of bitcoin cash because it has plenty of throughput. A miner maliciously mining empty blocks on bitcoin will also leave a lot of money on the table because they won't get transaction fees.

> you obviously thought you knew how things worked, and you obviously don't

Everything you said is either completely made up or an exaggeration of some minor effect. In your last message you compared something with a 10 minute window to millionths of a second. For some reason you ignored this and ignored the actual numbers of modern bandwidth. You keep using hyperbole but won't quantify anything because the numbers don't add up.
Omg, people take these comments seriously ?
I actually don’t know. I don’t pay enough attention. My nose tends to get stuffy in cold temperatures, so it’s entirely possible that I automatically switch to breathing through mouth for that reason.
I will try to pay more attention to that.
And I would add some idea of usage. If the project has no revenue but some traffic / traction that is much different than code running on a development server.
One big flaw with login links sent to email is the delivery problem.

You can't assume the email will be delivered so quickly.

Who wants to get locked out of their account because the email has not arrived?

Login links can be a convenience feature but they must not be the only mechanism for login.
Currently it's done through the marketplace platform, so actually commissions don't track when you sell through other platforms. EIP-2981 aims to standardize this.

Depending on your view of platforms, this could be less than ideal. It should also be possible to modify the transfer function in the EIP-721 contract to be a swap, but this would require a new standard. In any case, it could be gotten around by an escrowed transfer with swap amount being set to 0. I don't think there is a way to prevent this.

This isn't so much "getting rid of passwords" as it is "delegating the password to your email".
I will help clear up some confusion if I'm able.

First, I don't think the big use case is for items being traded between different games. However, a system like that is possible. Blizzard would be a good example here, since their games have a high degree of cross-pollination, and they frequently offer promotions that unlock similar items in several of their games at once. So, owning a Blizzard "magic sword" token might give you a sword item in WoW, another one in Diablo, and a sword card in Hearthstone, each adapted for its own game. This is a small use case, in my opinion.

I imagine that the big use case is for any game developer (indies especially) to leverage the marketplace without having to build one, or be locked into one provided by a single publisher/distributor. The game itself does not have to be p2p as you're suggesting. Game architecture would remain centralized, and would communicate with a blockchain where the tokens are stored.

The process might look like this:

1) A player purchases an NFT representing an in-game item issued by a wallet owned by the game developer.

2) The player sends that token to a smart-contract address, also owned by the developer, with a memo that identifies their player account.

3) The smart contract notifies a centralized game server, then sends the token back to the player's wallet.

4) The in-game item appears in the player's inventory, within the game.

There could be any number of steps involved, and the contracts could operate however you'd like. The token could be destroyed after a single use (like purchasing keys for loot crates in CS:GO) or used and traded any number of times. The game server would have to keep track of which player account controlled which token, and update players' inventories whenever the token changed hands.

One more thing - NFTs can be programmed such that creators receive an automatic royalty (a percentage of the sale lands in the creator's wallet address) whenever the item is sold on the blockchain, no matter who is selling to whom. This could be huge for indie developers, who would benefit not only from selling the original items up front, but also from the long-tail resale of such items between their players.
Are you saying boxing is purely aerobic, or that anaerobic includes the word aerobic which means “with air”? I’m not picking up your intention either way. Boxing is a high intensity exercise which would at points be anaerobic.

It's something building after prolonged/multiple times. And runners are often not outside nearly as long as XC skiers. My runs are seldom much longer than an hour, and they start outside my door. XC sessions in the weekend are 30+ KMs and for me also includes long times outside getting to the tracks.
Edit: also humidity probably plays a big role.
I'm not talking about Electron apps but about VSCode specifically. I just cannot reproduce high RAM usage with it on any machine. Slack in comparison sucks bad for example, but reports of high memory usage for VSCode sound like fakes from non-users/haters.
You should see how much water your local water utility loses on the way to deliver water to your house. They're fascinating numbers.
My point is, that states have monopolized property transfers and there's all sorts of weird and arcane laws and practice around how you transfer property- especially real estate- and convincing the state to recognize an NFT as evidence of anything is going to be a real challenge.

ex, if the law requires an actual notarized handwritten signature to transfer ownership, what you and I do on the blockchain will simply not count when it comes down to it.

If I accidentally burn the NFT that represents ownership of my house I'm definitely still the owner of the house, there's no world where a government would shrug and say "I guess nobody owns it anymore, oops"
Yes, in my view Canonical betting on flutter is almost a testament to flutter doom. Choosing flutter is not the right choice anyway: it’s a lot more limited compared to Qt, it requires a language which is not used anywhere else, it’s slow and heavy, its tooling is incredibly complex, on some platforms won’t probably be ported anytime soon (if ever).
Is transcription really a critical/killer feature? Does the product fall down without it? Can it be done clientside and then the transcribed data be encrypted e2e alongside the av streams?

For me if it's not e2e it's a nonstarter, which means I'm not using the transcription feature because I'm not using the product at all.
There's a big practical difference between owning an original and owning a print. People have discovered secrets behind paint or canvas before. New technologies often allow us to introspect qualities of the art that we previously didn't know (chemicals used, techniques, tools, lifestyles, etc.). An original is a snapshot of history that includes tons of unique information that is simply not available in prints or nfts.

In the theory of depression as an attractor state in a dynamical system[1], exercise would be one of many small cures for depression. To cure depression, one would likely have to combine several small cures, none of which would work on their own. For example: diet, exercise, amount of sleep, timing of sleep, pharmaceuticals, behavioural activation, cognitive distortions, social life, life circumstances, as well as any physical health issues which could be contributing to depression.

I no longer have depression, and it was a combination of small factors which did it for me.

I'm really interested in learning how to fix bad files that have been recorded from a live RTP (or WebRTC) stream. These files tend to have gaps in their PTS or DTS, caused by UDP packet loss when the streaming took place.

There are a myriad of StackOverflow questions, mailing lists, forums... but never a well structured and comprehensive analysis of this topic. And FFmpeg itself, while being a feat of a software project, has such a lackluster and incomplete doc.

I'd like to see a discussion about recovering H.264 and VP8 timestamps, with minimal processing (i.e. not transcoding, if possible, otherwise of course it becomes an easy thing), which covered the whys and whens of using these FFmpeg options:

• -fflags +genpts

• -fflags +igndts

• -vsync

• -copyts

• -use_wallclock_as_timestamps

Does this book cover these options and the topic of timestamp reconstruction?

> If you expect that someone just wants to steal your money (and I am not saying such expectation is always wrong), perhaps you just shouldn't give them any.

This is indeed the approach I've been taking with some climate change charities: most of them have an "advocacy" component, and while I'd like to support effective emissions reduction projects, I'm not willing to contribute to the preaching for individual asceticism.

I have no issue giving to "some project + a proportionate share of central/overhead costs".

Unfortunately, it's often extremely hard to find a charity that is tax deductible where you live, part of employer matching programs, effective in running projects you want to support, and not performing activities you specifically don't want to support.

So I added filter_var(..., FILTER_SANITIZE_NUMBER_INT) around my INT fields (TTM and asking price).

$startup->ttm = filter_var($r->ttm, FILTER_SANITIZE_NUMBER_INT);

$startup->price = filter_var($r->price, FILTER_SANITIZE_NUMBER_INT);

Should be ok now!

> The more time and passion that creators devote to chasing the NFT, the more time they’ll spend trying to create the appearance of scarcity and hustling people to believe that the tokens will go up in value. They’ll become promoters of digital tokens more than they are creators.

This has always been an issue with art. Artists can be promoters of their art to support their livelihood (“sell out”). I do not think that stops making people creators.

And a small nit:
> Unlike some stocks, it doesn’t pay dividends or come with any other rights.

Many NFTs pay a cut of future sales back to the creator. For that reason, I think of NFTs more like a stock than a claim of uniqueness.
I too would like people to work to provide content for me for free, which is what you are asking.

I'd love it if you enjoyed programming so much that you'd code a database for me, please. I mean, i see little to no upside of the professionalization of computer engineering. Some things are just better done by amateurs, who do it for pure love of programming and for free.

On a more serious note, eventually amateurs stop loving it and get burned out, because it's a lot of work to make high quality content on top of a day job you hate. Just because they are amateur doesn't mean what they do is effortless.

And I'm not even going into the people who want amateurs to work for free so they can middleman and make money off of aggregated content, which is what techbros love to do.
I'd agree for a lot of the "random things getting NFT'd" - but it's definitely different in the art market, where right now quite some moderately known artists are making okay money from digital art through nfts. Not Mona Lisa kind of money, but it definitely does open up the art market for digital creators in a beneficial way.

Not so long ago the author warned that non-profits are a "magnet for sociopaths" because "their defining feature is to make no profit" and there's "no intrinsic accountability".
(https://twitter.com/paulg/status/1124254508232663040?lang=en).
I thought this was an odious and wrong thing to say for many reasons and it made me think that while he clearly has a lot of experience with non-profits of a certain kind or scale or connection to tech VC, maybe it's not so broad-based. And it's hard for me to square this attitude with this new blog post: If there's no intrinsic accountability, then how do unrestricted gifts help? Shouldn't gifts provide some of that accountability? The best interpretation I can come up with is "Apply very strict conditions to where you decide to donate, but when you do, do it unconditionally".
This is like an example of persuasive bullshitting from the article!

Poker amateurs play badly regardless of reason. Poker professionals wouldn't adjust their strategy based on some random guy at the table. The sample size is incredibly small for poker (as you said) but saying that the uncertainty you added affected the outcome is tenuous.

Additionally the best live poker players are entertainers in terms of they want to make you feel valued and that you have a chance so you come back and play more. They have a concrete financial interest in making you feel smart, funny, and competent. A true live poker pro always laughs when the worst player tells a joke and always says 'whoa that's interesting' after the worst player tells a story.
You're absolutely right! The companies I mentioned do hire many people with similar skills.

Do you think it's possible that this might not be quite the same as being in the same market and thus being a direct commercial competitor for a company's offerings? Otherwise every company is in the Human Resources and Accounting industries. Perhaps the companies in question are not in commercial competition with one another, and only competing for a certain set of skilled technicians? Do you think the point imtringued made about downstream suppliers might be relevant?

Again, you're completely right. There genuinely is a lot of overlap in titles and skills sought! It just might perhaps be possible that this is not quite the same as all companies concerned being in the same industry. Or perhaps I am wildly wrong! Can you help me with where I might have erred?

The question of how one chooses to define an industry quite aside, the degree to which San Francisco's employment depends on "tech" is easy to overstate. Based on news and this website, you would think it was a third to a half of SF jobs. While an easy and completely understandable conclusion to draw, this would be a dramatic overstatement.
You're not wrong about the other party needing to know your changed IP address, but that's still a result of higher level protocols that are leaking the abstraction of IP for addressing. You could use hostnames instead, or put some other addressing method on top of it to adapt. It's not commonly done since you'd have a DNS lookup before each packet, which would be horribly inefficient, but it's possible because IP itself doesn't handle the details of connections. IP itself is connectionless/stateless.

There is no concept in IP of a "user", "client", or other party that exists beyond the lifetime of that packet. IP is basically a stateless logical address sitting on top of some physical address with a few delivery options to facilitate traffic flow (like congestion handling).

Any connection state or concept of user/client/server/etc is held at either the TCP level, or for UDP-based protocol higher up the stack (commonly at the application level).

If you still insist on IP being at fault here, let's consider an analogue. If a user sets up an Amazon subscribe-and-save, and then moves to another city and has a different physical address, but the user does not inform Amazon by updating their address in Amazon's system (the higher level protocol), would you say that the postal service is at fault when the delivery ends up reaching the an incorrect party?
