I'd suggest contacting accelerators and other early-stage startup fund aggregators to see if any of their companies have a need, either to replace a prototype/PoC level product or are engaged in a pivot that would be sped up by acquiring your software.
Safari “opts out” of (blocks) tracking by default iirc. But users have to explicitly choose to opt out of iOS tracking.

Most people don’t even know about the tracking ID.

apple has millions of devs of apps who amount essentially to an army of gig workers who expect to be paid via ads or in-app-payments. if apple is not making sure the devs have a fair revenue stream , it's equivalent to abuse of the same kinds Uber is accused of. sadly, the terms of all similar platforms favor exclusively the companies and not the devs. Still, labor laws exist.

Max Tegmark was on the Sean Carroll podcast recently, talking about the different types of multiverse we could postulate may exist[0]. I found the quanta article fascinating, and I don't believe it's strictly speaking 'circular'. It can also be the case that multiple solutions exist mapping the relationships between a given set of fundamental laws. Prof. Tegmark discusses this in the '4th level' of multiverse which examines whether it's right to talk about a multiverse of all possible mathematically consistent universes.

GraphQL turns a social problem (getting your frontend and backend folks to coordinate with each other) into a technical problem that someone else already solved 75% of for you. That's a big win.

GraphQL doesn't do anything that you can't do with sufficient coordination, but coordination is actually one of the hardest parts of getting things done at a large company.
You pay the couple of percent whether you use the credit card or not, since there is usually no discount for cash or debit.

On the other hand, a credit card will give you back 1-2% of that in the form of cash back or other rewards. So in effect you are paying to not use a credit card.
if you use a cheap router instead of a switch the far end will only see one MAC address which is the one of the router. doing NAT then is as easy as it could be. You could literally use just about any router out of the box without even configuring anything. you can also add an ethernet switch behind this device easily. only limiting a port to a single MAC is therefore somewhat pointless. you would prohibit valid use cases (adding a switch) without hindering any nefarious user (guy with a cheap router). Also, NAT for MAC addresses is a thing although not necessarily the most useful approach in this case...

We used to have growable C stacks in Rust using that technique. They worked (though were too slow for us). It could have been fixed by using stack copying like Go does.
Sometimes databases use hash tables for indexing.

This is a natural match for a key-value store.

In particular, the following KV stores offer hash table-based indexing:

-Berkeley DB [1]

-Tokyo Cabinet (and its successor, Kyoto Cabinet) [2]

-Bitcask (used in Riak) [3]

In many benchmarks, the hash-based systems perform better than tree-based ones.

The real advantage of trees, as Berkeley DB manual says:

> Btrees are better for range-based searches, as when the application needs to find all records with keys between some starting and ending value. Btrees also do a better job of exploiting locality of reference. If the application is likely to touch keys near each other at the same time, the Btrees work well.

And there is the actual answer to the question in the title.

TL;DR: Why? Because you can do range queries and traverse sequential elements faster.

Are ads a lot worse on Safari as a result of this price drop? I’ve tried going tracker-less before (e.g. on YouTube) and the ads get hyper spammy. There was a large shift, too, in the spamminess of display ads a couple years ago as Facebook took all the high-quality ad dollars. There are several news sites that run such spammy ads they usually crash the browser.

> social media ... undermined the democratic process ... right into people’s ears and hijack their brains ... by swarms of “influencers,” propagandists, and bots

"Hijack their brains" is quite a violent metaphor. It's a frame designed to justify strong countermeasures. But what alternative is there that isn't more dangerous than the status quo, with the potential to become a Ministry of Truth?

It's either a free market of brain hijackers or a list of officially approved brain hijackers, take your pick.
How often do voters get a real choice rather than two slightly different sides of the same coin?

I seem to remember multiple presidential primaries in the US where progressive candidates get side-lined within the party as either un-electable (long before actually competing at polling stations) or get kicked out due to technicalities meant to steer watered-down right-centrists into the general election.

I'm not talking about some right-wing conspiracy, I'm talking about basic mechanics of the electoral process that are unfair at the party level, in media, etc.

As one example, I might cite how current candidate Andrew Yang barely gets time to speak at debates while others polling at the same level get 2x or 3x as many minutes to speak.

Another example might be the way Bernie Sanders was all but eliminated by backstage machinations in the Democratic party in 2015/2016. How are voters supposed to vote for true progressive candidates who want to change the system in a major way if they cant even compete on an even playing field
I agree that ads serve their purpose. Their proceeds allow websites to exist and motive entrepreneurs to create them in the first place.

My point is indeed that people go to grocery stores to buy food, not to spend money. Doesn't mean cashiers aren't justified.

It is an upper bound on the growth. But _what_ you're upper bounding is not specified.

Big-O notation works on mathematical functions. In the usual case, the function you're upper bounding is the worst-case run time of a procedure for a given input size. But that's _far_ from the only case.
Once the trolls realized that they could convince enough people to join or believe them to impact the real world it was over for internet freedom. The people that have held power for generations don't like losing that power. It's a shame that we'll lose most of the good parts of the internet along with it too, and all we'll be left with is a platform for entertainment of the most clicks. The internet can't route around broken culture.
Because indexes are decoupled form the data (so to speak) and one could easily have more than one index.

> To solve the problem, Google announced a different approach to HDR in a Nexus smartphone back to 2013. It was using time stacking.

I don't think time stacking is the appropriate term to use here, as standard HDR is also doing "time stacking", in that it takes multiple photos with different exposures across a small interval of time. Maybe "Fixed exposure fusion"?

I think there's a lot more to be done in computational photography, in research and engineering. In fusion of images from multiple cameras, we're barely scratching the surface. Exciting times ahead!

I hope you’ve already come to terms that you will probably see no return on the time you invested in the past two years, and that you are not simply still in the denial phase trying to squeeze something out of your efforts.

If you sell your code, the most it would probably fetch is somewhere in the low three digits, and it would probably be snapped up by someone who doesn’t care about the business they just want to have a beefy open source project as part of their resume or portfolio (which is basically the smart way to get open source credibility without toiling for years to no end, think about it, 300 bucks buys two years of open source experience).

If I were you, I’d beat them to the punch and open source your project and move on with your life, let others maintain it and maybe make it into something great.
> No. TLS certificates have nothing to do with domain ownership or the businesses providing services behind them.

> Anyone can buy and transfer certificates.

The registrar has a business relationship with the domain because the domain was purchased. The domain's owner uses DNS to point to an IP address. The client connects to that IP address and verifies that the IP address knows about the domain. "I paid for you to see example.com at 1.2.3.4" and "1.2.3.4 is responding to the name of example.com" completes that relationship.

With Letsencrypt, anyone can get certificates for free. And you certainly can transfer your private key and certificate information to a third party. That won't stop you from being liable for any malware served by them because you are the one who owns the domain. Unless you transfer the domain too. Then it's all on them. The third party. Hope you transferred the IP address payment too.

> Besides there are actual business contracts in place so there's no need for such tenuous connections over domain names in the first place.

Business contracts don't mean shit to me because I can't inspect them. I can inspect DNS, however.

> As for your disagreement, what's your basis for claiming that publishers can build, operate, and scale their own adtech infrastructure and salesforce?

Publishers can just as easily create advertisements and host them on their own website the same way they host any other static content. Scaling advertisements is just as easy (or hard) as scaling any other web services. Once upon a time businesses actually employed people for their sales departments instead of offloading it to a third party.
I noticed this from the paper:

> Note
that a user who has acquired a group’s GroupMasterKey and then leaves the group (or is
deleted) retains the ability to collude with a malicious server to encrypt and decrypt group
entries. We deem this risk acceptable for now due to the complexities in rapid and reliable
rekey of the GroupMasterKey.

Does this mean that the server and a deleted user can always collude to get the deleted user readded to the group? Also, is there no provable audit trail of who added or deleted whom? Unless I'm misunderstanding, it seems like deleting a user is therefore enforced only via server trust, but please correct me if I'm wrong.
"Occasionally, when the table is growing, your normally fast O(1) insert involves a slow O(n) scan to move to a bigger table."

This my impression and it seems like it implies that the "hash table has O(1) access" is bullshit taken as a general formulation. The situation is essentially, hash tables can have "O(1) access" time at a certain size and if tuned for that size. BUT that seems an abuse of big-O notation, which is meant (originally, in math) to mean "as you go to infinity" and you can't really have a data structure that mains O(1) as it's size increases to infinity.
This goes to a basic framing issue that crops up all the time in economics. [Situation] => [Authorities Do Something] => [New Situation] then everyone assumes that the authorities were primarily responsible for the change.

It seems like pretty intuitive logic but it doesn't make any sense on inspection; people adjust to changing economic circumstances much faster than the authorities can change things. The situation will change quickly even if the authorities do nothing. Lessons that get 'learned' about crises and responding to them are probably a build-up of rain dances rather than actual knowledge.

It is a situation primed to promote economic witchcraft. Nobody agrees with which parts of are the most cargo-culty because political groups generally support the stupid ideas which happen to favour them.

Product Zeitgeist Fit: A Cheat Code for Spotting and Building the Next Big Thing
> That fails to address both problems stated by the OP

This is wrong and unfair. One of the major problems the OP has with Docker is that many software builds are unreproducible, encouraging many people to deploy binaries of dubious quality. Nix tries to solve precisely this problem through better tooling which makes it easy to ensure that its packages are reproducible and its dependencies easily verifiable. This is also what makes Nix distinct from Debian, which tries to improve package quality through policies and community collaboration.

> Nix requires the build process to be "free from side effects"

I disagree that this makes Nix irrelevant to the discussion at hand. Another gripe the OP had with Docker is that it sandboxes entire apps, making it a blackbox. Nix does sandboxing on a more granular level, which provides more transparency into individual packages.

They cook a whole lot, for a variety of reasons. Many of these countries are less wealthy (can't speak to some of the wealthier countries like Singapore), and many have multigenerational households, where other generations help with household responsibilities, among other things.

As an aside, it's also interesting how big a difference the home-cuisine is versus what you may think of as that cuisine in many cases. I like to point at The Key to Chinese Cooking (https://www.amazon.com/Key-Chinese-Cooking-Irene-Kuo/dp/0394...) as a starting point for something more akin to Chinese home cuisine.

Well, yes, you lose the data if you lose all the hardware that is storing your data. But that's strictly better than the current case, where RAID controller bugs, SSD firmware bugs, "bit rot", etc. take out your files for absolutely no good reason.

The cloud is not made of magic. There are some things that work well, like immutable object stores that are okay with eventual consistency (S3 as an example), but these stores do not work well for things like databases, or logs, or editing video.

O notation is asymptotic by definition. The sentence

Lightning isn't an IOU, its actual Bitcoin. What you are doing is trading payment states in channels, these payment channels contain real Bitcoin, locked in smart contracts. You can settle (and close) for your channel for Bitcoin any time you like, and there is a punishment mechanism if you try to cheat (steal) and replay an old channel state.

This style of network, or a higher order version of it will certainly be the way that we further decentralize our economy and scale to every human and system. It is nonsensical to store full transactions between everything in an immutable ever growing data structure for all time. You can condense what needs to be stored forever in channels, or go further smaller still and store commitments+proofs.

We need to move past the blockchain to store all the things model. It was cool when it was small, but we need to be thinking about how to implement higher order payment or economic concepts rather than raw txs.

Finally, to your point about businesses not trading in third-party checks... Kinda! When the store takes your payment over the PCI network, the card holders bank and the vendors bank trade some payment state between each other, and delivery of funds can take days to clear. Its all businesses trading slates, e-checks, e-balance sheets. In essence lightning isn't too dissimilar to how things work now with electronic $s.

You omitted the most important reason why blocking is necessary: malicious and deceptive ads.

I want to check a story by my local newspaper. I don't have my phone handy so I borrow the nearest work computer that isn't typically used for web browsing. I open an incognito window and go to the website, click on the article, and read through it. I leave the page open while I go back to work. Sometime while I'm not paying attention one of the many ads on the page refreshed because when I turned back instead of the newspaper I see a full-screen message that my computer has been "hacked". There's an pseudo-unclosable alert box warning me not to turn off the computer and to call "Microsoft" at some phone number. This computer didn't have speakers attached, but if it did I suspect they would have been making noise or using text-to-speech to read the fake warning.

This is a daily occurrence for thousands of unwitting computer users. You can't blame the victim by saying they were doing anything to make themselves vulnerable. I saw this happen on a continuously patched and vulnerability-scanned Windows 10, running the most up-to-date chrome. While visiting the website of a mainstream web site operated by a major newspaper syndicate.

I put the responsibility to stop this on the ad networks, and the site operators who partner with them. Until you can guarantee that none of the ads you serve are malicious or deceptive, I'm blocking everything and denying your revenue stream.
