I noticed that as well. Maybe it's assuming a CPU cache and TLB miss on read which means going to the kernel. Also on write if it's a new page you are going to have to fault once for every page which depending on write size is like having to go to the kernel for every write. It can actually be good for performance in some dimensions to pre-touch pages in a loop.

I can't speak for Avi though.

I suspect he is writing from the perspective of a database implementor. For a database the page cache is not predictable in ways you want it to be.

For writes the issue is IO scheduling, when flushing occurs, and how much is flushed at a time and at what rate.

For reads if a page is not in memory you have to block a thread to read it. If you are thread per core this means you either have a thread pool on the side to do IO or you block an event loop preventing other work from making progress. Even having the thread pool on the side is problematic because checking whether a page is in the cache is not cheap either and requires a system call which is kind of self defeating.
>We are expecting google to feed us only the truth?

To be fair, that is how Google presents things like the snippets. There's no disclaimer for the answers.

Normal non tech users wouldn't know if these were automated and highly fallible, or manually curated and somewhat reliable.

Here's my go-to example, where Google says a quarter is worth 50 cents. https://imgur.com/a/oibA7

No disclaimer or indication that this is at best, a bad guess. Also, it's been this way for months and months, even though I post it everywhere as an example. I also clicked the feedback button quite some time ago and reported it.

I understand this case wasn't a snippet. But it was labelled "Top Stories" and probably carousel featured. That sort of thing, like rich snippets, implies Google is presenting it as something more than just a search result.
Most businesses I've worked for/with had one reason or another to scrape data from various places. Often it's watching competitors, but can also be part of an automation of some process that is already happening manually.
The Best Advice I Could Give to a Female Colleague About the Tech Industry
Angular constructor versus ngOnInit
I think humanity as a species is only just beginning to advance technologically. I grew up right when the world wide web was taking off, and at some point in my adult life realized that my generation is the first of its kind. The first for which a chatroom containing American, Japanese, French and Nigerian participants engaging in a realtime conversation from all corners of the globe is not only possible, it's normal.

I had to step back for a moment and realize that just 10 years before I was born, such a feat was technically possible, but required massive planning and a high degree of skill involved in all participants.

100 years prior, it was impossible.

The rapid exchange of information afforded by this technological advance is utterly disruptive, and our society is still figuring out what to do with ourselves now that we're no longer separated from each other by huge stretches of travel time and long delays in information exchange. I must wonder, then, if this is the turning point in any global civilization? The part where the intelligent beings on a world can actually work together to solve problems at such a larger scale than any individual can observe.
Swift also supports associated values with enum cases, so you could do something like this[0] and get type-safety. Now you could only associate a URL type with a link attribute, or an NSColor type with a foregroundColor attribute, etc.

However, you can't (at least currently) add new cases to someone else's enum (the way you can add methods). So if I decided I wanted my own custom text attributes (which isn't uncommon), we're back to type-unsafe land. We'd need the original enum to have an extra attribute case, like this[1].

Exactly, what happens when a credible news source has to _retract_ a need story?

Do we crucify Google for surfacing an expost facto false story?

It's not Google's job to verify sources of news. Could they algorithmically "guess" a credibility score and attach that to the newslink, sure, I suppose.

They don't need to be spacefaring, just broadcasting. Of course if there are 10,000+ aliens advanced enough to broadcast radio and laser, we do have to wonder why this hasn't led to the galaxy being filled up over the past 5 billion years. Drake's answer to this is that space travel is too expensive, cramped and lengthy to be worth it.

I'd like to see your proposal get a bit more concrete. Your request seems a bit more for "magic" than "AI".

You're not likely to succeed with "here's the query and schema" and have AI somehow figure out what the best plan there is. There's a lot of rules to observe for correctness, and you can't just try to execute arbitrary valid plans, because the initial query plans are going to be really bad. So you again need a model of what valid query plans are, and a cost model to evaluate how efficient a plan is, without having executed it.

I think there's plenty opportunities for ML type improvements, but they're in individual parts, less as a wholesale query planner replacement. I think the most likely beneficiaries are around statics collection and evaluation, incremental improvements to query plans, and some execution time -> plan time feedback loops.
> The great advantage of letting the kernel control caching is that great effort has been invested by the kernel developers over many decades into tuning the algorithms used by the cache.

Some other advantages:

The kernel has a global view of what is going on with all the different applications running on the system, whereas your application only knows about itself.

The cache can be shared amongst different applications.

You can restart applications and the cache will stay warm.

Yup the US is not far behind.

As far as "sovereign embarrassment," there is no such thing. If you want Chinese trade and embassy relations, you put out whatever news releases, go on television, press conferences, and at the UN General Assembly you stand up and proclaim exactly what Norway has said. It's an "embarrassment" in the poster's mind, but pretty much every country has done it. Then you go behind China's back and buy Taiwanese stuff and talk to the President of Taiwan in backchannels because everyone needs cpu's, microchips, and cell phones. The level of hypocrisy is pretty high in global politics.

I do not agree with this, but it is the state of the world.
After upgrading to High Sierra and running into issues ranging from freeze ups to terrible bugs in the apps I use for work, I will never upgrade immediately after a launch again.

Contracting instead of developing in-house capabilities is completely destroying the DoD and American military effectiveness. The corruption around that is posing a real, impactful threat to national security.

Fuck these people and their "free market" lies as a cover for outright theft of public funds.

It's not just in the cyber domain that this is a problem, but the cyber domain is one in which the corner-cutting, half-assed nature of the corruption is most visible because the damage is most easily exploited by foreign powers.

Since this thread is broadly about Apple losing its edge as a fairly secure-by-default platform:

I installed Windows 10 on a computer and use it from time to time and the built-in anti-virus and malware protection makes me feel more comfortable running unsigned applications on Windows than I feel running them on OSX.

I find myself wishing that Apple would take similar responsibility for security (virus, malware) threats. One possible reason Apple is not doing this is because the next iteration of MacBooks will run iOS and unsigned apps will not be possible without jailbreaking.
I think you're entirely misrepresenting the problem.

The issue was that the data was being used in Google News, not Google Search. This doesn't just impact "what URL we follow", but how other pages get pulled in as "relevant". So we can be presented with "something terrible happened" from a news site, and "here's what we know about john smith" as relevant to the topic - without being told that the leap from 'something terrible' and 'john smith' was made by /pol/.
The Drake equation along with the Fermi Paradox are well known in conjunction with SETI's goal for the past several decades. Seth, Frank Drake, Carl Sagan and Jill Tarter have all publicly talked about their justification for being confident in SETI's eventual success. Sagan even wrote a science fiction book about it that was made into a movie.

Anyone including "4chan" in a list of media outlets is an idiot. (Or whoever enacts a system that automatically includes 4chan in a list of media outlets ... it's not important to users how they got to that result.)
Google shouldn't be vetting articles, but they are picking what outlets are considered "news" for inclusion in the news.google.com "Google News" aggregator.

Does anyone think 4chan articles belong there?

Lesson to be learned:

Wisdom and knowledge do not come from technology. They come from wise and experienced educators working one-on-one with their students, not to tell them the truth, but to help them experience the truth. Nullius in verba!

Ed-tech is confidence game.

What technology offers is the productive capacity to support a world filled with actual human educators and actual human intelligence.
>And I feel lately that they are now trying to build a case for some sort of conflict, presumably cold, against Russia.

Russia invaded Ukraine & Crimea, ended up downing a civilian airliner killing them all.

Slaughtered hospital workers in Syria after following victims of regime chemical weapons attack to the facilities.

Has been funneling heavy weapons like T90 tanks into sub-state militias, including the designated terrorist org Hezbollah.

Is currently attacking people who have documented all of this, regardless of what nation they live in. Has attempted to get Canada to take down and expose citizens using their services to publicize Russia's actions.

What will it take to get you to understand Russia is at war with the world? Does another civilian airliner need to be downed? Should another analyst/journalist get kidnapped and brought into Russia to be disappeared?

What is your threshold of acknowledgement here?
We're in agreement that gravity waves and neutrinos are harder to produce and detect.

They are better for long interstellar distance communications because their weakly interacting nature and difficult to produce nature means there is no dispersion relationship to worry about, no absorbtion/attenuation issues to worry about, and no noise sources to worry about. The galaxy is a surprisingly difficult medium to send radio waves through if you want them to be received at great distances (difficult medium, not impossible medium). That's one of the things that led early SETI thinkers like Barney Oliver to propose using the spectral Water Hole[0] as a search target.

Gravity waves and neutrinos are harder to produce and detect but the galaxy itself is much less likely to interfere with their propagation if you can produce and detect them. Also, communications uses of gravity waves would presumably be at much higher frequencies so the detector sizes would be much smaller (the size of an interferometer or Weber bar detector is a function of the center detection frequency of the device... sensitivity is largely independent of the size, other than the choice of center detection frequency).

But that's really an incorrect position for it. The most commonly used keys should be easiest to hit (hence the Command key on Macs being right next to the spacebar). Since Control is used more often then Alt, Control should be immediately next to the spacebar, then Alt, then Function.

But if there are 10,000 to several million of them, then the odds of detecting a signal go up as we look at more stars.

Something came to mind the other day, when someone was on Hacker News in Puerto Rico mentioning how they were leaving (for Atlanta I think)?

What if we just crowdfunded people getting out of PR and helping them get setup in the US? If the US government won't address the humanitarian crisis, yet its still a humanitarian crisis, could we still not address it collectively as private individuals?

When a government turns its back on its citizens, its citizens are left to help their fellow citizens.
