Sure, you can trivially design a data structure where insert and delete have the same cost. This works if you don’t care about query performance; most people care about query performance a great deal. This was litigated in the marketplace decades ago. Even every open source database rejects designs that produce rubbish query performance. It also does not reflect the real-world distribution of operations between insert and delete — we do a lot more inserts.

The “erase-in-place” operations you mention were common in databases a few decades ago and abandoned because the typical performance was terrible compared to the alternative. I am old enough I even implemented a few. It isn’t like these designs didn’t exist, they were deeply flawed for reasons that apply today.

This has nothing to do with perfection. Database engineers would love if deletes where inexpensive even in the absence of hard delete requirements, as that would make update operations, which people want, dramatically cheaper. But that isn’t the reality. You are essentially re-litigating settled database kernel engineering without understanding why they are designed the way they are.

If you thinking there is “low hanging fruit dragging on the ground” then I encourage you to prove it by designing a useful database kernel that can scale deletes while preserving insert and query performance, the two operations that drive all economics in databases. You’ll be instantly famous as a computer scientist because there are some nasty theoretical computer science problems in there.
> Why shouldn’t Apple be able to charge developers for their platform when Epic can?

Very few are making the argument that that Apple shouldn't be able to charge developers for the App Store platform - so long as there are other ways to install applications on iOS devices that don't require going through the App Store.

The situation with Epic is different because even though Epic charges for the use of its software platform on PC it does not have the _only_ software platform for game distribution that can run on the PC. Off the top of my head, there is Steam, Origin, Humble, GOG, Battle.net, and XBox Games for PC as well as developers being able to directly distribute their games without using any third party software platform.

Epic and other developers wouldn't have a problem with Apple charging for inclusion on the iOS App Store if there were other ways to install applications that didn't involve jailbreaking the device first - either a first-class-citizen sideloading capability for the end user or the ability for third-party app stores to run on iOS. Apple wouldn't be required include any other app store by default or even advertise that the feature is present if they didn't want to - they can leave all of the marketing and support up to whoever uses that facility.
> Have all the tractable asymptotic problems been solved?

Definitely not. I think it's more that these approaches are viewed as not necessary as numerical approximations (implemented on a computer) are more accurate, often easier, and allow one to consider complications that would be impossible to handle analytically.

Though analytical methods do have major advantages. Computations are made only for special cases. You'll need a lot of computations to see functional dependencies clearly, for instance. If the computations are expensive (and they often are), people are unlikely to do the parametric studies needed to see functional dependencies clearly. Ultimately an analytical expression contains much more information than an array of numbers.
> The police can enforce a law, but at the end of the day, they don't have to keep you safe in any way.

And these same people claim possession of firearms is a public safety issue. Ironic.

> An example is that the police can engage in high-speed pursuits, and if you get run over and die, that's not their problem.

That is patently dishonest. Civil courts have awarded damages for people hit by police during chases.
I did not. Then again, I have trouble believing that a public park would build a stairway that led into the ocean, even during high tide. That said, this is completely observational.
> It is well established that physical distancing limits the spread of virus transmitted via respiratory droplets. If you refute that, I would require significant peer-reviewed literature on your side.

The study you provided does not support your claim that physical distancing works as it is implemented in the US (6 feet of separation).

> We found that the evidence base for current guidelines is sparse, and the available data do not support the 1- to 2-meter (≈3–6 feet) rule of spatial separation. Of 10 studies on horizontal droplet distance, 8 showed droplets travel more than 2 meters (≈6 feet), in some cases up to 8 meters (≈26 feet).

It's also likely Covid is spread by aerosols. There needs to be more research but it is very likely based on the details of superspreader events.
Given the title, that would be quite funny, as RH IdM is actually written in Python and also open source :) [0]

Named parameters along with property promotion allows for a pretty nice “Struct”-like pattern
For this to be effective you'll need:

- Global agreement and partnership, since you need to decrease temperature globally to make a dent

- Convince everyone that injecting aersols into the atmosphere is the only alternative to catastrophic warming (view in contrast to convincing people of the efficacy of vaccines etc.)

Both of these are incredibly challenging undertakings, even without trying to address the issue of continually acidifying oceans.

And yet, sadly I feel like this is the only most realistic option out of them all.
The linked article I found more convincing:

The original article someone could argue “this just shows men make better pitch decks” which is clearly not the case
If we’re all gonna die, might as well let COVID-19 do it’s job and stop social distancing and mask wearing.
I don't mean to be anti-science, I'm just reporting what I saw with my own eyes. And it wasn't just Daytona. I saw a fisherman in Indian River County standing on what had to be 2 foot of beach. Erosion happens, but why is the water so high to even erode it?
The worst is all the other people on the roads and sidewalks that might pay the price for rich people gadgetry and Silicon Valley move fast and kill people.
Fucking hell, I grew up in NW Hills, are those garbage Domain Apts really $2100 for a 1Br? That's absolutely bonkers!

I like visiting Austin, but after spending time in Boston and NYC Austin is flat out boring and self-centered.

It pains me, but for the past 2-3yrs I candidly refer to my home-town as quote "a shittier less cool version of LA that somehow manages to try harder".
It's about expectations. Yes, 10-50 Mbps is pretty acceptable. Today. It won't be in 5-10 years. 5G will make 1000 Mbps at 1ms, pretty much the expectation, and the apps of tomorrow will need it.

In 10 years people will be talking about 50MBps like they do 3G today. I cannot operate hardly a single app on my phone on 3G. It's worthless in 2020.
Great article.

A tangential benefit: I learned about Taoist breathing practices, and Pol.is.

I also see that the global media is very reluctant to discuss Vietnam's success in handling Covid. I wonder why.
Maybe $1 badass.

But not $500.
What I find most interesting is that we, the Human species, do not know what this means. We estimate heavy losses, maybe near extinction, but we do not have a reference. We are imaginative but we collectively can not imagine the worst and act accordingly. This is perhaps why the worst will actually happen.

I am typing this on a keyboard, when I should be getting out there, convincing others to stop our immediate actions and brace for impact. But I will not do that because some unclear calamity is 30 years away. And I know most people around me will not change anything either.
Reporters report, they don't make shit up. They may occasionally get the details wrong but in general they have a source of some sort that will give them info which they then pass on if it is deemed credible. If the deal wasn't inked and rumored not to be passed then that was newsworthy because everybody expected it to go through. It is very well possible that the reporter was wrong-footed on purpose. Anyway, without any proof to the contrary I'll take his word over yours so unless you want to substantiate with a figure rather than vague suggestions then I suggest we let that stand. Good negotiations on FF behalf and Google's anti-trust woes in Europe could very well get a deal inked at the same level as before.

Finally, and this is reaching, it would be terrible if it ever came out that the reason the Google deal went through is because Mozilla let go of 25% of their employees, specifically the Servo team. Of course that's total speculation on my part but the optics here aren't good at all.

Oh, and thank you for all the hard work on my daily driver.
I'm still trying to figure out why we don't vote via smart phones. Surely there had to be some country in the world doing this?

Vote, take a selfie, photo of an ID and submit or something. Can't be that difficult.
>So it’s over, the planet will likely be rendered uninhabitable probably within the next century.

I'm not sure how you come to that conclusion but the planet won't be uninhabitable. Certain areas will be uninhabitable and there will probably be massive displacement of people paired with food shortages. But complete resignation is not only unhelpful but also unwarranted.
I don't think the amount of work that goes into building a platform is a factor for whether something is monopolistic (in fact, if there's a high barrier of entry it becomes even easier to behave anticompetitively. I'm sure Microsoft spent a lot of time working on Windows and Internet Explorer, but that didn't save them from the Depar of Justice
Uninhabitable? Highly unlikely. Incapable of supporting... checks notes... 7.6 billion people? Probably. I probably wouldn't have chosen to have kids in any universe, but especially as a US citizen, I certainly won't be having kids in this one.
Sorry, done tech support for them, only to find out how slow their internet was.
The fact that we were just saying, as recently as 2016, that things hadn't become "catastrophic" yet, only to four years later make yet another correction that vastly accelerates past existing predictive models is why climate change continues to be seen as debatable. We need to either admit that we don't know or start acting consistently like we do know.

Pushing out an article with a headline like, "Major-global-feature is past the point of return," is not exactly selling the idea of a carbon tax. And the only argument against the critics has been, "Well, it could get even worse!" You mean in 60 days, when we announce something like "China will be underwater by February 2022?" Investments to curb climate change start to look like snake oil when we're saying something can be fixed by it but then announcing 30 days later that it no longer can.
Just reading an article about Japanese Saito surname and how hard the idea of “uni”code (or possibly dropped idea of Hans unification) is problematic in real life situation. Yes you may have a codepoint but it is only part of the problem especially related to human name.

The one thing I wish I could do for people coming into Rust is hand them "Programming Rust" and say "Read this. No, I mean it."

Rust is NOT a Stack Overflow snippet language. Attempting to do so will get you into trouble.

Rust does NOT like pointer magic very much. If you try to be too clever with pointers, you will fight with Rust.

That having been said, I really don't fight with Rust all that much. I don't understand everyone complaining about the borrow checker, but, then, I've been doing embedded C for a very long time now. So, a lot of my bad habits have been ground out of me--quite often very painfully--by chasing subtle bugs in production devices.

After a couple of those experiences, you begin to write very different C code.
How hard is it to turn Servo into a project funded by mass small donations?
Solar/wind needs to be vastly accelerated.

Massive funding of battery, solar, and storage technologies needs to be undertaken.

BEV recharging stations should be incentivized at every gas station with a one-time $50000 tax credit, decreasing $5000/year. Gas stations that do not install them should be subjected to a tax per year starting at $4000/year, increasing $1000/year to $20000/year.

EVs should have an immediate $15,000 tax credit regardless of volume decreasing by $1,500/year.

PHEVs of 80 mile all-electric range should receive a $10,000 tax credit regardless of volume decreasing $1,000/year.

Non-hybrid cars should be subject to a $2,000 tax, increasing $200 per year until it reaches $5,000.

A gasoline carbon tax commensurate with $100/ton of CO2 should be imposed on gasoline, phasing in 25% per year.

Policies as aggressive as these will appear when oil/gas loses its lobbying power, which will accelerate as funding and financing dry up.

Unfortunately, this should have been done decades ago. China is far ahead of the US in funding supply side/production side of BEVs, solar, and wind.
In America, presidents are seen more as king figures than elected officials who are accountable for their actions and can be dismissed easily if they don’t do their jobs like prime ministers are in parliamentary democracies.

One person essentially has sole control of the executive part of the government and the military. It is also very difficult to remove the president from office and essentially impossible unless he does something provably illegal.
We could start by pricing in the negative externalities more accurately.
So the solution must be a ton of bureaucracy, a right to sue VCs when you think there was a gendered element to the decision, HR drones policing every comment by VCs, and affirmative action investments. That will fix everything right up! Oh yeah, and diversity training, including “white fragility” or “toxic masculinity” lectures, which are totally not racist or sexist.

Implicit and systemic bias must be stamped out. If that means bureaucratizing every aspect of life and draining human civilization of dynamism, so be it.

I long for the day when even replies to this post must be approved by a diversity commissar. Give me sterile, enforced equality in a globally homogenous world, or give me death.
Hacker News doesn’t let you edit a comment after a period of time.
I'd be curious to know more about those 15 joins. Why do you think the ORM was doing those ? And what DB are you using ?
> unless you're very rich it'll be beyond your budget anyways

I mean, there's a decent supply of islands (many with houses) that go for barely more than a Bay Area single-family home.
Also, room and board are normally considered auxiliary enterprises, and self-funding. If they have profits, they contribute those to the university, but they are not budgeted with the general campus funds.
And of course, Siberia and Canada will start emitting vast amounts of methane as permafrost thaws.
Beaches are constantly being worn back: the sea advances and the shoreline retreats. Trying to build structures on a beach is a costly battle that cannot be won.
This is hyperbolic. The article was about ice in Greenland, not about the habitability of the planet. Yes, the planet is becoming less hospitable, but we aren't talking about an extension level event for humanity yet.
I'm not sure why this is getting downvoted, but this is a pretty popular perspective in general, let alone VC. Many high-profile folks don't care about your links or secure sites or what have you, they just want the PDF or PPT file.

They also generally want the ability to keep it and show it to others, even if you don't want them to. Classic display of power.
To be clear, I researched popular folks in the "Arduino, control a physical thing that is visually interesting in this space".

I then sent several folks a free sample of a thing, and also rough code, that costs me $100 or so.

And the gamble paid off. One of them ran off with it. It benefitted them pretty much zero as far as I know.

I totally gamed the system. It was not natural in any sense. I got ~3000 sales, and maybe $10k of upside, which was disproportionately in my favor. Most of the magic was this person's fruitful efforts to take my rough idea into something popular. But I like to selfishly think nobody really "lost" in this little microcosm.
Because half the voting base hears the word regulate and starts screaming communism. Just because it would benefit everyone doesn't mean there isn't a huge group of people who would rather cut off their nose to spite their face.
I know a guy who dropped out of HS and did this as an HVAC guy. He bought a house on a lake, a second home at the beach, and built a special garage to house his car collection. After an ugly divorce that cost him almost everything he has rebuilt (but not quite to where he was before). It takes a lot of work but it can be done. As others have observed, it's unfortunately regarded as a low-status option on the coasts
No matter how awful Earth gets from global warming, it’s still going to be many orders of magnitude better than Mars over the next 2 centuries.
Water doesn't have to be high to erode the shore. It'll slowly sink into the water as the lower ground is washed away, regardless of whether the water level is rising.
Yes, the pharmaceutical tech there has decades of experience; one of the first companies I worked for was a Bay Area biotech firm. They moved a big chunk of manufacturing to Puerto Rico and seemed very impressed by the transition. It wasn't just a matter of lower expense. The tech experience in industrial chemistry was very good. Early 1990s.
The answer to why this is, I’m beginning to realize after talking to dozens of Googlers working at Google as acquaintances, friends, former coworkers, HN comments and twitter personalities is - Google has an active disrespect if you’re not part of their in group. If you haven’t passed their tests, you’re basically an object of derision - a mark, an object just used for incrementing a CPM metric, or an incompetent, low-class buffoon who doesn’t deserve to have their jet setting luxury lifestyles. And unfortunately, everything trickles down from that.
> Municipal broadband is a nice idea, but it takes a unique set of circumstances for it to work. Consider how many other municipal infrastructure services are 100% run by your city/county.

Where I live, my electric, water, sewer and gas services are directly run by the city. Trash and recycling are billed through the city but operated by a vendor. They're great. I would love to have internet service through them, and the fact that this town above all hasn't managed to do that is ridiculous.
Uff! I moved to Germany last year and i almost got an account with them... for thor’s beard!!! I’ glad i opened an account at bunq.
Is it possible that the stats are of the flavor (total guns)/(total people) and inflate rural ownership because of a gun for small game, a gun for large game, a gun for self defense, and in certain parts of the country a gun for extremely big fish? Or is gun ownership when computed as (count of people with guns)/(total people) still inflated in rural areas?
Perhaps they think those at risk should exercise some responsibility of their own and quarantine at home?

Is it a human right to have a job, venture to the grocery store, and see friends and family?
In my experience, professors will generally exaggerate the usefulness of the classes they teach. I'm curious as to what things from IR you found useful and what actions it lead you to? I've seen many IR grads who went into it hoping to do some sort of international work or business, only to find that businesses didn't find what they were taught particularly valuable (and the people I met who were sent overseas for business usually didn't have an IR background). Many who that I saw who went into the State Department ended up doing low-level grunt work that was completely detached from the kind of things IR focuses on (and the ambassadors are often wealthy donors with no IR experience who receive the position as a political favor).

Also, many of the things that were covered in IR classes weren't just useless, but more often than not turned out to be entirely detached from reality. For instance, focusing on things like Thomas Huntington vs. Thomas Friedman (neither of who seem to have had a great track record or understanding of the world).
Even if the world is warm enough to melt the sheet completely, that would take centuries, if not millennia; Greenland's ice is thousands of meters thick. In a bad scenario, the IPCC forecasts 21st century sea level rise to be a bit under a meter (https://www.climatecentral.org/news/zeroing-in-on-ipccs-sea-...). This will certainly cause problems, but is nothing like the complete and rapid destruction some pundits describe.

Major action on carbon emissions is long overdue, and it's great that people are taking it more seriously now. But an overly-pessimistic scenario has the same problems as an overly-rosy scenario; if we're all doomed anyway, why do anything? Michael Mann, the climate scientist who famously brought global warming to public attention, now also spends time fighting doom scenarios which also discourage action:

Definitely, American infrastructure is crumbling in big cities. It is really bad. Roads in SF have pot holes everywhere, the whole thing smells. It is awful.

Did you visit Lake Tahoe and any of the National Parks? The country side infrastructure usually is excellent and well maintained.

Certain states are better - Colorado and Utah have excellent roads even in the cities. Phoenix, Arizona is same.
1) Get the White House (and the rest of the state) under non-climate denying control. The USA has to do better - per capita emissions are something like 4 or 5 times worse than the UK (for example). Any form of moral leadership would be nice from the Republican Party would be nice (The Statistics are depressingly split over party lines https://www.pewresearch.org/science/2019/11/25/u-s-public-vi...)

2) Carbon Taxes everywhere

3) Eliminate coal power from the developing world, even if it means switching to gas in the short term.

4) CCS - current efforts already seem surprisingly doable (single digit trillions IIRC)
Yes. This is one of the worst products (most invasive) I have seen. I would hate to be sent a docsend link
You seem to be underestimating the vastness of time throughout the entirety of the universe's existence. There's been far more time in the existence of the universe during which these things didn't happen than the time it took them to happen. If this all measurably happened immediately after the universe's inception, sure, intelligent design seems more likely. But that's simply not the case - the opposite of this all happening is it simply not happening, which was already the case at one point and occupied immensely more time and space before now than that of "existence" as you and I know it.
Was he obese? I only ask because many of the younger patients have comorbities that make them vulnerable to many diseases. And vaccines don't work as well for the obese either.
Gopher. Archie. There was one where you would email a request, it would email back some resource indentifiers, then you would email back the resource you want and back it came. For when your employer allowed email but not open internet.
That's a fair argument. However I'd counter by saying that code is often read in "tool light" environments, such as a diff in an email, code in an online repository, etc.
