This article misses an actual definition of Big O.

This forces us to skip crucial points like why O(n^2) truly identically equals O(n^2/2 + 5n). The author instead seems to think they are approximately the same because the lower order terms are small compared to the highest one.

We only need to explain the definition and the reader could understand why an O(n) algorithm is in O(n^2), why some O(n^3) algorithms are much faster than others in O(n^~2.4), etc.
It supports a 'quake mode', which is the only reason I use it.

Soil salinity is a serious issue in the central valley of California [1]. Converting more of that land (often currently fallow) to solar is an interesting solution to the problem.

That's not what i meant. I am mainly shocked at the publics general failure to understand human nature and its desire to extract money when incentivized to do so. I dont disagree that wind can have a lower footprint in terms of landspace taken but if solar is more efficient and less expensive then at some point when it becomes long enough lasting to be profitable, then of course those with forests will convert them to solar farms. This was not unforeseeable
(if a b c) translates to, for instance in Common Lisp, (cond (a b) (t c)): four more parentheses and an extra symbol.

cond came first; if was invented later for less verbiage in the common case of testing a single condition, where the consequent and alternative are single expressions.

cond is better than if when you find yourself stuffing progn bodies into the if. (if a (progn b c) (progn d e)) -> (cond (a b c) (t d e)).

No; a lot of wires carry the actual power to the effector (e.g. a lam, or a motor, or a relay). WiFi, on top of being vastly more complex, has issues with electromagnetic noise, wave propagation problems, and thus delivery delays. And it needs a processor powerful enough to run all the logic with encryption on top, because you don't want strangers to talk to your devices.

I've seen a couple of comments here talking about feature flags and I don't think that's quite what Carmack is getting at here.

It seems he's talking more about refactoring/optimizing/debugging working code rather than adding new features. Then the old version of the code becomes a point of reference against which you test your new implementation.

Once you are very confident that your new implementation is no worse than the old implementation you have two choices.

1. Leave your old implementation around as a reference implementation, but mainly use your new implementation. This is useful if your old implementation is functional and readable but slow and your new implementation is less readable but faster. This helps other developers understand your new implementation.

2. Remove your old implementation altogether and just keep your new implementation in your codebase.

Either way the thing Carmack is advocating for is having an extended period of time where the two implementations coexist, even though one of the implementations is "redundant." He is explicitly advocating this despite the fact that you could in theory just retrieve the redundant implementation from version control and not have to "pollute" your codebase with a redundant implementation.
Is the human allowed to use pencil & paper when reasoning about the stock? A graphing calculator? A spreadsheet program? A numerical SDE solver?

As others mentioned, I'm primarily interested in noticing the extension gaining malicious code, such as often occurs in the wake of a transfer, not noticing the transfer itself. (Which would also capture the case of extension not actually changing hands but nonetheless shipping malicious code - including both your example as well as a targeted attack on an ethical developer.)

Also I think it's reasonable for browsers to require complete auditable source (even if there's some obfuscation happening before it gets to users), which would probably have a deterrent effect on weakly-ethical developers - it's harder to ship code you can plainly see is malicious than to just sell the extension and wipe your hands of it. (There are enough stories of founders who care about their companies selling startups to acquirers that don't that I think there is something in human nature that makes it easier to hand off your creation to someone who will do bad things with it than to do the same bad things yourself.)
Takeaways from Attending College Tuition-Free for Six and a Half Years
I'm not sure why you're getting downvoted. The valuation of quite a number of hot companies doesn't make any sense unless they can extract oligopoly rents.

As an example, take Uber. The Economist recently asked whether it can ever make money. [1] And events in the months since don't make it any clearer. [2]

I think tech's wave of quasi-monopolies (Google, Facebook, Amazon) gave investors the notion that similarly dominant players could be established in non-tech fields if they were dressed up as technology plays. So we see absurd amounts of cash being poured into things like Uber and WeWork. Unlike the previous players, we also see them going to IPO while they're still losing money.

And sadly, I think you're right about regulatory laxness. Antitrust regulation has been out of fashion for a long time. And if we see it come back, it could well be more an authoritarian political tool than any actual attempt to ensure competitive markets.

I'm unsure it's that simple, since none of those policies are recent enough to explain why housing starts have been below the historical trend for ten years.

Excessively low property taxes in California likely doesn't help, but doesn't explain the high prices in other coastal cities.

It doesn't seem optimal to put them in a circular formation like that, though. From wherever the sun hits, some panels will be hit from the side and the light will miss the panel completely. It looks cool, but it doesn't seem realistic.
I'm more a fan of the inverse: anything that could be reformed in the future should not be proposed without an accompanying explanation of the full context of the decision to enact the policy.

If you believe reforms should not be made, publish those arguments to the best of your abilities.

Never assume that your reasoning will be obvious to even the next person in your position, let alone the next generation.
A diagnosis allows life to finally make sense. Even for those that are able to blend in, it's really great to have a framework to understand things, and that there's a community that actually understands you because they have first-hand experience of eg, the rage and meltdowns that plague individuals with autism.

Post diagnosis, there's even treatment for some of the things that high-end functioning adults with autism simply can't do without medication, and are negatively judged for by society.

>I'm sorry but whatever the official description is, for many people including me, runs on an arduino means runs on an at mega with a bootloader and maybe on some kind of specific board with funny connectors.

Why? The Arduino stack will work on ARM chips - better, cheaper chips than the 328p. Arduino.cc make, sell and officially support ARM boards; there are a huge range of cheap Arduino-compatible boards with modern microcontrollers. The cheapest M4 chips are priced competitively with the 328p and M0 chips are available for as little as $0.24 in quantity.

The 328 is an ancient, inefficient, overpriced chip and I see absolutely no reason to endure it any longer.

Not the floating point, but saw his code for other parts of the 6502 Apple products, he really was a genius. The code is both very clever AND quite understandable.

My understanding is his circuit design was similar. One thing, use a part of the circuit for two different things at different points of the clock cycles, so parts count was reduced.

> In the document, Domino’s lays out its argument, claiming the cost of accessibility requirements may run into the millions, and the rules around what is accessible and what is not have yet to be decided.

This is a dense argument. There are well-established web content accessibility guidelines, aptly named Web Content Accessibility Guidelines. Android has accessibility features built-in, and I'd guess iOS does too, despite having never used it myself. Nothing about this is particularly costly. WCAG has been around for over a decade...so what is Domino's angle, really? For a company that seems to embrace tech, this makes no sense.
Love the codebase, I never wrote any Kotlin (and very little Java) and was able to (hopefully) complete a good first issue very quickly.
If anything this stuff helps real crooks like Epstein by muddying the water and making the whole subject area look silly. I sometimes wonder if some of it is intentional. Seems like a great way to cover things up in an age where actually keeping secrets is hard.

I know if I were running a human trafficking, prostitution, and blackmail operation and wanted to cover it up I'd start by spreading wild theories and false accusations about elite Satanic cartoon villain cults doing exactly what I'm doing. That way the whole topic would get an aura of crankiness and reputable media would stay away.

Disinformation is like radar chaff. You just blow out a lot of noise and nobody knows where the signal is. The real secrets might leak but it doesn't matter because they just merge and blend in with all the bullshit.

A grassroots explanation for this stuff is more likely of course, if only for Ockham's razor reasons. My point is that no good is accomplished by spreading nonsense.

That's true, although to be fair, there's only so much a delivery driver can do service-wise compared to a waiter. Your only interaction with the driver is picking up the order. The driver isn't responsible for the time the restaurant takes to get the food to them, and isn't even entirely responsible for the time it takes to get the food from the restaurant to you -- there's traffic, weather, and the possibility that DoorDash demands they batch orders (something I've heard but haven't confirmed). I'm not sure it's fair to hold a third-party delivery driver responsible for the correctness of the order, either, rather than the restaurant.
...except the most rural counties.

This may come as a surprise, but I live in a rural county, and the house we're talking about is in an even more rural county. It's curious, that on HN we Americans are always reminded not to assume anything about other cultures (and rightly so), but we're eager in turn to assume all sorts of things about other states we've never seen. You've got some strong emotions about how remodeling should be done and paid for, but not everyone feels the same as you do. Certainly not everyone felt that way decades before you even thought about construction. California (or whatever other state you're referencing) is not a microcosm of the rest of the nation.

Anyway, you're wrong about that state too. Lots of remodeling gets done there, too, without the involvement of licensed general contractors.

European windows open on hinges, they don't slide.

This makes it hard to install such an unit and keeping the window airtight. It's also hard to get agreement from landlords (most people rent), so many people get portable units that blow hot exhaust air out via a dryer-vent style hose. That get stuck out the window, and the window is poorly air-tightened using a velroed-on barrier. The advantage is that it requires zero "modifications" and thus you can just do it.

The downside is that they're horribly inefficient.

> Nanosecond pricing updates might be a little more than anybody needs

That may be the case, but the 'problem' is caused because market makers aren't legally allowed to offer better prices than they might otherwise desire. It doesn't seem prudent to layer flawed regulation on top of flawed regulation when there's a simpler solution.

> Remember the market is ultimately about allocating capital between businesses and governments

Equity markets have many purposes. Companies indeed raise money by issuing equity (IPOs and secondaries), and there are cases where governments participate for monetary purposes (BoJ & SNB's equity purchases). But markets also allow:

* employees to sell equity compensation they've received whenever they want

* retail investors to diversify their asset allocations

* sovereign wealth funds, pension funds, endowments, and other real money sources return on their portfolios

* for hedging financial risks

* companies to return money to shareholders in the form of buy backs

> for economic purposes it doesn't need to run any faster than they can

All the previously mentioned functions happen all the time, and the marks (prices) generated from this activity helps inform many other economic functions. Everything from central bank policy to insurance pricing depends on well functioning markets. In light of this, why should we make things less efficient by slowing things down and driving the cost up?
Those are concentration mirror, they reflect light onto the spire in the middle which had a receiving element at the top. Conventially they're used for thermal application where you use the sun to generate steam at the top of the tower, although there has been research into beam down variants where the light is reflected down to a very high efficiency PV cell.
The "free choice" argument is a charade: the only people with the "freedom" (ie, wealth) to win that race are "people" like Goldman Sachs. On the whole, it's just another legal mechanism for pumping money from the poor to the wealthy. Modern markets could not exist without regulation, which by definition limits freedoms. We're just talking about a sensible regulation that eliminates a pointless misdirection of resources, not unlike laws against gambling.
> There was ~$107 billion in online advertising in 2018. There was ~$145 billion traded in Nasdaq listed equities yesterday.
