My understanding is that the most efficient turbines top out at about 40%. Reciprocating engines are better, but even they can't get much above 50%. There's still lots of heat there even in the most efficient engines.

You're absolutely right about the efficiency being just fine -- especially when you're a pipeline company and you just pull fuel for free out of the pipeline to run the turbine. That's a big reason why these companies haven't built these plants already.

This reminds me of how business types have somehow convinced themselves that the success of franchises like Chipotle is due to "choice", that people really care about choice in fast food nowadays. As if being able to pick from different types of beans was the key differentiator, and not making a popular type of food (not otherwise available at a national chain) and doing it pretty well.

A more interesting, much smaller risk would've been something like a sketch comedy show where every clip is under a minute (Tiktok style). Yeah a ton of amateurs are already doing stuff like that, but - hire them!

I'll agree it's hard to say one way or another since there is no opposite case to test against.

But she was good at setting a vision, expressing that vision, and making sure it was being followed and getting her direct reports to move things in the direction she wanted.

As far as brilliant, I'm referring to raw intelligence. You could tell her new information and she would instantly digest it and apply that to new areas. Also, if you were in a meeting with her once, she'd remember you and what you talked about. If you mentioned that you had kids for example, the next time she saw you months later she'd ask how your kids are, for example.
I never even heard of them before today, and I don't consider myself particularly far out of the loop.
Python and Elixir could not be further from each other. Just for starters, Python is OOP and Elixir is FP, which is a far bigger difference than you seem to imply. Elixir is compiled while Python is interpreted. Python has absolutely incredible community package support while Elixir is much more niche. It's hardly miniscule. It's a completely different way of programming.

I firmly disagree about the value of PEGs (and hence combinators) as a formalism that's ambiguous or hard to reason about. PEGs are as well-specified as CFGs, they just work in a different way. One of the strengths of PEGs is that they're never ambiguous. That does mean that order of alternates is important, and sometimes you do have to fiddle with that order when translating something like ABNF. But what you get in return is never having to deal with a parse forest, let alone punting on that problem by just reifying the greedy parse as the correct one.

I've written a tool that converts a declarative specification of a PEG grammar into a parser, although I haven't released it yet. It works great, I've used it on a number of real-world structured data formats.

For 1: I'm pretty sure the regular firefox containers are an extension of the Facebook container. As I recall, Firefox first rolled out the Facebook container for Facebook + Instagram, and then later rolled out Multi-account containers which allowed user defined rules for custom containers

For 2: I'm not familiar with Chrome profiles, but Firefox has profiles as well. And with Firefox you can set up different container settings for different profiles. So you can have container settings for a "Home" profile and a separate container settings for a "Work" profile
IDEA's K8s plugin validates its YAML. It's stricter than K8S itself though.

K8s will accept a cpu value of 0.1, but the plugin marks it as an error, it wants the millicpu version 100m instead.
I agree with the sibling comment, what you are describing sounds like you are running out of RAM. This happens to me with Firefox on a PC with 64GB of RAM and the cursor gets janky and I have to wait until some poor process gets killed and the PC becomes interactive again and I can restart Firefox.

In my experience LPeg does a good job of being comprehensible for most reasonably-sized use cases. It can even parse the grammar of Lua itself. I've personally had not that much trouble translating BNF grammars to PEG, though the result is typically longer. It still satisfies the goal of separating parsing logic from data logic, which is a big step.

For more info on the issues with PEGs -- and a paper showing how to correctly translate general LL(1p) grammars to PEG -- see:

The thought experiment (based on that ender reference) assumes nobody knows their actions are being mirrored in reality.
Back in my day, when dinosaurs roamed the earth, “weasel words” were “words and phrases aimed at creating an impression that something specific and meaningful has been said, when in fact only a vague or ambiguous claim has been communicated”...so sort of the opposite of the unprovable hyperbole of “everyone knew”. The phraseology isn’t vague or ambiguous, just absurd.

But the American Heritage Dictionary says it also means “a word used to qualify a statement so as to make it potentially misleading“, so the phrase “everybody knew” would count as weasel words. (The phrase “weasel words” has a great etymology that others can look up on their own...)

Many examples of the first definition of weasel words can be found in the British comedies “Yes, Minister” and “Yes, Prime Minister”. E.g.

Sir Humphrey: Unfortunately, although the answer was indeed clear, simple, and straightforward, there is some difficulty in justifiably assigning to it the fourth of the epithets you applied to the statement, inasmuch as the precise correlation between the information you communicated and the facts, insofar as they can be determined and demonstrated, is such as to cause epistemological problems, of sufficient magnitude as to lay upon the logical and semantic resources of the English language a heavier burden than they can reasonably be expected to bear.

Hacker: Epistemological — what are you talking about?

Sir Humphrey: You told a lie.

Came to say this regarding farming as well. On the other hand the number of jobs (skilled and unskilled) caring for the elderly or those with chronic health conditions has probably increased to compensate partially over the last century and will continue to grow. It takes ~2-3 full time laborers (depending on the setting) to care for one person who cannot provide any care for themselves. If the government pays fully for these services, it would not be as extensive as UBI but it would cover a huge number of workers.

It can get even weirder when you jump a gap more than half an octave. For instance say you jump down 6 notes, absolutely speaking it's lower... but relative to the original "note" (not pitch) it's closer to being above than bellow, which can make it feel higher at the same time.

I can perceive this higher+lower aspect simultaneously in a lot of music and i suspect this is common even.

Signs on platforms in NYC are just intentionally obtuse. All the signs on the platforms themselves reference the end of the line bu street name, which nobody knows. Some places name a borough, which is what everyone actually wants to know, but is only ever on the mezzanine levels.
> But is (b) a real problem if you can work on the train?

Japan has the Shinkansen that gets you between the two major cities at 300kmph in slightly less than two hours. Nonetheless, they’re still trying to build a maglev that will do the same thing at 500kmph in 1.1 hours. I guess if you already have the convenience of working on the train, you want to do less of it.

I kind of forgot what my point was.

I think it's clear in the article, but it's worth emphasizing (since it's a pretty brusque phrase) that Ken Thompson stated that it wasn't meant as a claim of superiority, it was meant in the spirit of "this will not be on the test."
The brine in the permeable rock is heated by radiation from the earth's core. It is pumped to surface, power generated, then injected back into the earth at a sufficient distance, so that by the time it flows back to the extraction well it will have been re-heated to the original temperature.

So no, the subsurface will not cool over time (except with some crackpot "technologies" like one mentioned towards the end of the article that rhymes with "never"). It's actually harnessing the radiation of the earth's geology.

There are some places where power is extracted faster than the geology can support. In those cases electrical generation tapers off. This is happening in Turkey for example. But it's because of greed, not because of anything inherent in the technology.

Your claims are unfounded though. The example given in the article, India, is an anomaly. Most countries are very happy with auctions and the results, both financially and coverage-wise. If they weren’t happy, why would they all keep running them? There are dozens of spectrum auctions planned over the next few years around the world, because every country realizes it’s the best way to raise money, the fairest way to distribute spectrum (ie they won’t get sued), and the best for consumers.

Now, is every country perfectly set up for a successful auction? No - but in those cases you’ll see special rules meant to promote competition in the market. New entrants may receive discounts, or certain blocks of bands may be set aside for new entrants only. Big companies may be capped in how much additional spectrum they can purchase is another common case. These auctions are almost never straight up “take what you can get”. You can imagine in the US if that was the case then AT&T and Verizon would own all of it.

My company writes the software for these spectrum auctions, and I’ve personally been a part of dozens of them.

I had this exact problem a while ago when trying to have static types for blog entries. I ended up using a strategy where I would write the config in the language that I would eventually use it in (for my blog, my entries became typescript files).

I think perhaps protobufs (specifically text format protos) are a potentially really nice solution, since you get to leverage the protobuf type system. Unfortunately the support for them is a bit lacking.... (afaik, no formal spec - there’s a canonical implementation in C++; no editor support for things like linting and completions).

I have no idea what direction I am facing

Depends on the borough and the line. My experience is mostly in Manhattan, where subways run (more or less) north/south, or as the MTA calls it uptown/downtown.

In those situations it's very simple to orient yourself from the train.

E.g. I'm going from 42nd street downtown to Astor Place on the IRT Lexington Ave Line (aka the 4 5 6). I get off at Astor Place and I immediately know north/south nee uptown/downtown. The train was heading south! I just need to remember that orientation as I ascend. And because it's a simpler station, it's easy to maintain that orientation as you leave the station.

stand above ground for a while

Yes it can sometimes be very confusing when exiting. They need much clearer indications at every exit. The natives who have been taking the same route for years have no problems, but the tourists can easily get confused.

The solution is simple: paint a compass on the floor near the exits.

This isn't quite so simple. I grew up in Manhattan (many years ago). For the longest time I thought that Manhattan was north/south. Certainly every subway map showed it that way. But it's not. Look at a Google map. Manhattan appears tilted about 20 degrees or so from true north.

The problem would be much worse in other boroughs. Some streets in Brooklyn or Queens are at about 45 degrees from the "cardinal directions" of N E S W. I think compass drawings offset so much from the actual street directions could be very confusing.

I think the newer phones are making this problem easier. Apple seems to have gone out of its way recently to emphasize that its phone is now better at discerning which way it's pointing.
Yeah, I was definitely lucky, I must have caught him in a good mood or maybe he's just really affable. I was super fortunate to have met him though, a class act all the way. He will always be someone that I admire and respect.
That would be better, but that isn't really their complaint.

I hear three main complaints about a variety of sites:

1) The curriculum isn't right for their ages - it is either too cute, made for littler kids, or too much like a lecture, and would be better for older kids. KA tends to trend more towards the lecture side of that spectrum, other sites tend to be too cute. (This is kids from 8-13 giving this feedback.)

2) They dislike the UX. They don't phrase it that way, but they just don't like how they have to interact with questions, videos, etc.

3) Math on KA, specifically, only has one way to teach each topic - if you don't get it, you are out of luck. This is where a tutor would absolutely help.

Content services have thrived or not based on their content library.

So flying directly in the face of that and assuming you could carve out a niche based on a "time of day"/"behavior" thing alone seems very daring, especially when you're still spending an unimaginable amount of $$ on content that you'll need to pay back soon.

The swing and a miss on the consumption model crippled the ability of the content to stand on its own and give them any other chance...
Color me unimpressed. They are essentially "reimplementing" what Instrumental [1] - pioneer of and leader in the manufacturing visual inspection field - has already developed and has been successfully deploying globally. I know that Landing AI is saying that manufacturing is just the first of many potential applications of their platform. However, as of now, it is nothing more than vaporware and I have serious doubts that they plan and/or will be able to build a more general AI platform (as opposed to building multiple industry- or field-specific platforms).

> She's a very good manager when it comes to taking a successful business and making it a lot more successful.

Bit of a leap to conclude that right just based on eBay?

eBay would've had astronomical growth under a dog as CEO. As you mentioned:

> She definitely made eBay much bigger than it would have been without her, but it was already successful and growing when she joined.

And that's her one success story. She's had plenty of other opportunities to demonstrate management competency. I think there's a cognitive fallacy where we assume someone is good because they were there and we lived through things with them.

But as others have said, just look at her wikipedia:

https://en.wikipedia.org/wiki/Meg_Whitman

I think we should challenge ourselves when defending people just because they were there and they didn't fail.

I don't care how brilliant she was at delegating to managers across categories, etc., the world needs space for better leaders than e.g. those who support Prop 8 (were anti-gay marriage) etc. Like if you don't have empathy there, then it's unlikely you're going to be a better manager than, again, my dog.

A manager needs to be a leader. Perhaps she can delegate and she has an MBA from HBS and she's well-connected in Silicon Valley (I remember her connections to Scott Cook at Intuit, etc. - so much bad shit happened under their watch though, poaching, etc.).

But I don't think any of her behavior (unless you have concrete examples) makes her "brilliant" or a "good manager" - unless the standards are pretty out-of-date. We really should not be defending people who don't evolve (and who are financially very taken care of and have every opportunity to earn trust again, but don't).

UPDATE. I see some examples now in the other comments. Personally I'm not convinced. But that's just me.
I've never owned a car but have driven plenty of cars from car shares (Zipcar, etc), rentals, and friends/family. Is it weird that I like the driving experience of a Prius the most out of all the cars I've tried? I've tried multiple Prius models too -- Prius C, standard Prius, and Prius V. They're all pretty good.

Maybe it's because I'm not a car enthusiast. I don't care about acceleration; in fact, I try to minimize acceleration/deceleration when I drive, possibly a habit picked up from bicycling. However, I do care about a smooth ride (even a new Audi I rented stuttered as it shifted gears), and I care about the car not making a ton of noise when I haven't gone onto the road yet. I'd also like to not have to dance between the pedals when going uphill. Hybrid and electric cars categorically do these things well and every single gas car I've driven does not.

Anyway, driving a Prius does not feel the opposite of a "zen like driving experience" to me. I know I'm not a car enthusiast. I'm just surprised that almost everyone here seems to be one.

Sure, you can get users with that model, but you do it if you have content that's compelling enough in spite of it, it doesn't help.
> AWS has probably millions of physical servers by now (they had ca. 1,4 million servers by December 2014 it seems) each with probably hundreds of services each needing an IP.

Why would any significant fraction of these servers require public IPs? And services for that matter.

I wouldn't be surprised if most of them are in private VPCs with only very few endpoints exposed.

If you are referring specifically to AWS, having servers in public subnets is actually an anti-pattern. You may want to do so with bastion hosts and a handful of more specialized services. For everything else, put them behind a load balancer. A single NLB will take one IP per availability zone and will be able to service hundreds of servers, if not more.

Then you have things like Cloudfront and the like.

Not many IPs are needed, overall, compared to the number of actual servers.
