Hard-boiling an egg is trivial. Soft-boiling an egg, or making a perfect poached egg, is non-trivial; it's a finesse task. And doing it once or twice is one thing, but plating 10-20 for a bunch is another.

Also: your definition of "a perfect steak" is different from mine. You either like a little overcooked steak or a little undercooked steak (or maybe a lot of either), because you can't get uniform doneness in a cast-iron skillet and an oven.
I live near a twin-lake hydro system that does just that.

Yes, I do think that. Hard-boiled eggs are gross. Set egg yolks are gross. An egg white that is even slightly undercooked is also disgusting. There's a relatively narrow band of doneness in which eggs are good. You sound less like an advocate of simplicity and more like, as Dave Arnold would put it, "an enemy of quality". :)
This is interesting. I've assumed ride-sharing services would benefit self-driving cars, but the thought that individuals could own cars and rent them out in an AirBnB like manner is something I hadn't considered. That's very cool, considering that today cars are a pretty poor investment.
It is! And I wish more sites would make it accessible like it used to be by just going to m.domain.tld rather than user-agent sniffing, because I often prefer the simpler mobile version I get when I spoof my user agent from the desktop.
You're the first person who (a) evidently cooks a lot and (b) has a water bath setup that I've ever seen call it "impractical". It is vastly more practical than a smart frying pan; among other things, it cooks unattended, the same way a crock pot does.
There are some secondary advantages to sous-vide prep, like being able to hold the finished steak at temperature until you're ready to serve.
I think it's more likely we'll see an asteroid mining economy bringing lithium for batteries on Earth than millions of 1km holes with 20 ton weights storing energy for single charges of electric vehicles.

Whatever local (i.e. small scale) energy storage we have in the future you can probably bet (from first principles) with 99% certainty it will be based on the electromagnetic force. Gravity is too weak to be practical for smaller scale storage and cannot give mobile storage units since you have to deal with huge weights. For large scale see the "pumped storage" system already mentioned in this thread. Just for illustration, the "Taum Sauk Hydroelectric Power Station" can produce 175MW of continuous power. If you dropped the 18T weight in the 1km shaft you'd get about 13MW averaged over the 14s fall. Then you have to lift it up again if there are still enough pieces left.

Even if you found a way to store energy in nuclear interactions (i.e. "charge a nuclear battery") you don't want to have a bunch of containers full of radioactive material all over the place. If one thought it through, I wouldn't be surprised if there are in-principle issues for the charging part similar to the ones with gravity.

Since we don't know of any others, this leaves only the electromagnetic force to store energy with sufficient mass (or volume) density in practical ways. Whatever it ends up being (chemical batteries, supercapacitors or something else) the future local energy storage unit will separate and hold charges apart.
Not really. Electrical engines and generators are incredibly efficient. It's not the transition there that is the problem. In fact, if it was only for that loss the efficiency would be more like 97%. The problem is the friction in the mechanical parts; the wires, gears and so on.

Often, when people talk of Jobs' reality distortion field, they refer to how he made you feel when you were in the same room as him, and he was talking to you. About how even if what he was asking seemed impossible from a technical point of view, as an engineer or designer or manager you couldn't say no to him, and in the end ended up being swayed by his arguments. Or how no matter what your intentions were, he'd be able to change your mind (e.g. http://www.folklore.org/StoryView.py?story=Are_You_Gonna_Do_...). The media has then completely changed the meaning of "reality distortion field" to turn it into a self fulfilling prophecy of sorts - "Steve said it and we're convinced because he has the reality distortion field". But in that case, we're just watching a video of a keynote - there is no "reality distortion field, and thus he has a reality distortion field". As humans, we like being convinced and believing in fantastic, out-of-this-workld things - the latter form of the RDF is solely in the eye of the beholder.

I've never worked with Elon Musk nor do I know anyone who has, so who knows if he does have a proper RDF the way Steve did. But he definitely has a form of the latter - subconsciously, we want to see heroes conquering space just by the might of their hard work, smarts, and determination, and Elon is the perfect person to project that on to. Hence why journalists write glorious introductions like the one above without anyone having to ask them to.

because like many things, programming hours and talent have been commoditized.

True. We should have fought it. We should still be fighting it. If commoditization is doomed to happen, then there's a structure (called a union) that enables it to happen on our terms rather than theirs.
This is neat, but not novel. I used to live in a house (UK, middle of nowhere) that had a deep borehole that was used for this purpose 130 years ago. The weight and winding were long gone, but the dynamo was still sat there. Oh, and it wasn't raised by water, rather, servants, back in the day.
IMO "griefer" has a pretty defined meaning and implies a player who is going out of their way to be a jerk and, well, cause grief.

I'll agree that "looter" could be understood to be a scavenger and not an inherently anti-social player.

So if you just said looter I'd agree with you. When you say griefer I don't - IMO a griefer is inherently a jerk (player, not character)

As I addressed in the other comment, yes, indeed, this is a technique built for traffic spikes. It is not a technique made for cooking breakfast.

As to steak, just to be clear (since there seems to be a lot of misinformation in here), the best New York City steakhouses grill steaks in a 1800 degree broiler. This is a heat that is difficult to obtain at home, so the sear+oven actually yields a wonderful, very uniform doneness. I suspect you've never tried it, have zero experience with it, but nonetheless pass judgment on it? Why is that?

As someone who has eaten the most expensive steaks, at the most expensive steak houses in the world, I think it's quite fantastic. I guess I defer to your judgment though?
Ask HN: Where to find short deadline, senior-ish, “emergency” gigs?
There are plenty of places to find full-time jobs, contracts, internships, and so on.

Where, though, do people post when they have a same-day (or at least same-week), urgent need?

We (a little team of friends) really enjoy cranking a few all-nighters and helping people hit their deadlines. Sometimes people have a great codebase but aren't ready to figure out how to deploy it. Sometimes people are already in production but they have bugs that they can't nail down.

Are there gigs around like this?
A "six minute egg" has been a benchmark for literally centuries. Apologies if there is confusion, but when I say "hard boiled", I mean all doneness levels of boiled eggs.
It's even worse because you might code up a storm and not add any value. You might work a dead project and only loose the company money.

Very true. We have the value-add potential that, on paper, would justify upward of $700,000 per year. Unfortunately, most of us are managed ineptly and so much of that value is squandered. There are plenty of ways that the surplus generated by our talents could be spent (expansion, higher salaries) but right now it's wasted on a high tolerance for mismanagement.

Actually, they had been generating ~weekly snapshots of built binary packages in the past, but for some reason I don't understand, they weren't used by default, and the setup to actually use them was... obscure and not really officially documented. You had to set the right environment variable to point to the remote HTTP repository.

The new pkg uses the up-to-date repository by default. It has fixed all this mess, and turned binary packages from something very clunky that nobody really used to something fairly solid that can be used in production. The only reason I use ports nowadays is when I need to set custom build options on a package.
In the far future we'll see the inside of cars the same way we see the waiting room at a restaurant or doctor's office. A common place that we all don't mind sitting in for awhile, but it's really not ours to do with as we please.
More likely is that the government will (via regulations) make it very hard to own cars. There are downsides to self-driving car though. Eventually you will have to give up anonymity and the freedom to go where you want, when you want. The government will surely "own" the system that runs the self-driving cars network. Self-driving cars aren't autonomous.
That's what I get for doing intermediate thermo & fluids all day and then trying to make a comment on basic dynamics. Thanks for the catch.
If you have a rice cooker, you can make some incredible fall off the bone slow-cooked ribs.

Or, alternatively, you could pump all that money into the Caltrain electrification project which runs roughly along the same route between the exact same destinations.

I do, however think a road diet on El Camino would be nice. As someone who lives within 2 blocks, it's really unpleasant to have cross 84'+ of asphalt to get to the other side of the street. 10' traffic lanes and separated bike lanes would go a long way to making it more livable.
I use a Sansaire, but have found that for "nice meat" I actually prefer a regular cooking in a grill pan to a perfect-all-through plus just seared. Not sure why, but it's likely something with the gradient of doneness that is a more interesting texture.

Where the sous vide shines I think is for cheap cuts such as pork belly or tougher game meat where you just can't simply sear until done but actually have to break down the meat overnight at target temp. Another perfect use is charcoal grilling for many people. Just throw a huge steak in the sous vide in the morning. Throw it on charcoal when guests arrive just for the flavor.

Driveways are such an American luxury! There are many places in the world that lack these. One reason I don't own a car in Beijing...where would I park the damn thing? A parking space is a comparable expense to my apartment rent.

The real value of self driving cars is (a) optimizing road bandwidth and (b) getting rid of the need for parking everywhere. I can't imagine people owning their own cars as densities increase (which invariably will happen, even in the states), especially if they don't need to.

This looks like a great idea! Ideally though, with electric hobs, I'd like to be able to set the temperature on the hob and then have the pan kept at the correct temperature automatically(with the thermometer still in the pan not the hob).
I suspect there will be classes. I.e. "first class" cars akin to Mercedes/Lexus/BMW which would have a different kind of clientele. And, probably, penalties or expulsion for damaging or soiling the interior.
The author dismisses feature detection as being "slow", but it's much less error prone:

http://www.stucox.com/blog/using-webp-with-modernizr/

You can just cache the result in localStorage; you take a few-millisecond hit once.

Here's how the feature detection is done:

https://github.com/Modernizr/Modernizr/blob/924c7611c170ef2d...

HOWEVER, in this case (webp), it's likely better to detect it on the server:

"I think that caches work where you have a vast imbalance of requests for a particular bit of content - they seem to me to define centralization."

Hu? Caches for geographical distribution are actually a form of decentralization! The problem with the existing ones is that they are mostly under centralized control, but there is no technical reason why that has to be, and an ISP's caching web proxy (which weren't that uncommon back in the day) is a simple example of caching infrastructure under decentralized control that could help an ISP reducing the load on their upstream connection for often-requested content. You don't need youtube to copy a video from your machine to the cache at some viewer's ISP, that's just the way it is commonly done right now because in that way youtube can make money - or, if you want to decentralize further, you could copy to a cache on the machine of some customer of said ISP in some geographic region: The more requests there are for some content, the more likely it is that there is a copy in your neighbourhood that doesn't need to be transferred from the original source.

I'm really excited about this aspect of self-driving cars.

In the future, one day a father may need to schedule a doctor's appointment for his son. He will schedule it after his son's school, and a self-driving car will pick up his son in the pick-up loop (just like how he's dropped off in the morning). Dad will also schedule a self-driving car to meet his son at the doctor. He will receive notifications and photo/video of the pick-up of his son at the school. They will arrive at the doctor's office at the same time.

There's way more things that will change, but I think family planning and dynamics around travel will be one of them.
Well this is true except for what happened last week: Rare occurrences can disrupt the train. Oh well, I'll still commute via train/bus. I don't miss commuting by car.
You're certainly losing torque with the gearing but that's not a problem. The problem is losing energy. Energy loss can be made arbitrarily small at increasing cost to build the transmission.

Many governments already make it hard to own cars: Beijing as a lottery for the privileged of owning a car, given the traffic problems we have here (too many cars, not enough road, horrible smog). But I think I'm OK with that, it is necessary.

Self driving cars could be autonomous, unless you believe that technology freezes in time from today and won't get better in the future. But the main value of self driving cars is optimizing road bandwidth, especially in dense cities like the one I live in, and it makes sense that they would be coordinated rather closely.

It is unclear that the government would own the cars themselves though...just like governments often don't own taxi companies.
I think the original analogy refutes itself. If a strange cat enters your house, you remove it. Likewise, the human body has plenty of methods for regulating fats, sugars, sodium, etc. Of course, you can overwhelm those regulatory methods, but in general the assumption that there's a linear relationship between what you consume and the chronic levels seems pretty naive.

Superb timing as I'm just now implementing some web services in Go and using http.Handler compatible middlewares.

As an alternative there is also Alice[1] but I don't like it's implementation style. Coming from JS and using connect / express what I'd really like is something more like this:

func helloWorld() http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("Hello world!"))
})
}

func main() {

// Wrap the app in Middleware
app := SomeMiddlewareLibrary(helloWorld)

// Run the middleware in this order
app.Use(app.Logger("HELLO-WORLD"))
app.Use(app.CORS("*"))
app.Use(app.Delay("1s"))

// Give the app up to be served
http.ListenAndServe(":8080", app)

During the War of 1812, word reached the East Coast of the U.S. that there was going to be a battle near New Orleans.

There was a guy who _ran_ all the way from the East Coast to New Orleans. When he got there, the battle was already over, so he ran back.

My point is this: technology is not just making us live happier and healthier lives. It's also beginning to raise a generation who won't be able to self-propel themselves over long distances, whether by foot, horse, car, plane, or whatnot. This is going to have implications for the way cities handle disasters.

I love this tech, but it stands to change the nature of what it means to be human almost as much as the electric light did.

I've always been fascinated with the thought of driveways disappearing from new homes in America once self-driving vehicles take off. Future generations will see garages as a decadent luxury, akin to an indoor swimming pool or a private, on-property tennis court.
That's a good point. Say you fill half the hole with containers of water. Let's assume it's 1km deep. Say we have a circular hole that's 2m across, that should get you W = m * g * d = (3.14 * 1m^2 * 500m * 1000kg/m^3) * 9.8m/s^2 * 500m = 7.7 * 10^9 J or 7,700 MJ? That's a lot higher than the numbers being thrown around here.

I haven't seen the figures for passenger volume, but given you can more easily take your bicycle onto Caltrain than on BRT, my strong preference would be for more frequent train service.
