Systemd has a couple of nice features around this: init can open the hardware watchdog and ping it as required, so if init ever stops then the machine will reboot. At the same time, services can be set up to need to write to their own watchdog. So if a service dies, either init will notice and take appropriate action, or init will also have died and the hardware watchdog will reboot the system.

Also -- and this has been useful to me on a laptop -- init will configure the watchdog as a last-resort to kill the system when shutting down.
They're almost gone, aren't they? Damn shame. Just a shame.

Yes, but farmers already start to complain. When a machine breaks down they now have to wait for a specialist to come and fix it.
I'd sure like to hear an explanation for the ethics of publishing this material.

When a company screws up, they need to be able to frankly assess the event. Journalists who publish this kind of content are disrupting the kind of honesty that is necessary for fixing these issues.

What are the motivations of someone who leaks this material? Why is it ok to publish this? Are we learning something new?
You can have a type-safe fluent Builder, but it requires having one or more static nested classes with private constructors. The outer class will not have a build() method, but rather that method will live in one of the nested classes. You use the type system to control what parameters have already been set, and what parameters need to be set.

Obviously, this can apply to many sorts of fluent API. This is at least part of what Tony Morris is alluding to in his essay on API design [1].

Awesome! FWIW, my needs don't require any sort of "relational" concept as some comments have suggested, I just need to be able to do all existing operations on each sheet in the workbook. I guess being able to get a list of the sheets in the workbook might be useful, as well, or get a sheet by name, but for my use case I already know the name.
One guess about what the car could offer: The main issue with current technologies is that they only drive automatically in specific situations - and that they legally require you to always stay alert and don't let you play with your phone , etc. But this is extremely boring , hence hard. So this reduces a lot of the value of half-automated driving.

But let's say we have a fun interesting friend in the car, talking to us whenever we want, but knows when to shut up or to simplify the conversation when the road demands more of our focus.

Suddenly half-automated driving becomes much more valuable. And possibly ,if you control that and have a large customer base with half-automated cars ,you have a very good path to full self driving.

Well, Apple wants Siri to be that friend.

>"You hear a lot about young entrepreneurs who come in with a certain confidence," Fonstad says. "Holmes had 10 times that."

I hear this kind of thing a lot and wonder what specifically they are describing. Is it swagger? Is it how she responded to questions? Is it the traction they had that they could point to? Some combination of all of these?

Seems like a critical thing and never really described what people mean by "confidence." After all one person's confidence is another persons arrogance, so I'd be interested to see how she had 10x confidence without crossing that line.

> I made another comment saying that it was satire (without the douche-iness), and it got downvoted, too. So its just disagreement.

This is kind of superfluous to the discussion but I'm trying to be constructive here, honest: all three of your comments on this story might lead one to believe that you are an enormous bag of douche. Reexamine your use of terms like "common misconception" and "quite clear" as an exercise.

> completely superficial perspective

See, you're doing it again with the douchiness.

I mean, the story links to an interview with a well-respected science fiction author (who has won so many Hugo and Nebula awards that it's like they are shooting them at him with a t-shirt cannon and who also teaches an SF class at MIT discussing Starship Troopers) and he disagrees with you about the book. Do you think he's just being superficial? I mean I guess it's technically possible that he just hasn't thought about the book as much as you have...

Acting as if the people who disagree with you just don't get it is making you look a little silly. That's what the downvotes are about.

I'm not sure which boogeyman you're fighting but since you're talking to me all I can say is that I've never threatened anyone and never would (shouldn't even need to be said).

Honestly, your condescending tone, immaturity and personal attacks are things I can't get on-board with. Being righteously indignant doesn't help you make your case.
If this were the case, chances are very good that this drug wouldn't exist at all. Drug R&D would become politically driven, with earmarks being given by politicians which benefit their constituents rather than actually advancing the state of the art. Public money would be poured into research for drugs which address ailments in the public consciousness, rather than into drugs which may actually have a chance of success.

You really don't want medical science led by popular opinion.
> I strongly dislike such tactics since it causes people to waste a ton of time dealhunting, but isn't this usually to the benefit of the poor? These tactics allow companies to price discriminate and charge the rich more -- since they won't spend the time clipping coupons, waiting inline on black friday, or waiting for sales -- and thus theoretically subsidizes the 'discounted' prices for the poor.

Even without ericglyman's link to corroborating data, I would assume it goes the other way. Coupon-clipping and online deal-hunting requires time and, especially, emotional energy that the poor often don't have; and since the poor generally have to use essential items until they physically fail, and then scrabble frantically for the first available half-decent replacement, they don't have the luxury of waiting for special sales.
Some people, such as myself, dislike the movie because it was an almost completely unrelated script that was just reworked to have some of the same superficial elements as the book.

It wasn't satirizing anything. It was just capitalizing on name recognition.

But if they didn't do that, fewer people would have watched it, and we would not now be discussing movie vs. book, because they would have always been two separate things. They still are, really.

When I read the book, I didn't see it as either pro-military or anti-military. It was a fictionalization of actual contemporary military experiences into a future sci-fi setting. The reaction should be in the eye of the beholder. The book may have seemed to glorify the military, because the entire premise of the book was that the military had essentially staged a coup against every human government, this making it the keystone of all human society. The rest is just how Heinlein thought things would work if the military were in charge of everything. Some things would work better; some would be worse.
If you can stand anime, find an old series called "Legend of the Galactic Heroes". It's long, it's decently hard sci-fi in places, and it's got wonderful reflections on war and politics.

It very much feels like old Pournelle/Heinlen stuff, with a healthy amount of cynicism about the politicians causing the various conflicts.

On the surface, it's just Space America versus Space Prussia, but there's so much more going on.
Interesting side note: one of the most successful altcoins (a few years ago, back when people cared about this stuff) was called litecoin. The major difference is that it used scrypt instead of SHA because it was hard to parallelize. The idea was this would keep rich groups from taking over the network by throwing money at hashing clusters.

I built a machine in a milk crate that had 5xR9s to mine it. I broke even and sold it after I got bored :) It was fun for a month or two.
I had similar thoughts, but there's still plenty of low-hanging fruit for Apple to snap up human-driven car marketshare even if it isn't a growing market. By the time they might plateau, they'll have experience under their belt as they adjust to a fleet model.

And Apple is not purely consumer-oriented, of course. If they can work with IBM, they can work with any company that wants a fleet.
I'd recommend listening to this podcast from Horace Dediu about how apple can differentiate themselves.

Fair enough, Tesla would have been a better benchmark.

I wanted to point out the huge R&D effort a car company has to undertake even to stay relevant. We are not even talking about the amount of innovation Apple or Tesla are expected to bring to the table.

Another difference between Tesla and Apple is that Tesla has strong partners in the traditional auto industry, namely Toyota and Daimler.

How to display threaded discussions on the web
I really like the 2chan style, it's simple and nostalgia-inducing. The 4chan modernisations such as the thread title in the URL, the removal of the e-mail field, the re-numbering of pages starting from 0 to 1.

It would be much nicer if they could put on a version of Futallaby with a modification for image replies (I believe Saguaro does this) or use Wakaba (much more featured, but using Perl).
They're a CLIA certified lab so they don't need to publish public peer reviewed studies. They're also slowly submitting their tests to FDA, which isn't required for their kinda lab (something Quest & others actively are fighting).

Quest and others don't really have peer-reviewed studies for their tests.
>This seems like a weird market for Apple to be pursuing because they’re such a consumer oriented company, but it seems likely that the future of transportation will be less oriented around individual car ownership.

Apple is a company that wants to make money. They'd go into turkey farming if they thought they could make more money there than in phones.

If individual ownership is on the out (it isn't imho and that is a totally separate question from driverless tech) then apple wants to be the company that owns/leases/copyrights/patents the cars, the software and absolutely everything else. Dominance of specific markets is apple's game.

There is a synergy between apple's customer base and driveless tech. Apple owners are generally early adopters with cash to spend on fashion items. As with any new tech, the first few iterations of any driverless car scheme will be short-lived and expensive. Apple knows that its fashion-chasing users will be all over these things. Requiring "drivers" to control cars via iPhones would just be gravy.
That's not how you keep 50% of a company. It's usually cash off the table or keeping your equity.
I would too, except that the article tries very hard to not mention "Embraer". Instead, it lists the manufacturer as being "Sierra Nevada Corporation".
Automated tractor is not as complex as automated car since the environment is much simpler. I think it's closer to iRobot Roomba rather than self driving car.
Car manufactures have figured out a "universal interface" (buttons) as much as iPhone figured out touch screen.

There is nothing universal about the iphone interaction except that you touch it, for example it doesn't have a back button which most other manufactures do. Behind that touch screen you have the same mess of buttons/sliders/dropdowns/checkboxes/toggles between different models, as in cars.

In my experience a lot of firms don't necessarily want direct support - but they may want an SLA.

The nature of the open source market has changed, and I've found that most people conflate free as in speech with free as in beer. As a result, people are picking up open source projects specifically because there's no cost involved, making support - or any kind of license or subscription - a very tough sell.

The only predictable way of selling services on top of an open project I've found has been to hold a piece back and make it commercial, which I think cuts against the principle of the thing. Nonetheless, eating and paying rent are important, so that's the way it goes.

One-off customizations are another matter, but the expectation is that because you gave away your code to begin with, you're going to work for a below-market hourly rate.

Disclosure: I've cofounded two end-user open source projects (elgg.org and withknown.com). At this point I could not be more jaded. It's possible the dynamics are different for infrastructure projects, but the state of OpenSSL et al suggest not.
No, it is the mis-allocation of capital.

There are so many bridges, highways which need to be fixed. There is so much trash in cities which could be picked up from the streets. There are so many older people who need/will need care.

There is no money to pay for all this.

But there is money sloshing around, buying $50M apartments in New York City, etc.
Staying true to your username, I applaud you.
Moving matter rather than information is inherently expensive. A lot of the current darlings are about moving matter around. Their best bet is to achieve monopolistic dominance by being radically more cost-efficient than the old-school industries they disrupt, but it's still expensive.

The number of companies that have bad unit economics is, I agree, substantially higher than it should be. But I'm not sure this explains the bubblegum expansion of valuations and rounds we're seeing today. There are many thoughtful comments on the perceived bubble from people all over the industry. I'm not qualified to say one way or the other, but I did enjoy Mark Cuban's recent post on the matter. [1]

My company, Thumbtack, got a lot of this right early on. Years ago we doubled down on getting the unit economics right. So right that we were (IIRC) profitable for a month or two before taking a big VC round. Not sure how many other companies can say that. But at the end of the day, if the bubble is a bubble and it pops, knowing that we would survive and be able to make a profit is hugely satisfying.

My advice to any young startup is figure out how to make money early on. It's the rare Google/Facebook that can blow up and use the platform to sell ads. Most startups will not do this, but many can still make good money doing important things that people will pay for.

How the Sexes Fundraise

15 Percent of U.S. venture funding goes to startup teams that include a woman, and only 2.7 percent of venture funding goes to female CEOs.

3x Male founders are that much more likely to find equity financing through angels than their female counterparts.

14 Percent of men tap business acquaintances, versus 5 percent of women.

2 Percent of women are likely to leverage networks of close friends, as opposed to 9 percent of men.

I like seeing these stats included, but I wish there was more context than just gender. I was one of the top three students of my graduating HS class and some people expected me to be a millionaire by age 30, but I did the full time wife and mom thing instead. I have done a fair bit of reading over the years to try to understand why I never got the two career couple lifestyle I had been "told" by society/media was my due. The exact mechanics of how and why women do this differently is far more interesting and useful information than dry stats.

America is one of few advanced nations that allow direct advertising of prescription drugs.

To quote some comedian's take on this, 'in my country, your doctor tells you which drugs he wants to prescribe. In America, it's the other way around.' It's astonishing to me that direct-to-consumer pharmaceutical advertising is so rampant here, when somehow we managed to eliminate this for tobacco advertising without causing the 1st amendment to self-destruct. Besides the first-order consequences of medically ignorant consumers besieging their doctors with requests from drugs they can't even pronounce properly, it's also created this bizarre culture where illness is normative and every medical condition has to have a cute nickname or acronym - it can't be long before we start seeing people break up in soap operas because 'I love you...but my hep C isn't compatible with your A-fib!'

My thoughts exactly. It seems to me that many of the problems in the health care system stem from the fact that there are soo many convoluted regulations that it's impossible to enter and compete in that market. And in many cases, people get in there and completely take advantage of the situation.

I only use Windows 10 in a VM for browser testing but I just disable the Windows Update service. I have a PowerShell script which can enable it, hang around and disable it again later which I use when I want to do updates, i.e. when I'm not busy focusing on a task.

I guess it will slightly reduce the overall security but as I only use it as a VM and am generally testing locally its an acceptable trade off in my opinion. The reason I set it up this way was to avoid the time sinks that come from when I do use Windows and then have to wait an age for updates to be done when I'm focusing on work. Previously I always used the option to be notified about updates rather than auto install which was a reasonable trade off. I understand why Microsoft made the change but I strongly disagree with it.

Ask HN: Which email marketing software should I use?
I run a mobile app company and I've decided to start collecting emails for cross promotion of my apps. I've used mailchimp in the past, and I have no issues with it, but I will likely be passing their free tier soon so I thought I should do some more research. I perfectly happy with suggestions that say, put your credit card into mailchimp and be done with it, if that's my best option

Generally speaking, I would hope/expect to have a bigger list that I send to 1-2 times a month at most. (as opposed to a smaller list that I emailed a couple times a week or something)

Price is likely the main factor, but ease of use is also key. I don't want to spend a ton of time coding my own X for this. Just get in, type out email, hit send. Autoresponders would be a bonus as well.

What would you use at X list size where X = :

25k?
500k?
5 mil?

Thanks so much.
