> I, and many others, prefer sysvinit over systemd...

Do you prefer sysvrc over -say- OpenRC, Upstart, runit, etc, etc?
We went through a very similar experience when our car was being transported half way across the country. They driver somehow managed to roll his trailer on a freeway curve (his claim was high winds). His insurance company tried to claim act of god because "the wind did it".

I'm still trying to figure out how the wind pushes over an open trailer with 2 sports cars on it. At least mine was 4 or 5 years old at the time, the other car on there was brand new and had only been driven far enough to get it on and off the trailer.
It accumulates in the body (since it takes decades to go back out), so one-time small exposure is not so bad. Long-term exposure or a very high exposure (like drinking some) on the other hand...
As a sys admin type, I think it's fine. I prefer it over sysV init, upstart, and launchd. There are other options, but I prefer to stick with the more commonly used stuff.

It took a while to get used to, but it does what I need very well (dependency resolution, process supervision, etc).

Sure; I don't mean to deny that such workloads exist. I was a bit sloppy with my writing; I meant for that sentence to illustrate by describing the situation around the product I work on (which isn't OpenGL-oriented, but does involve a lot of things happening in third-party kernel code and other address spaces).
We're talking about hail. Insurance companies cover hail damage all the time.

> not in-line with the unix philosophy of 'do one thing and do it well'

I'm not sure how you could, with a straight face, claim that sysvinit fits this description. It does many things, none of them particularly well.
So if they're adjusting premiums such that they're net positive on every single account, does that mean they'll refund your money if you end the contract without ever having made a claim?
I agree the height restrictions should be more generous, but we shouldn't go to the other extreme. A minimum isn't necessary: property developers will build as much as they think will turn any profit whatsoever. You don't need to force them to try to make money -- just get out of there way!

There's also a downside to minimums: 10-story buildings aren't very cheap to build (unlike 5-story buildings), causing problems if you want new housing stock to target the poor and working class. This makes it challenging to build on the urban fringe where 3-story buildings should be replacing single family homes. 10-story buildings have no business out there, unless maybe you're building next to a transit hub.

You can try to define the "core" part of the city that needs 10-story buildings, but this is more micromanaging than you need to be, and the law will need to keep up with a changing urban landscape. As we've seen in SF and many other US cities, that's a tall order.
We didn't keep continents Europe/Asia free when we populated them. Horses, sheep, wheat, etc to the Americas and Australia were important advances.

I bet when we start populating other worlds, they will become Terran for the simple reason that the ecosystem around us is great for supporting us.
No, that's not how it works.

Transaction volume doesn't increase with efficiency. Blocksize is capped at 1MB, and any new efficiency goes into the hashing algorithms, not the size. The Bitcoin network has always only been able to handle 1 MB of transactions every 10 minutes (~7 tx/s) and always will at this rate.

I think it's like a normal job search really. Be persistent, network, build up your portfolio, and don't be too picky about the gigs you take in the beginning. It took me a few years to get going but now I have more incoming work than I can handle.
This kinda blew up after I left so let me elaborate.

When I say some fields you need formal education in a controlled setting, there's a few examples I can give to provide context.

If you want to go into medicine, you can't borrow a friend and just try things on them. By the time you go into the field any mistake you make becomes critical and it's difficult to log hours and gain experience without a formal educational environment.

To practice law you need to be able to pass the bar, you need to understand decades of case history, legal precedent and how the entire system functions so that you can feasibly operate within that system.

To get into management you can potentially gain experience in volunteer organizations but to do so you're likely going to have enough of a go-getter attitude to be elevated to those positions in the first place. It's not quite the same as saying "I'm going to read these books and learn management."

To go into various fields of engineering there are a number of systems to be understood, sometimes expensive equipment involved and literal danger to other people if things aren't done properly. You can certainly tinker your way into an interest, but you need the formal education in a controlled environment.

There are many other fields that fit within that bubble.

For most of computer science you can pick up and book, sit in front of your laptop and work, learn, experiment, try, fail, learn, improve continuously for virtually no cost other than your own time. You need a goal, then to work towards that goal you learn what you need to accomplish it and pick up those pieces to begin. When it sucks, you learn why and figure out how to improve it. You start optimizing. You need to make something faster you learn how it works under the hood. You need to hook up to some other system you learn about apis. You need to make the interface better, you learn about UX.

The cost to learn is time and that's why this field is constant learning.

I agree with other posters that most people are pursuing advanced math in their spare time. Neither am I but I don't often need to invoke advanced math. I know there are areas where one would need it more, but these days I do not know many people in this field who do.

The crux of my point is simply that, some of the best programmers I know have never gone to college and are 100% self taught. There are very few other fields that you can say that about.

That's all I was getting at.

To the point, the rest of the discussion here revolves around init scripts and the filesystem hierarchy, which are the only parts of LSB that anyone actually used. (And they're sticking around in Debian, at least for now.)

In theory LSB meant a vendor could ship an RPM that would work flawlessly on any Linux distro supporting that LSB release (which on Debian meant supporting RPM alongside DEB as a package format). In practice vendors would just target RHEL and/or Ubuntu and call it a day.

I lived in SF for most of the years between 1992 and 2010, so I saw that a lot of that change first hand. When I first moved there it was a funky, artsy town with a lot of interesting people doing creative things. I was there earlier this year and it now feels like a yuppie playground.

I don't see this trend reversing any time soon though so instead of lamenting this change I'll just live somewhere else if I decide to live in the States again.

"Because of this, I avoid making any claims unless absolutely required."

This is economically efficient behavior - and in fact you should set your deductible to the highest amount you can afford out-of-pocket, as insurance is really only efficient for amounts above that. You should be aiming towards insuring catastrophic loss - eg, a fire that burns your whole house down.
Insurance has got to be the best business to be in. In what other industry is the business model "take people's money and don't do shit"? Plus, in a lot of domains people are required, by law, to get insurance.

It's great.

Except we suck at supporting it. The idea of humanity terraforming another planet are hilarious, we can't run one that was handed to us running and self-sufficient.
It's kind of scary that something of this magnitude would depend on the kindness of the claims inspector. The one I dealt with was professional yet friendly and helpful (and climbed my wooden stepladder while wearing heels without a second thought). If she had been having a bad day, or just generally of grumpy disposition, or whatever, things could easily have gone the other way.
Which would ruin your investment outcome for years (if not decades, depending on the value of your portfolio at the event in question). If stocks take a loss that bad, you need the ability to not sell off to get liquid cash. That is what an emergency fund is for.
They're not - it takes quite a bit of temperature to vaporize (unless nebulized via vacuum cleaner or something) and you gotta be an idiot to eat it... Just clean it up carefully...
Ask HN: What's your personal workflow environment like?
How do you optimize your productivity? What techniques and apps are you using to manage tasks?

I'm especially interested in you super-productive folks who have been sticking with effective routines for a long time (you know who you are, I'm lucky if I can catch you on HN), startup founders and university students. Less interested in those who jump frequently from app to app.

I'll start: I use a variation of GTD techniques for task management (iOS reminders managed by Fantastical), Pomodoro timers for focus (BreakTime on Mac), Productive App for building and tracking my personal habits, HIIT exercises twice weekly for basic physical health, Krill oil omega-3 supplements and probiotics for brain health, Asana for work/group collaboration, pen-and-paper for notes (which are reviewed at the end of the week and digitized with ScanBot) and daily meditation to stay calm and sane.

Would love to hear about your productive environment.
I've been a sysadmin for over a decade, and I love systemd.

The arguments against it appear to be philosophical, not practical, and at no time have I encountered any defect in it. After a brief learning period I came to fully embrace it, and in actual use it makes my life easier in several minor but appreciated ways.

It's understandable that people become used to convention, and are resistant to change. However, most complaints about systemd seem to be appeals to tradition.

> So if they're adjusting premiums such that they're net positive on every single account, does that mean they'll refund your money if you end the contract without ever having made a claim?

No, because you're paying for the peace of mind that comes with knowing that your worst-case scenario has been mitigated, on the off-chance it happens. Even if there is no disaster, you still benefited from not having to worry about it as much (knowing that the insurer would cover some portion of it).

Let's play a game: you're allowed to flip a coin ten times, and I will pay you $1 for each time it comes up heads[0]. Your expected value is $5, but you could make as much as $10 or as little as $0.

Someone else comes up to you and offers to pay you a guaranteed minimum of $2 at the end of the game. In exchange, you have to pay him $.25 every time you flip the coin, regardless of whether it comes up heads or tails.

In expectation, you're going to come out behind, but this game tightens the variance on your outcome. The worst case is that you lose $.50 (you pay the insurer ten quarters, flip ten tails, and receive $2 from the insurer). The best case is that you receive $7.50 (you pay the insurer ten quarters, flip ten heads, and receive $10 from me). The expected outcome is lower, but the range of possible outcomes is $8, not $10.

In the real world, you're insuring against money being taken from you, but mathematically it's the same, and I find it's easier to explain it this way. Most people have a more intuitive sense of earning money than losing it. Go figure - psychology is weird.

[0] One notable difference here is that the distribution of coin flips is approximately normal (binomial), whereas most insured events have a very long tail, with a mode of 0.
Just today I made a suggestion in a Github issue[0] to use sed for a similar use case. There, it was to generate an Amazon ECS task definition file from a CI tool's environment variables. Using this, populating the list of environment variables by looping through the output of env and including anything that matches a given prefix would be a breeze.

Thanks for the excellent tool!

No, it's not that dangerous. Touching it would absorb minuscule amounts into your body, way less than eating contaminated fish, which you can still survive just fine.

Inhaling vapors or mist and eating mercury is the only way to poison yourself. Which doesn't normally happen. But you gotta clean it up meticulously...
A friend of mine has a "mercury blob maze" [1] where you have a little blob of mercury trapped in a plastic container and you have to get it through the maze - it was fun to use at different temperatures, as the blob would want to break apart when hot, or not move at all when cold. Shaking it turns it into 300 blobs.

Upon seeing it, my science teacher dad had some cool stories about playing with Mercury 20-30 years ago in high school classes. They used to take it out and handle it, no big deal :)

Distributed computing "across the planet" only works with low-bandwidth/low-latency tasks. Take a look at the various distributed internet projects (the Great Internet Mersenne Prime Search, Folding@Home, etc) and they are ones that process for a long time and send back a small amount of data, typically to a single server.

People use supercomputers for problems, like weather forecasting, which depend on high-bandwidth, low latency interconnects. For example, the Cray CS-Storm (which the Swiss National Supercomputing Centre will be using) supports "QDR or FDR InfiniBand with Mellanox ConnectX®-3/Connect-IB, or Intel True Scale host channel adapters" (quoting http://www.cray.com/sites/default/files/resources/CrayCS-Sto... ).

To prevent congestion, the supercomputer network topology might even be wired so each pair of neighboring nodes has a dedicated connection.

> miners have made it pretty clear they're not going to adopt it

Source?

Commercial miners make the vast majority of their money on the block reward which has nothing to do with the size of the block. If anything, they'll make more money with less variance with a larger block (since small miners with worse connectivity will have a higher orphan rate).

The only people I've seen opposing a block size increase are idealists who are afraid of further centralization of mining power as hobbyist/small miners will have a more difficult time participating (you'll need faster internet and larger hard drives).

My money is on a block size increase in the next 1-2 years.
> $12,000 per block

If that's true, then why the hell is anyone mining? Bitcoin is currently trading at $240 or so which is half of break-even if the block reward is 25BTC.

e: Nevermind, I see fryguy's comment now:

> It's 25 BTC + miner fees per block. According to the website linked, it's about 20-30 BTC per block, so at $250 USD/BTC, that's ~$12,000 USD per block of electricity.

I wasn't aware miner fees made up such a large portion of the reward these days.
I didn't. Neither did I give any to Verizon when I signed up (they said they can't, but after insisting they "graciously" agreed to get a $400 deposit instead).
Did your insurance company also not cover it?

I'd always, perhaps naively, assumed an "act of god" was simply covered.

> It's because sometimes people can be vindictive, petty assholes, and it's a small world.

Yes, and posting anonymous untrue grievances in a public forum is exactly the kind of thing that a vindictive person might do. Which is why I don't support that when there is no way for anyone to evaluate the truth of what is being said. I agree with you that the original complaints seems likely to be truthful given Jared's response, but the fact that Jared validated one also opens up the possibility that other people would pile on untruthfully. I don't like it personally.

Anonymous feedback within an organization is a very different thing than posting something like this publicly. I don't even care specifically whether it has a name attached; if it was an anonymous account that had some other posting history, a person could at least look at the other comments posted by this person and decide for themselves whether this person comes off as someone with an axe to grind or not.
I think this happens pretty much everywhere a mobile carrier can profit from selling data about who's doing what. For example, Norwegian company Mobiletech.no has API access to the largest, Nordic mobile carriers' billing gateways and can turn an IP address:port pair from an HTTP/HTTPS connection into a MSISDN, sometimes with additional subscriber details. They're working with advertisers and analytics companies to help them count mobile subscribers instead of unreliable, cookie-based visitors. Similarly, mobile carriers in Denmark have been caught injecting HTTP request headers which leaked the subscriber's phone number, phone model, etc to arbitrary web sites. In Sweden, someone used a similar service to blackmail visitors who watched porn.
