It's more of a 'The concept is 30 years old' thing. Some of the reasons driving the commercial development only became factors in the market more recently; things like fuel efficiency and airport noise restrictions. Also, one of the less discussed advantages (as a customer) for the geared turbo fan is the decrease in expected maintenance/repair costs on the life of the engine. That's big business for engine manufacturers and there will be less of it with this design.
Out of curiosity...why run this as a service?

EDIT: I misread this and though it was only a client. Geez. If it's a server, then of course it should be a service.
It's a little odd, given that Kernighan and Pike have written a couple of excellent programming books together, and with Rob Pike's leadership in the Go project, that this one isn't K&P.

I learned erlang first, years ago. I absolutely fell in love with it. Somewhere when I wasn't writing a lot of erlang code, it crusted over and now the erlang syntax bothers me. While elixir is more than a syntax, yes, that is part of its value for me.

To me, in my head, symbolically Elixir and Erlang are the same language, the concepts I'm using most of the time are representable in both. I just find Elixir more fun and easier to write quickly.

No, we settled on temperature through years of careful, tedious experimentation involving the expansion of gases.

Much later, we figured out what it actually meant in terms of atoms.
This idea would unfortunately negate one of the top benefits of a high-bypass turbofan. Noise reduction.
Of course. I don't think anyone is pretending like Elixir isn't built on top of erlang.
> Then there are are the fair, neutral, unbiased economists who disagree with Piketty, who are only motivated by the search for the truth.

There is no such thing as truth in Economics. There's not even a defined goal. Creating a mathematical model of how 7 billion people behave in a global economy is impossible.

You're always going to have to simplify your model enough for it to be useful, as the expense of something. That compromise is your bias. Economists always make assumptions about something, and those assumptions are always driven by some sort of world view.

Not to mention, the other part of economics is deciding what policies or actions should be taken. Do you optimize for economic growth? For happiness? To reduce inequality? To eliminate poverty? Maximum employment?

Other sciences describe things which can be replicated, or things which are (more or less) concrete. Economics can't be a concrete, truthful science because people are react to their environment, which is ever changing and will never be the same at 2 points in history. And everything affects human behaviour, from the weather to things like religion which aren't exactly concrete...
There's a long negative history of high-speed gearing. Jet engines have one big rotating unit, and that basic simplicity is good for reliability. Turboprops have a gearbox, and fragile, high-maintenance gearboxes are a long-standing problem with turboprops. Adding a gearbox without reducing reliability is a major achievement.

I want to add my own experience here: I moved to Seattle from NYC, and to NYC from Savannah, GA.

In Savannah, finding an apartment was as easy as driving by a house and checking it out. Craigslist was the de facto method, though. Never any misrepresentation, or other real estate trickery going on. As a student of the local private art & design school, my enrollment there was as good of credit as I ever needed. Often a jobless student could walk into an apartment with the landlord and sign the paper right there, without any background checks or financial statements. I thought this was reality.

In NYC the fact that brokers required bank statements, tax returns, credit check, background check, pay stubs, plus all of that and more from a co-signer (if needed) was downright disrespectful and degrading. Not to mention paying a broker 2 months worth of rent meant they never tried to get you a deal. Don't even think of using Craigslist in NYC.

Now I live in an apartment in Seattle. It's on the west side of Queen Anne hill, with a view of Elliot Bay. We found it on Craigslist. The price was so good we knew it was a scam and almost wrote it off entirely, based on our experience in NYC. Turned out it was exactly as pictured, and even better. We've lived in it for just over 3 years now and have no desire to move.

If brokers are the standard way of purchasing in major cities, then that is a real shame. I find them to be pure slime, absolutely the worst people to be dealing with. Anything that disrupts their industry is a good thing.

Why not just have it reply with a "verified" signal when you enter a predefined PIN? That way you're mimicking the card's original behavior with a different PIN code.
The author writes about spinning virtual machine from Linode.

There's one cool alternative I found: Hetzner Online[1] leases dedicated hardware that their other customers stopped using or ordered but didn't use, etc. It is in form of reverse auction - unused hardware gets cheaper until someone rents it.

You can get i7-3770 server with 2x3 TB disks and 16 GB RAM for 32 EUR per month. That's not much more money than linode, but it is much beefier and just your (but no SSD). If you pay more you can get something like i7-3770 with 32 GB RAM, 2x3 TB disks and 2x240 GB SSD for 65 EUR a month.

The servers are in Germany, which might be interesting for Europeans who are wary of US cloud companies.

I'm not affiliated with them in any way, I just find their offer cool.

Ask HN: Bad tests better than no tests?
I can see this going both ways. But I think a project without tests would be less toxic than a project with bad tests. I'm curious what your thoughts are on this.
...or, making sure that the customer was aware of IBM's own published documentation, linked to in the paper, which explains the difference in how CPU utilization may be calculated by AIX vs. Linux on the same hardware.

You might wish to look at the paper describing how the PURR and SPURR components of recent POWER cpus assist with process accounting.

I understand that there's going to be some inevitable Lintel chauvinism on HN, insofar as it's the most popular platform...but there may truly be other legitimate ways of doing things.
Fun fact: the S3 API actually makes no such claim.

http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT...

Nope. Let's try the developer guide.

http://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class...

Nope again. Let's try the FAQ.

https://aws.amazon.com/s3/faqs/

They claim S3 is "designed for" 99.999999999% durability, but there's neither a guarantee nor a clear definition of when an object starts to be covered by one. While it's both intuitively obvious and conventional wisdom that an object is durable at the end of a PUT, as far as I've ever been able to tell Amazon doesn't come out and say so.

That's one of the problems with company-defined "standards" BTW. This kind of issue would surely have been noticed and discussed in any kind of open standards process. It's what makes those processes so tedious. De facto standards can be turned around a lot faster, but there's a necessary sacrifice in precision to go with that.

this will ultimately depend if the new company came to you or if you went to the new company.

If they want you they probably have an acquisition price in mind i.e salary + benefits but you are in a decent bargaining position for any potential losses.

If you have gone to them then I am not sure they would really entertain the idea.

If they did agree to discuss it you may want to consider asking for a like for like compensation in the event you do lose your options/bonus etc, as you dont know what exactly you would lose until you tell your current firm you are leaving.
just remove the fan from the turbine altogether

I don't think you can. The large volume of airflow surrounding the turbine is what makes it a turbofan[1]. Without, it is a turbojet[2]. The airflow from the turbofan surrounds the hot exhaust gas and it is much quieter than the turbojet.

But, other than noise, the rest of your comment makes a lot of sense to me. But I know very little about this stuff.

Not quite as lucky as you think. The female reproductive system runs in cycles and is in many different states at different times. We happened to figure out how to use the switches that nature already has. Men, on the other hand, have one state. On, all the time, from puberty till death.
If you want to bring history into it, recall that Microsoft (and to a lesser extent, Unix vendors themselves like Sun and SCO) did a great job of disrupting the adoption of Linux in the 90s and spreading FUD among normal people and IT types.

I blogged about a very similar topic (in biology) over a year ago: http://federicov.github.io/Blog/deception-by-mathematics.htm...

People give a lot of authority to mathematics, because mathematics is immensely powerful to explain the natural world. This unfortunately leaves the opening for charlatans to do fake math and lend their garbage research a completely unwarranted air of legitimacy.
It really depends on what you're doing, but even in common obvious stuff like networking, there can be functionality in libcurl or OpenSSL that you really need but isn't replicated in Go. Several years ago I remember trying to do SSL certificate verification with Python and finding the standard library lacking.

Also bear in mind that good compatibility with C also means good compatibility with just about every other compiled language, including Rust.

Facebook is simply an evil company that you should loathe just like any other malicious operator on the internet. What the heck is wrong with people that everyone would be so smitten with the psychopaths at Facebook.

I can tell you, you would be pissed off. But instead, you simply feed ever more information into the Facebook global surveillance system. Good job.
Rust has some compiler plugin magic that can help you write code resistant to timing attacks.
Not to be rude, but these complaints, minus the "increase" are standard Heroku practice. I see no changes-- in fact, what has changed there, anything?

They're finally too expensive for you, or you outgrew them? They aren't cheap, and never have been, especially for hobbyists.

If you have a hobby, you most likely have more time than money to complete your hobby, so why, why use something like Heroku? The very nature of your activity is to spend your time, not your money, Heroku is only giving you the feeling of savings until you outgrow their nearly worthless free offering. Now you have to spend your time, moving, configuring, and learning an "entirely new" system. Had you done this the first time, you'd have saved money/time.

Yeah... "git push" to deploy is easy[1]-- and if you're new to application development it can be nice, but! It also means you have no idea how to configure or run your app (i.e. deploy). It means you're more vulnerable to your vendors quarterly earnings needs (price hikes), it means you're more vulnerable to vendor technology changes (lock-in), it also means if it ever hits the fan-- you're gonna have oodles of downtime while you learn how to do it "right" the first (nth) time.

FWIW, it's actually really easy to run a VPS that's stable once you learn how to do it properly. Don't fear it, mate. I've always found it nice since none of my projects ever get substantial traffic, I can usually run some auxiliary service I need (like Gitlab) on it too. A two for one, eh?

... One last thing, if you're running a business Heroku might be the right choice (it's up to you to evaluate the risk/reward).

[1] I personally think deploying with Capistrano is a cinch (cap deploy) but it'll take you a lil' bit of effort to set up the first time.
About TokuDB and PostgreSQL

How does one ,by tunning a vanilla PostgreSQL (on a per instance or per database or per table basis) can get the same kind of advantages (and tradeoff) than in MySQL/MariaDB by switching from InnoDB to TokuDB ?
And noise reduction is actually a really important benefit of this engine as some airports have restrictions on noise.
It should be noted that a "temperature scale" is a pretty non-obvious thing. The idea that the temperature we call "ten degrees" is as much colder than "twenty degrees" as that is colder than "thirty degrees" is something you'd never figure out without getting as far as the 18th century.

Even the concept of "temperature" is not obvious. Give someone a hot piece of bread and a hot piece of metal and the metal seems hotter even if they're at the same temperature.
I don't know anything about PowerShell, but I have a similar question, I think: how is this going to work? Will I be able to do something like this command line (from my *nix machine)?

ssh user@windows.machine.local dir d: | less
I don't think that's the point. For random hookups, people really should be using condoms; STIs are a thing. But for couples in trusting relationships, I don't see why men would be less trustworthy than women. Having an extra layer of protection outside of condoms, and being able to not have the responsibility being all on the woman would be really nice. Some women can't tolerate various other forms of birth control for health reasons.
How else would you expect an SSH server to run? As a desktop application?
I see a couple of things missing in the comments thus far on George Bell's isolation.

First, his age. When he was younger, he was (presumably) in love with, and almost married, a woman whom he stayed in touch with for the rest of his life. He also had close relationships with friends. For some people, the "desaturation" of life that comes with age makes it feel less worthwhile to pursue the things that once made them happy.

Second, some people who do not socialize are not necessarily devoid of the inner need for friendship and companionship - they may have learned that the pain and risk that can come with social connections outweigh the advantages.

When a man becomes old, disabled, and considerably overweight, interacting with others might not be a particularly pleasant experience.

There are no "solutions" to the "problems" George Bell had. They are a part of the human condition, and they were his experience of life.
I would have thought legal cocaine was a more appropriate comparator. Heroin and meth are so different in effect that I seriously doubt your claim that one is just a substitute for the other.
Thanks for the thoughtful response and citations.

When you mention moving "marketing and sales to the US" is that simply so they can better target the US market? I imagine there is simply a larger opportunity in targeting the US, and in this day and age, there's no reason you need to start a locally-targeted business if your economy is in the crapper when there are other nations with much healthier economies.

Also, can you elaborate a bit further on the "not-entrepreneur-friendly mindset" you referenced?
Can't make a coherent response, so you hit the downvote button out of frustration. lol.
> you're looking at a 10% off the top of the transaction

Brokers in NYC routinely try to charge two months' rent, which is a whopping 16% of the rent.

I've had them try to tell me, with a straight face, that it's only 6-10%. They always look surprised when I ask them what two twelfths is. I think that some of them literally don't know what the actual percentage is.
I have a problem of talking over friends [in two-part conversation]; primarily because I've already established what they're saying and so I skip to my turn - mostly I can catch it and slow down the conversation on my end to match their pace of delivery.

It's kinda like when I can't remember a word, or a person, usually my wife - or a close friend - will have established who it is or what I'm talking about, the word doesn't need filling in to convey the meaning to that particular person.

It also turns up with acquaintances who might broach a topic I'm familiar with, they take a slow pace to allow me to follow - but interrupting demonstrates I know what they're on about and allows them to up the density of the conversation. I see this as beneficial; others detest it I'm sure.

>Stopping people talking over others makes life better for everyone //

Why let someone gabble on if the whole group already is at that level of understanding on the subject though; is that really better?

That may happen, but it doesn't answer the question what the cut will be. I don't think there is an answer, since as GP pointed out, in free market, both margins should approach 0, so the ratio can be anything in that limit.

This also raises a question, if no one can make a profit, why should people want free market? Basically, free market promises subsistence wages to workers.

And what about consumers switching to distributors? That's the problem, you (wrongly) see economy as having two parts - one part producers, another part consumers (and so presumably you put distributors together with producers), but it really isn't like that, it's cyclic. You can't always hammer it into some supply-demand model (that's actually what makes the example interesting!).

There seems to be no data supporting the article's assertion that roundabouts are being replaced by traffic lights across the UK as a whole. I'll add my own anecdata: many more roundabouts are being built in my area of the UK. There are also roundabouts with traffic lights.

As a driver, I much prefer roundabouts. When I'm cycling, I just prefer roads with fewer cars and can't wait for self-driving cars, since at least they won't be driven by idiots.

> The lesson of the USSR seems to have been...

...that victors write the history books.

Seriously, the notion that there was a single cause for the decline of the USSR -- and that this cause corresponds exactly to the ideologies at the heart of its antagonistic relationship with its enemies -- is prime facia suspicious. There were a myriad of economic, structural, political, environmental, geopolitical, and military reasons for the collapse of the USSR. Boiling all of that down to "Socialism Bad" is a nice rallying cry, but not exactly a helpful analysis (or at all likely to be very accurate).

>... because the inefficient universities would be out competed by the efficient ones

What does this even mean? What does it mean for a university to be "efficient"?

I think you're confusing what ideology claims should happen with observable reality; namely, that higher education in the US is 1) closer to a free market than peer nations; and 2) horrendously more expensive than peer nations.

>... because universities are not a perfectly free market

It's one thing to say "we don't know what works, so let's try the thing that one particular ideology prescribes."

It's another thing to say "Those people over there don't have our problem. I bet the reason is because we're not doubled down on the exact opposite of what they're doing."

In any case, I think I answered above why a free market won't fix higher education: brand names / flashy stadiums / dorms / academic buildings sell better than good instruction and solid research.
