Thanks, HN!
While Pipes was a really cool product, I doubt it would have changed anything. Reminds me google wave, great appeal to engineers but hard to sell to the masses :/
Yahoo has indeed had a product problem for a while, but I think it's more of a consequence of its internal culture of technical mediocrity and IBM-like middle management.
Why So Few Find the Narrow Way
To relax is an act of letting be, just as you say.

But to get at the subtler levels of stress, you need a plan.

The strategies that work on the everyday forms of stress become a disturbance when trying to eliminate the subtler levels of stress.

We agree I think, we are just talking about different levels of stress.

Theorizing isn't the goal. There are a lot of "theory buddhists" who get really into the esoteric philosophy in the scriptures.

I think they are wasting their time.

Stress reduction is something you practice, the theory is only there for when you encounter unfamiliar situations and aren't sure how to proceed.

Of course this whole thread shows how I don't always remember to follow my own advice.
I think you are missing my point. So I'll restate it. sync.Pool does not help with GC issues compared to the JVM because the JVM also has object pools, further those object pools are actually better for the low latency case because the language does not force them to make a choice between dynamic type checks and specific use abstractions.

[edit] As pcwalton points out. My whole argument is actually null and void due to type erasure...doh.
> What if email isn't broken.

I tend to agree. The problem is that we choose to spend our time in a suboptimal manner. The email inbox is just a tool that makes it easier to waste our time. It's not like getting rid of the email inbox will keep others from sending us stuff we don't want or keep our bosses from asking us to do crazy things. If you want to fix email, recognize that you can't respond to everything, and hit the delete button more often.
That's not entirely true either. They can attack your licensure if you aren't current on your student loans. And for certain high-scholastic-debt careers, also makes you lose your job, and therefore further ability to pay said loans.

The scary part is the revocation doesn't have to be for the degree the loan was for. For example, if you tried being a lawyer, and couldn't find a job, you look elsewhere. You decide to join the pipefitters and steamfitters union for plumbing, which requires a license. Later on, the state can remove your license to practice plumbing.

... But you still owe the loans, because even the private educational loans were also federally backed.

Let's take that a step further, though.

The scaremongering over Snowden somehow giving Russia/China these documents is absurd for precisely the reason you cite - their intelligence agencies operate all over the world.

Does anyone genuinely believe that with security so lax at NSA etc. to allow a Snowden-style leak that Russia/China haven't had spies with similar access levels in place for years now?
Student loans are not a problem if you're a surgeon/engineer, because you'll make millions of $ during your career, but they are a problem for dummies studying sociology, gender studies etc.

There are few reasons cost of going to college is so high:

(1) More people wanna go - not just from the US, but people all over the world apply to go to US schools.

(2) Government standing behind the loans. This means that universities/banks don't have to screen applicants based on potential future earnings, but loans are given to everyone, which makes going to college much easier and fuels (1)

(3) Brainwashing since early childhood. "People with college degrees make more money" they say. That might be true, but that doesn't mean it's because they went to college and have a piece of paper. They are accepted to good schools because they are ambitious, hard-working, have wealthy parents with connections, talented, lucky etc. - those things are what makes a person financially successful later on in life. But, propaganda makes students willing to put up with high debt and go to college in the first place. It's a voluntary slavery.
Not sure about everything you say but it looks like Tumblr didn't reach the $100 million revenue goal for 2015. They even marked it down $230 million.

> Precisely - but for some very odd reason, some people seem compelled to defend Venezuela, because it's part of "team lefty" or something

What people? I've occasionally seem Americans on the left praise particular acts of the Venezuelan government, often while at the same time criticizing others -- and I've seen Americans on the left criticize US acts against the Venezuelan government, like overtly backing a coup.

But I haven't seen any substantial defense by notable American leftists of the Venezuelan government on a general level (and certainly nothing to compare with the closeness between, say, the Saudi royal family and notable figures on the right.)
Well, Bank of North Dakota is actually pretty good at what they do, so maybe it was just them.
I'm not sure how you can look at the insanity rife among the student bodies at college campuses today and say that colleges are creating informed, thinking citizens.
Heh, downmods for a question. Classic HN.

Anyway, I checked out the first country (South Korea) in your source. 2014-12-31 estimate of outstanding debt is $424.5 Billion with a credit stock of ~$2.4 trillion.

If you want to only analyze receipts over a short period of time, then I'd guess you can find a positive period for most countries.
They had a new buzzword for new strategic products during the earnings call: "Mavens".
Why? It's a luxury purchase like any other. There's nothing wrong with that. As long as people know what theyre signing up for let them do their thing!

If I get a loan to buy a Ferrari I've made a very bad decision from a purely financial perspective. But if that car brings me enjoyment and makes my life more fulfilling then I'm perfectly happy.

Of course, if the Ferrari dealer lied to me and said that the car's value would go up by 40% as soon as I drove it off the lot then thats a different story.

It is probably true that ple ty of college students don't really know what they're really signing up for. And incredibly misleading statistics about the income of people who went to college vs those who didnt certainly don't help. Pretty much every art history and anthropology major that I've known has been acutely aware that their degree isn't really increasing their earning potential much and are perfectly okay with that.
It wasn't any particularly leftist policies that killed them, it was just trying to artificially boost the value of their currency.

That policy has been tried across he political spectrum and it's pretty much always ended in tears.

>Look at Norway for instance

Norway wasn't suffering from a massive level of poverty. When Chavez took over, Venezuela was and he cut it significantly. That's what he "pissed" the money away on.
Renting out property is a lot more than a large initial financial investment.

Most people I know who do well in that space do so after several years. Once they learn how to be a landlord, learn the quirks of the market they invest in, etc, it can be pretty low stress, although not necessarily hands off.

But if you're just starting out, you should expect to make some mistakes and run into some headaches as you figure things out.
higher risk how?

COmpany A borrow 80k and goes bankrupt - that money goes to collections and comes out of the assets of the company, very unlikely the full amount will be paid back

Alternatively, Person A borrows 80k in student loans and goes bankrupt. 100% of the 80k will still be collected from the student, as student loans are not dischargeable debt. Person A's wages will be garnished, debt resold to collection agencies, credit adversely affected, and yet still the entire amount will be paid back.

If you think the scenario where its possible you never get your money back is less risky, i have a bridge I'd like to sell you.

> in ~2 hours, you can get the open source Parse clone they released going and be back to new

I keep hearing this, and I have a hard time believing it. Are there any examples of a significant app/developer doing this? Sure a working Parse Server is easy to get up and running, but the reason someone wouold choose Parse was to avoid operations, and that's not a service you build in your company in 2 hrs. (as an aside, it looks to me like the Parse Server is a very limited subset of the real Parse)
Exactly this. I want to clarify- I'm not a sharepoint hater. It just has some uglies that prevent people from easily posting stupid things.

If you are going to post something stupid, you have to be MOTIVATED to do so on sharepoint.
I hope it will help too :)

We have the downing of President Evo Morales' plane as evidence in support of that. You can read a more full explanation of that here:

One thing of note is that OpenRC is done via shell script, so going in and adding a ro option should be straight forward.

With systemd it is done in the C code of their init binary, thus you have to work around it by a remount on fstab.

So, let's start with the basics: the profit margin. Basically, if it costs you $1 to make a good, and you sell it for $2, then you have a $1 margin.

The current data shows that margins are quite wide. This means that companies are selling products, services, etc, at a cost that's a lot higher than it's taking to produce them.

This is normally explained through things like labour arbitrage (move production to cheaper places), efficiency gains through technology, and demand growth that allows one to command higher prices for the same goods.

Basically anything that allows you to either cut production costs or increase prices.

But, a large profit margin means a competitor should be able to step into the market, by accepting a lower margin in order to reduce prices. This is the "pricing cycle" they refer to in the article. If that doesn't happen, that indicates something fundamentally odd is going on in the system.
Yes also, the TLV nature of ION means that you have to buffer the ION data while writing it, in case you don't know the full size of the embedded ahead of time. However, this is really only a problem for very big messages. HTTP has worked like that for a long time already, and HTTP servers have proven capable of scaling pretty well, won't you agree?

Additionally, if a message does not include its length up front, you are just trading faster write time for slower read time. A node receiving dynamically sized data then has the problem of knowing how much data to allocate for the full message, plus the receiver has to inspect the data as it comes in to see where it ends. With an ION message the receiver knows within the first 4-5 bytes (typically) how big that message will be, and can thus copy the following bytes directly into the perfectly allocated memory area, without having to examine them any further. Since data is most often read more times than written (e.g. data written to a file), we felt that making a tradeoff that favors read speed over write speed made sense.

Pipes was really cool. Their email still sought after (at least in latin america) for corporate customers. Perhaps a SaaS spin off with email, pipes, ecommerce search/recommendation and other cool tools they release all these years ?
Ask HN: How about a jquery interface to any website through scraping and caching?
What do you think of a jquery interface to any website through scraping and caching?
Parse made a lot of sense to me. Building a simple backend isn't much work, but operating it sucks. You get to deal with script kiddies, hackers, hard drives dying, services crapping themselves at inconvenient times of day, backups, testing backups, security updates (and what is probably more work, monitoring security updates) for the OS and web server and proxy and db and on and on. Maybe there isn't a pricing model that makes this work, but I think there's a real desire.
They are, because their state funding is increasing at a lower rate than inflation, and because they have to pay for new buildings and equipment to support growing student populations.

And contrary to right-wing pundits, growing student populations are not a problem, they are the stated goal of public universities. You can't just raise tuition to discourage people from applying because the entire point is to get as many applicants as possible.
You didn't seem to grasp my point.

Management is a resource a company can throw at a problem. Leadership is not. Positing solutions that can't be implemented is the very definition of wishful thinking. Calling it a lack of leadership isn't helpful. You need to break the problem down further and try to find a way to solve it that doesn't involve supermen.
That's because Venezuela is a de-facto narco state at this point. The politicians are denying reality because they make a lot of money by facilitating the global drug trade.

Venezuela is the key link in the global narcotics supply chain: heroin comes in from central Asia and is then smuggled by Mexican cartels into the US, and cocaine comes in from Colombia and Peru to be shipped overseas and ultimately land in Europe.

The Chavist politicians have an active interest in unseeing reality. Reality is that they are screwing over the population in order to stay in power at any cost so they can continue to line their pockets with drug money. That's not the narrative they want to tell, so they change it.
You can give up your right to bring a civil suit, it doesn't impact your right to a jury in a criminal trial. That's a very important difference.
>we're potentially only a few years away

The press loves to hype this sort of thing but I think if you talk to most scientists in the field they'll be much more circumspect about getting to commercial fusion. Personally I think it's at least twenty years out, and that's if everything goes well, which it will not.
Dave Ramsey has a dim opinion of college loans that should be broadcast further than it currently reaches.

Many, if not most, college students and parents therof seem ignorant of Ramsey's sensible recommendations. As "Lie #4 about college loans" Ramsey declares: "I can’t afford to go to college without a student loan."

from "9 Biggest Lies About College and Student Loans":

I thought the lesson of Venezuela was that seizing control of the entire economy is a good way to wreck it. Venezuela had serious problems long before oil prices crashed, and "running out of other people's money" is just exposing the problems of their disastrous policies, it's not the cause of those problems.

That's one of those really basic things that I'd bet well over half the adult population of the US couldn't explain, if asked. Like how marginal tax rates work.
> https://en.wikipedia.org/wiki/Great_Recession

I really wish to hear from people who support rightist causes what they think of this and if there's anything, any hypothetical event, that they would accept, if happened, as a proof that rightist policies are bad.

If you actually read the article they are quite reticent to blame socialism as the root cause but rather economic mismanagement and cronyism. This is a feature of many Latin American states regardless of left or right politics. In contrast socialism seems to be working just fine in Canada and Northern Europe.

In any case the current surge of left-leaning politics in the US is a symptom of massive economic inequality. If rightist politics had an answer for that, anything other than "just work harder," then people wouldn't be so quick to look to the left.
To be fair, though, aren't generics on the JVM type-erased? So you're going to have a type assertion at the JIT level either way.
I work with a lot of young guys who are stressing about their loans. You make a good point.

What are they supposed to do? These days you absolutely need a college degree to have a chance in the workplace so you have to take the loans if you like it or not. No options besides having a rich dad.
The artist's works from her website: http://placesiveneverbeen.com/index.php/body/
The bankruptcy prohibition is why you even see loans in the single digits.

You have a typical 18 year old with zero credit history and zero real income. You have a loan that may take many years to repay, but unlike a mortgage there is no house to repossess if the loan goes bad. You can't repo a degree.

A good exercise is to imagine that you're a lender writing checks with your own money. Would you even make loans to somebody majoring outside of STEM? What interest would you charge especially given other options for investing your capital? How would you have to adjust your interest rates if students were allowed to declare bankruptcy to discharge their debt to you?

People that have loans they need to pay back and no rich parents to pay them for you don't go out and start companies.

Comments like this may be well-intended but do not provide advice which is useful for people without certain forms of economic privilege and may be perceived as insulting to people without certain forms of economic privilege who did, indeed, go out and start companies.
He was the one who discovered the oil deposits (due to his extensive expertise from British Petroleum). I don't think he managed Norway's finances.
Though I can't recommend it, there would actually be better outcomes if we banned loans for college. Flooding the higher education market with cash has made it less affordable not more. Having people be responsible for the cost up front would make them better shoppers and the colleges more lean. Prices would come back down to reasonable levels.
