First:

A future is a contract to buy or sell something at a set price.

So for example a Crude Oil Jan 1st buy future requires that you buy Crude Oil at a set price on January 1st.

Now, if you want to own crude oil on January 1st, you buy a future locking in a price.

This means the cost of your crude oil is predictable ahead of time.

It also means if crude oil is more expensive then you save money. But if it's cheaper you've lost out.

Businesses benefit a lot from predictable pricing - for example if you're a farmer you can sell grain futures at a set price. Then you know that your grain will get you an amount of money - guaranteeing incoming.

This is the mainstay of what CBOE and CME does.

Bitcoin is a cash-settled future. So instead of actually owning a bitcoin, the way it's settled is based on the market price of bitcoin at the time.

So I put a bid in for a 1 week Bitcoin future at $20,000. I'm matched with a seller for a 1 week Bitcoin future asking for $20,000.

After a week the price for Bitcoin is checked. It's actually $21,000. The seller has to pay me $1,000.

In reality no-one is going to be doing 1 week BTC initially - BTC is just too volatile.

The exchange rules on CME are apparently if BTC rises/falls more than 7% trading stops. (So on the volatile days last week it would have stopped multiple times in the same day!). 7% is really high for a normal financial instrument - but BTC is very very volatile.
Probably not. Currency isn't a search engine. It's a fundamental piece of an efficient economy. There's a reason we went to fiat currencies. I like a lot of things about bitcoin actually. I want to see an energy based currency evolve (without the actual expenditure of energy). That currency can basically be a formula that calculates value based on energy consumption and output. I think something like that would allow for a more sustainable economy.

This setup makes for an interesting blog post, but it goes too far toward being an IDE for my taste. Part of what I like about Vim is that you can customize it to be anything from just text editing—albeit fast and productive text editing—to a full-blown (if hacked-together) IDE.

I think what I would like is a way to embed Vim or Neovim into Rstudio. Rstudio's Vim mode is nice, but I'm too used to my own customizations. It looks like people have experimented with doing this: https://github.com/jalvesaq/Nvim-R/issues/142.
Have you thought about adding some kind of reputation system? To give incentive for contribution by users.

A voting system could also be useful in verifying that the content is accurate/relevant to users.
Shouldn't something like this be deliverable with a set of Fabric or similar scripts?
Headline is slightly misleading:

>A United Nations official investigating poverty in the United States was shocked at the level of environmental degradation in some areas of rural Alabama, saying he had never seen anything like it in the developed world.

i.e., the worst poverty the official had ever seen in the developed world, not the worst according to some comprehensive study.
The line that has always stuck with me:

μνάσασθαί τινά φαιμι †καὶ ἕτερον† ἀμμέων

"I think men will remember us even hereafter."

There are other translations, but the core idea, that this woman writing ~2600 years ago grokked that she and her words we be known to humans across so many years, really seems powerful to me.
HN moderation is notoriously fickle and is a core weakness of this site. I wouldn't let the downvotes get you down.

I'm using Dokku to serve a bunch of sites and love it, it has made deployments a breeze. I did run into some Docker problems (used too much CPU and couldn't connect to its socket, etc), but I don't think it was Dokku's fault, but Docker's.

I want to see if I can use Kubernetes as a Dokku replacement (hopefully a more stable one), but I don't think Kubernetes has all the niceties Dokku has (automatic reverse proxying, Let's Encrypt support, etc).
In all curves in the image, the shaded area is either centered on the "crown" of the wave or occupies the descending portion of the wave.

What is the visual effect if the ascending portion of each wave is the shaded portion?
Took me a while to work out this was upside down compared to what twitter does. Once I figured that out it made a little more sense.

Well I'm sure the fine folks of Alabama will sleep better at night knowing this.
"Use contractors, they said. It's so much easier and cheaper, they said..."

I don't have any evidence as to the accuracy of this anecdote, but when I see those news stories about delivery drivers shitting on someone's lawn, this is right where my mind goes.

'That person probably had an insane deadline to meet and no protections ensuring that they get time for basic and universal human functions.'
I would have thought Mississippi but it doesn’t surprise me that it’s in the South. Huntsville has some defense work and I know there’s a Mercedes plant (in Vance, I had to look that up). But I can’t think of anything else in the state.

My favorite part of Project Euler is the solutions forum that you can access after entering the correct answer to a problem. Having different solutions to the same problem to browse though is fantastic for learning new idioms and tricks.

Sadly, only a small portion of the solutions posted are retained, so if you're not looking for Python or C you'll probably only see a couple of different variations in your language of interest. It would be a huge deal for learning new languages if we could retain all solutions and then sort or filter by language.
Ugh, yeah, what would those United Nations officials whose job it is to investigate poverty know about poverty.
You might already know about this, but if you're looking to learn Coq, I would recommend the Software Foundations series (https://softwarefoundations.cis.upenn.edu/).
I was refuting his claim that no one expects that quotes imply an assertion of verbatim quote.

I don't understand how you've refuted that while also saying they sometimes don't. Are we arguing about contexts here? My claim is almost trivial - nobody reasonably familiar with English thinks quotes imply a verbatim quote. That's just not what quotes are for.

This would be interesting (and useful) if any of the assertions came with explanations.
Well this was really disappointing. I imagine the number of the things in here or really useful but without more details on WHY you should or shouldn’t do some of these things… I’m not sure why I should follow.

This is essentially a simple bulleted list.
Oh, suck it up.

From a business perspective, the most important thing -- indeed, the only thing that truly matters -- isn't the software itself. It's support. When it comes to open source, you either use a supported configuration or you assume ALL the responsibility for supporting your systems yourself. Who would you rather handle the support on the off chance your machine goes tits up? You? Or Red Hat?

No wait, scratch that. Who would YOUR BOSS rather handle the support?

The supported init system for most flavors of Linux (that aren't in LTS) is systemd. Systemd makes the most sense from a business perspective, and "but muh Unix philosophy" doesn't hold when there's money on the line. May as well get used to it.
Japan and Korea have very strong social drinking cultures, so I don’t think it’s really a question of East vs West.
The slums in the Paris suburbs are pretty well known.
The bank would have no capital to lend at fractional reserve. It could not lend out 90% deposit value without getting run on, because there is no deposit insurance. There is no M1 money supply growth coming from the central bank. You would be buying a bond but also necessarily acknowledging the possibility of default, unlike today in the funny money world of perpetual debt money.
Same here. But different people value different things out of relationships. I prefer to have a handful of people close to me and don't seek out daily updates on everyone else.

In fact, I enjoy running into those people or meeting up with them periodically even more because then they can tell me everything they've been going through in person. To me that's more fun than getting a stream of micro updates on everyone.
A sampling of people who will benefit or lose from the new US tax plan
I remember seeing somewhere that they mostly rely on Mountain Dew for hydration and even feed it to the baby, so bad that they have early tooth decay issues. Apparently the amount of people living in trailer parks is huge and constantly growing.

Troubling when you think that this is happening in the US. I saw that kind of situation in central america.
Write your shit in assembly then. Everything else is bound to be slower than assembly.

This is indeed true, and IIUC using Shadow DOM would be a workable mitigation.

Btw, ignore caniuse etc - Firefox _technically_ does support Shadow DOM, just version 0, which it has apparently supported for a little while now. It's better than nothing in a pinch.

Chrome et al are at Shadow DOM v1, which is what caniuse tests its support/no-support metrics against.
You don't need to fall back to a "default expectation" when usage is adequately indicated by context and by good faith efforts to interpret a statement in it's most reasonable form. Nobody confused it for a literal quote, nor did anybody feel it caused any misunderstanding, and those realities preempt any need to appeal to a default expectation.
Hong Kong's Coffin Cubicles
Its not unreasonable, given that some companies demand passionate rockstar unicorn engineers, yet most companies will not grant that request - they will instead exploit that passion into workaholism and leave you holding the bag when you burnout. So as engineers, we must demand equally that "passion" not be a requirement.
>> Facebook makes fantastic communications tool and gives them away for a whopping $0.

Mostly-off-topic:

The `bisect-binary` project listed in the introduction is almost the _exact_ program I made while I was a devious high school student trying to circumvent weak (i.e. most widely-used-) antivirus software by locating a few "key" bytes in the binary that the AV used to fingerprint a virus.

I would zero out half the file, scan the file with AV, then recursively repeat the same for any zero'd regions of files that AV didn't consider a virus. Essentially a search of the file for the smallest set of bytes that needed to be changed for AV to fail detection.

Usually this would result in only a small number of bytes that needed to be slightly tweaked.

Pretty unproductive "hobby", but I must admit it was really fun. :)
There is a difference between coding in your off time and reading Hacker News. What you're describing is someone who is relaxing not working. Aka great don't work long days mastering an instrument, just put in their 9-5 and casually have fun. So sure, if someone does not keep abreast of computing in their free time that's not a great sign, but deliberate practice works best a few hours a day not 10+.

PS: What side projects do provide is a way to have more experience than your number of years in the field would suggest. But, that has heavy diminishing returns.
Seems so, but if the lemons are getting crushed through small fault of your own, does it hurt to make lemonade? It's an interesting discussion regardless.

I don't know if we'll see an entire global collapse, but I think we'll see a lot of displacement that stresses communities already overly sensitive to migration. Not to mention the likely deadly impact on many people.

That, to me, should be reason enough to act rather than ignore as impacting only "those people over there".

Unfortunate headline. Would expect to see it changed.

Growing up I spent a few years in Alabama. Not at all surprised by any of this, but it's not "the worst in the United States", or the developed world, by any stretch.

Not that it's a competition, but census data would put a couple of states (I believe consistently Louisiana, West Virginia, & Arkansas) below Alabama in median household income.
As another user mentioned, many git actions scale linearly in the number of changes, not in the size of the repository. Try recreating the scaled repo, but say, in commits of 1000 lines each (ie. 200K commits), and see how long things take.
> he environmental impacts of the US beef industry are in the same ballpark as the Chinese pork industry.

The very article you linked put the entire amount of US farm waste at 335 million tons. This is much less than China's 1.3 billion tonnes (AKA "metric tons") for pork alone.

https://s3.amazonaws.com/cd.live/uploads/content_image/conte...

> America's CO2 emissions per capita are still more than twice that of China.

Again, from the standpoint of the environment, there is no extra credit for being absurdly overpopulated.

China emits more CO2 than the US, the EU and Russia combined.

I find myself thinking about the effects of social media on humans.

I feel we entered The Button Age. Want a pizza? Hit this button. Want to get groceries delivered? Want to watch a movie? Hit a button. Want to show you care about some cause or event? Hit a button. Want to reward your brain with dopamine and feed your narcissistic behaviors by pretending that viewing a curated timeline of people's "lives" is friendship? Happy Birthday, press the button.

We are perpetuating a simulacron of human relationship.
What a fun little game! Well done

True, I just meant that he doesn't really acknowledge the harm that it does. Oh well, at least people are becoming more aware of it.
Contentious public debates with people I barely know is exactly why I use Facebook less than I used to.
I had an entertaining few days working with Confluent's Kafka Connect stuff. I was trying to connect a MySQL table to Kafka and then on out to Hadoop. Amusingly, Kafka Connect wanted to use a queue with the same name as my table (MySQL or Hive / Hadoop, I don't recall which end); but of course since Kafka doesn't have namespaces, I had better hope that my table name is unique across the whole cluster!

It was around about then that I figured out that Confluent was a bunch of kids playing at building stuff. I have zero doubt that it's a good base if you have an enormous firehose of data, but look for features beyond raw performance and basic correctness, and it's underdeveloped. Basic stuff like back-pressure - don't expect it, either overallocate your storage or make sure you always have faster consumers than producers.
It appears OP is looking for some solid foundational skills to help them make decisions. I don't see any issues with that.

You could do that, as you suggest, on someone else's dime/risk profile, but they want to bear it themselves. Why not?

Hmmmmm. This really doesn't seem much of a sexist problem to me. In my opinion, whether wanting to publish female pictures is sexist or not is very controversial. Sex sells, and attractive females gain more attention than attractive males.

The issue was the intimidation, which is arguably not related to sexism. A man with an unpopular opinion could have gotten similar intimidation.
How about "reveal"?
Yeah, not bothered at all, just wondering if I missed something.
From what I remember and what I can find, that was something that was particularly found in Appalachia, not Alabama (see this article[0]). A quick check on Google maps shows that Alabama is about as far from Appalachia (in West Virginia) as London, UK, is from Hamburg, Germany. So I think it's a stretch to say they're in the same geographic area.

Incidentally, I've been using the 5-minute USCRN dataset provided online [1] for load testing, and one of the stations is Barrow (lat/lon: 71.32,-156.61). Data starts in 2006.

Out of curiosity I just did some basic SQL queries on the dataset (min, max, average) and the graphs look slightly different from those in the article. The annual average temperature 2006 vs 2016 shows no difference for example. [2]

And if it is a "3rd world" state, why aren't people jumping to donate and help and aid them?

"Cuz 'rednecks." The only group you're allowed to prosecute on TV, media, and public discourse.

But if liberals were running in and giving free aid, and helping lives, those people would start to like liberals.

I mean, when we help people in Ghana, do we check to make sure they don't have any conflicting political values? When we aid Syria, have we checked to make sure they're there aren't any nationalists and racists?

I'd love to hear an actual rebuttal, but I guess I'll have to settle for downvotes from people who can't. I guess bigotry is okay when it's people you hate.
Does Life End at 35? (2013)
Not sure what world you live in, but the vast majority of new people interested in Bitcoin are interested because they want to make money, not because they believe in the technology. They want to buy in, see it go up 500%, and cash out.

They're not motivated by the actions of the central banks, they likely have no idea what the central banks do. They see "Bitcoin increases 100% in a day!" on the news or on a website and want in on that sweet money making. Coinbase makes it so easy, they have to do absolutely minimal research, don't even have to wait for transactions to be confirmed.

You think its lack of faith in the current banking system and belief in the new tech that's driving the price up as high as it is now, when it's mostly greed and ease of access. Taking that into account it's naive to not believe there is a Bitcoin bubble.
To me it seems like Goliath becomes way stronger than any other ship once you have a lot of upgrades. Basically impossible to kill someone playing it safe with a max upgraded Goliath
I'm far more uncomfortable assuming everyone has the interest to follow up on every comment.

Alternatively I prefer to assume that it'll give our commentary more value if we provide some helpful context.

I suppose your full node client software must have pop-up windows when forks happen and you are prompted to click "accept" or "reject"; and when invalid blocks are detected, it prompts you if you would like to "accept", "re-try", or "delete".
> ... they catched those slik road guys because they were using bitcoin ...

No, that caught them because they were careless. Ross linked Silk Road to his meatspace email address in posts to Bitcoin Forum. And misconfigured Apache to leak Silk Road error messages via clearnet. And kept personal information about his staff on a laptop (albeit LUKS-encrypted) that he used in a coffee shop, and at at public library. Also chat logs, and a comprehensive diary.

Not Bitcoin!
Article has a picture of a falling down house. But guess what, it's a house!

Go look under an overpass in San Francisco to see even more dire poverty and even less chance of self obtaining minimum standards of living (i.e food and basic shelter) as cost of shelter is so far removed from potential income.

But probably stating California has worst poverty in developed world doesn't support the underlying motive of the article.

Incidentally, Alabama does have a lot of poverty and isn't a place most of would be comfortable living due to social climate. Which is a real shame because I find it to be quite a beautiful state, at least the areas I've seen.
> I mean, when we help people in Ghana, do we check to make sure they don't have any conflicting political values?

I think there is a critical difference between Ghana and Alabama, and that is that Ghana does not have representatives in Congress making policy decisions affecting all of America.

In all honesty it's more a comfort thing: I'm so used to vanilla Python that the extra stuff in Pandas messes with my head. It's just easier for me to work in a completely different language.

Also J is more fun as a puzzle language, so I use it for personal projects. If I was writing stuff for production I'd probably (if begrudgingly) use Pandas instead.

Why has this disappeared from the front page?
It's such a complex situation. Amazon has contracts with small companies who provide trucks and humans. Amazon provides the work, the groups of packages, the routes, the app the drivers need to use to deliver.

The companies compete with each other for more 'routes' each day. They offer to take on more work, to do more. And then they hire anyone they can to fulfill those routes. The drivers themselves are on contracts with the small companies that can end at any time. Not making your rate? Up to the small company to decide if you have a contract tomorrow.

The contracts themselves presume the drivers will deliver a route in a specific number of hours for a fixed rate of pay. But newbies work at a much slower rate. And during the holiday season, they need a lot of extra labor- a lot of newbies.

Who is to blame? Amazon? The companies? The drivers? Capitalism gone mad? Take your pick.
Yup, agreed - that was what I was trying to convey.
They also deliver very late at night, past 11pm kind of late.
