I would kill to answer questions on the corner cases of modern web languages, such as JS, Ruby, Python or Dart. Pretty cool idea.
My point was that "saving 25 GiB" is way below anything they can possibly care about. How much traffic does 4chan handle in a single hour? I think it's pretty safe to assume that 25 GiB is significantly lower than one standard deviation of their monthly traffic, so cutting costs with it is also not feasible.
Please explain why Node shouldn't be permitted or wouldn't be appropriate for "advanced" scenarios. What advantage does Node acquire by resisting fibers & threads inclusion? You seem to have a set characterization for where you think Node fits, but I don't understand what basis you are making these assertions from, and I'm curious if there's anything to justify these stated opinions.

As for type-checking, there are options such as TypeScript which can be used on Node if a team finds them helpful.
I agree. Even if Amazon doesn't end up launching its own drones, you can be sure that Fedex and UPS will eventually. That helps Amazon too.

Out of pure curiosity, what's a "huge stash" of bitcoins these days? Top 100 on the bitcoin rich list? Top 1000? http://bitcoinrichlist.com/top100

Instead of lending, what about investing in startups using bitcoins?
What about the role of discourse in achieving integration? You mention news organizations and political speech, but those are one-way processes where they talk and you listen. What about discussions and debates between people with opposing views? That's the kind of interaction I'm interested in seeing. Reddit's r/ChangeMyView subreddit comes kind of close, but it's more about switching between binaries than creating some kind of synthesis.

One might think online communities like Reddit would be perfect for hosting these kinds of debates, but sadly people tend to downvote opinions they disagree with, effectively silencing them and limiting the range of acceptable viewpoints. It would be great if there was a solid, popular platform for rational debate between people with opposing views... keeping it rational seems like the hardest part.
So, you switched to which language exactly?
Sure we can follow a good example.
I think you're confusing the two benefits.

What the thread OP is talking about is the decrease in page size from the URLs included in the page source. Choosing a shorter URL for the static domain versus a longer one resulted in a rough savings of 50 bytes per page (size), compressed.

You're referring to request cookie size, which was also decreased significantly (CloudFlare still sets a single cookie, unfortunately), which results in the big savings of ~100 KB upstream per page load.

Great. If you know a little tiny bit about finance then you know that stock prices are not a random walk (with drift or without). A random walk would give you a standard distribution. In reality you are dealing with a fat tail distribution.
And if you provide a charging point and allow the drone to charge, then delivery is free.

I doubt domain length will really make any difference, gzip compression should take care of a longer domain name.
Err, they're different kinds of boundaries.

Photographing every street requires few new techniques. Mostly people didn't expect it could happen quickly or cost-effectively, or didn't expect it would be worthwhile. Arguably, it's still a neat-o factor rather than a core value.

Drone delivery requires a significant number of new techniques.

HN uses the editorial approach to content, figuring that having some people edit user-supplied content will make it more standard and enjoyable, like a newspaper.

I have some doubts about this as well.
Well, that is certainly an enterprise URL.
I never even contemplated the size of cookies before seeing this. It never occurred to me that it could create such an overhead. It'd be incredibly handy if we could set a header like `x-send-cookies: NO` to stop the browser sending cookies along for static content. Great post, a real eye opener.
You can already short Bitcoin; it's been possible for several years on Bitfinex and previous platforms (I forget the predecessor's name).
Ask HN: Is UML modeling before developing software relevant any more?
I am web developer outside of school, and an MIS major in college. One of the main focuses on my major is software analysis and design, were they teach non programmers how to draw UML diagrams to create software.

This methodology seems slow and bulky. Any developers out there able to give some more insight into how widespread diagramming before coding is?
Ok, so let's assume you are right. Did he make the wrong choice? The shorter name seems strictly better to me- whether we feel it is trivially better, it saves traffic and the domain name has lost no information.

If he reworked old code just to save 50 bytes, that would probably be a mistake, but it sounds like the work was being done anyway and he had the choice to save 50 bytes OR use a longer domain name.

Just because someone was wrong about the Wright brothers a century ago doesn't mean that someone else is wrong about something completely different today. Carl Sagan said it best:

"The fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown."
I overlooked the license that would be created for hosting the source internally. That seems like a good route. I also agree that most enterprise clients wouldn't be interested in stealing the source.

It may just be a legal issue, along with a manual process of checking out the code and installing it on a VM they setup.
XFS is better than ext4 when:

1) You need huge filesystems (like 100TB+).
2) You need huge numbers of files per directory (in particular, XFS is much faster at creating the files).
3) You have a workload heavily skewed toward streaming data off the disk.

ZFS does 1 & 3 well. Not as good on 2. And it's less mature on Linux than the other 2. But ZFS also has much more robust data integrity feature than either ext4 or XFS.

P.S. - I migrated most of my stuff from XFS to ZFS this year after many years of using XFS (back when IRIX was a thing).
P.S.S. - Never run XFS without battery backup and make sure to force sync data to disk periodically.
You're absolutely right -- it is negligible. When you're serving upwards of a petabyte per month, 23 GB isn't exactly a lot!

> On the other hand, if saving single bytes was significant, there would be a lot more potential in the source by shortening CSS class names etc. rather than picking a short domain name.

Also spot on, but the point I was trying to make is I was given the choice of choosing a longer domain and a shorter one, and the shorter one resulted in smaller page size, which does result in some (though as you put it, negligible) savings in terms of transfer. CSS/JS refactoring/pruning would definitely be a better bang for your buck if your goal was solely to reduce page weight, but my primary goal was to decrease request overhead and this was just a side benefit at no additional cost to me.

As an aside, I would say the non-technical benefit of the longer domain (4chan-cdn.org) would have been avoiding user confusion, but I feel this is mitigated since visiting 4cdn.org directly bounces you to www.4chan.org and our custom error pages make 4cdn.org clearly 4chan related.

I agree. I'm totally on board that there was some serious negotiation by Amazon (Prime) to get the piece on Amazon Prime Air to air the eve of "Cyber Monday" so you'd see as much Amazon Prime as possible.

I'd believe that it's intentionally out there to put quiet pressure on the FAA to lighten its regulations. I could even see it being run to distract from the Mother Jones-esque pieces about how terrible it is to be a seasonal employee at an Amazon Warehouse.

But this being a reaction to the Bezos book? That seems like a bit much.

Change to IT
In short: Is there a way to transition to IT without dropping everything and going back to school?

Long story: I initially went to college in pursuits of a Comp Sci degree. I had a difficult time and burnt out in one year, switching my major a full 180 to Psychology/Social Services.

I'm now at a non-profit, but it's not what I want to do.

I shouldn't have done that 180. I should have done a "30". But I was young.

I have children and a wife, and going back to school, even part-time, is not an option as I'm already paying off loans. How do I get my foot in the door? I'm not formally trained, but I always fall back into Tech/Computers, and want to do that in my work.
Well, I was assuming that with greater intelligence comes a greater capacity for empathy with less-similar others (e.g. other races, sexes, classes, species), as seems to be on average the case.

Thus, I'd expect an extremely intelligent, rational person to be very concerned for the future welfare of humanity and earth-borne life in general... and then all the goals that come from that would just happen to be extremely ambitious ones.

BTC-e is based in an unknown city in Bulgaria and the operators are unknown. Keep that in mind when trading there.

It's Dan Lyons. He's grasping.

> I doubt he's missed the mark since there's not many other logical reasons for Amazon to announce this possibility five years in advance.

Getting public support early so they have an easier time of getting the legislation passed to make this possible.

Getting public support early so they can get people thinking/accepting of drop off locations in and around their homes and businesses.

Getting people interested in working for a forward thinking company, and therefore attracting engineers wanting to work on interesting things.

But no. It's just marketing hype.

You know what is purely hype in order to get page views? This article by Lyons.

Where To Buy An SSL Certificate
So I'm moving away from using GoDaddy as a provider (thats another discussion why).... so where should I start purchasing SSL Certificates. I can not use self signed certificates.
Huh. Perhaps true. But completely ignorant of the impact, of the size, of the value of what a single "spy" (read also traitor") can discover (read also "reveal").

Spies and traitors tend to discover/reveal HUGE secrets, e.g., how to make a nuclear weapon, how to crack air defense, exact plans and order of operations for critical engagements, etc.

Terrorism doesn't even enter onto the same radar screen as those sorts of things, because all of the terrorism in all of the 20th C amounts to what, the effects of one atomic bomb? (Back of the envelope, not terribly accurate, but gives relevant context.)

I'll stipulate that the vast majority of spies never discover anything useful. I'll further stipulate that "vast majority" involves several decimal points, i.e., 99.999% or higher.

And I'll assert that it is still worthwhile having spies for what the 0.001% or 0.0001% discover - because they don't go for the low hanging fruit, they go for and get the game changers.

X-No-Wiretap header
> If you’ve been linked directly to a Facebook photo, you may have noticed the domain wasn’t facebook.com, but instead something like fbcdn-x-x.akamaihd.net. Large sites load static content from special domains for a few reasons, but primarily to reduce request overhead, and sometimes security.

This works for 4chan, but in case of Facebook, it actually reduces security - since cookies cannot be checked for photos on static domains, everybody can access every photo (as long as they are given an URL), regardless of the photo's privacy settings. In the case of Facebook, they are probably using sufficiently random URLs that mostly mitigate the issue, but a naive implementation could be very problematic.
That really is a terrifying thought if you follow it. It won't be so blatant. Probably more like "everyone knows that Volvo AI's get in way less fatal crashes than "cheaper" Chevy AI's".

Considering human nature, I don't think I can imagine a way where this won't happen on some level or another.
Learn it. Although translating UML into code is mostly a dream from the 90's, it's useful to communicate with other developers at a whiteboard with less ambiguous semantics, as opposed to just scribbling boxes away. The class and sequence diagrams are specially useful.
Yeah, just throwing stuff out there.

One other technique that springs to mind:

5) Set a minimum number of views or clicks a link must get before "falling off." So, if a ton of links are submitted around the same time, sprinkle them back into the mix -- perhaps using a version of Technique 1 -- until they've hit the minimum, then let them die a happy death.
That'd be brilliant.

wtf? yes | sudo apt-get install libpq-dev

The Optimal Post is 7 Minutes
Who cares? It sparks the public imagination and gets people excited for the future. It's the kind of thing that can get a child interested in robotics or can give entrepreneurs a new level of insight into where commerce is headed. It sets a bar for ambition. Also, how often is it that we're dazzled with TED talks showcasing university research projects that promise the world and never make it to market? Is the point, ultimately, to make it to market, or to submit something bold to the consciousness?

Secondly, how will it work out for Amazon, in its coveted "long-run," if it erodes public trust by showing something it doesn't really think will ship? I think showing it in public gives them an onus to execute. As others have mentioned, it also creates an onus for the FAA to take this challenge seriously and to accelerate its thinking about this new direction.
Show HN: Fast filtering of weight loss pictures on Reddit
You're not going to be able to get away from traversing the order book for every match. Another subtle differentiating factor is the time at which the potential matches entered the order book. Obviously priority is always given to price (better price always taken first) but assuming 2 potential orders came into the book for the same price, the one that got there first will be matched.

Another thing to think about is that some firms also don't always want price improvement for an asset. Typically these firms are custodians of other peoples assets and need to trade with equal and offsetting amounts between multiple accounts. If they get price improvement then they end up buying or selling a different quantity which then leaves them responsible for explaining the difference. A lot of times it's just more trouble than its worth.

I think the biggest issue is that the Hacker News admins want to have as few moving pieces as possible. It's why Hacker News doesn't have collapsable comments, why it doesn't have a mobile layout, etc. There's been some tweaks here and there, but I think the biggest change I've noticed over the past ~3 years I've been here is that they removed karma count from comments, and they made the up-vote triangle high resolution.

They seem feature-adverse, and I assume it is because A) Adding more features lead to more causes of failure, B) Front-end/back-end code additions leads to higher page file size/more computation on the backend (meaning higher costs for them to deliver content) and C) the K.I.S.S Principle

Sadly, yes. Further, people dont really care where or how products are made. We get all this negative PR about how appalling working conditions are where many top selling brands are made, but there is no noticeable dent in sales as a result. If shoppers cared, they would shop differently.

However, its a lot to do with the egos of these CEOs, and what not. You and I may not care how nice or horrible these people may or may not be, but the people getting the negativity do. They dont like the idea that the public think they are not very nice, or what ever.

So, I'd suggest its possible its more about individual ego, than sales. Sales is a convenient excuse.
