I don't think we need worry about comment fragmentation on posts that have few points and no comments and are more than a few hours old. The odds of new comments appearing there are minuscule. On live threads, yes, but we often move those [1].

We do give originals another shot, by rolling the clock back on them internally, if they're up to a few hours old. Beyond that, it feels weird to have a story on the front page with just a few points and a timestamp that says e.g. "23 hours ago", let alone "163 days ago".

We don't change the user-facing timestamp, because that feels like rewriting history, the sort of thing that HN users wouldn't like. It would also make /newest look weird as neighboring posts could then have different ages.

The repost invites don't require users to come up with a different URL. You click on a link and the software fills that in for you.

Probably our next step will be to add a setting to user profiles that people can turn on if they want the software to do such reposts for them automatically. In that case, no need for an email, plus the software could pick a good time to do the repost. On the other hand, it's already clear that many users like getting these emails. The positive feedback has been striking.

An open question is what to do in cases where the submitter has no email address in their profile, or doesn't check their email.

If you or anyone knows of a more elegant solution, please tell us! We would love that.

It's a shame that the ASCII file, group, record, and unit separators that have been around since forever did not catch on.
A paper earlier this year at Usenix entitled "The Bugs We Have to Kill" takes a similar position: https://www.usenix.org/system/files/login/articles/login_aug...

In fact, djb quite famously identified parsing as one of the major sources of vulnerabilities, hence his devotion to formats like TAI64, netstrings, cdb and use of the file system namespace where sufficient.

As a trained, but non-practicing, physicist, I would like you to elaborate about your first paragraph. I am used to using units where c=1, I think that is what you are referencing: a "meter" of time is the time it takes light to go a meter (which is to say, a very small amount of time) and so a second is 3x10^8 m. I don't see how this changes the pattern we would make in spacetime. If we assume no one ever moves (a nice physics-y approximation), but the particles that make them up do, so I don't see why we wouldn't look like the middle pattern while alive. Then after death, the disintegration is exaggerated, but again, it seems more-or-less right to me. What am I missing?
I am glad they didn't shut down access to java and mysql. But after your and pgaddict's comments I did a little browsing and see what you mean. They haven't exactly been stellar.
You won't give up your cushy tech lifestyle to feed starving african babies, but you expect a blue-collar worker to give up his job to feed a guy in Dehli?
I think I must be misunderstanding.

You talk about "decentralizing" but you mention Google Apps for e-mail and Medium for a blog. If you want to decentralize, you should be running these things on your own server(s) that you control.

What am I missing?
It's "boring" for the same reason people get "bored" in buses, subways and trains. That doesn't mean they don't use those because they are boring. If it gets 3x cheaper to travel by self-driving taxi vs driving your own car, people will choose them in droves.

In fact, look at self-driving taxis or cars as your personal and private "bus" or limo, if you will.
Traffic and vehicle speed are two different things. Slowing cars can be done without slowing traffic. Traffic is limited by the carrying capacity of the road. More, but slower and smaller, lanes can handle the same amount of traffic while still slowing cars. Simply halving the number of lanes (4 to 2) without replacing the carrying capacity, only offloads through traffic to other areas. It would be better to replace the one fast+big road with multiple slower and smaller roads.

And the bike lanes in the OP are awful. Those bikes don't want to share pavement with moving cars. Put that lane on the other side of the parking lane, preferably with a line of grass/trees shielding it from moving traffic. That keeps everyone happy.

(Those painted green lanes are also a horror for motorcycles in the rain. They must turn, lean and accelerate all at once on that wet paint when entering such a road.)
No. To mention a few, Xerox had a verb-object interface (you selected 'Copy', selected what to copy and then where to copy it), not the object-verb one, didn't have the concept of dragging, didn't automatically repaint partially uncovered Windows, didn't have a laptop with a keyboard that's close to the screen so that you can use your palms to prevent it from falling from your lap, and didn't do a click wheel or a touch screen. Xerox also, AFAIK, didn't do a hockey-puck mouse or a phone that bends :-)

What makes you think so?
Thanks for htop!
I'm sure it's just Mom's taking kids into their home to make some money on the side. They're making less than minimum wage and aren't accounting for any rent or supplies, but it's better than the nothing they'd get staying home to look after their own kids.

My point doing the math was that a day-care as a "real" business has to charge at least double the OP's $350 a month.
Ask HN: API for people data?
I'm working on an application that will rely heavily on public record data. I've secured sources for the majority of the data that I need but I still have to find a provider for people data. I'm looking for basic background information on individuals like: age, sex, current residence, marital status, and phone number. Nothing too fancy.

I see that there are a few data brokers out there like Axciom, Datalogix, Intelius, and LexisNexis. Anyone worked with one of these companies before? This is a bootstrapped project so where can I get the most bang for my buck?
Need to Lose Some Weight? Get a Fitbit
Yes, there are nuances that most people, myself included, don't understand because we have not used it extensively. This is human interaction with physical objects; there are literally infinite possible nuances.

It doesn't take much effort to look around and see people comparing this to a long press and totally missing the point. I think the pace of Apple's marketing video confused many. So, again, first-hand experience is necessary for me to take any assessment seriously.
The CP is discussing basically prototypes/schemas (essentially; schemas are debunked now but they're useful for understanding by analogy how connectionist cognitive models work); I don't know of any pop science books ala Thinking Fast and Slow about this topic but it's not hard to research. I would start with schema theory and other derived memory representations, the TRACE word recognition model, semantic networks, and neural networks.

PsychInfo is probably the best database for this, if you can't get access to it I'd recommend using google scholar and libgen.
Actually, you may want to cut the time step as well, so it could be a 16x computational requirement.
For starters, I don't think there's any conceivable risk of boxes on supermarket shelves being stuffed to the brim with cocaine.

If you want to look at the number of cumulative life-years lost to drugs vs. sugar in the past several decades, my intuition is that it's not even remotely a close contest.
It's selfish to ask us to overlook the needs of the people who make their homes in a place for the benefit of some few who choose to pass through.

That may be true, but it's also selfish for people who inevitably travel themselves as part of their own lives to expect everyone else to behave differently. The degree of NIMBY thinking in the setting of public travel policy is one of the biggest problems we have with making progress.

I saw some interesting but all too predictable research not long ago. It was about people who campaign for heavy restrictions on driving in their own (often expensive, desirable, close to local amenities) area, such as lower speed limits, traffic calming measures, extra crossings, or even closing roads to motor traffic entirely. A remarkably high proportion of those same people, when covertly observed, drove their own (often expensive, powerful, inefficient, dangerous) vehicles in exactly the kinds of ways they cite as objectionable in their own back yard, as little as a half-mile down the road going through someone else's residential area, or past someone else's kid's school, or on the way to some other local shopping centre.

So, there is certainly a lot we can and should do to improve road safety, but like administering first aid, it should be based on evidence and real need, not who is crying the loudest or making the most emotional appeal for help.

Unfortunately a lot of the time these kinds of travel infrastructure decisions are made at a very local level, in response to very local pressure from relatively small numbers of very vocal campaigners. Local politicians with the authority to make the decisions are, in practice, more accountable to a few hundred people living within a mile of their home than they are to national governments and their evidence-based policy frameworks and even well-funded research organisations. Consequently, the number of people effectively influencing policy on their own doorstep may be far less than the number of people actually using that travel infrastructure every day, but the latter don't get a vote and so the systemic bias frequently results in effects akin to a tragedy of the commons. Maybe it's different where you are, but in the UK this happens very often and very obviously, and it's a real problem.

People adapt. If a person decides that a trip is too expensive, they will find another trip that meets their needs.

Or they'll stay at home and let their kids watch TV and play on their Xbox.

If a business loses some customers from outside it's neighborhood, then perhaps there will be an offset from within.

If this really happened very much then it wouldn't be local businesses who are usually the first and most vocal critics of travel-hostile changes in local policy.
This is a personal account of my success with my Fitbit. I also try to explain how the Fitbit makes weight loss sustainable through rapid feedback and the idea that "frequency reduces difficulty". If you already have a Fitbit and want to make better use of it, this might be helpful to you.

> It's kind of a weird argument to act like abortion isn't core to Planned Parenthood.

No, the weird argument is "We shouldn't fund Planned Parenthood because they provide a legal service we don't like."

Same sex marriage got here eventually, the legalization of marijuana will come to pass across the entire country in the next 3-6 years, and abortion too won't be fought over as soon as more conservative voters pass on (which no longer necessitates a republican party that must cater to its extremists).

Conservative talking points and beliefs are almost like zombies; dead, just not knowing it.

Ah, the glory of unrequited love, always so much better than the real thing where we have to deal with their literal and metaphorical dirty laundry. In the absence of actual reality, we get to imagine them a perfect being. We get to fill in the blanks with such fierce emotion and lofty assumptions about someone we never really knew.

The beginning of the piece has such wonderful and evocative detail, it is either a genuine memory or well researched fiction or some mix of the two.

Unlike other cynics here, I don't think it can be easily dismissed as merely "Wow, our gonads sure drive us." But then I believe we are spirits in the material world and I have been sustained through many hard things because of strange and kind encounters myself. Edit: Also, my father and ex were both soldiers and I have known many military personnel. So, there's that.

It's not wrong, and I didn't downvote you, but I'm not sure we need to concede that anything more difficult than "read numbers from /dev/urandom" is required here. :)
> Why should the former be associated with a "quick peek" and the latter with a committed selection, rather than vice versa?

So you think Apple et al should completely upend the entire interaction model of iOS i.e. make clicks force touches and vice versa. That's an interesting take on introducing a new input method.

> Seems like there could be more ambiguity there than there was in the slow-single-clicks vs double-click problem.

One of the commentators is right. You really need to use the feature.

There is very little ambiguity when you try it especially when the haptic feedback reinforces your action.
I wasn't saying that reducing our ability to travel is actually better. I'm saying the cost is less than it might appear. People who have to plan their shopping trips a bit more will still buy almost as much stuff. Or they might go to a local store in walking distance (increasing demand for very local businesses), or they'll order online.

Similarly, adding a new lane to a highway doesn't help traffic as much as you'd think, because it generates more trips that were probably fairly marginal compared to alternatives (since they didn't happen before).
Most of the Katrina damage was due to Army Corps of Engineers failure in the decades preceding it.
A: Which was my point... Just because memory isn't reliable doesn't mean telling something in detail from memory is a tell-sign that it is fake. It just means that those memories could be wrong or, subconsciously, made up.

As I said, I just wanted to comment on that. And that because of the way you gave the memory the benefit of doubt, considering the circumstances anything else could have been equally suspicious.

Also, it's not hard to imagine he doesn't really believe he'll find her and typing it up serves a purpose of its own. It could also be something he just wanted to share.

Again, I'm not saying it's real, just that I didn't think the arguments I commented on was particularly convincing. Sorry?
Inertia, Communication, Noise.

The landscape is very different from what it was in 70s. They were working on a clean slate before half of the human population had computer terminals in front of them. Their battle was to get the terminal in front of people, but I'd argue that the biggest accelerator to adoption has been social media, not the way GUIs behave or programming languages function. The web is now the legacy software we're stuck with if we want any impact at this scale.

Say for example, if you had a completely new idea for a general purpose operating system which simplified things greatly, but was unlike Unix, and it had no web browser. Now what? People aren't interested - they want their web browser.
For a game, fine, donk around with your own CSPRNG implementation; for real-world apps, please just use /dev/urandom.

The overwhelming majority of RNG disasters in the past decade have come from userland CSPRNGs written by people who were wary of urandom.
I'll buy that your spacetime braids disintegrate at death altho i'd think they be more like the parallel braids of a stone, not like those shown helicoptering out as in the picture.

But as for birth, clearly your start branches off of the braids of your mother. and so start immensely tangled to begin with.

You realize what happens when "Big Soda" declines, right? "Big Water" is next, and with that, privatization. GIVE THEM FAT KIDS.
Well, some people will always want to smoke and eat poorly, and that is their choice. But cigarettes were never really insidious in the same way something like "sugar" is; I think sugar will have to be seen as a vice rather than what it is, one of the cheapest sources of calories you can get kids to eat. And that's going to have to take some deep change in the market.

And sports drinks, energy drinks, and flavored waters are certainly part of it.

Personally, I'm a big fan of soda stream. :)
I dislike this being described as smarter. So far, what we've seen as described is behavior that is more predictable and consistent. In the scenario described by the OP, in which the car slammed its brakes because of a jogger on the opposite side of the road...that doesn't strike me as a decision based off of what we'd traditionally consider "intelligence", but a strict adherence to a set of rules that could use a little more refinement and complexity.

In a way, the rules are a kind of "codified intelligence", and a computer that follows them can be said to be smarter, at least if we defined that based on the results, eg. "able to take a better path to achieve the same goal" (in that case, hurting less people).

Even if self-driving cars do dominate future roads, it's going to be an interesting few years of transition...human drivers are going to quickly realize that their automated counterparts are almost always going to follow the rules, allowing humans to cut them off without worry...Maybe at some point, these incidents are going to be logged as evidence (using dashboard cams that are almost certainly going to be standard on all driverless-cars) to prosecute those overly aggressive human drivers?

Maybe, but there's also the 'glasshole' effect - others drivers will already be anxious about driveless cars, you don't want to add reasons to make them angry at them as well.
Yeh, I realised that, hence my apology. But IBM's involvement with the Third Reich is an example where the nightmare of data retention leading to mass murder has already happened.

Every time you tick the boxes on in the equal opportunities compliance area you could be setting yourself up for disaster.

If you were a Ugandan student in Britain in 2000 you might have ticked the "[ ] Homosexual" box and had the nightmare of The Uganda Anti-Homosexuality Act, passed by the Parliament of Uganda on 20 December 2013 with the death penalty proposal dropped in favour of life in prison. [1]

The calories don't have to be replaced with anything - total intake can be down even if obesity is still rising, obesity will just be rising less than it otherwise would.

Also the obesity rate in children is down, which is encouraging: http://www.cdc.gov/pcd/issues/2015/15_0185.htm
cheers matanster, appreciate the note.
Re: ripping out libc, the folks at https://gandro.github.io/2015/09/27/rust-on-rumprun/ seem to have had success in replacing Rust's libc usage with their own restricted implememtation, and have expressed interest in providing a fork of libstd that bypasses libc entirely and just does raw system calls (which itself probably wouldn't be useful for your purposes, but at least proves the concept).

3D Touch is completely different to the MacBook's Force Touch.

It's the combination of (a) the effect of pushing through the screen, (b) the haptic feedback when you do so and (c) the way the UI responds to it i.e. by blurring the screen.

Your argument is akin to saying you can appreciate music by reading notes on a piece of paper. Physical nuances can rarely be explained in words.

It helps that we were so far from either side of the war. We could build huge facilities like that above ground and just camouflage the building where Germany would have had to build much more fortified or even underground facilities.
If you look at what the bond markets did in the period preceding World War I, you see that they did not predict it. Thinking that markets value risk correctly leads to disaster.

I think we've swapped notes on a similar thread before, so we may have already talked about this, but let me say that if you liked Permutation City by Egan, you may also like Glasshouse by Charles Stross.

I also "second the motion" in regards to both The Selfish Gene and *Gödel, Escher, Bach".
Because some humans will still be better at some things than some machines. It's not all black and white. There will be degrees of wealth as there are now.
Even self-driving cars aren't perfect. The reason you don't cut in front of a human driver is because human reaction time is finite and you're likely to get hit. The same goes for a computer driver - it has a hard limit on how much it can track and if you happen to cut in front when it's taxed... you'll get hit. You're still gambling on the other driver noticing you on time and hitting the brakes.
I'm studying topological quantum computation, and in this field one considers particles confined to 2 dimensions called anyons. As a collection of anyons move around, the paths they take in spacetime "tangle together" and have the structure of an element of the braid group (https://en.wikipedia.org/wiki/Braid_group). Two anyons cannot exist at the same place and time, and thus their world lines cannot pass through each other. This is useful, since any sort of physical error in the system will preserve its braid structure, saving the need for quantum error correction.

This article is mostly fluff (except for the two diagrams, whose captions contain more content than the article), but I'm sure it makes an interesting read for those wishing for light philosophical thought rather than deep and novel technical concepts.
