Yes, just after paying at the toll booth. I am about 99% sure that I used my turn signal, as it is a huge pet peeve of mine, but there is always a chance that I did actually forget, or that I didn't get the lever all the way down. The officer had me come back to his vehicle, in the front seat surprisingly, and questioned me about where I was going, where I was from, where I was coming from, what I did for a living, etc. while he ran my information. It wasn't just friendly banter, it was an interrogation. In the end I received a warning. I had considered complaining when I returned home, but thought it better to let it go. For reference, I'm a mid 30's white male, and I was travelling with my wife and kids in a plain Hyundai Sonata. I've read reports of similar experiences.

Generally because that’s how mathematics tends to work - people publish a partial result & then they or others build on it to improve that result in various ways[1]. The authors are also usually embedded in a wider community of mathematicians who act as a pre-publication bullshit filter by asking pointed questions at seminars & that kind of thing.

It’s quite rare for a genuinely novel solution to a major problem in mathematics to spring up out of nowhere in the literature.

[1] Think of, eg, the Twin Prime conjecture (that there are infinitely many pairs of primes only 2 integers apart). For decades there was no progress on this problem, before Yitang Zhang published a paper last year proving that there were infinitely many primes less than a finite bound apart (70 million in his case). Then a horde of matheaticians attacked the problem using his & other new approaches to progressively reduce that large bound down to the point where it’s now been proven that there are infinitely many primes < 246 apart (according to the polymath group - I’m not sure whether this is a published result yet). The twin prime conjecture is in sight!
Is there any technical significance in the "fade out" sequence that happens between the "F21" image and the next Instagram photo? It looks like once it gets to full black, a few pixels are "stuck" (or slipped I guess), and then something seems to detect that and correct the pixels, so I'm wondering if it's a kind of routine to zero out the pixels, or just an effect. The pattern seems to be roughly the same on each run, suggesting that if it is a self-correction algorithm, it's not persisting the offset/correction (or if the same pixels keep slipping each time, perhaps the algorithm could account for that by rolling those at a different speed).

Either way, this is really cool! I'd love to work on something like this as a job :)
Well, if someone tailgates you, you could just slam on the brakes and let them hit you. To avoid a squirrel, say.

I've actually seen that happen, it was obviously on purpose after a guy was riding someone during commute.
I've been thinking that I would like to get CT and MRI scan done for my whole body, maybe every 4-6 months. Then doctors could keep track of any suspicious lumps, and perform biopsies if they are growing at an unusual rate.

I've read many articles that say MRIs are overused and lead to overdiagnosis. They say that many people have benign nodules and cysts that you don't need to worry about, and you might even end up worrying about shadows or other scanning errors. You'll end up having too many biopsies, which can be invasive and have negative side-effects.

But I think this might be a different story if you could compare two full-body scans, and take note of the differences. In fact, I'm starting to wonder if rich people get this done all the time, and it's just too expensive to provide this level of medical care to the rest of the world.

It's just a fact that a tumour could be growing inside me right now, and I wouldn't know about it until it starts causing side effects. I hope we see some breakthroughs for the early detection of cancer, and I'm really glad to see companies like this being funded by YC.
I completely agree. Real hype is generated when Netflix consistently nails recommendation. Content is still king, but curation of that content is the engine that drives the whole thing
This is a nice PoC tool, but as a checkpointing solution the idea of using ptrace(2) just reeks of being a huge hack.

If you want to do syscall replaying, check out the Approximate Replay-Trace Compiler (ARTC).

Some companies, like Twitter and Facebook, are doing this development pattern of mono repo... So even if there are architectural lines to be found, they are eschewing that in favor of keeping versions and APIs closer together.

I can't say I understand that strategy completely but I have also never worked on machinery the size and complexity of Facebook or Twitter.

Yep, worked. It was the loud/soft dynamics, and the breakbeat/drop.

A lot of techno and big beat stuff is all about that -- I think about Fatboy Slim's "Everybody Needs a 303" (https://www.youtube.com/watch?v=c7iSKMPSwcY) which has several breaks, and even crowd noise at 3:00. He's leaving nothing to chance in that one.

There's a big difference between firing a gun and a car gradually slowing down.

Yes, the researchers could have made better choices. They could have made worse choices, too. The "danger" here is significantly exaggerated given the descriptions of the scenario in the article (gradual slowdowns, contrary to popular belief, aren't that hard to react to in a timely manner), and it certainly does not compare to firing a gun.
Recommending Maclane as the only book on Category Theory is a bit rough. I would add «Conceptual Mathematics» by Lawvere to the elementary list to be prepared.
You got me here. At the time of writing of my original comment it didn't occur to me that capitalism is an example of a game thst doesn't set the rules to level the playing field. I guess I was thinking about games with well-defined victory conditions and relatively short play time.
The Americas cup had rules about boat configuration. So technology started driving the race. There was in the 1980s the australians showed up with a secret weapon the "winged keel" on the boat "Australia II". It helped a lot and raised the game for yachting.

https://en.wikipedia.org/wiki/Winged_keel

1988 rolls around, and a New Zeland team is trying for the cup. Giant boat. US shows up in a catamaran. Catamarans are just faster..
The boats don't even seem like they should race.

Long timescale atomic simulations of liquids is a really challenging problem. Most of the well developed accelerated dynamics methods only work well for solids where there is a well defined time scale separation between atomic lattice vibrations and reactive events. In liquids (e.g. protein folding) the timescale separation is not as well defined. There seems to be complexity at every level (vibrations, small rotations, dihedral angle changes, etc). Liquid like systems have a very rough potential energy landscape with an enormous number of shallow minima that must be explored to understand the dynamics.

I look forward to the clever algorithms that will be developed that will enable modeling liquid systems on the experimental timescale. This is recently become possible in some solid-state systems, but it will take some time and effort before it happens for liquids. Then it will be much easier to do first principal studies of organic/bio chemistry.

8:42: You ok? (An apparently conscientious and concerned question from the police. Good, but too bad he doesn't stay like this.)

8:53: (Irritated, but civil response, by the accused, detailing why the cop is being a dickhead.)

9:15: (Cop doesn't like that he's being called out on dickhead moves and the tenor of the conversation changes. Cop proceeds to use his higher standing to escalate the situation instead of deescalating.)

You're missing the change in the cop's mindset right before the "asking about the cigarette." If the cop actually felt confident about why he pulled her over, he would have been able to handle how she responded. Instead, he felt threatened by the questioning of his motives. Why didn't he articulate the full reason and purpose for the stop right then and there? He decided to continuing escalating, and that is primarily on him. He could have slapped the ticket into her face and walked away.

Also, he wasn't bothered by the cigarette until he perceived an affront to his authority. That's childish playground behavior, not an attitude befit a public servant.

5-6 car lengths on a wide open road is an instigation. If a non-police officer driver does this, you wonder to yourself, "why is this guy up my ass?" This isn't some densely packed freeway, and he's 5-6 car lengths behind her. Why do that?

iOS 9 is pre-release software with an expectation of changing APIs before it releases. So makes sense for them to have a hold on iOS 9 focused updates till release.

Yes, biological research requires a lot of infrastructure and laboratory set-up, so it is indeed expensive. However, YC is an amazing platform to get your technology off the ground and in front of customers. In addition to the funding, advice from YC members has been invaluable in getting a strong business strategy.
> It's always a shame to see HN act like you scale vertically and magically every problem is solved.

When this is seen (and IME it's a pretty minority opinion) I think it's there as a reaction to the massive overuse and hype regarding a lot of newer-gen DBs. There's absolutely no doubt that there are good uses for them, but those cases are pretty niche compared to the level of their uptake.
This is a much longer topic but it boils down to 2 things:

1. Switching your database is not easy with or without stored procedures because it will involve down time for the application while the data is migrated, then verifying that it works as expected in the new database with that ORM. You hope for the best, but it's always more complicated to switch a database.

2. The ORM tends to lock you into the application stack. Switching a part of your application from something like Rails to Go when you need to performance tune is significantly easier and more common than switching the entire database backing the whole system.

Beyond those two are the harsh realities of working with large datasets. As soon as a dataset it non-trivially small relying on the application to do core work on it becomes self destructive by adding network latency and in many cases object creation (check some Rails benchmarks on object creation costs). It becomes a big deal.

This is not to say that doing the bulk of work in the ORM is bad or that everything should be done in the database, it's a matter of balance. The only dangerous opinions on the matter are the "purist to the detriment of all else."

Verifying uniqueness, exclusion and maintaining data integrity should be the job of the database in most cases. That is what it's good at. Performing actual business logic on that data should not unless there is a significant performance based reason for it in most cases.

In Postgres the "stored procedure" thing is a little bit different because they're significantly more valuable thanks to the volume of functionality built into PG. Everything is basically a function in PG.

In PG, you can use functions to create indexes and when the function is used in a where clause that index will be used. You can use functions to create constraints, unique indexes and even notify outside process that are listening of changes in the database with pubsub.

PG is a heck of a lot more than just a "datastore" and that's why these discussions are important. If you want a generic dumb datastore...there are databases built for that. PG is built for a whole lot more than that.

Here's a very incomplete summary: http://www.brightball.com/postgresql/why-should-you-learn-po...
You're striking at the core of the issue here.

In RMS's ideal version of the world, there is no distinction: every "user" is also a "developer". The freedom guaranteed by the GPL enables society to reach a state in which every individual is not merely a consumer of solutions, but a producer. In this vision, we all cooperate to solve problems together because solving problems in the world makes the world better for everyone.

In reality, problem-solving ability (the intersection of the cognitive ability, skill set, drive, and opportunity to solve problems) is a limited resource. There are problem solvers and there are sheep, a configuration that results in a natural kind of economy. "Corporate" with all its lawyers and sales hucksters, i.e. persons not directly engaged in the work of solving problems, are a necessary demon. They connect problem solvers with users that have problems to solve. Users, for their part, exist to give us their money as a reward for the work of solving their problems.

Whether to support the GPL is really a moral decision about which world you believe in. Do you solve problems to make the world a better place, or to make more money for yourself? I personally wish RMS' vision would come true even though I don't believe it's possible. There are natural limitations to problem-solving ability other than the psychological effects of the capitalist environment on those who grow up in it. Still. When you really dig to the bottom of opposition to the GPL, you always find one thing, and one thing only. Money. "ME".

This is great to hear. Sometimes people just don't know any better.
So, she's making faces and is angry, and that's your greenlight/"difference maker" for the cop to give her a ticket? Wow. This is exactly the "playing nice" game that I've described in a cousin thread.

If the cigarette is such an issue, why didn't he ask her that before she rebuked his grounds for the ticket? He's power tripping the whole time after she hints that she's not pleased, and you're greenlighting his power trip because she wasn't a bootlicker.

This is victim blaming at its finest... she's rightfully angry, and you're saying we can't blame the cop for not keeping his cool?

Which index? If it's an S&P500 one that's 500 stocks to buy. What happens when companies enter the S&P500 or exit it? You would need to trade again which means more commission fees.

What if one company in the index grows considerably while another one falls in value? Do you rebalance between those two? More commissions. Index funds hide all of this and I would guess it winds up cheaper particularly if you include effort.

Any significance to a guy from SETI being in the conference?
Our platform is a cell-based laboratory tool where we reconstruct the environment of human organs in a dish. When cells are placed in these physiological conditions, they behave the way they would behave in the human body (unlike the conventional models where cells are grown on a surface of plastic dishes). Such set-up allows us to evaluate how cancer cells will respond to drugs (or drug combinations) under native conditions of drug-resistance. I.e. when cancer cells interact with their environment in the human organs, this environment protects them against chemotherapy and other drugs, so when cells are taken out of their physiological environment, they become more sensitive to drugs. This results in a false assumption that the drug has anti-cancer activity, but when it's introduced into a patient, the drug doesn't work.

What we provide, is a system where drugs can be tested under the conditions similar to those seen by the cancer cells in the human.

What we are offering right now, are services to test drugs in our system, and we are gearing-up to provide all-inclusive kits that can be used by researchers to run these assays in their own labs.

Please let us know if you would like know things in more detail.
I haven't looked into in a while, but from what I remember it lets you say whether you are interested in categories of content and not specific content.
A bit off topic but I often think about if we developed the technology to simulate in real time a mass of about 4 pounds and the technology to do a cat scan (or something similar) with atomic granularity. We could sort of cheat when it came to AI and just take a human who already knows what we are trying to do, scan him, and simulate his brain. Never the less it seems we are very far from that possibility.
Coming from the old world of business IT where "integrate everything with the relational database" is standard procedure, it's certainly not unusual for the database to be a place where abstractions are defined(1), so what you expose via PostgREST may not in fact be a close match for the underlying data model.

(1 - In fact with me it's pretty much a matter of policy: any external system should access data via views named for the external system. Then, as inconvenient as it sometimes is, Postgres' dependency mechanism will keep me right about which fields in which tables are depended upon by which external systems.)
That seems like a huge leap to a conclusion with the parent comment doesn't substantiate (without more information). Just sayin'
Apple is just nuts. This makes me glad I don't have anything to do with their ecosystem.

It's very hard to be the "Lord of the Castle" and not end up doing something that seems crazy and unjust to someone. This is especially true in the face of numerous attempts to exploit and mobs of the noisy clueless. Even if you go to the trouble of instituting some sort of sophisticated judicial process, someone is going to cry "foul!"

The above can also be taken as an argument for why one might want to avoid being part of the "ecosystem."
Exactly. The player moved the Bishop diagonally, but unless they understand why they moved the Bishop that way, it feels like they're cheating.

Seems reasonable to me. They are presumably blocking app updates that take explicit dependencies on new/changed APIs in the preview. If they allowed apps to take dependencies on these, they'd effectively be forced to support the API surface exposed in the preview indefinitely. (Alternatively, imagine the outrage when they broke a bunch of apps with the final release.) Disallowing this enables them to iterate on the preview more effectively, which is the entire point of the preview.
The other side of it is that the entire enterprise would theoretically not exist without that initial effort.

While it may not appear fair under certain ethical frameworks for someone to receive free money, it seems to be that the choice is "everyone gets nothing" versus "someone gets more than others because they created it".

in my experience, this is a red herring. I know very few founders who don't work harder after an acquisition or capital investment than before. Those who are sitting on the beach tend to have sold their interest.
