This is insanely cool. I do game dev for a living, and pathfinding is one of the biggest hassles.

Right now, it's in a weird spot where it's sort of free, since you can offload to other cores that would otherwise remain idle. But as Mantle and other multithreading APIs take off, and engines get smarter about multi core, it's going to go back to being a big bottleneck.

This is the kind of thing that could create a truly EPIC game.

Well banks used to use gold as an asset and then give loans on top of that, nothing stopping anyone making Bitcoin IOUs on top of bitcoin holdings. The problem is the same that was solved by banks hundreds of years ago, why would someone store gold with them instead of storing it at home, replace gold with bitcoin in previous sentence ;)

Anyways this might explain Goldman Sachs involvement, when one puts bitcoin into Circle you do not control the keys (the "gold" is no longer yours) you get a Bitcoin IOU and you put your trust in Circle, down the road once Circle have millions of users they could offer a lending service and/or make it easier for people to get into stocks (and hence Goldman Sachs profit) and other investments

Politicians can be forced out of office for anything. It's called elections. Most countries also have some kind of impeachment process.

Are you saying politicians shouldn't attempt to do what their constituents sent them to do, under the penalty of imprisonment? Minorities are protected not by politics, rather by judicial review, which worked great in this case.

I don't see the political monoculture mentioned in any analysis about Baltimore, New York, St. Louis, Detroit, etc. These cities have been basically one party rule for fifty years (or more). If the police become too brutal or incentives become perverse, the party is not thrown out of office. If the mayor or council members are shown to be corrupt, the party is not thrown out of office. There's no real accountability.

To be clear, I don't think the problem is unique to big cities. Political monoculture certainly happens in rural areas, but the tragedies out there (even more extreme poverty, lack of opportunity, population decline, meth epidemic) aren't seen as acute for whatever reason. I do think the problem is that, at some level, you can't credibly say "You messed up -- the other party gets a shot at running things" in much (most?) of the country.

To some degree, the problem is the two-party system. If the district is liberal (as is the case in Baltimore), there needs to be at least two credible liberal alternatives. Maybe it's time to consider making room for more parties, for the benefit of local communities if nothing else.
I agree with letting the interview know you are interested in their company. Inquisitiveness is a key character trait we look for and asking intelligent follow up questions is a great sign rather than someone that has just thought of a list of pre-canned questions beforehand and is going down them.

But I wouldn't view letting on about other interviews a major problem -- knowing there is some competition both ways isn't a bad thing. I want great candidates to work for us, but I also know great candidates have choices.

For practical purposes I don't know anything about encryption; I'll just get that out of the way now.

The parent warns against messages with similar formats, exchange of pleasantries or signatures. In particular, it warns against sending HTML-formatted data (e-mails).

Encrypted data is sent all day long, with message contents in HTML format over SSL/TLS.

Would this article be better named "Good GPG Encryption Practices"?

-If so, could GPG be improved to share the characteristics of SSL/TLS or does it already have that support with some message types?

-If not, why don't we see more attacks on HTTPS traffic?

Cool project.

I'm somewhat surprised that they didn't end up using an Open Street Map derivitive. If Google was good enough, then they'd probably find something from Mapbox or others that use OSM data acceptable, and many provide tools so that "the additional work to custom style the maps would be extraordinary" wouldn't be true.

It's also a bit wierd that the comparison screenshots are all at a different level of zoom from the one's that he wanted to use. Many online maps emphasis different things at different levels.
I would argue in this case that people simply need to plan a bit more around the inherent frailty of humans.

You can have supply teachers on call. Or you can pay them a bit extra to arrive early and mark work in that time. (e.g. make the actual working day 5-6 hours; other hours used for marking, planning, etc). There are other solutions.

One that sticks out in my mind is that when I used to work retail, our hourly pay stopped when the store closed. Obviously you don't and can't leave then. The last customer is slow, you might need to lock up, etc.

In most cases, all you need is for management to actually think about these issues and to not allow the quest for margins to result in abusive practices.

When you're a contractor then yes, you are The One, you have chosen and need to be reliable. When you are part of a massive organization with profit in the billions (e.g. a supermarket), it really is a deliberate choice they are making which results in stress being loaded on you.

Ask HN: Is this idea for audio compression technically feasible?
I have a great idea for an audio compression algorithm, but does exist already? And if not, is it technically feasible?

My idea is that you take repeating identical sounds/frequencies (kick/snare/hi-hat/bass etc.) and encode them as the "same" as the first occurence in the song. That way you would save a lot of data/space, especially with electronic music where many of the sounds actually are 100% identical along the song.

But would this work in practice? Or would it be too complex to find out what is truly identical and what is just similar, but not similar enough to be marked as "same"?

I would love to hear what HN has to say about this. Thanks!

Are you suggesting that elections should give people a status that puts them beyond the countries constitution?

Remember that these principles are so general, they must apply equally to Western politicians pushing security policies, as to e.g. Muslim politicians in Egypt or other ME countries pushing for Sharia-inspired policies.

What their constituents want is a nice idea until this violates the most basic rights of citizens spelled out clearly for this purpose, i.e. to guide and limit any future laws.

That being said, there is always the possibility of revising the constitution. Even if that is not a good idea. But for good reason, that is a lot more difficult to accomplish.
I agree wholeheartedly.

My standpoint is that by developing on someones platform, I am doing them a favor. I'm happy for them to not roll out the red carpet, but there better not be a bouncer checking me at the door, either.

If I have to sign up to used your SDK (unreal, unity), I'll just use something else.
Maybe there's a market out there for "ghost developers", i.e. programmers who manage activity on the Github accounts of other programmers, the aptitudally-challenged types who need them to cheat interviews as they hop their way through technical jobs on their way to a career in IT management.

Just sayin'..
Yeah, legalizing heroin is not going to fix the problem, medicalizing it might cost a lot, and you won't be able to compete with drugs dealers. Users might buy from dealers anyway.

If you want to remove the dealer's profits, you have to compete with drug dealers, but it has to be healthy, you have to treat users and remove the incentive to use drugs, and it's a very tricky thing to do.

I really don't know how to do this, but it boils down to the same problem of unemployment and crime. How do you integrate people into a healthy social model ? Poverty and economic opportunity is still at the root of the problem.

I think it really helped that they attached themselves to the "elite status" of ivy league universities / Harvard at the beginning. Those have worldwide recognition, so that when they eventually expanded beyond .edu, it still had some of the Brand value of those institutions attached to it, "the smart/cool/rich students of ivy league universities use it, so it must be good", something like that.
I personally don't use debugger that much but whenever I have used it, I have always been amazed at VS's debugger capability. I don't think I am exaggerating when I say that VS has the best debugger across all languages/platforms. I think this is a GREAT news for all the developers.
Then let's focus on making it actual damage rather than potential damage. Whether financial gain is considered is a separate issue.
Microsoft is a software company , so i would guess their end game is not services or hardware but software. Anyone got any ideas how they plan to dominate the software world and make money out of it? They 've just gained a ton of new fans though, that's for sure.
No, I didn't try to optimize this any further. I just checked whether any of the new interpreters is really faster. It's a simple one-off experiment, and compared to real statistical machine translation with Moses on the same data the translation is pretty much instant. Moses needs something on the order of 1600 CPU-hours (50 nodes * 8 threads * 4 hours).

That was 2001. There was no SAS loophole to exploit. If you desired to sell software, you had to ship it. In a box. The GPL was as viable for businesses back then as the AGPL is today.
Probably not. Just like there has not been a new IBM, Microsoft, Google or Facebook. New things will dominate new areas, not compete with existing giants, until they're quite large already. Usually, at least.
Yes indeed. We handled goto into do-while statements wrong. Fixed now. Thanks!
Agreed! If a developer has a github account, then they're thinking about some other programming thing on the job instead of the cruddy stuff they're being paid to do.
5 Principles That Drive Social Commerce
Even assuming you weren't effective - why would anyone care? At all?

Unless you are heading to a meeting instantly or opening the store or whatever, why does 5 minutes matter? Why does 10 minutes matter? Even 10 minutes every single working day shaved off would be <= 2% time lost. It really is negligible.

You're not going to suddenly turn around your productivity by adding a few minutes to your work day. Most of us spend more than that making coffee.

Gazette Herald – Potassium Intake Is More Beneficial Than Low-Salt Diet
We've seen a few grid A-star/grid-based pathfinding articles and tools now and they're really interesting but every time I see one I can't help but think, "how is pathfinding done for games which are not a grid?"

For example in an open-world type MMO or FPS game position is a floating point number. Does the game engine break the area down into smaller polygons?

If so is that mesh 3D? If so what happens if something isn't at the appropriate Z-axis? For example if AI is chasing a player and the player jumps how does the AI know the human player is on the same plane? And how does it differentiate that from the human being on another ground level slightly above/below it?
The licensing model is another thing that is going to be a big issue as the world moves into the cloud.

So far, many of the big names in FOSS, such as MySQL, have been using GPL to their advantage. By forcing competitors to release their modifications under the same license, GPL grants the copyright owner an effective monopoly on proprietary features. RMS probably isn't very happy with this situation, but it works.

GPL, however, is nearly useless in the cloud. You can add features to a GPL program and offer it as a proprietary service running on your servers. Since you're not distributing the program itself, you don't need to open-source your changes! AGPL was designed to prevent that, but hardly anyone uses AGPL.

Moving in the other direction are LGPL, BSD, MIT, and a bunch of other "permissive" licenses that are getting ever more popular among the cutting edge of the tech scene. In an ideal world, this should lead to even more freedom and better tools for everyone. But we don't live in an ideal world.

RMS has a knack of saying seemingly outrageous things that turn out to be highly relevant 10-20 years later, so I wonder what consequences the current proliferation of easy-to-convert-to-proprietary-software licenses will have on the tech scene of the next generation. Will all the good features get locked into walled gardens, or will companies continue to see value in releasing code under a permissive license?

Today's FOSS culture didn't arise on its own. It owes its existence to a dedicated group of people, such as RMS, ESR, Linus, Red Hat, MySQL, etc. who provided a large and stable copyleft core for the rest of the ecosystem to revolve around. But if the cloud makes the copyleft core largely irrelevant, how will the rest of the ecosystem adjust? Will it even survive? I don't know.

It's not putting them above a constitution. There is a process in place to resolve constitutional issues. In this case it worked perfectly.

Punishing people merely for passing a law would itself be unconstitutional. There is no enumerated punishment nor is there any reasonable way to assert culpability.

p-values are extremely useful for two things:

1. Teaching people who specialise in context areas (chemists, engineers) a pragmatic way to make a decision from data in the presence of randomness.

2. Automating analyses. (remember your Benjamini-Hochberg)

I'd never actually use it myself. Jeepers, just look at the picture.

It's probably worth noting that--primarily in denser locations--the rapid delivery of goods is already a thing. Delivery of papers by bicycle messenger (although that has declined), takeout delivery, grocery delivery (which has been around for a long time in many cities but has been getting more systematic with services like Instacart). Of course, there have also been massive failures trying this in the past like Kozmo.

I suspect there's a complicated relationship between density, profit margins and overall cart value of what's being delivered, price sensitivity, and other factors. It obviously does work in some domains and those who already have established something that could form the basis of a delivery infrastructure may be in the best position to experiment further. It won't work for everything or everyone but if fast delivery works for food for example, there's no inherent reason it shouldn't work for a lot of other goods that people can't get easily delivered today.
