[Draft] PlaylistsEXT – An extended playlists for YouTube
This could potentially be great news - I've been working on an Uber client app for Firefox OS [1] using the reverse-engineering done by the Uber CLI project [2].

It's pretty a pretty basic implementation at the moment (you can currently book a ride based on an address, and not much else), but allowed me to move to FirefoxOS for my primary phone - Uber being the last 'must-have' app for me that didn't have a webapp version.

Having something official to work with (assuming they don't go down the Twitter route of not allowing anything that replicates the functionality of the main Uber app) would help a lot.

That's another attempt to fix the "representative democracy" crisis.

Unfortunately I saw nothing about "Liquid Democracy" delegations? With pure direct votes only, participation will suffer because voting often on many matters is inconvenient to most people.

The "tagging" of proposals is nice. However, who define the "tag hierarchy"? Is it even necessary to have such a hieararchy, I don't think so.
This is exactly like alibaba in physical form.
My preference is for apps to just have a directions link, and then the various providers can plug into the central OS maps.

The odd thing is that Uber isn't integrated into the iOS Maps app as a transit provider. So you can't actually use it in that fashion.
The could seize IP space using a security system, which began deployment three years ago, called the RPKI[1].

If you use the RPKI to protect the internet against BGP attacks, you provide a technical mechanism which governments, or other actors, could use to seize addresses. I just presented a paper on this[2].

IP takedowns are a risk, the Iranian case is not the only example, for instance RIPE was ordered to seize IP Space by a dutch court[3].

Running that access point at home, or somewhere else, allows you to StreetPass with people who pass Nintendo Zones all over the place.

Ah. In Western philosophy there is talk about attaining 'happiness' or even 'true happiness' but it does not surface much, I am open to correction here.

I totally dig Karen Armstrong, I have two of her books :)

I think Western culture is absorbing these Eastern ideas about not identifying with our thoughts and emotions, that you can acknowledge that 'you' (whatever that is) have thoughts and emotions but that they don't have to define you. I would be extremely interested in seeing if this way of thinking has been advocated in Western philosophy prior to now. Prayer in religion may come close?

An interesting advance on this I have seen recently is the social model of human interaction. By which I mean, we are not a duality: physical and psychological beings but a triad: physical, psychological, and social. To achieve 'happiness' or 'wellness' or 'enlightenment' or 'bliss', call it what you will (I know they are not strictly synonymous) that you'd have to work on all three: the body (exercise or yoga poses or ...), the mind (meditation or mindfullness or ...), society (? charity? other virtuous acts?)

Food for thought indeed :)
There is plenty of evidence, but it would require to change some of our cosmological models (so it's not without controversy). A physicist that has explored the issue in detail is Joao Magueijo:

Seems interesting. IME, This is one of the topics that people who didn't do CS (and even people who did) tend to struggle with and get tripped up on in practice.

Glad to see Dining Philosophers mentioned - it was one of my favorite problems in school and it's a great allegory for resource sharing problems.
Have you had any concerns yet about data provenance? Granted, I've only done queries right on Wolfram Alpha itself (and not with an api), but figuring out precisely where the original source data came from is sometimes pretty hit-or-miss.
Whenever I see functions like these and PostgreSQL's JSON functions, I get the feeling that MySQL/MariaDB is not progressing, or not nearly as fast.

If you had bought the trip you actually wanted to take, you would have paid more. Further, it would have left a seat open on the second flight which they might have sold to somebody else, making even more money still.

Of course, the second flight probably isn't 100% sold out, and you might have gone with a competitor or not taken the trip at a higher price. But they don't necessarily see that, much like music labels don't necessarily understand that every instance of piracy is not a lost sale.

Yes. You can define a special-relativistic momentum and it's a conserved quantity, and it does have a nonzero value even for things with zero rest mass (which necessarily move at the speed of light).

(It may help to observe that an object with nonzero mass moving at the speed of light would have infinite momentum, and then it maybe makes sense that "zero times infinity" becomes a finite number)
Considering that it is quite well done and I have yet to meet anyone who paid for it (aside from myself), I think its going about as well as to be expected.
Google Wants Option to Test Autonomous Motorcycles and Trucks in California
Hmm...

They don't mention the approach I'd take for a naive spellcheck:

Generate a (giant) trie from the dictionary. Then perform a DFS on the trie allowing only <the current closest word's number of edits> edits from the input word, keeping track of the edits done so far - try no changes at each node first, then a deletion, then a change, then an insertion. This works better with a smaller alphabet size.

An optimization: a DAWG is potentially even better space-wise than a hashmap (effectively it ends up compressing the input data), but takes a while to precompute.
Have you looked to see about renting the equipment or finding a service that will help you do this?
This argument and explanation is constantly coming up on the subreddit askscience. I don't violently oppose it as much as some do, since I think it's somewhat helpful, but I would like to say that my preferred interpretation is that a `photon' isn't really a well defined object when inside strongly-coupled materials. For example, can you really sensibly talk about a freely propagating radio wave when its still within a quarter wavelength of an antenna? When atoms are spaced tenths of a nanometre apart and visible light has a wavelength of hundreds of nanometres it seems a bit silly to talk about it propagating freely in a material.

When you go through quantum field theory, photons are defined in terms of freely propagating particles, not interacting with other fields. When the disturbance in the EM field propagates into, e.g. a dielectric material, and strongly couples to various nuclear and electronic excitations, it is better described in terms of a massive quasiparticle, the polariton, which is a hybrid of the photon, phonon and electron fields and, being massive, propagates at less than c. You can, of course, describe it in terms of perturbations to the free photon corresponding to various types of virtual absorption and re-emission, but it's a bit misleading to think of it being physically absorbed and re-emitted with little stopovers. If anything, the classical model of a continuously interacting medium interacting with the EM wave creating a coherent response wave which interferes with and appears to slow down the EM wave is more instructive.

This paper http://www.eecs.berkeley.edu/Pubs/TechRpts/2014/EECS-2014-14... pointed to in the article posted here, claims higher performance per Mhz and lower power consumption than ARM in table 2.

Still, that requires some chip maker to build a SoC around a RISC-V CPU that attains these efficiencies in the real world.

The paper makes these arguments for RISC-V:

• Greater innovation via free-market competition from
many more designers, including open vs. proprietary
implementations of the ISA.

• Shared open core designs, which would mean
shorter time to market, lower cost from reuse, fewer
errors given many more eyeballs3
, and transparency
that would make it hard, for example, for
government agencies to add secret trap doors.

• Processors becoming affordable for more devices,
which helps expand the Internet of Things (IoTs),
which could cost as little as $1

The first point is not very concrete. China has long had some of their own MIPS-based RISC CPU designs, and they are most likely to act on the transparency issue. That leaves super-cheap processors for IoT. ARM may be able to deliver pricing and value that's better than free.

And all this assumes very low friction in the form of, say, Android adding this ISA to the standard set of compilation targets for native code, and, to ART pre-compilation.

Ah, looks like I'll be sticking with my current approach for now then.
It’s hard to say without seeing and hearing about your customers. But:

customers just want lower prices so they try to see if you’re going to cave in with a little bit of pressure. Don’t.

You need to anchor your price to value you’re providing. How do your customers think about the value your product provide? What do they compare it to? Maybe they see you as providing less value than your competitor, if they complain much about it? Can you change their points of reference when they compare your product?

Listen to them, but take what your customer tell you with a bit of salt. They are biased to get lower prices.
I think it works from the other direction. You don't get to say Pi=3.14 and then suddenly circles; the value of Pi is defined by whatever works for circles. Likewise, the speed of light is derived from whatever makes space and time one thing, thus you can't just assign a value to it. The value comes from the underlying structure of theory of relativity.
My biggest frustration with Rails at the moment is maintenance of my Rails apps.

Rails versions come out quickly, and old versions stop being supported. And it's become a non-trivial part of my time running the treadmill of keeping all my Rails apps up to date, along with compatible dependencies.

I realize this kind of goes with the program. Rails all-volunteer development manages to produce a reasonably powerful and non-buggy product that for the most part is constantly getting better; the cost of this is quick evolution and a maintenance burden for users.

I don't think I'd like the tradeoff better choosing a less mature/powerful/robust framework, but it is increasingly frustrating.

(The fact that some of the things Rails adds seem unfortunate to me (turbolinks, spring), can add to my frustration too).

Just a question about the tests:

> the Magnetic bidders were ported from CPython to PyPy, yielding an overall 30% performance gain.

> Memory consumption increased by 30-50% initially, causing slowdown because of swapping on our 16GB RAM machines. These issues were resolved by supplying the machines with an additional 8GB of memory, which stabilized their memory usage.

The 30% improvement is comparing the old CPyton to the new PyPy+8GB, or it's comparing Cpyton+8GB to PyPy+8GB?
>but it never seemed to go much beyond that after it was all over

That's because MOVE was largely hated by their neighbors (who were also black). They were almost universally considered a nuisance to their area, and their living conditions represented a threat to their neighborhood.

MOVE's confrontational demeanor (to cops & regular citizens) combined with building up a huge arsenal made this a pretty unique and delicate situation.

Importantly, Goode claimed full responsibility & launched an investigation almost immediately after the incident which found the city at fault. Civil lawsuits were filed and money was paid out to the family of the victims.

While not normal by any means, this is different from Ferguson in that there, local government seems to be silent and police are treating everyone like criminals, even the press, and are acting with impunity. We've yet to see the fallout though, but it has been going on long enough.
> In Western philosophy there is talk about attaining 'happiness' or even 'true happiness' but it does not surface much, I am open to correction here.

It surfaces more in a religious context; perhaps another East-West difference that is relevant here is the separation between secular philosophy and religion.
I moved away from MySQL a long time ago (to finally get sub selects which weren't supported by MySQL back then), so my opinion might not really count, but usually there's no day passing in which I'm not writing some query using features in Postgres that are not in MySQL.

Could I avoid these features? Probably. At the cost of query readability and sometimes possibly performance and/or server roundtrips.

Furthermore, for years now, PostgreSQL is adding features in places that are very interesting to my use case, so I'm usually jumping ahead to newer versions very quickly.

Case in point is the new jsonb support which I'll be using to displace an old, bulky and join-heavy (performance!) system for handling custom attributes of products and of course, once you've gotten a taste of the awesome, you will never want to go back.

From an operations standpoint, I wouldn't say Postgres is any harder to deal with than MySQL either, especially for smaller setups. Bigger ones are probably similar too, though I personally only have experience with bigger Postgres setups.

There's nothing stopping you from trying it out: At this point, both Postgres and MySQL have proven their reliability even in big setups, so when you start your next thing, you won't ever have to be afraid that your pick of database will cause you trouble later down the road.

As such, I would really stop asking questions and start using Postgres.

Nice!

I've been interested in real ActiveRecord support for Postgres hstore, in a way that can do partial updates -- if only one key/value has changed, on save an update would be sent to postgres for only that key/value. This matters for concurrency issues where multiple clients may be accessing postgres and modifying the same values.

Does anyone know if anyone has been working on that at all?

I've noticed earlier today that a Job Ad posted on HN front-page started higher than usual and moved down much more slowly. Now, it's back at the top, along with another Job Ad. Is this the new normal or just a result of live development?

Also, I'd like to remind all the startups posting Job Ads to HN that this is an international website and that not all its visitors live in <your city> or come from <your country>. Quite often I read Job Ads that don't mention the location at all. For example, while the boostedboards.com Job Ad currently on the front-page prominently displays the location above the job description, the information is absent in the polleverywhere.com description and only visible in the sidebar below the link to the same Job Ad.

100% speedup to certain queries, not all queries. How many queries it covers will depend on the app; as well, of course, how much of app wall time is taken up on queries.

I too am curious how noticeable an improvement this will be in most apps. Is it a micro-optimization that won't be noticed much, or is it actually going to make a difference for real apps?

One use case for 128 bit addressing is for a single-address-space OS running on a cluster. http://en.wikipedia.org/wiki/Single_address_space_operating_...

I'm curious which processors that matter are all RISC. I mean, I realize there are a fair bit of chips out there. I wouldn't have thought many of them really fit the original RISC mold. Sure, they have less instructions than some of the old behemoths. But, that is a far cry from the aims of RISC.

There is also the rise in specialized processors. Combining that with the increased focus on consolidating everything into one chip, and much of the debate is just weird nowdays.
