That's the assumption anyway (cp already works that way); we're talking about this only because the OP had hard links everywhere.

> /tempdir/$inodenumber

That's what I was talking about in my former post. This does use resources: the folder "tempdir" takes up additional space (it is in addition to the file's content, inode and the other paths). It either needs a b-tree, hash-table or similar in kernel space (on disk, and cached in RAM). Every entry needs to store $inodenumber (which you should mean to be the inode number of the source file, not the target, because you need to map from the source inode, so you can't even argue that it is stored anyway already), plus the storage in the index (b-tree or whatever that makes up the directory listing), just like the user-space solution, but additionally at least also the length of the file name and the actual inode number of the target file.

You're not better off (almost surely worse), and you can't get around the fact that the basic algorithm, which is copying every file while walking through the source tree and checking it immediately, is what is at fault: it needs random access (every iteration needs a look up to a random spot), which is why RAM is required and any kind of disk access (be it swap, or just reloading directory index storage from the file system) is out.

That's why I suggest to use a different algorithm. See my post about "megacopy". That should already be usable by now, BTW. It has a --tmp option to give a non-default location for temporary file storage (used for the linking table), you can point that to a place on the target file system or wherever else you like, which I think should answer your call for resource limitation. How well that algorithm (sorting (and linear append and read) instead of random access) works with regards to RAM usage, I still have to test.
These regulations were put into place after the products were released. I don't see why this should be any different.
That sounds like the way all traditionally "scheduled" services work. That's what makes me wonder about this model. A scheduled service is just not the same a ride.
Governments will pay you if the cost of your preventative treatment is less than the cost of providing state welfare. Don't assume that the public has to pay from their own pocket, they can pay you through other means. Government grants are often sizeable and under appreciated.

Your pet issue has little or nothing to do with Alzheimer's. Alzheimer's results from a combination of three things:

1. Amyloid plaques forming between brain cells.

2. Neurofibrillary tangles forming in brain cells.

3. Loss of brain cells, likely from the build-up of 1 & 2.

All three of these things happen to everyone as we age. This is true no matter how good your immune system or diet is. Many of us just get killed by something else before it becomes pathological.
Yes, that was our main reason for joining BizSpark, to be honest. We're a "pure play open source" company and absolutely favor running on OSS / Free Software platforms, and we encourage people to fun our products on Linux, a BSD UNIX, etc. But, in real-life, Windows, Office, Exchange, Sharepoint, etc. are out there, close to ubiquitous, and sometimes you have to work with that stuff. So BizSpark is a great way to get your hands on all of the MS "stuff" for testing, integration, etc.
Definitely, there is no such thing as an objective truth when it comes to things such as these. But it is possible to reduce the chances of abuse of selective enforcement and prosecutorial discretion by passing laws that are as transparent as possible and by having little to no career effects as a result of such selective enforcement if and when they take place.

Otherwise you make a law for Al Capone and you end up prosecuting Aaron Swartz.
> Granting the inventor a monopoly costs more to society than it benefits the inventor himself.

You cannot make that assertion without empirical evidence. You bring up good points about the costs of patents, but note that your language ("can", "could") is all in terms of potential.
The studies I've read consider all those points and then try to quantify them, even going as far as seeing how they play out in different industries. Other studies raise points which show the benefits of patent systems (increased R&D spending, increased diversity in the areas of innovation, increased probability of securing VC funding) and quantify those too. Other studies actually find counter-intuitive results about monopolies in general (e.g. monopolies can be more innovative than startups by some metrics -- think Bell Labs, Xerox, MS Research -- which casts doubt on the "monopolist gets lazy" argument). There are tons of studies presenting interesting results, and of course, there are studies that point out flaws in these.

The problem is, it is impossible to compare these results quantitatively because the data, methods, assumptions, interpretations, shortcomings and metrics are wide, varied and often orthogonal. How can you meaningfully compare a lower rate of stitch / minute improvements (that was used as a proxy for the cost of sewing machine patents) with the increased diversity of industries participating in a technical convention (which was used as a proxy to measure the beneficial effects of introducing a patent system)? And to top it off, both studies were by the same author (Petra Moser)! This is just one example -- there are as many metrics as there are academics researching this area.
This is the first thing I thought. Given a sufficiently large city and a sufficiently disinterested friend group I think it's possible to pull this off in many places. I have friends who have grown up in New York and never been to the Met. I'm fairly certain I could convince them I was at the Louvre.
"Advancing the state of the art" like all things in patent law, was deliberately broadly written because there are thousands of ways to do so and infinite multitudes of nuances to consider. Fairness absolutely was, and always has been, one of the main points. In fact, all property rights concern fairness, and intellectual property rights are no different.

This could have done with a lot more explanation. The link is for a (already 180% funded) Kickstarter for "Stuff and Nonsense" which is a successor (remake? sequel? "This game has a similar story, but the rules are almost completely different.") to an older game called "Captain Park's Imaginary Polar Expedition" from Cheapass Games, in which the basic concept is that you and your friends are all faking expeditions with game mechanics around a) faking evidence and b) catching your friends faking evidence.

You can download "Captain Park's" from the Cheapass "Boulevard of Broken Games" at http://cheapass.com/node/115 which basically has downloads for games that haven't been updated in 10+ years.

I've only heard of one agency-specific product out there... but the name escapes me. Will try to search for it.

As far as differentiation, there are some services with unique features and some that are offering good products for free, no string attached (restrictions on message history for example). I would check out Kato (kato.im) and if you are more interested in a "Twilio for chat" try Layer.
It would be awesome if this product was actually a giant sting operation designed to identify people who have no business being on the road.

Again, you're going symptomatic about the disease... The premise that we live longer than ever before and that's why we get these diseases is a statistical error. Child mortality and poor record-keeping was driving life expectancy down. My own homeland had a lot more centenarians in the past than in the past decades, for example. My own predecessors lived longer than my relatives who died recently of various chronic diseases.
We are already living in an ecological catastrophe. Humans are currently killing off ~20,000 species per year compared to the natural rate of ~1-5. (estimates vary widely)

Though, we could probably survive just fine even after killing 99% of all species on the planet so this might not be that bad long term.

It's the same thing used by Google Glass, and other head-up displays (like the ones built into airplanes and high-end cars). I believe it involves collimation: https://en.wikipedia.org/wiki/Collimated_light

There was an article the other day posted on this. It operates at 24 and 60 ghz whereas most RFID is in the UHF (900 MHz band). This radio harvests energy to run an oscillator and actively transmits data whereas RFID only reflects back power (no active rf transmission). Also, this device require a fairly massive (42 dBm / ~20 watts rf) for a few cm operating distance compared to RFID which achieved several meters of distance using 36 dBm / 4 watt transmitters. The biggest achievement is the size reduction. In the previous HN thread, someone poured out that this is academically very interesting, but probably practical.
Erdős: Mathematical problems
I just tested this, the parallel updates and installs are fantastic, however, I have "YouCompleteMe" as a plugin, and it consistently fails to install, and when it tries it seriously lags out. Vim will freeze for 4 or so minutes, and it fails with an error "fatal: destination path '~/.vim/plugged/YouCompleteMe' already exists and is not an empty directory"

Something strange there. Trying to resolve it, I don't doubt that there is maybe something I neglected to do, but that's not a black mark on me, vundle has no trouble with this, and doesn't complicate it either.

So cool project, young project, if I can resolve the issue I'll definitely be using it.

edit: Wait a minute, miiiight just be YouCompleteMe.

edit2: noooope, vim-plug installed YouCompleteMe in such a way as to mess up the repository. Manual installations work fine.

The photo on their home page shows someone reading an SMS, not watching a video. The SMS is from someone recommending a video, but there's no indication that you can actually watch the video while you drive.

It's a poor choice of image, though obviously they were just trying to embed the "Hey, watch our video in your browser" instructions into the photo itself.

Aside from that, even reading SMS while you drive seems like a bad idea to me. But I'm really tempted to get a Navdy for features that improve safety, by moving stuff that I already look at (speed, navigation) from my dashboard to the HUD. I've been shopping for cars recently and wishing that HUDs were available in more affordable models. I just hope you can turn off Navdy's text/call notifications and other extras.

Something like this will be good enough to get an idea if you like the sport or not, and is a fraction of the price.

http://www.eriksbikeshop.com/Specialized-2014-Hardrock-Base-...

Many bikes in this price range have similar frames and components. The components won't last as long as on a better bike, but will be good enough to get you started.
After that you pretty much get what you pay for in improved components. Its like buying a computer - the more you spend the better components you get but the higher you go, the less gain you are likely to notice (unless you are really pushing limits).

If you are keener to commit and spend a bit more trail centres should be able to rent you a trail bike.
"Catalysmic Variable Star" is a good name! :)

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

Both of the stars stars are white dwarves, a mass of a sun squeezed into the size of a small planet. With a 17-minute orbit, they're incredibly close: one of them is ripping the atmosphere off of the other. Helium from the lighter dwarf is being pulled off and falling onto the more massive one -- pulled so strongly, it impacts the surface at several percent the speed of light. A helium layer builds up, at temperatures and pressures close to that of the interior of a hydrogen bomb. And at some point it does go off, like a hydrogen bomb -- a thermonuclear detonation the size of a planet, the entire surface igniting almost simultaneously. And this keeps repeating!

I hate to see products like these promoted because the creators are making bloodmoney.

Cell phones are not dangerous because the driver was looking at his phone or playing with the buttons when he had an accident. They are dangerous because they encourage your mind to wander. Most people's brains are really not good at multitasking. (Try patting your head while rubbing your belly counterclockwise)

Anything that takes your mind away from the road when you're driving even if you can see the road is dangerous. (They found that talking to someone in a passenger seat is not as dangerous because if they notice danger and you don't, they'll inform you of the danger automatically by tensing up or whatever.)

If your brain worked like a single process cpu, it would be like setting Twitter to high priority while relegating driving your 2-ton SUV to low priority. It will work well enough most of the time, but sooner or later, you'll crash the SUV.

You obviously get my point though. Exceedingly poor choice of front and center image to use.
You've listed three examples of products that changed the world, and have huge utility despite their danger. The main advertising for this product, however, seems to be that it allows you to tweet while you drive. So I don't think it's a very fair comparison.
> Well, a ban on refined starches and corn sugar work quite well. People were much healthier (from an obesity perspective) when such products were not available.

Do Scotland, New Zealand, Hungary use "corn sugar"? We don't use it much in England and we (along with those other countries) also have problems with obesity.

I'll happily accept that calories from sugar are a problem.
