> Can you tell if the pump is dispensing the octane rating you actually selected or a slightly lesser-quality fuel?

Isn't that true for any conceivable gas station, from the most laissez-faire to the most centrally regulated? Unless you can physically perform the experiments required to test the octane rating yourself, the only thing you can do is trust. You either trust the reputation of a gas station or gas station chain which you frequently purchase from (and have had no previous issues with their gas), or the reputation of some third-party consumer review organization in a laissez-faire economy, or the reputation of the government regulatory agency in charge of gas stations.

In all three cases, the organization you are trusting has some incentives to lie/cheat, and some incentives to be honest. Deciding which system has the best incentives on net, and thus is the most trustworthy, depends on the details of how each system works, and is a nontrivial economics problem.
Cullen Murphy and one other writer from The Atlantic wrote a book (unless it was just an article) about the notion of "neoteny", the preservation of juvenile characteristics into a mature age. They noted that among North American wildlife the tendency increased as the animals were further from their (presumed) original range. The biologists argued that the younger traits added to the adaptability of the animals and enabled them to thrive in conditions different from those of their ancestors. You could make an argument for the uses of neoteny in the software business.

(I once amused an (extremely grown-up) immigrant acquaintance by proposing this as the explanation for the immaturity he saw in Californians, suggesting that the Eastern US was the home range of the American. But of course he saw Americans as generally immature.)

I do not blame anyone for enjoying it when his chosen work makes him a lot of money. I do not blame any man for aspiring to attract women better looking than he is. (And I think you mean "entitled", in which case, No, nobody's entitled.) But yes, a little consciousness of what it's about wouldn't hurt a bit.

> The standard of "objectivity by media citation" breaks down for many fields of study

To me, this isn't a problem with Wikipedia specifically, its a known feature of tertiary sources. (And its really not specific to any particular field of study, its true everywhere; its one reason that, when I was in secondary school, encyclopedias were considered a useful research tool in much the same like, say, a very heavily annotated general-purpose bibliography with a subject-matter organization, but not citable directly for information (except in the case where the information was the fact that something was presented in a certain way in the encyclopedia in question.)

> For one example, there are many criticisms of Wiki history in /r/AskHistorians.

I'd be surprised if there is any publication concerning history which would not have many criticism if you asked a wide and diverse group of historians about it.

> It's about as livable as a kid's tree house.

http://3.bp.blogspot.com/_copRHv93JEI/SrlhWCKPSVI/AAAAAAAACf...

Not exactly a kids version but quite livable. And I think this house is meant to make you think, it's a reductionist view on living rather than a complete replacement for all the amenities that we take for granted.

Running water, toilets and insulation are not present in plenty of the houses in the country where I currently reside and I can see a kitchen added in there or in very little extra space.
Fingerprinting is fine; but the actual value would come from a large database of all sorts of fingerprints, so it could be used to identify songs, snippets, movies, etc.
No giant bookkeeping datastructures that end up with the process thrashing in swap, because tar is designed to work with so many files that you don't want to keep the metadata in memory.

I have only recently found a position where I feel I might be a A minus fit. Being a B player sucks - especially if like most other b players you are trying to hide it.

In fact I would say hiding B player dom is the thing most likely to prevent getting to A. The problem is very very few environments allow one to make as brave an announcement as OP and survive with salary intact.

I think probably the best means to build a team of A players is to allow people to admit they are B players.

It should work much better provided you can easily divide it into batches where you know they don't have any shared hardlinked files. Otherwise you will duplicate those files wasting some space. That may be fine as well though.
True, but if you were somewhere where data was unavailable or you didn't want to use a local data connection, it might be a nice way to force a map app to update to your current location, get an email, send your location to somebody, or answer a chat message.
FFS Thanks
I have no idea what complex would be in your case but adding game-like animations to a view with auto layouts would probably not be a good idea.

But the whole point is that auto layouts from IB can be controlled from code as well so you don't have to write the code for the auto layouts completely in code. Writing auto layouts in code is laborious and it's easier to make mistakes.

So if you "park" a low priority constraint for the end point or even the points in between you can let them take over by changing priorities only. Also you can animate most other properties as well if you need it.
Don't read the article provided too carefully. The image isn't a CT and has been dumbed down from the source. The image is an MR not a CT, and the image below is some sort of made up composite image. Original source with proper images: http://brain.oxfordjournals.org/content/early/2014/08/22/bra...
Should we change the URL back?
Not much of a trick, the first tar serializes the entire directory structure including all the metadata into a stream of bytes, from which the second tar reassembles it.

Basically the same as tar's standard usage, except you don't store that stream as a tar file/image anywhere.

How about this for a better cp strategy to deal with hardlinks:

1. Calculate the hash of /sourcedir/some/path/to/file

2. Copy the file to /tempdir/$hash if it doesn't exist yet

3. Hard-link /destdir/some/path/to/file to /tempdir/$hash

4. Repeat until you run out of source files

5. Recursively delete /tempdir/

This should give you a faithful copy with all the hard-links with constant RAM at the cost of CPU to run all the hashing. If you're smart about doing steps 1 and 2 together it shouldn't require any additional I/O (ignoring the extra file metadata).

Edit: actually this won't recreate the same hardlink structure, it will deduplicate any identical files, which may not be what you want. Replacing the hashing with looking up the inode with stat() would actually do the right thing. And that would basically be an on-disk implementation of the hash table cp is setting up in memory.
I don't think you can actually call this "FOSS". The project has changed licenses twice, from GPL2 to Apache [1] and then from Apache to some weird "dual-licensing" scheme. [2]

The current license claims that the project is available under the Apache license, but only for non-commercial purposes. Frankly, this does not make sense, since one of the benefits of the Apache license is that it allows commercial use.

So it's a hash table that's about twice the size of physical memory. The entries in the hashtable are usually pointers to memory that you need to deallocate (char* filenames in this case, maybe some other stuff too) so if you're a good citizen you iterate through them all and deallocate (mark is as free) them as you go. It would seem there were some pathological swap issues doing that. It would be interesting to see if a tree behaved better in this type of situation. The allocator has tables of its own in memory too, if you have to swap those out to find the memory that your then going to deallocate then swap out all the user data structures to swap in the allocator's structures to do the deallocation or something whacky like that, it kind of makes sense.

His patch just skips that step and ends the program.
"The following images depict opening up and messing with a 275 volt DC power system. It will be exposed, be unfused, and be extremely dangerous. If you touch the wrong spots, you will commit suicide instantly. If your metal tool touches the wrong spots, it will explode in a plasma cloud and deposit itself on your face."

Love that warning.

"Do not look at it funny or it will explode and you will die."
Probably not particularly well. It's based on the variations in pitch over time and unfortunately the human voice fills a very narrow frequency band. Maybe you could limit it to focus on that area of the frequency spectrum to get better results but I suspect it would require more dramatic changes to get good results.
I don't think it matters that the Apple watch stands the test of time, the thing about tech is that you can't create "timeless" tech because it will become outdated in a couple of years. The watch will be replaced the the watch 2 so I don't think people are really thinking about this purchase being a long-term investment.
Trigger Warning: Memories of reading about Plan 9
While I appreciated your principled stance I believe it is more of a graded issue and one with several practical steps in between that are all 'freer' than the previous step.

- matlab + windows + CUDA

- octave + linux + CUDA

- octave + linux + Free OpenCL

So you're halfway there and it could be better but it could also be worse.

Writing a very high performance piece of software against a bunch of trade-secret grade hardware for which the manufacturer already provides a bunch of support for many people is not worth the trouble. As long as Nvidia supports their hardware using CUDA and OpenCL is not going to be brought up to that level this will likely continue.

A positive view would seem to me that this midway position will allow more people to move to Octave which in the longer run might free up some funds somewhere to tackle the problem you mention.
IBM’s proposal for an Internet of things architecture using block chains
Whenever you get to extreme cases, there's always going to be something subtle. I'm sure he didn't google " how to copy files", but looked for people who'd worked with many terabytes of data. Reminds me of a nice story by Reginakd Braithwaite: http://raganwald.com/2013/03/26/the-interview.html
It is generally superior because it can skip blank blocks. RAID is byte-by-byte.
A corollary: everyone detests looking like his father, nobody minds looking like his grandfather. My brother and I would not under any coercion worn shorts with dark socks and dress shoes, as our father routinely did in warm weather. Some kids don't mind that now. Think also of the "Teddy Boys" of the 1950s, wearing the clothing of the Edwardian period ca. 1910.
The system would slowly leak memory until you reboot.
It's more than just strings though, it's all lists on a set of atoms. (a b c) is treated differently from (a (b c)).

EDIT: Actually you're right, it's all strings on X. I thought the author wanted all lists on X.
XFS really shines when you're dealing with large volumes, especially with RAID. There are certain features, like striped allocation, that mean you end up getting faster performance, because the filesystem has a better idea of how blocks are laid out on the disks.
That's part of what it means to look good.
You're quite correct that the market is much broader now - not only are there more consumers, there's more developers.

But to me, this doesn't feel different - just larger.

Even the cycles seem to the same - with early adopters leading the way, the first wave of quick and dirty apps, then more polished apps, and then the tsunami of shovel-ware that kills the market for newcomers.
Less code is a good thing! I hope you fire up Xcode to see with your own eyes if the code-only view looks okay as well?

Also it's much more documenting to they guy that's going to maintain your screens later on.
Thanks, I appreciate it! Yep, we have everything extremely well documented already for the next owner. All the ordering procedures and customer service routines are documented and ready to go!

How does this happen?
10^31 different positions is no closer to infinitely many than 5 different positions.
You can use fdupes (or various others similar to it) to find and automatically hardlink the duplicates.
it reminds me of crash only software.
At these elevated voltages the currents are manageable. If this were a 24V pack then your concerns would carry far more weight.

The biggest issue is vibration loosening a connection in the longer term but there are plenty of time-tested ways to avoid that from happening.

Even fork lift battery packs (which can carry immense currents) are still built using the crimp terminal/bolt through method.

It's not building codes. It's that as soon as you have something that resembles a bona fide home, it becomes legible to the legal system, ownership is claimed/assigned, and then its occupant is on the economic treadmill of the debt-based financial system (or they are forced out).
On the other hand, Leica and Hasselblad switched to digital along with everyone else. There's still a high end but it has to compete on technology, not just exclusivity.

Watch purists may go the way of vinyl purists, slowly dying out as the competing technology offers more and more convenience.
Isn't it a terribly inefficient design to malloc hash entries individually? It would make more sense to use a pool / arena for that.
If there's no charge for the first two weeks, why make me enter my payment information? Just lock me out after the trial's up - if this works as advertised, I'll plunk down my dollars in a heartbeat.
The dual licensing scheme isn't that weird, specifying different licenses for different uses is quite normal.

Also, the Apache license covers plenty of commercial cases, as the terms[1] state, it's only 2 very specialized deployments that require a non-free license.
Given that 99.x% of deployments and users fall under Apache License v2, I figured F/OSS would be an accurate description, even though the "F" doesn't apply to 0.x% of cases.

Still, I don't want to misrepresent the project, so I will rethink my statements (especially in the website)in general.

I worked on this too a few years ago. There is a massive patent minefield out there, including this algorithm.

We were doing recognition of TV shows where you are holding a cell phone in your hand some distance from the TV. A prototype with this algorithm was okay, but very easily confused especially as the number of items in the database increases. You also end up with a lot less amplitude at that distance from the TV which makes the source messier. In theory phase shouldn't have had an effect, but in practise it did so things had to be run multiple times at different offsets to improve matching.

Our final algorithm was way better. It was based on what audio codecs do. It even worked reliably with a 60db signal while there was a 70db interferer signal!
That was one very quick trip to the recycler, pack dates from August 2013. Crashed car?

Totally nuts to work with DC voltages this high without taking safety precautions. Anything over 50V DC is to be treated with very serious respect.

AC is different, you get a good number of opportunities to dis-engage, but with DC your muscles contract and that's that.

I'd rather mess with 2 KV AC than with 200 V DC.

Lovely engineering on that pack by the way, the number of safety features is very impressive. Sure looks a lot better on the inside than mine ever did!

I think the MOOC still has potential, but it needs to follow the same evolution as the rest of the internet. The trend over the last decade has been to put the power of creation/production into the hands of everyday people, not the few elite who control the means of production. Notable examples would be YouTube, which allowed people to do from their bedrooms what only television and movie studios did a generation ago, airbnb, which lets anyone be a hotel, Uber, which lets anyone be a taxi, WordPress, which let anyone publish online, Amazon or Ebay, which let anyone sell online, Wikipedia, which lets anyone edit the encyclopedia.

I think the true power of the MOOC is not letting Stanford teach the world, but letting the world teach itself.

The difficulty is that you are using a filesystem hierarchy to 'copy files' when you actually want to do a volume dump (block copy). Use XFS and xfsdump, or ZFS and zfs send, to achieve this.

Copy with hard link preservation is essentially like running dedupe except that you know ahead of time how many dupes there are. Dedupe is often very memory intensive, and even well thought out implementations don't support keeping book keeping structures on disk.
this is great! i was just starting out on a project in which one component was to recognize gunshot sounds from varying distances.
For one it makes automated leak detection tools like Valgrind useless.
It was not my intent to dismiss anything, but derefr didn't address these issues. I'm glad that someone has spent time thinking about this stuff, but no possible solutions were mentioned.

I also agree that a government isn't a simple cure, but a government can definitely enforce things better than a free market. As a hyperbolic example, if I use slave labor to cook meth to sell on Ideal Silk Road 2.0, my worst case scenario is losing my business - with a government, my worst case scenario is fines and decades in prison.
Others have already mentioned that it isn't really necessary, but for some historical context this wasn't always true. When I first started programming computers, apps (written in languages that aren't garbage collected) on your typical consumer level computer/OS had to be really careful with freeing up all allocated memory before exiting or that memory would be gone forever (as far as the OS was concerned when it came to reallocating it to other apps) until the user rebooted the computer.

Advances coming from the combination of more advanced operating systems and CPU features like MMUs have made this a non-issue in most cases (can still be an issue on embedded, etc).
Really awesome hack and can't wait to see what you guys do to improve it!
I agree. If there's a bug here, it's in the server which collapses slashes seen in request paths, not in the indexer's interpretation of robots.txt.
Isn't this notionally true of IP as well?
I don't think the problem here is functional programming, it's the author's over-eager use of category theory to describe something simple. In particular we're just talking about all possible lists you can create in LISP, so do we really need to resort to free monoids? The language of category theory is greate for describing complicated structures like tensors and sheaves and what have you, but in this example it's not really helping.
