I use it to store a lot of historical time series data that doesn't change once written (at least, not often). I can easily achieve the write performance necessary to record the data streams live. Since it's all append-only, I don't need to worry about fragmentation. With replication, it's possible to access the data with very high throughput which is useful when the data is being accessed by a cluster, for example.

I also use it as a metadata "scratch space" for highly available applications (things where failures are not acceptable and must run for days at a time). Again, with replication and automatic fail overs, I've been able to maintain 100% uptime outside of maintenance windows. Obviously that can't last, but so far it's been >2 years with no major problems.

EDIT: I should point out that although the size of the metadata objects can be highly variable, since I usually had a small number of them relative to the time series, fragmentation was still not an issue.
It's not a big hassle at all. The system is already managing payments as a queue, and once your meal is paid for (either because you paid it or because you were a beneficiary of someone else), the next one on the queue is the one immediately after you, which the cashier can then take your payment for and clear it out of the system.
Stream logs to Square's Cube - log^3
You have a smallish number of documents where some particular field of fixed size gets overwritten a lot, the old values are uninteresting, and it wouldn't really be a tragedy if your data got trashed. For example, it's the player's score.

You want a fixed-size, rolling backlog of time series data such as logs.
That's exactly right imo. Running MongoDB in production, you end up concerned over the performance of each query (as you should be). MongoDB's profiler makes this easier to investigate.

If you hit a db level lock limit, you're probably running a sub-optimal or unindexed query.
Lovely but nothing very new. Does your IDE also allows you to poke around local variables and the call stack while changing code in realtime?

You can read more in-depth evidence in the book, "The Greatest Show on Earth. Evolution is not a hypothesis, it is a fact. It's not even debated among biologists. If you have some evidence against it (or for creation), submit it to a peer-reviewed journal. If you can throw evolution into question, you'll win a nobel prize for sure.

> Attempting to use MongoDB in all storage or persistence scenarios is no more sensible than using MySQL in all cases.

Substantially less sensible in many cases. MySQL has its issues (it has a lot of issues), but people have been able to get it to work surprisingly well in roles that it wasn't designed for (albeit sometimes by just building a database on top of it, as with Twitter's thing).
So, what's a good NoSQL database for e.g. node.js use? The only alternative I know of is CouchDB. (Yes, I should give more parameters about the intended use, but I really don't know any alternatives).
I Eventually Managed to Leverage My Wave
Same experience here. In one case where there were missing components from a 3rd party order the Amazon rep. sat on the phone with me as I picked out individual replacements which they shipped to me at no extra cost.
I specifically address this point when I say that it's only a minority of people who would even remember that controversy. Would you care to address this line of argument?
Good to know. I actually ran into that with a flashlight the other day. Prime product, but a lot of the recent reviews complaining it was a chinese knockoff. Caveat emptor.
I have, but thank you for bringing up something incredibly obvious and well known. Honestly, perhaps I shouldn't have feigned confusion in my reply. I just felt that it was courteous to have them reframe their question again before I concluded that they really did miss the point completely.

My point was that pen and paper, itself, is not a sufficient model of computation (it is not capable of any computation). Pen + paper + human is. The fact you mention is precisely why I chose to bring this situation up. If we throw in humans to the mix, our candidate "model of computation" can become heavily reliant on the capabilities of humans. At this point, we need to explicitly say that we include human interaction in this model. Based on my standards, this is not a really fruitful statement, since humans are almost capable of general computation alone. They just need the memory. Analogously, pen and paper is just a work tape. a work tape is not a system or automaton at all. I find it mind boggling that I have to explain this to people, especially those who appear so confident that they understand theory of computation.
Matterhorn (a mountain in the Alps) mapped by fleet of drones in just 6 hours
The normal way of displaying the ip address for HN is `184.172.10.74`.
You then just have to take each 4 parts and multiply it with a power of 256:

184 * 256^3 + 172 * 256^2 + 10 * 256^1 + 74 * 256^0 == 3098282570
To be fair, even PayPal screws up recurring billing.
what's an example of a type of programmer not considered good?
http://7393249866/ doesn't seem to work in chrome as it doesn't believe it's a link. Entering it directly in the URL-bar doesn't work either.
All of the others is shown as `184.172.10.74` on mouse-over.
That makes the restriction odd to me. If they ported win32, then why are they not allowing 3rd parties to use it? There are only a few of possibilities to me:

1) They want to influence developers into doing new WinRT apps.

2) They are trying to keep good relations with Intel.

3) They want an explanation for why some popular software doesn't run on the arm tablets and saying it can't is easier than saying it "just doesn't".
I see this trend in other industrialized countries, like in western Europe. I believe probably a very important cause of this demographic imbalance is the equality factor. Women work same as men, earn same as men and feel empowered. This is great for the individual, but then the society as a whole remains out of equilibrium.

For some reason being independent (able to buy what I want, when I want it and work 20 hours a day) is better than rising a family and having children. Things that are after all, the reason of what as species, are suppose to be doing in this planet.

The signal is then clear, you fail to do that, but being to extinct. This is exactly what begins where this trends are prevalent. Perhaps we need to rethink the roles and if being independent is something that in the long term will create more value for the group.
7393249866 mod 2^32 is 3098282570. I'm not convinced you can do that - although it works in Firefox, telnet and ping don't like it.

Edit: I highly doubt that this is standard behavior. I suspect that implementations that permit this are storing the number in a 32 bit integer and not checking to see that it was truncated.
Except we're talking about structures where there is no management to speak of. If there is strong management, they can just tell people to work on those things as part of their job. I suppose you could extend your idea to a loosely structured company where incentives would be created through consensus.
No, what they thought they wanted. They promised a world without DBAs, but the "DBA" is really, whoever gets called at 3am in the morning with the site goes down. If you don't know who the DBA is, it's you. They promised a world without schemas, but you always have a schema, the only question is whether you know what it is and the tools help you validate it or not. They promised massive scalability, but really just pushed scalability problems out into other layers of the stack. I could go on and on...
Thanks, man. I had the same problem.
When people claim they're legally "obliged" to enforce their IP, they're saying that if they don't enforce it, it could possibly be argued that their ownership rights are diminished because the work was orphaned, just as abandoned physical property can lapse to the city if the owner is absent and the property unmaintained. They're not actually "obliged" to do anything with their property.

Most of the time that argument is a convenient cop-out. You'd have to abandon your trademark pretty hard to lose the rights to it; leaving a few obscure online projects unmolested won't matter.

The real deal is that companies are very protective of their IP because they don't want anything to potentially impact their brand(s), and lawyers are eager to bill for as many hours as they can. It's possible that IP owners could commit a small team of goodwill ambassadors to filter alleged infringements and send licenses instead of (or quick on the heels of) C&Ds to good projects, but who's going to do that?
Sorry, but the global write lock has been public knowledge since the very early days. Mongo's done nothing to hide that. Also (i worked for 10gen at the time) the "marketing department" that you refer to, was a single person organizing events to give developers what they wanted: knowledge and a community around mongodb.
It's important to make the inner workings of our tools visible and understandable, so that we can make the right decisions about them.

In this case, this article does nothing but elucidate the truth, quite plainly and clearly, in fact. That's important, in and of itself.

Spammers dodging Twitter’s DM URL bug by sending links to tweets
1) There are certain things that click with the majority of the HN audience (or at least the ones who up vote) and the weekend hacks go into this category

2) HN is unpredictable and some luck is involved. If you get a couple of up votes from people early, you are more likely to get more clicks from the /new page, which leads to more upvotes... Social proof, kind of.
The last time this came up on HN, I decided to dig into ping and glibc's resolver stuff to find out exactly why this worked.

This brings up an issue related to Wikipedia's policy that requires substantial third-party coverage for new articles. It is a flawed test for the importance of a subject.

I don't think it's best interpreted as a test for the importance of a subject, although I'll admit that some Wikipedians do view it that way, and some policy pages (especially older ones) seem to do so as well. To me the more defensible line is just that it's a test of whether there exist sufficient sources for an article with its information properly cited to be written at all. If there are halfway decent third-party sources, one can be written, of some kind of level of quality, transitively dependent on the quality of those sources. If there are no decent third-party sources at all, then there is no basis for writing an article, since Wikipedia articles are supposed to be verifiable, i.e. everything they claim should be cited to something other than Wikipedia itself (and not the personal knowledge of the Wikipedian who wrote the article, either).

I wrote a longish essay arguing this in some more detail, that the 'verifiability' guideline has basically swallowed the 'notability' guideline in practice. But this leaves a gap of things that are clearly notable, but lack good sources about them. In that case Wikipedia is stuck between not covering a notable subject (bad), or covering it in an article that isn't properly cited (also bad). http://www.kmjn.org/notes/wikipedia_notability_verifiability...

The reverse case, where a not-really-notable subject is covered because there are sources, I feel is less bad. If the external world is writing about a subject, then imo it's fine that Wikipedia summarizes what they have said about it. At the very least, many such things (like celebrity missing-child cases and vaporware tech companies and whatnot) are meta-notable for the media attention.
That's a pretty sad but true realization.
My experience as a Wikipedian suggests that Wikipedia's administrators need to be much more alert than they have been to the possibility that the Wikipedians motivated by money (or by ideological bias) will stay with the project and persist in making edits contrary to Wikipedia policy. They edit more articles, and edit in greater numbers, than most admins guess or notice. And the point-of-view-pushing editors often inject so much wikidrama into discussions about how to improve articles that they drive away the participation of conscientious editors who know reliable sources about the article topics.

A current example is the article on Rupert Sheldrake,[1] which has recently been subjected to vigorous edit-warring, perhaps as part of a publicity campaign by followers of Sheldrake. (I just saw a new book by Sheldrake at a library yesterday, and perhaps that book's publication set the timing for the editing push.) But there are examples like this all over Wikipedia, and, again, I think most casual users of Wikipedia massively underestimate the percentage of articles that are edited mostly in the interest of pushing a point of view for commercial or ideological reasons.

The article kindly submitted here says, "Anyone can edit Wikipedia, but only a carefully vetted few are promoted to admin status on the site." And that is laughable. Describing the current group of Wikipedia as "a carefully vetted few" does violence to the English language. Nothing has ever been careful about the process for checking the background of administrator candidates or choosing which candidates become administrators. There are some very, very, very good administrators on Wikipedia (just as there are many very helpful everyday volunteer editors), but there are other administrators who are power trips to maintain conduct contrary to Wikipedia policies for building a good, free online encyclopedia. The Vice article submitted here does, at least, link to an Atlantic article[2] reporting that Wikipedia's rate of bringing new administrators on board is slowing. At least some of the administrators have been caught taking payoffs for editing articles to publicize the persons making the payoffs, so it will take more than just the current administrators being more alert to fix this problem on Wikipedia.

>Today PNG 24 is the only way to achieve transparency with a 24 bits palette, resulting in unnecessary huge files.

That's not necessarily true. If you only have completely-transparent and completely-opaque pixels color type 2 will work, and if your total unique colors (RGBA) number less than 256 you can still do plaetted.
one evidence was from a contributor who quit.Being volunteers not everyone likes to be only cleaning someone's mess.Besides scale of Wikipedia might grow quite big for the 10,000 odd admins to manage and who know how seepage might happen!Also Wiki-PR was one, who knows how many more are left!
I don't believe that this is a major problem for the technology. I can imagine that the level of flux (amount of electrons coming through the device and being accelerated) is rather low at the moment however.
The plane that dropped this bomb would be a larger weapon given a plane can be used as a weapon. Along the same lines aircraft carriers would be the largest weapons I could think of. Though many countries have dabbled into weather modification, then there are gas and other chemical weapons.
So is it largest based upon volume or size or weight or it being 100% dedicated weapon?
Another historical example beyond those large train driven guns the germans made would be during World War One in which it was common to dig a large tunnel under the enemy fortifications and place tons and tons of explosives under the enemy in which you would eventualy set of blowing up the enemy - http://en.wikipedia.org/wiki/Battle_of_Messines_(1917) being a very interesting read in itself involving hundreds of tonnes of explosives. Though like landmines not all got set off and case here http://rense.com/general47/50000lbWW1bomb.htm about a 50,000 lbs bomb (22.6796 metric ton), which is still lighter than this Tsar Bomba.
Though more background upon such explosive type bombs can be gleamed here http://en.wikipedia.org/wiki/Tunnelling_companies_of_the_Roy... and mention is made of a of a far heavier:

""As preparation for the attack, six mines were detonated on 27 March 1916. The largest of these was at St Eloi, dug by the 1st Canadian Tunnelling Company, consisting of 95,600 pounds (43,400 kg) of explosive. This allowed the capture of St Eloi by the British 41st Division.[20]
This choice reduced the total explosive to 450 tonnes. The evening before the attack, General Plumer remarked to his staff, "Gentlemen, we may not make history tomorrow, but we shall certainly change the geography." ""

So personaly I'd not say it was the largest or is the largest weapon ever made. But certainly the most scariest.
Redirect URL when you give access to Facebook is different for other email providers. Hotmail (that is, Outlook) is the only one that worked as far as I know - I have tested Gmail and yahoo, but neither of them were exploitable (there is also chance I missed something, so it is worth checking again).
It's not that he doesn't believe this happens, but rather that the presence of a story about it in NYT where chick-fil-a is mentioned directly in the first paragraph is not an accidental matter. Chick-fil-a being the main restaurant talked about in a feel good article like this is great PR for them, discounting the possibility of it having been arranged deliberately just because the op was overly cynical is a bit petulant. PR is almost never about making things up, but rather the timing and the tone and the things mentioned in the periphery of the story. PR firms know that a straight-up story on how chick-fil-a is great is not likely to do much for them with world-weary americans, but a feel good story about people helping each other (which may very well have happened) with chick-fil-a strategically placed just in the background is great.

I worked for 10gen (now MongoDB) for over 2 years (I left in December).

Never once while I was there did they publish a benchmark: There was a [publicly] stated company policy to not publish or comment on benchmarks.

If you have evidence otherwise (i.e. benchmarks published by the folks working on MongoDB) fine, but I take this as a deliberately inflammatory (and false) statement.

EDIT: The global write lock was removed ~last August; there is now a database level lock. Future releases will likely make that more fine grained. Additionally, the drivers no longer do "unsafe" writes, but check w/ server.. as of the same release.

It seems to work in Safari as well. I sort of understand the dword format, but why would this be useful, or a standard?
Knowing whether a hum is 60Hz or not tells you whether it's a ground loop or some other problem. For crosstalk a lot of mixers have a 1khz sine tone generator. It's useful to be able to verify that you're dealing with a particular frequency. You are not always able to rely on your ears to the extent that you'd like when you're in the field, since the environment where a PA is being set up can be noisy as well.

This device has a few other tricks up its sleeve as well as a basic 'scope; it also does FFT, phase metering, and operates as a voltmeter. I'm not suggesting it's the ultimate device of its kind, just pointing out that there is a class of people for whom having this functionality in a highly portable package would in fact be handy.

Oh, and the protocol sniffer means you can test MIDI output from a synth or sequencer.
I like this too. There's very little to criticize, since it basically tells it exactly like it is without too much embellishment, and makes intelligent, honest conclusions.
