The original article had the link to the code so don't even try to imply that I was hiding jack squat. He hasn't nailed shit, it's the same test epoll proponents have used for years. It's not a "localhost" test, it's a test that makes a bunch of file descriptors and then compares the poll vs. epoll performance as active vs. total changes.

But hey, you can live in your own little fantasy world where you think you've won some kind of battle of the HN because you listened to some epoll fanatic weirdo and cheered him on.

I wonder why people want MS windows to be Open Source. Actually, it's very flexible and customizable from top to bottom. I don't have an idea about Windows Mobile, but the fact that HTC has integrated their HTC sens in it, means that it has a great degree of flexibility.

I wonder why do you want Windows to be Open Source when you can pretty much customize anything.
"Your hypothesis is that web servers have the majority of their fds active most of the time,"

Aha! Totally wrong. My hypothesis has not been that at all. You totally didn't even understand the hypothesis, and I stated it very clearly. My hypothesis has always been:

epoll is faster than poll when the active/total FD ratio is < 0.6, but poll is faster than epoll when the active/total ratio is > 0.6.

Nowhere in there do I say that all web servers have the majority of their FDs active. NOWHERE. I say some might, I say who knows, I say we need to go measure, but nowhere do I say anything like what you say.

Currently, VimJolts is in under construction...

It may be great, but it's hard to say. There's not yet a lot of there on the website. (Does it support uninstalling? How are installed items organized? Do items have to come from Github or also Vim.org?)

Edit: The README on Github is a bit more informative (yes, uninstall is supported): http://github.com/vimjolts/vimjolts

As an alternative, perhaps Pathogen (not really an installer, more like a style for managing Vimscripts) or Vimana (a full installer).

Let me add the hidden cost of mining. From the Areva wikipedia page:

---
Areva has been criticised both in Niger and the west for a neocolonial relationship with the former French colony, having obtained monopoly rights to mine uranium for nearly forty years, while Niger remains (as of 2006) the least developed country in the world.[16] There has been specualtion that Areva was the primary vehicle (and motivation) for French government involvement in the Nigerien government's poor history of democracy and human rights since the late 1960s.
Areva argues that it is a good steward of the environment and a partner in development with the Nigerien people. The company stresses that most workers it directly employs in Niger are locals, and that the revenue generated by these mines is the single largest foreign exchange source for Niger.[17] When the population of Niger was exposed to a serious famine in 2005, Areva donated 130,000 euros in June 2005 to the food crisis coordination group of Niger, and 120,000 euros in July in the form of two planes loaded with food and organized by Bernard Kouchner's Réussir NGO. Nigerien critics point out that this aid amounted to 0.05% of Areva's annual profits of 428 million euros.[18].
In January 2008, a Swiss human rights group awarded Areva's Niger operations their "2008 Public Eye Global Award" for the "worst company in the world", citing charges of radioactive pollution, poor working conditions, and the deaths of a number of workers.[19] The Tuareg based rebel group fighting in the Arlit area has echoed these charges.

I've played with riak a bit (just in development, no deployment yet) and I have to say it's wonderful.

The Riak Fast Track tutorial (https://wiki.basho.com/display/RIAK/The+Riak+Fast+Track) is phenomenal. I wish more tools had this.

MapReduce interface is nice, links are great, status info is mighty, the distributed setup you get out of the box is fantastic, etc. etc.

Folks who need any kind of key/value store should definitely check it out.
That thing is really creepy if you do a git-rebase with a lot of commits.
Exactly, there's no concept of confounding at all. You use "real world tests" (whatever the hell that is) when you have an actual specific setup to test. You use a small model experiment like this to test one specific thing like poll vs. epoll.
That's not how computers work.
I disagree. I prefer honest people and at times honesty is negative. Some people are mean and horrific. How could a Jew describe Hitler positively? Tell the truth, just because it happens to be negative is not a bad thing and does not make you a bad person or negative minded with low self-esteem, etc.

I don't think mobile search/advertising threatens web search - it's a new industry. People aren't going to search less on their PC because they have a phone that allows them to search. Google moved into mobile because they wanted that additional opportunity, not because their old one was shrinking.

Likewise with Facebook - though the threat there is that more people sitting on Facebook = less people looking at Google ads.

I think there's a difference between a threat to existing dominance and a threat to future opportunity.

Ask HN: What would you use to query large (2-25TB) of read-only data?
The data set is written once a month in bulk, and read many times by different users. The last month of data (~2TB) is the hotspot. A year's worth is ~25TB.

The attributes of one record are as follows:

* 1-4 character string
* float
* float
* integer
* integer
* integer
* integer
* integer
* 1 character

For each 1-4 character string, there are many records -- sometimes several per second. As an example, in the span of a month, one of these strings can be associated with 18 million records. There are about 10,000 unique 1-4 character strings, but not all as active as the previous example. The data is queried by two attributes: 1-4 character string and timestamp.

Potential solutions I've come up with (feel free to debate any of these):

* Put everything (or just the hotspot) in a MyISAM compressed database.
* Put everything (or just the hotspot) in an InnoDB database with a proper clustered index.
* Put everything (or just the hotspot) into CouchDB with proper views.
* Put everything (or just the hotspot) into MongoDB with proper indexes.
* Put everything (or just the hotspot) into Redis ZSETs with timestamp as SCORE and distribute across nodes.
* Load all of the data into a long-running Hadoop job.

Feel free to ask any questions too.
Another common gripe about California that I'll echo here: there's no weather! It may sound masochistic but I miss the seasons, the snow, wearing a scarf, sheltering inside with a cold nose and hands with something warm. The passing of the seasons gives life a constant pulse and direction. The eternal summers of CA get to be disorienting after a while.
You know what I find troubling about your behavior on this thread? It's just so weirdly manipulative. I gotta think you have like 40% stock invested in Epoll, Inc. or something. You make wild claims about what I'm saying that aren't true, you imply that I know nothing of real world performance when I've written some pretty bad ass real world software. You reply to every single thread with a constant stream of FUD and nitpicking everything you can then blowing it out of proportion.

I mean, are you sure you didn't used to work for Microsoft and then got hired by Linus to work your FUD spreading magic?

I agree that breastfeeding should be encouraged, particularly in 3rd world countries.

However, the mantra of "breastfeeding has been scientifically proven to have benefits" may be less solid than you think.

There is a strong correlation between mothers who choose to breastfeed and lower incidence of many adverse conditions. However, does this imply causality?

"Conclusions: A history of breastfeeding is associated with a reduced risk of many diseases in infants and mothers from developed countries. Because almost all the data in this review were gathered from observational studies, one should not infer causality based on these findings. Also, there is a wide range of quality of the body of evidence across different health outcomes."

Full disclosure: I was breast-fed and am perfect in every conceivable way.

"The self-righteousness that exists is part of an ongoing effort to turn back 50 years or so of misinformation that existed in North America..."

Isn't this exactly the point? Nearly everything we've ever known about nutrition has at some point been 'proven' to be completely, 100% wrong. Maybe we shouldn't be so judgmental of people who make different choices?

Granted, they're not completely successful at this but I think a lot of that has to do with our immaturity and privileged upbringing as much as it has to do with boring subjectss

That is mostly caused by the school systems. Our parents go to their job, and we go to schools.

We are forced into an artificial society of children, and with teachers as authorities. So, we learn what other children like, missing altogether the wisdom and experience(if there are any) of the adults.

So children become very shallow in their taste and what they think is cool.

>I don't think mobile search/advertising threatens web search - it's a new industry

I imagine someone in the buggy whip industry said that when cars started to hit the road. A more adept business mind would have probably try to adapt their business for the obvious future.

Mobile devices are getting more powerful and more usable. Google is a hundred-plus-billion dollar company built around search. The landscape of how people search is changing. Of course they need to pay very close attention to it, not for today but for tomorrow. Voice search on mobile devices is brilliant, as an aside.

>I think there's a difference between a threat to existing dominance and a threat to future opportunity.

Indeed, when you're a small company that's the general thought process. Google is a very large, very successful company. They don't want to be AOL or MySpace or Excite@Home. They want to continue to be successful by adapting to the world, and ensuring that the world adapts with them. Their Android initiative has no hope of ever making them any more than rounding figures on their balance sheet, but it does ensure that they remain engaged in search and mobile advertising.

It's interesting that you mentioned Microsoft because almost everything Microsoft does can be tracked back to concern about Windows and/or Office. Microsoft got into gaming not because they saw it as a lucrative opportunity (they've been pissing away billions on it), but because gaming and convergence represented a beachhead that could upset their domination of the home. It goes on and on and on.

The thing about Google is that it is like a hyperactive child who can't concentrate. NOTHING ever gets FINISHED.

1) Why can't I delete ALL spam in GMail at once?
2) Why do the numbers for my Bookshelves in Google Books disappear?
3) Why bother to OCR tons of books if you have no intention of cleaning up all the errors?

Those are just three that hit me personally.

But it makes me wonder what a mess the long-delayed and ever-upcoming Google Editions will be like -- which independent bookstores all think will save them from being wiped out by eBooks.
I appreciate the work you're doing. I'm not sure I've worked on a system that would really benefit from Mongrel2, but I think it's a pretty interesting concept, and there's always a chance I work on something more interesting in the future.

While intriguing to think about, this teleological viewpoint which she repeats a few times is a little silly. There isn't really a shadowy cabal of plutocrats secreted away in a subterranean headquarters inside of a volcano, planning all of this.

It's likely instead a series of unplanned, undirected side-effects from other things. Standardization could side-effect of trying to mass-produce education, which is a side effect of the increasing size and complexity of society. Educational institutions last for generations and stick to what they know because they don't know what else to do. It's very difficult to get feedback or to infer causal relationships or have anything resembling an experimental control over a 20 year education process and literally a lifetime. No one is directing all of this from a secret mountain lair while cackling malevolently and stroking a trained leopard.
The old logo gets the job done, the new one tries too hard to be trendy and fails (it also looks very generic). Sometimes the literal approach is a good idea, even if the production value isn’t there.

You are correct, it does not resonate with me. But even worse, it makes me think you (the rhetorical you, of course, not YOU personally) are trying to invalidate the anger/sadness/grief that I feel. People go through some incredibly shitty times, and for you to walk into that and say "hey, look for the bright side!" is not helpful.

> Connecting to purpose of some kind can help people find strength.

Sure, it can, but I doubt they need you to point it out. The reason it's a cliche is because everybody's heard it before.

So, OK, there's a chance you might say it to someone and it genuinely comforts them. But there's also a pretty good chance you're just going to alienate them. Up to you.
I'm also not convinced the choices are always for "convenience".

> Ultimately though, I'd rather have the Linux kernel just fix epoll so it's always faster than poll.

Unless they break poll, that's very unlikely. The implementation of poll is much simpler and should be faster per fd. What could happen is that epoll gets some improvement that moves up the .6 boundary but I seriously doubt epoll could ever be faster than poll with 100% active fds - and I never encountered that kind of usage.

As with any optimization, we should be concerned with end result: how much slower does using epoll really makes the system. I am on the skeptical side here.
predictive feedback isn't all that useful. if someone is trying to predict success or failure before a product or feature is released, you shouldn't weigh it so heavily. you can find plenty of people who, in past writings, dismissed things like the internet or mp3 players as trivial or fad-ish.

responsive feedback is useful. if someone who is using your product has something to say about it, pay attention. you don't necessarily need to act upon a single person's feedback, but it is still worth making notes upon for future reference.
I feel that learning to solve for x, learning the capitals, writing a formal letter, etc. can all be handled better than "repetitive, boring, tedious tasks." Why am I solving for x? How would knowing the capital of Nebraska ever help me? When would I write a formal letter? These are questions school fails to answer and thus fails the students.

For example, teachers could give projects out that involve a closed-system and get the students to work through the problem until everyone understands. I have spent weeks being taught a single subject because the teaching pattern involved putting a math problem on the board, wiping it off, repeat until the bell rings...

Another example would be finding a business that they deal with regularly and writing a formal letter expressing their concern/surprise at the services the business provides. In school, instead, I was given the task of copying word-for-word formal letters out of a book for the purpose of replicating something identically.

The problem is that we are graded and passed based on memorization, duplication, and busywork. It's not that we accomplished anything in particular - we just learned a little stuff without much purpose (most of which will be forgotten within a year or two).

The first thing is to actually talk to your potential users. I don't think bloggers are going to be of much help in this phase. You are looking for feedback and want to talk with real users.

I would not spend time creating a screen cast yet. If you have a few screen shots or can just describe the product to them directly. Ideally you would want 10 passionate customers. If you only have 1 or 2, their feedback might drive you in the wrong direction.

As technical people, we would love to just email a few people or post a comment on a blog. But to get great users, you have to engage them. The best way is to go out and physically talk with them. Since your market is restaurant/cafe/bars, you can do it all locally which is great because you can read their body language, watch them use it, etc.
