>6. Their measurement method is very inaccurate. Asking people where they found out about you has been proven to be very very inaccurate. Instead, give them a coupon and track based on that.

I've found more often than not people simply take advantage of the offer of the coupon, and rather than "new fans" of your franchise, you simply get one-timers. They're bargain shoppers, not potential repeat customers. This is the same problem that plagued many Groupon clients. So while it might offer you a hard and fast showing of how many people are willing to try your place with a coupon, it doesn't prove a) your ad has reach on its own merit, or b) that you're targeting the right group with your ad.
While some of the author's criticisms are valid, some of them are completely wrong:

What? db.collection.update does exactly this. See: http://www.mongodb.org/display/DOCS/Updating#Updating-update...

MongoDB fit a nice niche for a read heavy mid-scalability db solution. Every DB has it's niche. Trying to use it outside of what it's good for is going to get you burned. If people just did their research before blindly committing to a platform, we'd see a lot less posts like this.

Yes, southern europe generally supports and even uses credit cards. Holland has banned swipe all together. You need an authentification chip and a pin.

In our defense: we had to, because the skimming by eastern european criminal organisations was getting out of hand. There were incidents were they completely replaced cash machienes with identically looking clones.

So, in holland, get money at a tourist bank, the airport or your hotel. Beyond those places, you cant swipe anywhere.

There is no single way to control the memory usage using system tools except maintaining mongod instances on dedicated virtual machines without running further services. There are numerous complaints from people about this stupid architectural decision from various side and 10gen is doing nothing to change this brain-dead memory model.

Can someone explain to me why this is actually a big issue? Except for really tiny apps, I imagine that having dedicated VMs for your MongoDB actually would be perfectly fine? Probably even preferred?

Most of these sites will have very detailed monitoring of performance/revenue generated by their ads. In all likelihood they've A/B tested ad impressions, clicks, conversions, and revenue generated by a single-page article versus the same on a paginated article, and discovered that (intuitively) spreading the content out over multiple pages with more opportunities to display ads gives better results. Maybe it's only marginally better, but in the world of online advertising even the tiniest improvement in conversions can mean huge changes in revenue when you throw enough users at it. The fact that some users may be annoyed by or made "immune" to ads is moot. They'll go where the money is.
The trend is this: any loved technology that's been around a little while (Rails, Node, Mongo, etc) makes for dramatic farewells on hackernews. It's not unlike supermarket tabloids.

I've tried and failed to set up IPv6 on my MBP a few times now. HE seems to provide free tunneling, but I can't figure out if it's compatible with my AT&T U-Verse RG.

Is there a way to enable IPv6 tunneling on OS X in a way that doesn't require firewall configuration?
I was wondering if he meant copy fields from one column to another, or to modify a value in a document based on the value in another field. I don't think that's possible in Mongo without writing server-side JS or doing it in your client.

Agree with your general point, though - this seems like they have a product/tech mismatch. Though I'd argue that this isn't a niche - read heavy, mid-scalability is a lot of the web.
It takes guts to take a leap like this. Good luck, I hope you succeed.

It doesn't strike me as ridiculous to make a server-side Javascript framework. I'm not interested in Node because from code examples I've seen, its programming model seems to make doing even simple things quite complex. I really like Javascript, though.
I was going to use Node.js for a site I was building, but then I stepped back and realised going with Node.js (and MongoDB) meant I had absolutely no idea what I was doing.

I stepped back and used Python with Flask and SQLite as I had done before. There was nothing wrong with what I was familiar with. (An added bonus was I could actually reuse code from an older project using a similar architecture)

The reason I don't want to write much in node.js is simply I don't like callbacks. It's an inversion of control, and not a necessary one. One can easily invert control back to direct style by using futures/promises. There are even node.js extensions that do various conversions back to direct style, but since the language doesn't endorse any particular one you can't use them across a whole app (unless you write everything yourself).

I do test for caching (though I must admit I write first, test later); I'll write that up in a later post. Similarly, I'll put up some comparisons to show the performance difference those changes have made :)

I think everyone should be caching as the speed of your page loads is fast becoming an even more important factor in people using/enjoying your site. Everyone (including myself) is getting more impatient in regards to page load speed, and every little helps. Also, you never know when you'll hit the frontpage on HN!
Startups Paradise - where startups go to die
This article is spot on. We'd all like to have magical properties like speed and scale instantly conferred on our code merely by using the right tool. The fact of the matter is that both of those properties require consistent correct decisions at the application level to be achieved.

Scale, for that matter has been totally conflated with speed by many in the Node.js. A single-core reactor is not inherently scale-out. You can, of course, build a scale out app on node.js, but there's nothing about using node (or any other tool) that magically makes your app scaleable.
We (everyone reading this) will be dead before that happens. Not because the technology won't be there but because making auto-driving cars mandatory won't fly culturally/politically, certainly not in the US.

We'll have optional self-driving Google-car style cars soonish (maybe 10-15 years out when you factor in all the regulation hurdles), but they won't be mandatory for a very long time, if ever, and if even a small percentage of people opt out of the automatic driving system we still need the current control systems and road rules in place.

FWIW: I loved Blizzard in the past. I didn't buy into SC recently. I didn't like the decisions taken, stripping one good game into three, adding weird rules to the TOS that just cry out "I want to milk fans" (think: LAN games, tournaments).

For WoW they were stoned for a while and considered a real name policy in their battle.net system..

Now Diablo comes along. Blizzard isn't special for me anymore and always online games get -100 points by default. For now I guess I'll pass (with SC I don't regret it one bit) and go back to Warcraft III again.

Blizzard of today is to me what the 'new' Star Wars episodes were: Bringing joy to lots of people, but disappointing for me.

I disagree. The trend is this: any hype has an equal and opposite anti-hype. 10gen have spent (probably) millions of dollars and countless hours representing MongoDB and singing its praises in various media (conferences, user groups, Web, etc.). If you do so, you need to expect equally fierce reactions when people realise your claims are unsubstantiated (or, at the very least, not as universal and problem-free as you originally portrayed).

Massive DDoS attack keeps The Pirate Bay offline for over a day
On Google most hits would be from people searching for "pizza delivery" or something similar. Clicks on Google's ads are driven by intent, while clicks on Facebook's ads are driven by impulse.

Facebook ads can work, but I don't think they work well for local businesses, but rather for big brands that want to build an image, more akin to TV commercials.
And on June 7th, everyone and their dog will still be using IPv4.
This is a myopic article. I challenge any marketing channel to drive instant real world sales for a brick and mortar retail store. It just doesn't happen like the article expects with its naive assumptions.

It is too early to measure the success of the ads in a real world scenario. These pizza ads are very much about exposure (and not BUY NOW) but the article presumes that the only metric of success is people running out the door, getting in their car and buying pizza immediately after seeing the ad. This behavior isn't reflected in other media, such as TV, magazine ads, billboards, PR, etc, so why hold Facebook to a higher mystical immediate marketing standard? Online ads can indeed drive immediate sales but that is for online businesses where there is buying intent, and this pizza store clearly isn't in that category.

Another aspect overlooked is that unlike a google ad or magazine ad where you pay per exposure/view/instance, these Facebook ads serve a lead acquisition strategy that can be used multiple times. Pay once to acquire the customer, then market as much as you like for free. Once you have the customer as a "fan" you can market to them every week or even every day making the original investment much more valuable. Marketing is about repetition and exposure so it may take X Facebook posts before the consumer receives sufficient exposure.
I like the idea of rewarding effort, too, but US courts have determined that the amount of work exerted does not matter for the purposes of copyright.
Pretty much any sane architecture has machines dedicated to handling the data store (MySQL, Mongo or whatever). If you are scaling up from a single machine, this is the first split you make.
Would love to hear about it and how it has changed your life.
The biggest problem with mongoDB IMO is that BSON dictionaries are ordered. Let that sink in for a sec: the hash data structure must be ordered....
The solution most drivers run with is to just alphabetically order each dictionary.... a ineffcientcy I'm not really happy with.

I think in defining a range, the toIndex means up-to-but-not-including the element at that index. Thus, to include the full array, you'd use the range fromIndex=0, toIndex=length (one past the last one, since the index of the last element is length-1). With this notation, you can then make ranges of any width, from 0 up to length. If instead you included the element at that index, you couldn't have 0-width ranges (unless you allowed toIndex to equal one less than fromIndex).

I don't know whether 0-width ranges are directly useful for the Timsort algorithm; or whether it's just a convenient notation that happens to have that ability as an unused side-effect.
I recall trying out cache-money a while back. I haven't tried out any of the current equivalents, but I may have to give them a go just to see what they can do.
I think this presents a flawed logic:

"It puts the method before the problem. Before you go rushing out to learn to code, figure out what your problem actually is. [...] Does coding solve that problem? Are you sure?"

Did we all learn to code, or program, as a reaction to having an idea that required learning to code or program? Or did some of us learn to code or program out of curiosity, or because we just wanted to, or as a hobby?

The quoted point discredits the latter in favour of the former (as well as applying all manner of extra requirements I decided to trim out).

The article as a whole doesn't respect the fact that people have extra-curricular activities, and hobbies. And side-projects. Should we all discard those things that aren't totally relevant to our full time job?

By "jab" do you mean derogatory remark? Does that not depend on the poster's perception of Reddit? If one considers them equal but different, then the remark is merely one of contrast.

Granted...

> There are no "community norms" for reddit

From what I've observed, there most definitely are. Their forms of humor are often upvoted across subreddits (e.g., inside jokes, meme's, animated gif's in lieu of discourse).

This is how I interpret the reddit "jab" comparison: go there for funny, come here for info; neither is better than the other.

If you personally feel HN is superior to reddit, than I can see why you'd consider it a jab.

Agreed. I found the mapreduce criticisms to be a little off:

> Now instead of fixing a bad implementation or fixing the underlaying architectural issues, MongoDB is moving to Hadoop.

I don't think that's accurate. They have a new "aggregation framework" coming that is meant to replace mapreduce. It could be a wrapper around hadoop, but I couldn't find anything documented about that. I completely agree that a blocking mapreduce is annoying, however, does any framework have a non-blocking mapreduce? I haven't tried many mapreduce implementations out, so this is a genuine question.

Advertising isn't about name recognition. It is about getting more people to buy more of your stuff and name recognition may or may not lead to more people buying more of your stuff. If you can't directly tie it to more people buying more stuff than you are selling faith in the power of name recognition. No business is likely to long base purchasing decisions upon faith.
Sure, and you can cure a rash on your arm by cutting the arm off.

Users can also be investors. How many users does Facebook have, who will want to own a piece of it? How many of them are going to worry about valuation?

I think Facebook is going to have good run. I wouldn't be surprised if Facebook goes up to 400 billion. Facebook even has the possibility of making investing in internet companies at ridiculous valuations 'cool'. Wall street must be salivating.

So shooting at burglar or somebody attacking you without a gun will cause you major troubles if the attacker should die.

IANAL, and it varies by jurisdiction, but I believe the general standard for using deadly force is ..

'Not allowed to use deadly force against any person except as necessary in self-defense or the defense of another when they have reason to believe they or another are in danger of death or grievous bodily harm'

Paraphrasing from memory.

In other words, I can employ deadly force against an attacker if I believe he could kill me. Doesn't matter if he's armed with a club, a knife, or a bazooka.

I can't shoot a guy if he's running away.

This seems prudent, but that (he smiled) might be a cultural thing.

Where I grew up they used to say 'God made man, Sam Colt made them equal' and I guess I still believe it.
