The author seems to miss the point. The iPhone has had a massive impact on gaming, like it or not. The iPad will too. This is why the new Nintendo and Sony devices may be DOA.

I do think that giving Steve Jobs credit as a person is wrong, though. He didn't seem to care much for games. And according to the book, he was against the App Store originally.
Some research suggests that even knowing that something is a placebo doesn't stop it from "working".

With BrainGym you need to realise (it's pretty obvious) that it's nonsense, but maybe just taking a short break every now and again and doing some "exercises" will be useful, for some reason not connected to all the nonsense that braingym comes out with.
What volume of pages are we talking about?

At below-mass-scales, I would encourage you to keep the page content roughly similar to what it is, mark expired pages as expired, and maybe put a modal window with "This ad is expired. See related ads or post your own ad." or something on top of the old content, with an option for people to close that and see the archived content.

At mass scales (more than "thousands" of pages), I'd suggest either a) doing the above but also no-indexing those pages or b) 301 them to the category page. The rationale for this is that you don't want to get hit by Panda for having lots and lots of not-so-much-value pages.

Except that wasn't the original point at all. It started with Jd saying:

"If you want to go to the moon you need a f'ing spaceship and not emacs and an open source notebook. Spaceships are big. They take a lot of people to run, and they have to be smart people. One mistake and you are smithereens at Cape Canaveral."

Followed by sedachv saying some guys who are trying to launch humans on suborbital flights would disagree.

Nothing you've said explains what suborbital flights have to do with going to the moon. On the contrary, you seem to be admitting they have nothing to do with going to the moon, so I still have absolutely no idea what sedachv's point was.

I've also seen a lot of SQL Server developers write large stored procedures that manage to easily deadlock. It's been years since I dealt with it...had something to do with lock escalation, from a read lock to an update lock to an insert lock.

Exactly. The hardcore PC/console gaming crowd is in for an unwelcome wake up call: the future of gaming is mobile. In fact, it isn't even limited to the future, it's already happening.

I think it's fair to say that devices like the iPhone and iPad will be seen as the originators of this revolution. So maybe that group of avid enthusiasts is a little more insightful than the author is willing to give them credit for.

This fails for the most important reason: backups.

Automating backups is not enough, a test restore and compare should be performed or the whole job fails.

An actual restore can fail for a variety of reasons, especially if using almost-but-not-quite-obsolete tape media.

(Think of it as continuous integration for data.)

As an Aussie living in the US and somewhat out of touch with what's going on back home, I'm fascinated and confused by this. Are you arguing FOR or AGAINST the idea that there's a significant asset bubble in Australia?

We were recently looking at relocating to Sydney and were blown away by how prices (including rents) had increased since I last lived there (in 2002).

The interesting thing to me is that rents in Australia seem to have skyrocketed while prices have not (they're high, but rents are higher). In the US the housing bubble was characterized by prices increasing far faster than rents (which led to an illusory improvement in standard of living as people borrowed against "equity" and spent the difference). It looks to me as though Australian rents have risen faster than prices, which presumably has the reverse effect.

Essential for a few reasons:

Events - a lot of people post events on Facebook and trust that all of their friends will see it.

Photos - a lot of people only share photos through Facebook. If you want to see or download photos someone has taken at an event you were at your probably need to use Facebook.

Email - most younger people do not use email (unless they have to for school/business. Instead they use Facebook messages.

I won't bother addressing you last comment. Maybe your experience of high-scool was different than mine was, which consisted of a lot more that 'silly high-school gossip'.
I agree: mobile gaming is the wave of the future. But if you want to know who has affected gaming most since its inception, the answer's pretty much got to be Shigeru Miyamoto.

The problem with this poll is that it works just like "greatest movies of all time" polls. People have the attention span of mayflies.

I'm surprised nobody has mentioned the obvious big drawback, which is that you still need to take care of backups.

A real game changer would be if a low power server came out with an integrated point and click solution to have the data automatically backed up!
First, the more I have looked, the more I have found that non-relational database systems are remarkably common and have been for a long time.

The relational model is ideal in many circumstances. However, it breaks down in semi-structured content, content where---parentheses for grouping---(hierarchical structure is important, data is seldom written and frequently read, and where read performance navigating the hierarchy is most important) and so forth.

So I'd generally agree, but not every problem is in fact a nail.
I don't think I would call O(n) of the amount of allocated data 'pathological'. Nor would I agree that completely incremental collectors being rare proves anything about what is possible. I would say that it's simply developers preferring a runtime that's a small linear multiple faster but has occasional pauses.
Nice, it's the embodiment of every negative stereotype of CS programs.

Has anyone thought to compile a list of schools outside the MIT/CalTech/CMU/... level that still teach something resembling computer science? Or are they all just bad IDE trade schools now?
My guess upon seeing list(a) for the first time would have been that it returns [a], which is worse than not knowing what it does.

Possibly this is because I've known lisp longer than python.
Even though this implementation is short, don't think it is efficient.

Matching regular expressions can be done in linear time.

This presented algorithm takes exponential time.
It's one thing for two transactions to deadlock against eachother. It takes special talent to allow a transaction to deadlock against itself, which InnoDB apparently allows.

I have NEVER had issues with PostgreSQL transactions deadlocking against themselves, even with monstrous stored procedures.
Living in Germany I have the same impression. This myth seems to be restricted to North America or English speaking countries.
2. Financial instability had minimal to zero systemic impact in advanced countries because banks were only permitted to engage in funding and financing directly related to the real economy.

Um, the dotcom bubble happened under Glass-Steagall. So did 1987, the 1997 Asian financial crisis, and the 73-74 crash.

3. In addition, a side effect due to the partitioning and lack of artificial wealth interconnectedness, TBTF was not possible.

No. The Savings&Loan bailout and LTCM bailout both occurred under the Glass-Steagall regime.

4. All manner of speculators were able to exist even then, but they knew they only had one chance with the capital they had since completely different types of financial activity were not allowed to co-mingle under the same organisation or group.

You have no idea what you are talking about. The decline of product-specific trading desks was caused by the onset of stat-arb and had nothing to do with Glass-Steagall.

40 years later, here we are - in real (inflation-adjusted) economic terms per capita for median person effectively back to square zero...

This is a statistical artifact. The median person who's parents were in the united states in 1968 has income (adjusted for chained CPI, which is not the same as inflation) 29% higher than their parents. Immigrants lower the average/median.

I never really "learned" lisp (I read a library book about it as a teenager but I didn't have access to a computer that ran it.)

But I did learn Haskell later, and I think that made me worse at the job (C++) I was doing at the time, because it gave me the habit of trying to write C++ in a functional style and made me more frustrated with C++'s type system.

The same should be said for ODMs as well. A document might be a little more straightforward to map to an object but there is still plenty of miss-match.
It's all a tradeoff. I'm ok with giving up the freedom to install any random software off the web on my phone, if in exchange I get access to hundreds of thousands of apps that just work, are cheap, and do pretty much everything under the sun without screwing up my phone.

Not having to worry about being a sysadmin for my phone gives me more freedom to do the things I actually want to do. As the Linux world and its permanent state of "it'll be ok next year" have demonstrated, you can't have it all. Freedom to mess with the innards of your system, or freedom to forget you're using a "system" and just do stuff with it. Pick one.

Just reading about your transactional volume, it seems like at it's face MongoDB wouldn't be a good fit for this project. 30k per second is not anywhere MongoDB pretends to live, I think by their own admission. And Sharding in MongoDB, while being called a core feature, was bolted on after core development, probably intended to give Mongo some credibility with those who want it to be more scalable. IMHO if you need that kind of scalability, you're already straying from the Mongo Niche, 2.0.0 notwithstanding.

So agreeing with a point earlier, if you don't like a write lock implementation, and have concerns about scaling, and have a huge transactional volume, just really not something that fits well with MongoDB.

I've been using Mongo now (currently using 1.8) for three (is it almost three now?) years, 2 million hits/day, with a replicated set, and while I've needed maintenance, reindexing, and (gasp) restarts on occasion, never had any of the problems identified by the author of this post.

Bottom line, sounds to me like someone was in over someone's head from an architectural standpoint, made a bad choice of MongoDB, and then blamed 10gen for his own lack of foresight. So while I empathize with the struggle, I fault him for not knowing his options in advance, TESTING first, then betting the farm on a fairly new opensource codebase.

LOTS of other database solutions that would scale better. Analyzing lots and lots of transactional stateless data with MongoDB map-reduce? Well, just kinda like killing yourself by trying to sprint up from the bottom of the Grand Canyon. "You really tried to do that?"
If you can dial 911, don't just hang up, the response to that will vary from one place to another, even from one dispatcher to another. You need to find some way to make clear you're in trouble.
The artificial supply squeeze on industries benefits... what exactly, besides Goldman itself?

If aluminum becomes more scarce in the future (Goldman seems to be betting that it will be), then Goldman has done us all a favor by conserving it in the present.

If it is not more scarce in the future, then Goldman will lose money.
Falls flat on its face as an example of how not to design a website (doesn't display anything in Safara on an iPad).
Parse is very unsecure because you essentially give the user full read/write/delete access to all of its data as no logic is run server side but clientside. That means any scriptkiddy can change all data as it likes.

That has nothing to do with MongoDB, but with the cirtical design flaw of Parse to trust the client not to send fake data.
Uhh, I didn't realize that was a "thing" with Cassandra, is there a bug # to track for any issues specifically or are you saying that it has a history of reporting "Okey Dokey!" to a PUT when in reality it just exploded and died?

I've not messed with Cassandra in production so I haven't seen such a thing yet.
HWK Release 06/11/2011
I think the notion that the fundamental problem is that "smart" people don't want to be teachers is wrong. I think the real problem is that education simply, for lack of a better way to phrase it, has become more about careerism and a "hustle" than teaching anybody anything useful.Especially anything that's financially worth the costs involved. The "smart" teachers who don't like this eventually just throw in the towel and accept it, or are marginalized. The other "smart" ones who have no problem with this arrangement simply enjoy the ride and accept it as "life".

I'm mostly referring to middle to highschool (US) and (some) colleges, plus I am not including people who enjoyed the good fortune of an alternative education or being born to an educated parent that happened to be an engineer or something.

I think KA is an opportunity for people to congregate outside all of this chaos, hence slowly bypassing the "major players who have no incentive to change" and experiencing some kind of possible alternative. Hopefully it grows past the sterility of technology into new cultural norms that are beneficial. If not, it can't get any worse.. so who cares.
Ask HN: How do you use your home server? 
I've assembled atom/mini-itx based home server and looking for ideas how can I use it.
It's already used for:

- torrent server with transmission (also tried utorrent server but it crashed continuously)

- backup other computers with rsnapshot

- samba server

- different sites not ready for public so doesn't require ordinary hosting

Plan to use it for:

- install dlna server to stream content into lan

- calibre server for my ebook library and converting feed
for reading on kindle

- move my gitolite server there

- asterisk, still not sure do I need it

- monitoring of my sites

- install zoneminder and plug video camera for video monitoring

Any other ideas?
Awesome idea. Poorly executed design though and I see a chicken and egg problem. How do you plan on solving this?

I've had similar performance in my use case (big joins and very large tables) using PostgreSQL (in my case) and disabling sync() to disk, and tuning the buffers, as with the various NoSQL I tried.

It seems to me that NoSQL does not really bring speed. Just scalability and a different model. Hopefully most of them don't lose data at random. PG certainly doesn't, even with sync() off.

I have not tested the scalability of PG.
"Don't Use MySQL" still should be conventional wisdom.

Indeed it's the only database system I have ever used where a system with a single transaction running only multi-row inserts into a table can (and frequently does) deadlock against itself. Don't get me wrong, time was when it was easier to use than PostgreSQL but that time is long since passed.

One area I have continued to recommend MySQL has been in areas of content management but to be honest in many of these areas, NoSQL is actually a better fit.
Which devices will get Ice Cream Sandwich?
Ahh good catch, I forgot about Neo4j. I'd like to see some non-graph deployments on it and see how it performs. From what I've seen with social/networked data models it looks very compelling.

Yeah, the supply chain took a pretty decent hit with Western Digital (they make about a third of the market's HDs and are saying production will be 50% lower than usual on their end).

Supply / demand is pretty slanted and it will take probably take while for things to work themselves out:

HDD Demand: 180 mm units
HDD Supply: 130 mm units

That's the big downside to having these lean supply chains, a slight hit to one manufacturing site can have a big effect globally.

Aishwarya Rai to Deliver Baby on 11/11/11: Aishwarya Rai 
As everyone know that world's most beautiful actress Aishwarya Rai is going to be a mommy. This good news was revealed by Amitabh Bachchan, Aishwarya's father-in-law via Twitter. Not only the Bachchan family but the world is excited about the new born baby. Baby is gonna be special in its own ways. It was recently reported that Aishwarya Rai Bachchan will be going in for a C-section delivery on 11.11.11 and that a room has been booked at Seven Hills hospital at Marol, Andheri (E). Now it is the turn of her due date. Bookies were in an overdrive betting more than a hundred crores on the sex of Aishwarya's baby. Buzz is that as her due date nears, bookies are gearing up to receive bets on the exact date she will deliver on November (11-11-2011)
> There are two basic components in house prices: the cost of land and the cost of construction.

Those are the components of house cost, not price. Price is determined by supply and demand. Take two identical houses on the same street, the one in the superior school district will command a much higher price.
To bad prices did not actually rise 180% in a month or you could link to that article. As to why he shows a graph which demonstrates what he is saying is a lie... Vs showing 60-140 = 133% price jump which is still huge.

PS: Look for 1 month where the prices increased 180%.

Well, that's not really reasonable. Now you have different ticket prices for different movies (patrons would be outraged) and then you have inflated concession prices for all patrons (or only some?). The software that movie theatres use to run their POS terminals isn't that flexible.
