Am I the only one who is less convinced after reading this? 10k inserts in 5min on a laptop. That's enough for 95+% of stuff I work on. Seems like my time is better spent learning technology that has performance leap over esoteric tuning of SQL Servers. Leave that to people like the author. I'm sure there's plenty of them to handle the small % that need this level and no more.

"All children—clever or less so—were to be taught in the same classrooms, with lots of special teacher help available to make sure no child really would be left behind."

I imagine this would be very frustrating for a child who is considered "clever". By lumping everyone together in the same classroom, the kids who are ahead of the others could quickly grow bored and lose interest. I live in America, and I know that I was bored as hell until 6th grade, where classes started to be filtered based on abilities. While this article focuses on standardized test scores for all students, I would be interested to see data on "gifted" education in Finland using this one-size fits all approach.

I have a[n up to] 25 mbps line, Shaw is rolling out 50 mbps but upstream isn't really improving so big deal. Downstream is not my bottleneck for most things but online backups and such are painful. I'd blame the technology but DOCSIS 3 allows for more than that, and Telus has fibre in Canada with similarly castrated upstream bandwidth.

Why did the tablet PC so hot today?
Apple created the tablet PC market, android enriched the market. Tablet PC is the integration of a lot of portable digital products, and manufacturers too need to increase profits depend on new products, so why today tablet PC so hot. In general divided into three kinds, one is represented by high-end Apple, second-class brand; the last one is as shenzhen China tablet PC as the representative. The next is the detail of the reason.

freight cost is tricky to compare, but considering Trans-Siberian Railway is competing with the long-way sea route, and is mainly winning on speed and safety thanks to pirates. *

I think shipping via ship is going to be way cheaper than the to-be-built tunnel, unless, maybe if you are shipping from Siberia to Alaska?

*reference:http://en.wikipedia.org/wiki/Trans-Siberian_Railway#Developm...
Alaksa is really really big.

Rail lines aren't really all that wide.

Compute the fraction of Alaska and Siberia's land from which you'd be able to see or hear the trains going past and it's... quite small.
Right. In that case I really can't see much use for this tunnel.
Yes, but it looks like it's invite only right now?

I think its because paying for a tiered connection speed is set-and-forget. Paying with a monthly data cap effectively overlays an economic decision over each interaction you have with the internet. "Do I click this link? How much bandwidth will that use?" Even though I think most people probably would end up not thinking about it on a link-by-link basis, they do have to devote some mental power to monitoring how much of their data cap they've used, how much they have left in the current billing cycle (especially under billing regimes that charge way higher marginal costs when you exceed the initial cap - e.g. most US mobile phone voice minute plans).

It's just annoying. Even though it seems like tying the price of something to your use of that thing is the most efficient way to bill, it just sucks because then you have to think too much about every use: text messages, AOL hours, phone calls, until these things got so cheap that they weren't worth metering, all were in that category.

Personally, I suspect there's some behavioral economics ish at work here that is measurable, like...you know how some hotels and cruiseships have all-in prices? I bet people are actually willing to pay more for the same amount of consumption with the 'unlimited' plans because they enjoy not having to worry about it. This would also be pretty easy to test with cruiseship or all-inclusive resort data where they also sell other a la carte packages.

I have data cap plans on my phone and iPad, and I don't really mind them, but its only because I know that they are effectively unlimited: I never come close to using up the cap level of data. I don't watch Slingbox on my phone, etc.

I tell you what really burns me up though: the fact that even though I am paying per-gigabyte transfer fees on my iDevices, AT&T wants me to pay more money to tether to my laptop. Why the fuck should they care? The data is the data. I understood when the idae was that a tethered laptop would use assloads of data on the nominal "unlimited" plan exceeding their modelled costs, but...dude, I bought data transfer. why do you give a shit which device the packets end up on? I HATE THIS. It honestly annoys me more than if AT&T just built in the tethering to the price and I just had to pay it.

6 reasons why I don't want you to outsource your project to me.
The article is more or less missing the forest for the trees. What matters is the quality of the comments, not the quality of the karma scoring algorithm. Changing the algorithm might provide someone with more information about my posting habits, but it doesn't provide me with any better editorial feedback - that comes directly from upvotes and downvotes and the threads I choose to comment on (a sincere reply to a personal dilemma in a low upvote AskHN thread might get an upvote and might not - while well timed snark might get twenty-five points...and the first link to a Macbook Pro refresh might hit 200.

Cumulative karma scores probably correlate to long term contribution, but they don't meaningfully reflect daily contribution because some days the best contribution I can make is to shut up and listen.

I agree with you that "bad teachers" is not the core or only issue. A more serious issue, as an example, is that good teachers are actively driven away by petty bureaucrats. Those that remain are severely constrained in the good they can do. With the advent of endemic standardized testing tied into bonuses and tenure, classes have devolved into regurgitate the answer mode. That issue, of really excellent teaching being punished or prohibited, is only one of many many problems in the system. Easy fixes don't work because there is not just one thing that is the problem. There are many things and the things vary somewhat state by state and district by district within a state.
The analysis in this article is just plain wrong, starting with the headline.

Incorporating location-tagging directly into the status update UI (and extending the ability to tag a location to photos and videos), does not mean Facebook is bowing out of any "war"... It means they are honing in on the right location feature set for their userbase, rather than simply copying Foursquare.

I predict location-tagging of status updates and content will gain massive adoption within Facebook and quickly dwarf Facebook Check-In, which by the way, is staying part of Facebook's mobile apps (at least for now).

"the most popular languages that are in use right now don't support closures (Java, C++)"

That is blatantly wrong. Closures, that is, the implementation structure which stores along with a code pointer the references or values to which local variables referenced by said code are bound, have been in Java since version 1.0. Otherwise you could not write code such as:

class foo { final static int bar = 6; static class baz { int bla() { return bar; } } }

and expect "(new foo.baz()).bla()" to return 6.

What Java is missing (and I suspect what the author is conflating closures with) are anonymous functions, which require closures to function properly for the same reason inner classes require closures.

Closures are not anonymous functions. Closures are an implementation detail which allow anonymous functions (among other structures) to act as expected in statically-scoped languages.

Scheme has anonymous functions and closures.

Java does not have anonymous functions but does have closures.

Emacs Lisp has anonymous functions but does not have closures (and thus does not exhibit static scope).

BASIC has neither anonymous functions nor closures.

(It is worthwhile to note that there are other methods for implementing static scope such as alpha-renaming but they are usually much less efficient than closures.)
I don't know how you could possibly tell. Upvote/downvote isn't a very fine-grained tool to express one's opinion with.
RailRoad: Ruby on Rails diagrams generator
Undersea cable technology is fairly mature for data transmission, and rapidly advancing for power transmission (HVDC). You don't need a tunnel for either of those. That leaves the oil pipeline - which I am having trouble understanding the benefits of, because both Russia and Alaska+Canada have oil reserves, as well as more ready access to large oil markets (Europe and the continental US, respectively) that do not first require piping the oil across each other's territory.

I did work a summer job this year! I am learning Rails! I definitely know the idea isn't as valuable as the execution! I went to SW NYC in June and formed a team that didn't have any programmers, but still validated the idea. In the meantime I have been talking to businesses asking them for feedback. I have been toying around with ideas that would be simpler to implement. It's not that I haven't put a lot of time into it, it's I just don't have enough money to pay a lot for a prototype! Thank you for the feedback, and I would still love to talk if you're interested!

Why does the iphone lack basic setting apps?
I recently switched from an Android Incredible to an Iphone 3. The Android was not as stable as the Iphone but the platform had some very useful utility apps - namely, there were (many) apps that would allow me to adjust the screen brightness from the home screen, which I need to do regularly. Incidentally, the auto brightness really worked on the Android and seems to do nothing on the Iphone. Also, there was an app to show the state of and quickly cycle the ringer between off, on, & vibrate. (I am constantly forgetting to turn back on my ringer switch and it's odd to me that there is no indication on the screen of its state.) Beyond that generally, the Android seemed to have much more of these types of practical utilities. My question is, from a developer perspective, is there a reason that Iphone apps seem to skew toward 'soft' or 'fun' applications and lack such basic utilities? Or is it just that Iphone doesn't allow developers to access such settings?
Someone complains about every possible interview question. This isn't the best, but it's not the worst, either, at least not if the interviewer expects a conversation rather than a "perfect" answer.

If you fail the interview because you assumed "integer" meant the wrong thing, then maybe you deserved to fail. You should have asked what the interviewer meant. They could have meant mathematical integers (possibly only positive ones), 32-bit ints, 16-bit ints, "bignum"-style integers, etc. If you fail to ask for clarification, then at best you deserve to have the interviewer choose a different definition and then reveal that after you've wasted time assuming 32-bit ints. Ask for clarification and don't simply assume when there are multiple possibilities.

And you're neither correct nor especially clever for answering 2^32 if the interviewer tells you the question is about 32-bit unsigned ints. 2^32 is not a valid unsigned 32-bit int. This answer is either nonsensical or incorrect, depending on how we interpret it.
Yeah, it's been tough, but I'm still reluctant to outsource the work. The first project I ever worked on I ended up wasting $1000 outsourcing coding work for a site that barely worked and a terrible interface.
LinkedIn definitely has its good and not so good parts, but overall it's an excellent tool for startups. It's great for business development, seeking out strategic partnerships, and reaching out to other professionals in your industry. It's also a great reality check for web startups with little experience in their specific verticals; you can almost instantly communicate with experienced professionals to measure demand, get feedback and even new customers. There's nothing out there that can match it for now.

Also, where else can you find so many "Social Media Marketing Experts" in one place ;).

Plus, Java does have anonymous inner classes, which can be used in a fashion pretty similar to lambdas although with clumsier syntax than most people would like.

Yours is a crucial point that I think got munged in the Java 7 closures debate, since a lot of Java people didn't know what closures were, and a lot of people on the outside maybe didn't know what Java lacked or didn't lack, so there were definitely a few blog posts that conflated them with lambdas.

I don't think this signals a victory for Foursquare. Do they even make any money? I don't use the service myself, but my only interaction with it is rampant annoying updates from people I barely even know on Facebook. I never thought the "check-in" was a terribly useful feature anyway, but more of a cool new display of the power of geolocation.

I always thought it would be far more useful to build these services out as a way to allow people to quickly find each other in one-to-one, as opposed to unsolicited one-to-many, updates. For example, I think a more common use case would be to pull out a phone and alongside a contact have a single button to query for location, then on the other end have the user just as easily transmit his or her location. That would fix the privacy concerns as well.
Gold is not money. Gold is an asset. Dollars, Yen, Euros are money. Assets can be converted to money but assets are not money. Money is something that is commonly and readily accepted in exchange for goods or services.

Can gold be money? Sure if everyone accepted it but shells, cool rocks or toe nail clippings can be money too.
I don't think they should. In fact I hope they don't.

Aside: if you want automatic downvotes, suggest that Groupon might be viable.

Since downvoting erases, it should definitely not be used for simple disagreement. It should be used on poor arguments, bad faith, pointless posts, etc.

It's harder to suggest that upvoting should not be used for agreement.

Regardless, in both cases, I prefer that voting be used to evaluate quality.

"Grid computing" is going to need more than speeds similar to 100mbit Ethernet. "AI" has been around practically since computers were invented, so I am not sure how the "first iteration" of AI will be created thanks to these higher speeds.

Test4Theory is typical distributed computing setup with "small" datasets that require high processing time/simulation to get results. It's not like they are streaming live data from the LHC to your computer. They rely on an actual distributed/grid computer to do that.

Also next gen FPS will certainly not require or take advantage of 100mbit connections because most people don't have them. No one is going to make a game that comes near needing 100mbit/sec.
I hate LinkedIn with a passion, always have. It just seems like an old, kludgy online dating site (like Match). I never use it unless I have to, and I still can't figure out how to turn off their damned weekly emails - they have no easy unsubscribe option and I've gone to their "notification management" (or whatever it's called) area in my account several times, without any clear option to turn off the emails (wtf?!).

Game devs are not interested in making games that no one will be able to run. Regardless of the benefits of raytracing it is currently inefficient when compared with raster tech currently on GPUs. Hardware tessellation makes inefficient voxel tech moot except for scientific purposes. We can already stream data from the hard disk to the system ram into GPU memory.

I'd put mainstream voxel/raytracing tech as more like 10 - 20 years in the future.
Tablets of that form factor predate the iPad, but used a stylus rather than a touchscreen. The iPad was an evolution, not a revolution (technologically, certainly has been a business revolution)

The publication of the source code was not a defensive move. It predated the clones - it was a time in which it was customary to include schematics with manuals (I still have an "XT Technical Reference" at home which includes full schematics and commented bios source code.
Could you mitigate that by having a separate process to do the crypto, which the plugin talks to by IPC? The separate process is then the one that prompts for the password.

This explanation did not add anything to help me better understand closures and anonymous functions. I already understand that closures allow you to pass an anonymous function around and it maintains the variables that were in its scope when it was created (whether by copy or reference).

The problem, at least for me, is finding a non-trivial example of using an anonymous function. Does anybody have other examples like malkia's[1] that demonstrate why anonymous functions and closures are useful? Or maybe just a good explanation of functional programming?

Pretty big double "if" - it may not even be physically possible.

Energy density of diesel: 45.4 megajoules / liter

Energy density of a lithium battery: 1.30 megajoules / liter

"Same weight/energy ratio" (using volume as a proxy for weight since the lithium battery does not have a energy density by weight listed) is 40x.

"Charge time" of a diesel engine is probably also 40x (to pick a number) faster than battery charging (e.g. several minutes vs. several hours).

Multiply the two together and you have three orders of magnitude between the two "ifs".
