I don't agree with the downvotes here. I tend to think people downvote short comments without really attempting to understand the value they're bringing to the conversation. Conversely, people assume a long comment is insightful.

It is a reasonable explanation that any increase in intelligence is just the subject getting better at the tests that are measuring intelligence. If you take the same IQ test over again, you're likely going to score a bit higher. But this certainly doesn't mean the act of taking the test made you smarter. You're simply getting better at using the tool used to measure intelligence.

This made sense at least before the most recent study cited with the Dual-N-Back training. You're going to be hard pressed to explain that away.
To clarify, my definition of hacking is inspired by this http://stallman.org/articles/on-hacking.html
I meant literally the word "shit". Your point is completely valid.
I know most people do not sell their artistic works. I was referring to hackers with that "possibly".
Not indefinitely. Eventually you will likely run low on novelty.
I'm not sure I understand you fully - are you suggesting that the main problems with that project would have been solved by simply updating to Windows / SQL Server 2008? I can't believe that would possibly be the case.
Try to fit math ideas.

What does zero mean? what does one mean? does addition make sense? can you take the limit of something? What if something blows up to infinity?

So... try cars. zero being no car. one being a "standard" car. say a honda civic. how much honda can you take a way and still be a car? like taking the limit at zero. There are crazy efficient cars with tiny little internal combustion engines and bicycle wheels that get 100+ mpg but piss poor acceleration. hmm. what would a car be at the other end? a ferrari? Do cars associate? do cars commute? :)

Creativity isn't painting. It's looking at the same crap you look at all the time and playing with it. Math has a lot of tricks for labeling things, then seeing what shows up when you try do stuff with the labels. New dimensions will pop out.
Feedback for my website
Hi,

I've just launched a new website and would much appreciate your valuable and honest feedback.

Webifieds.net is a classifieds website for internet-related classified ads (or in otherwords, classified ads for anything online).

I would appreciate your feedback on the design and usability of the site, but also on the idea and the name (by the way, Webifieds comes from Web + Classifieds).

Many thanks.
Why the downvote? it really does look like a hoax.

Plus when people say "flaying car" I expect a sci-fi like flying care: that it can hover and fly vertically, not have a parachute-like thing attached to it.

This one really almost looks like an april fools joke.
This is solid. The team is not going to leave as a whole as much as any business would abandon a healthy (or maybe not so healthy) customer relationship. I also think that people will leave the team for the same reason they'd leave a healthy employment relationship: startup opportunity, education, family, retirement, etc.

If the whole team does decide to move on, it's likely that the set of circumstances that would push a "packaged team" like this away would probably cause mass attrition with normal employees as well. Just today a friend of mine told me the 2 layers of management between him and the CEO quit on the same day, and he's feeling like he wants to quit now as well. So goes the pack.
Many contracts have non-disparagement clauses which prevent you from making public comments about the company.
Depends on your demographics. My mom would hate it, dad would mistype it, I don't know how to pronounce it. It's not related or associated with anything in the daily life, and there is a disconnect between the spelling, pronunciation, and meaning for the layman. Only works for math, history and language buffs. That's a tiny corner.
Wisdom is knowing which shortcuts to take. But there are no shortcuts to wisdom.
Isn't Facebook doing the same thing? In fact, I just got an email from them today that they're forcing the issue and all devs must adopt oAuth by September.

Stars are balls of matter massive enough to sustain nuclear fusion from their own gravity. The fusion reaction is what releases all the energy.
Unseated.
Excellent post. It's made me realise how much I have been taking the easy road lately.

I used to always be looking into new areas to learn about new things and really pushing myself, but I realise now that lately to solve a problem I reach for a familiar way to solve it, because it's easier and faster. This could be the reason why I am getting less satisfaction with solving problems lately.

Time to get back on that horse...
I like the overall idea a lot and am working on something vaguely related (though more like Quicksilver/Gnome-do).

I doubt that a modern approach is going to be able to satisfy the entire historical legacy of the Unix terminal and it probably shouldn't. Everyone who's happy running vi in an ordinary terminal should probably continue to do so.
What I find interesting here is that you focus a lot on mathematics instruction in your comment. In my opinion there's much more that influences learning outcomes and outcomes on test results than math instruction techniques, namely student self-theories and various systems having to do with the existing educational paradigm. I believe those factors are involved and a culprit for sub-average results equally much if not more.
The main gist:

"mmap() interface is missing a non-blocking way to access memory."

At the end of the day your process will still be suspended when the page is brought in from disk the first time it is read. In some situations, when you can't afford your thread to be suspended waiting for disk IO (say if you could do something else in the meantime, like service network requests) it would be better to use AIO for example to schedule a file read into a buffer and be notified later when it is finished ( http://linux.die.net/man/3/aio_read )
I take exception to the 'Think Creatively' item. It's kind of like making a to-do list with 'lose 20 lbs' as a line item. Much easier said than done.

That being said, I think one of the best ways to improve your creative thinking is to work directly with other people that YOU consider to be creative thinkers. At my previous job I always enjoyed working with the CEO, sales, and marketing folks because they almost always approached problems from a completely different angle than I would. Experiencing how others ideate is very mind opening and often times humbling.
I don't believe/think that consciousness/awareness is a property that can emerge from running a brain or a brain model.

But, even if it were: a computer simulating my brain will not be me; I will not experience what it experiences.

Suppose someone came from the future and claimed to be "me"; that is, 20 years from now I will go to the past; or something like that. Let's call the future me F and the present me P. I'm P, when P sees the color red, it's me who's seeing it. But, when F sees the color red, P doesn't experience the same thing. (it will experience it 20 years later, when it becomes F).

So if a clone of me experiences something; I won't experience it.

So if you upload my memories to a brain and then torture that brain, you wouldn't be torturing me; you'd be torturing a machine that happens to have my memories. In the same sense that if you clone me then torture my clone, he will experience the pain; but I won't.

If I do experience the pain of my clones, then we (me and my clones) must be telepathically communicating, or something like that, which, while philosophically not impossible, it's not compatible with physicalism, which you have to accept if you think consciousness can arise from running a brain model. I say telepathy is not compatible with physicalism because telepathy implies a super-natural communication between minds (where minds are implies to be super-natural entities).

I think it's a good idea, and I'm not even sure you'll have as much of a problem getting some feedback as others think. My only contribution is that I hope you are aware of all the privacy concerns with this. It certainly isn't a huge deal, but I figured I'd mention it in case you hadn't considered it at all.

In the US, I believe it falls under HIPPA and the Protected Health Information (PHI).
The original article is from four years ago. Here's an update: http://www.newscientist.com/blogs/shortsharpscience/2011/05/...

Alas that headline, like so many in this space, is misleading and converts promise into something a lot more definitive.
Yea I know, of course it is not PR 2.0 compliant.
Settle now. State your intentions and expectations and make sure both of you are on the same page. That "good friend" can head south real quick when the cash registers start ringing and disagreements arise at that point.
mmap is great, but it often lures developers into thinking that in-memory and on-disk data structures can be reasonably unified. It's still spinning media, and even SSDs are orders of magnitude slower than regular RAM. Optimized data structures should be used accordingly.

It's also not a hard rule that the OS cache is always better. It's probably very good at block-level caching, so don't rewrite that, but that's not very fine grained. The OS can't collect much more than some basic access statistics and madvise()s to figure out what to keep resident. It's kind of dishonest to make it seem like "advanced databases" like PostgreSQL should abandon their own caches entirely. In fact, most PostgreSQL tuners suggest that only a fraction of available RAM should be used as a buffer cache, and that it's prudent to just let the OS manage most of it. The query planner can even be advised as to how much effective cache space is available, including the OS disk cache.
I'd say they are interested, if they're paying to bring someone in to talk about it. There are all kinds of reasons that they might be interested, and I'm curious to know which ones apply here :)
I really doubt that would have changed people's reaction. Besides, to be taken seriously, I have to believe that TermKit can eventually be a fully functional replacement.

As for being hard to try and not at a useful stage yet... hey, that's not my problem. I wasn't the one who upvoted it all over the internets :).
SAP and BusinessObjects on Amazon EC2
"Taking the sum is itself expensive, though (in terms of logical operations)"

"the least significant bit of the sum is by definition the parity of the set, so calculating the rest of the sum will only increase the number of operations required"

Can you expand on these two statements please? Examining the sum seemed like a more elegant solution when thinking in terms of higher level languages but the extent of my knowledge ends there. I'd really like to understand how sums compare in terms of actual operations.
That's not really much of a consolation.
Another problem with mmap not mentioned is that not all file systems support it. Filesystems like jffs2 which access NAND flash don't support mmap.
It's interesting to see Amazon & Google directly competing, to the point that Google rushes a seemingly incomplete cloud music offering (also without label consent) to counter Amazon's early control of the market.

They're also competing in cloud infrastructure, android app markets and streaming video services. Their fundamental services are not that different, both centered around search, though they don't really compete for it. Amazon is a retail service but part of their effectiveness is showing you what you want.
You can not even begin to understand what micromanaging users' installs is like until you have tried it. You will either change your tune quickly or bring on a whole team of people to focus on that goal (which is what the large companies do).

> it keeps apps from "playing dumb" when they
> give info to a third party.

What companies are giving out usernames and passwords to 3rd parties, and then trying to 'play dumb?' It seems to me like you're talking about companies that sell your email address to 3rd parties, but that's a whole different ballgame. At the risk of venturing off into bad analogy land, you're claiming that companies are giving away the keys to your house (to 3rd parties), when you really mean that they're giving away your mailing address (to 3rd parties).
Added to my todo list. Thanks, didn't know about this one.
The difference is in whether escaping is necessary. What happens when you no longer need to escape things? It no longer matters which quotes you use.
He focused on mathematics because that's his current field of expertise.

I'm not sure what you mean by "student self-theories and various systems having to do with the existing educational paradigm", but axiomatic mathematics instruction leads directly into analysis, problem solving, and general logic; while that doesn't justify an educational curriculum consisting solely of mathematics, it does make it very important.
Why is that? You will have to explain your odd view a bit more, I fear.

I can understand that some people prefer PC gaming for one reason or another but I think I’m quite correct in guessing that those people are a tiny minority – it’s a niche.
There were times in my life when I woke up (from normal sleep) thinking I didn't sleep at all, while in fact I slept for hours and hours.

Well, a few years ago I made this Line Rider video, and then 10,000 people on YouTube told me to get a life.

Well the likelihood that this becomes popular and allowed on road (imagine if everyone was to flyoff in the middle of a traffic jam, you'd get air jam and probably planes hitting each other).

It's more likely to be used in remote areas like in the middle of Ecuador as Steve Saint the guy in the video was hinting at. Or like here in Canada, some areas in northern canada aren't accessible by road from the south, this could fly the required miles to reach the next road. (well it would have to be better insulated and fly a little faster considering the distances).
Yeah, the TL;DR thing really grates on my nerves. Are we so miswired now that we can't take the time out to read 4,500 well-written words on a subject, and instead need it condensed to a list appropriate for Twitter? Is there really no other value in the entire essay other than the list items themselves?
Processes in a computer can create input/output between each other. If the brain is just another program, why couldn't some other program running inside the same computer send it inputs?
At this point in your career path, I would say that both offer an experience from which you will be able to judge the kind of environment more suitable for you.

If I can make TermKit deliver on its promise, then I'm pretty sure on of you vim guys will take a VT100 JS emulator and make it work in TermKit.

The recently posted show HN for that analytics site was very slick and sharp as well.
The author juxtaposes his recommendations against his unnamed professor's claim that intelligence is genetic and fixed at birth, pointing out that there are broad classes of behaviors that can improve our intelligence -- but he neglects half of the response to his professor's genetic predestination view, namely the whole host of physical/chemical/biological factors impacting both brain development and cognition later in life.

As just an example, I was recently impressed by a study (http://rspb.royalsocietypublishing.org/content/270/1529/2147...) demonstrating improvements on both a memory task and an intelligence task through creatine supplements. The explanation suggested by the authors (and it looks like some other literature as well, though I haven't really dug into it yet) is basically that creatine is part of a mechanism for rapid ATP synthesis, that the ion pumps in your neurons run on ATP, and that if you're sometimes "fuel-limited" (their word) creatine levels matter, in the same way that oxygen and glucose do. This make sense, but I was quite surprised to read this, I think in part because I'm used to seeing my brain as being a relatively static thing. Stepping down a level of abstraction, and thinking about the instant to instant chemical resource needs of individual cells and gates is kind of eye-opening. And for all I know there's hundreds or thousands of other documented effects, where increasing or decreasing the presence of some reagent associated with running ion pumps, or growing axons or synthesizing neurotransmitters has some measurable effect on intelligence.
And yet somehow I don't think music consumers of the world will be better off for it.
Thanks for bringing up this great point.

I actually built in anonymous usage logging into TermKit using Google Analytics over SSL. It logs the types of commands you execute (no data). It's my plan to release this data back to the community regularly. I don't think anyone has done a large-scale survey of command-line unix usage before. Should be interesting.

Edit: and you can easily turn it off if you wish.
At some time microsoft might have to realise that creating gimped editions of windows makes people assume windows is gimped.
Hmm. So, according to #2, I should be able to help increase my own intelligence by playing Sudoku?
My addition (6): observe others, be inquisitive about other people. This will not only help you appear smarter to others (believe it or not, there is such thing as behaving/appearing smart), but will also help you with networking because (a) people respond positively when someone displays genuine interest in them (well as long as you are being nonthreatening) and (b) smart people tend to seek out others like them.
Startup Turns Your Old Stuff Into Charitable Goodness
It's not real Cloud Music until it's performed by Brian Eno — or perhaps it's more similar to gas music?
I have no doubt that math teaching methods in the US are terrible, in general. And I am very open to the possibility that Singapore does it much better. But however poor Singapore was in the past, it is now 3rd in the world in per-capita PPP GDP while the US is 7th (according to the IMF; $56,522 vs. $47,284).

Furthermore we should always expect the top countries to be small ones; if each state in the US (pop. ~300m) was considered individually, it seems very likely that several would be more highly ranked than Singapore (pop. ~5m). Seeing as that those states are much more alike to the rest of the US--in terms of culture, government, etc.--than is Singapore, shouldn't we be looking to them for guidance on how to improve the rest of the US?
None really. I'm in the same boat.
The mechanism suggested by the author seems a bit absurd. Code would to have to pre-warm regions of memory to be available in a non-blocking fashion before accessing it. One of the major attractions to mmap() is that this is unnecessary, the OS handles all of the read-ahead and caching for you.

It also seems silly to go through all of this, but end up using a thread pool to perform the page faults, which brings back the issues of thread starvation, context switches, and lock overhead which cooperative concurrency models try to avoid.

I'm trying to think thru all the scenarios, but it doesn't seem as if it's really practically possible (in C at least) to make mmap() I/O work in a cooperative concurrency model.
I don't mind, the project is in too rough a shape to interest anyone but hackers. Please come back in a month.
The photos are removed once the posting is no longer live on the site (roughly). As for how many, I'd have to dig a bit to find that out...
I found this interesting (regarding Go): "we started off with the idea that all three of us had to be talked into every feature in the language, so there was no extraneous garbage put into the language for any reason".

As a fan of minimalism over complexity, I like the idea, but I can't help but wonder if three of the world's best programmers are the best qualified to decide what programmers in general need. For example, if you can dash off a correct, performant, and theoretically sound version of a data structure in a couple dozen lines of code and 15 minutes, I bet generics seem much less useful.

However, I do prefer that to designing to the lowest common denominator.
I don't think that's what I meant at all... fwiw. I'm saying working on things that help them articulate visually their ideas quickly.

The act of learning a bit of HTML/CSS or Rails/PHP/etc makes the non-technical founder a better non-technical founder, but my suggestion is to focus on tools that improve the conveyance of ideas/features/etc. shrug
http://sourceforge.net/projects/brainworkshop/ is an open-source implementation of the dual n-back test for Windows, Linux, and OS-X.

"Following training of working memory using the dual n-back test, the subjects were indeed able to transfer those gains to a significant improvement in their score on a completely unrelated cognitive task. This was a super-big deal."
When you hate your design and you're almost finished with it, what do you do?
The last sentence of the interview "Google makes us do that" is very interesting. It's not that Ken is convinced it is a good idea, it is that Google is forcing him to do it. Google knows best after all, implied is that Ken is nobody so special that he can decide how he himself works best.
