* I'm not claiming their exact numbers apply in this situation.*

You see, the thing is, you kind of are making that claim. If entropy goes out to 3 bits per character, the one feeble point that you did have gets blown out of the water. The fact that you don't seem to understand that indicates that you really need to go back and reread a few books on Information Theory.

Look, for your own edification, try and come up with a scheme that will reliably beat a dictionary attack in terms of the number of attempts needed before finding a password taken from the dictionary. You could even write a simple program to test the idea. Take a dictionary of 5000 words with a length of 6 characters or longer (much shorter words than what your theory suggests should be secure). Select 100 words from the dictionary at random, and then run any attack of your devising against those words. If you can reliably get a better average number of attempts than 2500, I'll concede the point.

Until then, I'm here to tell you that you don't understand information theory as well as you seem to think you do.

Couch's map-reduce is quite slow for ad-hoc stuff. It's excellent for frequently viewed data (as you can get stale views, and new views are sort of incrementally done), but it's slow to set up.
Yeah I am serious - I tried a number of things but at least my state is not so extreme anymore. I have quit soda and energy drinks, and only drink 3 shots of espresso (maximum) per day, which is under 300 mg typically (within the "acceptable" range for caffeine intake). I try to minimize my sugar as well and do not put any in my espresso, just milk.
screen is one of those things that's been on my todo list for way too long, along with its alternatives(?), tmux and byobu. Anyone that uses/used all three and can offer a comparison?
In an environment where every byte and cycle counts I'd be using C. C++ has too much stuff going on behind the scenes. (Like hidden object copies, potentially bloated operators, etc.).

If you can live with enabled exception handling (which is a performance toll) then some additional object meta data shouldn't be a problem.
Maybe some of the grade improvement is real. The Flynn Effect has recorded an increase of 3 IQ points per decade.

Apachebench (ab) is a decent alternative to siege, and knowing how to use tcpdump and netcat comes in handy for debugging.

If I need to completely reproduce my production environment on a test box, it's my utility of choice.
I certainly wouldn't consider signing up with that little information.
> Well it's like a guy coming up to a bowl of free candy in a place where everyone already has their pockets stuffed with candy, then going to some other place where people haven't got any candy and giving the candy to them.

The merits of that action aside, we don't actually know that's what he's going to do with the money from eBay. We do know that he's going out of his way to convert it to cash, and we also know that he's gone out of his way to make himself seem less trustworthy. Given that cash is fungible and he wants to promote the idea of giving to charity, you'd think he would have given what he expected to make off the card to charity and pointed that out up front, if giving the money to charity were really his intention.
I agree, but you are talking about technical features again. The interface for circles is slick, it allows new technical fun. I think this is why Google+ is pretty popular with the tech crowd. But now, one month on, even though 60% of my Facebook friends join G+, none of them are using it. My feed is littered with celebrities that overpost because circles are great for limiting who you share with, but poor for limiting what you view. (Google doesn't let you say: show me every circle but X, and if you choose to view a specific circle it will always reset to all)
Must it be the civilized versus the savages? Are you sure that's a fair description?

How about this: it's my laptop, and I reserve the right to use it to take pictures any time I see fit?

I'm okay with running the picture of the guy, and publishing the data, as long as there's a clear disclaimer that this is just information pulled from your own laptop, not presented as evidence in some kind of criminal proceeding. We do this all the time with videos on the news that show crimes in progress. Heck, we did it with the rioters. Local papers ran big pictures of them on the front page. Simply making public video and data that you have every right to have and use isn't the same as calling the guy a crook and demanding he be hanged.

Now yes, the mob will probably take over from there, but that's because the net is full of mobs, not because you've somehow made a mistake in publishing the data. I am very concerned about folks taking justice into their own hands, but I don't think that my concern somehow changes the right of this guy to publish his own data.

There's no "we know the bastard did it, so there" that has to be involved. I load my laptop up with whatever legal programs I like, and I choose to publish the data from those programs any time I feel like it.

I actually waited in line at a bank for about 15 minutes once, and when I got to the teller the manager said "hey - want a coffee?", and handed me a Tim's card (reloadable gift cards for Tim Hortons). I had no idea what the value was - but it turned out to be $2 (just enough to buy any size of coffee at Tim Hortons).

Having it be $2 was a lot more useful than having it be for a large coffee - I don't drink coffee, and I ended up using the $2 to subsidize a bagel.

Actually these are only convenience methods.

For example to get a class name you can either use [object className]. Or you can use object_getClassName()/directly access "anObject->class_pointer->name" without dispatching any messages. The same goes for any other runtime attribute of an object.

The standard example is:

void f(int x);
void f(char *x);
...
f(0); // calls void f(int)

That may seem contrived, but you may not know of the f(int) overload, especially in combination with templates.

NULL, if #define'd as (void *)0, prevents that error.
I think this is going to be a steep uphill battle, but if you're willing to band your head against a wall a few times then definitely go for it. I just personally think that publishers are going to be very hesitant unless you come to them with a VERY compelling product (which I have no idea what that would have to be).
And this area is biased in both direction. From one side you have family groups and from other side you have game industry. And there are studies showing both sides. That's why meta studies are needed.

I taught freshman calculus at Stanford. I had little idea what I should expect of the students, and certainly I didn't have any absolute standard of what constituted an "A", "B", and so on.

So what did I do? I just got the grade distribution from the last time it was taught and curved my class the same way. But this wasn't perfect... there would be a clump of five students who all got around the same numerical grade around a cutoff, and I'd round up rather than down. Similarly there were a couple of students who showed unusual effort and/or improvement, and I rounded them up if they were borderline. The end result was a grade distribution that was just slightly more generous than the last time. And hence I perpetuated the cycle.

As a professor, if you want to give strict grades, you have to be able to justify your reasoning when students complain. I don't terribly like grading, I don't have any deep insight on how to do it, and my department doesn't have strong opinions (other than that I should get back to writing my grants). So what do I do? I follow my peers.
Yes, a thousand times yes. I assure you that in the 1970s engineers were telling each other that using 8-bit microprocessors to build “toy” computers was outside of their intended purpose.

byobu is something like a theme or packaged config for screen, so it doesn't really need to be treated separately.

The biggest difference between tmux and screen is that tmux is a lot more flexible with regard to laying out groups of sub-terminals within the main terminal. screen is mostly limited to one-at-a-time, horizontal splitting or (in very recent versions) vertical splitting, while tmux lets you go nuts: http://tmux.sourceforge.net/tmux3.png

Also, GNU screen is very old and stable, while tmux is (so far) still new and flexible. For example, tmux very quickly added support for handling Unicode characters beyond U+FFFF, a feat that (so far as I know) screen still can't manage. That's only one example, but I'm sure there'll be more as time goes on.

EDIT: One other thing that tmux does that makes it better than screen: when I start up a tmux session from within an X11 session, tmux clears the $DISPLAY variable so that processes running inside tmux don't try to connect to the original X server - which may very well have gone away at that point. It's a small thing, but incredibly annoying when it happens.
Initial Thoughts on Clojure
Ask HN:  Anyone working on something in the Senior-Care market?
I'm working with a few people in the Charlotte, NC area on a radio show for seniors and would like to feature a few companies that are bringing new ideas and products to the senior-care market. Was curious to see if anyone in the HN community was working on something related to seniors or their caregivers.
I think a major problem with grading is that it causes teachers to conflate two separate but important measures, effort and performance.

Those uses grades as a guide to acceptance (colleges, jobs, etc) really want to know both of those pieces of data. So they use standardized tests to get hints at performance and interviews, recommendations, etc to get hints at effort.

Maybe what we really need is a new grading system with two scores for each class, one for performance and another for effort.

Here's an interesting tidbit:

"Moderator analyses revealed significant research design effects..."

What that means is that the design and sample selection of the studies influenced the outcomes of the studies to a large degree. Oftentimes, we see this happen in studies that draw from clusters of the population. Clusters are not truly random samplings. So when you take a sample population from a cluster -- be it geographic, ethnic, national, political, etc. -- you're run the risk of not taking a genuinely population-representative sample. Your sample population is likely to be more homogenous than a truly random sampling would be, as seen in a lower variance rate among respondents than you'd expect to find from a random sampling.

This is all well and good if what you're testing is the effect of X or Y on that cluster. But if you're trying to study effects of X or Y on the general population, then cluster sampling is far from ideal.

Let's say I'm designing a study called "National Attitudes Toward Ohio State Football." And for my sample population, I select 500 study participants from the state of Michigan. Would anyone in his right mind believe that my study will produce a nationally representative outcome? Similarly, if I'm doing a study called "The Effect of Gas Prices on Grocery Budgets," I might be pre-biasing my outcome if I select from a cluster of long-commute suburbanites. Or from a cluster of poor people. Or a cluster of rich people. Etc.

It's hard to know what sort of design effects were noticed in the various studies aggregated into this particular meta analysis, or how the meta-analysis attempted to compensate for such effects. But the presence of that line in the abstract gives cause for concern.
How about this: it's my laptop, and I reserve the right to use it to take pictures any time I see fit?

That statement is like saying “This is my gun, I reserve the right to shoot bullets from it any way I like.” Obviously every action we take with our person and our property has consequences and we are responsible for those consequences we can reasonably foresee.

Clearly there is a continuum of choices from sharing the pictures with law enforcement but not publishing them, to publishing them but being careful to disclaim that this person has not been convicted of committing a crime, to publishing them and asserting this is the thief. You pick where you feel comfortable on that line, I pick where I feel comfortable.

Looking at the commentary here and the last two similar things to hit HN, you must accept that regardless of where you or I might place ourselves, there are definitely people to the far right of the line. You can see people talking about this person as “the thief” without bothering with the inconvenience of a trail. You can see people discussing the publicity as a pubnishment. One comment talks about “naming and shaming” as a deterrant.

You may not consider yourself part of a lynch mob, but seriously, can you deny that such an element is present?
> By buying TMO, they would get an instantaneous

Not really. Most of the coverage AT&T is lacking and proposed to build out to expand from 8x% to 9x% coverage is in rural areas where T-Mobile's network is even weaker than AT&T's. In other words, there are very few places where T-Mobile has coverage and AT&T doesn't already; most of the new coverage they'd get in this deal is redundant.
I thought part of the current discussion was "Well, if Apple is giving Samsung grief over selling the Galaxy Tab, Samsung should make life difficult for Apple component-wise." Say if a part was magically "unavailable" for a week or two.

It's hard to tell who has who over a barrel at the moment. At Apple's volumes, can they change suppliers quickly? Can Samsung afford to piss off Apple just to get the Galaxy Tab back on the market?
Thanks for the info.

> C++ has too much stuff going on behind the scenes. (Like hidden object copies, potentially bloated operators, etc.).

The thing is, C++ is usually good about not charging you for features you don't use - and with the reasonably good debugging and profiling tools, most of the problems you mention above are fixable to get performance that is close (or equal) to C, with maybe better maintainability.

To pick a not-so-random example of something that's difficult to implement in C as safely as in C++, see expression templates[1]. I'd be interested in something similar to what eigen does written in C. (Of course, the last time I did this minibenchmark, so-and-so's lapack library was still slightly faster than eigen :)

The bottom-line, perhaps, is that if I'm writing a library, I'd do it in C simply because it's self-contained and has a nicely limited scope, and as a bonus is usable from oh-so-many other languages. If I'm writing an application that really, really requires serious performance, I'd prefer to use C++.

I can't read the article either, but you make a lot of assumptions here. One of them supposes that the authors are idiots, and another one is simply wrong.

Whatever the design, studies without proper control groups are useless. People who do and review meta-analysis are very aware of methodological pitfalls, and the likelihood of seeing a meta-analysis based on such papers is extremely small.

The abstract also mentions that there is no gender effect, barring the "boys" part of your "teenage boys" argument.
