In the Mars trilogy (Red Mars/Green Mars/Blue Mars) by Kim Stanley Robinson, the term "areology" was coined for describing geology-on-Mars. I always thought that was a great word.

I think the theory you're referring to is called the Tragedy of the Commons.

$40 for a light, and better contrast, and better resolution. 800×600 was getting pretty long in the tooth; cramming 1024×768 into the same space may not sound like much, but I'm looking forward to the higher pixel density for sure.

Nope, that'll just get you the addresses being freed. This, on the other hand, seems to do what I expected:

    dtrace -n 'pid$target::free:entry { printf("%s: %s", probefunc, copyinstr(arg0)); }' -p <pid>

I'm surprised he went to the trouble of using `DYLD_INSERT_LIBRARIES` - DTrace makes this sort of thing trivial.... something like:

    #!/usr/sbin/dtrace
    pid$1:$2:free:entry
    {
        printf("%s: %x\n", probefunc, arg0);
    }

would do the trick, I think.

Every time I see a post like this (including Paul Miller over at the Verge), it reminds me of an obese person suddenly deciding to go anorexic. You know what the problem is? It's not the food. It's self-control, plain and simple.

When was the last time you looked at RAM prices? You can get 32GB now for $100. (Complete insanity.)

How is Penny-Arcade's Kickstarter allowed then? (Not disagreeing, but it seems like they would run afoul of this if it were actually enforced.)

xargs is so 20th-century. parallel[0] is way more awesome (especially with all the multi-core systems everybody has now). Cool bonus: all the things you learn for xargs work in parallel too!

These times are for spinning-platter hard drives. I wonder what the numbers look like on a modern SSD?

If you do:

    #!/usr/bin/env scala
    !#

it appears to work.

I wonder why they don't use

#!/usr/bin/env scala

as the first line instead. If there's some hack to support #!/bin/sh in the scala interpreter... ew.

Apparently node.js doesn't implement the DOMParser object, which means that you can't actually use jquery's parseXML method. That's a bummer :(

Depends on whether or not your side project uses more than 5MB of database storage. I'm running a tiny node.js app on Heroku and you get up to 750 hours per month of free CPU time, so I haven't paid a dime (but I am really in love with how slick everything is).

Is anyone else stunned at how quickly Heroku has been pumping out new hotness? I was kind of worried when they announced they were being acquired, but if anything, it seems like being acquired has increased their pace.

> Microsoft does not launch unfinished Xboxes (hardware + software product).

Tell that to the millions of Xbox 360 owners whose consoles died with the red ring of death.

Approximately three months.

This article from Gruber in 2008 seems eerily prescient now. http://daringfireball.net/2008/05/blackberry_vs_iphone

Not that this helps you since there are no Thunderbolt peripherals yet, but supposedly Thunderbolt will let you daisy-chain multiple displays from that one port.

Because MessagePack doesn't work in MacRuby.

I would love to play with a Maple mini. How do I get one?

I stand corrected. That makes sense (even if it is frustrating).

That makes no sense at all to me.

If your IPv6 is working you can't go to the site to test it unless you also have working IPv4.

There is absolutely no reason why test-ipv6.com can't have both an A record and an AAAA record.

Nobody is ready for IPv6 yet, and it's depressing.

I tried an experiment the other day, turning off IPv4 and using only IPv6 on a desktop at home. HN, Ars Technica, Twitter, Facebook... none of them even have an AAAA record. Google does for the main google.com site and for gmail, but not for Google Talk. Hell, even test-ipv6.com doesn't have an AAAA record.

If you're willing to go up to 469PLN you could get a previous-generation (still basically pushing the limits of SATA2) Sandforce-powered 60GB SSD.

Some of the first-gen SATA SSDs (based on the JMicron 601 and 602 chipsets) had nasty stuttering problems with lots of concurrent writes, but pretty much every SSD made in the past 12 months is going to blow away any spinning-platter disk when it comes to random writes. SSDs based on Sandforce's 1200-series controller can do 30,000 IOPS, sustaining more than 150MB/s with 4kB random writes.

You should probably investigate the current hardware (OCZ's Vertex 3, Crucial's m4, Intel's 510 series); it might surprise you just how much better it's gotten in such a short time.

I love how everybody seems to have forgotten this one...

What browser are you using? It looks great to me here in Chrome and Safari.

This post would be so much more useful if it had a list of the questions asked, what the wrong answers given were, and an explanation of why the answers were wrong, along with links to the information needed to come up with the right answer.
