jjs··on Genetic algorithms, Mona Lisa and JavaScript + Canvas
Next step: run a genetic meta-algorithm to optimize the initial parameters... judge fitness based on, say, result_quality / runtime...

(Or fastest-to-achieve-reasonable-result...)

Not "Bros.", "Land"... (This game was a formative experience for me, so please bear with my nitpickery... :)

jjs··on Last of a Breed: Postal Workers Who Decipher Bad Addresses
Either that, or they've spent so much time on the pre-Unicode Internet that they can sight-read Cyrillic characters encoded as Latin-1...
jjs··on Simple Raspberry Pi Rack
Idea: each Pi could be placed in some carrying case (with power, external sensors, e.g. GPS), and individually taken out in the field.

Then, when the Pis are back home and networked together, they connect as a cluster and reconcile their individual data...

> $9 seems quite excessive to mail a sheet of paper.

$9.83 is a Starbucks grande latte in Oslo...

jjs··on Paypal President: We're thinking about adding Bitcoin (2:50) [video]
There's the value: a trusted* escrow service.

(* Well, within the known limits of how far Paypal can be trusted. )

jjs··on The Silicon Valley Toxic Waste Heat Map
> Okay, so the entirety of silicon valley is a toxic waste dump?

Yes, notoriously so. Think about where the name Silicon Valley comes from. HP, Shockley, Fairchild Semiconductor, Intel, AMD... Chipmakers. A lot of dangerous chemicals go into silicon chip fabrication, and a lot of them, especially in the bad old days, weren't disposed of (or contained) properly.

> "Never mind that Jobs is the quintessential malicious and inquisitive meddler,"

So, the bad definition of "hacker"?

jjs··on JQuery 2.0 Released
Deprecating old-IE is the solution for cross-browser issues.
jjs··on The Well Deserved Fortune of Satoshi Nakamoto, Bitcoin creator
Reboot? Anonymity (and liquidity!) seems more feasible with multiple viable cryptocurrencies coexisting.

e.g. using an exchange site (which has legitimate reason to exist), sell Bitcoins for Litecoins, then sell Litecoins for Bitcoins of different provenance.

jjs··on Bitcoin: Whatever It Is, It's Not Money
Given the dollar's recent volatility in terms of Bitcoins, I hardly see how Forbes can argue that it has a fixed value...
jjs··on [dead]
The Buddha you meet on the road is not the one you're looking for.

Consider the koan:

    Does a dog have Buddha-nature?
    This is the most serious question of all.
    If you answer yes or no 
    You lose your own Buddha-nature.
What I got from this one is that the dog question is meaningless until you can answer the real questions it implies: "Do I have the Buddha-nature?", and "Does such a thing actually exist at all?"

Eventually you'd run out of lives...

jjs··on If You’re Going To Kill It, Open Source It
That assumes that people would adopt a code dump that's net-negative in value. More likely, they'd salvage just the good parts.
jjs··on The Lisp keyboards
You can have a Hyper key (in X11, at least!)

http://computing.fnal.gov/docs/products/xemacs/v21_1/xemacs....

Depending on your keyboard layout, the "Menu" key makes a good Hyper, and if you've set up Caps Lock as an extra Ctrl key, you can remap your left Ctrl key to something useful.

You can also separate Alt and Meta to different keys.

A quick emacs session will show you whether your new modifier keys are working as intended.

IIRC you can do similar for the (text-mode) Linux console as well.

jjs··on Ian Bicking: My Unsolicited Advice For PyPy
Have your cake and eat it too: open a socket to a CPython process and let it handle the legacy C extensions.
jjs··on Yuri Milner Portrait
Perhaps he's merely trying to depolarize investors' opinions; if everyone second-guesses him in a different direction, it might temporarily stabilize the average valuation.

jjs··on Show HN: Quick joke project
Hmm... 67% of users agree that "Swedish Opera Singer" is indeed a good snack.
jjs··on Torvalds: Standards are paper. I use paper to wipe my butt every day.
> Seeing this purely as a spec v pragmatism issue isn't going to get us anywhere.

That's because it's not.

The spec ( http://pubs.opengroup.org/onlinepubs/009695399/functions/mem... ) explicitly states, "If copying takes place between objects that overlap, the behavior is undefined."

Which means the real debate is between two technically valid interpretations of the spec: one that arbitrarily breaks existing software for no discernible benefit✻, and one that does not.

(✻ Unless, for ideological reasons, one believes that breaking said software is the benefit, in which case this is still a sneaky and passive-aggressive way to go about it.)

It's even fair to cast this particular debate as nonsense vs. pragmatism, because that's what it is.

Isn't that the basis of all voluntary transactions?

jjs··on Most common one-line bugs in C?
> There are some very wacky calling conventions out there; among them, "caller reserves space for result on the stack after the function arguments".

Well, that's not very tail-call friendly...

jjs··on VLC Developer Takes a Stand Against DRM Enforcement
> anyone who doesn't want to subsidize Apple's dystopian future will choose to buy a competitor's product whether VLC is on iOS or not. The only party's substantially affected here are iOS users, who are now deprived of a program to play more video types.

If you don't like Apple's dystopian future, then reducing the incentives to own an iOS device sounds more effective than merely not subsidizing the platform.
