Research Highlights How AI Sees and How It Knows What It's Looking At

geantvert I see the gorilla. (129 comments)

In the pictures from the last link, I clearly see the gorilla and the backpack.

Those images remind me of what you get with some edge-detection filters commonly used to enhance image features.

Sony Leaks Reveal Hollywood Is Trying To Break DNS

geantvert Re:Yeah, that'll work. Sure. (385 comments)

Unfortunately, many (small) websites are hosted on a shared server with one IP for multiple domains.
The name is required in the URL else it simply does not work.
That would also break all https sites.

For example, www.mpaa.org is currently 69.172.201.20 but http://69.172.201.20/ does not work.

NetHack: Still One of the Greatest Games Ever Written

geantvert Re:Starving is far too easy (186 comments)

At first, nutrition can be a difficult problem but after a while you learn what corpses can be safely eaten.
During the first levels also everything is safe except undeads (zombies), kobolds and rabid rats.

You will eventually become weak but your god can solve that if you #pray but be aware that he will only cure one major problem amongst Food, Sick, Blind, very low HP, ...

Once you have killed your first unicorn, you can start experimenting since the unicorn horn can cure poisonning and sickness.
Avoid eating cocacktrices and everything should be fine. In the mid- and late-games, large monsters can produce lot's of meat so food should not an issue anymore.

NetHack: Still One of the Greatest Games Ever Written

By the way, Wizard is probably one of the easiest roles in slashem. The beginning can be hard but the end game is a lot easier once you know Passwall and Magic Mapping.

NetHack: Still One of the Greatest Games Ever Written

geantvert Re:Don't foget (186 comments)

There are several towers in Slashem but I do not remember that any requires a boulder. I suppose that you mean Sokoban where a BoH can be found half of the time. Since you are in slashem, you can also obtain a Bag of Holding by upgrading a regular bag in a potion of gain level (50% chance) that can be obtained by alchemy (typically with enlightment+levitation).

Anyways, having a bag of holding is convenient but is not strictly necessary to finish the game. There is also the possibility to wish for a BoH using the garanteed wand of wishing in the Castle. Unless it was already in your lost BoH of course :-)

geantvert Re:Don't foget (186 comments)

Putting a BoH or a wand of cancellation inside another BoH can make that one explode but ... Magicbane? I do not think so.
Another possibility is that your BoH was stolen (by a nymph) or that you dropped it (in water or lava) by mistake.

A few years ago, one of my Nethack games went like that

Move toward the door
Move toward the door
"A trapdoor in the ceiling opens and a rock falls on your head!"

NetHack: Still One of the Greatest Games Ever Written

geantvert Very adictive but... (186 comments)

... the keys used to specify directions are a real pain on laptops without a keypad.
I can't imagine anyone using the vi shortcuts (k for up and, going clockwise, u l n j b h and y).
Using an external USB keypad is a possible solution but my experience with those devices is that they are unreliable and they behave strangely with Numlock.

Ubuntu Gets Container-Friendly "Snappy" Core

geantvert Re:This actually sounds pretty cool. (149 comments)

The article indicates that containers can be upgraded by sending only the modified files so upgrading a lib should not cost too much.
If their system is not too stupid then it will manage the container at the file level and will try to share identical files between packages.

That should not be too difficult using checksums and hard links. If they don't do that then the kernel won't be able to share files between applications and the whole system will use a lot more memory. Linux application are sharing libs but also some data files such as TTF fonts.

How Relevant is C in 2014?

geantvert Re:C is primordial (641 comments)

The malformed sentence in the middleshould of course be "See for exemple the Gobject API" and later "If you want to create compiler for a new langage today, it is far easier to generate C instead of ASM. "

How Relevant is C in 2014?

geantvert Re:C is primordial (641 comments)

Then he must be in his mid-40s because I fully agree with him.

C is almost ML because almost all features of the langage can be directly translated into a few assembly instructions. This is also one of the last languages that still provides full control over memory and pointers.

C can be OO. It does not provide OO features such as inheritence or dynamic casts but they are easy to emulate with structs and macros. See forIf you want to create compiler for a new langage today, it is far easier to generate C instead of ASM. exemple the Gobject API. This is clearly not the most elegant way to do OO but it works and it can be as efficient a true OO langage.

Mathematical Trick Helps Smash Record For the Largest Quantum Factorization

geantvert Re:So worst case still classically exponential, bu (62 comments)

In a regular factorization all bits except the 1st and the last are basically unpreditable (in the sense that they have no generic and well defined properties that could help predict their value) so the probability of the number of identical (or different) N pairs follows the same rules than flipping N coins. In practice the number will be around N/2 with a very strong probability.

For N=1000, see for instance the graph for 'output 1000d2-1000' in http://anydice.com/program/4d4...

The probability that you get something outside the range 450-550 is almost zero so any method based on the idea that some factorizations will have a lot or few identical pairs is unusable in practice.

18th Century Law Dredged Up To Force Decryption of Devices

geantvert Re:5th Admendment? (446 comments)

Indeed but as in many paradoxes, the problem is not in the answer but in the question.

Trying to answer a boolean problem (with true or false anser) specified using fuzzy properties is usually not possible.

Is that object hot?
Is that object blue?
Is that object big?
Is that object heavy?

Those questions are all ambiguous and they can all lead to (fake) paradoxes similar to the chicken and egg. For all of them the only sensible answer is: How do you define hot/blue/big/heavy?

A computer in an old movie would just say "Not enough data to compute"

18th Century Law Dredged Up To Force Decryption of Devices

geantvert Re:5th Admendment? (446 comments)

This is more complex than that. Look at that page

http://en.wikipedia.org/wiki/B...

According to your definition of a chicken:
  - common pheasants can breed with chicken and so are chicken
  - capercaillies can bread with common pheasants so capercaillies are also chicken
  - black grouses can bread with capercaillies so black grouses are also chicken
  etc

Of course, this page only mention known hybrids and a several more are likely possible and some may even occur naturally in the wild.

So at the end, with that definition, it is likely that a duck, a struthio, a penguin and most birds are also chicken.

18th Century Law Dredged Up To Force Decryption of Devices

geantvert Re:5th Admendment? (446 comments)

I see no paradox. The problem is just that chichen and heap of rice are not well defined concepts. We, humans, like to categorize thing using words but most of them are ambiguous. Give a proper definition of a chicken, something that can be tested non-ambiguously, and the chicken & egg paradox will disapear.

For example, we choose take a reference chicken, sample its DNA and specify that any living animal with less than 1% differences qualifies as a chicken. One of the (female) ancestors of our reference chicken would not qualify as a chicken. Since we are human, let name this animal a chickenausor. So that chickensausor laid a chickenausor egg from which came out a chicken (according to our definition). So the chickenausor came first, followed by the chickenausor egg, the chicken and finally the chicken egg.
