OK, well, why the hell do they owe you an explanation of what they spend it on? I think the code they produce pretty much speaks for itself, don't you?

Dealing with infringements is expensive, too. They sued Cisco, as I recall. Others, too. Lawyers cost money.

I'm not particularly sanguine about the idea of importing the anal-retentive beancounter caste into libre project management, frankly.

mctaylor (3856347) writes "The Free Software Foundation issued a rambling and evasive response to inquiries into the Shellshock bug reported here previously. In response to inquiries, the Free Software Foundation reasserts the superiority of free software over proprietary solutions, but notes:

Free software cannot guarantee your security, and in certain situations may appear less secure on specific vectors than some proprietary programs

, and concludes by stating:

the solution is to put energy and resources into auditing and improving free programs.

. But shouldn't the GNU project have been doing that already? If it is not, or can not, then perhaps we should be asking ourselves where our donations have been going. What are your thoughts? Is the FSF really spending our donations wisely?"

+ - Apple Yet to Push Patch for "Shellshock" Bug

Submitted by Anonymous Coward
An anonymous reader writes "Open source operating systems vulnerable to the Shellshock bug have already pushed two patches to fix the vulnerability, but Apple has yet to issue one for Mac OS X. Ars Technica speculates that licensing issues may be giving Apple pause: "[T]he current [bash] version is released under the GNU Public License version 3 (GPLv3). Apple has avoided bundling GPLv3-licensed software because of its stricter license terms....Apple executives may feel they have to have their own developers make modifications to the bash code.""

+ - New Patch for "Shellshock" Bug Issued Thursday

Submitted by Anonymous Coward
An anonymous reader writes "A new patch was released Thursday for the "Shellshock" bug in the GNU Bourne Again Shell (bash). The initial patch, issued on Wednesday by the GNU bash code maintainer Chet Ramey, was found to be incomplete by Tavis Ormandy, an information security engineer at Google. Ramey wrote a new patch Wednesday night and tested and packaged it Thursday. Various Linux distributions pushed out the patch very late Thursday night."

+ - Government employees and politicians gets special status from TSA->

Submitted by schwit1
schwit1 (797399) writes "Government employees and politicians get preferential treatment from the Transportation Security Administration simply for being government employees and politicians.

Meanwhile, everyone else is stuck in an “aviation security caste system” based on dozens of watchlists compiled by the TSA, FBI and other law enforcement agencies, along with a secret formula the TSA believes can sort passengers based on hypothetical analyses and conjecture.

That’s the conclusion drawn by Hugh Handeyside, a staff attorney for the ACLU, who reviewed a recent audit of the TSA, every traveler’s favorite government pseudo-police force.

The TSA doesn’t really have a handle on how many people end up boarding airplanes despite being on the so-called “no fly list.” The TSA uses literally dozens of different lists provided by federal law enforcement agencies to determine which travelers should be singled out for extra screening or should not be allowed to fly, no matter how much screening they receive.

But the keen legal minds at the ACLU caught another serious problem — keeping all those separate lists — and “blacklisting” some people while “whitelisting” others — is probably unconstitutional and is “stretching the concept of watchlisting to the breaking point.”

“Not only has the Transportation Security Administration expanded its use of blacklists for security screening to identify passengers who may be “unknown threats,” but it also has compiled vast whitelists of individuals — including members of Congress, federal judges, and millions of Department of Defense personnel — who are automatically eligible for expedited screening at airports,” Handeyside wrote. “These changes have made a broken watchlisting system even more arbitrary, unfair, and discriminatory.”"

"Tracking the RNG" would help you win the game, but it doesn't tell you anything about how to play the game.

That would be my point.

This AI learns to play the game, it then wins the game using experience it gains in the same way a human does - feedback from the game score.

That is one possible interpretation, which is not supported by the statements so far. That is not to say that it is not the case, only that it is not currently supported by what I have seen so far; something along the lines of "We tested this against games with multiple RNGs with no perceptible change in AI performance" would support that interpretation. There are other interpretations. People are *assuming* that "wins" = "plays the game" - and the company that did it isn't relieving anybody of that perception (understandably). That's the point. Exploration of other explanations for success are warranted.

Consider that, for games which possess a weak RNG (i.e. predictable starting conditions and knowable changes in game play, i.e. most old console games), it is in theory possible to play *blind* - in other words, not actually paying attention to what's going on on the screen, but simply hitting buttons at precise enough intervals. If 'score' is taken as a proxy for 'how far you can get in the game' (ceteris paribus, someone with a higher score made it longer), then most known machine-learning methods will converge on that/those sequence(s) without any understanding of 'the game' per se. It may even be possible to do that for short gameplay sequences based on pattern matches to known game conditions. While that does get off into the semantic weeds of what 'playing the game' is, it is difficult to differentiate between an AI which has 'learned' to play the game in the sense that it understands abstract rules, interprets game state, and makes decisions about what to do based on that observed state, and a neural network which has converged on the correct list of keystrokes to pwn the computer given certain observed starting conditions. One of them is impressive; the other one isn't, quite so much.

I find myself wondering about the following question:

How did they differentiate "learning to play the game" from "learning how to track the game's RNG"?

Most video games have ridiculously simplistic PRNG generators embedded in them. An AI might get "sidetracked" and learn how to play the underlying RNG output of the game, rather than the game itself. That would yield really good results for most arcade games of this type, I imagine (weak RNG, limited input and timing options, etc.) I don't know if they checked for that possibility.

Easy way to check, though: Reach into the game and substitute a better RNG (cryptographically-strong/hardware/quantum) RNG for the one in the game. That would enable you to quickly determine the difference. If the AI's game performance suddenly goes to shit, it wasn't a real game-playing AI. If it doesn't, well, all hail Skynet, I guess.

"... We wrapped a robot in a dead sparrow and decided to see if we could fool the other sparrows into interacting with our creepy, ghoulish automaton! It's *science*!"

And of course, it was COMPLETELY UNEXPECTED that the grisly abomination stapled to a tree branch triggered aggressive reactions from the other sparrows. Because every living thing JUST LOVES to be confronted with a soulless golem wrapped in the dead flesh of another of its kind. And that never causes pants-shitting terror or anything.

I can see it now:

Sparrow 1: "OH MY GOD! IS THAT... *THING* ... WEARING FRANK'S FACE? IS IT?! FRANK??!?!"
Sparrow 2: "It's not him anymore. IT'S! ...NOT! ...HIM! IT'S A MACHINE! Help me destroy it! Be his egg-layer one last time!"
Sparrow 1: "*snf* OK... OK... oh God, Frank... God help me..."

Yup. Science.

Is there, like, a review board or anything? Maybe that could screen some horror flicks before writing checks for this kind of bullshit? "New rule: If your study is substantially similar to the plot of any one of this library of 100 horror movies, or if it has a plausible chance of producing similar outcomes, we're not going to fund it."

Vital papers will demonstrate their vitality by spontaneously moving from where you left them to where you can't find them.
