we have the concept of "airplane" mode. what's so hard about coding up a "driver" mode? oh wait... it's illegal to use a phone whilst driving, so "driver" mode would basically be synonymous with the "off" button.... :)

.... um, it's 2014, the linux kernel is a critical part of the planet's internet infrastructure, is used in TVs, routers and phones all over the world, and you're *seriously* telling me that its internals aren't fully parallelised? i thought the linux kernel was supposed to be a leading example of modern operating system design and engineering.

I'm sure the math can line up to make it "work" on paper but how exactly does one test such things?

You look for consequences of the theory. Things that would happen as a result of this, but which you won't expect otherwise.

A great example being the recent announcement by the BICEP2 people. The theory they were working on was inflation - which made the maths work on paper, but happened billions of years ago so was hard to test. But the theory predicted that inflation would have caused an "imprint" of gravitational waves in the microwave background radiation, something unlikely to happen otherwise - and these people were able to detect this imprint.

This is how science works sometimes. The theoretical physicists come up with a theory, the mathematicians prove it is possible and the experimental physicists find some consequence of the theory that can be tested.

this article explains in depth what the problem is. the SEC has now been alerted to the problem, and is investigating. the people who found the issue believed originally that this was deliberate, but it actually just turned out to be a systemic problem of the speed differentials between different routes that high-frequency trades come in at.

what they originally discovered was that they could see a price on a screen, but the moment that they put in the bid to a number of brokers, the price would DISAPPEAR. they thought that this was deliberate, that someone was scamming them: it turned out that this wasn't true, but it took a couple of years of investigation to find out. what they did was they put in *individual* bids *directly*, and found that they were accepted. they then investigated various combinations, introducing delays into the bids, and found, amazingly, that it was down to the *time of arrival at the exchange* of their bids as they were sent via numerous brokers.

so it was only when they invented a tool (which they called "Troy") that *deliberately* introduced networking delays, such that the bids would (as best they could manage) arrive within milliseconds of each other at the exchange, that they managed to trade successfully.

if however any one of those bids happened to go via a different ISP, or a different router, or any other random combination, then the bids would *FAIL*.

the problem it turns out is that these delay effects are well-known. most of the money in high-frequency trading is therefore made by seeing a slightly slower broker's prices, then putting in an undercutting bid *knowing full well* that the other broker has a slower network. and this aspect of high-frequency trading is what is currently under investigation by the SEC.

*this is why the introduction of networking delays is so absolutely important*.

the people who discovered this phenomenon basically had to set up their own independent exchange in order to solve the problem. they needed to introduce a delay of 350ms as a way to make things fair for everyone. they did this by basically putting in 38 miles of fibre-optic cable in a shoe-box in the basement of the server farm that they leased.

it turns out that once investors discovered this, they began *specifically demanding* that their trades *exclusively* be brokered through this new exchange that had this 350ms shoe-box delay. it actually caused a lot of embarrassment for a number of brokers and trading houses because the brokers were explicitly disobeying their client's instructions, because the brokers didn't understand how important this really is.

anyway: you really have to read that article (or the book) fully because it's quite complex, and it's basically an inherent flaw down to the fact that the internet (TCP/IP) is routed randomly, thus introducing gross unfairness that has become the subject of intense investigation, very recently.

so yes, *all* trading should be done with at least a 350ms delay.

Rosetta was licensed from Transitive, which was eventually bought by IBM. Apple didn't own it, so they couldn't open-source it.

I'm willing to bet that Classic drew on an ancient codebase with bits of licensed code mixed in. Getting it in a state where it could be open-sourced was probably more trouble than it was worth.

in the studies that i've been doing for the past four months the best explanation i've encountered is one where particles are actually photons obeying maxwell's equations *to the absolute* letter, on some form of circular (or knotted, or hubius helical) path, where the epicentre creates a synchtronic electro-magnetic field that it in symbiotic support of the epicentre. there is actually a lot of research recently into optics which shows that it *is* actually possible to create phased laser beams that will literally bend in a semi-circle.

with that description in mind, the definition of a "particle" is therefore that the phase of the photon at the centre rotates in one direction.... and that for an anti-particle it rotates in the opposite direction. the string theorists / knot physics people have this down as "the knot being tied left-handed or right-handed".

it's really that simple... but it requires a bit of explanation otherwise it makes no sense. why did the universe choose one in priority over the other? who knows: who cares. the choice has been made.

que?? since when did married people have sex??

ok. i understand. there are personal views and there is a naive belief that his personal views will somehow interfere with his legal obligation to enact the articles of incorporation as a Director of a Corporation. to imply that someone is unfit to distinguish between personal and professional (legal obligations) is actually a very very serious accusation to level at someone, for which he could probably demand significant compensation, as well as initiate libel lawsuits against those people making such defamatory remarks. as he has faithfully been the CTO as well as a loyal person within the Mozilla organisation for such a long time i think he would stand an extremely good chance of winning.

i have a bit of a problem comprehending firewall rules (and deploying them). i asked around (just as you did) and got the advice "use fwbuilder". i liked it so much that i ended up writing a python script that parsed its xml files and generated HTML output so that i could clearly see what it was doing.

but, despite admitting that i am not a firewall rules expert, i do have to say that nothing substitutes for actually studying what firewall rules are and understanding them properly. i say that from the position of being a person who, whenever they need firewall rules, does an internet search and cuts/pastes the results successfully into an amalgam that "does the job", but it "does the job" with the concern always being in the back of my mind that i probably completely messed it up...

i'm sorry but i genuinely fail to see the importance of any of this "personal view" stuff. a technically-competent person who has been with it almost since the beginning: they were the CEO of Mozilla for about a week. someone as technically competent as brendan should have absolutely no difficulty firewalling personal from professional: why do we have to have idiots believe otherwise? could someone therefore please explain to me in simple language what's really going on?

the effects of stress in exacerbating and causing physical ailments is one that is well understood. many people naively believe that genes are the sole exclusive means by which illness may occur, despite there being innumerable counter-examples clearly demonstrating that this is false. that does not prevent people from *believing* that genetics is the sole exclusive cause of one particular illness or another, and *for such people*, that belief, when they are presented with such "quotes truth quotes", is quite likely to result in their death, due, ironically, to stress *triggering* the very illness that is merely latent rather than active within their genes.

here on slashdot we have people who, by and large, are capable of logical and rational thought. when presented with scientific issues, they apply rational bullshit filters on the topic of for example genetics. many of the opinions marked "insightful" on this article are a clear demonstration of that. however the general population has little understanding of genetics, and many many people simply do not think "rationally".

on the whole then, if it became a *legal requirement* to *force* people to listen to a doctor telling them words which, when that person heard them, were translated in their own minds due to their lack of knowledge and self-belief, that "they were basically dead already because of their genes", i would consider such people who pushed such laws through as being severely mentally ill as well as their actions being morally reprehensible.

answer: no. it is highly irresponsible to force absolutely everyone to listen to something that they are not fully equipped to comprehend.

my biggest concern is that they start creating what can only be described as "generation time-bomb crops", in a pathologically-insane effort to further save money. "time-bomb crops" would be those which you plant once, they grow, seed, plant twice, they grow, place a third time and they FAIL.

now imagine such insanely-dangerous crops pollenating and cross-pollenating world-wide and it's not so hard to imagine a scenario in which world famine occurs within a five to eight year period in which all food crops world-wide completely fail.

i was actually pretty shocked when i first heard of sterile seeds that even have a *single* generation planting. there's no guarantee that nature will not, through its own process of DNA evolution, *accidentally* come up with generation time-bomb crops.

i've said it once and i'll say it again: genetic modifications to crops are so insanely dangerous that i'm beyond understanding why people do not understand this. if there was even the *slightest* risk of killing 7 billion people *why would you even contemplate it*?

It seems to be an increasingly common tactic for games developers to put out an advert-free game, wait for it to gain market share, then force an 'upgrade' that has no improvements at all, but is crammed with so many adverts that the game is barely playable. I deleted "4 words 1 picture" when it turned into "4 words, 1 picture, 1 full screen advert", but I would rather have kept the old, playable version on my phone.
