Submission + - Leak Reveals Government Conspiracy, Atrocity 1

Sigmon writes: An unauthorized wave recently broadcast on the Cortex has revealed not only the existence of a previously unknown settlement on a far away border world called Miranda but also that the entire population of settlers was inadvertently wiped out by a top-secret Alliance program. Miranda was purportedly used as a testing ground for G-23 Paxilon Hydrochlorate, or simply "Pax" — a chemical agent designed to calm the population and weed out aggression. It seems the test did not go as planned. Also, reporters have been dispatched to the location of a battle not far from Miranda's location where the Alliance fleet has apparently suffered significant losses. It is unknown if the two events are related at this time. When contacted for comment on these events, government officials were very tight-lipped, however one official responded with a confusing statement about "Damming a river."

Isn't this complaint similar to someone in the 1800's complaining about how the big industrial machines make it so that hobbyists who craft a small engine in their barn are no longer competitive, or in the mid 1900's complaining about electrical technology, or the 1980's complaining about circuitry, or ten years ago you couldn't build a competitive laptop? We have been in a golden age of hobbyist software since the personal computer allowed large numbers of people to own computers at home, but maybe that technology has run its course.

But there will always be "hackers" - the tools and technology will be different, but that's ok. In 20 years I bet people will be complaining about something new, like how the makerbot 24.5 is so locked down it's hardly worth using, but hey, look at my cool new dna sequencing kit! I can clone a small dinosaur!

Comment Get a laptop and a desktop (Score 3, Insightful) 385

For serious data analysis and development a laptop isn't the right tool. You want a really good keyboard and a large display (or 2) so get a desktop. For general data analysis you will still want a pretty beefy workstation (e.g. >16Gb memory) and to get those specs in a laptop gets pretty expensive. For heavy duty work she is going to ssh or vnc to a big server/cluster and she will really appreciate the extra real estate on the display(s).

She can get any laptop for general email, web surfing, etc while out and about (or maybe a tablet?). But it is much easier to query huge amounts of data or write serious code at a nice desk setup in her room (or office if she gets one).

The problem with that study is that it focuses on the HPV vaccine, where the conservative based objections revolve around the believe that giving the vaccine is akin to tacit approval of teenage sex (not dissimilar to the conservative objection to safe sex campaigns).

It is not an anti-science view, in that they believe that the vaccine does, in fact, prevent HPV transmission, and they do not believe in totally debunked theories such as the MMR/autism link. It does not appear that the survey attempted to break out the resistance to, say the MMR vaccine, which is clearly based on junk/psuedo science stoked by the Lancet article, versus Guardacil, where the resistance is based on moral objections.

I think one of the biggest problems that our modern democracies face is the confusion between science and morality. These are orthogonal bases but more and more they are being conflated into a single dimension where pro-science == moral and anti-science == immoral. There are lots of people who are anti-evolution, anti-climate change, yet perfectly good and decent people, and there are lots of people who are big supporters of all fields of scientific endeavors who are complete a$$holes. And they both have things to say, and in a democracy, get to have a voice in our joint decisionmaking process called politics. To paraphrase Churchill, it sucks but it's better than the alternative.

The whole point of Duchamp's Fountain is that it forces the observer to ask the question "What is art?" Can something be art despite the fact that the object itself has no artistic merit at all, and only could be art as a result of being in an art show? Which satisfies the definition of art, the object's artistic merit, or the opinion of the community (of artists and museum curators and patrons)?

I think you are confusing yourself by overthinking things. A 20% exponential growth function doesn't have a slope of 1.2x, it has a slope of ln(1.2)*exp(ln(1.2)*x). But if you miswrote and didn't mean to use the word "slope" and just meant "Y" then actually Y=X^2 is a closer way of thinking about exponential growth than Y=1.2X. I'm assuming your background is computer science, so think of big O notation. If someone mistook O(exp(n)) for O(n^2) you would think they were overly simplifying but for small n it probably not too bad. But if the mistook O(exp(n)) for O(n) (linear) then you would know they are totally off the mark. In the same way, mistaking an exponential for a quadratic is a silly, stupid error, but mistaking it for a linear function is really wrong

The process that gives you that fish size is in fact an exponential process, so in your example, fish size grows exponentially. It is because you say "bigger each year", which implies the recursive relationship S(t+1) = 1.2 * S(t) where S(t) is the size of the fish caught in year t. So if you catch a 1 pound fish in year 0, then you catch a 1.2 pound fish in year 1, and a 1.44 pound in year 2, a 1.728 pound in year 3, etc. S(t+1) = 1.2 * S(t) can in fact be represented as the exponential growth model S(t) = S0 * exp(lambda * t), but that is an exercise left to the reader.

It's not trickery, it's just a label for the particular math used to model the process. And if a process satisfies that model then there is nothing wrong with using that term. But if you are pointing something else out then please reply.

If

Rx = revenue in year x
R0 = revenue in base year (year 0)
then 20% growth means: Rx = R0 * (1 + .2)^x

represented as:

Rx = R0 * exp[(log(base e)(1 + .2)) * x]

Which is exponential growth as seen at Wolfram where lambda = log(base e)(1.2) (and every mathematician I have ever known). Not sure what you mean when you say exponential growth, but it's not the mathematical definition.

Your soap box is quite misinformed.

A depression is a TERRIBLE time to own any asset. You can move to follow a job if you own a house by simply selling your house. You will probably do so at a loss during a depression, but if you were renting you wouldn't get any money out when you move either. And if you were renting, and saving money on the side, whatever you invested in would also have also gone down because *it's a depression*.

No of course not. They only keep a prorated part of their contributions to reflect the work that they have actually done and pass the bulk of it to the original writers of the code (or Canonical, the Linux Foundation, or FSF to the extent that they can't track down the original authors). It says right there in the blog posting...

Hmmm it's there somewhere...they say

"We believe that if we want to see the world of open source software grow and compete at the same level as closed source software, we should encourage users to pay for its development;"

so I'm sure they are doing their part to pay for its development.
