Except none of your points applies to climate change.

The effect is robust: there was a whole independent project to determine if the thermodynamically meaningless "global average temperature" is increasing. It is: http://www.bbc.com/news/scienc...

The threshold of measurement is around 0.5 C for a single station, and we have an effect that is about 1 C over the past 100 years. Not as big a margin as one would like, but difficult to ignore. And growing.

No one has produced any results that show the instrumental temperature record in the past century is not real. There are debates about causes, but the reality of the phenomenon is not in doubt.

Everyone who has looked at the question agrees that there is about a 1.6 W/m**2 addition to the Earth's heat budget from anthropogenic CO2, so clearly when taking the "positive cases" there is still good agreement.

There are large and legitimate areas of disagreement with regard to climate change (far more than the moron, anti-science, "the science is settled crowd" would have you believe) but the basic phenomenon, unlike the EMDrive, is not just consistent with but actually required by the laws of physics.

Finally: the summary is terrible, even by /. standards. The article does not point out any errors in the experiments. Rather it points out that reporters have been lying about the experiments, pure and simple. That is not the fault of the scientists, who honestly reported their null results.

More frequently than you might think.

I highly recommend Lisa Randall's "Warped Passages" as a fairly recent meditation from a working physicist on the strengths and weaknesses of multi-dimensional theories, as well as some of the background on what motivates them.

The short story is that higher dimensions make it easier to generate universes like ours, which are almost flat gravitationally and have this ridiculous difference in scale between gravity and everything else. Regular 3+1 dimension Standard Model physics requires a ridiculous level of fine-tuning for this to happen, so it is interesting to look for deeper theories where these features arise naturally.

The problem with String Theories in particular--and as other posters have pointed out it really is a family of theories--is that they are almost useless for "model building", which is the activity of generating simplifications we can actually calculate with to describe the world as it is today vs the world as it was a few Planck times after the Big Bang.

So while string theory is neither "untestable in principle" nor "designed to resist testing" it is "naturally test-resistant." Some simpler variants--including a rather elegant heuristic model that Randall herself co-created--have been killed off by the LHC, but the diversity of possible low-energy models enabled by String Theory is so large and heterogeneous that in practical terms they cannot all be falsified.

In the meantime, String Theories continue to take up an inordinate amount of theoretical physicist's time and effort, and there have been fairly senior voices raised in concern about this, particularly because it has been going on for so long that we may end up with a generation of theorists who have never done anything but string theory and have come to the conclusion that it won't work.

Rather than waiting for this Big Reset, it would be nice if we started spending more time looking at non-stringy alternatives.

So in your view von Braun was an amoral, self-agrandizing liar who was willing to actively engage in the selection of slave labour working in death camps to build rockets that killed thousands of strangers just so he could play with cool toys? Because that's what you're describing.

I say "self-agrandizing" because everything that von Braun wanted to do would have been done without him, without the 12000 dead slave labourers, without the 9000 dead British civilians.

I've had some pretty extreme scientific and technical ambitions in my time, but have somehow been able to realize many of them without killing people, and have given up the rest because: killing people. So I'm willing to pass judgment on von Braun in this respect: if he faced a choice between following his dreams and not killing people I'd have to say the latter is the far better choice.

Even in those cases where you get a good service provider (which will depend on the specific people you've got working on your project much more than the company they work for, so anyone who says "Oracle = good" is missing the point) you still run into one of the most fundamental human problems: we suck at communication.

When you outsource something the degree of clear, concise, validated communication required is many times what is required for in-house development (where communication can still be a major problem). Capturing user needs and implementing them in a useful and user-efficient manner is hard enough with a high-bandwidth internal-communications channel. With outsourcing it is almost impossible for the people designing and building the system to get the information they need from the end-users.

So one question I would ask the OP is: how often do your provider's developers talk to your end users? (not your end user's managers, who don't have a clue what the system requirements actually are). If the answer is "never or hardly ever" then in-house is definitely the way to go, because your in-house team will have at least some chance of building a system that will serve end-user needs.

Which large reptiles are those? And which dinosaurs are they descended from? And how did dinosaurs, which were all killed at the KT boundary, manage to have descendents?

Dinosaurs are reptiles with their legs under their bodies. This makes them distinct from other reptiles (the kinds we have today, which are not descended from dinosaurs) which have their legs off to the side.

Mammals also managed the legs-under-the-body trick, and birds (which are descended from dinosaurs, unlike all modern reptiles, none of which are descended from dinosaurs, what with dinosaurs all being extinct without issue at the KT boundary.)

Most of which is not done by the surgeon. I've worked a lot with surgeons, and can assure you they are used to having other people do almost everything but surgery for them.

Surgeons are the equivalent of the "master programmer" team, which is a now mostly-obsolete team structure where there is one (or a very small number) of expert coders surrounded by a larger group of admin/build/whatever types who make sure the master programmer has nothing to do but code. It works on certain problems, but unlike surgery, the scope of what we expect software developers to do has grown far beyond what one person can handle in almost all interesting cases (I say this as a team of one who does everything from firmware to UI, but it is on a very narrowly defined embedded application that I've worked extremely hard to keep more-or-less within scope for a single very senior person.)

First off, what we can or cannot imagine has absolutely nothing to do with what is or is not real, so it isn't clear why you're bringing this up. Three hundred years of knowing what is real through publicly testing ideas by systematic observation, controlled experiment and Bayesian inference had demonstrated that the pre-scientific "method" of "imagining what might be the case and then reasoning from it" is a hiding to nowhere, knowledge-wise.

That said, as it happens I can imagine such an alternative history. One simple way of doing it is to have an intelligent species that evolved somewhat more quickly than we did on a planet formed in very short order after the supernova that birthed it exploded. Such a planet would have a good deal more 235U in the mix, making light-water moderated natural uranium nuclear reactors possible (of the kind that existed on Earth in at least one location 2 billion years ago).

An intelligent species on such a planet would likely never go down the hydro-carbon-fuels path, but would be all-nuclear, all-the-time from a very early stage of technological development (one presumes that in such an environment they would be evolved for somewhat higher radiation-tolerance than most terrestrial species.) As such, no hydrocarbon pollution would be evident.

Now, to be clear, I am not saying any of this is true. Merely that I can imagine it. There are quite possibly any number of subtle issues that make such a scenario impossible, and the failure of philosophy (knowing by imaging) tells us that we will be very hard-pressed to find them. But you asked for an imagining, and there one is.

Amen, brother.

(And don't forget the French!)

I think you forgot "FCUK NSA" somewhere in that NSA food... Or is it "FSCK GCHQ''?

Anything that has a USB port, really.

Essentially, anything that is run by NGOs or individuals.

Sure, in a corporate or governmental/military environment, USB ports are usually a big ''no no'' but some of use like them USB gadgets.

(Yes, before anyone ask, there has been infiltration through contaminated USB drives and keys ''abandoned'' in strategic locations...)

No, not extortion against Tails - extortion of money from the NSA or whoever else their ''clients'' are.

I am sure a lot of TLAs right now are salivating -- unless they have discovered these vulnerabilities before Exodus. In which case, silence can be golden, indeed.

Good for you. Not everyone can afford an hardware PRNG, though, so software it is for most of us.

Precisely - which is why PIDs are randomized on OpenBSD since... well, a long long time.

Try "ps -auxwww" on, say, Mac OS X and OpenBSD and the difference is truly evident.

Citation needed. Seriously, this is /. where everyone is a world-class programmer (except me, of course).

I will grant you that one.

Bzzzzt! Sorry, you lose. As I have already said, this is not a LibreSSL problem - it's a Linux PRNG problem. Unless I am mistaken, the same issue is non-existent under OpenBSD, because it's PRNG is different from Linux, better seeded and because PIDs are randomized under that OS.

You contradict yourself: if programming PRNGs is, let's say, a medium difficulty task (neither trivial nor too hard), how come you have spent years designing and programnming PRNGs (your words, not mine) and how come the world is full of bad bad bad PRNGs? Surely, by now, everyone would have agreed on a reasonable implementation?

The truth is, PRNGs are HARD to program, because computers are not good at generating truly random numbers. Period. The best implementations all rely on some form of hardware generator. But don't take my word for it, go ahead and read this instead.

As opposed to the magnificent job OpenSSL has done all these years, with information leakage, bug reports that went uncorrected for years and accumulated cruft for such modern OS as VMS, DOS and Windows 3.1?

I think you need to tone down the hysteria a notch right here.

For different values of "tactful", of course... ;-)
