Re: I seem to recall reading this experimental procedure before
Indeed. One of the most important experiments in physics, although it routinely gets overlooked when documentaries are looking for the big moments in science.
It also sounds suspiciously like the gear used to look for gravitational waves. In fact, from the description I can't see how you'd tell the difference if you did detect something. Presumably there'll be a subtle signature in the signal that's below the noise level of journalists.
Re: I think...
There are lots of people who are scientists (but not climate scientists) who have plenty of relevant knowledge for assessing the work that climate scientists are doing. Many of them have extensive knowledge of data analysis, computer modelling, physics, chemistry, statistics and all manner of other subjects that are very relevant to climate study. Many also work in far stricter disciplines, where the scientific method and the burden of proof are adhered to far more closely than in climate science and where being a sceptic is seen as fulfilling a valuable scientific role.
Many people with these sorts of backgrounds look at what climate scientists are doing and feel they are letting science down, badly. They can see very little scientific rigour being applied and no scientific basis to the theories that predict future climate - principally because none has ever passed even the simplest of experimental tests. These details are important, because they are what distinguishes science from opinion.
So, to put it bluntly, there is every reason to think that the man-in-the-street's opinion will be just as accurate as that of the climate scientist, because neither is doing science.
Re: Booksellers do deserve protection
No matter how "good" they are, why would I go there to buy something they don't stock? Small places inevitably don't have as much stock. When buying books, the range available is quite important. That's why Amazon is a better solution, quite apart from the price.
Meh, it's all standard these days
Standard suitcases already contain most of the required sensors for this sort of work. They contain plastic parts that fracture at a pre-determined impact to detect rough handling. They have bendable metal handles that detect excessive loads (just check to see whether the handle will still pull out when it arrives). They also have absorbent coverings to detect moisture and many will reveal contact with abrasive or sharp objects by ripping.
Of course, you can also install your own sensors internally; a cheap bottle of wine will reveal if the bag has been thrown around by imparting a red stain to your undergarments.
Re: different terminology please
Technically, I think he has stopped. Unless he uses it again, of course. But you won't know that until he does, so it's too early to complain yet.
Re: To put 300 times the speed of sound
Actually, that they're orbiting at 300 times the speed of sound is about the least extraordinary thing about them. In astronomical terms, that's a boring, pedestrian speed.

This is an insulting first step towards failing to rebuild trust in our transatlantic relations.
Re: Like it's a good thing?
Yes, definitely a bit vampire squidish, that.
Re: So in summary...
"If they accede to demands without sending them to court, Google are pro censorship, and their previous freedom posturing is exposed as lies!
And if Google send things to the courts, then Google are arrogantly attempting to defy their obligations under EU law!"
But that's pretty much the dilemma we all face, including the law itself. Either we're in favour of censorship or we're in favour of violating privacy. Unless we all agree on exactly where the dividing line falls (and there's not much chance of that as it's a political judgement as much as anything) then there's no squaring this particular circle.
The usual solution in such cases is to enact some fairly vague and ambiguous laws so that only those people who care enough to spend a fortune going to court ever need a firm decision. The rest of us just have to lump it because we can't afford the money or effort to fight. In the case of data protection, you also set up a watchdog with no teeth to take the wind out of people's sails if they have the cheek to complain
Looks like we're fairly well down that path already.
This is academia
I guess they were just miffed he didn't get any publications out of it.
Re: I'm against it at this time. here's why...
One big difference between the US and UK is that we drive on the left in the UK. But I guess we should be OK there, so long as NASA don't get involved.

Re: The underlying problem is...
You're right. Browsers are already too complex - a bit like operating systems became, in fact. I think it's time we stopped using "a browser" and had browser distributions like we have Linux distros. That way, projects could more easily set up new forks of (say) Firefox and just use the bits they like.
More importantly, they could also add in any extras they want and could enhance neglected areas (like security and privacy) without taking on the massive challenge of supporting an entire browser. At one time, Firefox's extension mechanism was a great strength, but many extensions now look like little more than sticking plaster and just provide an excuse for not tackling fundamental browser problems.
We need to develop an ecosystem where competition can help drive forward the individual component parts of a modern browser and take control out of the hands of the big players.
Or that you can use a ruler to measure any length so long as it's not 10cm.
I doubt they can do that. Amazon has probably already patented the idea: "Method and Apparatus for issuing daft patents...".
Re: One good thing Microsoft has embraced and extended
"Dont need link scanning, email scanning, network lock downs, child monitoring, arbitrary trusted app levels, convoluted firewall blah blah blah..."
You need to tell that to pretty well everyone who's writing stuff these days. No-one seems happy any more with software that does what it needs and nothing more. If another feature is possible, then it needs to be added... and on and on... until it collapses under its own bloat. AV, unfortunately, is not alone in this by a long way.
That's not to say it doesn't deserve to die, though.
...should cost more if you're wearing big glasses.
Grub's a really touchy beast these days
Especially if you've more than one OS installed. Breaks as soon as you look at it. Fortunately fixing it is usually pretty simple. Overall, not necessarily a good situation, though.
I guess it's just become over-bloated as these things always seem to do.
Re: The real bug
No, the real bug is having a software development system that allows someone with insufficient experience to add code to a system that needs to be secure - and then not having a sufficiently robust review process in place - and then installing that software in a critical situation on huge numbers of servers around the world.
This bug is the sort of mistake beginners make (I believe the culprit was still at uni). I'd be embarrassed if I put a bug like that into a one-off throw-away lash-up. But somehow it got into openSSL which everyone regarded as secure.
It's a bit like the debt-laundering that took place before the financial crash. Everyone thought the debt was solid, but simply because no-one bothered to look at the fundamentals. I think this incident has shown FOSS security to be based on similar principles.
In my view seeing a naked memcpy call at all in supposedly secure code is like walking into a restaurant kitchen and seeing a big pile of rotting carrion on the floor. The staff may know not to handle it before dipping their fingers in the gravy, but it's a clear danger that you don't want to have around. It may cost to clear it up, but that's what you have to do.
memcpy is a big red flashing warning light that says "make damn sure you've checked and sanitised every bit of data that goes in and out of here" (not only memcpy, of course, but quite a few other C functions). In fact. I'd suspect simply looking for all the memcpy et al. calls is a pretty good way of finding vulnerabilities. The best approach is to wrap them up pretty tightly. Even that's not 100% secure, but it does make a difference and in security code it's 100% worth doing.
Re: I don't get it.
That makes me scratch my head a bit too. Either it's a lot faster than a classical computer or it doesn't really matter whether it's a quantum computer or not.
I could say I'd sold my soul to the devil in return for the skills to make blisteringly fast computers, but if the computers I sold weren't actually fast, what would be the point?

What bit of "trust" don't they understand?
OK, so you have to edit a config file. Not ideal, obviously.
But OTOH, do you want a dancing paperclip popping up saying "I see you're looking at a web page, would you like me to help you create a short cut to that?" and then proceeding to create a widget that plays a tune every time you mouse over it, tells you the time of day in the web site's locale, adds it to a semantic map of your browsing habits, emails all your friends to tell them what a great site you think it is and posts to Facebook, Twitter et al. just for good measure, before suggesting where you can get discount vouchers, signing you up to the web site's spamletter and prompting you to create an account?
There's a balance to be struck here. In my view it's about at the level of right-click and select "create a desktop link to a web page". Unfortunately, 99% of GUI designers seem to have convinced themselves we prefer the "paperclip" approach. So kudos to Gnome for going the other way, but it's still not right guys!!
Now that's proper mental mental arithmetic... a counting system with multiple fields and different bases in each field. Who on earth would invent a system like that? Oh, hang on... I seem to recall spending several years of my life practicing that stuff.
FWIW I also recall we had a computer* made out of relays when I was at school that could do arithmetic in yards, feet and inches and suchlike. I think it could calculate pi as well, but rather slowly.
* IT angle.
I feel a patent coming on...
Rounded corners aren't cool in monkey society. Simians prefer curved, elongated shapes with pointy ends. So that idea's now in the public domain, before Apple patent it and come up with the iBanana.
Re: You can get the fakes at clubs
I think it doesn't really help that they change the design on coins and banknotes so often. There are so many designs in circulation now that I don't necessarily recognise them all and I'm not that surprised when I see a new one. If I got given a pound coin with a picture of Mickey Mouse on one side, I'd probably assume it's some stupid attempt to commemorate Walt Disney or something.
So now I suspect the fraudsters could start minting 13-sided pound coins and still get away with it. People would just assume it's a new official design.
You seem to be talking about theories that propose that outside our universe there are other things (that might be other universes), hence a multiverse. But in "quantum physics" (as mentioned in the title), the multiverse normally refers to the idea that all possible quantum statistical outcomes of an event actually exist together (rather than one of them being special and representing a unique reality).
So have you just conflated two rather unrelated ideas, or is there some more subtle connection between the two that I've missed? For example, is it being suggested that the existence of inflation is somehow the cause of quantum uncertainty?
You call this a triumph for Einstein?
The cosmic gravitational background radiation is enough to make Einstein turn in his grave - although only very slightly.
Re: Is there an Arapaho word for this?
While attempting to put up a fence the other day I was mystified by where my hammer had gone. It was there the previous day. All the other tools were still there, but the hammer (a vital tool, obviously) was nowhere to be seen. Now I'm well aware of the behaviour of tools, so I naturally assumed it would turn up when I picked up the spirit level, or turned over the concrete-mixing tub, or whatever. But no, there was no hammer to be found anywhere. So the day passed with little fence-putting-up being done in between searches for the hammer and much cursing.
Come 5pm, and the wife returns home and sneaks into the garage clutching a hammer. "I hope you didn't need this today, I just borrowed it to put up a picture at work... ". There is no Arapaho for my thoughts at that point.
It's an interesting sleight of hand. On a desktop with no Android-like permissions, any program that started reading data it hadn't written and calling home with it would be called spyware and the antibodies in your AV/security suite would be out to kill it.
OTOH, by including permission settings on mobile devices, it comes to be assumed that if an app has a permission then it's justified in using it, even if it didn't actually need it. So adding something that apparently enhances privacy and security actually ends up reducing it. You'd almost think that was a deliberate move unless you knew better ;-)

In my case opting out of junk mail has had ZERO effect on the junk mail, but has nevertheless successfully opted me out of NHS circulars, or so it would appear.

Re: The BBC tells us what's really happening
The point I was making is that a scientist shouldn't tell you what the evidence is going to show when they've just said they don't have that evidence. They should wait until they have the evidence, then see what it indicates. At least, that's the way I was taught to do science.
But I think it nicely illustrates the do-you-or-don't-you dilemma between attributing unusual weather events to climate change. Beneath every supposedly objective scientist there's a political animal that wants a certain outcome and wants to make that link, as sneaked out here. I'm not saying it doesn't happen on both sides, as it clearly does.
The BBC tells us what's really happening
Here's what the BBC had to report recently from a "climate expert" (Prof Jennifer Francis) on the subject of whether the jet stream is changing:
"Our data to look at this effect is very short and so it is hard to get a very clear signal.
"But as we have more data I do think we will start to see the influence of climate change."
Spot any science here? Yes, it's in the first statement and it says "there is no scientific basis on which to make a claim about climate change". Then she makes that claim about climate change that she has just told us has no scientific basis.
So even the experts don't know what to make of it, but they sure know what they'd LIKE to make of it!
Re: Yes indeedy
My understanding is that you can't pick any old pattern. It has to be every number, or every second number, or every third, etc. But that's just from Wikipedia.

Tough. I'm allergic to the stuff, so it'll have to be banned I'm afraid!
Continuous ink supply systems...
...are good things to have if you've a little technical skill to set them up, so it's worth seeking out a printer that'll take one. I'm currently using a Canon MG5250 with a CISS and ink is now effectively so cheap I don't have to worry how much I print.
The downside is the cost of the CISS (about £50 when I bought it) and the fact you'll need a new one if you change printers. So I'm planning on getting an identical printer as a spare.
Re: Somebody put it far better than I could...
You just need to remember that he's more interested in facts being interesting than in being correct.
Re: Who cares who is first to photograph?
I always thought the IAU (www.iau.org) was the arbiter of astronomical discoveries. As the article mentions a "telegram" (remember those?) I assumed this was the official announcement because telegrams used to be the way it was done. Maybe it still is.
However, I couldn't see anything obvious about it on the IAU website.

Re: "Lawfully collected"???
It may be legal in the US for the NSA to snoop on Brits. But who made it legal in the UK for a foreign power (the US) to snoop on us without a warrant issued in the UK (and the same applies to every other non-US country)?
It seems to me that if the NSA has taps into infrastructure in UK territory, then they are breaking UK law. In that case, the likes of GCHQ should be involved in searching out these taps and turning them off. After all, who do GCHQ work for, us or the NSA?
Much the same should be happening in all other countries as well.
Even if found guilty...
I'd rather have the courts decide what punishment to set. If they decide the miscreant needs to be named and shamed on Twitter, then by all means let the police do it in the name of the court.
But otherwise, this is the police deciding what punishment should be applied and that's not a good direction to be heading in. Before I'd be happy with that, I'd want to see this overwhelming public support translate itself into legislation that authorised the police action.
Even then, I'd want people to have the option of accepting it as a punishment (although obviously it'd be a pretty weak one on its own) or going to court to challenge it - much like on-the-spot fines.
Practice makes perfect
Anyone who plays a musical instrument will know there is an analogous musical problem. Some musical phrases can be especially hard to play for some reason - maybe because the moves are awkward or maybe because they're just unlike anything else you've played before.
Anyway, you can't just label them hard and not play them. The solution is practice. Play them over and over as slowly as you need and eventually you'll find they come naturally. It can sometimes take a while, though.
The same is true of tongue-twisters. Repeat them over and over sufficiently slowly to get them right each time and after a few days (on and off) you'll find they become quite easy. Try it...
And I suppose...
...this is "all within the law" (TM).
So did the UK government know the US was hacking our computers on a grand scale? If so, under what UK laws did they allow it to continue and was GCHQ involved? If they didn't know, then why not?
But wine is commonly brewed today in tanks that are basically like covered swimming pools, dug into the ground and lined to make them watertight. I dare say the ancients could have mastered that technology.
