AFAIK, most (perhaps all?, I can't think of an exception) states are still 0.08%, although more and more have reduced limits for new/underage drivers. There are some groups pushing to lower this to 0.05% or even lower, though. Which IMO becomes a problem. I don't condone drunk driving, but lets not lower the limit to the point where a single beer or glass of wine with a meal will put you over.
ISPs will have to foot part (probably the largest part) of the bill because of "campaign contributions", or whatever the correct term for legal bribery is Down Under.
Peered file sharing will work fine for the parts that are common to everyone, like background images, javascript libraries, CSS, etc. Actual user specific data and operations, like bank account balances, I can't really picture going through hosts other than the customer and the bank, but that's probably a miniscule fraction of the data transferred.
That sounds sort of like I'd expect something of this sort to work, but there has to be more to it. All of those things mentioned as "common to everyone", with the possibility of some larger JS libraries or Java applets, are already fairly small (or at least can be, anyone using a 4+ MB image for their background should be summarily executed). I'd expect the overhead of noting the request, sending the torrent data, then having the local browser connect to multiple peers would actually INCREASE the total amount of bandwidth consumed.
Now, something like this makes some sense if links to download large images, videos, game updates, or whatnot point to a torrent instead of a large, locally hosted file, but in that case, I don't see how a "torrent-based browser" is any better than a stock browser with a built-in BT client.
OK, I'll take your word for it as I have zero knowledge of K-Mart Australia. I had (apparently wrongly) read your reply to the AC parent to mean K-Mart US and Sears were two different companies.
It could be worse...the first grade newsletters that get sent home from my daughter's school are.pptx (seriously). I think I've only seen Comic Sans once or twice so far, though.
Or, they could limit the speed of their connections somewhat, or give you a choice of speed vs. cap. For example, unlimited data but speed capped at 1 Mb/s (or even 500 kb/s) vs. 5 GB/month data cap at max speed. The former would be more than adequate for most of us who aren't streaming 1080p or 4k video via wireless plan.
...but I think most would agree both are more important than a bloody football field that primarily benefits a small percentage of the student population.
You most obviously have NOT lived in the deep south or the midwest. Can't afford new books, but we can build a $2M football stadium for the high school and hire 5 football coaches. Because "Johnny gonna be a football star".
Out of curiosity, what journals are you submitting to that require "camera ready" copy? I'm aware of very few in the life or physical sciences, and most of those aren't exactly top tier.
Most journals expect the text (including citations) in a "standard" format, I'm aware of none that won't accept any semi-recent version of word (.doc/.docx), most accept PDF, many will accept RTF, a few will accept TEX (maybe most if your field is physics or math). They generally want each figure as a separate file, either vector or bitmap with a fairly high minimum resolution, so they can resize the images and reflow text around them. How tables are presented/accepted is pretty journal specific, but this is the one area where many journals may reformat your work.
As for Nature and Science, I "created" the cover image for a supplemental issue of Nature Structural Biology quite a few years ago. For covers and promotional things, their art department gets involved and the final image may only look vaguely like what they were sent in the first place. Really, I probably could have sketched something on a napkin instead of spending time trying to make a decent figure in the first place with the changes they made in the end (though we did get to give our approval for the final image). As for the associated review article, the figures were all published as submitted; one of the editors may have asked for a change, but we would have made it ourselves.
I think both parent and GP are somewhat correct. As a country, we do spend more than most other countries and get overall poor results. However:
We spend the money poorly. Most of that money should go to educational materials (books, pencils and paper, and even so to computers), teachers, and infrastructure (buildings, heat, electricity). However, most districts have become pretty administration heavy; I've seen towns with one elementary/middle school and one high school that have both a superintendent and an assistant superintendent, both making 6 figure salaries. I've also lived in the south, where a district "couldn't" afford textbooks, but could afford $2M for a new football facility plus pay for 5+ full time coaches.
At the same time, we don't pay teachers particularly well. Sure, a 20+ year veteran teacher is probably making $60-70k in a reasonably well off district, but probably starts around $30k, less in some areas. So what we get is far from the "best and brightest" going into teaching as a career.
The money that is there doesn't get distributed at all uniformly. Overall, I'd say that the poorer (and incidentally more rural) communities tend to have worse outcomes. There actually are plenty of good public school systems in the US, but they tend to cluster in areas where parents tend to be better educated themselves or at least care about education for their children and that tend to be better off financially - no surprise that the two tend to go somewhat hand in hand. And on top of that, crap like "no child left behind" all but guarantees that the districts most in need of increased funding get less.
A diff should be just fine. Parent talked about individual preferences for rendering (i.e. displaying) a tab. So as long as the editor maintains the tab character when saving the file, all should be well.
If, OTOH, some screwed up editor "renders" a tab by converting it to some number of spaces and then saves that...
Sadly, I'd have to say it's probably up to the prosecutor to determine whether or not to file charges and then up to a judge to determine whether or not to allow a case to proceed. The legal definition is pretty vague and subjective.
I believe it was Ed Meese during the Reagan administration who, when asked how he would define port, answered to the effect of "I can't give you a definition, but I know it when I see it."
I'm sure/. will correct me if I'm attributing the quote incorrectly.
I've actually been wondering something as I read through all the comments, and it's unclear from the original question. Yes, the kids have multiple passwords to multiple sites, but does each child have a unique login/password combination for each site? Around here at least, it seems that the schools and libraries have one institutional subscription with a login/password to each (paid/commercial) resource, and that gets divulged to and shared by all students/patrons using that site.
If each child has his or her own set of login credentials, many other commenters have pointed to various "password wallet" type solutions.
If this is instead set up as I put forth above, I suppose the students could still use one of these apps and just put the school's credentials into it. But I think a better solution in this case would be for the school to set up a private portal (VPN, website, or whatever), give each student and anyone else who needs access a single, unique login, and have links through said portal that redirect to the various external sites with the correct credentials. That way you're only asking users (especially younger children) to remember - and keep secure - a single username/password combination.
As the parent suggests, access can be IP based, and by connecting to the portal/VPN, your device at home appears to be coming from the school. That's exactly what the university I work at does, for example if I want to access various online journals from home. They even have it set up so I can initiate the VPN session by visiting a website.
OK, 100% in agreement that there should be more emphasis on reproducing results, but someone needs to step up and pay for it - the current funding situation is far from pretty. Also, in the current "publish or perish" climate, nobody is going to spend time working on reproducing somebody else's results unless it directly impacts their own work. So we'd need to change that mentality as well.
However, if you truly believe that reproducibility is part of peer review, I've got a bridge to sell you. With most (all?) journals, reviewers aren't paid. The time they spend on peer review is typically spent AFTER they put a full day into their own research; their home institution doesn't expect any less output. They get minimal if any recognition for it, in an academic position it checks a little box for "good scientific citizen" and maybe puts a bullet point on a resume/CV. Sure, they'll ding the paper if the claims seem outlandish, or something just doesn't seem to add up, or grandiose claims are made with a sample size of n=1, but they generally expect that the submitting group has done the controls, the replicates, etc. The purpose of peer review is for the paper to pass the sniff test, not to guarantee there's no fraud.
While using a Dremmel is fun if you have one around, you can also get a set of security bits. IIRC, I got the smaller set at Harbor Freight for something like $4.
Frankly, I think we (meaning: those who design these sorts of things for a living) can deal with the issue of condensation out of the air.
The big problem today is that so-called "high temperature" superconductors all have less than desirable properties. Some are amazingly fragile; some superconduct but can't really be worked/machined in any meaningful way; some are so difficult to make (at least reproducibly) that they can't be used for anything more than research. It's great we've gotten this far.
As a practical thing, most of us who make use of superconductors would be absolutely THRILLED if we could get a good, workable, and ideally strong superconducting material that operated even a little bit above LN2 at 77K. Any remotely useful supercon material needs to be cooled with liquid helium, which is both non-renewable and expensive. Our little NMR facility (3 magnets) spends over $30k/year just keeping the magnets cold so they can be used as something more than very expensive paperweights. And we actually get a "good" price on LHe.
I've got to basically agree. Furthermore, while tritium tends to be pretty strongly regulated because it's (mildly) radioactive, deuterium is relatively easy to come by. The natural abundance of deuterium is ~1% of all hydrogen. You can separate D2O out of water by distillation, or you can skip this step and just buy it. I can buy a kilogram of 99.8% D2O for $300-400; that's with a discount, but full list is under $1k, well within the means of any determined terrorist. If you hydrolyze that, about 20% of D2O by weight is deuterium, so getting a few grams to "boost" your bomb via hydrolysis would be trivial, ignoring the part where you have to prevent the deuterium + oxygen from dramatically recombining.
Basically, the terrorist angle is a red herring from someone with an anti-fusion agenda.
Even if it's not legally extortion (I think it is), it still violates the contract users have with their ISPs. My contract doesn't allow any such thing.
More than likely, if you have a residential contract with your ISP it has a clause to the effect of "we can change this agreement any time we like". True, you can cancel your service at that point without penalty, but in some (many?) places that might mean going without broadband, at least in the US. And how long will it take Comcast, etc. to come around to Rightscorp's way of thinking if they offer to split their settlement^W protection money? Sure, this could be a boon for some small ISP with morals and a backbone, but there aren't too many of those around.
True enough, but if I'm reading correct, OP was talking about the exact opposite - combining a pair of 110 feeds to get 220. For "normal" US household service, incoming is 220V, and any 110V circuit simply uses just one of the two legs, so you'll typically have roughly half of your outlets using each leg.
NMR/MRI? Better magnetic "mirrors" and/or "lenses" for focusing beams in things like the LHC or even just an electron microscope? Those are a few applications. OK, in NMR the highest field magnets are already >20T, but those have two major differences from this. First, they're wound coils that focus the highest field in a small area, where this appears to be basically a puck; presumably properly optimizing the geometry (and fabrication process to get there) will allow higher fields. Second, and perhaps more importantly, this superconductor operates at liquid nitrogen temperatures - no more need for liquid helium for cooling would be a HUGE benefit.
Finally, although I've read the Cambridge press release and it wasn't mentioned anywhere, I assume this is a world record for a high temp superconductor.
Just keep in mind that the fossil fuel industry is also getting big subsidies, by far larger than any renewables get, albeit in a different form. So I'm ok with your unspoken desire to get rid of subsidies for solar, wind, etc. just as soon as we also get rid of them for Big Oil, Big Coal, etc.
