Comment Re:16K is impressive (Score 1) 70

Many of the masterpiece films were filmed on 70mm which is about 4x the size of 35mm

Typical 65mm and 70mm frames are 53mm wide whereas 35mm frames are 22mm wide. That's only 2.4x wider (though the factor for area is greater, depending on which exact formats you're comparing). So 4K scales up to 10K and 16K is enough oversampling for a mastering scan. Remember that 4K refers to the number of pixels across the screen, not to a total pixel count.

The list of 70 mm films isn't that long.

IMAX is bigger again, though mostly in frame height. Its popularity has taken off as technology makes it more affordable but the list of masterpieces on that format is very short.

The US ranks #11 globally for passenger-miles traveled by train

Now try passenger-miles travelled by train per head of population. Taking the 25-country list you're presumably using and dividing miles per year by population has Japan first with 3285 and the US third-last at 131. The average is 975. The list only includes countries with at least 5 billion passenger kilometres per year; there will be many others with fewer miles but which are far ahead of the US on a per-capita basis due to their small populations.

Comment Re:We need a better Unicode (Score 2) 95

This bug has zero to do with Unicode. The issue seems to be that the software generating the "&" doesn't realise that its output is being parsed and that it should instead be generating "&". Notice that all of the characters involved here are plain, 7-bit ASCII. We know this is true because ... this is Slashdot and Unicode is impossible. The fact that the ampersand is special in this context is nothing to do with Unicode, in which it has the category "other punctuation".

Well it's either that or have no anti-virus. In this case, other companies recovered faster than Delta, but it would be easy for AV software to screw up much worse and trash all the hosts to the point of requiring OS reinstallation. That's going to be very bad for any large business.

Criminal Negligence sure

Gross negligence is just a greater degree of negligence, commonly described by words like wilful, wanton and reckless. Criminal is worse, e.g., involving intent to do harm. Not that there aren't contexts in which gross negligence is criminal, like in situations where there's a risk of injury or death. This is part of the reason some software companies ban the use of their products in medical and nuclear fields.

I agree that the only correct character to use as the apostrophe should be the actual, ASCII, 0x27, ', apostrophe. The problem people have with this is that it looks horrible typographically because fonts generally have a vertical symbol (so it can also work as an opening or closing single quote). The correct fix is to use fonts where the apostrophe looks like a closing single quote. Obviously that's a disaster for coding ... so code with a console font. There are plenty of common fonts that are ambiguous about O and 0, and about 1, l, and I, so why care about apostrophes looking the same as closing single quotes? There are separate acute accent and prime symbol characters for use when those are required.

Editing prose (with a console font) is way easier when the open quote, close quote, and apostrophe characters are all different. Spell checkers aren't confused about closing quotes being part of a word and checking for broken pairs of quotes becomes trivial with regular expressions. LaTeX does this right, accepting an ASCII apostrophe in the input and producing the correct output. All the "smart-quote"-like WYSIWYG solutions are always breaking on edge cases.

Comment Re:Excellent, if affordable (Score 1) 52

There are the M-disc variants of CDs, DVDs, and BDs. These can be used with some popular brands of burners and work by deforming a layer, so they're not prone to dyes fading. It's cheap for an archival system and the discs are readable by standard hardware. Sure, Blu-ray drives might not be common in 2045 but they should be obtainable; at least you have a better chance than with some new, special-purpose technology that might never take off.

Comment Wrong metrics (Score 1) 59

Everyone knows SSDs are more expensive than spinning disks when measured per byte stored, whether you care about dollars or CO2, but strangely they're very popular. SSDs have speed advantages that make them worth their costs but this article ignores those. If my workload demands high IOPS then I might be able to get by with ten or more times less SSD terabytes than spinning disk terabytes.

Comment At least A/C Aligns Better with Solar Power (Score 3, Insightful) 68

as compared to data centres The biggest demand for cooling is mostly going to coincide with sunny days when solar power should be plentiful. The match isn't perfect---there are plenty of hot evenings after the sun has gone down---but it's better than data centres which tend to power on 24/7 to pay for all that expensive IT hardware ASAP.

The difficulty and expense with renewable energy is the storage needed to align generation with demand. Solar panels are dirt cheap but grid-scale batteries and pumped hydro are still very expensive. So A/C might use more electricity than data centres but still be less of a problem.

Comment Re: Megawatt (Score 1) 275

What you're referring to is a battery pack, not a battery. A battery is a single cell.

Absolutely not. Semantic drift hasn't taken us that far. Originally, if you used multiple cannon to batter down a castle wall, that was called a battery of cannon. When electrolytic cells were developed, they soon chained them together and called the result a battery. And we have 9V batteries still, and they're just batteries, not battery packs.

Now consumers describe things like AA cells as batteries and that's become common, accepted usage. The pedants have lost that one. But people trying to tell us that a group of cells connected together can no longer be called a battery, but only a battery pack, they're going to lose that one.

Comment Re:Australia has shut down both 2G and 3G (Score 1) 56

I live in the suburbs of our nation's capital and since the shutdown of 3G I can't get a mobile signal*. The public transport network here (and many other cities) had to replace their ticketing system because it used 3G.

The public transport system in Canberra had a planned upgrade from its MyWay to MyWay+ in progress many months before the 3G shut-off. Its main purpose was to modernise the ticketing system, allowing tapping on and off with ordinary credit cards or using your mobile phone. That fact that they ran close to the 3G shut-off was due to the usual government IT project delays.

Comment Re:Time is just one variable (Score 1) 98

And it's not great, because even at airliner altitudes and speeds, that atomic clock will drift, thanks to Einstein.

Aircraft know their speed and altitude pretty well, even without GPS, so this would seem to be easy to correct for. Wind would be the largest uncertainty, because it makes airspeed different from the ground speed, but I guess you could still reduce the atomic clock drift due to these effects by an order of magnitude.
