Yep. I recently acquired a inexpensive macro zoom lens. At 1:2-- yes, yes, it's not true macro-- I have to hold the camera very close-- a few centimetres-- to whatever I'm trying to focus on. At the faster f-stops, the depth of field is wafer thin-- a good photographer with a fast macro can make that lens "bulge" disappear. Most macro technique involves stopping down the aperture (and consequently needing to use some sort of flash) and focus stacking to get as much depth of field as possible-- neglecting to do so for artistic reasons is quite doable.

Somehow a quite conservatively formulated claim (subjunctive mode, "some models, 75% chance, 5-7 years, during some month of the summer") magically morphed into the strong claim "Al Gore said in 5 years time the Arctic will be completely ice free". How much did you pay for that perceptional filter? And can you get a refund?

Nope-- they would drop frames. The write speed is not sufficient for raw 4k video. It's good for about 1.5 hours of video, perhaps even more since 95MB/sec is the read speed, and not the (almost certainly) slightly slower write speed, and of course, it's unlikely that the camera will produce data at this exact speed.

The blackmagic cameras are typically used with SSDs. even though some SanDisk extreme Pro SDCards support 280 MB/s reads. This 512 GB card is hogtied by its slow speed, even though 95 MB/s would ordinarily be regarded as pretty speedy.

The range is 30 miles. Periodically, the busses will fully recharge in seven and half minutes.

StarMetro in Tallahassee, which has a fleet of 72 diesel buses, found itself coping with budget problems when the price of diesel spiked in 2007. Fuel is typically the second-highest cost for a transit system, behind labor. StarMetro was Proterra’s third customer, ordering three buses in 2010 and two more in 2011, backed by federal funds. “We put them on our most visible route,” said Ralph Wilder, superintendent of transit maintenance. The buses can easily handle the 18-mile loop, which runs from Tallahassee Community College to the Governor’s Square Mall. On this route, all buses stop for 10 minutes in the middle, to wait for connections, so charging up the electric ones doesn’t add any time to the trips. Recharging takes about 7.5 minutes.

So, $825,000 for the electric bus, but only $80,000 in fuel costs over 12 years, vs $447,000 for a diesel bus with $500,000 in fuel costs. In theory, economical, but there are also air quality improvements-- depending on how the electricity is sourced.

Just for your information, bicycles are part of the traffic! As for "interference", the appropriate control situation is not one where the cyclists are magically poofed to New Delhi (or the moon), but one where every cyclist is replaced by yet another car...

It is the job of a "scientist" to present claim and data that supports said claim in such a way that it may be consumed by anyone and still stand on its own, only then is there "consensus."

Well, the job of a "scientist" may be to provide soundbites that so-called think tanks can feed to sympathetic reporters and the uninformed public. But it is not the job of a scientist (no quotes) to present his results in a way that "anyone" can consume them. Scientists need to present their results in a way that an interested, fair-minded, and, most of all, sufficiently educated person (i.e. usually another scientist with a similar speciality) can follow the research.

Some complex research can be presented to the general public (although even then not to everybody), but then it's necessarily simplified and no longer iron-clad. It's a sad illusion to assume that modern science can be spoon-fed to a passive audience in a way that said audience can really understand it. If it were that simple, we would not need universities and Ph.D. programs.

"In a Reddit thread under the title “Every Man Is Responsible For His Own Soul” [sic], Mr Wong wrote: “I did not say ‘we won’t ban any subreddits ever’. I said that we don’t ban subreddits for being morally bad."

Mr. Wong, with all due respect (that's not much for the record). Horse. Fucking. Shit.

  If you make a rule against X (and ban X-related subreddits) but not rules against Y and Z, you're making a moral statement that Y and Z are more acceptable than X. There's just no other coherent reading of those rules. If you're trying to make a community where bestiality and racism are considered morally better than leaked celebrity nudes, that's fine - it's your site, but have the spine to fucking own it.

Quite right. Simple measures
