Comment: Whine of a camera flash charging (Score 1) 790

by BevanFindlay (#48796919) Attached to: Ask Slashdot: Sounds We Don't Hear Any More?

As well as the other camera sounds mentioned, there was the whine of the flash capacitor charging, which started high-pitched and quickly went up above audible. My best memory of that was being on the lighting crew of a stage production and accidentally holding the camera next to my headset microphone when the flash started charging - and the subsequent "Augh, don't do that!" in my ear. Not quite sure why (though I could guess), but the microphone picked up the whine so much more than you would normally.

It is kind of sad that my kids probably won't ever use (and therefore understand) film - or any kind of tape for that matter (except the sticky kind).

You do still hear the hour beeps in a large enough group (University lectures a couple of years back, if they went over time). Not as many as you used to get, but still enough to notice. And I always found it amusing how wide a range of times people had - there was always one who was several minutes later than everyone else.

While this won't affect most of us much (as the US DoD-operated GPS is still fine), it does beg the question of what caused the problem — is it related to the recent issues Russia has been having with its neighbours, did someone hack the GLONASS satellites, or is it just a bug? News via a surveyor friend (email quoting the Australian GPSNet) is that the satellites have to wait until they pass back over the base stations in the northern hemisphere to be reset, possibly taking as long as 12 hours.

I was about to ask how many people were going to do that... :-) (Or, if anyone really does have that as an SSID). Maybe we could start a geocaching-like game where you have to find a network with that name and leave a message... (Perhaps we all make the password "slashdot"). Could be a fun way for Slashdotters to make new friends.

DSLR? A decent compact will out-perform a phone camera by miles. We have a cheap-ish Canon Powershot, and the comparison between the shots it takes and any iDevice pictures I see people come up with? Not even close. Anyone with a basic understanding of optics could tell you why, too: lens size. Phone or tablet cameras will always be grainy, because of simple photon count (unless you extend your shutter time, but then you get blurry messes).

Yes, an iProduct is "good enough" for most people, but that's because most people have a bad eye for picture-taking or picture quality. Some of us have higher standards (and, I'm not even close to being a pro - I leave that to some very skilled friends of mine).

Maybe it's because I have kids: ergo, everything photgraphable is "live action", and often indoors.

Comment: Re:Is that 50 percent per interceptor? (Score 1) 266

The laser-equipped 747 brings up an interesting question: could the US have anti-missile tech that we don't know about? (e.g. say they mothballed it, but only because it worked too well, meanwhile building an upgraded version in a quiet corner somewhere). I know that if I was the US president, I'd task some very smart, very well resourced people with a plausibly-deniable mandate of: "Find a way to stop ICBMs, just don't tell anyone." Not doing something like that would seem insane. Now, of course the possible answer is that it's simply too hard, but if a missile really is just "ballistic", then it shouldn't be difficult to work out how to hit it (multiple entry vehicles etc obviously make this exponentially harder - after all, it's why they exist - but that suggests to me that maybe a simple ballistic missile shouldn't be too difficult to stop...?)

The next thing I would do after developing and testing said tech is make sure that nobody found out and keep playing the MAD-fear game with everyone else, saving the advantage for if it's really needed, and to avoid anyone trying to "limit test" it.

Shh... Let's hope that NK isn't that smart. :-)

Also, smuggling a large object that is highly radioactive isn't actually as easy as smuggling most other things, as it sorta has a very obvious signature, and a lot of border controls have detectors for this (it's not hard). Having said that, the US has a lot of coastline...

Assuming you get a decent-sized nuke into place and detonated somewhere populous, you then have the choice of, (a) don't own up and quietly laugh at your own destructive power but still have no one take you seriously, (b) own up and wave as Uncle Sam sends a few precious birdies your way (no better than attempting your own missiles, except that you actually did score one hit).

It is a scary possibility though.

Comment: Re:Science is the antithesis of religion... (Score 1) 528

A good scientist (I think) is one who approaches every question from three angles: (a) What does the question look like if I'm right?, (b) What does the question look like if I'm wrong?, (c) What does the question look like if I make no assumptions whatsoever about the outcome? The latter is actually really hard to do (and probably can never be done truly on anything).

I would say that someone approaching the world with "I am a rational being, created by a rational god to live in a rational universe with the ability to learn about it" probably isn't a wholly bad way to approach science. It would certainly be better than "I will look for any answer, except one I don't like", which I see from a lot of atheists as well as a lot of Christians. But, having said that, a scientist needs to be "agnostic" about his work - general rule: never trust anyone's research if they're doing it with a point to prove (a lot of "funded by" research tends this way).

Also, I would say that to be a good believer, you should question your faith. IMHO, faith that hasn't been tested isn't really faith. It scares me the number of people (in all sorts of realms, and from all sorts of beliefs) who don't question their core beliefs. Though, I can understand it to a degree - big, "meaning of the universe" questions can be scary (as is "what if I'm wrong?"), but one should still ask them, and frequently. It's a good antidote to becoming a freaky religious weirdo (atheists can be this, too - and actually, so can agnostics even, though it's a lot rarer). :-)

Comment: A real question for Dr Bakker (Score 1) 528

I'm interested to hear how you reconcile Genesis with the fossil record - what view do you take on how what the Bible tells of creation, the Flood, etc fits in with the observable fossils and geological records (being that presumably you have belief in both the Bible and nature being sources of truth)? Additionally, do you think that young-earth creationism can fit with the fossil record?

P.S. I am a Christian myself - I am interested to hear what a real expert says on the topic, rather than second- or third-hand variations of the facts, or repetitions of uninformed bias (from various sides).

Agree. We have similarly stupid password rules at my work, along with forced password changes every couple of months or so. (And, forcing password changes on a regular basis of course simply results in people writing down the passwords, so please, IT admins, don't do it!) (Example reference here).

XKCD's excellent commentaries have already been covered to death, but I wonder that no one seems to have thought of having a password-checking routine that does away with idiot rules and simply checks against a periodically-updated list of the most common passwords (sort of like a rainbow table, but I'm stretching the definition somewhat). So, disallow "P@ssword1" (which is a dumb password, but passes almost every rule set I have ever seen), but let someone have "beagles twirl widdershins up my saxophone" (which was suggested in an article on passwords... oh, about a decade ago, and I still remember it because it's very hard to forget).

A complex system that works is invariably found to have evolved from a simple system that works.

Working...
