The problem is you don't always know. Simply look at plastic baby-bottles containing BPA.

For starters : congratulations on your son. I "admit" I never 'gave up everything' for whatever reason but I do know the impact of having children on one's life and point of view. Welcome.

Secondly, I'm not here to judge but merely to point out you were literally suggesting people should not pay for transport in SF if they don't feel like it; all the while complaining on your website that the current generation is one that simply takes things for granted as if they are entitled to whatever they want.

It's ironic how you blatantly state the above but put the following on your homepage:

(emphasis mine)

"I don’t think I want to be in the western world when it collapses. I think we are such a violent bunch that even I might not survive, and I’ve spent years homeless, did time in Iraq, and so forth. I still don’t have faith I’d be able to guide my family through the chaos of a societal meltdown in a culture which is so coddled and takes so much for granted. I think we need to GTFO here and definitely within the next ten years."

If only 'the other people' were a more ethical bunch eh?

I'm assuming the parent is European (Renault Laguna) and we tend to talk about fuel-efficiency in liter per 100 km. Hence, a lower number actually means better efficiency in that context, hence the confusion.

FYI: My dashboard allows for these 3 options: MPG, l/100Km, Km/l. I actually like the km/l as it is much more interesting and also has better 'scaling', but sadly the l/100Km is most widely used in that respect that I'm pretty sure that if I would say I got 20km/l on a given trip I'd probably meet blank stares only =)

Interesting, didn't know about the last part being 'in theory only' (nor its name)
thx.

Using toaster-size satellites, I very much doubt so.

I seem to remember that doing so is impossible using 'normal' optics due simple physics. IIRC there is a limit to the resolution (expressed in radians) you can get for a given frequency for a given lens . Given the distance above our head these things fly this means there is a 'hard' maximum resolution these have and given what I remember from the article it was quite a bit above the ability to read the screen on your phone. The same /article/ (for the love of god I can't remember whether it was in print or some blog or something) stipulated that those pictures you see where they show you the playing-cards a man is holding are actually aerial pictures taken from specialised planes who happen to fly a LOT lower to the ground and also can carry big (heavy) lenses more easily.

PS: I mention 'normal optics' because apparently (same long forgotten source) it should be possible to get much higher resolution by combining different satellites looking at the same target but flying some distance apart and combining their 'view' using some fancy mathematics.

Doing some googling I stumble upon this that seems to conform the above : http://cosmoquest.org/forum/archive/index.php/t-2500.html

Food markets you say ? Hmm, I recently saw this documentary where they bought a car-wash... heck , they almost bought 2 !

ps: they also mentioned nail-salons

Well, here I have mostly CFL's everywhere with some 'experimental' LEDs here and there too.

When they were on sale I bought 4 of these : http://www.usa.ecat.lighting.philips.com/l/professional-lamps/led-lamps-and-systems/led-lamps/a-shape-led/929000201804_na/
I replaced 2 21W CFL's with 1 of the above and the general 'complaint' was that the new light is way too bright. In reality it probably is less bright but it ramps up to 100% pretty much instantaneously while the CFL's would take some warming up thus giving your eyes time to adjust and hence being subjectively dimmer. I very much doubt the energy savings will ever make up for its price (I paid 35 euro) but given its location it's quite useful that they are full power right-away because people usually only light it for about 2 minutes and then are out again. AND I'm hoping they'll last (a lot) longer than the CFL's which I've had to replace too often in that location; probably because of the fact they get lit quite frequently but only for a short while which is deadly for that technology. I know LEDs don't mind switching on and off but off course I have no clue about the electronics that drive them.... time will tell.

I guess it depends on the subjects you're interested in. Given the size of SO (well, we should probably consider the entire Stack Exchange group, no ?) there's bound to be sub-cultures. Personally I rather occasionally browse the SQL related tags and while there are quite a bit of 'Please do my homework' kind of questions, those often don't get the answer they're looking for (that is: the worked out solution) but rather get pointers into 'the right direction'. Luckily there also are also quite a few of interesting questions that spark discussions and often-times indirectly gives me some insight into something I hadn't ever thought about before. I find that valuable. Feel free to look up my userid and you'll notice that hardly have any reputation points behind my name; in fact I have 'worked' just enough to be able to post/edit comments etc; otherwise I really don't care.

A long, long time ago I used to spend quite a bit of time on ExpertsExchange. Although I enjoyed helping out others at first it became quite frustrating after a while to see how a few people would throw a quick & dirty solution only seconds (?!?!) after it was posted. By the time I had written a fleshed out answer the original poster would already have accepted the (imho) downright terrible advice and there was no way to undo the situation except for adding a comment along the lines: please don' t do it like this for reasons x, y and z. I had no clue why (or how) these quick-posters would do this as their reputation already was sky-high until I noticed that the site had leader-boards that would nominate their 'best' people on a monthly/yearly basis. After that I gave up.

At least on SO you can down-vote a prematurely accepted answer and vote up one that makes a lot more sense. Maybe the original poster won't care to come back, but at least when someone comes around googling for an answer he'll be presented with the 'better' answer first AND the Q&D poster actually gets 'punished' by the down-votes. (As are the people who down-vote, so it's 'harder' to game the system). I'm sure SO has something like 'greatest contributors' too, and yes, there is all the badges and reputation stuff; but it seems to me there is a lot less attention given to it.

Seems like a fun challenge for any (serious) keylogger author out there. Probably will add a couple of hours of the more fun kind of coding to his 'job'.

I'm not saying it's a bad idea, but it will only help out against the very basic keyloggers. Then again, it WILL protect against hardware keyloggers that sit between the keyboard and the computer as those have no access to the clipboard. But in that situation simple auto-typing or simple copy-pasting would be sufficient.

75 kg/m2 per year
three crops annually as in : harvesting 3 times / year.
Thus, per crop = each harvest = 75kg/m2 divided by 3 = 25kg/m2

Like I said, it might differ by region, but most 'modern' houses around here that I know of have concrete floors/ceilings (**) except perhaps for the top-floor and the attic/roof that indeed most often is built around a wood-frame. I somehow associate wooden floors with pre-1960 tech but I might be biassed =)

(**: pre-tensioned hollow concrete slabs, not a clue what the correct word might be in English, https://www.google.com/search?q=welfsel&tbm=isch&tbo=u&source=univ&sa=X&ei=V213UqqKF4SZ0QWk2YGgDQ&ved=0CEYQsAQ&biw=1920&bih=840 )

If by 'those houses' you mean European houses then I beg to differ. Although it might be region specific off course. Around here (Belgium) there is a minority of houses built by means of a wooden frame that then gets 'bricked in' (although they more often go for plastering or another type of siding in my experience); but most houses are constructed using bricks & mortar only. Well, that and concrete and steel and glass etc... off course. AFAIK it's always been like that.

If the house I'm sitting in right now would be set on fire somehow it'd be mostly the furniture and stuff that would go ablaze. I wonder if it would even get sufficiently hot to actually ruin the structure. Oh, and if the fire would reach the roof that would be total-loss indeed, as it rests on a wooden frame.

Meaning we'll all have a micro- mobile swimming killer bio reactor in 10 years then, yay for progress!

Off course these disks do not know anything about the filesystem at all; all they do is look at the raw throughput. There is something to be said about the OS knowing which files are worth caching and which not; but in the end the cache on the SSHD will come to the same conclusion as it simply keeps track about which blocks of data are most often requested. Plus, having an SSHD doesn't magically sabotage your system cache.

Like I said, you may find all sorts of reasons to not like it, in practice the thing delivers on its promise. It's far from perfect and it can be fooled into taking the wrong decisions but that's not a terrible thing to happen as it will 'heal' over time.

Example : my laptop used to have a Momentus XT and although the older model has only 4Gb cache, it booted faster, had Visual Studio open in A LOT less time, could bring Excel up in 2 seconds, same for SSMS, Firefox would load faster, etc ... I very much doubt all of those programs fit in those 4Gb but still it managed to find out which were most 'important' as the loading times of ALL those programs (os) were remarkably lower ALL THE TIME vs my colleagues' machines that were pretty much exact copies safe for the fact they had the original 'ordinary "black" whatever disks". At a certain point in time I had to run a virtual machine for a while and -not entirely unexpected- after a couple of ''virtual reboots' said machine also started up remarkably faster, programs inside it got faster to load too etc... but all of this came at the expense of slower loading of eg. VS when started 'locally'. After the VM-project was finished it took a couple of days for everything to turn back to normal and I guess if I had kept the virtual machine and started it up again then it would have been its original 'slow' again.

Currently I have Samsung EVO Pro + that WD Scorpio Black in the media-bay. The SSD feels 100x faster than did the SSHD but I noticed that having the XT as data-disk (used pretty much only for backups & multimedia) didn't really make much of a difference vs a normal disk as the access patterns were simply not appropriate for it. So I put it in my little file/media-server at home where it makes more sense.
