it's more than that. i cannot get to my (presumably clean, running linux, carefully maintained) home machine situated in chile, connecting from the uk. -----
 what an awful diagram. it implies there's some kind of symmetry that relates all four, but when you look at the details there are asymmetries. if you think it was helpful look at it again and explain why di appears in two quarants but dq and dv appear once each. -----
 You can rearrange the inductor equation to get di = (1/L) dϕ. Then the quadrants are perfectly symmetrical except for the ugly 1/L. But that's just an arbitrary unit created by humans, you could fix that by defining the unit of inductance as the inverse of what we use now. -----
 ah, thank-you. that makes more sense. -----
 are you sure you're looking on both sides of the equations? -----
 you want mode, not median. there's no reason to think that the background is close to the median colour. that's kinda the whole point of the article...(median works well if you have symmetrically distributed noise, which is true when denoising astronomy photos, for example, but not here). -----
 I was thinking the same thing, but for sets of images where the occluding items are a relatively small percentage of the image area (and are moving around enough between frames), taking the median pixel value is effectively the same thing as the mode, but faster. (e.g. if you take 10 frames, the 1-2 frames where a pixel is occluded will almost certainly be an outlier to the 8-9 frames where the pixel is almost exactly the same, and the median will take the value in the middle of those 8-9 frames.(Another problem with mode is that you'd have to posterize the image to ensure that shifting light, noise and camera movement don't cause the values of background pixels to vary slightly. Mode is much more brittle in that respect.)If I recall correctly, Lightroom / Photoshop has a handy "median" filter, but no mode filter, which is why the popular method uses median. -----
 i just wanted to say thanks to the truecrypt devs for a decade of largely unthanked and criticised work that, as far as i can tell, has been impressively reliable.[kinda disappointed that, despite arriving so late to this thread, no-one seems to have said this.] -----
 just want to second uml distilled. if you need to use uml you should read it - it's very slim and very practical. http://martinfowler.com/books/uml.htmlalso, uml with a tool like enterprise architect (which is basically a set of gui interfaces onto a database, where you construct a design in the database using the views, and are forced to be consistent) is very different from sketching a few diagrams.it's not for me, but with a good tool you can see the attraction in certain scenarios. -----
 when openssh uses certificates it still uses its own protocol (even with the x509 patch - without that, the certificates used by openssh are not even the same kind of certificate as those used by openssl).the problem with the openssl library is in the implementation of the TLS protocol. this is not used by openssh. so openssh is not affected by this problem. even when certificates are used. and even when x509 certificates are used (which requires a separate patch). -----
 can you give a hint? i think i understand the article (well, i haven't read it, but i sometimes need to tailor code to work better with the cache on a cpu), but i don't know what you're referring to. -----
 Memory speed vs cpu speed doesn't include caching technologies. -----
 a simple, motion-sensitive sleep alarm. i just tried to find one, but they all require a phone or tablet. they're nothing simple and stand-alone with a very basic interface. -----
 Would this have the same motion detector as the soap dispensers or maybe out-door motion lights? -----
 they seem to use accelerometers - either in your phone/table (which you have to then place on the mattress under a sheet) or in a wristband or watch. -----
 What is a "motion-sensitive sleep alarm"? One of those widgets that wakes you up at the most advantageous part of your sleep cycle that falls within a given bracket of time? ISTR seeing one of those a while back, in production, which was built on the wristwatch form factor and didn't need to integrate with an external device; if indeed that's what you're looking for, I'll see if I can turn it up and post info about it here. -----
 yeah, one of those (thanks). edit - knowing it was a watch i've found this - http://www.sleeptracker.com/ but if you have something simpler / less expensive / more attractive to my partner (less nerdy looking) i'd be interested. edi2 - ah, also http://www.axbo.com/pages/shopso i guess to correct my original post - something more like a simple, traditional alarm clock. with less obvious tech. but that somehow works this same way. basically just a clock display and some buttons to set the alarm time, and i guess some kind of wearable sensor. -----
 The Zeo Sleep Manager Pro [1] looks like probably your best bet. Unfortunately, Zeo closed its doors about a year ago, which may make it difficult both to find the product available for purchase in the first place, and to get support for it once purchased. That said, phone integration appears to be otherwise ubiquitous in the field, at least judging from the few minutes I've spent poking around Google and Amazon; that being the case, your choices may well reduce to either accepting phone integration and making the best of it, or finding a way to get your hands on an orphaned product and making the best of that. -----
 i've stood my ground for my beliefs when people were ridiculing me for doing so. it's a lonely position to be in.i didn't share eich's views here, but he's free to have them, and the reason for the problem is, ironically, the intolerance of other people (people forcing their "tolerance" down his throat).he has my respect. not for his view on gays. but for staying true to what he did. i think this is a shame. -----
 Except he didn't stand his ground at all. He never once explained his beliefs. If he had done that I think people would've been a lot more tolerant of him. I don't think it had to end this way. -----
 Sure it did. The knives were out.Is it a requirement to explain what you believe? You can't just state it? I mean, there's no rational reason to oppose gay marriage, so attempting to rationalize it just comes off sounding stupid. Should we force a person to say stupid things?Maybe what you mean is to demand a conversation. Forcing someone to participate in a conversation doesn't seem right either.Does a person have the right to be close-minded? -----
 > Is it a requirement to explain what you believe? You can't just state it? I mean, there's no rational reason to oppose gay marriage, so attempting to rationalize it just comes off sounding stupid. Should we force a person to say stupid things?Someone who is CEO of a very public, very community driven company? I think it's reasonable to expect him to participate in a conversation about his beliefs, especially when those beliefs do not seem to reflect those of the community he represents and the community is a core part of the business. That conversation seems to me to be a part of the business itself.He doesn't have to believe certain things, but to be an effective CEO he has to have the community respect the integrity of his beliefs. He didn't even give them the opportunity to do so, and then complained that he was being witch hunted. All he had to do was say "No, actually I'm not a witch." Instead he said "I promise I wont speak any spells." This analogy is getting a bit silly, but you get my point.> Does a person have the right to be close-minded?Absolutely, and a person has the right to be close minded and run a company as well! This has NOTHING, let me repeat NOTHING, to do with Eich's rights. -----
 Except that personal beliefs are just that, personal. You don't have to explain them. -----
 Assuming people can logically explain why they're LGBTQ. Most of the time personal beliefs are irrational. -----
 Except he didn't stand his ground at all. He never once explained his beliefs.He did stand his ground in terms of what his position meant at Mozilla, explaining it on his own blog and doing interviews. -----
 so what? my impression is that colin is happy with things as they are. why should he change his business, which makes him happy, because someone else thinks it should be different?the aim of life is to be happy, not to meet someone else's expectations. -----
 I'm intentionally value-agnostic about whatever makes Colin happy in the post. As long as operating businesses suboptimally is not in fact his terminal value, there exists a transition between Tarsnap and Tarsnap' which makes him even happier. Everybody wins, especially Colin, which strikes me as a happy outcome because I like seeing when geeks are suitably rewarded for creating substantial improvements to the world, which Colin has done.If running Tarsnap as a free public utility is the light he wants to bring to the world, the outlined Tarsnap' is better at that than his Tarsnap is. Charge businesses more, invest in better UX, subsidize non-business users straight to "free." If he wants to lay on a beach sipping iced cocoa, this is more beach and more cocoa. If he wants more time with his family and less time in the inbox, this is a trivial modification away from that. ("Make money, buy your way out of inbox.") -----
 maybe he needs someone else to show him how to be happy.shrug. in my experience, people telling me how to live my life tend to be a pain in the arse. but maybe i am projecting. -----
