you're overstating the differences between a DO and an MD. really, it's mostly that DOs get more training with physical manipulation and examination, and the quality of their programs varies more substantially. there's no significant difference in structure or underlying philosophy; one isn't more reaction-based than the other.
oh, and DO or MD only refers to their med school education, before they were a resident. you often see doctors of one type in residencies of another (at least in the primary care fields; i'm less sure beyond that). i'd consider that training much more significant to understanding how a given doctor practices.
I use venti, an archival storage system originally develloped for Plan 9 from Bell Labs and now available on a host of other systems via Plan 9 from User Space. Venti is strictly archival: it stores blocks permanently. This storage is organized into "arenas", or pools of a fixed size. When one arena fills up, it is sealed, never written to again, and the system starts dumping bits into the next one.
Primary storage for my venti system is a pair of mirrored SATA disks. Yes, magnetic disks can fail, but with mirroring they're still cheap enough to almost certainly be your first line of defense. When an arena fills up, I burn it to CD (by default, they're 512MB each) and mail that to a friend three time zones away. If my house burns down, I can recreate everything up through the last arena by basically dd'ing the contents of those CDs to a new disk.
Using a real archival system has other neat benefits, too. You don't have to worry about whether you saved the right version of something, or how to organize different versions over time; it's all automatic. I've used this for "work stuff" for a long time with very good results; after my last laptop hard drive crash, I've started using it for personal stuff (although I haven't made that quite as automatic yet). I can now "cat/n/dump/2008/0712/usr/a/src/cmd/ngcscatgen.c" to see the version of that file as I was working on it over the summer. Pretty nice.
Both NPR and Wired are running stories about how nearly two decades ago, a dogged, absentminded Canadian geologist named Charles Fipke who was practically down to his last nickel when he discovered diamonds in the Northwest Territories...
did what? there's no action clause here; they're all turned into adjective clauses about Fipke. go ahead, diagram it for me. you could just remove "who" or "when he" and it'd make perfect sense.
on the up side, this now removes any doubt as to whether grammar on slashdot is getting worse or i'm getting more persnickety: it's me.
there's a lot in here i'm skeptical of. you assert that existing routers tend to favor TCP over UDP. can you support this? clearly it would be easy to do%2
it's true that the protocol stack would need to have some method of regulating retransmission, but i think the GP's point is that it's already there, in the BT applications. sure, it's not at the layer we tend to think it belongs, but when you're dealing with untrusted sources (as anonymous seeders inherently are), you've got to do that work anyway. also, even if you ended up recreating a "subset" of TCP, that could still be fine. TCP is huge compared to UDP, and if you use UDP as a base for adding what you need, you can still come up with something much simpler than TCP; see, for example, RUDP. TCP's benefit is its ubiquity, but if you have the combination of a constrained enough environment and wide enough client distribution, that's less of a big deal. BT and uTorrent likely satisfy those requirements.
Even my stupid cable box has DHCP on the DVI output...
really? huh. i guess at nearly 4Gb/s, DVI would make a pretty good data carrier, but in a point to point link like that, do you really need dynamic host configuration? it seems like a waste to even run IP over it, although i guess that's all most OSs understand these days.
it's not just him. there's some weird internet culture i don't understand where if you use products from a certain class of company, you're automatically a fanboy (and WTF's with the "i"?). Apple's probably the most widespread, but i've seen it with Google, and various video game companies, at least. i really don't understand the emotional place this comes from. i think there's often an element of jealousy, but it's deeper than that. charitably, i'd say they're confusing the fact that some product/service doesn't meet their needs for the idea that it therefore can't meet anyone's, and anyone who chooses it must be doing so based on the status value, or hype, or something.
in both the pager/phone and grep/sed/awk cases, you don't see the point in using multiple tools because you don't really understand the capabilities and limitations of the tools in question.
my housemate is a doctor. she carries a pager and a mobile phone for several reasons. first, there's the practical matter that the pager is louder and more noticeable, even on vibrate. sitting on the windowsill next to her bed, even vibrate is often loud enough to wake her. finding a phone with comparably difficult-to-miss notifications is likely possible, but dramatically limits your selection of phones. that's a silly trade off when she needs to have the pager nearby about half the time, but pretty much always wants her phone nearby. also, and i think far more important, is coverage. the pager is regional; it won't work if she travels a few hundred miles away. within the region, however, it works pretty much everywhere. i'm not actually entirely sure why, but it works out in the woods and in buildings where no cell networks get. none of the doctors i know care two licks about "status" associated with their pagers; they pretty uniformly hate carrying them around. if you could seriously suggest something which preserves their ability to pick a phone they like (which are generally not employer-provided) and provides the pager-class contactability the employer demands without having to carry around two devices, i'm certain they'd all be thrilled.
for the grep/sed/awk issue, there's things that're dramatically easier to do in one than the other. maybe not grep so much, if you've already got awk in the chain, but the other two certainly. backtick replacements in sed, for example, can be done in awk, but are awkward (no pun intended). also, things like that often grow organically. i've done awk programs for processing data, then found other data from other sources in slightly-different formats. sed (particularly the backtick replacements) can often pre-process different input types for the awk program. the awk program stays cleaner, and it's clear what's the main logic of the overall program and what's input massaging.
you realize that the N810 isn't a phone, right? it's a great device (i've got an N800 and had a 770 before that), but sandwiching it between a Voyager and an iPhone makes it seem like it's in the "smartphone" class of device; it's not.
yes, OS X's pbcopy and pbpaste are very nice. even better, though, is Plan 9's approach:/dev/snarf. it's just a file; read and write it with anything you like.
three is significant, in that it's the minimum needed for a robust system. in a two-group system, if one gets "uppity" there's nothing to be done about it; it now has the upper hand. in a three-group system, there's more avenues for keeping the balance.
having more groups doesn't make the system less robust, although it likely makes it simply larger.
and it's true that they aren't "equal", but the point is that they're not subservient and that each has some checks over the others.
that change had more disastrous consequences than almost anyone today realizes. it fundamentally altered the balance of power between the state and federal governments far more than anything since the civil war (and one could plausibly argue which was a bigger effect). compare the growth of our military before and after that change, and notice particularly the progressive, gradual federalization of the state's National Guard units. the states no longer have any direct, systematic method of checking the federal government, and instead have to rely on ad-hoc and after-the-fact methods.
having looked into much of this while designing alternative remittance systems, i'm fairly confident in saying that such a thing doesn't exist, or at least isn't recognizable as a bank. a few of the regulations designed to protect consumers actually make it very difficult to change from the status quo, and overall have the effect of making it expensive to try new things. things which don't try as hard to look like banks (paypal being the most popular example) have a lot more flexibility; those may or may not qualify for what you're looking for. i'm inclined to say not, until i can pay my utility and tax bills with my paypal account.
well, start with a human burning 704 kcal/hour going 15 mph on a bike, about 47 kcal/mile. petrol has 31,548 kcal/gallon, meaning that on the equivalent energy from one gallon of petrol our biker goes about 671 miles. i'm not sure what small engine you think you're going to be able to mount on a bike and have it to better than that.
there's plenty of good reasons to drive a car, too (like being able to carry two mates and our respective bike gear out to the mountain). but you seem to be claiming that having people switch to bikes for much of our driving, where practical, wouldn't have an appreciable effect. that's just stupid.
it's not a question of a line being drawn, but you have consistently diminishing efficiency. shocks aren't "bad", but they have costs. same for an enclosed cabin, headlights, 7-speaker stereo, whatever. and of course the biggest one is not having to power it yourself. you seem to be defensive about this for some reason; nobody's saying anything's "evil". just less efficient.
you have a lot of "one could argue" type statements without any apparent recognition of the fact that most of this stuff is very clearly quantifiable. one shouldn't argue about efficiency in some abstract, platonic sense when actual measurements exist. there's simply no valid comparison between the conventional model of shipping petrol from the ground to your tank vs. electrical vehicles. the efficiency differences are profound, even though the electrical model is built with far more generalized distribution mechanisms.
the law doesn't give bikes the ability to ignore physics, no, but it does give them the same rights. that means that other users of the road have the same responsibility to look for and accommodate bikers as they do all other users. sure, there's idiot bikers out there, but far too often reasonable bikers have to deal with drivers who think the roads are theirs alone.
i personally have nothing against cars, as long as they don't create a major obstruction to bicycle traffic.;-)
Palin's a class-warfare liberal. wow. you've got a pretty tweaked world view. more relevantly, you dramatically overstate the role of the FMs in creating this mess. the CRA may have had a negative effect on their activities, but they combined just don't make up enough bulk to cause this problem on their own. the need (perceived need; greed) of the lenders to get higher returns led them to take riskier and riskier actions.
1) i should have been clearer: for the parent's point to be valid, the citation/reference would have to apply to a statistically significant majority of religious folks (especially Christians). your link gives the view of one Christian and, arguably, official doctrine of the largest sect. but official doctrine frequently diverges from what the people on the ground believe. 2) yes, i do, in fact, mean "without any predictive power". in both cases, which means neither one is a scientific theory. therefor the entire premise of "denying science" is stupid and irrelevant. also, the "extraordinary claims require extraordinary proof" thing has nothing to do with Occam, and came many centuries later (by Sagan, i think). it's no corollary.
1) i understand what you're saying, i'm simply asserting that it's wrong and bigoted. you believe in science, right? please provide your evidence or citation that either (a) religion (particularly Christianity, as originally raised here) makes people homophobic, (b) some version of "true" Christianity (avoiding the "no true Scotsman" fallacy) is inherently homophobic, or (c) there is a statistically significant difference in homophobia amongst religious (again, particularly Christian) vs. irreligious people.
2) I agree Occam's razor is central to scientific rigor, but it doesn't say what you think it does. the razor helps determine between competing theories with equal predictive or explanatory power; the alternatives you've proposed don't fit that. "we don't know" is a perfectly acceptable scientific statement, but it's not a theory. "God did it" is a theory, an explanation, although clearly a very incomplete one without much predictive power.
