Stop Standardizing HTML

· Score: 4, Interesting
The author's proposal sounds suspiciously like he has fallen for the seductive path of elegant generalizations(that are too theoretical for the ugly details to yet be visible) instead of confronting the ugly details that our current attempt at standardization has made visible...
To be sure, the sausage-by-comittee that tends to result when you try to standardize something is quite ugly and takes ages to settle down; but if the proposal is "Just let people use whatever shims they want for everything" you haven't really solved the problem, just comitted yourself to standardizing a suitably powerful interface for the shims to sit on, along with giant piles of shim-dependent code that crawlers and any other applications that break the shims' assumptions won't be able to make the slightest sense of.
Heck, for maximum elegance in the core standards, we could just replace virtually everything with the "Object" tag, and let people embed whatever they want, or abandon this 'HTML' nonsense entirely and just make Native Client the standard, freeing developers to implement pretty much any conceivable structure, from a legacy browser engine, to a Flash client, to a TECO interpreter built entirely out of Minecraft redstone logic, as the shim for their 'site'. A glorious age of unfettered freedom!
Essentially all 'dual GPUs on a single card' products are mostly for e-peen(because of their relatively low production volume, it's pretty common to find 2x of the single GPU equivalents for rather less than the price within a short time, so they only really make sense if you are doing some absolutely nutty 4+ GPU configuration).
However, given the ability to ('eyefinity', I think they call it) aggregate multiple monitors into one virtual monitor(to allow you to paint applications that don't understand multiple monitors natively across multiple monitors), a 6-headed card could well end up pushing some serious pixels even if you go with cheapy 1920x1080 screens. That's certainly a niche case; but you could easily be running 3 of those for only 3-$400, so it isn't really crazy money these days.
nVidia's drivers have gone downhill of late and they're still better than AMD's.
Does anyone other than Intel actually have stable graphics card drivers? Is there a way to get drivers from AMD or nVidia which turn off the hackish "optimizations" and accept slightly lower FPS in exchange for more stability?
Sure!
Step 1. Choose the AMD or Nvidia card you want.
Step 2. Take the price of that card and add ~$1000.
Step 3. Consult list of 'FirePro'(AMD) or 'Quadro'(Nvidia) cards.
Step 4. Purchase the card whose price most closely matches the result you calculated in Step 2.
Congratulations, you now have access to drivers compiled without the -who-gives-a-fuck-about-artefacts-this-is-worth-150-3dmarks and -crashes-under-edge-cases-but-those-overclocker-kiddies-with-bargain-RAM-won't-know-the-difference flags enabled!
Arguably it misses the point in a slightly different way: it is alleged that the 'summly' acquisition was more or less a sideshow to the purchase, from SRI International(who built the actual summarization technology, and also a little toy called 'Siri' among a variety of other projects, some quite interesting and high powered), of some of the related technology and patents.
Still not something that Yahoo could develop internally(hence the buying of it); but SRI isn't exactly a lean and hungry startup, just an organization with actual serious R&D focus.
Your post sounds exactly like what some faceless prole to incompetent to even manage to be born correctly would write...
After all, totally scientific statistics, complete with numbers and intimidating diagrams, will easily demonstrate how rare and exceptional the talent for entering the world through the correct uterus is. Where most people are already making irresponsible choices even before they've grown a brain stem, this kid was already achieving at or above the 99th percentile as a blastocyst!
I don't care what people do with their data on dropbox. My point was that, as a tool for environments that handle sensitive data dropbox is deeply unsuitable. I can definitely understand why people would want to use it, it sure is handy; but in a situation where you have an obligation to safeguard data pertaining to other people, you are no longer in "what people do with their data" territory, and dropbox is seriously flawed.
convince slashdot that as a waning influence on technology and the internet thats rationed off its core competencies to other players like microsoft, you'll need your own slashdot icon for stories from now on.
Audiences love a good trainwreck, usually more than they love a well-maintained and tediously reliable train.
I read the article and all of the steps. I'm pretty sure I can make a go of it. I just have one question. What's summarization technology?
It's an algorithm for taking a readable piece of text that challenges your attention span, excising chunks of it with the same care and attention to meaning that spambots bring to the task of composing text, and then spitting it onto your smartphone; because 'Mobile' is where the sweet, sweet, VC sugar is.
Not that I'm a skeptic of this fine and worthy invention or anything.
So far, the hype around Yahoo's new CEO has been just that. So far, she's made a teenager a millionaire, turned the website and mail monochrome, and now this.
As much as I'm unimpressed by her tenure so far is "CEO brought in by floundering corporation with dysfunctional management manages dysfunctionally, flounders, N=1" really useful data on "Female CEOs"?
Oh, I don't doubt that they could do a better job(both because it isn't as hot, and because we probably now have access to robots that are even more radiation tolerant than soviet conscripts...); but the sarcophagus is just the most notable example of the fact that actually encapsulating something properly(so that it doesn't just keep bleeding contaminated rainwater forever) gets surprisingly tricky if you have to build the enclosure under radiation constraints, and you can't necessarily just send in a maintenance guy whenever you feel like it.
Given the number of "TEPCO reluctantly announces that local seawater radiation levels suggest that they've got another leak, they just have no idea where" stories, I'm less than 100% optimistic about their ability to encapsulate something for long term storage, though the conditions are certainly more favorable than Chernobyl.
most AC dimmers already pwm so its not that big of a deal for many
The trouble is that the PWM frequencies that work just fine on an electrically-heated-more-or-less-black-body with nontrivial thermal mass aren't likely to be nearly as pleasing on an LED with nearly instantaneous on/off(plus, the LED never actually sees the AC, or it'd be a friode in seconds, so PWM just means that the power supply gets a nastier input to deal with).
Hardly insurmountable, with an appropriate AC PSU; but not automatic.
When people say 'dim' they usually mean 'are compatible with my AC dimmer hardware designed to dim incandescents'. Given that any LED lamp designed to drop into an AC socket will need a reasonably sophisticated power supply(at least if it wants to actually be efficient, not catch fire, and not make the UL cry...), so the marginal cost of a slightly more sophisticated power supply that watches the AC side for 'dimming' behaviors and PWMs the DC side probably wouldn't be huge. However, such units are indeed less common, much as with CCFLs, which can be made to be dimmable with legacy AC dimmer gear; but cannot be relied upon to necessarily be dimmable, unless they specifically say so and aren't lying about it.
That actually did figure into common cold war protocols for dealing with contaminated food and water sources: prioritize less-contaminated ones for the young(both because they are of greater economic use, and because they have more time to accrue chronic radiation damage) and leave the more contaminated stuff to the old people...
Plus, an excellent reason not to take the kids to visit that old relative you never liked much anyway!
If that's the criterion, we might as well just order a bunch of Glock 'particle beam therapy' gear; because the patient is just going to die sooner or later anyway, so it might as well be cheap...
It would be interesting to see how that would work for them: dropbox is a total raging clusterfuck for anything that you actually need to keep secure(I once caught a user storing fucking children's medical records on a personal dropbox account. That was not a fun chat for anybody involved...); but it's hard to deny that the consumer-derived 'cloud sharing' stuff frequently beats the IT department on usability and convenience.
If I were BitTorrent, inc. a corporate play would certainly seem sensible(not too much additional development cost on top of what they already have now, reasonable argument about why they are better than dropbox and clones(more secure, plus bittorrent clients are capable of intelligently transferring from WAN, LAN, or both, so most of the chatter would stay internal)); but I'd be a trifle nervous in the mid term about what Microsoft might do.
They've been surprisingly lousy at actually exposing it in a user-friendly and well known way(see also, Volume Shadow Copy vs. Time Machine, the former being older and arguably technologically superior, the latter being kind of a janky hack; but actually useful for the relatively tech-ignorant); but Microsoft has BITS and BranchCache already written and probably liberally supplied with group policy hooks and whatnot.
Any actual competition, in the near term, would probably come from the MS consumer line, with 'Skydrive', because Microsoft's track record on turning potentially-interesting-but-enterprisey technologies into consumer goods isn't so hot, much less doing so fast; but they've actually done some work on a very similar class of problems, and do have the technology available, just not terribly visible.
Please, do expound as to why your stated fact is important here.
Well, it does mean that they aren't 'cured', and probably places a somewhat uncomfortable upper-probable-bound on how long it will take for the tumors to rally and start expanding again. That's a less than optimal outcome.
On the plus side, there can be a real difference between "Yup, totally fucked, maybe 6 weeks?" and "Yup, totally fucked, 18-20 months, most likely."(especially if the treatment can be made not-terribly-debilitating)
I assume since they are covered in radioactive anti-bodies, that they cannot reproduce and would die eventually from the radiation exposure..
Even if they can reproduce, the only risk would be pathogenic(which you would want to be careful about in a sick and potentially immunoncompromised patient; but some bacterium can likely be found that is quite harmless). The bacteria themselves can't produce radioactive atoms, they just incorporated the ones that they were doped with before injection, and their descendants will have to be built largely from atoms that were inside your body to begin with... So, even if they establish a permanent population, every generation will be composed more of background-level atoms and less of the radioactive dopants.
Obviously, an injection of radiation isn't a good thing if it can be avoided; but the dose is fixed at the time of injection, and if the bacteria allow it to be targeted more efficiently, the damage to healthy tissues would be less severe. It sounds rather like a more sophisticated version of the 'radioactive seed' technique used on some localized tumors, where small pellets of (biologically inert, vitrified or coated in some way) radioactive material are injected directly into the tumor, so as to deliver a lethal dose of radiation without spreading throughout the body(as with an injection of soluble isotopes) or damaging tissue in the beampath(as with external radiation beams).
The use of bacteria and antibodies presumably allows targeting tumors that are too small, too numerous, or both, for a surgeon with a microscope and a needle to seed each one manually.
Can't they just encase the plant in concrete/dirt and say fuk it? Seem to remember reading about Chernobyl being dealt with in similarly crude but effective fashion. Sure it would cost a lot to heap up that much rubble but hey, beats sitting on the thing for decades on end attempting to carefully spoon out all the nasties.
The plan at Chernobyl worked so well that we are now constructing a bigger, better, new sarcophagus to enclose the reactor and the current leaky and structurally unsound old sarcophagus...
Land uninhabitable for generations, 40+ years cleanup, trillions in compensation - yeah, I'd say it all went fairly well!
Luckily, there is a solution! When our man Larry Summers was chief economist at the World Bank, he did a little writing...
In this case, we can't really export the pollution(gathering the radioactive particles simply isn't plausible or cost effective); but we can import the population! Other than the carcinogenic fallout, it's a nice piece of real estate. Plenty of people live in places that are much ghastlier, even without fallout. All we have to do is find the wealthiest tenants who still live in a place with higher mortality(eg. from tropical parasites or malnutrition from marginally arable land) and offer them an attractively priced 50 year lease. The new occupants overall mortality goes down slightly, Japan makes some money back, and everyone basks in the warm glow of the human spirit, and gamma radiation.
For the non-techies, I assume that coming, out of the box, with the various tricks that bittorrent clients use to Just Work behind nasty little plastic NAT boxes would be the major advantage. Nothing intrinsic to bittorrent as a protocol; but certainly a side effect of bittorrent's history.
It might also be useful if your sharing scenario involves enough people that the efficiencies of bittorrent come into play. If it's just keeping Host A and Host B synchronized, you aren't going to do much better than break even, at best, with rsync. If your plan involves all two dozen members of your club, or your entire extended family and a tedious-but-HD vacation video, bittorrent starts to look better; but with the advantage that this 'key/encryption' stuff allows you to have a single host serving different folders with different access controls, unlike conventional trackers that are usually 'public' or 'private', with granular control, if any, mostly hacked on.
Aside from the ease of use, though, the amount of benefit you'd see over rsync seems likely to be directly related to how wide your distribution is.
I sure am glad that, unlike crazy neckbeard stuff like bitcoins, Serious Professional economic instruments don't suffer hilariously baseless volatility because some goofy website got hacked...
That would, like, reduce my confidence in the rationality of the market.
Metal-air batteries don't even pretend to be rechargables.
The little ones(most notably the zinc-air coin cells that pharmacies stock, heavily overpriced, in areas where gullible old people with hearing aids might find them) you just throw away.
The bigger ones are either a 'send back to factory' arrangement or a 'the anodes are an FRU' arrangement.
Your milage may vary, I don't doubt that some ghastly short-run cards that was originally bundled with the motherboard it runs in because merely trying to boot with it on the PCI bus caused over half the systems tested during validation to hard lock, or exhibit all sorts of perverse, heavily timing-dependent, behavior exist; but in Noble Theory, you can actually grab a PCI device from the host's physical bus and glom it on to one of the VM's virtual busses(the main nuisance tends to be that you can't separate the features of a PCI device, so playing the 'Which USB ports on the motherboard are on which USB/PCI device?' game is always a nuisance, as can be multi-port NICs and similar.
The one major category of devices with really tepid actually working skills is video cards, at least ones being used as the primary video device(and thus exercising all those legacy modes, the correctness of the VM's BIOS, etc).
A 'brogrammer' is a specific subset of young male programmers generally. Anybody using it as a synonym for 'young, probably unmarried, male programmer' is doing it wrong; but there is a recognizable population(unfortunately) that it fits pretty well.
Unfortunately, keeping substantial lengths of pipe(especially buried pipe in places where you have to fuck up everybody's commute for a week just to dig down and have a look) non-leaky is a hard problem.
If the substance being piped is dangerous enough, people will suck it up and try(I used to live a few blocks from an elementary school. The guys at the local incompetent natural gas supplier always got a whole lot more... responsive... when I started giving the location as "Maybe 50 meters or so from the elementary school, can't miss it!" rather than just giving the street address); but unless you are pandering for the Fremen vote or something, the economics of keeping some water from leaking out of pipes, rather than just getting 50+ years out of them, aren't quite as exciting...
