Yeah, I came away with a similar impression: Bosworth, or at least those touting his speech, are ignoring the truely significant differences between web searching and DB queries in these areas
performance...he talks about scaling as if DB size and number of users were the only dimensions of scaling issues...time is an important dimension as well, espcially when you speak of concurrent update attempts.
databases support writing, not just searching, records and that entails levels of privelege beyond what the web easily supports.
API: SQL is an api and supports programmatic use of databases. THAT CANNOT BE SLOPPY Users have the intelligence to sort out relevant responses to a query, programs do not and the precision of a SQL response from a properly organized database IS mandatory. Can you imagine a "sloppy" access of your medical records that left a doctor with picture of your health history that was actually a composite of several persons who matched your search parameters to tolerances "close enough" for search engines? Sheesh!
Current RDB and SQL are just barely adequate in supporting a few levels of access privelege...ultimately access authorization is damn hard to distribute in the way Bosworth seems to pine for
WaPo has a copy of the Cisco/ISS restraining order against Lynn:
In the order, which was jointly filed by ISS and Cisco, Lynn is said to have illegally reverse-engineered Cisco source code and that he stands to profit from this research. A copy of the document, obtained by washingtonpost.com, reads: "Cisco believes that Lynn is also disclosing ISS and Cisco proprietary information outside of the context of a formal presentation as well."
Just what did all these parties think Black Hat Con was about anyway, if not to expose vulnerabilities?
In one china, poor farmers live with their chickens and pigs and ignorantly breed new influenza strains for the world to deal with.
In another china, they are executing a global warming nightmare with filthy old coal fired steelmaking thats been outlawed for decades even by republican administrations in the US. In another china, young technologically savvy workers and administrators make out OK in the nascent market economy and expect to drive a car as none of their parents did with gasoline from where? In yet another china, vast and poorly paid labor pools help the nation rack up huge trade surplusses which the government cashes in for infrastructure, housing, office buildings and universities where science for both peaceful and military purposes is carried out. This latter china is of concern in TFA. But all the china's will have to settle accounts as one. Like us, they will run out of gas before they run out of ideas and long before they run out of pride. I for one, avoid walmart just so I DON'T contribute more that I absolutely have to to the cash flow funding that latter china.
you need not hide , AC. look around: most of us are with you on this commenter's wrongheadedness. the mods,however ought to be careful and less biased readers...alas, the mods must be crazy!
silly coward, you are whistling past the graveyard, as they say. Other than chauvanism what informs your opinion? Korea now has cloning achievements to match anything done in the religion-hobbled US. Wake up!
a clear description of hydrogen fuel cell shows that hydrogen and oxygen must be separated. The direction and strength of the current depends entirely on the relative purity of the gases [mixed gasses would "short circuit" the cell] and which side the cell is loaded with which gas.
"....O2 seems to present in the sulfur tank. I don't know how much is present...." You have a point here...we are pretty much just going on pictures here and the arrows seem to indicate that O2 is both emitted and consumed in roughly equal amounts. Its not clear that oxygen is a byproduct in the sulfate stage. Numbers would be helpful.
I'm not always that condescending and I regret the tone of my reply.
I'm not a chem. engineer but what little I know about fuel cells leads me to expect that it IS necessary to separate the hydrogen from the oxygen...the electron exchange in presence of of catalysts must take place across a membrane or barrier in order for a current/voltage to arise. What is less clear to me is whether the UW process can tolerate oxygen as a contaminent in the H2 fed into the reaction vessel.
and no, I have no clue how you'd separate the mixed gases. I do know that H2 and O2 have very distinct absorbtion frequencies...perhaps that would make it possible to draw the mixed gasses through a maser cavity under very low pressure causing one of the gasses to dissociate to atomic or even ionzied state and then use MHD to separate the charged from uncharged gas. This would be somewhat like a mass spectrometer [which would provide separation but at enormous cost]. I won't go any farther out on this limb: seems it would be a total energy loser even if it did work.
I remember what a big scandal it was when "Murry the K" got caught basically taking bribes from the labels to give their latest single some air time. that was when the term "payola" was invented.
whats really changed? Radio was the outlet, the only way a song got much exposure. That put the station in the power broker spot and DJ's had
more control back then perhaps. Air time was a seller's market and buyers
bid it up all sorts of ways. Now there are many channnels for promotion beside radio, and especially, there is P2P. The calculation the record label makes in budgeting for a decent return on a recording is quite different. In addition to bribes to station managers, they have to ponder how much of the product they should allow to leak into the prospective market via legal and illegal file sharing, whether to make a music video, look for a movie where the song fits in the sound track, and if the artist is sexy enough, whether to put him/her on tour. It gets complicated and I'd bet fewer producers are making huge profits and finding it harder and harder to have the next "Beatles" on their label.
What surprises me is that, with all those options, Sony would bother with the bribery at all....or, now that I think about it, perhaps Sony is only coming clean now for PR sake because their real reason to stop payola is that it no longer buys much record sales.
NREL, Stanford, meet U. Wisconsin. U. Wisconsin, meet Stanford and NREL. if you guys play nice together and don't play politics, maybe my grandchildren won't be bicycling to the library to read about an age when combustible hydrocarbon liquids were used to run selfpropelled vehicles.
I'd love to know exactly how credible the UW claims are. To whet the appetite of chemically knowledgible/.ers who might otherwise not have seen this article, their energy bottom line:
About 67 percent of the energy required to make ethanol is consumed in fermenting and distilling corn. As a result, ethanol production creates 1.1 units of energy for every unit of energy consumed. In the UW-Madison process, the desired alkanes spontaneously separate from water. No additional heating or distillation is required. The result is the creation of 2.2 units of energy for every unit of energy consumed in energy production.
I was so tempted to try posting the UW result when it came out but/. can't get forty comments on biology topics in 2 hours. [and they get over 900 on ethanol...go figure!] The eds like stories that get hundreds, not tens of responses. Is there a/. equivilent for sustainablity nerds?
RTFA.
they have two methods, one cycles the organism in a soup between two fermentation tanks, one enriched in sulfur the other deficient in sulfur. They are trying to engineer an algae that has a form of hydrogenase that does not break down immediately in the presence the oxygen it produces and they have are also tweaking the genes of the algae so it will produce the gas in one tank and get shuttled to the other tank, where the different nutrients allow it to recover for another go-round. The bug should work anaerobically in the sulfate tank producing hydrogen gas there, then photosynthetically in the unsulfered tank, recharging. Net oxygen production occurs in the photosynthetic phase, a separate tank from hydrogen production: the O2 and the H2 are never mixed to begin with Well, thats the theory anyway...can't you read?
data was collected from volunteers. The act of volunteering implies pretty strongly that they knew and consented beforehand to have their activity monitored and recorded. It is reasonable to assume that persons making such consent [a] are not engaged in any activity they don't want others to know about and/or [b] will refrain during the data gathering period from engaging in activities they don't want generally known. [e.g. the prof who is having a fling with a coed is not going to use his cell phone for setting up lunch dates while his phone use is recorded.] [yes nerds, people do stuff like that, its the "stuff that matters" when you are not a nerd!]
My point? The least predictable [but in some cases quite significant] activity was systematically left out of the data set...so yes its painting a picture of predictable behaviour but not a very realistic picture.
Telus has made the strongest possible case they can for their action: protecting the privacy of individuals who are named/blamed by the offending website. It's still bullshit for them to block access if they don't host the site. Again, just my opion: its not an ISP's job to say what constitutes harming exposure or invasion of privacy...that is why Canadians have courts, laws and police.
Canadian legal concepts around freedom of speech....how different from US 1st amendment
the exetent to which web access is like radio or newpaper where the owner of the media is the one who's freedom of speech is tested when they wish to control what information/opinion is conveyed by their media as opposed to soapboxes and posters on a public wall where the freedom of speech of the party with the [not necessarily popular] opinion/information is tested.
I'd find in favor of the employer blocking a site they hosted but IMHO its an unwarranted censorship for them to keep their own customers from finding information just because they, the ISP, do not and would not choose to host that page or site.
a few years back the ecologists and biologist were very worried about a spate of population declines and muliple cases of hideous mutations in frog species. we had lots of 3-legged frogs in places around the US when the French were the only ones who'd want that. UV from depleted ozone, pesticide polution...all sorts of theories were advanced. Turns out ONE of the problems was desease or parasites introduced into ponds and rivers when the Forest Service and restocked fisheries with trout they'd farmed in tanks.
It shouldn't spiral! interesting you noticed that it is a spiral. As a teaching tool, it ought to be concentric rings, not a spiral, as that would more clearly communicate the idea that not all energy levels are possible and that atomic "shells" exist as a consequence of this quantization requirement.
assuming all the other data a typical periodic table [poster sized or wall chart] crams in to each element's box can be added to this depiction.
Don't you see that all the orbital or shells [that make for a confusing notation that chemists painfully memorize and physicists gleefully re-explain with Schroedinger's wave equations that mean nothing to most of us] are made much more intuitive in this representation? This new chart can still give those with no education in atomic physics the intuitive recognition of "what should come next", "what's missing" and "what will weigh more" as the old chart has. Consider that chem teachers are are told to regard as advanced any student who understands this notation[search for "Level 3, the student is able to...". Or considered how labored even a chem101 treatment of this material is.
One thing I will concede: Pauling's notion of "electronegativity", so useful to chemists, was clearly related to location of an element on the standard periodic table [changing most strongly as you traversed diagonally from lower left to upper right]...its not so clear here.
if they sued Mr. Lee. Despite the prevalence of non-compete clauses most developers and researchers sign upon employment, lawyers will tell, [as mine has told me], that former employers have very weak cases when they try to curtail the freedom of a former employee to make his or her living.
Slashdot Mirror
yeah, I had "troll" coming for that remark. I keep forgetting that some of us have no sense of humor whatsoever.
which service to I kill to make ie go away?
Just what did all these parties think Black Hat Con was about anyway, if not to expose vulnerabilities?
, hours before anyone else would publish...they just didn't have the whole story.
which is probably why slashdot didn't post my version yesterday.

But, U.Wisconsin chem researchers have a chemical [heat and catalysts, not bio-reactors] process that make biodiesel out of cellulose, which is 3/4 of dried plant material by weight . This means most of what farms [and cities too, if you count leaves and grass clippings] burn, bury or compost could be feedstock. Study the diagram...the UW process needs an H2 in-feed [it hydrogenates carbon chains to make the diesel, the H2 shown leaving the reactor is a fraction of what goes in]. So their process would be an energy winner if only a source of H2 that does not consume fossil fuel were available .
