Plug-In Hybrids Aren't Coming, They're Here
Wired is running a story about the small but vocal, and growing, number of people who aren't waiting for automakers to deliver plug-in hybrids. They're shelling out big money to have already thrifty cars converted into full-on plug-in hybrids capable of triple-digit fuel economy. "The conversions aren't cheap, and top-of-the-line kits with lithium-ion batteries can set you back as much as $35,000. Even a kit with lead-acid batteries — the type under the hood of the car you drive now — starts at five grand. That explains why most converted plug-ins are in the motor pools of places like Southern California Edison... No more than 150 or so belong to people like [extreme skiing champion Alison] Gannett, who had her $30,000 Ford Escape converted in December. Yes, that's right. The conversion cost more than the truck."

"Nie można przełamać czegoś, co nie istnieje" - polski wyrok w sprawie SQL Injection
Sąd Rejonowy w Głogowie VI Wydział Grodzki w dniu 11 sierpnia 2008 r. wydał ważny wyrok w sprawie mężczyzny oskarżonego o to, że używając komputerów nie będąc do tego uprawnionym, po przełamaniu elektronicznego zabezpieczenia, serwera pewnej firmy, uzyskał informacje - dane osobowe - dla niego nie przeznaczone, działając tym samym na szkodę tej firmy, a więc w sprawie oskarżonego o czyn z art. 267 §1 kodeksu karnego. Sąd wyrokiem (sygn. akt VI K 849/07) uniewinnił oskarżonego od zarzutu, nakazał zwrócić oskarżonemu dowody rzeczowe wymienione w wykazie dowodów, a na podstawie art. 632 pkt 2 KPK orzekł, że koszty procesu ma ponieść Skarb Państwa. Wyrok jest prawomocny. To bardzo ważne rozstrzygnięcie (sygnalizowałem, że opublikuję informację na ten temat przy tekście Pochwalił się internetowi, pochwali się wnukom), a dotyczy m.in. granic możliwości przeprowadzania "audytu bezpieczeństwa" serwisów internetowych, a także spraw związanych z tzw. SQL Injection.

No Naked Black Holes
Science News reports on a paper to be published in Physical Review Letters in which an international team of researchers describes their computer simulation of the most violent collision imaginable: two black holes colliding head-on at nearly light-speed. Even in this extreme scenario, Roger Penrose's weak cosmic censorship hypothesis seems to hold — the resulting black hole (after the gravitational waves have died down) retains its event horizon. "Mathematically, 'naked' singularities, or those without event horizons, can exist, but physicists wouldn't know what to make of them. All known mechanisms for the formation of singularities also create an event horizon, and Penrose conjectured that there must be some physical principle — a 'cosmic censor' — that forbids singularity nakedness..."

Linux Turns 17 Today
Meshach writes "Over at the Linux Journal, Doc Searles is noting that today marks 17 years since Linus posted to Usenet, starting Linux (post). As a Linux user at work and at home I say, thanks Linus!" The anniversary is also featured on the top page of the Encyclopedia Britannica.

Jobs Rumor Debacle Besmirches Citizen Journalism
On Friday someone posted a false rumor that Steve Jobs had suffered a heart attack on CNN's unverified citizen journalism site, iReport. Apple's stock price went vertical, losing 9% before Apple stepped in and denied the rumor; the stock then recovered most of its loss. The SEC is investigating. PCWorld looks at the hit taken by citizen journalism as a result of this incident. "[The] increasingly blurred line between journalism and rumor is a serious concern for Al Tompkins, the broadcast/online group leader at The Poynter Institute — a specialized school for journalists of all media forms. 'How could you possibly allow just anybody to post just anything under your [CNN] label unless you have blazing billboards that say, "None of this has been verified, we've not looked at any of this, we have no idea if this is true?"' he asks."

Mimicking Electric Eel Cells
An anonymous reader writes "A team of US researchers has asked the following question in the new field of systems biology: 'Do we understand how a cell produces electricity well enough to design one, and to optimize that design?' They believe it should be possible to build artificial cells replicating the electrical behavior of electric eel cells. In fact, such artificial cells could deliver better performance — as much as 40% more energy than real eel cells, a computer model suggests. They could be used to power medical implants and other small devices."

A Wikipedia Conspiracy and the Wall Street Meltdown
PatrickByrne writes "This is The Register's world-class investigative piece concerning one aspect of the meltdown on Wall Street ('naked short selling') and how the criminals engaged a journalist to distort Wikipedia to confuse the discourse. The article explicitly and formally accuses a well-known US financial journalist, Gary Weiss, of lying about his efforts to distort a Wikipedia page under assumed names, and accuses the Powers That Be in Wikipedia (right up to and including Jimbo Wales) of complicity in protecting Weiss. This is not another story about a 15-year-old farm kid in Iowa pretending to be a professor. This is like the worst Chomskian view of Elites manipulating mass opinion. But it is all documented." We discussed the alleged Wikipedia manipulation when The Register first wrote about it last December. The submitter is the CEO of Overstock.com and a major player in this drama from the beginning.

Encrypted Images Vulnerable To New Attack
rifles only writes "A German techie has found a remarkably simple way to discern some of the content of encrypted volumes containing images. The encrypted images don't reveal themselves totally, but in many cases do let an attacker see the outline of a high-contrast image. The attack works regardless of the encryption algorithm used (the widely-used AES for instance), and affects all utilities that use single symmetric keys. More significant to police around the world struggling with criminal and terrorist use of encryption, the attack also breaks the ability of users to 'hide' separate encrypted volumes inside already encrypted volumes, whose existence can now for the first time be revealed." The discoverer of this attack works for a company making full-disk encryption software; their product, TurboCrypt, has already been enhanced to defeat the attack. Other on-the-fly encryption products will probably be similarly enhanced, as the discoverer asserts: "To our knowledge is the described method free of patents and the author can confirm that he hasn't applied for protection."

Birth of a New African Ocean
Khemisty writes "Formation of an ocean is a rare event, one no scientist has ever witnessed. Yet this geophysical nativity is unfolding today in one of the hottest and most inhospitable corners of the globe. Africa is splitting apart at the seams. From the southern tip of the Red Sea southward through Eritrea, Ethiopia, Kenya, Tanzania, and Mozambique, the continent is coming unstitched along a zone called the East African Rift." This stretching of the earth's crust has been going on for 20 million years, and within another 10 million the Red Sea will have broken through to create a new sea.

Dispelling Myths About Geomagnetic Reversal
UniverseToday has an interesting look at geomagnetic reversal, the process in which the Earth's magnetic poles trade places. The article cites known trends and recent studies to debunk doomsday myths and unsubstantiated claims about the process. One such study is attempting to model the earth's core with a 26-ton ball of molten metal. Another recently found evidence that the Earth has a second, weaker magnetic field. "We do know that this magnetic pole flip-flop has occurred many times in the last few million years; the last occurred 780,000 years ago according to ferromagnetic sediment. A few scaremongering articles have said geomagnetic reversal occurs with 'clockwork regularity' — this is simply not true."
