Nmap 5.20 Released 36

ruphus13 writes "Nmap has a new release out, and it's a major one. It includes a GUI front-end called Zenmap, and, according to the post, 'Network admins will no doubt be excited to learn that Nmap is now ready to identify Snow Leopard systems, Android Linux smartphones, and Chumbies, among other OSes that Nmap can now identify. This release also brings an additional 31 Nmap Scripting Engine scripts, bringing the total collection up to 80 pre-written scripts for Nmap. The scripts include X11 access checks to see if X.org on a system allows remote access, a script to retrieve and print an SSL certificate, and a script designed to see whether a host is serving malware. Nmap also comes with netcat and Ndiff. Source code and binaries are available from the Nmap site, including RPMs for x86 and x86_64 systems, and binaries for Windows and Mac OS X. '"

Widespread Attacks Exploit Newly-Patched IE Bug 141

itwbennett writes "The first widespread attack to leverage the Internet Explorer flaw that Microsoft patched in an emergency update Thursday morning has surfaced. By midday Thursday Symantec had spotted hundreds of Web sites that hosted the attack code. The attack installs a Trojan horse program that is able to bypass some security products and then give hackers access to the system, said Joshua Talbot, a security intelligence manager with Symantec. Once it has infected a PC, the Trojan sends a notification e-mail to the attackers, using a US-based, free e-mail service that Symantec declined to name." Relatedly, reader N!NJA was among several to point out that Microsoft has apparently been aware of this flaw since September.

Heat Engines Shrunk By Seven Orders of Magnitude 168

KentuckyFC writes "The vast majority of motors that power our planes, trains, and automobiles are heat engines. They rely on the rapid expansion of gas as it heats up to generate movement. But attempts to shrink them by any significant amount have mostly ended in failure. Today, the smallest heat engines have a volume of some 10^7 cubic micrometers. Now group of Dutch engineers has built a heat engine that is seven orders of magnitude smaller than this. The engine consists of a piezoelectric bar that expands and contracts in the normal piezoelectric way. However it also heats up and cools at the same time causing a thermal expansion and contraction, which lags the piezoelectric displacement. By carefully choosing the frequency of the driving AC current, the Dutch team found a resonant effect in which the thermal expansion and contraction amplifies the mechanical motion, making it a true heat engine. Operating the thermodynamic cycle in reverse turns the device into a heat pump or refrigerator. The total volume of the device is just 0.5 cubic micrometres."

Facebook's Zuckerberg Says Forget Privacy 415

judgecorp writes "Privacy is no longer a social norm, according to the founder of Facebook, Mark Zuckerberg. Speaking at the Crunchie awards in San Francisco, the entrepreneur said that expectations had changed, and people now default to sharing online, not privacy. It's all right for him, but does he mean it's ok for bodies like the UK government to monitor all citizens' Internet use?"

New "Wet Computer" To Mimic Neurons In the Brain 132

A new type of "wet computer" that mimics the actions of neurons in the brain is slated to be built thanks to a €1.8M EU emerging technologies program. The goal of the project is to explore new computing environments rather than to build a computer that surpasses current performance of conventional computers. "The group's approach hinges on two critical ideas. First, individual 'cells' are surrounded by a wall made up of so-called lipids that spontaneously encapsulate the liquid innards of the cell. Recent work has shown that when two such lipid layers encounter each other as the cells come into contact, a protein can form a passage between them, allowing chemical signaling molecules to pass. Second, the cells' interiors will play host to what is known as a Belousov-Zhabotinsky or B-Z chemical reaction. Simply put, reactions of this type can be initiated by changing the concentration of the element bromine by a certain threshold amount."

Asus Promises 12-Hour Battery Life In New High-End Laptop 190

Asus' new high-end laptop could finally be the traveler's best accoutrement, touting twelve-hour battery life thanks to intelligent, second-by-second switching between the two GPUs and automatic, on-the-fly re-clocking of the Intel Core i7 CPU. All this also comes in with a price tag of just over $1,000. "ASUS's solution is different because it's user-transparent; even a novice user will get the fullest possible benefit because the laptop itself is deciding when to switch. The same principle applies to the dynamic CPU clocking. ASUS includes a desktop widget to track CPU clock speed. While using the UL80JT, I could see it moving up and down with what I did; up with program openings and CPU-intensive processes, and way down at idle. Between the GPU switching, dynamic clocking, and ASUS's other power management features, the UL80JT manages to consume less than half as much power as the unibody Macbook while browsing."

Firm To Release Database, Web Server 0-Days 220

krebsonsecurity writes "January promises to be a busy month for Web server and database administrators alike: A security research firm in Russia says it plans to release information about a slew of previously undocumented vulnerabilities in several widely-used commercial software products, including MySQL, Tivoli, IBM DB2, Sun Directory, and a host of others, writes krebsonsecurity.com. From the blog: 'After working with the vendors long enough, we've come to conclusion that, to put it simply, it is a waste of time. Now, we do not contact with vendors and do not support so-called "responsible disclosure" policy,' Legerov said."

Futuristic Sex Robots Now Just "Sex Robots" 602

High-C writes "With apologies to Futuristic Sex Robotz, the future is here, and her name is Roxxxy. Truecompanion.com has revealed their answer to the Real Doll, and it looks nice. The site is short on details, pictures, pricing info, but wow." NOTE: some of the above links are not work-safe, for many values of work. I stopped by this exhibit today at the AVN Expo (not officially a part of CES, but by curious coincidence scheduled to coincide; the old saw that porn drives tech isn't without merit). Roxxxy, though, was rather unsexily posed on a couch, not moving a bit — downright creepy, in fact.

Why Programmers Need To Learn Statistics 572

David Gerard writes "Zed Shaw writes an impassioned plea to programmers: Programmers Need To Learn Statistics Or I Will Kill Them All. Quoting: 'I go insane when I hear programmers talking about statistics like they know s*** when it's clearly obvious they do not. I've been studying it for years and years and still don't think I know anything. ... I have taken a bunch of math classes, studied statistics in grad school, learned the R language, and read tons of books on the subject. Despite all of this I'm not at all confident in my understanding of such a vast topic. What I can do is apply the techniques to common problems I encounter at work. My favorite problem to attack with the statistics wolverine is performance measurement and tuning. All of this leads to a curse since none of my colleagues have any clue about what they don't understand. I'll propose a measurement technique and they'll scoff at it. I try to show them how to properly graph a run chart and they're indignant. I question their metrics and they try to back it up with lame attempts at statistical reasoning. I really can't blame them since they were probably told in college that logic and reason are superior to evidence and observation.'"

Samsung Develops a Transparent OLED Laptop Screen 148

Dyne09 writes "The Design blog has posted an entry on Samsung's new laptop with a transparent OLED screen. The photos show a dark-tinted and dimly-lit screen that is fully see-through. While the utility of a see-through laptop probably isn't that high for the average user, several medical and industrial industries could greatly augment design work or frame 3-D models over real life in real-time."

OMNI Magazine Remembered 131

An anonymous reader noted that Slate is doing a bit of a retrospective on OMNI. If you're anything like me, reading it was a treat. At home I suffered through Popular Mechanics, but OMNI was what I wished I had. There's many interesting things in the article, like the fact that OMNI is the place where William Gibson first coined the term "Cyberspace."

Core i5 and i3 CPUs With On-Chip GPUs Launched 235

MojoKid writes "Intel has officially launched their new Core i5 and Core i3 lineup of Arrandale and Clarkdale processors today, for mobile and desktop platforms respectively. Like Intel's recent release of the Pinetrail platform for netbooks, new Arrandale and Clarkdale processors combine both an integrated memory controller (DDR3) and GPU (graphics processor) on the same package as the main processor. Though it's not a monolithic device, but is built upon multi-chip module packaging, it does allow these primary functional blocks to coexist in a single chip footprint or socket. In addition, Intel beefed up their graphics core and it appears that the new Intel GMA HD integrated graphics engine offers solid HD video performance and even a bit of light gaming capability."

Thorium, the Next Nuclear Fuel? 710

mrshermanoaks writes "When the choices for developing nuclear energy were being made, we went with uranium because it had the byproduct of producing plutonium that could be weaponized. But thorium is safer and easier to work with, and may cause a lot fewer headaches. 'It's abundant — the US has at least 175,000 tons of the stuff — and doesn't require costly processing. It is also extraordinarily efficient as a nuclear fuel. As it decays in a reactor core, its byproducts produce more neutrons per collision than conventional fuel. The more neutrons per collision, the more energy generated, the less total fuel consumed, and the less radioactive nastiness left behind. Even better, Weinberg realized that you could use thorium in an entirely new kind of reactor, one that would have zero risk of meltdown. The design is based on the lab's finding that thorium dissolves in hot liquid fluoride salts. This fission soup is poured into tubes in the core of the reactor, where the nuclear chain reaction — the billiard balls colliding — happens. The system makes the reactor self-regulating: When the soup gets too hot it expands and flows out of the tubes — slowing fission and eliminating the possibility of another Chernobyl. Any actinide can work in this method, but thorium is particularly well suited because it is so efficient at the high temperatures at which fission occurs in the soup.' So why are we not building these reactors?"
