Who Profits from Security Holes?

Who Profits from Security Holes?: "How bad is this problem? How much junk can get installed on a user's PC by merely visiting a single site? I set out to see for myself -- by visiting a single web page taking advantage of a security hole (in an ordinary fresh copy of Windows XP), and by recording what programs that site caused to be installed on my PC. In the course of my testing, my test PC was brought to a virtual stand-still -- with at least 16 distinct programs installed."

7-in-1 card reade in fedora

FedoraNEWS.ORG: "2004-02-15 Fedora Tips 44: Here's how to get a 8in1 USB card reader to work with Fedora Core 1 - one that uses multiple LUNs for the different media: 1. Add 'max_scsi_luns=6' to the kernel paramaters in /etc/grub.conf 2. Add 'options scsi_mod max_scsi_luns=6' to /etc/modules.conf Reboot so the new kernel options take effect. When you plug in the USB card reader, you can use the right mouse button on the root window to get a popup menu with a submenu 'drives' that contains entries like 'memstick', 'memstick1', 'memstick2', etc. After you picked one of them, it will be mounted and a new icon appears on your desktop. - submitted by Sven Neuhaus"

64 Bit Processors

Here's an overview on 64 bit processors (various sources), more questions than answers: 

 

Intel's EM64T is Intel's true x86_64 initiative. This 3.6GHz Xeon processor is actually the exact same CPU in as the LGA775 Pentium 4F we will see in just a few weeks.

 

AMD's Opteron 150 is the highest performing AMD workstation CPU money can buy. Thus, it is priced around $600 now.  (The nearly identical FX-53 is priced slightly higher). Intel's Xeon 3.6GHz / Pentium 4 3.6F processor is the highest performing Intel workstation CPU money can't buy; although it has shown up in various OEM channels, it really has not hit the market in full force yet.  When it does, we are expected to see it retail for $850.

 

FWIW, I think the Intel version offers hyperthreading, where the AMD chip does not.

 

Some Benchmarks:

Opteron 150 vs. Xeon 3.6 Nocona: http://www.anandtech.com/linux/showdoc.aspx?i=2163&p=1

Athlon 64 vs. Xenon 3.6 Nocona: http://www.anandtech.com/linux/showdoc.aspx?i=2158

 

Processor Cheat Sheet:

http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2118

 

The Dell Precision 670 is available with the aforementioned Nocona: http://www1.us.dell.com/content/products/features.aspx/precn_670?c=us&cs=&l=en&s=bsd&

 

 

Background:

The AMD64 architecture extends the 32-bit x86 architecture (IA-32) by adding 64-bit registers, with full 32-bit and 16-bit compatibility modes for earlier software. Even the 64-bit mode is largely backward-compatible, allowing existing tools targeting x86 (eg. compilers) to be retargeted to AMD64 with minimal effort.  This is in sharp distinction to Intel's competing IA-64 architecture, which makes a complete break from Intel's own x86 architecture.  AMD has released its first generation of AMD64 processors, under the names Athlon 64 and Opteron. The Athlon 64 (codenamed "ClawHammer") is designed for desktop and mobile computers, while the Opteron (codenamed "SledgeHammer") is intended for servers and workstations.

 

IA-64 (Intel Architecture-64) is a 64-bit CPU architecture developed by Intel and Hewlett-Packard for processors such as Itanium. Unlike previous Intel x86 processors, the Itanium is not geared toward high performance execution of the IA-32 (x86) instruction set.  Itanium can switch into 32-bit mode with special jump escape instructions. The IA-32 instructions have been mapped to the Itanium's functional units. However, since the Itanium is built primarily for speed of its EPIC-style instructions, and because it has no out-of-order execution capabilities, IA-32 code executes at a severe performance penalty compared to either the IA-64 mode, or its Pentium line of processors.  

 

Extended Memory 64-bit Technology (EM64T) is an implementation of the AMD64 architecture, an extension to the IA-32 instruction set developed by AMD which adds 64 bit extentions to the x86 architecture.  Intel's first processor to implement the EM64T technology is expected to be a processor codenamed Nocona. The Nocona will eventually become a dual-processor version of the Intel Xeon.  This technology is not compatible with Intel's earlier 64-bit CPU technology, the Itanium processor based on IA-64 technology. It cannot run the same software written for IA-64. EM64T is an extension of the 32-bit x86 or IA-32 instruction set, while IA-64 is a complete rethink from scratch. One of the biggest complaints about IA-64 was that it was not able to run the existing IA-32 software fast enough, since it emulated the older IA-32 instructions rather than directly interpretting them. EM64T shouldn't have such a problem because IA-32 would just be a subset of its own native machine language.

 

Intel tried to keep the existence of EM64T secret for a long time for two reasons. First reason was that it did not want to give its customers mixed signals about the future viability of its Itanium IA-64 processors. However, the success of AMD's Opteron and Athlon 64 processors, based on its AMD64 technology, pretty much meant that Intel had to respond to the competitive threat. Which brings us to the second reason for Intel's secrecy, Intel didn't want to admit that it had to copy from its arch-rival AMD. That's why it gave it the brand name EM64T rather than AMD64, even though they are near identical twins.

 

 

JDK1.4.2 Is available for IA64

JDK1.5beta2 is available for AMD64 (So probably also runs on EM64T)

IntelliJ gets hosed on Fedora, and other 2.6 kernels: If you add jar files to a project, they appear to imported correctly, but then aren't visible, and browsing through them in the package explorer shows unnamed classes. Workaround: Close IntelliJ Edit your idea.lax in the bin directory, find the lax.nl.java.option.additional property, and append -Didea.jars.nocopy=true to the end of arguement list. Then delete the contents of $intellij/system/jars and $intellij/system/caches Restart, and you may need to recreate your project.

NYTimes, February 27, 2004 For Exercise in New York Futility, Push Button By MICHAEL LUO or years, at thousands of New York City intersections, well-worn push buttons have offered harried walkers a rare promise of control over their pedestrian lives. The signs mounted above explained their purpose: To Cross Street Push Button Wait for Walk Signal Dept. of Transportation Millions of dutiful city residents and tourists have pushed them over the years, thinking it would help speed them in their journeys. Many trusting souls might have believed they actually worked. Others, more cynical, might have suspected they were broken but pushed anyway, out of habit, or in the off chance they might bring a walk sign more quickly. As it turns out, the cynics were right. The city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals, even as an unwitting public continued to push on, according to city Department of Transportation officials. More than 2,500 of the 3,250 walk buttons that still exist function essentially as mechanical placebos, city figures show. Any benefit from them is only imagined. "I always push," said RĂ©na, an employee at Long Island College Hospital in Cobble Hill, Brooklyn, who was too embarrassed to give her last name after she pushed a button on Atlantic Avenue and was told the truth. "The sign says push, so I push. I think it works." Most of the buttons scattered through the city, mainly outside of Manhattan, are relics of the 1970's, before computers began tightly choreographing traffic signal patterns on major arteries. They were installed at a time when traffic was much lighter, said Michael Primeggia, deputy commissioner of traffic operations for the city's Transportation Department. The first "semi-actuated signal," as they are called by traffic engineers, is believed to have appeared in the city in 1964, a brainstorm of the legendary traffic commissioner, Henry Barnes, the inventor of the "Barnes Dance," the traffic system that stops all vehicles in the intersection and allows pedestrians to cross in every direction at the same time. Barnes was also instrumental in completing the one-way conversion of major avenues in New York. Typically, they were positioned at intersections of a major thoroughfare and a minor street. The major road would have a green light until someone pressed the button or a sensor in the roadway detected a car on the minor street. Then, after 90 seconds or so, the light would change. The goal, Mr. Primeggia said, was to make traffic flow on the major artery more efficient. The buttons made sense when traffic was generally minimal on the minor street. But as traffic grew steadily, their existence became imperiled. In 1975, about 750,000 cars entered Manhattan daily; this past holiday season, there were more than 1.1 million. The other boroughs have gone through similar growth, Mr. Primeggia said. As even minor streets became congested, the need for the semi-actuated signal largely disappeared, because they were constantly being tripped anyway by cars rolling up to the intersection. Many walk buttons also interfered with the computer-programmed coordination of lights that is now the rule in the city to facilitate traffic flow. By the late 1980's, most of the buttons had been deactivated, their steel exteriors masking the lie within. But city officials say they do not remember ever publishing an obituary, and the white and black signs stayed up, many of them looking as new and official as ever. "I don't always push, but I do it in the off-chance that I might save two seconds," said Joanne Downes, 63, a retired nursing professor, after pushing a broken button to cross the West Side Highway from Chelsea Piers on West 23rd Street yesterday morning. "I have guessed that they don't work, but why are they there?" There are 750 locations where the buttons actually do work, Mr. Primeggia said. Some of them have been installed more recently, while others are holdovers from two decades ago. The working buttons are only at intersections where the walk signal will never come unless the button is pushed or a car trips the sensor, Mr. Primeggia said. He cited two examples, one at Hicks and Summitt Streets in Brooklyn and the other on Flatbush Avenue just south of the Belt Parkway exit ramp. But other working push buttons are hard to find. A random survey of more than 30 intersections in Brooklyn, Queens and Manhattan found one, at Marathon Parkway and 51st Avenue in Little Neck, Queens, that worked. At $300 or $400 per intersection, it would cost about $1 million to remove the disconnected mechanisms, Mr. Primeggia said. About 500 have been removed during the course of major reconstruction projects. But city officials over the years decided it was not worth the cost for the rest, given other needs like rebuilding roads or installing new traffic signals. "We think of this from time to time," Mr. Primeggia said. "But there's always a better need for the money." And in the bigger scheme of things, he said, it doesn't really matter if people push a working button. "The public is going to get the walk signal regardless," he said. "I guess that's the point. There's no harm in having it at the locations." Many veteran New Yorkers have long learned to ignore them. They have never made sense, said Maryam Ceesay, 24, standing at a downtown Brooklyn push-button intersection.
