The programmers know our shipping password because they've had to ship things before and the administrative assistants know our printer passwords, for instance. Are there any easy ways to manage these types of passwords securely? If an employee leaves, we have to change all of the passwords (particularly for the places that do not allow multiple delegate user accounts) and simultaneously tell everyone the new password, which is tedious and error prone, at best. What are some methods that have worked in your small companies?
An anonymous reader writes: A California inventor is developing a new compact and highly efficient engine — the Massive Yet Tiny (MYT) engine — that promises high power output with a very high power to weight ratio (20:1). The inventor, Raphial Morgado, recently won first prize in the 2005 Emhart-NASA Tech Briefs Design Contest for his work on the engine.
The engine moves pistons on different rotors relative to each other to form combustion chambers of variable volume in a toroidal cylinder. The pistons move in stepwise fashion, with the pistons on one rotor travelling a predetermined distance while the pistons on the other rotor remain substantially stationary.
Fuel is drawn into a chamber as one of the pistons defining the chamber moves away from the other, and then compressed as the second piston moves toward the first. Myt2 The cycles of the MYT engine. Click to enlarge.
Combustion of the fuel drives the first piston away from the second, and the spent gases are then expelled from the chamber by the second piston moving again toward the first. An output shaft is connected to the rotors in such manner that the shaft rotates continuously while the rotors and pistons move in their stepwise fashion.
The engine fires 16 times on one revolution of the crankshaft, 32 times on two. By comparison, a standard V8 fires four times per crankshaft revolution — one-quarter the number of the MYT. Angel Labs, the company developing the engine, calculates the equivalent displacement of the MYT as 848 cubic inches (13.9 liters), with a 3-inch bore and a 3.75-inch stroke. The company further calculates that the 14" x 14", 150-pound prototype could produce power in excess of 3,000 hp.
[The 3,000 hp rating] is conservatively estimated from 850 CID. A conventional engine can produce 4 hp per CID (when turbo charged). Four times 850 [the equivalent displacement] is more than 3,000. Our data of air motoring (800 lb.ft. of torque from 150 psi of compressed air) extrapolates to more than 4,000 lb.ft. of torque when fuel is ignited, exceeding our conservative estimate.

The design is also modular. Additional MYT units can be connected by removing the rear cover of the engine and connecting another ME chamber assembly. With a dual-assembly configuration, the engine becomes a "64-cylinder" engine with 1,695 cubic inches displacement (27.8 liters), raising the power-to-weight ratio up to a projected 40:1.
The engine uses only about 20% of the number of parts normally found in a reciprocating internal combustion engine, and only 12 of the MYT parts are moving parts, reducing friction and parasitic losses.
Unlike a reciprocating combustion engine, the MYT engine permits a piston dwell at the equivalent of Top Dead Center (TDC) — the starting point for combustion. The current prototype is set for a piston dwell of approximately 12 degrees of the crankshaft rotation. By adding in that delay under combustion before permitting the power stroke, the MYT burns a greater percentage of the fuel and air mixture in the combustion chamber, resulting in a more complete combustion.
All we know is that 12-degrees dwell at the TDC, which no other engine can do, will burn all the fuels completely. Therefore, we expect very clean emissions.

Other features of the engine include:
The ability to support a compression ratio as high as 70:1.
No valves. The MYT uses open ports with no restriction. Airflow action is one way.
The entire engine acts as a heat sink and a radiator. It is both air and oil cooled.
There is no thrust loading on piston skirts.
Pistons do not touch the cylinder walls, only the rings do.
Pistons travel only the same direction. No reciprocation, only stop and go.
There are no cylinder heads, no cam shaft, no valves (the ME is equivalent to the bottom end of a reciprocating engine).
Intake compression and power stroke and exhaust stroke events are happening all at the same time, so there are no load strokes.
The MYT engine is not the first implementation of rotating pistons in a toroidal cylinder — the 1968 Tschudi engine is very similar in concept. (A newer derivative is by Hoose, 2005.) The key to the MYT engine is its timing mechanism.
The stop and go actions can be generated in many different ways, but you can not have active locking mechanism, because it will break under repeated stress. It took Raphial, who usually can invent in a couple of hours per invention, more than two years to come up with this invention (he threw away about 10 different ways of implementation.)

Angel Labs is targeting a number of application: autombiles and trucks, pumps and compressors, aviation (helicopter, fixed wing and UAV), and military. Their goal is to license the technology non-exclusively to everyone. According to Jin Kim, Angel Labs is currently in discussions with Lockheed Margin, Boeing, Ford and several smaller potential licensees.

The release will potentially make writing malicious code for both an Apple product and a mobile device irresistible to some attackers.

Think about an installer that allows you to install and uninstall Linux as any other application. An installer that does not require you to burn an ISO, that does not change your partitions, that does not change your bootloader, and still gives you a normal dual-boot setup, with full hardware access. Impossible? Enter Wubi. Wubi sits between a demo and a full installation, bringing you the best of both words. It works like a real installation but it is easy and safe to install and remove like a demo. Wubi was born as an independent (GPL) project, but it will become an official Ubuntu installer in Gutsy. Caveat: it is still in beta.

While Germany's parliament has not held a vote over the proposed law yet or set a date for the vote, Google's Global Privacy councel Peter Fleischer calls the proposal a "heavy blow against the private sphere." The article continues to quote him as follows:
"Many users around the globe make use of this anonymity to defend themselves from spam, or government repression of free speech,"
""If the Web community won't trust us with handling their data with great care, we'll go down in no time." As an emergency measure, he said — rather than change the product — "we would shut off Google Mail in Germany."

For whatever reasons, such as prefer to view and store the videos in mp4.wmv format, and want to play the offline video clips in portable player such as Mobile Phone,PSP and iPod,zune,or simply don't like to view it with FLV Player, then there is a need to convert the.flv video format to another format such as.avi,.mov,.wmv and.mpg..mp4, 3GP,this is a sample of converting youtueb video to play on ipod step by step,
What is FLV?
FLV, or Flash Video, is a preferred file format that is designed for web playback, offering high rates of compression to deliver video over the Internet using Adobe Flash Player (formerly known as Macromedia Flash Player) version 6, 7, 8, or 9. Yet FLV files cannot be played back directly and they must be embedded in an SWF file. The most common approach is to use an SWF file that functions as a media player with screen and playback controls. Notable users of FLV are YouTube, Google Video, Myspace, Metacafe, Dailymotion, iFilm, Music, eVideoShare, StreetFire, etc.
Note: Unlike other conversion tools, Moyea FLV to Video Converter will enable you to convert particular FLV files including On2 vp6 video FLV, Nelly Moser audio FLV into the proper video format for playback on your iPod player without the need to install extra codecs or other additional system or third party components for some functionalities.
Launch Moyea FLV to Video Converter

Not so Indians or Chinese, or Filipinos. Or Cubans or Iraqis come to that. You can get three or four of most of these for what you might have to pay an American. This is why tech firms are keen to ship workers into the States to get them to work for them, rather than some equally-qualified but expensive hamburger-muncher from down the road.
But immigration laws pertaining to the hiring of foreign workers in the States are tight. And firms have to prove that they can't find anyone in their back yard to do the jobs they need to fill, before casting their gaze abroad. This is why U.S. firms hire consultants to publish classified job ads in local U.S. papers, with goal of not finding any applicants. At least that's what a report on the Information Clearing House" alleges. Here, you'll find a nice little video in which immigration attorneys from a firm, Cohen & Grigsby, explain how they help employers post job ads that no-one will apply for so that the firms can then use these in evidence when helping bring in workers from abroad.
"Microsoft, Oracle, Hewlett-Packard, and thousands of other companies are running fake ads in Sunday newspapers across the country each week," it claims. Link to Original Source

mrnomas writes "What's to blame for the declining CD sales? Is it that manufacturers are putting out more and more 'safe' (read: crap) music while independent musicians are releasing online? Is it because iTunes is now the third largest music retailer in the country? Or is it just that CDs are becoming obsolete?" Quoting: "Forbes.com [ran] an article showing that CD sales are expected to be down 20% in 2008 (slightly higher than the 15% drop initially predicted). Why such a drop? What's truly happening is a gradual shift away from physical media to downloadable formats. What this indicates, so far, is that US sales of digital music will be growing at an estimated rate of 28% in 2008, however physical sales will drop even further, resulting in a net overall decline.""
