Comment Only later models (Score 3, Informative) 82

The original PS3 models probably don't suffer from this, as they use on-board flash ram chips to hold the firmware.

Later versions of the PS3 cut out those flash ram chips as a cost-saving measure, in favor of bootstrapping the firmware from the hard drive. These models store the firmware on the drive, and these are the ones that might have this problem.

Comment Further idiotic errors (Score 2, Insightful) 229

Point the first: 1^1020 = 1.

Point the second: 1/1 = 1, which is greater than a trillionth.

Point the third: The cited article calculates 2.55453 X 10^20, and a trillion is 10^12, so the trillionth guess was only off by 8 orders of magnitude, not 1,020 orders, as I thought when I wrote that.

Point the main: I should not try to show off my math on the Internet.

Comment Re:Photon pressure wildly, ludicrously off (Score 1) 229

And while I'm confirming my hand-waving stupidity, I'd like to cite http://cubesat.wikidot.com/opticalflux, which has a quick calculation showing on the order of 2.55453 x 1020 photons.s-1.m-2, so when I cleverly said 'less than a trillionth of that amount', you should read 'less than 1^1020th' of that amount instead.

Fortunately for me, 1^1020 is more than a trillionth, so dividing it out would result in 1/1^1020, which is less than a trillionth. So it kind of works out.

Comment Photon pressure wildly, ludicrously off (Score 4, Informative) 229

The figure of 0.0002 pounds of pressure per photon is off by a vast degree. The Wikipedia article on Solar Sails cites a figure of 4.57x106 N/m2, or .00000457 Newtons of force ( 0.000001027 pound-feet) against a square meter of sail material given the full flux of the Sun at Earth's orbit. A single photon would provide less than a trillionth of that amount.

Comment Re:All languages suck (Score 1) 109

Java's strength in a multithreading context is due to the fact that multithreadedness was built into the language, and library authors and programmers have known to explicitly document what libraries are safe for multithreaded use and which are not.

Java the language provides just enough support (the Hoare Monitor and explicit memory model) to enable higher level thread-aware libraries, like the Java 5 concurrency classes.

Using those higher level classes can give you really good support, better than anything this side of Erlang, anyway.

I don't have to read it. A government takeover of healthcare is wrong on its face.

And one of the main reasons is that it requires laws thousands of pages long that nobody can possibly understand.

As opposed to all of the other bills that go through Congress every year? Every interest group (commercial, union, or private) has a huge number of lobbyists and legislative specialists who pore over every bill that goes through congress.

Believe me, they have read this bill.

And government isn't "taking over" healthcare. They are not privatizing the health care market, they are setting up conditions to allow a real market in individual / small business insurance to exist.

Mitt Romney did something similar with MassachusettsCare, and the Republicans proposed something similar in opposition to the Clinton plan back in 1994.

Many in the Republican party act as if any Democratic initiative is the end of the republic and must be blocked, even if they do worse themselves when in power.

By that I suppose you mean those Democrats who have supported the Republican opposition to health care takeover (which reflects the majority opinion of the American people), since there have been no overtures to bipartisanship from the Democratic leadership.

The polling on the bill has moderated a great deal in recent weeks as Obama has come out and started fighting for the bill. A number of polls now show the public fairly evenly balanced between opposing and supporting the bill.

IDEs With VIM Text Editing Capability? 193

An anonymous reader writes "I am currently looking to move from text editing with vim to a full fledged IDE with gdb integration, integrated command line, etc. Extending VIM with these capabilities is a mortal sin, so I am looking for a linux based GUI IDE. I do not want to give up the efficient text editing capabilities of VIM though. How do I have my cake and eat it too?"

The State of Ruby VMs — Ruby Renaissance 89

igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

Cancer Patient Held At Airport For Missing Fingerprints 323

A 62-year-old man visiting his relatives in the US was held for four hours by immigration officials after they could not detect his fingerprints because of a cancer drug he was taking. The man was prescribed capecitabine, a drug used to treat cancers in the head, neck, breast, and stomach. Some of the drug's side-effects include chronic inflammation of the palms or soles of the feet, which can cause the skin to peel or bleed. "This can give rise to eradication of fingerprints with time," explained Tan Eng Huat, senior consultant in the medical oncology department at Singapore's National Cancer Center. "Theoretically, if you stop the drug, it will grow back, but details are scanty. No one knows the frequency of this occurrence among patients taking this drug and nobody knows how long a person must be on this drug before the loss of fingerprints," he added.

If Firefox 4.0 isn't multi-threaded and significantly stripped down, you can pretty much kiss it goodbye. This is a terrible shame. I want to continue to support it, however the Mozilla team is shooting itself in the foot far too much.

Firefox has always been multithreaded, just like Netscape Navigator to the beginning of time.

I assume you mean multi-process, in the same way that Chrome and/or IE8 are?

What do you want to see stripped down about it? It's already very stripped down compared to what Netscape Communicator and/or Mozilla was.
