Comment Re:Another silly decision (Score 1) 480

Homes are a subsidized tax break for the top 10 percent of our society, paid for by the renter class and those who pay taxes (usually the bottom 95 percent).

They do limit your moving options, since your cost out is higher than cost in for the first 2-3 years, or 10 years if you buy high and sell low (approx 7 year cycle) like most people do.

That said, for most people aren't in the bottom 10 percent, they make sense. Until they seize the house on a made up pretext.

Comment Whatever or why raffles win and lotteries wont (Score 1) 480

Sigh.

Look, if you do win, you'll burn through it very fast and end up no better, and with fewer friends and upset relatives than if you didn't bother at all.

That's what happens.

Raffles on the other hand, since they return 100-400 percent of the expected value, tend to do a lot better.

(caveat - I have won raffles, lotteries, and many forms of gambling myself, but that has nothing to do with your odds)

Comment Re:Nuclear fission has higher carbon than measured (Score 1) 309

You're thinking of the single stage versions that go from the surface to earth orbit. Multi-stage (platform) is currently possible, and viable for lunar at the moment, and we're almost at the point where we could do a Mars version. Depends on how you lift and the speed and wind profiles. Switch to a balloon method - hydrogen gets you high enough that the air resistance drops so that you can go higher.

You confuse "difficult" "non-elegant" engineering problems with "impossible" problems. It's not impossible. Just not elegant or simple.

The first part of the lift cycle uses the most energy, after all.

Comment Re:This would be fun to hack (Score 1) 36

Depends on the feed protocols. Would be far easier to change the text and color displays, and have the headset send back an "override: incorrect identification" message back to the system. This "clears" the subject long enough for them to proceed and confuses, due to high levels of mismatch. Any system without such overrides would be non-functional, due to real world constraints.

Basic application of social engineering - find the most common override that shuts or delays the security and use that. Don't upgrade from BAD GUY to VIP, upgrade from BAD GUY to NORMAL or from NORMAL to VIP. Play the numbers.

(caveat: none of this will impact real world risks, which are already set up for failure)

Submission + - What Will It Take to End Mass Surveillance? (alternet.org)

Nicola Hahn writes: Both the White House and the U.S. Intelligence Community have recently announced reforms to surveillance programs sanctioned under Section 215 of the Patriot Act and Section 702 of the Foreign Intelligence Surveillance Act. But do these reforms represent significant restructuring or are they just bureaucratic gestures intended to create the perception that officials are responding to public pressure?

The Executive’s own Privacy and Civil Liberties Oversight Board has written up an assessment of reform measures implemented by the government. For those who want a quick summary the Board published a fact sheet which includes a table listing recommendations made by the board almost a year ago and corresponding reforms. The fact sheet reveals that the Board’s mandate to “end the NSA’s bulk telephone records program” has not been implemented.

In other words, the physical infrastructure of the NSA’s global panopticon is still in place. In fact, it’s growing larger. So despite all of the press statements and associated media buzz very little has changed. There are people who view this as an unsettling indication of where society is headed. Ed Snowden claimed that he wanted to “trigger” a debate, but is that really enough? What will it take to tear down Big Brother?

Submission + - Arkansas Declares a High School CS Education State of Emergency

theodp writes: Aiming to deliver on Governor Asa Hutchinson's inspired-by-Code.org-and-others Plan For Job Creation Through Technology Education, the Arkansas House voted 99-0 last week to require high schools to offer [but not require] a course in computer science, either in a traditional or online setting, starting this fall. Hutchinson learned last December that the state has only 6 qualified instructors to teach CS to high school students, so it's envisioned that the courses will be offered online through Virtual Arkansas ("where AR kids are Our kids"). Interestingly, House Bill 1183 includes a pretty dire-sounding Emergency Clause: "It is found and determined by the General Assembly of the State of Arkansas that computer science and technology skills are of vital importance to meet the growing needs of the workforce; that public school students need opportunities to develop computer science and technology skills in order to be competitive in the future; and that this act is immediately necessary to ensure that the Department of Education has the time necessary to develop and modify academic standards for computer science courses before beginning of the 2015-2016 school year. Therefore, an emergency is declared to exist, and this act being immediately necessary for the preservation of the public peace, health, and safety shall become effective on: (1) The date of its approval by the Governor."

I'm a bit concerned about the fusion source materials. Would have to cost them out cradle to grave as well, including their processing before and after. Since it's still in test phase, am not going to weigh in on a process that's only partially complete.

The problem is the "they" you refer to. Different "they" groups exist. Isolated spaceships or military bases with difficult logisitics for fuel supply might find the cost/benefit ratios different. Places dependent on coal with no ready supply of wind or solar PV or solar passive might have different values.

The problem is that any real measurement of global warming impact has to be done using the Cradle-to-Grave methodology to be true. The mining process is fairly bad in impacts, and the 10,000 year storage and movement and cleanup dilemma makes it a non-starter.

Now, don't get me wrong, I've owned nuclear fission utilities in the past. But it's highly subsidized and not a good choice at all.

On the upside, nuclear fusion research is promising here at the UW, so if your heart is set on nuclear, maybe fusion will pencil out.
