Too bad there is no option in my preferences page to block myself from logging in? I have tried putting 127.0.0.1 in my etc/hosts but I eventually realized slashdot will resolve anything, asdf.slashdot.org still works!
For distillation, you don't use "two or three passes". You use a distillation column with a few (20-40) trays. Ethanol comes out the top, water out the bottom (usually).
It takes energy, but usually you can do heat integration to save a lot of energy in a chemical plant. If you have a stream that need to get hotter and another that needs to cool down, you put them through a heat exchanger to save on utilities.
EtOH has another problem, it forms an azeotrope. You can't easily get above 95% EtOH using simple methods. You can put in an organic and break the azeotrope, but then you need to distill twice. I doubt your engine can run with 5-10% water...
Butanol is an interesting one, it settles out from water without distillation. Or rot anything and collect methane. Or algae based biofuels. If oil stays above $100/barrel, a lot of these become interesting. Problem is, most companies are worried it won't stay up. Back in the 80s, oil ran up to $40 / barrel then dropped to $10. That would be like dropping from $120 to $30, which I doubt will happen...
The latest I hear was coal for gassification. Methanol can apparently be made at about $0.40 / gallon. But volumetric energy content is lower, so it is really like $0.80/gallon. And they can sequester a lot of the CO2 in the process. Lots of interesting options...
The global cooling issue was a 1 time tabloid issue. It was never in the science world other than 1 article. Only idiots point to that. My middle school science text in the early 80s presented both global cooling igloo effect and global warming. I guess they were covering their bets...
I really don't think global cooling was a 1 time tabloid issue. Looking at the always reliable wikipedia, looks like more than a single 1970s article... http://en.wikipedia.org/wiki/Global_cooling
So I am a skeptic. Stick with some theory for more than a couple of decades and I will buy in.
And you can make your own songs too. When I gave a step pad to my wife for Xmas, I downloaded a bunch of songs but also made a few step songs for her using songs she and I both liked. The interface for custom songs is very easy to get into and produce something usable, assuming the song has a constant beat you can sync up to.
We never got into it enough to upgrade the pads, and we never got the laptop to work with the home TV system. Recently we got the DDR game for the Wii and our pads still work through the gamecube ports (most pads have multiple connectors). We can have three people dancing using the Wii DDR game (and our sweet 52" TV)
Privacy is something we expect from our government. Google Orkut and other online services are not our government, they are private entities. They aren't even common carrier (at this point).
Think of another bad slashdot analogy: Coffee shop. You are the proprietor and you overhear a bunch of pervs meeting every Tuesday to share pervy info about kids. You should probably call the cops, not just wait for a warrant or the police to ask you what you know. Call the cops with a tip and maybe some supporting evidence, let the cops get a warrant to collect legally binding evidence, supply the evidence as requested, then send them all to jail.
I assume Google could put something like that in the EULA for their services. "Private" to google should mean we don't publish it online to the public, not that they can't ever look at it. I think that fits under "do no evil" as in users should do no evil too.
If you want to make a private perv net with a private perv-friendly EULA, go ahead. It is like moving your perv coffee house meetings to a private location with sufficient privacy for your needs. Cops would have to do traditional procedures for wiretapping suspects which I think are better established without a third party involved.
I think there are a few simple puzzle games for multi-player in flash. Maybe a couple of action games, but I have not tried them. Wiicade.com has a bunch of everything.
I really just meant the Wii is fun and simple and you can do web stuff with it easily...
I don't think the way we learn has changed, just the technology now makes it possible to do more visual and spatial instruction.
When all you have is a chalkboard, all you can do is a chalk talk. Now that tools are there for rapid content creation, things should change slowly.
The US was lauded years back for great hands-on engineering labs. Now that you can do virtual labs, maybe this will take a hit? As someone who has taught with both, I can tell you anecdotally that hands-on real-world wins by far...
And I thought spatial reasoning was valued as a higher level of thought? Or is that different from learning spatially?
Sadly engineering and science profs are rarely given formal instruction on educational methods. One thing that I did pick up in my limited instruction was that people learn visually and sequentially, so you need to cater to both (read+equation AND graphs+figures). Usually the visual learners get left out, so now they have a better chance in some cases...
Humans make mistakes. Maybe the first human overlooked something on your ticket, so the second hopefully will catch it...
Think of it scientifically. If the humans are 99% effective at catching whatever they catch when looking at your boarding pass, one layer would miss 1 out of 100 evildoers. Two layers makes that number 1 in 10,000. Of course, the effectiveness of one layer is still debatable...
I would like to see personal interviews more commonplace, like how they do with the Israeli airlines. Just a few questions for each person, hoping to pick up cues. "where are you going?" "what are you doing there?" kind of questions. Of course, that could be seen as stereotyping people...
The tech school can offer a few things you may not get at the liberal arts school.
Technical connections - you meet people that will go out and work in the industry and should be in your network one day. Of course, the liberal arts people may grow up to own the business one day (or may grow up to use that English degree at the local Starbucks).
Weeding out - Technical schools are pretty good at seeing if you sink or swim. A department with 12 graduates has a vested interest in getting them all through the program while maintaining academic standards. A department with 300 graduates can cull the bottom third and still be doing fairly well numbers wise.
You can succeed from both directions, but your probability of being successful long-term is probably better at a tech school.
I considered a double major in engineering and music performance. Instead, I went all into engineering but kept doing music for fun. I still do music for fun. You can find "liberal" stuff to do at tech schools, be it music, theater, literature, etc. Travel abroad, work at the paper or literary magazine, take classes from a nearby "liberal" school, whatever. The suffering and pain you get at a technical school is justified (I hope).
Ouch. Astroturfing insult! Usually I am the one bitching about turfing on slashdot.
I wish I had MS giving me money to pimp vista. But Vista is not that great. It just is not as bad as I expected. And my recent linux experience has been worse. I have been running Linux on and off for a decade and I have been a proponent of it all that time.
I switched back to XP a couple of years ago when I got a new box with a giant 30" LCD and Linux did not have NVIDIA support for the requisite dual DVI card. It was painful. Any my machines only got owned twice (thanks cygwin for opening xwin!).
The only reason I went to Vista, I heard it worked better on tablets.
As for staying with XP, I have support at my university for windows. When a box gets owned, I just ask my guy to fix it. When I have to set up and maintain a linux box, it was on my own on my own time.
Software wise, cygwin gives me most of what I need. I can't get konsole to work right, but in general I get all the nice unix stuff with windows software. Yes, I have made Maple and Matlab work on linux in the past, but it was sometimes problematic. With XP is usually just works.
Yes Vista takes forever to load.
Yes Vista nags you on occasion.
Yes Vista reboots more than XP for me.
I have not hit any DRM issues yet, but I have not tried to do anything interesting either.
I just got a Vista laptop (tablet!) and it has not been terrible.
The nag screens are only on occasion, and it makes feel better knowing that something is checking to see that exes should be running. The annoying thing is that you can't "personally sign" an application, so that the next time you run it it does not bitch at you.
The thing I like, Vista application switching is a lot smoother than my XP experience. I have not run into a lot of lag when nothing happens. Of course, I run 50/50 on hibernate (lots of reboots after hibernate). But it has not been as awful as I expected.
And my wubi knoppix install won't even boot to a usable environment. Worked once, now I get a black screen. Nice! I don't have time to troubleshoot this crap!
Exactly. Was there a Brinn vinette where the old man recorded a conversation with some kids and it got popular on the internet? This was a neat idea of shared video way back before youtube...
I want to record my boring life in 1080p... That is about 10GB / HR, about 1 TB/week assuming you don't record yourself sleeping. 50 TB / year, a few Petabytes over a lifetime. 1 TB is now $200, so it could be done for $10k/year now.
I think Moore's law was originally about cost, that the number of components per cost doubles every year or two.
So really, this drop tp having cheap 32 bit procs is really Moore's law.
And it really looks like we are hitting a wall in top end speed. 1 GHz was top back at the turn of the century. Now we are still doing only around 3 GHz. Of course, they are now 64 bit and multi core, but I am not sure the effective serial speed has increased at the traditional Moores law pace, although the economic version or Moore's law holds.
Slashdot Mirror
In my day, we had talk, finger, vi, and elm and we never complained! Green vt100 terminals were all anyone really needed! Get off of my lawn!
Seriously, talk had advantages over IM. You actually could see what the other person typed as they typed it, including backspaces...
And finger worked great. I knew a nerd that had his
The more things change, the more they stay the same.
I spent a Cinqo de Mayo in West Lafayette a few years back... We hit the Taco bell after a few rounds of margaritas. Good times (for Indiana)

Richard Felder offers classes on educational methods, I have seen him a few times. He does something similar to a MB personality test, four dimensions of classification. http://serc.carleton.edu/NAGTWorkshops/earlycareer/teaching/learningstyles.html
One of the dimensions is visual-verbal. Lectures generally include a lot of verbal content (droning on) but many times have limited visual component.
Active-Reflective considers hands-on vs. sit back and analyze the situation and act later.
And there are two more dimensions. Ideally you do things in class that help all the students...

Beg borrow or steal one of the 2650x1600 30" LCDs. I doubt your current laptop will support dual DVI, but my LCD monster is a godsend.
:=)
I never got into the multiple monitor habit (or monitor + laptop) since I never want to turn my head or look across a gap.
This giant monitor is big enough to have three pages side-by-side at 100% or two at ~%125 .
Development, email, browsing, excel, ppt, pdfs, whatever. Finally I have a computer desktop that is the size of a desktop and I am happy
Plus you can watch 1080P video without any sort of image manipulation required since it is 1920x1080.

You don't get halfway intellectual talk on digg?
What game is this? How do I play? Mod down astroturfers? Or just get points for calling them out?
XP drives me nuts, so when they fixed some of the things in Vista I was happy (or at least not angry).
Switching applications should be instantaneous. Not on my dual Xeon box running XP.
Clicking on the start menu should open your program list. Again, not on my XP box. Why is that not cached?
Add/remove programs- why must they wait 5 minutes to parse the system. Why is that not done offline and cached?
