Besides the 'wood screws', the other claims about this card are incredibly suspect.
1) The connectors not showing through are hard for me to buy from just looking at fuzzy pictures as there are about 8 pixels for each of these solder points to juge from. You don't necessarily see the pins protruding way out on some parts.
2) Some of those parts with "missing" connectors could be surface mount. Like this molex power connector.
A hint: If you know exactly what you are looking for, use the website, but use the dead tree version of the catalog and you will learn a lot about the range of parts available.
I don't know what the myth part you are referring to is, I'd like to hear more about it. I used to own a small pickup truck that got around 22 miles per gallon. What I was referring to:
My car is smaller than 'most cars', although this is not a fact about hybrid technology in general.
My car has a better emissions rating than 'most cars' SULEV or something like that.
My car uses less fuel than most cars. I get around 40 miles per gallon, and I never drive on the highway. It is a bit more during the winter when I don't run the A/C.
Because it burns less fuel, my car therefore emits less carbon dioxide on a daily basis than most cars. When I stop at a stop light the engine turns off, for example.
Sure there is the energy and wastes from creating the car, but again, I think the are in proportion with the size of the vehicle, which again, is less than average. A hybrid isn't a silver bullet for environmental problems, but I still stand by the fact that it is more environmentally friendly to drive this kind of car compared to the average vehicle, or even compared to an identical vehicle without the fuel saving modification.
I own a 2003 Civic Hybrid and the new numbers presented are very close to my observed mileage after driving it for 2 years. I am a somewhat careful driver, but I'm not one of those going for extreme mileage either.
I love owning a hybrid because driving this car has less impact on the environment as a whole. Less expenditures on fuel is another plus. Having to fill up less often is convenient, too.
I feel it is just as unfair to judge the hybrid technology or any fuel saving technology as not 'economically effective' when there is a very high degree of uncertainty about future fuel prices or the behaviors of other factors. If, for example, many others drive larger and larger vehicles, then the cost of gas will increase, and it will have very little to do with my choice to buy a hybrid. Another thing that could happen is that manufacturers switch to diesel. Will diesel still be economical 10 years down the road if consumption of diesel fuel increases significantly? Today spewing carbon dioxide into the air is free. What if we begin paying for carbon offset credits at the pump?
In summary, using less fuel and emitting less pollutants makes sense for our driving culture. It is a shame we can't convince ourselves it makes sense at an individual level.
I've been using Yahoo! mail for about 3 years as a paid subscriber.
The #1 complaints I've seen about Yahoo! is the ads. Aren't there ads on gmail as well? Furthermore don't you feel creepy when you realize its been reading your mail to determine what to display? There are no ads when you pay and you get the nifty disposable email addresses.
They have spam filtering and it works pretty well. It looks like only about 1 in 100 get through for me, and they are those new pesky stock plugging ones.
As far as the interface goes, the Beta email is pretty darn good. I use Thunderbird at the office and the Beta client feels very similar
- A continuous scrolling list of messages - no paging
- Drag and drop messages to folders
- Displays some atachments inline
- Links to check my other POP accounts
- Indicators of which messages have been replied to
- Multiple tabs to view and compose messages at the same time.
My wife uses Gmail and its interface appears to be pretty limited compared to the Yahoo! beta I've been using for a while, but I am not a gmail user myself.
Those pellets,by the way are sea salt mixed with ammonia. The hydrogen is stored in the ammonia and the ammonia is converted into N2 and H2 when needed.
I am not an expert, but I recently read that the making of ammonia (which we need a lot of for the purpose of creating inorganic fertilizer for agriculture) is a pretty energy hungry process. It is estimated that about 1% of the total world energy output is consumed by the Haber-Bosch Process. So, in its current form, these pellets would be kind of impractical as you need ammonia to put the hydrogen in.
That being said, its a renewable process and not dependent on a precious metal. All you need is a huge energy source to start the process, or some improvement in the efficiency of making ammonia, as is envisioned by some sort of biotech or artificial photosynthesis process.
It is hard to believe that all these folks saying "learn without an IDE" have done both. I remember learning to program in many different languages during college. For these, I used the 'emacs' and 'vi' method (the teachers didn't even teach us to use 'make'). Learning the syntax of a new language is tough, and someitmes the 'raw' compiler messages aren't very helpful. Of course, this was supposed to be a difficult course, so it was important to make things as difficult as possible. But I got pretty good at it over about 15 years as a professional programmer.
But, if you are not intending to teach a flunk-out make it really difficult course and are more interested in teaching a course about programming concepts, by all means, USE THE IDE! With an IDE like eclipse or Visual Studio, you get informed of silly stupid syntactical mistakes right away, hight lighted in red with a suggestion about what to do to fix it. If they never get to program again in that language, at least they have had some sucess using the concepts and didn't end up with a tangled up mess because they struggled all night just to get the damn thing to compile!
I only used an IDE on a regular basis starting about 3 years ago when learning Java. I was productive in the language almost right away, even though in many ways, I didn't know what the hell I was doing. For an object oriented language with lots of classes, it is a huge handicap NOT to use an IDE. You can think about what you are trying to get done, not about reading through tons and tons of code you didn't right trying to figure out how to use it.
We used Reiser 3 for a long time on our systems in with the 2.4 series kernels. It may not have been the "first" journaling filesystem for linux, but at the time we installed, it was the first production ready version. We were very thankful for it reducing the time to reboot and fsck on our (at the time) very large filesystems.
Over the past several years, we had pretty good luck with using Reiser on root and data filesystems. Good luck in the sense that we never encountered something we couldn't recover from. However, we did have more than one instance of filesystem corruption that would crash the kernel (We used it on several of our development servers). The warnings on the 'rebuild tree' utility weren't very reassuring, but it always seemed to work. We also had instances of corrupt files by sticking random bits of data of other files at the end.
I'm migrating our servers slowly over to ext3 as we upgrade them, mainly because it is more mainstream and I prefer my source code sunny side up as opposed to scrambled. I noticed that the same number of files seems to take up less room (10% or so?) on the disk overall with Reiser than with Ext3 (as reported by df).
The $200,000 figure is too good to be true, unless
these are retired icebreakers (that's what this reactor was designed for.) If they are retired icebreakers, then yeah, these may cost $200,000, but you won't be able to build new ones for that.
Yeah, I'm not sure how they really got it
to work either, but you can put more power
through a 7805 if you include a beefy enough
heat sink, which allegedly they did. However,
120Watts? That sounds like a bit much. My guess
is that he didn't REALLY get 120 watts through,
but enough current to warm up the chips
nicely. As you know, it only takes
one CPU to fry an egg.
I was thinking the same thing. Would you have
to build a 60MW microwave station on Mars to slow
it down? Will someone have to put a new coat of
paint on?
If you are thinking about using this for a manned
space flight, the return trip wouldn't be as speedy. If it is a solar sail then the last I checked, the solar wind only blew in one direction.
Dr Huang is pretty famous, and famously evasive
about following up on patients that have gone
through his procedures. MIT's Technology
Review has a subscribers-only article about Dr Huang. Basically, the criticism is that he is providing a theraputic procedure that has not really been studied, and he refuses to study the long term results. Although his techniques may have benefits, this is not regarded as the best that stem cell research has to offer.
I don't think NASA is holding anyone back from
volunteering to go up and fix Hubble. If there
were some huge benefit to doing that, I think
you might hear some volunteers out there.
NASA calculated that that servicing mission,whether
robotic or shuttle, would cost over one billion
dollars US. The only "market" that could pick up
that kind of tab (or anything close to it) would be the Japanese or European space agencies. Private companies have a hard time just
getting a sattelite into orbit. The Russians might have the technology, but they
could not realistically fund the mission.
According to This source, the total annual budget for the ESA is 2.7 billion Euros. The Japanese budget according to This source was around 1.3 billion US Dollars in 1998. So we are talking about asking them to take on a project that would cost them between 30% to 80% of their total annual space budget.
The probability of success of a robotics mission is IMHO extremely low. You would be hard pressed
to build a robot that could service hubble if
it was sitting on the ground, much less orbiting in zero G in the cold of space.
Assuming the Japanese and Europeans decided they wanted to pool resources and take on this relatively huge project, then farm it out to the Russians for the launch platform and manned
mission (because they are the only ones that
have that technology), what would be the end result? Another 5 years or so of science.
(remember, we have a new telescope that will be
online 5 years or so after Hubble goes dark.)
The rewards just don't seem to be worth the
effort.
I love the science as much as anyone, but for
the most part, the great view of the universe from
space isn't going away. It will still be there
in 5 years, or 10 years, or however long it takes
us to get the next great telescope into space.
I read an interview in some kind of industry
trade rag that Torvalds works from his home.
He was named #1 IT person of the year or
something like that and they came out to his
home and gave him an interview. One of the reasons
he joined ODSL was so he could spend more time
with his family.
I tried it on a couple of boxes. It tries to
exploit a race condition, so it won't necessarily
work all the time. However I have tried
it a few dozen times and haven't gotten it
to work yet. (One RH 7.3 box and one RH 9.0 box)
My sentiments exactly. Maybe this is not the permanent answer, but we've spent a lot on
Yucca mountain, and the waste should be safe there for hundreds of years, if not thousands. If something better comes along, it should be no
harder to move it from Yucca than from anywhere else. On top of that, it will be in a secure, centralized sparesely populated location.
An interesting idea, but I think this equation is a bit too simplistic.
First of all, in a Delta II there's no place to sit!
Second, even if it were unmanned (just use Soyuz to get the people up there) there is no infrastructure to steer your cargo toward ISS and safely rendevous. I think that infrastructure will take a big bite out of the Delta II payload.
So we'd have to spend the R&D on a new third stage with rendevous capabilities, and the total payload would be reduced.
You get datagrams like in UDP but they are sent re liably.... or not depending on what you want. I
believe this has been quietly implemented in
CISCO routers and Unix OS vendors network stacks
over the past few years.
I don't know about the "pot smoking hippies" part,
but I tend to agree that this is not a major
contribution to science or technology. I'm not so sure that Canadians should be proud that $600,000 of what was probably taxpayer's money were spent on this project.
Having said that, someone down below posted taht "Solar powered transportation is not practical." Well, these guys did it. I think the fact that they have ridden it hundreds of km around the city shows it can be done. They are not engineering prodigies, but they have shown that you can do it AND in the end you can do it fairly cheaply.
PSSST Electric cars can be practical.Some think there is a conspiracy to killelectric powered vehicles like the GM EV-1 (I would have sent you a link to GM's official information on the car, but I can't find it!).
There is such a thing as a geek girl. In our last house, my wife is the one that ran all of the cat5 in the house. In fact, in true geek fashion, she insisted on it - I guess she thought I would mess it up like I did the 120V electrical wiring (sheesh- anyone can make a mistake!)
She has more computers than I do,
more gadgets than I do. She gets the palm upgrade first!
Here here! I am irked at my 31% score. Some of
my answers were "right" in that I guessed close to the answer (same order of magnitude), but I was highly uncertain. I was penalized for that and
got zero points for several answers that I would have judged "good guesses." I think I went
astray by putting too much "uncertainty" on some of my answers.
Here are samples of the scoring I got:
population of the whole world in 2004
Yours 6±1 billion
True answer 6.38±0.005 billion...
got 8 points.
number of floors in the Empire State Building in New York City
Yours 100±20
True answer 102 exactly...
got 8 points for that too.
number of words in Jane Austen's novel Pride and Prejudice
Yours 100000±200000 words
True answer 122093 words exactly...
0 points
My guess is w/in 20% of the real answer, 0 points.
distance from Edinburgh to Cardiff, as the crow flies
Yours 500±500 miles
True answer 310±5 miles...
My guess is about 40 % from real answer, within my bounds of uncertainty, but 0 points nevertheless.
Fraction of the adult population of the UK who are functionally illiterate
Yours 20±10 per cent
True answer 20±0.5 per cent...
5 points
My guess is almost right on the money, closer than the population of the world guess, but I put too much uncertainty in, only 5 points.
Had I been a computer, I think I would have put in put in guesses better for judging. I think Edinburoug is in Scotland (somewhere). But I am a yank and hampered by my lack of knowledge of the kingdom. I have no idea where Cardiff is (now that I think about it, I guess it is in Wales). It is probably on the British Isles, so it is no more than 1000 miles away. I've driven from London to Manchester and it was around 300 miles. So my thought was " my guess is it's about 500 miles, but its somewhere beteen 200 and 1000 miles for cardiff to whales. So I put 500 +/- 500 miles. The "right" input for my guess to get a better score probably should have been 600 +/- 400.
