Death by Coffee?

· Score: 3, Informative
This seems straightforward:
Too much caffeine can lead to caffeine intoxication. The symptoms of this disorder are restlessness, nervousness, excitement, insomnia, flushed face, diuresis, and gastrointestial complaints. They can occur in some people after as little as 250 mg/d. More than 1 g/d may result in muscle twitching, rambling flow of thought and speech, cardiac arrhythmia, and psychomotor agitation. Caffeine intoxication can lead to symptoms similar to panic disorder and generalized anxiety disorder. The LD50 is estimated to be about 192 mg/kg of body mass, or about 72 cups of coffee for an average adult.
So it would appear at 100 cups, you would stand a good chance of checking out.
Caffeine From Wikipedia
Though RangerRick has done a lion share of the work (vastly more than probably the rest of us combined) there are a lot of other people involved in the project as well who have contributed a lot of time (Martin, IceFox,,ChArles etc..) albeit with less to show for it (with the exception of IceFox) I personally blame X11's virtual keyboard.....*damn you X11 virtual keyboard implementation*
But yes, things are coming along quite nicely in the KDE-Darwin land =)
In addition to Halo (which is awesome) check out Apple Games. It contains the largest (as I know it) layout for mac gaming both commercial and shareware on the web.
Uggh. Taxonomy. Your statement is true to a point. It all depends on how far you want to go down. It is true that Pumas and Panthers are of the same genus and species (Felis concolor of family Felidae and subfamily Felinae) Now the trick.....
There are approx 30 known sub-species worldwide, 13 in N. America
F. concolor azteca Merriam
F. concolor browni Merriam (Yuma puma)
F. concolor californica May
F. concolor coryi Bangs (Florida panther)
F. concolor couguar Kerr (eastern cougar)
F. concolor hippolestes Merriam
F. concolor kaibabensis Nelson and Goldman
F. concolor missoulensis Goldman
F. concolor olympus Merriam
F. concolor oregonensis (Rafinesque)
F. concolor shorgeri Jackson (Wisconsin puma)
F. concolor stanleyana Goldman (Texas panther)
F. concolor vancouverensis Nelson and Goldman
So they are the same only to an extent.

OK, now that is as base bones as it gets.
Currently priced at: $1691.76
Again no wireless ethernet, no bluetooth, no USB (unless it is integrated), no Firewire (again unless it is integrated), no keyboard, no mouse, no OS, very basic sound and video.
Not as inexpensive as one would be lead to believe.

Wow, being a BioChemist I am thrilled hearing this kind of talk.... Understanding is tough to pin down. There is understanding: I can fix my car when it breaks (for the most part) and there is *understanding*: I can build and design a new type of engine. I think some of the talk about being able to recognize the general trends that occur in chemistry is the best approach. Knowing how electrons move, for example in an SN1 or SN2 reaction, does not necessarily require one to understand the quantum mechanics behind that reaction. Well, to a degree. To *understand* the reaction, in that my-PhD-is-in-theoretical-organic-chemistry kind of way, you would need to know it, but to the lay person, it is almost extraneous information. This is because all sciences are interdependent. If you dive too deeply into one subject, you invariably learn alot about the rest of them. I like the Biology -> Chemistry -> Physics example. You look at proteins, how they function, their form, which is dictated by the amino acids which behave according to their charge or hydrophobicity/philicity which in turn gets into electrostatics and repulsive forces etc... further and further down the line....you could go bonkers. If you intend on pushing the limits of knowledge, new theories, new mechanism etc.... Then yes it would be necessary to have that sub-atomic/QM framework to work under. If that is not your goal, then:
1. realistically know the rules (not the exceptions, that can come later) 2. realistically know how it works in a larger framework of the system (structure=function=regulation for example) 3. and to a degree, why it works that way
And like someone else mentioned, chemistry is very large, polymers, analytical, inorganic, organic, biochem. I mean, there is a branch of chemistry that deals solely with the reactions and behavior of Flourine (pretty wild stuff too, well for chemists)
You could spend a lifetime doing that...but enjoy yourself, I think it is a blast.
Wrong, not heat based. As someone pointed out correctly later in this thread, the button senses the capacitance of your finger similar to how a trackpad senses your touch.

I have had a good deal of luck with mod_mp3.
What made the comment out of line was his remark that any code that did not come from the FreeBSD side of the road was of poor quality.

This goes without saying but......"You can't ignore backward compatibility."
This coming from the VP of a company that makes a 64 bit processor that has zero 32-bit backward compatibility?

oh yeah! It was "Hey guys we have finally achieved cold fusion.
Like previously stated, I will believe it when I see it in the journals.
