Soda Pop Damages Your Cells' Telomeres

penguinoid Re:Overly broad? (320 comments)

OK Mr Anonymous Unverifiable PhD, what if you do a different study? In this new study, thousands of studies are done, and show results with p-values p-1, p-2, p-3, .... However, the results of most of these studies mysteriously vanish, lets say a bunch of them aren't reported by the researcher, and a bunch more are not accepted by any journal of note, and vanish into obscurity. The vanishing studies aren't random, but the vast majority of them are ones where the null hypothesis were not rejected. Besides this, the journals select for the most "interesting" studies, which for this example let's say it means that the results were surprising and in contradiction with either conventional wisdom or previous studies. Let's call the remaining p-values tainted-p-1, tainted-p-2, tainted-p-3. These p-values are nothing new, but rather a subset of the original set. Let's say only 8% (the acceptance rate of Nature) of the original studies make it to this second group, biased towards the more "interesting" studies with mostly positive results.

So my question to you is, are you equally as confident in the hypotheses from the smaller subset of studies as you are in the hypotheses from the second set? And what, if any, is your mathematical reasoning behind this answer?

penguinoid Re:Overly broad? (320 comments)

The p-value does not measure the confidence people have that the hypothesis is true. The p-value is the probability that the given results support the hypothesis merely as a result of random chance. This means that every sane person considers the probability of the hypothesis being false as higher than the p-value, sometimes several times higher, depending on circumstances.

For example, if someone tested 20 hypotheses with the same dataset, and only reported one with a p-value of 4%, it is almost certain that the results are meaningless, as per the linked comic. When you factor in the bias toward reporting interesting experiments with statistically significant support for the result, both on behalf of the researcher and the publishing journal, some would consider it generous to have even 20% confidence in an "interesting" result with 4% p-value.

A p-value of 5% is the absolute minimum allowed in most scientific professions, although several require an even smaller p-value. The only reason p-values that large are even allowed, is because of the economics (and sometimes ethics) of performing experiments. Eg it is more worthwhile to do 10 studies with sample size 100, and then 1 study with sample size 1000 to verify the most interesting result, than to do a single study with sample size 2000.

No More Lee-Enfield: Canada's Rangers To Get a Tech Upgrade

penguinoid Re: a quick search (253 comments)

I should like to hear your proposal for gun parts made in anything other than 3 dimensions.

Also note he said a 3D scanner, not a 3D printer, although I'm fairly certain that merely knowing the shape is not sufficient since how it got that shape lends a lot to its mechanical properties.

Florida Supreme Court: Police Can't Grab Cell Tower Data Without a Warrant

penguinoid Re:Yeah yeah (109 comments)

Ignorance of the law has never been an excuse, in tradition dating back thousands of years. Though nowadays everyone including the judge and lawyers are ignorant of the law an it is not humanly possible to know all the law. Anyhow, who ever heard of a thief getting off because he claims he didn't know *stealing jewelry while wearing a tuxedo* was illegal (the law never mentions jewelry specifically nor tuxedos, does it?), and promised from now on he won't do exactly that? That's about as believable as those cops claiming that stealing *people's private communications using Stingray towers* was not illegal, and then being told OK but don't do it again. I mean, they might have some sort of case if it weren't for the towers impersonating real ones.

Florida Supreme Court: Police Can't Grab Cell Tower Data Without a Warrant

penguinoid Re:Yeah yeah (109 comments)

Geez, and I was so hoping they'd be recycled as homeless shelters.

That was one of the uses for prisons while they were still open, though they were more exclusive (ie, required applicants to commit some sort of crime to be allowed in).

That reminds me, there was a recent article about a prisoner shortage. As a bonus, putting these criminals in jail will also most likely stop all this complaining about a prisoner shortage.

White House Wants Ideas For "Bootstrapping a Solar System Civilization"

penguinoid Re:Baby steps (348 comments)

How do you know their strategy isn't "Convince the US to give up research so they won't be 'losers'. Then we can finally get ahead of them."? After all, why else declassify that strategy given its not complete?

White House Wants Ideas For "Bootstrapping a Solar System Civilization"

penguinoid Re:One word: (348 comments)

Aren't you supposed to earn awards before you receive them?

When the Nobel Peace Prize Committee consulted with their time-traveling division, they were told: OK, this guy is going to start a bunch of wars, which will be embarrassing at first. But he'll also finally put us on a path toward space colonization, which will forever change the face of war -- not only will it change the "us vs them" dynamic, but it will also make offensive wars prohibitively costly compared to defensive. Yup, give him the prize.

10 evolutionary commandments

penguinoid penguinoid writes  |  more than 8 years ago

So, what are the 10 commandments as evolution would have them?
1) I am the gene your God, who brought you out of the land of non-existance
2) Thou shalt have no other gods besides me.
3) Thou shalt not swear falsely in my name. (root word for testify is testicle)
4) Remember that your genes run in many things, to keep them alive.
5) Honour thy father and thy mother (for they share half your genes) that thy days may be long upon the land which the gene thy God giveth thee.
6) Thou shalt not use birth control
7) Thou shalt not commit adultery, unless you can get away with it.
8) Thou shalt not steal, unless you can get away with it.
9) Thou shalt not not bear false witness, unless you are bribed or it is advantageous to do so
10) Thou shalt not covet thy neighbours stuff. See rules 7 and 8.

Anyone care to improve on this?

Funny/Overrated murders karma

penguinoid penguinoid writes  |  more than 10 years ago

So I posted a joke to a story about estimating. Now it wasn't a particularly good joke, but evidentially quite a few people thought it was very funny, others didn't. Results:

* +11, Funny
* + 1, Insightful
* - 9, Overrated

* Karma:Exellent --> Karma:Good
* "Your IP has been temporarily blacklisted due to bad posting"

Now I have heard that +1, Funny and -1, Overrated will change karma by different amounts (specifically, funny will only add a little while overrated will take off a lot). If that is so, I really think that it should be changed in the following manner: Overrated should take off just as many points as the current positive attribute the post has. If the post is at or below the karma level it was posted at, remove a different amount of karma

The scientific view of religion

penguinoid penguinoid writes  |  more than 10 years ago

It seems my sig,
The scientific view of religion is not atheism. The scientific view is agnosticism and simplicity.
seems to have generated quite a bit of commentary. So I will explain, and feel free to post your views.

I regard atheism as the religious, totally unfounded belief that the set of all gods is { } (the empty set). This is not to be confused with agnosticism with leanings toward atheism, which starts with no preconceptions but tends to believe in atheism because of some rational reason. This might be based on science (especially Occam's Razor), or on the belief that several million scientists are probably right (which is not such a bad argument).

Likewise, I regard the term agnosticism to mean simply "no preconceptions as to the set of gods" and thus not a religion. I wouldn't require an agnostic to justify his views, because there aren't any to justify. (As opposed to the stronger version of agnosticism, who believe that the question of whether there is a god or not can never be answered, who could be asked to justify that belief.)

And yes, I pulled these definitions out of my ass.
And yes, I would have written my sig clearer if it did not have a 120 char limit.

And finally, I will mention that I am annoyed by people who think atheism does not count as religion and is therefore an acceptable point of view for schools/government without any further justification. Don't say atheism is not a religion. Call it a religion, or if you prefer, anti-religion. It is not neutral. It has its set of gods.

As for my own views, I am a confused person who grew up with a Bible in one hand, and an encyclopedia in the other. I see the Bible as a valuable guide on how to be a good person and as a history book (not necessarily completely accurate, but you can verify lots of the important events). Likewise, I try to figure out how the world works through the scientific method. However, I find the moral advice given by the theory of evolution to be disturbing.

Broken surge protector

penguinoid penguinoid writes  |  more than 10 years ago

I left my computer rurring during a thunderstorm recently, and I think that my surge protector got blasted. Now, the surge protector shuts off randomly (about once a day). Is it normal for broken surge protectors to do that? Is it bad for the computer/OS to be shut off like that frequently (I have EXT3 and Debian 2.4.18)? Or should I just get off my arse and buy myself a new surge protector? Thanks!
