Sure there are a lot of vehicles, but the complexity can be managed by the following easy two-step process: 1. Today switch passenger cars to the right hand side 2. A week from now follow with the trucks too...
Switching to SI must be done it will cost, but will save in the long run: 1. Start using both units in all labeling/measuring devices. Need Federal law for this, since some backwards states would never do this out of "pride". 2. Use both units in everyday life (e.g. my car can display speed in both km/h and mi/h) This includes, speed signs, recipes etc. 3. Switch elementary school text book (math, physics) examples/exercises to SI. 4. Switch in high school/higher education and in science.
I was born in Europe but live in the US. So I know it will be hard for the folks here. I still have to recalculate body and oven temperatures. It will take a generation to switch.
The old units will live for a long time. They are present in literature and will be in the archives. We watched on PBS a Dickens adaptation and had no clue about the money they refered to: guinea. We wanted to get a "feel" for how much money they talk about in certain situations. We read up on it on Wikipedia, the history is interesting.
Handbrake probably works for most people. I also tried x264enc which I prefer over Handbrake.
But presently I do not use either: I use mencoder directly. I write scripts based on mencoder forum comments and ones that x264enc generated.
I got better results (quality and control) with x264enc. This was end of 2008. Since then I am using my scripts only. I posted one to the mencoder list (search on gmane) which I used to encode over the air HD broadcasts. I extract the closed captions as well and reencode the audio (6 channels if availabale) into ogg. (See oggenc, ccextractor.)
Regarding DVD-s the only issue is the closed caption extraction. I use OSS OCR software (tccat, tcextract, subtitle2pgm) and the quality is far from perfect. I lot of spell checking (ispell) and editing is needed.
For new warm-up stretching technique I recommend a search on warm-up for skiiers. The goal was to have a routine that works in a cold environment, does not require you to lie down (take of skiis) etc. It is based on PNF (proprioceptive neuromuscular facilitation) stretches when you push against something but no actual movement takes place. One idea is to not "grind" your cold joints with movement at the start, and second take advantage of the efficiency of PNF.
I do competitive ballroom dancing. (2 minutes of Viennese Waltz followed by 2 minutes of Quickstep will already get your heart rate up.) I use the above mentioned PNF concepts too, because in dance studios or on competitions there are often no room to lay on the floor and stretch. (You may had to stand around in a tuxedo waiting for your turn so you want to do some unobtrusive stretches before you finally enter the floor.) On warm-up I follow the PNF stretches (which indeed get the blood flowing) with static stretches to "verify" my range of motion. This helps with knowing where my body parts are (appears to be a major issue with people who cannot dance).
> Godel of course proved that you can never have a complete list of all true statements in mathematics.
Bzzzt. Wrong.
What Godel proved was that all mathematical thruths cannot be described by a finite axiom system. The statement that there is a single empty set cannot be proved. Similarly continuum = aleph_1 cannot be proved; in both cases one may argue that these are so "obvious" that they need to be accepted as axioms.
Note that continuum = aleph_1 was a strongly accepted conjecture as much as the Riemann hyp today.
I studied set theory and models. It is fascinating that you can have a countable model of set theory! This model is basically built from a countable set with countable many subsets accepted as sets, etc. The rest of the subsets an "outsider" can see are not known inside the model. We denote this model (which is a counatble set for the ousider aka meta theory) by M. The natural numbers are in M, denote it by A. A is known in the model and A is an infinite (countable) set.
The set containing the subsets of A, denoted by P(A) is different depending on whether you look inside or outside the model! Outside it is an uncountable set, of course. In the model world it is Pm(A) and it appears uncountable again, but for the outside observer it is actually the intersection of P(A) and M. Bear with me another minute!
In the model world of M the Pm(A) appears not countable. What does that mean? It means that there is no 1-1 mapping between A and Pm(A). In the outside there is a mapping of course, since both sets are countably infinite. This mapping (a function) is actually a set (everything is a set: function, relation etc.) so a mapping denoted by F between A and Pm(A) exists outside. However F is not an an element in M so it does not exist inside the model.
There is a way to extend the model M into something called M(F) by 'forcing' F to be in M. Basically we add F and everything else that need to be added to still have a valid theory inside M. It is not trivial to do this, it was discovered and proved by P. Cohen an analysis guy (not a set theorist). Set theorists of course run with this ever since. The careful picking of F allows different M(F)-s to be created and that leads to results showing that continuum = aleph_1 is not the only possibility. One can 'force' a bunch of other alephs under the continuum. (What aleph exactly can continuum be is also interesting to set theorists at least.)
Now there is one model called L which consists of the 'constructible' sets and nothing else. In L continuum=aleph_1. There are in fact theorems based on the assumption that V = L, that is V the world consists of only constructible sets.
You may wonder how this L can be defined. I cannot go into the details, but one eye-opening fact though is that you can define Lm inside the above M model!!! This Lm is a countable model of L and in some sense a minimal model of set theory if I recall correctly.
So one may take the position that we want mathematical thruths in L the minimal system. (This resonates with Occam's razor.) Of course note that there is no axiomatic system describing L.
I want to emphasize that if we fix a model then each statement has a truth value; but there exist truths which cannot be proved working inside the model only.
For the usual applied math we could say we assume V=L. (Or any other well defined model for that matter.) Note againg that aleph_1 == continuum in L, because there are no other alephs that could fit "between". The mathematicians inside L see this as this: we cannot prove that aleph_1 == continuum in fact there could be something between, but it is not constructible from what we have.
> Sort of like if a woman isn't married by 30, she's over the hill.
The existence of such a limit is not irrational. It relates to child bearing potential etc. However, consider the status of an unmarried 35 year old woman and an already divorced 35 year old woman. The society appears to view the former a loser while the latter not so much, if at all (religion may factor in in some locations). The difference objectively is that one had a failed relationship for sure.
> Now that her number has been associated with the scammers
Somewhat off-topic, but if someones identity is stolen do they have to change it as weel? New fingerprint, SSN, name change...?
Anyway, in her place I would:
1. Report the death threats to the FBI. I know that the shmuck making the threat had no clue that there is such a thing as caller ID spoofing (neither did I), BUT making a death threat was wrong and further even other threats (say legal action against a scam caller) should be preceded by making sure you got the right guy. If she reports all those making the threats, then suddenly more people will wisen up that there is a problem with the system (caller ID spoofing is possible) and will work for the needed change.
2. Consider legal action against the phone company. The company sells the caller ID service for money, I would check the fine print whether some liability may fall on the phone company because the incorrectness of the info. At least the phone company should educate its customers that the caller ID info is not guaranteed to be acurate.
Hmm. We may see some advantage emerging from internet telephony: ssh based authentication would take care of this.
Now why phone companies do not have authentication methods developed I do not know. Maybe because they have not done anything novel for a while? And note that wireless companies are not much better. New fancy phones are rolled out, but the single feature I am looking for is not a camera, music player, but the capability to *screen* my calls so that I could say that from 9pm till 9am only a list of numbers (family + close friends) could ring my phone. Callers with blocked id-s should never be able to ring my phone, etc.
> That's why I'd wish we'd tax the Hell out of the most non-green businesses.
It should not be (called a) tax actually: it should not depend on being profitable or not. When said company pollutes, dumps etc. then it should pay for the cleanup. The only shift we need is to realize that clean water, clean air, clean soil etc. is not free.
In Europe they have a "product fee", supposed to cover the safe disposal/reuse etc. of the product at the end of its life. A step in the right direction. I would calculate how much does it cost to extract the various harmful/undesired (Pb, CO2,...) by-products of burning gasoline and add that cost to the price. That would suddenly make cleaner burning fuel cells look much better. One may even consider reducing this fee for low emmission gasoline using vehicles in some form.

> She wanted a trooper fired for tasering his child?...
Not that I condone his actions - highly unprofessional - but the way you said it may give the idea to some readers that he used the taser to subdue the child.
"In his interview with troopers, the stepson said it hurt for about a second, according to Wall's report. The boy said he wanted to be tased to show his cousin, Palin's daughter Bristol, that he wasn't a mama's boy. The probe left a welt on his arm, he said. His mother was upstairs yelling at them not to do it, the boy said."
We hear there is a financial crisis going on that needs immediate action. The senators still found time to deal with an issue of limited importance in the short term. My conclusion is that either:
A. The action regarding the financial crisis is not that pressing as they present it. B. The senate has issues setting and following priorities.
I ruled out C. PRO-IP is immediately needed and cannot wait (even until next year).
I read the Gallup analysis. They failed to discuss whether this study implies that being a Republican causes the underreport of their mental health problems or instead unreported (untreated) mental problems lead to "Republicanism". That was my first question after reading the stats.
Others pointed out that the GPS works on private property too, while following needs a warrant.
But that is not the point I am trying to make. What are the costs of this GPS tracking?
1. Special GPS device with:
a. accelerometer (so it works for a while without satellite signal)
b. encryption for signal so results are tamperproof (so accepted in court)
c. removal detection (so accepted in court)
Say $75 considering it is not mass produced on a scale of the ipod...
2. A specially trained police agent who can install this device so that the collected data will hold up in court. 1 hour job: $100 (gross, not salary)
3. Traditional surveillance so that they know when and which vehicle to tag. 8 man hours (very optimistic): $500
4. Monitor the device. Assuming excellent IT and administration automation tools: 1 man hour a day. Assume 8 days before busting the guy: $500
5. Put in a call to judge for warrant, prepare paperwork: 1 man hour: $75.
6. Judge looks at it: 1 man hour, but not billed to police actually.
Total $1250. It seems they are trying to cut down on the $75 item 4 representing about 8% of the cost. I do not think it is worth it. Especially considering the extra cost of defending the practice in court.
Make sure you set the jumper enabling SATA II. The default setting limits throughput (presumably to enable it to work with older motherbords). My 250G Seagate (in a streaming HTPC) gets 94MB/sec after the jumper reset, before it was 55-65 like my old Maxtor. I also just got a 1TB Seagate too for the media server, I will post results of that as well.
