There must be something wrong with the power management. I just moved from an Air -- which runs cool and gives 8h battery to the Escape-13in pro. It gets very very hot, uncomfortable even on the plastic keys. 4h battery. It's like going back 10 years in power use.
Mail runs with an energy impact of about 60 most of the time [gmail+pro imap]. Same useage pattern as my older Air. Lets hope there is an update on the way.
There is a lot of political pressure in Paris to push out diesel motors, which are often the main source of summer pollution peaks. This one actually has another origin: (French source) http://www.airparif.asso.fr/ac... .
There is actually a cloud over much of north Europe, not just Paris. The origin is firstly agricultural. Its mostly ammonium nitrate from spring fertilizer spreading. The second source is wood burning out in the country. Diesel is the third source in this outbreak.
The real political problem is the impossibility of doing anything against big-agro, not diesel. (Similar problems in France also occur with water pollution -- impossible to regulate)
There is the problem of web sites too- one popular site generates mountains of of javascript garbage every times you scroll. See for instance the bug 656347 in the mozilla database.
The site? Slashdot. Mozilla is not happy the way Firefox manages this, but relying on garbage collection very time you push arrow down is bad.

Firefox 4 Beta 8 Up
·
· Score: 5, Informative
It has been a turd since this summer, mostly due to the bug in the SQL code which killed interactive performance. It was repaired this week and should make beta9. It is also in recent 3.6 builds so mainline firefox is almost unbearable.
Meaningless javascript benchmarks are not very useful for this sort of bug- which gives 10 second hangs when working with history or bookmarks.
Reading the various explanations on mozilla sites- this will (one day) give a just in time compiler and virtual machine for javascript in firefox. This should lead to big speedups in many web applications
A major technical problem of integrating field equations is in the propagation of/constraints/ on the components. Ie GR describes the time evolution of a tensor for which all the components are not independent- for instance they obey Bianchi identities. http://mathworld.wolfram.com/BianchiIdentities.htm l
Simple numerical integrators destroy these identities at order dt^n for some small but finite n. Run the code forwards and one can find finite time blow ups due to the stepping algorithm- however even after a single time step the numerical solution has unphysical aspects
Big science is a favorite villain of many or even most scientists. Much of the best science is done in small groups of less than 10 people in universities. Science as done in the biggest organisations (NASA anyone) is often wasteful, uninteresting and dead end.
Just browse some of Rob Parks' articles at http://www.aps.org/WN/
Groups in optics, quantum mechanics, materials science or biology are usually SMALL. The are, evidently, part of a large community of other people looking at the same problem.
Big groups and integrated NSF centres are a plague drowning investigators in administration and bean counting.
Well do I think that the people
publishing in journals do it for free?
Well yes we do, or we even pay
the journal a page charge in the case
of many academic science journals.
When I send out an academic paper I typeset
it MYSELF. I also give FREE opinions to
journals as to the quality of other submitted papers. I have colleagues who do the editoral
work for FREE as well. In chemistry the
publishers make large amounts of money
off the academic community. It is different
in physics where many (not all)
journals are published at near cost.
There are thus variations of several orders
of magnitude in cost/page in scientific publishing.
Where does my salary come from? From my university.
Certainly not from published works.
Mathematica (Wolfram Research) is one of the two best symbolic mathematical programs around (I use both it and Maple), and its interface is specific to the operating system on which it resides. So when I had to change OS (market forces, not preference) I asked WRI if it was possible to rewrite my Mathematica license (same computer, same user, different OS), so I could stay legal and above board. Sure, they said, sign an application for change, pay a fee, and all will be well. OK, I said.
But I read the fine print on the form I needed to sign. It authorized WRI to search my home any time they wanted to, and required me to cooperate in their search, so they could assure themselves that I didn't still have a hidden copy of the previously licensed program. I pointed out that even the Director of the FBI needs a court order to search my home, and that requires convincing a court that there is a reasonable presumption that something incriminating will be found. So, after a certain fuss, they waived that requirement in my case. But when asked if they were planning to remove this appalling clause from their standard form, I got only "my supervisor is aware of the problem." A dime says it is still there.
Read the fine print.
Adobe's way of looking after the customer

Copyrant

· Score: 3
I have bought exactly one piece of software from Adobe. Some years back I decided to get Illustrator for Unix. After all postscript is nice, this seemed to be an honest firm, good products.
I went away and installed the software (this is in France). When I launched the software I found that it needed licensing keys. Oh dear yet more time lost. However all the contact information in the box (Email and UK telephone numbers) was out of date. No way to get a reply. I spent hours phoning though to the US to try and track down the European licensing center. I took me 10 DAYS to license the software.
Three months later I received a letter from the Adobe law office saying: We see that you have Adobe software in an Educational institute. We reserve the right to come and search your machine at any moment for potential violations of the license. Your acceptance of your software license implies our right to examine all machines and backup media in your possession.
They can't even answer the phone to give out a license number, but they have time to send the bailiffs in to personally read everything on my machine...
