@Rojo The FE has a faulty event queue manager. So sometimes the event "Locator drag started" fails to propagate in a slow machine, and the initial action of Dynamic[] is never executed. Damn bugs
@OleksandrR. A pity ... there is a nice song about that. All things start to transform in the same character, street names, companies, car models, etc etc ...
@R.M I know a guy who has an American flag somewhere
no miracle at all
@R.M Don't engage in trying to upset me. I am too lazy to fight
Nice. I have a little pepper garden with about 5-6 different varieties... I don't have jalapeños anymore, but been thinking of growing it again next season
A friend of mine is growing these. Unfortunately I can't do so because I don't have a greenhouse, but he offered to give me some of the fruits... looking forward to trying those!
@EliLansey usually when people see dark (sometimes soft) spots on their pepper fruits, they think it's drying because of lack of water and then over compensate. Actually, the opposite is true
@EliLansey To be a little more specific, it's due to erratic watering. So they think they're underwatering and then overwater all at once, and forget about it the next few days... rinse and repeat
@EliLansey It's amazing, but you can never really keep a regular watering schedule if you're doing it by hand (unless if you're a retired old man who has nothing else to do)
That's good! For nearly a year, I put aside installing piping and drip systems and watered with a hose every few days... inevitably, your estimate of "how much" wavers and you get busy occasionally, etc...
I thought they were doing fine, but I realized how under watered (and erratically watered) they were when I finally got around to doing all the work and installing it. In the 2 months since I installed it, the plants have been flowering copiously, looking lush and greener than ever and grown more than in the whole year prior to that!
Anyway, I better get back to writing this darned paper. ugh.
The primary difference between Refine and the two *Simplify functions is that Refine only evaluates the expression according to the assumptions given. It might so happen to be the simplest form when evaluated, but it does not check to see if it is indeed the simplest possible form. You should use...
You could try playing around with TimeConstrained and TransformationFunctions, etc... not promising anything, but good to consider them.
Yeah, probably. There's no easy way to do that, I'm afraid
but although the final expression looks a bit messy, it's not all that terrible.. there's a fair bit of repeating terms and if you pull all of those out, it'll probably be a simple expression
Hey everyone, would any of you care to check the result of Integrate[Cos[a] Exp[I k Cos[a - b]], {a, 0, 2 Pi}]? Mathematica gives 2 I Pi BesselJ[1, k] but I think it's missing a factor of Cos[b] and I want to make sure I'm not crazy.
@OleksandrR. well, yes, but that wasn't the point really, since I followed it with an example. I meant that structural manipulations shouldn't be used for mathematical manipulations
I had changed all of your FullSimplify to Simplify (FullSimplify takes too long), then Experimental`OptimizeExpression[%, "OptimizationSymbol" -> var, "OptimizationLevel" -> 2]
It's basically an "aggressiveness" option--how dedicated will it be in factoring out all the common subexpressions? Possible settings are 0, 1, or 2. (But not All, unlike for Compile.)
After common subexpression elimination is done to this extent, any Fortran compiler worth its salt ought to be able to produce reasonably decent code.
BTW, setting "OptimizationLevel" -> 2 for Compile on normal procedural code seems to be dangerous as it can drastically re-order operations. But for pure mathematical expressions like this I think it is safe.
Nice, this will certainly come in handy. I do remember seeing Experimental`OptimizeExpression before though... probably mentioned by you here. Is there a question on the site?
@belisarius Makes sense; if the plant senses that the conditions are harsh, it would try to produce more of the chemicals that are supposed to prevent other living things from eating it... ;)
@J.M. That's from a darwinian POV. Intelligent design would argue that the plant, knowing its fellows are dying, commits itself to saving Tabasco's business.
@J.M. My Third personality got depressed and intended to split out. We hold a Swiss kind of government conclave and decided to send Verde to Afghanistan in order to reestablish our unity. He is now working as a drone stewardess.
