@JM heh, it's the effect of first day of private beta. Upvotes are easy to find like sand in the Sahara. Fastworward 3 months and it'll be like finding water there
Private beta questions can sustain you during lull days... I still live off my private beta rep on Signal Processing... I had 1.5k when private beta ended and now have 2.3k... I think I've maybe added 5-8 answers since then. Still get the trickle upvote
@acl I mean the "Wizard" part of his name. He's a wizard, which can mean "expert" in some contexts. It also works with the fact that many of his posts seem to work magically.
@acl: You have access to machines with 512 GB of RAM? I wish..
I thought it was more expensive. not so excessive then (of course there's many of these here, with lots of processors--but they're used by many people for a long time, so overall it probably isn't that much). and I don't think that many run mathematica on them :)
@acl Well, the RAM can be cheap. I'd imagine the sort of machines you're working on probably have a much higher markup on top of that. IIRC you have a bunch of mini super computers on site where you work.
I recently narrowed down on some specs for my work desktop (which I'm trying to get approved). So if I build it myself, I can get a 24GB RAM w/ 256 SSD and 2TB 7200rpm drive, core i7 (and other small stuff) for about 600-700ish
That is simply shocking!
That's way too much computing power for one desktop at such low a price
drool I don't even have an SSD on this machine, or even 24 GB of RAM. I really don't know how computer manufacturers make profit with how cheap parts are now.
@MikeB actually I am working on a 11" macbook air, and just run stuff on the big machines :) (mind you the i7 in the laptop is faster per core than the cluster machine cores)
In mathematics, computational science, or management science, mathematical optimization (alternatively, optimization or mathematical programming) refers to the selection of a best element from some set of available alternatives.
In the simplest case, an optimization problem consists of maximizing or minimizing a real function by systematically choosing input values from within an allowed set and computing the value of the function. The generalization of optimization theory and techniques to other formulations comprises a large area of applied mathematics. More generally, optimization inc...
Also, if anyone has access to edit privileges can they please review my edit for this question? I removed the superscripts from the question because Mathematica doesn't play nice with them.
@MikeBantegui constrained-optimization isn't that wide an umbrella. Again, if you're dealing with the use of FindMinimum[]/FindMaximum[], that'd be unconstrained optimization.
@JM Fair enough. I still think there should be a separate category for these types of problems. optimization might work on SO since most people would equate it with program optimization, but on here there's a very wide range of things that could reference.
@MikeBantegui We need diamond users here I think. None of us has those privileges yet. Maybe you guys who are mods at other sites can ping an SE employee at your private lounge?
Well having someone who can at least review edits would be nice. Otherwise we can't really improve the quality of posts until someone gets a high enough rep.
@acl: I emailed you about those papers you mentioned last year w.r.t free fermion <-> hardcore boson transformation. Just wanted to give you a heads up.
@J.M.: I just saw your profile. How did you create the avatar in Mathematica?
Hm.. They overlap very heavily, when I posted that I thought Notation was the best term. You do bring up a good point since it is a package and not the built in behavior.
On a side note, I love the Mathematica community. People here are so much nicer in general than on SO. I remember having a few bad experiences with high rep users who dismissed because they thought I was asking for something because I was a "bad programmer."
I've had similar experiences; one of which, I managed to solve without having any concept of what I did. (A build stopped working, and then started up again.)
@Verbeia that wasn't supposed to be the discussion side of things. Grrr ... One of the proposal ones. This one.
@MikeBantegui Yeah, that would be perfectly fine. I was just about to say we should have performance-optimization as a synonym because some people are going to type "optimization" into the tag box, and something relevant should come up for them.
@MikeBantegui I'm almost tempted to get rid of program-optimization in favor of performance-tuning, as I think it addresses the question more specifically.
@rcollyer "How do I extend X to implement Y?" Of course - there will be plenty of particular cases, so everyone can have a go. I've already asked two questions so far, so I can pace myself.
How do you guys feel about placing questions about packages under packagename-package? They're usually distinct enough from the core libraries that it could be useful.
@Verbeia It's funny, I thought about what I wanted to ask (extending graph-theory) and decided I didn't care quite enough to write a question about it after I asked you. Need to think it through a bit.
@MikeBantegui and it's used in at least one other question, thus far. So, it was a good suggestion. I think my question is a little bit light weight, but it's a start. nine more to go.
@rcollyer Likewise, but out of the three I think Mathematica is the most fun to work in. It can also be horrifying, but usually C++ does "better" in this respect.
Don't know how to deal with that other than walk away for several minutes and see if the UI eventually responds enough for you to kill Dynamic Updating.
@rcollyer That's precisely the reason why. I thought because it's so early (barely two days old) that it might be discouraging. Especially because I didn't recognize the poster.
@rcollyer You didn't know about subvalues before David's answer? I ask because you mentioned it in the question and made me look (only to not find it there). ??SubValues works though
So I have something of a predicament. I can have either asynchronous evaluation on random kernels, or blocking evaluation on a specified parallel kernel.
@David I think you'd see that there was an Edit pending (edit link becomes Edit(0)), and there may have been a method near the top once you enter the edit page.
@yoda I don't mind gardening. I just couldn't resist.
@rcollyer Actually, I realized after being SO room owner that it's pretty useless. You can change settings, add feeds and change to gallery, etc., but you can't kick anyone, freeze the room or invite low rep users like we tried to with SMiranda
Would it be too much of a meta question asking for impressive and short Mathematica programs? I've met quite a lot of people asking me "you and your Mathematica, what's so great about it, I can just use Origin for plotting and the Windows calculator for the math".
@rcollyer no, actually it does come with powers, but the question is whether you'll be able to use it as much. I mean, we won't get the same amount of traffic as SO, hence fewer problems.
I've only had to destroy 1 user on gardening, message 2 and merge 1 on dsp in all this time. SO mods do twice that every hour
well, you need to be a mod on SO. The best combination is 10k on both SO and MSO. Then you get to see crap on SO get downvoted and shut down and then the same chap goes to MSO to whine about it where it is met with further scorn.
