You're probably downvoted because it's been pretty widely known that Chrome is a CPU hog on OS X. Checking the energy shaming feature, Chrome is pretty much always in the "Apps Using Significant Energy" section. I did a

Well, you get a 4 week trial, so that should give you a good idea of it.

I think the developer spends more time working on PCalc, and even then, I think the iOS version gets the most attention. I last used DragThing back in the OS 9 days. With the OS X dock, it didn't seem as necessary. Couple that with Lau

I stopped using Macports for two reasons. First, it was taking a long time for some of the ports to get up to date. That doesn't seem to be a problem now, but it was. The second reason is that it insists on using its own versions of to

A fee based on viewership counts is how the anime service Crunchyroll works. A portion (the other part is Crunchyroll's) of the ad revenue and subscription fees are split based on what you watch. So, if you only watched a single show f

True. But, in my case, I didn't know if it was convex. A small change of parameters could go from a feasible solution to an infeasible solution.

Considering that if compiled into a .app it should require Gatekeeper (AppleScript does), it's not a big worry. If it's not compiled, you can easily view the source.

Well, AppleScript is well documented. See Apple's Developer Site, https://developer.apple.com/library/mac/documentation/AppleS... But, that's just AppleScript. The problem is that the scripting dict

For my Master's thesis, I couldn't get satisfactory results with a genetic algorithm, even after spending quite some time tweaking the parameters from the default. But, with the default parameters of the simulated annealing code,

I used simulated annealing for my Master's thesis. I was trying to fit a differential equation to some experimental results. With small changes in the parameters, you could get huge changes in the solution of the DE. For some of the ex

I wasn't involved in the Gamma aspects of SymPy. At this point, Gamma is probably more appropriate.

The Open Scripting Architecture (OSA) used to support additional languages instead of just AppleScript, I recall that Perl was one of them in the past. Unfortunately, this changed at point. I'm hoping that Javascript support points to

Many of the problems of AppleScript come from inconsistent scripting support from the applications. A command in one application will work subtly different in another one. Unfortunately, this problem will continue with Javascript. Back in t

I'm a SymPy developer, but I'd probably pay $15/year just to test different things so I could compare results. I won't pay $15/month, though. Especially since other developers have access to it, mainly through their

SymPy has made a start on an open source version of Alpha, SymPy Gamma, http://www.sympygamma.com The biggest missing piece it's missing is the data used by Alpha. It's missing other things as well, but it's a sta

SciPy is the closer analog to Matlab. That said, it is missing many toolboxes.

There's a couple of other things you can do. Since those are Python integers, you can specify a SymPy Integer instead with Integer(1)/7 instead. The other thing you can do is S(1)/7. Both of these should work.

SymPy doesn't appear in IPython, but IPython is aware of SymPy if it's installed so you can get nice printing of math in the notebook. Also, why link to the Wikipedia page for IPython and not the homepage? For most people, I'

As a standalone CAS, Maxima is more fully featured than SymPy. But, it's harder to use with other packages. With SymPy, you can do your work with the CAS and then use the results with NumPy, SciPy, or Theano.

I highly recommend looking at the comparison of the two mentioned in response to this. It's a bit out of date, though. It has a reference to SymPy 0.7.2 upcoming, but it's already past that. Basically, Sage is more comprehensive a

If you read the John Scalzi piece on this, it's not working with him. Everyone is talking about the price, but that's not the only thing they're negotiating. We've heard about some of Amazon's demands from some of t

Do you know which publisher sells for all your favourite authors? I certainly know for some of them, but not others. What about when you just hear about a book from someone? This is why people go to bookstores. I'd be a lot happier if

A big problem with the competing device market is that books aren't portable between Amazon and alternatives (but they are between the alternatives). So, if you've bought a number of e-books on Amazon, switching becomes much more

Swift can call Objective-C APIs, so if you're building Mac or iOS apps, you'll get access to the full Cocoa API. You can't build iOS apps in Scala (as far as I know) and I've never been a fan of Java GUIs.
