Hi everyone, I don't expect to find a solution here because this thing I'm looking for is particularly picky, but I will try.
OK, I'm doing a lot of number crunching that involves complex numbers. I need a calculator that is a software either on Windows OR the ipad that can handle complex numbers easily, without much fuss. I'll explain:
There are three ways of writing complex numbers that are common:
a+bi (rectangular form)
A<B (where A is the magnitude, the "<" is actually the symbol meaning "angle", and B is the angle in DEGREES)
e^iTHETA (THETA is the character that I don't know how to write here)
OK, the e thing (the last one) is lame. I hate using it, i think it's the least useful one for calculations. The other two I use all the time. Ideally, I'd like to use both of those forms all the time, even mixing up both of them in the same formula. So, I'd like to be able to multiply two complex numbers together with the two numbers expressed in either form. Most calculators can't do this. They normally require you to input it in the first way. So if you already have it the second way, you have to first convert it to the first way if you want to use the software. Mathematica does this, and it's really annoying. I can write a function, but I don't know how and I don't want to learn it right now. I just want buttons, and one step conversions and solutions.
So, just to clarify, I'm looking for a nice GUI calculator solution, not a programming solution. I don't want to do it in Matlab. I don't want to write a script. I don't want hewlett-packard cult RPN stuff.-superboyac (December 15, 2010, 06:08 PM)
; pretty normal for a sketch ! I however maintain my remark on the page being too wide.Lightcrafts' $50 Aurora can partly be called a simple version of the$200$100 LightZone. As such, it is really good at this new time limited discount price: $25. However, I don't know if the rebate code somehow is connected to me ("Exclusive offer for PostworkShop customers") or if it is usable for you as well: (CPN5366133890)
I have to admit that I don't trust Aurora or LightZone to ever be updated, but of course I don't *know*.-Curt (November 29, 2010, 08:11 AM)

Yup - I can confirm that this is true (I've done it!). My issue is having to have iTuness installed at all. Of course, they could very well have tamed the beast, but when I ran it before it installed several services that I could not get rid of, including an Outlook add-in. Hence my irrational loathing of it.-Darwin (November 18, 2010, 10:53 PM)
Dropbox sync for some useful files, password management sync'd through dropbox, etc.I don't suppose you could use Dropbox to do the majority of media syncing for the Touch, could you?
The podcast management in iTunes is reasonably well done, and also simplifies the way I use them.-MerleOne (November 17, 2010, 11:11 AM)-TheQwerty (November 17, 2010, 11:15 AM)
Not sure I did, but I will ! Thanks. In the mean time, if someone here recognizes the synopsis...
Have you checked the list at his website, maybe one of the titles will jog your memory - there are excerpts from the ones still in print. Maybe his earlier SciFi stuff, (all out of print)?

He has/does write under a few pseudonyms - almost all the books I've read under his name, (and Leigh Nichols), have been Suspense/Thriller with a touch of SciFi, (barring childrens and non-fiction).-4wd (October 20, 2010, 05:07 PM)
Just finished "Life Expectancy" by Dean Koontz. Have started reading "Dragon Tears" by same.Hmm Dragon Tears is for me one of the best from DK !-kyrathaba (October 17, 2010, 02:39 PM)

@MerleOne - with regards to backing up into an archive file - I am very reluctant to add this. Another person asked for a similar feature over an email, let me just copy-paste my reply here:
...
With regards to the "can't set ownership on dest files" issue - I saw this before, and it was triggered by a file being initially copied from another machine or created by another user. So bvckup ended up making a copy of the file not owned by the user whose account it was running under. The first copy would succeed, and the second copy will fail, because the destination machine will (quite reasonably) refuse bvckup full access to the file owner by another user.
I was wrecking my head on how to properly handle this setup, and I think the most sensible thing to do is to detect files that are NOT owned by current user and make Bvckup ask the user if it should copy the ownership information...
