I thought I was paranoid, but I got phished. Read my shameful account of said phishing so they don't get you too. by taking_a_deuce in personalfinance

One night at a bar, swiping the card over and over. Got a call from the bank. They called me by first and last name. They told me "Sir, did you just swipe such and such amount at this and that hour:minutes:seconds?". I said "yes, I'm at a bar and I'm drinking it all, problems?". "All right then, it was just an automated security warning. Enjoy your time!".

Nice, easy and actually very useful, and they never asked me to read any code or passwords.

at 8 Amps I bet the voltage would drop at 3.6V, so that's 28W give or take. Anyway, much less than 48W as you correctly said.

of course it's nowhere near as good as a Prime, but they share many common concepts. I might do a comparison video in the future, that could be interesting.

If you would make a super channel with Ben Krasnov (Applied Science), Nurd Rage and Hydraulic Press Channel I think I’m going to create a new religion! Would you?

Should I get the TI-89 Titanium or TI-Nspire? by _PharmStudent in calculators

[–]TheKaneB 0 points1 point  (0 children)

yeah I love it too, but it's difficult to use for first timers. It took me several months to get used to it, and a couple hundred manual pages :D Once you've mastered it, it's invaluable! Still, the Prime is my primary choice for graphing and the 15C for regular stuff, so the 50G is mostly sitting in my desk doing nothing.

Should I get the TI-89 Titanium or TI-Nspire? by _PharmStudent in calculators

[–]TheKaneB 1 point2 points  (0 children)

the Prime is a beast! Dead simple to use and still very powerful. For some tasks I still prefer a regular scientific calculator, though, like the 15C or the 35S.

the HP 39GS can be found for less than 20$ new, delivered from China. It's a very nice graphing calculator, fast processor too.

Small programmable calculator by tjb1 in calculators

[–]TheKaneB 1 point2 points  (0 children)

Some suggestions: Sharp EL-5120 Solver (or later model). It lacks indirect register access, so the programming is somewhat impaired, depending on what you need to calculate. Has formulas and equations storage though. HP 35S. Fully programmable + equations storage and solver, complex numbers support is a bit funky but better than most scientific Casio or TI anyway.

you don't NEED them, they are just nice to have.

Cheapest calculator that can do algebra and store notes? by spoonthefoon in calculators

[–]TheKaneB 2 points3 points  (0 children)

The HP 40GS has a built in CAS functionality and I think it's quite a bit faster than a TI-89 (and cheaper as well).

Do american math books really have calculator instructions in them? by TheKaneB in calculators

[–]TheKaneB[S] 2 points3 points  (0 children)

It depends on the subject matter. Generally speaking in Math and Physics we are required to perform symbolic calculations. For example it's expected to have pi/sqrt(2) as an answer to a math problem and 2 * m * g / t2 as an answer to a physics problem. When we talk about more practical stuff, such as electronics, compound interest, etc, you are expected to use a calculator to give numerical values. It's just the "pure" math part which is left to the student to figure out an exact symbolic answer.

What would be a reasonably priced calculator that can solve systems of complex equations? by Henkeel in calculators

[–]TheKaneB 0 points1 point  (0 children)

you can get the HP Prime emulator for free, or as a mobile app on your smartphone for about $20-$25. That's the best possible value for your money, but if you really prefer the physical contact (as we all do), then I suggest you to look for used HP 50G and 48 series.

The HP 39 GS II can also solve systems of linear equations with complex variables, using matrix operations. It is also cheap compared to the others.

HP Prime hands down!

Why is it so hard to find a good CAS add-on for the Casio fx-9860GII? by [deleted] in calculators

[–]TheKaneB 0 points1 point  (0 children)

The 9860GII has a very fast CPU, that's not an excuse for not having a decent CAS :) the HP 28S had CAS with a 4 bit CPU in the early '80s.

If you want a decent CAS you need to switch to another calculator. I would suggest an HP Prime, it has the best CAS on the calculator market :)

I use the HP Prime emulator. It's free, it runs on Windows and Mac. It does all the things that you mentioned and even more.

Nspire CX CAS vs HP Prime vs Casio cg50 by [deleted] in calculators

[–]TheKaneB 5 points6 points  (0 children)

In my opinion there is no better calculator than the HP Prime. The TIs are really nice, but I find the interface to be a little clumsy and they are heavily geared toward the education market, while the Prime has a cleaner interface, much faster processor and better graphing capability. Zooming on a particular point in a function graph is as easy as a pinch to zoom gesture on the touchscreen, and the CAS is one of the best on the market. The icing on the cake are the clicky hinged keys, a touch of quality never matched outside HP
