Wow,

I'm getting more amazed every day by this platform. At the beginning I was quite sceptical about the moderation of the community (many people have been banned due to feature trolling), but they really seem to have taken off. I heard the production of the raspberry pi has passed the two million mark.

I will certainly try to install mathematica!

Kind regards,

Eelco

Note that it is only free for non-commercial use, which looks rather like vendor lock-in to me.

Nick

You beat me to it!

Was trying to install it this morning, but my SD card is too small.

Setting up a virtual Raspberry Pi now in emulation...

Regardless... THIS IS HUGE. Expect Mathematica 10 on a tablet very soon. It's bring your own device time!

Only in the year 2013 can we hear:

"Ho hum... the most advanced computational platform in the known universe is free if I push a few buttons from my chair... oh, but wait, it's vendor lock-in. No thanks Mr. Wolfram"

To the 99% of the world's population that cannot afford this... it's a gift. :)

I speak as one who works with colleagues trained to carry out statistics as students in the ubiquitous SPSS package who now face bills of 12 thousand euros per licence in the work environment under IBM's new licensing scheme.

Wolfram Alpha is just the tip of the iceberg. Mathematica is a huge environment. It's been under constant development for 25 years.

Ouch ! I don't know anything about SPSS... but I assume that type of software is supposed to pay for itself with results? Looks like a one-year "Grad Pack" license only costs students $99.

Looks like a good software deal. What does the hardware + required peripherals + 600MB+ SD card cost?

The Pi is $35. You'll need a monitor capable of HDMI input, a usb keyboard and mouse, and a 4Gb SD card (and an Ethernet cable). And a way to power the Pi via micro-usb 5V.

I don't know if Wolfram has locked it down to Raspberry Pi only... but there are certainly much faster arm platforms available...

I have full instructions on how to do all of this for free, via QEmu emulation in Ubuntu 13.10; but emulation is very, very slow. Just send an email.

Bonus: Turn you raspberry pi into a touchscreen mobile device... like the DukePAD and run Mathematica:

https://wiki.openjdk.java.net/display/OpenJFX/DukePad

Not yet cost-effective... but give it two years and something equivalent will be for sale in the gas station checkout line for 20 bucks.

This time next year you'll probably see Mathematica 10 for sale in the Google Apps Store.

Depends a little on what you already have. But Pi + SD-Card + USB-cable will be about $50. I can connect to my Pi using *ssh* and run *wolfram* and get:

pi@raspberrypi ~ $ wolfram

This is rather fast. Or then I can start

*mathematica* which will pop up a screen.

That's a little slow but you can draw graphs and stuff.

But I must admit I'm not that familiar with both.

Press "==" aka two equal signs and you can enter Wolfram Alpah queries...

there is a free solution, which does ALL what SPSS can and infinite more (i.e. much prettier figures !)...

R

therefore NOBODY has to pay a cent for statistics software...

I use R extensively myself, but the issue here is the hidden cost in time and expense of retraining a team who are heavy users of an existing package (the vendor lock in I spoke of) which suddenly goes through the roof in licensing costs.

I have noticed more and more university departments switching to STATA which offers a powerful alternative to SPSS and includes a graphical user interface to lower the entry barrier. At least the full licences are reasonably priced.

It will be interesting to see the impact this has on hand held calculators.

Mathematica pretty much does everything any calculator does and in most cases does it far better. It is definitely more feature rich than any calculator.

If I were developing a new calculator from scratch, I'd seriously consider using Mathematica for the internals and wrapping a device specific interface over the top. This would mean a more capable CPU and some extra memory but both of these are cheap these days.

The Wolfram Language would likely be the implementation language of choice too.

I can say, absolutely 100% without any reservation, that if Mathematica were available on a hand-held device (of my choice), I'd **never** buy another calculator again. I'd eBay my entire collection immediately before prices fell. Modern calcs are like abacuses in comparison... even the Prime, TI nSpire, etc.

Mathematica on your own device is coming; it's inevitable.

A computing platform where your work is synced on the cloud, you can collaborate with anyone in real-time, voice input, "keyboards" that not only morph and predict your needs but never break, the world's data at your disposal...

A child born today will never press a "physical" button again.

Watch it! Then Google (et al.) also knows what you're calculating, and what you did calculate before and ... :-(

Seems I'd prefer standalone calculators still.

And you've hit a bit of a problem right away. Is the answer to *What's the derivative of sin x times cos x ?* **cos(x cos(x)) (cos(x)-x sin(x))** or **cos(2 x)**? Natural language is horrible as an input method for mathematics.

Last week I got to play with a Dell Venue 8 Pro. Quad core atom, 7.5+ hours battery life. Runs real windows 8.1 so full windows x64 compat. My friend had installed visual studio and was doing a build on it. Amazing and fits in my large coat pocket. First windows 8 device that I want.

I was eligible for a deal and was able to order one for $200. Install mathematica and your dream is reality.

You may be right. Most people - even most forumers - use their calculators mainly for real life calculations, however. And if such a cloudy device is going to replace calculators ...

The HP 28S derived calculator application for the iPhone called ND1 does this for its symbolic calculations by calling Wolfram Alpha:

"Solving, calculus: not directly supported; for differentiation, integrals, taylor series, solving, variable isolation, the app goes out to WolframAlpha.com and displays results in integrated web-browser."

That's nice to know. But slow compared to using a browser directly.

Thanks

So that the employer can be sure everyone is (mis)using their own software licences?

I paid $77.95 + tax for this bundle at amazon. It comes with WiFi and HDMI cable, plus some breadboarding gear including a GPIO breakout adapter.

Vendor lock in? Absolutely. I'm doing this as a hobbyist so pfffft.

*You can see - if you look closely - that Scotty is missing part of the right middle finger.*

This wouldn't have stopped him from typing that fast, but the lack of typing skills when they had become unnecessary in the future would. That's a weak point in the scene.

James Doohan really missed part of his right middle finger, according to Wikipedia:
