Gold on the internet regarding the Riemann Hypothesis and more some of the most interesting and understandable results you'll find

Finally a decent explanation of the Riemann Hypothesis you won't find this stuff in laymans books on the subject at all I've done a lot of research on it & it's great to finally find stuff of this quality on the net.

Proof of the_Euler product formula for the Riemann zeta function

Correction of a proof on the internet which got millions of hits which is bullshit 1+2+3+4.....=-1/12 the guy Mathologer who made this video is masterful, and, well worth following on YouTube.

Hi Denis,
While this might not be directly related to your proposal, you might find the following formula tree visualisation interesting: The displayed trees correspond to the semantically richer structure that my speech rule engine uses internally and that we use in MathJax to voice formulas.
Best, Volker

Also, you might consider the \texttip and \mathtip macros in "action" extension for TeX input (if you are using TeX):
or the <maction actiontype="tooltip"> element if you are using MathML input.  These will display a tooltip when you hover over an element, so that might b…

Atomic Scramjet Drones for Mars

As I covered in my book, The Nerds Survival Guide out of print, Richard Feynmans idea of Atomic Jet or Scramjets which zip around orbiting in the thin upper Atmosphere, till they reach well beyond escape velocity, &, can spiral slingshot faster and faster in the thinner & thinner atmosphere trying not to melt from friction,  to the Moon, Mars, & beyond, rather than using Rockets is a fantastic idea as no propellant is needed saving loads of weight. It might even still be able to accelerate in free Space if there is minute amount of Gas in the Vacuum of Space.

My three enhancements are based on how technology has evolved are to use Drones ( already done ) ,we can't put Humans on them for the moment  as the amount of Lead needed for the human Habitat to prevent radiation killing the Astronaut & Miners is damn heavy for a flying vehicle,  an extended TCP/IP commodity Mobile Phone Network reaching to Mars to make communication cheaper using Stun & Turn & ICE se…

Raspberry PI it's much cheaper and better than One Laptop Per Child ideal for computing in the developing world

At $26.99 from Amazon here, &, even less from he Raspberry PI Zero W is quite a machine, you can't go far wrong.
This plugs into the hdmi socket of a TV.
Here is the Raspberry PI Zero W running a DOS game I wrote, Boozy the Alcoholic Horse in 1993 almost perfectly. The game is available for free download here. It also does Microsoft Word compatible word processing and web browsing.
It is a little sluggish playing YouTube videos as it only has 512MB RAM but with
RaspiCast a free Android App you can stream full screen YouTube videos from your phone to the TV through the Raspberry PI the phone doing most of the video processing.
It has Wifi so you can tether multiple raspberry pis to one phone to access the internet ideal for
teaching in third world countries.
The mini keyboard in the video cost under $3 in bulk from here.

If you say it's not portable, it can be powered from a cheap USB Battery used to recharge mobile phones purchasable from Dealz a b…

Getting legacy pre internet programs accessing the internet without recompiling or modifying source code, Cobol, Basic, DOS etc.

This is a hack, also known as rerouting legacy file system calls to an internet server. If you don't have the source code available for a program but need it to access the network where it otherwise would access files, this can be done provided you know the file formats of the data your program your interested in and simultaneous access to these files from multiple sources isn't neccessary.

A typical DOS program which might make use of this technology would be to let a legacy point of sales till update a webshop stock & maybe even able to handle new products uploaded to the webshop. The till would need to the DOS program restarted at set idle times like teatimes, lunch break & overnight to sync with the web server as regularly as possible. File access is exclusive to one program at the time, no concurrency.

In DOS you'd do it this way in DOSBox,
Modify the DOS/BIOS/kernel( e.g. Linux) or the emulator code ( e.g. DOSBox ), the emulator code would be easier to access…
