Mmm, time for some pie!
m4r35n357··on Implementing the Exponential Function
Just a suggestion, have you looked at the MPFR project, and derivatives: https://www.mpfr.org/

http://mpfr.loria.fr/mpfr-current/mpfr.html#index-mpfr_005fs...

It is way to deep in the grubby details for my pay grade, but who knows?

m4r35n357··on Implementing the Exponential Function
[Aside on Taylor Series] The section on recurrence relations is the basis of a little-known ODE solving technique sometimes known as the Taylor Series Method (occasionally Differential Transform). It allows an "extension" of Euler's Method to arbitrary order (using arbitrary precision arithmetic), by _calculating_ the higher derivatives rather than approximating them as in RK4 and friends.

Here is an open access link to just one of many papers on the subject: https://projecteuclid.org/euclid.em/1120145574

It includes a link to the actual software they used.

[EDIT] Obviously applying the technique above to dx/dt = x reproduces the Taylor Series in the article!

m4r35n357··on Ask HN: Git alternatives that aren't so complicated?
Before Git, branching and merging was a nightmare. People are using git to do much more complicated things than in the days of CVS/SVN.
m4r35n357··on Speeding up function calls with lru_cache in Python
Huh? He sped it up much more by rewriting as a loop . . .
m4r35n357··on Coronavirus: Dexamethasone proves first life-saving drug?
It was only ever a con, perpetrated by corrupt politicians.
m4r35n357··on Coronavirus: Dexamethasone proves first life-saving drug?
Just let them try! ;)
m4r35n357··on Quantum Matter Orbits Earth
The ISS is in free-fall, so that should be zero-g, not microgravity.
m4r35n357··on Why ‘playing hard to get’ may actually work
. . . and probably cannot be sustained indefinitely.
m4r35n357··on Gamow’s cyclist: a new look at relativistic measurements for binocular observer
If you like the article, here are some videos I made a while ago, showing what might be seen by the traveler in the twin "paradox" as she leaves and returns to base (click "show more" to see the terse descriptive text): https://www.youtube.com/playlist?list=PLvGnzGhIWTGR-O332xj0s...

One of them is a 3D "Tompkins" view : https://www.youtube.com/watch?v=4lZXFXWN37M&list=PLvGnzGhIWT...

View in 1080 rez to see the clocks etc.

m4r35n357··on We’ve built a towering pile of shite
It is the cost of making computers "user friendly" and providing a positive "user experience". Can't be done without layers of crap, it's a law of physics.

The alternative is to deal with computers how they naturally "want" to be talked to. Then life is simple, you just need _engineers_ to write the software, and to _train_ people to use it.

m4r35n357··on We’ve built a towering pile of shite
Yeah hitting the up arrow a couple of times then return is a real pain.
m4r35n357··on Postmodernism and Its Impact (2017)
The hippies.
m4r35n357··on How to Make this Moment the Turning Point for Real Change
The BBC is linking it now.
m4r35n357··on How to Make this Moment the Turning Point for Real Change
Possibly the article was considered too positive for some elements?
m4r35n357··on How to Make this Moment the Turning Point for Real Change
Then reflagged.
m4r35n357··on How to Make this Moment the Turning Point for Real Change
Now unflagged. Good.

Stallman right again shocker!

My desktop is a Raspberry Pi, you insensitive clod!
m4r35n357··on Black hole paradoxes reveal a fundamental link between energy and order
Nope. That is not what an event is: https://en.wikipedia.org/wiki/Event_(relativity)
m4r35n357··on Black hole paradoxes reveal a fundamental link between energy and order
Events are never curved!
m4r35n357··on Pros and Cons of Nim
Great to hear. Just hope they can resist the inevitable flood of "good ideas" and stick to their design.

[EDIT] recognized your nick from IRC a while back, my "good idea" is still to add support for 80-bit floats ;)

m4r35n357··on Pros and Cons of Nim
Nim currently in uber-cool phase. I love it.

After adding a million requested features it will end up bloated like all the others . . .

m4r35n357··on I won’t buy ebooks anymore
Yep, I have plenty of books dating back to the seventies (some even older). They are all still perfectly functional.

Not heard of a 50 year old epub or pdf yet, wonder if it will ever happen ;)

m4r35n357··on Ask HN: Is there still a place for native desktop apps?
Web last, please!
m4r35n357··on New Munich city government agrees to use open source software where possible
Bean counters prefer to pay others to "make those problems seem to go away".

That one took me a few seconds . . . ;)
