Hi Michael
Thanks for the answer. I was going for the updates, not the download, that
was already on the system. But I like to get the updates and the info on
them. I did not install the client, but I registered as a follower, so I

Hi Wim,
You could go the route of installing a git client, but should not need to.
Assuming you have your Android settings set to allow non-market
applications, you can install the latest package by hitting the 'raw'
url directly as listed below directly from your android. Failing
that, hitting
You can use github from the browser.

Hi Michael
(your name sounds Dutch to me)
One of the differences between Android 2.x and 4.x. I moved from 2 to 4
myself somewhere in the past on the same phone and still I have trouble
locating some functions.
I use the latest version 1.0.5. Is there a way to receive notifications on
update?
Sorry gentlemen,
The instructions I gave for enabling the keyboard were oriented to the
2.x android device I own. I explicitly targetted a low-numbered
version of android to guarantee the widest distribution.
Very glad you found it. Are you using the latest: 1.0.5 as available
on github?

All of the numbers I've reported are with a left argument to timex. The
argument I used was 10 for the 500s, and 1000 for the 50s, except my phone
where I had to use 1 to get stable answers for the 50s.

I also struggled a bit to find out how to enable the J Keyboard on my
HTC One S running JellyBean. In the end I discovered that once the
keyboard comes up in the J application, I can drag down the bar at the
top of the window to show the option to "Select Input Method".

I agree with your point, but the "benchmark" has always included
generating the matrix and that is typically a very small part of the
time and should be relatively stable (although I suppose inverting the
same "random" matrix over and over would remove some variation). Your
suggestion of using
Part of the reason for the variability is that you're generating a new
matrix each time and including the generation in your timing.
Something like this should give a more stable result:

Also, this form better allows you to run multiple timings to get a

Seems the Tegea 3 processor of the Nexus 7 uses ARMv7. Using the
appropriate version of J does cut execution times in half.
You are right, timings are practically identical to the iPad.

The android version you tested does not use hardware fpu. This is a
wise decision if it is intended to published in google play because,
unlike ipad, not all android devices have hardware fpu built-in,

I would suggest the App Store, on your iPad. Search for J programming
language. It's free.

I am curious to know what are the timings for iphone and ipad.
It is around 6 to 11 seconds on android depending on CPU.

Paul tested the best result (so far) for android is about 3.75 seconds.

From google, iphone 4 uses cortex-a8 and that cpu uses vfp-lite which
is 10 times slower than a regular vfp used in cortex-a9.

That's a nice speedup! It will be interesting to try the iPhone 5.
I'm curious if anyone has a timing from a generation 3 iPad, it may well
be faster than my iPad 2.

I believe Roger said he had timings from the IPSA days. He also said the
matix was considerably smaller. Did you ever get those early machine
timings?
