Charting Reaction Times on the Raspberry Pi
Earlier this week I collected some reaction timer data on my Pi using the BBC micro:bit as an input device. I only produced an “ASCII art” chart at the time: times←ReactionTimer.Play times 251 305 294 415 338 298 294 251 378 ReactionTimer.AsciiChart times 425| 400| * 375| * 350+ 325| * 300| […]
micro:bit Reaction Timer in APL on the Pi and BBC micro:bit
I have a bit of a cold today, so I decided that instead of hopping in an icy car and driving to the office in order to spend the day drinking coffee and answering e-mail, I should stay at home, turn up the radiators, make lots of tea (with honey!) and have some fun writing […]
Morse Code – Revisited using the BBC micro:bit
As mentioned last week, I have found a new way to provide a front end processor for my Pi, the BBC micro:bit. This week, I have started putting the new system through its paces: The microbit class in our GitHub repository has been beefed up to make it more resilient in the case where serial […]
Raspberry APL Pi and Python on the micro:bit
A couple of years ago I spent many happy hours writing APL code to control robots which each embedded a Raspberry Pi. It was fun but it was a bumpy ride – my interest eventually faded when I discovered that it was just too difficult to make sense of raw accelerometer data, which I was […]
Dan Baronet
We do not know the details, but Dan’s luck ran out this week. On Tuesday, as he headed South from Nevada into California, en route to Mexico on the first leg of a four month motor cycle adventure to South America, something went wrong … Dan lost control of the bike and collided with a […]
Snapshot blog from the last day at Dyalog’16 in Glasgow
#Dyalog16 – Vibeke Ulmann So we have come to the last blog from this year’s Dyalog User Conference. This is going to be a short one – as I can’t possibly do justice in words to some of the presentations we had Thursday morning. Gitte Christensen started off the morning by giving us a run […]
APL50 – celebrating the 50th Anniversary of the APL language

Cooking with Dyalog – Kai Jaeger (APL Consultant) and Stephen Taylor (Equiniti Claybrook)
#Dyalog16 – Vibeke Ulmann The presentation today was centred around the fact that many software programmers – and especially those who programme in Dyalog APL – have been involved in their applications for many years. Hence, they have not had to consider how to get from ‘beautiful code’ to a scenario where they have to […]
