Dyalog '18 Videos, Week 7
Our stated goal has been to provide variety each week, and I’m happy to say that I have not been able to find any kind of theme in this penultimate set of presentations from Dyalog’18 in Belfast. Although the three technologies presented are all very useful, that is the only thing that they seem to […]
Dyalog '18 Videos, Week 6
Happy New Year – and Welcome to the 6th week of Dyalog ’18 video releases! If you enjoy geometry, 2019 starts with a couple of real treats; one which builds up to the use of complex numbers just before the end, and another which starts with them and moves on to Quaternions. Alternatively, if you […]
Dyalog '18 Videos, Week 5
We are releasing four talks this week from Dyalog ’18 in Belfast. Three of them focus on techniques for deploying APL applications across all the platforms supported by Dyalog APL, in particular Microsoft Windows, Apple macOS, and GNU Linux on x64 platforms (many tools will also work under IBM AIX and on the Raspberry Pi). […]
Dyalog '18 Videos, Week 4
This week is mostly a deep dive into the new world of storing source code in text files rather than workspaces and other “binary” formats. However, in case that is not your cup of tea yet, we can offer you another talk by Marshall Lochbaum, who presents more amazing algorithms to make the very widely […]
Dyalog '18 Videos, Week 3
The four presentations from Dyalog’18 that we are releasing this week address both the visible (user interface) and invisible (performance) parts of application design. Starting with performance: This quote was at the heart of the talk by our invited keynote speaker Martin Thompson. In order to write software which performs well, you need to have […]
Dyalog '18 Videos, Week 2
Each week until early January, we will be releasing a selection of recordings of presentations from Dyalog’18, which was held in Belfast at the end of October 2018. Last week we kicked off with the opening keynote talks and the prize ceremony and acceptance speech by the winner of our annual problem-solving competition. Just under […]
Welcome to the Dyalog '18 Videos!
Three weeks have gone by since we waved goodbye to the last Dyalog ’18 delegates in Belfast. We’ve had time to catch up on sleep, half of us have had colds and recovered from them. Jason Rivers and Richard Park have started mixing and improving the audio and video recordings, and we are ready to […]
Beauty and the Beast
Finally, the last accessory I ordered for my Raspberry Pi Zero (that’s the little red thing behind my keyboard) has arrived – an Acer 43″ ET430K monitor. The Zero won’t quite drive this monitor at its maximum resolution of 3840×2160 pixels, but as you can see, you get enough real estate to do real graphics […]
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| […]
