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 […]
Rencontres Dyalog APL 2016 – Paris, France
It is really good to see APL events come back to life! In April of 2014, we witnessed the re-birth of SWEDAPL, which had been dormant for some time – but now meets twice a year and is perhaps the most vibrant APL meeting on our circuit, with many young developers developing new products and […]
FinnAPL Forest Seminar 2016
Finns probably have better reasons to look forward to spring more than most of us: not only does it get much easier to keep that hole in the ice open, it is time for the annual FinnAPL Forest Seminar! This year, just under 20 of us gathered for two days (Thursday March 10th and Friday […]
Happy New Year from the CXO!
To all our existing users, business partners and friends we have not yet met: Happy New Year from everyone at Dyalog – we hope that we can be of service to you in the year(s) to come! But what – or who – is a CXO? Well, according to Wikipedia, a chief experience officer (CXO) is the […]
SWEDAPL Meeting in Malmö, November 11th 2015
The November cycle of APL User Meetings is kicking off; the SWEDAPL meeting in Malmö was first this year, holding a meeting at the top of the famous Turning Torso in Malmö. Since it was just a short trip from our Danish office, Dyalog was represented by Gitte Christensen, Bjørn Christensen and Morten Kromberg – […]
Over the Moon with Selenium
Over the years, I have become more and more reluctant to write code without good regression tests – 35 years of software development have taught me that it is just too dangerous! Regression testing of user interfaces has always been difficult, but for the last few weeks I have been working with technologies that put […]
Response to Name Colouring for Dfns
This post contains comments to John Scholes’ post on name colouring; please continue to post any further comments with the original post. This is a very interesting topic – as the discussion has already showed, there are many different needs. It seems to me that some of the suggestions that have been made are forms of highlighting […]
