Equational

Let it be known that when I significantly change jobs I buy a new laptop. Which is why I find myself typing this on the Lenovo x220 I purchased for 120CHF at the local used hardware shop here in Oerlikon. Once I have finished to set it up (it already has new SSD, RAM and battery pack for an extra 200CHF), my 13" MacBook will be mostly my work computer (for my technical advisor job). Here is a picture of it. If you care why I chose an x220 and the switch back to linux, then do read on. The thinking goes as follows: Leaving Apple: In 2015 I chose MacBooks as standard laptop for engineers at Elevence, really because when you get acquired, you need to be already halfway enterprise. Yet the choice became a pain because of the extra effort needed to get development tools running on Mac OS. Then in 2016, Apple stopped being developer friendly by killing touch typing with the Touch Bar, and worse by removing the Escape key. (And yes, of course you can reassign it, but that is n...

I bring up this past in this blog to cheer excellent individuals and a great team, and give you insights into how QT and Actant led me to co-found Elevence and develop a unique smart contract language (then acquired by Digital Asset). First the cheering: Still now Actant software is known to be the fastest non-proprietary derivative trading software. And while I don't have the numbers, I could well believe that they compete well with proprietary derivative trading software on classical hardware (meaning CPUs and not FPGAs)...
