Understand The Requirements For Medical Device Software Testing
Technology plays a vital role in all forms of modern healthcare, from simple personal monitoring devices like a step tracker to those in medical settings like critical care life support systems. Each requires software to enable it to run and deliver the expected service. Therefore, it is imperative that manufacturers have thorough and reliable medical device software testing in place.
It is estimated the market for such devices will be worth over US$ 455bn in 2022, and there’s the added fact that they impact the health of individuals who need to be confident they work as expected and won’t inadvertently cause harm. So, it isn’t surprising to see a regulatory regime that sets standards on how to test medical device software.

The Future of Headless Embedded Devices
The trend of hybrid and headless embedded devices disrupts many industries. According to a recent market study commissioned by the Qt Company, the future product design of embedded devices is heavily polarized depending on the industry. In some industries, 85% of respondents imagine that embedded devices will not have in-built screens anymore within five years. In other sectors, only 10% of respondents expect devices with in-built screens to disappear even within ten years. This blog post gives an update on opportunities and threats for a shift towards remote-controlled devices in different industries.

0027: preimp, framework, dotfiles and backups, links
I got as far as I could with the clj version.
The main obstacle is provenance. The main feedback from the essay was that it would feel much more natural with direct manipulation. Why write code to make a toggle button for the status of a todo? Why can't you just click on the status and change it?
Doing that requires tracking, for each value, where in the source code it came from so that we can map edits back to that location. Doing this in clojurescript seems very difficult. Clojurescript's strings and numbers are just javascript strings and numbers. There is no way to attach any additional information to them. I could put wrapper objects around all strings and numbers in the source code, but then existing functions won't work on them.
Performance is also an issue. I used preimp to build an accounting tool that we actually use, but we have to use it on my fancy laptop because on a $200 chromebook it takes multiple seconds to render a few months of transaction history.

How to display the presence and absence of nth-highest group-wise values in SQL | Opensource.com
While skimming through SQL to prepare for interviews, I often come across this question: Find the employee with the highest or (second-highest) salary by joining a table containing employee information with another that contains department information. This raises a further question: What about finding the employee who earns the nth-highest salary department-wide?
