The Dutch coastguard said on its website on Thursday that the cause of the fire was unknown, but an emergency responder is heard in a recording released by Dutch broadcaster RTL saying, "The fire started in the battery of an electric car". https://www.reuters.com/world/europe/carrier-ablaze-off-dutch-coast-carrying-almost-500-electric-cars-2023-07-28/ #EV #LithiumIon
Carrier ablaze off Dutch coast carrying almost 500 electric cars

The car carrier <a href="/world/europe/car-carrier-still-burning-off-dutch-coast-hunt-cause-begins-2023-07-27/">burning</a> off the Dutch coast since Tuesday night is carrying nearly 500 electric vehicles, ship charter company "K" Line said on Friday, significantly more than the 25 initially reported by the coastguard.

You need 4 main things to build better software:

☑ Precise designs (the specs) for your application, using formal methods

☑ The right programming language to implement the design plans

☑ Proper testing (Validate and Verify)

☑ Prediction to quantify the performance of your application

That's it.

#Subaru Outback still Subaru. Ready to go

Old work, but still valuable for anyone building or running Java applications.

This was a presentation I wrote during #OpenSolaris times, about Sun's Hotspot Java Virtual Machine. Includes a technical description on the HotSpot architecture, how to troubleshoot and trace your applications using DTrace for Java, and on top of these includes a simple method to help you configure the java virtual machine for your workloads and applications.

We all use testing to ensure our software works correctly in different situations. But testing alone is not enough as there is no way to run a program through every conceivable input. To build safe and secure systems, we need to use different methods. Enter formal methods.

Formal methods as a path toward better cybersecurity

Industry and government should accelerate adoption of formal methods to reduce software vulnerabilities and bolster security.

EU is planning to phaseout CO2-emitting cars starting with 2035. We already can see modern cars running more complex software than even airplanes! Are we heading for batteries on wheels expensive to fix but easy to dump? #digitaltrash #software #automotive #complexity
If you design and write software applications, build computer systems, or other type of hardware digital systems read Lamport's Specifying Systems and #HillelWayne Practical TLA+.

Software Lines of Code (SLOC) - a basic, useful metric to get a first idea how big, complex a project might be. Imprecise designs, ignoring the size of the project will contribute to produce bloat and insecure software. #software #softwaredevelopment
An asteroid large enough to destroy a city will pass between the orbits of the Earth and the Moon this weekend - luckily for us, missing both https://www.bbc.com/news/science-environment-65061818
Massive asteroid to pass by Earth on weekend

The unusually large space object will harmlessly bypass the planet this weekend.
