That seems to only be for the Java code
How fast though is Java versus other languages? A show and tell page has submissions in Rust, C#, Go, Python, PostgreSQL, Python, C, C++, and more. These are hard to compare with one another since they have been run on different hardware, but there are some impressive results, including one under 5 seconds done with C on an AMD laptop, and a C# solution that runs in 5.3 seconds on a Core i5-12500 with 6 cores.
Sure if it fails completely it will, but it doesn’t catch everything. Here’s a related story I have:
At work we had a bunch of Lenovo X1 Carbons running windows that would have the usb-c ports die seemingly randomly on users which was a big problem since that’s also the charging port. There never seemed to be any similar root cause connecting the incidents and Lenovo’s support wasn’t any help. Our entire company is remote but luckily we had onsite support so for a while they would just come by and replace the whole motherboard each time.
Finally one day while scheduling a repair the support guy I was talking to just said, “Oh I’ve seen this before. It’s just a bad update and resetting the CMOS battery by putting a paper clip in this hidden hole fixes it.” We had the user try it out and the ports worked fine again. Apparently they had run some windows updates that failed silently and were causing the hardware issues.
From then on any time a user has had a hardware issue we can’t figure out we just have them try the reset and it has worked every time. This only happens probably 3-4 times a year but we only have less than 40 of these machines so not an insignificant amount.
