Yes

Big guy with a club:

Josuttis's books are normally pretty good, lots of examples and a clear explanation of why you might want to use something, but oof that looks akin to a kick in the essentials.

Even if you've no other reason to update to C++20, the fact that if constexpr gets rid of half the things you'd previously need to use SFINAE for, and concepts gets rid of the other half, makes it well worthwhile. Amazing how much it stops hurting when you stop doing ridiculous things.

I see someone finally embraced the fact that C++ templates are Turing-complete and you don't really need much of the rest.

That book looks as old as the language itself

y = mx + b

It's algebra. It's linear. 😬

I solved it. Answer hotdog

you got to use numbers? i'm so jealous. we had to use matrices of variables when i learned it

One time at work I was trying to work out a least-squares fit using linear algebra.

I have no background knowledge in linesr algebra, it felt like drawing a pentagram on the floor and chanting in backwards Latin.

That's not a fair example, I know what linear algebra is but can't tell what's going on.

Change of basis would be my guess, but that's pretty basic.

You could've provided something far worse, like a manual construction of the Jordan normal form of a large matrix.

EZ

You've officially lost it.

Thats not too bad. It just takes up a lot of space. Good thing I do my maths on an android tablet

The only thing i understand from that book is the title.

I'm going all-in on transonic fluid dynamics. All the joy of nonlinear acoustics, with a little navier stokes as a treat.

Do your CCIE and come back to me.

And for what it's worth, I did my BSc.Eng in Electrical too.

Then it's not compatible with the installed vm.

This almost never happens, unless you do very niche things or have unrealistic expectations from your file system.

Niche things include using obsolete cyphers for net communication or running java code on the ibm mainframe, not something you do day to day.

Java has changed a lot since Java 8. Here's a 3-line HelloWorld.java compatible with Java 21+:

void main() {
    System.out.println("Hello, World!");
}

Theres always Kotlin, which is like Java but for humans

Hahaha.. man you have a whole life ahead of you.

1. Java should not be used for game engine design. Stop-the-world events and poor shaders support do not help.

2. JVM eats as much memory as you give it, so try playing with -Xmx param

Is that why there's like 27 languages that are based on the same jvm?
