Samsung's next flip phone might be tough to tell apart from last year's Galaxy Z Flip 7. As 9to5Google points out, leaked images and specs for the upcoming Galaxy Z Flip 8 shared by WinFuture are nearly identical to Samsung's current flip phone. According to the leak, Samsung is not planning to upgrade the Z […]

I've been hearing the word "harness" thrown around a lot lately. I assumed it just meant "the IDE" or...

Vital Signals promises its algorithmic blood pressure monitoring ring will reshape how we live with hypertension and other cardiac conditions

The very common way we know to compile a C++ program is by running the following command: g++ filename.cpp -o filename Talking in terms of stages of optimized compilation, this method is the basic one — we can say stage 0, also written as: g++ -O0 filename.cpp -o filename There are a few more, from zero to three. Let's talk about these ways of compilation. 1] -O0 : No Optimization (Default) Fast compile time. Every variable gets a real stack slot; nothing gets reordered or removed. 2] -O1 : Basic Optimization Some dead code elimination. Simple register allocation. 3] -O2 : 'Standard' Optimization Register allocation. Dead code elimination. Inlining small functions. Loop unrolling and vectorization. Constant folding/propagation. Does not enable optimizations that trade accuracy/safety for speed. 4] -O3 : More Aggressive than -O2 Sometimes faster, sometimes not. Can hurt cache performance. Other than this, there is also a space-optimization option. 5] -Os : Optimization for Size Instead of Speed The command to use these optimizations is as follows: g++ -O2 filename.cpp -o filename Remember, in -O2 the "O" is a capital letter, not a zero — the same applies to the other optimization levels. If you don't know what's going on, or you just wish to compile C++ files the way developers do, use the following standard command: g++ -O2 filename.cpp -o filename
