"dear beginners, please learn to use the debugger"
bold of you to assume that my program compiles successfully

[wurlin_murlin]

Debugging is the most valuable skill all engineers can learn at all levels of abstraction (maybe after "being passionate").

If you are staring at code, or administrating a network service, or supporting some complex distributed cloud behemoth, or reverse engineering weird vendor products and protocols -- the skill of picturing & isolating components and being familiar with the tools to do so (be that a debugger or whatever else helps you see what's actually happening) always makes life less painful.

I love using a debugger specifically for gameplay stuff where there are lots of different variables that may or may not be causing the issue and instead of writing loads of print statements and reloading I can just test lots of different things on the fly.

Stalin debugging: rasstrelyat that bug

[VanOri]

Debuggers are the holy grail of programming

[Cinarbayramic]

i just use it to measure which function takes the most time and optimise it

"nothing the g'old print debugging cant fix"

[Naburgondux]

Holy grail GDB, would've wasted much more hours than i should without it.

[darko_n]

GDB people could benefit by using some of them GDB GUIs but I can't assure you their quality.

"Never assume you know what the problem is"
and related: find and fix the real problem.

When searching for a problem, it tends to happen that you will find the symptoms of problem and it will be supereasy to just put an end to the effects caused by the bug instead of actually fixing the root cause.

Fix the real problem!

Can't be a coincidence that I spent 1 hour today because I forgot I copy pasted code that increment 'i' inside the for loop and inside the loop statement so I skipped half of the items...

non-debuggers when "Segmentation Error"

How much years of blood and sacrifice it takes to become beast Chad c++ coder

I use gdb for things but my goto is still printing and asserts

I just don't get the anti debugger stance and insistence on adding printf statements that seems to be prevalent among certain circles. It's like not using oscilloscopes and multimeters when debugging a complex circuit board and instead staring at the pcb and soldering LEDs onto random spots. When I was just starting out I didn't use debuggers, mainly because I had no idea what they could do for me and did not know how to use them effectively. Two decades later and the debugger has become an indispensable tool. Learn to use both, learn when to use which and learn how to debug efficiently. Logging and debugging are not mutually exclusive, they go hand in hand.

Hi LowLevelGameDev.
May I ask how you are handling different resolutions in your games?
Like for example, I have a 1440p monitor and my 2d pixel art game looks good. But my friend for example has a 1080p monitor so everything looks zoomed in on his machine.
How can I make it look the same on both resolutions without making it look scuffed.

Do you know any good resources to learn gdb? In my experience, Those old tools have very sparse resources.

[cameonn]

What font do you use? It looks awesome! (as subtitle)

[Cnastret]

I use neovim and I'm not leaving it. Guess I am going with gdb

[duchtnv]

I always ask my self is there a memory viewing tool for Linux like the one from visual Studio (maybe a Video about replacing visual Studio - removing Microsoft from your live)
