Star it if you develop C++ to deploy to Graviton.

Made in Switzerland — now running everywhere.

BIG NEWS: My C++ Profiler GitHub Action now runs **natively on ARM64**!

No QEMU. No emulation. Full Valgrind + flamegraphs on:
• AWS Graviton
• Raspberry Pi
• GitHub’s official ubuntu-22.04-arm or ubuntu-24.04-arm runners

Example (ARM64 runner):

"
- uses: boxtob/[email protected]
with:
binaries: build/test
run-args: --verbose
"

Works out of the box. No hacks.

@github @cpp @valgrind Star it if you want C++ CI to be useful.

Feedback welcome!

Thread: I just open-sourced a GitHub Action that automatically detects memory leaks and CPU hotspots in C++ PRs.

No setup. Just add 3 lines.

@github @cpp @valgrind Supports:
• Valgrind (memcheck/callgrind)
• gperftools (CPU sampling)
• Flamegraph PNG
• Fail on leak

5/6

[Nikolaos Gerontidis @nikger]

It uses Valgrind + gperftools under the hood.

Fails PRs on leaks. Shows clickable annotations. Uploads flamegraphs.

Works with any binary, any deps, any args.

I have a mental illness that makes me think that people will change their minds if I present the correct arguments with the appropriate facts and data.

@donalt So that’s the “Alt” strategy , got it 🫡

[Nikolaos Gerontidis @nikger]

@donalt And how will you make more money this cycle if eth doesn’t run ?

[Nikolaos Gerontidis @nikger]

@skaigr hahah

[Nikolaos Gerontidis @nikger]

@MKBHD Very hard! Especially if there are “famous” people like you advertising it 😀
