why do unix assembly files
use a .s extension?
someone asked me today,
and i didn’t know,
so i asked ken.
the .s is for source,
just like .o is for object.

I don't understand why people say git is hard to use. Look how easy it is to list all tags with their dates:

Personally, instead of reading blog posts that pretend Go vs Rust is some kind of zero sum game, I would much rather focus on ways that Go and Rust complement each other and can work well together. Like this post:

Seeing discussion of io/ioutil deprecation in various places.
To be clear: in Go, “deprecated” means only “there is a better, preferred way.” It does not mean “will break in the future.”

Keeping Go's git history nearly linear is one of the best decisions we made.
Looking at a GH repo that's all 'merge of this pull request' and PR commits are 'merge of my work branch with my PR branch'. SNR is near zero.
Branches can be a great tool, just not for every commit.

Thrilled that Go has popularized pprof, a fantastic cross-language tool!
Pprof was written by Sanjay Ghemawat in 2001, in C++ for C++. Moved to Perl, then Go. Open-sourced twice, once in google-perftools (little used) and once with Go. Still language-neutral and still improving.

Most obviously, if your study claims that C++ uses 34% more energy, 56% more time, and 14% more memory than C, it’s time to reexamine your assumptions. Approximately every C program is a valid C++ program, so C++ can’t lose, especially not that badly! 4/

Nice frame for “unsafe”:
> Go loses its memory safety guarantees if you write concurrent software. Rust loses its memory safety guarantees if you use non-trivial data structures. C++ loses its memory safety guarantees if you use pointers (or references).

At Google, we've made it very clear to the Go team that they need to worry about themselves and their families. Deadlines will be pushed back, features will be delayed, and that's OK.

Does the radical new architecture have all the old speculative execution vulnerabilities?
Asking for a friend.
We’ve taken the traditional CPU design and radically re-architected it. Intel Foveros, an advanced new packaging technology, allows us to stack chiplets in three dimensions – an industry first – and enables performance and efficiency in a package smaller than a dime.

Ever read a program and “This is full of bugs! How could it possibly have worked until now?”
The answer is almost always: because it was tested.
The inputs that mattered were tested, and bugs affecting *those* got fixed.
But new inputs find new bugs and require new fixes.

Who controls which code installs as part of your software? There’s only one acceptable answer: you.
‘npm install’ adds: everyone else whose code you depend on. Hence the colors and node-ipc attacks. It will get worse as dependency trees grow.
It doesn’t have to be this way.

This is an absolutely fair criticism - we have not handled the community process around dependency management well. The core Go team was not involved early or often enough for that process to lead to a smooth landing. As tech lead for Go, that was my fault, and I apologize.
