Golang Insiders

[image] New article: Go's Memory Allocator 🚀 How Go manages heap memory for thousands of goroutines. 64MB arenas → 8KB pages → spans → fixed-size slots. A three-level cache where the fast path is completely lock-free. 👉 #golang #go #runtime #programming

[image] New article: Inside Go's Runtime Scheduler 🚀 How Go runs millions of goroutines on a few OS threads. The GMP model, work stealing, spinning threads, and context switches that take only 50-100 nanoseconds (10-40x faster than OS threads). 👉 #golang

[text] Just refreshed the list of companies hiring Go engineers in 2026. - 58 companies total, I'll add more over time. - 63% of them are remote friendly - spans 15 industries Get the list here:

[text] I finally found time to update "my learning Go from beginner to senior" blog for 2026. It contains books, blogs and podcasts for you to level up your Go skills, wherever you are on your journey! Take a read and let me know what you think:
