You think you know what your Java code does? You don’t. The #JIT rewrites it at runtime. Harshitha Popuri & @gireeshpunam trace how bytecode turns into native optimizations inside OpenJ9.

New post on the Python Insider blog from Ken Jin:
"Python 3.15's JIT is now back on track"
https://blog.python.org/2026/03/jit-on-track/
#Python #JIT #performance #python315
The Settings GUI in #konform #browser was in need of some love and is now having a refresh. Several new knobs, some shuffling around to make things more cohesive and less scattered, and some edits of hints to hopefully reduce potential for confusion.
New options for:
- First-Party Isolation
- Enhanced #tracking Protection tweaking in Custom mode (useful mostly for FPI users)
- #webrtc and ICE
- #dom Push and its optional network connection
- #jit features
- WebAssembly (#wasm)
- Geolocation
- WebGPU
- Async callstacks support
- Persisting of browser history
Hints and the "advanced" options expand when clicking the "?" for parent option.
Still a bit hesitant on where global toggles for #webgpu and #webgl belong. And perhaps configuration for cross-origin referrer could also move to Browser Privacy controls?
Otherwise feels like things are coming together - What do you think? Anything you're missing or that feels out of place?
