+## Development
+### Python setup
+```bash
+cd python
+python setup.py develop
+```
+* cython: use `cython --cplus -a  pyfury/_serialization.pyx` to produce an annotated
+  html file of the source code. Then we can analyze interaction between
+  Python objects and Python’s C-API.
+
+* Debug
+  https://cython.readthedocs.io/en/latest/src/userguide/debugging.html
+```bash
+FURY_DEBUG=true python setup.py build_ext --inplace
+# For linux
+cygdb build
+```
+
+### Debug Crash
+Enable core dump on Macos Monterey 12.1
+```bash
+ /usr/libexec/PlistBuddy -c "Add :com.apple.security.get-task-allow bool true" tmp.entitlements     
+codesign -s - -f --entitlements tmp.entitlements /Users/chaokunyang/anaconda3/envs/py3.8/bin/python
+ulimit -c unlimited
+
+python fury_serializer.py
+ls -al /cores
+```
+
+## Profiling
+### C++
+```bash
+# Dtrace
+sudo dtrace -x ustackframes=100 -n 'profile-99 /pid == 73485 && arg1/ { @[ustack()] = count(); } tick-60s { exit(0); }' -o out.stack
+sudo stackcollapse.pl out.stack > out.folded
+sudo flamegraph.pl out.folded > out.svg
+```
