+2. **File Upload Errors**
+   ```bash
+   # Check permissions
+   ls -la /var/lib/fixture-daemon/uploads
+   
+   # Check disk space
+   df -h
+   ```
+
+3. **Daemon Won't Start**
+   ```bash
+   # Check logs
+   journalctl -u fixture-daemon -n 50
+   
+   # Test configuration
+   python daemon.py start --foreground
+   ```
+
+4. **Permission Denied**
+   ```bash
+   # Fix ownership
+   chown -R fixture:fixture /var/lib/fixture-daemon
+   
+   # Fix permissions
+   chmod 755 /opt/fixture-manager
+   ```
+
+### Debug Mode
+```bash
+# Run in debug mode
+export DEBUG=true
+python daemon.py start --foreground --config development
+```

+
+## Performance Optimization
+
+### Database Optimization
+- Connection pooling with 10 connections
+- Query optimization with proper indexing
+- Prepared statements for security
+- Transaction batching for bulk operations
+
+### File Upload Optimization
+- Chunked uploads for large files
+- Concurrent upload support (configurable)
+- Progress tracking with minimal overhead
+- Automatic cleanup of failed uploads
+
+### Caching Strategy
+- Session caching with Redis (optional)
+- Static file caching with Nginx
+- Database query result caching
+- API response caching for read-heavy endpoints
+
+## Security Considerations
+
+### Production Deployment
+1. **Change Default Credentials**: Update admin password immediately
+2. **SSL/TLS Configuration**: Enable HTTPS with valid certificates
+3. **Firewall Configuration**: Restrict access to necessary ports only
+4. **Regular Updates**: Keep system and dependencies updated
+5. **Backup Strategy**: Implement regular automated backups
+6. **Monitoring**: Set up comprehensive monitoring and alerting
+
+### Security Best Practices
+- Regular security audits

+create a new python project composed by 3 main interacting programs, start to write the first one, a daemon, to be run on a linux server exposed to internet implementing a web dashboard and a RestAPI with authentication, connect to a mysql database. The dashboard offer a csv file or an xlsx file upload and parsing, the upload form will call this file "Fixture",   where the fixture data contain the following columns: "Match #","Fighter1 (Township)","Fighter2 (Township)","Venue (Kampala Township)" and a dynamic list of other optional colums that from now on i will refer as "outcome results". the parsing will populate a mysql database, connection data is fetched from a configuration file, with a table where "Match #" is an integer, all the other mandatory data is a varchar255, and all the optional columns will be stored in a separate table with an id reference to the first table row id (autoincrement), a column "result" as varchar255 and containing the file upload optional column name, and a column "value" containing a float number with 2 digits precision. The first table will contain also the following columns that are NULL by default: "start time" ad datetime, "end time" as datetime, "result" as varchar255, and filename as varchar1024, file sha1sum as varchar255, and a fixture id unique for every fixture upload. When uploaded a fixture file, the dashboard should ask to upload a zip file ( large file upload here with progress bar ) for every row inserted in the database from the fixture file, when upload is done calculate the sha1sum of the zip file, and update the database with the file name and sha1sum. Only when the zip file is uploaded and the database update with sha1sum, then the record in the database is "active", you can use a flag in an additional column for it. Also create the SQL script to create the tables of the database.
