#java#nem#nem_blockchain
You can quickly build and run a NEM node using the NIS (NEM Infrastructure Server) project, which includes all necessary parts like core, deploy, peer, and nis modules. To build it, you need Java 11 or higher and Apache Maven. After building and testing, configure your node by placing property files in a folder named "staging" and start the node with a Java command allocating at least 6GB RAM. You can also set up a testnet node by creating a specific config file. This setup helps you run and manage a secure NEM blockchain node efficiently, supporting blockchain validation and network participation. Detailed docs and community support are available for help.

# The standard string repr for dicts is hard to read:
»> my_mapping = {'a': 23, 'b': 42, 'c': 0xc0ffee}
»> my_mapping
{'b': 42, 'c': 12648430. 'a': 23} # 😞
# The "#json" module can do a much better job:
»> import json
»> print(json.dumps(my_mapping, indent=4, sort_keys=True))
{
"a": 23,
"b": 42,
"c": 12648430
}
# Note this only works with dicts containing
# primitive types (check out the "pprint" module):
»> json.dumps({all: 'yup'})
TypeError: keys must be a string
