Welcome to HIVE. I look forward to what you have to say about coding for HIVE. I think the HIVE Tutorial on hive.io builds in too many dependencies.
Since you are writing about coding in HIVE. I assume that you are already familiar with the platform. I checked your account on HiveBlocks.com
https://hiveblocks.com/@learncode
HiveBlocks.com said that you had 0 HIVE POWER. Hive Power determine the resource credits for your account and you need resource credits so that you write posts and comments.
To get over this problem, I gave your account a 15 HP delegation. That should give you enough credits to write 16 posts. The credits refresh over a 5 day period; So, this should be enough to power the account.
