Ask HN: How do I improve our data infrastructure?

I was just hired as the first permanent data scientist in a big corporation. They’ve previously relied on consultants to build the infrastructure and the data science pipelines. We’re still around 10 people in the team.

The code is not pretty to look at, but this is not our biggest problem. We inherited a weird infrastructure: a mix of files in HDF5 and Parquet format dumped in S3, read with Hive and Spark.

Here are the current issues:
  • The volume does not require a solution that is this complex (we’re talking 100Gb max accumulated over the past 4 years)
  • It’s a mess: every time we onboard a new person we have to spend several days explaining where the data is.
  • There is no simple way to explore the data.
  • Data and code end up being duplicated: people working on several projects that require the same subset write their own transforma

Ask HN: How to learn best practices when you have no one to teach you?

I am currently working for a startup and am one of 3 developers. Most of my work revolves around building the API in Node + Express as well as some small projects with MongoDB. The other developers don't really assist me since they have their own projects to work on, and, honestly, they have less experience and knowledge than I do.

So my question is: What is the best way for me to go about learning best practices in API development, or using MongoDB, or even just being a better software developer in general?

Ask HN: How to talk like a leader, not like an engineer

I am a technical manager and currently in a leadership role. My manager who is an executive, keeps telling me“ don’t talk like an engineer, talk like a leader” when I go to him for any people or operational Issues. I always see from an engineer lens and possibly missing leader or executive perspective. How do I develop or change the way I talk as a leader. Did any one face this issue in the transition. Any pointers can be of great help.

Ask HN: How to create a service similar to Patreon?

I'd like to create a service similar to Patreon, I know how to do the technical side but not so sure about financial side: how do I charge users to send the funds to other type of users (creators), while subtracting a small percent? How does it need to be set up from the POV of financial compliance? Can it be reported as "payment to support Creator xyz" without a specific product? Does the company need to register as a bank or something similar to a bank? Financial services company? Where can I find some relevant resources, and how can I narrow down my research so that I don't have to read everything about all types of financial services but only more or less relevant info?
