No, they are not mind maps.

A 2-week’s worth of readings means a longer than usual list, as usual.

This past week we were on holidays 🎉.

Days of fire Kafka and thunder SSL.

This Apache Spark feature has made us scratch our heads way too much.

I had a very entertaining week.

So, you want to debug some Go in VS Code.

A week on holidays (in-between jobs), where I read more books than articles.

Next week I start a new job 😮

This edition has an unusually low amount of big data.

This past week I’ve been on holidays in Cordoba.

Not sure if bug or feature, but this is hard to pull off.

This past week has been Data+AI Summit, so there are several new product announcements from Databricks.

This week is Data+AI summit week.

In which I write some easy Alloy code for a data model.

Not much to report.

Having to tweak a presentation for the Data+AI Summit time constraints has eaten all my disposable free time, hence the posting hiatus and this being relatively short.

I have spent a big deal of these weeks moving my notes from Bear to Obsidian.

Timezones and UTF are rocks you repeatedly hit in your data journey.

Looks like my mojo is coming back.

This edition is kind of strange: there’s more management than “code”.

My days are consolidating into piano, work, VR, piano, sleep, loop

This is not an overly long list, but covers a surprisingly large amount of topics.

Sweet, sweet holidays.

Sometimes I get an idea and I need to implement it.

Not sure what I did this past week aside from finishing a post: I read very little.

Lakehouse is the brand name for the underlying architecture of Databricks' Delta Lake: A data lake that is as performant as a data warehouse.

This is also a video-heavy edition, I keep chugging along my watch list with Glancer

Hive is arguably old.

The video edition

As promised, the numbering of these posts is now year-indexed.

Managing logging in Spark ain’t easy, and is even harder in managed clouds like Databricks or EMR.

Finishing and posting this got lost in a task manager reorganisation, it was due in June-July.

The last of 2020.

My reading list is at less than 10 items, so now my readings posts will hopefully look closer to watchings.

I have been on holidays this week, playing VR and preparing videos for an online Python event I co-organise.

This looks like a less hard technical edition than usual.

A relatively common type of query for time-based SQL tables is a find the gap query.

This is a short edition.

Adventures with Applescript, AWK and Things

Finished that post, now started the next.

This is the next instalment on my quest to read and help understand interesting papers in the data space.

I am having a very hard time finishing my summary of the RDD paper.

I have played a ton of virtual table tennis this week.

I have read quite a bit this week, I’m also preparing a summary of the RDD paper.

After reading the Snowflake paper, I got curious about how similar engines work.

I have dropped the Weekly from the title.

In the midst of chaos, there is also opportunity.

The one where Airflow messes with you.
