I’ve recently started my journey with Apache Flink. As I learn certain concepts, I’d like to share them. One such "learning" is the expansion of array type columns in Flink SQL. Having used ksqlDB in a previous life, I was looking for functionality similar to the EXPLODE function to "flatten" a collection type column into a row per element of the collection. Because Flink SQL is ANSI compliant, it’s no surprise... - Source: dev.to / 6 days ago

You should let the Apache Flink team know, they mention exactly-once processing on their home page (under "correctness guarantees") and in their list of features.

Data scientists often prefer Python for its simplicity and powerful libraries like Pandas or SciPy. However, many real-time data processing tools are Java-based. Take the example of Kafka, Flink, or Spark streaming. While these tools have their Python API/wrapper libraries, they introduce increased latency, and data scientists need to manage dependencies for both Python and JVM environments. For example,... - Source: dev.to / about 2 months ago

Other stream processing engines (such as Flink and Spark Streaming) provide SQL interfaces too, but the key difference is a streaming database has its storage. Stream processing engines require a dedicated database to store input and output data. On the other hand, streaming databases utilize cloud-native storage to maintain materialized views and states, allowing data replication and independent storage scaling. - Source: dev.to / 4 months ago

Also, this knowledge applies to learning more about data engineering, as this field of software engineering relies heavily on the event-driven approach via tools like Spark, Flink, Kafka, etc. - Source: dev.to / 5 months ago

Anecdotally, I gave Dvorak a try and became somewhat proficient, but ultimately reverted back to QWERTY for one reason: keyboard shortcuts! Control-C|V|Z are all transformed into either two-handed shortcuts or right-handed shortcuts. In either case, I can't copy/paste while selecting text with the mouse (since I'm right-handed). I now use Colemak (https://colemak.com/) which doesn't have this issue and I'm quite... - Source: Hacker News / 12 months ago

Like, well, the original US layout, or Colemak. Suddenly, all those "hard-to-type" special characters and shortcuts start to make sense... Source: about 1 year ago

I started out using colemak.vim from the https://colemak.com webpage. Rather quickly I found that there were some things that I didn't like about the configuration, so I started modifying it. Eventually I had enough changes that I uploaded a fork of the configuration:. Source: about 1 year ago

Lets change all new keyboards to the Colemak layout, and change the order of the Alphabet to match. Source: about 1 year ago
