You might be able to use FILE_FLAG_DELETE_ON_CLOSE, but this would likely require calling the Windows API functions directly.

Trino no longer depends on Hadoop/Hive for any of its data lake connectors. Removing that dependency was a huge effort.

Yeah, URL is from the first release of Java and should be avoided. You want to use URI instead.

New comment by electrum in "New PostgreSQL Interface for Cloud Spanner"

Procedures are very useful to enforce business logic in the database, rather than in the application. It’s like putting a higher level application-specific API on top of your database schema.

For Cockroach, it could help substantially with latency for multi-statement transactions, since the procedure could be executed on a database node closest to the leaseholder for the data. Executing a multi-statement transaction on the client means incurring per-statement latency between the client and gateway node, and between the gateway node and the leaseholder.

The H2 embedded database has compatibility modes for other databases, which seems helpful for testing, but ends up being incompatible in various ways for anything non-trivial. You end up fighting the compatibility and skipping useful native features of the target database, while still not having confidence that the code works on the target database.

We now use the awesome Testcontainers library (available for multiple languages) that makes it easy to launch the real database in a Docker container. Testing applications against multiple databases is now trivial.

This is part of the IntelliJ IDEA platform, so all of the JetBrains IDE products have it. I don’t use it often, since I normally rely on Git, but it’s saved me several times after I accidentally deleted a file or made a mistake with Git.

Even more confusing, the 404 on GET is caused by doing the HEAD when the object doesn't exist. Without the previous HEAD, the GET would usually succeed.

Tesla has a slider for the charge limit with 90%+ being designated as Trip and 50-90% as Daily. Even for a trip, I avoid charging above 90% because regenerative braking stops working when the battery is nearly full, which results in a substantial change to the way the car handles. You get used to one pedal driving and rarely having to use the brakes, so it's very unnerving for the car to not slow down rapidly when you let up on the accelerator pedal.

The indentation is removed at compile time, per the JLS: https://docs.oracle.com/javase/specs/jls/se15/html/jls-3.htm...

> Incidental white space is removed, as if by execution of String.stripIndent on the characters resulting from step 1.

The new stripIndent() method is provided as a convenience to developers.

IntelliJ shows you exactly where the block starts, so if you have a line with less indentation (causing the entire block to start at that column), it is easy to spot.
