#Java

I've been teaching "Introduction to #Mobile Development" for 4th-semester students over the last years.

I've used #Android and #Java but got quite disillusioned with the Android development ecosystem (to call it a moving target would be a bit of an understatement).

So this year I tried out #Flutter, but that seems to have a rather steep learning curve for relatively inexperienced students... So off the top of your head(s), what would you recommend for this kind of course?

(Boost for reach!)

What could possibly go wrong? #DOGE to rapidly rebuild #SocialSecurity codebase.
A safe and proper rewrite should take years not months.
The project organized by #Musk lieutenant #SteveDavis, multiple sources who were not given permission to talktell WIRED, and aims to migrate all #SSA systems off #COBOL, one of the first common business-oriented programming languages, and onto a more modern replacement like #Java within a scheduled tight timeframe of a few months.

Gerade nach einer Diskussion getestet: Wenn man ChatGPT nach einer JPA Entity mit Lombok Support fragt, erzeugt es exakt die Code-Konstellation vor der alle Blogs zu dem Thema warnen – eine @Data Annotation an der Entity. Damit ist es ungefähr so gut wie Junior Developer die kein Google benutzen.

import lombok.Data; import lombok.NoArgsConstructor; import javax.persistence.*; import java.util.List; @Entity @Table(name = "person") @Data // Lombok generiert Getter, Setter, toString, equals und hashCode @NoArgsConstructor // NoArgsConstructor für JPA (Standardkonstruktor) public class Person { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id") private Long id;

A nice text from @meistermeier which classifies the role of the Spring Actuator in the Volkswagen hack and shows that Spring Boot does not provide default heap dumps in production.
The only thing I would add is that in our last Spring projects we used routing in K8S to ensure that the actuator endpoints could not be accessed from the Internet at all, but only from the K8S health check and localhost

There's plenty wrong with #Java, but after using it for a course it's pretty good for concurrency. Monitors make things so much easier than raw mutexes. No wonder Tanenbaum praised it in one of his books.

I'm working on enabling the #DigiPres parts of our org by making some of the #COPTR Tool Grid apps available securely in a managed #Windows environment - first cab off the rank is a #Java app with bundled #JRE, which won't play well with our env 😕

does anyone have experience using #maven & #jpackage as part of a build pipeline to create OS-native installers? my short-term target is a Windows MSI, but once that's in place the same pipeline should be able to spit out native installers for macOS (which we also use) & Linux (which we don't - yet 😈)

I'm at the point where I'm about to clone the repo & start tinkering 😫 but would much rather re-use something already built than figure it out from docs & example code...

#boost4reach pls 🙏
