    SurvivalManual

    SurvivalManual

    Libre Survival Manual for Android with offline in mind

    ...But it doesn't have to be used only in emergency situations, it can also be useful for outdoor trips, walks, camps, and learning about nature and yourself truly. This is not only fun, but you can also train skills (fire, build shelter, ...) that you may need in a catastrophe. Some things work best with practice in a relaxed environment, so you also have time for some experiments. The refugees also are welcome to use this application to prepare and guide you for your dangerous journey. Although I hope that we as humans will come to feel and stop wars and end climate injustice so that people do not have to flee and be afraid.

    Kamon Telemetry

    Kamon Telemetry

    Distributed Tracing, Metrics and Context Propagation for applications

    ...With Kamon Telemetry you can collect metrics, propagate context across threads and services, and get distributed traces automatically. The best way to get started is by following our installation guides and taking it from there. Have fun with Kamon. Monitor your backend applications, fix performance issues, and get alerted when problems happen. All without being a monitoring expert. Everybody starts monitoring with logs because they are there by default. Just connect to your server and start tailing. But logs have a hard time showing you the overall response times for your application, or whether certain calls to the database are happening in sequence or parallel (among a million other things).

    Splitties

    Splitties

    A collection of hand-crafted extensions for your Kotlin projects

    ...These libraries are intended to reduce the amount of code you have to write, freeing code reading and writing time, so you can focus more on what you want to build for your users (even if you're the only one), or have more time to have fun. This project is named "Splitties" because it is split in small modules, distributed as independent libraries, so you can add only the ones you need to your project/module, helping reduce the size of the final binary that users' devices will need to download and keep in the limited storage (BTW, everything is limited). Some Android targeting modules have content similar to what Anko offers.

    evil.sh is a shell script collection of “subtle and not-so-subtle shell tweaks that will slowly drive people insane,” as the README states. It is a playful (some might say mischievous) set of shell customizations, aliases, overrides or environment changes intended for fun (or prank) usage—e.g., customizing the shell prompt, redirecting commands, changing behaviors of common commands in subtle ways. The repository warns that it is purely for entertainment and that the author is not responsible for its usage. Because it’s simply sourced (e.g., in .bash_profile), the tweaks affect your shell session directly. ...

    Hibersap

    A Java library to communicate with SAP

    ...It defines a set of Java annotations to map SAP function modules to Java classes as well as a small, clean API to execute these function modules and handle transaction and security aspects. Hibersap's programming model is quite similar to those of modern O/R mappers, significantly speeding up the development of SAP interfaces and making it much more fun to write the integration code. Under the hood, Hibersap either uses the SAP Java Connector (JCo) or a JCA compatible resource adapter to communicate with the SAP backend. While retaining the benefits of JCo and JCA like transactions, security, connection pooling, etc., developers can focus on writing business logic because the need for boilerplate code is largely reduced.
