TU Darmstadt Moodle Wrapper
APK
Open Moodle links of the TU Darmstadt in the official Moodle app. Disclaimer Neither is this an officail project by the TU Darmstadt nor by Moodle. This is just started by me, a student at the TU Darmstadt, that has to much spare time. The Moodle at the TU Darmstadt regularly sends me mails with Moodle links to courses, forum posts and other content on Moodle. I always read those mails on my android phone, but clicking on those links from the mails results in opening the browser. I installed the official Moodle App, and wanted the links to open in the Moodle App. As this is not nativly supported by the Moodle App, I sat down and coded this little app, that redirects links to the Moodle App. After the app was finished, I wondered, if someone else could find this useful. The app is minimal and easy to use. Just install it, and all supported links can be opened in Moodle. Prerequisites You will need to have and android phone with at least Android 6.0 Marshmallow and the official Moodle App with at least version 2 installed. Which moodle links are supported? This app supports the folloing Moodle URLs (https only): moodle.tu-darmstadt.de (standard Moodle) moodle.informatik.tu-darmstadt.de (computer science Moodle) vorkurs.mathematik.tu-darmstadt.de/moodlevorkurs (Moodle for the mathematicans preliminary course) wwwdid.mathematik.tu-darmstadt.de/moodle (some other probably outdated Moodle installation I found) moodle-exam.tu-darmstadt.de (moodle installation for online exams) moodle.chor.tu-darmstadt.de (moodle of the TU choir) If the TU Darmstadt has any other Moodle URLs I should include, open an issue and let me know. How to uninstall the app? The app won't show up on your home screen. This is intended, as there is no need for a home screen icon. To uninstall the app, open your System Settings -> Apps -> search for "TU Darmstadt Moodle Wrapper".

One of the main changes introduced by the regulations is that all customers covered by the PVPC are grouped under the same toll rate called 2.0. TD, which replaces the previous three (the default rate 2.0 A, the night rate 2.0 DHA, and the electric vehicle rate 2.0 DHS).This new 2.0 TD rate has a time discrimination in three periods: peak, flat and valley that are defined according to the day of the week, the time of day and the geographical territory (different for Ceuta and Melilla).The App includes a tool that calculates and orders the cheapest time slots of the day (average prices) for a specific time interval. For example, it is useful to know the best time of day to run the washer and dryer consecutively.

ThreatScoopOnionChat
APK
# ThreadScoopOnionChat This version is a fork from " https://github.com/session-foundation/session-android ", enfocado en la privacidad. ## How Did ThreadScoopOnionChat Come About? I have always been a fan of privacy and security in communications, and I am constantly researching potential security breaches in messaging applications. ThreadScoopOnionChat emerged after the analysis of this blog "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/", in which several aspects are described as to why using Session is not recommended, and I wondered how it is possible that a foundation focused on privacy—with the grants and support it receives—has not been able to improve this protocol. I still do not understand the answer, since my resources are much smaller than those of a foundation compared to that of a person who is simply a fan of privacy and security. In this blog, certain problems were described: 1> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#insufficient-entropy-ed25519" 2> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#in-band-negotiation" 3> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#public-keys-aes-gcm" This is a forked version privacy focussed from Session.

Thumb-Key
APK
Thumb-Key is a privacy-conscious smart keyboard, made specifically for your thumbs. It features a 3x3 grid layout, and uses swipes for the less common letters. Its easy to learn, and designed for fast typing speeds. Instead of relying on profit-driven, privacy-offending word and sentence prediction for accuracy, as do most popular phone keyboards like Gboard and Swiftkey, Thumb-Key uses large keys with predictable positions, to prevent your eyes from hunting and pecking for letters. As the key positions get ingrained into your muscle memory, eventually you'll be able to appromixate the fast speeds of touch-typing, your eyes never having to leave the text edit area. This project is a follow-up to the now unmaintained (and closed-source) MessagEase Keyboard, which is its main inspiration.
