Office 365 and Exchange gateway Ever wanted to get rid of Outlook ? DavMail is a POP/IMAP/SMTP/Caldav/Carddav/LDAP Exchange and Office 365 gateway allowing users to use any mail/calendar client (e.g. Thunderbird with Lightning or Apple iCal) with an Exchange server, even from the internet or behind a firewall through Outlook Web Access. DavMail now includes an LDAP gateway to Exchange global address book and user personal contacts to allow recipient address completion in mail compose window and full calendar support with attendees free/busy display. The main goal of DavMail is to provide standard compliant protocols in front of proprietary Exchange. This means LDAP for address book, SMTP to send messages, IMAP to browse messages on the server in any folder, POP to retrieve inbox messages only and Caldav for calendar support. Thus any standard compliant client can be used with Microsoft Exchange. DavMail gateway is implemented in java and should run on any platform. Releases are tested on Windows, Linux (Ubuntu) and Mac OS X. Tray does not work on MacOS and is replaced with a full frame. Tested successfully with the Iphone (gateway running on a server).

A geteduroam client for Linux. Geteduroam simplifies the process of connecting to eduroam Geteduroam is a proposed extension of the NREN T&I services, aimed at increasing the update and use of eduroam by students and faculty members. The idea is to do away with the need for separate eduroam user accounts, and instead use national federated Id (through eduGAIN such as SURFconext, Swamid, FEIDE, HAKA, etc) to automatically generate eduroam login credentials in form of client certificates as needed. In addition, geteduroam will deliver apps for user devices that will automatically install and configure eduroam. Eduroam is seen as one of the most successful NREN services. eduroam service deployment is extensive, with nearly every campus in Europe having an eduroam Wi-Fi network. However, in terms of users who have eduroam installed correctly on their devices, the uptake is much less. This is believed to be the results of 1) users need a separate eduroam account, 2) users need to install and configure this account on their device, 3) the need to do so become apparent to users only when they are away from their home institution. At the time eduroam was developed, there was no simple way around this. Today, with the widespread adoption of federated Id and the global collaboration of such Id’s under eduGAIN, it is possible to develop what is essentially a more modern way on managing and deploying eduroam for users. This is the objective of the geteduroam project. Additional information:Developer: geteduroamLicense: BSD-3-ClauseVersion: 0.14

Private logbook with AI assistants Lotti gives you a private logbook and a staff of personal AI assistants to go with it. Record your day the way it actually happens — tasks, tracked time, voice notes, transcriptions, journal entries, habits, and health data — and long-living agents read what you record, keep it summarised, remember the context you would otherwise lose, and propose the next step. Agents suggest, you decide: every proposed change waits for your approval, with one small exception — an initial title or language for an otherwise empty task. All of it happens on your own devices. No server ever holds your data in readable form: multi-device sync is end-to-end encrypted, and the relay between your verified devices holds only ciphertext — not forever, and nothing depends on it keeping anything. There is no telemetry. On capable hardware the AI models run locally too, so your data never has to leave the machine; on lighter hardware, or to save battery, you route inference — per life category — to a cloud provider you choose. Your logbook is ordinary SQLite on your own disk with attachments in ordinary files beside it, readable without Lotti, so there is nothing to export and nothing to unlock. Under the hood, sync runs over Matrix using Vodozemac (Rust) for Megolm crypto; the homeserver relays only ciphertext between your own devices, and encryption keys reach only devices you have verified. A new device catches up because your other devices re-send history, not because a server stored it. Get support and join the Lotti community on Discord via the Contact link. What it does: Long-living AI agents (mission, soul, report directive) that read your logbook, propose changes, and only act after you approve Two-database architecture: a strict separation between your facts (the user database) and what the agents think (the agentic database), enforced on disk Run reasoning-capable models locally via oMLX or Ollama (e.g. Qwen 3.6 35B A3B, a Mixture-of-Experts model with ~3B active parameters) — or use Gemini Flash, OpenAI, Anthropic, Mistral, Melious.ai, or any OpenAI-compatible cloud provider, on a per-category basis Local voice transcription with Whisper or Voxtral; cloud transcription via Gemini, OpenAI, Mistral, or Melious.ai AI-generated cover art for tasks via Nano Banana Pro on Gemini, OpenAI, or Qwen, and Flux on Melious.ai Both the logbook and the agentic state sync end-to-end encrypted Habit tracking with success/fail/skip completion types, custom measurables, and dashboards Bring-your-own API keys for cloud providers, choosing per category where inference happens — EU-hosted, US, Chinese, or entirely on your own machine Usage & Impact: tokens and requests for every cloud AI call, broken down by category and model, plus cost, energy and CO2e wherever the provider reports them (currently Melious); local inference is not measured Time recording kept separate from planning, so what you meant to do and what actually happened stay distinct facts Additional information:Developer: Matthias NehlsenLicense: GPL-3.0-onlyVersion: 1.1.19

Match tiles and clear the board Single-player tile-matching game, commonly known as Mahjong solitaire. Tiles are stacked on the board at the start of the game. The goal is to remove all the tiles in as little time as possible. Select two matching tiles and they will disappear from the board, but you can only select a tile if there is an empty space to its left or right at the same level. Be careful: tiles that look alike may actually be slightly different. You can choose from a variety of starting layouts, some easy and some difficult. If you get stuck, you can ask for a hint, but this adds a large time penalty. Additional information:Developer: The Mahjongg TeamLicense: GPL-3.0-or-laterVersion: 51.1

GNU PSPP is a program for statistical analysis of sampled dataGNU PSPP is a program for the statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functionality that PSPP currently supports is in the core package. PSPP is a stable and reliable application. It can perform descriptive statistics, T-tests, anova, linear and logistic regression, measures of association, cluster analysis, reliability and factor analysis, non-parametric tests and more. Its backend is designed to perform its analyses as fast as possible, regardless of the size of the input data. You can use PSPP with its graphical interface or the more traditional syntax commands. A brief list of some of PSPP's features. Support for over 1 billion cases Support for over 1 billion variables Syntax and data files which are compatible with those of SPSS A choice of terminal or graphical user interface A choice of text, postscript, pdf, opendocument, html or TeX output formats Inter-operability with: LibreOffice, Apache OpenOffice, Gnumeric and other free software Easy data import from spreadsheets, text files and database sources The capability to open, analyse and edit two or more datasets concurrently A user interface supporting all common character sets The user interface has been translated to multiple languages Very fast statistical procedures, even on very large data sets No license fees and no expiration period No unethical “end user license agreements” A fully indexed user manual Freedom ensured; It is licensed under the GPLv3 or later Portability; Runs on many different computers and many different operating systems PSPP is particularly aimed at statisticians, social scientists and students requiring fast convenient analysis of sampled data.
