An Emacs theme inspired by Plan 9's Acme & Sam Editor. As of 19. June 2020, it is available as MELPA package.

Interesting blog written in org-mode, using https://github.com/bastibe/org-static-blog, written by Bastian Bechtold https://bastibe.de/

Open-source hard- and software for two-factor authentication.
I need to test them and want to understand the differences between versions 1 and 2. The articles

Org-roam is a solution for effortless non-hierarchical note-taking with Org-mode. With Org-roam, notes flow naturally, making note-taking fun and easy. Org-roam should also work as a plug-and-play solution for anyone already using Org-mode for their personal wiki.

Solid (https://solid.mit.edu/)  was created by the inventor of the World Wide Web, Sir Tim Berners-Lee. Its mission is to reshape the web as we know it. Solid will foster a new breed of applications with capabilities above and beyond anything that exists today.

Solid (derived from "social linked data") is a proposed set of conventions and tools for building decentralized social applications based on Linked Data principles. Solid is modular and extensible and it relies as much as possible on existing W3C standards and protocols.

Within the Solid ecosystem, you decide where you store your data. Photos you take, comments you write, contacts in your address book, calendar events, how many miles you run each day from your fitness tracker… they’re all stored in your Solid POD. This Solid POD can be in your house or workplace, or with an online Solid POD provider of your choice. Since you own your data, you’re free to move it at any time, without interruption of service.

Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0) or compress most files more than bzip2 (lzip -9). Decompression speed is intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 from a data recovery perspective. Lzip has been designed, written and tested with great care to replace gzip and bzip2 as the standard general-purpose compressed format for unix-like systems.
The lzip file format is designed for data sharing and long-term archiving, taking into account both data integrity and decoder availability:
- The lzip format provides very safe integrity checking and some data recovery means. The lziprecover program can repair bit flip errors (one of the most common forms of data corruption) in lzip files, and provides data recovery capabilities, including error-checked merging of damaged copies of a file.
- The lzip format is as simple as possible (but not simpler). The lzip manual provides the source code of a simple decompressor along with a detailed explanation of how it works, so that with the only help of the lzip manual it would be possible for a digital archaeologist to extract the data from a lzip file long after quantum computers eventually render LZMA obsolete.
- Additionally the lzip reference implementation is copylefted, which guarantees that it will remain free forever.
The suffix .lz is used for files compressed with lzip.

See https://lists.dyne.org/lurker/message/20181020.205455.fbab5607.en.html for negative claims about Lzip.

A very lightweight representation of the venerable Apollo DSKY. Uses a Touch LCD to bypass all the hardware complexity.

Running emacs on a remote machine via a web interface.

Just what it says. Can use Dropbox, Google Drive or WebDAV as back-end storage.

As of 2022-06-01, it offers sign-in with GitLab, WebDav, DropBox and GoogleDrive on https://organice.200ok.ch/sign_in, or once signed in on https://organice.200ok.ch/files
Perhaps I shall try the GitLab option before WebDav via NextCloud?
The link bin/compile\and\upload.sh on https://organice.200ok.ch/documentation.html#org48615b6 is not formatted correctly: the URL has underscores which are shown as \subscripts.

I run into similar incorrectly encoded characters from time to time, so this might be useful next time.
