Aletheia: In short, Aletheia is software for getting science published and into the hands of everyone, for free. It's a decentralised and distributed database used as a publishing platform for scientific research. So, Aletheia is software. But software without people is nothing. To comprehensively answer the question what is Aletheia, Aletheia is software surrounded by a community of people who want to change the world through open access to scientific knowledge. For a more in depth explanation, Aletheia is an Ethereum Blockchain application utilising IPFS for decentralised storage that anyone can upload documents to, download documents from, that also handles the academic peer review process. The application runs on individual PCs, all forming part of the IPFS database. This gives us an open source platform that cannot be bought out by the large publishers (and any derivitive works must also be open source) that should also be hard to take down due to the database being spread across the globe in multiple legal jurisdictions. Aletheia is designed to be a resilient platform run transparently by the community, not some black box corporation or editorial board, meaning all users can see the decisions Aletheia is making and have a stake in that decision making process if they so desire. By this nature, Aletheia is decentralised, it has no key person risk. Should the core group who invented Aletheia dissapear Aletheia won't cease to exist, it will continue to be run by the community. The community moderates content through various mechanisms (peer review, reputation scores etc.,) to ensure quality of content.

DiaSCE: DiaSCE is a C/C++ code editor for GNOME. It pretends to be a complement to Glade, so it doesn't include an environment for GUI development. It has neither a debugger or other kind of tool to help debugging. The idea is for it to be a light code editor that doesn't need too many resources, and makes use of external tools (gcc, glade, ddd, etc.) for some tasks. This project was formerly known as 'david.'

Diakonos: Diakonos is a customizable, usable, console-based text editor. It features arbitrary language scripting, bookmarking, regular expression searching, parsed ("smart") indentation, macro recording and playback, a multi-element clipboard, multi-level undo, a customizable status line, completely customizable keyboard mapping, and customizable syntax highlighting.

Docassemble: docassemble is a system for guided interviews and document assembly. It provides a web application that conducts interviews with users. After each interview, docassemble generates documents in various formats based on user input and preconfigured templates. Though the name emphasizes the document assembly feature, docassemble interviews do not need to assemble a document; they might submit an application, direct the user to other resources on the internet, store user input, interact with APIs, or simply provide the user with information. docassemble was created by a lawyer/computer programmer for purposes of automating the practice of law, but it is a general-purpose platform that can find applications in a variety of fields.

Drishti: Drishti stands for vision or insight in Sanskrit, an Indian language. Drishti has been developed keeping in mind the end-use : visualizing tomography data, electron-microscopy data, etc. Understanding the data set is important and conveying that understanding to the research community or a lay person is equally important. Drishti is aiming for both. The central idea about Drishti is that the scientists should be able to use it for exploring volumetric datasets as well as use it in presentations.

Dungeon-mode: Dungeon-mode is a game engine and REPL for creating and playing multi-user dungeons written primarily in emacs lisp. While playing a game created with dungeon-mode doesn’t necessarily require Emacs authoring game environments (e.g. worlds) does, as do assigning special powers, resolving Ghod calls, Sage encounters, and Ubic -if enabled- or any other or custom events with a dm-intractable property set to a non-nil value. Dungeon Masters may specify delegation rosters to support cooperative oversight and enable teams to direct the play experience.

Ecasound: Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms.

Emaigos: Emaigos is a free multi-platform software useful to import Google contacts and calendars in Emacs. Contacts are stored in a Big Brother Database (BBDB) file, which makes them usable with many Emacs email packages, like Gnus. Google calendars are stored as a single Org mode file, so that the events may be viewed as a structured document and possibly shown within an Agenda view. So with Emaigos it's possible to use Google as contacts and calendars manager, while having at the same time all data available within Emacs. The original Google contacts and calendars are not modified in any way by Emaigos. The name "Emaigos" is an acronym for "EMAcs Importer for GOogle Stuff".

EncNotex: EncNotex is a free multiplatform software, which runs natively on GNU/Linux, Windows and macOS, that is useful to write and to manage a file of strongly encrypted textual notes and tasks. It’s aim is to grant the user an highly secure tool to manage very confidential data. For this reason EncNotex uses the AES 256 bit encryption, cipher mode CBC and SHA 512; the user cannot save unencrypted data on the disk, but only copy it in the clipboard; the required password to encrypt a file is necessarily 10 characters long or more, chosen at least from three of these four groups: small and upper case letters, numbers and other characters (asterisk, brackets, etc.); optionally, the password used to save a file could be forgotten by the software and typed again by the user each time a file is to be saved, so that the same password does not remain in the computer’s memory while the software is being used. A file of EncNotex is a textual encrypted file containing many notes (no database is used). To grant a perfect compatibility of data among the different platforms and to be very fast even with big amount of data, EncNotex has a very simple structure of notes. They cannot have pictures inside nor attachments, but their text can be formatted in bold, italic and underline. Every note has a title, a list of tags (keywords) separated by comma and space, a date and a free-length text, and can be printed. The title and the date of every note is shown in a read only grid on the left of the interface of the software, and a note can be shown selecting its title in this grid. Furthermore, in the same grid the title of a note can be indented or deindented, to make it a subnote of the previous one, or moved up and down, along with its possible subnotes. At the left of the text of the notes there is an outlook of its titles, which can be used to reach easily one of them, and of the possible tasks along with their deadline. The tasks of all the notes of a file can be summarized in a list, sorted, filtered and copied in the clipboard to be pasted in a spreadsheet, or saved in csv or ics format. It's possible to search for a note within the titles, the tags, the dates and the texts. A note or all the notes of a file can be copied in the clipboard in HTML format and then pasted in a word processor maintaining the possible HTML tags. Finally, two independent backup files are automatically created when a file is loaded and when it's saved.

All programs are wired up together automatically providing distributed communication, either through text, images, or games. The source code to all applications is available immediately to instantly clone and modify.

Flac-jacket: 'flac-jacket' uses raw audio files (raw files are created from data streams) as the source. Based on the filename format, it first creates lossless audio files, using FLAC, and optionally removes the source files if conversion was successful. It then creates a new html page with links to all new and existing .flac files. The html page is regenerated each run, so the listing is somewhat dynamic: you needn't edit the html page just because you removed or renamed a FLAC audio file or altered an artist directory.

Flowblade: Flowblade Movie Editor is designed to provide a fast, precise and as-simple-as-possible editing experience. Flowblade employs film style editing paradigm in which clips are usually automatically placed tightly after the previous clip - or between two existing clips - when they are inserted on the timeline. Edits are fine-tuned by trimming in and out points of clips, or by cutting and deleting parts of clips. Film style editing is faster for creating programs with mostly straight cuts and audio splits, but may be slower when programs contain complex composites unless correct work flow is followed.

FocusWriter: Focuswriter is a fullscreen writing program designed to be distraction free. You can customize your environment by changing the font, colors, and background image to add ambiance. FocusWriter features an on-the-fly updating wordcount, optional auto-save, optional daily goals, and toolbars that hide away to allow you to focus more clearly.

MyNotex

Notes are gathered under different subjects and are made by a title, a date, a tags (keywords) list and a free-length text. This may be formatted: it is possible to change the font name, size and color of a selected text and of its background, and also to set bold, italic, underline and strike-through; the text may have pictures within it and hashtags. The software can manage paragraph alignment, bullets, numbered and alphabetic lists with automatic indentation. Each note may have any number of attachments (files of every kind), and has also a spreadsheet-like grid to manage a list of activities which is quite similar to the one used in many software of project management. A single file of MyNotex contains various notes filed in different subjects. Some features of the software:

a spreadsheet-like grid available for each note, in which it is possible to create and manage list of activities and sub-activities with state, dates, resources and cost specifications;
possibility to encrypt and decrypt a file of MyNotex, or any other file, with GNU Privacy Guard (GPG), if available in the system in use;
various attachments (files of every kind) for each note, zipped and stored in a directory with the same name and path of the MyNotex file in use and automatically managed by the software; the number of attachments is limited only by the available disk space;
encryption of the text of the selected notes with AES algorithm;
search for subjects, notes (also in the text), attachments, dates and tags (keywords);
search for more than one tag at a time (in OR condition) and for a range of dates;
importation and exportation of single subjects with the related notes and attachments from and to another file of MyNotex;
direct importation of an OpenOffice.org Writer or LibreOffice Writer file;
importation from Tomboy and Gnote notes;
export data in HTML format, which can be easily opened with a word processor like OpenOffice.org Writer or LibreOffice Writer;
possibility to link a note to another note;
possibility to insert images in the text of the notes, stored in the directory of attachments;
possibility to set the line space and paragraph space of the text of the notes;
alarm clock, to be alerted at a specified time;
zoom of the text with Ctrl + mouse wheel, or Ctrl + +/-;
copy selected text of a note in Latex format.

Finally it is possible to synchronize two different files of MyNotex so that the new, the changed and the deleted subjects, notes and attachments in each one of them are mirrored in the other; at the end of the process, the two files and attachments directories are identical. This feature allows to modify two or more files of MyNotex offline and then connect to the LAN or the Internet and synchronize them, also through a cloud services like Dropbox or Ubuntu One.

OneModel: Today: You can take notes with it. Rearrange them easily, up and down in a list, or up/down in the hierarchy. Link them to each other. Navigate across links with simple keypresses. Make deeply nested lists. Link lists to lists. Compose long paragraphs and attach them. Or do more complicated things if desired, by creating relationship types and using those. Import txt or export txt or html. It's better than the alternatives for some people, because the navigation takes fewer keystrokes, you don't have to read a manual (it's all on the screen, or so I like to think), you can have the same thing in as many places as you want, it is Free (some alternatives are, others are not), and it has immense future potential for becoming a better-structured, much more powerful and flexible wikipedia-like tool, if we work together. Vision: The idea is to have the most efficient personal knowledge organizer (now available in a usable text-based interface), then support mobile access, easy internal automation, and effective sharing and collaboration. Then, to combine efforts and learn as we go until we integrate humankind's knowledge over time. The key differentiators are that it is to be Free, and based on an object model (easily created on the fly as a side-effect of using the system), rather than on massive amounts of words. The knowledge is the same, even if the words can change. One can think of that as "using building blocks of knowledge, starting at an atomic level (i.e. numbers, relationships...), free and efficient." Or, taking the best experiences of online organizer tools and wikis, but more structured, efficient, Free, open, and collaborative; and allowing full individual or organizational control.

QPDF: QPDF is capable of creating linearized (also known as web-optimized) files and encrypted files. It is also capable of converting PDF files with object streams (also known as compressed objects) to files with no compressed objects or to generate object streams from files that don't have them (or even those that already do). QPDF also supports a special mode designed to allow you to edit the content of PDF files in a text editor. For more details, please see the documentation links below. QPDF includes support for merging and splitting PDFs through the ability to copy objects from one PDF file into another and to manipulate the list of pages in a PDF file. The QPDF library also makes it possible for you to create PDF files from scratch. In this mode, you are responsible for supplying all the contents of the file, while the QPDF library takes care off all the syntactical representation of the objects, creation of cross references tables and, if you use them, object streams, encryption, linearization, and other syntactic details. QPDF is not a PDF content creation library, a PDF viewer, or a program capable of converting PDF into other formats. In particular, QPDF knows nothing about the semantics of PDF content streams. If you are looking for something that can do that, you should look elsewhere. However, once you have a valid PDF file, QPDF can be used to transform that file in ways perhaps your original PDF creation can't handle. For example, programs generate simple PDF files but can't password-protect them, web-optimize them, or perform other transformations of that type.
