Maybe this http://tiddlywiki.com/

I use tiddlywiki and I am very happy with it. Too bad dev has been discontinued though,

Discontinued? It has over 100 contributors, and the last stable release was two months ago ... I think it is very much alive: https://github.com/Jermolene/TiddlyWiki5

That's great news! I didn't know it was still actively developed. I played with it... criminy how many years ago did it first start? I liked it then but it was brittle and slow.

It looks great now, functionally and speed-wise. Obviously computers themselves changed a lot in that time to give the speed improvement.

Looking forward to playing with it again now.

This might be close to what you're looking for: http://www.trunknotes.com

It's a wiki that runs off your iPhone. You can use it on your desktop or other computers via a built-in server. You can script it and create macros via Lua.

For your notebook, make a pen/pencil holder out of electrical tape or duct tape. Or buy one if you can't be bothered:

> and keeps your information synchronized between them.

Is the implication that the browser-based wiki is not storing your data on a central server (e.g. always synced) but should provide some other way to sync? (I'm working on something in this ballpark, genuine curiosity).

I'm a proponent of "offline first". So my recommendation for any apps - like a wiki - should save to localStorage first, then behind-the-scenes sync up to one's own personal server (alternatively a host provider that a customer can pay to manage on behalf of them). Then if one should ever install a new/another instance of the wiki on another device, the app should download all the latest from the personal server. Anyone who builds such a thing would instantly become a hero! ;-)

Yes. Something like:

1. Download and install a wiki application to each computer we use, including pocket ones.

2. Editing the wiki on each computer saves to offline local storage.

3. An option to define a personal central server is available in settings. If this is activated and our login credentials are set each app auto-syncs with server automatically whenever wifi is available or a 'sync' button on the top-right of the viewport is activated. Furthermore, an open source example implementation of this server, perhaps powered by sandstorm.io and Google App Engine, is made available.

In other words, an open source app on each owned computing device editable using WikiWords that automatically create /w/WikiWords pages, synchronized across devices. Bonus points for eventual options to publish a version of the wiki and make it editable by anyone, perhaps using [Git](https://github.com/gollum/gollum/).

I got this idea from the Manage Your Knowledge section of Andy Hunt's [Pragmatic Thinking and Learning](https://pragprog.com/book/ahptl/pragmatic-thinking-and-learn...), that I warmly recommend to anyone interested in learning.

I created EncryptedGist [1][2] to cover part of this use case. It gets me Vim backed by GitHub Gists on any machine I happen to be working on. Adding localStorage would be easy [3], but undesirable for my main purpose - I do not want any of my personal information remaining on the machine.

Edit: And just in case it wasn't obvious, I prefer to maintain my todo list/logs/notes/projects/bookmarks in a single plaintext file. Grows about 30k lines/year. Vim search/grep and some basic structuring/naming conventions go a long way.

Top of the file is my todo list with priority order of top 3 tasks. Next is a 'Waiting For' list. Last is a 'Projects' list for longer term, high-level categories. This fits on a single screen. Completed tasks, meeting notes, logs, bookmarks, etc., go below in chronological order and are all associated with a date. This system has worked well for the last decade or so with minor changes.

Just having offline mode would be quite often enough.

Simplenote is great. Instead of Notational Velocity I use something called Just Notes, but is discontinued. I've been meaning to make my own using Electron and Draft.js with a few things that annoy me with it / would like to be improved.
