HN discussionI love this book, even since its first edition. It's very clear even on elementary stuff, e.g. see the section on bindings/variables: https://eloquentjavascript.net/02_program_structure.html#h-l... — avoids the pitfall of thinking of variables as “boxes”. I was trying to find what's new in the 4th edition, and following links from the author's website https://marijnhaverbeke.nl/ found this on Mastodon ( https://mast…

HN discussionCRDTs seem very promising, but we still have a long way to go. The most exciting work in this area is being done by Ink&Switch [0]. They have a number of interesting real-world app prototypes based on CRDTs. - An interesting case where CRDTs failed is Xi-editor, where they tried to use CRDTs as the basis for a plugin system [1,2]. - One of the biggest problems with CRDTs is the overhead needed to keep track of the f…

HN discussionI love Nuclino too. Their editor uses the wonderful ProseMirror ( https://discuss.prosemirror.net/t/nuclino-a-lightweight-real... ) by Marijn Haverbeke ( https://marijnhaverbeke.nl/ ) of CodeMirror and Tern fame.

HN discussion> I don't see how recursive queries are going to help you You construct a graph of objects with very few queries, transform it and write it back; with knowledge of the db-schema this will outperform any ORM-based solution and give much greater flexibility. > As for building queries [...] The problem is that it composes very badly.

HN discussionI'd add that the assumptions that the specialized data structures (gap buffer and piece table) make are easily violated—someone mentioned a search-replace further down—at which point I can imagine their performance degrading unless special measure, i.e. more complexity, are added. So yeah, in my editor (CodeMirror) I'm also using a rope/tree style representation [1], because it's pleasantly general and easy to reaso…

HN discussionAs nacs said but in other words, CodeMirror is syntax colored and directed code editing (emacs), while ProseMirror is wysiwyg text editing (word). CodeMirror was started in early 2007. [1] ProseMirror is newer, announced July 7 2015 [2]. You've probably been using CodeMirror but didn't even realize it -- it's ubiquitous! >CodeMirror is an open-source project shared under an MIT license. It is the editor used in the…

HN discussionMy ProseMirror [1] project is in the same space (including using persistent data model detached from the DOM). It has a richer, tree-shaped document model and collaboration [2], but not quite as much programmerpower behind it since I'm a single OSS dev as opposed to a giant tech company.

HN discussionA lot of the same refactoring is possible in dynamic languages as in static ones. I recommend reading up on Term to see what's possible to do with JavaScript http://marijnhaverbeke.nl/blog/tern.html I use Cursive https://cursive-ide.com/ for working with Clojure, and it can do safe refactoring for symbols by doing static analysis of the source. It can show all usages of a symbol, rename it, do automatic imports, and…
