What Hacker News says?
"Also, I wouldn’t have hired the guy who doesn’t use semicolons in his JavaScript, either." This seems very similar to the c++ issue with single statement ifs. https://flaviocopes.com/javascript-automatic-semicolon-inser...

HN discussionNot too serious but I want to stop using a language still forcing me to type semi colons. CSS -> Stylus. I don't even have to type brackets and colons and not just semi colons. JS -> JS (TS). Some people may not be aware but you can fully write JS by omitting semi colons. (Except on a few occasions* but I can write a project without one just fine and decent editor will warn you when you're supposed to have one, like…

HN discussionWriting one technical blog [1] post per day. I started in January. Back then I had ~400 people on the blog on a good day. It's paying off in terms of traffic, as last week I got over 2k visits from Google alone, but more importantly I learned a ton in the past few months, because of the continuous process of learning / building something / testing / writing / revising / incorporating feedback / repeat the next day.…

HN discussionMaybe try fish? Tab completion will suggest subcommands, and if you type - or -- and hit tab, it will suggest the available options with help text generated from man pages (example: https://flaviocopes.com/images/fish-shell/autocomplete.png ). Doesn't really help with positional arguments but it's definitely enhanced the discoverability of many tools for me.

HN discussionHere a few guides that I used in the past that helps me to understand and how to set up for Calibre-Web to work with Docker. I have a guide for the Docker with local filesystem that helps me to make it work[1],[2]. I remember that Docker is particular with file path and you have to use the Docker file path convention, they uses forward slashes instead backslashes like Windows.

HN discussionNot sure about the Jupyter-specific issues but macOS comes with Python 2 installed, so you have to install Python separately and use the `python3` binary, or alias `python` to the `python3` binary. Then remember to run pip using `python3 -m pip <command>` and use virtual environments (venv) I stumbled on this a couple weeks ago and documented the process here https://flaviocopes.com/python-installation-macos/ I foun…

HN discussionThe difference, at least for Vue single file template components is that it's 3 separate areas in one file: - <template /> (Templated HTML) - <script /> (JS OR Typescript) - <style /> (CSS OR SASS/etc) Whereas in old PHP files you could mix it in anywhere and the files were a big mess. Including inline SQL into your view templates which is hardly a good separation of concerns. While a Vue component can be separated…

HN discussionAs far as I know, a (C-like) language must either have: - A statement separator (semicolons) - Significant whitespace Otherwise parsing the language is very likely ambiguous, e.g JavaScript [1] [2].

HN discussionAh my bad, I think that's the wrong link describing the old process. I remember a recent talk by Axel (author of that post) describing the new process where features are accepted as soon as they are done (i.e. stage 4). But I can't find any articles by him to back this up, so maybe my memory is failing me ;-) Update: ok, as soon as a proposal reaches stage 4 it's considered finalized and part of the standard.
