I have question. Do you think that this could be used as a brick to build an alternative web browser?

#192Wow. The core is a single 1.5MB file that's very readable, it supports nearly all of the latest standard, and Bellard even added his own extensions on top of that. It has compile-time options for either a NaN-boxing or traditional tagged union object representation, so he didn't just go for a single minimal implementation (unlike e.g. OTCC) but even had the time and energy to explore a bit. I like the fact that it's…

JS is the new PHP. It's really popular (i.e. lots of n00bs) and not at all elegant, so the programmer elite regard it with derision.
I also notice people often conflate the problems of overzealous browser-based scripting with JavaScript the programming language. This is pretty understandable since JavaScript has been the only browser scripting option for 2 decades, but those problems would exist no matter what options were available for browser scripting. It's a safe bet to assume that the problems would actually be much worse if JavaScript wasn't the only browser scripting language available since that would mean browser-based scripting would be more accessible to more programmers.
In another 6-8 years when WASM targeting alternatives become more mature we will see a new explosion of browser scripting.

Can't speak to 1, but I kind of feel like TJ Holowaychuk in the Node.js community started getting close to Fabrice's level (until he left Node). Express, Stylus, Koa, Formidable, etc...
TJ has created a large number of popular software packages, but I don't consider the depth of the software to be close in complexity of the type of software that Fabrice is capable of - basically anything he puts his mind to. bellard.org - has the most impressive portfolio of software created from a single developer I've ever seen. It's more astonishing how varied each of his accomplishments are - covering some of th…
Yeah, it's the breadth that gets me. There are several very impressive expert programmers in their area, but Fabrice seems to be able to step into any subfield he finds interesting, work on it for a couple years, then leave something behind that others are willing to spend years of their lives maintaining and extending. I could see QuickJS quietly running on a Mars rover 10 years from now. Not because JS. Because Fabrice. Always bet on Bellard.

The comment you are replying to gives the reason of disliking the abuse, to weaken the point on the dislike of Javascript, not to fortify it.

And unless there's another software engineer named Daniel J. Bernstein out there, he also authored RFC 1143 documenting the Q Method of TELNET Option Negotiation [1], which prevents negotiation loops and nails down (in the shape of a state machine) exactly what behavior is good and proper for a Telnet peer. I referenced this document a lot when writing my own Telnet stack. [1] https://datatracker.ietf.org/doc/rfc1143…
>…when writing my own Telnet stack. There’s probably an interesting story hidden in there.
That probably depends more on the listener than on the story!
I played MUDs for several years, at the same time that I was learning the ins and outs of programming. I developed some plugins for a popular third-party client called MUSHclient. The game I played also had a somewhat proprietary first-party client, and they used a spare Telnet option (one left unassigned by IANA [1]) to pass data from the server to the client to drive some extra graphical widgets on their client. I got involved in developing plugins that made use of that data, which led me to learning how to negotiate that option with the server and get the data I wanted.
I eventually started developing my own MUD client, which is where the Telnet stack came in. Now, writing a Telnet stack is just something I do when I learn a new language. It's just large enough of a project to exercise some architectural and API-level concerns.
[1] If you're curious, all of the formally allocated Telnet options are documented here: https://www.iana.org/assignments/telnet-options/telnet-optio...

I'll give you Lua, but can this compete with LuaJIT?

I have two question in my mind. 1. Are there anyone on HN knows him in real life? 2. Does anyone have other people in their mind who is in the same league as this man? Mike Pall's LuaJIT sort of make him at this level but that is only one thing. Fabrice create things that everyone are using it one way or another, and if it wasn't HEVC patents mess we would have his bpg [1] replacing jpeg. [1] https://bellard.org/bpg/
