A bit of a tangent, but it's interesting how many languages come from Nordic countries: - Simula - Norway - C++ - Stroustrup is Danish - TypeScript / C# - Hjelsberg is Danish - PHP - Lerdorf is Danish - the v8 team including Lars

Yes totally, I keep seeing people mention these arena / flattened tree and graph structures, without mentioning memory safety. And also weird claims that arenas solve memory safety problems in C, when it's equally likely (dependi

Just to elaborate on what bugged me about this essay -- probably the most important part for many domains is a single sentence, the last one in this paragraph: Most of us can benefit from collaborating with colleagues, but some projects re

It is a bit weirdly generalized I kept trying to read between the lines for the domain PG is known for and writes most frequently about — startups But a lot of the writing seems to apply to achievements in math, science, art, and literature

Yeah it seems like most of the responses are against this proposal For casual readers, it's a proposal, not something decided

On an Android phone, Linux is effectively an application runtime. This is a good way of putting it, and it’s sad Our OS is no longer open source -- they built the real one underneath

I'd define an arena as the pattern where the arena itself owns N objects. So you free the arena to free all objects. My first job was at EA working on console games (PS2, GameCube, XBox, no OS or virtual memory on any of them), and wh

Arenas were pervasively used in the 80s, 90s, 2000s, ... and are still widely used Using Malloc and free in the naive way was the exception, not the rule They can be the cause of memory safety problems in some cases, as well as a partial so

Yeah I agree, seems like most of the comments here are talking about slightly different things, with different tradeoffs Including memory safety

Counterpoint: I read many of these "handles" articles several years ago, and tried them in my code, and it was something of a mistake. The key problem is that they punt on MEMORY SAFETY An arena assumes trivial ownership -- every

Two good examples of the flip are the Ferry Building in SF and Chelsea Market in Manhattan. Those used to be big industrial / shipping / cargo buildings but now sell upscale food :) It's kind of funny how you see the same ec

Yeah it's way nicer to live up the hill a little, basically anywhere up a hill. The low-lying areas have "gravity" that attract bad things. I made the same mistake moving to SF in 2002, until 2004. It was bad then -- and su

FWIW I worked in software for 14 years, and never used Slack or Discord, so I wouldn't be so quick to generalize "Everybody else is doing it" is a weak argument "Everyone else" isn't building a browser from scr

What kind of software do you work on? At what company? I have seen low level parts that are managed well, because employees have skin in the game But I’ve also seen a lot of what this post is talking about

Zulip has a better and faster interface than Discord IMO, and it's published under the Apache 2 license, making it free software: https://github.com/zulip/zulip I've been using it at https://oilshe

YouTube (2005) and Google Maps (2005) still going strong You can criticize both of them, but overall they changed the world in huge ways, mostly for the better On the other hand, Google Search seems like it created incentives that rotted th

Right exactly. The conventional ways of writing it would be \U0001F914 -- must be exactly 8 digits \u{1f914} -- 1 to 6 digits Almost all languages have these now, but JavaScript didn't when JSON was invented. The "J

I would say Wikipedia has been overly aggressive in their fundraising But it hasn't enshittified I would be really happy if Reddit ended up like Wikipedia. You can argue that Wikipedia could make better use of their funds (you can alw

That's kind of what I suspected ... it seems like a self-inflicted problem, a consequence of the VC model and "enshittification" This makes Wikipedia seem prescient. It also has basically all user-contributed content, and us

But I've been curious for the last week -- why isn't Reddit profitable anymore? Did something change about ads since 2015 (likely) ? Did their cloud costs go way up ? (possibly, since the redesign seems extremely slow and resourc

Yes, technically it means "there's more than one derivation" But Python's pgen rejects such grammars as invalid ... The other strategy is just to pick an arbitrary interpretation

Nice article! In this sentence ... open parenthesis character is ambiguous in this context. To get around it they made their grammar more ambiguous and then enforced that the actual grammar was enforced in their tree builder. I'd ch

OK yeah, the 3:bag is easy to see. With netstrings, it's 3:bag, with a comma, which makes it a bit more readable over the wire. The extra level of Racket quoting was confusing me -- #"" and \" -- it would be n
