From a user POV, I think == and === on floats should simply be undefined in any language. It should be a compile time or runtime error. There can be a separate function `float_equals()` with explicit args that does what people want The only

So this is about creating SQL strings with SQL? Not interpolating SQL with ? placeholders in say Python. The article could have made that much more clear. It reminds me of the bash-completion project which is the default on Debian-based di

Yes definitely, which is why I mentioned Cardelli. Previous comment on the same subject: https://news.ycombinator.com/item?id=21832009 A program fragment is safe if it does not cause untrapped errors to occur. Languages

Yeah that's an interesting consideration, but it's more of a systems design issue, outside the scope of what the C or Rust compilers and runtime can do anything about. (Or Python, JavaScript, etc.)

Instead of stack overflow causing a crash, it could silently overflow into heap memory. Do you want that? What I'm saying is that crashes are the thing that PROTECT you from undefined behavior at runtime. --- If a C program crashes, t

by chubot 3y ago
What I also think is weird is that people think seg faults and crashes are "unsafe". In the terms of Cardelli, a stack overflow is a trapped runtime error -- and thus a SAFE behavior of a language runtime. What's not safe is

Well at least the shitty MPAs will run on other people's servers, rather than shitty SPAs running on my phone and iPad FWIW I turned off JavaScript on my iPad a couple years ago ... what a relief! I have nothing against JS, but the sit

This isn't quite true. Python was certainly Guido's passion project, and it started that way. But early in its life, it was funded by the United States government via CNRI (under Bob Kahn). At every job Guido had subsequently, h

Glad to see this covered -- I also had the experience of picking it up the hard way, over many years! My own tips after writing a custom build system for C++ - the order of objects and -l flags to the linker matters! I remember being very

Seems like it could be interesting ... Initial impression is that the animation of Mojo code vs. Python code has a bad UX. Why not just show the code side-by-side instead of animating it and making me click? Another obvious question is how

Yes I know, but Ubuntu seems to be more popular as a desktop What I mean is that people just hack on stuff on their desktop. They install Python NumPy or Rails or whatever. Like gigabytes of dependencies. And then they want to deploy. Is

This looks cool, but what's the dev environment like? I think Ubuntu is a popular base image in Docker because Ubuntu is popular for engineers to use on their desktops Debian usually passes for Ubuntu, since the package names are mostl

Ah very interesting, I had heard of Pants, but I didn't know about Pants 2. Having less BUILD metadata definitely seems like a big win, and I imagine with some effort you can keep the parallelism/caching/distribution too (I&

The linked paper is pretty interesting, and short at 4 pages. In plainer language, I'd say the observation/motivation is that not only do compiling and linking benefit from incrementality/caching/parallelism, but so does

(Oil author here) Thanks for mentioning it -- Oil is intended for exactly that kind of thing, in theory. That is, a clean shell language for gluing together distros, which are inherently heterogeneous and messy. In practice, I think there

That seems pretty clear to me? The web made programmers drastically more productive, and it coincided with a huge increase in both total employment and salaries, not a decrease. For example, I first used Google in summer 2000 at a college

Python 2.7 was released in 2010, and is even more frozen than Perl! It still works, though you would have to archive/vendor dependencies
