Possible disadvantages of Replay.io

Resource Intensive
Using Replay.io might require significant system resources, possibly slowing down the development environment.
Learning Curve
Although it is user-friendly, some of the more advanced features might require time to learn and master.
Subscription Cost
Depending on the chosen plan, the subscription cost might be a barrier for smaller teams or individual developers.
Performance Overhead
Recording and replaying sessions could introduce some performance overhead, potentially affecting the user experience during testing.
Limited Offline Capabilities
Replay.io's functionality is heavily reliant on an internet connection, which can be a limitation in offline or low-connectivity environments.
Compatibility Issues
Might face compatibility issues with certain legacy systems or less commonly used browsers, limiting its versatility.

HHVM features and specs

Performance
HHVM uses Just-In-Time (JIT) compilation to convert PHP code into machine code, which can significantly improve execution speed compared to traditional PHP interpreters.
Hack Language Support
HHVM supports the Hack programming language, which offers additional features like static type checking, generics, and asynchronous code execution, allowing developers to write safer and more efficient code.
Scalability
HHVM is designed to handle high-traffic environments, making it suitable for large-scale applications and websites with high concurrency demands.
Open Source
HHVM is open-source software, allowing developers to contribute to its development and benefit from community-driven improvements and support.

Possible disadvantages of HHVM

Compatibility
HHVM is not fully compatible with all PHP extensions and libraries. This can create issues when migrating existing PHP applications to HHVM, requiring additional refactoring.
Resource Intensive
HHVM can consume more memory and CPU resources than traditional PHP interpreters, which might be a concern for applications running on limited hardware.
Linux Focused
HHVM primarily supports Linux-based systems. While there is some support for other operating systems, it may not be as robust, limiting its use in heterogeneous environments.
Evolving Technology
HHVM and the Hack language are continuously evolving, which can lead to breaking changes and the need to keep development teams updated with the latest features and fixes.

Show HN: Time travel debugging AI for more reliable vibe coding
Hi HN, I'm the CEO at https://replay.io. We've been building a time travel debugger for web apps for several years now (previous HN post: https://news.ycombinator.com/item?id=28539247). We recently launched Nut (https://nut.new) as an open source project which uses this tech for building apps through prompting (vibe coding), similar to e.g. https://bolt.new and https://v0.dev. We want Nut to fix bugs effectively... - Source: Hacker News / about 2 months ago
Time Travel Debugging: Beyond Console.log
Tools like replay.io and Firefox's DevTools let you record your application's execution and play it back later. It's like TiVo for your code! - Source: dev.to / 3 months ago
Don't Look Down on Print Debugging
Have you ever been able to try https://replay.io time travel debugging as an alternative to conventional logging? Last time I tried it you were able to add logging statements "after the fact" (i.e. After reproducing the bug) and see what they would have printed. I believe they also have the ability to act like a conventional debugger. I think they're changing some aspects of their business model but the core... - Source: Hacker News / 5 months ago
A (Mostly) Complete Guide to React Rendering Behavior
Not at this time. I'm pretty full up at this point with day job ( https://replay.io ), conferences, and personal life stuff. My current ongoing Redux maintenance task is trying to revamp our "Redux Essentials" tutorial to be TS-first. Making slower progress on that than I'd wanted, but hopefully can get that wrapped up in the not _too_ distant future. Beyond that, we've got a ton of open RTK Query feature requests... - Source: Hacker News / 12 months ago
Is Something Bugging You?
Exactly - that's what we've already built for web development at https://replay.io :) I did a "Learn with Jason" show discussion that covered the concepts of Replay, how to use it, and how it works: - https://www.learnwithjason.dev/travel-through-time-to-debug-javascript Not only is the debugger itself time-traveling, but those time-travel capabilities are exposed by our backend API: -... - Source: Hacker News / about 1 year ago

THT v0.8.1 – A modern re-design of PHP
$hayStack.contains('needle') This looks more or less like a new language ? It must be amazing amount of time and energy to rewrite PHP in to this. I don't see the benefits. I understand the Facebook's HHVM had some. (https://hhvm.com/) Or Swoole (https://openswoole.com/) has it. But I'm not clear of THT (also typical apple vs oranges benchamrkTM included). 2cents. - Source: Hacker News / 6 months ago

Nvidia is now worth more than Meta
Meta has created/maintains ReactJS, Zstandard, IO_Uring, PyTorch, HHVM, is a member of Rust foundation, and that's only the things I know about. They've literally made the Web and Linux better and faster. Source: about 3 years ago

A brief history of Rust at Facebook
If you ever need to work with PHP, use PHP/Hack developed by Facebook: https://hacklang.org/ It's a compiled language built partially in Rust, being rewritten entirely in Rust, JIT compiled using HHVM: https://hhvm.com/ I don't believe it's compatible with existing PHP codebases, but you could probably convert one over in a straightforward way, catching safety issues while you did it.
