• The First Stable Release of a Rust-Rewrite Sudo Implementation

  Are those more important than, say: - Proven with Coq, a formal proof management system: https://coq.inria.fr/ See in the real world: https://aws.amazon.com/security/provable-security/ And check out Computer-Aided Verification (CAV). - Source: Hacker News / over 2 years ago

• In Which I Claim Rich Hickey Is Wrong

  Dafny and Whiley are two examples with explicit verification support. Idris and other dependently typed languages should all be rich enough to express the required predicate but might not necessarily be able to accept a reasonable implementation as proof. Isabelle, Lean, Coq, and other theorem provers definitely can express the capability but aren't going to churn out much in the way of executable programs;... - Source: Hacker News / almost 3 years ago

• If given a list of properties/definitions and relationship between them, could a machine come up with (mostly senseless, but) true implications?

  Still, there are many useful tools based on these ideas, used by programmers and mathematicians alike. What you describe sounds rather like Datalog (e.g. Soufflé Datalog), where you supply some rules and an initial fact, and the system repeatedly expands out the set of facts until nothing new can be derived. (This has to be finite, if you want to get anywhere.) In Prolog (e.g. SWI Prolog) you also supply a set of... Source: about 3 years ago

• Mark Petruska has requested 250000 Algos for the development of a Coq-avm library for AVM version 8

• Basic SAT model of x86 instructions using Z3, autogenerated from Intel docs

  This type of thing can help you formally verify code. So, if your proof is correct, and your description of the (language/CPU) is correct, you can prove the code does what you think it does. Formal proof systems are still growing up, though, and they are still pretty hard to use. See Coq for an introduction: https://coq.inria.fr/. - Source: Hacker News / about 3 years ago

• PHP's Biggest Problem

  The PHP website is indeed one of the worst parts of the whole ecosystem. Just look at the landingpage (https://php.net) and compare it with those of other languages. There's not a single piece of PHP code on the page. No "what is PHP", no "why should I use it", and no "that's why PHP is great". It's just a news page showing the latest releases, and a small section for downloading PHP. And speaking of the website:... - Source: Hacker News / 2 months ago

• Self Hostable Multi-Location Uptime Monitoring

  My initial idea was to leverage the main application’s queue worker by deploying a queue worker remotely and setting up a secure connection between them using something like Wireguard. Vigilant is written in PHP using the Laravel framework, for queuing it uses Laravel Horizon. This is a queuing system built on top of Redis. All monitoring tasks in Vigilant are executed on this queue, it allows for multiple queues... - Source: dev.to / 8 months ago

• The Lost Art of Reading Documentation

  I remember being 15 (18 years ago 🥲) and learning PHP. Stack Overflow wasn’t as big yet, and finding answers often meant digging through forums filled with half-baked solutions, each dependent on specific hosting configurations. There was no universal standard, some hosts supported certain php.ini settings while others didn’t. The only reliable resource? The official PHP documentation: php.net. - Source: dev.to / over 1 year ago

• Using named arguments in php8 and up

  That's the first I've heard of it, and I like it! I can't tell you the number of trips to php.net to look at argument order for a function. Is it haystack/needle, or needle/haystack? Of course it could turn into the same thing w/ argument names (is it whole_name or full_name?), but I'm going to use it. Source: about 3 years ago

• How to display results from multiple SQL queries in the same table cell?

  Prepare to spend a fair bit of time reading and going back to phptherightway.com and php.net. I've also found this Tutorial from Envato Tuts+ to be quite good. Source: about 3 years ago
