Why? Well: The IndexedDB API is callback-based. With JavaScript being single-threaded, a blocking API would mean fully blocking the page, render and basic user interaction included, while the request is being processed. Although this is apparently good-enough for JSON.parse(), the W3C decided to make the IndexedDB API non-blocking. The first drafts for IndexedDB are from … Continue reading IndexedDB is Weird → The post IndexedDB is Weird appeared first on Quentin Santos.
tl;dr: don’t call last() on a DoubleEndedIterator How do you efficiently get the last part of a space-separated string in Rust? It will be obvious to some, but the obvious answer of s.split(' ').last() is wrong. The mistake is easy to make; I encountered it in a recent MR I reviewed, and I realized I … Continue reading Rust Gotcha: last() on DoubleEndedIterator → The post Rust Gotcha: last() on DoubleEndedIterator appeared first on Quentin Santos.
This article will quickly explain the Rust types [T; N], &[T; N], &[T], Vec<T>, &Vec<T> with C code, and what the str, &str, String, OsString and CString add. Arrays and Slices Rust C [T; N] (array)Example: [i32; 100]Allocated on the stack T[N]Example: int[100]Allocated on the stack &[T; N] (array reference)Example: &[i32; 100]N is tracked at … Continue reading Rust Strings for C Programmers → The post Rust Strings for C Programmers appeared first on Quentin Santos.
Although I am now mostly comfortable with Rust, some concepts still elude me. One of them is the exact meaning of Unpin. The documentation says: The documentation of Unpin says: Types that do not require any pinning guarantees. Where pinning is described as: From this, you could naturally deduce that Unpin is the trait that … Continue reading You can move !Unpin → The post You can move !Unpin appeared first on Quentin Santos.

A large part of our civilisation rests on the shoulders of one medieval monk: Thomas Aquinas. Amid the turmoil of life, riddled with wickedness and pain, he would insist that our world is good. And all our success is built on this belief. Note: Before we start, let’s get one thing out of the way: Thomas Aquinas is clearly a Christian thinker, a Saint even. Yet he was also a brilliant philosopher. So even if you consider yourself agnostic or an atheist, stay with me, you will still enjoy his ideas. What is good? Thomas’ argument is rooted in Aristotle’s concept of goodness: Something is good if it fulfills its function. Aristotle had illustrated this idea with a knife. A knife is good to the extent that it cuts well. He made a distinction between an actual knife and its ideal function. That actual thing in your drawer is the existence of a knife. And its ideal function is its essence—what it means to be a knife: to cut well. So everything is separated into its existence and its ideal essence. And this is also true for humans: We have an ideal conception of what the essence of a human […] The post Thomas Aquinas — The world is divine! appeared first on Ralph Ammer.

The Ware for March 2025 is shown below. I was just taking this thing apart to see what went wrong, and thought it had some merit as a name that ware. But perhaps more interestingly, I was also experimenting with my cross-polarized imaging setup. This is a technique a friend of mine told me about […]
