"Your" vs. "My" in user interfaces

news.ycombinator.com Adam Silver 2025-09-26 03:05:53

“Your” vs “My” in user interfaces When referring to the user’s stuff, which is better out of these: “My account” or “Your account”? “My orders” or “Your orders”? “My cases” or “Your cases”? It’s a trick question because often you don’t need any prefix and can just use: Account Orders Cases Amazon is a good example of this in action because it’s obvious that it’s your account and your orders: But what if your product contains things that belong to you and to others – for example, a case

Celestia – Real-time 3D visualization of space

news.ycombinator.com Unknown 2025-09-28 08:30:19

Interactive Planetarium Celestia serves as a planetarium – for an observer on any celestial object. You can easily navigate to any world and land on its surface. When used as a planetarium, Celestia shows accurate positions of solar system objects in the sky. You can switch labels and other supporting features on and off with hotkeys, or zoom in and out on an object of interest, for example Jupiter’s system of moons.

RFC9460: SVCB and HTTPS DNS Records

news.ycombinator.com Authors 2025-09-28 04:26:01

In AliasMode, the SVCB record aliases a service to a TargetName. SVCB RRsets SHOULD only have a single RR in AliasMode. If multiple AliasMode RRs are present, clients or recursive resolvers SHOULD pick one at random.¶ The primary purpose of AliasMode is to allow aliasing at the zone apex, where CNAME is not allowed (see, for example, [RFC1912], Section 2.4). In AliasMode, the TargetName will be the name of a domain that resolves to SVCB, AAAA, and/or A records. (See Section 6 for aliasing of SV

Improvements to OCaml code editing: the basics of a refactor engine

Refactoring features have contributed to the popularity of editors like IntelliJ, as well as certain programming languages whose editor support offers interactive mechanisms to manage code — Gleam being an excellent example.

How a mysterious particle could explain the Universe’s missing antimatter

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current theories, matter and its counterpart, antimatter, ought to have been created in equal amounts at the time of the Big Bang. But antimatter is vanishingly rare in the universe. So what happened? Physicists don’t know the answer to that question yet, but many think the solution must involve some subtle dif

Implicit parameters are always integers, and they must appear first before any other parameters in the function type signature. The first argument can then just be omitted when calling the function, like so: Functions may also have implicit parameters, e.g. we can implement a zero extension function that implicitly picks up its result length from the calling context as follows: Sail will also ensure that the output of our function has precisely the length bits('n * 'm) for all possible inputs
