No, I didn’t change the title. Blame the submitter :)

https://jmtd.net/

I've been blogging for about 20 years. Exactly what I write about has changed over that time (of course), but in recent times I've been writing about my PhD (applying purely-functional programming to distributed stream processing); cultural stuff I like, books, music, in particular Nintendo Switch games recently; free software stuff, particularly around Linux and Debian (I'm a Debian developer); note-taking and personal productivity; reading and archiving old media (minidiscs, ZIP drives, stacks of DVD-Rs, floppy disks); my fledgling adventures in 3D printing; retrocomputing and restoring my old Commodore Amiga; various classic Doom hacking projects I've worked on; running and maintaining a DIY free software NAS; computing history and preservation…

I wouldn't normally post in a thread like this but a friend put me up to it. Any feedback appreciated.

> but the fact that a two records can't share field names

That is awkward sometimes yes. Record fields are functions, and you can't have two functions with the same name in the same namespace.

You can, however, use namespaces to import two separate modules with conflicting names. It does mean you have to define the two different records in two different modules.

If, you want different records to have common fields because they are conceptually related, you probably want to use type classes.

Much the same sort-of chronology and hosting story for me…

> For my real-name vanity domain, I went with a `.org`, since I didn't want to be a `.com` in personal life, though today I'd prefer `.net`.

I'm curious to pick your brains on that. I've gone the other way: I ended up standardising on a .net but I kinda wish I had the .org instead, my rationale is, .org is a closer match to what my site is: if I squint I can consider it to be an "organisation" of one, but I can't convince myself that it or I'm a network. I originally picked the .net because I thought it scanned better with my choice of domain.

Me too. I have a simple static site/blog with mostly textual content going back to around 1999 and I'm lucky to have a reasonably unique firstname/lastname combo (ish); my blog currently is top on Google and Bing.

> Try googling for John Carmack,

And what should the top match for John Carmack be, in your opinion? Where is his homepage?

FWIW on Bing I got his Wikipedia article first and his twitter accoount second, which seems like sensible results in his case.

Thanks. I didn't know that, but I don't install FB because of some other stuff I heard they did (like monitor the mic). Likewise messenger. I do access FB, but only from within Firefox, which I use soley for that purpose.

I'm trying to determine whether iOS apps could sniff my clipboard, and i haven't proven that they can't; it doesn't seem to be a specific permission that needs to be assigned or can be denied. And thus using 1Password on my iPhone to copy and paste passwords seems to have a bit of a risk to it.

For ultra purity, there's basically only Chocolate Doom (or DOSbox and the original game). For modern features (but losing the Doom "feel"), (G)Zdoom or Doomsday; for stuff in the middle, Doomretro, Crispy Doom, Prboom+, Eternity.

I'd say Crispy Doom (or Doomretro on Windows) are good balances.

Doomretro is lovely, but if you really want a close-to-pure-as-possible experience, look at the (parent) project Chocolate Doom.

The OP's example ( is-positive-integer) has tests, and is only three lines long, and is on major release version 3.X, because despite all that, it had serious problems in versions 1 and 2.

The user interface/experience of PGP/GPG is not great, and that could do with fixing. However if you already understood how to use PGP (and granted that's unlikely for the users Mint targets), then you would not have been caught out by this.

They almost certainly are not moving ATA commands over those ribbons, so SATA wouldn't be much use.

Perhaps the title-writer has been infected by the BBC news editorial policy. They seem to be turning clickbait titles into a fine art, combined with renaming articles so you think it's a new piece on the same story, but turns out you've already read it. (If you read BBC News at all that is: my wife still does, I gave it up years ago and haven't looked back.)

I love many aspects of the BBC but sadly not their news output anymore.

(Sorry I realise this has very little to do with the R&D article.)

If you need 8G of resident memory to have the apps you want running then you need 8G... no shortcuts. That is a pretty high figure, though. Afaik things like disk caches aren't restored during a suspend/resume.
