I arrived in China 2001.
I experienced the harshest and largest lockdown in all of history: Wuhan, January 23rd, 2020. A real lockdown, not the cosplay bullshit you experienced outside of China. (Yes, this is me saying you’ve never fucking set foot in the country.)
The rest you’re just flat-out lying about. Sorry, Sparky. Did pet killings happen? Yes. They were not the mass shit that the press you’re so obviously reciting acts like they were. Did some doors get welded? Yes. But nowhere near you and, again, nowhere near in the masses the press you’re basing your lies on made it seem like. The local salaries are garbage iff you’re a fuckwit sitting in the west applying western prices to Chinese salaries. (Which, naturally, you are, good little fuckwit liar that you are.) And you’ve changed your tune from 14 hours to 12 hours really fucking quickly there, Sparky, not to mention using the proper slang only after I gave it to you.
So yeah, you’re just a west-dwelling fuckwit lying about being here. Go toddle off in your China Watcher corners and play with the rest of the intellectual children you belong with. There’s a good boy.

Not trolling. Just:
- showing how clever optimizers can get these days
- introducing a cool web site
- highlighting the importance of occasionally peeking under the hood to spot gross inefficiencies
I mean it could hurt:

4·9 months agoI read it ages ago when it first came out in paperback (which means, sadly,without the music).
I really enjoyed it, but it was very slow reading.
I think that entire documentary could be summarized as “Drugs. Lots of drugs. Lots of drugs in lots of varieties.”
Babylon 5 is a weird show for me. When it was first running, I religiously watched it. If I couldn’t watch it live, I got upset and went around my circle of friends to see who’d recorded it so I could watch it as quickly as possible. Up to Season 4 I was gripped. (Season 5 was “meh” because of production shenanigans.)
Years later I watched them on DVD and … the magic was gone. Watching one episode after another, without separating them by a week, just took the shine off of it. I didn’t even finish watching the episodes on DVD; I think I made it to mid season 3 (and the amount I watched slid down and down up to that) before not bothering to continue. I eventually gave them all to a friend of mine and never watched the show again.
I can’t think of a single show I’ve ever watched that had that weird impact on me: first loved, second bored. Usually shows I loved I keep loving, shows I was bored by remained boring, and very occasionally a show I thought was boring the first time got more interesting on second viewing. But B5? It’s the only one that goes this way.
1·11 months agoI have always understood that C generally compiles almost directly to assembly with little to no abstraction overhead, and it would not require platform-specific ASM code.
You have always understood incorrectly then. I’d recommend a trip over to Godbolt and take a look at the assembler output from C code. Play around with compiler options and see the (often MASSIVE!) changes. That alone should tell you that it doesn’t compile “almost directly to assembly”.
But then note something different. Count the different instructions used by the C compiler. Then look at the number of instructions available in an average CISC processor. Huge swaths of the instruction set, especially the more esoteric, but performance-oriented instructions for very specific use cases, are typically not touched by the compiler.
In the very, very, very ancient days of C the C compiler compiled almost directly to assembly. Specifically PDP-11 assembly. And any processor that was similar to the PDP-11 had similar mappings available. This hasn’t been the case, however, likely longer than you’ve been alive.
Now that one does look interesting. I’ll have to wait for it to show up on my usual sites though: it’s not the kind of movie that will wind up in theatres here.
Except that the age of the mid-budget, self-contained movie is dead. Indies are getting squeezed by this Big Tent nonsense BADLY.
Easy for me to say “no”, though, which is what I did ages ago. Maybe someday the public will get as bored as I got with seeing the same thing over and over again and will kill this franchise nonsense.
I’m tired of all these big tent “franchises” entirely.
Hey, filmmakers, authors, television producers, etc.: MAKE SOMETHING NEW FFS!
I think you’re missing a few key points:
-
It’s a COMEDIC series, not a serious drama. It’s Adams taking potshots at things that struck him as funny or upset him. Like the whole “shoe event horizon” thing was an eloquent rant about how he couldn’t find shoes that fit one day. (No, really!) The fact that it blew up into this massive thing was an accident, not a design, and he didn’t set out to write a Serious SF Series™.
-
The “Britishness” of the relationships is part of that comedy. He’s making fun of Brits’ “reserve”.
-
The Fenchurch thing never really fit into the vibe, and given the series’ entire schtick of random things occurring out of nowhere and then vanishing into nowhere (like the guy whose every incarnation was killed by Arthur Dent), it’s on-point for her to just vanish into nothingness. (And as for his reaction, consult point 2.)
TL;DR Summary
This is a comedic series best viewed as a collection of incoherent, inconsistent vignettes with an underlying theme (kind of like the more serious The Martian Chronicles of Ray Bradbury), not as a serious space drama spread out over books.

32·1 year agoOh, sorry, did any of your pearls fall? Thanks for your precious “engagement”.
I guess it’s scary for some people to participate in even a conversation about something new with an open mind without being condescending.
Irony, thy name is … well, just check the user name. It’s all you need.
Play is not accessible to me; that’s not an avenue I can travel down. I basically have to pirate as a try-before-I-buy thing.
And I don’t buy e-books for reading. (I’ll by them for reference works, game rules, etc. but not reading books.) I buy books. It’s a quirk of mine.
The author, w/o explicitly mentioning it anywhere, is explicitly talking about distributed systems where you’ve got plenty of resources, stable network connectivity and a log/trace ingestion solution (like Sumo or Datadog) alongside your setup.
That is the very core of my objection. He hasn’t identified the warrants for his argument, meaning his argument is literally gibberish to people working from a different set of warrants. Dudebro here could learn a thing or two from Toulmin.
This is a problem endemic to techbros writing about tech. They assume, quite incorrectly, that the entire world is just clones of themselves perhaps a little bit behind on the learning curve. (It never occurs, naturally, that others might be ahead of them on the learning curve or *gasp!* that there may be more than one curve! That would be silly!)
So they write without establishing their warrants. (Hell, they often write without bothering to define their terms, because “trace” means the same thing in all forms of computer technology, amirite?!) They write as if they have The Answer instead of merely a possible answer in a limited set of circumstance (which they fail to identify). And they write as if they’re on the top of the learning heap instead of, as is statistically far more likely, somewhere in the middle.
Which makes it funny when he sings the praises of a tracing library that, when I investigated it briefly, made me choke with laughter at just how painfully ineffective it is compared to tools I’ve used in the past; specifically Erlang’s tracing tools. The library he’s text-wanking to is pitifully weak compared to what comes out of the box in an Erlang environment. You have to manually insert tracing calls (error-prone, tedious, obfuscatory) for example. Whatever you don’t decide to trace in advance can’t be traced. Whereas Erlang’s tracing system (and, presumably Ruby-on-BEAM’s, a.k.a. Elixir) lets you make ad hoc tracing calls on live systems as they’re executing. This means you can trace a live system as it’s fucking up without having to be a precognitive psychic when coding, leaving the costs of tracing at 0 until such a time as you genuinely need them.
So he doesn’t identify his warrants, he writes as if he has the One True Answer, he assumes all programming forms use the same jargon in the same way, and he acts as if he’s the guru sharing his wisdom when he’s actually way behind the curve on the very tech he’s pitching.
He is a, in a word, programmer.
