stefs··on Who needs Graphviz when you can build it yourself?
this tool works by replacing the "general purpose" algorithm by specializing it, which made it less general purpose but simpler and more efficient ... and now there's the request to make it more general purpose.

(it's a joke! and the joke is that those are two different general purpose. but still.)

stefs··on French ex-president Sarkozy begins jail sentence
on the one hand you have the owner dictating his political bias to all his employees/journalists. on the other hand you have a person/journalist interpreting reality through their own political bias. what's the difference? in the first case the medium would only report biased in one direction, in the second case it'd report roughly split around the percentages of the (journalistic) population, e.g. 60% this, 40% that.

well, the chinese outsourced hog farms (pork production) to the U.S. because the farms are considered too toxic and environmentally destructive for them.

I'm not sure I get you - "not 0" is a more predicable value than a certain number, isn't it?

it may be possible to add - or rather, that they've already added - an mcp function that clears the context?

that is not the same.
stefs··on The Great Horse Manure Crisis of 1894: predictions of 9 feet of manure in cities
> The reasoning was that more horses are needed to remove the manure, and these horses produce more manure.

i think that even then, that's not a problem, as one horse drawn cart can remove a lot more manure than it produces, i.e. a small number of extra horses can remove the excess manure of all horses and the overhead the extra horses introduce is mimimal.

stefs··on JSON River – Parse JSON incrementally as it streams in
but you don't do this for strings either, as shown in the examples - partial strings are pushed even though they're not yet ended:

cool! how does this compare to dokploy? same niche or are there important differences?

That mustn't be the primary key, though, but a serial that counts (and is unique) per-customer.

stefs··on Hyperion: Minecraft game engine for custom events
I don't think so, as the unit of simulation are chunks, and only chunks near players are stimulated - at least in classic Minecraft. I.e. if all players are in one chunk only one plus the surrounding ones are stimulated, but if all players are spread far apart, you have the same simulation workload for each player.

Or is this different in Hyperion?

stefs··on Hyperion: Minecraft game engine for custom events
> "In the worst case" ...

in the average case it should only be a fraction of that, because otherwise why multiplayer. they also mention "events" a lot, so i guess this isn't targeted towards normal run-of-the-mill minecraft play but special events like those society simulation experiments you can see on youtube, which are usually quite condensed.

still, the question is, how much faster is rust at world simulation? they mention vertical scaling, so i guess it's somewhat limited.

stefs··on Rules for creating good-looking user interfaces
regarding "go beyond 'do these align'":

> This system is about achieving the best possible design with the least amount of effort. There’s no need to know about the psychological impact of colors, which fonts are best for which purpose, golden ratios, etc. This is expert-level design knowledge that is just distracting if you’re not on that level. The key is to focus on the few important aspects, and not try to optimize every tiny detail.

more bike oriented, but that often overlaps with city planning and design:

stefs··on Pontevedra, Spain declares its entire urban area a "reduced traffic zone"
i haven't made that experience at all, as i've got kids and pretty much never used the car for inner city trips. trips are daily kindergarden, doctor, visiting friends - we do all those with either bikes plus a kids trailer or public transport (i'd say roughly 50/50).

for the kindergarden commute we've used the car two or three times in almost 5 years, when we had to transport birthday party stuff (i.e. cake), but then we stopped even doing because using it was too much of a hassle.

stefs··on Pontevedra, Spain declares its entire urban area a "reduced traffic zone"
> close by villages, max 5km

a good cycle path would do wonders there. a flat 5km ride is doable for almost everyone, including seniors and children.

regarding jobs: that's got nothing to do with the carless center. to the contrary - for remote work, it'd be perfect.

stefs··on Pontevedra, Spain declares its entire urban area a "reduced traffic zone"
as far as i know, e-bikes (does that count as a motorized vehicle?) are more dangerous per kilometer traveled (especially if the infrastructure is lacking and not to a small part due to predation from cars, but most of the bike accidents happen without a second party).

compared to driving, riding a bicycle is very healthy so the net effect for bicycling is still positive.

stefs··on The demo scene is dying, but that's alright
i've attended a (very small and local) demo presentation and Q&A once and, of course, asked whether the demo scene was dead. the presenter said the demo scene has been declared dead for years already.

that was probably over 15 years ago.

stefs··on I accidentally became PureGym’s unofficial Apple Wallet developer
it's probably a random app development studio. the gym most likely doesn't employ their own app dev employees. the app developement studio basically cares about two things: earning money and keeping their client just happy enough so they come back. the users of the app are not their customers and at best a secondary concern.

wouldn't work for me because i usually don't have my gym bag with me when i don't plan going. have a regular schedule and a program with a progression scheme.

stefs··on Tour de France confronts a new threat: Are cyclists using tiny motors?
yeah, i think i'm convinced.
stefs··on Tour de France confronts a new threat: Are cyclists using tiny motors?
i'm unconvinced. EPO was undetectable, but not anymore. new undetectable substance would run the risk of being detectable in a few years. who would ignore whistleblowers today? and the USADA did bring the hammer down on LA at some point.

sure, they pay off is high, but the risk - at least in cycling - is even higher, exactly because they've been caught once and now all eyes are on them. if pog gets popped, nobody will trust cycling to be clean ever again; it's hard enough today, as this thread proves.

stefs··on Tour de France confronts a new threat: Are cyclists using tiny motors?
this also supports my point, though: armstrong got caught. he was stripped of all his titles. there were whistleblowers (even though they were ignored back then). everybody knew they were cheating but nobody did anything about it ... well, until they did.

i don't know how hard pro cycling was affected after his bust, i just remember reading that it took a few years to recover (i.e. a few teams got dissolved, some sponsors jumped ship).

even today, if you talk about cycling to an outside person the FIRST thing they ask you about is doping.

so in my opinion, professional cycling is on its doping redemption part - forced, whether they want it or not - because if they (and by "they" i mean Pog) get popped big time again, it's going to be viewed as irredeemable. they'd have had their chance after LA and blew it.

stefs··on Tour de France confronts a new threat: Are cyclists using tiny motors?
ah, the magic undetectable drug that's just the right kind of effective without the pesky side effects, which you'd need other undetectable drugs for.

this drug would be worth a lot of money, but we'll keep secret except just for the one top performer, because wide distribution would increase the risk of a leak substantially.

and remember: the top performers getting busted would probably mean the end of pro cycling as we know it for decades. cycling isn't a huge money maker for financial investors like football, rather it's a money pit for sponsors. do sponsors love a podium placement more than being forever associated with dirty cheaters? they'd risk it all for modest gains. a young superstar would trade a life of a good salaried position with some more money but also a high risk of being banned from the sport forever, thus no source of income at all and also the questionable title of being the killer of a whole sport.

so imo: it's possible, but unlikely.
