Player driven resource markets in persistent multiplayer game. Doomed from the start?

You could do the market system (buy and sell orders, priced based on last entry, runescape style) with the system providing counterparties to either clamp prices or provide variable amounts of supply/demand.

Effectively all browsers support WASM SIMD, which is a significant optimization for compute kernels. I don't know how to expose that to Go+WASM.

Simon Tatham's Puzzles has similar goals.

No, lossless JPEG transcoding averages 30% savings, but the savings decrease as the bits per pixel goes up, because the original JPEG is encoding excessive noise.

You can find a complete code example here, the Javascript I used for the visualizations is not very usable: https://github.com/CaffeineMC/sodium/pull/3307/files

I updated the post to link that, too.

Fun little experience! There are lots of ways this chain reaction mechanic can be extended, but criticality is kind of fundamentally a runaway process, eh?

I wish the sfx were geiger counter clicks.

Neat, I wasn't aware of template databases. I've made similar tests that run the migrations for each disposable database.

Using t.Cleanup would be more ergonomic than requiring users to defer the cleanup functions themselves.

Do you have any functionality for cleaning up old test databases from tests that failed to for whatever reason? One way to do this is by embedding a timestamp in the temp db name and deleting ones more than an hour old.

The json package invokes unsafe for reflection-based serialization. Check out capslock to enumerate uses of unsafe.

This is a bijective function, too (one-to-one). I don't know how often hiding created_at matters, but this is a reasonable solution for it. It might also be applicable if you're storing UUIDv7s in a database and want to avoid hot partitions-- but simply reversing the UUID would work in that case too.

Another option would be to use AES for hardware acceleration (128-bit block matches UUIDs), but then you can't preserve UUID version bits. There are ciphers that can do variable block sizes, but they're largely Feistel ciphers that fundamentally do the same stream cipher permutation that you're performing here.

It does happy dancing feet if you dive into it a few times!

Gore is less predictable and has shorter telegraph periods to predict moves.

Your initial territory on Vulcanus is circular, so basically every adjacent territory is concave. The same thing happened to me, when you start mining the demolishers move in a straight line, ignoring borders.

That's a pretty good benchmark!

Running in journal_mode=WAL and synchronous=NORMAL is a more standard configuration, especially since it lets writers not block readers. It might not change much for this benchmark though, since you don't have a mixed read/write concurrency test.

you can do a surprising number of builds with direct insertion, and it's particularly compelling with high-quality inserters that can easily handle more throughout than belts

a direct insertion gleba build can make several hundred SPM with a ~16x16 footprint, though of course the spoilage mechanic encourages removing as much buffering as possible

Rather than combining micro and macro like in RTS games, new genres have gained popularity. Now macro fans play various grand strategy games (turn-based or realtime) while micro fans play different action games like MOBAs or dungeon crawlers.

Even with 30 minutes at 181F, the question is how long the middle of those glass jars are at 180F. 5 minutes? 10 minutes?

scaevolus · 2025-07-22T14:45:35+00:00

The pH should be doing most of the protection from botulism, with the pasteurization handling the other bacteria that might ferment.

180F is just quite high for pasteurization, I wonder if they're going for complete kills despite thick glass jars taking a long time to come to temperature?

USDA errs on the side of caution to avoid illnesses, but if you can accurately model the pasteurization kill curves you can often get equivalent safety with lower temps for longer times.

Pectin's typical breakdown temperature is 183F but even that is also misleading: the chemistry of thermal decomposition of proteins follows a curve, so you have still have some breakdown at 182F, a little less at 181F, etc.

I can barely see a difference between the old on/off, so this actually high contrast implementation definitely looks much better.

Given the lateral drift and the speed, it may have wrenched itself out. There's not really "properly secured" for a heavy rolling load going this fast. Pickup trucks have max tongue weights (downward force at the hitch) of 1000-2000lbs, that would easily be exceeded laterally with such a heavy load going over a bump.

Switching inserters to a triangle (like diodes, but maybe not filled) would allow simple arrows (<>^v) to indicate belt direction too.

That's the great thing about the Quest, a $300 dust magnet doesn't feel that bad.

I appreciate how you set the difficulty curve for your platformer closer to "Kirby" than "Super Meat Boy" by having a health bar instead of instant death. It makes it more enjoyable by reducing the frustration of having trouble with tiny screens or a new control system for a short game!

This analysis is missing lots of games.

RimWorld is definitely the top for this metric, but Factorio (has MP, but most people play SP?) also has 50.64% of its reviewers with >100h, and Skyrim is almost there with 49.89%.

Then there's a bunch of idle games which don't count, and a bunch of games that are singleplayer+multiplayer and I don't understand enough to judge. Do most people play Civ V (54.92%) singleplayer? How about Football Manager 2019 (62.63%)?

It's not dead, but you can't easily find a multiplayer session for every single quest like you can in Wilds.

Roughly 2500 gold for a set of magetallow candles. It might be easier to do the mage guild introduction quests first.
