PSA: legendary burner inserters are fast enough for green belts. (AKA 2862MW solid fuel power)

Remember this delight from back in the day?

https://www.reddit.com/r/factorio/comments/enpeov/i\_see\_your\_216\_mw\_boiler\_plant\_and\_raise\_you\_a/

Well, as it turns out, you can do the same thing using legendary burner inserters, legendary boilers and stacked green belts and get 636 x 4.5MW = 2862MW of steam.

You do hit issues of pipeline length though, so have to 'split' it about 3/4 of the way up. I've included a pumping array to highlight how much steam is up there, but it'd be way more sensible to have parallel banks of chuffers so you don't need to bother pumping.

Water is still fine with a single pump per 'line' as 8 columns of boilers with an offshore pump each is sufficient - even legendary boilers only use 15/sec, so that's a total of 8 offshore pumps (and thus 8 'inline' pumps at the break is sufficient).

Leading to things like this:

Sure. It would probably be way more sensible to use heat towers, but where's the fun in that?

Will attract biters to come and play from a rather substantial distance.

40MW 'high efficiency' stored-heat reactor for space platforms (2.1 version - but viable in 2.0 with minor modifications)

So maybe a bit niche, but IMO one of the downsides of 'nuclear powered' space platforms is fuel efficiency. They don't need (generally!) the 480MW of a 2x2 reactor, but if they did have a 2x2 they could have 300% fuel efficiency on those rocket delivered fuel cells.

(and yes, I know, rockets get cheap later in the game, but at the same time temperature controlling reactors on Nauvis is a similarly not really necessary)

So a design concept:

  • 2x2 reactor.
  • A 'brick' of 152 heat pipes.
  • 4 heat exchangers. (converts heat at 40MW)
  • 7 turbines. (for 40MW of power)
  • 1 steam tank to smooth out any latency.

Like this:

https://factoriobin.com/post/1qvs6g

Will consume 96GJ at a time, on a temperature trigger, using 'heat pipe' temperature. Actually heat exchanger might be more sensible, but it should be the same. Reading the heat pipe adjacent to the furthest heat exchanger to ensure all 4 can always supply steam.

Can be expanded to do more than 40MW - it's a 2x2 reactor after all - by adding more exchangers and turbines. You might get away with fewer heat pipes in practice - 152 is the needed amount to 'buffer' 96GJ from zero, but if you're actually using power you won't need that full amount. (Heat exchangers also buffer the same amount as a piece of heat pipe, so technically it's 148).

And of course you can add more exchangers/turbines if you need more MW than that - it'll sustain up to 480MW after all

But the idea here is that you'll maybe be using the readily available solar power most of the time - even an Aquilo trip you're going from 200% to 60% over the leg from Gleba, and just using your 'stored' power from the nuclear when you need it.

Does angle of turn matter for trains?

Imagine you're making a 90 degree turn in your train. Does it matter to train speed if the corner is as tight as possible vs. a more gradual turn?

Intuitively it feels like trains might need to slow down for tighter turns, but I can't really tell if Factorio cares.

Second Foray into modding: Calcite bacteria

2 new recipes - gated by 'bacteria cultivation'.

  • Calcite bacteria (takes fruit mash + calcite and is horribly inefficient)

  • Calcite bacteria cultivation - uses bioflux and breeds bacteria like iron/copper bacteria, so 1 bacteria + 1 bioflux -> 4 bacteria (6 with biochamber productivity).

Bacteria decays into calcite (just like iron/copper bacteria).

Both 'gated' by reprocessing (unlike iron/copper bacteria) because the calcite cost of starting up is high enough that it's just a terrible idea to even try until you can cultivate - you'd be spending 10 calcite to get 0.1 calcite bacteria, so it's a great way to waste a load of calcite but not much else.

Motivation: Calcite 'manufacture' on Nauvis/Gleba so you don't just have to import it. (Of course you might need to import bioflux to Nauvis still, but 1 flux for 6 bacteria before prod is still less logistics - I'm thinking I might add more mods in future *).

Also: Gleba is the best planet.

https://mods.factorio.com/mod/calcite-bacteria

Probably makes the game easier - a lot of mods do that. But I don't think having a local source of calcite is crazy OP compared to importing it from Vulcanus/Space Platforms either.

* My 'fantasy' here is a mod bundle that enables 'full chain' manufacturing on Aquilo without needing imports, and that involves assorted bacteria, also maybe a 'greenhouse' that's expensive/lategame/promethium and an energy hog, but that grows gleba-fruit (less efficiently than an agri tower). Making a decent sprite is a stumbling point though, so we'll see...)

Camping shops in the area?

I'd have gone to Go Outdoors, but that has ceased to be. (In Oxford).

I'm looking to buy some decent quality camp chairs, which means I need a larger store I think, just because of 'inventory size'. Ideally sitting on a few to ensure they're sturdy, but also don't cut off circulation in the legs, and are generally comfortable.

Can anyone recommend me somewhere to visit?

Doesn't have to be in Oxford - anywhere within a sensible drive will suffice.

Getting started with Kislev?

So it seems I suck at the Kislev early game. Get bonked by one of the 'neighbours' well before I've any hope of tier 3 units, so am fending off a drycha with kislevite warriors and kossars (archers) and maybe a few light cavalry.

And it just seems to get messy every time.

Is there a trick for surviving long enough that I'm missing?

Does anyone actually still run 'isolated' (sort-of-airgapped) networks for 'business' use?

I use the term 'airgapped' loosely of course, because I've literally never seen a true airgap, just a bunch of ... virtual airgaps?

y'know, where between firewalls, vlans, etc. there's no direct access to the 'outside world' or maybe even to the 'dirtier' internal realms in some cases. (As much as one vendor tried to convince me that an automatic system to configure/deconfigure network ports counted as an 'air gap' I remain unconvinced).

But over the last few years it's got iteratively harder to keep up with the plethora of 'new stuff' that's daisy chaining dependencies, or pulling in stuff from multiple sources, or indeed the number of applications that simply don't function without some kind of 'call home'.

And do you also do that in userspace at all? E.g. we've a software development environment that's deliberately isolated from our 'browsing the internet/doing email' environment, and this too is getting ... kinda fun, between packages, libraries and not least the ravenous hunger for LLM tools.

Our reasons are a combination of security, DLP and audit/compliance requirements. It's not impossible to circumvent the controls of course, but it's at least somewhat harder to happen by accident or without getting noticed. (And yes, that's utterly at odds with 'but we want LLMs!' which is an entirely separate rant).

But I guess I just wanted to whinge a bit at the number of applications/vendors etc. that don't really seem to understand what 'standalone installation' actually means.

Is art assets the hardest part of modding?

So I have looked at modding factorio, and cobbed together a very basic one. (That allows biolabs to be placed on Gleba).

I am honestly impressed how easy it is. I shouldn't have been surprised at that, but still....

The stumbling point seems to be artwork though.

Like if you want to create a new building, you need 4 rotations potentially, maybe a "frozen" state, perhaps animation for operating etc. more so still if you want something like a vehicle with multiple rotations etc.

All a lot more complicated than overriding a built in.

I haven't a clue where to even start, so real kudos to the modders that add things like that.

Contacting your MP is one of the few forms of direct political influence available to us!

So I've said it before in a few threads, and I appreciate it's easy to get jaded by 'politics'.

But casting a vote every few years is really very minimal amounts of 'political influence', and does almost nothing to improve circumstances for a minority issue. Which ADHD is - at most it affects 3-4% of the population directly, and maybe a few more indirectly.

Petitions? Sadly don't work well either, for much the same reason - it will always be hard to accumulate popular support for an indirect issue.

But writing to your MP? Well, I don't want to get you hopes up too far, because you are just one person in 65 million.

But to your MP you might be only one in a few thousand, and if nothing else, they want to be re-elected.

And y'know, it's their job to represent your interests as their constituent.

Writing to MP:

  • They usually have caseworkers who can 'investigate' issues for their constituents. E.g. asking questions of particularly public sector bodies about what is supposed to happen, and how to achieve a positive outcome.

  • They can ask questions of Ministers and raise matters in Parliament

  • They also contribute to party policy, and 'feedback' from the voters helps inform policy and future manifestos.

Parties work really hard to try and figure out important issues and get feedback on policy, so they absolutely pay attention when you supply that information to them.

It's also very easy to contact your MP:

https://www.writetothem.com

If you can't think what to say, my usual suggestion is to try and keep one 'issue' per contact - so they can reply/respond without needing to pull together multiple disparate questions

Aim for 3 paragraphs (or sections? But don't overdo it - longer isn't always better!):

  • Outline the general issue you're writing about for context and clarity. If you've more specific information that's general, like say, how long lead times are in your area, or how many patients are 'seen' each year, add that. Freedom of Information act requests can gather this information, although it can be a bit frustrating trying to figure out who to ask https://www.whatdotheyknow.com/ *

  • Be specific about how it's hurting you, as their constituent - their job is to represent you, and it's just generally more impactful to explain how you're hurting, than trying to be general about it. Limit this as much as possible to people within their area of responsibility, although if you're aware of specific issues in the 'local community' (e.g. at school or similar) that might also be worth adding.

  • Then, if you know, be specific about what you'd like them to do. Maybe what you need is some advice on 'so what should I do?' or maybe you want them to tell public sector bodies to knock it off with their disingenous bullshit. Maybe you'd like them to consider amending a law or asking a Minister or raising it as party policy.

(Just generally though, they're politicians - they're quite adept at spotting bullshit and co-ordinated campaigns - an authentic communication gets a LOT more weight)

And genuinely, it's not as hard as you think. It's not a lot of influence - because ultimately you're one person out of 65 million - but your voice is now louder than the very vast majority who don't vote and never contact their MP, and that's worth having.

* FOIA results are also published, and can maybe be forwarded on to journalists who might be looking for a story on a slow news day.

"Fast Entry" rules and their impact on index funds

So I've been on the 'index fund and chill' bandwagon for a while now, and I broadly accept a market equity tracker has been a sound strategy so far.

However I'm now looking at some recent rules changes for some markets around rapid buy in.

https://www.lseg.com/en/insights/ftse-russell/faster-large-cap-entry-to-the-russell

Specifically that where previously there may have been some considerably delay for 'new entrants' to the market to be included in indices (and related - being purchased by index funds), now the timescales are much shortened.

Implicitly some upcoming large IPOs will be relevant here. As they rapidly enter the index, a tracker fund is now going to need to rebalance more quickly and predictably (e.g. allowing for trading against them). A company valued at ~2% of the S&P total capitalization could have a noticeable effect perhaps?

I'm wondering if anyone has any thoughts on the matter, as to whether these new policies do in fact, make index funds more (or less?) vulnerable than prior?

Can someone give me a really noddy guide to making multi-purpose trains?

So I've done train stuff, but mostly it ends up being 'the copper train' that moves between outpost and drop off.

It extends - slightly - as I add more outposts to the route, and more drop-offs, and maybe conditional enable/disable of stations.

But it's still pretty fundamentally a 1 job per train sort of approach.

Oh, but now I've added an interrupt to 'refuel'.

So what I'd like to know is the basics of how you set up a train that 'does what's needed' E.g. one train for the whole factory - that then extends to making multiple trains with the same 'setup'.

Is this best done with interrupts? Circuits? Do I need a radar to 'signal' that there is both demand and supply?

I know these seem pretty basic questions, and I don't want an extensive solution, just a hint on the starting point.

PSA: Gleba power generation (electric and nutrients)

The thing that got me to appreciate Gleba was this:

  • 5 Yumako mashers 1 fruit per sec -> 3 mash per sec, total 15 mash per sec
  • 5 jellynut squishers 1 fruit per sec -> 6 jelly per sec -> 30 jelly/sec

Consume 1 fruit per sec each (so slightly less than the peak output of a single agricultural tower) but they produce the right amount to run:

  • 6 bioflux makers (produce 6 bioflux per sec, consuming 15 mash and 12 jelly per sec).
  • 2 nutrient makers (consume 5 bioflux per sec to make 60 nutrients per sec)

This leaves you with a surplus of 1 bioflux per sec and 18 jelly per sec.

Which conveniently will let you run 5 rocket fuel biochambers, consuming between them 1 bioflux per second and 15 jelly per second.

0.75 Rocket Fuel per second (Each chamber makes 1 every 10s, but with a 50% productivity bonus) gives you 75MW, and that 3 jelly surplus is another 3MW. 5 burner towers will consume all 78MMW and output 195MW, with just a little headroom to take care of any spoilage coming through.

Adding modules (or beacons) will be fine as long as your config maintains the ratio (although you might need more heat towers).

60 nutrients per sec runs 240 machines before mods/beacons, less the 23 I've just listed, so you can run a fairly substantial amount of 'factory' off off this. You can setup a 'kickstart' using a nutrients-from-spoilage assembler, which will restart the process, but it can easily be 'self clearing' by routing any spoilage the same way as the rocket fuel (and in doing so, the nutrient production won't actually stall, and your power won't actually stop)

Related PSA: Nutrients don't burn in heat towers, but they can be run through a recycler and turned into spoilage, so you can 'terminate' any nutrient belt that way, so it is always 'flowing'.

A Khorne campaign in two screenshots

Have to manually fight most, because AR picks on my Ghorgon.

But still, 44s victory non ambush is still pretty good I think.....

Most cathartic faction?

I'm a simple person. Sometimes I just want to smash things.

Minotaurs do the job fairly well - their speed and charge animations are quite pleasing, and you can get get stalk stance if you're beastmen.

Although with Goregreed as Khorne, they get regen so that's nice too, and Khorne also gets some nice smashy-chargy chariot units.

Slaanesh (Dechala) I likewise find 'pleasing' because she too can get 'stalk stance' on one army, and do more or less the same thing with heartseekers and/or exalted chariots (aluresses on exalted chariots get to pop a locus and drop some debuff spells as well).

In each case I've had some pleasingly short battles where a whole army is smashed ludicrously fast, and that's ... just kinda fun.

(Aluresses on Exalted Chariots playing wacky racers around a city is also highly entertaining)

But at the same time, Chorfs with Dreadquakes and Blunderbusses also seem to do pretty well. There's a pleasing 'kaboom' as the dreadquake shells land, and then you run them over with a train. And if they happen to get into blunderbus range, pretty much everything gets shredded ridiculously fast.

I'm sure there's some caster options here too of course - some of the 'big nuke' spells are similarly potent enough/fun enough to just really appreciate a bit of delicious overkill. Although I guess they tend to be at least somewhat self limiting due to WoM availability so I've not really found one I feel can just 'spell spam' the way I want to. (Although in fairness, I've not played Gelt or Teclis for a LONG time, so maybe I should... but Elspeth...)

Honourable mention for undead, which rather plays into my gleeful 'smash everything' with an army of disposable chaff which I can safely ignore, whilst a couple of elite units smash all the things. I just have a soft spot for the Black Coach, because I just love the irony of mass murdering with a hearse.

So I'm sort of pondering - which factions for you, do you find most therapeutic to play?

Not for being strategically well balanced, or an otherwise 'reasonable' battle, just a ridiculous doomstack with a satisfting amount of 'wreck this'?
