Some mods in modded minecraft had that and it's a very punishing mechanic unless implemented well. It eats all of your power and usually also very expensive items very quickly usually. Assume you have like 600RF/tick generated, common with certain generator constellations. 1 tick - 1024 RF and one input consumed, crafting fails due to not enough power. 1 tick wait, 1 tick, 1024 RF and one input consumed, ... This can…

GT:NH has “easy mode” enabled in some regards - it won’t finish the craft but it WILL wait for power (actually keep trying) - so if you fix the power problems you can finish and not lose the mats. May or may not apply to multi blocks.

I didn't finish GT:NH but if I ever set aside enough time to play a GregTech build again, GTNH is on the very short list.

Power brownouts are pretty rare outside of the very early game. It's too easy and cheap to massively over produce power for that to really harm players outside the early game so I don't think there'd be much interest. Usually brownouts rapidly develop into full blown blackouts and black restarts as your miners reduce output during the brownout often leading to a reduction in incoming fuel leading to even less power b…

I would apply it to inputs as well. Suppose you can start production with only 1 of each input required for a recipe, but to keep it going you need to keep feeding all of the inputs to finish it. If any of them run out, then the recipe fails, you lose the inputs, and the machine stalls. This works better for high latency recipes (>10s) with lots of inputs, like low density structure, modules, and atomic bombs.

Usually the answer is to just slightly overproduce the inputs, only the new planet Gleba even slightly discourages letting items just sit on the conveyors with their freshness mechanic. What's the benefit?

This was apparently a Linde installation custom built for TSMC in Arizona.[1] Nitrogen, oxygen, and argon are extracted from air on-site and purified. That's Linde's primary business; liquefying and distilling air. This isn't some little local company or a company operating outside their area of expertise. Those gases are storeable, so it's surprising there wasn't enough tank capacity to deal with outages. The site p…

Unless things have changed a lot since I fled semiconductor manufacturing, you would still need silane tanks at least. I’m as surprised as you that they don’t have buffer tanks.

Why did you use the term "fled"? Any interesting story?

From the outside, I would love to participate in semiconductor manufacturing.

Multiblocks power fail and void, but then your machine shuts down until you restart it. This is much better than suggested above, where you'd void over and over, but it can still utterly mess up a large craft being orchestrated thru AE2, which is still waiting forever for he failed craft to submit a part back into the system.

I don't think Linde™ needs an add, everyone knows Linde™ is the most reliable partner in producing and storing gases in all available purity classes. (joke off, it's probably not an add, but they were excited to share the reason you see Linde on all sorts of gas tanks all over the place. It's actually quite common and if you see it once you see it everywhere. )

I've never seen Linde ever in my life (Australia). What is funny though, at least in the Australia and UK regions, they still use the BOC brand, which is a subsidiary under Linde.

Competitors in the space in Australia include Air Liquide and Supagas.

Supagas tend to have better prices for smaller operators, and hobbyists.

This isn’t very big news. Issues occur during bring-up often. Linde’s processes are possibly so power intensive that failing over to generator power is not possible. TSMC is right to put Linde on notice since Linde should have a PFMEA and control plan to eliminate any root causes for downtime. I suspect in the long term TSMC has plans to insource this if the issue persists. Scrap happens sometimes during manufacturin…

> After all, the TSMC logo features failing parts! I'm not sure about that, I think the blank spaces are just parts that have been picked. The dies have been cut and the good ones are being removed.

Normally a wafer would have die-sized spaces for test structures used for optical, electrical, chemical and other tests. Think the TV test card https://en.wikipedia.org/wiki/Test_card

That is not what I heard from my cousin at TSMC. The OT gives the workers a “living wage”. Most of his coworkers charge OT every week of the year. He admitted, even with their OT and bonuses, he probably makes more than them w2 salaries. But my point still remains: if they want US (or TW) folks to work more hours, they need to pay for those hours.

https://www.reddit.com/r/Semiconductors/comments/18x5vr5/sem... This reddit post captures what I've seen at TSMC in Taiwan. $120K is normal pay at the director level...engineers make $2500-5000 a month. TSMC AZ starting pay for a new college grad w/ BS is probably just under $100K/year with just salary, with the potential to make over $120K within a few years with full vested bonuses.

I think your numbers match what my cousin shared. In both my conversations with my cousin and in the reddit post, it is unclear if reported salaries are take-home or don't include the OT and bonuses, but I don't get your point?

My point is: Engineers in Taiwan work more hours because they are paid to work more hours (OT). Engineers in the USA are not paid more if they work 35 hours or 60 hours.

If TSMC wants to address the culture gap (get the Americans to work more), TSMC should pay up.

You would want to use circuits and stop production if there aren't enough inputs for a receipt.

It still looks kinda easy, the machines just do it automatically on the default game.

Linde was definitely around as a distinct brand in Australia before they bought BOC in 2006, but since then as you said, they now just trade as BOC.
