These line-conditioners actually perform well given the cost, but never buy used surge-arresters given the finite spike hit-count. Best of luck =3
So Tripp Lite uses a regular varistor for that, just like any other surge protector. In Europe you'd be far better off buying a voltage relay and adding it to your electrical panel, but it's not usually possible with the non-modular US electrical panels.
Some fabs are starting to reuse helium in downstream processes but there’s only so much they can do without expanding their core competency into yet another complex chemical manufacturing process.
MRI machines don’t need high purity helium and the contamination doesn’t “gunk up” all the tools so it’s not an issue to recycle it there.
Most famously illustrated by Intel's "Copy Exactly!" methodology. https://duckduckgo.com/?q="copy%20exactly"+Intel
An adjacent IBM story that kinda explains why:
During the year 1986, there was an anomalous increase in LSI memory problems. Electronics in early 1987 appeared to have problem rates approaching 20 times higher than predicted. In contrast, identical LSI memories being manufactured in Europe showed no anomalous problems. Because of knowledge of the radioactivity problem with the Intel 2107 RAMs, it was thought that the LSI package probably was at fault, since the IBM chips were mounted on similar ceramic materials. LSI ceramic packages made by IBM in Europe and in the U.S. were exchanged, but the European computer modules (with European chips and U.S. packaging) showed no fails, while the U.S. chips with European packages still failed at a high rate. This indicated that the problem was undoubtedly in the U.S.-manufactured LSI chips. In April 1987, significant design changes had been made to the memory chip with the most problems, a 4Kb bipolar RAM. The newer chip had been given the nickname Hera, and so at an early stage the incident became known as the "Hera problem."
By June 1987, the problem was very serious. A group was organized to investigate the problem. The first breakthrough in understanding occurred with the analysis of "carcasses" from the memory chips (the term carcasses refers to the chips on an LSI wafer which do not work correctly, and are not used but saved in case some problem occurs at a future time). Some of these carcasses were shown to have significant radioactivity.
Six weeks was spent in the manufacturing process lines, looking for radioactivity, and traces were found inside various processing units. However, it could not be determined whether these traces came from the raw materials used, or whether they were transferred from the chips themselves, which might have been contaminated earlier in their processing. Further, it was discovered that radioactive filaments (containing radioactive thorium) were commonly used in some evaporators. A detailed analysis by T. Zabel of some of the "hot" chips revealed that the radioactive contamination came from a single source: Po210 This isotope is found in the uranium decay chain, which contains about twelve different radioactive species. The surprising fact was that Po210 was the only contaminant on the LSI chips, and all the other expected decay-chain elements were missing. Hundreds of chips were analyzed for radioactivity, and Po210 contamination was found going back more than a year. Then it was found that whatever caused the radioactivity problem disappeared on all wafers started after May 22, 1987. After this precise date, all new wafers were free of contamination, except for small amounts which probably were contaminated by other older chips being processed by the same equipment. Since it takes about four months for chips to be manufactured, the pipeline was still full of "hot" chips in July and August 1987. Further sweeps of the manufacturing lines showed trace radioactivity, but the plant was essentially clean. The contamination had appeared in 1985, increased by more than 1000 times until May 22, 1987, and then totally disappeared!
Several months passed, with widespread testing of manufacturing materials and tools, but no radioactive contamination was discovered. All memory chips in the manufacturing lines were spot-screened for radioactivity, but they were clean. The radioactivity reappeared in the manufacturing plant in early December 1987, mildly contaminating several hundred wafers, then disappeared again. A search of all the materials used in the fabrication of these chips found no source of the radioactivity. With further screening, and a lot of luck, a new and unused bottle of nitric acid was identified by J. Hannah as radioactive. One surprising aspect of this discovery was that, of twelve bottles in the single lot of acid, only one was contaminated. Since all screening of materials assumed lot-sized homogeneity, this discovery of a single bad sample in a large lot probably explained why previous scans of the manufacturing line had been negative. The unopened bottle of radioactive nitric acid led investigators back to a supplier's factory, and it was found that the radioactivity was being injected by a bottle-cleaning machine for semiconductor-grade acid bottles. This bottle cleaner used radioactive Po210 material to ionize an air jet which was used to dislodge electrostatic dust inside the bottles after washing. The jets were leaking radioactivity because of a change in the epoxy used to seal the Po210 inside the air jet capsule. Since these jets gave off infrequent and random bursts of radioactivity, only a few bottles out of thousands were contaminated.
Polonium is debuggable. More subtle statistical aberrations would be exponentially harder.
I'm most familiar with software and home electronics debugging, but it would be wonderful to hear some stories from other disciplines where a culprit is found, and also about the forensic tools specific to other domains.

We have so much gas where I live that there are places it’s just flared off and burned, because it’s less greenhouse emissions than it escaping unburned.
Grade 6 (6.0 helium = 99.9999% purity) The closest to 100% pure helium, 6.0 helium is used in the manufacturing of semiconductor chips – Grade 5.5 (5.5 helium = (99.9995% purity) Like 6.0 helium, 5.5 ultra pure helium gas is typically considered “research grade,” also used in chromatography and semiconductor processing
Grade 5 (5.0 helium = 99.999% purity) This high purity grade helium is also widely used for gas chromatography, mass spectrometry, and specific laboratory research when higher purity gases are not necessary, as well as for weather balloons and blimps.
Grade 4.8 (4.8 helium = 99.998% purity) The highest of the “industrial grade” heliums, 4.8 grade helium is often used by the military. The rest is classified...
Grade 4.7 (4.7 helium = 99.997% purity) A “Grade-A” industrial helium, 99.997% helium is mostly used in cryogenic applications and for pressurizing and purging
Grade 4.6 (4.6 helium = 99.996% purity) Grade 4.6 industrial helium is used for weather balloons, blimps, in leak detection
Grade 4.5 (4.5 helium = 99.995% purity) Often the grade most commonly referred to when people say “industrial grade,” 99.995% helium is most commonly used in the balloon industry
Grade 4 (4.0 helium and lower = 99.99% purity) Any helium that is 99.99% and down into the high 80 percents is within the range of purities referred to collectively as “balloon grade helium.”
What is the reason that MRI needs grade 6 vs grade 4 helium? I'm imagining that the superconducting wire is within a cryostat filled with liquid helium. Doesn't seem like there would be any appreciably partial pressure of things like nitrogen or oxygen at 4 Kelvin. I imagine the reactivity of oxygen is pretty low at 4 K as well. How much dissolved oxygen or nitrogen can liquid helium support? And how much solidifies out and sinks to the bottom of the cryostat?
Turns out that you are right, some balloon gas is 80%. Specifically, the "Balloon Time" tanks you can buy at places like Target say "not less than 80%" helium.
On the other hand, I went to AirGas and a few other suppliers and they seemed to have 95%-97.0% helium gas as their definition for balloon grade.
Definitely worth knowing what you're getting, in any case, so you don't get ripped off, and so you can actually get that lawn chair contraption into the sky.
Moar hydrogen party balloons. Making partying fun again!
You have the entire collected knowledge of mankind at your fingertips. You could do 30 seconds of research and find an answer better than "I don't think that sounds right".
So could you, right?
More than just from inflation? (sorry, not sorry!)
One’d think that they’d keep more than a couple of weeks’s supply of critical materials —to bad many copied Cook’s and others’s JIT inventory management for everything.
After sales paid off the debt that has been incurred from the expansion of scope of the helium program in the 1960 Helium Act, which was one of the main points of the HPA, it was update by the Helium Stewardship Act of 2013 (which passed the House 394-1, and the Senate 97-2, and was signed by President Obama).
In the 1980s, I assume getting rid of the "strategic reserve" of anything would have met more pushback, because of primal fear overriding greed.
– Georgi Arbatov, Soviet political scientist, 1988
Kidding aside, the US has had libertarian pipe dreams for the better part of its history. The aberration was the New Deal period up until the mid 60s.
Sounds like Obama kept the gas taps flowing, instead of locking it up because authorization to sell it had expired. Here is the whole record: https://www.congress.gov/bill/113th-congress/house-bill/527/...

Messer Completes Acquisition of Federal Helium System from BLM | June 27, 2024 | https://www.messer-us.com/press-releases/messer-completes-ac...
In the best case, "strategic reserves" are the government speculating on commodity prices. They use tax dollars to buy a commodity -- raising the price on everyone so they can hoard it -- and then more tax dollars to pay for a storage facility, and if they're lucky the price goes up by enough to pay for the storage and the time value of money by they time they sell it again. That frequently doesn't happen.
In the common case it's the government subsidizing corporations -- including foreign ones -- by using tax dollars (at government contractor rates) to operate a storage facility at a loss so the industry doesn't have to do it themselves. Then, when they go to unload it, they generally unload enough to lower the market price on purpose, practically guaranteeing that the taxpayer is getting a below-market return. This unloading also has a statistical correlation with the election cycle (see also "strategic petroleum reserve") which is extra stupid. And the expectation that it will happen deters others who aren't paying government contractor rates from storing the commodity, so from a "strategic" perspective you don't get anywhere near as much of a buffer as you're paying for.
If the tech industry wants a reserve of helium then they should buy some land, install some tanks and fill them with helium in years when there isn't a shortfall.
But yeah, that would make more sense.
They have a patch strategy! They considered requirements when deciding the strategy! They have a documented strategy, it’s just very brief. (“Don’t.”)
The Trump admin may have similarly thought about this issue for a few seconds, shrugged their shoulders and decided that this might force manufacturers to go on-shore.
You and I know it won’t, certainly not in the immediate future, which means massive disruption to industry, but that’s not the same as “no plan”.
I understand the not burning fossil fuel thing, but why can't it be seen like another mineral resource?
This whole administration is such a fiasco.
And I say that with his permission, since he’s on camera asking to be called out if he did exactly what they did with the Supreme Court not four years later.
We are in here, because we didn't learn from our history. You feel this way because this is recent and its hitting everything all at once but I do feel like these were all very avoidable lessons. Being honest, I don't feel like we learnt anything new aside from seeing how the world is still trying to clutch itself back to stability even after all the instability Donald Trump is causing within the world (for better or for worse) and seeing how the world reacts to all of this live.
But I am not quite sure if future will learn from these lessons given that its feeling to me like history doesn't repeat itself but it often rhymes and we somehow don't really learn from the history to be honest.
I don't think I have ever heard a MAGA talk about AI.
Lots of ex-Bitcoin-bros turned AI hypemen went all-in on maga for Trump II. Even the silicon valley C-Suites and VC-class went mask-off around February 2025. Some have tried to walk it back since then, after realizing the administration they had hitched their wagons to didn't have the mandate or levels of public support they had hoped for - thankfully, the internet never forgets.
That is just a thought experiment, though, I do not believe it would play out beneficially if we tried to implement it in real life.
If you're not into social and demographic engineering, then you're going to face a real problem.
My solution would be to get it over with and shoot everyone who disagrees with the system I'm trying to build. It sounds childish but it does actually genuinely work. It has been put in practice in so many places it's easy to lose count.
What's the best way to have a sane system? I'm not sure. I personally lost all faith in democracy.
Sure, they might be better informed - which lets them figure out how best to corrupt the system.
Edit: in fact, I could see a strong reason to DISALLOW anyone in the top 1% to vote or spend any $$ towards the election.
Some of those people are not white and/or not straight. They - very incorrectly - think that wealth will shield them from the sharp teeth of White Christian Nationalism. They should consult with the Log Cabin Republicans and women who voted for both Trump and enshrining abortion into their state's constitution on the same ballot.
The correct way of putting it is so old rich suited men can engage in pedophilia.
That's it. That's the best they can do.
Even nominally selfish far-sighted things like genuinely funding a deep research program for life extension is not really something they're into. I mean some of them are "into" it in that they talk about it and occasionally toss money at things but they're not interested in funding or being involved in the kind of multi-year high-focus moonshot program it would actually take to deliver. The problem is that's hard and it takes a long time when banging girls and winning power games is instant dopamine.
It makes me keep thinking of paperclip maximizers. It's like we are paperclip maximizers, only our paperclips are sex and dopamine hits from winning power games. A paperclip maximizer with such resources would squander it all on paperclips, and we squander it all on these goal functions built in by evolution. Are we actually intelligent or just clever animals? We can seek what we want, but we don't think much about what we want to want.
Most either do nothing really of note, or donate it to "causes", which may be good, but kind of boring.
God does not come down from the heavens and bestow money that one spends on what one chooses. People value his companies because he’s there. TSLA will instantly collapse in valuation if he exits.
I’m not even kidding. If you can pass the regulation, environmental, land permits, local opposition etc. you will be a hundred millionaire maybe a billionaire.
As an aside this might indicative of today's defective rich. Carnegie built over 2,500 libraries for example.
> he gave away around $350 million (equivalent to $6.9 billion in 2025 dollars), almost 90 percent of his fortune, to charities, foundations and universities
Those famously "richest Americans" were worth single digit billions in today's money. Musk is reportedly worth $600-800 billions. Imagine what he could do with that money. The Gilded Age industrialists were already devils, but to say the quality of the ultra-rich today is in the gutter would be an offense to the gutter.
What makes Musk's wealth really incredible is how much of it is based on hot air (TSLA).
It's a tale as old as Plato: those most likely to WANT to rule are exactly the 'candidates' who absolutely should not.
One of the things this does is gets you surrounded by supplicants and yes-men trying to tell you what you want to hear to get your money. It destroys social feedback. Nobody will tell you you're wrong. This is not good for mental health.
Who would you be able to spend time with? Most of your friends and family would still have to work. Of course, you could offer them to leave their jobs and give them money so they won't have to worry and they could spend time with you. But then it leads to the social feedback issue, so even those closest to you don't want to rock the boat.
I really don't like how Bill Gates and Microsoft made their money, but at least he has realized that in his twilight years to try to make amends via humanitarian work. Buying the stairway to heaven.
Does the improved geopolitical landscape consist of closed strait of Hormuz? Not sure what else they can geopolitically achieve compared to how things were a few weeks ago.
I thought that they were being decommissioned due to seismic risks?
They may not have a house to heat if tremors get too bad.
And our German neighbors, I can still see them laughing at the Orange Man Bad... Boo hoo... what a shitshow.
If I lived in the region I wouldn't really care if the economic risk is single digit percentage. I would prefer my house to keep standing.
> they are actively and very costly going to fill them with concrete to ensure in the future (even in whatever extreme scenario) they cannot be used again.
I think you are arguing in bad faith. If you hollow the underground, filling it with something is a way to mitigate the seismic risk.
> And our German neighbors, I can still see them laughing at the Orange Man Bad.
Okay, I see now that talking to you is a waste of time.
Have a great afternoon.
Losing all your personal items and memories + living homeless for a few years while the reconstruction is in progress isn't minor inconvenience.
And I didn't say kick everyone on the street while the reconstruction is taking place. Everyone can stay where they are. Earthquakes are rare and so far in 50 years of extraction there have been no injuries. Groningen isn't the only place with earthquakes in the world you know?
16°C in itself doesn't have health consequences whatsoever.
> Only when the black mold started appearing did we manage to persuade her that 19 would be more appropriate.
And you made the wrong diagnostic: mold is a moisture problem, not a heating problem per se. Sure heating improve air moisture but it's a very inefficient way to do so. You're complaining about the cost of a problem when you're using the most inefficient possible method to address it.
And again, if world market gas price rise, the consumer cost of gas rise as well, no matter if you have gas production in the country or not.
Some jurisdictions even have “tenants rights” laws that literally force landlords to terminate all contracts whenever a tenant is about to have lived in a location for too long.
(to clarify, the concrete has nothing to do with the seismic risks, and is solely intended to make it impossible to extract gas later, which some people see as a valid way to lower potential seismic impact in the future due to no extraction... as if it is the only way to deal with seismic risks... and the whole point of the profits being ample to mitigate any economic loss is that people's houses can be either made resistant, or, you know, we could buy affected people a brand spanking new house)
Good luck with the rest.
This seems, uh, awfully optimistic.
Isn’t this the future sci-fi nerds were predicting? It’s just that instead of “unplugging SkyNet” we have “supply chain disruption”?
Maybe instead of triggering WWIII the AIs will force a peaceful resolution to major conflicts that disrupt the supply of their substrate.
The accelerators must flow.
"Let the lord of chaos rule" ...
In that respect they may be bombed by Iran but they have the same interests
And as far as I understand, helium is a byproduct of the extraction, so they can't choose to keep only the helium.
Or let's make the analogy clearer: if your Uber driver cancels the ride because there's an active shooter on the only road between him and you, it's their fault not the shooter's?
your analogies have went past me though, generally although a common misconception, countries are not people and wars are not comparable to crime
To restore traffic, we need that risk to return to previous levels, which requires diplomacy and trust. I don't expect resolution any time soon.
--- Hegseth: “The only thing prohibiting transit in [Hormuz] right now is Iran shooting at shipping.”
“It is open for transit should Iran not do that” ---
Oh really? I thought it was because Mercury was in retrograde.
I guess if even Mr. Hegseth is admitting that transit is effectively prohibited in the Strait, he must actually be lying and part of the deep state.
I also find it funny that we just decided to allow Russia to pad its coffers by temporarily lifting sanctions on sale of Russian oil. Sorry Ukraine!
