Should we stock up on opamps, regulators, DACs?

So let’s buy some op-amps instead of sugared soda - while you still can. It is clear that we will ALWAYS be able to find food/drink laced with high fructose corn syrup. But when your favorite op amp is NLA because the market has decided to drop them in favor of something else - you just might not be able to get any more. You can’t diet them back either - and a daily marathon might help the frustration, but doesn't actually help the supply problem.

Have you tried the discrete op-amps from Burson?

I've collected one of their entry level amps, DAC and years ago I picked up their open chassis "evaluation" headphone amp / preamp. It's really easy to swap the opamps in those units. The eval unit makes it trivial.

I've also picked up a collection of their V5, V6, etc... they truly change the sound.

I get emails from them whenever they go on sale...
 
Apart from the health issues, and to answer the initial question, only th-parts for fixing/modifiyng/inventing, with proven quality. Semi's like 550/560 (C), 139/140 (-16), 1943/5200, 2N5458/5460, and this week 60x 2SK58 (expensive, above the war chest, packed in alu tubes) and 100+100 J74GR/K170GR (sub 200, 4 weeks).
A ticket to the Paradise of the Antipodes, also.
 
To grunf:
Do you know how to extract oil from olives in a primitive way? I have several olive trees and would like to try extracting some oil without equipment as in ancient times. Is it possible? When I crush some picked olives with a hard stone it is clear the result is oily, but how is the oil extracted and collected?
First, you need to grind the olives together with the pits and cold press the mixture, I think small home presses have appeared and work at a pressure of 60 Mpa.
Water should be separated from the resulting cloudy liquid with a centrifugal separator or let the liquid stand and collect the oil from the top when it becomes clear. The oil must be stored in a glass or stainless steel container, never plastic.
good luck
and if you want more info send pm

It is a ongoing story for some years with olives now, which can withstand droughts very good:
https://www.oliveoiltimes.com
It is true that the olive tolerates drought very well, but it still needs rain in certain stages of olive ripening, the absence of those few rains leads to drying of the fruit, disease, poor yield, i.e. the percentage of oil. It can also be damaged by too much rain.
In the picture from the link, you can see the green grass under the olive trees in harvest, but in my olive grove it's the same as in August, everything is dry and fried, there are still people on the beaches, and the crickets in the pines are still singing the summer song.
On my island, real rain hasn't fallen since last autumn and the most important autumn rain was absent this year, unfortunately not only olive trees were affected, but all vegetation, which resulted in huge forest fires that are impossible to extinguish. This summer my father-in-law lost over 50 olive trees, literally 40 years of work went up in smoke.

Just one example of "how modern science works" might illustrate the need to resurrect traditional education. Glyphosate, present in about every human body on the planet has been patented, https://patents.google.com/patent/US7771736B2/en and one sentence reads: "Importantly, the growth of these parasites can be inhibited by the herbicide glyphosate, suggesting that the shikimate pathway will make a good target for the development of new anti-parasite agents". Another one, "The shikimate pathway is an ancient pathway that is involved in primary and secondary metabolism and is found in all prokaryotes, many lower eukaryotes, and plants, but not in mammals."
The shikimate pathway exists in gut bacteria aka the gut microbiome, present in all mammals https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5972442/ and it gets worse than that, with "gut produced antimicrobial resistance" (by glyphosate): https://pubmed.ncbi.nlm.nih.gov/33893490/ so in lay terms "setting up the conditions for disease" as the gut microbiome includes the immune system. While bad enough already, there's more: https://pubmed.ncbi.nlm.nih.gov/29294235/ which mentions "The declared active ingredient glyphosate does not only inhibit the EPSPS but is also a chelating agent that binds macro- and micronutrients, essential for many plant processes and pathogen resistance". IOW even glyphosate-resistant crops can be (in practice always are) deficient in vital nutrients - like trace elements. That has been documented too: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4392553/

I read an article about olive oil and it's polyphenols and they mentioned a particular strain of olive trees that were the most drought resistant and found in Morocco and it's olive oil had the highest level of polyphenols of all that they had studied. So maybe if I get plenty of polyphenols in my diet I can become drought resistant too.
 
I did all of them except conceiving a child. I must be a failure.
Not to rub salt on your wound, but from a Darwinist/evolution point of view, it is.

Not only did I lose almost 60 pounds (and counting), but my triglycerides and blood sugar were slashed by more than half. I lost ten inches on my waist. Four months ago my doctor said to me "You are no longer diabetic." I am also no longer in danger of sudden death. And about a month ago I was finally approved for surgery that I've needed for years, and am scheduled for December 5.
Your decision, but given the impressive results, and proven strength of will and determination, do you still NEED that surgery?

I see you already won the war, why keep fighting in new fronts?

Joys of the Marketing department 🙄

Carefully designed ad, from half showing a guy who may be thought of as a Doctor (without expressly saying so) to the strength associated name "Fortior" to irrelevant but "healthy sounding" info such as "it is gluten free" 🙄

It is plain old Ethyl Alcohol, and derived from sugarcane, not grain.

Coming from none less than Mega Corporation Cargill, go figure.

Oh well.

My source of complete protein (IOW containing all essential amino acids), w-3 fat and antioxidants (among which polyphenols) is chia seeds, and consumption won't produce drought resistance. Just a good physical condition to the extent that those noticing it, immediately add the seeds to their diet, without asking questions. Well documented too.

Cargill is a name coming up in quite some documentaries on large scale irregularities in underdeveloped countries.

Just like Monsanto but these became masters in the disappearing act.
What matters is how it acts. Agriculture can be sustainable to a large extent (adding what is removed via harvesting), implying a healthy soil microbiome whereas herbicides do the contrary: destroying the soil microbiome, requiring much fertilizer. That can even result in the soil becoming unable to grow anything. Has happened here with a coffee plantation. Monsanto OTOH is notorious, notice the date of the article:

There was a documentary about how they destroyed the native corn species in Peru by introducing DNA manipulated Roundup resistant corn.

Everything one reads about this company is worse than horror. Like any large scale US company they have/had an army of the best lawyers. When things were about to go wrong for them they found an easy solution. The company was sold and the new owner is not liable.

I had to lose the weight to even qualify for the surgery. I have a umbilical hernia that is as big as a grapefruit, and is very debilitating. I can't over exert myself or lift more than 20 pounds. I can't hide it under clothes. It's holding me back big time and could become life threatening at any time.

Believe me, I wouldn't go through with this if I didn't have to. I already had hernia surgery 20 years ago and it is very unpleasant.

I remember reading how they tried to sue farmers that had their GM corn growing on their property, even though they didn't plant it. Eventually all the sustainable legacy corn was tainted by their GM corn and farmer's hands were tied. So Monsanto actually destroyed the local farming community with their invasive GM corn.

Lawyers decide everything now. They write all corporate policy. My last real job had a whole floor of nothing but lawyers. Everything had to be vetted by them.
 
The manufacturers all went to a Slim4 supply chain management approach where parts and supplies are forecasted to arrive right when you need them.
This means there is nothing just sitting on shelves anymore. It is supposed to be a great optimization. Apparently it all worked great until it didn't work anymore.

I know this is off topic but the nutrition parts of this are very interesting.
This is a link to the oil that I mentioned. https://gundrymd.com/food/olive-oil/
If you have any interest in heart health and longevity, check Dr. Steven Gundry's work. He has absolutely fascinating observations from his work as a heart surgeon. His story of a patient whose coronary arteries were too clogged to even be considered for surgery that had reversed his own condition by diet alone is amazing and gives hope to people who want to improve their health.

It was in the news that the more or less founder of this JIT system (Toyota) went back to classic way of purchasing and stocking of parts 😉

This thread is wonderful with intermixing subjects. It is like watching a soap with suspense, health and age issues, food, olive trees, oil extraction, quarreling, chit chat and even on topic items. I read every post but Fast Eddie D is standing out. Yes I am guilty too (as usual).
