dudeofea··on Documentary spurs a new look at the case of the first gene-edited babies
man-made horrors beyond your comprehension, that's how.
dudeofea··on Many women struggle to breastfeed. Scientists are starting to ask why
we're more chronically stressed now, which is the stress we are less adapted to. acute stress (followed by relaxation) is not only better than chronic stress, its better than no stress at all.
dudeofea··on Do we live in a society without a counterculture?
If you're interested in a more nuanced view of hippies, read "Jester: Memoirs of a Retired Hippie"

No one is objectively good because they are human after all. Hippies had good values, but also bad ones such as: uncleanliness, irresponsible drug use, parasitism, thoughtlessness, and sometimes even vanity.

dudeofea··on Ask HN: Is programming culture immature?
I know electrical engineers that spend their whole day picking out doors for hydro-electric facilities and chemical engineers whose job is to sell various pipe valves.

The programmer equivalent might be refactoring variable names to "int i_FallDistance_mm" or working in crypto.

If you aren't sure if your current job is one that an engineer would do, you could consult the engineer code of ethics. Broadly:

1. shall, in their areas of practice, hold paramount the health, safety and welfare of the public and have regard for the environment.

2. shall undertake only work that they are competent to perform by virtue of their training and experience.

3. shall conduct themselves with integrity, honesty, fairness, and objectivity in their professional activities.

4. shall comply with applicable statutes, regulations, and bylaws in their professional practices.

5. shall uphold and enhance the honour, dignity, and reputation of their professions and, thus, the ability of the professions to serve the public interest

dudeofea··on ‘Luddite’ Teens
if what you are saying is that any deviation from the norm incurs a cost to your life, I agree. Some people are already abnormal so they can't pay that cost, but others can't pay simply because of some of the other choices they have made. I personally wouldn't call the latter a lack of privilege

Firefly was a mistake,

in that the corporate machine made a mistake in not extracting all that it could from it in follow-up seasons, movies, sequels, etc.

You know how good a movie is by how many sequels it took to kill it.

dudeofea··on US Covid death toll would be 4X higher without vaccines, modeling study finds
Most people don't choose to be obese

Obesity was rare a few decades ago

Marketing and cheap price are the transmission vectors

Both of which could be curtailed if the government chose

PUFAs don't have to be cheap, just like cigarettes are not cheap by choice

dudeofea··on Automation enables founders to grow companies with fewer and fewer employees
I can't speak to the second half of what you said, but for the first half: The jump is not as big as you think for any competent piece of automation.

Using your example of a blacksmith upgraded to machine shop worker, then later upgraded to robotic machine shop worker. In the first upgrade, the blacksmith no longer needs to hammer iron as this is done by a drop press. The skill lost (big arms for hammering) is replaced by a many fold increase in productivity and a removal of many people alternating hammering.

In the second upgrade, using robots for production, you do need to learn some programming, but the programming is centered on such industrial applications. In modern cobots you don't need 3D math or almost any programming knowledge. You just need to give it a set of steps to follow and you can lead it by hand https://www.youtube.com/watch?v=9iCLK__7ymY

As with most automation, the initial prototype is more cumbersome to use, but eventually it becomes a tool like any other.

dudeofea··on Lab-Grown Meat Is Safe to Eat, FDA Says
I agree. Lab grown meat seems like a further step towards the preexisting industrialization of meat.

Removing the sentience from cows does reduce animal suffering, though I wonder if other things couldn't be done to preserve genetic diversity. Like maybe breeding oysters without ganglia, as they are barely alive to begin with. Farmed oysters are also better for the environment than wild ones.

dudeofea··on Lab-Grown Meat Is Safe to Eat, FDA Says
The source of potato blight is from the genetic similarity of the potatoes grown, as potatoes clone themselves when grown from potato seed (small potatoes) rather than "true" potato seeds, from their flowers. They are naturally selected, then naturally cloned en masse.

Lab grown meat will have the same problem assuming the cells have little to no genetic diversity. Even if grown in a sterile environment, they could become susceptible to a blight-like organism (virus, bacteria, fungus, etc) once on grocery store shelves.

dudeofea··on Lab-Grown Meat Is Safe to Eat, FDA Says
does that include bioavailability of those calories to humans?

from this anecdotal source: https://www.reddit.com/r/explainlikeimfive/comments/sbfn6b/c...

1lb of grass to humans = 32kcals / lb

1lb of grass to cows = 800kcals / lb

800/32 = 25x

Assuming you grow something other than grass on that pasture to eat (also assuming it isn't marginal land which makes up 2/3 of agricultural land), wouldn't that other plant extract approximately the same amount of calories from the sun? And wouldn't the bioavailability of that plant also be lesser than that of meat?

dudeofea··on Lab-Grown Meat Is Safe to Eat, FDA Says
If it was evolutionarily optimized, it most likely is not the most efficient way of doing something but it most certainly is the most resilient way.

Potato blight? soon to be available for: meat!

dudeofea··on Myocarditis after Covid vaccination: Research on possible long-term risks begins
catching covid always involves an infection of a respiratory tract (nose, mouth, etc) but not necessarily an infection in the bloodstream

covid vaccines are always present in the bloodstream after injection, even if injected intra-muscularly

an early study in japan showed only ~25% of the vaccine stays at the injection site

how is it a nightmare? if you aren't getting that energy from natural gas, you'd mostly get it from a CO2 producing power plant, with efficiency losses going from heat (steam) -> electric -> heat (cooktop)
dudeofea··on An “Extreme Heat Belt” will soon emerge in the U.S.
"When Hausfather's team set pollution inputs in Hansen's model to correspond to actual historical levels, its projected temperature increases lined up with observed temperatures."
dudeofea··on Postmortem assessment of olfactory tissue degeneration in patients with Covid-19
Caveats: study is pre-omicron, and in a population that has a higher likelyhood of previous infection (nurses). Infection followed by vaccination leads to supposed "hybrid-immunity". These findings may not translate to those who did not get infected but were vaccinated
dudeofea··on Why DC May Replace AC (2019)
I'm not sure if that's the moral of that video. Just watched (had seen before), and his conclusion is that you shouldn't transmit power with low voltage because it means you need lots of current.

HVDC has some tradeoffs over HVAC, but you should be able to transmit power just fine with either.

HVDC doesn't suffer from the skin effect that AC does: https://www.allaboutcircuits.com/textbook/alternating-curren...

HVDC is however harder to make/break contact with compared to HVAC as AC crosses zero volts many times: https://electronics.stackexchange.com/a/325608

dudeofea··on Covid Policy Killed My Grandmother
Also in Ontario: https://www.cbc.ca/news/politics/long-term-care-pandemic-cov...

>> Several of the assessments noted unsafe conditions that could help spread COVID-19, including instances where patients who had tested positive for the virus "were allowed to wander" and staff members left with inadequate personal protective equipment.

Personally, I believe the virus would have spread regardless of the isolation techniques used (and can be demonstrated to have in other places with stricter policies).

Regardless, why the residents themselves weren't in charge of the policy on lockdowns is stupid in my opinion.

dudeofea··on Ask HN: I just gave myself a panic attack. How do I stop this?
having had a few hundred, I usually characterized mine as having the following timeline:

1. A few seconds of acute fear

2. 10 to 30 minutes of anxiety

3. An hour or two of cooldown before return to normal (initially it just drained all my energy and made me depressed)

I'm a naturally anxious person, but that's okay. here are some things that help in phase 1:

- Spot 5 things you see, 4 things you hear, 3 things you touch, 2 things you smell, 1 thing you taste

- Try to think logically about what it is you are anxious about. I had medical anxiety and would convince myself of delusions of having possibly contracted tetanus from a finger prick while restringing my guitar. After some research, the logical conclusion was that tetanus is most commonly found on farmer's fields not metal, presents in deep wounds and has an incubation of 10 days on average, so no point worrying now. It's also curable.

- If all else fails, just remember phase 2 will soon be around the corner

For phase 2, remember that your emotions and your thoughts are most likely at odds. if you can integrate what your emotions feel into what your thoughts think, you may still have panic attacks but they shouldn't ruin your day. This is where the CBT that others mentioned is relevant. I sparsely went to therapy so didn't know this initially. Many times with my panic attacks I felt as though there was a question that needed answering and once I found the answer I would have to write it down because afterwards I felt that the answer no longer mattered enough to remember. This happened many times as I believe I was piecing my life together one anxiety at a time. I think I didn't remember it because it became a part of me.

For phase 3, have some snacks and try to get your energy back.

Another important part of CBT is asking yourself the question: what would I be doing now if I was living a worthwhile life?

and then doing that no matter how much it feels wrong.

EDIT: I rarely go to therapy and am not big on drugs of any kind (even alcohol, tylenol, caffeine). What did help for me which I don't necessarily recommend is a keto diet. I now fast until ~2pm each day and I find I get similar albeit less pronounced benefits.

dudeofea··on Why I’m for Covid vaccines, but against vaccine mandates
unlike many public health authorities, grujicd is forming a hypothesis and showing a method to attempt to prove said hypothesis. If you don't like it, you can suggest your own.

In this way, a reader can deduce what they believe is the closest truth available rather than it be shouted down at them. The fact that grujicd did not interpret Gibraltar data accurately is, I believe in this case, not a mark against them but a testament to how well they formulated their argument that flaws can be evaluated easily.

public health authorities on the other hand will begrudgingly hand over data after months of outcry, as well as change testing criteria and engage in many other methods of purposeful/accidental obfuscation, making their arguments hard to decipher.

less oven space, need to replace entire stove, made in a factory and not at home.

It is cleaner perhaps and more purpose-built. But I would not call that practical.

You could try coppiced trees: https://www.lowtechmagazine.com/2020/09/how-to-make-biomass-...

They grow faster since they already have a root structure, the size is consistent and the wood is generally straigter (the japanese have a similar technique for extremely straight cedar logs)

dudeofea··on SARS-CoV-2 variant A.30 is heavily mutated and evades vaccine-induced antibodies
Dengue. The initial vaccine did not target all subtypes of dengue, causing "severe dengue" in infections after a naive individual was vaccinated. The same could happen if someone moved from one region to another, since the subtypes inhabit different regions. Your body will respond to one subtype's antigens primarily with it's initial conditioning. If you weren't conditioned with that subtype, you get original antigenic sin / severe dengue

https://www.cdc.gov/dengue/prevention/dengue-vaccine.html

The worst-case scenario for a vaccine is not "no immunity", it is negative immunity. If your adaptive immune response outcompetes your innate immune response in binding to antigens, but does not neutralize them, then your immune system will struggle to fight off an infection

dudeofea··on Vaccinated Are Not ‘Just as Likely’ to Spread the Virus as Unvaccinated People
Here are some: https://archive.is/T23eV https://www.nature.com/articles/d41586-021-02187-1

I think it would help everyone if we all used specific terms when discussing covid infections.

From what I've gathered, the current generation of covid vaccines (mRNA, J&J, AZ) induce mainly a IgG immune response (as well as other things I know nothing about), but they certainly do not induce an IgA response. IgG is humoral immunity which protects your blood, and lower respiratory track somewhat, IgA is mucosal immunity which protects your upper-respiratory track (nose, mouth, etc) as well as other mucous membranes.

Since covid typically first infects the nose, studies which I cannot find at the moment have shown that vaccinated individuals have only slightly less viral load in the nose than unvaccinated. At the onset of the curve however (first few days), they are the same.

Viral load does not equate directly to infectivity, but from this we can say that vaccinated people can spread covid, whilst being asymptomatically infected.

Saying you "have" covid is too vague, since you can "have" it in your nose, in your blood, etc.

dudeofea··on You don’t need standups
Screw these other commenters saying you're a stubborn introvert. If I had a company, I would hire you. I have the same view.

Micro management erodes trust, which deskills programmers. If you know the exact bounds of what a programmer that you hired can do, then they can never do anything exceptional. I understand large companies need reliable workers because they are working on cornering their market, but for startups, or just for anyone going after something that's never been done, you need to take a risk, and that risk includes your programmers as well.

What's more, there's a small but important difference between being told to go to a meeting and converse with other employees, or CEOs, or clients to get some external validation on your work, and choosing to seek out those people of your own free will. I agree that no programmer can silo themselves off and "do work", but that doesn't mean we have to infantilize them and spoonfeed them their feedback.

A fisherman knows how to catch fish, so why are you telling him what lure to use and how to cast his line rather than just letting natural competition takes it's course and allowing him to become jealous of the better fisherman and having him improve. "Didn't catch a fish today" "well you should've used the red lures like Bob does". Do you want a better fisherman? or do you want the same fisherman?

dudeofea··on Ask HN: What simple tools or products are you most proud of making?
greate stuff! I feel that for things like this, the real problem to solve is getting it out to people, which might be why some programmers shy away from it. Though, I love stuff like this. Not everything needs to be disrupted by a pool of GPU-assisted tensorflow instances, low-tech is still way better than no-tech. Keep up the good work, and hmu if you need an extra hand
