sveng··on How a Gas Compressor Station Works
Interstate or longer intrastate pipelines require compressor stations every 75-100 miles. The parent article mentions this under "Compressors". As another comment states, friction is the main reason.

sveng··on Ask HN: Favorite Podcast Episode of 2021?
This doctor's claims made on that podcast have been largely debunked.[0] And his association with a serious-sounding medical group is rather revealing.[1]

JRE as Entertainment? Yes. Accurate guidance on important science issues? Not so much.[2]

sveng··on The Most Influential 80-Plus-Year-Olds in America
When he addressed this first (early March) there weren’t enough masks for HCWs. It was superseded by a CDC directive in early April. [1]

sveng··on Gates Foundation will commit 'total attention' to coronavirus pandemic
Since its inception, the Gates Foundation has made total grant payments in excess of $50 billion.

I’d say that deserves attention.

sveng··on Ask HN: I want to resign with nothing lined up
I’d take a few days off if you have any, and take a long weekend to ponder a few facts (some other comments have raised these):

1. Maybe I’m a bit burned out and need a break.

2. Or maybe I’ve got a health condition that I should check out. Talking this over with a doctor or therapist could help.

3. Everyone is stressed and fatigued now. It’s the only new normal.

4. Covid-19 will likely flare up again this winter. And a vaccine, if one is developed next year, will take most of the rest of 2021 to roll out. Or longer.

5. More companies will go out of business and more employees will be shed during that period. Some of both may be potential customers of your “project.”

6. Try to search for another job before you bail. Thinking about how you can sell yourself is a good exercise.

7. Interview for a few positions, carefully.

8. If you can’t find any good jobs, stay where you are.

9. Start working on your project now and see if it’s got real business potential or is just a pipe dream.

10. If you really have no project, and it’s a pipe dream, stay where you are.

11. Talk your situation over with a mentor or an older friend. If you have neither, stay where you are and find a mentor.

12. Face the reality that two years out of uni is nothing. In the sense of a career.

13. Face the reality that soon you will appreciate your job more when you see how many people don’t have what you have. Don’t feel guilty about not feeling that way now.

14. Your runway metrics are insufficient in the Covid-19 era. I’m not sure you’re paying enough attention to the economic consequences of the pandemic.

15. Be more discreet on public forums; you are over-sharing at least 3 key facts.

16. Be wary of taking advice from strangers, including me.

17. “Do it” Is not advice, it’s a remark.

Good luck, take care, and remember your country voted years ago to leave the EU, and your PM who is supposed to lead your county through that maze was hours away from being put on a ventilator a week ago.

It never hurts to take advice from Ferris Bueller, though.[1]

sveng··on The plans to reopen the economy are scary
It’s going to take a while to unpack your comment.

Until then, while you mention Ro, you might not know that some recent reports show it approaching 6 in some areas, not 2.x as thought by some over a month ago. With an Ro of 2.5 and a mean infection duration of 5 days, each person can cause infection of up to 244 cases in a month.

Also, since testing is not widely and reliably available in most countries, there is no way to loosen stay-at-home as a practical matter. Pervasive testing, quick contact tracing, isolation and quarantine are the only way forward.

And I’m not sure you are factoring in that Covid-19 positive people can be contagious before they show ANY symptoms.

So if you’re not concerned about older people or people with comorbidities generally, you might look around at the people you know and care about.

The other part of this is the impact on health care providers and first responders. They are getting infected and dying. The have more pressing issues than those you mention.

I find thinking about my community and taking certain matters of personal responsibility seriously helps me dwell less on myself.

Good luck...

sveng··on 50% – 75% of cases of Covid-19 are asymptomatic
aka Tylenol (acetaminophen) in the USA. Consult your doctor. Not sure what this means for children, but this directive against NSAIDs is a really important development in treatment protocols for COVID-19.

sveng··on Google Cloud Next 2020 – in person event cancelled
I don’t think they’ve fully faced the emerging danger of COVID-19 for an event like this. It’s not just the 400,000 attendees, it’s the 2.2 million people in greater Austin.

COVID-19 can render a victim contagious within 12-24 hours after contact. That person can be asymptomatic for 5-7 days, even longer.

Attendees either start to get sick near the end, or on the trip back home. Or bring it to home and their workplace.

There are no vaccines, no one has any immunity. It is NOT the flu.

I’d bet it will be cancelled, when the promoters realize how many people have bailed already and the massive public health risk it poses.

In Italy they are playing soccer games to empty stadiums.

sveng··on WHO: COVID-19 in 29 countries last Monday, now 56
I’ve seen reports of 80% mild, 15% hospital (mainly oxygen and managing secondary infections) and 5% critical care (ICU, some intubations). But, yes, even 5% could overrun hospital resources.
sveng··on WHO: COVID-19 in 29 countries last Monday, now 56
Experts say a vaccine is 12-18 months away for wide use. Then the task of manufacturing a billion or so for starters.
sveng··on World Economy Shudders as Coronavirus Threatens Global Supply Chains
I’ve seen C19 rates of 20% seriously ill (hospitalization) and 5% critical care (ICU). Almost no country has the capability for this, even in large cities.

There are vaccines for flu; none for C19 for 18 months at the earliest. Also, C19 is contagious when victims are asymptomatic. It aerosolizes so it can spread across rooms and potentially through ventilation systems.

Many C19 healthcare workers are becoming infected, some dying. This is unheard of with the flu.

And C19 is uncontained, unlike SARS. It meets the definition of pandemic now (2+ continents and community spread). The WHO will finally recognize this any day now.

To equate C19 with the flu is inaccurate and dangerous.

Watch this video from CNBC last Friday.[1] It’s excellent, and features experts who do not mince words.

sveng··on Fogg Behavior Model
Atomic Habits is interesting.

Tiny Habits is great. It is deep while being approachable. BJ Fogg is not only a serious researcher, but also a superb teacher.

Tiny Habits is a book to buy, to read, and to apply to your life (both personal and professional).

If you are serious about improvement, it is essential.

sveng··on Luhmann's Zettelkasten
That is interesting; here’s another from Ryan Holiday that goes deeper:

sveng··on Interpol issues 'red notice' for Carlos Ghosn's arrest
It’s a wild story if this article is to be believed:

https://nypost.com/2019/12/31/ex-nissan-honcho-carlos-ghosan...

(Hiding in a musicians’ case; used by musicians who really weren’t).

Surely this will be made into a movie or even a series.

sveng··on Zen and the Art of Software Maintenance
I agree with you, it’s a fantastic book, and not really about motorcycles at all.

(If memory serves, Pirsig used note cards or slips of paper to assemble this ambitious work. Post-It’s were first sold in 1977; the book was published in 1974.)

Those who have an open mind and want to try the book should find the 10th anniversary edition; the author’s afterword explains some things that some readers found elusive.

Pirsig’s obituary in the N.Y. Times is excellent:

sveng··on NASA Will Open Pristine, Sealed Samples of Moon Rock
The article and interview with one of the lead researchers mentions the 50th anniversary of the first landing. And also how analysis of these final sealed samples could guide potential landing site targeting for future missions.
sveng··on Ask HN: Client replaced me with offshore team – what could I have done?
They have the money. Don’t lower your prices. Keep looking for new clients even when busy. I can almost guarantee that the offshore solution will cost them more in the long run.

It’s a sign that the finance people are running the show. I’ve seen that movie, and it rarely ends well.

sveng··on The making of Amazon Prime, the internet's most devastating membership program
Not sure if you actually read this article. It’s excellent, especially its narrative stitched together with first-person, you-are-there, accounts.

Rather timely also since Amazon announced this week that it’s working on one day deliveries for Prime customers.

And those in the know will tell you that same-day (even 2-4 hours!) deliveries are on the roadmap for Prime customers in major metro areas.

sveng··on Ask HN: One-person SaaS apps that are profitable?
The last two sentences that comment are meaningful to me.
sveng··on Boeing delays 737 MAX software fix delivery
No, not mismanagement. Here’s my opinion:

There’s about 40 seconds before the aircraft becomes unrecoverable in these 2 crash scenarios. It’s not pilot error.

It’s design, software, certification subterfuge, lax FAA regulatory posture, and limited pilot awareness and superficial training. Roughly in that order.

Add to that desperation, in that Boeing was keen to catch up with the Airbus 320neo, and didn’t want to build (and certify) an entirely new aircraft.

Plus an extra sensor and related systems most US 737MAX’s have was an option, and at least the Lion Air aircraft didn’t have it.

Demonizing pilots or belittling the training of the LionAir and Ethiopian Air pilots is offensive and not supported by the facts.

This is going to get worse for Boeing. Their only saving grace is that the airlines and military need them too much.

sveng··on Postcards That Captured America’s Love for the Open Road
It’s actually amazing (both); when you walk out to the tip of the Horseshoe Falls, you are at the end of the road.
sveng··on Ask HN: How did you find your passion?
Finding your passion is a bit of a trap; this article explains some reasons why:

https://mashable.com/2017/03/22/7-habits-you-need-instead-of...

Some of the history of “passion primacy” is based on the Hedgehog Concept of Jim Collins in his book Good to Great:

https://www.jimcollins.com/concepts/the-hedgehog-concept.htm...

Mr. Collins was talking about great companies, however. But his three criteria are instructive.

Put another way: passion finds you. And it probably won’t if you’re thinking too much about it.

sveng··on Ray Dalio AMA
Mr Dalio wrote the book because he is interested in optimizing business results, and learning how people work together best and why.

If you’ve started a business, or manage people in a business, this book is worth more than many MBA courses.

The fact that a person with his exceptional track record decided to share much of the Bridgewater “secret sauce” is rare, and a real treat.

sveng··on How to Come Up with Profitable Business Ideas
Plain text passwords are a poor security practice, not fraud per se.

There’s no sense it was intentional, nor that any customers were impacted.

I used the Adobe example since 38 million customers had personal information exfiltrated in 2013 (including me).

Adobe knew better (or should have). But that still is not fraud.

They have enhanced their security practices since then, and I am still a customer of theirs.

sveng··on How to Come Up with Profitable Business Ideas
I read this story exactly the opposite: it doesn’t have to be perfect at the start. You just build something people want, and then hire a team to improve the back end (without destroying what people wanted it for in the first place).

Major companies have had security issues (such as Adobe) but that doesn’t make them a fraud.
