geomark··on The lesser-known Orwell: are his novels deserving of reappraisal?
I'm not even talking about hate speech/incitement. I'm talking about the whole year's haggling over so-called fake news whenever there were opinions that did not match the official narrative. For example, if there was an opinion posted that contradicted the WHO or CDC on Covid then it was flagged, despite in some cases the obvious dissonance like the "masks don't work but they should be reserved for health workers" guideline.

The preface to Animal Farm is pretty interesting in how it paralells the current social media censorship with the censorship imposed by the English intelligentsia of Orwell's day.

Southeast Asia is pretty diverse. What you said about last mile fulfillment isn't at all true in Thailand. Postal mail is reliable all over the country and there are multiple other fast and reliable delivery services.

geomark··on Ask HN: Please share your experience teaching your kids to program
Oh yeah, that. This is a book so you don't have a lot of that shady stuff. But you do need to download and install their server code so you can run a Minecraft 1.12 server on localhost. Seems safe and no malware.
geomark··on Groundhog: Addressing the Threat That R Poses to Reproducible Research
Back when I studied this stuff there was a distinction between reproducible (rerun analysis on the data from the original experiment and see if you get the same results - if not then there is an error in the analysis) and replicable (redo the entire experiment by taking new data and running the analisys).

Have you seen the book "Adventures in Minecraft [1]? Modding Minecraft with Python. I'm working through it with my 10 year old at the moment. Pretty good so far. Nothing "shady" (not sure what you meant by that) and not complicated.

geomark··on Getting Started in Robotics
As the author says "... it’s tough to hack together a demo in a few weeks, get users, and bootstrap / apply to some accelerator like in many software projects". So the financial rewards don't seem to be there in robotics startups. And as a result it seems that engineers in the field aren't paid that well compared to software developers, despite it being highly technical and requiring a rather vast skillset. Will that ever change (the financial part)?
geomark··on My Experience at Apple
Point number 1 is very important to never forget. No matter what level you are at, HR's job is to protect the levels above you, not help you. If you are an engineer that means an opaque shield of HR policies to protect the company and all people in your management chain. Middle manager? HR will shield the directors and VPs above you, concentrating particularly on keeping the VPs safe no matter what they do.
geomark··on Bitcoin is a collectors items
"21 million is a big finite when it comes to collectibles"

It's worse than that. You can divide BTC into a lot of tiny pieces. So there are lot more than 21 million pieces. Most collectibles are valuble as the whole thing, not little pieces sliced off of them.

geomark··on Ask HN: Why does Pinterest dominate Google text search results?
I use that a lot. Wouldn't Google notice if a lot of people were telling it they don't want to see results from Pinterest and make some adjustments to their SERPs?
geomark··on Tibor Gánti's ideas about the origins of life
Metabolism has two parts: Catabolism breaks down complex molecules into smaller building block molecules - think proteins -> amino acids. Then anabolism uses those building blocks to build up larger molecules for growth and maintenance. Crystals don't do the catabolism part.

Unless it happens in your attitude control system or your command and control system, causing you to lose control of or communication with your spacecraft.

Since you have recently been through this, what were the other available options? There were a couple other rad hard processors under development years ago when I left the industry. Do you know what happened to those?

Polyethylene is usually used to shield against cosmic rays. Nearly identical shielding performance as water. Slightly less weight per volume. Can be formed easily and retains its shape.
geomark··on A New Satellite Can Peer Inside Buildings, Day or Night
ICEYE's website says high res (25cm) imaging is commercially available. Even has some sample 25cm res images available for download at the bottom of this page (I have not downloaded so can't vouch for it) https://www.iceye.com/satellite-data/blog/new-benchmark-in-i...
geomark··on A New Satellite Can Peer Inside Buildings, Day or Night
Well yes, it's the surface disturbance of the underwater wake that they are detecting. So the sub has to be moving under its own power.

But there is no need for high resolution and the wake of the sub stands out starkly even with a large field of view. So I'm not sure it can evade detection by halting propulsion and drifting. The point at which it halted would be known and it would be detected as soon as it restarted, unless it was carried by an unknown current far enough to be out of view of the satellite.

That's right. The article says "...other SAR satellites on the market can only get down to around five meters" which isn't true if the story I linked is accurate.

Article says they are by law limited to 50cm resolution. But there was another SAR satellite launched in March 2020 that claims 25cm resolution.[1]

Also used to track submerged submarines by detecting ocean surface disturbances caused by the underwater wake of the submarine. Same benefits: works at night and through cloud cover.

Not sure why your mate's manager had a problem with passive voice. Passive voice is often the correct choice in documentation. Passive voice emphasizes the doing, not the doer. People usually don't care about who did the doing in technical documents.
geomark··on First person receives Pfizer Covid-19 vaccine in UK
That's what is happening at this moment in Thailand. There were no local transmissions for many months. Borders are closed and anyone coming into the country has to go directly to 14 day quarantine and test clean before they get out. But then some Thais went to Myanmar and snuck back into Chiang Mai in northern Thailand illegally. They were infected and have now spread the infection locally in Thailand to at least a few people. Some cases took flights to Bangkok. There is a frantic effort to track and trace everyone who might have been exposed.
geomark··on Photonic Quantum Advantage?
Correct. It doesn't have to be fake. It could be a very real breakthrough. Then the possibilities branch out. Taking the next step might require huge resources. Will the enemy take that on? If so, can you just watch and spy, saving your own resources to apply to other or more promising efforts?

Some people might think this is all just being too imaginative. But that is what the spooks are constantly doing, creating layer upon layer of misdirection and obfuscation. To wit, a sibling comment[1] about the Star Wars program.

geomark··on Photonic Quantum Advantage?
Or maybe it's a misdirection to get the enemy to go down a path they know is a deadend.

Or a lure to get the enemy to work harder on a problem so they can steal the solution.

Or fake so that the enemy spends more resources faster.

Or any of many other possible scenarios. It's a nonstop game of spy versus spy.

geomark··on Face masks considerably reduce Covid-19 cases in Germany
And Thailand and Taiwan (I think) and maybe a few other countries. I think that is certainly a factor.

But something seemed to change, at least here in Thailand. Although mask wearing was normalized in cities as self-protection against air pollution, many/most people seemed to come around to the notion that mask-wearing was a collective effort to mitigate the spread of the virus. Seems like a cultural effect - more collectivist rather than individualist thinking.

geomark··on Face masks considerably reduce Covid-19 cases in Germany
Yes, you're right of course. "The west" is a big place with many different moving parts, just like Asia. So things aren't the same everywhere. It's just that there are many western countries where the arguments about mask wearing and social distancing are still going on while the pandemic is raging while in most of Asia that isn't happening and the pandemic has largely been nipped in the bud.
geomark··on Face masks considerably reduce Covid-19 cases in Germany
Are people still confused that the reason you wear a mask is not to protect yourself directly, but to protect others thereby indirectly protecting yourself? It seems so, because in the west people are still arguing about wearing masks, and doing these inane studies, while in Asia people wear masks and go about their business as usual.
geomark··on Vitamin D insufficiency may account for almost 90% of Covid-19 deaths
Your comment reminded me of this Dilbert https://dilbert.com/strip/2014-05-09
geomark··on Vitamin D insufficiency may account for almost 90% of Covid-19 deaths
Asia is a big place. In some densely populated areas in Asia most people live in bubbles, moving from air conditioned condos to taxis/subways to offices and then malls. They spend as little time as possible in the open due to pollution, weather and a cultural aversion to tanning. As a result, vitamin D deficiency is very common.

Some examples for Thailand are included in this paper[1]. One study said this: "Soontrapa et al. [15] evaluated vitamin D status in a younger group of premenopausal women found the prevalence of vitamin D insufficiency to be 77.8%, which was as high as the rate found in elderly Thai women living in nursing homes."

There is lots of sun in Thailand, but people avoid it as much as possible, staying indoors and applying lots of sunscreen if they must go out.
