sjducb··on Ugandan runner due to arrive in London after 516 days, 7,700 miles on the road
That is based on 2 studies, one of which puts the US as one of the least racist countries and the other puts the US as among the most racist. Something is wrong.

The US is very racist by self reported observation of racism. However citizens of different countries have different definitions of racism.

If you use a constant definition of racism like “Would you live next to people of another race, yes/no?” Then you find that almost all Americans say yes (low racism) . In some other countries over 70% of people would not live next to a person of another race.

Regarding China, Russia and India. They’ve all got a big problem with the literal enslavement of people from ethnic minority communities. I think that’s racism.

Canada and New Zealand are part of the “west” so they’re very similar to the US.

Jamaica is a good pick. A non western country that has very low levels of racism.

Maybe the assertion should be that the US is amongst the least racist countries in the world. The US is clearly in a different league compared to Russia, China and India.

Name a country that is less racist.

South Africa is a very racist country. You’re not really replying to my comment please re read it.

It’s racism. I’m guessing you’re from the US, the least racist country in the world.

People see he’s a different race so they treat him badly because of it. No one is worried about being called racist.

He was arrested several times a day for being black. No one in the whole chain of events viewed this as a problem.

sjducb··on What is metformin's secret sauce?
Mostly enormous libraries of compounds.

You take a cell culture model for the disease and see if the compounds affect the cells.

Then try it in animals, then humans.

Repeat this process until you have good safe drugs for all of the diseases.

sjducb··on Microsoft Confirms Password Deletion for 1B Users
It’s theatre because you still need the non passkey recovery method. The system is as weak as its weakest link.
sjducb··on Something weird is happening with LLMs and chess
Interesting thought the LLM isn’t trying to win, it’s trying to produce data like the input data. It’s quite rare for a very strong player to play a very weak one. If you feed it lots of weak moves it’ll best replicate the training data by following with weak moves.

100% Always measure before you performance optimise. Lots of times the “fast” solution is slower.

If you need a fast solution then add an integration test so that the system stays fast.

The limbic system is a neural net that’s been training for a billion years. It’s probably right.
sjducb··on Write code that is easy to delete, not easy to extend (2016)
It’s so easy to accidentally write an ORM or a database. I constantly stop and think; is this piece of code secretly a database?

Tests are great, but there’s more to programming than writing tests. People don’t have to mention tests in every article.
sjducb··on Ion engines could take us to the solar gravitational lens in less than 13 years
Another way to get a spacecraft to 550AU would be to use solar sails and ground based lasers.

You have a small spacecraft (USB memory stick sized). Do a sub-orbital launch to get it out of the atmosphere. Then deploy the solar sails and fire ground based lasers at the craft to accelerate it. IIRC the theoretical maximum acceleration gets a you to 550AU in a few months.

sjducb··on Monorepos vs. many repos: is there a good answer?
I find it easier to work in companies with monorepos. It’s much easier to grep for what you’re looking for. There’s no complexity hiding somewhere you don’t know about.

Whenever I work somewhere with lots of repos I create a folder called dev and clone every single repo into it.

sjducb··on Ask HN: How to store and share passwords in a company?
I think stack exchange would delete the question because it is too vague and open to opinion.
sjducb··on Have supermarkets reached peak self-scan?
Ever considered

Do you want a receipt? No Cancel Sale Remove cash from drawer later.

There are so many ways a person can steal from the till.

sjducb··on Have supermarkets reached peak self-scan?
The main reason for the growth of self scan was loss control (theft reduction). Most theft from stores is by staff not customers. Removing the human from the till reduced the theft. This worked for several years, until customers worked out how easy it was to steal from self service checkouts. Now self checkouts don’t have the loss reduction benefit they are being phased out.
sjducb··on Parochialism in time and space (2021)
But views and norms are shared within a country and you can make accurate predictions about people based on their race, country of birth and country where they grew up.

- A white person from Sweden is likely to be pro choice by American standards. (95% chance. https://en.m.wikipedia.org/wiki/Abortion_in_Sweden#:~:text=A.... )

- An Egyptian is likely to think that FGM is normal and a good thing. (Over 85% https://egypt.unfpa.org/en/topics/female-genital-mutilation-.... )

- A Lebanese person will probably have antisemitic views (Over 85% chance https://global100.adl.org/country/lebanon/2014)

I recently went to a wedding. Who got drunk and started a fight? Was it the only Irishman?

I would predict that a white British person thinks that gun ownership should be restricted to military and police. A Swiss person will think that everyone should be given a rifle by the government. (Over 95 percent of Swiss households have a fully automatic rifle)

You can group people by ethnicity and nationality, then observe big differences between the groups.

Elites in Kiev had all kinds of fancy stuff. They’re not the ones working for 30% of a western developers wage.

The hard part of software is the communication. The easy part is writing the code.

Outsourcing makes the hard part harder.

If you completely misunderstood what your manager wanted, would your productivity be 80% or close to 0?

You are underestimating how difficult it is to communicate with people from different cultures.

I did an electricity project with developers from the Ukraine. We spent a week being confused because the Ukrainiens expected the electricity bill to be calculated based on the size of your house and how many animals you have. The concept of a domestic electricity meter was completely foreign to them.

I also worked with a Ukrainian graphic designer who had no understanding of copyright law.

sjducb··on Waymo to begin testing on San Francisco freeways this week
Emergency braking is much harder at freeway speeds.

At 35mph you can have something (radar/cameras) look a few meters ahead, then if there is a stationary obstacle you slam on the brakes.

At 60 that doesn’t work because braking distances are much longer. There might be an obstacle directly ahead of you on the pavement, but you won’t hit it because the car will turn with the road. This means that your emergency braking system needs to be aware of the steering, the road layout, and the expected route.

sjducb··on A primer on the current state of longevity research
Yes our modern world does not make good use of grandparents. Given enough time you might expect that the cost of carrying elderly relatives is enough to select for quick dying grandparents. It might also select for healthy long lived grandparents who are not a burden. Probably both will be selected for in parallel .

Grandparents contribute to the survival of their grandchildren. Evolution has selected for long lived grandparents. The same thing happened in elephants and whales.
