lesam··on It’s time to leave the leap second in the past
Sundials are already ‘wrong’ according to solar time by 30 minutes or more, as an artifact of dividing the world into hour-wide time zones.

Astronomy already ignores leap seconds in the same way that modern finance ignores half-crowns and shillings.

lesam··on Leaked documents reveal Amazon’s process to review employees’ worth to Amazon
I hate that some people say rockstars and mean ‘really great developers that write beautiful working well documented code quickly and work great as part of a team’.

And other people say rockstars and mean ‘assholes that churn out new features really fast with incomprehensible code and then leave others to maintain their monstrosity as they move on to the next thing”.

I assume Amazon is large enough to have a team somewhere with 6-10 of the ‘good’ version, and also a team somewhere with 6-10 of the assholes.

lesam··on Stop saying “They shouldn't have invested more than they could afford to lose”
It’s not just bitcoin.

People are told to “invest for retirement” and to do their financial planning based on 4-8% per year growth after inflation, when the risk free rate has been 2% or less for 20 years.

If the US stock market stagnates for the next 20 years like it has in other countries, people will be blamed for buying ETF’s too. “Don’t invest money you can’t afford to lose”, say the people who profited from 20% annual growth on houses while mortgaged to the hilt. But also, “why can’t millennials afford houses?”

lesam··on The slow march of progress in programming language tooling
I’ve worked in C++ and picked my own tools. The tooling experience in Go is much more polished for a few reasons.

First, as the author states, it’s hard to get consensus on a tool if it wasn’t baked in from the beginning. I don’t think there will ever be a dependency manager or especially an option-free formatter for C++ with the same adoption as gofmt or go modules.

Second, it helps a lot to have the compiler/runtime authors think about the tooling. Go runtime developers think about pprof. GCC developers don’t think about the UX of valgrind. C++ standard authors don’t write PR’s for code formatting tools when they change the language spec.

lesam··on ‘Your Map Is Wrong’
My model is advertising is roughly zero sum - there’s only so much disposable income for advertisers to chase.

So it doesn’t seem contradictory that overall consumption stayed constant while the advertising arms race advanced significantly.

lesam··on Humans can't endure temperatures and humidities as high as previously thought
The study has a sample size of 25 young adults, presumably students at Penn State in Pennsylvania.

lesam··on Cancelling Student Debt Is Unforgivable
‘Not what it is about’ according to whom?

Most students are in school because they want jobs, not to learn to think. The professors may be interested in that goal but how can they possibly achieve it with a student body that just wants their degree papers and a shot at the upper middle class?

lesam··on Experts once predicted that Americans would face excess leisure time (2015)
Shelter costs have also increased massively, not only because shelter has gotten better but because there’s more room in people’s budget for landlords to capture.

Medical and educational costs have risen in the US, I would argue for the same reason.

And some adversarial work has expanded for no reason- look at all the effort spent in high frequency trading that could be replaced by venues running auctions every 100ms instead of having competitions for fractions of a microsecond.

lesam··on Experts once predicted that Americans would face excess leisure time (2015)
Humanity is much more productive per capita than 50 years ago, but we are collectively working more hours, not less.

The goal should not be for everyone to do no work.

The goal should not be for everyone to work full time and fear unemployment.

lesam··on Ask HN: Which programming games helped you become a better programmer?
I started programming with “learn to program basic”, a series of animated programming tutorials in BASIC lightly disguised as a game.
lesam··on Nuclear waste could power the U.S. for 100 years if utilized
How does this article not talk about France, which had a long-running commercial breeder reactor shut down more by politics than cost?

The real issue is that breeder reactors produce weapons grade plutonium, and so the US doesn’t like to see them built.

lesam··on Docker is dead? Podman – an alternative tool?
Yeah, the main benefit of docker desktop is packaging up a nice Linux VM on Mac/Windows, plus some UI features. There’s a reason ’Docker Desktop for Linux’ came so much later.
lesam··on I'm retiring from the engineering profession
Yes. When I worked in Quebec (around 2017) the company got a reminder from OIQ that employees should not call themselves Engineers on LinkedIn unless they had a P.Eng.

The Engineer title is taken seriously in Canada, similar to how you can’t claim to be a medical doctor unless you actually are one.

lesam··on My students cheated... a lot
And in most courses will just reward cheaters who succeed in not being caught.
lesam··on Inflation is differential and restructuring (2021)
How would you hedge interest rate risk on trillions of dollars in US treasuries? Who takes the other side of that trade, and why? I don’t think that sort of hedge exists.
lesam··on Inflation is differential and restructuring (2021)
Creditors definitely do lose money when they price debt at 2% but inflation runs at 7%.

Talking about mortgages misses the larger fixed rate bond market (government and company long term debt).

lesam··on Two thought experiments to evaluate automated stablecoins
Who pays for security for the room with the dollars?
lesam··on The Vulnerable World Hypothesis [pdf] (2019)
There are lots of examples of encroachments on freedom to avoid the spread of bad tech - e.g. limits on purchasing cough syrup to avoid producing crystal meth, or limits on uses of nuclear power to try to avoid nuclear weapons.

I don’t buy that we need preemptive ‘1984-style’ surveillance for future tech any more than we have needed it for past tech.

lesam··on Ask HN: What happened to Twitter poison pill?
Not quite the same - pre-pill, Musk did not have funding lined up. Post pill, he produced written documents about how he was going to fund the buyout, and had to promise to buy all the shares, not just the first 51%.
lesam··on No one expects young men to do anything and they are responding by doing nothing
Especially since the argument seems to be that ‘elites’ actually live by one set of (good) values while somehow imposing ‘bad’ values or expectations on the lower classes. How exactly are these bad values communicated from the elites if they don’t live by them? How do the elites enforce the ‘good’ values among themselves without transmitting them to lower classes?

I agree there is doublespeak about values among some elites, but I disagree that is the major source of single parent families.

lesam··on Ask HN: What are the next internet infra problems?
That sounds like a business opportunity for a service provider specializing in packet filtering.
lesam··on OpenBB wants to be an open source challenger to Bloomberg Terminal
IMO a core feature of the terminal is that it has a chat program that costs 20K per year to get on. That’s a pretty great filter for figuring out if someone is worth talking to about a 10MM dollar trade.
lesam··on Justice Stevens reads the fine print
I love Nova Scotia’s standard rental terms, with generous term for tenants:

> Use these forms to show the terms that must be part of any lease signed in Nova Scotia. The lease a landlord uses may look different, but must contain all the items shown here. If any of the items are not part of the lease a tenant signs, they apply anyway.

lesam··on Justice Stevens reads the fine print
Re: the house, no, most people don’t sit and read it: https://themortgagereports.com/39671/home-closing-what-you-n... .

Even professional investors with millions of dollars of investments don’t appear to read or negotiate the documents until it looks like it might matter: https://www.creditslips.org/creditslips/2022/03/odd-lots-pod...

People just don’t care that much about legal documents until it looks like it will matter. People’s choice of individual contract provisions at most wage earning jobs, health care, rentals, or vacations is basically nil - they mostly don’t care to read it and so the writers of the contracts put in egregious terms.

lesam··on The takeover of America's legal system
Not just law students, but junior lawyers, in the Weinstein example.
lesam··on I think US college education is nearer to collapsing than it appears
I think the problem with innovation is more the incentive structure. There are too many people trying to p-hack stuff that just doesn’t work well and spin it to get the next grant, and not enough people actually breaking new ground.
lesam··on I think US college education is nearer to collapsing than it appears
They shouldn’t be teaching undergrads.

They should be teaching a few grad students.

lesam··on What is mathematical thinking? (2012)
Also: “my work was extremely valuable to a group of academics, but not worth publishing.”

What?

lesam··on Why America can’t build quickly anymore
NYC taking 17 years to build 3 subway stops doesn’t sound broken?
lesam··on Small subgroups of the population seem much larger to many Americans
You could reconcile it by believing that people just don’t understand percentages.
