> Also, has anyone though of how mind-numbingly wasteful solar fusion is? All that energy, and only a tiny fraction makes it to Earth with the rest getting dumped wastefully into space. Seems like an area that's ripe for disruption by a startup.

That energy can be captured by a Dyson sphere:

Maybe Incus[0] as an alternative instead of fork.

In case one wants to switch from Hashicorp to alternatives that are similar enough or forks, what would that stack be?

Hashiternative stack:

- vault -> openbao (fork)

- terraform -> opentofu (fork)

- consul -> ?

- nomad -> slurm + something that runs/orchestrates windows jobs?

- hcl -> dhall + nix?

Oh, cool. They implemented a `download_more_ram()` function![0]

Does it crash safely as well? I did not test it, I more than 640 KB of ram.

New comment by hpb42 in "China is building nuclear reactors faster than any other country"

hpb42 — Fri, 01 Dec 2023 19:06:45 +0000

> billions of dollars' worth of safety measures

Is this a bad thing? Investing a lot into safety measures to avoid catastrophes seems better than investing significantly less because we assume is safe.

Could you elaborate on why this investment is an argument against nuclear?

I once talked to people that worked at Angra Nuclear Power Plant in Brazil and they said the real danger is actually the spent nuclear fuel. The power plant itself is safe due to many redundant safety measures, continuous tests and monitoring. I don't have a source for this, and don't take my words for absolute truth, I'm not an expert in the subject.

> kept from harming us by a large crew of skilled people

I'm glad to hear people working with nuclear are skilled ;) I assume people working in solar/wind/hydro are also skilled at their craft. And I'm sure you didn't imply that, maybe the phrasing wasn't the best?

Brazil abolished daytime change a couple of years ago. Our time is the same all year, no more +1 and then -1 hour.

It was mess on the day there should a change, many people arrived on their appointments one hour before or later. Many automatic systems changed their time, different clocks at home reported different hours.

This chaos lasted one morning. After some time, nobody now complains about not having it. Many people don't remember about the change anymore. The only people that complains about daylight change are the ones that work with people from countries that have that.

Abolishing daytime change is not the same as adopting an "universal" (country-like?) timezone, but shows that it is _possible_ to do on a "big country spanning a lot of latitude as well as longitude and tens of millions on wildly different work and sleep schedules".

Maybe the main issue is that many people fear change? (Which is quite "funny", as winter/summer time is a change in time...)

New comment by hpb42 in "The first stable release of a memory safe sudo implementation"

hpb42 — Mon, 06 Nov 2023 12:42:22 +0000

One of those left out features is `sudoedit` or `sudo -e`. I use this a lot when editing files in /etc or any file that my user does not have permissions. The flag first copies the file to a temporary location with permissions for my user to edit, then opens my text editor (defined via $SUDO_EDITOR env var) as _my user_, without any sudo permissions. After I close the editor, the file is copied back with the original permissions only if there were any changes.

The cool thing is running the editor via my user, which loads my user's configuration/plugins, instead of the root user's.
