sandgiant··on The hunt for Nigerians who can change into cats
Not sure if you're joking, but no, that doesn't make any sense. Asphyxia is a lack of oxygen, not an excess amount of CO2. Even slight increases in CO2 will make you feel extremely uncomfortable, long before you actually run out of oxygen.

The audiobook edition read by Simon Prebble is one of the best I've heard.
sandgiant··on Show HN: I made a privacy-first minimalist Backblaze
This looks really great! I love restic but miss a simple UI to keep track of my backups. Will definitely keep an eye on this.
sandgiant··on Help preserve the internet with Archiveteam's warrior
Can you provide some details on this? I'm curious how noise and signal are defined and measured in this case.

sandgiant··on How to skate a 10k
That's an interesting question. I've never found an activity I could spend that much time on, besides perhaps playing computer games when I was a kid, but even that I would get tired of sometimes.

I don't think these people are fundamentally, orthogonality, different, but I assume they are outliers on some spectrum of features where most people are closer to the median.

sandgiant··on How to skate a 10k
This might be a language thing. In Denmark "elite" is the official label assigned to those who compete at the highest level in any given sport. So say a runners club may have an "elite" team or "elite" runners. It's just a label really, nothing else.
sandgiant··on Daily chart: A new low for global democracy
This is not true at all.

The constitutional powers of the monarchs in Scandinavian countries do not at all reflect reality. The monarchs have no power to influence politics or elections outside of public or international relations.

sandgiant··on Daily chart: A new low for global democracy
Last time in Denmark was in 1920 [1]. It almost abolished the monarchy at the time. Since then no other monarch have dared interfere with politics.

Today all political interactions are purely ceremonial. The monarchy is still part of the power elite, and of ceremonial importance in domestic and international relations, but they have no direct power over political decisions or elections.

sandgiant··on The Curse of NixOS
This mirrors my (very limited) experiences with Nix. I've so far only dipped my toes in home manager, but being able to share shell config and cli tools declaratively between WSL, linux and MacOS with very little branching has been great!
sandgiant··on Emergence of Life in an Inflationary Universe (2020)
We might never know with complete certainty, but then what can we know? Exploring the limits of the theories we pose is the only way to gain knowledge. The physical world is after all fairly predictable. Even if we will never know anything with certainty.
sandgiant··on Emergence of Life in an Inflationary Universe (2020)
Indeed we might never be able to measure the global normalization of the likelihood function of life, but that doesn't mean we can't investigate it's local properties. In fact, I think we can learn a lot from doing just that.
sandgiant··on Emergence of Life in an Inflationary Universe (2020)
There is a sort of philosophical upper bound on the total size of the Universe in an eternal-inflation scenario. This is the Boltzmann brain paradox. The argument goes that if there are infinitely many universes it is infinitely more likely for you to be a brain randomly fluctuating into existence in the vacuum, rather than being an actual human being evolved through evolution.

This conclusion is obviously absurd, so the argument goes that there can't be infinitely many places in which random things can happen in the Universe. Note that the size of the Universe required to produce a Boltzman brain is much larger than that discussed in the article. It's still nice to think that there might be an upper bound for us to avoid some of the more daunting implications of the anthropic principle.

sandgiant··on What it means to teach gifted learners well
I lost all interest in the school system when experiencing all the "Inappropriate Instruction(s) for Gifted Learners" from that article. Started playing computer games instead and smoked weed every day for several years. University was the first place I really felt challenged. Ended up doing a PhD in physics. I sometimes wonder how much more (if anything) I could have achieved with the right instruction early on. Sometimes I wonder if I should try teaching.
sandgiant··on A Better Git Flow
Rebase is great, but it's usefulness really depends on the commit history.

If your branch consists of 10 commits of trying various things, then the sum of changes in all the commits can easily become significantly larger than the final branch diff. In that case resetting is orders of magnitudes faster than fiddling with rebase.

sandgiant··on How are Rome's monuments still standing?
Destroying symbols of a previous rule was (is) commons practice. Constantine realized that some building and monuments were worth preserving and repurposed them as "Christian", thereby ensuring their preservation for hundreds, or even a thousand of years.
sandgiant··on Against 3x Speed
Psychology in Seattle has some excellent well researched content. It has very concretely changed or modified my perspectives on relationships, parenthood and mental illness.

The "deep dives" are definitely the best.

sandgiant··on HTTP/3 Is Fast
Indeed. And if they don't you are probably better off normalizing your axis anyway.

sandgiant··on Daddy isn’t coming back
Thanks for sharing. Getting the right treatment is such a gamble. I wish we were better at talking about mental illness openly instead of stigmatizing it. Perhaps then we would realize the need for better treatments and funding. I have a close relative that's been all the way down the hole with life-threatening mental illness, but recovered due to doctors finding the right cocktail of medication and safe environment. Getting to know this person I'm humbled by how ignorant I've always been on issues of mental health. I shudder when I read comment sections like this one, or talk to friends and family, as I'm reminded how pervasive this ignorance still is in the general public, and even in professional healthcare. I have the deepest respect for people like you, that are hanging on in spite of the terrible circumstances you've been given. I hope you find some shivers of light in between all the darkness.

I don't think there is such a thing as broken beyond repair. How would you even begin defining that? If you're thinking in economic terms then sure, we can try to optimize a limited budget to save/improve the maximum number of lives. It would still be beneficial to have at least a few people look into whether new methods can be developed to increase the amount of "good life" you get per dollar. Giving up and deciding something is beyond repair can be one course of action in this optimization, but it seems counter productive, and perhaps a bit unethical, to try and generalize this position. Having the thought, and the discussion, is obviously totally fine.
sandgiant··on New mineral davemaoite discovered inside a diamond from Earth's mantle
> No one has ever successfully retrieved a high-pressure calcium silicate from the lower mantle before. This is because the high-pressure CaSiO3-perovskite is “unquenchable,” meaning that it cannot retain its structure after being removed from its high-pressure environment.

> “When we broke open the diamond, the davemaoite stayed intact for about a second, then we saw it expand and bulge under the microscope and basically turn into glass,” says Tschauner.

sandgiant··on Restic – Backups Done Right
I've used restic for over four years. It's been rock solid on all platforms (mac/windows/linux). I've set it up on everything from beefy linux servers to 10 year old Windows machines (scheduled job running for 3+ years, pruning on a separate machine, never had any problems). The support for B2 and S3 compatible backends as well as rclone makes it a breeze to set up. The community and maintainers are also very friendly and helpful. Highly recommended!
sandgiant··on Restic – Backups Done Right
You can use `restic mount` to mount a repository and browse and restore backed up files using your file browser GUI of choice. Works quite well.
sandgiant··on Backblaze S-1 IPO
Not sure exactly what you're after, but if it's FOSS then I would definitely recommend https://github.com/restic/restic or https://git-annex.branchable.com.

As others mention a lot of closed source tools offer local encryption, including Backblaze (although I believe they need your key in order to do restores, which might or might not defeat the purpose depending on your use case).

sandgiant··on Apple Maps' Acceleration (2020)
> Perhaps the most noticeable difference between Apple’s old and new maps is all of the vegetation detail Apple has added.

I really don't understand the way they blend forests and fields together. It used to be that forests and grasslands were marked green and agricultural land was white, so you could easily tell the difference. Now they are the same, or nearly the same, color while the difference in landscape is massive. To actually tell the difference now you have to switch to the satellite map.

I don't see how this is adding more detail. If anything it's providing less information.

sandgiant··on James Webb Space Telescope launch media kit [pdf]
This is a pretty strong claim to make without any arguments to back it up. Do you have scientific arguments as to how 10 telescopes at 1/10 the cost would have been better?
sandgiant··on Fundamental physics sees worlds in grains of sand and infinities in hours
Not supported by data. There is plenty observational evidence that the redshift is due to cosmic expansion, e.g. galaxy surface brightness evolution, CMB, time dilation, the list goes on.

The website you link poses a number of unsubstantiated claims without any answer to the numerous problems it raises.

Then he links to this hilarious notebook; https://colab.research.google.com/drive/1K1qoUFvqZp1fWbpcKJW...

I don't mean to sound rude but this doesn't look like the work of someone who has spend any considerable amount of time actually studying the Universe.
