Infernal··on Like an Uncut Cake: The enduring appeal of the hard-copy encyclopedia
Why that one in particular?
Infernal··on Demystifying Apache Arrow (2020)
As someone new to Arrow/columnar DB's, do you mind sharing what kind of data makes sense to use Arrow for, but isn't very compressible?

Infernal··on “Judas goats” were once key players in meatpacking plants
I believe bacon just describes the cut. In my area of the US, you can buy a package of uncured bacon right alongside the usual cured varieties. I don't know for sure, but I'd imagine the slaughterhouses described here wouldn't be doing any processing outside of the slaughtering, butchering, and packing.
Infernal··on Nascar driver stuns to qualify for championship with GameCube move
> Or load the car with cold (more dense) fuel.

This is why F1 specifies fuel capacities and flow rates in kilograms.

Infernal··on Nascar driver stuns to qualify for championship with GameCube move
I also wonder when someone who might normally qualify at the end of the field will do this in qualifying, essentially trading extra repair work on the car for a spot at the front of the field.

Coincidentally, Denny Hamlin was the target of the move both this past weekend and in the linked article above.

Infernal··on Looped Square Or ⌘
I seem to recall that up to 2012 or so, the apple logo was printed alongside the looped square on the physical key. We used to refer to it as the “apple key” (2000s CS program anecdote) and I recall it taking a while to adjust to referring to it as the command key.

EDIT: now that I follow the link I see this information is in the first line. Oh well!

Infernal··on When the push button was new, people were freaked
Strange, my experiences with unionized labor have found the exact opposite - safety conscious to the nth degree, and much more likely to criticize each other for working too quickly than too slowly. They seem to be incentivized to 1) not get dinged for safety infractions and 2) get as many billable hours out of every work order as possible.
Infernal··on Someday aliens will land and all will be fine until we explain our calendar
I have a hard time finding clothes that fit due to being way out on the edge of standard sizing. I have found this similar inconsistency, e.g. I’ll find something I like in my size, order one of each color, and invariably one or two out of four items (that should be roughly identical) will be an 1.5-2 inches out of spec in a way that makes a huge difference (like waist, or inseam, or sleeve length).

Aw yeah, I saved up for a VooDoo 3 just for playing Tribes on my 56k modem, fall 1999 - running windows 98 on a Packard-Bell that we got from Circuit City…
Infernal··on A long-haul flight with no breaks or meals: The godwit’s epic journey
The article mentions that survival of the trip is “above 90%”. I assumed that was one direction, but I suppose it could be round trip.
Infernal··on A long-haul flight with no breaks or meals: The godwit’s epic journey
I'm really curious about the evolutionary path these birds may have taken to an adaptation that allows them to fly 8-10 days non-stop. A couple ideas, assuming that any change evolution can keep up with needs to be gradual/incremental:

Could they have been making this journey since the land masses in question were significantly closer together?

Could they have originally migrated between closer locations, but as weather warmed post-ice-age they slowly increased the length of migration between "temperate northern hemisphere" and "temperate southern hemisphere" climates?

Could sea level rises post-ice-age have covered over islands that were formerly stopping points, or pushed back shorelines that effectively increased the distance required?

Curious to hear what other ideas folks might have.

At one point TFA seems to indicate they lose 50% of their weight, dropping from 2lbs to 1lbs.
Infernal··on Hacking anything with GNU Guix
So, having removed the immutable attribute from / and run the guix-install.sh script, the first issue I have is that the script thinks the group 'kvm' exists, because 'getent group kvm' returns successfully. However, if you try to create a user and add them to the kvm group, you get an error about the group not existing. Looking at the contents of /etc/group, there are only 5 groups and none of them are 'kvm'. At the very least it seems that the Guix install script is making some assumptions about the system that Silverblue breaks, which does make me wonder a bit about using the two side by side.

Additionally, I have found some posts as far back as 2017 regarding using Guix or Nix on Fedora Atomic Linux or Fedora Container Linux (it seems the Silverblue name is more recent) and the fact that we're still puzzling it out 5 years later without much in the way of documented success does make me question the viability of the idea a bit.

Infernal··on Hacking anything with GNU Guix
So you can create /gnu/store on Silverblue with the commands (as root)

  chattr -i /
  mkdir -p /gnu/store
  chattr +i /
The last command restores the immutable attribute on the root filesystem. I am able to write arbitrary files (e.g. `touch /gnu/store/test`) even with that attribute set, so it isn't inherited by subdirectories (maybe obvious).

Now, persistence of the /gnu/store data could be an issue, I'm not sure, but maybe this gets you started?

EDIT: next step is to get Guix installed and then try to update the system, we shall see how it goes

Infernal··on Hacking anything with GNU Guix
I'm downloading the silverblue iso right now to play with this in a VM. It is surprising to me that ostree does not let you do any sort of bind mount or symlink of a non-reserved location like /gnu to some other filesystem, so I'll have a whack at it.
Infernal··on Excuse me but why are you eating so many frogs
As someone who has not "used GPT-3" what does it mean to say that you used it to make a summary? Just dump the full text of the article into a tool and request a summary output?

I have only seen GPT-3 used when it takes a prompt and then generates more related text, I didn't realize you could run that process in reverse.

Infernal··on Show HN: Simulate dollar-cost averaging in any mix of stocks
The post you're replying to: > dollar cost averaging the market only works for those (1) who never sell

The article you link to: > The only other rule in this game is that you cannot move in and out of stocks. Once you make a purchase, you hold those stocks until the end of the time period.

Infernal··on Why A4? – The Mathematical Beauty of Paper Size
If you want to fit the area into the name you can think of it as

A0 = 1/(2^0) m^2

A1 = 1/(2^1) m^2

A2 = 1/(2^2) m^2

And so on

(EDIT for formatting and also to observe a sibling post to mine is making the same point)

Infernal··on The optimal amount of fraud is non-zero
> The optimal amount of crime in a society is non-zero because a society with zero crime would be a dystopian police state where innocent people sometimes get caught up in the justice system's net to make sure it catches all of the criminals.

At this point you're just playing with the definition of crime. I would argue that it is criminal to deprive an innocent person of their freedom, and challenge that your proposed scenario is actually "zero crime".

Secondly, you talk of catching "all of the criminals". In a "zero crime" environment there are no criminals - by definition if there is a criminal, then a crime has been committed at some point.

All that said I agree with your larger point - the cost of freedom is that people are not constrained before the fact from committing crime, and that's a good thing on the whole.

Infernal··on American policy is splitting state by state into two blocs
So that 50% more is by revenue I think - probably difficult to find, if it even exists, but I'm curious what that table looks like sorted by calories instead of dollars.
Infernal··on Supply chain resilience is a requirement for agritech hardware
I am curious, but surely the $900-$1400 an acre is based on rows configured for tractor-based tilling/plowing, fertilizing, herbicide etc.? As I understand it, the nice thing about a smallholding is that you don't have to mechanize near as aggressively, and therefore can plant much more densely than a tractor-based farm would.

As I read through this incredulously, I was relieved to slowly realize Murfie was a company, and not a person.

I think it’d be more efficient to simply pump the ocean out of the environment.
Infernal··on Come for the Broadcast, Stay for the Mets Game
As a Braves fan, I enjoyed seeing some of these new-to-me angles and features in games I saw on other broadcasts. I wish the Bally Sports South crew had some more playful takes like this. The Buck Showalter hit-by-pitch feature is pretty dang funny https://www.youtube.com/shorts/-t536p141B8
Infernal··on 6 Raspberry Pis, 6 SSDs on a Mini ITX Motherboard
I want to preface this - I don't have strong opinion already here, and I'm curious about Ceph. As someone who runs a 6 drive raidz2 at home (w/ ECC RAM) does your Ceph config give you similar data integrity guarantees to ZFS? If so, what are the key points of the config that enable that?
Infernal··on SSH tips and tricks
It can also be used for nested connections. E.g. if you SSH to server A, and then from server A to server B, ~. will kill the session on B. Alternatively, ~~. will kill the session on A.

EDIT: I started distrusting my memory here and went hunting, it appears my memory has the escape nesting backwards https://lgfang.github.io/computer/2009/05/08/quit-nested-ssh...
