What are you gonna do about all the nitrogen etc which the plants need? Are there good ways to reextract these nutrients from dead plant material without releasing loads of carbon at the same time?
nomadluap · a year ago
You can pyrolize the wood by cooking it in an oxygen-free environment, cooking off almost all of the nitrogen and other nutrients and leaving nearly pure carbon in the form of charcoal.

Off the top of my head, for a given amount of wood biomass, you can get about a 70% ratio of product to fuel if you use a high-efficiency wood fire to cook the wood itself.

Then you can take that carbon, bury it in decommissioned open pit mines, or use it as a soil additive (biochar), where it will sequester the carbon for thousands of years and act as a fertilizer.

You could also pair the biochar with a fast-growing swamp tree (willow?), re-incorporating the char into the areas around the willow plantation to create a sort of artificial peat bog which could also be useful for water storage and filtration.

Yea, I hate generation wars, but it seems to be increasingly true that most of the economic value created in the last, say, 50 years, was currently either 1. captured by a few extremely wealthy individuals, or 2. locked up in the retirement accounts and real estate of people over 60 years old.

I feel like we (the younger generations) are all sitting here holding our breath in this stasis, waiting for that generation to die, and hoping those portfolios somehow get magically spread across the population. I don't know what mechanism is available to do that spread, but if it doesn't happen, where will all that locked up wealth go?

I'm sure a lot of it is already spent in the form of reverse-mortgages on homes.

To add to your comment…

I thought the use of paper tape was directly related to the teletypes (when used for I/O with a computer). Where the paper tape could operate as both an input and output mechanism, depending on if you wanted to input a program/text or save a program/text. Paper tape wasn’t a computer storage medium, as much as it was a teletype medium.

In this way, the paper tape hijacked the interactive I/O mode on these early computers to supplant it with a stored format.

I guess you could look at paper tape as a physical manifestation of redirecting terminal I/O to text files using > and < in the shell.

There's no one glove type that works for all substances & situations.
nomadluap · 2 years ago
Can you get gloves made from PTFE? I feel those would be the closest you could get to an "everything" glove.

What's best for, say, my scientific glass bong?

Seriously, what's safe and effective?

Use 99% isopropyl alcohol. Add in a teaspoon of table salt -- it won't dissolve in the alcohol and will act as a mild abrasive to help remove stubborn residue. Rinse thoroughly with water afterwards.

If you're really serious about your cleanliness, a desktop ultrasonic cleaner is also amazing for cleaning bowls and downstems. You can get them for a few dozen dollars from Amazon and the like.

How do you propose that DNS resolution precede without opening a socket?
nomadluap · 2 years ago
For one thing, it could delegate to a local service. Granted, the communication to this service is probably still be over a socket interface, but at least as a purely-local connection you would hopefully have some better worst-case performance characteristics.

This is basically what dnsmasq does when you use it as a local DNS cache.

nomadluap commented on The Plumber Problem   hypercritical.co/2023/08/... · Posted by u/zdw
dudul · 2 years ago
Yeah you need a better name for that, because, while the phenomenon is real, the name is kind of meh. Why not the electrician problem? Or the teacher problem? Any profession would work. Why plumbers? Plus, I can't really recall any movie or novel where expertise in plumbing was essential to the plot.

Editing here because based on some replies my message wasn't clear: I was talking about expertise in plumbing exhibited by one of the protagonists, not someone watching the movie obviously.

nomadluap commented on Parquet: An efficient, binary file format for table data   csvbase.com/blog/3... · Posted by u/calpaterson
cm2187 · 2 years ago
To be honest any file format that would do 1) strong typing/binary data, 2) string deduplication would capture most of the advantages of parquet, except being a column store format which helps in some cases and hurts in others.
nomadluap · 2 years ago
At that point just start using an SQLite database as a data format.

In case it wasn't a rhetorical question, Crew Dragon does not have an airlock that would allow for a suited astronaut to leave the craft while maintaining atmosphere inside it. Plus, a big thing missing is a manipulator arm, such as Canadarm, which was used to capture the telescope, and essentially make the shuttle and telescope one body.
nomadluap · 4 years ago
I always thought it would be interesting if Spacex developed a "dragon utility module". It would launch in Dragon's trunk and consist of a docking port on one end, an airlock on the other, a miniature manipulator arm and a bunch of cargo mounted around the outside. After separating from the second stage the Dragon would flip around and dock to this module, which would give it all the extra bits needed for a mission like servicing the Hubble.

I absolutely expected that. Having both birthdate and age was the Chekhov's gun on that form.

The only thing better would be to have them on different form pages.

And the form clears every time you go back/forward
