haldora··on Small, cheap spy satellites mean there’s no hiding place
The nonfiction book Into the Black by Rowland White has a portion about the Space Shuttle's use launching NRO satellites. This is a fascinating use of the shuttle not many talk about.
haldora··on My Eight-Year Quest to Digitize 45 Videotapes
I always had good success with MakeMKV (http://www.makemkv.com), but it's only available on Windows and Mac. I'd then use Handbrake to convert into a more accessible format (maybe shoot for H265?).
haldora··on New technology for aluminum production promises zero CO2 emission
I helped write a report [1] about the state of the Space Resources industry for 2019. This report should get you up to speed on the science, engineering, and law/policy going on in the field.

Our website specifically covers ISRU, including a monthly newsletter and sporadic articles (including one published this morning about minimizing lunar dust kick-up when landing vehicles on the Moon).

Looks good. Installed it and will try it this week! Thanks for sharing.

I was about to start learning KiCad, but I think I'll explore this first.

This is so amazing! Thanks for putting it together and sharing it

Please do! Would love to learn more about how you built it :)

Added a quick fix
haldora··on Show HN: I Am Pickle Rick
Thanks! I added a quick fix :)
haldora··on Show HN: I Am Pickle Rick
Noo! We're just having a few lighthearted laughs :)
haldora··on Show HN: I Am Pickle Rick
You comment is so nice. I keep coming back to it. I'll strive to leave comments like this elsewhere; simple but very powerful!
haldora··on Show HN: I Am Pickle Rick
Sorry about that. Working on a fix. It's currently a bit fickle :P
haldora··on Show HN: I Am Pickle Rick
Hahaha. That is glorious. Thanks for sharing!
haldora··on Show HN: I Am Pickle Rick
Agreed. I noticed that and found it annoying, too. Will work on it! :)

Hmm, next time! I keep thinking of ways to tie in education to a text adventure. Trying to achieve what Walt Disney said:

> I would rather entertain and hope that people learned something than educate people and hope they were entertained.

haldora··on Show HN: I Am Pickle Rick
Hey HN!

This is a silly site based on the Rick and Morty clip of Rick turning himself into a pickle [1] (because ??? he could). The amusement comes from Rick revealing he is the pickle, so I turned that into a command line 'surprise'. When you type "flip-pickle" into the mock-terminal, an asciiart image of Rick the pickle is shown.

That's it... lol. A simple and silly project. I considered making it more of a text adventure, but honestly two days of dev time is more than enough for this app!

Plus I now know how to use a mock-terminal in React, so I learned something. :)

If you are interested in the tech, this is a single page app (SPA) built in ReactJS using the terminal-in-react [2] library. Deployed with docker-compose on my Hetzner server, utilizing Cloudflare. It has 4 sizes of asciiart for different screen sizes, so it works decently well on mobile and desktop. And the favicon! lol.

But back to the serious work.

Check out VimAwesome (https://vimawesome.com) for finding plugins. They provide instructions for installing each plugin via Vundle, NeoBundle, VimPlug, and Pathogen.
haldora··on Ask HN: What is the best chair for developers?
If you are in the Texas area , humansolution (https://www.thehumansolution.com) in Austin has a good selection of chairs. Not affiliated with them. I actually drove a few hours just to try out chairs before placing an order for my Leap. It was delivered without issue (well, except Steelcase mixed up the shipping labels with someone else in CO. lol).
haldora··on Ask HN: What is the best chair for developers?
I love my Steelcase Leap! The cushion is very comfortable and is holding up well after a few years. I sit criss-cross and am able to easily do this with the Leap. The Aeron prevents this because of the hard plastic around the seat dug into my legs. I also got mine with the adjustable headrest, which is very nice for reclining.

I basically live in my chair, so it was a solid investment.

haldora··on Hayabusa-2: Japan Spacecraft Touches Down on Asteroid
At first it is not about metals, but water. Water is the oil of space. You can use it to make propellant, human/plant consumables, radiation shielding, and for further chemical processing. Once you have cheap water in cis-lunar space, it becomes 'easy' to move payloads around the Solar System and start the process for other resource utilization.
haldora··on Small World: The Tiny House Trend
Have you documented this somewhere online, and do you have pictures? Using an old train car sounds very interesting and unique! I'd enjoy reading more.

Thanks for the suggestion! I'm now evaluating a bunch of my prior writing.... Eh that's a lot of red!
haldora··on Birding Like It’s 1899: Inside a Blockbuster American West Video Game
In Blood, Sweat, and Pixels by Jason Schreier, I think he was also quoted as saying his daughter's insatiable habit of repeatedly mounting and unmounting the horse caused a serious bug, which they would not have found otherwise.

I really like that html table you are using! It's featureful and looks great. :)
haldora··on Google Kubernetes Engine's third consecutive day of service disruption
I've been failing all weekend to create nodes in a GKE cluster through either the UI console or gcloud. Even right now I can't get any nodes to spin up.

Edit: I finally got my cluster up and running by removing all nodes, letting it process for a few minutes, then adding new nodes.

> What's wrong with using tons of oil? It's not being burnt so it doesn't contribute to climate change. Are you concerned that it's wasting the valuable oil that would be better used to power a car or power station?

Instead of having a VLCC bringing crude to a Gulf Coast refinery where a large part is converted into propylene for bottle and cap production, the crude could be kept safely in its original well, unused. If the demand for propylene (et al) is reduced, refiners would alter their production to make less, ultimately lowering their crude intake, ceteris paribus.

haldora··on Pandas on Ray – Make Pandas faster
I agree that they should have included a link to the main repository in the introduction, but the 4th paragraph from TFA describes Ray:

Pandas on Ray is an early stage DataFrame library that wraps Pandas and transparently distributes the data and computation. The user does not need to know how many cores their system or cluster has, nor do they need to specify how to distribute the data. In fact, users can continue using their previous Pandas notebooks while experiencing a considerable speedup from Pandas on Ray, even on a single machine. Only a modification of the import statement is needed, as we demonstrate below. Once you’ve changed your import statement, you’re ready to use Pandas on Ray just like you would Pandas.

haldora··on Astranis emerges from stealth with new satellite tech for connecting the world
According to this Motherboard article [1] from Jan 27, 2018, only the Tempe, AZ gateway handles non-military traffic, with the US DOD and Russia operating the two other (military) gateways. I can't remember if the other gateways were shutdown during Iridium's bankruptcy.
