jamesmontalvo3··on Astronauts told to return to ISS after sheltering over air leak repairs
There are doors (called hatches) between the segments. Each segment flew up separately and pressurized. So there are actually two hatches between each segment, since there’s one on each.
jamesmontalvo3··on Ask an Astronaut: 333 hours of Q&A footage with astronauts
The centrifuge module was planned at one point: https://en.wikipedia.org/wiki/Centrifuge_Accommodations_Modu...
jamesmontalvo3··on US Job Openings Decline to Lowest Level in More Than a Year
The shape of that graph is roughly equivalent to the shape of labor force participation for women [1]. I don’t think that detracts from your point in regards to the last 20-30 years, but in regards to “before that it was never this high” I think it’s evident that the societal shift of women joining the workforce is the reason, not an improvement in the economy.

jamesmontalvo3··on Americans no longer see four-year college degrees as worth the cost
I think the point is that if you’re going to get a degree in mechanical engineering, you need to study differential equation, and if you’re going to have a well-rounded education, you need to study some history. Both were a requirement in the past, but we’re moving more towards only the former being considered important.
jamesmontalvo3··on Show HN: ISS in Real Time – 25 Years Aboard the International Space Station
Not really constantly. For 20 seconds every 30 minutes or so when it changes what satellite it’s pointed at, plus longer outages throughout the day depending on satellite usage by other systems. This may be just a minute or so every hour on a high-coverage day, or it may include 15-minute outages occasionally at low-coverage times (typically when the crew are asleep)

Is stated in the linked article but in case anyone missed it: same creators as Apollo in Real Time

Awesome work! Surely a huge labor of love to dig up that much content out of the public domain. Congrats on the launch!
jamesmontalvo3··on Baseball durations after the pitch clock
Wouldn’t the minimum be 51? 932 =54, but if the team batting second is winning after the top of the 9th then they don’t need to play the bottom of the ninth, so subtract 3? Not a baseball person.
jamesmontalvo3··on The surprising geography of American left-handedness (2015)
> I wonder if there's information on how many passengers of the Mayflower were left-handed.

Probably 0% reported, considering the negative views towards left-handedness at the time.

jamesmontalvo3··on NASA Stennis Releases First Open-Source Software
Concur that it takes time (it took 2.5-3 years for me to open source github/nasa/coda), but in my experience at JSC it wasn’t red tape, but a lack of staffing in the export office. It seems reasonable to me that some amount of review be performed before something can be open sourced, and the effort wasn’t too much on my end. It just took a long time.
jamesmontalvo3··on NASA Stennis Releases First Open-Source Software
Just to be clear this is one center’s first open source release. There’s open source from other centers at https://github.com/nasa and https://code.nasa.gov/
jamesmontalvo3··on Caltech, long a bastion of male students, enrolls first class of majority women
My daughters, in 2024, still hear “you’re a girl, you can’t be good at math”. My 10 year old is the best programmer on her school’s robotics team, but she hears words like these regularly and she’ll be told she’s not good enough throughout school. My 17 year old is a straight A student, triple varsity athlete, and talented musician, but in applying to colleges she’s repeatedly told me “I couldn’t get into $eliteSchool”. So maybe if there are 20k male and 7k female applicants, those are just the females who fought the societal forces telling them they can’t. Maybe there’d be 70k female applicants otherwise.
jamesmontalvo3··on Mpox: Sweden confirms first case of 'more grave' variant outside Africa
I know almost nothing about genetics or virology, but perhaps GP is saying the close proximity of genetic similarity allows viruses to mutate and infect people it otherwise wouldn’t. For example, say Person A had a virus, and under no circumstances would Person A ever infect Person C due to Person C being just barely genetically different enough from A. Then we put Person B into the mix who is “halfway between A and C” (quotes because that’s probably not precisely how genetics works, but I don’t know). The virus infects B, then mutates and infects C.
jamesmontalvo3··on What adults lost when kids stopped playing in the street
What ages are you talking about? Where I live (in the US) I can’t imagine parents scolding me if I let my kids wander 100 yards from me, unless they were very young.
jamesmontalvo3··on We are at our most creative just before we fall asleep, scientists say (2022)
Shower right before bed, maybe?
jamesmontalvo3··on Are animals conscious? New research
> I am not convinced about the rest of the animal kingdom.

What about crows?

jamesmontalvo3··on How many EV charging stations does the US need to replace gas stations?
While the other replies about the legality of walking away for a short period may or may not be valid, GP was talking about leaving their car charging while they go get a short meal with their family. You could probably get away with leaving your car at the gas pump that long at some gas stations, but if wouldn’t be a very considerate thing to do.
jamesmontalvo3··on Apple introduces M4 chip
Maybe true for a lot of the HN population, but my teenagers are mortified by the idea of me giving them android phones because then they would be the pariahs turning group messages from blue to green.
jamesmontalvo3··on Show HN: Beautiful 3D ISS tracker with live video and near-realtime clouds
I work at Johnson Space Center on an app called CODA [1] that allows us to view all ISS video downlinks in sync with each other as well as with audio and data sources. We can view any moment back to 2013. The plan is to open-source the app, but that of course would not make the data available. We’re heavily plugged into the Artemis program and hopefully will get more of its imagery available from the beginning.

jamesmontalvo3··on BYD launches $15,000 EV
I was looking for a car for my kid last night and stumbled upon this gem: https://www.craigslist.org/about/best/hou/6565526716.html
jamesmontalvo3··on Ask HN: How are you using ChatGPT for yourself?
Sometimes I need to search for something but can’t find the words for it. I can prompt something generally describing the concept.
jamesmontalvo3··on New nuclear deflection simulations advance planetary defense against asteroids
Perfectly chaotic rotation might be worse. If it was a spiral then you could hit it at a pole. I think most things rotate about a semi-fixed axis (not totally fixed, often propagating over time)
jamesmontalvo3··on The case for never reading the book jacket
I don’t even want to see the title of an It’s Always Sunny episode before the cold opening.
jamesmontalvo3··on Amazon Prime Video content to start including ads next year
This is the final straw for me. I’ve wanted to cancel Amazon services for a while but since I have several bundled it was just painful enough to not want to make the effort.
jamesmontalvo3··on Tell HN: Gitlab Premium pricing increases incoming $19 to $29
Not my experience at all, in a similarly sized premium on-prem GitLab. I git-push and the pipeline is running faster than I can get to my browser. Jobs queue basically instantly assuming you have enough runners for your workloads.

I have no experience with using the search. On both GL and GH I prefer to just pull the code and search with my preferred local tools.

Personally I find GitLab CI syntax better to work with than GitHub, particularly if using dependency-based versus using stage-based workflow.

jamesmontalvo3··on What if regular exercise is the best cognitive exercise?
I don’t think the point is that physical work makes humans intelligent in comparison to animals. I think the point is that physically active humans exercise aspects of their intelligence that modern sedentary humans do not.
jamesmontalvo3··on Adding a “duress” password with PAM Duress (2021)
Alternatively: same PIN/password as normal, but alter the last character. Better if it’s any incorrect last character. That allows you to stick close to your normal routine while in a stressful situation.
jamesmontalvo3··on Solar superflares hit Earth multiple times
I think you make a lot of fair points, but when I see comments like:

> anything we're doing now still just feels like tinkering on the smallest scales

I’m reminded of: https://xkcd.com/1732/

jamesmontalvo3··on Ask HN: Who is hiring? (February 2022)
This position is primarily focused on building the map/GIS tools to support lunar operations, but will also be part of the team that's modernizing procedure authoring/execution for spacewalks/moonwalks as well as building an automated apolloinrealtime.org for Lunar, Gateway, and International Space Station. It's an exciting team to be a part of.
jamesmontalvo3··on In 2019 40% of San Francisco traffic fatalities are from left turns
What percentage come from right turns? Is it less than a third of ledt turns, and thus three right turns is safer than one left? Probably more efficient: should map software offer a “limit left turns” option?
