notfish··on Autophage rocket engine consumes plastic fuselage for fuel
You could probably put some low effort cables from the engine to the top of the stack and add pressure as needed without too much effort
notfish··on Six lesser-known but seriously useful Linux commands
True, but this works in a completely uncustomized shell which is pretty nice - I can hop on a coworkers keyboard or a machine without my .bashrc and it just works. It mostly just replaces spamming the up arrow to find commands I already ran.
notfish··on Six lesser-known but seriously useful Linux commands
Not quite a command, but ctrl+r in bash does a real useful history search
notfish··on Let it snow in your terminal
It didnt work :(
notfish··on Wages are rising. Jobs are plentiful. Nobody's happy
If you make the same as you did pre-covid, you took a 16% pay cut since 2020.

notfish··on Starship Integrated Flight Test 2 at 7 Am Central Time
Gps uses satellites, and basically the only high speed internet you can get without a house is starlink. Both get better with starship

notfish··on Amazon Time Sync Service now supports microsecond-accurate time
…why? My napkin math says a pair of observers, one at sea level and one on the top of a 14,000ft mountain, will drift by about 15 microseconds per year.

In other words, the approximation that time is not relative breaks down at this level of accuracy - there’s literally no value in trying to synchronize things this closely.

notfish··on Starship will attempt a launch this Friday
Good fucking point
notfish··on Starlink achieves cash-flow breakeven, says SpaceX CEO Musk
1.5 million customers according to google, ~$100 per month per customer is like 1.8 billion cashflow in per year, seems possible to me.
notfish··on Drugmakers are set to pay 23andMe to access consumer DNA
Anecdotal, but I paid $300 to get a 30x coverage full human genome scan of myself from Nebula Genomics.

Within 24 hours, before I had mustered up the courage to read my results, I started getting ads for early onset parkinsons meds.

I’ll give you one guess what disease I happen to be extremely genetically predisposed to based on the results of the scan...

notfish··on Mars has a layer of molten rock inside
Mars has water and CO2, thats why starship uses methane. You can make fuel on mars.
notfish··on Mars has a layer of molten rock inside
Nitrates on earth range from 10-50 mg/kg in soil, on mars they make up 1100ppm = 0.1% = 1mg/kg, so in the extreme you can convert 10% of martian land to soil. Seems like plenty.

We just don’t know if the 1/3 gravity will cause bone loss problems - going to the moon is the best way to study it, but who knows. Probably, people will just age 3x faster in terms of bone mass on mars. https://en.m.wikipedia.org/wiki/Spaceflight_osteopenia

And yeah, the first years of a mars colony are gonna be dependent on earth. We’d definitely make sure we have enough rockets that they can abort if shit goes south on supply missions, but there’s no reason earth can’t supply them at first.

You could totally just dig a 1 meter deep hole with a fancy bulldozer, then plop down a prefabbed house and bury it

Hell, you could even have humans do the digging assisted by machines and just live on the surface for the first few months while they build

notfish··on Mars has a layer of molten rock inside
Probably, you dig a hole then put an inflatable hab inside and bury it? This feels like a supremely solvable problem
notfish··on Heslington Brain
How is ritual sacrifice different than execution for crimes other than ruling body? We did some pretty ritualistic stuff to criminals in 1600s england: hanged until half-dead, then drawn and quartered.

It doesnt take 27 years to get to mars. If you push, you can get it down to like 8 months or shorter - it depends how much fuel you bring.

notfish··on Mars has a layer of molten rock inside
Pretty sure we could design and launch a digging robot in 10 years, I dont really buy that as the bottleneck to mars exploration
notfish··on Mars has a layer of molten rock inside
There are nitrates on mars, nobody is seriously proposing unconditional one way trips, mars has enough gravity to prevent bone loss.

But yes, it does mean bringing your own air and being self sufficient, but we do both of those things on the ISS already

notfish··on Mars has a layer of molten rock inside
I feel like spacex is the only group that has a chance at landing on mars this decade, and Starship is exactly what we’d want if we were trying to make a self sustaining mars colony right?
notfish··on Mars has a layer of molten rock inside
Or maybe it has gotten easier to watch things than it was in 1969?
notfish··on Cloud giants sound alarm on record-breaking DDoS attacks
Why does this title read like the hook to a dnd session

We have >8000 lasers in orbit on starlinks right now

notfish··on Don’t throw out those used coffee grounds–use them for 3D printing instead
Carboxymethl cellulose can be made from wood pulp and acetic acid (vinegar). Xantham gum is usually made from fermented sugar.

Both seem pretty biodegradable to me actually, which is surprising.

notfish··on Ask HN: How to avoid social media enshitification, if no one pays for it?
FYI the Uyghur genocide thing was spread in the western world primarily by Adrian Zenz https://en.m.wikipedia.org/wiki/Adrian_Zenz

Dude works for the “Victims of Communism Memorial Foundation”, a US government propaganda branch. He’s not really a reliable source.

notfish··on Starlink's User Terminal Firmware
Its wild to see some of our internal code getting reverse engineered like this. What an incredibly cool read, thanks a ton for sharing!
notfish··on [dead]
Not sure we needed the author to use that many words to say that they have a high school level understanding of human reproduction. I know I’m probably feeding the trolls here, but lets maybe leave the nonscientific hate rambles to every other social media site.
notfish··on A look into the finances of SpaceX
Musk is chief engineer - he makes engineering decisions at SpaceX and has a reputation for mostly making good ones
notfish··on Andrew McCalip demonstrates synthesis of LK99
I’m not sure I understand your point. Are you trying to say that people shouldn’t be paying attention to this? I would personally be horrified if I found out that the paper on the synthesis of a room temperature superconductor went through the normal peer review process instead of letting the world know they discovered something huge.
notfish··on Origin of correlated isolated flat bands in LK99
Defining LK-99 as “the thing you get from following the steps in this paper” and not “the allegedly superconducting material these guys have a sample of” is silly.
