To be clear to everyone here: The primary reason why Artemis 3 is not landing is because the billionaire-run Human Landing System contractors are not performing to schedule. The landers are just not ready.
In this test, Artemis 3 will dock with a starship in Earth orbit, but the starship will not even have a cabin interior fitted.
Artemis 3 is going ahead with no landing either. Orbital test only.
It’s pretty common for natural gas electric plants to use Brayton cycle turbines, which is the same thermodynamic cycle that the turbojet engines on airplanes use. But you can optimize the designs on the ground for efficiency (and zero thrust) instead of thrust-to-weight.
It’s also common to use “combined cycle” technology which mashes the Brayton cycle engine together with an older-style steam loop for extra efficiency.
After reading the article, I think they’re just saying they installed some miniaturized natural gas plants. I don’t think they’re literally running aircraft engines on the ground.
Most systems I use will keep a sudo authentication session open for several minutes, so you don’t have to repeatedly enter your password on every single command.
I think the poop bags were mainly stowed into lockers on the sides of the descent module. They’re not just piled up on the ground.
Edit: Correction. This research suggests that the procedure was to “jettison” the “waste receptacle,” containing any sealed poop bags, food wrappers, and other trash. “Jettison” definitely sounds more like tossing stuff out the door.
I also want to point out that maybe 96 bags were provisioned and left. But almost certainly most of those remained empty. Pooping into a bag in the LM in close proximity to your colleague is not an easy or pleasant experience. Astronauts had access to lomotil and they were conditioned on what NASA called a “low residue diet” for the entire duration of the flight and pre-flight quarantine. The early flights were on the surface for less than 24 hours. So there was a lot of opportunity and incentive to just avoid having a bowel movement on the moon.
There’s also a radio transcript from Apollo 16 that suggests that, on that flight, this material was transferred off the returning LM back onto CM and presumably returned to Earth.
But it would still be more expensive, and still have a latency issue.
Imagine a public counterstrike server where there’s an extra 30-50 ms delay between when you hit the strafe key and when you start moving.
Alternatively, Counterstrike or another shooter could defeat wall hacks if the server only told the client about player positions in the client’s line of sight. But then the Counterstrike player executing a peek would see their opponent pop in 30-50 ms after they gain line of sight. Much Counterstrike gameplay is built upon the short interval between when you see someone, and when you click on their head with your hit scan weapon.
Furthermore, latency is not going to go away for Internet play. The speed of light travel time to circumnavigate earth is 125 ms. That gives a theoretical worst case minimum ping of 62.5. Actual pings I see from my ISP are approaching the speed of light order of magnitude, assuming they are only traversing North America.
The traditional rationale, back in the time of the boomer shooters, is that the server doesn’t have enough computational power to update and control the game state for all clients at once, with acceptable latency.
There was at least one “AI” company that was caught passing off the cheap overseas labor as AI.
Well see, they do actually have a list that says what everything costs. It’s called the Charge Master List. They just don’t want you to see that list, because they think it puts you at a negotiating disadvantage. It’s the magic invisible hand of the free market, at work to make pricing information available to all in the most efficient manner. (/s)
This headline sounds like the start of a decent Bond film.
At the time that C was designed, ASCII was not a universal standard. It was one encoding competing with other encodings.
In C and C++, the source character set is implementation defined. This means that each compiler sets its own rules about what characters are accepted. For example compilers could choose to accept ASCII or EBCDIC or Unicode, or some combination, etc.
So the ISO standard will say that ; character is the end of statement punctuation. But it is up to the compiler to say which character(s) or code point(s) represent the ISO ;.
The ISO standards also require compilers to define a separate execution character set to specify values that can be stored in char and used with the string library functions. The execution character set doesn’t have to be the same as the source character set.
Edit: I should also mention that the rules for this stuff are changing a lot in ISO C23 and C++23. (Which standards I haven’t yet personally adopted.) Basically the ISO 23 standards mandate compilers to support UTF-8 source files, and they map every source character in the ISO standard to its corresponding Unicode character.
It changed a lot. Even if you ignore the stuff that happened between the king and the emperor, that emperor changed a lot. Massive legal reforms. Upended world order. Etc. Etc.
Well, for one more moment anyway.
Fun fact: “jet propulsion”, aka turbojet and turbofan engines, was never a topic of study at any point in JPL’s history. The name was chosen to disguise the fact that money was being spent on more experimental rocket R&D.
Yeah, the damage curve is exponential by axle weight.
Renea Gamble was found by a municipal judge to be not guilty of disorderly conduct, resisting arrest, disturbing the peace, and providing a false name to law enforcement. (The allegedly false name was “Aunt Tifa,” which is hilarious).
She has filed a civil claim seeking monetary damages of $2 million and attorneys fees.
Likewise, Chernobyl reactor 4 suffered its mishap in 1986. Reactors 1, 2, and 3 remained operational and on the power grid. Reactor 2 continued to operate until 1991; reactor 1 until 1996; and reactor 3 until 2000.
The fuel wasn’t completely removed from reactors 1-3 until 2013. Just to give you all some idea about the timeline of nuclear decommissioning.
Yes. Those dark spots are plains of actually darker rocks, specifically basalts. That generally means that those are dried out lava fields.
