SLS proponents have been claiming that all of the extra time and money spent on process and formal verification would lead to a rocket that works without having to do lots of trial-and-error like SpaceX. Heck, even the name of the test camp

By web, do you mean websites? Does that include images? JavaScript?

Sadly Linux users are like 1% of the market, non-ext4 is even less (and I am a full-time Linux user and big ZFS fan). They actually restored support for several non-ext4 filesystems over a year ago[1]. 1: https://hub.packtpub.com

If you look at the very end of the second video, you can see that the camera pans behind the cameraman and shows a bunch of people trespassing beyond the barricades. The position the police were defending was already compromised.

I've found that it engages the same parts of my brain as writing software, and I only have a limited amount of time each day that I'm able to focus on either activity. So to some degree it is self-balancing, but it's also pos

The issue is that the sound waves bounce off the pad back towards the rocket. Once the rocket has left the pad, the sound waves proceed behind it and there's no risk of them hitting the body.

Note that the $2M is to launch a fully loaded (100 tons of payload) Starship into low earth orbit (LEO). Launching it further, such as to the Moon or Mars, requires refueling while in-orbit. I've seen estimates from Musk that it would

Yeah, all I've heard is $53M for testing in-orbit refueling and $135M for developing the lunar lander version of Starship for the Artemis program.

But nginx is usually just a proxy for connecting to app servers, and your app servers still need to handle all of those requests.

> In the ones SpaceX didn't win, the winning bid was nonetheless forced lower This sounds like a really satisfying result. Do you have any sources on specific areas where that happened? I was kind of surprised that Starlink wins wer

I think this capacity level is only intended for low earth orbit, maybe lunar missions at most.

The subsidy is spread over 10 years, so they only get $88.5M/year.

Don't forget that the poles are usually owned by an existing power or telecom company, and if they even let you use their poles, you have to pay rent on the pole. Same for conduits. Building new poles and conduits can also be legally d

Actually the pump has to be able to put out as much if not more pressure than the pressure generated in the combustion chamber, otherwise it wouldn't be able to push a steady stream of fuel and oxidizer into the chamber. I recommend wa

Building on the other comments here, SpaceX has more knowledge and certainty about recent and upcoming launch economics than other satellite providers, which opened up the possibility of a system like Starlink. Starlink is capable of such h

Yeah, I'm just so used to watching Falcon 9 landings where it's falling through the exhaust because of atmospheric drag.

by maccam94 6y ago
If you flip around and fire the engines to decelerate, you would be flying into the exhaust. Edit: Actually this hurts my brain. If you're going 1,000,000MPH and fire propellant at 500MPH in your direction of travel, it would travel at

The post makes a huge leap which doesn't make sense to me. They claim that it makes sense to not test the use of security privileges in CI, and instead route "reports" to a separate security team, who will then somehow know w

Up until 2005/2010 (the start of ITER), it was more like 30+ years away (ex: https://imgur.com/3vYLQmm ). 5 years is a while but 2025 has been the target for CFS for several years now.

It is absorbed by the FLiBe salt blanket in the ARC design and converted to heat. The hot salt is circulated out and the heat is used for power generation before the salt is recirculated.

The SPARC design uses a combination of extremely high strength magnetic fields to contain charged particles inside the vacuum chamber and a molten-salt blanket (FLiBe) for neutron capture and cooling. They believe this will be a viable cont

NetworkManager is the one exception I'm aware of here, but I don't think any server distros use it. Using NM is also the best option for configuring desktop environments, so I wouldn't bother disabling its resolv.conf managem

I'm pretty sure that just replacing the /etc/resolv.conf symlink with a regular file will prevent all of the major network configuration tools from modifying it. I've verified this for resolvconf and systemd-resolved at

SpaceX's next-gen rocket, Starship, will have a 9 meter fairing and aims to be able to launch 100 tons into orbit for ~$10-100/kg. They also plan to support 3 launches per day. LSST has a primary mirror that's 8.4 meters wide
