Comment Re:Compare Starship to the Saturn V (Score 1) 163

NASA got men to the moon by blowing a snotload of stuff up (see e.g. the combustion instability problems of the F-1 engine, which were solved by trial and error over a large number of iterations). The difference is that they did it all on test stands, before committing to a first flight.
SpaceX decided to go from test stands to flight testing early on, because the hard part of Starship (returning the two stages to land) cannot be tested well on a test stand. It's an approach that has worked for them before (developing the first stage landing and recovery for Falcon 9).
This approach has also been used by others: the USSR did it for the Proton and N-1, needing 14 Proton launches before the rocket was ready for operational use.

This is just a guess, but I'd add that the extra layers needed to achieve the required thickness / strength also increase the likelihood of voids and other flaws which would be potential failure points.

Definitely. Scott Manley did a comprehensive video on the engineering issues.
Oceangate made the hull by laying up a series of CF layers about 2 cm thick. Their process was bad enough that at this thickness they'd have a bunch of waves in the layers, adding extra thickness. Then they'd machine the cylinder to flatten out those waves, then they'd stack up more CF, creating new waves. The photos of the wreckage show the hull has delaminated on the planes where they machined the hull.

Comment Squandered an early lead (Score 1) 112

I recently read An Atomic Empire, by C.N. Hill. This is a history of the British nuclear power program.

Britain was the first country to exploit atomic energy on a large scale, and at its peak in the mid-1960s, it had generated more electricity from nuclear power than the rest of the world combined.

They invested massive amounts of money in both initial R&D and in a series of commercial reactors. The path they chose was a bit unusual (the Magnox reactors were gas-cooled), but they ended up with standardized designs that were built in decent numbers and provided up to 26% of the nation's power needs.

That changed in the 1980s, when the power generation industry was privatized. This scuttled investment in the next generation of reactors, and only one nuclear powerplant was built since.

This is a pattern in post-WW2 UK: build an early lead, then squander any advantage they had through lack of follow-through.

Lead. Lead as in the opposite of 'follow' is written as 'lead' everywhere. 'lede' was used to avoid confusion with lead (Pb), the stuff newspaper type was made of. Since nobody has used Pb to cast newspaper type for decades, this use is archaic and unneccessary, making it pretentious hipsterism and not a serious word.

In my experience, a restart WILL occur overnight without notification. My company sets a deadline for restarts. When that's in place, it's going to restart no matter what.

Also if you leave unsaved work running on your computer overnight then you deserve to lose it.

My home computer (MacOS) has been able to do restarts and system upgrades *without* losing any work for years now. Clearly this is a solvable problem.

Windows 11 still has "fuck you" style restarts today. I have notification switched on, and if I very carefully manage it I can prevent data loss by saving and closing my applications manually. I never get the computer back in the state I had before the restart though.
I've had occasions where the notification popped up, with the "restart now and lose all your work" button in front of a button I was about to click, and guess what happened.

And yes, if a restart does happen because you left your computer running a process overnight and it fell idle at 3 AM, guess what: you lose all unsaved work.

Submission + - 50+ House Democrats demand answers after whistleblower report on DOGE (npr.org) 2

echo123 writes: Over fifty Democratic lawmakers have signed a letter demanding answers from senior U.S. government officials about a recent potential exposure of sensitive data about American workers.

The letter is addressed to the acting General Counsel of the National Labor Relations Board, William Cowen. The independent agency is in charge of investigating and adjudicating complaints about unfair labor practices and protecting U.S. workers' rights to form unions.

The lawmakers, who are part of the Congressional Labor Caucus, wrote the letter in light of news first reported by NPR, that a whistleblower inside the IT Department of the NLRB says DOGE may have removed sensitive labor data and exposed NLRB systems to being compromised.

"These revelations from the whistleblower report are highly concerning for a number of reasons," the lawmakers wrote in the letter to Cowen. "If true, these revelations describe a reckless approach to the handling of sensitive personal information of workers, which could leave these workers exposed to retaliation for engaging in legally protected union activity."

The letter refers to an official whistleblower disclosure made by Daniel Berulis, a cloud administrator in the IT department of the NLRB, who also spoke to NPR in multiple interviews.

In his disclosure, Berulis shared that he initially became concerned in March when members of President Donald Trump's Department of Government Efficiency initiative arrived at the agency and demanded high-level access to the systems without their activities being logged. Those fears escalated after he tracked a large chunk of data leaving the agency at the same time as many security controls and auditing tools were turned off, the disclosure continues.

Ultimately, Berulis became concerned that DOGE, which is effectively led by Trump adviser and billionaire CEO Elon Musk, could have accessed sensitive internal information about ongoing investigations into U.S. companies, witness affidavits and even corporate secrets. The alleged insecure practices and removal of data could also create vulnerabilities for criminal hackers or foreign adversaries to exploit, Berulis explained in his official disclosure.
