SpaceX Plans to Build a $100 Billion Spaceport In Louisiana

SpaceX plans to spend up to $100 billion building a new Starship launch facility in Vermilion Parish, Louisiana, which the state says could eventually "support thousands of launches annually." CNBC reports: Once built, Starbase, LA will serve as the main launch facility for Starship, SpaceX's in-development rocket that's the largest ever built and designed to be fully reusable. Musk has aspirations to massively expand SpaceX's Starlink satellite network, to launch orbital data centers and to someday colonize Mars. Those ambitions, and justification for SpaceX's nearly $2 trillion market cap, hinge on the success of Starship. SpaceX said, in a video posted to its website on Tuesday, that the search for a site to build launch pads and have access to ample fuel for its operations took about seven years. Musk said in the video that the company would bring "probably 10,000 really exciting jobs" to Louisiana with the spaceport. A fact sheet posted online by the state of Louisiana said SpaceX is expected to generate an estimated "3,000 direct new jobs over the next 10 years" in the state, and "8,100 indirect new jobs." SpaceX said it would work on a "historic coastal restoration" in Louisiana, in partnership with the state to "bring the marsh back" and ensure the wetlands around its new facility will have "storm protection."

CodeSOD: Lock 'Em Dead

The Daily WTF
2 months 1 week ago

Kevin sends us an exception handler from C++. Let's see if we can spot what's going wrong:

catch (Exception::Deadlock) { retry; }

When we catch a deadlock happening, we retry. That's not a keyword in C++, and looking at how it's used, it has to be some kind of macro, and I suspect that the macro is hiding a goto underneath it.

The real problem, though, is that we suspect we're in a deadlock situation. That means this thread is waiting on a resource held by another thread which is waiting for a resource held by this thread. Neither train may continue until the other has passed. So this retry only works if it releases the resource held by this thread (letting the deadlocking thread proceed). But does it?

Not according ot Kevin. The code already had a pile of deadlocks in it, so they brought in a highly paid consultant to try and fix them by reordering access and tracing where mutexes were causing issues. This retry just jumps back up to the top of the block, without releasing any resources. It "seems the consultant wanted to add some deadlocks of their own," Kevin says.

Lab Supply Companies Have Been Selling Antibodies Using Manipulated Images

Slashdot

An anonymous reader quotes a report from Ars Technica: Antibodies play a central role in your body's immune defense. But they're also nearly ubiquitous in biological research, being essential for several widely used lab techniques. While some researchers need to go through the process of producing their own antibodies, antibodies to many key proteins are commercially available and can be ordered for overnight delivery. In May, however, Reese Richardson, a post-doc at Northwestern University, discovered that some of the images used to demonstrate how these antibodies performed in lab experiments had been subject to image manipulation -- the sorts of changes that would get a paper retracted if they had appeared in the academic literature. The manipulations ranged from removing background noise to copying and pasting data to fabricate results. Now, he has done a more exhaustive search and found problematic manipulations in images used to market over 17,000 commercial antibodies. [...] The consequences of this discovery are pretty significant. If you buy an antibody believing it will generate clean, clear data and find it doesn't, many researchers will assume the problem is them. That often leads them to spend time troubleshooting the procedure and trying slightly different conditions to get useful data. If the antibody can't produce those results, all the troubleshooting will have been a waste of time and money. Nature's coverage of the new findings includes quotes from several companies that sell these antibodies that, paraphrased, range from "we'll look into it" to "we don't think it's a problem." Researchers who have spent time frustrated while failing to get an antibody-based experiment to work may think otherwise.
