CEO of SpaceX alone to do her thing
COO? CEO is Musk, COO is Gwynne Shotwell.
Sooty exhaust from RP-1 and aluminum oxide particulates from discarded upper stages will not be a problem with Starship.
Starship uses methalox, and the upper stage is designed to be reusable.
SpaceX is years behind schedule for delivering crewed space flight to NASA
You are a few years behind the times yourself. SpaceX first flew crew to the ISS in 2020, and have flown 8 more crewed missions for NASA since then, as well as a few private missions.
Boeing (the other commercial crew contractor) has yet to fly a single human :)
Piracy is pretty much the only way the original Star Wars movies are still available.

A couple months ago, I didn’t buy a cheap Blu-ray drive and did not download MakeMKV. Since I did not do this, I can’t report on how great it is.
Why are larger propellers quieter? Does it have to do with the rotation rate required to generate thrust?
Thanks for the link to the GitHub issue! Might there be any chance of prioritizing it for an upcoming release?
It seems like a feature which many users would find significant utility in. Since this post, there has already been another post inquiring about this feature.
Yeah, I heard about it on a podcast a few weeks ago, but didn’t see a video until recently.
Paperclip maximizer: Stone wall edition.
Like electric model airplanes and drones, but larger. Battery energy density is not high enough (yet) to electrify long-haul jumbo jets, but we’re beginning to see the electrification of small short-range aircraft.
True, but that doesn’t send notifications for comments and replies. You’d still have to remember to check it manually.
@[email protected], do you know if this feature is possible for Lemmy, or perhaps already in the works? I had a quick look on the GitHub but couldn’t find anything.
If you want to watch top quality unbiased science content, there’s “smarter every day”, “veritasium” and “3blue1brown”. They’re all great, I highly recommend them all.
Add to that any and all of Brady Haran’s channels: Numberphile (maths), Periodic Videos (chemistry), Sixty Symbols (physics), Deep Sky Videos (astronomy)…
Rober’s always seemed a little off to me, like one of those who enjoys being famous more than the stuff that made him famous in the first place.
It’s hard to exactly articulate the point where a content creator loses me, but I can feel it in my nerd-bones.
You’ve articulated my thoughts more clearly than I could myself. I’ve felt the same way for some time.
Thanks, good to know! Glad to see that the issue has some recent activity.
Ah, so the problem is with how some sites configure (or fail to configure) their metadata, rather than a problem with Lemmy?
Holy crap what is that website. Cant read shit.

Insulated blue light-emitting diodes could banish OLED burn-in for good
News
By Aaron Klotz
published 22 hours agoThis new design change could kill off burn-in, reduce manufacturing complexity, and reduce power consumption in future OLED TVs and monitors.
OLED technology is quickly gaining traction in the PC market and powers some of the best gaming monitors. However, the Achilles heel of OLEDs has always been its burn-in, which inevitably reduces the lifespan of OLED monitors and TVs. No one has been able to fully rectify this issue. However, a new OLED design philosophy created by researchers at the University of Cambridge and reported by Nature has the potential to kill off burn-in for good.
To address this, the University of Cambridge has developed a new OLED design that better controls the light from a blue-light-emitting diode and reduces its power consumption. The blue light-emitting diodes are covalently encapsulated by insulating alkylene straps.
OLED burn-in is generated by the emission of unstable and inefficient light from the blue-light-emitting diode in an OLED display. As a result, putting an insulating material over the blue light diode specifically helps reduce the instability of the blue light protecting the display from potential burn-in issues that could occur.
“Here we introduce a molecular design where ultranarrowband blue emitters are covalently encapsulated by insulating alkylene straps,” reads the Cambridge research paper. “Organic light-emitting diodes with simple emissive layers consisting of pristine thermally activated delayed fluorescence hosts doped with encapsulated terminal emitters exhibit negligible external quantum efficiency drops compared with non-doped devices, enabling a maximum external quantum efficiency of 21.5%.”
This new “paradigm” shift in OLED technology has several positive knock-on effects that will further simply the manufacturing process of OLED displays. Current OLED displays use several layers of specialized materials to help reduce burn-in effects, but the introduction of insulated blue light-emitting diodes means that many of these layers can be deleted entirely from an OLED display, reducing manufacturing costs. This new design is also more power efficient, which should lead to more power-efficient OLED monitors and TVs in the future.
If this new OLED design change proves successful, OLED displays will finally be free from the burn-in issues the technology has had since its inception. Displays could run practically forever and not succumb to any brightness changes or designs “sticking” to the screen.
However, this technology is still in the research phase, so it will take time before we see this design methodology shift to the manufacturing phase, where OLED displays are manufactured with this new design in mind.
Someone should crosspost this to [email protected].
I never watch YouTube while logged in if I can help it, and I’ve never subscribed to a channel either. I’ve just bookmarked the /videos page of the channels I like, and check them regularly.
Also reusable, like Falcon 9.
