  • The reverse. OceanGate saw how planes were being built and said, “let’s do that for submersibles!” even though in airplanes, composites are subjected to <1 atmosphere of tension loading and <2g aerodynamic loading, whereas their submersible was going to be subjected to >400 atmospheres of compression loading, and a much more corrosive environment.

    Composites in aircraft have a fairly long and uncontroversial history, and there’s nothing inherently wrong with them in that application. The biggest problem with composites is what happens with them at the end of their service life. Finding ways to recycle them without compromising safety is a good thing, and if it weren’t for Boeing having such a damaged reputation at the moment I think nobody would bat an eye.


  • Here’s the weird part though-

    Four in 10 hiring managers said they always contacted workers who applied for made-up jobs. Forty-five percent said they sometimes contacted those job seekers. Among companies that contacted applicants, 85% report interviewing the person.

    Does that part make sense to anyone?

    This strikes me less as fraud and more as a way to stay open to talent that you may not need immediately but still want to be able to add to your organization, in an era when basically nobody sends unsolicited resumes anymore. Like, maybe you don’t have a project in need of a Whatever Specialist right now, but it’s a field your company works in, and if a really exceptional Whatever Specialist is on the market, you don’t want to miss the opportunity to bring them on.




  • Federal authorities raided a home belonging to Oakland Mayor Sheng Thao early Thursday as part of a California investigation that included a search of at least two other houses, officials said… Agents also carried out searches about three miles to the south at two homes owned by members of the politically influential Duong family that owns the recycling company Cal Waste Solutions, the Chronicle said. The firm has been investigated over campaign contributions to Thao and other elected city officials, the local news outlet Oaklandside reported in 2020.







  • The play-by-email mode was broken to the point of uselessness in Civ5 and I don’t think they fixed in it in 6 (you had to have an always-on Windows desktop system running the server, and because the game logic was integrated into the graphics engine you couldn’t run it headless, and then on top of that there was basically no working system to coordinate active DLCs between players so most of the time people couldn’t join even if you did get the damn thing running) so my friends and I tried once and gave up. I would love for 7 to have a robust PBEM system so that we can play together without needing to spend hours a week watching paint dry while everybody else plots their turns, but I’m not holding my breath.




  • Courtesy of Roger Ailes and the invention of political talk radio, The United States was the breeding ground for media manipulation tactics that later arrived in Europe, and those have been most heavily utilized by right-wing actors – think Sky News/The Daily Mail/The Sun in the UK, or instance. When you poll most people about what they want out of government here in the US, they tend to be in alignment with “liberal” values in the US or center-left parties in Europe, but when you ask them if they support implementations of those values by name (i.e., “Social Security” or “Medicaid” or “food stamps” instead of just asking “should the government help needy people stay fed and healthy?” people who consume right-wing media suddenly flip to be against those policies, because they are brainwashed by their media diet to oppose them even though in principle they express support for them.

    Bottom line, after almost forty years of Rush Limbaugh and his ilk and thirty years of Fox News deliberately manipulating the American right to become hateful and reactionary in spite of their own natural impulses, the gap between left and right has become incredibly difficult to bridge in any meaningful way. IMO, the only hope for reconciliation is to push those extreme voices out of the mainstream in order to limit their ability to influence the gullible, and there’s just not many viable mechanisms to do that.


  • I’ve averaged about a 4 year tenure at my previous employers – some a bit more, some a bit less – but usually with a competing offer or two in that time period that I’ve used as a lever for a pay raise. Nobody’s complained about me being a job-hopper or short-timer.

    I have noticed that my two last employers, both large national firms, have moved towards a model of career-tracking with a defined pay structure, similar to government work where different positions and experience levels have a pay range attached to them and you’re not able to negotiate out of that range. This has been framed as a protective move against wage inequality suits, but I suspect it’s more about preventing employees from negotiating especially high compensation packages. I haven’t had it cut against me yet – in both cases I got a very minor pay bump when my employers actually went out and compared their pay scales to what the market was demanding – but if enough employers start benchmarking against each other and using that to cap pay, it will functionally become like a wage-fixing cartel similar to what’s happened to rent in the last 5-10 years.


  • Any time you see perovskite-based cells mentioned, you can assume for the time being that it’s just R&D. Perovskites are cool materials that open up a lot of neat possibilities, like cheaply inkjet-printing PV cells, but they have fundamental durability issues in the real world. When exposed to water, oxygen, and UV light, the perovskite crystals break down fairly rapidly.

    That’s not to say that the tech can’t be made to work – at least one lab team has developed cells with longevity similar to silicon PVs – but somebody’s going to have to come up with an approach that solves for performance, longevity, and manufacturability all at once, and that hasn’t happened yet. I imagine that when they do, that will be front-and-center in the press release, rather than just an efficiency metric.


  • North County was previously where all the middle class white people went after fleeing the urban core. Then as more African American families moved in to get away from urban decay, the white population moved to suburbs south and west of the city. This isn’t civil rights history, either – it’s been an ongoing process as recently as the 90s. My (white) dad grew up in Blackjack, just a short ways from Ferguson, and his parents only moved out of the area around 1995. When the unrest around Michael Brown’s death kicked off, he turned on the evening news to see the supermarket where my grandmother used to buy groceries going up in flames.




  • This is actually becoming somewhat commonplace. For example, in many cutting-edge cancer therapies, blood is drawn from the patient, processed in tissue-culture suites on site to extract the patient’s immune cells and sensitize them to some marker expressed by their specific cancer cells, and then the modified immune cells are returned to the patient room and transfused back into their bodies. It’s not cheap per se but it’s something that most top-tier cancer centers can do, and to do the similar process of extracting stem cells, inducing them to transform into pancreatic islet cells, and transplanting those into the patient’s pancreas isn’t that big of a jump – and it’d be cheaper than a lifetime of insulin in any case. It also points the way towards treating other kinds of organ failure without the risk of rejection, too.
