Why is twitter not blue anymore? It looks like threads. Ugly.

Would you rather drink one beer every evening for a year, or drink 365 beers in one evening? All of nuclear power 'safety' regulation is built on the idea that, when the same question comes to radiation, there's no difference. But the empirical evidence is overwhelming that the body repairs small amounts of damage caused by ionising radiation in the same way it repairs damage from other small harms. If this is correct it would mean that the "unsafe at any dose" philosophy that has underpinned the regulation of nuclear energy since the 1970s is wrong. It is premature to conclude that yet: we need more evidence. But if that further research does confirm what the existing evidence suggests, then nuclear power is much, much more expensive than it needs to be, even in places like South Korea that build cheaply, and nuclear power could be cheaper than any other form of electricity. We could go much further than, say, the Fingleton Review or the mainstream proposals for reform that are on the table in the United States. We could have a new atomic age in which the "too cheap to meter" dream was realised.

Would you rather be exposed to the radiation of 1,000 CT scans all in one go, or be hit with the same cumulative amount of radiation, but over the course of a lifetime? worksinprogress.co/issue/how-to-l… Hopefully you will not have to take that decision, but if you do, make sure it's spread out over your lifetime. There is now overwhelming evidence that low-dose-rate ionizing radiation is not that harmful. Even Chernobyl, by far the world's worst nuclear disaster, exposed millions yet has likely killed 60 or so people. A total of 200 may die early. The other bad civil nuclear disasters – Windscale, Fukushima, and Three Mile Island – likely killed nobody at all. The evidence is rolling in: ---> Many residents of Kerala are exposed to seven full-body CT scans' worth of ionizing radiation every year. But multiple studies find no effect on their health. ---> Taiwanese apartment dwellers were unwittingly exposed to up 100 CT scans per year because their apartments were made with radioactive cobalt rebar. But dwellers suffered much lower cancer rates than other age-comparable Taiwanese. ---> Between 1915 and 1950, women in factories painted radium onto watch dials to make them glow in the dark. Those licking the brushes sometimes suffered severe cancers. But non-lickers had lifetime doses equivalent to nearly 1,000 CT scans with no effect. ---> At 58 in 1945, Albert Stevens was injected with an enormous amount of plutonium, exposing him to a radiation dose equivalent to 300 CT scans every year. He lived to be 79. These and many other studies show that ionizing radiation's harms are primarily about concentrated acute doses, not low doses over a long time. Yet nuclear regulatory systems are based around the principle that any radiation exposure is totally intolerable. This leads to rules like 'ALARA' – as low as reasonably achievable – which continually ratchet up regulatory requirements, making nuclear power slow and expensive.

WSL1 was one of Microsoft's most ambitious kernel projects: Linux binaries running on NT without a Linux kernel. "lxcore.sys" translated Linux syscalls into NT kernel operations on the fly. WSL2 took the pragmatic route and runs a real Linux kernel in a lightweight VM. OpenLxCore is reverse-engineering and recreating the WSL1 compatibility layer, exposing the magic that made Linux-on-NT possible.

It’s 2018 and your coworker just sent you a 400 line pull request. You get a cup of coffee and sit down to review it. It’s beautiful. Elegant micro-refactors. Crispy method names. You catch a few things, but that’s ok. It’s part of the dance. They didn’t consider extensibility on part of their API. Here’s a comment buddy. They respond in an hour saying they think we should do one piece differently than your comment. Hey let’s jump into a room and figure it out. We can’t just agree to disagree, this code is too important. The PR merges and goes to prod. You feel a shared sense of ownership and accomplishment. That night you go to sleep and dream of that code. You can still see the shapes of it on the backs of your eyelids, your IDE syntax highlighting sparking neurons in your reptile brain. You go to work the next day ready to go. You understand the system. N is your foundation. Time to build n+1.

IMHO, the loss of Twitter/X as a platform where virtually everyone in infosec who was publicly active online had a presence has really been deleterious to a lot of info sharing. It's also no doubt prevented a lot of useful discussions and interactions from happening.
