"A 2018 study in Beijing, China suggests that smog masks with filtration equivalent to N95, KN95, or FFP2 were most effective for filtering PM2.5 and diesel soot (4).

Wearing air quality masks has also been proven effective for reducing transmission of airborne COVID-19."

PM2.5 is bad, folks.

Hazy orange sun this morning, and the notes of ozone in the air.

#AQI in Toronto still good today, but a good cue to change the furnace filter and find the N95's. #PM2.5 around 10 outdoors.

My thoughts with Canadians in #Manitoba and #Saskatchewan dealing with the real problems of these #forestfires.

RustDesk: удалённый десктоп через свой сервер ретрансляции

RustDesk — приложение для удалённого рабочего стола с открытым исходным кодом, разработанное для самохостинга в качестве альтернативы TeamViewer. Название такое, потому что программа написана на Rust. Работает из коробки, не требует конфигурации. Если установить сервер синхронизации на своём хостинге, то любые машины в интернете могут синхронизироваться и устанавливать соединение через наш сервер для удалённого управления рабочими столами друг друга. Трафик идёт напрямую между ними, но если это невозможно — тоже через сервер, до 3 Мбит/с (1920×1080). Клиентское приложение есть для iOS и Android (на КДПВ), что позволяет со смартфона управлять рабочим столом Windows, Linux и MacOS (и наоборот), а также обмениваться файлами. Есть ещё веб-клиент .

Многопоточность в NextJS: как запустить и нужно ли?

На определённом этапе своей карьеры я задался вопросом: может ли Next.js работать в многопоточном режиме? Оказалось, что нет. Это побудило меня разобраться, как можно организовать многопоточную работу Next.js и насколько это оправдано для сайтов с высокой нагрузкой.

Деплоим Next.js приложение через PM2

Недавно мне посчастливилось развернуть Next.js на сервере с помощью PM2. Этот способ я не нашел в документации фреймворка, хотя считаю его довольно удобным, при этом гайдов по теме оказалось очень мало. Рассказываю, как всё сделать, и привожу рабочие примеры.

How #AirPollution is causing girls to get their first #periods earlier

New research shows that girls in the US are getting their first periods earlier. Exposure to toxic air is partly to blame.

By David Cox, June 4, 2024

"The same trend has also been noted around the world. South Korean scientists have described with some alarm how the number of girls displaying signs of precocious puberty – either breast development or #menstruation before the age of eight - increased 16-fold between 2008 and 2020.

"We're also seeing that these decreasing ages at puberty are even more pronounced in lower socioeconomic status groups, and ethnic minority groups," says Audrey Gaskins, an associate professor at Emory University in Atlanta, the US. "This has important implications for long-term health."

Researchers like Gaskins are primarily concerned that beginning puberty earlier might trigger a cascade of events which have far-reaching consequences later in adulthood. Emerging data suggests that it may not only curtail the fertility window, particularly if these women then enter menopause sooner, but shorten their lives. Precocious puberty has been repeatedly associated with a higher risk of diseases ranging from breast and ovarian cancers, metabolic syndromes such as obesity and type 2 diabetes, and cardiovascular disease."

"For several decades, scientists around the world have become increasingly concerned by signs that girls are entering puberty at a much younger age compared with previous generations.

From when girls experience their first period, something which scientists term the age of menarche, to commencing breast development, these seminal changes marking the onset of adolescence appear to be taking place progressively sooner.

"American girls today have been estimated to start menstruation up to four years earlier compared to girls living a century ago. In May, new data showed that while girls born between 1950 and 1969 typically began menstruating at 12.5 years, this decreased to an average of 11.9 years for the generation born in the early 2000s.

"The same trend has also been noted around the world. South Korean scientists have described with some alarm how the number of girls displaying signs of precocious puberty – either breast development or menstruation before the age of eight - increased 16-fold between 2008 and 2020.

"Some of the major culprits appear to be #ToxicGases such as #SulphurDioxide, #NitrogenDioxide, #CarbonMonoxide and #ozone, all of which are released into the air either through #VehicleEmissions or waste produced by #Manufacturing Plants. In 2022, a study from scientists in Poland, a country known for its poor air quality due to the prevalence of #coal-burning factories, examined data from 1,257 women, and found a link between greater exposure to nitrogen gases and menstruation occurring before the age of 11."
