Приветствую, уважаемые читатели.

Ранее я публиковал на Хабре статью «Пещерные астронавты. Предыстория освоения внеземных лавовых трубок». Будет удивительно, если и освоение Марса начнётся с пещерного века, уже пережитого нашими предками на Земле. Впоследствии эта тема натолкнула меня на поиски и находки, подсказывающие, что современные города неплохо приспособлены к подземному расширению, и дело не ограничивается разветвлёнными хорошо проветриваемыми метрополитенами. Примерно с начала XXI века разрабатываются дизайнерские, полуфантастические и вполне утилитарные проекты подземных городов, а первые образцы «человеческих муравейников» известны со времён расцвета Византийской империи. Ниже расскажу о некоторых общих чертах современной подземной урбанистики, основным двигателем развития которой сейчас стали глобальные изменения климата.

Слышали про Effect — One-Time Events? Когда я о нём узнал — сразу стал использовать этот паттерн в своих ViewModel, дополнительно избавляясь от error: String? и подобных в моём стейте.

Однако я столкнулся с тем, что реализовать паттерн Effect можно по-разному. Давайте кратко обсудим каждый способ и выберем самый лучший для вашего проекта!

Donald Trump may reject the negotiations, but he cannot veto a global effort to make multinational companies answer to governments

Governments are told that public services must shrink because money is tight. Yet a new Tax Justice Network report says that countries could capture an extra $500bn a year without raising corporate tax rates. The answer is to tax multinational profits where real economic activity happens – known as unitary taxation. No new profit is created. Revenue simply shifts from tax havens where profits are “booked” to the countries where workers produce and customers spend.

Making that principle a global tax standard depends on UN talks opening in New York on Monday. Modelled on the UN climate regime, a fiscal framework convention would create the governing body and procedures, with protocols providing detailed rules. The UN wants agreement by late 2027. Donald Trump’s US walked out last year and urged others to follow. None did.

Water is a vital shared resource, and privatisation has made a just transition harder

Compared with rising heat-related deaths, and devastating wildfires in the Cairngorms and Suffolk, the announcement that the Royal Horticultural Society (RHS) is considering moving its hydrangea collection from Surrey to Greater Manchester and North Yorkshire might seem unimportant. But it points to geographical differences in exposure to global heating that have arguably never been more evident than this summer, with last month the driest on record. Seven areas of south and east England are officially in drought, along with the whole of Wales.

A drought is less easily measured than a heatwave, which is declared by the Met Office when the maximum temperature exceeds a set threshold on three consecutive days. But the fact that drought is harder to quantify does not make it less damaging. Water shortages are exposing specific vulnerabilities and inequalities, as well as the UK’s lack of preparedness for climate change overall.

Royal Albert Hall, London
An acted prelude by Jane Mitchell teased out the composer’s motivations for his engrossing First Symphony before the orchestra assayed the work from memory

“Ridiculous,” “offensively trivial”, “a complete disaster,” just some of the critical barbs hurled at Gustav Mahler’s First Symphony following its Budapest premiere in 1889. A babel of such invective echoed around the Albert Hall launching the ingenious theatrical presentation – in effect, a staged programme note – that preceded Aurora Orchestra’s performance of the work in all its maverick majesty. Over an hour, actors and musicians took us on a light touch, deep dive into the circumstances surrounding the genesis of a symphony that frankly baffled its first audience.

“For those that listen closely, everything about me is explained in this music,” declared a beguiling Jack Bardoe, perfectly encapsulating Mahler’s combination of frenetic energy and artistic neuroses (“A bomb encased in razorblades,” is how one-time friend Ferdinand Pfohl put it). The setting was a psychiatrist’s office, with Sarah Twomey a forthright Sigmund Freud (“Tell me about your mother”) linking the composer’s compulsion to write music with a need to re-enact childhood trauma. Paternal cruelty, eight siblings lost in infancy and a disastrous love affair fostered a deeper understanding of what made Mahler tick.

Menstrual and digestive discomfort often coincide, and a researcher who has been looking in to it for a decade tells us what she learned

Every period, right on schedule: the cramps arrive, and right behind them, the urgent need to poop.

If this is your experience, you’re in good company: in one study, 73% of healthy premenopausal women reported at least one significant gastrointestinal symptom in the days before or during their period. Abdominal pain and diarrhea were the most common complaints, but women reported nausea and constipation too.

Farmers battle to salvage what they can of their crops as heatwave set to continue

Britain could face shortages of certain foods after punishing drought in parts of England, the National Farmers’ Union (NFU) has warned as a heatwave was forecast to continue into next week.

The UK’s Health Security Agency (UKHSA) has issued heat health alerts for eight regions of England, with temperatures set to rise above 30C in parts of the country. UKHSA said rising temperatures may increase health risks, particularly for vulnerable groups.

Farms and rooftop panels contribute 14.4% to the grid – and figures reveal a surge in new installations

Solar energy supplied more power to Great Britain’s grid in July than in any previous month as households turned to rooftop panels to cut their energy bills.

Solar farms and rooftop panels provided 14.4% of the country’s electricity after some parts of the UK recorded almost twice the average sunshine hours for the time of year.
