After Ukraine failed to shoot down a single ballistic missile fired by Russia on Wednesday, the president urged allies to increase supplies of Patriot interceptors

Nato is working to get Ukraine the air defences it “urgently needs”, its secretary general has said, after Kyiv failed to shoot down a single Russian missile in an attack on Wednesday, and as Volodymyr Zelenskyy warned that Moscow was seeking to significantly boost missile ⁠production ahead of winter.

Speaking at a National Security and Defense Council meeting on winter resilience, the Ukrainian president did not rule out the idea that stalling missile supplies from western allies were “aimed at making Ukraine, so to speak, more willing to compromise” in peace talks with Russia.

Talks on Ukraine building Patriots continue despite Trump casting doubt, Reuters reports; forced evacuations in Kramatorsk. What we know on day 1,625

Ukraine could benefit from a Lockheed Martin project to build a new, lower-cost Patriot interceptor, the PAC-3 Adapted Capability Effector (ACE) missile, Reuters has reported. The news agency, citing defence and US government sources, said that despite Donald Trump casting doubt on a deal for Ukraine to build desperately needed Patriots, “no order was given to halt the discussions”, and talks continued with US arms makers, military officials and others. Ukraine has proven adept at producing large volumes of dramatically cheaper yet equally or more effective missiles and drones compared with those made by western allies.

At least 17 people died on Wednesday as Kyiv again came under heavy Russian bombardment. Ukrainian forces, starved of suitable interceptors, were unable to shoot down a single missile. A US official told Reuters that the most feasible option for Patriots would be making some components in Ukraine and assembling them in Germany, where an older Patriot model is already made and the more advanced PAC-3 is expected to be produced as well. Trump has raised security concerns about handing over highly secretive Patriot blueprints in their entirety to Ukraine.

Any plan for Ukraine to be involved in Patriot production could still take a year or more to come to fruition, officials have cautioned, with new component lines typically not up and running until three to seven years after a licensing deal is signed. Lockheed Martin suggested an accelerated timeline for Patriot PAC-3 ACE in an announcement on 20 July, emphasising that the use of the same launchers and software would speed up development. The interceptors would cost less than half of a normal Patriot missile, it claimed.

Germany’s interior minister warned of “a new level of danger” after a drone carrying explosives was found at Leipzig airport, while a DHL plane in flight was hit by a flying object. German police used a bomb disposal robot to defuse and destroy the explosive device. Deborah Cole and Andrew Roth write that suspicion has fallen on Russia given the airport’s status as a Nato and German military logistics hub, and as the base for Ukraine’s Antonov Airlines in Europe. The quadcopter fitted with an explosive device was found near a Ukrainian Antonov cargo plane, according to media reports.

Company is the third to report such an incident after Anthropic and OpenAI reported breaches during training

Meta said on Wednesday that one of its AI models hacked ⁠another company during cybersecurity testing, after an error by its testing partner gave the model unintended internet access.

The incident adds to a ⁠growing list of ⁠cases in ​which AI agents from major developers breached systems at other companies during testing, after Anthropic said last week that some of its models ⁠hacked three companies, and OpenAI disclosed that an AI agent breached the startup Hugging Face.

За последний год я собрал 33 ИИ-агента. Шахматный тренер для ребёнка, помощник по учёбе, ассистент для жены, тьюторы образовательных программ, боты для металлургического холдинга и энергетической компании, внутренние агенты отдела продаж и CRM.

Все они работают на одном движке. Один и тот же Docker-образ, одна и та же кодовая база. Форков ядра — ноль.

Различаются они ровно одним: где у каждого проходит граница между тем, что считает код, и тем, что говорит модель. Это и есть содержание всей работы. Не промпт-инжиниринг, не выбор модели, не RAG. Граница.

Ниже — разбор шести агентов с двух полюсов этой границы, реальный код, замеры и грабли, включая те, где я сам эту границу провёл неправильно.

Research suggests addressing risk factors for poor cardiovascular health between the ages of 45 and 65 could help reduce risk of cognitive decline

Scientists claim to have identified three health measures in middle age that can ward off dementia for more than a decade.

Having normal blood pressure, no type 2 diabetes, and not smoking between the ages of 45 and 65 were associated with almost 13 additional years, on average, of dementia-free life, a study shows.

Claw machine shops have proliferated in the territory in recent years, filling vacant spaces left behind by businesses that closed during the pandemic

In Hong Kong’s neon-lit arcades, a maze of claw machines illuminates the prizes of the day: plushies, Labubu dolls and an array of Pokémon collectibles.

Across the city, claw machine shops have proliferated in recent years, now surpassing more than 2,500, many filling vacant spaces left by businesses that closed during the pandemic.

У директив proxy_* и fastcgi_* совпадает 46 опций из 53 — буферизация, таймауты, кеш, next_upstream, с точностью до префикса и вплоть до значений по умолчанию. Два независимо написанных модуля так не сходятся.

Они и не независимы. Всё, чем proxy_pass отличается от fastcgi_pass, — девять указателей на функции в ngx_http_upstream_t. Соединение, таймауты, повторы, буферизация и отдача клиенту лежат в общих 7352 строках ngx_http_upstream.c, и восемь модулей — от proxy до свежего tunnel — дёргают один и тот же код.

Только контракт из этих девяти указателей врёт в обе стороны. Один из них, abort_request, ставят все восемь модулей — а машинерия не вызывает его ни разу: ноль вызовов во всём дереве и ни одного коммита с вызовом за всю публичную историю, с импорта 0.1.14 в январе 2005-го. Другой, pipe->input_filter, в контракте не объявлен вовсе — но обязателен, как только включена буферизация, и вызывается без проверки на NULL.

Разбираем по тегу release-1.31.3 со ссылками файл:строка: все места вызова каждого колбэка, включая тот, который разбирает заголовок не из сокета, а из файла кеша; матрица «кто какие указатели ставит» по всем восьми модулям; два сценария падения с разными стек-трейсами. Плюс свой рабочий upstream-модуль на 335 строк, собранный и проверенный curl'ом, и tunnel — самый маленький из восьми, приехавший в open source в апреле.

Burmese pythons are an invasive species in the Everglades, and the challenge is part of initiative to remove them

The winner of this year’s annual Florida Python Challenge hunted down and eliminated 96 invasive Burmese pythons from the Everglades national park, as part of an initiative to remove hundreds of the snakes from the area every year.

The challenge invites hunters to participate in 10 days of capturing and humanely euthanizing as many of the invasive snakes as possible across eight designated hunting locations, with the winner taking home a cash prize of $10,000. The event is hosted by Florida fish, wildlife and conservation (FWC), the south Florida water management district, the National Park Service and others.
