The agreement gives American companies priority access to nuclear reactors and fuel to Saudi Arabia. It's expected to last decades and be worth billions of dollars.

Закон Мура, похоже, задвинули, т.к. упоминается он все реже и реже. А вот закон Амдала нет-нет, да вспомним. Тем более, что он приведен чуть ли не в каждой книге по параллельному программированию. А, ведь, есть и другие законы типа закона Гроша или гипотезы Минского. Но подобный их статус обязывает ко многому. Однако после детального знакомства с ними это ощущение, как правило, теряется.

В законе Амдала, вроде, все правильно, но что-то не так и не то. Подобные сомнения возникли почти сразу после знакомства с ним. Но, правда, кто я такой, чтобы давать оценку? Да и интересовали меня на тот момент другие проблемы, к которым данный закон имел, как мне представлялось, косвенное отношение.

Однако, «давно не было такого и вот опять» – свежая статья на Хабре про закон Амдала, да еще и с настоятельной рекомендацией его изучать[1]. Пришло, видимо, время мне на эту тему высказаться. Хотя бы в пику его «обязательности чтения», т.к. для тех, кто «проектирует параллельные системы», подобные советы представляются не только излишними, а даже вредными.  

Все это, конечно, с «высоты» нынешних моих позиций. За прошедшее время они стали более строгими. Но все же это только моя личная оценка, но опирающаяся на мой опыт и на общепризнанные научные представления о процессах распараллеливания «реальных задач».

Так давайте попробуем понять кто прав, а кто нет.  А поможет нам математика, которую можно не понимать, можно даже не любить, но не уважать нельзя.

Shares in Elon Musk company fall more 3% in after-hours trading, as earnings per share miss Wall Street expectations

Tesla reported its second-quarter earnings on Wednesday, disclosing far lower profits than expected. The company’s already beleaguered stock, which had fallen about 14% this year to date, dipped further following the earnings report.

Elon Musk’s automaker, once the pinnacle of his tech empire, has taken a back seat to SpaceX. Musk’s rocket and AI company held the largest stock market debut in history last month, turning the richest man on Earth into the world’s first trillionaire, though his net worth has since fallen from its peak.

Three-year-old girl landed in ICU after snake bit her while grabbing a package outside her family’s Santa Clarita home

A three-year-old girl landed in the intensive care unit earlier this month after a rattlesnake bit her while she was trying to grab an Amazon package.

Addy, the young girl, ran out with her mother on 13 July to pick up a package dropped over the gate to their home in Santa Clarita, north of Los Angeles.

GOP-controlled chamber paves way for reconciliation bill, while making long-shot attempt at new voting restrictions

House Republicans on Wednesday agreed to begin the process of writing a $95bn bill to fund the war with Iran as well as provide new aid to farmers, while making a long-shot attempt to impose new restrictions on voting nationwide.

In a virtually party-line 216-214, the Republican-controlled chamber passed a budget resolution that paves the way for the creation of a reconciliation bill, which can advance through the Senate under special rules that circumvent the Democratic filibuster and requires only a simple majority to pass. Two Republicans – Warren Davidson of Ohio and Thomas Massie of Kentucky, as well as Kevin Kiley, an independent of California who aligns with the GOP – joined all Democrats in opposing the measure.

Hacking of Hugging Face shows we do not seem to have reliable ways to curb extremely powerful AI systems

Last week Hugging Face – a company that hosts artificial intelligence models and datasets – was hacked.

After it reported the incident to law enforcement, few would have predicted what came next: the culprits were revealed to be AI agents from OpenAI, which had broken out of containment and were acting of their own accord.

The Saudi deal stoked surprise and immediate concern across Washington, as well as in Israel, itself a nuclear power that has long feared an atomic arms race could grip the region.

Passage of annual bill complicated by Trump’s decision to join Israel in attacking Iran without congressional approval

The US House of Representatives passed a $1.15tn defense policy bill in a near-party-line vote on Wednesday, after Democrats refused to back the measure amid the war with Iran and Donald Trump’s push to impose new restrictions on voting nationwide.

A key plank of the president’s plan to spend $1.5tn on the military in the 2027 fiscal year, the National Defense Authorization Act (NDAA), passed the Republican-controlled chamber by a 216-212 vote, with all but six Democrats opposing its passage. Seven House Republicans broke ranks to oppose it. The measure now goes to the Senate.

• Former Hearts coach railed at ‘disgusting’ VAR decision

• SFA punishment means ban for start of new season

Derek McInnes, the new Rangers manager, is poised to begin the season in the stands after being handed a four-match ban for his comments on Celtic’s controversial penalty at Motherwell last season.

The then-Hearts manager described the VAR decision to give Celtic a stoppage-time spot-kick – which proved crucial in the Scottish Premiership title race – as “disgusting”. On Wednesday the Scottish Football Association announced McInnes would receive a four-match ban, with one game suspended until the end of the season.

• Richard Boardman was criticised by the managing judge

• Players want ‘firm with resources and specialist expertise’

Hundreds of former rugby league and rugby union players taking legal action against the game’s governing bodies are now “staring into the precipice”, according to the barrister representing the claimants, Susan Rodway KC.

Richard Boardman, the solicitor who has been the organising force behind the litigation, has requested formally to come off the record after his handling of the case was criticised by the managing judge, Senior Master Cook. The case may now be taken over by Leigh Day, who has been working on it as consultants since February.

Self-reported domestic violence incidents declining in NSW but deaths and hospitalisations fail to fall

New data shows self-reported domestic violence incidents in New South Wales have declined, but the number of women and children murdered or hospitalised in domestic and family violence incidents over the past eight years has not significantly budged.

The decline in self-reported violence is significant because it reflects underlying levels of violence in the community, not just what is reported to police. It suggests that, despite rising reports of domestic violence to police, domestic violence in the community is not increasing and may be trending down.

There’s a strong perception that violence against women is rising, which is understandable given increases in police-recorded incidents, heightened media attention and greater public awareness.
