Design Pattern sind wiederkehrende Lösungen für häufig auftretende Probleme in der Softwareentwicklung. Sie sind kein fester Code, den man kopiert und einfügt, sondern eher ein Bauplan oder eine bewährte Idee, wie man ein bestimmtes Problem sauber, verst...

Tech billionaires are leveraging tens of millions of dollars
to influence California politics
in a marked uptick from their previous participation in affairs at the state capitol.

Behemoths such as #Google and #Meta are getting involved in campaigns for November’s elections,
as are venture capitalists, cryptocurrency entrepreneurs and #Palantir’s co-founders.

The industry’s goals run the gamut
– from fighting a billionaire tax
to supporting a techie gubernatorial candidate
to firing up new, influential super political action committees (Pacs).

The phenomenon squarely fits the moment for the state’s politics
– with 2026 being the year that Politico has dubbed
“the big tech flex”.

Gavin #Newsom, California’s tech-friendly governor
who’s been quick to veto legislation that cramps the sector’s unfettered growth,
is reaching his term limit.

That means Silicon Valley needs to find a new ally.
The industry may have found its candidate in an upstart mayor from San Jose, ⚠️Matt Mahan.

Silicon Valley’s businesses and billionaires
– some of the richest and most powerful on earth, most of which are headquartered in California
– are in the midst of a massive AI boom.
Industry insiders say tech companies need to ensure they can continue to flourish without regulations getting in the way.

“This is a golden opportunity and a golden moment for tech to reset its priorities and its perceptions,”
said David McCuan, a political science professor at Sonoma State University who studies state lobbying.

Rather than going all-in on one candidate or issue, McCuan said the tech sector is using a multi-pronged attack in California.
Tech billionaires are contributing to campaigns ranging from candidates for governor
to local city council and school board races.

They are also donating heavily to groups campaigning for relaxed taxation and minimal regulation around AI.

“If you’re an uber-zillionaire, you give money early and often,” McCuan said.
“They have more wealth and resources than they’ve ever had before,
so that allows them to play on both sides of the aisle and up and down the ballot and across issues like never before.”

Unlike other industries, such as oil and pharma, tech has been relatively tame when it comes to lobbying in the state.
The industry has tended to focus on narrow state issues and instead spent big and broad at the federal level
(aside from Uber and Lyft’s massive $200m ballot measure campaign in 2020).

That ethos has changed.
California is now ground zero for tech titans working to become omnipresent in politics.

Robert #Singleton,
the senior director of policy in California for the tech industry group "Chamber of Progress",
said this moment has been brewing for a long time and it just needed the right thing to set it off.

“The introduction of that #billionaire #tax obviously galvanized a lot of wealthy individuals who don’t want to see that happen,
and who will spend money to make sure it doesn’t happen,”
Singleton said.

“That tipped them into wanting to get more involved.”

Python и паттерны GoF, часть 1: Singleton

Недавно мне в очередной раз довелось читать молодым коллегам курс по языку Python. По самому языку мы прошлись и начали говорить о паттернах проектирования и их реализации. В итоге захотелось мне превратить материалы курса в несколько статей. Это первая. Статья получилась большая, сначала я планировал рассказать в одном тексте обо всех порождающих паттернах, но, поглядев на размер, передумал и разбил историю на части. Первым паттерном, который мы рассмотрим, разумеется, станет синглетон. Как только его по-русски не называют, кстати. Синглтон. Синглетон. Наконец, ОДИНОЧКА. Не, ну вы представляете, ОДИНОЧКА?! Покажите мне живого человека, который так говорит? Я ни одного за 30 лет использования паттернов GoF не видел. Казалось бы, что о нём можно сказать разумного, доброго, вечного, а главное — нового? Паттерн довольно тривиальный, всего лишь способ создать объект класса, который нельзя инстанцировать более одного раза, а потом использовать этот объект везде, где нужно (часто в совсем разных местах). И довольно спорный во многих случаях. Особенно в Python, где я обычно не советую его использовать так, как в C++.

Guinée : le chanteur Singleton jugé pour "homicide involontaire" • FRANCE 24

I was sitiing in traffic doing the #Singleton #Crawl (IYKYK) and looking at a late 60's Pony burbling away in front of me.

Two things struck me as different between old cars and new.

The rear windscreen was huge.
The car had no headrests on the seats.

How times have changed.
