Modern LLMs (GPT-5.1, Claude 4.5, Gemini 3) produce excellent code and can be a significant productivity boost to software engineers who take the time to learn how to effectively apply them - especially if used with coding agent tools

Polární záře by letos v zimě mohla předvést nejpůsobivější podívanou za více než deset let. Sluneční aktivita totiž dosahuje svého vrcholu, informuje server EuroNews. irozhl.as/yfs
Letošní zima slibuje nejúchvatnější pohled na polární záři za desetiletí. Turisté míří do Skandinávie
Slunce vstupuje do maximální fáze svého jedenáctiletého cyklu, během níž se zvyšuje aktivita slunce a tedy i šance pozorovat polární záři. Ta se stala vyhledávaným turistickým cílem.

GovTech doesn't have a Wikipedia entry.
Search for it. You'll find a magazine and Singapore's government tech agency. But no article defining GovTech as a field.
That absence is the entire story. 🧵

Slovensko si zakázalo ústavou mj. také lhát a pomlouvat. Gratulky. www.irozhlas.cz/zpravy-svet/...
Slovensko přidá do ústavy konzervativní hodnoty. Nově oficiálně uzná jen pohlaví muže a ženy
Výhrady vůči předloze dříve vyslovili odborníci na ústavní právo Rady Evropy, jakož i právní experti na Slovensku. Premiér Robert Fico ústavní změny dříve označil za hráz proti progresivismu.

There’s a persistent myth that new solar farms don’t really help tackle climate change because panels are “made with coal” and “never pay back” their carbon debt.
This is simply false.
- UN: solar ~8x cleaner than gas, ~19x than coal per kWh
- panels repay CO2 in 4 months; save 57x over life

Bulgaria, the euro is coming!
On 1 January 2026, Bulgaria will become our 21st Eurozone country.
This means more than just a new currency – it is a real achievement.
The euro will strengthen Bulgaria’s economy and bring big benefits for Bulgarian people and businesses.

This is a new Murderbot short story, coming out later this week on Reactor Magazine. It’s about ART and its crew, set before Network Effect, and how ART finally decided to tell them about meeting a rogue SecUnit.

With Mount Fuji’s official climbing season starting today, I spoke with police and other mountain rescue experts about the dangers of hiking Japan’s highest and most iconic peak. www.japantimes.co.jp/news/2025/06...
What it takes to save lives on Mount Fuji
Mount Fuji’s deadliest weekend still echoes today. Luckily, area rescue squads have leveled up their game.

Snad bude začátkem října ještě venku dostatečné horko, aby si voliči uvědomili, že potřebují volit takové politické strany, které jsou schopny omezit lidský vliv na globální oteplování. A ne dinosaury, co jen kecají o spalovacích motorech.
