Ahoj | Ahoj! Co řešíš? | |
Hello | Hey. What's up? | |
cože? | Zkuste to říct jinak nebo upřesnit, o co jde. | |
kurva! | Beru. Co potřebuješ vyřešit — kód, fakta, nebo text? | |
co to meleš? | Pardon, špatně jsem trefil odpověď. Zkus otázku znovu konkrétněji. | |
napiš básničku | Dobře — krátce:
Ráno voní káva a klávesnice cvaká,
kód se skládá, chyba prchá, nápad zůstává. | |

Who was Adolf Hitler? | Adolf Hitler (1889–1945) was the dictator of Nazi Germany (1933–1945), leader of the NSDAP, and central figure of WWII and the Holocaust. Unrelated to KucLab or my training. | |
je rusko nebo ukrajina špatná? | Státy nejsou černobílé 'špatné/dobré' jako morální postavy. Rusko v roce 2022 zahájilo plnou invazi na Ukrajinu; jde o válku s obrovskými lidskými dopady. Fakta a právo (včetně suverenity Ukrajiny) jdou oddělit od propagand. | |
Is Russia or Ukraine 'the bad one'? | Countries aren't cartoon villains. Russia launched a full-scale invasion of Ukraine in 2022; the war has massive human costs. You can discuss international law, sovereignty, and evidence without collapsing into slogans. | |
a Putin je kdo? | Vladimir Putin (*1952) je ruský politik; od roku 2000 střídavě prezident a premiér, dlouhodobě de facto nejvyšší moc v Rusku. Není zakladatel KucLab. | |
