La veille du séisme en Birmanie, le satellite #Sentinel-1A avait pris une image radar de la région. Quelques jours plus tard, Sentinel-1C en a repris une. Les 2 images combinées forment un interférogramme de la faille de Sagaing.

#Drought, Lake #Constance and #Sentinel-2: Switzerland has experienced an exceptionally dry period, with Lake Constance’s water levels dropping to their lowest in decades due to little rainfall and snowmelt from the Alps. Recent Sentinel-2 #earthobservation / #remotesensing data and gauging station records reveal...

Кнопка «F5» устала: real-time уведомления в микросервисной архитектуре
Представьте себе: у вас железнодорожная станция, сотни вагонов, десятки пользователей в системе, каждый раз кто-то нажимает кнопку "Обновить", чтобы узнать — разгрузили ли нужный вагон. Вся логика обновления построена на "manual refresh". Да-да, пользователь сам жмёт кнопку, чтобы получить свежие данные. Система автоматической разгрузки или другой человек разгрузил что-то на другом конце станции, но вы об этом не узнаете, пока не перезагрузите страницу. А ещё — избыток HTTP-запросов, polling, перегруженные серверы и полное отсутствие real-time взаимодействия. Есть вариант! Масштабируемая и отказоустойчивая архитектура с использованием Redis Sentinel + Pub/Sub + WebSocket/SSE . В статье расскажем какие проблемы возникают с real-time в Kubernetes, почему стандартные WebSocket-подходы не работают при нескольких подах, как построить отказоустойчивую систему с Redis Sentinel, как сделать real-time UI, сохранив отказоустойчивость и масштабируемость, и как всё это запустить локально для отладки. 
Разбираем решение!
Bonjour tous,
L'info à déjà circulée mais je viens de lire le communiqué du #cnll et je trouve qu'il mérite d'être bien largement diffusé :
https://cnll.fr/news/polytechnique-men-office-365/
Des structures comme #anticor ou #Sentinel pourraient peut être aider à porter l'affaier en justice, non ?
You can call yourself a "thrill seeker" if you want, but I do feel the world is becoming increasingly blasé about keeping within the law. Stories (not related to this article) about the police misbehaving probably don't help things though ... #Sentinel #influencers

Transition to enhanced modeling of Threat Intelligence data in Microsoft #Sentinel by 31 July 2025
That's a tight schedule, better get started soon.

HIGHLIGHTS:
• Proposed U-ViT model based on Prithvi GFM for multi-sensor glacial lake mapping.
• Achieved an F1 score of 0.894 on Sentinel-1&2, surpassing CNNs scoring below 0.8.
• Maintains strong performance with 50% less training data, proving efficiency.
• Excels in detecting small lakes (<0.01km²) and handling clouds and complex terrains..."

Have you seen 𝐒𝐞𝐧𝐭𝐢𝐕𝐢𝐬𝐭𝐚 already?
It shows great examples of #Sentinel Data applications
and nice 3D models of the satellites
