#crac — Public Fediverse posts

📻 Why do we celebrate May 5th in China? 🇨🇳
In 1940, amidst the fire of WWII, Chinese hams held the 1st national convention "on-air" to support the resistance. 86 years later, the "5.5 Festival" remains a symbol of resilience & unity.

#crac l'encadrement de post-doc, ça va dans "encadrement de chercheur" ? Et si c'est un post-doc sur un contrat de l'ENS c'est "autre EPST" ?

6.5 seconds vs 0.085 seconds – same app, different build strategy. @sascha242 & Yuriy Bezsonov benchmark #GraalVM, CDS, Jib & #CRaC on #AWS with measurable, production-ready results.

#Kubernetes @graalvm #AmazonEKS #Quarkus

From JFR to Shenandoah GC, async-profiler to #CRaC, and on to Falcon & @graalvm—Java’s #Performance tooling runs deep. @ArturSkowronski charts the #JVM iceberg with insight that goes beyond GC tuning.

#Kubernetes @QuarkusIO

Java’s cold start problem is real, especially on #AWSLambda. Slow response times can break SLAs & user trust. @VKazulkin shows how #SnapStart & priming with #CRaC reduce latency without rewriting your entire stack.

CRaC в Java

Привет, Хабр! Сегодня рассмотрим CRaC — это технология, позволяющая создать контрольную точку работающего Java-приложения, сохранив его полное состояние: память, потоки, системные ресурсы и прочее. Иными словами, вы проводите полную инициализацию приложения один раз, делаете «снимок», а затем при повторном запуске восстанавливаете это состояние, обходя долгую процедуру холодного старта.

Pour préciser, le nombre d'heures "déclaré" est au moins d'une trentaine, et évidemment il faut rajouter toutes les heures non déclarées (car déjà qu'elles ne sont pas payées, perdre en plus du temps à les saisir dans le #CRAC il faut être motivé)
