We have been working for many months to answer this customer ask. Within weeks, AWS will deliver a new public container registry that will allow developers to share and deploy container images publicly. This new registry will allow developers to store, manage, share, and deploy container images for anyone to discover and download. Developers will be able to use AWS to host both their private and public container images, eliminating the need to use different public websites and registries.

IPv6 Is a Total Nightmare — This is Why

So this is just going to be a total rant. IPv6 is, in theory, a solution to many things, including the dwindling IPv4 address space. IPv6 was officially a draft in 1997, and became a real Internet Standard in 2017. And, quite frankly, it's one of those things…

Всем привет!
Провели воркшоп на гейзенбаге по тестированию производительности с gatling и gitlab, для воркшопа подготовлено множество материалов, которые могут помочь в самостоятельном изучении этих инструментов.
Все материалы доступны в публичном репозитории: https://gitlab.com/tinkoffperfworkshop
Первую часть воркшопа можно повторить самостоятельно по шагам из шпаргалки: https://gitlab.com/tinkoffperfworkshop/part-1/cheat-sheet
Во второй части созданы отдельные репозитории, в них также есть ридми с инструкциями: https://gitlab.com/tinkoffperfworkshop/part-2

Что есть интересного:
1. Разворачиваем окружение для тестов локально в контейнерах: influxdb, vector, loki, prometheus, cadvisor, portainer, grafana, gitlab-runner
2. Создаем скрипты gatling для различных протоколов: http, jdbc, grpc
3. Создаем CI джобы для gitlab
4. Подключаем агент в gitlab.com
5. Проводим и мониторим тесты

Make JSON greppable!

gron transforms JSON into discrete assignments to make it easier to grep for what you want and see the absolute 'path' to it. It eases the exploration of APIs that return large blobs of JSON but have terrible documentation.
