Как я писал in-memory векторный движок на Go — и в каком месте он обогнал hnswilb
Полгода назад я начал писать in-memory базу с векторным поиском на Go: RESP-протокол, HNSW-индекс, WAL, многопоточность. Рассказываю, что из этого вышло: как я мерил производительность и на каких граблях стоял, что реально ускоряет векторный поиск, а что нет. Все цифры воспроизводимы, код открыт.

Wenn du mit Java anfängst, stolperst du früher oder später über Begriffe wie H2, In-Memory-Datenbank oder SQLite. Auf den ersten Blick klingt das alles ähnlich. Irgendwie geht es um Datenbanken, oft um kleine Projekte, lokale Tests oder einfache Anwendungen. In der Praxis steckt dahinter aber n

rapeed: in-memory OLAP-движок с собственной алгеброй связей
Меня зовут Андрей Рыжик, я Product Owner BI-направления в компании «Белый код». Эта статья – обзор платформы rapeed: in-memory OLAP-движка с собственным форматом хранения, нестандартной алгеброй связей между источниками и несколькими клиентами поверх единого ядра.

Privacy-by-design: что наш edge не пишет на диск и почему это сложнее, чем кажется
Я пилю VantageDNS — рекурсивный DNS-резолвер с фильтрацией. NextDNS-clone, если коротко: юзер настраивает роутер на наш DoH endpoint, а мы рекурсивно резолвим и заодно режем рекламу, трекеры и malware. Privacy-фокус для такого продукта это не маркетинговая фича, а архитектурное ограничение, которое надо тащить с первого дня. Privacy policy без архитектурных гарантий — это обещание не лезть в твою тумбочку, ключи от которой ты сам отдал. В этой статье конкретика: что edge-нода не пишет на диск, как устроен кольцевой буфер для query log, что делать с crash dumps, и как юзер может проверить, что мы не врём, через strace . Что мы не пишем на диск

Разбираем net/http на практике. Часть 2.1: POST, файлы и in-memory хранилище
Предыдущая статья: https://habr.com/ru/articles/981356/ Продолжаем создавать сервис анонимных "мертвых ящиков" DeadDrop на чистом Go. Во второй части (первый подвыпуск) закладываем фундамент: учимся принимать POST-запросы, загружать файлы с проверкой MIME-типа и размера, создаём in-memory хранилище с потокобезопасным доступом через RWMutex. Пишем утилиты для генерации криптостойких ID и паролей. Разбираемся с интерфейсами и готовим архитектуру к дальнейшему развитию. Без фреймворков, только net/http и стандартная библиотека.

Пишем свою in-memory базу на Go, ускоряем поиск отелей в десятки раз
Если вы когда-либо строили высоконагруженные системы поиска, то знаете, что в какой-то момент узким местом становится не код, а сама архитектура. Поиск доступных отелей — как раз тот случай: миллиарды «ночей», десятки тысяч RPS, постоянные обновления календарей, строгая консистентность и высокая цена любой ошибки. Старый стек на Python + Postgres + Redis долго тянул, но однажды стал «тормозить» настолько, что оптимизировать дальше было невозможно — SQL-запросы разрастались, реплики множились, latency прыгала до 60 секунд, а кэширование превращалось в источник инцидентов. Так мы пришли к идее построить

I just heard that an old friend and colleague with whom I’d lost touch has died. There are lots of things to be said by people closer to them than I had become. But this person was kind, and classy, and creative. And by being all of that, they made the world, and so many other people’s lives, far better. If you know anyone like that, tell them so.

Packing up to leave for Virginia tomorrow. My brother’s sticker-covered cooler is the first thing going in the car — a small piece of him coming home with me, though I wish it were under different circumstances.

She was an Australian Shepherd with a huge heart and endless drive — my trail partner, mountain explorer, and most loyal friend.
From rocky summits to snowy valleys, she was always by my side, never asking for anything but the next adventure.

Felix has been physically gone for 33 years now, an amount of time that is almost impossible for me to believe. He’s been gone longer than he lived. And through all of those years, there is rarely a day that I do not think about him.

CW: Knitting update - sweater blocked
I’m not the best at repairing woollens - a cat claw hole? Yarn break? Not sure. I did not want to rip the front back that far to re-knit. Can definitely see where the hole was while it is wet. But, as it is it’s home-wearable, and probably less visible once dry and on. If it’s too noticeable then, I’ll add some dark embroidery foliage snaking up from the hem.
My first ever sweater done and blocked. 7 years (- thought 5, but nope, it was longer. Mum had gifted me the wool after my cancer revision op in ‘18. Glad it’s ready for wear on her birthday next month. 🌹
Clarke sweater pattern; awful, weak and oft broken Lana Grossa cashmere 16 wool - I might have just got a bad batch as the extra two balls I bought recently for the hems were much better.
