Падающая сборка, и это я её просил

Три способа тихо сломать приложение сборкой зависимостей: два пула к базе, не тот кэш, разъехавшиеся ветки конфигурации. Компилятор их не ловит — типы верные. Рантайм-контейнеры ловят половину и приносят свои отказы. Про diogen — compile-time DI для Go: внедрение зависимостей на этапе компиляции, обычный Go-код на выходе, без рантайм-контейнера и без рефлексии.

Валидатор не нашёл поле is_admin, а Go его нашёл: пять ошибок при работе с JSON

Один и тот же JSON может привести систему к разным выводам. Валидатор пропустит поле, которое Go‑сервис спокойно прочитает, nil ‑слайс превратится в неожиданный для клиента null , а ошибка в имени параметра останется незамеченной до самого продакшена. Разбираем пять случаев, где поведение encoding/json в Go способно создать расхождение между компонентами системы, и смотрим, что меняет переход на encoding/json/v2 . Узнать детали

Most guides I found on Go backend services cover the code inside the service, with little on the production problems around it: configuration, lifecycle, observability, packaging, deployment.
My new guide, Building a Production REST API in Go, covers all of these alongside a working example service: https://tecnick.com/guides/go-rest-api/

Hey #golang folks, I have a service listening on some port (say 4321) and the #systemd service file has
```
SocketBindAllow=tcp:4321
SocketBindDeny=any
```

When my service makes an _outgoing_ connection by calling
```
var dialer net.Dialer
dialer.DialContext(ctx, "tcp", "somehost.example.com:5678")
```
the service gets a permission error for violating the SocketBind* systemd restrictions.

But only when using the cgo resolver. Setting `GODEBUG=netdns=go` fixes the error. So what is the cgo resolver doing that requires binding a socket?

WGX is now ihasvpn, and it's been rewritten from scratch.

The old WGX was a Bash installer that assembled a VPN on your host. The new one is a WireGuard server of its own: one static Go binary in one container, driving kernel WireGuard over netlink, with a web console built in.

Free software, AGPL-3.0.

Чем Go полезен при разработке AI-агентов

Всем привет! Меня зовут Илья Данилкин , я тимлид в Авито Авто . AI-агенты обычно живут рядом с Python, но всё же немало команд выбирают язык Go. Дело в том, что агенты большую часть времени не заняты сложными математическими расчётами, а ждут ответа модели или результата инструмента. А ещё работают в режиме бесконечных параллельных запусков. И если пользователь останавливает задачу, его запрос и следующие вызовы инструментов тоже нужно остановить. Поэтому при выборе языка важны не только библиотеки для работы с моделями, но и то, как язык справляется с одновременными задачами, отменяет операции и насколько просто доставить готовое приложение пользователю. В Go для этого есть дешёвые горутины, context.Context и сборка в один бинарник. В статье на примерах и материалах из Go-сообщества разберу пять сценариев, когда эти и другие свойства Go очень и очень нужны.

We know the scurge of "AI" scraping bots. But it has become almost impossible to tell the difference between scraping bots and pentest bots. This is from a domain I purchased months ago and put something on late on the 26th. 3 humans including me know the domain and I guarantee the two others have not visited more than once (which was out of sheer politeness).

Look at this specific session, this is just a blitz probe, none of those URLs actually exist. The sheer volume is astounding. It's a Go application sitting behind a Caddy reverse proxy (both performing admirably) which reports the usage to Umami, which is what the screenshots are from.

Ускорение вычислений в алгоритме DRS-виртуализации через векторизацию

Разбираем net/http на практике: пишем веб-сервис DeadDrop для безопасного обмена сообщениями

Первая часть цикла «Разбираем net/http на практике»: создаём с нуля сервис DeadDrop — аналог Privnote для безопасной передачи самоуничтожающихся сообщений и файлов. На чистой стандартной библиотеке net/http разбираем основы: • запуск HTTP-сервера • маршрутизация в ServeMux • написание middleware (логирование и recovery от panic) • работа с HTML-шаблонами и layout’ами • подключение статики через http.FileServer и embed.FS В итоге получаем работающий сервер с красивой главной страницей, формой создания «ячейки» и базовой архитектурой проекта — всё без внешних зависимостей. Идеально для начинающих и тех, кто хочет глубоко понять внутренности популярных фреймворков вроде Gin и Echo. Пишем код вместе!

Monkey patching? В Go? Серьёзно? Или ка писать тесты и не сойти сума

На днях подходит ко мне коллега с вопросом: «Слушай, а как в Go сделать замену логики функции в тесте?» Я уточняю, что он имеет в виду. А он такой: «Ну, хочу monkey patching, чтобы подменять функции из коробки. Типа time.Now возвращала фиксированное время, uuid.New конкретный ID. Чтобы удобно тестироваться». И тут я, конечно, немного завис :D Да, технически в Go есть способы делать monkey patching (еще и есть библиотека ) через unsafe, через подмену указателей на функции в рантайме. Но это настолько хрупкое и непредсказуемое решение, что я бы не советовал тащить его в продакшен-код. Особенно когда есть нормальный, идиоматичный способ решить эту задачу.

bim assembly detection

The barely improved editor now adds better heuristics to detect what flavour of assembly language you're using and what architecture you're working on, so it can provide better highlighting appropriate for the platform you're writing code for. It's not perfect, but it now computes a score if it can't tell right away, and decides based on that combination of factors.

It mostly works for x86/64, Z80, and ARM. I probably should get around to adding 6502, 68000, MIPS, and a few others next. 🙂

Суслик и пингвин: кодим на Go под Linux

Язык ядра Linux, его модулей и утилит написаны на языке C. Хоть он и является старым языком и прародителем многих других, но его до сих пор используют. В экосистему линукса постепенно проникают и более молодые языки — например, Rust. Но сегодня мы поговорим об детище Google — GoLang. Я много пишу про этот замечательный язык и в этой статье предлагаю изучить основы системного программирования на Go, мы изучим как работать с ядром, юзерспейсом линукса. Расскажу об стандарте POSIX, а также узнаем, как сочетать C и Go-код.
