I got made aware that this setup is now deprecated. You can simply follow these instructions here: https://community.torproject.org/de/relay/setup/snowflake/standalone/debian/. (Debian 12 - bookworm is required!)
This is a guide for installing Tor Snowflake on your Raspberry Pi as systemd service.

Asked to implement a stack in Go. Here's a generic, thread-safe, interface-driven implementation with proper error handling. package main import ( "errors" "fmt" "sync" ) // ErrStackEmpty is returned when attempting to pop or peek an empty stack. var ErrStackEmpty = errors.New("stack: operation on empty stack") // Stacker defines the contract for any stack-like data...
A developer wants to generate ASCII art representations of their GitHub contribution graph, but only for commits that match a specific emotional tone. The task requires fetching contribution data, analyzing commit messages for sentiment, and rendering the results as customizable block characters. package main import ( "fmt" "strings" "time" ) // ContributionIntensity represents the emotional...
O duo britânico The Chemical Brothers lançou a playlist oficial “Go: Apex And Beyond”, uma seleção de músicas criada para apresentar diferentes fases da trajetória da dupla a novos ouvintes. A iniciativa foi anunciada após o aumento da popularidade de “Go”, faixa originalmente lançada em 2015. Segundo informações divulgadas pelo grupo, a música registrou crescimento […]
Build a task scheduler that processes jobs with exponential backoff retry logic, but also tracks what the execution state would have been if tasks had been run in reverse chronological order. This serves no practical purpose, but seemed like a good idea at 2 AM. package main import ( "context" "fmt" "math" "sync" "time" )...
In 2018 I recreated this blog with an SSG (Static Site Generator) in Python based on pandoc (asciidoctor for older pages), git timestamps and Jinja2 templates. Even though it cached pandoc invocations, building still took too long for my taste and lately I didn’t really feel at ease with modifying…
A developer wants to build a tool that analyzes Go source code and flags comments that contradict what the code actually does. The tool should parse functions, extract their comments, and use a scoring system to determine if the documented behavior matches reality. package main import ( "fmt" "go/ast" "go/parser" "go/token" "regexp" "strings" ) //...
How cmd/go's script tests led me to testscript, and how to use it for CLI tests that exercise argv, stdout, stderr, exit codes, and scratch files.

txtar is a tiny plain-text archive format Russ Cox introduced in 2018 for multi-file test fixtures. The Go Playground, cmd/go's script tests, gopls's marker tests, and rsc.io/rf all reach for it.

The default slog API is loose enough that a careless line ships broken JSON to production. Pin it down with Attr constructors, LogAttrs, a context-borne logger, and sloglint.

Rust is a systems programming language focused on memory safety without a garbage collector, achieved through a compile-time ownership model. It produces native binaries with C-like performance and zero-cost abstractions, while preventing entire classes of bugs (use-after-free, data races) at the type level.

Four of the five steps in every unary RPC handler are wire plumbing. Pin the service function signature and they fit in one generic adapter per transport.

A Go closure holds a live reference to whatever it captures, not a snapshot. Real examples of where this trips people up, and how to keep it boring.

A quick tour of Go struct tags: how different libraries use them, how you read them at runtime with reflection, and how other tools read them at build time instead.

Translating errors at layer boundaries so storage details don't leak into the handler or, worse, into client responses.

When you’re programming microcontrollers, you’re likely to think in C if you’re old-school, Rust if you’re trendy, or Python if you want it done quick and have resources to spare. …read more
Why logging at every layer of a service produces noise, and how to log only at the handler level while propagating context from below.

About five months ago I wrote about Absurd, a durable execution system we built for our own use at Earendil, sitting entirely on top of Postgres and Postgres alone. The pitch was simple: you don’t need a separate service, a compiler plugin, or an entire runtime to get durable workflows. You need a SQL file and a thin SDK.
Since then we’ve been running it in production, and I figured it’s worth…
