Meta seems to be making big bets on AI-powered hardware.
Aider is the best terminal AI coding tool I've used. But by default it sends every diff through your OpenAI or Anthropic key, which gets expensive fast on real refactors — a single 100-file repo map can torch a few dollars before Aider even reads your prompt. This post shows how to run Aider against any LLM provider — Ollama for free local runs, OpenRouter for mixed-provider routing, AWS Bedrock for the enterprise plate — through a single OpenAI-compatible endpoint. I'll use Lynkr , the self-hosted gateway I maintain, but the pattern works with any OpenAI-compatible proxy. Full disclosure: I build Lynkr. I'll point out where it loses to LiteLLM and OpenRouter further down so you can make an honest call. The setup in three commands # 1. Start the gateway npx lynkr@latest # 2. Point Aider at it export OPENAI_API_BASE = http://localhost:8081/v1 export OPENAI_API_KEY = any-value # 3. Run Aider with any model name Lynkr knows about aider --model openai/gpt-4o That's it. Aider speaks the OpenAI Chat Completions protocol; Lynkr speaks it back and quietly translates the call to whichever upstream provider you've configured (Ollama, Bedrock, Anthropic, Azure, OpenRouter, Databricks, llama.cpp, LM Studio, ...). Aider has no idea it's talking to a router. Why bother? The cost math Aider's own leaderboard shows GPT-4o and Claude 3.5 Sonnet at the top — but you don't need a $3-per-million-tokens model to rename a variable. You need it for the architecture decisions. Lynkr's tier routing splits the work: Aider call type Routes to Cost Repo map summarization qwen2.5-coder:7b (Ollama, local) $0 File edits, single-function diffs gemini-flash-1.5 (OpenRouter) ~$0.075/M Architecture / multi-file refactors claude-3.5-sonnet (Anthropic) $3/M On a typical 4-hour Aider session, 80–90% of the calls are repo-map and small-diff calls. Routing those to local + cheap models while keeping Claude Sonnet for the hard reasoning has cut my own Aider spend by roughly 70%. Your mileage will vary base
Criei um gerenciador de downloads desktop em Python e quero feedback da comunidade! O PyFlowDownloader é um app desktop feito com Python + PySide6 que usa yt-dlp para baixar vídeos e áudios de forma assíncrona do youtube. Algumas coisas que ele já faz: Fila de downloads com progresso em tempo real Cancelamento de downloads ativos ou pendentes Suporte a MP4 e MP3, de 144p até 1080p Histórico com exportação para CSV Interface desktop com tema visual via QSS Build para Windows via PyInstaller + pipeline de release no GitHub Actions Está na versão v0.3.0 e ainda tem muito espaço pra crescer. Repositório: https://github.com/Vinny00101/PyFlowDownloader Se você puder **testar e deixar sua opinião nos comentários, ficaria muito grato! Quer saber: O que achou da experiência de uso? Algum bug que encontrou? O que você adicionaria ou melhoraria no projeto? Todo feedback é bem-vindo!
Happy to announce HeliosProxy !! Far beyond a pooling tool, HeliosProxy ** is a next-gen programmable Postgres data-plane. **Works with PostgreSQL-compatible databases , not only HeliosDB. It starts as a PgBouncer-compatible wedge, then adds the operational surface teams usually build from multiple tools: connection pooling failover and transaction replay shadow execution anomaly detection edge cache controls admin REST API embedded admin UI signed WASM plugins OCI-style plugin artifacts Kubernetes operator Terraform and Pulumi providers 22 installable Claude/Codex operator skills Install operator skills: heliosdb-proxy install skills PostgreSQL #DevOps #SRE #Database #AIcoding
This was my very first side project 3 years ago. I guess I have a soft spot for it, because this is actually my 3rd time completely rewriting it from scratch. The new version turns flat scanned PDFs into searchable files, or converts photos of text into editable Word docs. It runs client-side for privacy (except for ai features), and the core OCR features are completely unlimited (no account required). → https://olocr.com submitted by /u/Embarrassed_Ad719 [link] [留言]
Event sourcing gets sold on immutability. You don't update, you don't delete, you only append, so the history is permanent. It mostly isn't. The events are immutable because your code agrees not to touch them, not because anything actually stops it. Underneath they're still rows in Postgres, and rows have a DBA with write access. A migration that "cleans up" old data. A 2 a.m. query run against the wrong connection. A backup restored with slightly different bytes in it. Change one of those rows and a replay won't blink. The aggregate rebuilds, the projections rebuild, everything looks fine. Usually the first person to notice is a customer whose balance is off, and by then the trail is cold. Chain each event into the next The trick is small. Give every row two extra columns: a hash of its contents, and the hash of the row before it. #1 AccountOpened prev=00000… hash=70be4f… │ ▼ #2 AmountDeposited prev=70be4f… hash=796018… │ ▼ #3 AmountWithdrawn prev=796018… hash=6a0260… The hash is SHA-256(previousHash || json(payload)) . Nothing exotic. The point is that each hash depends on the one before it. Edit a payload and its hash stops matching. Rewrite that hash to cover for the edit, and now the next row's pointer is wrong. You can't fix one without breaking the next. About forty lines of it Appending an event hashes it together with the previous one: public HashChainedEntry Append ( object payload ) { var previousHash = _entries . Count == 0 ? GenesisHash : _entries [^ 1 ]. Hash ; var hash = ComputeHash ( previousHash , payload ); var entry = new HashChainedEntry ( _entries . Count + 1 , payload , previousHash , hash ); _entries . Add ( entry ); return entry ; } internal static byte [] ComputeHash ( byte [] previousHash , object payload ) { var payloadJson = JsonSerializer . SerializeToUtf8Bytes ( payload , payload . GetType ()); var combined = new byte [ previousHash . Length + payloadJson . Length ]; Buffer . BlockCopy ( previousHash , 0 , combined , 0 , previousHash .
