[Other] Show HN: Matrirc – run irssi in 2026, talk to people on Matrix This solves no real problem — Element works, there&#x27;s already a Matrix-to-IRC bridge running on half the FOSS networks, and probably nobody under 30 has opened irssi voluntarily this decade.<p>I wrote it anyway because I miss Esc 4 and clunky window-split commands.<p>Matrirc is a local IRC server that speaks Matrix on the back. Point irssi at localhost:6667, log in with Matrix creds, rooms show up as channels.<p>brew tap pawelb0&#x2F;tap brew install matrirc

[Other] Show HN: AI memory with biological decay (52% recall) Most RAG setups fail because they treat memory like a static filing cabinet. When every transient bug fix or abandoned rule is stored forever, the context window eventually chokes on noise, spiking token costs and degrading the agent&#x27;s reasoning.<p>This implementation experiments with a biological approach by using the Ebbinghaus forgetting curve to manage context as a living substrate. Memories are assigned a &quot;strength&quot; score where each recall reinforces the data and flattens its decay curve (spaced repetition), while unused data eventually hits a threshold and is pruned.<p>To solve the &quot;logical neighbor&quot; problem where semantic search misses relevant but non-similar nodes, a graph layer is layered over the vector store. Benchmarked against the LoCoMo dataset, this reached 52% Recall@5, nearly double the accuracy of stateless vector stores, while cutting token waste by roughly 84%.<p>Built as a local first MCP server using DuckDB, the hypothesis is that for agents handling long-running projects, &quot;what to forget&quot; is just as critical as &quot;what to remember.&quot; I&#x27;d be interested to hear if others are exploring non-linear decay or similar biological constraints for context management.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;sachitrafa&#x2F;cognitive-ai-memory" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;sachitrafa&#x2F;cognitive-ai-memory</a>

[Other] Show HN: WaveletLM – wavelet-based, attention-free model with O(n log n) scaling WaveletLM is a wavelet-based, attention-free architecture that replaces self-attention with learned lifting wavelet decomposition, a Fast Walsh-Hadamard Transform, per-scale gated spectral mixing with SwiGLU activation, an inverse FWHT, and wavelet reconstruction. Combined with expanded MLPs and sparse product-key memory, this yields a model with O(n log n) scaling in sequence length.<p>With 23.8 PPL on WikiText-103, WaveletLM beats both GPT-2 Medium, which was trained on 80× more data, and Transformer-XL Standard, which uses recurrence to extend its effective context. It is undertrained and underregularized due to budget constraints, so there is much room for development and improvement.<p>I invite anyone who is curious to examine the model, test it out, and extend its capabilities further. All code and weights are fully open source, and a PG-19 run will be completed in 2-3 days. Generations can be done in 4-5 GB VRAM at 28.8 tokens&#x2F;second, and the model is trainable in 16.25 hours with 20 GB of VRAM, both on a 5090.<p>README for comparison tables, instructions, logs, and future plans: <a href="https:&#x2F;&#x2F;github.com&#x2F;ramongougis&#x2F;WaveletLM" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ramongougis&#x2F;WaveletLM</a><p>Weights: <a href="https:&#x2F;&#x2F;huggingface.co&#x2F;ragou19&#x2F;WaveletLM&#x2F;tree&#x2F;main" rel="nofollow">https:&#x2F;&#x2F;huggingface.co&#x2F;ragou19&#x2F;WaveletLM&#x2F;tree&#x2F;main</a><p>Generations: <a href="https:&#x2F;&#x2F;github.com&#x2F;ramongougis&#x2F;WaveletLM&#x2F;blob&#x2F;main&#x2F;logs&#x2F;wikitext-103_2026-04-22_01-36-47&#x2F;generations.txt" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ramongougis&#x2F;WaveletLM&#x2F;blob&#x2F;main&#x2F;logs&#x2F;wiki...</a><p>The following samples were chosen for coherence, not factual accuracy. Factuality will require scaling and downstream techniques such as RAG and instruction tuning.<p>&gt; The history of the city is reflected in its architecture, which includes the historic Old Town and New Castle County Courthouse Square Historic District. The building was designed by John H. Stevens, who also designed the Albany-Fulton Celebration in 1906 and built a steel-hulled shipyard on the lake shore.<p>&gt; The album was released on August 25, 2007 by Sony Music Entertainment and features several songs from the record including &quot;Never Say Die&quot;, &quot;The Show&quot;, &quot;Don&#x27;t Cry for Me Argentina&quot; and a cover of &quot;I Can Only Imagine (But You Are Not Alone)&quot;.<p>&gt; The species was first described by Swedish zoologist Carl Linnaeus in 1758 as Agaricus adustus. The genus name is derived from the Latin words perma &quot;to tie&quot;, and pous (&quot;like&quot;) means &quot;with a large head&quot;. In 1821, French mycologists Jean-Baptiste de Lacaille placed it in section Cricetae of the order Carnivora. He later renamed it Spongiforma punctata after the Greek kribensis.

[Other] Show HN: Lambda ERP – Open-source ERP you can run through chat Hi HN, I built Lambda ERP, an open-source ERP prototype where chat is the primary interface.<p>It handles sales&#x2F;purchase flows, invoices, payments, inventory, double-entry accounting, reports, and chat-generated analytics. There’s a live demo in the README with 3 years of simulated data, plus a Docker Compose setup if you want to run it locally.<p>It is not production-ready yet; I’m looking for feedback on the architecture, the chat-first workflow, and whether this direction makes sense for small teams that can’t afford traditional ERP implementation projects.

[CLI Tool] Show HN: DSS, a lightweight TUI spreadsheet editor and dashboard in Go Hi there, I tried to build a CLI tool to edit and visualize Excel&#x2F;CSV files directly in the terminal, I called it &quot;dss&quot;.<p>I did it for fun to tweak spreadsheet formulas without leaving my terminal or opening heavy GUI apps.<p>It is an interactive editor of sheets with charts and formula engine diretly in TUI. The formula engine is handmaded but I&#x27;d like to improve it.<p>I copied a lot from my previous Datacmd project and from Termdash repo. Hoping to receive some feedback.
