Building and deploying a Voice AI Agent to portfolio in 30 minutes
https://www.reddit.com/r/programming/comments/1m0b4b2/building_and_deploying_a_voice_ai_agent_to/
<!-- SC_OFF -->I have been experimenting with AI agents for a while now but I was looking to create a Voice AI Agent. It felt a little intimidating (since I was new to this space). So I took the chance to learn the core components with principles and understand how everything fits together. They are basically autonomous system that listens to your voice, understand what you are saying (using speech-to-text), respond using Large Language Models (LLMs) like GPT-4 and speak the answer back to you using a synthetic voice (text-to-speech). I found some amazing platforms like Rime, Vapi, Retell AI, VoiceHub, ElevenLabs so I tried a couple of them and created a post to cover everything I picked up: → building blocks
→ popular frameworks (Retell AI, LiveKit..)
→ step-by-step guide to build, test & deploy
→ real use cases I decided to go with VoiceHub as it supports flexible provider options (and free credits): - Speech-to-Text: Google, Deepgram, Gladia, Azure
- Text-to-Speech: ElevenLabs, Deepgram, Azure, OpenAI
- LLM: OpenAI, Claude, DeepSeek, Ollama, Grok Under the hood, I used ElevenLabs voices & OpenAI GPT-4o as model. read it here (free on medium): here (https://levelup.gitconnected.com/i-built-and-deployed-a-voice-ai-agent-to-my-portfolio-in-30-minutes-dd28dbbf0aed?sk=3a69bccd92dcdb5d7df2bc0914c48149) Have you built any voice ai agents before? curious to know what you think. p.s. currently trying 11.ai (alpha) by ElevenLabs. <!-- SC_ON --> submitted by /u/anmolbaranwal (https://www.reddit.com/user/anmolbaranwal)

How I Doubled My Lookup Performance with a Bitwise Trick
https://www.reddit.com/r/programming/comments/1m0tcd6/how_i_doubled_my_lookup_performance_with_a/
<!-- SC_OFF -->Hey folks, While working on a Cuckoo Filter implementation, I originally used a simple byte array to store 4-slot buckets, each holding 1-byte fingerprints. Then it hit me—those 4 bytes fit perfectly into a 32-bit integer. So why not treat the whole bucket as a single uint? That small insight led to a few evenings of playing with bitwise operations. Eventually, I replaced loops and branching with a compact SWAR (https://en.wikipedia.org/wiki/SWAR). Here's what it is in one line: ((bucket ^ (fp * 0x01010101U)) - 0x01010101U) & ~(bucket ^ (fp * 0x01010101U)) & 0x80808080U) != 0 Over 60% faster positive lookups and more than 2× faster negative lookups. I liked the result enough to write up the whole journey in an article: the idea, the math, step-by-step explanation, and the benchmarks. If that one-liner looks scary, don't worry—it's not as bad as it seems. And it was fun stuff to explore. <!-- SC_ON --> submitted by /u/axel-user (https://www.reddit.com/user/axel-user)

ANSI Escape Codes
https://www.reddit.com/r/programming/comments/1m0byvn/ansi_escape_codes/
<!-- SC_OFF -->Working with and debugging ANSI control codes and escape sequences can be a challenge. This free web-based tool helps to inspect the input, visualize colors and styling, and list control codes. By using a proper tokenizer and parser (not just regex hacks), it supports all sorts of control codes. The parser is open source and available too (find links in "about"). Type or paste text in the black text area, or try out the examples. Use the lookup table to filter & find specific codes. Feedback welcome, I’d love to know what’s confusing, missing, or especially useful. <!-- SC_ON --> submitted by /u/webprolific (https://www.reddit.com/user/webprolific)
