I’m Alejandro, a senior electronics engineer building AI systems for the real world. I’m not interested in AI as content or demo-only workflows. What interests me is this: taking real operational knowledge from people who live the work every day and turning it into useful systems. That’s the kind of work I’m doing now: • practical AI tools for real business workflows • agent-based systems shaped by domain expertise • software for engineering, operations, and automation • projects like NormaLang and CoordinIA I’ll use this account to share: • what I’m building • what actually works with AI agents • mistakes, tradeoffs, and edge cases • lessons from turning real-world knowledge into practical tools If you care about practical AI, real workflows, and building things that survive contact with reality, you’ll probably like this account.

@ronnyMH123 @Watchdog_MP “Pay taxes for five years but don’t use the services.” Amazing policy thinking. No private healthcare alternative, no realistic plan, just resentment and zero understanding of how the system actually works.

@alejandro_spi @Watchdog_MP Every newcomer should have to put in for five years minimum before receiving free healthcare and or any perks such as child tax, GST, etc. Should never be allowed welfare or subsidy housing. Education for kids is fine.

🚨 $1.1 BILLION in Canada Child Benefit payments went to temporary residents in 2025 alone. That’s international students & temp foreign workers. Nearly $3 BILLION over 5 years and it’s TRIPLED recently. While Canadian families struggle with housing & costs, taxpayers are funding kids of non-permanent residents? When does this end? 🇨🇦 #TaxpayersFirst #CCB

@thegrimwulff @WSB_redditor @Watchdog_MP You wrote a whole bloodline speech and still don’t know the law of your own country. Having a child in Canada doesn’t give the parents citizenship, PR, or any automatic right to stay. That “anchor baby” comment only exposed your ignorance.

@m_ebrard Qué gusto ver que @diego_ruzzarin seguramente hizo esta colaboración gratis, porque cobrar por promover eventos sería demasiado capitalista.

@DavidOndrej1 8 hours ago you were preaching DeepSeek. Now $200/mo ChatGPT is suddenly “insane value.” That pivot was faster than the model response time.

the $200/mo ChatGPT subscription is insane the amount of value you get is unheard of easily $2,000+ worth of tokens right there if you don't see this, you're ngmi

@thegrimwulff @Watchdog_MP Funny how my taxes belong here, but apparently I don’t. I’m here legally, I work, pay taxes, and support my family. If your issue is with government policy, argue policy. Telling people to go back to “their own country” is just xenophobia dressed up as concern for taxpayers.

Claude Opus 4.7 is doing an excellent job. The capability is clearly there. My concern is token usage: it’s extremely high. On a single serious task, it can burn through the usage limit very quickly. That creates an unusual bottleneck: development becomes slower not because the model is less capable, but because the cost of using it at full depth is hard to sustain. In practice, the limiting factor stops being intelligence and starts being token efficiency.

Brutally true. And let's call it out: every YouTuber claiming they're "building an empire" on a Mac Studio or an NVIDIA DGX Spark with local models is lying. The only thing they're building is their YouTube channel and their X following. Nothing real, nothing that ships. @AlexFinn
BridgeMind@bridgemindai

Spent the last few days vibe coding on my NVIDIA DGX Spark. Here's what I learned. Qwen 3.5 122B took one minute and nine seconds to respond "Hi how are you doing". Unusable for vibe coding. Gemma 4 was fast but built a dot instead of a first person shooter game. GPT-OSS 120B was the sweet spot. Fast, capable, and actually produced working HTML. Open source models running locally are not replacing Claude Opus 4.6 or Codex with GPT 5.4. Not even close. But they're getting better every month. The new DGX Spark Bench is live on bridgebench.ai. Real-world benchmarks for local models on local hardware. This is just the start. Full video below.

@melvynx I've been running Hermes with ChatGPT across three projects and still haven't hit the weekly cap. So far, so good.

@0x_Discover Lost my job, rent due, no backup plan — but still paying $20/month for Claude. Now that's brand loyalty.

I lost my job yesterday Rent was due No backup plan Then I remembered I still had Claude Asked it: “Analyze every top Polymarket wallet from the last 90 days and build me something” $25 → $4,237 in one night It ingested 10,000 wallets Cross-referenced win rates, sizing patterns Market selection identified 7 traders whose edge wasn’t luck Then it built an autonomous AI agent Not a script — not an if-then bot An agent that reads live news feeds Maps them to open markets Runs probabilistic inference on crowd mispricing Detects cross-market arbitrage between correlated outcomes Sizes positions using Kelly Criterion derived from the wallet patterns it studied I deployed it at 11:47PM Closed the laptop Woke up to a notification $25 → $4,237 94 trades while I slept Never asked me anything Never paused Never second-guessed That’s the entire game Information asymmetry at machine speed Wall Street pays $2M/year for this I paid $20/month for Claude Copy it here:t.me/KreoPolyBot?st…

@adiix_official $1.18 to $3.3M. Comment 'GUIDE' to receive. The Chinese engineers must be thrilled their millions are being distributed via Twitter likes.

Usé OpenClaw por 3 meses. Por curiosidad probé Hermes Agent y no pienso regresar. Aquí dejo la guía que me hubiera gustado tener para la instalación y configuración de Hermes desde cero. @NousResearch @teknium @karan4d
