The AI Trade Meets the Ballot Box: a $2.3 Trillion Thursday and a Cautious Friday
On November 5 the Nasdaq 100 fell more than 6% and chip stocks 12% as markets repriced the AI buildout after the midterms. Friday's bounce was partial; the open question is now electricity, not models.

GPT-6 Cyber: A 'Critical' Model, a Guest List, and a Longer Patch Queue
OpenAI released GPT-6 Cyber on November 5 to vetted Daybreak Red customers, rating it Critical under its own framework. The vendor numbers are striking; the real bill lands on everyone's patch queue.

How Deslopping works: one AI-written pull request, from risk score to merge
A step-by-step walk through Deslopping: how a pull request is scored, how its questions are written and tested, what happens after a wrong answer, and what a team learns about its AI without ever seeing a person.

I built an app that puts engineers back behind the wheel of AI-written code
AI writes more of our code every month, and the approve button has quietly become a rubber stamp. Why I built Deslopping, a GitHub check that asks engineers to show they understand a change, and never ranks them.

Sheet 3 of 4 · On the bench
Things I build for myself.
Small products shipped under my own name. Each one is a test rig for the shop and a source of notes.
Mk I · Mobile
Low Bar
A habit tracker that sets the bar low on purpose. Show up, mark the day, keep the streak honest.
Pre-launch
Mk I · Dev tools
Deslopping
Proof that an engineer read the AI-written code before approving the pull request. Comprehension, not vibes.
In progress
Mk I · SaaS
Bookleys
Booking and client memory for service professionals. The calendar that remembers who people are.

DevLazar.
One engineer, three stations.
Lazar Stanković PR DevLazar · Clients abroad
The company behind the work. Custom software, MVPs on a deadline, and backend systems that have to hold when the traffic arrives. Everything leaves the shop with drawings.
Station 01
Proof of concept, MVP, product
Built fast with AI to a working POC in days, then the MVP in weeks, then the full product. Each stage scoped to survive the launch.
Station 02
Backend architecture and scale
Pipelines, auth, APIs under high-frequency load. Monthly retainer.
Station 03
Launch Survival Audit
A fixed-price inspection before your system meets its users.

An engineer who writes things down.
I have built for banks, hospitals, insurers and sensor networks. Most of it I cannot show you. All of it taught me something, and the lessons are not under NDA.

The Wire.
One letter a week on AI infrastructure, shipping on a deadline, and the craft of building things that last. No noise, no sponsors you did not ask for.
