I've been thinking of reverting back to Circle CI.

Does zizmor catch this pull_request_target vs cache poison vulnerability?

Rewrite following a new architecture plan could get finished pretty quickly, treating the original as a prototype.

They use a bespoke language to define LLM-generated UI components. I think that this is supposed to prevent exfiltration if the LLM is prompt-injected. In any case, the parser compiles chunks streaming from the LLM to build a live UI. The WASM parser restarted from the beginning upon each chunk received. Fixing this algorithm to work more incrementally (while porting from Rust to TypeScript) improved performance a lot.

We're looking for a senior backend engineer to evolve our core platform — time-series data systems, AI-assisted analytics, cloud infrastructure, and data ingestion pipelines. You'll take ownership of complex systems, drive major technical migrations, and shape how intelligence is embedded into industrial energy workflows. Think: AI evals and prompt engineering, MQTT ingestion pipelines, time-series schema design, PostgreSQL infrastructure, and ML platform support.

Stack: Python, TypeScript, Supabase, PostgreSQL, MQTT, TigerData, InfluxDB, AWS. 5+ years experience building production backend systems. FinTech, quantitative analysis, or econometrics background is a strong plus.

$125K–$150K + meaningful equity. Reach out to me at jnapoli+hn@cvector.com

WebMCP should be a really easy way to add some handy automation functionality to your website. This is probably most useful for internal applications.

This looks nice! I like the idea of providing more deterministic feedback and more or less forcing the assistant to follow a particular development process. Do you have evidence that gtg improves the overall workflow? I think that there is a trade-off between risk of getting stuck (iteration without reaching gtg-green) versus reaching perfect 100% completion.

Merry Christmas from Rhode Island!

Yeah, maybe it would be nice to have a fast-track onboarding option for common goals: lose weight, finish homework or chores, etc.

I don’t think that “Claude Code” is relevant to this semantic grep tool.

Yes, this is it. When I'm experimenting, I'm happy to pay an extra $40 for the name-brand device that has 1000s of blog posts supporting it, since it's probably this community is going to help me be more successful and learn faster.

I would reconsider the choice when I have a commercial product that I have some scale of production, where a few bucks off the BOM is important.

There is now a lot more uncertainty and delay for legal immigrants when crossing into the USA.

For the time being, AI doesn’t have good access to a lot of things: customers, information in 3rd party systems, etc. Even when we give access (with MCP, for example), current AI has trouble locating the right information to solve a problem.

So I still need an engineer to find out why the distributed system isn’t performing correctly, or to create a new component that is coherent with the rest of the existing UI. The difference is that any particular engineer will find more success tackling a wider range of goals.

I think that AI will let us make better progress outside of our narrow expertise.

So entrepreneurial activities will be easier and more common. On the other hand, there will be relatively fewer opportunities for specialized consultants. Contractors and consultants should be able to solve bigger problems rather than working in narrow specialties.

Teams and companies should have fewer members, since fewer specialties are needed. So they will probably need more contractors to move things along when there is a lot of work to do.

Normally, Autopilot does not require your foot on the accelerator. Pressing the accelerator overrides it to make to car move ahead where the autopilot decided to stop. At the time, autopilot would always stop at an intersection, and the driver was supposed to move ahead when it is clear.

Just put in the prompt customization to model responses on Marvin from Hitchhiker's Guide.

"Here I am, brain the size of a planet, and they ask me to ..."

Yep, you are also right.

There is obviously some distribution of productivity in software developers. In young startups, a highly productive developer has an outsized impact. A delay in product development can mean the company is entirely blocked from advancing its growth. The cost of a “slow” developer can become the entire burn rate of the company, as everyone waits for X to be finished. A more productive developer has a better chance of staying ahead of the critical path.

US universities are being punished for allowing free speech of individual members. The federal government is angling to get these groups to self-censor.

On the hiring side, Motion Recruitment had good communication and good results for me. The agent tremendously improves the signal/noise ratio in the beginning of the hiring funnel.

I'm not sure that's really the case. Most states have a pretty good mix of Democrats and Republicans.

Yeah; start-ups will start paying tax much sooner since salaries are the main expense in software development, and only a fraction can be deducted per year. The tax change must make things marginally more difficult for young companies that have some revenue, aren't cash-flow positive, and have a short horizon.

I think that this is the answer. Maybe someone who is great with Postgres Row Level Security will have an OK time with Supabase security, even if they are vibe coding. They wouldn't think of asking the AI for something that won't work.
