d0100··on Training a 4B model to produce 81% faster query plans than Postgres
I've reduced queries from minutes long to 2s in Postgres by duplicating a CTE and keeping it unused

Query planner feels pretty LLM-esque already

d0100··on Fable 5.1 Solves the Cyphral Distich, a 370-year-old cipher
LLMs seem to create abstract, local jargon as a side effect of way it reasons using tokens

ChatGPT told me its "semantic compression"

d0100··on LG TVs caught spying even when offline or on standby
Gamers Nexus has a 2h video doing reverse engineering and a lot of tests
d0100··on DaVinci Resolve 21.1
We can always streamline creativity by allowing agents to post jobs on mechanical Turk
d0100··on AWS Acquires DuckDB
> a self-contained, signed extension ecosystem

What does this mean? Can I easily sign my own private extensions with my own key?

We are currently allowing unsigned extensions, loading them, then locking the duckdb config to prevent loading unsigned/untrusted extensions

d0100··on Not hiring junior engineers won't solve the problem you think you have
> we hire Juniors to help fill the talent pool with the hope that they will be productive in a few months

The sad reality for smaller companies is that we cannot compete salary-wise, which means training juniors that will leave the minute they become productive

But mostly the issue is with the market, there are only so many things you need a junior to do in a body shop that is getting squeezed

Other companies are also cash constrained and need to pivot fast to "AI"-something, which juniors wont really help with on the short-term

d0100··on Microsoft has released software updates to plug at least 570 security holes
An employee just got phished by adding a number to a legitimate deviceAdd login route that bypasses 2FA and adds a device with full access to office and mail

Probably working as intended...

d0100··on Ask HN: What is your (AI) dev tech stack / workflow?
My workflow for production code:

1. Pick the most complete project boilerplate (fullstack JS can easily introduce security bugs, SPA + API is best as cheap linting solves most problems)

2. Project skills (how to CRUD without mess)

3. Use worktrees for concurrent features, local session for conflicts

4. Local session for QA and refinement

I use Copilot and GPT 5.4

Managed to shorten pre-AI priced ongoing projects to 2 weeks or a month

d0100··on AI is too expensive
> GPT 5.4 instead of 5.5.

I am exclusively using 5.4 because its only 1x and very good, but the github calculation showed my once $40 become a $680 billing

That is too expensive and not worth paying

d0100··on If AI writes your code, why use Python?
> Python is, thus, clearly superior to other languages in terms of ease of review.

Do we get visual comparisons along with this bold claim?

d0100··on Show HN: I built an open-source email builder, alternative to Beefree/Unlayer
I remember doing a MailChimp "clone" in Laravel some 12 years ago and implementing an email builder using their templates
d0100··on Flue is a TypeScript framework for building the next generation of agents
I am using TS sandboxed in deno for all our agent code generated from a UI builder (inspired by OpenAI's own agent builder, and spits out the same code output)
d0100··on Does Postgres Scale?
Are you using Temporal with distributed workers?

We have a simple worker setup and temporal is pretty easy to setup

Out only issue is really needing an intermediary data store for task result storage

We are using DBOS in new projects as it's even simpler and the downside (task log interface behind saas) is easily remedied with a copilot generated task viewer

d0100··on Zed 1.0
Tried using Zed but for some reason the AI can't open the browser?
d0100··on Who owns the code Claude Code wrote?
The trick is to constrain the LLM to program in a very defined coding style

If I make the LLM generate code that follows my own code architecture and style, that should be enough creative input

d0100··on Measuring Claude 4.7's tokenizer costs
I went from plan with opus, implement with claude, to simply plan and implement with GPT 5.4

It's a very good model for a very good price

d0100··on Claude.ai down
GPT 5.4 is working pretty well for me, both in Copilot and Codex vscode extensions

If you create a plan it follows it closely

d0100··on Instant 1.0, a backend for AI-coded apps
Any example more complex in the backend?

Are we supposed to expose all entities and relationships and rely on row level security?

d0100··on Code Is Cheap Now, and That Changes Everything
AI assisted development is the generalists dream

Althought it still hasn't solved procrastinating the next plan prompt

d0100··on 'The Secret Agent': Exploring a Vibrant, yet Violent Brazil (2025)
> In a certain way, that's how Brazilian culture works

That's how Brazilian media conglomerate culture works

d0100··on Edge.js: Run Node apps inside a WebAssembly sandbox
I still prefer Deno because I don't need a separate npm install command, which makes running code that much easier

Being able to import from "https://my-vpn.com/mypackage@1.2.3" or "npm:package@1.2.3" and just running code without having to worry about scaffolding node_modules makes sandboxing code much easier

d0100··on Bus travel from Lima to Rio de Janeiro
In pt-br it's "leito", "semi-leito", "executivo" and "convencional"

"Leito" sounds more premium than "cama", despite being both valid words for "bed"

d0100··on Can I run AI locally?
Why is there no RTX 5060ti?
d0100··on Show HN: How I Topped the HuggingFace Open LLM Leaderboard on Two Gaming GPUs
I wonder if joining layers from the "organs" of different models could further enhance the results
d0100··on Better JIT for Postgres
I've shaved off 30s of queries by transforming json columns into a string after the first CTE is done with it
d0100··on Layoffs at Block
If you apply Pareto to productivity, you can fire a lot of people and still manage
d0100··on The Sideprocalypse
I haven't had much success using LLM's in Unity as there is a lot of work that goes into the editor and cannot be done via code, especially if you are using several different assets
d0100··on Gradient.horse
How many crabs where drawn?
d0100··on Show HN: First Claude Code client for Ollama local models
Does this UI work with Open Code?
d0100··on The challenges of soft delete
In simple projects where database is only changed via an API, we just audit the API instead. It's easier to display and easier to store than tracking each DB change a single transaction does
