Why Use Data Build Tools (dbt) - Lemmy.World

Time and again I see the same questions asked: “Why should I use dbt?” or “I don’t understand what value dbt offers”. So I thought I’d put together an article that touches on some of the benefits, as well as putting together a step through on setting up a new project (using DuckDB as the database), complete with associated GitHub repo for you to take a look at. Having used dbt since early 2018, and with my partner being a dbt trainer, I hope that this article is useful for some of you. The link is paywall bypassed.

Offline listening and speaking bot - Lemmy.World

Hi all, For those wanting a quick repo to use as a basis to get started, I’ve created jen-ai. There are full instructions in the readme. Once running you can talk to it, and it will respond. It’s basic, but a place to start.

The pain of realising you got your PCB wrong, and need to use two pins earmarked for the LCD for the TX & RX to allow the sides to communicate :-( - Lemmy.World

Hoping for guidance on custom split QMK using Blackpill - Lemmy.World

Hi all, I’m hoping for some troubleshooting tips. I have a self-build split keyboard using Blackpills. If I flash either side with ‘SPLIT_KEYBOARD = no’ in my rules.mk [http://rules.mk], then both sides work fine (but both working as the left side). If however I set ‘SPLIT_KEYBOARD = yes’, then both sides stop working. It’s driving me insane! These are the relevant details of rules.mk [http://rules.mk]: MCU = STM32F401 BOOTLOADER = stm32-dfu SPLIT_KEYBOARD = yes SERIAL_DRIVER = usart And config.h: #pragma once #define HAL_USE_SERIAL TRUE #define SOFT_SERIAL_PIN A12 #define MASTER_LEFT #define MATRIX_ROWS 6 #define MATRIX_COLS 6 #define SERIAL_USART_DRIVER SD1 #define SERIAL_USART_TX_PAL_MODE 7 And halconf.h: #pragma once #define SERIAL_USB_BUFFERS_SIZE 256 #include_next And mcuconf.h: #pragma once #include_next #undef STM32_SERIAL_USE_USART1 #define STM32_SERIAL_USE_USART1 TRUE Please help! I’ve been at this for three days.

OpenSCAD Question on bezel - Lemmy.world

I created a 2d surface that I can perform a linear extrusion on, however the result it obviously a hard edge on the extrusion. I would love to be able to add a bezel - either rounded or at 45 degrees. Is there an easy way?

Any OpenSCAD whiz available to provide some advice? - Lemmy.world

I’ve got the basics down, but now looking to do something more complex, and unsure if it’s possible. I have imported a flat shape (a pcb), and I can extrude this out. What I want to do however is to rotate it on its axis, and then extrude it down the z-axis (not directly out from the surface). Is this possible, and if so, how?

Online tool to test a pcb design - Lemmy.world

Is there such a thing as an online pcb tester? As in ‘here is my pcb design, when I connect this, I expect it to register as a circuit on these two pins’
