Interviewing Engineers

Note: This is an opinionated guide. While it is most effective for on-site, the same pattern can work with remote candidates.

How To Interview Engineers

Interviewing is hard. It's not easy to find good people, and once you do, it's often difficult to find out what they can do and how they work. A badly-run interview can pass over a great engineer. Conversely, some engineers are good at passing traditional tech interviews, but bring major problems with work habits or team fit.

The first priority of any manager is to hire the best people. Everything else must wait.

Klipper Pressure Advance Line Calibration Macro
[gcode_macro PA_CAL]
# Klipper pressure advance line calibration macro.
# Usage: PA_CAL BED=100 NOZZLE=240 PA_START=0.0 PA_STOP=0.1 NZL=0.4
# Or you can execute with no parameters, which will use values from printer.cfg and saved_variables.cfg.
# First prints a line with current set PA, then prints 21 additional line segments starting with PA_START, and increasing to PA_STOP.
# Based on http://realdeuce.github.io/Voron/PA/pressure_advance.html
# Cleaned up and moved to using saved_variables.cfg by u/jibbsisme
# Sourced from u/Deepsiks, assisted by u/imoftendisgruntled, u/scul86, and thanks to u/beansisfat, u/stray_r

A simple installation guide for i3-gaps

Installing i3-gaps

Dependencies

i3-gaps has some packages that are required for it to work so install these things:

sudo apt install libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf xutils-dev libtool automake

You also need to install libxcb-xrm-dev, but I got Unable to locate package libxcb-xrm-dev when trying to install from the apt repositories on Ubuntu 16.04. If this happens to you, just install it from source using these commands:

mkdir tmp

# Install ARCH Linux with encrypted file-system and UEFI
# The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description.
# Download the archiso image from https://www.archlinux.org/
# Copy to a usb-drive
dd if=archlinux.img of=/dev/sdX bs=16M && sync # on linux
# Boot from the usb. If the usb fails to boot, make sure that secure boot is disabled in the BIOS configuration.

Frequency Tester

Frequency Testing

This will allow you to test a specific frequency that you hear when you do your resonance testing in Klipper and potentially track down where extra peaks are coming from. If something is rattling at a specific frequency, you can specify that frequency and feel around the printer until you track it down.

Code was adopted by zifnab from somewhere in Klipper.

Usage

You have to have [resonance_holder] in your printer.cfg.

The command is HOLD_RESONANCE AXIS=<axis> FREQ=int SECONDS=<seconds>
