I disagree that coding challenges are stupid, I actually find them having some of the best signal-to-noise ratio of any step in the interview. Maybe it depends a lot on what type of coding problem it is? One important aspect of doing the c

The only thing that comes to mind is the ESP32, but that isn't directly comparable. Something like the SAMD21 is about $1 at 5k quantities but only has one core and about 32-128k of RAM

$1 is a competitive price for a cortex m0+ processor, especially with single quantities! The QFN package is slightly painful for prototyping, but certainly isn't an issue for automated production. I will definitely add the RP4020 to m

My high school offered a post secondary program. A student could go to a local university (Kent State in Ohio in our case) and take many of the general education classes you needed anyways. I wish I took advantage, it would have saved me s

Do you think some sort of automated storefronts could replace the old hardware stores like RadioShack? I would love to have a place I could drive to and pick up some components that I need TODAY, and I always thought a giant vending machine

I am planning on not purchasing any new google smart home hardware. I am annoyed that my nest thermostat no longer has a way to interface with their API. I purchased it right before the Google acquisition and I would have gone with an Ecob

Curves can be a bit more complicated, plus generating the tool lift and moves! I also need to factor in scaling the drawing as well, plus speeds.

This is great! I just created a pen holding adapter for my 3d printer so I can do some plots. I still need to find a good way to efficiently convert SVG files to gcode, but this will be a good start. Inkscape has a gcode generation tool, b

Fundamentals are important for software engineering, just like they are important for any type of engineering! I certainly would be more comfortable driving across a bridge designed by engineers who understand material properties and so on.

I was curious and looked it up- Cisco is indeed still off of its peak stock price $52 vs $77 in 3/2000... But if you reinvested their dividends you would be a little closer! Just don't adjust for inflation! $10k invested on 1&#x2F

I think shielding doesn't necessarily mean lack of transparency, if they are a good manager they should be able to provide you context and information about the bigger picture while still protecting your time and representing your inte

I have always enjoyed coding most when it is part of a bigger project - such as writing firmware for an electronics project or writing a script to generate G-Code for a CNC machine. Connecting code to the real world is always the most fun.

My uncle used to come over and visit my family. He would play chess on our laptop (wasn't tech savvy but was amazing at chess) with a stack of sardines and a gallon of water. He'd then comment "haha your dog loves me! I wonde

For your retirement, yes diversify. Knowing and understanding technologies isn't the same thing as knowing and understanding tech stock. Just look at Peloton as an example - they did great during the pandemic, but just had a child di

I don't use strict UML, but I still find it useful to do work with block diagrams of systems to show relationships of major components. I used to use Yed, but now I like drawio.

With solar, available land isn't really a constraint so I don't think there is a huge need to put solar panels in the water versus just putting them on empty land or roofs.

Java is certainly more verbose, but I feel that nothing is free and being more concise comes with some costs. For some applications the trade off is certainly worth it! I use python and Django for personal projects to move quickly. But if

I am a Python (green) programmer who joined a team using Java (Brown), but I have found that working with Java has overall been a great experience. Most of that may be because of Intellij, but I find the verbosity helps prevent future bugs

I have a hard time believing that there aren't very specific regulations for threadmills that address hazards. When I worked on a consumer robotics project we had to follow IEC standards which defined exactly how far a hand could reac

The contractor who we were paying was known by other employees, so when someone else called into a status report sounding different they contacted my group (IT/Security). He was a devops engineer so we had to comb through all the acces

by roland35 6y ago
This is still an issue even if you're a contractor! The company should know who has access to their internal resources and codebase. If you are upfront about it, then of course it is fine. Make sure it's in the contract.

We had to fire someone doing this as well, he was caught because his "subcontractor" was calling into meetings and had a totally different accent! Please don't do this... Not only is it unethical, there are security, intellec

My house had a problem since the cable came in on one corner of my house, and my office was on the other side. Browsing was ok but things like video calls suffered, at least until I went with a Unifi BeaconHD.

I try to optimize my microwave button pushing too. I also have a +30 seconds button, so for 1:30 I can hit "1,3,0,Start" or "+30" three times and save a press!
