Agility is both ability to move fast but also the ability change direction and manoeuvre with haste. In order to do that information is needed, and that information needs to be acted on = feedback loops. @allankellynet

Agreed. In that situation. Not easy. But also a sign for leadership, bring me something to push, to be positive about!.
CTOs and Engineering Managers are in a tough spot right now. Just a couple years ago, you'd hire 5-10 people per quarter. Convince your best engineers to stay, despite competing offers. And negotiate salary budget increases with your CEO. Now it's a different market:.

Just published an article about #git workflows and best practices. Strangely, I’ve been sitting on this for four years. Maybe too scared to publish? . #developer #workflow #BestPractice #SoftwareEngineering.

This is what I look for when hiring. Technical skills can be learned.
Someone excited to learn. Engineers with a growth mindset are some of the brightest out there.

3D is hard. Why has nobody created Figma for 3D? (Free idea! I'm busy building this. ) #raspberrypi

One of my first jobs ever was optimizing an export script making hundreds of sql queries for each combination of arguments, it took 3-6hrs to run, I loaded the entire table into memory and had it down to 5min runtime. Given what I know today it probably could have been <20s.
A database call costs at least 1 millisecond, mostly in network and CPU execution. Consider how much your language can do in 1 millisecond. For example, Ruby can sort an array of about 500,000 elements in that amount of time. It's not always faster to go to the database.

Are there any truly revolutionary/groundbreaking inventions in the world or is everything derived, or combined from past learnings?. iPhone = touch screen + phone + internet. Airplanes = wings = birds…? Maybe the wheel… round rocks?. This evenings random philosophical thought….

Reminds me of the 00's when I mounted the prod server as a disk over SFTP and edited files live. You would literally shout out to coworkers which file you were editing. If you wanted a "big" change, you copied-then-replaced the file. Ah the "good old days". If you're a small co. .
I commit with CMD+Enter git shortcut, no commit messages, straight to production. When I am coding I might be committing 3 times per minute or more etc. Uptime 99.99% no issues. I'm a bit different though 😅. This isn't advice.

I feel like i just inhaled 22 books in three days at @oredev. Exhausted but my brain is running on superpower! Excited to distill my thoughts and impressions and get some writing done about processes, #wayofworking and #agile. #oredev2022 #øredev.
