Honestly I learned the most (and became a much better dev) when I reinvented the wheel.
Built a (simple) ORM instead of just using NHibernate (was a mistake.) Implemented own sorting algo thinking it would do better than built in (it did not.) Built own charting library. Etc
All were worth it!!

It's good to reinvent the wheel sometimes!

Great post by Matthias Endler.
It helps understanding how wheels work, how you can fix them when broken, how to make better wheels if really needed, or how to find creative use cases for wheels by thinking outside the box.

"Clever engineers write clever code. Exceptional engineers write simple code."
100% agree with this. There are rare exceptions that call for clever or innovative, but most of the time you think you're being clever you're just leaving a trap for a future you.

Any company whose mission is to “to ensure that artificial general intelligence benefits all of humanity” would be ecstatic about a capable open source model like Deepseek released.
Any company which has a mission of making money off closed-source models would be devastated tho.

The only way to turn it off is to
1. Contact your Google Workspace administrator to

3. Cross fingers

Google auto opted in *every* paying Google Workspace user to Gemini. Also adding a nice increase in price, even though no one opted into it.
You cannot turn off / opt out.
Except... if you open a support ticket.
Only then does Google enable the setting to turn it off!

At my previous job, I joined and inherited an (IMO) over engineered CI platform that had been neglected for a long time. In fairness, it still worked very well, but it had lots of low hanging fruit in terms of bug fixes, new features, and VULN fixes (oh god the number of open VULNs)
