Great video that goes beyond the usual (i.e. not helpful) buzzword bingo-level and talks about the challenges of using micro services.
I had not planned it, but this is a nice follow-up to my previous post about conventional wisdom.
Very interesting talk that puts emphasis not only on technical but also organizational and social aspects.
A not really technical talk, at least not in terms of details. But Benno, who comes from the FreeBSD side, covers a lot of stuff from the conceptual side. My verdict: Absolutely worth it.
Another very interesting talk of Simon Sinek, this time at Google. The full title is
“The Finite and Infinite Games of Leadership: Leadership, Business and Finding Purpose in the Workplace.”
The following points were interesting for me:
- Time code 7:00 : Infinite players do not compete with the competition but themselves. This has an awful lot of strategic implications.
- Time code 16:55 : Dealing with personal objectives and bonuses. Also see my post about this very topic.
- Time code 33:00 : Why are small companies usually more innovative than big ones?
For setting up VLANs in my home network I basically followed the tutorial from Crosstalk Solution on YouTube:
The result, however, was not working as expected. As it turned out the critical difference was that I have my pfSense firewall running virtualized on VMware ESXi 6.5. By default the latter “removes” VLAN tags.
But it is very easy to change this and not even a reboot is required. So here are the steps you need to perform:
- Log in to the admin web UI of ESXi
- Go to the network port groups and open your internal network
- Open settings for internal network
- Change VLAN to 4095
- Save change
That’s all 🙂
Mr McEnerney presents a really good “strategic” approach to writing in a professional context. On the one hand nothing really new, but the way it is presented and details being put into context, make this a wonderful framework for me.
In particular it became even clearer to me why knowing a lot about a subject often makes it more difficult to write about it or discuss things with non-subject-matter-experts. This is also described nicely in the course description for professionals.
And finally I want to direct your attention to this nice blog post about a personal encounter with Larry McEnerney.
While watching the video below, I was intrigued, when this interview questions was discussed (timestamp 56:30-57:35).
It made me think about my response, had I ever been asked the same. And it did not take too long before the answer was clear: the B-Tree. There is a very good section on it in Martin Kleppmann‘s book “Designing Data-Intensive Applications“. And I highly recommend this book anyway.
But as a starting point on B-Trees the following video is also quite helpful:
A bit different form what I usually post, but a fascinating topic.
