Jestem na świeżo po doświadczeniu nowych możliwości. Prowadziliśmy w mijającym tygodniu warsztaty strategiczne dla pięćdziesięciu osób. Spotykaliśmy się w tak dużej grupie, przez kolejne trzy dni. Uczestnicy byli z całego kraju. Każdego dnia warsztatowego spędzali poranki na zajęciach, a popołudniami wykonywali swoją normalną pracę.

Origin of the Shell

Louis Pouzin: "I felt that commands should be usable as building blocks for writing more commands, just like subroutine libraries. Hence, I wrote "RUNCOM", a sort of shell driving the execution of command scripts, with argument substitution".

To write well is to think clearly

To write well is to think clearly. If you can think clearly, you can find something worth saying. An ideal place to start is thinking through what bothers you most in life. Then write a post that thinks through the issue. Why? The best

Clean Code in practice: Three tips from Uncle Bob

If changing state, change state of the owning object Much of the need for output arguments disappears in OO languages because this is intended to act as an output argument. In other words, it would be better for appendFooter to be invoked as report.

It's harmless if reporters and know-it-alls dismiss your startup. They always get things wrong. It's even ok if investors dismiss your startup; they'll change their minds when they see growth. The big danger is that you'll dismiss your startup yourself. I've seen it happen.

Containers and virtual machines

Containers are lightweight, but in terms of maturity of the technology, and security, they are considerably behind VMs. To get the best of both worlds, use containers inside virtual machines. More often it would be more expensive to redesign the application for containerization than
