(35) Enabling New Hardware in U-Boot – Jon Mason, Broadcom Ltd. – YouTube

Posted by jpluimers on 2018/07/20

Lots of interesting information, especially these discussions where Alexander Graf chipped in:

The hand off of the boot loader to the actual OS payload. The payload and U-boot are in memory running at the same time. The payload can call back into U-boot through the uEFI API that U-boot implements so that the payload provides extra drivers enabling for instance a subsequent graphical stage (splash screen, menus, etc), more hardware access and so on. You even could pass ACPI tables through U-boot to the payload and help shooting yourself in the foot.

Important aspects for upstreaming:

  • keep commits short so they are easy to review
  • make sure patches are always rebaseable for each and every commit set (so it compiles throughout)
  • this tremendously helps doing a git bisect
  • it makes adding features that other parts depend on hard: you need to think on chicken & egg situations in advance

Looking at [WayBack/dev/lawyer Open Source License Business Perception Report it seems that the [Archive.isApache License 2.0 causes the least pain and confusion for lawyers.

Delphi Community Edition available: good move for Embarcadero, but be careful how much revenue you make

Posted by jpluimers on 2018/07/19

On [WayBack] Delphi Community Edition available: – Uwe Raabe – Google+, the links to the [WayBackEULA, [WayBack] FAQ and [WayBack] Feature Matrix were shared.

In summary (read the G+ thread for more), the Delphi Community Edition is a web-installer of version 10.2.3 feature equivalent to the Delphi Professional Edition.

I think it is a good move to make Delphi more accessible to many more people.

A few restrictions apply, for instance there is also a C++ Builder Community Edition equivalent to the C++ Builder Professional edition, but you cannot install them on the same system at the time time.

Also, you cannot move around the command-line compiler to a different system (for instance a build-machine for Continuous Integration purposes).

The financial restriction that applies can be summarised as this: When the revenue you make during the year exceeds USD 5000 you have to stop using the Community Edition license.

Note that this is about revenue, not about income (which many define as “net of revenues and expenses”), and does not mention the revenue source, so watch this during the years you use the Community Edition.

Furthermore, Embarcadero indicates they collect information about your use of the Community Edition, but the [WayBack] privacy statement is not clear how.

All in all I hope this move attracts fresh people into the Delphi community.

The heise – the German flagship IT journal – likes it too: [WayBack] Delphi und C ++ Builder als Community Edition | heise Developer (via [WayBack] Some nice PR … Embarcadero-konfektioniert-Delphi-und-C-Builder-als-Community-Edition-4115563… – Roland Kossow – Google+)
