[haiku-development] Re: ProcessController scheduler mode naming (Humdinger)

Tue, 2014-03-25 22:45
Hi! I'm sorry that I have opened another can of bikeshed... How about this: Since the current Low latency setting is the default setting of the scheduler anyway, why not remove it from the ProcessController menu and just keep the Power-saving mode in there. That would also comply better to the checkmark nature of the menu item (right now the two checkmarkable menu items are mutually exclusive, i.e. it's really a radio button setting). ...

This may not be all too helpful, but I wouldn't put too much worry into this, pick something that's fairly descriptive, then write a good Getting started guide that explains in detail what all the settings do. Just my 2 cents. And sorry for the top post, I am still configuring my mail client to properly include messages in replies. Daniel ...

That's less technical but still accurate. ...

Hi! ProcessController offers two scheduler modes Low latency and Power saving. Anyone against renaming those to Performance mode and Power saving mode? Opinions are tied currently 1:1. Anyone else? For the German translation, we already opted for Performance-Modus. Niedrige-Latenzzeit-Modus isn't anything I expect the average user to grasp... I'm not a native English speaker, so I rely on others' opinions in this respect. ...

[haiku-development] New and updated EFI branch (Fredrik Holmqvist)

Mon, 2014-03-24 16:45
This is mostly for devs and potential GSoC students. I've done some minor cleanup to the EFI code and updated to a new Haiku revision to leave it in a better state than it has been siting in for a few months. As I didn't want to change history in the efi_pm branch I've created a new efi branch[1]. Consider the efi_pm branch obsolete. It builds and runs, if you disable 'treat errors as warnings' for src/system/boot. This can be done in build/jam/ArchitectureRules by ...

It's the commonly used compression algorithm in ZFS. See benchmark comparison here: (in Web+ that table looks messed up though) I agree that this would be better for storing it on disk, or maybe LZO. The problem is: That means larger files to transfer over the net, as compressing ...
