Carsten and I are talking about using Tizen (including Tizen IVI full images which include developer tools) as the developers working distro.

Current problem we are talking about is the developers' working distro, not the Tizen runtime:) thanks - jf.ding On Mon, Sep 23, 2013 at 06:23:37PM +0900, Carsten Haitzler wrote: > On Mon, 23 Sep 2013 08:28:06 +0300 Leon Anavi <[email protected]> said: > > > Hi Daniel, Carsten, All, > > > > On 2013-09-23 03:46, Daniel Juyung Seo wrote: > > > On Mon, Sep 23, 2013 at 8:53 AM, Carsten Haitzler > > >> imagine if all the engineers and executives etc. at bmw drove > > >> fords because "bmw's can't manage to get us to the office without > > >> breaking down". > > > > > > Awesome analogy. > > > > > > I am also against dropping 32 bit system support for dev tools. > > > > > > I bet many people I know use 32 bit system yet. > > > > > > > The example with the cars is nice but I don't think it's very > > appropriate.
