- WimpWorks v2.39 released: compatible with RISC OS zero page protection
WimpWorks, our RISC OS integrated development environment for desktop app production, has been updated to version 2.39 to fix a couple of bugs that resulted in zero-page access.
The current development version of RISC OS, 5.23, is bringing in zero-page protection to increase the system's resilience to system crashes and causes errors in programs that attempt to access it. Although WimpWorks' access to zero-page wasn't the cause of any crashes as far as we were aware, we welcome the incrased strictness of the system.…09-Oct-2016, 21:05

- First ever review of our software back in 1996. Nothing like that feeling of reading a positive review: appreciation is the most satisfying aspect of development
Acorn User was the premier magazine, and the feeling of seeing my application in print, positively reviewed was amazing. Programmers like to see people enjoying their work, and the recognition of a job well done. I honestly believe this is why open source endures: money is nice, but it isn't everything. -- @jaffa214-Mar-2014, 22:35
- Who said the only intuitive interface is a nipple? RT @anghelides: A handle on good design
Minimal interface isn't a guarantee of simplicity. But designing a product to be easy to use, rather than creating a lot of documentation, is what will succeed in the marketplace. Good design makes use obvious, and behaves the way you expect, and so you avoid providing documentation that's not absolutely necessary.09-Mar-2014, 07:13

The current logo was designed by @ctalibard in the late 1990s. The name 'Jaffa' arose after playing with graduated fills in Acorn's Draw, so it seems fitting that experimenting with the open source vector graphics tool Inkscape gives this possible replacement.22-Feb-2014, 23:00

- WimpWorks demo now BeagleBoard compatible
We're pleased to announce that the WimpWorks demo version has been updated to v2.38, which includes compatibility with the BeagleBoard.

- MeeGo Conference keynote: how it should've been done
The first official day of the MeeGo Spring conference started with a two-hour keynote by Jim Zemlin, Executive Director of the Linux Foundation. While MeeGo is a Linux Foundation project, nobody from the Linux Foundation is formally involved on a day-to-day basis in the management and leadership of the project, which is being left to Intel (and, previously, Nokia). Because of this, Mr. Zemlin stands in as the Linux Foundation's public face for MeeGo.
It did not bode well when the advertised title of the talk, The Future of MeeGo Starts Now was changed to Monday Morning with MeeGo. This event was the opportunity for the MeeGo Project to showcase, and celebrate, last week's 1.2 release (including the N900 Developer Edition). Instead, we got Jim Zemlin talking about the advantages of Linux and open source without connecting the concepts to the MeeGo project and how MeeGo adds value compared with other Linux-based, open source mobile OSes (e.g. Android).…28-May-2011, 08:53

- We go to MeeGo
Please forgive the cheesy title :-) As everyone wrapping up the conference has said, it was a great place; well organised and a fantastic atmosphere. Here are some of my bullet point thoughts:
One thing which struck me, which hasn't been dealt with elsewhere (AFAICT), is the obvious struggles MeeGo is having being an "open" project. For example, during the Compliance talk, I asked Mark Skarpness where the discussions on the specification were happening; as we seemed to get new draft, with a request for comments on a regular basis; where are the discussions happening as to what goes in to those drafts? "meego-dev" was the answer, one I'm not quite sure I believe. On the plus side, my suggestion of an "Extras/Surrounds Profile" seemed like it might have some traction in solving the third-party-dependencies problem.…20-Nov-2010, 16:33

What's interesting is that the small comparison with the iPhone shows how poor hardware (pressure-based touchscreen, bezel around the screen) combines with poor software implementation (separate apps => slow start-up times, little thought to the size of a usable target area) to emphasise the poor user experience. And, frustratingly, how many of the issues raised cut quite close to the bone for Maemo devices too :-(…23-Jul-2008, 10:39

I was invited, but unfortunately had to decline, to speak at the maemo track of LinuxTag 2008.

Below is the crystallisation of some of those thoughts which probably would've formed the basis of a few slides to kickstart discussion.
Where are we?Since November 2005, we've had the N800 and N810; both spaced about a year apart. But whilst the release of the N810 saw its OS backported and released for free for the N800; the release of the N800 saw the 770 dropped in terms of official support.…20-Apr-2008, 19:18

Jaffa Software believe there to be a great deal of life left in the RISC OS platform and will support any solution developed, whether it be the multiprocessing ARM Linux machine with a RISC OS-like GUI or a consortium buying the rights to manufacture Phoebe as only a motherboard. Our products, such as WimpWorks and PICsuite will be updated to work as soon as possible on the new products and we will ensure that our support for existing users will not diminish in any way. We will also continue to develop quality applications for RISC OS and whatever platform results from the ashes of Acorn Workstations.18-Sep-1999

v2.27 of WimpWorks is now available. If you currently have v2.23 or later you can upgrade via the upgrade page. Although this is mainly a bug fix released (OLE on non-StrongEd editors was broken) the way is now clear for some exciting WEMs to be released.28-Mar-1999
