Yes, just try to put up the example code, and directions on how to run it in a web site a couple of days before the chat, and ask your audience to try the example prior to the chat. That way they can experiment and play with what you're going to explain instead of having to grasp it in abstract. Trying to get all the details of dpi without experimenting with it beforehand can be tough. > I will try to show a preferences plug in as example. > Is the bug #695 solved somewhere? No, but I made a quick hacky patch for you! :-) It's not as clean and tested as I'd like, but OTOH it would not surprise me if it ends being a good solution.

dillo chat in Logroño/La Rioja/Spain

by Diego .

Hello. I am Diego Sáenz. I use this mail address now (I had mail problems and lost some mails, but i have read them in the list archive). I am associate of AULIR (Asociacion de Usuarios de GNU/Linux de La Rioja) a spanish LUG and will give a chat about how to wrote dillo plug-ins. I will explain a few the dillo internals too. There are not very much programers in AULIR(one of them program anjelica.sourceforge.net) but i will try to wake interest about dillo. Any advice for the chat? I will try to show a preferences plug in as example. Is the bug #695 solved somewhere? i think i will need to use it for a feature of the plug in. Diego. ps: i hoppe that this do not seem spam* *

Etc. This is a very appropiate question. :-) The campaign to help Dillo survive has not attracted new funders, and the donations amount near EUR 250. This clearly doesn't change a bit the project status. People in the embedded market want a small featured browser, but don't want to invest in it. This is: if we develop it they'll use it, but there's not much interest in funding the development. From a business perspective it makes sense. Investing in Dillo to make a full featured embedable web browser of it, is a three years plan (and who knows what the Web will look like in three years). Now if they only need an embedable web browser that evolves into a full-featured one. They could start deploying it in a year. This is a business opportunity indeed, but it depends on a company having a client demanding it; here using Dillo fits the bill. On the technical side, the port to FLTK2 is almost finished, and has been a surprisingly smooth transition, without surprises, going on as planned (except that we planned for some surprises!). OTOH development is progressing at very slow pace because we, the core developers, can't work full time on it, and spare time is scarce. From a community perspective, it's interesting to notice that there's a need for a lightweight web browser (Think of OLPC, firefox's users demands for less features and smaller footprint, help systems, a thin client for web apps., the embedded market: cell phones, PDAs etc). Now, if not enough users are willing to support development with money, the funding may only come from the business area, but business don't invest with regard to users' needs, but with regard to ROI. BTW, another source of funding is governments, but in seven years, not a single email has arrived from that source ;-). There we are. -- Cheers Jorge.-

It has shaped very well! A few observations: * I'd put FLTK2 instead of FLTK FLTK1 is different and Dillo doesn't compile with it. * FLTK2 comes with text antialiasing and UTF8 A couple of features already working in dillo-fltk2! (this may be pointed up there) * For further information, and contact, please point them to my email address (jcid(a)dillo.org) > Do you think to contact the company which contacted you three years ago? Most probably yes.

I hope you find funding. Thanks for the corrections. One important precision: the dillo project needs at least two core developers working on it fulltime. Not only me. If there's only one person working full time on it, it's not enough to keep the pace of evolving technologies.

I find this paragraph misleading: "Alternatively, Cid says he will release the FLTK2 port if he finds enough funding to be able to continue working fulltime on the port himeself. He said, "Given the current situation, the best option seems to be to remain closed until funding happens." and it's not true.

I'd be willing to put some time in on the project. No FLTK2 experience, but it's yet another wretched event-driven-interface widget thing (yawediwt), so how hard can it be?

It's already going on and it may have some impact. FWIW, some years ago a very big cell phone company tried to hire me and Sebastian (IIRC) to develop the browser for their cellphone. Not Dillo, but a propietary one. Now that years have passed, and that they left the propietary browsing avenue, it may happen. Who knows? -- Cheers Jorge.-
