Website Caching (again)and fall-back
by Martin Owens 14 Mar '18

14 Mar '18

Hi all, This is a general notice, I've switched on nginx caching for non-logged in users. 95% of all requests are to non-logged in users. Caching is set to 1 hour, if you update a cms page, upload a new resource or make a new release, there WILL be a delay to some users getting the new information. We are closely monitoring the web server and tweaking the settings as needed. Average request times have be 0.9s-1.1s but some days see spikes to 5s (for the whole day) so we want to try and reduce the common load. Page loads for HITs are down to 120ms, compared to 980ms for a MISS. I've also removed cmsplugin-history which takes up a lot of RAM. There may be some holes in the cms, so let me know if you hit one. Page caching in nginx means that if the website goes down, nginx will keep giving our users a website as much as possible. So we may see a slight improvement in fall-over, certainly for normal users. Best Regards, Martin Owens

Quick 0.92.3pre0 test needed (was Re: inkscape-0.92.3pre0 source tarball now available)
by Bryce Harrington 14 Mar '18

14 Mar '18

I am in the process of finalizing 0.92.3 for release. Would someone mind downloading the tarball, building it, running the program, and using it a bit as a quick sanity check? Download from: https://inkscape.org/en/release/0.92.3pre0/ Eduard and I have built and run it, and so I'm not expecting there are any issues, just looking for a quick thumbs up that it works as expected for a third person. Thanks, Bryce

Question about an Issue #168 "Make Issue Responsive..."
by Tonya Sims 12 Mar '18

12 Mar '18

Hi all, I'd like to work on this patch https://gitlab.com/inkscape/inkscape-web/issues/168 and have a few questions. 1. Is this non-responsiveness happening on all pages? 2. Can you direct me to the URL where it's happening? 3. Do we have any screenshots of the issue? Thank you, Tonya

Prerequisites for using Inkscape UI free, GSOC 2018
by Kuntal Majumder 11 Mar '18

11 Mar '18

Hi, I am Kuntal, some of the people might know me from IRC. I was looking into the GSOC 2018 ideas list. Loved the idea of making Inkscape go UI free [1]. I would love to give it a try, I have used CMake to compile programs in past, but never wrote a CMakeLists file. I was also working on my own build system [2], which is currently not that nicer, well I am yet to learn how to write parsers, :P. Also whenever I used Inkscape, I used to jump to and fro from Inkscape to Calculator to get the correct ratios, wouldn't that be better if we can put expressions inside text-boxes and they evaluate by themselves. If the previous mentioned idea is viable for GSOC, I would love to pitch for it. Thanks Kuntal (hellozee) [1] http://wiki.inkscape.org/wiki/index.php/Google_Summer_of_Code#P5._UI-Free_I… [2] https://github.com/hellozee/Cook

Eager Python Developer - GSoC
by Tonya Sims 11 Mar '18

11 Mar '18

Hello everyone! My name is Tonya, I'm a junior to mid level Python developer and plan on applying for GSoC I downloaded Inkscape on my Mac and played around with it. A very cool application! What are your most urgent needs? Are your extensions built in Python? I was trying to brainstorm some ideas for a new extension and may need more time unless there's something you could suggest? Also, I'm learning Django and could help out with the website, let's say a new bug tracking system (not that you need one) but just brainstorming. Anyways, looking forward to everyone's replies and will start working on my application. Cheers, Tonya Sims

Hackfest update
by Máirín Duffy 08 Mar '18

08 Mar '18

Hi everyone, I wanted to give you a heads up about a couple of things regarding the hackfestsite - - Onthe Monday, Red Hat is also going to host a SpinachCon event on the other side of the space we'll be in. It's a 4 hour event (from 1-5 pm IIRC) where free software projects can come and have their software usability tested. The organizers (including Deb Nicholson) would be more than happy to test Inkscape as part of the event if there's any interest in that. If there are specific components you'd like tested, I can help create a testing plan. - There may be another co-hosted event in the morning on Monday, still sorting the details out. - On the Tuesday and Wednesday, Red Hat is also hosting an event that will involve a workshop and hacking on amedical image processing system that we're working on with Boston University and Boston Children's Hospital. It's a really cool project. If anyone attending has an interestin learning more, you are more than welcome to get involved. I don't expect either event to be disruptive to the hackfest; it's a large space and we have two floors and a variety of different areas to work inand a lot of seating. I just wanted to let you know ahead of time, especially in case you wanted to take advantage of SpinachCon testing.If you have a preference towards the type of space you'd prefer (large conference room with door; open meet up space; lounge-y type area with couches and tables and chairs) I can note in our reservation now that's the part we'd like for the Inkscape hackfest; if you're not sure I can give youa tour when you get here on the Monday morning and we can figure out which end of the office to claim. Cheers, ~m

Can you update me on how things are going right now? Are there particular things you're stuck on? I probably don't know enough to offer advice myself but maybe can suggest someone that can. If the issue looks like it can't be solved quickly, perhaps for testing purposes it might help to add one or two environment variables to turn on/off pieces of the UI or codebase that are causing problems. So if someone testing the renderer can do without the toolbar, they can disable it at runtime? Something like that? In the coming weeks I'd like to produce a testing build of Inkscape, so if there are some (ugly) ways to enable testers to work around the performance bug that would help.

Running the build on mac
by Elizabeth Kirby 07 Mar '18

07 Mar '18

Hi all, I'm trying to get inkscape to run on the mac. I downloaded a zip of the code (recently) & installed a handful of packages using ports. There was one dependency that I couldn't get to resolve using any ports package, which is libsoup. I installed it using brew & then the code will compile. It will run, but not correctly. I put in a symlink from /usr/share/inkscape to my build tree share directory & it does load the items on the right & left sides, but without any of the images that tell what they are. I would rather not have a symlink in /usr/share, but instead just have the build read from the build tree. Are there any people developing on mac out there that can share their configuration & settings & tell me what parameters need to be set & where? Thanks, Beth

This is super cool! I specially loved the CSS animation of the weight of the text when the cursor hovers over a button. This seems to replace Tav's opentype features selector via a GTK font-selector dialog. It also seems that we could have the innitial variable fonts support in inkscape basically hooking up to this newly improved GTK dialog. Naturally, that would require Inkscape to rely on a pretty recent version of GTK.
