Support for Chemical table files [Cross-posted to Commons-l]
by Rainer Rillke 08 Jul '14

08 Jul '14

As of now, images of structural formulas have to be created using third party software and converting the output to SVG or PNG. With MolHandler[1] we aim for a solution capable accepting and rendering chemical markup files and providing a web-interface for easily creating, modifying and re-mixing formula files. This does not only make re-using existing structures easier and simplifies creation of structures, moreover it allows Wikis to adopt a unified style for rendering these structures, makes structures searchable (sub-structure search) allows pulling, pushing and verifying data from big databases like ChemSpider and PubChem. In the future we plan to enable support for spectra and more sophisticated file formats to have at least some minimum support for chemistry-related Wiki-works. I am currently looking for features you would find helpful and therefore created a test wiki[2] at which you can create user accounts. A non-exhaustive list of features is available for raking by drag&drop. Or just write here what you at least want, what you would like to see soon and what is less important to you. -- Rillke [1] https://www.mediawiki.org/wiki/Chemical_Markup_support_for_Wikimedia_Commons [2] http://mol.wmflabs.org/

Multimedia's EventLogging consumption
by Gilles Dubuc 08 Jul '14

08 Jul '14

Hello analytics, My last round of reducing our EL consumption was right after the launch of Media Viewer to all wikis. I see now that the per-schema graphite stats are back: http://graphite.wikimedia.org/render/?width=586&height=308&_salt=1404769845… Is that a reasonable amount of EventLogging usage for MediaViewer? Or should we do another pass of reducing our usage?

JS upload management libraries that might be useful for UploadWizard's refactoring
by Gilles Dubuc 07 Jul '14

07 Jul '14

While doing the research for tomorrow's UploadWizard refactoring meeting, I ran into those JS libraries that seem very promising: https://github.com/blueimp/jQuery-File-Upload Demo: http://blueimp.github.io/jQuery-File-Upload/ https://github.com/Widen/fine-uploader Demos: http://fineuploader.com/demos.html They are both very actively maintained and cover a lot of the core upload functionality needed in UploadWizard. I think we should review those in detail, as they might be very interesting options for UploadWizard.

WMF receiving contributions on hard drives?
by Gilles Dubuc 03 Jul '14

03 Jul '14

Hi all, Fae brought this up: https://bugzilla.wikimedia.org/show_bug.cgi?id=67477 Clearly, mailing the hard drive would be the most efficient way of transferring the data. If the hard drive can make it to close enough to our data center's network, anyway, which might have security implications. Is there any precedence to doing something like this?

Media Viewer Update
by Fabrice Florin 02 Jul '14

02 Jul '14

Hi folks, Here’s an update on the Media Viewer project, with new metrics and remaining issues. 1. Weekly metrics: a. Disables: Global disable events - logged in users 37 (3%) Global disable events - logged out (anons) 1,126 (97%) Total disable events 1,163 (100%) See the new spreadsheet for disable metrics (1) — and its corresponding opt-in/out dashboard (2). These results were collected on June 30, 2014. Since we just rolled out this new metric and dashboard, we don’t have any data to compare it to yet. And we don’t know either what’s an acceptable disable rate for this type of feature. For now, here’s one way to put these numbers in context: total disables represent 0.0049% of image views that day. Comparing English and German disable rates is also informative, as shown in the spreadsheet: English users are disabling a bit more than German users as a percent of image views (0.0064% vs. 0.0048%). It’s also worth noting that a larger percentage of English logged-in users (10%) disabled Media Viewer, compared to their German counterparts (2%). This new metric gives us another view on overall acceptance of this feature. It is not perfect, but seems more objective and less time-consuming than the short-term surveys we used to collect feedback in recent months. b. Surveys: As discussed, we have now removed Media Viewer surveys in most languages — except for English and German, which will be turned off next week. To wrap up our survey reports, we added the last weekly approval rates as of June 23 on this updated worksheet (3). Overall, we observed an upward trend on most wikis last week -- especially on the English Wikipedia, with weekend approval growing to 52% (vs. 38% ‘nos'). These surveys provided invaluable feedback to identify the most important issues across all user groups. Now that we have addressed most of these issues, we plan to end these surveys next week. 2. Top outstanding issues: * More info above the fold (3%) > click on truncated info to see more * More image sizes (8%) > add more sizes in download panel (we are doing a quick survey now to better understand what’s needed) * iOS issues (iPhone/iPad) (1%) > we’re punting on these, because the new tablet redirect only impacts a tiny user group now 3. Top issues addressed this week: * Want full resolution images (2%) > show tooltip when they click on images * Show more attribution + license info (2%) > show attribution credits in download tool * Can't find download (3%) > add text label ‘Use this file’ * Can't find Commons link (2%) > move Commons link to the left * Too slow (2%) > ask ops to implement back-end image rendering 4. Community RfCs: We are now monitoring 3 Requests for Comments on these sites: * English RfC (4): Unfavorable so far, with 48 responses to disable for logged-in users, 5 to enable (similar ratio for logged-out) — ends on July 7. * Commons RfC (5): Too soon to tell, with 4 responses to disable for logged-in users, 3 to enable (similar response for logged-out) — just started June 27. * German RfC (6): Hasn’t started yet, but 10 people now think it’s needed — so it’s expected to start soon. We will send another update about the RfCs in coming days. Please let us know if you have any questions about this update.

Media Viewer is now live on all wikis
by Fabrice Florin 30 Jun '14

30 Jun '14

Hi folks, We're happy to announce that Media Viewer is now live on all wikis hosted by the Wikimedia Foundation! Media Viewer is testing well on all remaining Wikipedias (e.g.: Chinese, Arabic, Hindu, Indonesian, etc.) and sister sites (e.g.: MetaWiki, Wikibooks, Wikiquotes, Wikiversity, Wiktionary). The multimedia team worked hard in the last few weeks to develop a range of final features, in response to frequent community requests. We hope you will try them out and let us know what you think on the Media Viewer discussion page (1). 1. Features on All Wikis These features are now available on all wikis as of today: * View original file (#630) * Scroll down to see more info (#697) * Show Commons link to logged out users (#429) * Easy opt-out for registered users (#703) * Opt-out for anons (#704) You can test these features on this Featured Pictures page. (2) 2. Features on MediaWiki.org only: These features are now available on MediaWiki.org and will be deployed to all wikis in coming days: * Make it easier to find image information (#706) * Prominent links to different image sizes (#664) * Add more tooltips to Media Viewer (#546) * Disable MediaViewer for certain images (#511) * Track 'View original file’ and ‘Commons link' clicks (#715, #726) * Track Media Viewer Opt-outs (/#558, #675) You can test these features on this demo page (3) — and learn more on the updated help page (4). 3. Features in development Other tasks in development or analysis include: * Show attribution credits in download tool (#598) * Make 'Commons link' and 'Use this file' more discoverable (#732) * Click on image in Media Viewer to help view original file (#712) * Improve Media Viewer UI on tablets (zoom/scroll) (#716) * Remember the last selection for ‘Use this file' (#660) You can view more details about these features on our planning site. (5) 4. Feedback We keep getting generally positive feedback worldwide, with these latest results: (6) * A majority of global respondents find the tool useful (60% average across surveys) * Cumulative approval by language: English 29%, French 70%, Spanish 78%, Dutch 59%, Portuguese 81%, German 28%, Hungarian 62%, Catalan 71% * Daily approval rates have increased on English Wikipedia from about 23% a day after launch to 39% two weeks after launch (and German approval has also increased from 23% to 56% in the same period). * We anticipate further approval increases on these sites, as more new features get rolled out in coming days, based on community feedback. We are also starting to track the opt-out rates to see how many people turn off Media Viewer in their preferences. As of June 16, about 875 users had disabled this feature on the English Wikipedia, two weeks after launch: this represents about 0.34% of all registered users who viewed images on the site since launch. We are sorry that this small minority of users don’t like the tool, but we are glad that so many other users are finding it useful. Please let us know what you think of these new features on our main discussion page (1). Which do you like most? least? Are there other must-have features that need to be developed right away, before we move on to other projects? Thanks to all the community and team members for all you’ve done to make Media Viewer possible. :) Onward!

Event Logging Throughput Alarm on 25 of June
by Nuria Ruiz 25 Jun '14

25 Jun '14

Team, We had an spike on EL yesterday nite that was caught by our alarms. The spike can be seen here: http://graphite.wikimedia.org/render/?width=588&height=311&_salt=1403681192… As far as I can see it caused no service issues so there is no need to notify users. I am cc-ing the Media team on this e-mail cause from a brief inspection of events it looks like they started to log at a higher rate on the 25th. Thanks, Nuria ---------- Forwarded message ---------- From: <icinga(a)neon.wikimedia.org> Date: Wed, Jun 25, 2014 at 4:46 AM Subject: ** PROBLEM alert - tungsten/Throughput of event logging events is CRITICAL ** To: nuria(a)wikimedia.org ❤❤❤❤❤ Icinga ❤❤❤❤❤ Notification Type: PROBLEM Service: Throughput of event logging events Host: tungsten Address: 10.64.0.18 State: CRITICAL Date/Time: Wed Jun 25 02:46:22 UTC 2014 Additional Info: CRITICAL: 7.14% of data exceeded the critical threshold [500.0] Love, Icinga

Summer contractors for Multimedia
by Rob Lanphier 25 Jun '14

25 Jun '14

Hi folks, I just wanted to provide a brief (and belated) announcement regarding some added help we've enlisted over the summer on the Multimedia team. Brian Wolff has been doing little bits of contracting work over the course of his school year (as well as a lot of volunteer development), and this summer will be doing a lot more contracting work. He plans to spend his time taking out various bugs in all multimedia components. He's been at it for a few weeks now, and has already made a lot of headway. Neil Kandalgaonkar will be working with us this summer on unit tests for UploadWizard. Neil originally wrote and maintained UploadWizard as an employee of Wikimedia Foundation between 2009 and 2012. We're delighted to have him back for a little while to help bootstrap our work on improving UploadWizard. Welcome guys! \o/ Rob

Multimedia Next Cycle Plan
by Fabrice Florin 18 Jun '14

18 Jun '14

Hello everyone, This week, the multimedia team completed its planning for our next development cycle, which started on June 11 and ends on July 22, 2014. Here are our plans for this 6-week cycle, which are informed by results of our last cycle. 1. Last Cycle Results Here are our key accomplishments from the last cycle, which ended on June 10: * released Media Viewer on most large wikis (25 million image views/day !) * developed metrics system to track image views, key actions, image load and network performance * collected 13k survey responses (~60% approval) and talk page feedback, processed comments to identify key issues * developed final features and bug fixes based on community feedback (e.g. view original file, file page link, metadata visibility) * solved critical bugs and technical debt for other multimedia tools (e.g. Image Scalers, GW Toolset, TimedMediaHandler) * started Upload Wizard project: planning, bug fixes, code review, refactoring, metrics, user feedback, designs * started Structured Data project: planning, discussions, research, code review * defined annual plan for multimedia in 2014-15 We completed about 112 points in the last 6-week cycle (vs. 128 points in previous 6-week cycle, with 4 engineers instead of 3). That's about 19 points per week (or 15 points of planned development per week, excluding scope increase and meetings). Our estimated capacity for this new cycle is about 10.5 points/ week of planned development, as two of our engineers are taking vacations this cycle. 2. Next Cycle Goals For this next 6-week cycle, we plan to wrap up the Media Viewer project and start work on our next two big projects for the coming year: Upload Wizard and Structured Data — while reserving about a third of our time to address critical bugs and technical debt for other multimedia tools. This cycle, we propose to invest our time evenly between these main projects: * Media Viewer - fix critical bugs, important feature tweaks (to address latest community feedback) * Upload Wizard - planning and first steps (bug fixes, metrics, feedback, discussions, designs, code review, unit tests) * Critical Bugs / Tech Debt - fix serious issues that need quick solutions (e.g. image scalers, GW toolset, timed media handler) * Structured Data - planning with Wikidata and first steps (mockups, specifications, discussions, code review) The Current Cycle wall now includes separate columns for Media Viewer (14-22 points), Structured Data (9 points), Tech Debt (18 points) and Upload Wizard (14-22 points). We don't expect to complete all these tasks in this cycle, as they exceed the anticipated team capacity for this period, but wanted to have the flexibility to choose between different options as circumstances dictate. For an overview of the tasks we are planning on, read below or visit this updated cycle wall: http://ur1.ca/h7w5s 3. Media Viewer For our first two weekly sprints, our focus will be on these Media Viewer improvements, to address community concerns on English and German Wikipedias: * View original file (#630) * View different image sizes (#664) * Scroll down to see more info (#697) * Show Commons link to logged out users (#429) * Instant Opt-out (#703) * Opt-out for anons (#704) * Add tooltips to Media Viewer (#546) * Disable MediaViewer for certain images (#511) The features above are expected to deploy on all wikis tomorrow. Many of them are live already on Media Viewer sites, and we are starting to hear positive responses on our talk pages, with survey approvals trending up for English and German users. Other tasks in development or analysis include: * Make it easier to find image information (#706) * Show attribution credits in download tool (#598) * Make 'Commons link' and 'Use this file' more discoverable (#732) * Improve Media Viewer UI on tablets (zoom/scroll) (#716) * Remember the last selection for ‘Use this file' (#660) * Track Media Viewer Opt-outs (/#558, #675) * Track 'View original file’ and ‘Commons link' clicks (#715, #726) To learn more, click on the relevant cards in our current sprint wall: http://ur1.ca/gtyrp 4. Upload Wizard We have started planning and development on Upload Wizard, which will be our main user-facing project in the coming year. For now, we are focusing on metrics, feedback, bug fixes, unit tests, code refactoring and a few small user interface improvements. Here are some of the tasks we plan to take on this cycle: * Metrics & Funnel Analysis (#305, #541, #603, #587) * Analyze user feedback for Upload Wizard (#624) * Code Refactoring Plan (#344) * UI Improvement Plan (#342) * First Unit Tests (#70) * Show progress bar during upload (#651) * Upload Wizard FAQ links (#625) To learn more, check out this updated project page: https://www.mediawiki.org/wiki/UploadWizard 5. Structured Data We are starting to work with the Wikidata team to plan this project, which aims to provide machine-readable data for media files on Wikimedia Commons. Our main activities this cycle include: * Planning meetings with Wikidata * Mockups and schemas for a new metadata structure * Community discussions to understand user needs and workflows * Definitions for a high-level class for image metadata To learn more, check out this new project page: https://www.mediawiki.org/wiki/Multimedia/Structured_Data 6. Critical Bugs / Tech Debt We will continue to allocate about a third of our time to address urgent bugs and technical debt to gradually improve our multimedia infrastructure. Here are some tasks we are considering for this cycle: * Create poolcounter group for expensive thumbnails (#623) * Pre-render thumbnails in all sizes on the back-end (#301) * Fix TimedMediaHandler resource loading (#543) * Push messages to logstash from JS (#127) * Create vagrant role for Commons (#632) * TimedMediaHandler Improvements (e.g. #729) * GW Toolset Improvements To learn more, click on the relevant cards in our Technical Debt wall: https://wikimedia.mingle.thoughtworks.com/projects/multimedia/cards?favorit… For a roadmap of our goals for these projects in future cycles, visit this planning page for 2014-2015: https://www.mediawiki.org/wiki/Multimedia/2014-15_Goals Please let us know what you think of this plan — and if you have any questions or comments. You are invited to post your feedback on this mailing list, or on the discussion for this cycle plan page: https://www.mediawiki.org/wiki/Multimedia/Meetings/Next_Cycle_3_Q4_2013-14 We look forward to discussing these topics with some of you in coming weeks. Onward! Fabrice - for the Multimedia Team _______________________________ Fabrice Florin Product Manager, Multimedia Wikimedia Foundation https://www.mediawiki.org/wiki/User:Fabrice_Florin_(WMF)
