Erich Clar page
[edit]I want to include a synthetic reaction that is known as Clar's reaction. It is of a certain class of cyclic ketones that condense with themselves when heated to 400 C in a mixture of zinc dust and zinc chloride.

I will add references and a description of what it is used for in synthesizing new polycyclic aromatic hydrocarbons.
Judd Buchanan
[edit]This is the second time in the last 10 days or so that an anonymous IP has attempted to update this page to indicate that the subject has died.
https://en.wikipedia.org/wiki/Judd_Buchanan
You undid this update today and Nohomersryan did so as well on August 20. While I cannot find an obituary (which I'm sure you also tried to find), I wonder if someone who's not familiar with editing protocol on Wikipedia is trying in good faith to tell us something. The subject would be 97 years old and his career as an MP spanned from 1968 to 1981, so it's often the case in my experience that sites like Parlinfo (the gold standard) may take a long time to catch wind of the death of an MP who left Parliament 45 years ago. Or perhaps you have a back story that I don't -- although I find it rather unusual that such an elderly person would today be the object of controversy.
I'm curious to hear your thoughts on this. MauriceYMichaud (talk) 23:53, 29 August 2026 (UTC)
- It's probably the same person: the several TAs over the past two weeks have some technical correlations to each other. They are hitting lots of random old-person articles with never a reference provided. I spot-checked a few and found nothing (neither google nor the news-wire of several of their institutions that would surely post an obit promptly. So I blanket rolled-back today's lot and left a level-3 warning. Next step would be to block the TAs, or take other measures, if there's another batch. DMacks (talk) 00:52, 30 August 2026 (UTC)
- Oh I see! While for me the Buchanan article happens to be one of the 5,000 or so that I track, you've seen a broader pattern -- older-person articles and no evidence that they really died. Fair enough! Personally, I've had cases of persons I thought alive had actually died as much as 25 years before, but those were more the exceptions than the rule. So, along with the pattern you've noted, it's better to assume that those updates, while perhaps not in total bad faith, simply cannot be subtantiated. MauriceYMichaud (talk) 11:37, 30 August 2026 (UTC)
- Yup, "verifiability is policy", especially when it comes to biographical details. I guess death hoaxes are an easy pattern of messing around? I saw this particular one on a different old-person article on my watchlist. After realizing that it was not supported, I looked at the editor's other contributions and saw a pattern in this case. Thanks for helping patrol these sorts of things! DMacks (talk) 01:47, 31 August 2026 (UTC)

Tech News: 2026-36
[edit]Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Weekly highlight
- A new format for the Community Wishlist is open for feedback. You can read the proposed ideas on Meta. This new process plans to improve how wishes are triaged, voted on, and prioritized in a way that is transparent and balanced across project families and language editions. This consultation is open for two weeks.
Updates for editors
- The latest release of the Wikipedia Android app includes updates to the Saved feature, bringing the app’s saving experience closer to iOS and Web. The update redesigns the Saved tab with an “All articles” view, removes the default “Saved” reading list, renames reading lists to “Collections,” and modernizes the article-saving experience.
- The Reading Lists feature was enabled for all logged-in users on Bengali, Chinese, Czech and Vietnamese Wikipedias on August 25, after several months as a beta feature. Reading Lists will be available to all logged-in users on Arabic, French and Indonesian Wikipedias on September 1, followed by English Wikipedia on September 14, and all other Wikipedia wikis on September 28.
- At the end of the month, some logged-out readers on Bengali, Czech, Persian, English, and Polish Wikipedias using the Minerva skin on mobile will see an updated navigation bar in an A/B test. The test will compare the current navigation bar with a new version designed to make it easier to find information more quickly. The goal is to determine whether these changes encourage readers to return more often. This experiment will not change the experience for logged-in readers and/or editors.
- Editors who maintain redirects, templates, and categories used on redirect pages now have improved ways for finding and curating redirects. Previously, redirects pages could not be searched. Two new search keywords,
onlyredirects:andwithredirects:, now allow redirects to be searched directly and can be combined with existing keywords such asincategory:,intitle:, andinsource:. - The ISBN lookup tools for generating citations were recently not working because of external service problems. Developers are working on solutions.
View all 30 community-submitted tasks that were resolved last week. For example, an issue where searching for pages by category using deepcatcould return no results or unrelated results has now been fixed.
Updates for technical contributors
- The domain of URLs for thumbnails is changing from upload.wikimedia.org to thumb.wikimedia.org. The old URLs will continue to work for the foreseeable future but MediaWiki will advertise the new domain instead. URLs to other types of media such as original files, videos and transcodes will still be served from upload.wikimedia.org.
- The Wikimedia Math API is now deprecated. These endpoints will be fully sunset by the end of September 2026. Developers who call these endpoints should transition to alternative math rendering solutions, such as the native MathML or MathJax. Third-party MediaWiki installations that utilize the Math extension for formula rendering are required to upgrade to v1.43+ to avoid disruption of service.
Detailed code updates later this week: MediaWiki

Thoughts on a user who has repeated criticism of their articles & editing
[edit]Any thoughts on the page creation record of Skaterlight2013, as an uninvolved admin? They just recreated one of their pages that was deleted a few days ago at AfD; obviously not appropriate but by itself not major. (I have CSD'd it.) However, when I looked at their edit history there are many instances of page deletions and other issues.
I don't see this as ready for ANI as nobody has warned them. I also don't see any of the canned warnings which are appropriate, although I could always create something. Any thoughts on how to encourage them to be more constructive? Ldm1954 (talk) 11:27, 4 September 2026 (UTC)
- Are you seeing a large problem mainly about mainspace page-creation, or about one or two each of many different types of problems? DMacks (talk) 11:45, 4 September 2026 (UTC)
- This is not everything, as a quick count in 2026:
- 2 unattributed translations
- 14 drafts > 6 months unedited
- 8 articles moved to draft
- 5 tagged for deletion
- Ldm1954 (talk) 11:59, 4 September 2026 (UTC)
- N.B., that was a quick count from their talk page. I may have missed some. Ldm1954 (talk) 12:01, 4 September 2026 (UTC)
- Sounds like {{uw-create2}} would be good place to start, with an added bit of custom message emphasizing that there's a long history and that it's wasting a lot of other editors' time having to deal with it. DMacks (talk) 12:05, 4 September 2026 (UTC)
- Good idea, thanks. Busy now, will do it later today. Ldm1954 (talk) 12:23, 4 September 2026 (UTC)

Tech News: 2026-37
[edit]Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Updates for editors
- Add a Link has been upgraded for English Wikipedia users with improved detection of links that have different capitalization. This will help reduce ambiguous suggestions caused by differences in capitalization in article titles, including articles about cultural goods. A second phase of improvements is planned, which will also prepare the feature for release in other languages.
- The Article guidance feature will be enabled by default for junior editors on Simple English and Turkish Wikipedia starting 10 September 2026 following an experiment. Junior editors with 0 to 99 edits will automatically see the feature when they click a red link or use the "Madde oluşturto" option on Turkish Wikipedia to create a new article. The change is intended to help junior editors create higher-quality articles that meet each Wikipedia’s standards. Additional improvements will continue based on the experiment results and community feedback.
- The Pageviews Analysis tool which allows users to compare pageviews across multiple pages, turns 10 years old this year and several new features have been added. They include WikiNav which provides insights into how readers of Wikipedia explore the content, editing stats in Siteviews, the ability to lookup articles belonging to a WikiProject, and support for dark mode.
- A visually simplified Minerva navigation bar is being tested for logged-out readers using mobile web on the Bengali, Czech, English, Farsi, and Polish Wikipedias. The experiment aims to determine whether simplifying the navigation improves reader retention. The test will run from August 31 to September 28, and no action is required from users.
- WMDE Technical Wishes is working on improving auto-generated reference names in VisualEditor. Editors will only notice a slight change starting this week. When adding automatic reference names the numbering will start at
:1instead of:0. Read more on the project page. - All wikis will be read-only for a few minutes on September 23. This is planned at 14:00 UTC. More information will be published in Tech News and will also be posted on individual wikis in the coming weeks.
View all 25 community-submitted tasks that were resolved last week. For example, an issue where Parsoid could mishandle nested nowiki tags, causing content to be lost and displaying unwanted text has now been fixed.
Updates for technical contributors
- Interface administrators can configure gadgets from MediaWiki:Gadgets-definition. The definition format has been updated and no longer requires the
ResourceLoaderoption, as gadgets are always loaded throughResourceLoader. This simplifies gadget configuration by removing an option that is no longer necessary, making gadget definitions easier for administrators.

Just wanted to say thanks!
[edit]Thank you for reverting my edit on Livestreamed suicide a while ago, I was trying to add more details, but I should have checked to see if it was disputed first, I also should have double checked before adding it. I also should have made sure it was notable. Although I personally think it is notable but should have checked for consensus before adding it. RandomNumber-x3lz (talk) 19:10, 8 September 2026 (UTC)
- Thanks for the followup! Typically no harm in being bold with edits at times. DMacks (talk) 03:03, 9 September 2026 (UTC)
Tech News: 2026-38
[edit]Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Weekly highlight
- The Future Audiences team has started a discussion on English Wikipedia about a proposed new experiment to show a temporary notice about the new Google Preferred Sources feature to Wikipedia readers coming from Google. The experiment is to test whether this notice makes visitors come back to Wikipedia more often. Preferred Sources feature lets users choose websites they trust so Google can highlight content from those sources more prominently in Search and AI experiences. We are interested in testing this on other languages that Google supports and would welcome assistance with starting conversations on other wikis. If interested, please reach out to Future Audiences on the talk page.
Updates for editors
- The chat platform Discord is releasing a new self-service framework that websites can use to specify how their links should look when shared on Discord. The Future Audiences team is planning to start using this new framework to improve how Wikipedia links look when shared on Discord, giving better attribution and credit to contributors. The link appearance and behavior won't change in the first phase of this project as we want to first collect some baseline data to assess the impact of future changes. However, if community members who are active on Discord spot any issues, they can reach out on Phabricator or Metawiki.
- The Reader Growth team will be running an experiment to test whether compacting article lead sections on mobiles with the addition of a "read more" button improves reader retention. The test will begin on September 17 on Arabic, Spanish, French, Indonesian, Italian, Japanese, Portuguese, Vietnamese, and Chinese Wikipedias and will run for four weeks.
- All wikis will be read-only for a few minutes on September 23. This is planned at 14:00 UTC. More information will be published in Tech News and will also be posted on individual wikis in the coming week.
View all 28 community-submitted tasks that were resolved last week. For example, an issue where Wikistats for Wikipedias was returning an HTTP 500 error and could not be reached, has now been fixed.
Updates for technical contributors
- Developers who maintain a tool that queries the Wikimedia Commons links tables need to update their code to connect to the new x4 database cluster. The links tables have been moved from the s4 cluster to x4, and will no longer receive updates on s4. The page and redirect tables remain available on both clusters. A wiki replica for the x4 cluster will be set up afterwards. The change is being made because the s4 cluster has grown too large to operate efficiently. You can read more.
