If you find this page on a site that is not Wikipedia, you are viewing a mirror site. The page may be old and the owner of this page may not have a relationship with sites that are not Wikipedia. The original page is located at http://simple.wikipedia.org/wiki/User_talk:Chenzw.
Chenzw is trying to take a short wikibreak and will be back on Wikipedia soon. For urgent issues and those related to ChenzwBot, please send an email. Most likely, however, Chenzw will not be able to keep away from Wikipedia for that long, and will probably be back a lot earlier while making some small edits every once in a while anyway.
If you intend to ask me for user rights (e.g. rollbacker, patroller):
If you have not done so, please add your request to this page instead. Requests for rights will be processed on that page.
If you have an ongoing request, please wait a while more. WP:RFP is closely monitored, and administrators may decide to put requests on hold in order to allow for more time to evaluate editing activity.
Unless under exceptional circumstances, requests made here will be ignored. Thank you for your understanding.
Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
WebM video files have smaller file size but still be of the same quality. Creating WebM files will take longer time. 
The new filters for edit review tools and interface for watchlists will leave beta. This was supposed to already have happened but was delayed. For most wikis this will happen on 9 July. For the rest it will happen on 16 July. 
When you rolled back an edit it could get both the Rollback and Undo tags. This has been fixed. 
Rollbacks from autopatrolled users were not marked as patrolled. This has been fixed. 
Changes later this week
When you edit a link in the visual editor there will be two separate buttons to change which page the link goes to (target) or its text (label). 
On the mobile version you can find a link to an editor's contributions from their user page. Now this will work even if they haven't created a user page. 
When you edit a discussion on the mobile version you sometimes get your signature automatically added. This will now not happen if you have already added a signature manually. This is to avoid double signatures. 
When you look at Wikimedia code in Gerrit there will be a new interface. It is on by default for new users. This is also true for developers. This is to make it easier to understand what is happening. 
The new version of MediaWiki will be on test wikis and MediaWiki.org from 10 July. It will be on non-Wikipedia wikis and some Wikipedias from 11 July. It will be on all wikis from 12 July (calendar).
You can join the next meeting with the Editing team. During the meeting, you can tell developers which bugs you think are the most important. The meeting will be on 10 July at 18:30 (UTC). See how to join.
You can join the technical advice meeting on IRC. During the meeting, volunteer developers can ask for advice. The meeting will be on 11 July at 15:00 (UTC). See how to join.
The bot is remarkable, but it has this weakness of reverting back to a previous IP who was also a vandal. (Very small time gap between the two bad edits.) Personally, I check back as far as the last known-to-be sound named editor. Mostly it turns out that the changes were all vandalism, or else trivial differences. If the differences are good, then I come up to the point where a clearly deleterious change took place.
I'm inching towards an idea such as: "If the time gap between one IP and another is less than [say, one minute] revert back to last edit by a rollbacker" [or by a registered user].
There is another kind of edit rot which happens even when editors have the best intention. By changing one phrase an editor may affect a connection with another phrase later on. This latter is not relevant to bots, of course. It's to do with the gestalt effect whereby prose written by several is rarely as coherent as prose written by one (competent) writer.

The first problem is usually an indication of the bot mis-classifying the first edit as non-vandalism, and then classifying the subsequent edit (from another IP, usually within the same /24 block) correctly as vandalism. It is not about the bot getting "delayed" before the rollback; rollback requests identify the user to be rolled back, and would have been rejected by the API if it turns out that another user modified the page during the intervening period. I will look into adding more diffs to the bot's training database. Regarding edit rot, unfortunately the bot's primary role (and how the algorithm is configured) is to detect vandalism, not low quality content addition/modification; at this point I think the second issue is still something best left for humans to handle.

This user that you recently warned about his Roblox vandalism is continuing to post inappropriate content to many other pages. I believe he needs to be block ASAP before he expands his range. Thank you! --TDKR Chicago 101 (talk) 22:00, 15 July 2018 (UTC)
You can now see a new log of pages being created at Special:Log/create. It includes pages which are later deleted. It is now available on all Wikimedia wikis except Commons and Wikidata. 
You can see how many pageviews a wiki had from specific countries. The Wikistats2 maps have now been updated. 
Changes later this week
Your watchlist will show changes from the last seven days instead of three. If you have already set a length preference it will not change. 
The new version of MediaWiki will be on test wikis and MediaWiki.org from July 17. It will be on non-Wikipedia wikis and some Wikipedias from July 18. It will be on all wikis from July 19 (calendar).
You can join the next meeting with the Editing team. During the meeting, you can tell developers which bugs you think are the most important. The meeting will be on July 17 at 18:30 (UTC). See how to join.

Some articles have messages to readers about problems with the article. For example that it does not cite sources or might not be neutral. Readers do not see these messages on the mobile version. The developers now want to show them. You can read more and leave feedback.
You can use <inputbox> to create search boxes for specific pages. For example to search the archives of a community discussion page. Instead of prefix:Page name you will see a text that explains which pages are being searched. You can read more and leave feedback.
