David is semi-retired from Wikipedia due to both personal reasons and way too much wikistress. I only log in and edit occasionally. I do check my messages here from time to time, but don't expect any answers or work from me.

Your account has been granted the "templateeditor" user permission, allowing you to edit templates and modules that have been protected with template protection. It also allows you to bypass the title blacklist, giving you the ability to create and edit editnotices. Before you use this user right, please read Wikipedia:Template editor and make sure you understand its contents. In particular, you should read the section on wise template editing and the criteria for revocation.

You can use this user right to perform maintenance, answer edit requests, and make any other simple and generally uncontroversial edits to templates, modules, and edinotices. You can also use it to enact more complex or controversial edits, after those edits are first made to a test sandbox, and their technical reliability as well as their consensus among other informed editors has been established. If you are willing to process edit requests on templates and modules, keep in mind that you are taking responsibility to ensure the edits have consensus and are technically sound.

This user right gives you access to some of Wikipedia's most important templates and modules; it is critical that you edit them wisely and that you only make edits that are backed up by consensus. It is also very important that no one else be allowed to access your account, so you should consider taking a few moments to secure your password.

If you do not want this user right, you may ask any administrator to remove it for you at any time.

If you were granted the permission on a temporary basis you will need to re-apply for the permission a few days before it expires including in your request a permalink to the discussion where it was granted and a ((ping)) for the administrator who granted the permission. You can find the permalink in your rights log.

I must say it is an amazing way to detect IPv4 users without Lua. But things have changed these years and do we need a Lua module to make the implement less hackish and add IPv6 support as well? (I'm not so familiar with English Wikipedia and did not find a wheel to do so) Thanks, WhitePhosphorus (talk) 04:54, 25 December 2019 (UTC)Reply[reply]

 Done - I took a look at it. I went ahead and updated ((IP-user other)) so that it now detects IPv6 user pages too. Didn't need Lua for that. The IPv6 detection part is actually cleaner code than the IPv4 detection, since it was simpler to detect IPv6 user page names. Note that the template now uses a ((IP-user other/core)) subtemplate, in case you are copying it to another wiki.

And thanks for pointing out the need for IPv6 detection. I looked around and noticed that some of our system messages such as MediaWiki:Anontalkpagetext only shows on IPv4 user pages. So now that I have updated the ((IP-user other)) template we can use that one to fix all that.

Welcome back, David! Is this just scratching an itch, or do you think it's likely to be longer-term? 「ディノ奴千？！」^{☎ Dinoguy1000} 17:03, 31 December 2019 (UTC)Reply[reply]

@Dinoguy1000: Thanks! And well, only time will tell. But I won't be back full time, my other project is more important to me. But I might go back to periodic template editing. Right now I am updating/modernising some of my old stuff here. Like templates, MediaWiki messages, image descriptions for images I uploaded and so on. And answering (old) questions on the talk pages of templates and articles I used to work with.

--David Göthberg (talk) 21:55, 31 December 2019 (UTC)Reply[reply]

Aah, I can relate; I've pretty well moved on to other things myself, as well. If you don't mind me asking, what's your other project? 「ディノ奴千？！」^{☎ Dinoguy1000} 22:55, 31 December 2019 (UTC)Reply[reply]

I am a software engineer specialising in computer communication. Since 1997, and full time since 2000 I have been researching and teaching algorithms for totally serverless peer-to-peer networks with billions of nodes. Or in plain english: How to make billions of home computers cooperate without any servers. (Mostly on top of the existing Internet, but also in radio based ad-hoc networks = wireless mesh networks.) For instance, since 2006 we have all the stuff needed to build a Wikipedia without any servers at all. Just an application that the users install locally on their computer, and then all those applications cooperate to make a global Wikipedia. And yes, it could still have editing, version handling, edit filters, bans, different user rights like admins, and so on. People could of course also set up "servers" so users without the application could read and edit. But if/when those "servers" went down, those with the application wouldn't even notice and just go on reading and editing as usual.

I tend to edit Wikipedia for some months when I need a break from all that. Sometimes I get stuck here longer... :)

--David Göthberg (talk) 00:25, 1 January 2020 (UTC)Reply[reply]

Ooh, that's some really cool stuff! Though I think a lot of it goes over my head. It certainly beats the pants off of anything I do... =)

Generally nothing I do here these days is nearly as involved as it used to be, but don't hesitate to ping me if you think I can contribute usefully on something you're looking at (though I also really doubt I have much to say on anything that you wouldn't have already considered). =) 「ディノ奴千？！」^{☎ Dinoguy1000} 05:50, 1 January 2020 (UTC)Reply[reply]

Haha, thanks. Yeah, it has been the trickiest research in my life.

And thanks for the offer of help here at Wikipedia. I am out of practise so I might need it. For instance, today I resorted to ask for advice over at the Village pump (technical). It was nice to see that the Village pump still is a fast and nice way to get advice.

Doesn't Wiki mark unsigned messages using the poster's username? — Preceding unsigned comment added by DuncanMacC (talk • contribs) 00:46, 5 February 2020 (UTC)Reply[reply]

@DuncanMacC: Well, both yes and no. The wiki software itself does not sign your messages. A talkpage is just another "edit-any-way-you-want" wiki page. But we have a bot (SineBot) that goes around checking edits and adding the kind of slightly ugly signatures as you now see on your message here. And sometimes when we edit a message in an unusual way the bot doesn't even understand how to sign it. So it is better to use the "signature and timestamp" button at the top of the edit window to get a nicer looking signature, and get it immediately. As I did in this message. That button adds --~~~~ when you press it, which is the wiki code for a signature. A common practice among "old" editors is that when we do forget to sign and we then later see that the bot has signed for us, then we edit the message again and instead add the normal nicer signature.

Also another thing we do (as I did in this answer) is that we usually indent our messages using the ":" wikicode. And we add more of those ":" for each message. But the first message in the section we don't indent. So open the edit window and take a look at the code for this section.

And another thing we sometimes do is the ((ping|username)) that you can see I did at the start of my message which causes the system to give you a notification that someone mentioned your username in the text.

What is your position on hashlists.com?? 43.231.28.179 (talk) 20:45, 3 July 2022 (UTC)Reply[reply]

Do you think you can hide from world?

After scamming 1000s of people you can't hide from us. Soon will track you down. Where is your brother 43.231.28.179 (talk) 20:47, 3 July 2022 (UTC)Reply[reply]

I have no affiliation with hashlists.com, and this is probably the first time ever I hear about them. I did a quick search and it seems that hashlists.com is about crypto mining, and that people say it is a scam.

I think you found my name for one of the following reasons:

• I wrote the article Hash list here on Wikipedia and made the hash list diagram for it. That article is not about cryptocurrency or crypto mining. Instead it is about a method we use in peer-to-peer applications such as Bittorrent. I have also edited several related pages about p2p technology here at Wikipedia.
• I am a scientist researching peer-to-peer technology (p2p). See the message Back?! above for a longer explanation what that means. That means my name often pops up on web sites about p2p stuff. Since crypto currency is a related technology sometimes people also mention my research and my name on web sites about crypto currency. I have also talked at conferences that had two topics: P2p technology, and crypto currency.
• At the conferences I often get the question what I think about crypto currency. I answer that it sucks for a bunch of reasons (both technical and human reasons). I don't like crypto currency. When they ask what improvements I might suggest I explain one of my solutions that I think would work better. One of the current big developments in crypto currency uses the same idea and they started developing it some years after I had suggested that solution at several conferences. So it might be based on my ideas and thus they might be mentioning my name in their forums and documentation. But it might also just be a case of engineers coming to the same conclusions when they see the same problem. I haven't gotten around to ask those developers where they got the idea from.
• I made a bunch of diagrams about cryptography and about hashing that we use here at Wikipedia. My diagrams about public-key cryptography have become very widespread: They are used at some universities when teaching crypto, they have been printed in books about cryptography and about crypto currency, and it wouldn't surprise me if you would see my diagrams in crypto currency web sites / documentation since crypto currency also uses such public-key cryptography. Often people correctly put my name next to the pictures.

So you see, you must have stumbled on my name by accident.
