Seven Years On Mastodon


Cartoon of a tusked mastodon holding a phone.

I remember seeing the original "A new decentralized microblogging platform" on HackerNews back in October 2016. A few weeks later, I joined - becoming the 7,112th user. As the years went on, my use of it waxed and waned. I started cross-posting to both Mastodon and Twitter. Gradually, I started spending more time on the […]

An open(ish) redirect on Mastodon


Cartoon of a tusked mastodon holding a phone.

I've responsibly disclosed a small security issue with Mastodon (GHSA-8982-p7pm-7mqw). It allows a sufficiently determined attacker to use any Mastodon instance to redirect unwary users to a malicious site. What do you think happens if you visit: https://mastodon.social/@PasswordReset/111285045683598517/admin? If you aren't logged in to that instance, it will redirect you to a 3rd party site. […]

How far did my post go on the Fediverse?


Cartoon of a tusked mastodon holding a phone.

I wrote a moderately popular post on Mastodon. Lots of people shared it. Is it possible to find out how many different ActivityPub servers it went to? Yes! As we all know, the Fediverse is one big chain mail. I don't mean that in a derogatory way. When I write a post, it appears on […]

Some thoughts on Mastodon search


Cartoon of a tusked mastodon holding a phone.

The latest version of Mastodon includes search functionality. It's early days, but seems to work pretty well. Here are some of the interesting things I found when using it. Search is complex - expectations I don't mean the act of searching a database - that's routine - but I mean it is socially complex. Lots […]

Fediverse Account Portability And Blocking


Cartoon of a tusked mastodon holding a phone.

One of the many great things about the Fediverse (Mastodon, PixelFed, Lemmy, etc) is that your account is portable. Let's say you're bob@social.boring and, one day, you decide to move your account to foxyfun@furryextreme.yif. Well, with a few clicks of a button, all of your old followers are now following your brand new account. You're […]

Federation is pretty cool, but kinda confusing, and maybe a little scary


Otome-chan says: "See here. you can see this mastodon user's post (which to them looks like a regular tweet on twitter does) ends up in our random microblogs section. We can also view their profile directly as well as follow them to have their posts appear in our microblogs (as well as threads if they go out of their way to make one). It seems kbin microblogs appear as threads/comments to you on lemmy. so I have to imagine mastodon posts might be similar?"

Last week, this strange mention appeared on my Mastodon feed. After a bit of clicking around, I figured out what had happened. A user on the Kbin social network had linked to my Mastodon profile. Thanks to the magic of the ActivityPub protocol, it filtered into my mentions - even though I've never even heard […]

How do you decentralise emergency alerts?


Cartoon of a tusked mastodon holding a phone.

Twitter's decision to hobble its API has meant that a number of useful alerting bots might no longer function. Your local subway might not be able to Tweet each morning about delays on the line, nor will a tornado warning be displayed as you scroll through photos of brunch, and forget about flood alerts between […]

Posting Untappd Checkins to Mastodon (and other services)


HTML source code of the page.

I'm a big fan of Untappd. It's a social drinking app which lets you check in to a beer and rate it. Look, we all need hobbies, mine is drinking cider. You can see a list of everything I've drunk over the 13 last years. Nearly 900 different pints! After checking in, the app automatically […]

Naming things is hard - DNS for the Federated Web


The multicoloured interlocking lines of the Fediverse logo.

How should I design my personal DNS for all the cool new Federated Services and IndieWeb protocols? Way back in the early 2000s, I started this website - shkspr.mobi. A few years later, I added a blog. I could have used the main domain, or created a subdomain like blog.shkspr.mobi. In the end, I chose […]
