In my professional life on the web, I tend to visit lots of the same URLs frequently. While I have (most of) them bookmarked in my browser, I usually don’t navigate to the bookmark and click it.

I start typing in the URL field of my browser (Firefox) and since autosuggest also searches the bookmarks, those are often visible. I realized though that this is still often too slow and not straight forward enough: It happens that many URLs are very similar and have the same first part, such as on Github many repos are under the same organization.

So a while ago I started using Alfred’s snippets to expand URLs for me. By using / as a suffix¹, this allows for speedy expansion of URLs I visit frequently. A bonus is that the same expansion works in other places where I need the URL, e.g. for linking it in blog posts.

So, for example, I have the snippet g/a/ to expand to https://github.com/akirk/. If I then continue typing fr, my browser can autocomplete much more precisely because I have already entered part of the URL to https://github.com/akirk/friends which I often visit.

Hope this can serve as an inspiration!

With the new Completions function calling API you can actually enable ChatGPT to access the internet. I did a few quick experiments where I provided it with a function called get_extracted_url_contents. See how it made use of it:

Matrix is an open-source internet-based chat system that operates on a federated model similar to email. It allows users to send and receive messages through homeservers, which maintain up-to-date copies of chat rooms. Matrix rooms can be either unencrypted and openly discoverable or end-to-end encrypted and invite-only, with encryption keys shared between users’ client software. There is a wide selection of Matrix clients available for different platforms, and a WordPress plugin called Chatrix has been developed to embed Matrix into WordPress posts or pages.

Research

This has been just a quick exploration following OpenAI’s announcement. Curious how we’ll leverage this better in future!

For my personal use, I created a CLI ChatGPT client a few months ago. It has been very useful for me to have it available in the CLI quickly whenever I needed it (caveat, you need an API key!).

Unfortunately, for larger responses it can feel very slow, whereas the web version feels quite fast. But this is perceived speed because it shows you each word as it arrives and not just the whole response when finished (after all it is a completion AI that generates the response word by word).

So now, I have added streaming support to it. It now feels almost too fast :) The CLI has a few nice things such as readline support (i.e. you can go back to old queries with the up key) and it keeps all of your conversation in a text file. All of this in only 100 lines of PHP.

I gave a talk at WordCamp Vienna 2023 about WordPress and the Fediverse. Find the presentation here:

I am working on bringing Matrix to the WordPress community (see also the WP Tavern post) and part of this is also to explain what Matrix actually is, so I wrote up a few paragraphs that I’d like to share here:

Matrix is an internet-based chat system like Slack or Microsoft Teams with a few key differences:

Open Source

It is open source (Apache License 2.0). Thus it includes the four freedoms (run it for any purpose, modify it, distribute it or a modified version).

Federated

There is no centrally controlled server, similar to e-mail (or ActivityPub): to send and receive e-mail, you need to have an account on a mail server. In Matrix, these servers are called homeservers.

When you send messages, these messages are first sent from your client (computer or phone) to the server, from the server to the recipients’ servers (in e-mail, you manually list them, in Matrix, these are all other people in the room), and then the messages are delivered to the individual participant’s clients. The benefit of this is that the client (like a mobile phone app) doesn’t need to be connected when the server receives the message and can catch up when it comes back online. 

For this reason, Matrix account addresses look similar to e-mail (or Mastodon) addresses but they have the format @username:server.tld. Starting when a member of a homeserver joins a room, their homeserver will maintain a full, up-to-date copy of the chat room. Any message sent by others in the room will be sent to every participating homeserver. For this reason, joining a room can take a while because the server needs to (partially) populate its local copy from other homeservers. Because of the real-time nature of chat, the messages are exchanged very quickly between the homeservers as soon as that connection has been established.

A Matrix server can also be run in unfederated mode where it will not communicate with other servers on the internet, thus enabling a closed community. This decision can also be made on a room-by-room basis.

Encryption

Matrix rooms can be either unencrypted and openly discoverable, or end-to-end encrypted and invite-only. Because the server has no knowledge of contents or encryption keys, the latter need to be shared between the individual client software of a user. This is established through a verification step in which you use your other/old client to establish trust with the new one. Until this has happened, any encrypted communication is inaccessible.

Open Protocol

The Matrix protocol (and all of its updates, called MSC) is publicly available and can be implemented by any software. There are a couple of server implementations with best known ones by Element themselves, called Synapse (Python based) and Dendrite (Go based). Clients are easier to implement through Matrix provided SDKs that do the heavy lifting of encryption and protocol communication.

Free Choice of Clients

For the above reason, there is a wide selection of clients for mobile and desktop, different operating systems, text based, etc. We have developed a WordPress plugin called Chatrix that allows embedding Matrix inside a WordPress post or page which allows something like we demonstrated in this GIF:

Loving this alias (requires brew install gh):

pr() {
        git fetch
        gh pr checkout $*
}

It will switch to the right git branch based on the PR number like this: pr 45 will switch to the branch of pull request 45 of that github repo

One thing that I like very much about my family is the anecdotes and stories. One thing that I am bad at, is reciting them.

So I had this idea to create something like a private Wikipedia for my family, where each person has their own page and family members can contribute to the stories, biographical data, and media.

Initially, I set up a MediaWiki, i.e. the same software that Wikipedia uses. It turns out, it’s not that easy to configure. The new Wiki editor is much better than directly editing wiki syntax but the complexity is high for a small project like that. Also, uploading media is quite a pain because of the importance of licensing metadata. In a private wiki, you’ll want the UI to get out of the way.

So, since I work with WordPress a lot, I had the idea to use WordPress for it. There are a number of wiki plugins for WordPress but they all seemed overly complex and not really geared towards a use case of users collaborating on creating a site.

Thus, I created my own WordPress plugin called Family Wiki, available for now at https://github.com/akirk/family-wiki/

WordPress has the advantage that you can set it up very quickly and got many options for setting it up. Plus, when you have already multiple blogs (e.g. for family members) on your domain, it’s easy to just add another blog to your WordPress multisite. The plugin works on a standalone blog, too.

Here are some screenshots that I made as a demo:

Recently I wanted to use a Jetpack block for the WordPress Gutenberg editor, specifically the Slideshow Block, which I think is very slim and elegant compared to other Slideshow blocks on the WordPress.org plugin directory.

The one thing I didn’t want to do, though, is to connect my site to WordPress.com. For the most part because I didn’t intend to use any of the functionality that requires the WordPress.com connection.

The difficulty in this: normally, you can’t actually use Jetpack until you connect the site to your WordPress.com account. This behavior is in place so you can enjoy a friction-less experience after the connection is established (i.e. you can activate any of its features whether or not it needs the connection).

In my case, the connection is not needed for using the Slideshow block since it works with the local media library.

So, I present not a hack but an official way to use Jetpack without a WordPress.com connection: it’s called Offline Mode.

You activate it by adding a constant or filter to your wp-config.php, for example:

define( 'JETPACK_DEV_DEBUG', true );

While it is intended for local installs and actually development, it is useful if you just want to use a single feature of Jetpack that doesn’t require the connection.

Many people say that Jetpack is slow because it’s so big. It is indeed huge from a file size and feature perspective, but also it’s very optimized, so that it will only load the PHP or JS code it needs. The other files lay dormant in your file system and don’t contribute to the loading or rendering time of your site.
