Computer Education in Schools Instruction Language (CESIL)

When I first learned programming in about 1978 the school I attended was lucky to have a Research Machines 380Z on which there was the BASIC language. Using this one of the pupils then wrote a CESIL interpreter for their (I guess) O Level project. Other pupils then used this to learn the fundamentals of programming.

Skip forward a few years and I now owned a Sinclair ZX Spectrum having also previously had a ZX81 too. I decided that I would also write a CESIL interpreter this time using Sinclair’s variant of BASIC. Remarkably I still own the sheets of … Read the rest

Overcast Statistics

Podcasts are huge at the moment and they are pretty much all I listen to these days when I am out walking or in the car. I do this by the (mainly) excellent Overcast app. I say mainly because it has a UI that I struggle to find things in. Anywho, the one thing that it lacks (other than an intuitive UI) are decent stats and I really wanted that for my annual Review of the Year posts over on my personal blog.

After a quick DuckDuckGo I found the following post from James Hodgkinson with a Python … Read the rest

An Open Letter to Google

Dear Google,

In 2014, around about the same time that you Nest Labs, I bought and had installed a Nest Learning Thermostat to control our central heating and give us remote access. I think that it has been a great success, so much so that I have recently upgraded to the latest version that also allows our hot water to be controlled.

I then had an idea! What if I could see temperatures around the house and use that data to get better control over resources there? So I wrote a simple dashboard which I called The Weather Station. I’ve … Read the rest

Cloudflare Zero Trust

I love Cloudflare – there I have said it! If you are looking for a way to keep your site secure and performant then Cloudflare is the way to go. Today I am going to be looking at just one aspect of Cloudflare and what it can do for you – Zero Trust.

What is Cloudflare?

I like to think of Cloudflare as the Swiss Army knife of cloud-based tools. It offers solutions for a variety of things from security to performance to domain registration to content delivery all packaged in an easy to understand and use web-based interface. And, … Read the rest

ChatGPT as a Replacement Programmer

When I left university I did so with a good grounding in several programming languages such as Cobol, Fortran and Pascal. Then, at my first job, I was given training in the language Application Master, part of ICL’s VME operating system. One of the things I was told about Application Master was that it was a “fourth generation language (4GL)” and that this would be the last generation that required a developer to write the code.

This was the late eighties and until very recently we have been still waiting for this transition to happen.

ChatGPT has Entered

Using a Raspberry Pi Camera to create a time-lapsed video

For my birthday last year I was bought a Raspberry Pi Camera Module 3 which I’d wanted for a while. I’d decided that I wanted to create a time-lapse video showing the change in seasons in the back garden. The rest of this article describes what I did and the results.

Setting up

As this didn’t require a huge amount of computing power I paired the camera module with a Raspberry Pi Zero 2W.

That turned out to be the easy bit! Getting it fixed such that there weren’t any reflections from the window took a bit of creativity. What … Read the rest

Changing your Bluesky handle to be your own domain

I’m liking Bluesky, which is a little like a rough around the edges X without the toxicity found there. And here’s a neat thing you can do on Bluesky that you can’t on X. If you have your own domain you can use that as your Bluesky handle. In the rest of this article, we’re going to look at how you do that.

Why would you want to do it?

First off why would you want to do so and what are the implications of making the change? I see a number of reasons to make the change:

Posting to Bluesky via the API from PHP – Part Five – Putting it all Together

NOTE: This post is mainly about how I developed the php2Bluesky library. If you are looking for information on using the library in your own code please see here: https://github.com/williamsdb/php2Bluesky/

In this series of posts we have looked at:

In this final post we are looking at putting it all together. This includes a worked example plus a complete library of functions that will allow you to easily interact with the Bluesky API.

Posting to Bluesky via the API from PHP – Part Four – Link Cards

NOTE: This post is mainly about how I developed the php2Bluesky library. If you are looking for information on using the library in your own code please see here: https://github.com/williamsdb/php2Bluesky/

In this we post we are continuing to look at accessing Bluesky from the API via PHP. Previously we looked at making a connection to Bluesky, posting text, images and handling links and in this post we take a look at Link Cards.

What Even IS a Link Card?

Link Cards are the snippets of a website that is linked to a post that you will no doubt be … Read the rest

Posting to Bluesky via the API from PHP – Part Three – Links

NOTE: This post is mainly about how I developed the php2Bluesky library. If you are looking for information on using the library in your own code please see here: https://github.com/williamsdb/php2Bluesky/

So far we have looked at making a connection to Bluesky, posting text and images. In this post I want to look at how links are handled. Unlike X and Mastodon on Bluesky when you post text that includes one or more links these are not parsed and activated. You have to tell Bluesky that you have links in your text and where they are.

Parsing for Links
