My PC at home does actually host a website for testing purpose which you may be interested in seeing. A lot more content will be provided over time.

wlgfx@home Link updated (2017 Jul 31)

This only works when my home PC is on.

Hosting a website from your home PC is possible by using NOIP.com which my Sky router updates each time it is rebooted by sending noip.com my IP address. From there I added a setting on my router which redirects a port to a static IP which my PC is set at.

And that folks, is how I host stuff from my PC.

I only use Apache Tomcat 7, I’m not interested in PHP or SQL.

I’ve also tested out opening a specific port on the router and redirecting to my PC and having a TCP listener. The listener will accept 4 bytes (a command code). If the 4 bytes do not match any valid commands, the connection is closed. Otherwise it will send data back to the client. This project was an interesting test and is not currently running as I do not want to leave open ports on the internet for too long.

And out goes 2024… (almost there…)

Hello everyone,

For a long time I've been bouncing between projects and not sticking with one. Probably all down to what life throws at you.

So lately, I've moved from Godot to using Raylib. Godot as an engine is amazing for not only beginners, but for advanced users too with its native development cycle. Raylib however, being a very cut down framework opens up a lot of options. You can find my latest project here.

My development platform:

OS: EndeavourOS + Wayland + KDE
PC: Higole F9B 512Gb model with 16Gb RAM. Intel N100.
Software: VSCode, OpenMPT(Audio), Blender(3D), Inkscape(Vector), Krita(Artwork)

The main reason for choosing Raylib over Godot is simply that I have raw access to what is being rendered. Raylib is a C framework and I am building my own framework in C++ over the top of it.

An example of the simplification can be seen in the source code.

These last 2 weeks have mainly been getting used to the API itself and its data structures. And now I am moving over to using shaders for the first time manually.

Although saying that Raylib is cut down. It still has everything I need right now without all the extra bloat. And once I've gone through the API and C++'ified it, building applications should be much easier.

2025 should be a creative year for me... See you there...

Godot 4 Terrain Generator – progress

July 27, 2024

I’ve just uploading another video to youtube about the current progress of my work on 3d terrain generation.

Here I am mixing two noise values, a main noise for the actual terrain and the other which is only added at 10% strength adds extra terrain detail patches.

There’s still a lot of ideas yet I want to add to this and I am getting through them bit by bit.

Audio issues are still ongoing and hopefully will be resolved in future videos.

Until next time… Carl out…

Godot 3D terrain testing

Just using GDScripts SurfaceTool, here’s a quick glimpse of what I’ve been fiddling around with.

For some strange reason Godot keeps calling me back, and each time I play with something else. This is the latest.

Think of now using a threaded solution to generate meshes using 3D noise and maybe even stretch it a little and animate it with 4D noise as a constant time dimension added.

I dunno…

I was thinking just then, “hey, you do know that adding 6Tb storage to your PC is a big deal?” Well, that’s when it struck me, actually, yes it is!

They’ve been sat in the NAS case for almost a year now since I cut Windows on all my PC’s at home. And I never got round to setting it up for Linux. It kinda got that way, I had a 2Tb SSD to shove all my stuff on.

So a week later and Aliexpress delivers my HD caddies. Straight away, unboxed, 2 x 3Tb drives straight into them, and all setup. And voila! They all work and now I’m sat here with a tiny Mini PC, with about 10.5Tb of storage in total connected to it.

So, yeah… It’s a big deal.

… Now on to organising it all. (That’s the bummer…)

Z80 Spectrum 48K assembler

So I finally got around to making my very first recording with my voice over to quickly demonstrate how easy it is to edit and run assembler code on a ZX Spectrum emulator.

Click here to view the video on Youtube.

ZX Spectrum 48k (adventure)

I’m hoping to record a video showing where I’m up to with my trip down memory lane.

Portable monitors are awesome! … ?

Straight up, yes they are. I have two, an 11 inch standard HD and a 15 inch 4K. Both power over USB, both have extra USB C ports on them and both have USB C video input and HDMI.

They are also thin, very light and come with a magnetic cover which acts as a stand. The brightness and colours are perfect to me.

But, …

When it comes to the resolution and the size of the monitor itself, especially the 4K monitor, ‘size matters’.

I do a lot of programming and screen real estate is essential for displaying code. The more code you can see on the screen, the better. And here’s were the 4K monitor falters.

At that resolution, you know 4 times the space of a HD screen. Well, in resolution anyway. You’d think, or at least I did, silly me. You’d think that opening 4 browser windows in each corner or the monitor. Oh yeah, that is cool.

Nope. It’s a 15 inch screen. Splitting it up into 4, 7 inch screens doesn’t work. Simple as. You strain your eyes reading tiny, tiny text.

For programming they are superb. But to split the screen up smaller, nope.

Oh, I’ve also got a 28 inch 4k monitor and I can confirm it doesn’t look too bad splitting 4 browser windows.

Microsoft and Chrome

I’ve not long got a new PC and my first Windows 11. As usual, I set it up the way I like it.

Then, I boot up to find Edge has opened all my Chrome tabs.

The weeks go by and I see reports of the same thing on YouTube.

And now today, I’m getting emails from Microsoft asking me to recover my Google account through them.

Hmm

2024 Updates

So it is time for me to setup a new development folder. This time around, unlike the many years in the past, all the test projects will be dumped into a testing folder before they are allowed to join any main stream projects that I am working on.

Now with a PC upgrade I am capable of working a lot faster (8 cores/16 threads helps here), especially with running local AI’s and also working in Linux and MacOS. Most of this will be all on the same machine.

Current projects:

Media server and device management software/server.
- Video playback
- Image viewer
- Devices manual updates by client
- plus many other features…
Godot Game
- Terrain generator and texture painting
- Fauna splatting
- Various generators to add objects in a scene
- Miscellaneous player controls (ie. sliding down slopes and climbing walls)
Home AI chat on the go.
- Home AI that runs on a server that allows me to chat over the internet using my phone
- Text or speech input.
- Optional text to speech output
- Selection of local LLM’s (ie Llama chat, or Mistral Instruct)

With WSL in windows it does make it easier to develop and test Linux software, however it is not that good because it doesn’t give raw access to hardware. This is not a problem for development and testing.

There will be a lot more to come over the months as things start to get organised and time is given to these projects.

Catch you all soon…

Testing before an interview

It’s extremely important if you are taking a laptop to an interview to showcase a project that you’ve been working on to thoroughly test it before going. I found this out recently.

It was a Node JS project I had been working on for about six months, it loaded up, built and ran fine the night before and even on the morning of the interview. Doubts that anything could go wrong just didn’t exist. This project was working.

But that wasn’t the case in the end.

During the interview I booted up, loaded the project in as I had been doing, no changes to the system or project. Then I ran the project and opened up the page in a web browser.

Garbage! That’s what I got on the screen. Just garbage!

According to the output log from the project it was all going fine, but that’s not what was on the screen in the browser. I could see some of the text and icons but they were all squashed up on the screen. Argh! I thought. How could this happen?

I had to resort to just explaining the project and apologising for the failure for it to work properly.

Interview over and headed back home on the train. Furious at myself for this to happen.

Whilst on the train, I opened up my laptop to write a thank you email for the interview which I had to connect to my phones hot spot. Email sent, I decided to open up the project to quickly see why it all went wrong. The project ran, I opened it up in the browser… And it just worked!

After a very short investigation I found what the problem was. A CSS file was being requested from a CDN (content delivery network) which when connected to the internet could get access to and use in the project. During the interview, I did not connect to the internet and the CSS file was not loaded into the page. No layout information, colours, nothing…

So that was it. No internet. Project cannot access that single CSS file.

Of course now I’ve added the CSS file directly to the project and it does work completely offline.

Lesson learned.
