One of my Lego models got dropped today. I watched with a mix of horror and fascination as it shattered into a large number of pieces. As I was searching for the bits under the furniture I wondered whether taking videos of falling Lego was a thing. It turns out that it is, as you can see above.
This is a very nice little Raspberry PI case that makes it look like a Nintendo NES. It has a fan inside too. Not bad value from Pi Hut.
Very pleased with myself. I’ve taken on City Hall and won in a tumultuous 50 minute battle. Admittedly it was East Riding Council, and I was just trying to order something via their web site. But it felt like a battle.
And I did have to give them 10 pounds to sign up to get the service (and I’m not really sure why). So perhaps we’ll call it a draw.
Hull University was very good to me. It paid off my mortgage and helped me get my kids through college. Admittedly I was there a bit longer than I planned. Went for a three year degree course and ended up staying for another 35 years, finishing up as a lecturer in their wonderful Computer Science department.
I left a few years ago but I’m proud to be a fellow of the university and I’ve been able to watch them try to respond to this awful pandemic thingy. One thing I’m sure of is that all the staff will be moving mountains to make things work going forward and they’ll do it with the best interests of the students. Because they always did.
This is a Hull Computer Science speciality. Three Thing Game. If you fancy having fun writing games you form a team and you get given three things to base it on and a weekend to write it. I took this picture in 2013. Quite a few of the people in the shot are now out there making games of their own. You can find out more about it here. It’s hilarious whether or not you want to end up a game developer.
If are looking for place to study, don’t for get Hull. Lovely place. Lovely people. Find out more here.
I took this picture this afternoon. Who knew that butterflies were so hairy? If you want more detail you can click through the picture to the full sized image on Flickr.
We spent the evening playing Scythe. It’s a bit complicated for me. Every time I play it I learn one thing I should do and four things I shouldn’t . Anyhoo, I’ll settle for third place. Especially if I’m playing as Nordic.
Won a game of Disc Golf on the Oculus Quest this evening in Rec Room. Imagine my surprise when I search for details online and I find that frisbee golf is actually a thing. Anyhoo, I’ve found that the best way to throw it is to stand sideways and actually aim. Just like real life in fact. If you have a Quest it is great fun and very sociable.
What a man I am. I spent the morning writing and the afternoon demolishing a summerhouse. Who knows what I’ll do this evening…
Ages ago I went to a creative writing seminar. It was really interesting. One of the points that they made was that sometimes when writing you have to “kill your favourite child”. What they meant was that you might have a lovely chunk of prose that you are very proud of, but it just don’t quite fit into the context of the piece you are writing. There are two things you can do. Spend ages trying to make your wonderful words fit and fail. Or just get rid of them and move on.
I was reminded of this today when I was writing Chapter 9 of Begin to Code with JavaScript. I’m talking about software objects and I’d written a lovely piece of code that used a schema to create objects and properties on the fly. You can do this kind of thing in JavaScript and its awesome. However, I couldn’t make the example fit into the rest of the chapter. I spent far too long trying to create a solid context, wrote a few pages and then stood back from the piece, took a long hard look at it and then threw the whole thing away. What is left is much better, and of course I’ve not completely discarded the stuff. I never throw anything away.
Sometimes you have to ditch something that you really like because of your loyalty to the final result.
They were having a discussion on Radio Humberside this morning about the future of Hull. They asked me to contribute some thoughts. I made some notes (most of which I never used). So I thought I’d pop them on the blog. The question posed was something like: “As a person who has lived in Hull for a while, what do you think of the state of the city and potential for the future?”. These are my answers in bullet point form:
There are amazing things going on at the Fruit Market . I’ve been involved with c4di for ages and their building is now fully occupied with people making stuff and doing things. With more coming.
We’ve got super fast fibre networking, something which other places have just started to realise might be a good thing.
We also have a city wide LoRa network which is free for anyone to use for connected product development and a couple of local companies, KCOM and Connexin, who can provide you with a paid network service you can use to commercialise your solution.
Humber Street is awesome. The new pedestrian bridge will make a huge difference to access to the area.
We must give give local students a trajectory that encourages them to say in Hull when they graduate. As I said this morning, “It’s cheap and nice”, a killer combo. Students tend to be quite conservative about where they go in their local area. We need to encourage them to take a look at the lovely places we have where you could build a good life..
Hull Makerspace is a great development which lets anyone from the community explore technology.
It’s a crying shame that this nasty virus has come along just as we were getting up speed with all this, I really hope that progress is not knocked too far off beam by it.
I’m slowly getting my head around the Norns device that I built on my birthday. It works by running Lua scripts that talk to SuperCollider engines to make sounds. There’s also a sound sampler and sllcer and you interact with it via your browser. It’s great fun, but at the moment I’m using it to make the sound of rainfall thanks to the lovely Shower app. I’m trying to get my head around how such a short piece of code can produce something that sounds quite realistic. And very relaxing.
I’m writing Begin to Code with JavaScript at the moment and I was struck with how the choice of function names can be confusing. I’ve made the point that a good way to come up with a function name is to make them out of a verb and a noun. So storeItem sounds like a good name for a function. Store the item. What could be simpler?
Unfortunately this has the potential to be confusing. It’s because the word store can be a verb (do the storing) or a noun (a store that contains things). So storeItem might mean an item from the store. My strong advice is to try and pick unambiguous verbs, which is why I much prefer saveItem.
Perhaps I’m overthinking this (it has been known) but I’ve been surprised how many times I’ve picked confusing names for things based on distinctions like these. One of the great things about modern development is the ease with which you can rename identifiers, so if you do decide that the name you first came up with is confusing you can change it.
Do you want to learn JavaScript the fun and painless way? Then go forward 200 years into the future when they can plug something straight into your head. For now though, you could do worse than investigate the Begin to Code with JavaScript podcasts for my new book I’ve just uploaded. They are packed with jokes, music, song, dance and misleading product descriptions.
You can get a draft of the book for free and watch screencasts where I code things live that nearly always work. Search Apple Podcasts for “begin to code with JavaScript” or listen fresh from the web at https://www.robmiles.com/jspodcast
Blimey. That was something of a storm last night. I was watching the progress on the amazing LightningMaps.org and wondering how close to our house the dots would get…..
For every year that you are an MVP they send you a little glass disk that you can fit on a glass tower. I got my latest glass disk today. Very pleased. Thanks so much Microsoft.
I was digitally leafing through the latest copy of MagPi magazine when I had a sense of déjà-vu. They’ve included my HackSpace magazine article about creating Low Power clock controlled Raspberry Pi.
Quite chuffed. I’ve always fancied being in that magazine and now I am. Without even trying.
Authors note: I hope you are all really impressed by me typing “ déjà-vu” correctly. It was surprisingly hard to do.
If computers, big data, artificial intelligence and self-driving cars confuse you, you should read Hello World by Hannah Fry. Hannah is a proper scientist with a wonderful writing style and she makes the technology easy to understand. She also isn’t afraid to muse on the dark side of all this shiny stuff.
There is no assumed computer knowledge, everything is clearly explained and put into context and subjects are introduced with engaging real-life stories. Everything is also properly referenced so that you can follow up on things that you find especially interesting. Excellent stuff.
I’m loving my Teenage Engineering OP-Z. Great fun. One of the things I like about it is its versatility. The usb port can be used to make it into a usb MIDI host (so that you can hang other devices off it) or a usb MIDI client (so that it can hang off other hosts) or a sound output (so it can sample sounds sent over USB) or a sound source (so that other devices can grab digital copies of the sounds the OP-Z produces).
The only problem has been that I can’t get the last option to work on my Windows 10 PC. If I want to record stuff I’ve created on the OP-Z I’ve had to send out of the OP-Z headphone socket and then re-digitise it. Which seems a bit silly for a digital device.
Anyhoo, today I was able to try the OP-Z on a non-Windows device and discovered that it worked perfectly. Knowing that something is possible is very useful if you are trying to make it happen, and so I put a bit more effort into making it work. And I managed to do it. Here’s how, if you are having the same problem:
After you’ve plugged in the OP-Z, open up Device Manager on your Windows 10 PC by right clicking the Windows icon in the bottom left of your screen and selecting “Device Manager” from the menu that appears. Then open up the Sound, video and game controllers item. You can see that the OP-Z is a speaker (so we can send it sound) but not a microphone (so we can’t listen to it). Wah.
No matter. We’ve got this. Type “Control Panel” in the search box on the task bar and hit enter to open the Windows 10 Control Panel.
Now type “Troubleshooting” into the search window at the top right of the Control Panel and select the troubleshooting icon from the list that appears.
Now click Troubleshoot Audio Recording in the middle of the page.
Now click Next.
Select “Synthesizer - OPZ from the menu that appears and click Next again.
Windows 10 will do something magical that it should have done first time. Close the Troubleshooter and the Control Panel. Go back to your Device Manager and you should now see another input.
You now have another input device that you can connect to Audacity or whatever you fancy.
