Mandatory helmet laws have the consequence of reducing the amount of people cycling. There’s no justification for them when compared to international practices.

Many of those who support mandatory helmet laws do not understand what the purpose of a helmet is and that it will not protect you from a collision with a vehicle.

If you don’t want your kids accessing certain websites then the onus is on parents to control access. I do. If you want to do this structurally do it with ISPs and mobile carriers with router and SIM level filtering.

Put age limits on the ability to buy a device, SIM or internet package like we do for so many other things. It would be trivial to restrict access (and just as easy for smart kids to bypass as the current system).

Don’t use an iPad to babysit your child. Let them discover technology in an environment you’re confident and comfortable with. But it’s your job as a parent.

Or is all this really just about more mass surveillance under the guise of protecting the children?

I’ve used it to help students visualise topologies for meshing in command line CFD tools. It’s also great for motion tracking objects in video footage. I’ve even used it to simulate various camera systems.

Unfortunately the videos aren’t working on my iPhone. I’ll try on desktop later.

A recent local council attempt to remove a couple of parking spaces and install a shared space in the area I live was met with a wave of anger and vitriolic abuse. In a public consultation people were complaining about how it would prevent them bringing some elderly relative to the GP in the snow, while transporting a fridge. Meanwhile the area is permanently clogged with cars dodging a nearby toll making the place extremely unpleasant to use as an amenity.

It’s incredibly frustrating and saddening to contribute to the problems after trying so hard to do better.

About a year ago I started to take the bus. My commute went from an hour on the bike to over two hours. Spending four hours a day on a bus to travel such a short distance is not a fun experience. The bus meanders through a city choked with traffic. It's often faster if I get off and walk that part of the journey (I've checked). I enjoyed cycling for the most part. It was great for fitness and clearing my head. The parts of my commute away from cars were beautiful but there was a significant risk of death or serious injury every time I got on the bike. More and more drivers are buried in their phones. Cycle or bus and you'll see this.

The bus was slowly killing me. It was hard to work as the crowded bus wobbled around narrow Dublin streets along with various degrees of anti-social behaviour. I got off the bus angry and frustrated and groggy.

I've just bought a small little electric car and I can get to work in around 40 minutes. I don't have to listen to other people's loud voice calls or TikToks that are so loud they penetrate through ANC. I don't have to ask someone to make space on the seat they are occupying all by themselves and their bag and endure the dirty looks for it. I don't have to wait and wait for buses that never show up. I hate the bus. I hate that I hate the bus. I feel like a failure for having to buy a second car but I fucking tried!

I'm happy in my car. It's fun to drive and it makes me happy and guilty. I feel like I have so much more freedom. I'm not tied to the bus schedule which placed very tight limits on my time, and the bus frequently didn't show. Otherwise it would take much longer to get home. I can stop by somewhere on the way home and pick something up. Like the bike, I am by myself in the car and I can decompress. I can sing if I want.

It makes no sense for a 25km commute to take two hours. Its madness. By travelling from one suburb to another via the city centre the bus becomes wholly impractical. A public transport system has to work so that people leave their car at home. London worked for me, I got the tube everywhere. Valencia has an amazing public transport system. Dublin is completely broken.

The problem isn’t usually the narrow roads however, it’s the drivers everywhere who know there are no consequences for their behaviour.

Meanwhile we have endless PR events “pleading” and “urging” motorists to drive safely, many of which have photo ops with vehicles parked illegally on footpaths. All run by a Road Safety Authority government agency that is utterly incompetent and only seems interested in handing out high viz jackets to school kids and blaming them for being killed by motorists glued to their phones.

Which brings me to my pet hate, the utter contempt shown by Irish motorists for those around them, especially pedestrian and cyclist spaces. It’s extremely common for cars to be fully parked up on a footpath even if a parking space is in sight. I’ve had to dodge van drivers driving down the footpath on the Main Street of our capital city because they are too lazy to use the loading bay 50m down the street. This behaviour is accepted by almost everyone. Once a neighbour came around the corner with two wheels of her SUV on the footpath (presumably so she could mount the dipped kerb and park as close to her front door as possible). I had to jump back. I asked her, pleaded even, to not drive on the footpath. Apparently that was rude and she was highly offended.

Fuck cars.

You can create whatever start up file you want.

Other approaches include subsurface workflows, metaballs, signed distance functions, procedural (geometry nodes) and grease pencil.

When I made the point that there is no scientific novelty here they insisted that their PhD was a ‘generic’ one and that means they can continue to run basic simulations according the to the recipe.
