The guy at Not Just Bikes will tell you that enforcement will never work nor happen and that the only way to get people to slow down is to design the road so it doesn't feel safe to drive fast. The road next to my house has a speed limit of 20mph but most cars go 45mph because it's a straight road 4 lanes but space for 6. No bumps, no curves, wide. Effectively it feels like you should be driving fast. If I go the spe…

Agree, but also disagree. Our neighboring town has a beautiful system in place. It tracks your average speed over +- 100m. If you speeded, you get a fine and even better: the light always turns red and you have to wait for a minute. If you run that red light, you get another (heftier) fine. If you drive normally, the light is always green. It's beautiful. People actually drive slowly and safely there. And good, becau…

I have never seen a system like that. What town? Or what system?

I'm building an interactive, web-based Python tutorial site intended to help with learning basic syntax. Originally it was for my kids who wanted to learn to code, but... might be useful to others. https://learnpy.dev The content needs some work, but I'm pretty happy with the framework / UX. I would love to get any feedback from folks who check it out! (The first section is just multi-guess questions as part of the i…

the navigation buttons should be at the bottom, because that's where you are when you finish a question. or maybe a "next" button that only shows up when a question is answered correctly.

content wise, i found the first lesson to dry. i'd rather start with something interactive, and explain necessary concepts along the way. the print lesson introduces the separator feature which is rather rarely used and should only be introduced when there is a practical need for it.

You are not allowed to put up unlicensed surveillance cameras in public places, no.

What is a licensed security camera? By this logic, are you saying cameras on private property, that happen to capture public space in their frame are also illegal?

Of course it is. Is this controversial anywhere? I would expect surveillance cameras to be regulated in most parts of the world, certainly around Europe. In the Netherlands I believe you need to register such cameras with the local police and you are responsible for following the relevant regulations and data protection laws.

Wow, this is really cool. Do you take inspiration from or have you looked at the original Wolfenstein3D code? https://github.com/id-Software/wolf3d

Thanks I appreciate that! Love getting feedback :) Code-wise I didn't take inspiration from anywhere, I followed "C Programming - A Modern Approach" and based my C knowledge off there. There was also a YouTube video I watched regarding raycasting, and watching people optimise Minecraft etc. Other than that, its just been alot of trial and error and trying many, many different ideas out. What has helped is I don't wor…

Also I’m a terrible developer, so if I can do it and have a lot of fun, I think anyone can do it :)

I spent almost 8hours a day over the course of a month working on and off on the project.

Did give me tunnel vision but, no regrets

I walked away from tech and bought a farm. So:

I've built a large solar array on a repurposed mobile home chassis and have been digging a trench through rocky ground to lay the conduit for the cabling to backhaul the DC power to the shed where the inverter and battery bank will live. It's the rainy season in Ireland, and that field was marginal at best, so it's been swampy work and half of the digging is trenching additional drainage channels so the conduit doesn't flood and path water back into the shed. There's a housing order due to a bird flu scare, so I'm not running poultry on pasture until it's lifted (or until I can get the government to agree that my pasturing system qualifies as housing). Annoying, but that's farm life.

Oh, I'm doing some shit with AI also, but that's a secret :)

I've recently been prototyping a mobile application to track your food nutrition. The key feature lies in auto-detecting the food based on a given image, and breaking it down into it's ingredients and then into it's macros. Existing apps such as MyFitnessPal and HealthifyMe fall into two ends of the spectrum where you either need to add ingredients one by one, or your food is logged with a standard macro count where…

I invested in http://usenourish.com (a YC company) that recently launched this. If you want to work on this for them, happy to intro.

I'm building a new tool for end-to-end data validation and reconciliation in ELT pipelines, especially for teams replicating data from relational databases (Postgres, MySQL, SQL Server, Oracle) to data warehouses or data lakes. Most existing solutions only validate at the destination (dbt tests, Great Expectations), rely on aggregate comparisons (row counts, checksums), or generate too much noise (alert fatigue from…

This sounds interesting. Is this meant to run in pipelines or be used interactively? Are you building something open source? Link to the repo?

It’s meant to run in or alongside the pipeline continuously.

Not planning to open source, working on a commercial offering but haven’t launched anything publicly yet.

Would love to hear any more thoughts on the concepts here or my email is in bio

Just went through the company's website, and I like how well the software ties into the company's motive/direction.

I'd appreciate an intro, thanks! I could send an email, or you can find mine on my bio :D
