That's the "Idaho stop". You're moving at speeds slow enough to be easily able to check for traffic without stopping, plus losing inertia as a cyclist is much more annoying (and arguably even dangerous) than for a car.

From a driver's perspective, you don't want to wait an extra 5-10 seconds because now the bike in front of you has to get back up to speed. 0-5mph is the slowest change and the most energy

I live in one of the areas they are actively testing/training in. Their cars consistently behave better and more safely than most human drivers that I’m forced to share the road with.

As semi-autonomous and autonomous cars become the norm, I would adore to see obtaining a drivers license ratchet up in difficulty in order to remove dangerous human drivers from the road.

The real issue is all the current bad drivers. A requirement to start re-testing normal people in addition to the elderly would be a large benefit to society.

Oliver is doing awesome work here. A few interesting points:

- Porffor can use typescript types to significantly improve the compilation. It's in many ways more exciting as a TS compiler.

- There's no GC yet, and likely will be a while before it gets any. But you can get very far with no GC, particularly if you are doing something like serving web requests. You can fork a process per request and throw it away each time reclaiming all memory, or have a very simple arena allocator that works at the request level. It would be incredibly performant and not have the overhead of a full GC implementation.

- many of the restrictions that people associate with JS are due to VMs being designed to run untrusted code. If you compile your trusted TS/JS to native you can do many new things, such as use traditional threads, fork, and have proper low level memory access. Separating the concept of TS/JS from the runtime is long overdue.

- using WASM as the IR (intermediate representation) is inspired. It is unlikely that many people would run something compiled with Porffor in a WASM runtime, but the portability it brings is very compelling.

This experiment from Oliver doesn't show that Porffor is ready for production, but it does validate that he is on the right track, and that the ideas he is exploring are correct. That's the imports take away. Give it 12 months and exciting things will be happing.

Based on how much imported libraries are relied upon, it makes sense to treat everything as untrusted. Unless you write every line yourself/in-house, code should be considered untrusted.

I would be curious which attack vectors change or become safe after compiling though.

It's really easy to avoid your employees being "poached": treat them well, and pay them better.
gibolt · 9 days ago
I generally agree, but the company likely doesn't have those funds. Considering the largest player (Apple) stands to make way more from it than you and just works around your patent.

Not arguing Apple shouldn't poach, just that your suggestion doesn't work.

Researchers discovered the black hole has been consuming AI VC money, at the rate of $50M per day, and so finally explaining why it is gotten so big.

If this story is true, this would appear to be a simple vector for hijacking email intended for other gmail users. Hard to understate the severity if true.

Have you tested whether you can receive email directed to firstlast@gmail.com? Perhaps theirs is really firstlastt@gmail.com and all their contacts "correct" it.

This feels like a bug that he snuck through early or during a temporary window, before Google started defaulting to . as an ignored alias. Maybe not ¯\_(ツ)_/¯
gibolt commented on Show HN: Goboscript, text-based programming language, compiles to Scratch   github.com/aspizu/goboscr... · Posted by u/aspizu

I love teaching Scratch to kids. Some years ago, I used to do "CoderDojo", which is like a hobby club where kids can learn programming. Some kids go to soccer, others to art academy — and these kids learn programming. Super cool to teach.

However, most kids get stuck after they master Scratch. Especially kids around the age of 8–10. They learn Scratch. It's awesome. They make some advanced games and really get the hang of it.

Then they ask to do something more — some “real programming.” And that's where the hurdles start to pop up. First problem: my kids don't speak English, so most documentation and tutorials are out of reach. Second problem: suddenly they need to learn everything about computers — source files, graphics, networking... This is too big a hurdle for them to take. Third problem: text-based programming. Most of them literally can't type on a keyboard properly. Text is also much less fun than visual programming.

What I've always wondered — and this project reminds me of it — is: can we make the transition smoother? Stay within the Scratch ecosystem, which they know, but start introducing extra concepts step by step, without the big jump.

GoboScript introduces "text-based programming" as a first step, while staying within the Scratch world. I would have liked it more if we could teach the kids a real-world programming language, like Python or JavaScript — because then they’re moving toward "real programming" step by step.

The next step would be: introduce other computer concepts like file systems or networking.

I would love to build this myself. Alas, no time. Maybe one day.

This is how I learned a long time ago with Game Maker. Everything was Gui based, but you could also add code blocks to do more powerful things.

Eventually, most things I built were nothing but code blocks.

If I'm reading that right the Battery Electric busses had the lowest maintenance costs? The need to charge is a potential issue, but at the same time busses do lots of low speed stop and go where battery systems are most efficient. As long as the bus has enough capacity for an entire day and can be recharged overnight it seems like an ideal solution, minus of course the up-front cost of the bus. Lower fuel costs, no noxious pollutants, less noise, lower maintenance, there is a lot to love.

It is likely that new models had higher costs, including maintainers becoming familiar. Long-term, electric is unquestionably cheaper to fuel and maintain, assuming they are built to the same standards and scale as outgoing diesel models

We are already on the path to have the grid converted to majority green energy over the next decade. Solar is by far the largest of New deployments and growing annually.

Grid batteries are just starting to scale up.

These are cheaper than any other option by far, with the shortest payback period.
