a small laser engraver perhaps? looks like you can get one from china close to 100usd

Genau! Haha...

See how Docker and Docker Compose can help you create reproducible ROS 2 environments. This includes the ability to configure variables at build and run time, as well as creating dev containers to help you develop your code in these environments before distributing it to others.

How would you do a binary search on a continuous space without discretizing?

hmm, could be dns blocking by your ISP. Try changing your DNS server to 8.8.8.8 (Google)

edit: seems to work now, don't know what's changed

Been reading the docs, very impressive amount detail! However I had some issues accessing the docs from work, something about DNS-malware something from my IT department. Anyone else had similar issues?

Do you have a source for those fast reboots? It's running Linux after all

NICE!

it's kind of funny to keep it too :-)

used jabref myself a lot, mainly because it's easy to understand how it works (all state is in your .bib files). never really missed any features.

hilarious demo video

Unfortunately does not cover all aspects of travelling. Might need required safety equipment etc. But for people hiking I agree :-)

If the nodes have GPS it's fairly straightforward to calculate distance and bearing.

Haha, great article! too bad the video is unavailable :-(

What do you mean LQR is suited for non linear systems? This is all misinformation. LQR is a linear systems tool.

The nice thing about linear systems is that almost every dynamical system is locally linear near some operating point.

Just started watching it. Heartbreaking.

Para/hang-gliders, small drones, birds. There's plenty of stuff you don't want to hit :-)

Elsykkelbutikken.no imports directly from China. They are super helpful.

Ten hours is a lot. I've mounted two similar kits. Both took less than four hours.

I can comment on the range. I have a similar bike with a 540Wh battery. Total weight close to 20 kg, maximum practical range approx 30-40 km. Slightly less when sub zero C temp.

Edit: I would consider an extra charger and charge at work for that range, in case you want to stop by somewhere on your way to or back from work.

Also year-round commuter in Norway w/ an e-bike. I agree that the increased speed increases the probability of an accident. I've personally had several close calls vs cars in roundabouts and on bike lanes (!).

I also have a motorcycle license and I've been riding motorcycles for about 5 years in traffic. A lot of the risks are very similar to the ones you experience on an e-bike in my opinion.

Edit: The best tip I can give to two-wheel riders is to increase visibility as much as possible, and be observant of cars. Lights and bright colored clothing helps a lot.

I'm on my second converted (bafang) e-bike, been riding about 4000 KM the past two years all year (Norway). I love it! I use it as my main means of transportation, both to work and for other transport needs.

My first one was a cheap/old 26" dirtbike with hydraulic brakes. It was OK but the front shock and relatively skinny wheels were a limiting factor.

My second bike is a mid/high quality 27.5" dirtbike with a good front shock and good hydraulic brakes. And it's a really good bike all year. I highly recommend getting fairly large wheels with wide tires and a good front shock for a conversion bike.

My battery is easily removable and has a handle. When you are riding a bike you usually don't carry stuff that you have to use your hands to carry. I always have a backpack. In any case I always have at least one hand available to carry other stuff.

I charge the battery in my entry at home every day, but I could probably charge it only once or twice a week and that would still be sufficient.

hæ?

Thanks for the additional information, I completely agree with your description of coverage and the graceful degradation of FM.

DAB has obviously arrived and is here to stay in Norway, but I'm interested to see what the rest of the world does. My guess is that internet connected vehicles will be a both cheaper and better solution for consumers in many regions. Given the amount of data people use on their phones today, it seems likely to me that providing audio streaming of DAB equivalent bandwidth is feasible - even in Norway.

Ok, great answer. I live in Norway btw.

Both the constructive interference and reduced number of transmitter arguments sound reasonable. I'm a bit more skeptical to the power cost, how much more expensive can that really be for FM? Electric power is pretty cheap. Does not really matter what the answer to this is though, given the other arguments.

At the moment I have to say I'm not very impressed with the coverage and quality of DAB in Norway, in my opinion it seems worse than FM. But I'm guessing this will only get better over time.

My main issue with the adoption is the requirement to buy new receivers, it's just so much waste. The adapters they sell for cars are in general just so ugly and a technically inelegant solution (local FM broadcasting, pretty ironic). A funny anecdote I read in the news was that some of these adapters come with a bluetooth handsfree solution, which also gets broadcast locally on FM. This means that other people driving close to you can listen in on your conversations if you use that functionality.

Do you have a good source on the cost diff?
