Can confirm, it's a great way to get started with radio stuff. Since I live in Europe, I did this with the German DCF77 signal. The frequency is low enough that you can do direct sampling with a 192ksps sound card or with an RP2040.
A nice thing about DCF77 is that once you manage to receive the amplitude modulated signal, you can move onto decoding the slightly more advanced spread-spectrum phase modulated signal, which carries (almost) the same data.
You can start by buying a time signal receiver module, and once you confirm that the module can receive the signal, cut off the ferrite antenna and use it with your own receiver.
I think it's a very nice concept, but sometimes when you present, you have to use other people's computers, and I am wondering if it's possible to generate a PDF from this and use it for presentations?
My second thought is that something like this could be made as a LaTeX package, similar to Beamer. For scientists, there are many benefits to using LaTeX for presentations.
If I'm understanding it correctly, I think it renders your presentation to an html file that you can just open in a browser. I assume the effects and transitions are all powered by embedded JS. So it should be portable.
Charging an EV is straightforward if you have a home parking spot. However, "According to the 2017 American Housing Survey, 66% of all occupied housing units in the United States had a garage or carport."
For those living in big cities and relying on street parking, EVs are still less practical. I envision a service where you leave your car parked on the street and schedule a mobile charger through an app to come and charge it while you're away.
Add driveway to garage or carport, but I get your point.
Individuals can’t install them, but cities or parking garages can. Level 1 or 2 chargers down a city street makes more sense the more EV adoption increases.
Right now only 1% of cars on the road are EV’s, but EV’s and plug in hybrids are 18% of new car sales. Even if adoption stalls we will still build a lot more EV infrastructure, which then makes EV’s more attractive.
This is a wise short-term solution to prevent potential legal exposure. Long-term, I think we will need to figure out how to deal with IP in AI-generated code.
I get a bit annoyed when people focus too much on the "functional" aspect when discussing Haskell. True, it's a significant part of it, but there are other functional languages that go back as far as Lisp. What sets Haskell apart from these languages is its strong typing, lazy evaluation, algebraic data types (along with supportive matching syntax), and many other small language features which together make it a really nice language.
Some other features I really miss from Haskell when programming in other languages are the dedicated function composition and application operators, curried functions by default, and support for partial application of operators.
I program Haskell every day and don't feel like I've been shoehorned into being "an architecture and abstraction astronaut". I do feel I've been gently nudged away from worst practices[1] though.
Could you elaborate more about what you mean, maybe giving some examples?
Maybe just scarring from working with haskellers who are writing c++. The project has been delayed probably months due to shitty abstractions. Has never met a self imposed (generous) deadline. They keep breaking the up stack contract that I depend on. Why they didn't just choose c for this project is infuriating.
Literally was in a meeting where a new hire was given the green light because "she was a language lawyer but not enough of a language lawyer to get in the way". Fuck that.
That doesn't set Haskell apart at all. Rust is the same. You have to first understand what programming patterns are strongly discouraged because they don't work well with the borrow checker (for good reasons!) and therefore best avoided.
Given the easy availability of so many titles, we clearly need better ways to find what to read. We don't want to be at the mercy of big publishers' marketing machines telling us what to read. I spend a lot of time looking at Amazon and Goodreads recommendations, word of mouth, and books mentioned by authors I like, etc.
Another issue with these forms is that the communication method is asymmetric. You fill out the form to contact the business, but their only way to respond is by sending you an email.
And then the email has a “noreply” address. Earlier this year I had a whole conversation iteratively submitting the same unidirectional contact form for each turn of dialogue.
Installing a WiFi client certificate (in lieu of a PSK) and installing a root certificate used for TLS (in lieu of those distributed with the OS) are two completely different things, no?
I think if you block port 443 in such a way that a client sees it closed like any other non-HTTPS website, and the user has never been to the requested site before on that browser (to avoid HSTS being in effect), and they omit a scheme when typing the URL into the address bar, then the browser will make an unencrypted request and render the unencrypted response. However, popular browsers these days will add a "not secure" note near the address bar (where historically it would've had no such indication besides lack of padlock) and they'll try https first before falling back to http (but no fallback in the case of cached HSTS info from a prior visit).
