There is a huge difference between refusing to cooperate and forbidding the making of film altogether. The U.S military doesn't have the power to restrict freedom of speech. Of course no organization would want to be portrayed in bad light. That is obvious. But unlike China where everything has to be approved by their authoritarian government, we have freedom of speech laws that protect us.

Fast transfers are not something that cryptocurrencies uniquely enable, so I think it is unfair to highlight that as a feature.

Transfers could (and often are) instant without cryptocurrencies too. Inside Europe most transfers clear within minutes.

The main reason why some transfers are slow is due to KYC rules which cryptos do not implement. With the same procedures in place, they'd be just as slow.
Surely worthy of a black banner.

I have worked with it a bit in my time in physical layer test and measurement.

I’ll cover some quick basics then explain why chirp z is useful.

Ohm’s law: voltage = current * resistance. Resistance is considered a steady state value. Impedance is resistance across frequency. In the real world channels (cables, the air, etc.) do not have a flat impedance (the same resistance across all frequencies). Similarly, transmitters and receivers do not have flat resistance. If you try to send a signal through a channel that has too much insertion loss, then the receiver won’t be able to decode it. If the impedance of a transmitter/receiver is different than the channel there will be reflections that damage signal integrity (there are good/easy physical analogs to explain this, but I won’t. Think back to waves in physics class).

We can measure impedance over frequency directly using a vector network analyzer (VNA) or a time domain reflectometer (TDR). A VNA sweeps across frequencies and listens to the response. A TDR sends a pulse then waits for the response at a given delay. It sends many pulses and looks at many delays to build up an impedance over time plot. This impedance over time is very useful because it can show jumps in impedance at given electrical lengths. Like you can see impedance jump at 30 ns in where you expect to have the connector soldered to board, etc. However, TDRs compared to VNAs, are expensive, difficult to calibrate, and take data very slowly. So the industry has moved towards VNAs. However standards bodies (like the IEEE) are starting to appreciate the use of time domain impedance.

Now to why chirp z is useful. You can reversibly convert from the time domain to the frequency domain using a fourier transform. Great. You just have to assume that your signal repeats for all time. Hmm. Zero pad and don’t worry about it. What do we not get from this assumption though? Low frequency information. So let’s start with a frequency domain data set (a la VNA) and convert to the time domain. Well that missing low frequency information is very important. You can extrapolate the missing values. The error in the extrapolation will shift your entire impedance profile by huge amounts. In comes chirp z. It is able to handle the missing spectrum much better than the fourier transform.

To summarize: validating new hardware before mass production requires impedance measurement. Impedance measurement has two instrument options with large tradeoffs. Advancements in the chirp z algorithm reduce the penalties of one of those options.

This is nonsense. The U.S military doesn't fund the U.S film making industry. The result is different, there are plenty of films critical of the U.S armed forces. In contrast that's not even a possibility in China because they have no freedom of speech and censorship is ubiquitous.
Sounds like an apple problem, not a problem of us power users who moved to something better.

For bidirectional communications you need to transmit, and this means you send out a signal that can be easily triangulated.

> Doesn't Elixir on Phoenix[1] provide the elegance of Ruby on Rails without its drawbacks?

I'm not sure I would say elegance is the main feature of Rails, but I think productivity is. IMO nothing out there beats Rails in terms of productivity on a new project. Phoenix is clearly inspired by Rails, but if you'll permit me to pull a semi-random number out of my ass I don't think Phoenix will ever be able to do better than about 80% of Rails's productivity. Some things are just not as simple (for example, just due to the nature of things Ecto is not as simple to write with as ActiveRecord is).

That said, I've totally moved away from Ruby on Rails and over to Elixir/Phoenix for my stuff. I absolutely love Elixir. So far in my experience I'm finding it more performant, easier to maintain, but a little less productive to write in. But still plenty productive enough.
From what I heard, it's specifically CalFire that's terminating no-fee access to HAM repeaters on mountain tops. I'm sure Verizon and ATT love this. Personally, I hope this spurs interest and activity on the 40m and 80m bands.

Java had to rewrite the memory model of the whole JVM when they introduced the concurrent package.

Even C++ has a hard time making good use of concurrency and threads because of locking.

My hunch is that because of the way memory works there is no benefit for non GC languages when implementing threads and concurrent memory over many cores.

A virtual machine does not have to simulate real hardware. So long as it processes instructions and has a state it can be a VM.

DosBOX is an example of an emulator. It is not an implementation of DOS, it just pretends enough to trick games to run. Emulators usually just translate high level semantics without simulating the real system in any way.

It’s rather hard to meaningfully measure any of these figures.

Startup you can measure, but the optimal tuning for faster general operation may start up slower, so now you might want both figures. And then you’re getting perilously close to development considerations, so once you’re doing that surely you should benchmark any required compilation, and so on.

Warmup is even harder to handle well, because it introduces another dimension; even if you were presenting just a single-dimensional figure (which you’re not quite), you’re now wanting to consider how that varies over time while warming up, so now it’s at least two-dimensional. But unless warmup takes ages, you’ll find it hard to get statistically significant figures, because you have so many fewer samples in each time slice.

Total installed size? Problematic because the number isn’t meaningfully comparable, as this is a minimal test, and a number in that scope gives no indication of how much is due to the environment (e.g. JRE, CPython, &c.), and how much further growth there will be as you add more features. People will also start arguing about what should count; if for example you count the delta from a given base OS installation, then you’re providing an advantage to something that uses the system version of, say, Python, and penalising something that requires a different and extra version of Python.

Memory usage? Suppose you pick two figures: peak memory usage, and idle memory usage after the tests. Both are easy to measure, but neither is particularly useful. Idle memory usage, similar problem to disk usage, and so the numbers aren’t usefully comparable. Peak memory usage is perhaps surprisingly the more useless of the two, because the increase in memory usage is strongly correlated with how many requests are being served at once—and so a slower contestant might artificially use less memory than a faster one; and so if you wanted those numbers to be comparable, you’d need to throttle requests to the lowest common denominator, which could then be argued as penalising light memory usage patterns.

The Key quotes:

> Mr Urmson now talks of self-driving cars appearing gradually over the next 30 to 50 years. Firms are increasingly switching to a more incremental approach, building on technologies such as lane-keeping or automatic parking. A string of fatalities involving self-driving cars have scotched the idea that a zero-crash world is anywhere close. Markets are starting to catch on.

> The most general point is that, like most technologies, what is currently called “AI” is both powerful and limited. Recent progress in machine learning has been transformative. At the same time, the eventual goal—the creation in a machine of a fluid, general, human-like intelligence—remains distant. People need to separate the justified excitement from the opportunistic hyperbole. Few doubt that a completely autonomous car is possible in principle. But the consensus is, increasingly, that it is not imminent. Anyone counting on AI for business or pleasure could do worse than remember that cautionary tale.
Yeah but have you walked around Shanghai and asked random people questions.
The benefit is that for profit companies have incentives for quality that public entities do not. In New York, at least ConEd gets you reliable power. The New York subway by contrast is literally struggling to hit 70% on time performance.

It’s a simple calculation. Would you want your local (almost certainly public) transit operator to take over your electric service? I’d suspect in the vast majority of places, the answer would be no.

The ClojureScript example is great.

Clojure and by extension ClojureScript has a lot of tasteful and pragmatic design decisions, e.g. the use of the threading form and implicit lambda illustrated with the "+ 2").

By contrast Racket has been extended to include a Clojure-inspired threading as a library, showing off just a little of its awesome linguistic extensibility, leading in this case to ergonomically similar code.

Clojure/Script is a wonderful opinionated modern Lisp; Racket is a more linguistically extensible modern Lisp. There's considerable cross-fertilisation going on.

If you love Clojure, it's worth keeping an eye on Racket.

You can spell λ out as lambda in Racket (and Scheme).
There are a LOT of things like that. Travel is a good example.

For people making a living wage, some think “I don’t have the money to travel.” Then when they have the money, they think “I don’t have the time to travel.” They don’t really travel until they retire, and then they have trouble going anywhere that isn’t friendly to their knees and faltering eyesight, so they buy an RV.

Others travel in college from hostel to hostel. When they get work, they negotiate longer vacations to travel, or they deliberately become giggers so they can travel.

I met a couple in Thailand who climbed, they worked five months a year around the clock as nurses, and climbed seven months a year literally everywhere. They lived on the cheap so they would have more climbing days.

I have similar stories about people who ride bicycles and dive. If you are passionate, don’t wait for some magical day when you can fly the Concorde to go climbing in Europe with your friends (true story about some Yosemite dirtbags who came into illicit cash).

If you’re passionate about a thing, go do that thing. Now.

So, if they wanted to prove that a human can run a sub 2 h marathon distance, then why is not the entire doping arsenal in play? Similar, one could probably improve on the record by driving behind the runner with a car with an really big fan. Neither of that was done to prove that a human can run sub 2 h. My argument is now, that would shatter the spectacle. The NYT would not report on the first fan assisted sub-two hour marathon run, so they don't do it because their ultimate goal is the NYT headline "Eliud Kipchoge Breaks Two-Hour Marathon Barrier."

I think the point of a high-level language is to make your programs shorter. All other things (e.g. libraries) being equal, language A is better than language B if programs are shorter in A. (As measured by the size of the parse tree, obviously, not lines or characters.) The goal of Bel is to be a good language. This can be measured in the length of programs written in it.

Lisp dialects have as a rule been good at making programs short. Bel is meant to do the same sorts of things previous dialects have, but more so.

It's also meant to be simple and clear. If you want to understand Bel's semantics, you can read the source.
I think researching autonomous cars but continously extracting and bringing the "easy" accomplishments to market, like automated parking, is the more successful strategy. This is what many traditional car manufacturers and to a lesser degree Tesla seem to be doing. Others like Waymo want to skip all intermediary steps and go straight for the big prize. That's a high risk strategy that may or may not pay off.

I was thinking the other day that I would pay for a service delivering a car for me on-demand, for me to drive, (don’t need a self-driving car when I can drive) and then just leave wherever I am when I’m done. It seems it should be more or less practical to deliver such a service using remote controlled cars.

Most of California is a tinderbox. In late summer, when you walk in brush or in the woods, the ground 'cracks' as you walk - from dry sticks and pine needles. California burns every year. Fires have started from car exhaust pipes, people dropping a cigarette, knocking over a camping gas stove, etc. The solution isn't to ban "camping gas stoves" - the solution is to have fire breaks BEFORE the fire. Fires get out of control in California because of it's massive size and fuel source. Why do people blame PG&E? Would we all feel better if it was a kid playing with a magnifying glass? The solution is to destroy the main electrical company? We would all be happier if they were government owned electrical lines that caused the fire? I don't follow the logic.

I am sure PG&E will enjoy slashing all their current (and past??) employee retirement benefits. Who wins here?
Hey Chris :)

I totally get you with Lisps and performance, but I was more talking about the beauty and elegance of code written in them. Algorithms written in Lisps seem to be pieces of art.

And that's just Lisps... having a look at logic programming languages like Prolog and Mercury, it's amazing to see just how compact yet understandable an algorithm can be. They're beautiful!

But as for performance, take a look at Mercury - its a declarative logic programming language with built in constraint solving, which compiles down to C, and its performance is great. We've rewritten some Mercury in Rust, and yes our Rust is faster, but not by orders of magnitude as you'd think.
Perhaps you should ask the first adopters who paid a premium for the Apple Watch Edition (Gold), Chromebook Pixel and the Samsung Fold to see if they are still using them.

What's worse is that first adopters are at the very start of the planned obsolescence process and even by then, the hardware/software is made completely useless as soon as support is ended unlike Windows PCs which are still useful after end-of-life.

Do you think it is worth paying a premium for the first edition of a un-upgradeable product?
