Theme author here! I designed those for a few of my C++ programs years ago, back before FLTK had high-DPI support. (I wasn't involved with porting them to fltk-rs, but I'm glad FLTK for Rust has them available!)

At 100% scaling, they look they way they're supposed to.[1] But at other scales, particularly non-integer ones, their drawing code will need updating to use the new fl_override_scale()/fl_restore_scale() API.[2] (Now that 1.4.0 is officially out, I expect to get back to maintaining those programs.)

Experience: 3 years full-stack fintech development; 2 years academic research; various web development; BS+MS in Computer Science

I've worked on a variety of projects in the past few years, from web app frontends and backends to an automated trading system, as well as retro assembly programming in my spare time (it's the polar opposite of Java+Spring's high-level abstraction). I'm seeking full-time employment but would also be open to short-term positions.

From the article:

> There's an open issue for something like this: Variadic generics[1]. But so far every attempt at an RFC has been closed or postponed.

With C++17's compile-time conditionals, plus good old C preprocessor macros, you could do this:

    #define MATCH_VARIANT(x) [](auto& x)
    #define CASE_VARIANT(x, T) constexpr (std::is_same_v<std::decay_t<decltype(x)>, T>)
    
    MATCH_VARIANT(arg) {
        if CASE_VARIANT(arg, string) {
            printf("string: %s\n", arg.c_str());
            // ...
        }
        else if CASE_VARIANT(arg, int) {
            printf("integer: %d\n", arg);
            // ...
        }
        else if CASE_VARIANT(arg, bool) {
            printf("bool: %d\n", arg);
            // ...
        }
    }
(MATCH_VARIANT could be extended to allow capturing vairables, or just omit that macro, it saves less typing than CASE_VARIANT anyway.)

I left Stony Brook University in 2017 with a Master's in Computer Science, and am currently seeking a software development position. I'm open to contract, part-time, or full-time opportunities. I care about writing code that's not just correct, but documented for the developers' sake and designed for the users' sake.

As the paper's abstract states, "Quadratic cost uniquely makes the marginal cost proportional to votes purchased". The full paper shows their proof and the assumptions behind it, such as "an individuals’ value for votes is likely to be approximately linear in the number of votes she casts so long as her utility is driven by the impact she has on the vote total, as argued by Mueller (1973, 1977) and Laine (1977)".

If merely 100 less-wealthy voters out of the whole population couldn't coordinate to buy a few extra votes—and they wouldn't even have to explicitly communicate, it would just take 100 people who individually hear about the issue and decide to vote more—then how important can the issue really have been to them?

I believe this is what is meant by "the collective decision rapidly approximates efficiency as the number of voters increases".

Sounds like the system would be doing its job in that case.

That translates fairly well into Python, with its set type and list/set/dict comprehensions.

    def setrange(first, next, last):
        return set(range(first, last+1, next-first))
    
    fizz = setrange(3, 6, 100)
    buzz = setrange(5, 10, 100)
    fizzbuzz = fizz & buzz
    fizz -= fizzbuzz
    buzz -= fizzbuzz
    num = setrange(1, 2, 100) - fizz - buzz - fizzbuzz
    line_map = dict({n: "Fizz" for n in fizz}.items() +
        {n: "Buzz" for n in buzz}.items() +
        {n: "FizzBuzz" for n in fizzbuzz}.items() +
        {n: n for n in num}.items())
    for i in range(1, 100+1):
        print(line_map[i])
Some SETL features Python lacks:

• No ellipsis notation for ranges; must use the "range" function and add one to the maximum value, or define a custom "setrange" function

• Can't concatenate dictionaries; must concatenate their "items" lists and convert back to a dictionary

• No consistent map-lookup notation; collections are indexed with brackets, but functions are called with parentheses

"Chat stories" with "comic-book inspired" young-adult plots, made to be read on mobile phones... Sounds like they've reinvented Japanese cell phone novels[1]. Sci-fi/fantasy YA plots are also common to light novels [2].

From the Google Maps & Earth Help Forum[1]:

> Why does Google maps use the inaccurate, ancient and distorted Mercator Projection?

> Maps uses Mercator because it preserves angles. The first launch of Maps actually did not use Mercator, and streets in high latitude places like Stockholm did not meet at right angles on the map the way they do in reality. While this distorts a 'zoomed-out view' of the map, it allows close-ups (street level) to appear more like reality. The majority of our users are looking down at the street level for businesses, directions, etc... so we're sticking with this projection for now.

Apparently those are names for 50 and 100 BTC.

From this presentation[1] or the source code[2]:

    1 Lovelace = 1 Bitcoin
    1 Goldwasser = 10 Bitcoin
    1 Rackoff = 25 Bitcoin
    1 Pedersen = 50 Bitcoin
    1 Williamson = 100 Bitcoin
But yes, those are meaningless names in themselves. Metric prefixes like "hectobitcoin" would be better.
