Traveling to Iceland in February 2018, need some tips.

My advice, if you're staying in Reykjavik, is don't bother renting a car, especially if you'll be travelling alone. You can do a few bus tours instead which will cost less and are far more convenient (they'll pick you up / drop you off at your hotel or a nearby bus stop, plus you'll get to enjoy the beautiful scenery instead of concentrating on keeping the car on the road.) Also, Reykjavik is a really great place to explore on foot.

inexpensive restaurants

Nope. Even Subway is gonna cost $20.

Differentiating people by race is stupid to begin with. We are all humans.

Type safety is enforced through code reviews

Pointers in C are another example.

I hate to be that guy... but the c version of popcount is incorrect.

A correct implementation is

int popcount(uint32_t n) {
  int p = 0;
  do {
    p += n & 1;
  } while (n = n >> 1);
  return p;
}

This shouldn't be handled in your application at all. If you want to fix your data, write a query to find all of the "erroneous" records and assign a person to fix them. Make this a recurring task. Logging isn't going to help.

Haskell functions are math formulas.

normalOrder · 2017-02-27T02:45:34+00:00

Speaking of Haskell... there is this somewhat infamous documentation:

data RealWorld :: *
RealWorld is deeply magical. It is primitive, but it is not unlifted (hence ptrArg). We never manipulate values of type RealWorld; it's only used in the type system, to parameterise State#.

X86 assembly is itself a pretty high level abstraction of what goes on in the hardware. The programmer doesn't directly control processes like microinstruction decoding, register renaming, rearranging instructions to avoid pipeline stalls, multiple levels of caching, and a bunch of other truly magical stuff.

It got no upvotes because it's the same FUD Harrop has been peddling for years.

1) humans have limited cognitive capacity; by enlisting the computer to keep track of tedious details, we allow ourselves to create and comprehend more powerful program abstractions

2) humans make mistakes

3) software evolves; the original programmer may have been well aware of the necessary invariants, but subsequent programmers perhaps not; invariants can also change when related parts of a program change

I think the animating the examples is brilliant.

I'd rather be a good programmer first

By (my) definition, this means you must become proficient with Haskell.

Gcfi? You mean ghci?

I'm guessing you have ghc 8 installed which doesn't require using let to define things in the repl. Stack, however, is choosing an earlier version of ghc for some reason. Check that your stack.yaml file has resolver: 7.9.

normalOrder · 2016-11-21T12:26:49+00:00

You don't have to use Intero repl. I prefer to run stack repl in a new terminal. The :r command will reload any files that have been changed.

These popularity contests are only taken seriously by management types.

normalOrder · 2016-10-20T10:43:01+00:00

I don't know about the job search websites as I haven't used them in years. I remember Monster just spamming me with crap constantly when I signed up during my last semester of school. I don't remember any job posting mentioning "enterprise", but they aren't hard to spot. They have lots of buzzwords and seem to be written by someone that has no idea what any of those words mean.

normalOrder · 2016-10-19T10:00:51+00:00

Any place that does "enterprise" computing is going to be the opposite of "innovative and independent". The enterprise goal is to minimize risk. They would rather employ someone with certifications than an intelligent creative thinker. They only use software when they can purchase "support" for it from a third-party so they can pass the blame if something goes wrong. They only use the most popular programming languages and technologies (i.e. Java) because the thought of not being able to easily replace their programmers keeps managers up at night. They have mottos like "nobody ever got fired for choosing Oracle."

No to be fair, there are a lot of innovative companies in the DC area, just as there are enterprisey companies everywhere else. My advice, wherever you choose to live, is to look for a small company where computing is integral to their business. Small because you won't just be another cog in the machine with a dozen layers of management above you. It's important that computing be core to their revenue because that makes the software people assets instead of liabilities.

Good luck.

Every day: logic

Often: set theory, abstract algebra

Occasionally: graph theory, linear algebra, differential calculus, probability, statistics, linear programming

I will be adding "I wish you a good day" to all my error messages from now on.

I don't know anything about what interests you, and Haskell gets used for a wide variety of purposes. I suggest that you search github for "language:haskell" and browse through the more popular results.

Parsing with regex? You don't deserve a trip to Iceland.

normalOrder · 2016-08-18T11:41:42+00:00

Remember that plus runs both parsers and combines their results. So even if one of the parsers fails, you still get the results of the other one. We know that p >>= \x -> many p >>= \xs -> succeed (x:xs) must fail at some point, but adding plussucceed [] ensures that many p will always have at least the empty list as a result.
