False | Herbstein | t2_au753 | Set my mom down in front of a computer. She's probably more capable than the "average user". If you gave her a text-only interface she'd simply not use it.
I use a lot of text-only interfaces, as I suspect you do too. If you want to refute decades of research you need more than a gut feeling that "the average user has been treated like a drooling idiot". I'd argue that "the average" of almost any group is a drooling idiot. As Churchill is attributed as saying, but probably didn't:
>The best argument against Democracy is a five-minute conversation with the average voter.
And this "drooling idiot" attitude is backed up by research into how people interact with technology. HCI doesn't just have a focus on discoverability, as some people ITT claim, but also on enabling power users to skip the handholding. Do you know how many people use keyboard shortcuts apart from copying and pasting?

> What is "incorrect" about it? Seems to be working for Reddit.
Reddit is not in the 99.9% of sites, it (as well as every other site that serves >100 requests/sec) must make infrastructure decisions that I'm not qualified to comment on.
I've worked on Rails sites where data processing was a large part of request-response time. Written in not-Ruby, the company could have saved most of what they spent on servers. There's a lot more you can say about that (developers cost more than servers, don't write numeric programs in ruby), but it's already been said by others more eloquent than me.
All of this can be ignored as a business decision, often a correct business decision, but it's a cost that should be taken into account. | null | 0 | 1544484062 | False | 0 | ebj0c4p | t3_a4cebi | null | null | t1_ebix8ph | /r/programming/comments/a4cebi/rocket_v04_typed_uris_database_support_revamped/ebj0c4p/ | 1547449026 | 2 | t5_2fwo | r/programming | public | null |

False | michael0x2a | t2_aoqnb | > All those carefully worded commit messages you get in your PR are blown away into a near-useless merge commit message.
I wonder if this is more an artifact of whatever tooling you're using rather then anything to do with git squashes in particular.
For example, I contribute to an open source project on Github that standardized on using squashed merges. Whenever you click the "squash merge" button, Github will open up a UI containing all of the commit messages in that PR concatenated together as a bulleted list. You can either just land the entire PR with that description (suboptimal), or better yet reword the entire message -- make it more cohesive, remove any old text that's no longer accurate...
> Instead, before merging, require people to git reset and create incremental commits based around logical groupings. You may only need one commit. You may need 40. But they should be good
The other alternative is to insist each logical grouping be landed separately. So if you need to do some refactoring before adding some new feature, you'd make one pull request with just the refactor, get that code-reviewed + landed, before submitting the next PR. In this world, the squashed-merge model makes more sense. I suppose the main negative is that you need to fiddle around with git a little more to get "stacked" or "dependent" pull requests -- but I don't think that's too bad, in the grand scheme of things.
That said, I think the other workflow you're proposing also sounds reasonable. I think you get basically the same thing in the end (assuming you actually do require developers break up their work by the "atomic unit" -- commits in your workflow, pull requests in mine.) | null | 0 | 1544485296 | False | 0 | ebj1rgp | t3_a4uynu | null | null | t1_ebicw9h | /r/programming/comments/a4uynu/on_the_importance_of_commit_messages/ebj1rgp/ | 1547449691 | 1 | t5_2fwo | r/programming | public | null |

In "attorney general" the head noun is "attorney" and "general" is a postpositional adjective which is a grammatical feature that is rare in English but nevertheless possible like "knight templar" or "lord spiritual" or "secretary general" and generally considered highly formal style reserved for occupational titles.

Assuming I'm not misinterpreting you and you're claiming that you can implement a function `anySatisfy : (ℤ → Bool) → Bool`, then **no, you definitely cannot do this**, even if you assume the input is a total, computable function. Proof: given a Turing machine `M`, ask if there exists a non-negative integer `n` such that `M` halts after `n` steps. You've now solved the halting problem.
In Agda you can define a predicate `anySatisfy : (ℤ → Set) → Set`, but this isn't a decision procedure.

I do not consider Encapsulation and Abstraction to be "OOP

and encapsulation is nothing but restriction, which happens
in other languages too.
All shell scripts are Neandterhal anyway, so straw man
arguments.

What does that even mean? C uses objects too by the

Inheritance is also limited. Composition is a little bit less limited

I don't really see a huge distinction between OOP and non-OOP;

False | crabbone | t2_e3qdk15 | There are multiple reasons. Some are very pedestrian and immediate, other are less so.
For example, Prolog has simply the best parsers. Once you used DCGs you will never want to use something like YACC or AntLR. This is not a statement about expressiveness (Byson can do better than DCGs for instance), but a statement about ergonomics. You'll want to vomit when reading code that uses something like Parsec or, god forbid, Spirit (the one from Boost).
Prolog is great for showing off by solving logical puzzles by simply stating them.
On a more serious level, conceptually, Prolog is far more advanced in terms of working with data than anything in common use today. I mean, if you think that SQL is the state of the art, then Prologs wins by a land slide, and if you think that something like Gremlin or Cypher are any good, then you probably need to see a psychiatrist... Unfortunately, there's very little done in practical terms to enable Prolog to work with industrial-size data-sets :(
The above means that Prolog would easily beat nonsense like JSON or XML or YAML or TOML or other atrocities that are so ingrained in lives of modern programmers.
It has a very concisely described VM, one that is extremely simple and can be made reasonably fast.

Don't micromanage incompetent developers, fire them. Then hire better people. If you don't trust the people you hire, that reflects on your hiring practices. Standing over their shoulder doesn't make them less incompetent -- it just trains them to learn to look busy.

False | RalfN | t2_31gcu | >Do programmers that know neither of those find go easier to learn than Java?
Yes. The surface area of Go, like Python, is smaller than that of Rust, Java or C++. If it's not your first programming language, you can learn it within a couple of days.
This is a combination of intent (they chose to keep it simple), its age (less legacy cruft than C++), the problems it doesn't try to solve (less ambitious than Rust), but most importantly, it's weak type system (less powerfull than Java). The weak typesystem of Go enables an ecosystem where any junior can read and understand all the code that is written in the language. You don't pay this price in dynamically typed language, since a developer isn't forced to 'formalize' their types, which in the case of a generic, or worse, type reflective algorithm is beyond the scope of most developers. They could write the algorithm, just not put the correct type signature on top of it.
The upside: all code within the ecosystem is very approcable. The downside: not that much interesting code (without generics you really can't). Or better put, it prevents both the good and the bad abstractions in favor of, 'just write the code you need for the problem'.
It's like why women pitch their voice up around the wrong kind of (aggressive) men. Go doesn't make anyone feel stupid or dumb either and its doing this on purpose. It doesn't intimidate, and considering the widespressness of the imposter syndrome, its' success seems obvious. And if they can find a way to open up their typesystem to allow more reusable code to be written, without sacrificing that and creating the abstraction fetish hell that too much freedom can do to an industry or ecosystem, it will be interesting. I personally don't like touching it, but i get and respect its success, and the co-workers that are using it are always very productive and effective using it. | null | 0 | 1545749207 | 1545750120 | 0 | ecisoc5 | t3_a8rptf | null | null | t1_ecgk8cn | /r/programming/comments/a8rptf/i_do_not_like_go/ecisoc5/ | 1548053091 | 2 | t5_2fwo | r/programming | public | null |

It provides a lot of shorthand but ultimately it is the same old imperative garbage that forces you to procedurally build elements with statements and append child widgets by hand.

What is very good in SML is a balance of syntax and semantics, which, it seems, approaching perfection in Haskell. How to compile an AST into intermediate code (LLVM or one's own) is an orthogonal question.
There absolutely no need to compile Haskell into a form of simple-typed lambda calculus. This choice is rather academic. It is absolutely reasonable to consider a Haskell'ish syntax, semantics and the less esoteric core of the type-system, without laziness by default, to be compiled straight into native code, the way Common Lisp does.

'Nice to have' is actually 'nice to not have to maintain' in this world view - with the promise that you'll get your core functionality this way for a tiny, tiny fraction of the code a regular design would produce.
And what if the core requirements change? Well, you throw away that tiny amount of code and build a different, but still tiny amount of new code to address these as well. Could you implement an HTML 5 display this way? Of course not! But in this world view, you wouldn't build HTML5, you would build something much simpler and smaller, thinking about the core problem - say, how to display documents on screen.
Now, I think it's obvious that, even though it might be interesting to live there, this is not our world that I'm describing above, and in reality your programs will have to deal with abstractions built by others that you have no control over. Still, I would love to work with this man once and see what insights he would offer on a project... | null | 0 | 1545749726 | False | 0 | ecit43q | t3_a9e0a5 | null | null | t1_ecimebb | /r/programming/comments/a9e0a5/programming_a_problemorientedlanguage/ecit43q/ | 1548053284 | 28 | t5_2fwo | r/programming | public | null |

I believe that people who don't know how to write should not even try to program.

Sooner or later it comes to the point that I need to explain to them that they don't get it. I do think you have a reading comprehension problem probably exacerbated by your blind rage.
You should not enter discussions with grown ups. You didn't get it. The popular way to reply to your comment would be the all saying "whoosh".
I feel bad for you.
It's like we are playing a game of chess and even before you were born, you already lost.
You don't even know the meaning of the words you use. There is no way to have a conversation with you. It feels like I am talking to an ant.
I can explain everything in simple terms; it's just that I choose not to for well considered reasons. Those reasons would surely also offend you.

False | ejrh | t2_4fttf | From an implementation point of view, there are a couple of points to note.
1. The planner will take some boolean expressions ("quals") from the WHERE clause and move them to other places. For instance, a qual in a join query that only references one table will be applied directly as that table is read, instead of on the join result. Or a qual that can be satisfied by an index will be taken out and used in an index scan.
2. The planner might notice that some of the remaining quals are more likely to pass than others, or more expensive to evaluate, and reorder them to minimise query time. For example, in a table of geographic features, `WHERE overlaps(shape, geography('POLYGON(123 45 ....)')` AND type = 'CONTINENT', could be evaluated in the order given. But it's pretty expensive to compare two polygons for overlap, and almost all of the many countries, and cities that overlap will then have to be excluded by the next qual, which only wants continents. The planner estimates the cost and selectivity of the two functions, `overlaps` and `=`, and chooses a good evaluation order.
Obviously, this is a pain if some quals are only safe to evaluate depending on other quals.
One of the idiomatic ways to ensure you don't get unsafe qual evaluation is to use `CASE`. The [PostgreSQL docs](https://www.postgresql.org/docs/current/functions-conditional.html) say:
> A CASE expression does not evaluate any subexpressions that are not needed to determine the result. For example, this is a possible way of avoiding a division-by-zero failure:
>
> SELECT ... WHERE CASE WHEN x <> 0 THEN y/x > 1.5 ELSE false END;
