Are these COBOL programs running on obsolete hardware, or are the systems virtualized these days? I suspect the way forward for COBOL is to modernize the development tools around it, rather then rewrite the code itself.

By "compose in both directions" you mean like arithmetic operators like + and * ? No doubt it is useful to have built-in operators for array operations if you have to do a lot of array operations.

I find it rather weird to compare K to C. In what circumstances would the choice be between K and C? A more reasonable comparison would be between say Python with numerical libraries and K.

Fair point. In any case, if you wanted to do more than trivial array processing in JS, you would use a library like lodash which have an array max function. And if you think lodash is still to verbose, you can define your own: const å =

It is a typical language-comparison strawman. He is writing list.reduce((x,y)=>Math.max(x,y)) To get the max number in a list. And he is "winching" because he can't write: list.reduce(Math.max) Because th

So it is a language with single-character symbols for the most common array operations like map, filter etc. I think the article tries to make it sound more mysterious and groundbreaking than it really is.

Doesn't really change that adding n months to a date is an ambiguous operation. You would need to give all months the same length to avoid the ambiguity, but then months would not add up to a year, which has its own set of problems.
768.
by goto11 5y ago
As far as I can tell, you agree with the articles main point. `plus` is a honest name for adding days to a date but dishonest when it comes to adding months. `advanceMonths` is an awkward but more honest name for adding months. An even more

by goto11 5y ago
Columns are like lists in Python - they can contain values of any type. The type is associated with the individual value.

I think you use "low level" in a different sense than is common. Low level (and high level) typically refer to abstraction level. SQL certainly have a very high abstraction level. But given it is a domain specific language it does

Because in old IE, <h3> was defined with an absolute font size in the built-in style sheet, in newer browsers it is defined as a relative size. Since we have nested <h3>'s they get increasingly bigger in newer browsers, but

The <font size=...> tags are only in the top navigation bar and is not the cause of the increasing text size. The increasing text is due to nested <h3> elements, where h3 is defined to have a relative size. If a font tag automat

by goto11 5y ago
The font-tags are getting unfairly blamed! The increasing size is due to the unclosed <h3> tags combined with unclosed inline level tags. This is parsed into a nested structure, with h3's nested into h3's deeper and deeper.

Some of Dates gripes are valid, but some are quite questionable. In SQL you enforce uniqueness of rows by defining a primary key. Dates concern seem to be that you can have duplicate rows if no primary key is defined, but why would you do t

Shouldn't the normalization rules be exactly the same whether the data is stored row-oriented or column-oriented and on disk or memory?

There are multiple alternatives. Problem is SQL is "good enough" and ubiquitous and deeply entrenched. It will be extremely difficult for any alternative language to unseat SQL.
