I had to deal with it, when I hadto parse Transac-SQL code, and it's not handy. Very difficult to have a single executable file containing everything, it needs a whole subtree. OCaml is easier with Opam and ocamlbuild tools.

For normalization, for instance : Select stddev(col1)/avg(col1), stddev(col2)/avg(col2),... from mytable group by key. One line.

I use to write complex SQL query very usually, and I can say that it's far more concise than imperative code. Compared to it's own semantics, SQL is actually verbose, but its semantics is so powerful that you gain size.

I think most of the problems come from insufficient semantic power of actual language. Most programming language, even the most advanced don't manage time, don't manage locality, and don't fit in the brain representation huma

* The text research feature : it highlight what you search for and you can switch to a regexp. It works well with1G+ log data * You can set a color for each tab, so you instantaneously target the good ones * You have an history replay * Pic

There's an interesting language strongly influenced by Self : Lisaac ( http://www.lisaac.org ). Lisaac is a purely prototype language extending the Self's prototype paradigm with extremely good performance (close to C

Using MagnetoHydroDynamic, you can. You just have to use parietal Engine invented by Jean-Pierre Petit in 1975[1]. With this technology you can fly at Mach 8, easily.. [1] https://www.youtube.com/watch?v=Jn8b3E9oUHY

Every programmers should know something about memory, because software are becoming bloat [1] [2] because of a new generation of programmers who doesn't optimize their code. So, of course, you had a wonderful career, but it doesn'

Some years ago, I had to write program that extract a foot pressure platform for an orthopedist, and I had to do it with a closed-source Delphi API. Delphi was already old at that time and difficult to find. I though about Lazarus and it wo

I wonder if this very clever approach is interesting in the energy consumption perspective. In this work ( http://hpc.pnl.gov/modsim/2014/Presentations/Kestor.pdf ) the author shows (slide 11 ) that it cost 10

Using PostgreSql, I tend now to directly generate query result in json. It implies an architecture model where you put the business logic and type safety in the RDBMS. It reduces the number of layers for a lot of functionalities.

I think all experiments of languages that resembled natural languages will never work until one will try to ascend to a more high-level paradigm. Actuals programming language are based on a "forklift paradigm" : you describe the p

Good point : there's no parser inside the lexer, like PHP ;-)

Several possibilities : - A very clever and complete type analysis. The compiler can thus optimize at best the code without runtime type-checking code. - If possible, a flow analysis : By analysing the bounds of each function, compiler is a
