common lisp style and design, engineering question
|
| |
This is not a hypothetical question. I will be implementing some
applications in the next year or so, such as artificial neural
networks, support vector machines, Baysesian networks (inspired in
part by 'Programming Collective Intelligence' by Toby Segaran who
implements these in Python.)
My day-to-day language is Perl, and C to a lesser extent. I write... more »

PROLOG UNDER THE HOOD - New Prolog Engine!

BEHOLD!
$sql2="SELECT HEADS.id AS 'HID', QUERY.buds AS 'QB'
FROM QUERY INNER JOIN HEADS
ON QUERY.ref=HEADS.ref AND QUERY.term=HEADS.term
GROUP BY HID HAVING COUNT(HID)=$qc-SUM(QB)"
This is what makes PROLOG DATABASES possible: the flux capacitor! It's
taken me nearly thirty years and my entire family fortune to realize... more »

Decoding large, nested json and inserting into a database
|
| |
Hi,
I am trying to figure out a way to parse nested JSON and insert various extracted elements into an sqlite database. The JSON strings are typically quite large, and rather than parse them entirely into memory first as Lisp objects (alists or CLOS objects) I would like to be able to do this in streaming fashion, as the JSON is being read.... more »

Permuting array rows
