A Reader’s Question on Nested ListsA Reader's Question on Nested Lists | CSS-Tricks A couple of days back, among the tens of crypto-scams that flood our contact inbox, we found an interesting question on nested lists from one of our readers. I have a problem (related to list-numbering) that seems commonplace, but I can’t seem to solve it or find any solution for. If any of your geniuses can answer...0 Σχόλια 0 Μοιράστηκε 248 Views 0 Προεπισκόπηση

An Efficient Way to Check for Existence of Multiple Values in SQLWhat's faster, COUNT(*) or COUNT(*) with LIMIT in SQL? Let's check In a previous blog post, we’ve advertised the use of SQL EXISTS rather than COUNT(*) to check for existence of a value in SQL. I.e. to check if in the Sakila database, actors called WAHLBERG have played in any films, instead of: SELECT count(*) FROM actor a JOIN film_actor fa USING (actor_id) WHERE a.last_name =...0 Σχόλια 0 Μοιράστηκε 263 Views 0 Προεπισκόπηση

Better CSS Shapes Using shape() — Part 1: Lines and ArcsBetter CSS Shapes Using shape() — Part 1: Lines and Arcs | CSS-Tricks Creating CSS Shapes is a classic and one of my favorite exercise.

Getting Top 1 Values Per Group in OracleOracle's way to get multiple values in a top 1 per group query I’ve blogged about generic ways of getting top 1 or top n per category queries before on this blog. An Oracle specific version in that post used the arcane KEEP syntax: SELECT max(actor_id) KEEP (DENSE_RANK FIRST ORDER BY c DESC, actor_id), max(first_name) KEEP (DENSE_RANK FIRST ORDER BY c DESC, actor_id),...0 Σχόλια 0 Μοιράστηκε 282 Views 0 Προεπισκόπηση

Resisting the Urge to Document Everything EverywhereWhy I don't document quirks of a feature on the feature itself. Every product manager knows this situation: A user works with feature X1. They find a limitation / bug / quirk and want to work around it. The perfect workaround or alternative is feature X2, but without knowing that X2 exists, the user doesn’t find it and spends a lot of time looking for it. The user requests X2 be...0 Σχόλια 0 Μοιράστηκε 300 Views 0 Προεπισκόπηση
