I don't think anybody equates Python with execution speed. Writing web applications in Python facilitates rapid development, and since most of the web applications are io bound, slow execution speed doesn't make noticeable difference.

I think employers will be interested in hiring you for such projects only if you have demonstrated knowledge and experience in the field. If your work experience primarily consists of RoR web development, most employers will pass. It's not

My bad. I was speed reading, and didn't read the "Closure Table" part.

That will prevent a child being its own parent. It won't work for more than one level i.e a post being its own grandchild. Assume (post_id, parent_id) sequence: (1, 3) -> (2, 1) -> (3, 2).

I think if you want the family tree, you can write a self referential(assuming post table is self referential as it should be) recursive query. But in this case, writing a before insert/update trigger which ensure some_post.created_at <

How are you modelling your data? I think this should be a self reference. create table post (id int primary_key, parent_id int references post(id), child_id int references post(id), created_at timestamp) How will you place the chec

The kind of assertion he needed could not be ensured by the database. The kind of assertion he needed was there are no cycles in the graph. How would you ensure that in a database? Also, HN uses flat files, not database.

by irahul 14y ago
HN runs on plain files. He wasn't modifying database, but calling functions(I believe) in the repl to change the parent id of the thread. But that apart, even if there were an admin button to change the parent id of a thread, he would still

This is a bit arrogant and misguided. As another commenter pointed out, if you go to a hair dresser, you do get suggestions about what will look good on you, but the hair dresser won't refuse service if you go against the advice. As a devel

It's not about being protective over DDG. You are being an asshole again and again in this thread. By your admission, you don't have any experience with search engines, and yet you have definitive opinion about everything related to it.
