How has DeepSeek improved the Transformer architecture? This Gradient Updates issue goes over the major changes that went into DeepSeek’s most recent model.

Finally found a concise and comprehensible overview of DeepSeek v3

A recipe for improving SQLite concurrent write performance:

1. PRAGMA journal_mode=WAL;
2. PRAGMA busy_timeout=5000; or higher.
3. PRAGMA synchronous=NORMAL;
4. Keep write transactions small.
5. Avoid write-after-read transactions.
6. Use app-level locking if needed.

There is nothing easier than writing something you want to write, and nothing harder than writing something you don't want to write.

My new post explores how SQLite handles concurrent writes

Wait, there is a podcast on python internals? Please keep it up guys! I've gone listening to all the episodes.

And if you wanted an overview of how SQLite works, here it is, a lecture by the SQLite creator www.youtube.com/watch?v=ZSKL...

Benchmarking SQLite Performance in Go SQLite has a reputation of being a toy database useful only for hobby projects and integration tests. I’ll show you why this is not true, with data to back it up.

An article on this: www.golang.dk/articles/ben...

Benchmarked this on mpb 2021 inserting 1KB blobs. Each insert is a separate transaction.

Explanation: SQLite is known to have limited concurrency. It uses a global lock to sync writes. With too much contention it's less efficient than, say, a go mutex because it's a file lock.

SQLite can give you an excellent write performance, e.g. ~70k inserts/s. Concurrent writes are ok, but if you have too much concurrency, performance drops, e.g. with 128 threads inserting, it's ~3k inserts/s . There's a trick: use a mutex to sync threads, same 128 threads give ~50k inserts/s.
