5️⃣ Rule of Thumb Speed → HashMap Sorted → TreeMap Concurrent → ConcurrentHashMap Stack/Queue → ArrayDeque


It's a great talk - I may watch it again now that u have posted. AFAIK Rust's HashMap is based on Google's SwissTable

Weakly-Consistent Iterators Used by: -ConcurrentHashMap Behavior: -No ConcurrentModificationException -May or may not reflect updates ConcurrentHashMap<String,Integer> map = new ConcurrentHashMap<>(); map.put("A",1); map.forEach((k,v) -> map.put("B",2)); //Safe


On interviews you might be asked which data structure to choose appropriately for the use case. I'm providing a list and an example for each one: →Fast lookup → HashMap Use Case: Implementing a cache. HashMap provides an instant O(1) lookup using the user's ID as the key…


Javascript、関数のmapはよく使うけど、データ構造のMapをきちんと知らない人結構多い オブジェクトと違って ・順序が保証される ・オブジェクトよりも速い ・利用できる関数が豊富 など複雑なデータの管理に向いた特徴がある 基本的な使い方まとめたので、チートシート的に使って

Sebagai pengguna @PT_Transjakarta, aku merasa perlu membuat versi yang tidak ruwet, informasi, dan mudah dipahami bagi penggunanya. Map Diagram Horizontal Version sesuai arah mata angin Semoga membantu! cc: @jalur5_ @txttransportasi @TfJakarta

Pernah kepikiran untuk membuat sebuah Maps yang bisa ngasih tau lokasi Coffeshop? atau Maps deteksi lokasi mana aja yang ada tempat kost? Kebetulan, menemukan lib js yang ngebantu buat bikin map namanya Leaflet. ini ngebantu bngt utk bisa ngebuat Maps dari Open maps/ Google Maps

Let's talk about JAX's vmap! It's a transformation that can automatically create vectorized, batched versions of your functions... but what exactly it does is sometimes misunderstood. So let's dig-in!

Yang penasaran aku ambil data dan processingnya gimana....aku pake HERE Maps API + python. Google Maps juga bisa sih, apa aja boleh Buat yang mau baca selengkapnya bisa di sini ya megapolitan.kompas.com/read/2022/12/3…

V3 of the Java Developers Roadmap ❤️ Refactoring's based on twitter feedback! Would love to generate this chart programmatically so we can maintain it on Github and see the diffs between releases. Suggestions welcome!

thinking about hash functions inspired me to go read Python's hashmap implementation to see how it works -- it's only 500 lines and it's pretty readable! github.com/python/cpython…
