array 的長度不會變,如果一開始不知道資料長度的話,需要另外設計 collector。 陣列就只有一個長度,但收集器有兩個,一個是資料,另一個是緩衝區。長度改為可變,讓收集器能夠增加 element。 為了與其它模組共享記憶體緩衝區,收集器能把內部資料變成陣列。

Except you should never use a dynamically resizable array, hashmap, or linked list. These are banned in my codebases. Learn static arrays, pools, and spsc ring buffer queues. Learn AoSoA and SoA. These are your fundamental data structures if you want good real-time performance.

Every programmer should spend time building all the fundamental data structures from scratch (dynamically resizable array, hashmap, linked list) Actually learning how they work and the specific implementation tricks is 10x more valuable than just knowing their Big O complexity

however, it doesnt allow further writes to absolute mem addr. For dis, it is nec to compute arbitrary offsets but how? If it was unbounded #ArrayBuffer object in #Javascript, one can write arbitrary js to directly calculate but herein it is single-pass img parser.. 7/n

OK JS & ECMAscript committees please tell me, why did the ArrayBuffer / DataView functions have to be so.... complex? I've done a lot of bit and byte handstands in ASM, C, Python, etc. But this is some seriously verbose grammar. #javascript #arraybuffer

Interesting stuff! So to optimize the encryption process in the browser, I'm going to use #TypedArrays (#ArrayBuffer) + #IndexedDB , so the encryption process goes without loading the whole file in the memory. developer.mozilla.org/en-US/docs/Web… developer.mozilla.org/en-US/docs/Web…

I'm happy to announce a couple of nifty libraries for #haskell and #purescript - implementations for the z85 binary encoding (denser than base64): hackage.haskell.org/package/z85 pursuit.purescript.org/packages/pures… The purs one also uses the new bindings to #arraybuffer : pursuit.purescript.org/packages/pures…
