所以點解負責Oracle, OS support既IT人, 壽命可以俾做編程既長

Yes, but I can imagine the feeling of working with a "dead" platform and hang my career on it.

Assembly Language is still used at least in the following areas

Building device drivers

Of course Assembly is alive, just as Nokia phones are alive. Just nobody cares.

Out of 1000 lines of code written today, I doubt one line of code is in Assembly. It wasn't a main language in the past and it is not relevant as a main language now.

Also, device drivers programs can call OS APIs in modern days.

Assembly Language is still used at least in the following areas

Building device drivers
Debugging
Reverse Engineering
Security research
Performance optimization (the main purpose is not code optimization)
Building Compilers
Writing Operating Systems

Why do people still study Latin? I think the purpose is not to write Latin or use it to communicate. However, assembly language is still alive.

Lagacy systems 梗有㗎，但依家軟件業，絶大部分寫比PC，Mac，iOS and Android，和 game consoles。呢D唔會理 code efficiency。慢慢鬥 Assembly, 不如快D完成。

但對backend operation, code efficiency依然重要.

好多好似好low end好落後既嘢, 實際上因為無乜新人識或者願意接手, 所以更加吃香 (不過唔係香港會發生既事)

當手機八核CPU，6GB RAM 係好普通的時候，當 GoPro 可以4K video 加 software image stabilization, code efficiency 已經無乜人考慮。Consumer products, consumer software 已经好少好少好少人用。呢個年代仲講 assembly 一係非常 niche application, 或者顯示自己年長而己。

Assembly language，一般firmware engineer/programmer 都懂，而他們多用c,c++language。 好多真係識IT security嘅人都懂assembly language。

學習嘅野，一理通，百理明，we learn how to learn. 一個工程學位一定包括基本數學和學科相關理論。再加上最新嘅技術應用，對就業同將來發展會有幫助。

唔使坦心南韓

Welcome to Multimedia and Wireless Networking Laboratory (MWNL) at Department of Electrical and Computer Engineering and INMC, Seoul National University!

We conduct research on wireless networking, well-balanced between theory and practice by (1) developing new networking protocols/algorithms and (2) evaluating/demonstrating them via analysis, simulation, and system building.

Our research interests include the protocols/algorithms/applications for wireless networking! At this time, we are in particular working on 5G cellular, 4G LTE evolution (including D2D, V2X, LTE-LAA), Wi-Fi/Bluetooth for IoT, aerial acoustic communication, video multicast, spectrum sharing, coexistence at unlicensed bands, energy efficiency, and mobility support.

對住唔係咁認識IT既人, 講太多係無乜用

C點解可以一直咁多人用, 係因為佢係最接近人既邏輯思維方式去編程, 亦可以有效調教程式效能既Programming Language (如直接call interrrupt access HW). 只係如果要用嚟設計UI, 會比較辛苦同抽象.

其實不少科技知識, 根本不會落後, 只有"科技工具", 先會落後

好似N年前, 曾吹嚧ATM網絡(Asynchronous Transfer Mode, 唔係銀行網絡), NC (Network Computing), 今時今日, 咪又係就嚟俾人放去博物館.

近年吹捧既AI (人工智能), SDN (Software Defined Network, 即係一台機器, 可隨OS既功能變成router, switch, firewall.....), 又係舊酒新瓶

似乎你真係對IT，或至少Prigramming有認識。

Assembly現實中除了同HW研究有關，應該唔多人用了，而且佢係CPU depend，用Intel, AMD, RISC已經會有所不同了。

目前大部份人只識用效率低既Visual tools.
