I just made a docker dev env which pre-setup essential tools for Solana development.

included:

Rust v1.68
Solana-cli v1.14.17
Node v18.16.0, with NPM/YARN
Anchor v0.27.0

「同學」對學習的幫助

Airic Yu — Mon, 10 Apr 2023 07:29:18 +0000

近來有個感覺是,
關於學習，其實學伴﹑同學對學習也是有莫大益處。

老師的教學能力﹑學生自身的學習能力，是最直接影響知識傳遞效益。
但其實「同學」之間的互動，對學習也是有不少益處。

同學互動，能提升學習氛圍(講白話就是「大家一齊去經歷學一樣野會開心D」)。
學生之間一知半解，但彼此一知半解也是一種共同理解，對談討論﹑無知發問，有時會激發到一些思考，更易消化。

這就令我發覺,
作為成年人去學一樣野，不一定就是自己上網google﹑youtube，孤狼作戰地學習。
其實認真去學一件事的話，最好是加入相關社群，在相關領域中去找同路人一齊學習。

Typescript project template (NodeJS)

Airic Yu — Sun, 09 Apr 2023 11:03:01 +0000

TLDR
This is a minimum setup of Typescript project template (NodeJS).

Github repo:
https://github.com/airicyu/typescript-project-template

I faced some setup issues some time ago.
The typescript stuff X nodejs module type bla bla bla....
I also spent some time to find correct setup to debug with typescript that looks fit.
All I want is sth that "It just works" and let me start coding.

After all, recently I find this template looks good and I used in several projects as starter template.
So I also want to share it with other developers, especially those who are new to learn NodeJS/Typescript.

關於throughput

Airic Yu — Sat, 08 Apr 2023 07:49:42 +0000

講processing性能有時要留意一樣野。

例子:
"10個女人"用10個月可以生產到10個BB。
throughput(吞吐量) = 平均每個月生產到1個BB
但係我地如果想生產一個BB，然後跟據吞吐量，我地俾一個月時間去生產一個BB，件事係唔work。
實際上單個BB，係需要用10個月生產出來。
吞吐量係包含埋平行處理能力。

當去了解blockchain性能,
除左講求throughput，有幾多transaction per second,
仲需要去了解，實際上單個transaction，幾耐出到個block (confirm = 1)?
實際上去到finalize (confirm = N), 又係要幾耐?

以eth為例,
throughput大約2x-5x trx/s。
佢大約12秒出一個block。
如果要12個confirm，就大約要2-3分鐘，先可以好大機會肯定個transaction係已經完全成功左。

Solana client sample - Do 100 times wallet transfer

Airic Yu — Sat, 08 Apr 2023 06:36:05 +0000

Recently I am learning Solana blockchain. So I will write some sample code or sharing posts during my learning journey.

This time, I would like to share some sample client code for doing 100 times wallet transfer.

Github repo:
https://github.com/airicyu/solana-sample-client-wallet-transfer

As you can see, doing 100 transfer operation and get a confirm is just taking ~900ms.
In terms of interactions we do with BLOCKCHAIN nowadays. Performing a series of 100 operation get confirm(Not finalized yet though) in 900ms is very amazing.

This is rather crazy speed, and that's why I am diving in to learn Solana now.

I wanna find a blog for recording or sharing my dev stuffs.
Let me try to use dev.to then.
