TON (The Open Network) 或 TONcoin，前身是 Telegram （通訊軟體）發起的 Telegram Open Network.

Miner 算力挖礦 - PoW

支援 GPU 加速挖礦。

AWS g4ad

AMD EPYC CPU + AMD Radeon Pro V520 GPU. - 較便宜、TON 挖礦效能好、CP 值高。 - ETH (ethash) hashrate 算力很低，不適合雙幣挖礦。

建立 instance 時，請確定選擇了用 Ubuntu 18.04，因為 AWS 只提供給 Ubuntu 18.04 的 GPU 驅動程式。

TON (The Open Network), or TONcoin, former Telegram Open Network founded by the instant messaging app Telegram.

Miner - PoW

We can use GPU for mining.

AWS g4ad

AMD EPYC CPU + AMD Radeon Pro V520 GPU.

• Lower price, better TON mining performance, better C/P value.
• ETH (ethash) hash rate is low, so not for dual mining.

Make sure to use Ubuntu 18.04, as AWS doesn't provide Ubuntu 20.04 drivers.

Upgrading PHP to 7.2 might break your Drupal 7.

Here are some error/warning examples and how to fix them.

Fixing by getting the latest GitHub Pages alias settings and update the records on Cloudflare.

Packaging software might sound scary, but backporting Ubuntu package is actually easy.
When you need some features or bugfix in a newer version of software, which exists in latest Ubuntu release, but need it to be running in your older release of Ubuntu, what you need to do is to port the software from latest Ubuntu to the version you want. And in this HowTo I'll guide you through.

1. Install tools: sudo apt install ubuntu-dev-tools
2. Set developer (YOU) info: export UBUMAIL="Your Name <[email protected]>"
3. Use tool to backport backportpackage -w . the-package-name

One of the projects I work on uses GitLab . We host our codes on GitLab, review codes and commits, and use GitLab CI to do all the CI auto-testing jobs before we merge branches.

Normally mock data for TDD Unit Test shouldn't be a difficult job, but once we need to do something more complicated, like searching relations in a graph database, or doing some Integration Test, it became a mess, no matter we put them in test codes or put them in separated files and load when needed:

• updating hundreds of records in a thousands-rows mock dataset .
• container stats and changes will not be kept across stages and jobs, so in every jobs and stages we need to load them again and again.
• it takes time and resources to load data into database, and we don't want to wait them long.
• wasting resources might cause global warming.

My Drupal 8 site got some problem and I restored it from an old backup.
The problem is, I forgot the password of admin account, and I don't have a working MTA (ex, Postfix Mail Transport Agent) on the server for sending password resetting mail.
The solutions to reset password and unblock the account in database directly.

Hope this HOWTO can save a tree and a kitten.

最近向我尋求顧問諮詢的組織單位中，其中一個再也受不了微軟的天價授權費勒索，打算用 Linux (Ubuntu) 替換掉所有 Windows Server。用 PHP、Java 以及其他跨平台語言撰寫的服務要轉移很容易。但是其中一些系統使用 MicroSoft SQL Server 作為資料庫。
治本的方法是轉移到 MySQL、MariaDB 或其他 OpenSource 資料庫系統，但那需要時間來處理所有 schema 以及 query 的轉換。
另一個方法是在 Docker 中使用 Linux 版微軟 Microsoft SQL Server 作為暫時性的過渡時期解法。

One of the organizations that recently consulted me for advice, no longer willing to be extortion by Microsoft's high licensing fees, and plans to replace all Windows Server with Linux (Ubuntu). No big deal for services written in PHP, Java, and other cross platform languages. But some of the systems use MicroSoft SQL Server as their Database. The permanent cure is to migrate to MySQL, MariaDB, or other OpenSource Databases. But it takes time to translate all schema and queries. The other solution is to use Microsoft SQL Server on Linux in Docker as a temporary workaround.

I was upgrading an old drupal 6 site to drupal 7.
Lots of modules and themes need to be upgraded at the same time. Some are easy, but some not when it comes to dependency issues.
I keep getting Some of the pending updates cannot be applied because their dependencies were not met. error when running Database update. OK I know there's some problems with module, but which module(s)?
