Catalog of Patterns of Distributed Systems
Distributed systems provide a particular challenge to program. They often require us to have multiple copies of data, which need to keep synchronized. Yet we cannot rely on processing nodes working reliably, and network delays can easily lead to inconsistencies. Despite this, many organizations rely on a range of core distributed software handling data storage, messaging, system management, and co

Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O
Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O When talking about high-performance software we probably think of server software (such as nginx) which processes millions requests from thousands clients in parallel. Surely, what makes server software work so fast is high-end CPU running with huge amount of memory and a very fast network link. But even the

本番でTableを1つDeleteしてしまいON DELETE CASCADEでさらに4つTable dataが消えた話 - Qiita
起きた事 本番環境のデータ調査の依頼を受けた。その調査を受ける前に、それとは別で不要データを本番DBから削除する作業をMySQL Workbenchで行っていた。 本番DBで、データ調査を行う際にMySQL WorkbenchでSQLのselectと間違えてdeleteを実行してしまい、Tableを1つ丸ごとDeleteしてしまった。 ON DELETE CASCADEが親テーブルに設定されてしまっていたため、さらに4つのTable dataが芋づる式に消えてしまった。 ON DELETE CASCADEの説明としては、この記事がわかりやすかったです。 https://www.dbonline.jp/mysql/table/index11.html テーブルの構成(テーブル名などは例として挙げていて、実際のものとは多少異なります) 正しい設定 usersテーブルでuserを削除した時に、そ

GitHub - brendoncarroll/webfs: A Filesystem Built On Top of the Web.
WebFS is a filesystem built on top of the web. WebFS started after looking for a way to use IPFS as a Dropbox replacement, and not finding any really solid solutions. I also wanted to be able to fluidly move my data between traditional storage providers like Dropbox, MEGA, or Google Drive while testing the waters of new p2p storage systems, like Swarm or Filecoin.

Why Dns On Blockchain Is The Next Step After Dns Over Https
Last month, the trade association for internet service providers in the U.K. has nominated Mozilla for this year’s award of Internet Villain because Mozilla plans to support DNS-over-HTTPS that would bypass U.K. filtering obligations and parental controls, undermining internet standards in the U.K. At Diode, we think Mozilla’s DNS-over-HTTPS in general is a good move for increasing the privacy of
