It’s my understanding of the paper Replicated Data Consistency Explained Through Baseball . As the distributed system architecture has been widely used in cloud computing during recent years, it brings different needs for ensuring data consistency among the nodes in different conditions. Ideally, the distributed databases are better-off to be possessing the same content at the same time, as if they were a single node. https://dccxi.com/me/ Wed, 23 Oct 2019 02:19:09 -0700 https://dccxi.com/me/ My name is Tong Wu, a Software Engineer living in Bay Area, CA. If you are curious, this website is where I sometimes post my thoughts or ideas that I would like to share publicly. My posts could be found in this page . Instead of pasting my résumé here, I would like to list the things that I like/enjoy, in lexicographical order, so that you can freely compose my portrait in your head. https://dccxi.com/posts/album-artwork-missing-catalina/ Sun, 15 Sep 2019 01:14:03 -0700 https://dccxi.com/posts/album-artwork-missing-catalina/ Just delete the three sqlite database files inside ~/Library/Containers/com.apple.AMPArtworkAgent/Data/Documents/ (so that Music.app will rebuilt the artwork indexes database for you) and you are good to go. Maybe not, because before that, I also copied everything inside ~/Library/Containers/com.apple.AMPArtworkAgent/Data/Documents/artwork/ from the old machine to the new one. The sqlite database files are presumably responsible for maintaining the index between the artwork image files and the music files. Deleting them seems to be the only way I know to trigger the update after the manual import. https://dccxi.com/posts/on-contrarious-opinions/ Sun, 11 Aug 2019 17:48:33 -0700 https://dccxi.com/posts/on-contrarious-opinions/ This morning, I was reading the comments of the apology letter posted by Versace to kill some time before lunch. I didn’t read all of them obviously, but only the several dozens on the top at the time. It’s actually not surprising to notice that only very a few of them are focusing on the facts while the majority of them were just solely expressing their emotions. In case you missed out what happened in the last a few days, Versace was found mistakenly listed Hong Kong as well as Macau on a T-shirt as an independent sovereignty instead of a special administrative region of China, which is regarded as inappropriate considering nowadays international situation. https://dccxi.com/posts/crontab-not-working-catalina/ Tue, 06 Aug 2019 15:23:07 -0700 https://dccxi.com/posts/crontab-not-working-catalina/ It turns out to be a permission issue brought by the newly introduced security features, thus it’s not a “bUG”. To solve it, just add your cron location (in most cases /usr/sbin/cron) to the Full Disk Access lists located at System Preferences.app -> Security & Privacy -> Privacy -> Full Disk Access. “Click the lock to make changes” and “+” to navigate to your cron location. No idea how to navigate to /usr/sbin/cron in the file locator? https://dccxi.com/projects/ Sat, 02 Mar 2019 22:03:39 -0800 https://dccxi.com/projects/ The Evolution of Trust (zh-CN) - Link - GitHub Pin - Yet Another Shuangpin Learning Practice Tool - 🚧 - (not yet published) https://dccxi.com/posts/shortcuts-for-texts/ Sat, 02 Mar 2019 21:39:25 -0800 https://dccxi.com/posts/shortcuts-for-texts/ Handy shortcuts can boost up your productivity by a whole level. I have quite a few of those who empowered me to process texts more efficiently. Most of them are Emacs shortcuts that’s natively supported on Mac. Here is a list of the keybindings I use. Action Keybinding (may be custom) Alternative Keys (same or similar) Move to end of the line control + e end Move to beginning of the line control + a home Delete control + d del Backspace control + h bs Left (back) control + b left Right (forward) control + f right Up (previous) control + p up Down (next) control + n down Delete the rest of the line control + k N/A Remove previous word control + w opt + bs Remove next word control + q opt + del Except for the last one, the keybindings mentioned above were natively supported on macOS.
