Dgraph 在推銷自家發展出來的 Badger：「Introducing Badger: A fast key-value store written natively in Go」。
標靶是 RocksDB，號稱比 RocksDB 快好幾倍：
Based on benchmarks, Badger is at least 3.5x faster than RocksDB when doing random reads. For value sizes between 128B to 16KB, data loading is 0.86x - 14x faster compared to RocksDB, with Badger gaining significant ground as value size increases. On the flip side, Badger is currently slower for range key-value iteration, but that has a lot of room for optimization.
不過我覺得有些重要的功能在 Badger 不提供，這比起來有種橘子比蘋果的感覺... 像是 RocksDB 提供了 Transaction，而 Badger 則是直接講明他們不打算支援 Transaction：
Keep it simple, stupid. No support for transactions, versioning or snapshots -- anything that can be done outside of the store should be done outside.
EFF 推出新的延伸套件 (有 Firefox 與 Google Chrome 版)，透過演算法阻擋嘗試追蹤你的單位：「Privacy Badger」。
At a more technical level, Privacy Badger keeps note of the "third party" domains that embed images, scripts and advertising in the pages you visit. If a third party server appears to be tracking you without permission, by using uniquely identifying cookies to collect a record of the pages you visit across multiple sites, Privacy Badger will automatically disallow content from that third party tracker. In some cases a third-party domain provides some important aspect of a page's functionality, such as embedded maps, images, or fonts. In those cases Privacy Badger will allow connections to the third party but will screen out its tracking cookies.
技術上的作法是分析 third party domain 的行為，用演算法阻擋可能的追蹤。與 Ghostery 這類工具使用人力建立清單的方法不太一樣。
