In the fast-paced world of personal development, one woman has continually stood out—Shoshanna Raven. Her influence extends beyond coaching sessions. Her retreats are transformative, and her message of ‘Living Brave’ has resonated deeply with countless individuals. But what makes her leadership so impactful? The answer lies in the voices of those who have walked the path with her—her clients. Rave

An ultra-fast, ultra-compact, crash-proof, key-value, embedded data store Symas LMDB is an extraordinarily fast, memory-efficient database we developed for the OpenLDAP Project. With memory-mapped files, LMDB has the read performance of a pure in-memory database while retaining the persistence of standard disk-based databases. Bottom line, with only 32KB of object code, LMDB may seem tiny. But it’
PBS: Probabilistically Bounded Staleness How eventual is eventual consistency? How consistent is eventual consistency? PBS provides answers to these questions using new techniques and simple modeling. Find out how and play with models in your browser on this page. "All good ideas arrive by chance." Max Ernst Eventually consistent semantics provide almost no guarantees regarding the recency of data
AvocadoDB is an easy to use mostly memory, high performance, open source db with a unique combination of features like support for graph & geo algorithms.We recently started a new open source project – a nosql database called AvocadoDB. Key features include: Schema-free schemata let you combine the space efficiency of MySQL with the performance power of NoSQL Use AvocadoDB as an application server
The relational model of data was proposed in 1970 by Ted Codd5 as the best solution for the DBMS problems of the day—business data processing. Early relational systems included System R2 and Ingres,9 and almost all commercial relational DBMS (RDBMS) implementations today trace their roots to these two systems. Back to Top Key InsightsMany scalable SQL and NoSQL datastores have been introduced over
In April 2020, NoSQL-Database.org joined forces with hostingdata.co.uk. These two websites and the teams responsible for their creation will now work together. The decision was made after the owners recognized that they have a common objective – helping people in the UK (and beyond) understand web hosting and all its intricacies, including NoSQL databases. This list is updated monthly. We’ve teste
SKS rep @repeatedly あ，WAL使ってなかった．しかしどうやって非同期になってんだ？普通にmemcpyとかしてるようにしか見えんが… 2011-05-17 03:22:15
Working with hugedomains.com was a quick and easy process. We got to speak to multiple real people located in Colorado without having to wait on hold! Our only complaint was we felt we had to overpay more than this particular domain was worth, and we weren't able to negotiate it down to a level that we felt was fair. However, payment and delivery were seamless, and within a few hours we had all of
Overview Kyoto Cabinet is a library of routines for managing a database. The database is a simple data file containing records, each is a pair of a key and a value. Every key and value is serial bytes with variable length. Both binary data and character string can be used as a key and a value. Each key must be unique within a database. There is neither concept of data tables nor data types. Record
This document discusses distributed programming and data consistency. It defines consistency as how systems and observers perceive the state of a system over time. Consistency has a time aspect, where expected and unexpected sequences of states can occur. Distributed systems like caching introduce inconsistencies when data is replicated across servers. The CAP theorem states that a distributed sys
ここ2-3年ほど、いわゆる非SQL系データベースがホットな話題になってきています。このムーブメントを総称して「NoSQL (Not-only SQL)」と呼ばれることが多いようです。まるでSQLを否定しているかのような誤解を招きやすい用語ですが、かといってキー・バリュー型データストアや列指向DBを総称できる他の呼び方もないので、このエントリではNoSQLという用語を使うことにします。 OracleやMySQLなどのSQLデータベースが成熟していく一方で、SQLデータベースを特徴づける弱点である柔軟性のなさ、堅牢さと引き換えに犠牲になった更新性能の低さ、スケールアウトの難しさなどから、「何でもかんでもRDB」から「目的に応じた永続化」が模索される流れになってきました。 時を同じくして、キャッシュサーバの世界でも、MemcachedのもつシンプルなAPIの使いやすさが評価される一方、LRUによ
