Immutability, MVCC, and Garbage Collection
Immutability, MVCC, and Garbage Collection Published Dec 28, 2013 by Baron Schwartz in Databases, Best Of at https://www.xaprb.com/blog/2013/12/28/immutability-mvcc-and-garbage-collection/ Not long ago I attended a talk about Datomic, which focused a lot on database immutability and its benefits. I hope to illustrate why many database designs are much more complicated than Datomic and its ilk. Alt
NoSQL Data Modeling Techniques
NoSQL databases are often compared by various non-functional criteria, such as scalability, performance, and consistency. This aspect of NoSQL is well-studied both in practice and theory because specific non-functional properties are often the main justification for NoSQL usage and fundamental results on distributed systems like the CAP theorem apply well to NoSQL systems. At the same time, NoSQL
10 things never to do with a relational database
10 things never to do with a relational database The data explosion demands new solutions, yet the hoary old RDBMS still rules. Here's where you really shouldn't use it I am a NoSQLer and a big data guy. That's a nice coincidence, because as you may have heard, data growth is out of control. Old habits die hard. The relational DBMS still reigns supreme. But even if you're a dyed-in-the-wool, Oracl
IndexedDB Status Report and Demo - davidflanagan.com
I've been trying to create an IndexedDB example for the next edition of my JavaScript book. IndexedDB is a promising API, but it turns out to be just barely useable right now. I'm using Firefox 4b10 and Chrome 10.0.642. Here are some things I've found out. Maybe they'll help someone! Both Mozilla and Chrome prefix the global indexedDB object. Use mozIndexedDB or webkitIndexedDB. Prior to FF4b9, a

Programming Languages: What tool is right for which job?
We all talk about using the right tool for the job in the context of programming items. But which job? And what's the right tool for it? I want your help in determining the answer for this. Getting started First I need you to tell me which programming languages you know: Ada Agda APL Assembler AWK C C# C++ Clojure Cobol Common Lisp Coq D Delphi Eiffel ELisp Erlang F# Factor Forth Fortran Go Groovy
What the heck are you actually using NoSQL for? - High Scalability -
It's a truism that we should choose the right tool for the job. Everyone says that. And who can disagree? The problem is this is not helpful advice without being able to answer more specific questions like: What jobs are the tools good at? Will they work on jobs like mine? Is it worth the risk to try something new when all my people know something else and we have a deadline to meet? How can I mak
