Couchbase vs RavenDB Performance at Rakuten Kobo Whitepaper

Rambled Thoughts

time to read 1 min | 182 words

I am usually a big believer in separation of concerns for posts, but this a collections of interesting things that have crossed my path recently, which I don't have the time/energy to do full posts about.

Andrew Davey is doing some cool things with Boo's new meta methods and Rhino Mocks.
David Hayden has a cautionary tale about the dangers of unmaintainable code generation strategies
Rob Walling writes about demotions to management and why it happens. I am striving hard to not get into that position by being slightly off from the politically correct route. I have done my stints in managing people, I can do it, maybe even be good at it, but I like to code better than herding cats.
Linchi Shea has a post about the performance implications of not using the schema qualifier. Apparently it can range from 5% to over 25% difference in performance. Makes me happy that I am using NHibernate, 5% improvement is just a "hibernate.default_schema" away :-)

Dmitry, Yes, but this is _known_ to be a 64 bits system - since we are allocating 3GB (not possible in 64 bits). Note t...

That's why it is a good idea to compare the return value of `write` to the buffer size. "size_t" can be 32-bit on some system...

There's a reason we miss `write_exact` and `read_exact` from the standard library. In fact, I am surprised the chunk is actua...

kpvleeuwen, I agree, unfortunately I don't have anyone to ask off the top of my head. Thanks, I fixed the headers.

It could be interesting to reach out to storage firmware developers and ask what write patterns they think would be useful ex...
