I didn't realize Rogue Wave still existed, since I haven't heard of anything they've done since their C++ STL implementation that was once popular. Looks like they've been on a bit of an acquisition spree with about one per year since 2009.

This probably won't have a huge effect on PHP since it's much less Zend-dominated than it once was.

I used the Rogue Wave pre-STL C++ libraries.

I developed a poorly-performing NoSQL-like DB library using their BTree, serializer/deserializer, file-interface, and collection library components. Records had a primary index (for storage order), multiple indices, arbitrary binary data payload, arbitrary-sized values in index "columns". It worked reliably but there were file fragmentation issues and delays during "vacuum" operations. This was in 1995 / 1996. I was junior and didn't know enough about system-level concerns, having come from a more computer-graphics / algorithms / math background. The company didn't want to shell out for expensive canned solutions. Our product sold well enough, but I learned a lesson.

Me too, at around the same time. Mine was an object storage backend for desktop applications. It had MFC-style object graph serialisation and, IIRC, simple indexing. It also had similar performance issues to the ones you mention. I recall enjoying working on it.

However primitive it looks now, Tools.h++ was ahead of its time back then. Just having a decent string class (with copy on write) was nice to have.

Yes, haha! Tools.h++

I know of some companies in the financial domain that still use their array based implementations. I thought they were on their way out but they seem to be rather doing well ?

Are there any other products other then the C++ STL implementation + their array library they are known for ?

Rogue Wave owns IMSL, mathematical and statistical libraries for C, Fortran, and other languages.

They own PV-WAVE, a sister language to IDL.

This is great news for the steadily diminishing population of PHP engineers who haven't heard of PHP-FPM+Nginx or PHPStorm

Not sure what you're referring to, are you thinking of HHVM? FPM is part of the standard PHP implementation and uses the Zend engine.

Seems like a bizarre acquisition to me. Where's the overlap in Rogue Wave's libraries and PHP?

There's good people at Rogue Wave though, and I'm sure they'll be good stewards whatever the strategy turns out to be.

I really don`t know who is Rogue Wave. But I wish them good luck and hopes that they heps Zend to achieve new goals, for the sake of php.

Glad Zend open sourced their PHP opcache before this, well that and their PHP7 work too.
