When would SQream DB be right for me?
I’ve been a part of SQream DB for over three years, now entering the fourth year.I started out in the core of the product – the SQL parser and compiler written in Haskell. My experience with the product started out in pure amazement at what it can do (I came from mySQL), and has evolved…

SQream DB string cheat-sheet
There is some lack of handy documentation for SQream DB – a fast, GPU based analytics SQL database. I decided to make a few cheat sheets to help out my fellow SQream DB DBAs. Strings Download as PDF – SQream DB Cheat sheet – Strings (164KB) -
Nvidia GTX 1080 vs Nvidia Tesla K40 – Installing a GTX1080 in a Dell R720
At SQream Technologies, we use Nvidia graphics cards in order to perform a lot of the heavy database operations. With SQream DB, we usually recommend using a Tesla K40 or K80 card. While a Tesla K40 is designed to operate inside a server enclosure (it has no onboard fan), standard Nvidia cards like the GTX…

However, our recent influx of new customers requires a little more attention in curating proper error messages. I gathered all of our developers and we did…

Malicious traffic detection using traffic fingerprints and machine learning
Over the past year, we’ve worked on a machine learning project at Ben Gurion University of the Negev. The project attempted to find out if we can identify malicious underlying traffic (viruses, botnets, command and control channels) hiding interspersed in ‘normal’ network traffic, without using advanced heuristics or deep packet inspection – but by using…
