RedGate SQL Server Concurrency: Locking, Blocking and Row Versioning - Book Review

Although this began as a usual book review, it quickly grew into an all-encompassing article as a result of the additional and extended commentary

While concurrency is always covered as part of a book on SQL Server, this title is totally dedicated to it. Exaggerated one might say; quite the opposite and with good reason I would say. It aims to raise awareness of this frequently underrated subject whose incomprehension can result in massive performance complications.

The problem lies in that no matter how well designed your application, database, or SQL queries are, all working harmonically in isolation, going multi-user without putting considerable effort into understanding concurrency (and how your specific DBMS goes about it), will sooner or later lead your edifice into collapsing, shaken by performance degradation, unacceptable waiting time or even corrupted data state.
So this is where this slim guide comes in, to properly educate anyone working with the RDBMS in keeping out of trouble, building a greatly performing multi-user application and being ready to troubleshoot when the need arises.

Book Review : How To Create Pragmatic, Lightweight Languages

At last, a guide that makes creating a language with its associated baggage of lexers, parsers and compilers, accessible to mere mortals, rather to a group of a few hardcore eclectics as it stood until now.

The first thing that catches the eye, is the subtitle:

The unix philosophy applied to language design, for GPLs and DSLs"
What is meant by "unix philosophy" ?. It's taking simple, high quality components and combining them together in smart ways to obtain a complex result; the exact approach the book adopts.
I'm getting ahead here, but a first sample of this philosophy becomes apparent at the beginnings of Chapter 5 where the Parser treats and calls the Lexer like  unix's pipes as in lexer|parser. Until the end of the book, this pipeline is going to become larger, like a chain, due to the amount of components that end up interacting together.

The book opens by putting things into perspective in Chapter 1: Motivation: why do you want to build lan…

Deep Angel-The AI of Future Media Manipulation

Undeniably, we live in the era of media manipulation. Such powerful and accessible tools exist today that nearly everyone can do it. Now add to this collection Deep Angel, an artificial intelligence that can erase objects from photographs and videos.

I was notified of Deep Angel around the time I was watching Kill Switch, a futuristic and dystopic movie about our Earth getting cloned in order to suck the resources of the cloned planet, something that would sustain our world's energy needs for at least another millennium. To cut a long story short... full article on

SAP's Creating Trustworthy and Ethical Artificial Intelligence

With the ink hardly dry on the pages of the EU Ethical AI Guidelines manifest, a free online course exploring the issues they raise is already in prospect on the openSAP platform. Run by members of the very same group, the European Union’s High-Level Expert Group on Artificial Intelligence, who wrote the guidelines and in cooperation with SAP's online education platform, a course with the titleCreating Trustworthy and Ethical Artificial Intelligence has been made accessible to anyone with an interest on AI or ML:
