Overview:

The Holley GM LS7 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS7 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!  The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.  Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations  EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.  Cast aluminum construction.  Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

Good Information, But Poorly Made
Format: Paperback
Educational and I was getting it to assist with getting my PMP. However my only criticisms about the book is that there is a ton of empty space on the pages. I think there would’ve been a better more environmentally friendly way to compact the information in the book. In addition it is very hard to read the book when the spine is constantly spreading apart. I’m afraid that the book pages are going to rip off one time or another. They haven’t yet but it is a concern.

Agile Practice Guide
Format: Paperback
Una muy buena compra para tener como guia repaso de los conceptos mas importantes de las metodologías agiles, y que variables tener en cuenta a la hora de encarar un proyecto y definir con que metodología se gestionará el mismo. En un mundo en donde todos quieren IMPONER metodologías que todavía no entienden muy bien pero estan de moda, es una muy buena herramienta para entender cuando es valido hablar de metodologías agiles, de cuando hablamos de metodologías hibridas, o inclusive discutir si no es un approach mas eficiente el de ejecutar una metodología waterfall o lineal. 100% recomendado.

Excellent Introduction to SQL
Format: Paperback
I am compelled to share my overwhelmingly positive experience with the SQL Quickstart Giude which has proven to be an exceptional resource for anyone wanting to delve into the world of SQL coding. First and foremost, the book is written in an extremely accessible manner, deftly simplifying complex concepts into digestible portions for beginners, yet providing deeper insights for seasoned developers. It transcends the barrier of technical jargon, presenting information in an intuitive, reader-friendly style. However, the true selling point of this book, which separates it from the plethora of SQL resources available in the market, is the ingenious inclusion of its online resources. This addition enhances the book's value immeasurably, allowing the reader to step beyond the theoretical and put their knowledge into practice immediately. The online resources that accompany the book provide a unique learning ecosystem, an ideal blend of theory and practice. They offer a plethora of well-organized and insightful coding examples for each chapter, which are also available for download. This allows the readers not only to work along as they learn but also to experiment and implement their own iterations of the code. This hands-on approach cements the concepts learned in a way that theoretical learning alone cannot. Moreover, these downloads enable offline access, which ensures that you can learn at your convenience, a feature that not many SQL books offer. This aspect of anytime, anywhere learning is crucial in our current fast-paced world. Furthermore, the author provides ample exercises to test your understanding, which are then complemented by detailed solutions on the online platform. This real-time feedback is instrumental in understanding one's progress and identifying areas for improvement, which paves the way for a confident and competent SQL programmer. In conclusion, the "SQL Quickstart Guide" with its companion online resources has proven to be an unbeatable combination for learning SQL. It has created a learning experience that is seamless, engaging, and, most importantly, effective. It is a rare gem in a field often dominated by dense, inaccessible texts and I would highly recommend it to anyone wishing to embark or advance their journey in SQL programming.
