Alimenta ogni corsa!

Sram ha unito l'affidabilità, l'eleganza e le caratteristiche del leggendario misuratore di potenza Quarq e ha abbattuto ancora una volta le barriere all'ingresso. Questa nuova piattaforma del misuratore di potenza è interamente contenuta nel perno DUB per un'integrazione pulita che si adatta a più biciclette che mai. Si tratta di una tecnologia invisibile che aggiunge un peso minimo e ti aiuterà a raggiungere il traguardo più velocemente.

Caratteristiche:

  • L'unità basata sul mandrino DUB-PWR misura la potenza del lato sinistro per calcolare i watt totali.
  • Comprovata affidabilità e precisione Quarq.
  • Il movimento centrale DUB aggiunge durata e semplicità.
  • Batteria: AAA al litio sostituibile di lunga durata (400+ ore).
  • Impermeabilità: IPX7 impermeabile fino a 1 metro per 30 minuti.
  • Lunghezza del braccio della pedivella: 170 mm / 172,5 mm / 175 mm.
  • Peso reale: 359 g.

 

Tecnologia

AXS
AXS è il nuovo sistema di integrazione dei componenti della bicicletta di SRAM che collega i componenti elettronici della bicicletta e il software. L'app SRAM AXS permette ai ciclisti di vedere lo stato della batteria, programmare i componenti, personalizzare i controlli, ottenere promemoria di manutenzione e aggiornare il firmware.

DUB
La relazione tra il perno del movimento centrale e il cuscinetto è il cuore della tecnologia DUB. È dove la rigidità incontra la durata. È stato reso tutto più semplice integrando meglio il rapporto tra corona, pedivella, mandrino e movimento centrale. Questo approccio allo sviluppo di un sistema completo equivale a migliori prestazioni della trasmissione.

DUB-PWR
DUB-PWR prende la misurazione della potenza affidabile e precisa di Quarq e la ospita elegantemente all'interno del mandrino della pedivella DUB per la compatibilità con qualsiasi configurazione di ingranaggio, misurando la potenza sul lato sinistro per calcolare i watt totali. È leggero, invisibile e facile da raggiungere.

There's nothing else out there that's this comprehensive
Format: Hardcover
Unlike my last review, this one I'm happy to write. I'm a game engine programmer, but I don't have a long history with games, and how their engines are typically structured. Every in-house AAA engine will be different of course, and obviously you won't find books (or typically any docs at all really) on the structure of these behemoths, so the best you can hope for is something that tries to give you the high level overview of what to look for - how a tools pipeline is setup, what subsystems to expect, how they interact, etc. This book provides all of that, and so, so much more. I really can't believe how much is packed in this thing. A really nice section on OS fundamentals, extensive coverage of concurrent programming, tools, audio, physics, it's all there (in one way or another). Like most of these kinds of books, you probably don't want to try and read it front to back (although that would be awesome, who has the time for that?) Instead, I've been going to sections on an as-needed basis and picking up just the stuff I need most at that time, and it's been great. I'm at the point in my career where I'm just not buying as many books as I used to, either because they don't deliver on their promises, they only cover the basics, or they just rehash things that have already been covered extensively in other books. This book's definitely got me excited, because it provides a ton of real-world info that's hard to get anywhere else. 100% recommend to anyone new to game engine software development. UPDATE: 6 months later, and this book continues to amaze. After studying every line of code in the section on memory allocators, I've added this feature to my engine and it works great. Same with quaternions. I just keep finding myself reaching for this book! What a great resource, rock solid.

Don't peek at the next page.
Format: Hardcover
Basically, best practices in game engine architecture, citing a wide array of game engines used by a wide array of top game makers. Out of a ~1150 page book: The longest chapter is ~150 pages, on Parallelism and Concurrent Programming. Rendering Engine is ~100 pages Collision and Rigid Body Dynamics is ~100 pages 3D Math for Games is ~50 pages I had hoped for treatments on quaternion camera and for entity component system, but alas, no. What I did get was still crucial. The most illuminating guidance was in Engine Support Systems (~50 pages) which talked about best Memory Management, and in Game Loop and Real-Time Simulation which talks about ideal orders of operations in a highly efficient game loop. The first 400 pages of this book are not exclusive to games. A new programmer that wants to do high performance programming can gain a lot from this before it gets into 'primarily' game topics. My strategy for getting through this whale was to never peek at the next page. I did not read (Character) Animation Systems (~100 pages) or Audio (~100 pages), as I do not need them at this time. You can certainly damage the book if you don't keep in mind its weight, or if you do that maneuver where you forcibly open it against its spine. I did that and the binding popped off the backing. It's all in one piece, and it's easier to read. It's a big tome.

The Bible, if it was good
Format: Hardcover
I’m not kidding when I say the first 350 pages of this book are quite literally an entire computer science degree. In fact, many CS majors would learn more about some of these subjects here than in their classes. I’m incredibly impressed with the thoroughness and depth of this absolute tome, and I’ll be far more impressed if the binding is able to hold on to all 1200 pages for the whole time it takes me to read it.

good quality
Format: Hardcover, Format: Hardcover
Content is top notch as always. My 5-stars go mainly to reflect print quality of the book. Text is nice and clear, binding is done in proper cloth spine binding as you would expect from hardcover edition. Ordered my book on Feb 5th, 2019 and received it on Feb 11th, 2019. The book feels solid not like to fall apart right away. No issues like those reported for "Real-Time Rendering, 4th Edition" or "Physically Based Rendering: From Theory to Implementation 3rd Edition" or "3D Math Primer for Graphics and Game Development, 2nd Edition". This one is a keeper, so sad some other CG books had to go beacuse of the quality "issues".
