Overview:

Our engineers designed the line of Hi-Tek differential covers to not only look good but address a number of weaknesses of the factory stamped steel covers. First, they started by constructing the covers of thick A356.0-T6 aluminum, which dissipates heat much faster than the factory steel unit keeping the fluid temperature lower under high-stress loads vs. a steel cover. Then for added durability, we added a reinforced center bar for extra strength along with load bolts to help prevent bearing cap deflection under severe loads. The internal shape of the cover retains the smooth round back internally to help keep the fluid flow going over the ring gear to properly lubricate and cool the bearings and ring & pinion gears. Additional features include a magnetic drain plug for catching ferrous metal particles, MIL-Spec (MIL-A-8625) black anodized finish, machined B&M logo, and all necessary hardware and easy to follow detailed instructions for a quick and simple installation you can do at home. Note: Gasket not included.

Features:

  • Load Bolts Provide Additional Support to Bearing Caps
  • Magnetic Drain Plug for Easy Servicing
  • A356.0-T6 Aluminum Construction
  • Additional .5-quart Fluid Capacity
  • MIL-Spec Black Anodized Finish
  • Over 65 Years of B&M Quality
  • Lifetime Limited Warranty
  • Machined B&M Logo

A data engineering journey from basic to advance topics
Format: Kindle
Is the third time that I read this book. One of the most valuable aspects is the fact that depending of your data engineering mature, you'll always find a new aspect or ideas to put in practice. Hope the second version come soon!

Lottery Book
Format: Paperback
This book contains a lot of opinions without facts. Some are true, some are not. But its a lottery, you cold pick a gold text or a text that is full of buzzwords, without any meaning, fact and useless in real life.

Glad I bought this used
Format: Paperback
It’s packed with buzzwords and adjectives, offering plenty of in-vacuum advice and self-promotional ‘hire-me’ vibes. There’s some real insight here, but it’s buried under a lot of noise.

Not useful
Format: Paperback
This book has a few pieces of good advice, but its buried under mountains of weird and amateur level musings. Example: Paul Singman advocates for eliminating ETL entirely. How? Just reprogram the applications to which you may or may not have the source code to handle your data processing. He calls Intention Data Transfer 🥴 Thanks for the advice Paul, I'll get right on that.

Good starting point. But can't find the code.
Format: Kindle
Reading chapter 3. It was so far so good, but can't find the code in the repo. "All the related code can be found in the repository under project/hooks-notification." And in the repo I see no project folder. Please help!
