Jessi Combs Sets New Women's 4-Wheel Land Speed Record

I recently got to travel once again to the beautiful Alvord Desert in southeast Oregon to join the North American Eagle team as they continued their assault on the world land speed record. One of the goals for this year's trip was for new co-driver Jessi Combs to attempt to break a pair of long-standing records, the 308 mph mark set at Bonneville in 1965 by Lee Breedlove, wife of then world record holder Craig Breedlove; and the 512 mph record set at Alvord in 1976 by Kitty O'Neal driving the rocket-powered "SMI Motivator."
After just two test runs, on Tuesday, October 8, Jessi broke Breedlove's record, with a two-way average speed of 344.002 mph through the measured mile.
The next day, Jessi climbed back into the NAE vehicle and made two more runs. This time, she went to full afterburner on both runs. With her parents, sister, and "The List" co-host Patrick McIntyre watching, Jessi reached a top speed of 440.709 mph, pushing her two-way average to set a new record of 392.954 mph and making Jessi Combs the fastest woman on four-wheels.
I have created a video showcasing the second of her two October 9 runs, which I posted to YouTube on Friday.
There are also a lot more of my photos on Flickr.
For those curious about the two women's records, Lee Breedlove set her 308 mph mark in her husband's "Spirit of America Sonic 1" jet-powered car, driving on the salt flats at Bonneville. Since Sonic 1 had four wheels, it is considered a "car" and therefore comes under the rules set by the FIA. The vehicle that Kitty O'Neal drove in 1976 had just three wheels and is therefore considered a "motorcycle" and comes under rules set by the FIM.
Also, since it was powered by a hydrogen peroxide rocket engine, Motivator reached its top speed much faster than a jet-powered vehicle, enabling Kitty to go more than 512 mph on the relatively short Alvord Desert. The North American Eagle team hopes to either "coax" a few more usable miles of smooth desert out of the dry lake bed at Alvord or else find another location so that next year Jessi can beat O'Neal's record, making her undisputedly the world's fastest woman. And NAE owner and co-driver Ed Shadle hopes to break the current world land speed record of 763.1 mph, set in 1997 by Andy Green driving the "Thrust SSC."
Since I am at work on a book about the land speed record, I plan to be on-hand when this occurs.

Also, if you would like to learn more about the North American Eagle, Jessi Combs, and the beautiful Alvord Ranch (where the team was graciously hosted by Paul and Toni Davis) check out the following links:

HP Expands its Z Workstation Portfolio

While most people were waiting today for Apple to make official what most people already assumed was coming, I was patiently waiting to be able to write about some really cool new stuff that I learned about last week but couldn't write about until today.

Last week, I spent a day in the Big Apple at an HP press and analyst event at which the company unveiled a number of new workstations and display products, including the world's first workstation ultrabook, the HP ZBook 14.
The new HP ZBook 14

Unlike other ultrabook computers, the new HP ZBook 14 is a true mobile workstation complete with an AMD FirePro M4100 discrete graphics card with 1GB of dedicated GDDR5 memory. HP will be offering a choice of Intel Core i5 and Core i7 processors. One of the really cool features is that the system automatically switches from the integrated Intel HD Graphics 4400 to the more powerful AMD GPU when needed. Since it's an ultrabook, it comes with a 10-point multi-touch screen. But since it's also an HP workstation, it's ISV certified and comes with HP tools including HP Performance Advisor and HP Remote Graphics Software. It may just be the perfect portable for engineering professionals on the go.

The company also announced two other new mobile workstations, the HP ZBook 15 and ZBook 17. These mark the latest iteration of the company's mobile workstation line, with a name change to clearly identify them as members of the HP Z-workstation family (as opposed to the older EliteBook moniker). The new ZBook 15 will include an option for a super-high-resolution QDH+ 3200x1800 display. Both the 15 and 17 feature a Thunderbolt port as well as optional DreamColor Display panels.
The entire new HP ZBook mobile workstation family
The new ZBook mobile workstations feature 4th Generation Intel Haswell dual- and quad-core processors and next generation technologies from NVIDIA and AMD, including the newly announced Keplar-based professional graphics from NVIDIA. And all three ZBook mobile workstations feature innovative new tool-free chassis for easy upgrades and serviceability.

HP also unveiled updates to the Z420, Z620, and Z820 workstations to include the latest Intel Xeon E5-1600v2 and E5-2600v2 "Ivy Bridge" families of processors as well as memory running 16% faster and 2nd generation Thunderbolt ports for data transfer speeds 4 times faster than USB 3.0.

The new HP Z  workstation family and new Z27i and Z30i IPS displays
Lastly, HP added to its line of professional displays, announcing the new HP Z27i and Z30i displays, which incorporate IPS Gen 2 panels that deliver 100% of the Adobe RGB color space while offering power savings of up to 37% compared to HP's first generation IPS displays.

The HP ZBook 15 and 17 are already available, with the ZBook 14 scheduled to be released in October. The updated Z420, Z620, and Z820 workstations as well as the new displays will also become available in October. I hope to be able to review all of the new workstations and displays as soon as I can get my hands on them, so stay tuned.

File Tabs in AutoCAD 2014

One of the coolest new features in AutoCAD 2014 are the new File Tabs. Located across the drawing area (just below the ribbon), the new File Tabs provide a fast and visual way to switch between open drawings or to create new ones.

When you first start the program, you will see a file tab across the top of the drawing area. With just a single drawing open, you see just one file tab, which corresponds to that drawing. But as you open additional drawings, you will see additional file tabs, one for each open drawing.

File tabs are just one of the new features included in my new iBook, AutoCAD 2014 New Features and Enhancements – Revealed!, published by 4D Technologies/CADLearning. I've uploaded the entire lesson video on File Tabs to YouTube so that you can see for yourself how File Tabs can make it much easier to work in AutoCAD, particularly if you have multiple drawing files open.

If you have an iPad, you can actually download the entire iBook for FREE from the Apple iBookstore. That's right, 4D Technologies/CADLearning has decided to make my new iBook AutoCAD 2014 New Features and Enhancements – Revealed! free this year. So, grab your iPad, open up the iBooks app, and hop on over to the iBookstore. As of today, this is the only iBook available for AutoCAD 2014. So just search for "AutoCAD 2014".
Now that AutoCAD 2014 is shipping, I can finally update my blog with news, tips, and tricks about AutoCAD and some of the other new software from Autodesk (including the new Autodesk ReCap software). So check back.

Rendering in AutoCAD: Ralph Got It Wrong

Judging from Ralph Grabowski's response to an email I sent him yesterday, I don't think he has any intention of publishing my response to an article in this week's edition of his Upfront Ezine. So I'll share my response here.

I have a great deal of respect for Ralph. He is usually quite thorough and calls it as he sees it. But this week, he simply got it wrong.

In this week's lead article, Ralph claimed to have done a head-to-head comparison of AutoCAD's built-in rendering command with Autodesk's new cloud-based rendering service and concluded that the Autodesk 360 rendering was much slower than built-in local rendering. (You can read Ralph's article at

After reading Ralph's article, I wrote the following email:

I really must take issue with the methodology you used in comparing AutoCAD's built-in rendering command with the new cloud-based rendering. A rendering that takes only 4 seconds on your local machine is hardly a valid test.

As you know, I have been testing computers and graphics cards and writing about AutoCAD about as long as you have. My reviews are regularly published in Desktop Engineering magazine, and I have taught numerous classes about rendering at Autodesk University. I also recently added more that 3 dozen lessons on rendering, both local and cloud-based, to the CADLearning series ofvideo-based tutorials for 4D Technologies' AutoCAD 2013 course.

As part of my reviews for Desktop Engineering, I perform a rendering test using a drawing I obtained from Heidi Hewett at Autodesk. Although the drawing itself is relatively simple, it includes numerous materials and multiple light sources, all of which result in much longer rendering times. On a relatively fast dual-core workstation, it is not unreasonable for the rendering to take up to 5 minutes, whereas on a system equipped with two 8-core CPUs with hyper threading enabled, the rendering might be completed in less than a minute. In addition to the number of materials and light sources, the resolution of the rendered image as well as the render quality will also impact the overall rendering time.

Again, this is for a relatively simple model. It would not be unreasonable for a highly detailed model with multiple light sources, all casting shadows, to take 30 minutes or more even on a very fast system with multiple CPUs. While I have not performed any benchmark tests yet comparing local rendering of such a model to Autodesk's online rendering service, I would expect the online service to be considerably faster.

While you do make some mention of the fact that it does take some time to initially transmit the model to the Autodesk 360 service (and you experienced some problems in doing so), it is also worth noting that the online service can render multiple scenes from the same model, whereas to do this on a local system, you would need to render each scene individually. Furthermore, when you render locally, you cannot do anything else in AutoCAD while the rendering is being computed, whereas when you use the online rendering service, you can go back to work in AutoCAD as soon as the online render request has been processed.

I also suspect that most people who use the Autodesk 360 service log in when they first start AutoCAD. They would therefore already be connected when they clicked the Render Online button and therefore would not experience the same delays as you. 

From the image you supplied, I can see that you rendered the model at a resolution of 640x480 using the Medium render preset, settings that are hardly representative of real-world situations. In my tests, I typically render at a resolution of 1280x1024 using the Presentation Quality preset. It's also apparent from the lack of shadows and materials, that you likely rendered using the default lighting mode and that the Oil Module drawing contained no materials.

I suggest that you come up with a more realistic test before you start publishing results that are purported to be representative of real-world results or typical user experiences.
And what was Ralph's reply to my email?

"I clearly laid out the specifications for the benchmarking so that readers could take it at face value. Thanks for your input!"

That's hardly a useful response and I think it does his readers a disservice.

Come on, Ralph. You got it wrong.

AU Opening Keynote

AU kicked off this morning with one of the best keynotes in recent memory. After an intro by Jeff Kowalski, in which he outline 5 disruptive trends, a series of Autodesk customers, starting with a young engineer that has helped build a new lunar lander, came to the stage and delivered truly moving presentations.

They were followed by Autodesk President and CEO Carl Bass, who continued the theme of disruptive technology and explained in broad strokes how Autodesk is taking advantage of those trends.
I shot video of most of the keynote and will be posting portions of it later this week. So stay tuned.

Now it's time for me to finish prepping for the first of my two presentations this afternoon.

Tech Day at Infineon Raceway

Today was an absolutely incredible day here at Infineon Raceway. The IZOD Indy Car Series organized a Technology Day for writers.


After arriving at the track and shooting photos of the Indy Lites practice, we met at the Media Center and were assigned to one of the team's pits for the morning IndyCar practice. This meant that we were sort of captive in the pits rather than being out around the track taking photos, but we got a first hand look at what goes on as the teams work to make final preparations to their cars before the afternoon qualifying session.


After the practice session, we had lunch in the Honda Hospitality tent, hosted by Erik Berkman, President of Honda Performance Development. I've got lots of notes from our lunch meeting, many of which will be included in my forthcoming article.


Then we were driven up the hill to the Versus TV Compound, where Robby Green, VP and General Manager took us through the many tractor trailers that house the various television production facilities, including one trailer containing cameramen operating the numerous remote controlled cameras scattered around the racetrack, and the main control room where the director and producers control the on-air broadcast.


Then we went back down to pit row where we were met by Bryan Herta, former IndyCar Series driver and owner of Bryan Herta Motorsports. We each received Motorola headsets so we could hear all of the race team communications and also ask questions.


Then we met with Jack Arute, the primary on-air commentator for Versus' coverage of IndyCar racing.


Next, we went to the pits of deFerran/Dragon Motorsports, where we met with Eric Zeto, the team's race engineer (who I also interviewed yesterday for my article) and Raphael Matos, driver of the #2 HP deFerran Dragon entry. They explained how the team collects and analyzes telemetry throughout the race.


We then had a bit of a break, so I went back trackside to take photos of the Historic Grand Prix cars during their final practice session.


To round out the day, we were driven up to the IZOD IndyCar Series Paddock Club, where we met with Gil deFerran, 2003 Indy 500 winner and owner of deFerran/Dragon Motorsports, and Tony Cotman, the project manager of the 2012 IndyCar. We also met with Matt Ellis, the manager of Infineon Raceway.


It was an incredible day.

I've also got a bunch of videos that I shot throughout the day that I'll be uploading later once I can edit them down. So check back again later next week.
