American Le Mans at Laguna Seca

Saturday’s ALMS 6-hour endurance race at Monterey’s famous Laguna Secs was fantastic. The GT class was the most closely contested race I’ve seen in a long time, where the lead changed between the last turn and and the start finish, right in front of the main grandstands! Talk about excitement!

Watching, and photographing racing at night was a first for me. A learning experience, and despite this being my first attempt, I’m still happy with some of the images I was able to capture. Most of that I need to attribute to Canon’s fantastic 200mm f2.8 L glass (which I obtained from the L.A. Times a few years back).

So.. without further yammering, here are just a few of the shots that I’ve processed so far, that I like. Keep in mind that Word Press re-compresses the images so you lose clarity… when I get unlazy enough to replace Word Press with a better CRM (when.. maybe never…) this sort of thing will not be such an irritation to me.

In the mean time, it is what it is, and these are the results:

American Le Mans – a few shots from qualifying

I shot over 500 photos yesterday at ALMS qualifying and practice. Here are few of those shots:

One hot car!

This happened early in the first qualifying session. The British, known for finding ways to make things leak, make the Jaguar, which dumped most of it’s oil on the track in the first turn:

Important Browser Security Updates – CA revocation for DigiNotar

Over that last couple of days, most (hopefully all) of the Web clients (browsers) are being updated to revoke the CA (Certificat Authority) for DigiNotar. It’s important that you perform this update.

The reason is simple. They were hacked last week, and several bogus CERTs (SSL private/public key generated certificates used in secure HTTP communications) were issued for some very high profile websites.

You can read the gory geeky details on a recent Slashdot thread [ HERE ]. Additional information about the CA revocation can be read [ HERE ].

If you hadn’t already manually deleted the CA from your mail and web browsing applications, be sure to apply this update. If you have not been automatically notified of an update (SeaMonkey, Firefox and Thunderbird have all updated in the last 72 hours) I recommend you head to the home website of your favorite browser and see if a security update is available.

If you are still reading, you must be asking yourself, “Why is this important?”. It’s quite simple really (and actually rather complex, but I’ll try not to baffle with technobabble).

Hopefully, any time you communicate with a website that uses any type of password, you are ensuring you are communicating using SSL (Secure Socket Layer), which applies a certain degree of security by encrypting your traffic. The mechanics of this required that the website you are communicating with has a valid SSL Certificate issues for, and properly installed on their website.

Now, anyone can create their own SSL certificate by running a couple of X509 / keygen commands, and with a few lines of coded added to their web-browser, get it installed. Sounds simple enough still, right? The problem with that is, unless there is a centralized repository of people trusted to make these certificates, *anyone* could create a certificate for say.. BankofAmerica.com install it on *their* webserver, and apply some other social engineering techniques to fool you into thinking you are securely communicating with the bank, when in fact you are sending your data to, or even through (also known as a Man-in-the-Middle attack) some third party. With a few other hacks, they might even take over full DNS control of the BankofAmerica.com domain (this happened to UPS.COM just this past weekend, in case you wonder how that can happen). Bottom line, you want to know for CERTAIN that the site you are communicating with has a good, valid CERT issued by a reputable CERT issuing authority, not just some no-name criminal somewhere in Eastern Europe.

This trust is based on vetted, trusted, Certificate Authorities. If you want to look at he list of these trusted CA’s on your browser, it’s going to look at little mind boggling. Anyone on that list that issues a CERT for a website is automatically trusted by your software (and everyone else’s software too, unless you manually remove / revoke CA’s yourself, like I’ve done), so if anyone in that list has a compromised SSL signing system, then any CERT generated by that authority can no longer be trusted. This is the case with DigiNotar.

People far better at writing than I explain this further here: DigiNotar certificate authority breach: Why it matters [ link ]. I recommend you read it and learn a little something about how the web really works. I also suggest that if you are in business and depend on your website, you get some PROTECTION for your DNS with a product like this!: ActiveTrust DNS

Treads Gone Wild summer race series is heating up!

Round 3 of TGW is now in the books, and it’s becoming a very VERY tight series. Two rounds left and unfortunately, I’m in danger of losing my 3rd place standing in the series.

Bryan is how tied with me for third, and he’s brought his A-game, winning last nights A-Main.

I qualified 5th running my black and yellow Cow Car 3 Kyosho Ultima SC-R Short Course, controlled with a Spectrum 2.4GHz DX-3R DSM2 controller.

Despite some mistakes in driving, the Kyosho Ultima SC-R is a nearly unstoppable machine. In fact the series points leader is also running a Kyosho SC, which seriously mitigates any advantage in running the best short course R/C truck money can buy. Regardless, it was a worthwhile change out from the SC-10. By changing trucks I went (virtually overnight) from a back of the pack running to a consitant podium finisher, and have a handful of wins, something that seemed impossible for me to accomplish with the SC-10.

Evolution of a theme – New race body debuts at “Treads Gone Wild”

With the slow destruction of my old race body, the damage done to the very old temporary body, and the debut of the BRCR Summer Race Series “Treads Gone Wild”, it was high time for a new body. But, time was not on my side, so my original plan of a complex and amusing theme was out the window.

When I originally started to race the first Cow Body truck a few months back, it was a big hit at the track. Despite it’s very simple design, and the multitude of very nicely done air-brushed artwork on other trucks, the amazing acceptance was, to say the least, surprising!

SC-10 "Cow Car"

Short Course racing takes it’s toll on these little Lexan bodies, so replacement is just part of the hobby. The neat part is that you are not stuck with a design forever. The bad part is that you can’t keep using your awesome design forever. I purchased a couple of new bodies on sale, and set them aside for the future. You never know when one will develop a catastrophic crack and need to be quickly replaced. With speeds of 30 MPH+, aerodynamics actually does matter.

“Cow Car 1” suffered a pretty nasty break in the rear mounting locations, and had to be retired about a month ago. But I was not ready with my new design concept, so I pulled an old Traxxis Slash body out of the dustbin of bodies past (for reference Traxxis is a good basher brand, but it does not have a reputation for real race performance). It was a musing for a while. People were shocked to see a crappy old Traxxis running so well and so smoothly on the track. LOL. Little did they know, at first, that it was covering arguably the best Short Course currently made, a Kyosho SC-R. But the body is pretty cheap to start with, and it was not long before the stresses of a very competitive race class took it’s toll too. Again, I was not ready with a new design.

After procrastinating for months, and with the start of a new Summer Race Series at our track “Treads Gone Wild“, despite my air-brushing skills being squarely in question, I had to come up with something fast! I literally had but a handful of hours to get a concept, design the pattern, lay it on the body and paint it up! Traxxis body was severely damaged in practice Friday night (so was the truck, but that’s another story), so I could not simple use the Traxxis body for the opening of the serious, and I had to fix the truck too. All in the matter of a few hours yesterday morning. Plus, it was the first warm sunny weekend day this year, so I also had to squeeze in some motorcycle riding. Had to act fast.

The “Cow Car” theme had stuck, racer announcers started to call me “Cow Car Dave”, and people expected to see me cowing it up. But I didn’t want to do the same old thing, again. Plus I wanted to experiment around with some design elements, like flames or tears. I spent some time looking at all the awesome designs in this RCTech air brushing thread, and It hit me. I could do both! So, I did!

In less than 3 hours, I knocked out this little gem, combining my first attempt at airbrushing rips, and adding drop shadows, but still sticking with the “Cow Car” theme (between “Cow Car 3”, shown here, and Cow Car 1, I also painted up a Cow Car for my daughter… more on that later.)

TA DA!

Cow Car 3

It’s pretty rough, and there are a lot of mistakes in it. Some of it because I was rushing, most of it because this is only the 2nd body I’ve tried to airbrush (the first body was “Cow Car 2”, in the middle).

A lot of people liked the design, and I do too. I got my rips, my neon color and stuck with the Cow theme. All in all, pretty good. But, now, I’m really starting to enjoy the air brushing thing, and I want to keep practicing, and paining more bodies, but, I have all the bodies I need for my race vehicles. I guess I could just go and buy more bodies, paint them up and maybe sell them for cost at the track, so that I can practice, and not go broke doing it.

Finally, here is the full family of Cows, 1, 2 and 3 (left to right).

OSX Lion (10.7) Arrives

The LION has arrived, and is being installed on millions of devices around the world. Or, so it would seem based on how long it took to download the 3+ Gigabyte latest version of Apple’s OSX operating system. And at the reduced (by $100 from the last update) price of $30, I imagine it’s going to fly off the virtual shelves. I say that because, for the first time, there are NO CD install options (or so said Apple during WWDC 2011). Watch that long but informative video here:

WWDC 2011 – LION, iOS5, iCloud Preview

Before I ramble on about some of my favorite features, it’s important to point out that this upgraded is not for everyone. Slower Code 2 Duo systems will see a little slowdown in how things run. Even on my early Core 2 Duo system with a measly 2GB of memory, it’s not much more than an occasional annoyance when things load. Once everything is up and running, I don’t see any performance hit. The new version is also limited to certain processor classes, so unless you have one of these processors, the installation instructions say you won’t be able to enjoy the latest:

    Supported Processors

  • Core 2 Duo
  • i3
  • i5
  • i7

Once you download the software, it took about 40 minutes to complete the installation. It’s a hands-off install (I ran mine overnight) once you have it started. You can walk away, come back about 1 hour later and you are ready to go. No nasty multiple restarts and driver re-installs or trash like that.

By now, you might be wondering, or saying out loud “So what? How do I buy this supposedly great upgrade?!?”. It’s not a single step operation, but overall all it’s pretty simple.

The first thing you will need to do is run the Software Update:

Select the 'Software Update' option from Apple dropdown.

This will upgrade your Apple App Store (seen down there in the taskbar, this is not the same thing as your Apple iTunes App store for handheld devices).

Find the App Store in Taskbar (3rd from right in mine)

From there, you will easily find the LION product you can purchase.

Apple App Store - LION download is VERY easy to find.

If you have not yet purchased it under your Apple ID, then you will be offered the product at around $30. Now, here is the part that I really like, if you have already purchased the upgrade (such as me), you don’t have to pay for it again, to install it on another device that you own, and have linked to your Apple ID! This is fantastic! Not only is it very inexpensive, the installation process is designed to work well for families and people with multiple systems. Something a competitor might learn something from…. (although I’m sure they would screw it up 1000-way to Sunday, LOL).

Once installed, you are flooded with 250 NEW features in the latest incarnation of OSX. That’s not 250 enhancements, that 250 NEW Features! Wow. So, what are those features? I’m not going to list all 250. I’m not even going to spend much time trying to describe them myself, so I’ll direct you do the Apple website, and you can pick the ones YOU are interested in:

250+ New Features in OSX LION

Now, the ones I’ve really enjoy so far are these:

Launchpad

[details] I like to keep the items I run often in my taskbar, but there is not room to keep everything I might ever run there. When I want to go find some seldom used app, I used to have to use the Finder, open Applications and poke through list. NOT ANY MORE! With a simple 4-finger swipe on the track pad (or clicking that rocket icon you might have noticed in my screen shot above) you are given an iOS (that’s iPhone/iPad/iPod style interface for the techno-neophytes that are now lost). ALL of the apps are there. If you have too many to fit on one page, well, you just swap left and right, find what you want an LAUNCH! It’s a really cool feature!

View of the Launch Pad

You can see that Apps in sub-directories are presented in the same method as they are on the iOS OS. When Apple said they took usability lessons from iOS and brought them to LION, it was much more than just some marketing hype. It’s real, and it works.

Mission Control

[details] Spaces has been changed too, and now it’s Mission Control. Like multiple desktops (like me) then you can access, add, remove them with a simple 3-finger up-swipe to see all your desktops:

Spaces - access to multiple desktops

It’s easy to move running apps from space to space too, and you might notice the dashboard is the first desktop on the right, so you can get there using spaces. So, why is that cool? Well, to shift from space to space it’s a simple matter of a 3-finger swipe left or right to access the space you want. Again, it’s just that simple!

Autosave

[details] This is such an awesome, intelligent, useful feature. Gone are the days of you cursing because you forgot to save a document, and for some reason the application closed, maybe because you restarted and forgot it was open (although the OS will remind you), or the system crashed (I’ve NEVER had my MAC crash.. EVER), or you simple hit the wrong button and didn’t save! OH NO. Well, this has you covered. Gone are the annoying popups (do you want to save?), because it will save it for you, when you need it to. Combined with Versions.. you have a very secure and safe environment in which to create, anything.

Versions

[details] And it will save different versions of your document AS YOU EDIT, so you can revert back to a previous state at any time. If you are familiar with time machine, you’ll understand how it works. I don’t have a demo to show you on my computer (yet) but I’ve tested it on another. This is one you want to read about for sure!

Having used the new OS for only 24 hours how, I’ve just scratched the surface of the new capabilities. I will say with complete confidence, I am glad that I upgraded, I’m using the Launch Pad and Mission Control heavily already.

iOS SDK with XCODE 4.2 is a huge change from version 3.x

Wow.. talk about a learning curve. The new iOS SDK 4.x (new to me, have not been writing iPhone apps much this year) is a radical change from the version I learned with.

I don’t doubt that I’ll find my around and start re-compiling my code with the new SDK for both iOS4 and iOS5 soon, but right now, I’m stalled trying to do something pretty simple like adding a 3rd view to the Tabbed interface. Once I get my old code ported to the new SDK, tested for 4.3, I’ll start working on the 5.0 version to be released later on this year.

At least the weather outside is HORRIBLE, so I’m not missing out on any quality MC riding today. :/

American Heros Day – Boeing Museum of Flight

What a fantastic Day at Boeing’s Museum of Flight. It was American Heroes Air Show at the museum. A day dedicated to the men and women that keep America safe by protecting our borders, fighting crime, rescuing us when we are lost or in peril, and saving lives when immediate medical care is required.

The morning started out very slowly. With less than ideal weather over Boeing Field, but the people still arrived early (before 7:00 AM) to watch and photograph the helicopters as they arrived. All were scheduled to arrive between 7:30 and 10:00 AM. Breakwater Insurance was on hand to provide complementary coffee, hot chocolate and muffins for the small crowd that had arrived 3 hours before the museum opened, to watch these wonderful aircraft arrive. They remained outside, in the weather serving the crowd late into the morning. That was appreciated.

We’d heard one helicopter transit the airfield above the clouds, so there was a brief bit of excitement, but after 10 minutes, we didn’t hear it any longer, and it was gone. People didn’t give up though, and at 8:30 AM, the thrilling arrival of the first helicopter via air (A King-5 news helicopter arrived before hand, on a trailer…. much to the crowds disappointment!).

First to arrive was the US Coast Guard in their short-range rescue helicopter, the Aérospatiale HH-65A Dolphin.

USCG - Aérospatiale HH-65A 'Dolphin'

They made a quick approach down the main runway, and then landed just outside the tarmac gates for the museum.

Not more than 10 minutes later, the second USCG helicopter arrived to the field:

USCG - Sikorsky HH-60J 'Jayhawk'

To say that it arrived with a lot more flare than the other helicopters that morning, would not be an overstatement.

USCG - Sikorsky HH-60J 'Jayhawk'

Once it had established over, the leading blades were creating just the right disturbance in the air, to create these contrails. And I’m pretty sure they were NOT splaying chemicals or conducting other experiments upon us with the contrails (that’s a contrail folks, not one of those mythical chemtrails). Unfortunately, I did not get any photos with the contrail in shark focus. :/

USCG - Sikorsky HH-60J 'Jayhawk'

Not long after the HH-60J was shut down on the taxiway, a Eurocopter AS350 arrived, and was directed to the landing area.

LEO - Eurocopter AS 350 B2

By now it was 8:35 AM, and the private museum members only presentation of the newly restored HH-52 USCG helicopter in the museum was about to begin, so AJ and myself hurried into the museum for the 1 hour talk about the history of the HH-52 (the USCG website has a writeup about this dedication).

Rear Adm. Gary T. Blore, Commander of the 13th Coast Guard District and current Ancient Albatross gave an excellent presentation of the helicopter, and related his own stories flying these historical life saving machines for the USCG. It held even the attention of a 9 year old body for the entire hour. If you wonder what the designation “Ancient Albatross” means, in short, it means he is the oldest active duty aviator in the USCG at this time (he’s retiring this summer, and the title will be passed to the next eldest in the fleet).

USCG HH-52 Seaguard

Among the stories and facts relayed. We learned;

  • the HH-52 is credited with over 15,000 lives saved
  • it has a boat hull that allowed them to land on water to recover survivors (a technique that is no longer used, because it was really quite dangerous)
  • Adm. Blore had to ditch ad HH-52 on his first mission into the Atlantic, at night, due to bird strikes that disabled the engine and severely damaged the main rotors
  • that Boston Whalers seemed be involved in an awful lot of rescues
  • they had a very limited carry capacity, despite the size, due to single motor being down-rated for cost-cutting measures (re-using existing hardware for the transmissions), sometimes only being able to pull 2 survivors at a time out of the water
  • off-shore navigation before off-shore LORAN and GPS was via dead-reckoning and that is quite difficult. Often they arrived back to the coast with very little fuel and far from an airfield, so they would land on the beach and call for a fuel truck

During the talk, several more helicopters arrived to the field. One of which was this US NAVY Rescure Hawk:

US NAVY HH-60H Rescue Hawk

With the museum opening to the general public in less than 1/2 and hour, and the new arrivals to the static displays, we hustled outside to see take it all in.

One of the first birds out was the Airlift Northwest Agusta. I see this helio a couple of times per week, landing across the street, but I still love to see these thing fly.

While talking to the pilot, I learned some interesting things about this specific helio, such as it’s complex auto-pilot allows them to fly in IRF conditions with just a single pilot. In fact, it does not even have a control stick in the left front. The only person with any controls is the pilot. And like he said, everyone on board is counting on him to be healthy during the flight.

Just like it’s arrival, the departure of the Chinook was an event in and of itself. It’s a pretty big bird and there seems to be a lot of work the flight crew has to do, just to get it up and rolling. LOL. But it’s such a great work horse, and an amazing thing to see taking flight, with it’s big counter-rotating main blades. Just another bright moment that day.

US ARMY Chinook CH-47D

One of the last birds out, was the DEA Eurocopter. The pilot took off with a standard departure to the south, but at the end of the field, kicked the rudder hard over, banked it high and came back down low over the flight line, before completing a standard northern departure. All of those helio pilots sure seemed to love their jobs!

LEO - Eurocopter AS 350 B2

What a great event at the Museum of Flight. Even the bad weather did not damping the activities on the flight line.

It was fantastic to meet and learn from these American Heros. The people out there on the front lines of national defense, law enforcement and search and rescue. It really makes me Proud to be an American.
