I really enjoyed Ben Rich's book on Skunk Works.

Skunk Works is a great book with many great stories about the U2, F-117, and SR-71 programs. I got my copy off the shelf to be sure I didn't mis-remember some items. The U-2 flew up to at least 74,500 feet with a 65,000 cruising altitude. Missions could exceed 6000 miles and last 10-12 hours. The window between stall speed and overspeed buffeting could be so narrow that "our test pilots reported that sometimes during a turn the inside wing would be shaking in stall buffet while the outside wing was shaking more violently in Mach buffet.", and the wings were so light that they flapped up and down. The chapter about the unsuccessful hydrogen plane program is titled "Blowing up Burbank"

Comment Unrestrained driver safety (Score 5, Insightful) 891

One of the US crash safety standards required by the NHTSA that adds weight and expense to new vehicles is for "unrestrained drivers", despite the fact that under 10% of US drivers go un-belted these days. The punch line is that the IIHS found the NHTSA test not very useful, because un-bented passengers often aren't held in place in front of the intended safety devices.

NYT financial columnists Andrew Ross Sorkin's book "To Big To Fail" documents events approx from Lehman Brothers' collapse to TARP.

Chapter 20 details how CEOs of the "big 9" we summoned to an unexplained a meeting by Henry Paulson and told by Treasury that they would all be participating in TARP, and how much each would receive: "Bank of America: $25 billion; Citigroup: $25 billion; Goldman Sachs: $10 billion; JP Morgan: $25 billion; Morgan Stanley: $10 billion; State Street: $10 billion, Wells Fargo: $25 billion." (the book omits who the last two banks were and how much they were to receive) When Wells Fargo CEO Dick Kovacevich objected, Henry Paulson to him "Your regulator is sitting right there" "And you are going to get a call tomorrow morning telling you you're undercapitalized and that you won't be able to raise money in the private markets".

Other points of interest in the book- The picture of the $9 billion check Mitsubishi used to invest in Morgan Stanley

Personally, I enjoyed Michael Lewis' "The Big Short" much more.

Comment Re:What about Google driverless car? (Score 1) 603

A good driver, by definition, mitigates the bad driver by taking appropriate actions to reduce the risk. It is not how you drive, its how you manager the drivers around you that makes you a good driver.

You are stopped at a red light, cars are stopped ahead of and to either side of you. Driver approaching behind you is distracted and doesn't see that you are stopped. Any suggestions for mitigating this impending collision?

I wonder if they've had any success with the opposite -- trying to get rid of memories. I bet there'd be a big market.

Yes, inhibiting protein creation while a memory is being recalled, which actually re-creates the memory, can prevent the memory from storing again. There have been human trials. This Radiolab discusses it http://www.radiolab.org/2007/jun/07/

Comment Re:Am I missing something? (Score 1) 170

Not idiotic at all, you made good inferences. The current popular systems have an optical beam transceiver and reflector pair at both the start and finish lines, which are hard wired to a fairly simple timing box with multiple time displays that can track 2 or more (typically 4) times simultaneously (which also limits how many vehicles can be on course at once), with the oldest time being replaced by the newest time, so timing integrity is not dependent on the PC, but on the "simpler" hardware inside the timing box. As events are timed to the thousandth of a second- with "dead heats" occurring even then, depending on a PC for timing accuracy is not the best choice. At our events, one of the T&S staff's job is "manual time log"- writing every new time down direct from the timer box, along with the vehicle or event causing the trip- tumbleweeds, false trips by workers, rain, snow (which happened this year), etc, to generate an independent audit trail of results. The timing box sends new times to a PC running the T&S software via a serial connection. The T&S software operators enter cars in the start queue into the software, make adjustments for wrong/ missing numbers, false trips, extra trips, etc in real time. Cars are sent onto course approx. every 30 seconds for a safety margin, with runs lasting from 30-70 seconds depending on the size of the course. On a large course, 3-4 cars is about the max on course at a time.

Comment Re:GPS? (Score 1) 170

Current optical timing systems for autocross time to the thousandth of a second- and there are dead heats even then. So GPS is no where near accurate enough.

Factoid- prior to national events two parallel timing systems are set up and tested against each other to ensure consistent results. IIRC, anything greater than 5 thousands variation between them calls a timing system into question.

maybe let's at least try to read the article and then the Wikipedia article about whatever we are posting about and at least attempt to flame those that don't. Nobody up for that?

If we look at this a bit further, the obvious alternative to US treasuries would have been AAA rated securities, such as the collateralized debt obligations which more or less caused the current economic crisis. That makes this paper pretty foresighted.

Ok, I've read. From page 1 of the paper "The financial services industry has grown tremendously in this country over the past eight years, and done a very good job of handling growth and the increased risks that accompany it. The industry accomplishes this task most fundamentally by separating risks by type, making them easier to evaluate and price." From this, I question that the paper is "foresighted"

It was the failure to understand CDOs and accurately assess their risks by the issuing banks, S&P and Moodys, and their government regulators that caused the most recent financial calamity. Michael Lewis' "The Big Short" has good insight into the mortgage bond market melt down.

As there was no significant (not just token) firings, prison time, and lawsuits for the banks, ratings agencies, and their federal regulators, another round of this type of economic catastrophe will occur again soon, and on a larger scale.

Comment Practical experience with autox T&S systems (Score 3, Informative) 170

I'm an autocrosser with experience setting up, maintaining, and troubleshooting both an older T&S system, and the new system used by the SCCA at national events. Ours was the first local region to install the new "national" system, so I'm familiar with the "issues" surrounding the current T&S options.

There are several practical issues with optical systems for automated vehicle recognition- number and class markings are already tough to get consistent without requiring an additional barcode or QR large enough (some competitors would gripe about a huge barcode) to be useful at the 30'+ distance finish line sensors are set back to minimize getting hit by spinning cars. Add in the fact that existing markings some times fall off on course, or competitors in dual driver cars forget to change numbers between runs, and it's tough to be certain you'd have something consistent to try to recognize.

The national T&S system uses a wireless barcode reader operated by a worker in the starting queue to read stickers placed on competitors helmets to register cars in the T&S software. Locally, we position the T&S trailer to allow the operators to manually enter vehicles as they enter the start queue. Human eyes really are the most flexible here "shouldn't 80ES be 180ES?".

I like one of the comments above about a webcam triggered by the finish light taking a picture with a clock display in it. Unless there was OCR to immediately post the result to the software, the results feedback would be too slow for our region- we have real time announcement of finish stats, and the software can post results to a web server real time for smartphone access in paddock. The T&S software uploads a small file to the web server in the 20ish second gap between finishing cars.

Apologies for not offering solutions, but hopefully the extra info about some of the issues can help shape a solution.

Submission + - Intel Series 320 SSDs: 600GB to 8MB If Power Lost (tomshardware.com)

jafo writes: "Over the last couple of weeks there have been many reports that Intel Series 320 SSDs, including the mighty 600GB version, are downgrading to a capacity of 8MB. Speculation is that this is caused by the drive being disconnected from power. Intel has responded with few details other than that they are working on a firmware fix. My own personal experience has been a nearly identical failure over the weekend of a 32GB Intel X-25E Enterprise drive, forcing me to wonder if the problem is more widespread than just the Series 320."
