Manipulating Traffic Data

The first GPS navigation devices for cars were strictly “dumb” in the sense of picking optimal routes on speed or distance. The past few years have seen models incorporate traffic information to perform on-the-fly route optimization. That information used to come through inaudible frequencies through FM radio but the prevalence of smartphone GPS navigation applications is shifting that to a direct pull via the Internet. But how has that data been derived? Many of those smartphones in cars are transmitting speed and location information back to central servers that aggregate the data to determine flow rates on traffic routes. However, due to users demanding privacy, the traffic aggregators cannot guarantee authenticity of the originating source. What does this mean? Well, a BlackHat presentation shows a proof-of-concept for falsifying traffic data in order to “control” the information passed back to drivers. (pdf)

Distributed Internet Mapping

What would the most effective way to map the entire Internet in a short amount of time? Distribute the scan out as far as you can and then aggregate the results in order to farm the processing, bandwidth and network reach of others. One researcher took the time to craft a script designed to access insecure embedded device across the Internet using default credentials. Then, leveraging all of those devices he launched nmap scans of the entire IPv4 address space to paint a picture of the 2012 Internet. Who knows, there’s a good chance your Internet modem or Internet enabled device (TV, DVR, etc.) participated in the scan.

Cummins 4BT Jeep Wrangler TJ Diesel Conversion

It took me awhile, but I finally finished writing up my build article – Cummins 4BT Jeep Wrangler TJ Diesel Conversion – on converting my 2006 Jeep Wrangler over to diesel. My 4.0L died back in 2011 so I was faced with the cost of replacing the engine anyway otherwise I wouldn’t have ever considered doing it.

Since the conversion completed, I’ve put 13,000 miles on her in the past six months. As long as I keep her in the right RPM band, she gets 28mpg at 55mph (4th gear). That quickly drops to 22mpg at 70mph (5th gear). I would imagine a 2nd generation Cummins 4BT with electronic management could do even better. Another way to look at these efficiency gains is 7.27 miles per dollar for diesel compared with 4.16 miles per dollar for regular unleaded at today’s prices. I should be able to improve those numbers once I get the Bosch VE fuel pump leak fixed (it drips out a lot of diesel right now). Leak or not, with my 31.5 gallon Safari tank, it’s pretty nice to go 700 miles before the fuel light comes on and know that I still have 182 miles left before empty!

Venezuelans ... They Be Crazy

Hugo Chavez continues to influence the world, his final act being to make a personal, elbow to elbow recommendation to Jesus on a new pope. As spoken by Nicolas Maduro, the acting Venezuelan President, “We know that our commander ascended to those heights and is face to face with Christ. Something must have influenced [Jesus] to call for a South American pope.” Of course, Maduro is also opening an investigation into his death because, “we have the intuition that our commander Chávez was poisoned by dark forces that wanted him out of the way.” The Venezuelans believe foreign agencies, particularly the United States, are responsible for giving him cancer. Such a belief probably propagated because Chavez himself alluded to exactly that in a speech to his soldiers, “would it be strange if they had developed the technology to induce cancer and nobody knew about it?”

Bottom-Up Tax Model

I’m in the middle of The Benefit and The Burden (which is very interesting, albeit un-engaging and somewhat repetitive) and it has me thinking taxes. There’s so much standing in the way of fairness when the federal government raises revenue, and no matter where you try to fix things, someone gets burned.

While there are no doubt more impactful angles, as I put down my Kindle-via-iPhone in response to the fresh green light last week, I wondered if one of the problems isn’t the vast chasm between the individual and the Federal Government. The former pays the latter and expects the latter to serve … but the latter isn’t really configured to serve the former; it’s made to serve something in between (the States). The States, too, aren’t made to serve the individual, but the municipality – and there we finally reach the level positioned for the originally sought service.

Surrogate Mother and Abortions

A new quandary has arisen with surrogate parenthood. A family opted to pay for a surrogate mother due to fears for the biological mother’s survivability. During routine natal examinations, it was discovered the fetus had developmental abnormalities whereupon physicians declared it only had 25% of living a normal, healthy life. At this point, the family requested the surrogate mother have an abortion as they were not prepared or able to handle a medically needy child and offered financial compensation. The surrogate, however, refused.

How should a situation like this best be handled?

xBox Combat Medal

The Secretary of Defense recently authorized a new medal for military service members, the Distinguished Warfare Medal (pdf). It can be awarded for members of the armed forces “who distinguish themselves, on or after September 11, 2001, by extraordinary achievement, not involving acts of valor, directly impacting, through any domain, combat operations or other military operations” which basically gives drone operators or cyber operators an opportunity to be recognized. This is not necessarily a bad idea, until one looks at the line reading that it “provides an avenue to recognize appropriately extraordinary direct impacts on combat operations warranting recognition above the Bronze Star Medal.” The order of precedence has stirred up a number of veterans calling the award an insult to those performing valorous or heroic acts. The term “xBox Medal” is definitely being thrown around within the ranks already. A petition is already on the White House website requesting the precedence be re-evaluated.

Iran's Science - Real or Fake?

Let’s just say the Iranians have been caught fudging their weapons tests to the public before. Their recent announcement of a stealth fighter has been met with extraordinary criticism that the vehicle is a mere mockup and completely incapable of actual flight. One comment indicated it looked like, “Iranian designers went back through the catalog of cool combat aircraft, picked out some of the coolest bits, and just stuck them all together to make a new airplane with a badass look about it.” Even before that, the Iranians were hyping up their space launch with a monkey aboard that is increasingly in doubt as well. Upon it’s “return”, the Iranians apparently displayed a different monkey than the one photographed for the launch, which they now claim was a photo mixup. Uh huh.

Assassination Rules

The US government doesn’t assassinate American citizens, right? Apparently NBC has obtained a leaked 16 page memo (pdf) defining the Justice Department’s rules for assassinating Americans. At the heart of the discussion on the NBC story are Americans Anwar al-Awlaki and Samir Khan who were killed in an airstrike in Yemen. Does the government actually have this power to kill at their discre …

Ban Nerf Guns!

I submit, the Nerf N-Strike Stampede ECS-50 Blaster. It features:

  • pistol grip
  • semi-automatic functionality
  • extended 18 round magazine
  • military-like front bipod
  • military-like carrying handle
  • military-like adjustable stock

And for a Nerf gun, it’s one of the most intimidating models out there. This single weapon meets EVERY SINGLE piece of criteria for the assault weapons ban! I also submit the commonly used logic that it serves absolutely no practical purpose other than to simulate killing. These should be banned immediately.

Boosting US Cyber Security?

I’ve bitched before on OmniNerd about the DoD scraping the barrel to find “cyber savvy” people to fill the ranks. It looks like CYBERCOM is now attempting to increase its size fivefold very rapidly. With WHO? The place already staffs itself with people that preface their meetings by stating, “So I’m just a dumb infantry guy”. On the job training is one thing, but OJT from other people that don’t know what they’re doing is downright shameful.

All right, listen up. I want ten, light netbooks to flank the adversary’s network from the west under the cover of a volley of suppressing packets. The big iron mainframes will send full packets, not just with 0’s but heavy payloads of 1’s at the maximum transmit size in order to pulverize their firewalls and defenses. This will allow the flanking light netbooks to quickly transit the network in order to double-tap the remaining hosts with a flurry of light packets. Any questions? Yes, you, the nerdy looking one in the back.

Gifts from Friends and Strangers

So I’m old now. The “big four-oh”. Sort of feels like Friday.

I started to write something all introspective and “judgy” about where I am in my life, and I realized how mind-crushingly cliché that is. “Cliché” I can handle; “mind-crushing,” not so much.

Let me instead mention some gifts I’ve unexpectedly gotten over the years, usually not on my birthday, that have helped me to get to today and will hopefully carry me on for at least another forty years.

Ancient Wisdom and Management Fads

This gift is credited to Ken Bralich. It would have been about fourth grade. We were at my house, in the back yard around my family’s pool. Ken watched me with puzzlement as I laboriously dried myself off from the feet up, having to go back often and re-dry places I’d already visited. Ken looked at me and said “You know, Jim, if you just dry yourself off from the top down, you won’t have to do it all over again”.

National Hacking Day

According to a press release by the White House Office of Science and Technology, 1-2 June 2013 will be a national hacking day. From the article:

“Civic Hacking Day is an opportunity for software developers, technologists, and entrepreneurs to unleash their can-do American spirit by collaboratively harnessing publicly-released data and code to create innovative solutions for problems that affect Americans. While civic hacking communities have long worked to improve our country and the world, this summer will mark the first time local developers from across the Nation unite around the shared mission of addressing and solving challenges relevant to OUR blocks, OUR neighborhoods, OUR cities, OUR states, and OUR country.”

Why don't you vote on OmniNerd?

I’m curious as to why the regulars on this site are so reluctant to vote on content. You’re logged in, you’re reading and commenting, but the 1-second process of casting a vote rarely seems to occur. Is there a reason you’re not? If not, I suggest voting for things that you both read and didn’t feel was a waste of you’re time. In doing so you accomplish two things: you move good content to the top, and you let the writer know you read their stuff and thought it was a useful read.
