Detecting Photoshopped images – a primer

Filed under: Media, Technology — Tags: , , , — Nicholas @ 10:18

I’m sure almost everyone saw dramatic and scary images of “Hurricane Sandy” like this one that went round my friends’ Facebook timelines yesterday:

As you’ve probably guessed from the title, this is a ‘shopped image. RJS Security has a quick primer on detecting doctored images using this example:

Whenever a major media event happens (like Hurricane Sandy), we are inundated with news. Sometimes that news is useful, but often it merely exists to create FUD… Fear, Uncertainty and Doubt. While I have not personally seen any malware campaigns capitalizing on the event yet, it is inevitable. The pattern is generally as follows:

  1. Event hits the news as media outlets try to one-up eachother to get the word out.
  2. People spread the warnings, making them just a little bit worse each time they are copied.
  3. Other people create hoaxes to ride the wave of popularity.
  4. Still other people create custom hoaxes to exploit the disaster financially.

A few minutes ago, at least in my little corner of the internet, we hit stage 3 when this image was posted

Meet the new Chief of Defence Staff, General Tom Lawson

Filed under: Cancon, Military — Tags: , , , , — Nicholas @ 09:54

David Akin reports on the change-of-command that happened yesterday as General Walt Natynczyk handed over to General Tom Lawson:

Canadians have a high regard nowadays for their military.

Not only did our soldiers earn our admiration and thanks for the way they conducted themselves in the longest war in Canadian history — the last decade in Afghanistan — but the last two chiefs of defence staff did much to advance the cause of uniformed men and women with their own outsized personalities.

Gen. Rick Hillier, the top general from 2005 to 2008, was a quote machine and a favourite for the TV cameras. His popularity sometimes caused headaches for his political masters, but the troops loved him.

He was followed by Walt Natynczyk who, though not as over the top and outgoing as Hillier, was so much a favourite of the troops that he was given the nickname Uncle Walt.

Uncle Walt finished his four years as chief of defence staff Monday in an emotional ceremony at the Canadian War Museum, handing off his responsibilities to Gen. Tom Lawson with the words, “My duty is complete. The nation is secure.”

[. . .]

Lawson seems a very different leader from the two tank commanders who were his predecessors. Though he may yet flower in front of the TV cameras or develop a “bone-rattling” back-slap, he does not seem to to be the media personality his predecessors were. That’s not a criticism, but it does mean that Canadians and the 65,000 men and women who now serve under him will see a different style at the top.

He is well spoken, crisp in his speech and smart. But there is a coolness to his manner that was absent from Natynczyk and Hillier.

Beginning to assess the damage

ESR posts a “we’re fine” report on Google+ and then points out the damage to New York City’s power grid may be incredibly expensive and difficult to repair quickly:

Reporting from a diner in Paoli, PA, near 40°02′27″N 75°29′24″W.

Power went out in Malvern about 2AM this morning. After sleep, we have fled to where there is power and light and steak and eggs.

It feels like aftermath. The NOAA seems to no longer be issuing track updates and the storm track has disappeared from the Google crisis map, suggesting that the anticipated conversion to a large but normally (un)structured nor’easter has completed.

This area got off lightly, especially compared to the ration of apocalypse-now the storm handed New York City. Exploding high-power transformers are very bad news — they tell us that all that tunnel flooding seriously damaged the downtown end of the Manhatten power grid. That kind of equipment is extremely expensive and difficult to replace, and the halogen compounds they use as insulators are hazmats when they get loose. The prompt repair costs are going to be a large fraction of a billion dollars.

But that isn’t the worst of it. Considering that this will have have paralyzed the largest node in the international financial system for some time, downstream economic losses could easily crack a trillion dollars. The impact will be global and manifest as higher prices for everything with cross-border supply chains, rippling all the way down to Third-World farmers buying fertilizer.

Update: In almost record-setting time, here’s the first example of the Broken Window Fallacy to make it past the editors:

Disasters can give the ailing construction sector a boost, and unleash smart reinvestment that actually improves stricken areas and the lives of those that survive intact. Ultimately, Americans, as they always seem to do, will emerge stronger in the wake of disaster and rebuild better-making a brighter future in the face of tragedy.

Sandy is unusual storm and complex to gauge. Coming late in the season and combining with cold fronts to the west and north, it is really a post-tropical cyclone and has the potential to deliver epic destruction. However, coming so soon after Irene in August 2011, the level of anticipation and preparedness demonstrated by federal and state officials is commendable and should mitigate some losses-especially loss of life.

[. . .]

However, rebuilding after Sandy, especially in an economy with high unemployment and underused resources in the construction industry, will unleash at least $15-$20 billion in new direct private spending — likely more as many folks rebuild larger than before, and the capital stock that emerges will prove more economically useful and productive.

Pushing for “medical marijuana” makes full legalization less likely

Filed under: Health, Law, Liberty, USA — Tags: , , , , , , , — Nicholas @ 09:05

L. Neil Smith makes the point that supporters of medical marijuana may be missing:

What I do mind — and perhaps I am alone in this, who knows? — is weak and disingenuous politics with regard to drugs. It was the issue of “medical marijuana” that first got my goat this way. I don’t doubt for a microsecond that the weed makes life easier and longer for those suffering certain diseases, and I believe that those who would deny them that relief are little better than scavengers on the misery of others.

But observation — and my knowledge of history and human nature — suggests that the majority of those who advocate the legalization of pot “purely for medicinal purposes” do not require it for that reason. They simply want to slip the nose of their personal camel under the edge of the tent, and I find that approach sneaky, dishonest, and cowardly.

I believe that if they had spent the past fifty years pushing the Ninth Amendment right to roll up and smoke whatever frigging vegetable you wish, marijuana would be legal now, and there would not have been a “War On Drugs” handy for the psychopathetic enemies of liberty to transform into a War on Everything, including the American Productive Class.

I think we’ve seen the high point for medical marijuana. The proof of that lies in a current initiative to “Regulate Marijuana Like Alcohol”, on the ballot in my home state of Colorado this year. The title says it all, although the details could be gruesome, ending in a mess found in some states and all military bases, where the government runs the liquor stores (about as well as they run everything else). In the Air Force, when I was growing up, some officious snoops regularly examined the records of the store and your commanding officer would get a tattletale letter if they thought that you were buying too much booze.

Whatever that amounts to.

This is not a kind of progress any that real libertarian would recognize. The fact that advocates of the measure make a major selling point of taxing the stuff only makes it worse, both in principle and practice. First, by what right does anybody steal money from me when I choose to spend it on some things and not on others. Furthermore, when I was just entering college, a smoker could buy a pack of Marlboros out of a machine for 35 cents. Today, the price per pack is nudging five dollars, and only a small fraction of that is attributable to inflation.

Exactly the same thing will happen with marijuana.

A source of obscure and unusual do-it-yourself books

Filed under: Books, History, Media, Technology — Tags: , — Nicholas @ 08:51

Michael Bradshaw‘s letter to the editor in the most recent Libertarian Enterprise alerted me to a possible source of interesting and unusual do-it-yourself books and pamphlets:

“The Lindsay” of Lindsay’s Books has announced his retirement “in 2013 or earlier” and the closing of his book store.

For many decades Mr. Lindsay has been the premier supplier of technical books to the do-it-yourself crowd, machine shop mavens, foundry sand-crabs, eccentrics, nut cases (like me) and geniuses at large (like “Uncle Dave” Gingery).

It ain’t all Uncle Dave.

He (Lindsay, not Dave) has titles from all over and back to the mid nineteenth century. He used to have De Re Metallica by Agricola in the Hoover English translation, but I don’t know if it is still cataloged. There are tech-school text books, how-to volumes from some of the best industrial arts guys around and collections of articles from technical manuals and magazines back to the early twentieth century. Get a 1940’s version of “How to Run a Lathe” by the South Bend Machine Tool Company.

His titles cover a plethora (really!) of stuff, such as:

  • Machine shop practices, building the major tools from scratch — from scrap (the Gingery series), building EDM machines and other shop tools and techniques.
  • Foundry tools and methods. Make your own molding shop and blast furnaces for the back yard. Fuel them with charcoal, propane or natural gas. Pour castings in aluminum, zinc and pot metal, copper alloys, iron alloys. Design and build centrifugal fans to power your crucible and cupola furnaces. Make your own crucibles. Dig ore for your cupola furnace, with a sharp stick, while wearing a leather breech-clout, a tie and a top hat! (OK, that last one was a joke. Lame.)
  • Sheet metal shop tools and methods. Make your own brake and slip-roll. Books of projects. Start a local sheet metal fabricating business.
  • Make electric generators, modify alternators, re-build or modify motors, make electro- and permanent magnets. Make radios from scratch. Emulate Nicola Tesla. Short circuit yourself and go up in a puff of smoke!
  • Learn about old-time chemistry. Set up a chem-lab. Screw up and dissolve, stain, burn, poison, blow-up and generally kill yourself in the most ingenious ways! Go up in another puff of (green) smoke!
  • Make wooden toys for kids. Make ship models for yourself.
  • Make steam, sterling, turbines and other kinds of engines. Build boilers from scratch and blow yourself (and the garage) up again! Build locomotives from scratch. Well, “maybe” on that last one.
  • Make wind and water turbines to power your generators or shop. Recycle waste oils.
  • Other stuff that I forgot to mention.

Basically, if you drop a bunch of money (including postage) on Lindsay, he will show you how to make a very complete industrial revolution. You may even have some fun. While killing yourself in the most ingenious ways. Count your fingers at the end of the day.
