Serbian Field Marshal Stepa Stepanovic I WHO DID WHAT IN WW1?

Serbia’s turbulent history of the late 19th and early 20th century created some hard-boiled military leaders to the front lines of World War 1. One of these was Stepa Stepanovic – but he was not just hard boiled, he also stood with his country throughout the entire war which included the Serbian Exodus to Korfu.

Sensible reasons to reject a Canadian peacekeeping mission in Africa

Ted Campbell explains why it would not be a good thing for Canada to send a peacekeeping force to Mali (or to anywhere else in Africa right now):

The Globe and Mail, in an editorial, asks the key question:

“Is there a Canadian national interest in sending troops to Mali?”

I suggest that unless and until the Trudeau government can say, “yes,” and can explain that vital interest to most Canadians that sending Canadian soldiers off to Africa on a United Nations operation is problematical. “The Canadian Armed Forces shed blood and lost lives during the decade-long mission in Afghanistan,” the Globe‘s editorial says, “Sending them into a similar campaign in Mali may further Liberal political interests. But does it serve the national interest?

Now, I believe that I can make a sensible, mid to long term case for Canada to be “engaged,” politically, economically and militarily in Africa:

  • Africa will be, after Asia, the “next big deal” for economic growth, trade and, therefore, profits;
  • Canada will want to be involved as a trusted friend when Africa is ready to “blossom” and have an economic “boom” of its own; and
  • Despite Chinese and French incursions there are still plenty of opportunities for Canadian engagement.

In other words, we have interests in Africa; even, perhaps, in the mid to long term, we have vital interests, at that.

I cannot make a case for getting involved in any United Nations mission in Africa. I cannot, even with rose coloured glasses, see one single United Nations mission in Africa that is working, much less succeeding and doing some good.

I’m not opposed to the UN. In fact, I’m one of those who says that if it didn’t exist we’d have to invent it. The current UN is better than the old League of Nations, and some UN agencies, like the International Telecommunications Union, for example, do good work for the whole world and are, alone, worth our entire UN contribution, but we ask too much of the UN and it is neither well enough designed or led or organized or funded to do even a small percentage of what is asked of it. Peacekeeping is one of the things that the UN cannot do well in the 21st century. Peacekeeping was fine when it was ‘invented’ (circa 1948, by Ralph Bunche, and American and Brian Urquhart, a Brit, not by Lester Pearson in 1957, no matter what your ill-educated professors may have told you) but it could not be adapted to situations in which there is:

  • No peace to be kept;
  • A plethora of non-state actors who are not amenable to UN sanctions.

A few days ago I wrote about the risks involved in sending soldiers to Africa. The Globe and Mail‘s editorial just adds some more fuel to that fire.

Using the Banana Equivalent Dose (BED) to measure hysteria in media reports on radiation

Filed under: Environment, Media, Science — Tags: , — Nicholas @ 03:00

It’s quite common to find media reports involving radiation that are heavy on the freak-out factor and light on the facts. Here’s an interesting and useful rule of thumb you can use … in the few cases that the reports actually provide any meaningful figures on radioactivity:

Long-time readers know that very useful measures of both radioactivity and radiation dose rates are the Banana Equivalent Dose (BED), and a similar measure I think I invented (because no one else ever bothered) called the Banana Equivalent Radioactivity (BER). (The units here are explained in my old article “Understanding Radiation.”)

Bananas are useful for these measures because bananas concentrate potassium, and a certain amount of that potassium is ⁴⁰K, which is naturally radioactive. The superscript “40” there is the atomic number, or the number of protons in the nucleus, of that particular potassium (symbol K) isotope. Because of that potassium content, bananas are mildly radioactive: a medium banana at around 150g emits about 1 micro-Sievert per hour (1 µSv/hr) and contains about 15 Becquerel (15 Bq) of radioactive material.

(Why bananas? There are a lot of plant-based foods that concentrate potassium. It is, however, an essential rule of humor that bananas are the funniest fruit.)

Our radioactive boars are considered unfit at 600 Bq per kilogram. So, a tiny bit of arithmetic [(1000 g/kg)/150 g/banana × 15 Bq/banana] gives us 100 Bq/kg for bananas. All right, so this boar meat has 6 times as much radioactivity as a banana. Personally, this wouldn’t worry me.

So let’s turn to the radioactivity detected off the Oregon coast. This is 0.3 Bq per cubic meter. Conveniently — the joys of metric — one cubic meter of water is one metric tonne is 1000 liters is 1000 kilograms, so the radiation content here is .0003 Bq/kg.

15/0.0003 is 50,000. So, bananas have 50,000 times more radiation than the seawater being reported.

Making a Poor Man’s Mitre Box with Paul Sellers

The best way to get hold of a mitre box that suits your needs is to make your own. In this video, Paul shows how he makes one in a matter of minutes that guarantees accuracy, especially when used in combination with a shooting board (link to shooting board video). They can be used for many things such as trim for tool chests, boxes and drawers as well as picture frames and the like.

QotD: How may I interrupt you next?

Filed under: Business, Economics, Quotations, Technology — Tags: , — Nicholas @ 01:00

Q: What do Google, Facebook, Twitter, Apple, and Samsung all have in common?

A: Their business models involve interrupting you all day long.

Individually, each company’s interruptions are trivial. You can easily ignore them. But cumulatively, the interruptions from these and other companies can be crippling.

In the economy of the past, companies made money by being useful to customers. Now the biggest tech companies make their money by distracting you with ads and apps and notifications and whatnot. I don’t mean to sound like an alarmist, but I think this is the reason 80% of the adults I know are medicating. People are literally being driven crazy by a combination of complexity (too many choices) and the Interruption Economy.

There are days when my brain is flying in so many directions that I have to literally chant aloud what I need to do next in order to focus.


I’m wondering if you have as many distractions in your life. And if you do, can the chanting help you too? The next time you have a boring task that you know will be subject to lots of interruptions, try the chanting technique and let me know how it goes. It probably won’t cure your ADHD but it might help you ignore the tech industry’s distractions until you get your tasks done.

Bonus question: The economy has evolved from “How can I help you?” to “How can I distract you?” Can that trend lead anywhere but mass mental illness?

My hypothesis, based on observation alone, is that the business model of the tech industry, with its complexity, glut of options, and continuous interruptions are literally driving people to mental illness.
