Tasty Weekend Eats: Shredded Pork, Soup, Subs

This weekend I made some tasty food! 

On Saturday I cut up a pork shoulder into 1-inch cubes, threw it in a pot, covered it with water and brought it to a boil with a quartered onion, garlic, and cumin. After skimming the foam, I turned down the temperature and let it simmer for one hour. For shredded pork, you need to use the shoulder because nothing else has enough fat to stay tender during cooking. This is the result: 

After removing from the liquid and letting it cool, I pulled off the fatty bits and shredded it with my fingers, while I got my soup ready:

I added a big handful of the shredded pork to a soup I made with celery, carrots, onions, green onions and pasta: 

It turned out delicious! 

Tonight I took my leftover shredded pork, mixed in some BBQ sauce, ketchup, brown sugar, and some seasonings. I put the mixture into sub buns with some cheese and grilled them on my George Foreman grill: 

The sandwich was also delicious, and I made a second one for lunch tomorrow! Woo-hoo! 

Awesome Products: TimBuk2 Command Messenger Bag

After buying a few cheap messenger bags and having them fall apart, I began the search for the perfect messenger bag - I needed the best. The best resource for finding random product testimonials turned out to be reddit. There were several discussions for "best messenger bag", and one of the most commonly reoccuring brands was TimBuk2.

I ordered my TimBuk2 bag in June 2011, and 8 months later I'm still impressed.

Purchasing
TimBuk2 has a wide selection of bags and backpacks - something for everyone. You have the option of personalizing nearly every product in their inventory, or go with a plain design (my preference, since I don't want anything too eye-popping). Most bags come in multiple sizes; good for customers with laptops large and small.

On the online store, most products have an embedded YouTube video of someone from the company handling the bag/backpack for 60 seconds and opening the pockets, so you can gauge its size. This is a surprisingly useful thing! There are also tons of user reviews on the site - both positive and critical. Being able to see what other customers like and dislike about each bag helped me narrow down my choice (and the fact the company doesn't remove negative reviews adds credibility).

Everything is handmade in San Francisco and shipping was very fast!

My Bag - the Command Messenger
I selected the Command Messenger model for its laptop pocket and for its ability to fold flat for airport security (so you don't have to take the laptop out of the bag). After taking the bag on a few flights I found it was often faster to take the laptop out anyway, rather than explain to the screeners it was a TSA-compatible bag.

The laptop pocket is bright red on the inside and the fabric has foam padding bubbles inside of it!

Inside, there is a HUGE main pocket and a handful of smaller pockets, including a pen and business card holder that could be removed (velcro). Some of the inner areas zip closed, others are open for easy grabbing. There are four outer pockets - three hiding under the velcro cover flap and one accessible through the side (perfect for house keys).

There is a secret pocket on the bottom of this bag that's perfect for laptop power bricks - the tangles of cords stay out of your way while travelling.

The bag is near-flat when empty but seems to magically expand to hold whatever I need. It's a true man-purse: you can carry things like umbrellas, light jackets, and scarves just because you can. Since the laptop pocket is separate from the main pocket, carrying a laptop doesn't really reduce your carrying capacity. I'd be able to carry a laptop and two gigantic engineering textbooks with ease.

Impressions
This bag is solid. Before purchasing, I read a few reviews where a small handful of customers had bad stitching, but TimBuk2 flexed their customer service muscles and fixed or replaced them for free.

With the main velcro cover flap, it's easy to grab stuff while you've got the bag shouldered. The strap is padded and adjustable and it's just comfortable.

The one feature missing on my bag is a comfortable carrying handle. It has a handle, but it's a one-inch piece of flat seatbelt material. If the bag is even moderately filled, carrying it with the handle can be uncomfortable.

With shipping and taxes I ended up spending about $150. It was expensive, but it was a planned, well-researched decision and I've been very happy with the result for the past 8+ months, and expect it to last a few years at least. If you're in the market for a new bag, Timbuk2 has my recommendation!

Virtual Private Networks and Why You Might Want One

On Tuesday I signed up for a paid Virtual Private Network (VPN) service. Why? In three words: privacy, security, and flexibility.

The internet is not a series of tubes as you may have been led to believe. It is a network of computers that all have to talk to each other. Sometimes it is not clear who owns what computer, if they are using it for good or for evil, or if it can access your private data.

Here's a simplification of how the internet works. Let's say you want to visit Wikipedia, so you type http://en.wikipedia.org into your browser. Your network traffic (requests you send to the internet, and the data that comes back) first passes through your local network. This is literally the network you're connected to - a router at home, a wifi hotspot at Starbucks, or maybe a computer lab on campus.

Next, the traffic passes through your Internet Service Provider's servers: SaskTel, Shaw, Rogers, etc. Finally, your traffic passes through more servers until it gets to Wikipedia's servers. Wikipedia's servers then sends information back to you the same way you received it. Anyone who is determined enough can snoop at what you're looking at - maybe someone sitting at the other side of Starbucks, or maybe someone who works at Shaw, or maybe some tricky hacker.

A VPN creates a highly encrypted and secure connection (a "tunnel") between your computer and a VPN server. If you type http://en.wikipedia.org into your browser when you're using a VPN, the VPN server "asks" Wikipedia for the info you wanted, then sends it on to you. Wikipedia won't know anything about you (unless you're logged into a user account) and it cannot tell you're using a VPN, and no-one between the VPN server and your computer can see what's going on, either.

Here's a diagram I made (all by myself!) that explains how VPN works. Click to enlarge:

It is virtually impossible for anyone between your computer and the VPN server to figure out what you're doing on the internet - whether it's paying your bills, submitting your tax return, typing a note to your sweetie, learning about dogs and cats, or watching a saucytime grownup film.

Privacy and security are good enough reasons to get a VPN - I'm confident that data I'm transmitting on my computer can't be intercepted by local hackers, my Internet Service Provider, the government, or whoever might be "listening" to internet traffic. But the coolest feature - at least for Canadians - is flexibility.

Lots of websites know roughly where you're browsing from, based on your IP addresses. It's why when you type "www.google.com" you're taken to www.google.ca. It's why Canadians can't watch lots of streaming videos, due to dumb licensing rules.

But with my VPN provider, I can pick a VPN server anywhere in the world, so my traffic looks like it's coming from anywhere in the world. I can pick a server in New York City and immediately start watching videos on ComedyCentral or Hulu (or others). Or I can pick a server in the UK and start watching BBC content.

I selected WiTopia.net as my VPN provider. They are very well-reviewed, and in my limited experience - great. They responded to a bunch of pre-purchase questions quickly and with lots of details. There are some free VPN providers out there, but it's easy enough for a 16-year-old hacker to set up a VPN server and make it look legit - so I'm paying for peace of mind. With WiTopia, you can pay by the day, month, or year, and there are lots of money-back guarantees. So check them out if you want to protect your online info and free yourself from the shackles of location-based internet!

Blog post: done. Now I'm off to watch full episodes of the Colbert Report!

Mind-Blowing Connection Between Language and Colour

Here's a very interesting 8-minute clip from the BBC on the connections between language and colour.

In short, there's a strong connection between the words that we learn as children to describe colour, and the colours that we are able to perceive (did you know that infants are born mostly colourblind?).

A key group in this research is the Himba tribe in Africa. While "Westerners" (Brits, North Americans, etc) have about 11 major colour descriptors (red, orange, yellow, green, blue, violet, brown, black, white, etc) the Himba tribe has five. When shown 12 squares of green - where one square is a SLIGHTLY different shade - the Himba can immediately detect the unique square, whereas Westerners would struggle and often guess (incorrectly).

However, when the Himba are shown 11 squares of green and one square of blue, they struggle and often guess (incorrectly). A Westerner would be able to immediately distinguish blue from green.

The scientists posit an extremely strong connection between language and colour perception. In the Himba vocabulary, "Western" blue and green are represented by the same word, and they cannot distinguish between "Western" blue and green.

Isn't this mind-blowing? We perceive the world the way we do - in part - because of the vocabulary that we've learned and evolved through language. Awesome!

Frozen Seared Steak

Robyn sent me a link to a new way of cooking steaks, promoted by molecular gastronomists - crazy chefs who come up with ingenious new ways of preparing food based on empirical observation and study, chemical reactions, and SCIENCE! It is these molecular gastronomists who have written the six-volume, 2,400 page set Modernist Cuisine,

This blog describes the frozen steak recipe and where it came from - a request for a few molecular gastronomy recipes that can be done at home with no special equipment.

Basically you sear one side of a frozen steak on a mega-hot frying pan, then immediately put the steak in the oven at 200*F for 30-60 minutes, until it's done to your preference.

Here's my attempt:

It turned out GREAT. So, so so delicious. The outside has an incredible seared taste/texture, but the inside is extremely tender and "buttery soft" as the Kitchen Konfidence blog describes. It was dead simple - no more complex than any other way of preparing steak.

Next time I will use a thicker cut of meat, then keep it in the oven for a bit longer. Everyone should try this method at least once, you'll be convinced!

Food For Thought: Cellular Data Roaming Charges

I spotted an article last week about a Regina man who incurred $10,600 in data roaming charges from SaskTel when he travelled to Phoenix, Arizona and let his grandkids watch Netflix movies over a mobile data stick for his laptop.

The man in the article was honest about his mistake and I'm not going to judge him. What I think is ridiculous is the extremely high data fees he incurred, and how they were dealt with. The article says:

"[The man] followed up with SaskTel which decided to take mercy on him and promised to reduce the $10,668.38 bill by $9,600."

That's good PR for SaskTel, but I think it highlights the worthlessness of data fees on mobile devices. While cellular carriers do incur expenses creating international roaming agreements with carriers worldwide, the $9,600 bill reduction demonstrates that data fees are mostly pure profit for telecoms.

In other words: SaskTel gave up $9,600 in pure profit to get some good PR by taking mercy on a grandfather, but their roaming data rates (and the rates of their competitors) will remain sky-high to scalp profits from ignorant consumers.

I'm not villainizing SaskTel - cellular carriers all over the world do this. So be careful with your smartphones, tablets, and mobile data sticks while travelling!

Required Reading for Acquiring a Sense of Awe and Wonder at the Universe

1) The 10,000 Year Clock

In a remote Texas desert, work is currently underway to build a 10,000 Year Clock deep inside a mountain that Jeff Bezos (of Amazon.com fame) purchased. Yes, Jeff purchased a huge parcel of land so that the Long Now Foundation - a group formed to foster long-term thinking and responsibility for the next 10,000 years - could design and build a massive, 200-foot-tall clock that only chimes one a year from deep inside a mountain.

The inventor is quoted as saying:

"I cannot imagine the future, but I care about it. I know I am a part of a story that starts long before I can remember and continues long beyond when anyone will remember me. I sense that I am alive at a time of important change, and I feel a responsibility to make sure that the change comes out well. I plant my acorns knowing that I will never live to harvest the oaks." - Danny Hillis

The project page is a fascinating summary of the philosophy and engineering principles behind the clock. For instance, virtually all modern methods of generating power - wind, solar, nuclear, chemical, geothermal, connection to electrical grid - become unsustainable over 10,000 years. So what's the best method to power the clock? Human interaction.

"To see the Clock you need to start at dawn, like any pilgrimage. Once you arrive at its hidden entrance in an opening in the rock face, you will find a jade door rimmed in stainless steel, and then a second steel door beyond it. These act as a kind of crude airlock, keeping out dust and wild animals. You rotate its round handles to let yourself in, and then seal the doors behind you. It is totally black. You head into the darkness of a tunnel a few hundred feet long. At the end there’s the mildest hint of light on the floor. You look up. There is a tiny dot of light far away, at the top of top of a 500 foot long vertical tunnel about 12 feet in diameter. There is stuff hanging in the shaft."

Once built, the clock will store enough mechanical energy to keep accurate time for the next 100 centuries, thanks to a gear mechanism and 10,000 pounds of hanging man-made stones. A solar alignment mechanism ensures the clock keeps correct time based on the alignment of the sun. However, if the clock is to sound a chime every year, humans (at least two or three) will need to make the pilgrimage to the clock to wind up the 10,000 pound weight.

The physical scale, timeframe of the project and forward-thinking engineering are astounding and they leave me in awe. This is absolutely a place I want to visit and participate in during my lifetime. The 10,000 Year Clock is our current civilization's mark on the future; it's our Pyramids of Giza, our Colosseum, our Great Wall of China.

2) Wikipedia's Timeline of the Far Future

While reaching about the 10,000 Year Clock, I stumbled across a Wikipedia page that summarized events that physicists, geologists and astronomists theorize will occur anytime between 10,000 years in the future and 1 trillion years in the future - and beyond.

For instance:

In 50,000 years, Niagara Falls will have eroded away the 20 miles of land to Lake Erie and will cease to exist. Also, the earth is projected to go into another natural ice age at this point, if humans don't have an effect on the atmosphere (which we know to be incorrect).

In 500,000 years, odds are sound that the earth will have been impacted by a meteorite of roughly 1km in diameter.

In 11 million (11,000,000) years, the moon Phobos will collide with the surface of Mars.

In 5.4 billion (5,400,000,000) years, the sun will become a red giant. This will destroy Mercury, Venus and possibly Earth (although it is certain that if Earth isn't destroyed, it will certainly not be habitable by this point).

In 50 billion (50,000,000,000) years, the Moon and the Earth (assuming they still exist in their present states) will become tidelocked, with each only showing one face to the other.

In 10^1500 (10 to the power of 1500 - this is a 1 with 1,500 zeros following it) years, all matter in the known universe will have decayed to the element Iron-56 (assuming proton decay doesn't exist, which we don't know yet).

When you examine our individual lives on the universe's grand scale of time, we wink in and out of existence so fast that ultimately we have no effect whatsoever on the universe's final fate. If you combine the last 40,000 years of human history with the next 40,000 (and however far we make it into the future), humanity will still have no effect on the universe. Absolutely incredible and unbelievable.

I don't find this the least bit depressing - in fact, it fills me with a sense of awe and wonder. We exist thanks to a series of extremely unlikely cosmic coincidences and I think it's a wonderful way to think about life: we're here, let's fill our lives with things we love and enjoy it while it lasts.
