Some interesting documentaries

Here are seven interesting documentary-type videos found on YouTube:

You’ve probably heard that Geek Squad technicians snoop around on customers’ hard drives and copy photos and other files for their own use. But have you also heard that they overcharge ridiculously for simple little repairs? Have a look below:

The metro bridge over the river Tyne at Newcastle, UK, was recently outfitted with LED lights that are programmed to never shine in the same sequence. The result is a mesmerizing light show that goes on and on:

Bill Crosby did a documentary in 1968 called “A Boy Like Me”, where he pointed out racial inequalities between black and white children. But he did it in such a poignant way that it’s really, really hard to miss the point. Watch this segment in its entirety, it’s only 3:28 minutes long.

The Falkirk Wheel is an advanced bridge for boats. It connects two bodies of water that are separated by a great height in a very interesting way:

Whether you may or may not agree with this first part of the documentary entitled “The Great Global Warming Swindle” (the other parts can be found on YouTube as well), I think you’ll realize it raises some interesting and valid points. I watched the entire documentary, and if you’ve got the time, I would encourage you to do the same.

The next video is pretty geeky in its approach, but it was made to demonstrate how IT security works for non-techies, and it does a great job of it. It’s entertaining, so you won’t get bored, either.

This last video is controversial, and I don’t know what to make of it. It’s actual news footage aired immediately after the crash of United Flight 93. It shows the crash site and surrounding areas, but the strange thing is that the place looks very much unlike a plane crash site. There are no large pieces of fuselage, no bodies, nothing — just a small hole in the ground, and that’s what makes it unusual. It just doesn’t look like a plane crashed there at all.

A weekend in Manhattan

Light up the nights

Ligia and I spent this past weekend in Manhattan, and got home around 1 am last night, completely exhausted. Was it fun? Yes. Was it worth it? Yes. Are we still tired? Yes.

The trip out on Friday morning wasn’t bad at all. The traffic was decent all the way through, including the Lincoln Tunnel. Even the Manhattan traffic was bearable, except for Times Square. We stayed at the Algonquin Hotel, which is about a half block up from 44th St and 5th Ave, and we loved it. It’s a small, cozy, quiet hotel with a rich history. It has also undergone recent and extensive remodeling, and it looks great, inside and out. I got a chance to compare it with the Waldorf-Astoria, where my parents stayed, and I’ll take the Algonquin any day. The Waldorf is huge — too big for me — and it’s crowded. Sure, it’s very nice, and it’s on ritzy Park Avenue as well, but still, I prefer smaller, quieter hotels like the Algonquin, where I can get to know the faces of the people who work there.

If you’re in town, do try to eat at the Algonquin. We had breakfast in the Round Table Room. The food was delicious, and the service wonderful. We didn’t get a chance to attend one of the shows at the Oak Room Cabaret, but that’s on our list for the next visit to NYC.

We spent our weekend traipsing about Manhattan, visiting various spots like the Flatiron Building, Empire State Building, Rockefeller Center, Statue of Liberty, Museum of Natural History and tons more. We crammed as much as we could into those short few days, and as a result, I have over 1,500 photos while we’ve both got very tired and aching feet (and legs, and hips, and shoulders, etc.). I can’t wait to go through and start winnowing and post-processing my gigabytes of photographic memories.

A few months ago, I read an article that said New Yorkers are the friendliest people in the States. The article had relied on informal methodology to gauge the friendliness of people in various big cities: strangers were stopped in the streets and asked for directions. I got a chance to test those findings during our trip, and I agree, for the most part. New Yorkers are friendly and helpful. NYC cops are also called “New York’s Finest”, and I agree with that as well. All of the cops we talked to were nice to us. They even smiled frequently, prompting Ligia to wonder what makes them so happy in a city so frenetic, where the pace of life and traffic can be so stressful. We don’t know, but they sure were friendly. Even random people on the street, although a little more stressed, helped us out when we needed directions. Not everyone was nice, though. MTA employees were definitely not friendly. I even had a woman employee at the 72nd St subway station yell at me when I complained that my just-purchased tickets would not open the gates for me. While I’m on that subject, the subway ticket machines need better maintenance. They locked up frequently when purchasing by credit card or ATM card. Many did not accept paper notes, only coins. We were left scrounging for loose cash with a line forming behind us…

Manhattan is a very interesting place. This was my first chance to stay there for more than one night, and as I walked around the town, I got the chance to think and compare. Needless to say, space there is at a premium. Everything is packed tightly, and the only way you can get more space is to build up or down. It’s mind-boggling to think how many tunnels of all sorts traverse the underground. Trains, subways and cars travel underground on multiple levels, while pipes and wires of all sorts and ages, all of them needing maintenance, fill out every nook and cranny of available underground space. It must be a logistical nightmare to keep up the infrastructure of a city so massive, on every scale.

There so little vegetation in the city! Most of the time, we were surrounded by concrete, glass or old, grungy brick and mortar. Parks of all shapes and sizes are a welcome sight. Even the planted bushes on penthouse terraces are a sight for sore eyes, though removed from those on the ground by tens of stories and layers of social and financial hierarchy. It didn’t matter though — I had my trusty 100mm lens, and the thing about tele lenses is that they have no social graces. They will cut through distance of any sort and bring the object down to the photographer. I took many photos of beautiful penthouse terraces — little oases of vegetation in grungy, musty concrete fields.

Here, I complain about urban sprawl and the lack of decent pedestrian accommodations. In Manhattan, I got to see the other side of the coin. There can be no urban sprawl. There are too many pedestrians, and you can’t drive your car. If I lived there, I wonder if I could even keep a car. At the prices they charge for parking, I’m not so sure. To get places, you have to either walk, or go underground and take the subway. When you walk into a building, you have to take the elevator. There are no one-story buildings, unless you count churches. Although it was exciting to walk around and look at the architecture, I felt fenced in. There were no wide open spaces, not even in Central Park. The only place I felt freer was on the boat to and from the Statue of Liberty. There, on the open air deck, with the wind blowing through my hair, looking out at the vast expanse of water, I could breathe easier once more. But to get there, I had to take the metro and walk for some time, not to mention stand in line with a ton of people.

And that’s another thing. People are something. We’re social beings, we need company, but we each have our own level of comfort when it comes to the number of other people we can bear. I, for example, can only take so much of being around a ton of people. After that, I need to be alone, or I start getting headaches and feeling nauseous. Times Square, for all its lively and colorful action, is chock-full of people, all the time. When you step into the place, you’re surrounded by buildings on each side. Strident, flashing colors assail you from all points of view. People rub against you. You step out into the street but cars almost run over you, honking endlessly. Camera flashes go off almost every second. Every breath of air feels charged with a suffocating mix of electricity, yet every cubic inch of air is stale. You draw in more, but to no avail. You’re still fenced in, unable to breathe, and the unstoppable urge to get out of that place grabs you by the head and turns you toward the nearest side street. And so you go, heady and reeling from the indescribable something you’ve just experienced, grateful for every breath of cold, fresh air you can pull down from the tall Manhattan sky.

We left on Sunday evening around 5 pm, and got home around 1 am. It was supposed to be a four-hour trip. But we spent more than 1 hour and a half trying to get out through the Lincoln Tunnel. There was an incredible traffic jam, possibly caused by the 5-borough bike race that had taken place that same day and closed various streets and bridges around the island. All we knew is that we were stuck in traffic in some rundown neighborhood, and it wasn’t fun. To make things worse, the NJ Turnpike was also under construction, and the Delaware Bridge was also under construction. We were finally able to reach constant highway speeds when we entered Maryland, and boy, were we grateful for that!

Last but not least, tolls will possibly cost you more than gas on a trip like this (depending on your car). As soon as we reached Delaware and NJ, we got hit with tolls up the wazoo. I think we paid more than $25 in tolls on our way in, and a little less on our way out. It seemed like there were toll booths every few miles. I couldn’t help comparing the Delaware and New Jersey roads to the Maryland roads. In the states where we paid the most money (NJ, DE), the roads were terrible — potholes, construction, lane closures, pavement not level — yet in MD, where we paid only a couple of dollars to cross through the Chesapeake Bay tunnel, the roads were smooth and very drivable. I’m glad I live in MD.

I’d like to visit NYC again. There were a ton of places I didn’t get the chance to see. And I’d also like to stop in Hoboken. It’s got some nice, tall hills with great vistas of the big city. And let me not forget about this energy plant whose name I forgot, alongside the highway in NJ. Lit up at night, with white smoke coming out of its tall, metallic towers set against the darkening sky, it looked like a strange alien spaceship. I’d love to photograph it.

There are so many beautiful places in the States, and throughout the world. If only I could see and photograph them all! 🙂

Thoughts

Super electricity man

Reuters is running a video on a man named Lechi Vataev, a Chechen refugee currently in Russia. He can channel 220-volt electricity through his body naturally, without damage or convulsions. He doesn’t know why he can do it, or how he came into his powers. After seeing the video, I have to say the fellow is surprisingly un-electrifying for a man with electric super-powers. His current motto: “I feel tired and I have a headache sometimes.” If that’s not enough to get you running to see him, then you’re not alone. At least it’s still pretty cool to watch him light a bulb while holding live wires plugged into an electric outlet.

How To

A quick maintenance operation that will prolong the life of your laptop

I upgraded the RAM in my laptop yesterday, and stumbled onto a really easy maintenance job that will most certainly prolong the life your laptop, and help it run faster, cooler and quieter. It sounds impossible to do all that in one fell swoop, but it’s really easy to do, and it works. I’ll give you a hint: it has to do with your laptop’s cooling.

I realize your laptop is going to be different than mine, so my photos may not help you much when it comes to doing this on your own laptop, but bear with me, the principle is the same, and this simple clean-up job will really help.

What I’m talking about is the laptop’s cooling fan assembly. It’s the fan that cools the processor’s heatsink, and is responsible for keeping the processor below the upper temperature threshold. It’s like your car’s radiator. If it wasn’t working, your car would overheat very fast, wouldn’t it? Same thing here, except your laptop’s “radiator” is prone to getting clogged up with dust – lots of it, too.

After about a year and half of using my laptop mostly on clean tables — not on carpets, or my lap, or on tablecloths, as some of us do [!] — I was very, very surprised to find out how much dust had accumulated on my laptop’s cooling grill. I didn’t even open my laptop in order to inspect it. I just wanted to install some extra RAM, but saw the cooling fan and figured, hey, let me open it up even though it looks clean enough from the outside. Boy, was I in for a shocker! Have a look at this photo to see for yourselves.

You may not think that layer of dust is much, but have a look at a macro photo I took of a piece of it. I used a moist cotton swab to pull off the dust from the grill. Can you see how thick it was? It’s a wonder any air managed to get through!

In case you’re wondering how I removed the cover from the cooling fan, it’s simple. There were four small screws holding it in place. They were each about the size of those screws you find in the frames of your eyeglasses, so you can use the small screwdriver from a frame repair kit. (If you’re a geek like me, you probably have your own mini-screwdriver set.) After using moist cotton swabs to thoroughly clean the grill, I blew through the grill from both sides of the laptop to make sure no dust was stuck inside. I was out of air spray, so I just used my lungs — if you do the same, be careful, don’t inhale the dust, it doesn’t taste good… Then I also wiped the fan blades clean with more moist cotton swabs, after which I used a couple of dry ones to wipe the entire assembly. Have a look at the finished product. Looks pretty good, doesn’t it?

The important thing to remember is that most people can do this at home, and it’s a completely user-serviceable operation. I didn’t have to remove any warranty stickers (although my laptop’s out of warranty anyway). As a matter of fact, I only removed the panel that’s supposed to give me access to the RAM. It’s a big panel, so it really gives me access to a lot more stuff.

If my laptop managed to get that much dust inside after only a year and a half of normal use (on tables and desks), I can’t imagine how much dust there is in other laptops that get used everywhere, and never get cleaned! To me, it’s a miracle that most survive through their projected 3-year lifetimes, and even last beyond that. I have to wonder how much better they’d run if their owners would take the time to clean them out once in a while. My suggestion is that you schedule time to do this cleaning once a year.After I finished, I noticed a difference right away. My laptop is cooler now, and runs much quieter. Before, the fan ran in overdrive most of the time. Now, it only runs at higher speeds when the processor is crunching through difficult operations, which is the way it should be. It also runs a little faster, and it’s more responsive. This also makes sense, because a cooler processor works better. It’s the same principle behind water-cooled processors, which can be overclocked because their temperatures are kept low.

At any rate, I encourage you to open up your laptops and try this for yourselves. But please, make sure they’re turned off, unplugged from any power source, and the batteries are removed before you even think of opening them up. Also, ground yourselves before you touch the circuits. You don’t want to short anything inside with any static electricity you might generate.

The new Tesla electric is a screamer

You may or may not have heard about Tesla Motors – if you haven’t, you’ll soon get an earful, and not just from me. There are plenty of other people (Wired News, Wired’s Autopia, Jalopnik, LA Weekly, New York Times, USA Today, LA Times, SF Gate, Washington Post, CBS Evening News, American Public Media’s Marketplace, CNET News, Newsweek) singing the praises of this amazing electric sports car. Here are just a few highlights:

  • 100% electric
  • 0 to 60 mph in about 4 seconds
  • 250 miles per charge
  • Equivalent consumption: 135 mpg
  • Gorgeous styling, amazing responsiveness
  • Truly innovative
  • Rule-breaker
  • Have a look at the tech specs for the other details

Tesla Motors just held a launch party for this amazing car – in CA, where it is based and funded by Silicon Valley millionaires. The event was invitation-only: selected potential buyers and journalists got the special invites, and each of them got chauffered around in the hot little roadster.

With all the excitement surrounding it, it’s easy to lose sight of the fact that it’s amazingly energy efficient given its capabilities. Yes, you read correctly above: its equivalent consumption (in miles per gallon) at the current cost of electricity is 135 mpg. It costs about a cent per mile to drive!

If you want to see it in action, CBS News has a video posted alongside the article right here. It also features the Governator – Arnold himself – in the passenger seat, getting a really fast test drive around the hangar where the launch party took place.

Of course, there are also tons of photos available. I posted a few below, and there are a ton more on the Tesla site.
