Proper disposal of old electronic equipment

Frank Gruber of SomewhatFrank.com posted a neat video made by GOOD Magazine to his blog. The video’s enclosed below, and you can also view it directly on YouTube. It documents first hand just how electronic waste is “recycled” in countries like China or India. Besides unmitigated pollution to the air, ground and water, the workers themselves are exposed to serious damage from working at those places.

Please don’t contribute to the problem. Do the right thing. Recycle your electronic waste (old computers, stereos, iPods, printers, etc.) the right way by sending them to companies that will do it right here in the US, in environmentally-safe ways. The major computer manufacturers will either recycle them for free nowadays, or allow you to pre-purchase a shipping label so you can send the computer back to them at the end of its useful lifespan. The average cost to recycle a computer in the US is $30. That’s a small price to pay to ensure that you’re not causing even more damage to the environment that feeds you and keeps you alive.

ISPs to become IT providers for home users?

Bruce Schneier makes a solid point in his recent post entitled “Home Users: A Public Health Problem?”, where he states that computers and computer security are much too complicated for the regular home user. That’s most certainly true. No matter how much you “educate” the average user, they’re still going to mess up. Even if they’re working in IT, that’s no guarantee of know-how. There are so many things you can do in IT these days that an IT guy might not even know what a hard drive or a RAM module looks like. You really have to like working with computers to get the way they work and to be willing to put in the time to learn how to protect and operate them the right way.

But then Schneier says ISPs should become IT providers for the home user. In other words, provide real Help Desk support for software installations, router and firewall settings, anti-spyware and anti-virus software, etc. This sounds good at first until you realize there’s a very small step between that and choosing to mitigate damage to the network by controlling what software users can install and use on their computers. What’s to stop ISPs from requiring that users register their computers on their domain (or doing it automatically as users run their software CDs), then pushing down group policies that enforce their rules?

What’s the alternative? Make computers easier to use! Operating systems and the gadgets that go along with them have to become really easy to use. A certain number of security options have to be enabled by default, and those settings have to able to propagate from the OS down to the gadgets (firewalls, routers, printers, network drives, WiFi devices, etc.) automatically and where applicable. You set it once and it gets set everywhere else. I talked about this in another post of mine, entitled “It’s got to be automated“. Have a look at that as well.

The starting point should be OS X. It’s not the best OS it could be, but it’s a lot easier to use for most everyday tasks than other systems, but even it is hard to figure out for a normal user when it comes to security and special protocols like site hosting, file sharing or FTP, and privileges between users in places like the Shared folder.

We need to do away with arcane file names for user groups in operating systems. Privileges should be much easier to set for files, folders and entire drives. Systems ought to be smart enough to know when we’re trying to share something with the firewall up, and pop up an on-screen wizard to assist us. They should anticipate certain things and guide us through.

I say we need to make all network devices manageable directly through the computer, instead of having to log onto them separately. This goes especially for routers. The computer should know there’s a router on the network, and allow us to manage its settings from the control panel, as we would manage a printer, but make it even easier. It should auto-configure it with medium-level security by default and only ask us to choose a password and be done with it.

The solution lies in making better software and hardware.

Get smart about money in 135 minutes

Two easy steps are involved with this:

  1. Take 90 minutes to watch Dave Ramsey’s video entitled “Dumping Debt“. It was posted to YouTube in 10-minute segments. Here they are: Part 1 – Part 2 – Part 3 – Part 4 – Part 5 – Part 6 – Part 7 – Part 8 – Part 9. This was possibly posted without Mr. Ramsey’s permission, so please consider purchasing the DVD from his web store. (via Get Rich Slowly)
  2. Take 45 minutes to watch Paul Grignon’s video entitled “Money as Debt” on Google Video. Trust me on this. You will be shocked. You will have your eyes opened, and then you’ll realize what makes the world go ’round. (Cristina, thanks for pointing this out to me!)

Since both of these resources were posted online at full length, and I’m not sure if they were posted with or without their authors’ permissions, you’d be smart to watch them now, while they’re still available. I do not endorse use of copyrighted materials without permission — and to be fair, I don’t know that’s the case here — but I did want to share this information with you. If the videos should become unavailable for some reason, then please consider purchasing them. They are worth your time and money.

Finding myself more and more

Imagine this: you’re born with a desire to relate to others, to spend time talking and laughing with good friends who respect you and want to relate to you. But as you grow up, you find your confidence betrayed by false friends, derided by immature ones, or worse, you find yourself fending off unwanted advances from homosexuals who confuse your wish to socialize and relate to them as one human being to another for something else, something disgusting to you.

What do you do? You put up a wall. You become a loner. You choose to call yourself non-social. You make yourself believe you don’t need friends and you don’t need others. Alone, in the dark, you even start getting doubts about your sanity and sexuality, though you know better.

But then, after much prayer, you meet a girl who loves you for who you are. She respects you. She inspires you. She wants to be with you. She becomes your closest confidant, your best friend, the one you always go to for advice, and then, your wife. A dark, brooding veil begins to lift. You start seeing life through a different light. You meet her friends — decent, sociable people who enjoy good company the way God intended it, with laughter and talk and jokes and more laughter and help when you need it.

You begin to grow as a person. You start to make friends on your own now. People begin to discover you for who you really are, and the honest ones tell you that you’re a likable guy after all, that their first impression of you was wrong. All of a sudden, life is better. There’s more hope and joy in it. Friendship starts to take on the meaning you’ve always dreamed about. You find yourself.

This happened to me. I tell you, it feels like a long, dark night is giving way to breaking light. I doubt I’m alone in this. So what I want to say is, don’t lose hope. Hang in there. Pick your friends carefully. Don’t doubt who you really are for a minute. If you persist, you will succeed.

Thank you, Ligia, for making me see the light. It was through you that I grew and found myself. Thank you, and, though you already know it, I love you.

Lens review: Canon EF 24-70mm f/2.8L USM Zoom Lens

The EF 24-70mm f/2.8L USM lens is the professional standard zoom from Canon, and so far the golden standard for sharpness, contrast and bokeh in a zoom lens. Photographers drool over it and swear by it. Its focal range on a full frame sensor makes it very appealing for event photography. It goes from a wide 24mm to an almost portrait-length 70mm to allow for close-ups. It’s also plenty fast for a zoom — f/2.8 — just about the fastest a zoom lens can get these days. (I’d like to see an f/2.0 standard zoom, but I don’t know when that’ll happen, and the cost will probably be fairly high.)

I’m going to talk exclusively about the 24-70mm lens in this review, but if you’re interested, I also wrote a comparison of this lens and the 24-105mm f/4L zoom. You may want to read that as well, in order to get a better idea of how this lens performs.

As you know if you’re a regular reader, I write about how products feel and the results they give me. My reviews aren’t spec-heavy. I give you my honest opinion about a product, and tell you what results I got with it.

With that in mind, the 24-70mm zoom is a good lens. It’s plenty sharp, has plenty of contrast, and the bokeh is great. I liked it. But it’s heavy — really heavy. When you hold it in your hand, it doesn’t feel that heavy, but when it goes on your camera, your wrist really takes a beating, and it feels as if the camera’s body is going to give. This lens is incredibly front-heavy. That means there’s no chance of holding the camera with one hand for long when you use it. On my 5D, it’s really hard to use the lens without a vertical grip, which gives me more finger room. Without the grip, you have to support the lens itself when you take the shots, and then you have to be careful that you don’t grip the focus ring and impede the auto focus from rotating when you press the shutter button. I use a keyboard and mouse all day long, so I realize I may not be the strongest guy around, but I lift weights once or twice a week. Still, I tell you, this lens really took its toll on my wrist joint and finger muscles. It was a real workout. I didn’t expect this kind of weight from a standard zoom. I did expect it from the EF 70-200mm f/2.8L IS USM zoom. If you’re so results-oriented that you’re willing to overlook the weight, great, get it, you’ll love the results.

I mentioned the useful focal range above. Let me illustrate it with a few examples below. At the wide end, you can capture beautiful landscapes… or nice wide angle shots of buildings. At medium range (30-60mm), you can get photos like these. The lens also has a very useful close-focusing range (0.38m), which allows you to get close-ups like you see below.

Let’s talk about low light. This lens has no image stabilization (like the 24-105mm zoom) and that means the maximum aperture of f/2.8 starts to show signs of strain in low light. It means we have to bump up the ISO and make sure the shutter speed stays at or above the focal length, stabilize the camera, and/or use a flash. Like I said in the opening paragraph, this isn’t a fault of the lens — f/2.8 is the fastest aperture for a zoom lens on the market, so that’s just how things are.

I enclosed a few photos taken in low light above. The first was taken inside a piano store, and although there was plenty of fluorescent lighting, I found that it wasn’t quite enough to shoot freely, like I would have done with a faster prime lens. I can’t argue with the sharpness and bokeh though. It’s beautiful.

There’s a second interior photo, where I had to use a speedlite. I used the 580EX II, also from Canon, and bounced it off the white ceiling. The lens does fine with a good speedlite, so that’s no problem.

The last two low light photos were taken in downtown Bethesda at night. For the first, I stabilized the camera with both hands on a balustrade in order to take it. The second photo of a VW Bug was taken handheld from a lower angle.

A lot of photographers use this lens for portraits, so I thought I’d show you a portrait I took with it as well. It’s on my wife’s website, Fun Piano Lessons. The tele end of the focal range is just right for portraits, and the sharpness, contrast and bokeh are great, especially with a wider aperture like the f/4 used in that photo.

All in all, this is a lens that does not disappoint. I expected professional results when I used it, and got them, without a doubt. The only two things that I minded were the weight — in particular its front-heavy distribution — and the lack of image stabilization. But if you were to get this lens and the EF 70-200 mm zoom, you’ll have covered most of the useful focal range you’ll need with just two very versatile lenses. Some food for thought there.
