Windows 7 + TrueCrypt 7.1a and Debian wheezy + encryption dual-boot with GRUB2

Getting Windows 7 (or Windows 8 or Windows Vista) with TrueCrypt to play nicely with GRUB2 is quite a chore. Although, after 2 days of fighting, I finally found a simple solution, thanks to the README file that comes with grub2tc. Unfortunately, grub2tc didn’t actually work for me, but their docs did!

Here’s the step-by-step to make it all work:

  1. Install Windows. In my case, this meant running the restore CD that came with my computer.
  2. Install TrueCrypt, and encrypt your system drive. Be sure to encrypt only the System drive not the entire disk!

    Be sure to copy the TrueCrypt Rescue CD image somewhere handy. I used a USB stick, but you could burn it to an actual CD just as well. But you will need this later for this procedure.

  3. Install Linux. I choose Debian, but these instructions ought to work fine with Ubuntu, or practically any other variation of Linux. If you’re doing disk encryption (and I’m sure you are if you’re reading this), be sure to create a small (~500mb should be fine) /boot partition that is not encrypted. Then configure the rest of your disk with encryption, LVM, whatever. When I had finished this step, my disk layout looked like this (from the Linux standpoint):
    • /dev/sda1 – Windows 7 Boot partition
    • /dev/sda2 – Windows 7
    • /dev/sda3 – Linux /boot
    • /dev/sda4 – Encrypted Linux volume, mapped to /dev/dm-0
    • /dev/dm-0 – LVM Physical volume
    • /dev/mapper/vg0-root – Linux / partition
    • /dev/mapper/vg0-swap – Linux swap space

    Note that it is important that your swap space is encrypted. Otherwise an attacker may be able to read passwords or other private info from the swap partition–especially if they gain access to your system while it is hybernated (suspended to disk).

    When you install Linux, be sure to install GRUB2, and install it to the MBR. Many tutorials for getting GRUB2 to work with TrueCrypt say not to do this, and instead to install to your boot partition (/dev/sda3 in this case). I had absolutely no luck with these tutorials. If one of them works for you, great. But then you wouldn’t be reading this. So, go ahead and install to the MBR for now. This wll overwrite the TrueCrypt boot loader, but we’ll remedy that shortly.

  4. Configure GRUB2 to boot TrueCrypt. This is the magic you came for. The procedure, which I borrowed pretty much exactly from the grub2tc README is to:

    1. Install syslinux
      For Debian/Ubuntu:

      aptitude install syslinux

    2. Copy ‘memdisk’ file into place for use by GRUB2
      Again, for Debian/Ubuntu. For other distributions, the installed location of the ‘memdisk’ file may be different. (Hint: use ‘find’ or ‘locate’ to find it):

      cp /usr/lib/syslinux/memdisk /boot/

    3. Copy TrueCrypt rescue ISO into place
      If you saved the TrueCrypt Rescue ISO to a USB stick, you just need to copy the file (called TrueCrypt Rescue Disk.iso by default) to /boot/truecrypt-rescue-disk.iso. For example (as root):

      mount /dev/sdb1 /mnt
      cp /mnt/TrueCrypt\ Rescue\ Disk.iso /boot/truecrypt-rescue-disk.iso

      Or if you burned the image straight to a CD, you can accomplish the same thing with dd (again as root, with the CD in the drive):

      dd if=/dev/cdrom of=/boot/truecrypt-rescue-disk.iso

    4. Determine the UUID of your boot partition
      You can read this from /etc/fstab, or with the following command (substitute the proper device name for your boot partition):

      blkid /dev/sda3

      The output should look something like this:

      /dev/sda3: UUID="12345678-1234-1234-1234567890"

      Use that UUID in the next step.

    5. Configure GRUB2 to load TrueCrypt using Syslinux
      For Debian/Ubuntu, the easiest way is to edit the /etc/grub.d/40_custom file. The exact file you edit may vary for other distributions. Add this to the end:

      menuentry "TrueCrypt ISO boot" {
         insmod part_msdos
         insmod fat
         insmod ext2
         insmod search_fs_uuid
         search --fs-uuid --no-floppy --set=boot [UUID without quotes]
         linux16 ($boot)/memdisk iso raw
         initrd16 ($boot)/truecrypt-rescue-disk.iso
      }

    6. Tell GRUB2 to use the new configuration
      Without this step, the configuration that GRUB2 actually reads is never updated, so your changes won’t take effect. On Debian/Ubuntu, simply run the following command:

      update-grub

      It will give a short summary of output. If there are no errors, you should be set to go!

  5. Test it
    Reboot the system. Your GRUB2 menu should now have a new “TrueCrypt ISO boot” option. If you select this option, you will see the TrueCrypt Rescue CD prompt, asking for a password. Enter the password and hit ENTER, and you should be booted into your Windows environment.

The only drawback I’m aware of for this boot method is that you see the TrueCrypt Rescue menu every time you boot into Windows. It might be slightly nicer to see the standard TrueCrypt menu (the one that doesn’t show the option to press [F8] for rescue options). But that doesn’t really bother me in the least. Plus, it might come in handy some day if I need to decrypt my Windows partition, and don’t have my rescue disk handy.

If you come across any problems with this procedure, please feel free to contact me. I can’t promise to help, but I am more than happy to update my documentation to help future visitors.

My Travel Bucket List

I love to travel. Although so far, my travel has been mostly confined to the U.S. and Mexico, with only a short visit to each of Canada, Guatemala, and India. I’m preparing to embark on a long-term journey around the world. Here I intend to document my Travel “bucket list”–the places I want to see before I die. These are not necessarily listed in any particular order, and the list will grow as I hear of new and interesting places or things to see. And as I mark them off my list, I will try to write about each experience in its own article.

The list:

  • Montecristi, Ecuador

    Where all of the finest quality Panama Hats in the world are hand-woven. And perhaps more importantly, where my own Panama Hat was woven. I bought mine from Brent Black. Learn more than you ever wanted to know about Panama Hats, their history, how they are made… and why I want to visit Montecristi, at his Hat Lore & Tales page.

  • Jon Bon Jovi Soul Kitchen — Red Bank, NJ

    I’m not a big Bon Jovi fan… but I do love good food. And I like the clever concept of JBJ’s pay-what-you-can Soul Kitchen restaurant, as a community service.

  • Capetown, South Africa

    I have a dear friend who lives in Capetown. She has invited me to come visit her family, and see her country. We met two years ago when I was living in Guadalajara, Mexico, and I had the pleasure of showing her my home town of Wichita, Kansas, in the summer of 2011. Now she owes me the favor!

  • Cancún, México

    I really hate tourist traps. So this is a bit of an unlikely location to put on my list. I have been to Puerto Vallarta, México many times, and I really don’t like that place. I don’t like the types of tourists it attracts–right white folks with nothing better to do–and I don’t like the kind of Mexicans it attracts–vendors who are all to eager to take advantage of rich white folks with nothing better to do. But, Cancún is said to be one of the most beautiful beaches in the world. So I’ll go, if only for that. There are also a number of near by places I do want to visit, so Cancún will make for a good homebase/airport while visiting surrounding attractions, such as…

  • Chichen Itza

    Only about a two hours’ drive west of Cancún, Chichen Itza is probably the most famous Mayan site in the world; and one I have not yet seen! I always enjoy visiting historic locations, as well as prehistoric ones. This will be a fun experience–even if it is a tourist trap.

  • Acapulco, Guerrero, México

    I don’t know why this is on my list… it just sounds like a fun place to go. And it’s always nice to see a new beach! I’ve also made a few friends over the Internet from Acapulco, so I’ll have someone to meet and grab dinner with.

  • Zijuatanejo, Guerrero, México

    I first learned of this city in one of my favorite movies. It’s probably one of your favorite movies, too, as I have yet to meet anyone who has seen it, but not loved it. The final scene of The Shawshank Redemption shows Red walking up the beach to meet Andy restoring an old boat–realizing his dream come true. Well, I don’t expect to meet Andy Dufresne there, running his hotel (if he were real, he would be long since dead by now!). But I still have a lingering interest to go see this small town, which Stephen King thought was worthy of mention in his story (I don’t actually know if Stephen King mentioned it in the novel version, as I haven’t read the novel–perhaps I should).

Do you know of any other must-see places I should add to my list? Leave a comment below and let me know!

Some questions to ask yourself before voting for or against fluoride next week

This is a letter I sent to a number of my personal friends, employing them to consider how they will vote on the fluoride issue in Wichita next week.

As you probably know, I work in spam prevention, so I am very sensitive to sending bulk e-mails. I debated whether to send this one, but ultimately I decided it was a necessary evil. I hope you will forgive me.

I am only sending this to people I know, and because I believe this issue deserves your consideration, if only for a few minutes, as I think this is one of the rare cases where your vote and my vote has such clear-cut, moral implications! Voting NO on fluoride, if it is as beneficial and safe as claimed, would be immoral, as it would be depriving thousands of an inexpensive benefit! Likewise, voting YES on fluoride, if it is as risky as the opponents claim, would also be immoral, as it will be inadvertently harming people! This is not a simple matter of one opinion versus another–it’s an important moral issue. One I hope you are willing to ponder for just a few moments by reading this entire message. It won’t take long, I promise.

While political discussions often get heated, and I therefore try to exclude myself from them whenever possible, I believe the issue of water fluoridation is quite a separate thing. This is quite a simple issue, that has the possibility for a clear, scientific, non-ambiguous answer. The question every voter ought to be asking is simple:

  1. Is water fluoridation the best way to fight tooth decay?
  2. Is water fluoridation safe?

Both of these questions ought to have simple, clear, and uncontroversial answers, as provided by researchers. There are no nuances, as there are with other political issues, about whether candidate X’s policies are better than candidate Y’s policies, when you consider the complications of the Chinese socio-economic structure… or whatever.

There are two simple Yes-or-No questions to be answered.

After you have read the rest of this message, please take a moment to watch this short YouTube video–regardless of how you answer the questions below. I suspect the information in this video will change some of your answers!

Wichitans for Healthy Teeth offers the endorsements of over 500 local doctors, dentists, and other medical professionals, as well as endorsements from the ADA, CDC, and other national-level organizations, who all say water fluoridation is both safe and effective. This should be a clear win, and convince you to vote YES to fluoride!

HOWEVER, opponents to water fluoridation, such as the Fluoride Action Network make some interesting counter claims. They say “endorsements do not equal science” and that the endorsements from large national organizations, are affected by lobbyists for big businesses, aka “special interests.” They say there are 34 studies that show fluoride, even at very low levels, like those we would add to Wichita’s water, can decrease IQ in children. They say there are thousands of other studies that link fluoride to other possible health effects, such as arthritis, obesity, bone fractures, cancer, and, even INCREASED tooth decay–all at low concentrations, such as would be added to Wichita’s water.

Why is this issue, that should be so easy, and so non-controversial, suddenly so controversial?

To satisfactorily answer this question is not easy, because it actually does involve politics–not just science. And I suspect that you, like the majority of Wichitans, are not interested in taking the time necessary to fully research the issue.

The proponents of fluoridation, like Wichitans for Healthy Teeth, accuse the opponents of “junk science,” and ignoring real studies. They claim there are over 3000 studies on their side.

The opponents repeatedly ask the proponents to cite their 3000 studies. The opponents repeatedly ask the proponents where their science is wrong.

The proponents play cat-and-mouse like the best politicians. Does that mean they’re wrong? No. But it ought to raise a red flag.

I’m not asking you to do a ton of research. I’m also not asking you to take my word for it that water fluoridation is harmful, bad, evil, ugly, unscientific, or any of that.

What I am asking you to do is to be honest with yourself before you vote, and answer a few simple questions, to your own satisfaction:

  1. Are you absolutely confident that fluoride will not cause harm to ANYONE–even those with fluoride allergies?

    To vote YES without answering this question “YES” would be immoral; especially for any doctor who has taken the Hippocratic Oath.

  2. Are you confident that fluoride is the cheapest way to reduce tooth decay?

    To vote YES without answering this question “yes” is wasteful. If we have a cheaper way of solving the problem, why spend more?

  3. Are you confident it is ethical to add fluoride to public water, when many people don’t want it?

    To vote YES without answering this question “yes” is unethical, and a violation of your neighbor’s rights.

  4. One side of the debate is peddling misinformation. Are you absolutely convinced that the ADA, CDC, and related organizations, influenced by multi-billion dollar corporations, and with millions, if not billions, of dollars to lose, and a decades-old reputation to lose, are the ones with the least motive to distort the truth?

    To vote YES without answering this question “yes” is simply foolish and naive.

Please consider these three important questions carefully. If you cannot, with absolute confidence, say “YES” to all three questions, I urge you not to vote yes on November 6. However, that doesn’t mean you need to vote NO, either. Abstaining is a valid option!

I would not ask anyone to vote NO if they don’t believe fluoride is bad. But I also employ you not to vote YES unless you are absolutely sure that fluoride is completely safe, and medically and economically effective!

I thank you for taking the time to read this, and watch the video. I hope you agree it has not been time wasted.

– Jonathan

Super-easy Whole Wheat pancakes

About a week ago, I was at home hungry, and with a nearly empty kitchen. “What can I make that doesn’t require any ingredients?” I thought.

I googled for some whole wheat pancake recipes, as I had a big bag of whole wheat flour, and came up with a super easy, super tasty whole wheat pancake recipe. Although the original recipe called for baking powder, which I didn’t have. So I did some searching for alternatives, and learned a little chemistry at the same time, and came up with what is undoubtedly a better recipe. And it’s so easy, I don’t understand why anyone would ever bother using a pancake mix!

I also cut the recipe in half, as I was only cooking for myself, which which makes 4-6 pancakes.

Ingredients

  • 1 cup whole wheat flour
  • ½ tsp baking soda
  • ¼ tsp salt
  • 1 cup buttermilk, yogurt, or sour milk
  • 1 egg
  • 1 tsp vanilla

Directions

  1. Heat a skillet or griddle over medium heat
  2. Mix the dry ingredients in a mixing bowl
  3. Add the wet ingredients and mix until batter is desired thickness. Add milk to batter*, 1-2 tablespoons at a time (up to about 1/3 cup max) until batter is barely runny.
  4. Add aprox. ½ tablespoon butter to hot pan/griddle, and allow to melt. Pour approx. ¼ cup pancake batter into pan/griddle over melted butter.
  5. Let cook until bubbles form on top of pancake, then flip and cook until done.

Best served with crunchy peanut butter and real maple syrup! Although you are permitted to disagree on this point.

*You may or may not need to add extra milk here, depending on the thickness of your sour milk product. When using yogurt, you may need to add additional milk, for instance, as yogurt produces slightly less runny batter.

In search of the perfect Laptop Daypack

MEI Voyageur Travel PackI like to travel. And I already own the perfect travel pack. It’s the MEI Voyageur travel pack (US$136 direct from the manufacturer). MEI essentially invented the travel pack (a combo duffel bag, suit case, and back pack all in one). It’s perfect for a light traveler, such as myself, for a number of reasons I won’t really go into here. My only regret with buying this pack is that I bought the green one. Why? Since buying the pack, I’ve learned that some countries have forbidden green luggage, as it appears “militaristic.” Wow. Really? Anyway, I’ll probably never visit such a country. But if I had it to do over again, I’d buy black, or blue, or some other color that would have less chance of being a limiting factor.

Anyway, on to what I really care about today… Although I love this travel pack, I need a daypack to go with it. What’s a daypack? I’m sure many of you know, but for the uninitiated (like I was, 6 months ago), a daypack is used when you leave your hotel. You’ll leave all your luggage in your hotel room (or at your Couch Surfing Host’s house), and hit the town with your much smaller, and lighter daypack, which will carry only your essentials. Sun screen, camera, cell phone, money, maps, a book or e-book reader, snacks, water, bathing suit, dancing shoes, etc.

A daypack is also great when you’re traveling by air or bus, and are required to check your main bag at the gate. You can simply grab your daypack (which ought to be stowed in your main travel pack), re-close the travel pack to check it. Then you won’t be left with your essentials when forced to check a bag.

Well, there are many popular daypacks. Many hiking luggage sets even come with detachable daypacks, such as the MEI Trekker I and II. But I don’t want a detachable daypack. I want one to go inside my existing travel pack. I also want one large enough to carry my laptop. Therein lies my problem.

Most bags marketed as daypacks are too small to carry my laptop. And most bags large enough for my laptop are too small to fit (practically) in my travel pack.

So, this is where I ask for your help. Please let me know what kind of backpack you use for your laptop! Here are the criteria it must meet to qualify as the “perfect daypack” for my purposes:

  • It must hold my laptop, with dimensions of 13.5″x9″x1″ (34cmx23cmx2.5cm)
  • It must fit in my REI Voyageur travel pack, with internal dimensions of (roughly) 20″x13″x8″ (51cmx33cmx20cm)
  • It must be a backpack! That means it has straps to go over my shoulders. No hand bags.
  • It must be lightweight. 2.5lb (1.25kg) as an absolute upper limit, but the smallest I can find that will fit my needs is what I want.
  • It must be durable. I’ll be using this thing a lot! Even when I’m not traveling, this will be my primary laptop carrying case.
  • Ideally, it will have a padded sleeve or area to protect my laptop
  • It must have room for additional accessories, such as:
    • A bluetooth or USB wireless mouse
    • Bluetooth or USB headphones/microphone
    • Computer charger, cell phone, cell phone charger, etc
    • Sleeping mask and ear plugs (for those times when I’m forced to check my larger bag on long bus trips)
    • A small amount of nuts or dried fruit
    • A book or Amazon Kindle
    • A safe and convenient place to store maps, airline tickets, or other papers I accumulate while traveling
    • Ideally, a place to store a water bottle on the outside of the bag, for easy access

What have you used, or seen, that might fit the bill for me?

Do you support Chick-Fil-A?

Chik-Fil-A president Dan Cathy recently made the news when he came out as opposed to same-sex marriage. This has all kinds of people upset. Gay-rights activists are calling for protests and boycotts against Chik-Fil-A, for being hateful. Many Christian groups are calling to openly support Chik-Fil-A and their freedom of speech.

But both sides are really missing what, for me, is the real issue:

Chik-Fil-A sells crappy food!

I know this makes me a minority. It might even make me un-American (and if that doesn’t, the fact that I think the latest Batman movie sucks surely does).

And this isn’t just a way to side-step the issue of freedom of speech or gay rights.

It’s a way to side-step all kinds of nasty social issues.

I don’t have to decide whether KFC is intentionally sterilizing African American men. I don’t eat there, either, because their food is gross.

I don’t have to decide if I support McDonald’s environmental decision to use Styrofoam instead of paper, to save trees. I can’t stand their food.

Fast food just sucks. Period. And I boycott all of it.

“Okay, okay. But you’re not getting off that easy,” you may say. “What if some other sort of business that you do patronize came out opposed to gay marriage, would you boycott them?” Well, that’s a fair question. But of course, it’s none of your business. And it’s none of my business why you do or don’t choose to shop at Chik-Fil-A.

The United States of America constitution guarantees something called “freedom of speech,” which gives fast food chain presidents the right to say whatever silly things they want. And it gives you the right to respond by saying whatever silly things you want. It also gives me the right to say the silly things in this article.

What the constitution does not guarantee is freedom from insult, when someone else exercising their freedom of speech says something you don’t like, or that you disagree with. And it doesn’t not guarantee freedom from ridicule when you say something silly.

Bottom line? Boycott them if you want. Post stupid Facebook status updates about your boycott if you want. Or support them if you want, and post stupid Facebook status updates about that. But when you get criticized by your Facebook friends who disagree with you, don’t be surprised.

I think a better solution for those who disagree with Chik-Fil-A would be to quietly boycott Chik-Fil-A, and the thousands of other companies that oppose gay marriage. This would be a more tolerant protest. And tolerance is the key, right?

And for those of you who support Chik-Fil-A, by all means, continue shopping there, but do so quietly. Don’t blabber all over the Internet about how “anti-gay” you are. Spend that effort telling everyone how much you love them, as a Christian should.

Is this issue really worth making enemies and losing friends, over? Taking any stronger stand than just voting with your dollars, only polarizes your opposition (regardless of which side you’re on).

Both sides claim the moral high ground.  So step up, and behave more morally!

If you support gay rights, be more tolerant of those who don’t (as long as you’re preaching tolerance, you don’t get to choose to whom you will be intolerant). If you’re a Christian who opposes gay rights, be a better Christian (if you claim to follow Christ, then you don’t get to choose whom not to love), and extend some charity to those you disagree with.

Then go home and make a sandwich. Out of real food.

The Fluoride Coverup

This article is part 2 in my series on fluoride. See part 1 here.

There is undeniable evidence that both the U.S. Government, and the U.S. Aluminum and related manufacturing industries have been attempting, since the 1940s, and more recently, the U.S. Dental industry, to cover up data about the potentially harmful effects of fluoride.

This article is an attempt to answer the following questions:

  • Is there evidence of a coverup to hide potential dangers of fluoride from the public?
  • If there is a coverup, what is the motive?

This document is not intended to directly address the following questions, although it does touch on some of these topics tangentially.

  • Is fluoride effective at preventing tooth decay?
  • Is fluoride safe?

Fluoride made its first big splash in the public arena in the U.S. during World War II as the war effort ramped up production of many products that used fluoride in their manufacture. Such products included steel, aluminum, various chemicals, such as fertilizers, and, the atomic bomb. Companies involved in these manufacturing processes were becoming increasingly concerned by the effects of fluoride on its workers and the public near its plants, as fluoride was released, primarily in the form of gas from smoke stacks, and was being breathed by thousands of people.

Already by the early 1950s, but continuing heavily into the 1980s, many lawsuits were brought against industry and the U.S. government for fluoride-related pollution and health problems. In 1983, Dr. Leonard Weistein of Cornell University said that “certainly, there has been more litigation on alleged damage to agriculture by fluoride than all other pollutants combined.”1

At this time, fluoride was considered the worst industrial pollutant in history, and had lead to many lawsuits against industry.

And as early as 1969 an article published in The Peninsula Observer, said “fluoride was responsible for more damage claims against industry than all twenty of the [other nationally monitored air pollutants] combined.”2 The next year, a report by the USDA said that “airborne fluorides have caused more worldwide damage to domestic animals than any other air pollutant.”1

One stated goal of these companies, often working together, in sometimes formal coalitions, such as the Fluorine Lawyers Committee3, was to find evidence that fluoride was not causing health problems, or the worst of the health problems. In many cases, the organizations funding the research were instructing researchers to hide or understate evidence of fluoride’s dangers. In the 1990s, an investigation by the Clinton administration, looking into allegations of involuntary medical experiments on humans during WWII, found a memo from the Atomic Energy Commission to researchers investigating fluoride, that stated:

“Information which would invite or tend to encourage claims against the Atomic Energy Commission or its contractor such portions of articles to be published should be reworded or deleted.”4

The very first suggestion that drinking water ought to be fluoridated was made by Gerald Cox of the Mellon Institute, after being asked by ALCOA (Aluminum Company of America) to investigate any dental connection to fluoride.5 Industry, increasingly interested in painting a pretty face on the fluoride problem, fell behind support for the idea of using fluoride to combat tooth decay, and water fluoridation.

Although the evidence that fluoride helped teeth was not particularly strong, a concerted effort was made to make it look as though it did by many of the parties involved. An early study, published in the 1948 issue of the Journal of the American Dental Association, which was “based on work performed … for the Manhattan Project” reported that Manhattan Project workers exposed to fluoride had fewer cavities than workers unexposed to fluoride. Later, a secret, uncensored version of the report was found, which reveald that most of the men in the study had few or no teeth!6

Many of the key players, both personnel, and organizations, involved in the early fluoride research also have tainted track records. Two examples (there are many others):

  • Harold Hodge, the head of the United States Atomic Energy Commission’s (AEC) Division of Pharmacology and Toxicology for the Manhattan Project, who was one of the early proponents of water fluoridation, claiming it was absolutely safe, was responsible for many experiments during the cold war, which involved injecting unsuspecting patients with uranium and plutonium.7
  • The Mellon Institute, which made the original suggestion for public water fluoridation, had also defended asbestos for decades before it was finally removed from insullation.8,9

Since then, other studies have been burried or obscured by proponents of fluoridation. Two notable examples:

  • In 1994, Phyllis Mullenix, Ph.D. of the Forsyth Institute completed research on lab rats that showed that fluoride, at the levels roughly equivalent to those permitted in public water fluoridation programs, was a potent neurotoxin. Four days after her study was accepted for publishing by the Journal of Neurotoxicology and Teratology, she was fired from Forsyth.10,11
  • Elise Bassin’s 2001 PhD dissertation at Harvard showed that boys under the age of 20 who drank fluoridated water had an increased risk of osteosarcoma, a relatively rare bone cancer that typically occurs in boys, and is often fatal.12,13 However, Chester Douglass, Bassin’s supervising professor, and consultant to Colgate, claims that her findings are invalid, and has been investigated by U.S. federal investigators from the National Institute of Environmental Health Sciences.14,15

Whatever the full and true story of fluoride, it is quite apparent that powerful forces do not want fluoride to get any negative press! And the reasons appear to be, quite simply, money. By convincing the public that fluoride is good for our teeth, industry has been able to reduce litigation, avoid strict environmental regulations, and has a place to sell some of their otherwise “toxic waste”–to municipalities!

And now that the ADA and other health agencies have been promoting water fluoridation for so long, there’s a big ego factor at play. To reverse course now would mean to admit to having duped the public for over 60 years!

So to answer the questions posed at the outset of this article:

  • Has there been a coverup of the effects of fluoride? YES!
  • What is th emotive? Money. Reduction in litigation, reduction in strict environmental standards. And now, the health industry’s motivation could well be saving face.

For a more in-depth look at these issues, I highly recommend the book The Fluoride Deception by Christopher Bryson. It is an excellent in-depth investigative report, the result of a decade of research, covering over 5 decades of deception by government and industry on the topic of fluoridation. Half of the book is references!

If you’re like 99.9% of the people reading this, you have absolutely no interest in reading a book on this topic. For you, I highly recommend this 28-minute video. It is a documentary interview with the author of the book, and presents the main findings in a concise manner, that will not be boring!

Canon DSLR Lens Recommendation

A good friend and budding photographer, recently asked me what lenses I recommend she buy to go with her new Canon T4i Digital SLR camera. Wow, I didn’t even know the T4i was out yet. I’m the happy owner of the previous generation, T3i.

If you are reading this, and don’t own a Canon camera, fear not. The advice in this article is still applicable to you. I just cannot recommend any specific lenses, because I haven’t used any non-Canon lenses. But you can search your favorite online camera retailer for a lens that will fit your camera, after applying the advice in this article.

I have been looking and looking, but the more I do, the more confusing it becomes for me to pick the right stuff. You sort of know what kind of shots I enjoy taking, so I was wondering if could help me pick the right stuff, please. Nothing crazy expensive, just something that could help me getting nice pictures of buildings, cities and maybe portraits too.

Well, my friend, which lens to get is a tricky question. And it depends a lot on your goals as a photographer. If your goal is to truly learn the art of photography, I would suggest getting a single prime 35mm lens for now. “Prime” means it has no zoom–it’s always stuck at the same focal length. This is a good first lens for someone wanting to learn the art of photography, because it forces you to think much more about every shot you take. It forces you to zoom with your feet, by moving closer to or father from your subject. It’s very easy, especially for a novice, to stand wherever they are, facing a pretty subject, then just adjust their zoom until the subject fits in their field of view. This is a really good way to take a lot of bad, uninspired photographs.

Using a non-zoom lens also forces you to think about angles in a new way. You may see a beautiful tall building, and with a zoom lens, zoom all the way out so the building easily fits in your field of view. With a fixed lens, you may be forced to walk right up next to the building, and take a photo looking up to the top from an angle. You’ll end up with more creative shots that way. Consider the two photographs of the Empire State Building on the right to see an example of how limitations of a zoom lens (and the lack of budget to rent a helicopter) can add to the creativity of a photograph.

The 35mm prime lens I own, and am quite happy with, is the Canon EF 35mm f/2 lens. It’s not the first lens I bought, but it is easily the lens I use the most, even though I own several other prime and zoom lenses.

My first “real” lens (not counting the throw-away quality kit lens that came with my first DSLR) was a Canon EF 50mm f/1.8, which is also an excellent choice if you’re interested in portraits. But for general around-town shooting, or anything indoors (parties, etc), I recommend a 35mm on a crop-sensor camera (don’t worry if you don’t know what crop-sensor means). I have since switched to the higher-quality Canon EF 50mm f/1.4 lens, when my first 50mm broke in half. If you can afford it, I recommend splurging on the higher-quality lens. It’s build quality is definitely worth it, but it also has better optics, and is better in low-light situations. But if you’re on a budget, the cheaper one is also an excellent lens.

When deciding between a 35mm or 50mm prime lens, let me offer these thoughts:

  • If you will be mostly taking posed pictures of people, and outdoors, or in a very large indoor area, get a 50mm prime lens. This is a great lens for portraits, but it is difficult to use in an enclosed space, such as the average home.
  • If you will be mostly taking pictures of small animals, insects, or sporting events, consider a prime 70mm or 100mm lens. This will allow you to take photographs of objects farther away. But it will severely limit your ability for any other type of photography, so this is probably not a good first lens, unless you know without a doubt you only care about distant objects. You can forget taking pictures of birthday parties with this lens
  • For anything else, get a prime lens in the 30mm-35mm range. This will be wide enough to take pictures even in enclosed areas, such as a living room, so you won’t feel crippled by your camera when taking pictures at parties or family gatherings, but you can still use it to take good artistic shots of buildings, flowers, and casual portraits of your friends.

Eventually, you will want to add at least one more lens to your collection. But it is much harder to give good advice on which second lens you ought to buy until you’ve been using a good prime lens for a few months. The reason is that it is a very personal choice, and depends a lot on what types of photographs you enjoy taking, and your artistic style. Every lens (and for that matter, every other photography accessory) you buy should be bought to fill a felt need. Put another way: If you don’t know you need it, you don’t need it.

Let me offer a few example scenarios:

  1. Imagine you’ve been using a 35mm prime lens for a few months, and you’ve been taking all sorts of pictures of everything you love. Buildings, flowers, people, and bunny rabbits. You find that you are reasonably happy with the pictures you take of buildings, flowers, and people, but you can never get good pictures of rabbits, because they either appear too small, or when you get closer to take a good picture, you scare them away. This is sign you need a longer focal length lens (meaning it will make images appear closer). You need the ability to “zoom in” on a rabbit from a long distance, so that you won’t frighten the rabbit when trying to take a photograph.
  2. You’ve been using your 35mm prime lens for a few months, but you’re noticing that you can never get far enough away from some tall buildings to get the photo you really want. This would be a sign that you need a wider-angle lens. Perhaps something in the 10mm-20mm range.
  3. You’re finding that your biggest pain point when taking photographs is that you can’t get good pictures when you’re indoors, because it’s too dark, and the flash makes everyone look flat and boring. It may be time to buy an off-camera flash.

So in a nutshell, I suggest starting with a single, prime lens, to force you to develop your artistic style, and learn to think more creatively. Then, after a few months, or several thousand photos, whichever comes later, evaluate your photography, and decide what is your biggest weakness, and buy a new lens to help fill that gap.

Below are links to three lenses I have used, and can recommend. For a more in-depth look at Canon lenses, I highly recommend the Digital Picture Canon Lens Reviews. They review practically every lens Canon has made, and have good articles for new and expert photographers alike, to help you select a lens that is right for you.

The Fluoride Debate

I was recently asked by a doctor friend of mine to sign a petition in support of adding fluoride to the water supply in Wichita, Kansas, where I live. Having been vaguely aware of a controversy surrounding the practice of water fluoridation, I informed my friend I would have to research the issue before I would be willing to sign such a petition. My goal in researching water fluoridation was to answer three basic questions, which I thought were the crux of the issue:

  • Is water fluoridation safe?
  • Is water fluoridation effective in combating tooth decay?
  • Is water fluoridation the most cost-effective way to combat tooth decay?

To research, I spent a couple hours on Google, looking for evidence for and against the practice of community water fluoridation. The key piece of evidence I found was a report by the World Health Organization (WHO) entitled Fluoride in drinking-water which makes the following basic claims on the practice of community water fluoridation (CWF):

  • Some studies have found possible health risks to fluoride (tooth discoloration (dental fluorosis), cancer, increased bone fractures (skeletal fluorosis), reproductive issues, etc), but followup studies have failed to produce positive links between fluoride and these health issues at the low doses advocated by CWF advocates. Conclusion: fluoride is safe, at the doses used in CWF projects.
  • A certain level of fluoride is associated with decreased tooth decay

This was enough to convince me that water fluoridation was relatively safe, and effective, in the small doses called for by CWF advocates, such that I was willing to sign the petition presented by my friend.

But I don’t see my friend frequently, and as the days went by, I was still a little unnerved by the key factor that the health risks associated with fluoride were acknowledged at “high” doses, and that administering the “optimal fluoride level” seemed rather fragile, when being administered in drinking water–which is not consumed at the same rate by everyone. How could a CWF project ensure that nobody got too high of a dose?

So I began doing additional research, and finally came across some opponents of water fluoridation, whose basic arguments are:

  • Fluoride is a toxic waste product, initially added to tooth paste and public drinking water in the 1940s as a public-relations stunt, to reduce the negative perception of fluoride pollution by industry and government
  • Fluoride is a carcinogen, causing drastic increases in bone cancer, especially in young boys, even at the doses found in CWF projects
  • Fluoride is a neurotoxin in sufficient doses, causing memory problems, ADHD-like symptoms, and possibly reduced IQ in children
  • Fluoride reduces thyroid function, and was even used in treatment of overactive thyroid by doctors in the 1940s
  • Fluoride is responsible for skeletal and dental fluorisis, which makes bones and teeth, respectively, brittle, and susceptible to breaking.
  • There is a coverup by industry and the government, trying to hide the negative effects of fluoride on health
  • It is unethical to “mass-medicate” an entire population. No other drug is prescribed to an entire community in such an uncontrolled fashion.


Some opponents have even made claims that:

  • Water fluoridation is a communist plot
  • Water fluoridation is a plot by the government to intentionally make the public stupid, so they can be controlled. (Claim made in this video from 4:38-5:15)

So it’s obviously pretty easy to dismiss some of the opponents as left-field conspiracy theory kooks.

But what is the truth? If CWF is as dangerous as the opponents claim, where is their evidence? And what is to be made about all the pro-fluoride evidence? If CWF is safe, as the proponents claim, then where are the opponents getting their information? Who has a motive to promote fluoridation if it’s unhealthy? Who has a motive to vilify fluoride if it is healthy?

As I continue my reading on this subject, I will continue to write about my findings here, and in as objective a manner as possible. My only agenda is to determine the truth of the matter.

In the following posts, I intend to address the three questions as the opening of this article, and additionally:

I hope you’ll check back occasionally as I add to this series on the science of community water fluoridation.

“Fancy” green beans with almonds

This is a very simple recipe, but one that I really like, so I figured I’d share it anyway. It’s a personal favorite when served with beef stroganoff, but of course is good any time you want some green beans that aren’t as boring as usual.

The end result is green beans with a pleasant nutty taste, and the lemon juice really compliments the almonds.

Ingredients

  • 1 lb fresh green beans
  • ½ lemon

    or 1-2 tablespoons lemon juice

  • ¼ cup salted butter
  • ½ cup sliced almonds

Directions

  1. Boil or steam fresh green beans as desired. While the green beans are cooking, prepare the almonds:
  2. Melt butter in small saute pan over medium to high heat.
  3. When butter is hot, add juice from half a lemon, or lemon juice to the pan.
  4. Add almonds and stir constantly until almonds are browned.
  5. Place cooked green beans in a serving dish, then pour almonds and butter/lemon juice over the green beans before serving.
