Every flush counts

I just moved into a new place and along with the usual pains of unboxing, cleaning, and organizing, I also have a few energy saving things I must check or fix before I can call myself settled.  The first couple are pretty obvious – replace each light bulb with a compact fluorescent, inspect all the windows and doors for leaks, hang a clothesline, and replace any air filters.  The last is less obvious, but probably the easiest. I convert my normal toilets to ultra-low flush toilets.

The conversion starts with some extra milk jugs, juice containers, or anything denser than water – I used a juice container.

1. Fill the container with water.

Pick an appropriate water bottle

2. Place the container into the tank of the toilet.

3. Enjoy saving water and money.

This will work for any toilet, but is especially helpful for toilets that use more than 1.6 gallons per flush. My previous house had 3 gallon per flush toilets and by using multiple containers, I was able to bring the usage down to 1.5 gallons per flush.  At this residence, I have newer 1.6 gallon per flush toilets and I used a single half-gallon jug to lower that to 1.1 gallons per flush.

I can also report that lowering the toilets usage doesn’t result in clogged toilets.  You might need to experiment a bit to find the right ratio of savings to flushing power, but I personally have had no trouble, even with the toilet only using 1.1 gallons per flush.

Another great thing about this technique – it’s free and allows renters to be more efficient immediately rather than waiting on their landlord.  Give it a shot and happy flushing.

Hold Steady - Almost Killed Me

I’m starting the post with a positive jam (thanks Hold Steady).  This post might be scary to some and I figured you might want the mental reinforcement.  Ever since mobile phones became connected to the Internet, the ability of “the man” to track us has become easier and easier.  Ironically, this power was given freely by most netizens.

It’s not wiretaps, email snooping, or cell phone tracking that give them (and your grandparents) the ability to know what you are doing minute to minute, but instead twitter posts, facebook status updates, yelp/foursquare/gowalla check-ins, and something I wanted to talk about in this post – geolocation.

Geolocation for those unaware, is the adding of real world address or GPS information to a virtual object like a picture or post.  The reason I wanted to call attention to geolocation is that compared to status updates, twitter posts, etc., it often happens unknowingly or accidentally for the average user.  When you post to twitter that you are eating at such and such restaurant, you’re actively telling the world where you are.  When you post/email an interesting photo for your friends to see, you may not realize that you could give out your home address.

This is because newer cameras and most smart phones can now use their built-in GPS units to tag photos with where they were taken, including your home or anywhere you take pictures.  The problem for the average user is that the picture doesn’t appear to hold this information and so there is seemingly nothing to fear.

The location information is there, I promise

For those that know where to look though, it’s quite simple.  I took the picture above with my iPhone this summer while at the Very Large Array and as I will show you, it recorded exactly where I was standing.  Viewing the information involves something called EXIF. You can think of EXIF information as the writing on the back of the photo.  In the past, EXIF information included what type of camera took the picture, when it was taken, what the aperture of the camera was, etc., but now it can also include information like GPS coordinates.

On a Mac, the process involves opening the photo in Preview, viewing the inspector, and going to the GPS tab.  Apple conveniently put a “Locate” button that shows me on Google Maps exactly where the photo was taken.

Screenshot showing GPS information lookup

On Windows, the process almost as simple.  Just right-click the picture and click properties.  Under the “Details” tab if you scroll down, you might see a GPS section like the one pictured.  I should note that this is only for Vista and Windows 7.  Windows XP will not show the GPS section even if the photo contains one.  For XP users you can download a program called KUSO to see this information.

Example using Windows 7

Now that you’ve seen it done, it seems pretty simple. Most people have never opened the “Inspector/Properties” and thus never realized just how much data is there beyond just the picture.

You can relax slightly because common places photos are posted to: facebook, twitpic, and flickr clear out this information automatically.  While they may be removing it from public viewing, they still are able to see this information themselves and they could change their policy about sharing that information at any time, so I still recommend removing the data yourself before uploading.

When using less reputable websites, forums, or emailing attachments is when you are most vulnerable.  In these scenarios, the photo is sent unaltered and thus containing all the EXIF information.  In these cases, you will need to remove the information yourself before sending.

So how do we get rid of this information?  There are many programs, and many operating systems, so I can’t go into all the ways, but I’ll cover a couple very common scenarios for Mac and Windows.

When using iPhoto on a Mac, whenever you export a photo or share a photo, there is a little checkbox for including location information.  Just make sure the it’s unchecked and you are ready.

Exporting in iPhoto

A program called SmallImage for the Mac is another good option if you prefer to remove all EXIF information in addition to the GPS data.

For windows you can download a program called Easy EXIF Delete.  For Adobe Photoshop users, on either OS X or Windows, use the “Save for Web…” command and this will remove any extra data.

There is of course one way to avoid all of this hassle – don’t use the location services of your phone or camera.  I have an iPhone, so I can show you how to disable it on iPhone/iPod Touch devices, but for other manufacturers you’ll need to check with Google or your nearest geek.

Location Settings

On the iPhone, click Settings ->General ->Location Services. Here you can disable all location services at the top, or pick which individual applications are allowed to know where you are.  Find the Camera and slide it to “OFF” and now all your photos will be geolocation free.

This is by no means a comprehensive list, but Google is your friend and I mainly wanted to bring the idea of geolocation to your attention.  There are plenty of good reasons to have your photos geotagged, but knowing when to use it, when not to use it, and how to remove it, will keep this feature from turning into a liability.

Attribution please

I am by no means a professional photographer, but I’m proud of the images I capture.  That’s why I was shocked and irritated when going through website logs to discover that several of the photos I have posted here and other places are being used without my permission on other websites.

Now, this is nothing new, and I suppose I should take it as a backhanded complement, but it’s still irritating.  It’s especially irritating when the particular thief doesn’t even take the time to download the photo and re-upload it to their own servers, thereby wasting my bandwidth.  This laziness does, however, allow me to do certain things for retribution.  When a photo is referenced from another person’s website it means that if I change the photo on my site, it also changes the photo on any site that referenced that photo.

I should note that before changing the photo in the example below, I did try to contact the administrator to get an attribution, but that failed, so I made a slight edit to my photo that affected their homepage.

If you are too lazy to take your own photos, let me offer you some pointers.  If you find something on the Google Image Search or similar services and want to use it, contact the creator.  If that’s too much, after stealing the photo simply give a link showing where you got the photo from.

Example:

Bike in Marfa, TX

Still asking to much?  Stop the Google Image Search and head over to flickr.com and search the Creative Commons photos.  They have a little checkbox for “” and you can take all that your heart desires.

Lesson over…you’re welcome.

Buy local, save local, debt local

Late at night, Meaghan and I sit over cups of coffee and try to solve the world’s problems.  The topics vary greatly.  Recent topics have been healthcare, capital investment in emerging markets, and the implications of treating corporations as individuals.  I’ve come to the realization that late night chats, occasional political status updates, and biannual voting are not a significant enough contribution to my role as citizen in our representative democracy.  The problem is how to affect change and to what policies.

The rhetoric in the US has become so divided that inaction and maintaining the status quo almost sound favorable compared to some of proposed solutions, and yet that isn’t what I want either. We must come to some common ground. Fortunately, I believe there’s one area of life we can start to work together on whether you are a Tea Party supporter or a Socialist – local community prosperity.

For the Right, going local takes power away from centralized government, multinational corporations, and Wall Street fat cats.  For the Left, going local is environmentally sound, anti-corporate, and promotes community.  People and politicians can argue all day long about which policies will stimulate local initiatives, but nothing is preventing people from changing their buying habits other than well-crafted marketing campaigns and a perceived convenience of big box retailers.

Long ago, my father told me that “every dollar spent is a vote.”  It’s a philosophy that I’ve mentioned before, but an idea that has stuck with me and also one I believe is the most powerful in our current “free-market.”  Whether it’s spent on various products, charitable donations, or campaign contributions, these “votes” decide what products, services, and policies the private market and public figures will focus their attention on.

Going local can mean many things.  In recent history the focus has been on where you shop and what you eat.  Those choices are very important, but I want to call attention to an area little talked about – how you purchase.

The average consumer is probably unaware that the switch from using cash to credit has hurt businesses of all kinds greatly. Every swipe of the card deducts anywhere from 2% to 3% of the sale away from the business and to the credit card company and issuing bank. To put that in perspective, if a business does $30,000 in sales for a given month, they are losing up to $900 for the month or $10,800 for the year. That’s money that a lot of small businesses do not have or could use to pay their employees more.

Other countries have passed regulations that have curbed the excessive fees that credit card companies charge.  In the case of Australia, transaction fees have been lowered to 0.5% (a 600% reduction). Of course lobbying congress to fight the credit card companies could take a while, so it might be best to take matters into your own hands.

The most apparent way to do this is always pay in cash. I highly recommend cash because it’s simple and limits your likelihood of going into debt. For many people this is not possible or practical, either for financial reasons or just convenience. A possible compromise exists by switching your national credit and debit cards to a local credit union.

The switch helps mitigate the problem of high transaction fees by keeping money the hands of the local community.  While the transaction fee will still be charged, the majority of the fee goes to the issuing bank and in this case, your credit union.  Rather than the money leaving your community for Wall Street, it goes to your local credit union and is used for loans within the community.

The same is true for the interest you will pay on that debt to the credit card company.  Rather than interest payments bolstering stock values, they will instead be bolstering your local economy.

The whole idea of “going local” is to improve the economy and sustainability of the community you live in, and the more money you can keep in that community, the better it will do.  I am personally in the middle of such a transition and will post more about the pros and cons as I come across them.

There’s more to local credit unions than just changing the way you purchase.  The benefits are several fold and for more information, you can read these articles here and here.
