Cut Your Food Costs With a Stand-Alone Freezer

Kris and I recently bought another side of beef. Well, to be more accurate, we purchased one third of a cow. Every year, we go in with several other families to split an animal. This year, our portion of the purchase comprised:

  • 46 pounds of lean hamburger (in 24 packs)
  • 36-1/8 pounds of roasts (in 10 packs)
  • 31-1/4 pounds of steak (in 20 packs)

We also received 2-1/4 pounds of beef tongue that we're giving to the guys at the box factory. José and Jesus tell me that lengua is delicious, but I'm not willing to prepare it myself. (If they want to make something for me, I'll eat it.)

We received a total of 115-5/8 pounds of beef for $425, which is an average cost of $3.66 per pound. (In December 2006, we paid $300 for 83 pounds of beef, for an average of $3.61 per pound. In November 2007, we paid $277 for 81 pounds of beef, an average of $3.42 per pound.)

The problem is, Kris and I can't eat this much beef. We love it (sorry, vegetarians), and we think we're getting a great deal at this price, but we're not willing to prepare beef more than once a week. This year, we recruited help. We found two other families to split our share. They each gave us $100, and we gave them one-quarter of our load.

This still leaves us with a lot of meat. Fortunately, we have a 20-year-old upright freezer, which we picked up for free from one of Kris' co-workers. This freezer is a godsend. We use it to store our beef, and plenty of other food besides. But whenever I mention the freezer, I get comments asking me how cost-effective it really is. That's a great question. I finally found time to answer it.

Using my Kill-a-Watt electricity meter, I took four readings of the freezer's power consumption.

  • After 47 hours, the freezer had consumed 3.13 kilowatt-hours of electricity (for an average use of 67 watts).
  • After 70.5 hours, it had used 4.73 kWh (67 watts).
  • After 116 hours, it had used 8.07 kWh (70 watts).
  • After 154 hours, it had used 10.69 kWh (69 watts).

For ease of calculation, let's say that our freezer seems to be using an average of 70 watts, or about 1.68 kilowatt-hours per day. That's 613.2 kilowatt-hours per year. Because our electricity costs us 12 cents per kilowatt hour, that's a total cost of just over 20 cents per day. It costs us about $75 a year to run the upright freezer. A newer, more efficient model would no doubt cost even less to operate.

"How do you feel about that cost?" I asked Kris once we'd computed the numbers. "Do you think it's worth it?"

"Totally," she said. "And here's why. Having the freezer gives us flexibility because it lets us stock up on things when prices are good, instead of just when we run out. If I see that butter is on sale, I can stock up."

"That's not all," she said. "Because of the freezer, we're able to buy a lot of things in bulk, which brings the cost per unit down. Like those Costco bags of shredded cheese that I use in soups, quesadillas, tacos and other stuff. I just divide it up into reasonable portions and stick it in the freezer."

"Yeah," I said. "And I guess I'm able to buy several boxes of my favorite Trader Joe's items which means we don't have to make extra trips, which would require more gas and more time shopping."

"Right," said Kris. "Finally, don't forget the most important reason for having a freezer. It lets me preserve a lot of food from our garden. We've been using frozen jam, berries, and pasta sauce all winter. I've already added a batch of strawberry jam and twelve cups of frozen berries from this month's berry crop." I licked my lips at the thought of fresh strawberry jam as Kris continued: "I've never run the numbers, but I don't have to. I'm certain the freezer saves us more than a $6 per month."

For more info about the cost-effectiveness of a stand-alone freezer, check out:

This is the first time I've really used the Kill-a-Watt to help evaluate my financial choices. For my next experiment, I'm going to measure how much electricity Kris' computer and monitor use. How much energy (and money) could we save by turning these off when they're not in use?

Edit: Holy cats. I cannot believe I typoed "freezer" as "feezer" in the title and left it live for eight hours. How mortifying. Please take away my license to blog!

How To Easily Set Up Google Apps on Your Website

 
 

Sent to you by Sparkie via Google Reader:

 
 

via MakeUseOf.com by Mark O'Neill on 7/4/09

The other week I moved my email service over from Yahoo Webhosting to Google Apps.   I finally managed to stop the procrastinating after a year of dithering about and just did it - and I was pleasantly surprised at how easy it was to set up.

This was one of the reasons why I procrastinated so much - I am not much of a technical whiz and I was nervous that I would well and truly cack it up.  Then I would have to go through the embarrassment of asking someone to look at my mess and clean up after me.    Meanwhile, all my incoming emails would be disappearing into a black hole never to be seen again.

But it turned out to be a cinch.   I had the whole thing up and running in 30 minutes and the emails flowed in without a hitch (after being briefly slow at the beginning - but I put that down to the email servers being transferred over and my new Google Apps account being processed.  After a while, email service went back to the normal speed).

In case you have ever wanted to move over to Google Apps but you've been nervous about the set-up, I would like to help you end your apprehension and get you started.  Kudos to Google for making it so easy.

Fill Out The Online Application

If you are a family, private user or non-profit organisation, Google Apps is free to use (businesses can have a trial period and then $50 per year per person).   But for me and probably for most of you, the free "standard edition" is the one to go for.   Go here and fill out the application.

The first step of the application is to enter your domain name (or you can buy a new domain name though Google which automatically sets everything up for you).   You also need to verify that you own the domain or if you are a member of the domain.

Then click "get started" and a standard application form pops up.   Fill it out.

Assuming all of the information is acceptable to Google and you are authorized to set the domain up on Google Apps, you will then be taken to your new dashboard.

The first thing to do is activate your email. You need to specify whether you like the URL Google automatically makes for you. So for example it may have made :

http://mail.googleapps.yourdomain.com

But if you don't like that URL, you can easily change it to something secret such as :

http://mysecretmailbox.yourdomain.com

Now to activate the email.   Go to the email settings page and there are two options - "create user accounts" and "change MX records".   OK, no need to get nervous.   Let's do them one at a time :

Create user accounts

You may have a lot of email addresses for your domain such as info, contact, your name, webmaster and so on.   You need to now input all those email addresses into Google Apps.    Or if you don't feel like typing them all in, you can upload an Excel CSV file with the addresses already in it.   Google Apps will then insert the email addresses into your email settings.

Change MX Records

OK, now the biggie.   The MX records shows which company handles and delivers your emails.   You need to change the records from your old email provider to Google so your emails can be sent to your Apps account.

It's not a problem as Google provides step-by-step instructions for whoever your old email provider is.   Just choose your hosting service from the drop-down list and you will get instant specific instructions on where to go and what to do.

It basically involves locating the MX Records list in your hosting account (Google tells you where it is) and deleting them all (you may want to take a screenshot first in case you need to revert back).   Then in their place, enter the following :

Then save the whole lot. And that's it - email set up!

As I said, it may be a little sluggish at first with emails trickling in slowly but once your Apps account is processed and set up by Google and your MX records get transitioned over, the email will start to come in a lot faster. Just be patient.

If you had your Apps email address already previously set up to forward everything to your old Gmail address, you need to go to the old Gmail address and cancel the forwarding rule.   Otherwise you will end up with two copies of the same email - one in your Gmail account and one in your Apps account.

Next, you can decide if you want to change the destination links for your calendar, Talk app, Documents and Sites (just like you may have changed the URL for your email inbox).   Then activate each service in the settings.

The last thing to do is go to the CNAME settings in your hosting account (again, Google points the way) and you need to enter each URL along with ghs.google.com .  That points everything to the Google servers.   Save everything and you-are-done!   Finito, The End.

All that remains to be done is browse through the settings and customise everything to your liking (for example, you can replace the Google logo witb your own customised logo).

I highly recommend moving over to Google Apps.   It's a nice all-in-one online email, calendar and documents application.  The only grumble I have about it is that you can't import your emails over from a normal Gmail account.  Google doesn't provide any email exporting function so your emails are stuck in the other account - unless you go the long tedious way of downloading the emails to Outlook or Thunderbird and then using an import tool to re-upload them.  We covered one of these tools in the past.    But it is very easy to import your filters and contact book over and I had the email purring along in no time.

Do you have any experience of moving your online presence over to Google Apps?   If so, how did it go for you?   Please do let us know.   If you haven't moved over yet, has this guide persuaded you to give it a go?   Feel free to leave all your questions and comments below.

How To Access Hotmail Email Messages from Your Gmail Account

 
 

Sent to you by Sparkie via Google Reader:

 
 

via MakeUseOf.com by Jack Cola on 7/5/09

If you spend a lot of time on the web, either for leisure or work, you may find yourself having a lot of email accounts. I know I do. I have heaps that I regularly check; work, websites, personal. But I found myself wasting so much time logging in and logging out of Hotmail and Gmail individually just to check my emails. I decided I had to do something.

What I first did, was to download Mozilla Thunderbird. I set up of all my Hotmail and Gmail accounts and it worked very well. But if I was away from my desktop computer for a while, I found I was going back to my old ways. Thankfully, Gmail had a solution.

To simplify the whole process, the answer was to make one of my Gmail accounts my main email account. Then, forward all my emails, including those in my Hotmail email account, to that Gmail account. This way I would be able to access hotmail email from Gmail. However, this is not a simple as opening Hotmail, go to options and click forward. The problem is, Hotmail only allows you to forward emails to the following domains: hotmail.com, msn.com, live.com, or a Windows Live Custom Domain.

how to access hotmail from gmail

Below, I am going to show you how to download Hotmail emails to Gmail.

What you have to do then is go to Gmail –> Settings–> Accounts and there will be an option that allows you to download mail from other accounts.

Type your email address, and then click next. You will then be prompted to enter your username, password, select your POP server and choose some other options for your mail settings in Gmail.

Use these settings to add a Hotmail email account:

  • POP server: pop3.live.com (Port 995)
  • User name: Your Windows Live ID, for example yourname@hotmail.com
  • Password: The password you usually use to sign in to Hotmail or Windows Live

Once you are done, click on Add Account. If you want to send email from the account you just added, make sure you click 'Yes. I want to be able to send mail as…". This allows you select an email address from a drop-down box.

So now, all email received from your other email accounts will be downloaded to your Gmail Account. This allows you to access all your emails in one easy location.

If you only have one Gmail Account and a lot of Hotmail accounts, I'd suggest to forward all your Hotmail account mail to one Hotmail Account as this forward is done almost instantly. The other advantage is if you have a lot of mail, downloading your mail to Gmail will be much quicker as it only has to connect to one account.

So now we have solved the problem of accessing all your mail in one location. But how do we now access these emails offline? If all our emails are being forwarded to one account, how do we split them up? I'll cover this in my next post. Watch out for it.

Soda can solar panel

 
 

Sent to you by Sparkie via Google Reader:

 
 

via MAKE Magazine by Chris Connors on 7/5/09

solar6.jpg

So you have a few extra cans left about the manse after the holiday party and are wondering what to do with them. How about building a solar panel? Free heat is good heat.

As air enters the 2 holes on the sides near the bottom, the sun is heating up the soda cans all painted black to absorb the heat. The cans have holes drilled in the bottom, so the air being drawn in at the bottom works its way through all the heated cans and gets hotter and hotter as it approaches the top. With convection, more and more air is drawn in through the bottom and the heat rises. A single hole drilled in the top of the frame is where all this heat comes out, and I have to tell you - it's friggin' hot and it comes flying out of there at full speed.

This could be a handy way to provide a bit of daytime heat to a shed or garage that it otherwise useless during the depth of winter.

4 Cool Fake Viruses to Make Your Friends Freak Out

 
 

Sent to you by Sparkie via Google Reader:

 
 

via MakeUseOf.com by Tim Watson on 7/5/09

There's nothing wrong with a harmless prank, especially when the victim is anyone but you. If you want to have some fun with your friends (or enemies for that matter), drop these cool fake viruses into the folder located at "C:Documents and SettingsAll UsersStart MenuStartup", then watch 'em squirm.

Although the following fake viruses may seem malicious to the unsuspecting, they are non-destructive to your computer system. So you don't have to worry about anything else and just enjoy the fun of making someone else panic!

Mix it up a little, don't forget to check out other "prank" posts on MakeUseOf like 4 Really Popular Prank Call Websites & How They Work and Two Great 'n Simple Nerdy Office Pranks to Play On Friends!

Let's get pranking, shall we?

(1) Fake Virus Batch File

I got this prank from WikiHow. I love it because it looks the most like an actual attack. Copy and paste the following into an open Notepad window, then save the file with any name you choose and an extension of ".bat"

Here's the code:

cls
:A
color 0a
cls
@echo off
echo Wscript.Sleep
echo Wscript.Sleep 5000>C:sleep5000.vbs
echo Wscript.Sleep 3000>C:sleep3000.vbs
echo Wscript.Sleep 4000>C:sleep4000.vbs
echo Wscript.Sleep 2000>C:sleep2000.vbs
cd %systemroot%System32
dir
cls
start /w wscript.exe C:sleep3000.vbs
echo Deleting Critical System Files…
echo del *.*
start /w wscript.exe C:sleep3000.vbs
echo Deletion Successful!
start /w wscript.exe C:sleep2000.vbs
echo:
echo:
echo:
echo Deleting Root Partition…
start /w wscript.exe C:sleep2000.vbs
echo del %SYSTEMROOT%
start /w wscript.exe C:sleep4000.vbs
echo Deletion Successful!
start /w wscript.exe C:sleep2000.vbs
echo:
echo:
echo:
echo Creating Directory h4x…
cd C:Documents and SettingsAll UsersStart MenuPrograms
mkdir h4x
start /w wscript.exe C:sleep3000.vbs
echo Directory Creation Successful!
echo:
echo:
echo:
echo Execution Attempt 1…
start /w wscript.exe C:sleep3000.vbs
echo cd C:Documents and SettingsAll UsersStart MenuProgramsStartuph4x
echo start hax.exe
start /w wscript.exe C:sleep3000.vbs
echo Virus Executed!
echo:
echo:
echo:
start /w wscript.exe C:sleep2000.vbs
echo Disabling Windows Firewall…
start /w wscript.exe C:sleep2000.vbs
echo Killing all processes…
start /w wscript.exe C:sleep2000.vbs
echo Allowing virus to boot from startup…
start /w wscript.exe C:sleep2000.vbs
echo:
echo:
echo Virus has been executed successfully!
start /w wscript.exe C:sleep2000.vbs
echo:
echo Have fun!
start /w wscript.exe C:sleep2000.vbs
pause
shutdown -s -t 10 -c "Your computer has committed suicide. Have a nice day."

Here's how it will look like once it is launched:

cool fake viruses

Your victim's PC will display messages as in the above image, and then initiate a shutdown sequence which can be stopped by entering "shutdown –a" in the Run command box. It looks bad, but is otherwise completely harmless.

(2) EICAR Test File

This test file, while harmless, will set off any good virus scanner. It's a test file to make sure that your anti-virus is vigilant, and is great for sending in an email.

fake virus programs

(3) Fake Format

I remember getting my brother once with a similar program. This cool fake virus perfectly simulates the Windows disk-format dialog, and cannot be closed or halted until it's ran its course. Once it's done, a message will be displayed informing the user that it was just a joke.

fake virus for windows

(4) Fake Delete

This is my favorite because, like its formatting counterpart, Fake Delete mimics the Windows file-delete dialogs. It even goes as far as using your actual file list instead of generic filenames! This also has the "it-was-all-a-joke" screen after it's done running.

When executing these pranks, please be considerate to whether your intended victim is mildly-panicky or really panicky, and whether your mark has some kind of panic disorder or heart problem. It's all fun and games until someone goes to the hospital. Otherwise, have fun!

Are you familiar with any cool fake viruses? What are your favorite computer pranks? Give us some of your most evil, yet good-natured, ideas in the comments.

Here are some more links to interesting Web pages I found by Twittering:

  • N3OX's Remote Tuner Control. N3OX has added some servo motors and controls to a manual antenna tuner so that he can move it closer to the antenna, but still control it from inside the shack. Very inexpensive solution.
  • Band Plans for 900 MHz and Above. KB9MWR feels that the future of ham radio is above 900 MHz. I don't know that I totally agree, but I do think we need to start thinking more about those bands. Give this a read.
  • Morse Code vs. Text Messaging. Chas Sprague, who's not a ham, ruminates on how Morse Code could make text messaging more efficient. I wholeheartedly agree! Someone get this man his ham ticket.
  • Ham Logging as a Service. There's been a lot of twittering about this KE9V blog post. I like the idea myself, and if I had more time, I might even take a crack at it. Anyone want to collaborate?
  • Planning a Digital ATV Station. After pondering a digital ATV station for the museum, I opted to go analog. If I'd seen this article first, I might have opted to stick it out and go digital.
