How to Disable Credit Card RFID
Submitted by altj on Thu, 04/09/2009 - 11:03I have an American Express Blue card which includes an RFID chip (because waving your card is so much easier than swiping it.) Unfortunately, if you have one of these (or a credit card with PayPass) your card is vulnerable.
Fortunately, it's easy to disable the RFID chip in your credit card. Here's what I do:
- Locate the chip - this is easy with my card since it is transparent and I can see the chip. If your card isn't transparent, the chip can be located by finding a slight divot in the plastic (usually on the back.)

- Stab the chip a few times with a sharp object - I use my trusty Leatherman Super Tool, but any sharp object will do. I stab from the back of the card because there's less plastic to go through to get to it. As you stab the chip, you'll feel some crunching or grinding. If you don't then you probably missed the chip.

- Now you can walk around confident your credit card information can't be read over the air by some nefarious evil doer.

I have a couple of coupon codes for 10% off your total purchase at Performance Bicycle.

Here are the codes:
10% off - 542

Short and sweet, but one of them should work! Please post a comment here if you use it so others don't waste their time trying them.
Fear == money
Submitted by altj on Mon, 03/23/2009 - 11:31The 2009 budget for homeland security is $50 billion.
The budget for the National Highway Traffic Safety Administration is about $1 billion.
From the article: "We fund terrorism prevention at about $17,000,000/fatality (i.e., $50 billion/3,000 fatalities) and accident prevention at about $25,000/fatality (i.e., $1 billion/40,000 fatalities)"
This is just one more example that the government's priorities are way messed up based on where it's spending money.
Amazon offers Reserved Instances
Submitted by altj on Thu, 03/12/2009 - 10:04Amazon announced today the availability of Reserved Instances. Basically, you pay a one-time fee and get a significant discount on the hourly rate for that instance.
Their rates are available here.
After doing some calculations on it, I figured out the break even point between the old "On-Demand Instances" and the new "Reserved Instances."
For the current 1 year term, the break-even point is 193 days. For the 3 year term, the break even point is 298 days. So basically, if you're going to be running a particular instance for much more than a year, you should probably sign up for the 3 year term.
Here's a brief comparison of the year by year costs for a small instance. I've only listed the small instance type since the costs for the other instance types are all proportional (e.g. large is 4x and xlarge is 8x.)
| 1st year costs | 2nd year costs | 3rd year costs | 3 year Total | |
| On Demand | $876.00 | $876.00 | $876.00 | $2,628.00 |
| 1 year term | $587.80 | $587.80 | $587.80 | $1,763.40 |
| 3 year term | $762.80 | $262.80 | $262.80 | $1,288.40 |
(I'm not sure why the spacing is so funky on this post with a table in it.)
Katadyn Guide Filter replacement leaking coal
Submitted by altj on Mon, 03/02/2009 - 13:20
I recently ordered a couple of replacement filters for my Katadyn Guide water filter through Amazon. They arrived today (yay! I love getting packages!) When I opened the box one of them looked normal but the other was pretty dirty and appeared to be leaking activated carbon (which is used in part of the filtering process.) When I gently shake it, something is rattling around inside the filter. There is no such noise when I gently shake the good one.
Looks like a defective filter to me. I immediately contacted the 3rd party seller (backcountry.com) through Amazon and Katadyn to see what can be done to resolve this. Obviously, my expectation is that it will be replaced at no cost to me.
I'll post updates here as things progress. If I were a betting man, I know who I'd put my money on but I don't want to spoil things for anyone else who may be reading.
Update: 3/3/09 - 10:40am: I just heard back from Katadyn. I'm a bit surprised that they beat backcountry.com in responding. Here's the response:
It is not necessarily defective. A few loose granules are completely normal. How many are there? If it is a smallish amount, that is ok, but if there is a lot of it, that might indicate a problem.
Please let me know.
Sincerely,
SarahMy reply:
Hi Sarah,
Thank you for your response.
It seems like more than just a few loose granules. I've posted a picture of it (click on the image to enlarge it.) http://altj.org/blog/katadyn-guide-filter-replacement-leaking-coal
Please let me know what you think.
Update: 3/3/09 - 11:44am: Another reply from Katadyn:
Yes, that is more than a few.
I will send you a replacement cartridge.
Would you like me to use the address in your original email?
Sincerely,
SarahAwesome! It looks like this is going to be resolved very quickly.
Update: 3/3/09 - 6:55pm: Received an email from Backcountry.com
Thanks for contacting us at Backcountry.com.
Sorry about that! If the item is damaged just give us a call at 1-800-409-4502 and we will be glad to help you out in returning this product and getting a replacement for it.
If you have any additional questions or concerns, please don’t hesitate to tell us, anytime… we don’t really sleep. Enjoy your day, we’ll talk to you later.
Update 3/4/09 - Called Backcountry.com
Told them about the problem and within 30 seconds they said a new one would be shipped out to me. They also sent me a shipping label to return the defective filter.
Update 3/5/09 - Received replacement from Backcountry.com
Wow, that was fast. I contacted Katadyn informing them that Backcountry.com has handled the problem and they don't need to send a replacement.
Backcountry.com wins! Although their initial response was slower, they took care of things efficiently. I'll be purchasing from them again!
RebuildStarted event detected on md device /dev/md0
Submitted by altj on Sun, 03/01/2009 - 09:41Logging into one of my systems, I saw the following in /proc/mdstat this morning.
Personalities : [raid1]
md0 : active raid1 sdc1[0] sdb1[1]
976559104 blocks [2/2] [UU]
[=========>...........] resync = 45.7% (446333440/976559104) finish=489.8min speed=18037K/sec
Unaware of a power failure or disk failure (these are pretty new disks) I did some digging. Looking through /var/log/daemon.log, I found these entries:
Mar 1 01:06:02 chewbacca mdadm: RebuildStarted event detected on md device /dev/md0
Mar 1 04:49:03 chewbacca mdadm: Rebuild20 event detected on md device /dev/md0
Mar 1 08:43:03 chewbacca mdadm: Rebuild40 event detected on md device /dev/md0
After some googling around, I found that on the first Sunday of every month at 1:06am, an array check (/usr/share/mdadm/checkarray) is run on Debian and Ubuntu systems. (see /etc/cron.d/mdadm)
For some reason it is listed in /proc/mdstat as a rebuild even though it is really a read-only operation to check the health of the array. Whew! Now I can go get ready for church.
Upgrading php5-memcache on Ubuntu (Intrepid)
Submitted by altj on Fri, 02/13/2009 - 16:01We were having a little problem on our webservers with php5-memcache when we try to utilize multiple memcached servers. The error was:
ALERT - canary mismatch on efree() - heap overflow detected (attacker '10.X.X.X', file '/path/to/file/index.php')
It didn't come up too frequently in the logs, but it was frequent enough to cause some concern.
As part of troubleshooting, I was tasked with upgrading php5-memcache on one of our test systems so that we could see if this resolved the issue. This turned out to be much easier than I thought. Here's what I did (as root):
apt-get install php5-dev
cp /usr/lib/php5/20060613+lfs/memcache.so /usr/lib/php5/20060613+lfs/memcache.so.bak
pecl install memcache-3.0.3
/etc/init.d/apache2 restart
That was it, we're running on 3.0.3 now and I'm crossing my fingers that resolves the issue we're seeing.
Comcast to stop throttling BitTorrent
Submitted by altj on Thu, 01/22/2009 - 11:43Comcast has changed its method of throttling bandwitch from targeting apps to just targeting high network traffic. This new "protocol-agnostic" will temporarily throttle heavy users if their area of the network is experiencing heavy traffic. "customers’ accounts must exceed a certain percentage of their upstream or downstream (both currently set at 70%) bandwidth for longer than a certain period of time, currently set at fifteen minutes."
Here's more information on the change as well as their FAQ.
